Novel telescopic wire and manufacturing method thereof

Abstract

The invention relates to a novel telescopic wire and a manufacturing method thereof. The novel telescopic wire comprises an elastic core body and a conductor, the elastic core body is cylindrical elastic plastic, the conductor is a slender wire, the wire is wound on the periphery of the elastic core body, and the winding shape of the wire is spiral; the periphery of the elastic core body is also wound with an insulating thin wire, the insulating thin wire is also spirally wound, meanwhile, the insulating thin wire is woven on the wire, and the insulating thin wire and the wire are interwoven with each other. According to the novel telescopic wire designed in the scheme, in order to solve the technical problems that the wire is easy to wear and the coating part is easy to crack due to the fact that the insulating coating part is arranged outside the wire of the disclosed telescopic wire, the coating part on the periphery of the wire is canceled, and the insulating fine wire is woven onthe wire; the insulating thin wire and the wire are interwoven together to form a whole and are wound on the periphery of the elastic core body, and the structure can effectively solve the technical problem.

Description

technical field [0001] The invention relates to a telescopic wire used in the industrial field, and mainly relates to a novel telescopic wire used in the robot field. Background technique [0002] Electric wires are generally formed with a copper wire as the core and the outer periphery is covered with an insulator, and have no stretchability. Typical examples of stretchable electric wires include coiled wires used in fixed telephones, etc., but they are usually thick and thin. Heavy. [0003] In the field of robot manufacturing, the wiring of the robot needs to leave a lot of room for wiring. In many cases, this becomes an obstacle in device design and practicality, and the retractable wire can be applied to the field of robot manufacturing. technology, the application number is: 200780048330.6 in the disclosed stretchable electric wire and its manufacturing method, a kind of stretchable electric wire is designed, it is mentioned that "has a structure formed by at least a ...

[0002] Electric wires are generally formed with a copper wire as the core and the outer periphery is covered with an insulator, and have no stretchability. Typical examples of stretchable electric wires include coiled wires used in fixed telephones, etc., but they are usually thick and thin. Heavy

[0003] In the field of robot manufacturing, the wiring of the robot needs to leave a lot of room for wiring. In many cases, this becomes an obstacle in device design and practicality, and the retractable wire can be applied to the field of robot manufacturing. technology, the application number is: 200780048330.6 in the disclosed stretchable electric wire and its manufacturing method, a kind of stretchable electric wire is designed, it is mentioned that "has a structure formed by at least a core part, a conductor part and a cladding part, the core part It is an elastic cylindrical body formed by an elastic body and an intermediate layer covering the outer periphery of the elastic body, the conductor part includes a conductor wire formed by a collection of thin wires, and the conductor wire is wound and / or braided on the elastic circle The outer periphery of the cylinder, the covering part is an outer covering layer formed by an insulator covering the outer periphery of the conductor part." In this patent document, the covering layer is wrapped around the outside of the conductor wire, and the conductor wire is wound on an elastic There is a defect in this structure. When stretched, the elastic body will stretch together with the conductor wire, but the wrapping layer has no elasticity. Therefore, when the stretching line of this structure is stretched, the wrapping layer and the conductor body There will be relative friction between the two, and it is easy to cause damage to the conductor wire after multiple stretches for a long time. At the same time, because the wrapping layer is not elastic, when the stretching line is stretched as a whole, it will cause cracks in the wrapping layer
