Stable and conveniently assembled and dissembled multiple-conductive-core cable and manufacturing method therefor

Abstract

The invention discloses a stable and conveniently assembled and dissembled multiple-conductive-core cable. The cable comprises an outer protection layer and cable inner core conductors arranged in an inner cavity of the outer protection layer. The invention also discloses a manufacturing method for the stable and conveniently assembled and dissembled multiple-conductive-core cable; the method comprises the following steps of S1, preparing a traction rope, the outer protection layer and the cable inner core conductors of a to-be-threaded cable; S2, fixing and tightening one end of the traction rope at one ends of the cable inner core conductors, meanwhile, enabling one end with a hook to be penetrated through the inner cavity of the outer protection layer; S3, fixing the hook by a drawbench or a traction apparatus, and performing traction operation on the cable inner core conductors; and S4, controlling the traction speed to be not greater than 3m / min until the threading of the cable inner core conductors is completed. A rotary wheel mounting groove and an auxiliary rotary wheel apparatus are arranged in the inner cavity of the outer protection layer, so that convenience in the cable threading process can be well ensured, and structural completeness can be guaranteed; the method is applicable to design of a relatively short cable; and after maintenance, the safety is relatively high and is not affected.

Description

technical field [0001] The invention relates to the related technical field of cable products, in particular to a stable multi-conductor cable and a processing method thereof that can be installed and disassembled easily. Background technique [0002] Cables are usually wound and rolled by several groups or wires, including outer protective skin, inner core wires, insulation layer, shielding layer and filling structure. In the production process of cables, the inner core wires are usually wound. After finishing, use the mold to pour the outer protective skin on the outer surface of the inner core wire to form a complete cable for use. In the prior art, the filling structure of the cable is usually filled with the overall cavity to ensure The stability and enrichment of the cable, this method not only wastes material, but also causes difficulty in separating the inner core of the cable conductor. It is laborious and time-consuming during traction production, and for this kin...

[0002] Cables are usually wound and rolled by several groups or wires, including outer protective skin, inner core wires, insulation layer, shielding layer and filling structure. In the production process of cables, the inner core wires are usually wound. After finishing, use the mold to pour the outer protective skin on the outer surface of the inner core wire to form a complete cable for use. In the prior art, the filling structure of the cable is usually filled with the overall cavity to ensure The stability and fullness of the cable, this method not only wastes material, but also causes difficulty in separating the inner core of the cable conductor

It is labor-intensive and time-consuming during traction production. In view of this problem, the present invention proposes
