Description

Technical Field

[0001] The utility model relates to the technical field of twisting moulds, in particular to a twisting mould for longitudinal waterproof conductors. Background Art

[0002] Longitudinal waterproof conductors are usually made of multiple insulated conductor cores twisted together. In order to ensure the insulation and waterproof performance between the conductor cores, a special twisting die is required. Through reasonable design and material selection, the twisting die of the longitudinal waterproof conductor can ensure the twisting quality and waterproof performance of the conductor cores, and improve the reliability and durability of the conductor. The twisting die usually adopts a rotary twisting method, and the conductor core is wound into a spiral shape by rotating the die to form the structure of the longitudinal waterproof conductor. During the twisting process, the twisting speed and tension need to be controlled to ensure that the conductor cores are twisted tightly and evenly.

[0003] The existing longitudinal waterproof conductor twisting mold, when in use, needs to maintain the appropriate tension of the insulated conductor in order to ensure that the insulated conductor is twisted evenly on the conductor core. The appropriate tension can make the insulated conductor twisted tightly and evenly. If the tension of the insulated conductor is too large, it may cause uneven twisting and easy breakage. The appropriate tension can reduce the number of shutdowns during the twisting process. However, the current twisting mold is more troublesome when it stops to adjust the tension of the insulated conductor, and there is a disadvantage of inconvenient tension adjustment, and the production and operation efficiency is low.
