Detailed Description

[0007] As mentioned, emitted electromagnetic radiation and/or noise can interfere with the performance of an electronic device and/or can negatively impact a user experience. As such, some approaches seek to employ shields (i.e., shielding) such as conductively coated (e.g., painted) plastic housings and/or metal cans, etc. to shield electrical components and thereby reduce electromagnetic radiation and/or noise emissions. For instance, some approaches employ spring clips that extend from an individual base to couple a shield to a circuit board and thereby to shield an electrical component. For example, a portion of a shield can be inserted in a gap between the spring clips and the spring clips can impart a clamping force on the portion of the shield inserted in the gap to couple the shield, via the spring clips, to a circuit hoard. [0008] However, a footprint of the spring clips can be large due to the presence of the plurality of spring clips (e.g., U-shaped spring clips) extending from the individual base. For instance, a wall thickness can be equal to a stun of the thicknesses of both spring clips plus the thickness of the shield (e.g., the thickness of the metal can). Moreover, such approaches may employ a rigid shield (e.g., a metal can) that is not flexible or bendable. Due to employing the spring clips and/or the rigid shield, such approaches can occupy a relatively large footprint in the electronic device.

[0009] As such, the disclosure is directed to shield clips, as detailed herein. For instance, shield clips can have an individual protrusion that extends from a base where respective individual protrusions of a first subset of the shield clips are to contact the first face of a shield and respective individual protrusions of a second subset of the shield clips are to contact the second face of the shield. Tims, a total thickness of a wall of shield mounting system employing the shield clips and a shield can be equal to a thickness of the shield and a thickness of an individual protrusion of a shield clip. As such, shield clips, can effectively retain a shield to reduce electromagnetic radiation and/or reduce noise emitted by an electronic device, and yet can occupy a smaller footprint in the electronic device as compared to other approaches such as those that employ the spring clips and/or rigid shields.

[0010] Fig. I A illustrates a view of an example of an electronic device 100 including a shield mounting system 101 having shield clips and a shield consistent with the disclosure. As used herein, the shield mounting system 101 refers to a combination of a shield 106 and a shield clips 132. The shield mounting system 101 can be employed in the electronic device 100 to mitigate electromagnetic radiation, noise, or both, emitted by an electrical component included in the electronic device 100, as detailed herein.

[0011] The electronic de vice 100 can be a mobile phone, a tablet, a laptop computer, a desktop computer, or combinations thereof. For instance, the electronic device 100 can be a laptop or a desktop computer, in some examples, the electronic device 100 can be an all-in- one (AIO) computer. As used herein, an AIO computer refers to a computer which integrates the internal components into the same ease as a display member and offers the touch input functionality of the tablet devices while also providing the processing power and viewing area of desktop computing systems.

[0012] The electronic de vice 100 can include a circuit board 102. Examples of circuit boards include a printed circuit board (PCB), among other types of circuit boards. An electrical component (e.g., electrical component 360, as detailed in Fig. 3) can be disposed on or otherwise coupled to the circuit board 102. As mentioned, the electrical component can emit electromagnetic radiation and/or noise which can interfere with the performance of the electronic device 100 and/or can otherwise negatively impact a user experience.

[0013] As such, the electronic device 100 can include a shield 106 that overlays or covers an electrical component in the electronic device 100. As used herein, a shield refers to a material that can block or reduce electromagnetic radiation, noise, or both. The shield 106 can be formed of a conductive and/or magnetic material, among other possibilities. For instance, the shield 106 can be formed of a metal, a material having a metal coating, or both , For example, the shield 106 can he formed of steel such as stainless steel and/or can be a material having a coating such as a zinc coating or other type of coating.

[0014] The shield 106 can be square or rectangular, as illustrated in Fig. IA,

However, other shapes are possible. For instance, the shield 106 can be circular and/or can include a dome or other type of shape.

[0015] Hie shield 106 can have a portion which forms a continuous loop or other continuous path along an entire perimeter of the shield 106. Stated differently, the portion which forms the continuous loop can be uninterrupted by the openings 152, which can be present in another portion of the shield 106. Having the shield 106 be formed of a continuous closed material can promote mitigation of electronic radiation, noise, or both, emitted by an electrical component of the electronic dev ice 100.

[0016] The shield can include a top face 112. The top face 112 of the shield 106 refers to a face that is most distal from the circuit board 102. The top face 112 of the shield 106 can be a continuous surface that is uninterrupted by the openings 152,

[0017] The shield 106 can include a first face (e.g., face 111-1), a second face (e.g., face 111-2) opposite the first face, and openings 152, as detailed herein, that extend through the first face and the second face. Similarly, the shield 106 can include a third face (e.g., face 111-3), a fourth face (e.g., face 111-4) opposite the third face, and the openings 152 that extend through the third face and the fourth face. As illustrated in Fig. 1A, the first face (e.g., face 111-1), the second face (e.g., face 111-2), the third face (e.g., face 111-3), and the fourth face (e.g., face 111-4) can together form a perimeter of the shield 106. While illustrated in Fig. 1 A as being substantially planar or straight for ease of illustration, the first face, the second face, the third face, and/or the fourth face can be bent such as being bent in a simple curve and/or being bent at an acute angle. For instance, the shield 106 can be bent (e.g., at an acute angle) at an axis extending through the openings 152 such that the shield is bent about or around the shield clips 132, as detailed herein. [0018] A portion of the perimeter of the shield 106 can be interrupted by the openings

152, as illustrated in Fig. 1A. For instance, the shield 106 can be a square or rectangular shield that has the openings 152. in faces such as the face ! 11-1, the face 111 -2, the face 111- 3, and/or the face 111-4 along a perimeter of the shield 106. For example, the shield 106 can have a plurality of openings in each face. For instance, opening 152-9, opening 152-10, opening 152-11 and opening 152-12 can be present m the face 111-3 of the shield 106.

[0019] Some or all of the faces that form the perimeter (or circumference) of the shield 106 can have the same or a different total quantity of openings 152. Similarly, some or all of the faces that form the perimeter (or circumference) of the shield 106 can have the openings 152 in the same relative positions. Having some or all of the same total quantity of openings 152 and/or same relative locations of the openings 152 in the faces along the perimeter of the shield 106 can promote retention of the shield 106 via the shield clips 132 and/or otherwise promote aspects of shield clips, as detailed herein.

[0020] The openings 152 can be formed of a slit, perforations, and/or another type of opening. For instance, the openings 152 can be elongated slits, as illustrated in Fig. 1A. As used herein, an elongated slit refers to an individual opening having a length that is greater than a width of the opening. As used herein, perforations refers to a row of holes aligned along a common axis. Employing elongated slits and/or perforations as the openings 152 can permit the shield 106 to block or reduce electromagnetic fields, noise, or both emitted from the electronic device 100, and yet can permit the shield 106 to bend or flex at various angles, as detailed herein, which can contribute to a reduction in an overall footprint (e.g., volume) occupied by die shield retention system 101 as compared to other approaches such as those detailed herein.

[0021] As mentioned, the electronic device 100 can include shield clips 132. As used herein, a shield clip refers to a mechanical structure including an individual protrusion extending from a base that is to promote coupling the shield 106 to the circuit board 102. Notably, shield clips 132 have an individual protrusion, m contrast to other approaches such those that employ a plurality of protrusions (e.g., a U-shaped spring clips) extending from an individual or common base. In this way, the shield clips 132 when employed in conjunction with the shield 106 can form the shield mounting system 101 that has a wall thickness that is comparatively thinner than other approaches such as those described herein.

[0022] The shield clips 132 can be uniformly spaced along the perimeter of the shield

106. For instance, each of the shield clips 132 can be spaced a given distance from the next shield clip along the perimeter of the shield 106. in some examples, each opposing face (e.g., the face 111-3 and the face 111 -4) can have the same number of shield clips that are uniformly spaced along the respective face, as illustrated in Fig. 1A.

[0023] As mentioned, the shield clips 132 can, notably, have an individual protrusion

(e.g., individual protrusion 336-3 as illustrated in Fig. 3) that extends from a base (e.g., base 333-3 as illustrated in Fig. 3). For instance, respective individual protrusions of a first subset of the shield clips 132 are to contact the first face 109 of the shield 106 and respective individual protrusions of a second subset of the shield clips 132 are to contact the second face 107 of the shield (e.g., as detailed in Fig. 2.4). As such, the shield clips 132, can effectively retain the shield 106 to reduce electromagnetic radiation and/or noise emitted by the electronic device 100, and yet can occupy a smaller footprint in the electronic device 100 as compared to other approaches such as those that employ the spring clips and/or die rigid shield, as detailed herein.

[0024] Fig. IB illustrates a view of a portion 150 of the electronic device 100 of Fig.

1 A. As illustrated in Fig. IB, the portion 150 includes a portion of the face 111 -3 of the electronic device 100. The face 111-3 can include openings 152 such as the opening 152-11 and the opening 152-12.

[0025] The openings 152 can be adjacent to a shield clip such as the shield dip 132-

10. For instance, each of the opening 152-11 and the opening 152-12 can be proximate to opposing ends of the shield dip 132-10. Having the openings 152 be proximate to opposing ends of a shield clip can permit the shield 106 to bend or flex relative to the opposing ends of a shield clip, in contrast to other approaches such as those that employ rigid shields (such as those without openings) and/or that do not employ shield clips, as detailed herein.

[0026] The shield 106 can have a total height 125 that extends from the circuit board

102 (or from a base of a protrusion) to the top face 112 of the shield 106. As illustrated in Fig. IB, the openings 152 can extend through a portion 126 of the total height 12.5 of the shield 106. Stated differently, each of the openings 152 can extend through the portion 126 but not ail of the total height 125 of the shield 106. Having the openings 152 extend through the portion 126 of but not all of the total height 12.5 of the shield 106 can provide a degree of freedom for the shield 106 to bend or flex along a perimeter of the shield 106 and thereby permit employing the shield clips 132, as detailed herein.

[0027] As illustrated in Fig. IB, each of the openings 152 can have the same height

(e.g,, equal to the portion 126 of the total height 125). Having the openings 152 with the same height can permit the shield 106 to readily undergo the same amount of bending or flexing about a respective shield clip and thereby promote various aspects herein. [0028] A shield clip such as the shield clip 132-10 can have a height 127 that is less than the total height 125 of the shield 106 and/or less than the portion 126 of the total height 125 of the shield 106. In addition, the height 127 of the shield clips 132 can be less than, greater than, or equal to the height 126 of the openings 152. For instance, as illustrated in Fig. I B tiie openings 152 can each have a height 126 that is greater than the height 127 of the shield clips 132 (e.g., the shield clip 132-10). Having the openings 152 have a height 126 that is greater than (or equal to) the height 127 of the shield clips can permit the shield 106 to readily bend or flex. For instance, the shield 106 can bend or flex about axis 155-1 extending through the opening 152-12, axis 155-2 extending through the opening 152-11, or both, and thereby permit the shield 106 to bend or flex about the shield clip 132-10 that is proximate to the opening 152-11 and the opening 152-12.

|O029j The openings 152 can have a width that is sufficient to ensure the shield 106 blocks electromagnetic radiation and noise, and yet is suitable to permit the shield 106 to bend or flex, as described herein , For instance, the opening 152-11 can have a width 12.5 such that adjacent opposing surface across the width 125 are in contact with each other (e.g.., when the shield 106 is not bent or flexed) and/or are spaced less than a threshold distance apart (e.g., when the shield is bent of flexed). Stated differently, the width of each of the openings 132 can be less than or equal to a threshold distance. For example, the width of each of the openings 132 can be less than or equal to 1 millimeter, 0.8 millimeters, 0.5 millimeters, 0.3 millimeters, or 0.1 millimeters, among other possible values of the threshold distance. In som e examples, the width of the openings 132 can vary depending on an amount of bending or flexing of the shield 106. In such instances, the width of the openings 132 can be less than a threshold distance w hen the shield 106 is bent or flexed (and can also be less than the threshold distance when the shield 106 is not bent or flexed).

[0030] Fig. 2A illustrates a top view (omitting the top face 112) of the electronic device 200. As illustrated in Fig. 2.4, a plurality of shield clips including shield clips 232-1, shield clip 232-2, shield clip 232-3, shield clip 232-4, shield clip 232-5, shield clip 232-6, shield clip 232.-7, shield clip 232-8, shield clip 232-9, and shield clip 232-10 (hereinafter referred to as shield clips 232) can be employed to couple the shield 206 to a circuit board (e.g., circuit board 102 as illustrated in Fig. 1A). While illustrated as a total often shield clips 232, the total number and/or a relative location of the shield clips 232 can be varied.

[0031] The shield clips 232 can include a planar face that is to contact the first face

209 or a second face 207 of the shield 206. As illustrated in Fig. 2A, a first subset of the shield clips 232 such as shield clip 232-3, shield clip 232-5, shield clip 232-7, and shield clip 232-9 are to contact the first (inner) face 209 of the shield 206. For instance, the first subset of the shield clips 232 can have individual protrusions with respective planar faces such as face 234-3, face 234-5, face 2.34-7, and face 234-9 that are to contact the first face 209 of the shield. Similarly, a second subset of the shield clips 232 such as shield clip 232-1, shield clip 232-2, shield clip 232-4, shield clip 232-6, shield clip 232-8, and shield clip 232-10 are to contact the second (outer) face 2.07 of the shield 206. For instance, the first subset of the shield clips 232 can have individual protrusions with respective planar faces such as face 234-1, face 234-2, face 234-4, face 234-6, face 234-8, and face 234-10 that are to contact the second face 207 of the shield 206.

[0032] The shield clips of the first subset of the shield clips 232 and shield clips of the second subset of the shield clips 232 can alternate along a face of the shield 206. For instance, the shield clips 232-7 to 232-10 can alternate between contacting the first face 209 and the second face 207 of the shield 206. Having the first subset of the shield clips and shield clips of the second subset of the shield dips 2.32 alternate along a face of the shield 206 can promote bending or flexing of the shield 206, as detailed herein.

[0033] That is, for ease of illustration faces 111-1, 111-2, 111-3, and 111-4 are illustrated as straight faces m Fig. 1A and Fig. IB, howe ver, a face of the shield 206 can be bent at various angles. For instance, the shield 206 can be bent or flexed at or near an axis extending through the openings 252 that are adjacent to shield clips 232, as illustrated in Fig. 2A. For instance, the shield 206 can be bent at an acute angle. As used herein, an acute angle refers to an angle that is less than 90 degrees. For instance, the shield 206 eau be bent at an angle that is in a range from 10 to 60 degrees, among other possibilities. For ease of illustration, the shield 206 is illustrated as including linear segments that are bent at acute angles. However, it is understood that the shield 206, as described herein, can be a continuous dosed material having portions of which that are bent in a curved or arcuate m anner.

[0034] A thickness 228 of a wall (formed of a combination of a shield clip and the shield 206) of the shield mounting system 201 can be equal to a thickness of the shield 206 and a thickness of the individual protrusion of the shield clip. For instance, the thickness 228 of a wall of the shield mounting system can be equal to a sum of a thickness of the shield and a thickness of a respective individual protrusion of the respective individual protrusions of the first subset of the shield clips, or a sum of the thickness of the shield and a thickness of a respective individual protrusion of the respective individual protrusions of the second subset of the shield clips. [0035] The shield clips 232 can be arranged in pairs. As used herein, a pair of shield dips refers to two adjacent shield clips located along a face of a perimeter of the shield 206. For example, the shield clip 232-9 and the shield clip 232-10 can form a pair of shield clips along the face 211-3. Similarly, the face 211-1, the face 211-2, and/or the face 211-4 can include a pair of shield clips. The pair of shield clips can include a first shield dip of the first subset of shield dips and a second shield clip of the second subset of shield dips. As illustrated in Fig. 2A, an opening (e.g., opening 252-11) can be located between respective shield clips of a pair of shield clips.

[0036] Tire shield 206 can be bent (e.g., deformed) at an acute angle having a first magnitude in a first direction at a first pair of shield clips (e.g., the shield clip 2.32-7 and the shield clip 232-8). In such examples, the shield 206 can be bent at an acute angle having a second magnitude in a second direction that is opposite the first direction at a second pair of shield dips (e.g., the shield dip 232-8 and the shield clip 232-9). For instance, a bend at the first angle can be equal in magnitude but opposite in direction as compared to the magnitude and the direction of the bend at the second angle. In this way, the shield 206 can be interweaved between respective pairs of shield clips and promote aspects herein such as providing a shield retention system having a thinner profile as compared to other approaches such as those that employ U-shaped spring clips.

|O037j Fig. 2B illustrates a pair of shield clips consistent with the disclosure. As mentioned, the shield clips 2.32 can include pairs of shield clips. The shield clip 232-9 and the shield clip 232.-10 can form a pair of shield clips. The pair of shield clips can be spaced a distance 222 apart along an axis (e.g., axis 221 as illustrated in Fig. 2A). That is, each shield clip of the pair of shield clips can have a respective base such as base 233-1 and base 233-2. The respecti ve bases can each be coupled to the first face 203 of the circuit board 202 at a different location such that the respective bases are spaced the distance 222. apart. Thus, a first shield clip (e.g., the shield clip 232-9) can include an individual protrusion having the first face and the base 233-1 coupled to the first face 203 of the circuit board 202 at a first location 235-1, while a second shield clip (e.g,, the shield clip 232-10) can include an individual protrusion having the second face and the base 233-2 coupled to the first face 203 of the circuit board 202 at a second location 235-2. Notably, having the pairs of shield clips be spaced the distance 222 apart can permit the shield 206 (omitted m Fig. 2B so as to not occlude aspects in Fig. 2B) to be interweaved between the shield clips 232 and thereby promote aspects herein such as providing the shield retention system 201 having a thinner wall/profile as compared to other approaches such as those that employ U-shaped spring clips.

[0038] The shield clips 232 can be non -removably coupled to the circuit board 202.

For instance, the shield clips 232 can be non-removably coupled to the first (top) face 203 of tiie circuit board 202. Examples of non-removably coupling the shield clips 232 to the circuit board 202 include soldering, gluing, or otherwise non-removably coupling the shield clips 232 to the circuit hoard 2.02, However, in some examples, the shield clips 232 can be removable coupled to the circuit board 202 via a mechanical fastener (e.g., via a screw, bolt, friction/snap/interference fit, etc.).

[0039] Fig. 3 illustrates a section view (as taken along section line 229 in Fig. 2A) of an example of the electronic device 300 including the shield mounting system 301 having shield clips and a shield consistent with the disclosure. As illustrated in Fig. 3, the electronic de vice 300 can include an electrical component 360 that emits electromagnetic radiation, noise, or both. The emitted electromagnetic radiation, noise, or both are represented by element identifier 333 as illustrated in Fig. 3. Hie electrical component 360 can be a processing unit, a memory component, or other type of electrical component. For instance, the electrical component 360 can be a Random-Access Memory ⁷ such as a Synchronous dynamic random-access memory (synchronous dynamic RAM or SDRAM), among other possibilities.

[0040] As mentioned, the shield clips 332 can include an individual protrusion extending from a base. For instance, the shield clip 332-3 can include an individual protrusion 336-3 extending from the base 333-3 while the shield clip 332-6 can include an individual protrusion 336-6 extending from the base 333-6. The individual protrusions of respective shield clips of the shield clips 332 can together couple the shield 306 to the circuit board 302 (and/or to a base of a shield clip) and thereby can encompass the electrical component 360 to mitigate the electronic radiation, noise, or both 333 emitted by the electronic de vice 300.

[0041] In the foregoing detailed description of the disclosure, reference is made to the accompanying drawings that fonn a part hereof, and in which is shown by way of illustration how examples of the disclosure can be practiced. These examples are described in sufficient detail to enable those of ordinary ⁷ skill m the art to practice the examples of this disclosure, and it is to be understood that other examples (e.g., having a different thickness) can be utilized and that process, electrical, and/or structural changes can be made without departing from the scope of the disclosure. [0042] The figures herein follow a numbering convention in which the first digit corresponds to the drawing figure number and the remaining digits identify an element or component in the drawing. For example, reference numeral 101 can refer to element 101 in Fig. 1 and an analogous element can be identified by reference numeral 201 in Fig. 2. Elements shown in the various figures herein can be added, exchanged, and/or eliminated to provide additional examples of the disclosure, in addition, the proportion and the relative scale of the elements provided in the figures are intended to illustrate the examples of the disclosure, and should not be taken in a limiting sense.
