Description

Technical Field

[0001] The present application relates to the field of cables, and in particular to a device for detecting the surface insulation layer of electric wires. Background Art

[0002] The wire surface insulation layer is an important part of protecting the wire conductor. It can prevent electronic equipment from interacting with interference in the external environment, so it plays a vital role. The wire surface insulation layer may be damaged by various factors during the manufacturing process, which may cause the wire surface insulation layer to be loosely wrapped or otherwise damaged, thus affecting its normal use.

[0003] At present, the traditional method of detecting the surface insulation layer of wires is mainly to detect the surface insulation layer of wires by naked eye observation or with the help of a microscope. However, this method has problems such as low detection efficiency, low accuracy, complex operation and time-consuming. Therefore, it is necessary to provide a new wire surface insulation layer detection device that can quickly, accurately and efficiently detect the damage of the wire surface insulation layer. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this application is to provide a wire surface insulation layer detection device. The detector is connected to the wire reel and the coolant in the refrigeration box through two detection lines. By detecting circuit breaks and passages, it can quickly detect whether the wire surface insulation layer is damaged.

[0005] The above technical problems solved by the present application are achieved through the following technical solutions:

[0006] A wire skin insulation layer detection device comprises a fixed seat, a wire reel, a cooling box, a detector, a first detection line and a second detection line. Grooves are provided at both ends of the top of the fixed seat. Both ends of the wire reel are installed in the grooves. The wire reel is rotatably connected to the fixed seat. A locking plate is installed on the top of the fixed seat. The cooling box is arranged on one side of the fixed seat. One end of the first detection line of the detector is connected to the locking plate, and the other end of the second detection line is placed in the cooling box. The other ends of the first detection line and the second detector are connected to the detector.

[0007] By adopting the above technical solution, an insulating layer needs to be melted and adhered on the surface of the copper wire during the processing of the wire, and then it is cooled and formed by the coolant in the cooling box. One detection line of the detector is connected to the wire reel, and the other detection line is placed in the coolant in the cooling box. In this way, a loop can be formed. When the insulating layer of the wire wound up by the wire reel is not damaged, the loop is disconnected, and the resistance in the loop is infinite. When the insulating layer is damaged, the loop is a passage, so there will be resistance. The damaged insulating layer can be quickly identified by the resistance value on the detector.

[0008] According to a further optimization scheme, the detector is a multimeter.

[0009] By adopting the above technical solution, the resistance value detected by the multimeter is accurate and the response is fast, and the damaged insulation layer can be accurately detected.

[0010] According to a further optimization solution, the fixing seat is made of a non-conductive material.

[0011] According to a further optimization scheme, both ends of the locking plate are connected to the fixing seat by bolts.

[0012] According to a further optimization solution, the locking plate is an arc-shaped plate.

[0013] By adopting the above technical solution, the arc-shaped locking plate can fit more closely with the rotating shaft of the cable reel, preventing separation during rotation and affecting the accuracy of detection. The two ends of the locking plate are connected to the fixing seat by bolts. When the cable reel needs to be replaced, it can be taken out by simply removing the bolts.

[0014] According to a further optimization scheme, a blocking plate is installed on each of the left and right opposite side walls of the cooling box, and a guide shaft is rotatably installed between the two blocking plates.

[0015] By adopting the technical solution, the electric wires are transmitted on the guide shaft, thereby preventing the insulation layer from being damaged.

[0016] According to a further optimization scheme, an insulating layer is provided on the inner surface of the cooling box.

[0017] By adopting the above technical solution, the insulating layer on the inner surface of the cooling box can be insulated from the ground, which can increase the accuracy of detection by the detector.

[0018] According to a further optimization scheme, a water valve is installed at the bottom of the side wall of the cooling box, and a faucet is installed on one side of the cooling box.

[0019] By adopting the above technical solution, the insulating layer needs to be cooled and shaped after being wrapped around the wire, the faucet on the cooling box will fill water into the cooling box, and when the cooling water in the cooling box is too high, the water can be drained through the water valve, thereby ensuring the cooling and shaping effect of the cooling box on the insulating layer.

[0020] In summary, the beneficial technical effects of this application are:

[0021] One detection line of the detector is connected to the wire reel, and the other detection line is placed in the coolant in the cooling box, so that the detector, the wire reel and the cooling box form a loop through the two detection lines. When the insulation layer of the wire wound up by the wire reel is not damaged, the loop is disconnected, and the resistance in the loop is infinite. When the insulation layer is damaged, the loop is a passage, so there will be resistance. The damaged insulation layer can be quickly identified by the resistance value on the detector. The detection equipment has a simple structure and can quickly, accurately and efficiently detect damage to the wire surface insulation layer. BRIEF DESCRIPTION OF THE DRAWINGS
