Heating cable with invisible joint and manufacturing method thereof

Abstract

The invention discloses a heating cable with an invisible joint and a manufacturing method thereof. The heating cable with the invisible joint comprises a heating segment and a lead segment, wherein the heating segment comprises a jacket layer, a shielding layer, an insulating layer, a high-temperature resistant insulating layer and a heating core; the lead segment comprises a jacket layer, a shielding layer, an insulating layer and a cold wire; the cold wire is connected with the heating core; and the jacket layer is provided with a joint mark. The manufacturing method comprises the following steps of: 1) manufacturing the high-temperature resistant insulating layer on the heating core; 2) cutting the heating core; 3) cutting the cold wire; 4) soldering the heating core and the cold wire; 5) finding out the joint; and 6) manufacturing the insulating layers, the shielding layers and the jacket layers. The heating cable with the invisible joint and the manufacturing method thereof have the advantages of: (1) improving the quality of the joint; (2) improving the high-temperature resistance of the cable; (3) improving the flexibility of the cable, so that the cable is difficult to break off when bent repeatedly; and (4) making the definite joint mark at the joint of the cold wire and the heating core.

Description

technical field [0001] The invention relates to a cable, in particular to a heating cable with invisible joints and a manufacturing method thereof. Background technique [0002] With the development of the economy and the improvement of people's living standards, people's requirements for heating methods in winter are also increasing, and electric floor heating was born. The level of electric floor heating in foreign countries is relatively developed, and the domestic electric floor heating has only been started for 10 years. The main working unit of electric floor heating is the heating cable, and the hot and cold wire joints of the heating cable are important factors affecting its quality and service life. Now there are two types of explicit joints and invisible joints in the market. The contact resistance of the explicit joints is large, and they will be overheated locally during working conditions. At the same time, waterproof and insulation problems are also insurmounta...

AI Technical Summary

Problems solved by technology

Now there are two types of explicit joints and invisible joints in the market. The contact resistance of the explicit joint is large, and it will overheat locally when it is working; at the same time, waterproof and insulation problems are also insurmountable problems.

The implicit joint overcomes the shortcomings of the explicit joint, but there are also problems such as poor high temperature resistance and easy breakage
