Framework type wire passing ring

Abstract

The invention relates to a framework type wire passing ring which comprises a framework, wire passing hole and a protecting jacket, wherein the wire passing hole is arranged on the framework; an isolation convex ring is arranged at the middle part of the framework; a wire crossing groove is arranged on the isolation convex ring; a groove is arranged on the side surface of the framework; the protecting jacket is communicated with the wire passing hole; a binding clamp is arranged on the protecting jacket; and the binding clamp is away from the surface of the end of the framework. The framework type wire passing ring provided by the invention has the advantages that: the dust and moist air are prevented from entering an electric appliance case, the normal operation of a circuit board as well as elements and components in the electric appliance case is effectively guaranteed, and the winding is more compact and orderly due to the isolation convex ring arranged on the framework.

Description

technical field [0001] The invention relates to the field of cable protection, in particular to a skeleton type passing coil. Background technique [0002] In existing electrical products, there are parts that use metal electrical boxes. When cables (such as electric wires and signal lines) pass through metal electrical boxes, some protection is generally required to prevent the sharp edges of the electrical box from cutting the cables. One of the commonly used protection schemes is to protect some places where the wires pass through. For example, there is a coil on the sharp edge of the metal electrical box to isolate the power line from the metal. [0003] There is a gap between the wire hole of the existing coil and the outer surface of the wire, so that dust and humid air can enter the electrical box through the gap, which will cause dust to stick on the circuit board, which will lead to the control function of the circuit board after a long time Reduce or cause electri...

AI Technical Summary

Problems solved by technology

[0003] There is a gap between the wire hole of the existing coil and the outer surface of the wire, so that dust and humid air can enter the electrical box through the gap, which will cause dust to stick on the circuit board, which will lead to the control function of the circuit board after a long time Degrade or cause electrical failure or safety hazard

[0004] The insulation filling tape in the skeleton of the existing coil is wound to the required thickness in a layer-by-layer manner, which has many disadvantages: first, it is time-consuming and laborious, and the production efficiency is low; second, it is difficult to control the width and thickness, which makes the product The quality and parameters are difficult to control; the third is that the insulating filling tape is easy to slide, and the isolation effect cannot be achieved
