Description

Technical Field

[0001] The utility model belongs to the technical field of automobile wires, in particular to an anti-aging thin-wall automobile wire. Background Art

[0002] With the advancement of technology and the intensification of competition, automotive wires have a trend of being lightweight and miniaturized, that is, the weight of the wires is reduced, the wire diameter is reduced, and the insulation wall thickness is thinner. However, the wires laid in the car body are inevitably subjected to mechanical vibration during use, which causes friction, resulting in wear of the insulation layer and electrical breakdown, which seriously endangers the safety of the car. Therefore, an important prerequisite for lightweighting and miniaturization of automotive wires is to ensure the wear resistance of automotive wires. In addition, automotive wires also need to have heat resistance, flame retardancy and processing performance.

[0003] The Chinese patent discloses a wear-resistant thin-walled polyvinyl chloride insulated automotive wire (authorization announcement number CN202434226U), including a conductor and an insulating layer; the conductor is a stranded conductor; the stranded conductor is formed by twisting 19 conductor monofilaments with a diameter of 0.182±0.3mm, and the total cross-sectional area of the conductor is 0.480-0.510mm2; the insulating layer is a polyvinyl chloride insulating material; the insulating layer is extruded on the surface of the conductor with a thin-walled structure; the thickness of the insulating layer is between 0.22-0.40mm;

[0004] Although the wear resistance of the automotive wires is improved by optimizing and controlling the conductor structure, insulation thickness and outer diameter of the polyvinyl chloride insulated automotive wires, when the automotive wires are actually used, their joints are usually exposed between automotive components. When auto repair personnel are inspecting and repairing automotive components, it is easy to collide with the joints, resulting in poor contact of the automotive wires. Therefore, an anti-aging thin-wall automotive wire is proposed. Utility Model Content

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0021] As Figures 1 to 4 shown, the present invention provides an anti-aging thin-walled automobile wire, which includes two automobile wire bodies 1. The automobile wire body 1 is mainly composed of a protective layer 101, a drying layer 102, a heat insulation layer 103, a buffer layer 104, a steel wire armor layer 105, a filling layer 106 and a conductor 107. The protective layer 101 is made of a material with high temperature resistance and corrosion resistance to protect the wire body from the influence of the external environment. The drying layer 102 is sleeved inside the protective layer 101 and is made of a material that can absorb moisture (such as calcium chloride) to maintain a dry environment inside the wire body and prevent aging caused by moisture. The heat insulation layer 103 is sleeved inside the drying layer 102 and is used to isolate high temperature to ensure that the structure of the inner layer of the wire body is not affected by high temperature. The buffer layer 104 is sleeved inside the heat insulation layer 103. The buffer layer 104 provides elasticity and softness to protect the wire body from being damaged by folding, and at the same time enhances the overall durability of the wire body. The steel wire armor layer 105 is sleeved inside the buffer layer 104. The setting of the steel wire armor layer 105 makes the automobile wire body 1 have the excellent characteristics of high tensile strength and continuous wire without swinging, extends the service life of the product, and avoids safety accidents caused by the fracture of the conductor 107. The filling layer 106 is sleeved inside the steel wire armor layer 105. The filling layer 106 is a flame-retardant fiber material structure, so that the automobile wire body 1 has the function of flame retardancy and waterproofness, thus bringing convenience to people's use. The conductor 107 is sleeved inside the filling layer 106.

[0022] One end of each of the two automobile cable bodies 1 is fixedly installed with a connector 2, the two connectors 2 are plugged in, and a protective component is arranged between the two automobile cable bodies 1, the protective component includes a movable ring 3 that is slidably sleeved on the outside of the two automobile cable bodies 1, the movable ring 3 is made of a hard insulating material, and the sides of the two movable rings 3 are annularly and equidistantly fixedly connected with four fixing frames 4, the fixing frames 4 are made of the same material as the movable rings 3, and one end of the four fixing frames 4 is fixedly installed with a protective cover 5, the two protective covers 5 fit together, and when the two connectors 2 are plugged in and used, the two protective covers 5 fit together, so that the two connectors 2 can be covered in the two protective covers 5, this method can effectively prevent other parts in the car from directly colliding with the connection between the two connectors 2 when they fall off, thereby playing a certain protective role.

[0023] One end of the outer side of one of the protective covers 5 is fixedly connected with four buckles 6 at equal intervals in an annular manner, and one end of the outer side of the other protective cover 5 is fixedly connected with four clamping blocks 7 at equal intervals in an annular manner. The four clamping blocks 7 are respectively clamped with the four buckles 6. Figure 1 and attached Figure 4 When the two connectors 2 are plugged in, one of the car cable bodies 1 can be rotated until the four buckles 6 are connected to the four blocks 7, and then the two protective covers 5 are tightly fitted.

[0024] The two car wire bodies 1 are fixedly sleeved with a fixed ring 8 on one side close to the joint 2. The fixed ring 8 is made of the same material as the movable ring 3. The outer side of the car wire body 1 is slidably sleeved with a return spring 9. Figure 4 At this time, the return spring 9 is in a compressed state and has a certain elastic potential energy. One end of the return spring 9 is fixedly connected to one side of the movable ring 3, and the other end of the return spring 9 is fixedly connected to one side of the fixed ring 8. By utilizing the elastic potential energy of the return spring 9, the protective cover 5 can automatically return to its initial position when no force is applied.

[0025] The working principle and process of this utility model are as follows:

[0026] During use, after the two automobile cable bodies 1 are plugged and connected through the joint 2, the user simultaneously pulls the two protective covers 5 in the direction of approaching each other, and the protective covers 5 are forced to move and drive the four fixing frames 4 to move, and the movement of the four fixing frames 4 drives the movable ring 3 to slide on the automobile cable body 1, and the sliding of the movable ring 3 causes the reset spring 9 to be compressed. After the two protective covers 5 are fitted to each other, the user rotates one of the automobile cable bodies 1 clockwise or counterclockwise until the four clamping blocks 7 are respectively clamped in the four buckles 6. At this time, the two protective covers 5 can protect the two joints 2, and during use, the properties of the automobile body 1 are utilized to effectively improve the flame retardant, waterproof and anti-aging effects of the automobile body 2, and the safety factor of the automobile cable body 1 during use is improved.
