Embodiment 1

[0017] Embodiment 1: as figure 1 As shown, the cable for electric vehicle charging pile includes a cable core and an outer sheath 7. The cable core is jointly twisted into a cable by a pair of charging core 1, signal core 2 and grounding protection core 3. The cable core The outer circumference is wrapped with a filling layer 4, and the outer circumference of the filling layer 4 is wrapped with a polyester tape sliding layer 5, and the outer circumference of the polyester belt sliding layer 5 is covered with a stainless steel wire braided layer 6, and the stainless steel wire braided layer 6 An outer sheath 7 is extruded on the outer periphery of the charging wire core 1, and an insulating layer 103 is extruded on the outside after several copper wire conductors 101 are twisted around the rope core 102.

[0018] As a further improvement, the rope core 102 is a hemp core dipped in lubricating oil, the filling layer 4 is a glass fiber filling rope, the insulation layer 103 is ma...

Embodiment 2

[0025] Embodiment 2: as figure 2 As shown, the cable for electric vehicle charging pile includes a cable core and an outer sheath 7. The cable core is jointly twisted into a cable by a pair of charging core 1, signal core 2 and grounding protection core 3. The cable core The outer circumference is wrapped with a filling layer 4, and the outer circumference of the filling layer 4 is wrapped with a polyester tape sliding layer 5, and the outer circumference of the polyester belt sliding layer 5 is covered with a stainless steel wire braided layer 6, and the stainless steel wire braided layer 6 The outer periphery of the cable is extruded with an outer sheath 7, and the charging wire core 1 is composed of several copper wire conductors 101 first twisted into a single-strand wire, and then several single-strand wires are twisted around the rope core 102 and then an outer extruded insulation layer 103 is formed. .

[0026] As a further improvement, the rope core 102 is a hemp cor...

Abstract

The invention discloses a cable for an electric vehicle charging pile. The cable comprises a cable core and an outer sheath, the cable core is formed by twisting of charging wire cores, signal wire cores, and a grounding protection wire core, the periphery of the cable core is wrapped by a filling layer, the periphery of the filling layer is wrapped by a polyester tape slipping layer, the periphery of the polyester tape slipping layer is wrapped by a stainless steel wire braided layer, the periphery of the stainless steel wire braided layer is extruded by the outer sheath, and a plurality of copper wire conductors and a rope core are twisted in a winding manner and then extruded by an insulating layer to form each charging wire core. According to the cable for the electric vehicle charging pile, the flexibility is high, the tension and the bending resistance are good, green environmental protection is realized, and the service lifetime is long.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a cable for an electric vehicle charging pile and a manufacturing method thereof. Background technique [0002] In the face of increasingly serious energy, climate, and environmental problems, the development of electric vehicles has gradually become the consensus of the world. The cable for electric vehicle charging pile is the carrier used to transmit electric energy connected between the electric vehicle and the charging pile. It is one of the key equipment of the conductive charging system of electric vehicle. Mode: one is placed on the car, and the car is used in different environments; the other is placed on the charging pile in roads, shopping malls, parking lots, hotels, garages and other places. Regardless of the type, the charging cable may be affected by unfavorable conditions such as sunlight, weathering, oil, humidity, freezing, etc., and it is likely to be bent and ...
