Description

Technical Field

[0001] The utility model relates to the field of cables, specifically a sensor connecting wire. Background Technique

[0002] A sensor connecting wire, that is, a connecting wire used on various sensors, plays a role in finding signals and connecting signals.

[0003] For example, the patent with the application number CCN202321821960.5 discloses an automotive flexible sensor connecting cable, including an automotive flexible sensor connecting cable body. The automotive flexible sensor connecting cable body includes a sheath, the sheath is arranged outside the automotive flexible sensor connecting cable body, and the sheath includes a plastic layer and a wear-resistant coating, and the wear-resistant coating is arranged outside the plastic layer.

[0004] The above patent realizes adding nylon filaments in the conductor material to increase the tensile force of the conductor, and adding multiple strands of cotton threads in the filler to ensure that the inside of the core wire remains a round state, ensuring the role of enhancing compressive resistance and increasing traction tensile force when the wire is bent, so that the cable can reach 1 million times of bending, and setting the sheath material of the wire to TPU material. The TPU material has good resilience, is oil-resistant, water-resistant, and mold-resistant, and still maintains good elasticity, flexibility and other physical properties at low temperature, increasing the service life of the connecting cable; however, the disadvantage of the above patent is that the compressive resistance of the above patent is poor, and when the cable is radially compressed, the cable is prone to deformation and the cable is damaged.

[0005] Therefore, it is necessary for us to improve such a structure to overcome the above defects. Summary of the Utility Model

[0007] To achieve the above purpose, the utility model provides the following technical solutions:

[0008] The sensor connecting wire includes several wire cores that are twisted together; an inner insulating layer is wrapped around the outside of the wire cores, and at the same time, a shielding layer is also wrapped around the outer wall of the inner insulating layer. The shielding layer is formed by winding aluminum foil around the inner insulating layer; the wire cores, the inner insulating layer, and the shielding layer form an independent wire. At least three independent wires are provided, and the three independent wires are arranged in a circular array; at the same time, an outer insulating layer is also coated around the periphery of the three independent guiding wires; first bending slots, second bending slots, third bending slots, and fourth bending slots are also opened on the outer wall of the outer insulating layer. The first bending slot, the second bending slot, the third bending slot, and the fourth bending slot are all arc-shaped and have an angle of 90 degrees; a support skeleton assembly is also provided inside the outer insulating layer. The support skeleton assembly includes several skeleton units, and the skeleton units are made of hard plastic; the skeleton unit includes a central column and at least three wing plates connected to the outside of the central column; the three wing plates are arranged in a circular array, and the independent wire is located between adjacent wing plates.

[0009] Further, both the inner insulating layer and the outer insulating layer are made of PTFE material.

[0010] Further, the first bending slot, the second bending slot, the third bending slot, and the fourth bending slot are arranged at an interval of 2 mm from each other, and the adjacent first bending slot, second bending slot, third bending slot, and fourth bending slot are arranged in a 90-degree angle staggered manner.

[0011] Further, a spherical card slot is provided at one end of the central column, and a connecting ball head is integrally formed at the other end of the central column. The connecting ball head of the skeleton unit is rotatably arranged in the spherical card slot of the adjacent skeleton unit, so that the adjacent skeleton units can rotate without disengaging.

[0012] Further, the support skeleton assembly also includes nylon wires, and at the same time, a wire hole for the nylon wires to pass through is opened in the center of the skeleton unit.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] When the connecting wire is radially compressed, the skeleton unit made of hard plastic can play a supporting role, and the rotational cooperation of the connecting ball head and the spherical card slot can also enable the connecting wire to be bent; at the same time, a relatively thick outer insulating layer can be used to ensure better protection performance, and the present utility model has strong radial compressive ability.
