Embodiment 1

[0026] The embodiment of the present application discloses a processing technology for an easy-peeling sheath cable, which includes the following steps:

[0027] Step S1: extruding to form an insulated wire core;

[0028] Step S2: Twisting the insulated wire cores in step S1 to make a cable core, wherein the cabled pitch is L, the cabled outer diameter is D, and L=24D. This step is mainly to control the cabled pitch , because the inside of the extruded sheath is in direct contact with the cable core, a threaded inner surface will be formed. In the actual production process, the size of the pitch has a great influence on the friction between the sheath and the cable core, and the larger the pitch, The smaller the friction force, in order to increase the pitch of the inner surface of the sheath, when the insulated core wire is cabled, the cabled pitch is controlled to be 24 times the outer diameter of the cabled cable, and the accuracy of the cabled pitch is improved at the same...

Embodiment 2

[0037] Compared with Example 1, the embodiment of the present application changes the ratio of the cable pitch to the cable outer diameter, so that L=24.5D.

Embodiment 3

[0039] Compared with Example 1, the embodiment of the present application changes the ratio of the cable pitch to the outer diameter of the cable so that L=25D.

[0040] The influence of cable pitch times, mold core, mold sleeve value and talc powder on the required peeling force will be explained separately below.

[0041] Table 1. Effect of Cable Pitch Ratio on Required Peel Force

[0042]

[0043] Comparative examples 1-5 in Table 1 in the embodiment of the present application are that the inner diameter of the die sleeve=cable outer diameter+2*mold sleeve wall thickness+3*sheath thickness, between the cable core and the sheath are smeared with Comparison in the case of 1200 mesh talcum powder;

[0044] From table 1, it can be drawn that along with the value of the cable-forming pitch ratio gradually increasing, the required peeling force will gradually decrease, and when the value of the cable-forming pitch ratio reaches 24, the required peeling force reaches the minim...

Abstract

The invention discloses a processing technology of an easy-to-peel sheathed cable. The processing technology comprises the following steps: S1, extruding to prepare insulating wire cores; S2, cablingand stranding the insulated wire cores in the step S1 to prepare a cable core, the cabling pitch being L, the cabling outer diameter being D, and L = 24D-25D; S3, extruding the cable core in the stepS2, so that the cable core is wrapped with a sheath to form a cable; and S4, taking up and packaging the cable in the step S3. The technical problem that a sheath in the cable is difficult to peel offin the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of cable processing technology, in particular to a processing technology of an easy-peeling sheath cable. Background technique [0002] After the cable is cabled, the sheath needs to be extruded. At present, domestic manufacturers often wrap a layer of tape around the cable core and then extrude the sheath, resulting in an extra process and more garbage during the assembly of the wire harness, and the tape is canceled. Directly extruding the sheath on the cable core will cause the sheath to be difficult to peel off manually due to the adhesion between the sheath and the insulation, and it is necessary to completely cut off the sheath of the assembled joint, which will easily cause the insulated wire to be scratched Therefore, it is necessary to invent an easy-to-peel sheath production process that can reduce the scrap rate during product assembly, significantly improve cable assembly efficiency, and improve ...
