Connecting structure of charging interface

Abstract

The invention discloses a connecting structure of a charging interface, which is simple in structure and can reduce the manufacturing cost. The connecting structure comprises a plug and a socket, wherein the socket comprises a socket shell and a socket body installing seat which is arranged in the socket shell, and a connecting end of the socket shell is provided with a circular socket barrel; the plug comprises a plug body installing seat and a plug shell which is connecting with the plug body installing seat, a pulling preventing cover is movably sheathed on the plug shell and the plug body installing seat, the inner wall of the pulling preventing cover is provided with circumferential inner connecting threads and a limiting boss in sequence along the pulling-out direction, a circumferential in-place boss is arranged on the plug body installing seat, and the limiting boss and the inner connecting threads are positioned at two sides of the placing-in boss; and outer connecting threads which are matched with the inner threads are arranged on the outer wall of the circular socket barrel. By the mutual matching of the pulling preventing cover and the circular socket barrel of the socket shell, the connecting structure can achieve the purpose that the pulling by mistake is prevented, and eliminates potential safety hazards.

Description

technical field [0001] The invention relates to a charging interface, in particular to a connection structure of the charging interface. Background technique [0002] The connection structure of some current charging interfaces, that is, the connection structure of the socket and the plug, has not been equipped with an anti-unplugging mechanism to prevent accidental extraction, which has a large safety hazard, especially for the charging interface used for high-voltage AC as a charging source. Danger. The main reason for not adding an anti-tear mechanism is that the existing anti-tear structures are relatively complicated, which makes the structure of the entire charging interface more complicated and the manufacturing cost is higher. In addition, the plugs of some current charging interfaces have poor sealing performance and are prone to water ingress; moreover, there is no obvious guide mechanism for indicating the insertion position on the socket and the socket, which in...

Danger

The main reason for not installing an anti-tear mechanism is that the existing anti-tear structures are relatively complicated, which makes the structure of the entire charging interface more complicated and the manufacturing cost is higher

In addition, some of the current charging interfaces have poor plug sealing performance and are prone to water ingress; moreover, there is no obvious guide mechanism for indicating the plugging position on the socket and the socket, which increases the difficulty of plugging.
