Cable branching device with efficient heat dissipation function

Abstract

The invention discloses a cable branching device with an efficient heat dissipation function, and belongs to the technical field of cable accessories, the cable branching device comprises a box body, a net plate and a heat dissipation plate are arranged in the box body, the net plate is connected with the heat dissipation plate, two ventilation mechanisms are arranged on the box body, and the heat dissipation plate is connected with the two ventilation mechanisms. An outer measuring plate and an inner measuring plate are arranged at the upper end and the lower end of each ventilation mechanism on the box body, two semiconductors are arranged between the outer measuring plates and the inner measuring plates, one of the semiconductors is electrically connected with the ventilation mechanism, and the ventilation mechanism controls the opening degree of the ventilation opening according to the voltage difference between the two semiconductors. The outer measuring plate measures the temperature inside and outside the box body, the inner measuring plate measures the temperature inside the box body, the two semiconductors are connected with the outer measuring plate and the inner measuring plate, the temperature difference between the outer measuring plate and the inner measuring plate enables the two semiconductors to generate voltage difference, namely current, and the ventilation mechanism comprises a piezoelectric material which deforms after being powered on. And opening and closing of the ventilation opening are changed.

Description

technical field [0001] The invention relates to the technical field of cable accessories, in particular to a cable branching device with an efficient heat dissipation function. Background technique [0002] The cable branch box plays the role of switching and branching cables. The main cable is used to go out. When it is close to the load, the main cable is divided into several branch cables by the cable branch box, and the small area branch cable is used to connect the load to the urban power grid. Such wiring methods are widely used in the power supply of street lamps and other small users. [0003] When each device is working, it will continuously dissipate heat inside the cable branch box. If the heat cannot be removed in time, it will seriously affect the work efficiency of the equipment. However, the heat dissipation function of the existing cable branch box is not good, and in the high temperature environment , it is very easy to cause the internal temperature of the...

[0003] When the equipment is working, it will continuously emit heat inside the cable branch box. If the heat cannot be removed in time, it will seriously affect the working efficiency of the equipment. However, the heat dissipation function of the existing cable branch box is not good. , it is very easy to cause the internal temperature of the cable branch box to be too high, the cable will be self-burned, and even cause a fire, causing a safety accident, which will threaten people's life and property safety
