DETAILED DESCRIPTION

[0031] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all the other embodiments obtained by a person of ordinary skill in the art without creative effort belong to the scope of protection of the present application.

[0032] With reference to Figures 1-14 The new energy vehicle explosion-proof charging pile comprises a charging pile shell 1 and a charging wire 3. The charging pile shell 1 is made of thickened metal, such as aluminum alloy or stainless steel. The joints of the shell are sealed in a labyrinth manner. The labyrinth sealing is a common sealing technology in engineering, mainly used to prevent liquid, gas or dust from leaking through the joints between two components. In this case, it can be used to seal rainwater and dust. The core principle is to design a complex winding path to increase the flow resistance of the leakage medium, thereby effectively blocking the leakage channel. A series of alternating grooves, protrusions or tooth-like structures are designed at the joints, so that the leakage medium must pass through multiple turns, expansion and contraction. This winding path significantly reduces the flow energy of the medium and even completely blocks the leakage.

[0033] Meanwhile, aluminum heat dissipation fins + heat-conducting silica gel can be arranged on the charging pile shell 1 to provide overall heat dissipation by cooperation. This heat dissipation method does not produce electric sparks, indirectly improving the overall explosion-proof effect. The charging pile shell 1 is fixedly installed with a socket. One end of the charging wire 3 is fixedly installed with a plug 6. The charging wire 3 is electrically connected to the socket on the charging pile shell 1 through the plug. The plug 6 and the socket are used to facilitate the electrical installation between the charging wire 3 and the charging pile shell 1. When the charging wire 3 is pulled, the charging wire 3 and the charging pile shell 1 are easily separated, and the separation between the plug 6 and the socket does not damage the charging wire 3, so that the charging wire 3 can be reused, reducing the actual cost. Meanwhile, a rubber ring 5 can be fixedly sleeved on the outer circle of the plug 6. The rubber ring 5 can be held by the staff when installing the charging wire 3. The rubber ring 5 is made of insulating rubber, effectively preventing the socket on the charging pile shell 1 from causing electric shock due to electric leakage, improving the safety performance of the charging pile shell 1, and making the use more comfortable.
