[0017] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0018] In order to illustrate the technical solution of the present invention, specific embodiments are provided below.

[0019] like Figures 1 - 4 As shown, a high-voltage connector according to an embodiment of the present invention includes a signal terminal 1 and a socket housing 3. In particular, it also includes a mounting member 2 for mounting the signal terminal 1, and the mounting member 2 is provided with a first cavity 21 for accommodating the signal terminal 1 and a locking structure 22 and a limiting structure 23 for locking the signal terminal 1. When the signal terminal 1 is inserted into the first cavity 21, the locking structure 22 locks the signal terminal 1, and when the signal terminal 1 is removed from the first cavity 21, the locking structure 22 releases the lock on the signal terminal 1. The limiting structure 23 engages with the signal terminal 1 to limit the movement of the signal terminal 1. The socket housing 3 is detachably connected to the mounting member 2.

[0020] When the high-voltage connector requires a signal jack, first install the signal terminal 1 into the mounting part 2. The signal terminal 1 has its own claws that clamp the limiting structure 23, and the locking structure 22 self-locks the signal terminal 1 to form a secondary lock hook. Then push the mounting part 2 in from the rear end of the socket shell 3. The mounting part 2 and the socket shell 3 are locked and positioned to complete the installation of the signal terminal 1. If the signal jack is not needed, the mounting part 2 in the socket shell 3 can be withdrawn.

[0021] In this embodiment, a locking structure 22 and a retaining structure 23 are provided on the mounting member 2 to provide a dual locking mechanism for the signal terminal 1, ensuring stable installation. The locking structure 22 and retaining structure 23 communicate with the first cavity 21, facilitating locking of the signal terminal 1. When the signal terminal 1 is removed from the mounting member 2, the locking structure 22 releases the lock on the signal terminal 1, facilitating its removal. Furthermore, the receptacle housing 3 engages the mounting member 2, enabling flexible installation and removal of the mounting member 2.

[0022] like Figures 1 - 3 As shown, in some embodiments of the present invention, the locking structure 22 includes a locking block 221 and a receiving portion 222 for accommodating the locking block 221. The receiving portion 222 is a notch provided on the mounting member 2, which extends along the outer wall of the mounting member 2 to the first cavity 21. One end of the locking block 221 is rotatably connected to the mounting member 2. When the locking block 221 is accommodated in the receiving portion 222, the locking block 221 partially extends into the first cavity 21.

[0023] In this embodiment, when the locking block 221 is received in the receiving portion 222, the lower portion of the locking block 221 is located in the recess of the signal terminal 1, locking the signal terminal 1 in the first cavity 21 and restricting the movement of the signal terminal 1. When the locking block 221 leaves the receiving portion 222, the locking of the signal terminal 1 is released.

[0024] As Figures 1 - 3 shown, in some embodiments of the present invention, the limiting structure 23 is a groove formed in the inner sidewall of the first cavity 21, a claw is provided on the signal terminal, and the groove is engaged with the claw on the signal terminal 1 to prevent the signal terminal 1 from moving forward to the front end of the mounting member 2.

[0025] As Figures 1 - 4 shown, in some embodiments of the present invention, the socket housing 3 is provided with a second cavity 31 for mounting the mounting member 2, and a convex structure is provided at the end of the mounting member 2. The socket housing 3 is provided with a clamping hole 32 engaged with the convex structure, and the clamping hole 32 is arranged above the second cavity 31 and communicated with the second cavity 31, facilitating the installation and disassembly of the mounting member 2.

[0026] As Figures 1 - 4 shown, in some embodiments of the present invention, the convex structure includes a connecting arm 24 and a convex 25. One end of the connecting arm 24 is connected to the mounting member 2, and the convex 25 is provided at the end of the connecting arm 24 away from the mounting member 2. When the convex 25 is inserted into the second cavity 31, the connecting arm 24 is deformed to facilitate the convex 25 to enter the second cavity 31. When the convex 25 enters the clamping hole 32 and is engaged with the clamping hole 32, the connecting arm 24 returns to its original shape. When removing the mounting member 2 from the socket housing 3, the convex 25 is pressed down at the clamping hole 32 and pushed out from one end of the second cavity 31.

[0027] As Figures 1 - 4 shown, in some embodiments of the present invention, a slope is provided at one end of the convex 25 near the connecting arm 24.

[0028] As Figures 1 - 4 shown, in some embodiments of the present invention, a limiting portion is provided on the outer surface of the mounting member 2, and the limiting portion is a protrusion 26. A relief groove 33 for the protrusion 26 to pass through is provided in the front section of the inner sidewall of the second cavity 31, and the surface of the protrusion 26 abuts against the bottom of the relief groove 33 to prevent the mounting member 2 from moving out from the rear section of the second cavity 31.

[0029] As Figures 1 - 3 shown, in some embodiments of the present invention, two first cavities 21 are provided on the signal mounting member 2, and the locking structure 22 and the limiting structure 23 are provided in each first cavity 21.

[0030] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. These modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention, and should all be included in the protection scope of the present invention.
