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

[0041] like Figure 1-12 As shown, this utility model proposes a two-core high-voltage connector, comprising:

[0042] The device includes a male terminal 200 and a female terminal 100, with a latch 300 on the male terminal 200. In the connected state, the male terminal 200 is inserted into the female terminal 100, and the latch 300 connects the male terminal 200 to the female terminal 100. In actual use, the connecting component inside the female terminal 100 needs to connect a wire 6, ensuring continuity between the wire 6 of the male terminal 200 and the wire 6 of the female terminal 100 after connection with the male terminal 200. Furthermore, the latch 300 is located on the male terminal 200 and can slide on it. Specifically, the female terminal... A snap-fit ​​protrusion 102 is provided on end 100. In the connected state, the snap fastener 300 is connected to the snap-fit ​​protrusion 102. The connection between the female end 100 and the male end 200 is completed by the cooperation of the snap fastener 300 and the snap-fit ​​protrusion 102. When it is necessary to separate the male end 200 from the female end 100, press the snap fastener 300 by hand and push the snap fastener 300 on the male end 200 during the pressing process. After the snap fastener 300 separates from the snap-fit ​​protrusion 102, the male end 200 is separated from the female end 100, and the disassembly operation is completed.

[0043] The male terminal 200 includes a housing 1, a dustproof body 2, a terminal group, and a sealing group 4. The sealing group 4 is disposed inside the housing 1 and on the outer surface of the dustproof body 2. The terminal group is disposed inside the dustproof body 2, and the wire 6 passes through the sealing group 4 and the dustproof body 2 in sequence before being connected to the terminal group. A latch 300 is disposed on the housing 1. In the connected state, the sealing group 4 is inserted into the female terminal 100, and the female terminal 100 is positioned between the housing 1 and the sealing group 4. Figure 2 As shown, the outer casing 1 includes an inner layer 11 and an outer layer 12, with a dustproof body 2 disposed in the inner layer 11. When the male terminal 200 is connected to the female terminal 100, the female terminal 100 is inserted between the inner layer 11 and the outer layer 12, and the sealing assembly 4 seals the connection between the female terminal 100 and the inner layer 11, ensuring that the connection between the female terminal 100 and the terminal group is sealed. At the same time, the dustproof body 2 is disposed inside the inner layer 11, further protecting the terminal group.

[0044] The technical solution of this utility model achieves the connection between the wires 6 through the cooperation of the male terminal 200 and the female terminal 100; after the male terminal 200 and the female terminal 100 are connected, the male terminal 200 is fixed to the female terminal 100 by snapping the male terminal 200 with the female terminal 100; when it is necessary to disassemble the male terminal 200 and the female terminal 100, the snapping 300 is operated to separate the snapping 300 from the female terminal 100 before the female terminal 100 and the male terminal 200 are disassembled; in addition, a dustproof body 2 and a sealing group 4 are provided inside the outer shell 1 of the male terminal 200, which can protect the terminal group, avoid leakage during use, and improve the sealing performance of the male terminal 200; compared with the prior art, the technical solution of this utility model has a reasonable structure and can improve the disassembly and assembly efficiency of the male terminal 200 and the female terminal 100 while ensuring sealing performance.

[0045] Of course, for better use and to avoid external interference with the terminal group during use, a shielding shell 51 is preferably provided. This shielding shell 51 is fitted onto the dustproof body 2, and the sealing assembly 4 is located on the outer surface of the shielding shell 51. On the one hand, the shielding shell 51 seals the dustproof body 2; on the other hand, it reduces electromagnetic interference to the interior of the shielding shell 51. Figure 10 As shown, a snap-fit ​​part 52 is provided on the shielding shell 51. In the connected state, the snap-fit ​​part 52 snaps into the dustproof body 2. Specifically, a groove is provided on the dustproof body 2. When the shielding shell 51 is placed on the dustproof body 2, the snap-fit ​​part 52 is placed in the groove, so that the shielding shell 51 and the dustproof body 2 are snapped together, thereby preventing the shielding shell 51 from moving on the dustproof body 2.

[0046] like Figure 2 , 4 As shown in Figures 10 and 11, the dustproof body 2 includes a first mounting cavity 21 and a second mounting cavity 22; the terminal group includes a first connecting group 31 and a second connecting group 32; the first connecting group 31 is disposed in the first mounting cavity 21; the second connecting group 32 is disposed in the second mounting cavity 22; specifically, the first connecting group 31 and the second connecting group 32 are respectively fixed in the first mounting cavity 21 and the second mounting cavity 22; at the same time, a guide groove 23 is provided between the first mounting cavity 21 and the second mounting cavity 22; the guide plate 33 in the terminal group passes through the guide groove 23; in the installed state, the guide plate 33 is inserted into the positioning hole 101 of the female end 100; as shown in Figures 10 and 11. Figure 7 and Figure 11 As shown, the guide plate 33 includes two guide posts, and the female end 100 includes two positioning holes 101. When connecting the female end 100 and the male end 200, the cooperation of the two guide posts and the two positioning holes 101 can ensure the accuracy of the installation position of the male end 200 and the female end 100.

[0047] like Figure 12As shown, the first connection group 31 includes a connection frame 311 and a connection card 312 disposed within the connection frame 311. The connection frame 311 is fixed inside the dustproof body 2. Elastic clips 313 are provided on both sides of the connection frame 311. When the connection card 312 is placed inside the connection frame 311, the elastic clips 313 contact the connection card 312. The wire 6 is clipped onto the connection card 312. After the connection card 312 is connected to the connection frame 311, the elastic clips 313 contact the connection card 312, increasing the contact area between the connection card 312 and the connection frame 311 while reducing the contact resistance. Additionally... The connector 312 has a contact point 314 disposed opposite to each other. Specifically, the connector 312 is a connecting piece disposed opposite to each other, and the contact point 314 is formed after the connecting piece is bent. When the connecting part of the female end 100 is inserted into the connecting piece disposed opposite to each other, it contacts the contact point 314. When the connecting part of the female end 100 is separated from the connecting piece, if there is an oxide layer on the connecting part, the oxide layer can be removed by sliding friction between the contact point 314 and the connecting part. In addition, the connector 312 can be replaced according to different needs to adapt to different voltages or currents.

[0048] It should be noted that the structure of the second connecting group 32 is the same as that of the first connecting group 31, and this utility model will not further limit it in order to save space.

[0049] like Figure 2 and 4 As shown, the sealing assembly 4 includes a first end cap 41 and a second end cap 42. The first end cap 41 is fitted onto one end of the inner layer 11, and the second end cap 42 is fitted onto the other end of the inner layer 11. A first sealing ring 43 is fitted onto the outer surface of the inner layer 11 and is disposed adjacent to the first end cap 41. A second sealing ring 44 is disposed at the other end of the inner layer 11 and is fitted onto the wire 6. Through the cooperation of the first end cap 41 and the second end cap 42, the inner layer 11 is sealed, thereby making the dustproof body 2 located within the space formed by the first end cap 41, the inner layer 11, and the second end cap 42. Within the sealed space, the sealing effect on the dustproof body 2 and the terminal group is improved; in addition, the first sealing ring 43 is placed on the inner layer 11 and between the inner layer 11 and the female end 100, which improves the sealing effect between the inner layer 11 and the female end 100; the second sealing ring 44 is placed inside the second end cover 42, ensuring the sealing performance of the second end cover 42; in this utility model, the first sealing ring 43 and the second sealing ring 44 are preferably made of fluororubber; so that the temperature resistance range of the first sealing ring 43 and the second sealing ring 44 is between -40℃ and 200℃.

[0050] It should be noted that the outer shell 1 in this utility model is made of high-strength composite material PA66, which reduces the overall weight without affecting the strength.

[0051] 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.
