Description

Cable connector with waterproof heat dissipation function

The invention belongs to the application date: 2019-12-16, application number: 201911361367.5, patent name: a divisional application of a cable joint with waterproof and heat-dissipating functions is provided.

Technical Field

The invention belongs to the technical field of cable connectors, relates to a cable connector, and particularly relates to a cable connector with waterproof and heat dissipation functions.

Background

The cable connector is also called a cable head. After the cable is laid, the sections of the cable must be connected together in order to form a continuous line, and these connections are called cable connectors. The cable joints at the middle of the cable run are called intermediate joints and the cable joints at the two ends of the run are called termination joints. The cable joint is used for locking and fixing the incoming and outgoing lines, and plays a role in water resistance, dust prevention and vibration prevention.

Some electrical installation operators often do not notice the quality of the installation when laying the wires: the insulating sleeve is not installed at the position where the insulating sleeve is used; the junction box is not arranged at the place where the junction box is needed, and the junction box continuously generates heat when being electrified, so that the nearby wood boards are gradually dried and carbonized, and finally, the wood boards are burnt to cause fire.

The heating of the wire connector not only causes a large amount of electric energy loss, but also seriously affects the normal work of the electrical equipment, so that the working current in the line is increased, the service life of the electrical equipment is shortened, the ongoing production, scientific research, medical operation and other activities are suddenly interrupted, and fire, electric shock accidents and the like are caused, thereby causing loss which is difficult to estimate.

The existing cable joint is mostly formed by combining and fixing joint components made of metal, when the cable works, the generated temperature rise is large, heat is accumulated in the cable joint, the heat dissipation efficiency of the cable joint is low, the internal air pressure of the cable joint is increased due to high heat accumulation, voltage difference in the cable is easy to break down, and a sealing rubber ring arranged between the cable joint and the cable is softened or even melted, so that the waterproof performance of the cable joint is reduced, and the normal work of an image cable is realized.
