[0026] Referring to Figures 1-5 , the male connector includes a housing 1, at least one terminal assembly 2, at least one compression locking member 3 and a sealing assembly 4.

[0027] Referring to Figure 2 and Figure 3 , the housing 1 is provided with a mating end 11 and a wire end 12 in the first direction M. The mating end 11 refers to the end of the housing 1 close to the female connector, and the wire end 12 refers to the end of the housing 1 away from the female connector for accommodating the passage of the wire.

[0028] Referring to Figure 2 and Figure 3The housing 1 is provided with at least one receiving cavity 13, and each receiving cavity 13 extends through the housing 1 along the first direction M. In this embodiment, the housing 1 is provided with four receiving cavities 13, and the four receiving cavities 13 are arranged in two rows and two columns along the second direction N and the third direction P.

[0029] Referring to Figure 4 and Figure 5 , the cavity wall of each receiving cavity 13 is provided with at least one first limiting part 14. In this embodiment, the first limiting part 14 comprises an elastic hook.

[0030] Referring to Figure 2 and Figure 3 , the terminal assembly 2 is arranged in one-to-one correspondence with the receiving cavity 13, and each terminal assembly 2 extends into the receiving cavity 13 from the wire end 12. In other words, each terminal assembly 2 extends into one receiving cavity 13 from the wire end 12. In this embodiment, the four terminal assemblies 2 extend into the four receiving cavities 13 in one-to-one correspondence.

[0031] Referring to Figure 2 and Figure 3 , the outer wall of each terminal assembly 2 is provided with at least one second limiting part 21, and the second limiting part 21 cooperates with the first limiting part 14 to lock the terminal assembly 2 in the receiving cavity 13. In this embodiment, the second limiting part 21 comprises a limiting step, and the first limiting part 14 abuts against one side of the limiting step close to the wire end 12 to block the movement of the terminal assembly 2 towards the wire end 12.

[0032] Referring to Figures 2-5 , each terminal assembly 2 comprises a terminal 22 and a wire 23, the terminal 22 is arranged in the receiving cavity 13, and the wire 23 is electrically connected to one side of the terminal 22 close to the sealing assembly 4 and extends out of the receiving cavity 13. Specifically, the second limiting part 21 is arranged on the outer wall of the terminal 22.

[0033] Referring to Figures 2-5 , the compression locking piece 3 is arranged in one-to-one correspondence in the receiving cavity 13. Each compression locking piece 3 is provided with a compression part 31 and an abutting part 32 connected in the first direction M, and the compression part 31 is pressed against one side of the first limiting part 14 away from the second limiting part 21 to press the first limiting part 14 towards the second limiting part 21. Specifically, the compression part 31 is pressed against one side of the first limiting part 14 in the second direction N away from the second limiting part 21, thereby improving the connection stability of the terminal assembly 2 and the housing 1.

[0034] Referring to Figure 4 and Figure 5The first limiting part 14 and the inner side wall of the shell 1 are provided with an accommodation gap 15, the pressing part 31 is arranged in the accommodation gap 15, and the thickness of the pressing part 31 in the second direction N is greater than or equal to the width of the accommodation gap 15 in the second direction N. In this way, when the pressing part 31 extends into the accommodation gap 15, the first limiting part 14 is pressed towards the second limiting part 21.

[0035] Please refer to Figure 4 and Figure 5 The thickness of the pressing part 31 in the second direction N is less than the thickness of the abutting part 32 in the second direction N. In this way, by increasing the thickness of the abutting part 32 in the second direction N, the carrying capacity of the abutting part 32 is also increased, preventing the abutting part 32 from being deformed when the sealing assembly 4 is pressed against the abutting part 32 in the first direction M.

[0036] Please refer to Figures 1-5 The sealing assembly 4 is connected to the wire end 12, and the sealing assembly 4 is sealingly connected to the terminal assembly 2 and abuts against the abutting part 32 to press the pressing and locking part 3 into the accommodation cavity 13. Specifically, the sealing assembly 4 abuts against the side of the abutting part 32 away from the pressing part 31 in the first direction M. The sealing assembly 4 includes a wire end sealing ring 41 and a sealing cover 42.

[0037] The wire end sealing ring 41 includes a body part 411 and a protruding part 412, and the protruding part 412 protrudes from one end of the body part 411 away from the pressing and locking part 3. The wire end sealing ring 41 is provided with a first through hole 413 penetrating the body part 411 and the protruding part 412 in the first direction M. The first through hole 413 is used to allow the terminal assembly 2 to pass through.

[0038] In this embodiment, the outer circumferential surface of the body part 411 is provided with a sealing ridge 414, which sealingly abuts against the inner side wall of the wire end 12. In this way, the sealing performance of the wire end sealing ring 41 can be improved.

The sealing cover 42 is provided with a connecting clamping groove 422, and the outer side of the wire end 12 is provided with a connecting protrusion 121, and the connecting clamping groove 422 and the connecting protrusion 121 are correspondingly clamped. The connection of the sealing cover 42 and the shell 1 is realized by the cooperation of the connecting clamping groove 422 and the connecting protrusion 121.

[0040] Please refer to Figure 1 and Figure 2 The mating end 11 of the shell 1 is provided with a sealing matching part 16. The inner wall of the sealing matching part 16 is used to sealingly connect with the outer wall of the mating end sealing ring of the female end connector.

[0041] Please refer to Figure 1 and Figure 2The outer side of the male end 11 is further provided with a connecting piece 17, which is used to cooperate with the connecting structure on the female end connector to fix the male end connector and the female end connector.

[0042] The terminal assembly 2 of the male end connector of the present application first passes through the second through hole 421 of the sealing cover 42, then passes through the first through hole 413 of the wire end sealing ring 41, then passes through the compression locking piece 3, and then extends into the receiving cavity 13 from the wire end 12 of the shell 1. The second limiting part 21 on the terminal assembly 2 cooperates with the first limiting part 14 on the cavity wall of the receiving cavity 13 to lock the terminal assembly 2 in the receiving cavity 13, realizing the first locking of the terminal assembly 2. Then the compression locking piece 3 is extended into the receiving cavity 13, and the compression part 31 of the compression locking piece 3 is pressed against the side of the first limiting part 14 away from the second limiting part 21 to press the first limiting part 14 towards the second limiting part 21, realizing the second locking of the terminal assembly 2. Finally, the connection clamping groove 422 on the sealing cover 42 cooperates with the connection protrusion 121 on the shell 1 to realize the connection of the sealing cover 42 and the shell 1, and the sealing ring 41 and the compression locking piece 3 are limited in the first direction M by the sealing cover 42.

[0043] In summary, in the male end connector of the present application, the first limiting part 14 is provided on the cavity wall of the receiving cavity 13 in the shell 1, which can cooperate with the second limiting part 21 on the outer wall of the terminal assembly 2 extending into the receiving cavity 13 to lock the terminal assembly 2 in the receiving cavity 13. Further, the compression locking piece 3 is provided to press the first limiting part 14 towards the second limiting part 21, realizing the improvement of connection stability and waterproof performance with relatively simple and compact structure. Furthermore, the compression locking piece 3 is pressed in the receiving cavity 13 by the sealing assembly 4 to avoid the loosening of the terminal assembly 2, meeting the requirements of vehicle waterproof function and being applicable to 10Gbps high-speed data transmission application.
