[0034] The following description of at least one exemplary embodiment is merely illustrative and in no way restrictive of the present invention or its application or use.

[0035] Techniques, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be regarded as part of the specification.

[0036] In all examples shown and discussed herein, any specific values should be construed as merely exemplary and not as limitations. Thus, other examples of the exemplary embodiments may have different values.

[0037] A plug connector, as Figures 1-3 shown, includes a sheath 30, a terminal assembly 10 installed in the terminal cavity 301 of the sheath 30, and a TPA part 20 for secondary locking of the terminal assembly 10. Here, it should be noted that the primary locking of the terminal assembly 10 is achieved by means of a primary locking cantilever 50 provided on the sheath 30. One end of the primary locking cantilever 50 is connected to the inner wall of the terminal cavity 301, and the other end extends into the terminal cavity 301. When the terminal assembly 10 is inserted into the terminal cavity 301, the stop ring groove 101 provided circumferentially on the terminal assembly 10 is snap-fitted with the extending end of the primary locking cantilever 50 to achieve the primary locking of the terminal assembly 10. The TPA part 20 is further provided for secondary locking on the basis of the primary locking to achieve stable retention of the terminal assembly 10 and prevent the terminal assembly 10 from withdrawing from the sheath 30 when subjected to a large external force.

[0038] like Figures 1-3 As shown, the TPA component 20 includes a main body 201 and a clamping portion 202 symmetrically arranged on both sides of the main body 201. A clamping groove 302 is provided on the outer wall of the sheath 30 along the direction 40 in which the TPA component is installed into the sheath. The clamping portion 202 is slidably arranged in the clamping groove 302, and a mutually cooperating clamping structure is provided between the clamping portion 202 and the clamping groove 302 to realize the positioning of the TPA component 20 in the pre-installed position and the locked position; specifically, a pre-installed groove 303 and a locking groove 304 are sequentially provided on the bottom wall of the clamping groove 302 along the direction 40 in which the TPA component is installed into the sheath, and a locking block 204 is provided on the inner wall of the clamping portion 202. During the process of installing the TPA component 20 into the sheath 30, the locking block 204 is successively clamped and cooperated with the pre-installed groove 303 and the locking groove 304 to realize the positioning of the TPA component 20 in the pre-installed position and the locked position.

[0039] Further, if Figure 3 As shown, a stopper 203 is provided on the inner wall of the main body 201, and the side of the stopper 203 facing the terminal assembly 10 has an arc-shaped surface 206. Correspondingly, an overhanging groove 307 communicating with the terminal cavity 301 is provided on the sleeve 30, and the clamping portion 202 enters the terminal cavity 301 through the overhanging groove 307; when the TPA component 20 is in the pre-installed position, the stopper 203 and the terminal assembly 10 are independent of each other and there is no interference relationship. At this time, the terminal assembly 10 can be smoothly installed in the terminal cavity 301 of the sleeve 30, and then the TPA component 20 is pushed to move the TPA component 20 to the locked position. When the TPA component 20 is in the locked position, the stopper 203 is engaged with the terminal assembly 10, specifically, it is engaged with the stopper ring groove 101 circumferentially provided on the terminal assembly 10 to prevent the terminal assembly 10 from withdrawing from the sleeve 30. For details, please refer to Figure 4 and Figure 5 Compared with the existing TPA component 20 in which the clamping portion 202 is clamped with the inner wall of the sheath 30, the present invention clamps the clamping portion 202 of the TPA component 20 with the outer wall of the sheath 30, thereby facilitating the disassembly of the TPA component 20 and further facilitating the replacement of the key position of the HSD connector.

[0040] In one embodiment, in order to facilitate the sliding of the TPA member 20 in the snap-fit groove 302, as shown in FIG. Figure 2 and Figure 3As shown, a guiding groove 305 is provided along the direction 40 in which the TPA part is inserted into the sheath on the bottom wall of the clamping groove 302, and a guiding rib 205 that cooperates with the guiding groove 305 is provided on the inner wall of the clamping part 202. When the TPA part 20 switches between the pre-installed position and the locked position, the guiding groove 305 and the guiding rib 205 play a guiding role. Further, the guiding rib 205 and the locking block 204 are perpendicularly arranged and are distributed in an L shape, thereby improving the structural strength of the two.

[0041] In one embodiment, as Figure 1 and Figure 2 shown, the tops of the two clamping grooves 302 are communicated through a connecting groove 306. When the TPA part 20 is in the locked position, at least part of the main body part 201 is embedded in the connecting groove 306. Specifically, the two clamping grooves 302 and the connecting groove 306 together form a U-shaped groove structure that matches the shape of the TPA part 20. When the TPA part 20 is in the locked position, the TPA part 20 is integrally embedded in the U-shaped groove structure, thereby effectively preventing the operator from accidentally touching it.

[0042] In one embodiment, as Figures 1-3 shown, at least one anti-misalignment piece 70 is provided at one end of the TPA part 20 facing the socket connector (not shown in the figure). Correspondingly, a receiving groove 70 for receiving the anti-misalignment piece 60 is provided on the sheath 30. When the TPA part 20 is in the pre-installed position, the anti-misalignment piece 60 is located directly above the receiving groove 70, specifically on the insertion path of the socket connector (not shown in the figure) into the plug connector 1, so as to prevent the plug connector 1 and the socket connector (not shown in the figure) from being plugged together. Only when the TPA part 20 is in the locked position, the anti-misalignment piece 60 is exactly embedded in the receiving groove 70. For details, please refer to Figure 1 ; At this time, the socket connector (not shown in the figure) can be smoothly inserted into the plug connector 1 to achieve the smooth assembly of the two, thereby preventing the operator from assembling the plug and the socket when the terminal assembly 10 is not installed in place or is missing, resulting in connector failure or poor performance. In addition, the anti-misalignment piece 70 can also prevent the TPA part 20 from being misinserted.

[0043] The present utility model further provides a plug connector installation structure, as Figure 6As shown, it includes a fixing member 2 and the above-mentioned plug connector 1. A fixing groove 5 is circumferentially provided on the outer wall of the sheath 30, and a fixing hole 3 is provided on the fixing member 2. A connecting belt 4 is circumferentially arranged in the fixing groove 5 and the fixing hole 3. When it is necessary to fix the plug connector 1 to the vehicle body, the plug connector 1 is fixedly connected to the fixing member 2 through the connecting belt 4 circumferentially arranged in the fixing groove 5, and then the fixing member 2 is fixed to the vehicle body, thus facilitating the fixing of the plug connector of the present utility model. Generally, the fixing member 2 is a buckle, a sheet metal hole adapted to the buckle is provided on the vehicle body, and the connecting belt 4 is a cable tie.
