Explosion-proof outdoor automobile charging pile

Abstract

The invention relates to the technical field of automobile charging piles. The invention discloses an explosion-proof outdoor automobile charging pile that comprises a pile body, a box door, an electrical module, a wire connector, a cable, a lug plate and a fastening screw; a through groove is formed in the pile body, a sleeve is arranged on the portion, located on the outer side of the fasteningscrew, of the top face of the pile body; a groove is formed in the bottom face of the through groove of the wire connector, a spring is fixedly installed on the bottom face of the groove, and the topend of the spring is fixedly connected with the bottom face of the lug plate. The invention discloses the explosion-proof outdoor automobile charging pile. When the fastening screw is mounted, the stressed area is increased through a base plate, so the wire core of the cable can be clamped by matching with the lug plate; the pressed spring applies an upward force to the lug plate, so the sufficient contact between the lug plate and the wire core of the cable is further ensured, and the limiting of the fastening screw is realized by matching a rivet and a fixing hole with the groove at the topof the fastening screw, so that the fastening effect of the fastening screw is ensured.

Description

technical field [0001] The invention relates to the technical field of automobile charging piles, in particular to an explosion-proof open-air automobile charging pile. Background technique [0002] The car charging pile is a power distribution facility for fast charging of electric vehicles. The existing connection methods between the car charging pile and the power grid are as follows: figure 1 As shown, the core of the cable and the lug at the bottom of the connector slot are fixed together by fastening screws, so as to realize the circuit connection between the grid and the charging pile. [0003] When the charging pile is working, its internal rotating components, such as cooling fans, will transmit the vibration during rotation to the connector. If things go on like this, the fastening screws will easily become loose, causing the cable core and the lug to separate. A gap is generated, which increases the equivalent resistance, increases the thermal effect of the curre...
