The invention relates to the technical field of relay protection covers, in particular to a relay protection dustproof mistaken touch prevention heat dissipation cover, and aims to solve the technical problems that part of existing relay protection covers are difficult to effectively prevent dust, part of existing relay protective covers are inconvenient to disassemble, and part of existing relay protective covers do not have a mistaken touch prevention function. In order to solve the technical problem, the relay protection dustproof mistaken touch prevention heat dissipation cover provided by the invention comprises a base, wherein a relay main body is fixedly connected to the middle position of the top of the base. According to the invention, the relay protection dustproof mistaken touch prevention heat dissipation cover is composed of a heat dissipation and dust prevention mechanism, a mistaken touch prevention mechanism and a mounting mechanism, when the temperature in a protective cover rises, an expansion airbag is heated to expand and ejects a sliding rod upwards, at the moment, a connecting rod abuts against a hinged baffle to deflect, high-temperature gas in the protective cover is exhausted, and when the temperature in the protective cover drops, the expansion airbag shrinks, and the sliding rod drives the baffle to reset so as to seal and prevent dust on the side wall of the protective cover.
Description
technical field [0001] The invention relates to the field of relay protection covers, in particular to a relay protection dust-proof and false-touch heat dissipation cover. Background technique [0002] The relay is an electrical control device, which is an electrical appliance that causes the controlled quantity to undergo a predetermined step change in the electrical output circuit when the change of the input quantity meets the specified requirements. The relay is usually composed of a base and a cover. [0003] Some existing relay protective covers only dissipate heat from the relay through the slots on the surface of the protective cover, but during long-term use, dust can easily enter the interior of the relay through the slots, which affects the service life of the relay; some existing relay protective covers usually use plastic cards The buckle is connected to the base by clamping, but excessive force during the disassembly process may easily cause the plastic buckle...
