Abstract

The invention belongs to the technical field of power cables, and discloses a connecting structure based on a PTC carbon heating cable. The connecting structure comprises a heating cable, a connectorand an external connection cable; a through hole is formed inside the connector, the through hole comprises a first section hole and a second section hole, and steps are arranged at the portion wherethe first section hole and the second section hole are communicated; one end of the heating cable stretches into the first section hole, one end of the external section cable stretches into the secondsection hole, and the heating cable and the external connection cable are connected at the steps; an inner cavity of the through hole is provided with a sealing layer, and a heat insulation layer isarranged at the inner surface of the sealing layer. The electricity consumption safety is improved, and the probability of electric shock and electric leakage is lowered; meanwhile, the heating efficiency of the heating cable is improved, power consumption is lowered, the phenomenon of partial heating is avoided, the service life of the heating cable is prolonged, the heating cable can automatically adjust the temperature according to changes of the surrounding environment temperature, and compared with similar products, more energy is saved; accordingly, the structure is suitable for being used and popularized.

Description

technical field [0001] The invention belongs to the technical field of power cables, and in particular relates to a connection structure based on PTC carbon heating cables. Background technique [0002] At present, there are a large number of heating cables used in domestic heating. The heating cables are generally laid below the ground, and generate heat after power-on, which helps the indoor space to generate heat, increases the indoor temperature, and facilitates the improvement of indoor comfort. [0003] However, most of the current cables use metal wires, carbon crystals or carbon fiber wires for heating. The heating cables in the prior art have a variety of problems, for example: the heating cables have high energy consumption and low heating efficiency; the existing heating cables take a long time to heat up, and the local temperature is often too high, which is easy to damage the cables At the same time, it endangers the safety of personnel; the existing heating ca...
