[0025] like Figures 1 to 4As shown, a specific embodiment of the utility model provides a high-voltage connector with a protective structure, including a socket 1 and a plug 2, a protective cover 7 is arranged on the outside of the socket 1, a protective cover 9 is arranged on the outside of the plug 2, a plurality of heat sinks 14 are arranged on the outside of the protective cover 7 and the protective cover 9, a liquid detection sensor 15 is arranged inside the plug 2, and after the liquid detection sensor 15 contacts with the liquid, a closed loop is formed inside to transmit the information of the detected liquid to the controller to cut off the power switch, a protective wire sleeve 17 is arranged at the lower end of the plug 2, the protective wire sleeve 17 is arranged on the outside of the high-voltage wire 19, and the upper end of the protective wire sleeve 17 is arranged at the bottom of the plug 2.
[0026] Specifically, Figure 1 and Figure 4 As shown, a second sealing gasket 12 is provided at one end of the protective cover 7, and the second sealing gasket 12 is provided between the socket 1 and the protective cover 7, and the socket 1 and the protective cover 7 are fixedly connected by screws.
[0027] By adopting the above technical solution, the socket 1 and the protective cover 7 are connected together by adding a second sealing gasket 12 in the middle and then fixing them together by screws, thereby enhancing the sealing performance and preventing liquid from penetrating.
[0028] Specifically, Figure 2 and Figure 4 As shown, a buckle 5 is provided at one end of the socket 1 , and a clamping hole 6 is provided inside the plug 2 . After the plug 2 and the socket 1 are plugged into place, one end of the buckle 5 is clamped into the inside of the clamping hole 6 .
[0029] By adopting the above technical solution, when the socket 1 and the plug 2 are plugged into place, the buckle 5 is inserted into the inside of the card hole 6 to prevent the socket 1 and the plug 2 from being disengaged after being plugged in, and at the same time verify whether the socket 1 and the plug 2 are plugged in place. If the socket 1 and the plug 2 are not plugged in place or are loose, poor contact is likely to occur, resulting in the problem of connector burning.
[0030] Specifically, Figure 2 and Figure 4 As shown, the size of the plug 2 is adapted to the inner cavity 8 , and the inner cavity 8 is arranged inside the protective cover 7 . When the plug 2 is plugged into the socket 1 , it fits in with the inner cavity 8 , and one end of the plug 2 fits in with the protective cover 9 .
[0031] By adopting the above technical solution, after the protective cover 7 is fixedly connected to the socket 1, the plug 2 and the socket 1 are plugged into place, and then the protective cover 9 is connected to the protective cover 7. The inner sides of the protective cover 9 and the protective cover 7 are wrapped around the outer sides of the socket 1 and the plug 2 after plugging. The heat generated by the socket 1 and the plug 2 can be better transferred to the protective cover 7 and the protective cover 9, and quickly dissipated through the heat sink 14.
[0032] Specifically, Figure 1 and Figure 2As shown, one end of the protective cover 7 and the protective cap 9 are both provided with a flange 10 , a threaded hole is provided inside the flange 10 , the flanges 10 are connected by screws, and a first sealing gasket 11 is provided between the flanges 10 .
[0033] By adopting the above technical solution, the convex edges 10 at one end of the protective cover 7 and the protective cover 9 are aligned, a first sealing gasket 11 is laid in the middle, and the aligned convex edges 10 are fixedly connected by screws. The first sealing gasket 11 seals the gap between the convex edges 10 after the connection to prevent liquid from seeping in. By providing the convex edge 10, the contact area of the connection is increased and the protective cover 7 and the protective cover 9 are conveniently aligned and connected together.
[0034] Specifically, Figure 1 As shown, the protective cover 7 and the protective cover 9 are cast from a metal material with high hardness, strong electromagnetic shielding capability and good heat dissipation effect, and a grounding wire 13 is provided on one side of the protective cover 9.
[0035] By adopting the above technical scheme, the hardness of the protective cover 7 and the protective cover 9 is relatively high, and the internal connector can be protected. The connector will be slightly deformed due to high temperature, and the sealing effect will be reduced. The protective cover 7 and the protective cover 9 can better prevent liquid from penetrating, and can also shield dust and have strong electromagnetic shielding ability. A grounding wire 13 is connected to the outside, which can block the electromagnetic radiation generated by the connector from being dissipated and affecting the electronic components used in conjunction. The heat dissipation effect is good, and the heat generated by the connector can be transferred to the protective cover 7 and the protective cover 9 and quickly dissipated, so that the connector can remain stable for a long time during use, thereby increasing its service life.
[0036] Specifically, Figure 2 and Figure 4 As shown, a card slot 16 is provided at the lower end of the protective hood 7 and the protective cover 9, and a through hole is opened at the bottom of the card slot 16. The size of the through hole is adapted to the protective wire sleeve 17. The upper part of the protective wire sleeve 17 is arranged inside the card slot 16 and fits with the through hole, and a sealing ring is provided on the side wall of the through hole.
[0037] By adopting the above technical solution and arranging a sealing ring on the side wall of the through hole, the contact part of the protective wire sleeve 17 penetrating from the inside of the connected protective cover 7 and the protective cap 9 is kept sealed to prevent liquid from penetrating.
[0038] Specifically, Figure 2 and Figure 3 As shown, the protective wire sleeve 17 and the insulating layer of the high-voltage wire 19 are integrally formed, a support spring 18 is arranged inside the protective wire sleeve 17, a pin 4 is arranged at one end of the high-voltage wire 19, the size of the pin 4 is adapted to the needle seat 3, the needle seat 3 is arranged inside the socket 1, and a power wire is arranged at one end of the needle seat 3.
[0039] By adopting the above technical solution, the protective wire sleeve 17 and the insulating layer of the high-voltage wire 19 are integrally formed and arranged at the bottom of the plug 2. A support spring 18 is arranged inside the protective wire sleeve 17 and is integrally formed to avoid the risk of the insulating layer at the connection point between the high-voltage wire 19 and the bottom of the plug 2 being worn and broken due to shaking, resulting in a short circuit. The support spring 18 can provide better supporting and elastic effects, better protect the insulating layer at the connection point, and increase the service life.
