CROSS-REFERENCE TO RELATED APPLICATION

This application claims the benefit of Chinese Patent Application No. CN201710455276.2 filed on June 16, 2017 in the State Intellectual Property Office of China, the whole disclosure of which is incorporated herein by reference.

BACKGROUND OF THE INVENTION

Field of the Invention

Embodiments of the disclosure relate to a connector assembly.

Description of the Related Art

In some existing applications, a connector cannot be electrically connected to a wire of a cable directly, so it is necessary to solder the connector on a circuit board and electrically connect the connector to the wire of the cable through the circuit board. However, in the application, soldering pins and conductive traces on the circuit board electrically connected to the connector and the cable are directly exposed to outside, so that the entire product has poor electromagnetic shielding performance. In addition, when the cable is subjected to an external pulling force, the wire of the cable soldered to the circuit board is easily separated from the circuit board. Therefore, the entire product has poor tensile performance.

SUMMARY OF THE INVENTION

Embodiments of the disclosure have been made to overcome or alleviate at least one aspect of the above mentioned disadvantages.

According to one aspect of the disclosure, there is provided a connector assembly comprising: a connector comprising a shield housing, an insulation body accommodated in the shield housing and a conductive terminal held in the insulation body; a circuit board formed with a first soldering pin and a second soldering pin electrically connected with the first soldering pin thereon; and a cable comprising a wire having a conductor. The conductive terminal is soldered to the first soldering pin on the circuit board, and the conductor of the wire is soldered to the second soldering pin on the circuit board. The connector assembly further comprises an outer shield housing mounted on the circuit board by which the connector, the cable and the circuit board are covered.

According to an exemplary embodiment of the disclosure, the outer shield housing is formed with a crimp ring at a rear end thereof. The crimp ring is crimped over a conductive shield layer and an outer insulation layer of the cable.

According to another exemplary embodiment of the disclosure, the outer shield housing is further formed with an elastic sheet in elastically electrical contact with the shield housing of the connector so that the outer shield housing is electrically connected with the shield housing of the connector.

According to further another exemplary embodiment of the disclosure, the outer shield housing is mounted on the circuit board in a snap-fit manner.

According to yet another exemplary embodiment of the disclosure, the outer shield housing is further formed with at least one pair of elastic hooks on both sides thereof, respectively. The circuit board is formed with at least one slot. Each pair of elastic hooks are adapted to be snapped into one corresponding slot so as to secure the outer shield housing onto the circuit board.

According to still another exemplary embodiment of the disclosure, the shield housing of the connector is formed with at least one soldering leg on either side thereof. The circuit board is further formed with a soldering pad corresponding to the soldering leg. The soldering leg is soldered onto the soldering pad.

According to further another exemplary embodiment of the disclosure, the at least one soldering leg is formed with a leg portion thereon. The circuit board is further formed with a insertion hole corresponding to the leg portion. The leg portion is inserted into the insertion hole.

According to yet another exemplary embodiment of the disclosure, the connector comprises a plurality of electrically conductive terminals. The cable comprises a plurality of wires. The circuit board comprises a plurality of first soldering pins and a plurality of second soldering pins thereon. The plurality of electrically conductive terminals on the connector are soldered to the plurality of first soldering pins on the circuit board 200, respectively. The plurality of wires on the cable are soldered to the plurality of second soldering pins on the circuit board, respectively.

According to still another exemplary embodiment of the disclosure, the plurality of first soldering pins are arranged in a row. The plurality of second soldering pins are also arranged in a row. A row of first soldering pins are located in front of a row of second soldering pins with respect to the cable.

According to yet another exemplary embodiment of the disclosure, the plurality of first soldering pins are electrically connected to the plurality of second soldering pins through a plurality of electrically conductive traces formed on the circuit board, respectively.

In various embodiments of the disclosure as described above, the outer shield housing is mounted on the circuit board, and the connector, the cable and the circuit board are covered with the outer shield housing, so that the soldering pins and the conductive traces on the circuit board electrically connected with the connector and the cable are enclosed in the outer shield housing, thereby improving the electromagnetic shielding effect of the entire connector assembly.

In some exemplary embodiment of the disclosure, the outer shield housing is formed with a crimp ring at a rear end thereof. The crimp ring is crimped over the conductive shield layer and the outer insulation layer of the cable. Therefore, an external pulling force applied to the cable will be directly transmitted to the outer shield housing rather than being transmitted to the wire of the cable. Thus, it is possible to prevent the wire from being pulled away from the circuit board, thereby improving the tensile performance of the entire connector assembly.

Other objects and advantages of the disclosure will become apparent from the following description of the disclosure when taken in conjunction with the accompanying drawings, and may give a comprehensive understanding of the disclosure.
