Description

[Technical field]

[0001] The utility model relates to the technical field of electric wires and cables, in particular to the technical field of industrial frequency spark machines. [Background technology]

[0002] The power frequency spark machine is a kind of detection device used to detect insulation defects such as bare copper, broken skin, pinholes, etc. of various cables. At the same time, it can mark the defective points to achieve better quality results. When the insulation skin of the cable is damaged, the exposed metal wire core contacts and conducts with the conductor (such as electrode beads) inside the power frequency spark machine, triggering the power frequency spark machine alarm (such as ringing, generating sparks, and counter counting, etc.). When the existing power frequency spark machine is in use, the cable usually passes through the power frequency spark machine. The power source that drives the cable movement is usually the subsequent process of winding the cable. The power frequency spark machine itself cannot drive the cable to move. When a new cable is being tested, it is usually necessary to open the upper cover before the cable can be pulled through the spark machine. The upper cover must be closed to allow the bead chain to fall on the cable. Every time a new cable is installed, it is necessary to stop the machine and open the cover, especially for cables with shorter lengths and larger numbers. It is more troublesome to detect broken skin. At the same time, the power supply is not cut off when the power frequency spark machine is opened, which may cause problems such as high voltage injury.

[0003] The existing patent CN117169663A discloses an industrial frequency spark machine for cable detection, which uses a movable arc-shaped clamp to pass the cable through the industrial frequency spark machine. The mechanism for driving the cable to move is relatively complex and costly, and the arc-shaped clamp will pass through the internal area of ​​the industrial frequency spark machine with high voltage. The mechanism for driving the cable to move is easily damaged by the high voltage. [Contents of the utility model]

[0004] The purpose of the utility model is to solve the problems in the prior art and to provide an industrial frequency spark machine for electric wire production, which can make the electric wire pass through the box conveniently and safely and has a simple structure.

[0005] To achieve the above-mentioned purpose, the utility model proposes an industrial frequency spark machine for electric wire production, comprising a box body, a box cover, a wire wheel, a conductive bead chain, a side opening window, and a lower opening window. The box body is covered with a box cover, and a detection cavity is formed inside the assembly formed by the box body and the box cover. A plurality of conductive bead chains are arranged inside the detection cavity, and the conductive bead chains are installed on the box cover.

A lower opening window is arranged on the bottom wall of the box body, and the lower opening window is in the shape of a long strip. The lower opening window connects the two side opening windows. First mounting frames are installed on the outer sides of the two side walls of the box body with the side opening windows, and a wire wheel is installed on the first mounting frame. When the two lower opening windows are horizontally passed by the electric wires, the two wire wheels hold the electric wires.

[0006] Preferably, one side of the box cover is hinged to the box body, and the box cover and the box body are locked together by a fixing lock, which is located on the opposite side of the hinged side of the box cover.

[0007] Preferably, two second mounting frames are installed at the bottom of the box body, and the second mounting frames are composed of two mounting plates, which are respectively located on both sides of the lower opening window, and mounting holes are provided on the mounting plates. An insulating plug is installed on the second mounting frame, and the insulating plug is parallel to the axis of the wire wheel. The insulating plug passes through the two mounting holes. The insulating plug consists of a head and a rod body.
