[0047] like Figures 1 to 10As shown, the embodiment of the utility model discloses a board-end high-voltage connector, which includes a board-end high-voltage connector body 30 and a transition connector 40. The board-end high-voltage connector body 30 is suitable for connecting with the line-end high-voltage connector 50; the transition connector 40 is configured to connect the board-end high-voltage connector body 30 with the mounting plate 20, and the transition connector 40 has a first connection portion 41 suitable for connecting with the mounting plate 20, and a second connection portion 42 connected with the board-end high-voltage connector body 30.

[0048] like Figures 1 to 10 As shown, the end high-voltage connector disclosed in the embodiment of the utility model connects the board end high-voltage connector body 30 to the second connection part 42, and connects the first connection part 41 to the mounting plate 20, so that the board end high-voltage connector body 30 is connected to the mounting plate 30 through the adapter connector 40. This reduces the assembly tolerance between the circuit board 10 and the housing. In addition, it is convenient to achieve the sealing of the board end high-voltage connector.

[0049] In the embodiment of the utility model, the adapter connector 40 includes a first connection portion 41 and a second connection portion 42. Specifically, the second connection portion 42 can be integrally formed with the first connection portion 41. The second connection portion 42 can be welded to the first connection portion 41. In the embodiment of the utility model, there are no excessive restrictions on the specific way in which the second connection portion 42 is connected to the first connection portion 41. In actual applications, technicians can set it as needed.

[0050] It should be noted that the first connection portion 41 can be detachably connected to the mounting plate 20, and the second connection portion 41 can also be snapped onto the mounting plate 20. The second connection portion 42 can be sleeved on the outside of the board-end high-voltage connector body 30, or can be snapped onto the board-end high-voltage connector body 30. In the embodiment of the utility model, there are no excessive restrictions on the specific connection method between the first connection portion 41 and the mounting plate 20, and the specific connection method between the second connection portion 42 and the board-end high-voltage connector body 30. In actual applications, technicians can set them as needed.

[0051] Alternatively, if Figures 1 to 10 As shown, the second connection part 42 in the embodiment of the utility model is vertically connected to the first connection part 41, and a first through hole is provided on the adapter connector 40, and the first through hole passes through the first connection part 41 and the second connection part 42; the first through hole is sleeved on the outer wall of the board-end high-voltage connector body 30.

[0052] The adapter connector 40 in the embodiment of the utility model includes a first connection part 41 and a second connection part 42 vertically connected to the first connection part 41. A first through hole is provided on the adapter connector 41, and the first through hole passes through the first connection part 41 and the second connection part 42. Among them, the second connection part 42 is penetrated on the mounting plate 20, and at least partially exposed to the outside of the mounting plate 20. In addition, the inner wall of the second connection part 42 is sleeved on the outer wall of the board-end high-voltage connector body 30, and the second connection part 42 is clearance-matched with the board-end high-voltage connector body 30. The first connection part 41 abuts against the mounting plate 20.

[0053] In the embodiment of the utility model, the first connecting part 41 is abutted against the mounting plate 20 to limit the adapter connector 40 along the first direction A. The second connecting part 42 is sleeved on the outer wall of the board-end high-voltage connector body 30 to limit the board-end high-voltage connector body 30 in the second direction B and the third direction C through the second connecting part 42. As a result, the end face of the board-end high-voltage connector body 30 close to the mounting plate 20 is located in the second connecting part 42, and the end face of the board-end high-voltage connector body 30 close to the mounting plate 20 is protected by the second connecting part 42 to prevent bumps during transportation. In addition, the mounting plate 20 can absorb the assembly errors between the through holes of the circuit board 10 and the through holes of the mounting plate 20 along the first direction A, the second direction B and the third direction C, solve the sealing problem caused by the assembly error between the board-end high-voltage connector body 30 and the mounting plate 20, and make the sealing of the board-end high-voltage connector better.

[0054] Alternatively, if Figures 4 to 6 As shown, the board-end high-voltage connector in the embodiment of the utility model further includes a first sealing ring 60 , wherein the first sealing ring 60 is disposed between the inner wall of the first through hole and the outer wall of the board-end high-voltage connector body 30 .

[0055] like Figures 4 to 6 As shown, in the embodiment of the utility model, a first sealing ring 60 is arranged between the inner wall of the first through hole and the outer wall of the board end high voltage connector body 30. The first sealing ring 60 seals the gap between the inner wall of the first through hole and the outer wall of the board end high voltage connector body 30 to improve the sealing performance of the board end high voltage connector.

[0056] Specifically, the board-end high-voltage connector body 30 can be provided with the first sealing ring 60, that is, the board-end high-voltage connector body 30 and the first sealing ring 60 can be integrally formed. For example, the board-end high-voltage connector body 30 is made of plastic material, and the first sealing ring 60 is made of rubber material, and the plastic material and the rubber material are integrally formed by injection molding to form the first sealing ring 60 on the peripheral wall of the board-end high-voltage connector body 30. It is also possible to set a mounting groove on the peripheral wall of the board-end high-voltage connector body 30, sleeve the first sealing ring 60 in the mounting groove, and then sleeve the second connecting portion 42 on the outer wall of the board-end high-voltage connector body 30, so that the first sealing ring 60 is set between the outer wall of the board-end high-voltage connector body 30 and the inner wall of the first through hole.

[0057] Of course, the above are only individual examples of the embodiments of the present invention and are not intended to be limitations of the present invention. In actual applications, technicians can also choose a suitable method as needed to set the first sealing ring 60 between the inner wall of the second connecting portion 42 and the outer wall of the board-end high-voltage connector body 30.

[0058] It should be noted that, in the embodiment of the utility model, the gap between the outer wall of the second connecting portion 42 and the inner wall of the through hole of the mounting plate 20 is large enough, and the gap is not less than the tolerance of the circuit board 10 and the mounting plate 20 along the second direction B and the third direction C. And along the first direction A, the height of the first sealing ring 60 is lower than the height of the mounting plate 20.

[0059] In addition, the height difference between the first sealing ring 60 and the end surface of the second connecting portion 42 close to the board-end high-voltage connector body 30 is large enough, and the height difference is not less than the tolerance between the circuit board 10 and the mounting board 20 along the first direction A to prevent sealing failure.

[0060] Optionally, a first dustproof groove 32 is provided on the outer wall of the board-end high-voltage connector body 30, and the second connecting part 42 is inserted into the first dustproof groove 32; or, a second dustproof groove 34 is provided at the end of the board-end high-voltage connector body 30 close to the second connecting part 42, and a snap-on part 421 is provided on the inner wall of the second connecting part 42, and the snap-on part 421 is inserted into the second dustproof groove 34.

[0061] like Figure 2 and Figure 4 As shown, the outer wall of the board-end high-voltage connector body 30 is provided with a first dustproof groove 31, and the second connection part 42 is inserted into the first dustproof groove 32 near the end of the board-end high-voltage connector body 30 to further improve the sealing of the board-end high-voltage connector. In addition, during the after-sales maintenance, disassembly, transportation, and assembly process, foreign matter such as dust and liquid can be accumulated through the first dustproof groove 32 to prevent foreign matter such as liquid and dust from entering the connector, causing problems such as contamination and short circuit of the board-end high-voltage connector.

[0062] It should be noted that in the embodiment of the utility model, the height difference between the end of the second connecting part 42 close to the board-end high-voltage connector body 30 and the bottom wall of the first dustproof groove 32 is large enough, and the height difference is not less than the tolerance of the circuit board 10 and the mounting board 20 along the first direction A, so as to prevent the second connecting part 42 and the first dustproof groove 32 from interfering with each other during the assembly process, resulting in the adapter connector 40 not being assembled in place.

[0063] like Figure 6 As shown, a second dustproof groove 34 can be set at the end of the board-end high-voltage connector body 30 near the adapter connector 40, and a clamping portion 421 can be set on the inner wall of the second connecting portion 42, and the clamping portion 421 can be inserted into the second dustproof groove 32 to seal the second connecting portion 42 and the board-end high-voltage connector body 30 through the clamping portion 421 and the second dustproof groove 32, thereby further improving the sealing of the board-end high-voltage connector.

[0064] Alternatively, if Fig.10 As shown, the board-end high-voltage connector further includes a dust cover 90 , which is detachably connected to the first connecting portion 41 .

[0065] When the line-end high-voltage connector 50 is not connected to the board-end high-voltage connector body 30, the dust cover 90 is connected to the first connection portion 41 through the drawstring 91. During the transportation and maintenance of the board-end high-voltage connector, the dust cover 90 can be covered on the board-end high-voltage connector body 30 to prevent dust and liquids such as water from entering the board-end high-voltage connector body 30. When the line-end high-voltage connector 50 needs to be connected to the board-end high-voltage connector body 30, the dust cover 90 is removed.

[0067] It should be noted that the connector assembly disclosed in the embodiment of the utility model can be connected to the box of the battery pack of an electric vehicle, so as to connect the battery in the battery pack to an external power source and electrical devices through the connector assembly. Of course, the above are only individual examples of the application scenarios of the connector assembly and are not intended to limit the application scenarios of the connector assembly. In actual applications, technicians can install the connector assembly on any charged device as needed.

[0068] like Figures 1 to 10As shown, in the embodiment of the utility model, the line-end high-voltage connector 50 is inserted into the adapter connector 40, and at least partially extends into the board-end high-voltage connector body 30, and is connected to the board-end high-voltage connector body 30. Therefore, the connection between the board-end high-voltage connector body 30 and the line-end high-voltage connector 50 can be limited by the adapter connector 40, thereby reducing the assembly tolerance of the connector assembly and improving the assembly efficiency of the connector assembly. Furthermore, it is also convenient to seal the connector assembly.

[0069] Alternatively, if Figures 4 to 6 As shown, the line-end high-voltage connector 50 disclosed in the embodiment of the utility model includes a line-end high-voltage connector body 52 and a third connection portion 53 connected to the outer wall of the line-end high-voltage connector body 52, wherein at least a portion of the line-end high-voltage connector body 52 is passed through the adapter connector 40 and connected to the board-end high-voltage connector body 30; the third connection portion 53 abuts against the first connection portion 41.

In addition, the third connecting portion 53 connected to the outer wall of the line-end high-voltage connector body 52 is abutted against the first connecting portion 41, so as to support the line-end high-voltage connector body 52 through the first connecting portion 41.

[0071] It should be noted that if Figures 4 to 6 As shown, the line end high voltage connector 50 in the embodiment of the utility model further includes a wiring harness 51, a tail cover 55, a shielding ring 56, a fourth sealing ring 57, a housing and other structures.

In actual applications, technicians can also select a suitable line end high voltage connector 50 according to needs.

[0072] Alternatively, if Figures 4 to 6 As shown, the connector assembly in the embodiment of the utility model further includes a second sealing ring 80 , and the second sealing ring 80 is disposed between the third connecting portion 53 and the first connecting portion 41 .

[0073] like Figures 4 to 6 As shown, a second sealing ring 80 is provided between the third connecting portion 53 and the first connecting portion 41 to seal the gap between the third connecting portion 53 and the first connecting portion 41 through the second sealing ring 80, thereby further improving the sealing performance of the connector assembly.

The mounting plate 20 is provided with a second through hole, and the second connecting portion 42 is passed through the second through hole and sleeved on the outer wall of the board-end high-voltage connector body 30.

[0076] Through the above arrangement, the end face of the board-end high-voltage connector body 30 can be located in the second connection part 42, and the end face of the board-end high-voltage connector body 30 close to the mounting plate 20 can be protected by the second connection part 42 to prevent bumps during transportation. Furthermore, the mounting plate 20 can absorb the assembly errors between the through holes of the circuit board 10 and the through holes of the mounting plate 20 along the first direction A, the second direction B, and the third direction C, thereby solving the sealing problem caused by the assembly error between the board-end high-voltage connector body 30 and the mounting plate 20, and making the sealing of the electronic equipment more tight.

[0077] Alternatively, if Figures 1 to 10 As shown, the electronic device disclosed in the embodiment of the utility model also includes a circuit board 10, which is arranged on the side of the board-end high-voltage connector body 30 away from the mounting board 20, and the board-end high-voltage connector body 30 has a first connecting terminal 31, and one end of the first connecting terminal 31 is plugged into the circuit board 10; the line-end high-voltage connector body 52 is arranged on the side of the first connecting portion 41 away from the mounting board 20, and the line-end high-voltage connector body 52 has a second connecting terminal 54, and the second connecting terminal 54 at least partially extends into the board-end high-voltage connector body 30 and is plugged into the other end of the first connecting terminal 31.
