Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of connectors, in particular to a new energy vehicle connector. BACKGROUND

[0002] New energy vehicles use connectors to transmit signals and electrical energy. During maintenance, some connectors are disconnected to ensure safety. To facilitate the disconnection of the male and female heads of the connector, some connectors on the market are provided with a hook between the male and female heads to facilitate disconnection. The male and female heads can be separated after the hook is loosened.

[0003] For example, a heavy load connector disclosed in Chinese patent application No. CN201820998420 is disclosed. The outer side wall of the first mounting shell is provided with a hook, and the outer side wall of the second mounting shell is provided with a clamping column. The hook can be clamped on the clamping column by rotating the hook, so that the first mounting shell and the second mounting shell are fixed to each other. The outer side wall of the first mounting shell is fixedly provided with a mounting block, and the side wall away from the first mounting shell is provided with a rotating shaft. The hook is connected with the rotating shaft and can rotate around the axis of the rotating shaft. This design uses a hook for connection. However, in practice, it is found that the hook and the rotating shaft will be loose after being disassembled and assembled for many times, which makes the connector connection loose.

[0004] For another example, a new heavy load connector module disclosed in Chinese patent application No. CN201520355468.2 includes a one-side-opened hexahedral upper shell and a lower shell covering the opening of the upper shell. A protrusion is arranged on the side of the upper shell, and a clamping hook corresponding to the protrusion is arranged on the side of the lower shell. The upper shell and the lower shell are connected by clamping the protrusion with the clamping hook. Similarly, the clamping hook and the clamping protrusion will be loose after being disassembled and assembled for many times, which makes the connector connection loose. SUMMARY

[0051] The first housing 110, the first insulation module 220, the second housing 310 and the second insulation module 330 are made of injection molding process. The first terminal module 230 and the second terminal module 340 are made of copper alloy or copper, and the first terminal module 230 and the second terminal module 340 can conduct electricity.

A first slit 232 is longitudinally arranged on the first plug-in cylinder 231. A first wire clamping piece 233 is formed at the tail of the first plug-in cylinder 231, and a first mounting piece 234 is formed by tearing in the middle of the first plug-in cylinder 231. A second slit 236 is longitudinally arranged on the first mounting cylinder 235, and the cylinder walls on both sides of the second slit 236 are interlocked by first meshing teeth 237. A first mounting hole 238 is provided at the tail of the first mounting cylinder 235. A first locking piece 239 is formed by tearing in the head of the first mounting cylinder 235. The first wire clamping piece 233 is riveted onto the first wire core. The first plug-in cylinder 231 is inserted into the first mounting cylinder 235, and the first mounting piece 234 protrudes from the first mounting hole 238.

The first wire core is inserted into the first connector sleeve 231. The first slit 232 allows the first connector sleeve 231 to be slightly expanded, and the first wire core is riveted together by the first pressure plate 233. When the first connector sleeve 231 is inserted into the first mounting sleeve 235, the first mounting plate 234 passes through the first mounting hole 238, and the first mounting hole 238 bends and presses against the outer wall of the first mounting sleeve 235, thus fixing the first connector sleeve 231 inside the first mounting sleeve 235. The sleeve walls on both sides of the second slit 236 of the first mounting sleeve 235 interlock with each other, so that the first mounting sleeve 235 will not be stretched open when the first connector sleeve 231 is inserted into it. Therefore, the assembly between the first connector sleeve 231 and the first mounting sleeve 235 is very firm and simple. The first locking piece 239 is elastic. The first terminal module hole 201 has a larger central size and smaller ends. After the first terminal module 230 is inserted into the first terminal module hole 201, it is firmly fixed inside the hole by the first locking piece 239 and will not loosen. When the first terminal module 230 is inserted into the first terminal module hole 201, it is pressed more tightly by the hole wall as the insertion depth increases, allowing the first wire core to be pressed more firmly by the first connector tube 231, resulting in better contact quality. The walls on both sides of the second slit 236 on the first mounting tube 235 interlock, facilitating the first mounting tube 235 to wrap around the first connector tube 231.

The first vapor chamber 130 and the second vapor chamber 320 are thin-walled vapor chambers. The first housing 110 and the first vapor chamber 130 are combined together by using an injection molding process. When the first housing 110 and the first vapor chamber 130 are formed, the vapor chamber and the first housing 110 can be first injection molded together, then a cooling medium is injected into the first vapor chamber 130, and then the first vapor chamber 130 is welded and sealed. Of course, the first vapor chamber 130 can also be directly injection molded with the first housing 110 as a whole. The heat absorbing area of the first vapor chamber 130 absorbs the heat of the first insulating base 210 and the second insulating base 220, and then the first heat radiating fin 131 on the heat radiating area radiates the heat. This design can improve the heat dissipation capacity of the male head 10. The second housing 310 and the second vapor chamber 320 are combined together by using an injection molding process. When the second housing 310 and the second vapor chamber 320 are formed, the vapor chamber and the second housing 310 can be first injection molded together, then a cooling medium is injected into the second vapor chamber 320, and then the second vapor chamber 320 is welded and sealed. Of course, the second vapor chamber 320 can also be directly injection molded with the second housing 310 as a whole. The heat absorbing area of the second vapor chamber 320 absorbs the heat on the third insulating base 331, and then the second heat radiating fin 321 on the heat radiating area radiates the heat.

The first uniform temperature plate 130 is in a bent shape, so that the heat absorption area of the first uniform temperature plate 130 can be in full contact with the first insulating base 210 and the second insulating base 220, and meanwhile, the heat dissipation area of the first uniform temperature plate 130 can be conveniently extended out of the first shell 110 for heat dissipation. This kind of design is more conducive to the internal structural layout of the connector. The heat dissipation area of the first uniform temperature plate 130 is arranged on the support 116 in an overhanging manner, which is helpful to increase the heat dissipation area and enable the heat dissipation area to be welded with the first heat sink fins on both sides, so as to improve the heat dissipation efficiency.

The first cable is inserted from the wire inlet 126, and as the wire inlet shell 121 is screwed on the wire inlet 126 by threads, the metal ring 122 extrudes the first sealing ring 125, so that the first sealing ring 125 can tightly wrap the cable. This kind of design structure is simple and has good waterproof capability, and water cannot enter the interior of the connector through the wire inlet 126.

When the locking column 311 is inserted into the locking hole 414, the elastic protrusion 415 can press the locking column 311 at the end of the locking hole 414, which can limit the locking column 311 and ensure that the locking column 311 does not displace in the locking hole 414, and the firmness is better.

[0063] The rotating shaft 119 can rotate on the rotating shaft hole 416. The rotating shaft 119 is inserted into the rotating shaft hole 416 of the locking frame 410, and the second limiting part 117 on the rotating shaft 119 is pressed on the hole opening of the rotating shaft hole 416, which can ensure that the rotating shaft 119 and the rotating shaft hole 416 are not loose, and improve the assembly firmness between the locking frame 410 and the rotating shaft 119.
