Description

Technical field

[0001] The utility model discloses an electric connector. [Background Technology]

[0002] For related known technologies, please refer to Chinese invention patent CN117096648A, which discloses an electrical connector comprising a housing and a terminal module. The housing is internally provided with a first mating cavity and a second mating cavity extending forward, as well as a receiving cavity extending rearward. The terminal module comprises an insulator and a pair of signal terminals, with the insulator received within the receiving cavity. The electrical connector also includes a positioning member, which is installed from bottom to top within the housing along a second elongated slot and covers the rear end of the insulator. It is apparent that the prior art lacks additional structure to secure the positioning member to the housing, failing to achieve stability for the overall electrical connector.

[0003] Therefore, it is necessary to provide an improved electrical connector to solve the above problems. [Utility Model Content]

[0004] The technical problem to be solved by the present invention is to provide an electrical connector which can ensure the stability of the overall structure of the electrical connector.

[0005] To achieve the above-mentioned purpose, the present invention adopts the following technical solutions: an electrical connector, comprising a metal seat, a terminal module and a back cover, wherein a receiving cavity is provided in the metal seat, the receiving cavity passes through from front to back, and the terminal module is inserted into the receiving cavity from back to front; the back cover comprises a main board portion that abuts against the terminal module in front and a pair of side plate portions connected to the lateral sides of the main board portion, the side plate portions are integrally provided with a latching protrusion protruding from the outer surface thereof, and the inner wall surface of the receiving cavity is provided with a buckle groove, when the back cover is inserted into the receiving cavity, the latching protrusion slides along the inner wall surface of the receiving cavity, at this time, the two side plate portions bend toward each other until the latching protrusion is stuck in the buckle groove, and the side plate portions provide rebound force.

[0006] Compared with the prior art, the present invention has the following beneficial effects: a pair of side panels are provided on both sides of the back cover, and the side panels are integrally provided with latching protrusions from their outer surfaces, so that the side panels undergo elastic deformation. When the latching protrusions snap into the buckle grooves, the side panels generate a rebound force, which allows the latching protrusions to be completely snapped into the buckle grooves, thereby ensuring that the back cover can be firmly fixed on the metal seat, thereby achieving the stability of the overall structure of the electrical connector.

[0016] The following specific embodiments will further illustrate the present invention in conjunction with the above-mentioned drawings. [Specific implementation method]

[0017] Ginseng Figures 1 to 7 As shown, the utility model discloses an electrical connector 100, including a metal base 10, a terminal module 20 and a back cover 30. A receiving cavity 11 is provided in the metal base 10, and the receiving cavity 11 passes through from front to back. The terminal module 20 is inserted into the receiving cavity 11 from back to front. The back cover 30 includes a main board portion 31 that abuts against the terminal module 20 in the front and a pair of side panels 32 connected to the lateral sides of the main board portion 31. The side panels 32 are integrally provided with a latching protrusion 33 protruding from their outer surfaces. The inner wall surface of the receiving cavity 11 is provided with a buckle groove 12. When the back cover 30 is inserted into the receiving cavity 11, the latching protrusion 33 slides along the inner wall surface of the receiving cavity 11. At this time, the two side panels 32 bend toward each other until the latching protrusion 33 is snapped into the buckle groove 12. The side panels 32 provide a rebound force, which can make the latching protrusion 33 completely snap into the buckle groove 12, thereby ensuring that the back cover 30 can be firmly fixed on the metal base 10.

[0018] Ginseng Figures 1 to 5 As shown, the metal base 10 includes a mounting portion 13 and a docking portion 14 extending forward from the mounting portion 13. The receiving cavity 11 passes through the docking portion 14 forward to form a docking cavity 111, and passes through the mounting portion 13 backward and downward to form a mounting cavity 112. The rear cover 30 is inserted into the mounting portion 13 from bottom to top. Figure 3 and Figure 4 As shown, the inner wall of the installation cavity 112 is provided with a recessed portion 113 along the outer surface of the side plate portion 32. The buckle groove 12 is located in the recessed portion 113. After the protrusion 33 rebounds into the buckle groove 12, the side plate portion 32 is entirely accommodated in the recessed portion 113. Figure 3 As shown, the side plate portion 32 is provided with an arc-shaped bending portion 321 integrally connected to the main plate portion 31, and the recessed portion 113 is provided with an arc-shaped groove 114 for accommodating the bending portion 321. The arc-shaped groove 114 is adjacent to the buckle groove 12 to guide the locking protrusion 33 to be snapped into the buckle groove 12. Figure 1 and Figure 5 As shown, the side plate portion 32 is provided with a pin portion 322 extending downward beyond the metal base 10 . The pin portion 322 is located directly below the locking protrusion 33 . When the pin portion 322 is soldered to the circuit board, it can keep the locking protrusion 33 stably locked in the buckle groove 12 .

[0019] Ginseng Figure 6 and Figure 7 As shown, the buckle groove 12 extends outward through the recessed portion 113. When viewed from the front-to-back direction, the outer edge of the latching protrusion 33 is located within the buckle groove 12 or is aligned with the outer edge of the buckle groove 12, and the upper and lower portions of the latching protrusion 33 both abut against the inner surface of the buckle groove 12, thereby limiting the upper and lower positions of the rear cover 30. In addition, the buckle groove 12 does not extend through the mounting portion 13 in the front-to-back direction to prevent the rear cover 30 from falling backwards from the metal base 10. The terminal module 20 includes a pair of terminals 21 and an insulating body 22 formed by integral injection molding that covers the terminals 21. One end of the terminal 21 is a contact portion 211 that extends beyond the insulating body 22. The contact portion 211 is located within the docking cavity 111. The other end of the terminal 21 is a solder foot 212 that extends beyond the metal base 10. Figure 7 As shown, from the top and bottom directions, the side plate portion 32 extends to both sides of the terminal module 20, and the solder legs 212 are located in the lateral range between the two leg portions 322. Figure 1 and Figure 2 As shown, both the solder leg 212 and the pin portion 322 are provided with a fisheye structure. The fisheye structure 213 of the solder leg 212 penetrates in the front-to-back direction, and the fisheye structure 323 of the pin portion 322 penetrates in the transverse direction. Therefore, when the electrical connector 100 is installed on a circuit board (not shown), the overall stability of the electrical connector 100 can be maintained.

[0020] In summary, the above are merely preferred embodiments of the present invention and should not be construed to limit the scope of the present invention. In other words, any simple equivalent changes and modifications made in accordance with the claims and the description of the present invention should still fall within the scope of the present invention.
