Electrical sealing device for protecting electrical element

Abstract

The invention relates to the technical field of electrical elements, and discloses an electrical sealing device for protecting electrical elements, which comprises a sealing box body, and the outer wall of the sealing box body is movably provided with a box door. According to the heat dissipation device, when the heat dissipation fan runs, air and heat are blown out through heat dissipation holes in the two sides, a folding plate movably installed in a fixing frame is subjected to the outward wind action, the folding plate rotates in the outer side direction and is folded, a first spring is compressed at the moment, and when the wind force constantly changes, the wind force action borne by the folding plate constantly changes, so that the heat dissipation effect is achieved. A folding plate is continuously folded and rotated in the fixed frame under the action of wind power and the elastic force of a spring I, and when the folding plate is rotated and folded, acting force is applied to an impact block movably mounted in a sleeve; at the moment, the impact block drives the connecting block to slide and impact the surface of the dustproof net under the action of external force, so that dust and sundries adhered to the dustproof net fall off, and the problem that the heat dissipation effect is affected due to blockage of meshes of the dustproof net is solved.

Description

technical field [0001] The present invention relates to the technical field of electrical components, in particular to an electrical sealing device for protecting electrical components. Background technique [0002] Electronic components are the basic elements in electronic circuits, usually individual packages with two or more leads or metal contacts. Electronic components must be connected to each other to form an electronic circuit with a specific function, such as: amplifiers, radio receivers, oscillators, etc. One of the common ways to connect electronic components is to solder to a printed circuit board. Electronic components may be individual packages (resistors, capacitors, inductors, transistors, diodes, etc.), or groups of various complexities, such as integrated circuits (op amps, resistor exclusions, logic gates, etc.), for To maintain the stability of the operation of electronic components, they are usually encapsulated with synthetic resin to improve insulatio...

AI Technical Summary

Problems solved by technology

Electronic components may be individual packages (resistors, capacitors, inductors, transistors, diodes, etc.), or groups of varying complexity, such as integrated circuits (op amps, resistors, logic gates, etc.), for To maintain the stability of the operation of electronic components, they are usually encapsulated with synthetic resin to improve insulation and protection from environmental influences. When the electrical components are used outdoors, a sealing device is used to seal and protect the electrical components, and the electrical components A lot of heat will be generated during use and operation. Generally, in order to facilitate heat dissipation, cooling holes will be opened on the outer wall of the sealed box for heat dissipation. Dust is intercepted, and after long-term use of the dust-proof net, more dust and debris will adhere to its surface. At this time, the mesh holes of the dust-proof net may be blocked, which will affect the heat dissipation effect in the later stage.
