The existing high-voltage interfaces need to be assembled with copper nose locking screws, but the locking screw assembly efficiency is slow and it is easy to miss screws. During the assembly process, tools may directly contact live screws, which is not safe. Moreover, after the cable is pulled out, foreign matter, dust, etc. can easily enter the terminal, affecting the conductive performance and cannot be recycled many times.

[0037] Therefore, this application proposes a new high-voltage interface quick-plug module, such as Figure 1-Figure 10 As shown, it includes a high-voltage interface module 1, a male pin 2 and a terminal 3 that are quickly connected in the high-voltage interface module 1; the terminal 3 includes a terminal body 31 and an end cover 32 arranged on the terminal body 31; the end cover 32 is provided with a plug-in port 321, and the male pin 2 is plugged into the terminal body 31 from the plug-in port 321 to realize the quick plug-in connection between the male pin 2 and the terminal 3; the terminal body 31 is provided with a protective mechanism 4 that has a telescopic displacement toward the plug-in port 321.

[0038] In this embodiment, as a specific solution, the inner wall of one end of the terminal body 31 where the end cover 32 is provided is provided with a contact grid 5, and when the male pin 2 and the wiring terminal 3 are mated, the outer wall of the male pin 2 is in contact with the contact grid 5 for conduction.

[0039] In this embodiment, as a specific solution, the terminal body 31 is divided into three sections as a whole, namely a front section, a middle section and a tail section. The contact grid 5 is located in the front section, and the end cover 32 covers the outside of the front section. The outer wall diameter of the end cover 32 is consistent with that of the middle section, so that after the end cover 32 covers the outer walls of the front section and the middle section, a flat structure is formed.

[0040] In this embodiment, as a preferred solution, the end cover 32 further has a barb-shaped structure 322 , and the barb-shaped structure 322 hooks the inner wall of the front section of the terminal body 31 and the inner wall of the contact grid 5 .

[0041] In this embodiment, as a preferred solution, the end cover 32 and the terminal body 31 are provided with an end cover locking mechanism 6; the specific end cover locking mechanism 6 includes an end cover protrusion 61 arranged on the inner wall of the end cover 32, and a locking groove 62 arranged on the outer wall of the terminal body 31, and when the end cover 32 is covered on the terminal body 31, the end cover protrusion 61 cooperates with the locking groove 62.

[0042] In this embodiment, as a specific solution, the high voltage interface module 1 is provided with a detachable locking mechanism 7 , and the detachable locking mechanism 7 is used to lock the wiring terminal 3 .

[0043] In this embodiment, as a specific solution, the detachable locking mechanism 7 includes a locking body 71 and an elastic element 72, the locking body 71 is provided with a locking hole 711, the outer periphery of the terminal body 31 is provided with a card groove 311, the card groove 311 is located in the locking hole 711, and the locking body 71 has a displacement perpendicular to the axial direction of the terminal body 31 under the action of the elastic element 72.

[0044] In this embodiment, as a more specific solution, the locking body 71 is inserted from the outer wall of the high-voltage interface module 1 into the interior, and is perpendicular to the axial direction of the terminal body 31. The diameter of the locking hole 711 is slightly larger than the diameter of the outer circumference of the terminal body 31. The elastic element 72 is two reset compression springs. The locking body 71 is assembled into the high-voltage interface module 1 together with the elastic element 72. The locking body 71 is pressed into the interior of the high-voltage interface module 1 so that the slot 311 of the terminal body 31 can be aligned with the locking hole 711, and then the locking body 71 is released. Under the action of the elastic element 72, the locking body 71 bounces toward the outside of the high-voltage interface module 1, so that the locking hole 711 locks the terminal body 31 from the slot 311.

[0045] In this embodiment, as a specific solution, an elastic limiting boss 712 is provided on the lock body 71, and the high-voltage interface module 1 is provided with an unlocking channel 11, and the unlocking channel 11 is aligned with the elastic limiting boss 712; when the lock body 71 needs to be taken out, a tool is used to pry the elastic limiting boss 712 from the unlocking channel 11, and then the lock body 71 is taken out.

[0046] In this embodiment, as a specific solution, the protection mechanism 4 includes a protection cover 41 and an elastic element 42 . The protection cover 41 has a telescopic displacement toward the plug-in port 321 under the action of the elastic element 42 .

[0047] In this embodiment, as a more specific solution, a cavity for accommodating a protective cover 41 is provided in the middle section of the terminal body 31. When the male pin 2 is mated with the terminal block 3, the male pin 2 presses the protective cover 41 into the cavity in the middle section of the terminal body 31. When the terminal block 3 and the male pin 2 are released, under the action of the elastic element 42, the protective cover 41 rebounds toward the mouth of the end cover 32, covering the mouth of the end cover 32, thereby preventing foreign matter, dust, etc. from falling from the mouth of the end cover 32 into the terminal body 31, thereby playing a protective role.

[0048] In this embodiment, as a more specific solution, the end of the protective cover 41 away from the end cover has a circumferential expansion displacement; specifically, a plurality of grooves 411 are provided at the end of the protective cover 41 away from the end cover, and the groove 411 structure enables the end to have a buffer space for inward contraction and outward expansion in the circumferential direction.

[0049] In this embodiment, as a more specific solution, an anti-slip mechanism 8 is provided inside the terminal body 31 and between the protective cover 41; the anti-slip mechanism 8 includes a boss 81 arranged on the inner wall of the terminal body 31, and a limiting hook 82 on the outer wall of the end of the protective cover 41 away from the end cover; when the male pin 2 is matched with the terminal 3, the protective cover 41 is pressed into the cavity in the middle section of the terminal body 31, and the end with the slot 411 naturally bounces outward, so that the protective cover 41 is stable in the cavity without shaking or displacement; when the male pin 2 is released from the terminal 3, the protective cover 41 rebounds toward the mouth of the end cover 32, and the limiting hook 82 hooks the boss 81 when it rebounds into place, which can prevent the protective cover 41 from falling from the mouth of the end cover 32.

[0051] During assembly, the male pin 2 is inserted from one end of the high-voltage interface module 1, the locking body 71 together with the elastic element 72 is inserted from the side of the high-voltage interface module 1, and the cable 9 is inserted into the end of the terminal 3 away from the end cover 32. The end of the terminal 3 equipped with the end cover 32 is quickly inserted from the other end of the high-voltage interface module 1 to mate with the male pin 2 (when the terminal 3 is plugged into the high-voltage interface module 1, the locking body 71 is pressed into the high-voltage interface module 1 so that the locking hole 711 can allow the terminal body 31 to pass smoothly. When the card slot 311 is aligned with the locking hole 711, that is, when it is plugged in place, the locking body 71 is released. Under the rebound effect of the elastic element 72, the locking hole 711 is locked. 11 locks the terminal 3 from the slot 311), at this time, the protective cover 41 is pushed against the terminal body 31 by the male pin 2; when the male pin 2 and the terminal 3 need to be separated, the elastic limiting boss 712 is pried from the unlocking channel 11 with a tool, and the lock body 71 is pressed again after prying, so that the terminal 3 can be smoothly pulled out from the locking hole 711, and the protective cover 41 rebounds toward the plug interface 321 of the end cover 32 under the action of the elastic element 42, covering the plug interface 321, so that foreign matter, dust, etc. will not fall into the terminal body 31 from the plug interface 321, and at the same time, the limiting barb 82 hooks the boss 81, so that the protective cover 41 will not fall from the plug interface 321.
