Problems solved by technology

However, no matter which method is used, the installation space must be reserved for each PTC circuit protection device
However, sometimes there are many cables and they are very dense, and the installation space becomes very tight at this time, and it is impossible to install multiple independent PTC circuit protection devices
At the same time, since the body of the PTC circuit protection device has a certain rigidity, when the PTC circuit protection device is located between the cables, the cable cannot be bent at the position where the PTC circuit protection device is located, which reduces the layout density of the cables.

Abstract

The invention discloses a cable. The cable comprises a first conductor, a second conductor and a PTC material layer, wherein the PTC material layer is directly combined with the first conductor and the second conductor, wherein the first conductor and the second conductor are isolated from each other and are mutually and electrically connected through the PTC material layer, so that current can flow between the first conductor and the second conductor through the PTC material layer. When the current flowing through the first conductor and the second conductor is overhigh, the temperature of the PTC material is raised and the PTC material is triggered to reach a high-resistance state so as to enable the current flowing through the first conductor and the second conductor to be rapidly lowered to below a normal current value. Therefore, the cable provided by the invention has a power transmission function as well as an overcurrent and overheat protection function.

Description

technical field [0001] The invention relates to a cable, a cable manufacturing method, a circuit protection device, a circuit protection device manufacturing method and a load circuit. Background technique [0002] In the prior art, a PTC (Positive Temperature Coefficient) circuit protection device is an independent electronic device, which only has over-current and / or over-voltage protection functions, and cannot be used for power transmission. Therefore, in the prior art, it is necessary to use wires separated from the PTC circuit protection device to implement power transmission between various electrical devices. [0003] In the prior art, the installation position of the PTC circuit protection device is usually on a function board or between cables. However, no matter which method is used, an installation location space must be reserved for each PTC circuit protection device. However, sometimes there are many cables and they are very dense, and the installation space ...
