[0029] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0030] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0031] An integrated connector, such as Figure 1-Figure 5As shown, it includes a locking member 20, a sheath 30 with a terminal accommodating cavity 301, and a terminal 10 installed inside the terminal accommodating cavity 301. A one-time lock cantilever 308 is formed on the inner wall of the terminal accommodating cavity 301 along the direction 40 in which the locking member is installed into the sheath. The terminal 10 has a clamping area 101 that is clamped and matched with the one-time lock cantilever 308. After the terminal 10 is installed in the terminal accommodating cavity 301, the clamping area 101 provided on the terminal 10 is clamped and matched with the one-time lock cantilever 308 to achieve a one-time lock of the terminal 10; a clamping arm 302 is provided on one of the outer walls of the sheath 30, one end of the clamping arm 302 is connected to the outer wall of the sheath 30, and the other end is cantilevered. The locking member 20 is detachably provided at the entrance 307 of the terminal accommodating cavity to prevent the terminal 10 from withdrawing from the sheath 30. For details, please refer to Figure 5 , thereby achieving secondary locking of terminal 10.

[0032] like Figure 1-Figure 5 The latch 302 is locked and locked in place when the latch 30 is unlocked, so the latch 302 is locked and locked in place when the latch 30 is unlocked. Figure 3 .

[0033] In summary, the utility model integrates the secondary lock structure (TPA) of the terminal 10 and the secondary lock structure (CPA) of the connector. Through one part, namely the locking member 20, the secondary lock functions of the terminal 10 and the connector can be simultaneously realized. The structure is simple and easy to install, and can be disassembled repeatedly, which significantly improves the reliability of the connector and reduces the cost of the connector.

[0034] In one embodiment, if Figure 1 and Figure 2 As shown, the sleeve 30 is extended with two clamping plates 303 at the entrance 307 of the terminal accommodating cavity. The two clamping plates 303 are distributed on both sides of the clamping arm 302 and are arranged opposite to each other. The locking member 20 and the two clamping plates 303 are clamped together. Specifically, a clamping groove 304 is provided on the clamping plate 303, and a clamping block 202 is correspondingly provided on the outer wall of the locking member 20. The clamping plate 303 and the locking member 20 are clamped together through the mutually cooperating clamping groove 304 and the clamping block 202.

[0035] Further, if Figure 2 and Figure 3 As shown, the housing 30 is further provided with at least one positioning plate 305 extending from the entrance 307 of the terminal accommodating cavity. The locking member 20 is provided with a positioning groove 203 for accommodating the positioning plate 305 on the side facing the housing 30. After the locking member 20 is installed in the housing 30, the positioning plate 305 is inserted into the positioning groove 203. For details, please refer to Figure 5 The positioning plate 305 and the positioning groove 203 cooperate with each other, thereby playing a guiding and positioning role in the process of the locking member 20 being installed into the sleeve 30; the positioning plate 305 is vertically arranged between the two clamping plates 303, and the sleeve 30, the two clamping plates 303 and the positioning plate 305 are integrally injection molded to reduce the manufacturing cost of the sleeve 30 and the connector.

[0036] In order to achieve the best use effect, Figure 3 As shown, the positioning groove 203 is located directly below the overhang portion 201. After the locking member 20 is installed in the sheath 30, the positioning plate 305 is supported on the bottom of the overhang portion 201. For details, please refer to Figure 4 and Figure 5 , thereby preventing the locking member 20 from moving downward after assembly. Figure 1-Figure 5 As shown, among the two side walls of the locking member 20 that cooperate with the clamping plate 303, at least one side wall is formed with a guide portion 204 that slides with the side wall of the clamping plate 303. During the process of installing the locking member 20 into the sheath 30, the side wall of the clamping plate 303 cooperates with the guide portion 204 to guide the installation of the locking member 20. The setting of the guide portion 204, on the one hand, serves the purpose of guiding the installation of the locking member 20, and on the other hand, prevents the locking member 20 from moving upward after assembly, that is, after the locking member 20 is assembled, the upward and downward movements of the locking member 20 are limited by the positioning plate 305 and the guide portion 204 respectively to prevent it from shaking after assembly.

[0037] In the present utility model, Figure 1-Figure 5 As shown, the guide portion 204 is long and extends along the direction 40 in which the locking member is installed in the sheath. The end of the guide portion 204 facing the sheath 30 extends to the outside of the locking member 20, and the sheath 30 is provided with a receiving groove 306 that matches the guide portion 204. After the locking member 20 is installed in the sheath 30, the end of the guide portion 204 facing the sheath 30 is inserted into the receiving groove 306. For details, please refer to Figure 1 and Figure 4 , so that the assembly of the locking member 20 can be positioned.

[0038] In one embodiment, the locking member 20 is provided with at least one observation window 205 that partially exposes the terminal 10. It should be noted that the setting of the observation window 205 is mainly to expose the wire-pressing end of the terminal 10 so that the loading condition of the terminal 10 and the connection condition of the terminal 10 and the cable can be observed. Therefore, when setting the observation window 205, those skilled in the art should set it without affecting the secondary lock of the locking member 20 on the terminal 10. The utility model further provides a setting method of the observation window 205, specifically: Figure 3 As shown, one of the two side walls of the locking member 20 that is not engaged with the clamping plate 303 is recessed inward to form an observation window 205. Since there are generally multiple terminals 10 in the connector and they are arranged side by side, the observation window 205 in this embodiment also has multiple terminals 10 and is arranged one-to-one with the multiple terminals 10, forming an observation window structure similar to a wave shape.

[0039] Further, if Figure 1-Figure 3 As shown, of the two side walls of the locking member 20 that are not engaged with the snap-on plate 303, the other side wall is recessed inward to form a collapsed groove 206 for facilitating the disassembly of the locking member 20. When disassembling the locking member 20, the operator's fingers can partially enter the collapsed groove 206, thereby increasing the friction with the locking member 20 and facilitating the disassembly of the locking member 20.

[0040] Although some specific embodiments of the present invention have been described in detail through examples, those skilled in the art will appreciate that the above examples are for illustration only and are not intended to limit the scope of the present invention. Those skilled in the art will appreciate that modifications may be made to the above embodiments without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
