Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0035] like Figure 1-7 As shown, this utility model proposes a high-voltage connector, comprising:

[0036] The male end housing 100 and a male terminal 101 disposed within the male end housing 100; the male terminal 101 passes through the male end housing 100 and is connected to the female end housing 200 along with the male end housing 100; the female end housing 200 and a female terminal 201 disposed within the female end housing; in the connected state, the male terminal 101 is inserted into the female terminal 201; specifically, during connection, the male end housing 100 is connected to the female end housing 200, and the male terminal 101 is inserted into the female terminal 201, thus establishing electrical communication with the female terminal 201; wherein, the female terminal 201 is connected to a high-voltage shielded wire; a connecting rod 1 is rotatably disposed on the male end housing 100; in the connected state, the mounting hole 2 on the connecting rod 1 is connected to the connector 3 on the female end housing 200; a locking body 4 is disposed on the female end housing 200; in the locked state, the connecting rod 1 is engaged with the locking body 4. When it is necessary to connect the male terminal housing 100 and the female terminal housing 200, the male terminal 101 is inserted into the female terminal 201, and the male terminal housing 100 is inserted into the female terminal housing 200. By operating the connecting rod 1, the male terminal housing 100 is driven to further contact the female terminal housing 200, and after the connecting rod 1 is engaged with the locking body 4, the fixation between the male terminal housing 100 and the female terminal housing 200 is completed. When it is necessary to separate the male terminal housing 100 and the female terminal housing 200, the connecting rod 1 is operated in the reverse direction to separate the male terminal housing 100 and the female terminal housing 200. It should be noted that a conductive layer is provided on both the male terminal 101 and the female terminal 201 to further reduce the resistance between the male terminal 101 and the female terminal 201. This conductive layer is made of a highly conductive material, such as a silver-plated layer or a gold-plated layer.

[0037] The technical solution of this utility model provides a connecting rod 1 between the male end housing 100 and the female end housing 200. On the one hand, the connecting rod 1 connects to the connector 3 to achieve an initial connection between the male end housing 100 and the female end housing 200. On the other hand, by rotating the connecting rod 1 to connect with the locking body 4, the male end housing 100 and the female end housing 200 are further connected, thereby ensuring the stability between the male end housing 100 and the female end housing 200 after connection. Compared with the prior art, the technical solution of this utility model achieves multi-position connection, improving the reliability of the connection. In addition, it omits the threaded connection in the prior art, and the operation of the connecting rod 1 can achieve quick assembly and disassembly between the male end housing 100 and the female end housing 200, further reducing time costs.

[0038] like Figure 2 As shown, it also includes a first sealing ring 51, which is sleeved on the female terminal 201; in the connected state, it is placed between the male terminal housing 100 and the female terminal 201; specifically, when the male terminal housing 100 and the female terminal housing 200 are connected, the first sealing ring 51 seals the interior of the male terminal housing 100 and the female terminal 201, thereby achieving a seal between the male terminal housing 100 and the female terminal 201 and preventing foreign objects from entering between the male terminal housing 100 and the female terminal 201; in addition, a second sealing ring 52 is also provided on the male terminal housing 100. When the male terminal housing 100 is connected to the outside, the second sealing ring 52 seals the connection, improving the seal between the male terminal housing 100 and the outside.

[0039] In addition, the female end housing 200 is provided with an installation channel 6; in the connected state, one end of the male end housing 100 passes through the installation channel 6; when connecting, one end of the male end housing 100 is inserted into the installation channel 6 and moved.

[0040] like Figure 2 , 4 As shown in Figure 5, a limiting plate 71 is provided on the male end housing 100, and a pressing plate 72 is provided on the female end housing 200. In the connected state, the limiting plate 71 is placed in the mounting channel 6 and is engaged with the pressing plate 72. When the male end housing 100 and the female end housing 200 are connected, one end of the male end housing 100 moves in the mounting channel 6, and the limiting plate 71 follows the male end housing 100 into the mounting channel 6. As the limiting plate 71 moves continuously, it comes into contact with the pressing plate 72. In this utility model, the pressing plate 72 is provided with a locking block, which contacts the limiting plate 71 and achieves engagement with the limiting plate 71. Thus, the initial connection between the male end housing 100 and the female end housing 200 is completed.

[0041] like Figure 4 or Figure 5As shown, a rear cover 8 is provided at one end of the female end housing 200, and several wire holes are provided in the rear cover 8; specifically, the rear cover 8 is snapped together with the female end housing 200, and the high-voltage shielded wire passes through several wire holes and is connected to the female terminal 201; and during use, the position of the high-voltage shielded wire is restricted by the rear cover 8 to prevent it from shaking on the female end housing 200.

[0042] like Figure 6 and 7 As shown, the male end housing 100 has limit protrusions 91 on both sides, and a rotating post 92 is provided on the limit protrusions 91; the female end housing 200 has limit grooves 93 on both sides; in the connected state, the limit protrusions 91 are engaged in the limit grooves 93, and the connecting rod 1 is provided on the rotating post 92; when the female end housing 200 is connected to the male end housing 100, the limit protrusions 91 and the limit grooves 93 cooperate to make the limit grooves 93 act as a slide between the male end housing 100 and the female end housing 200, and the male end housing 100 is supported by the limit protrusions 91 to make the female end housing 100... The male end housing 100 moves within the female end housing 200. On the other hand, when the connecting rod 1 is operated, since the connecting rod 1 is connected to the rotating column 92, the male end housing 100 will drive the limiting protrusion 91 to move within the limiting groove 93 under the action of the rotating column 92, ensuring the stability of the female end housing 200's movement under the drive of the connecting rod 1. In addition, after the male end housing 100 is connected to the female end housing 200, the cooperation of the limiting protrusion 91 and the limiting groove prevents the male end housing 100 from rotating on the female end housing 200, improving the stability after installation.

[0043] like Figure 3 As shown, the connecting rod 1 is provided with an arc-shaped groove 11, and the rotating column 92 passes through the arc-shaped groove 11. When the connecting rod 1 rotates about the connector 3 as the axis, due to the existence of the arc-shaped groove 11, the arc-shaped groove 11 will slide on the rotating column 92, and during the sliding process, it will drive the male end housing 100 to move towards the female end housing 200, further increasing the connection strength between the male end housing 100 and the female end housing 200. The mounting hole 2 is provided with a base plate, and the base plate is provided with a through hole that matches the connector 3. During installation, the connector 3 passes through the through hole on the base plate to complete the connection between the connecting rod 1 and the female end housing 200. During rotation, the through hole on the base plate rotates, thereby preventing the connector 3 from disengaging from the mounting hole 2 after rotation.

[0044] like Figure 2As shown, the locking body 4 includes a fixing part 41 and a locking arm 42. The fixing part 41 is disposed on the female end housing 200; the locking arm 42 is disposed on the fixing part 41. In the connected state, the connecting rod 1 is engaged with the locking arm 42. When the connecting rod 1 rotates, the locking arm 42 limits the connecting rod 1. The locking arm 42 is provided with a locking groove 43, and the connecting rod 1 is provided with a locking block 12. In the connected state, the locking block 12 is engaged in the locking groove 43. The locking groove 43 and the locking block... The cooperation of 12 completes the fixation of the connecting rod 1; when it is necessary to separate the male end housing 100 from the female end housing 200, press the locking arm 42 to separate the locking block 12 from the locking groove 43 before operating the connecting rod 1; of course, to facilitate the operation of the locking arm 42, preferably, there is an action space 44 between the locking arm 42 and the fixing part 41; when the locking arm 42 is pressed, the locking arm 42 will move into the action space 44; and when the locking arm 42 is released, the locking arm 42 will reset under its own elasticity.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
