Description

Technical Field

[0001] The utility model relates to the technical field of charging pile cables, and in particular to a tensile-resistant and high-temperature-resistant charging pile cable. Background Art

[0002] As the electric vehicle market continues to grow, charging piles have become essential equipment in public places, small and medium-sized parking lots, and home garages. As a channel connecting electric vehicles and charging piles, charging pile cables have the function of transmitting power, data signals, and status information, and can realize functions such as battery charging and battery management.

[0003] The patent with publication number CN218004450U proposes a tensile and heat-resistant charging pile cable, which improves the cable's tensile dragging ability and tear resistance by adopting a silicone rubber sheath, fine steel wire braided armor and reinforcing ribs, and improves the cable's high temperature and heat resistance by setting an isolation layer and a protective layer, avoiding the occurrence of safety hazards and extending the service life of the cable. However, the cable has the following disadvantages: Since the insulating layer on the surface of the cable is extruded by an extruder, it is relatively difficult to add reinforcing ribs inside the cable, thereby increasing the production cost of the cable. In addition, although the cable has good thermal insulation properties, it does not have good fire resistance when encountering open flames, so it needs further improvement. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a tensile and high temperature resistant charging pile cable.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a tensile-resistant and high-temperature resistant charging pile cable, including a wire body, the wire body includes a plurality of wire cores, a wrapping layer is provided on the surface of the plurality of wire cores, a filling rope is provided inside the wrapping layer and in the gaps between the plurality of wire cores, an armor layer is sleeved on the surface of the wrapping layer, a heat insulation layer is sleeved on the surface of the armor layer, a fireproof layer is sleeved on the surface of the heat insulation layer, an outer insulating layer is sleeved on the surface of the fireproof layer, rings are sleeved on the surfaces of both ends of the wire body, two side walls of the rings are connected to fixing components, and a tensile-resistant component is connected between the two rings.

[0007] Furthermore, the wrapping layer is made of non-woven fabric material, the armor layer is made of steel belt, the heat insulation layer is made of silicone rubber material, and the fireproof layer is made of asbestos material.

[0008] Furthermore, the fixing assembly includes an arc plate located inside the ring and a screw rod passing through the ring, the screw rod is threadedly connected to the ring, one end of the ring located inside the ring is rotatably connected to the arc plate, and the other end of the screw rod is fixedly connected to a knob.

[0010] Furthermore, the tensile assembly includes a stud fixed to one side of the two rings, the surface of the stud is threadedly rotatably connected with an internal threaded sleeve, and a steel wire is fixedly connected between the two internal threaded sleeves.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1-Figure 4 As shown, it relates to a tensile-resistant and high-temperature resistant charging pile cable, including a wire body 1, the wire body 1 includes a plurality of wire cores 2, a wrapping layer 4 is provided on the surface of the plurality of wire cores 2, a filling rope 5 is provided inside the wrapping layer 4 and in the gaps between the plurality of wire cores 2, an armor layer 6 is sleeved on the surface of the wrapping layer 4, a heat insulation layer 7 is sleeved on the surface of the armor layer 6, a fireproof layer 8 is sleeved on the surface of the heat insulation layer 7, an outer insulating layer 9 is sleeved on the surface of the fireproof layer 8, rings 10 are sleeved on the surfaces of both ends of the wire body 1, fixing components 11 are connected to the side walls of the two rings 10, and a tensile-resistant component 12 is connected between the two rings 10.

[0023] The surfaces of the plurality of wire cores 2 are sleeved with inner insulating layers 3 , and both the inner insulating layer 3 and the outer insulating layer 9 are made of cross-linked polyethylene material.

[0024] The cross-linked polyethylene material has the advantages of good heat resistance, corrosion resistance and pressure resistance, and the two layers of insulation can better protect the internal wire core 2.

[0025] The wrapping layer 4 is made of non-woven fabric material, the armor layer 6 is made of steel tape, the heat insulation layer 7 is made of silicone rubber material, and the fireproof layer 8 is made of asbestos material.

[0026] The armor layer 6 can provide preliminary protection for the inner core 2, and the heat insulation layer 7 can further improve the high temperature resistance of the cable. The fireproof layer 8 can block open flames on the outer layer, thereby improving the fireproof ability of the cable.

[0027] The fixing assembly 11 includes an arc plate 111 located inside the collar 10 and a screw rod 112 penetrating the collar 10 . The screw rod 112 is threadedly connected to the collar 10 . One end of the collar 10 located inside the collar 10 is rotatably connected to the arc plate 111 , and the other end of the screw rod 112 is fixedly connected to a knob 113 .

[0028] By rotating the knob 113 , the arc plate 111 can be driven to press the surface of the wire body 1 , so that the ring 10 is fixed on the surface of the wire body 1 .

[0029] The cross section of the connection between the screw rod 112 and the arc plate 111 is T-shaped. Therefore, the screw rod 112 can be driven to move by rotating the knob 113, and the screw rod 112 can push or pull the arc plate 111 to move.

[0030] The tensile assembly 12 includes a stud 121 fixed to one side of the two collars 10 , an internal thread sleeve 122 is rotatably connected to the surface of the stud 121 , and a steel wire 123 is fixedly connected between the two internal thread sleeves 122 .

[0031] By using the steel wire 123 to bear the tension instead of the wire body 1 itself, the wire body 1 can be prevented from being damaged when being pulled, thereby improving the tensile strength of the cable. In addition, the tensile component 12 disposed outside the wire body 1 has lower production costs and difficulty. In addition, since the steel wire 123 is connected to the stud 121 through the internal thread sleeves 122 at both ends, when the steel wire 123 breaks, the internal thread sleeves 122 can be unscrewed to replace the steel wire 123.

[0032] Working principle: When installing the ferrule 10 and the tensile component 12, the two ferrules 10 can be moved along the surface of the wire body 1 until the ferrule 10 moves to the two ends of the wire body 1, and then the knob 113 is turned to drive the screw 112 and the arc plate 111 to move, and the arc plate 111 is squeezed on the surface of the wire body 1 to fix the ferrule 10. It should be noted that when installing the two ferrules 10, it is necessary to ensure that the length of the wire body 1 between the two ferrules 10 is greater than the length of the steel wire 123, so that when pulling the two ends of the wire body 1, the steel wire 123 will be subjected to force first, thereby protecting the wire body 1.
