A new energy vehicle charging pile cable

Abstract

The invention discloses a new energy automobile charging pile cable, and the cable comprises three power cable cores and one signal control cable core. The cable also comprises a polyimide adhesive tape cabling wrapping layer which wraps the three power cable cores and the signal control cable core; filling layer which are disposed among the polyimide adhesive tape cabling wrapping layer, the three power cable cores and the signal control cable core; a waterproof resin coating which coats the polyimide adhesive tape cabling wrapping layer; a shielding wrapping layer which wraps the waterproof resin coating; and a rubber sheath wrapping the shielding wrapping layer in an extruding manner. Each power cable consists of a plurality of soft copper wire twisted conductors, a rubber insulating layer wrapping the plurality of soft copper wire twisted conductors, and a teflon adhesive tape wrapping layer wrapping the rubber insulating layer. The signal control cable core comprises three signal transmission control lines; a tinned copper braided layer wrapping the three signal transmission control lines; a shielding filling layer disposed between the tinned copper braided layer and the three signal transmission control lines; and a teflon adhesive tape wrapping protection layer wrapping the tinned copper braided layer.

Description

technical field [0001] The invention relates to a cable, in particular to a new energy vehicle charging pile cable. Background technique [0002] The function of the charging pile is similar to that of the fuel dispenser in the gas station. It can be fixed on the ground or on the wall, and installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential area parking lots or charging stations. Charge all models of electric vehicles. The input end of the charging pile is directly connected to the AC grid, and the output end is equipped with a charging plug for charging the electric vehicle. Charging piles generally provide two charging methods: conventional charging and fast charging. People can use a specific charging card to swipe the card on the human-computer interaction interface provided by the charging pile to perform corresponding charging methods, charging time, and cost data printing. The display screen of the charging pil...

Problems solved by technology

In the prior art, the charging cables used are ordinary flexible cables, which cannot meet the strict requirements of rolling resistance, oil resistance, low temperature resistance, water resistance, winding resistance, and flame retardancy of electric charging pile facilities and automobile batteries, especially when used at high speeds. The cables of road charging stations cannot adapt to the service life required for high-frequency movement like a refueling gun. In addition, environmental conditions such as sunlight, weathering, humidity, oil, freezing, high temperature, and mechanical conditions such as tension, pressure, and friction should also be fully considered. , and there is no standard for the charging cable supporting the electric vehicle charging station, and there is no fixed structural model
