Description

Wiring harness insulation layer stripping device

Technical Field

The utility model relates to a power equipment technical field especially relates to a pencil insulating layer stripping off device.

Background

A communication line has a cable core formed of a plurality of wires or conductors insulated from each other and a sealing sheath provided outside the cable core. And an outer protective layer is also arranged outside the sheath. There are many laying modes such as overhead, direct burial, pipeline and water bottom. The cable is divided into symmetrical, coaxial and comprehensive cables according to the structure; it is divided into field operations and permanent cables according to functions. The communication cable has wider transmission frequency band, larger communication capacity and small external interference, but is not easy to overhaul. Telephone, telegraph, data and images can be transmitted. The strength and the elongation of the pure copper conductor are higher than those of a copper-clad aluminum conductor, namely the pure copper is better than that of the copper-clad aluminum in terms of mechanical property. From the perspective of cable design, the advantage of the mechanical strength of a pure copper conductor is better than that of a copper-clad aluminum conductor, and the pure copper conductor is not necessarily required in the practical application process. The copper-clad aluminum conductor is much lighter than pure copper, so that the copper-clad aluminum cable is lighter than a pure copper conductor cable in the whole weight, and convenience is brought to the transportation of the cable and the erection construction of the cable. In addition, copper-clad aluminum is a bit softer than pure copper, and the cable produced by using the copper-clad aluminum conductor is a bit better than the cable made of pure copper in the aspect of flexibility. Electrical performance. Because aluminum has poor conductivity compared with copper, the direct current resistance of the copper-clad aluminum conductor is larger than that of a pure copper conductor, which has no influence on whether the cable is used for supplying power, such as supplying power to an amplifier, and if the cable is used for supplying power, the copper-clad aluminum conductor will cause extra power consumption and more voltage reduction. When the frequency exceeds 5MHz, the ac resistance attenuation at this time is not clearly different between the two different conductors. This is, of course, mainly due to the skin effect of the high frequency current, the higher the frequency is, the closer the current flows to the surface of the conductor, and the surface of the copper-clad aluminum conductor is actually made of pure copper, and when the frequency is higher to a certain degree, the whole current flows in the copper material. At 5MHz, the current flows in a near-surface thickness of about 0.025 mm, while the copper layer thickness of the copper-clad aluminum conductor is about one times greater than this thickness. For the coaxial cable, the transmission effect of the copper-clad aluminum conductor and the pure copper conductor is the same because the transmitted signal is above 5 MHz. This is evidenced by the attenuation of the cable under actual testing. The copper-clad aluminum is softer than a pure copper conductor, and is easy to straighten in the production process, so that the return loss index of the cable using the copper-clad aluminum is better than that of the cable using the pure copper conductor to a certain extent.

In the traditional process, when a power cable needs to be connected, an insulating layer on the surface of the cable needs to be stripped, but in the prior art, the stripping strength is difficult to control and easily damages an internal metal wire core, so that the condition that the current at a joint is increased suddenly is caused.
