Description

Technical Field

[0001] The utility model relates to the technical field of sheathed flexible wires, and particularly relates to a light polyvinyl chloride sheathed flexible wire. Background Art

[0002] The polyvinyl chloride sheathed flexible wire is usually referred to as a sheathed cable, which means a single-core or multi-core wire with a polyvinyl chloride sheath layer to increase safety. The sheathed wire can be divided into two types: hard sheathed wire and soft sheathed wire. According to the application environment and shape, it can be divided into round sheathed wire and flat sheathed wire. Generally, the round sheathed wire is multi-core, and the flat one is usually single-core.

[0003] During the use of the existing polyvinyl chloride sheathed flexible wire, it needs to be connected to various wires. When the staff connects the polyvinyl chloride sheathed flexible wire to other wires, they need to first wind and fix the wire cores between the wires, and then wrap a large amount of electrical tape around the wire connection to insulate and fix the connection. If the wrapped electrical tape is not firm or has gaps, it will cause the polyvinyl chloride sheathed flexible wire to separate from the wire or allow dust and water to enter through the gaps, resulting in a short circuit of the circuit.

[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1 to 4 , the present utility model provides a technical solution: a light polyvinyl chloride sheathed flexible wire, including a soft wire body 1 and a wire 2 arranged inside the soft wire body 1. A protective layer for protecting the wire 2 is provided on the soft wire body 1. The protective layer can provide multiple protections for the wire 2 to avoid damage to the wire 2. An insulating sleeve 3 for protecting the wire 2 is provided at one end of the soft wire body 1. The insulating sleeve 3 is made of polyester fiber and has the characteristic of high temperature resistance. It will shrink after being heated to provide insulation protection for the connection of the wire 2.

[0021] Wherein, one end of the insulating sleeve 3 away from the flexible wire body 1 is fixedly connected with a fixing ring 4, and a plug 5 is fixedly connected to the inner side of the fixing ring 4, so that the insulating sleeve 3 is inserted into the interior of the flexible wire body 1 through the plug 5. The plugs 5 are distributed in a circumferential array on the fixing ring 4. After the insulating sleeve 3 is heated and shrunk, it will drive the fixing ring 4 to become smaller, making it more convenient for the plugs 5 to be inserted into the flexible wire body 1, and increasing the connection stability between the flexible wire bodies 1.

[0022] Wherein, the insulating sleeve 3 has a funnel-shaped structure, which is more conformable to the outer shape of the flexible wire body 1. And the large-mouth end is convenient for workers to connect the wires 2. There is a large operating space, and the connected wires 2 can also be placed inside the insulating sleeve 3, and then heated and shrunk by a lighter to protect the insulation at the connection of the wires 2.

[0023] Wherein, the protective layer includes a tensile layer 7. The flexible wire body 1 is sequentially provided with a wear-resistant layer 9, a matrix layer 8 and a tensile layer 7 from the outside to the inside. The wear-resistant layer 9 is made of nitrile rubber material. Nitrile rubber has high wear resistance and can improve the service life of the flexible wire body 1. The matrix layer 8 is made of polyvinyl chloride material. Polyvinyl chloride has good insulation performance and can well protect the circuit. The tensile layer 7 is made of glass fiber material. Glass fiber has good insulation, high heat resistance, good corrosion resistance and high mechanical strength, which improves the tensile property of the flexible wire body 1 and can also prevent the wire 2 from being corroded. A filling layer 6 is arranged between the wire 2 and the tensile layer 7, and the filling layer 6 can stably fix the wire 2 inside the flexible wire body 1.
