Description

Technical Field

[0001] This application relates to the field of electrical connections, and more particularly to a charging dock. Background Technology

[0002] In existing technology, charging docks include a housing and a power terminal module. One installation method involves inserting the power terminal module into the housing and connecting it via a connector (e.g., screws). However, this installation method is time-consuming, labor-intensive, and difficult to disassemble. Another installation method involves a spring clip on the power terminal module, which directly clips onto the housing to securely connect the power terminal module and the housing. However, because the spring clip locally applies force to the front of the power terminal module, when the power terminal module is connected to a cable and the cable is under stress, the cable may cause the power terminal module to tilt relative to the housing. Utility Model Content

[0003] The purpose of this utility model is to solve at least one aspect of the aforementioned problems and defects existing in the prior art.

[0004] According to one aspect of the present invention, a charging dock is provided. The charging dock includes a housing and a power terminal module.

[0005] According to an exemplary embodiment of the present invention, a plurality of raised ribs are formed on the inner circumferential surface of the socket of the housing. The plurality of raised ribs extend along the axial direction of the socket and are spaced apart in the circumferential direction of the socket. The plurality of raised ribs are located in front of the positioning part and abut against the outer circumferential surface of the main body of the power terminal to securely hold the power terminal module in the socket.

[0006] According to an exemplary embodiment of the present invention, the positioning part is an injection-molded part that is injection-molded into or assembled onto the rear end of the power terminal.

The charging dock also includes a locking member, which is pluggably inserted into the mounting groove along the height direction and adapted to abut against a power terminal module inserted into the socket to lock the power terminal module in the socket of the housing.

[0008] According to another exemplary embodiment of the present invention, the locking spring has a front abutment wall adapted to contact the annular recess, the included angle ø between the front abutment wall and the axial direction of the insertion hole being less than 90°, so as not to prevent the power terminal module from disengaging from the housing longitudinally rearward.

[0009] According to another exemplary embodiment of the present invention, the cross-section of the rib is semi-circular.

[0010] According to another exemplary embodiment of the present invention, a portion of the locking member is inserted into the annular recess to engage with the annular recess.

[0011] According to another exemplary embodiment of the present invention, the mounting groove has a front wall and a rear wall opposite each other in the longitudinal direction of the housing. The front wall and the rear wall extend in the height direction. The insertion hole penetrates the front wall and has a front circumferential wall extending forward from the front wall, and the rib is formed on the front circumferential wall.

The positioning portion of the power terminal module has a limiting protrusion adapted to abut against the rear end face of the rear circumferential wall to axially position the power terminal module.

[0013] According to another exemplary embodiment of the present invention, the charging socket further includes a first sealing ring. The first sealing ring is disposed in the socket and is adapted to be pressed between the housing and the power terminal module to achieve a seal between the two.

[0014] According to another exemplary embodiment of the present invention, the power terminal module includes a cylindrical body portion located in front of the annular recess. The first sealing ring is pressed between the inner wall of the rear circumferential wall and the circumferential wall of the body portion.

[0015] According to another exemplary embodiment of the present invention, the locking spring extends rearward from the rear periphery toward the wall.

[0016] According to another exemplary embodiment of the present invention, the locking member includes a locking body and at least two locking portions, the at least two locking portions being disposed and connected below the locking body. At least two insertion holes are formed on the housing, the at least two insertion holes being arranged side-by-side in the lateral direction of the housing. The mounting groove extends laterally along the housing and across the at least two insertion holes, and the at least two locking portions extend into the at least two insertion holes respectively in the height direction for locking at least two power terminal modules into the at least two insertion holes respectively.
