[0008] In the following detailed description, reference is made to the

accompanying drawings which form a part hereof, and in which is shown by way of illustration specific examples in which the disclosure may be practiced. It is to be understood that other examples may be utilized and structural or logical changes may be made without departing from the scope of the present disclosure. The following detailed description, therefore, is not to be taken in a limiting sense, and the scope of the present disclosure is defined by the appended claims. It is to be understood that features of the various examples described herein may be combined, in part or whole, with each other, unless specifically noted otherwise.

[0009] A first board (e.g., a first printed circuit board) may need to transmit one or multiple types of electrical signals and/or power to a second board (e.g., a second printed circuit board), such as serial data signals, Video Graphic Array (VGA) signals, DisplayPort (DP) signals, High-Definition Multimedia Interface (HDMI) signals, Universal Serial Bus (USB) signals (e.g., Dual USB signals, Type C signals, Type C 100W Power Delivery (PD) signals), Thunderboltâ„¢ signals (e.g., TBT 3.0 signals), 2.5G Local Area Network (LAN) signals, Fiber Network Interface Card (NIC) signals, and/or other signals. Each of the above signals may use a different number of pins to transmit the signals, thus resulting in board to board connectors designed specifically for each type of signal.

[0010] Accordingly, disclosed herein are board to board connectors for transmitting electrical signals between a first board and a second board (e.g., a first printed circuit board and a second printed circuit board). The board to board connectors include a first half of the connector to be attached to the first board and a second half of the connector to be attached to the second board. The first half of the connector includes two male connectors. The second half of the connector may include a female connector to couple to either one of the two male connectors or a single female connector to couple to both of the male connectors as described in further detail below. Therefore, the board to board connectors disclosed herein provide flexibility by enabling multiple system designs having different board to board signal requirements to use the same set of connectors.

[0011] Figure 1 A is a top view and Figure 1 B is a side view illustrating one example of a first half 100 of a board to board connector. First half 100 of the board to board connector includes a housing 102, a first male connector 104a including a first number of pins 106a, and a second male connector 104b including a second number of pins 106b. The second male connector 104b is aligned with the first male connector 104a. The first male connector 104a is configured to be removably electrically coupled to a first female connector (to be described below with reference to Figures 2A-2B) including a third number of pins equal to the first number. The second male connector 104b is configured to be removably electrically coupled to a second female connector (to be described below with reference to Figures 2A-2B) including a fourth number of pins equal to the second number. The first male connector 104a and the second male connector 104b are also configured to be removably electrically coupled to a single third female connector (to be described below with reference to Figures 3A-3B) including a fifth number of pins equal to the first number plus the second number.

[0012] The first number may be equal to the second number. In one example, the first number equals 60 and the second number equals 60. In other examples, the first number may be different from the second number. The first male connector 104a may be integral to the second male connector 104b via, for example, housing 102. Pins 106a of first male connector 104a are electrically coupled to corresponding pins 108a, which are configured to be electrically coupled to a first board. Likewise, pins 106b of second male connector 104b are electrically coupled to corresponding pins 108b, which are configured to be electrically coupled to a first board.

[0013] Flousing 102 may include posts 1 10 for aligning and/or attaching the first half 100 of the board to board connector to a first board. Flousing 102 also includes opposing sidewalls 1 12a along the length of first portion 100 and opposing sidewalls 1 12b along the width of the first portion 100. The sidewalls 1 12a and 112b define a socket 114. The first male connector 104a and the second male connector 104b are arranged within the socket 1 14 between the sidewalls 1 12a and 1 12b. While in this example, the sidewalls 1 12b have a greater height than the sidewalls 1 12a, in other examples, the sidewalls 1 12a and 1 12b may have the same height.

[0014] Figure 2A is a top view and Figure 2B is a side view illustrating one example of a second half 200 of a board to board connector. Second half 200 of the board to board connector includes a housing 202, a female connector 204 including a third number of pins 208. The female connector 204 is configured to be removably electrically coupled to a first male connector (e.g., 104a) or a second male connector (e.g., 104b). Accordingly, the third number of pins 208 may equal the first number of pins 106a and/or the second number of pins 106b. In one example, the third number equals 60.

[0015] Female connector 204 is configured such that when female connector 204 is removably electrically coupled to the first male connector 104a or the second male connector 104b, pins 208 of female connector 204 are electrically coupled to corresponding pins 106a or 106b of first male connector 104a or second male connector 104b, respectively. Pins 208 of the second portion 200 of the board to board connector are configured to be electrically coupled to a second board.

[0016] Flousing 202 may include posts 210 for aligning and/or attaching the second half 200 of the board to board connector to a second board. Flousing 202 also includes opposing sidewalls 212a along the length of second portion 200 and opposing sidewalls 212b along the width of the second portion 200.

The sidewalls 212a and 212b define female connector 204. Flousing 202 of the second half 200 of the board to board connector is configured to be at least partially removably received within socket 114 of the first half 100 of a board to board connector.

[0017] Figure 3A is a top view and Figure 3B is a side view illustrating another example of a second half 300 of a board to board connector. Second half 300 of the board to board connector includes a housing 302, a single female connector including a first portion 304a including a third number of pins 308a and a second portion 304b including a fourth number of pins 308b such that the single female connector includes a fifth number of pins equal to the third number plus the fourth number. The female connector 304a, 304b is configured to be removably electrically coupled to a first male connector (e.g., 104a) and a second male connector (e.g., 104b). Accordingly, the third number of pins 308a may equal the first number of pins 106a and the fourth number of pins 308b may equal the second number of pins 106b such that the fifth number of pins equals the first number plus the second number. In one example, the third number equals 60 and the fourth number equals 60 such that the fifth number equals 120.

[0018] Female connector 304a, 304b is configured such that when female connector 304a, 304b is removably electrically coupled to the first male connector 104a and the second male connector 104b, pins 308a of the first portion 304a are electrically coupled to corresponding pins 106a of the first male connector 104a, and pins 308b of the second portion 304b are electrically coupled to corresponding pins 106b of the second male connector 104b. Pins 308a and 308b of second portion 300 of the board to board connector are configured to be electrically coupled to a second board.

[0019] Housing 302 may include posts 310 for aligning and/or attaching the second half 300 of the board to board connector to a second board. Housing 302 also includes opposing sidewalls 312a along the length of second portion 300 and opposing sidewalls 312b along the width of the second portion 300.

The sidewalls 312a and 312b define the female connector 304a, 304b. Housing 302 of the second half 300 of the board to board connector is configured to be at least partially removably received within socket 1 14 of the first half 100 of a board to board connector.

[0020] Figure 4A is a schematic diagram illustrating one example of a board to board connector 400. Board to board connector 400 includes a first half 100 and a second half 200 as previously described and illustrated with reference to Figures 1 A-1 B and Figures 2A-2B, respectively. In this example, the second half 200 is removably electrically and mechanically coupled to the first male connector 104a (not visible) of the first half 100. [0021] Figure 4B is a schematic diagram illustrating one example of a board to board connector 402. Board to board connector 402 includes a first half 100 and a second half 200 as previously described and illustrated with reference to Figures 1 A-1 B and Figures 2A-2B, respectively. In this example, the second half 200 is removably electrically and mechanically coupled to the second male connector 104b (not visible) of the first half 100.

[0022] Figure 4C is a schematic diagram illustrating one example of a board to board connector 404. Board to board connector 404 includes a first half 100 and a second half 300 as previously described and illustrated with reference to Figures 1 A-1 B and Figures 3A-3B, respectively. In this example, the second half 300 is removably electrically and mechanically coupled to the first male connector 104a and the second male connector 104b of the first half 100.

[0023] Figure 4D illustrates a cross-sectional view of board to board connector 404 of Figure 4C. A similar cross-sectional view is also applicable to board to board connector 400 of Figure 4A and board to board connector 402 of Figure 4B. As illustrated in Figure 4D, the first male connector 104a engages the first portion 304a of the female connector such that the opposing sidewalls 312a of the female connector are between the opposing sidewalls 1 12a of the first half 100 of the board to board connector 404. With the first male connector 104a engaged with the first portion 304a of the female connector, pins 108a of first half 100 of the board to board connector 404 are electrically coupled to corresponding pins 308a of the second half 300 of the board to board connector 404.

[0024] Figure 5A is a simplified top view illustrating one example of a system 500 including a board to board connector 502. System 500 includes a first board 504, a second board 506, and board to board connector 502 electrically coupling the first board 504 to the second board 506. Board to board connector 502 may include board to board connector 400, 402, or 404 as previously described and illustrated with reference to Figures 4A-4D and as further described and illustrated with reference to the following Figures 5B-5D. While in this example first board 504 is larger than second board 506, in other examples, first board 504 may be the same size or larger than the second board 506. [0025] In one example, first board 504 is a mother board, and second board 506 is an input/output board. System 500 may be part of a tower computer, a desktop computer, a small form factor computer, a retail point of sale terminal, a thin client, a workstation, or another suitable system. Board to board connector 502 may pass one or multiple electrical signals and/or power between first board 504 and second board 506, such as serial data signals, VGA signals, DP signals, HDMI signals, USB signals (e.g., Dual USB signals, Type C signals, Type C 100W PD signals), Thunderboltâ„¢ signals (e.g., TBT 3.0 signals), 2.5G LAN signals, Fiber NIC signals, and/or other signals.

[0026] Figure 5B is a simplified side view illustrating one example of a system 510 including a board to board connector 400 as previously described and illustrated with reference to Figure 4A. In this example, the first board 504 includes the first half 100 of the board to board connector 400, and the second board 506 includes the second half 200 of the board to board connector 400. In other examples, the board to board connector 400 may be reversed such that the first board 504 includes the second half 200 of the board to board connector 400, and the second board 506 includes the first half 100 of the board to board connector 400. In this example, first board 504 may be a mother board, and second board 506 may be an input/output board including a serial port, a VGA port, a DP port, an FIDMI port, a Type C port, a Dual USB port, and/or another suitable port that may be electrically coupled to mother board 504 through board to board connector 400. Therefore, the first board 504 may transmit one of Serial, VGA, DP, FIDMI, Type C, and Dual USB signals through the first male connector 104a to the female connector 204.

[0027] Figure 5C is a simplified side view illustrating one example of a system 512 including a board to board connector 402 as previously described and illustrated with reference to Figure 4B. In this example, the first board 504 includes the first half 100 of the board to board connector 402, and the second board 506 includes the second half 200 of the board to board connector 402. In other examples, the board to board connector 402 may be reversed such that the first board 504 includes the second half 200 of the board to board connector 402, and the second board 506 includes the first half 100 of the board to board connector 402. In this example, first board 504 may be a mother board and second board 506 may be an input/output board including a 2.5G LAN port, a Fiber NIC port, and/or another suitable port that may be electrically coupled to mother board 504 through board to board connector 402. Therefore, the first board 504 may transmit one of 2.5G LAN and Fiber NIC signals through the second male connector 104b to the female connector 204.

[0028] Figure 5D is a simplified side view illustrating one example of a system 514 including a board to board connector 404 as previously described and illustrated with reference to Figure 4C. In this example, the first board 504 includes the first half 100 of the board to board connector 404, and the second board 506 includes the second half 300 of the board to board connector 404. In other examples, the board to board connector 404 may be reversed such that the first board 504 includes the second half 300 of the board to board connector 404, and the second board 506 includes the first half 100 of the board to board connector 404. In this example, first board 504 may be a mother board and second board 506 may be an input/output board including a TBT 3.0 port, a Type C 100W PD port, and/or another suitable port that may be electrically coupled to mother board 504 through board to board connector 404. Therefore, the first board 504 may transmit one of TBT 3.0 and Type C 100W PD signals through the first and second male connectors 104a and 104b to the female connector 304a, 304b.

[0029] Figure 6 is a flow diagram illustrating one example of a method 600 for fabricating a system, such as system 500, 510, 512, or 514 previously described and illustrated with reference to Figures 5A-5D.
