Benefits of technology

This new design allows for better flexility, larger bends, longer lifespan than previous designs. It also makes it easier to use this type of cable when there are only one room available at home or on an airport lot where installation may take place more frequently.

Problems solved by technology

This technical problem addressed by this patented technology relates to reducing the size or number of bushings needed while still maintaining their effectiveness at transmitting signals over long distances without causing damage from external factors such as vibrations caused during use.

Embodiment Construction

[0022] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings to describe the technical solution of the present invention in detail.

[0023] Such as figure 1 As shown, the control cable of the present invention includes a cable conductor formed by twisting a bundle of multiple copper single wires, and an insulating layer 2 is extruded outside the cable conductor, and the insulating layer 2 adopts JR-70 type soft polychlorinated Vinyl insulating material, the JR-70 type soft polyvinyl chloride insulating material is a commercially available product, and its Shore hardness is 10-85 degrees. In this embodiment, the Shore hardness is 40 degrees. The pitch-to-diameter ratio of the cable conductors ranges from 1:1 to 9:1, and the pitch-to-diameter ratio in this embodiment is 5:1.

[0024] A layer of tape 4 is wrapped around the outside of the cable conductor. The wrapping tension of the wrapping tape 4 during the wrapping pr

Abstract

The invention discloses a controlling cable and a manufacturing method thereof. The controlling cable comprises a cable core, a layer of belting is arranged on the exterior of the cable core, an outer sheath is arranged on the exterior of the belting, the cable core comprises a cable conductor and an insulating layer, the cable conductor is bundled and twisted by multistrand of copper single wires, and the insulating layer is wrapped on the exterior of the cable conductor. The manufacturing method includes that step one, multistrand of copper single wires are bundled and twisted to form the cable conductor; step two, the insulating layer is formed on the exterior of the cable conductor in an extrusion molding mode to form the cable core; step three, the belting is lapped on the exterior of the cable core, and the lapping tension of the belting is smaller than 50 newtons; and step four, the outer sheath is formed on the exterior of the belting in the extrusion molding mode. According to the controlling cable and the manufacturing method thereof, compared with existing cables, the controlling cable has the advantages of being good in softness, high in flexibility, and long in service life, besides, the manufacturing method of the controlling cable can enhance the softness and flexibility of the finished cable, so that the controlling cable can be widely used for laying equipment occupying small space.
