Description

Technical Field

[0001] The utility model relates to the technical field of relays, in particular to a plug-in type automobile relay. Background Art

[0002] A relay is an automatic control device that will cause a jump in output when the input (electricity, magnetism, sound, light, heat) reaches a certain value. It is usually used in automated control circuits. It is actually an automatic switch that uses a small current to control a large current. Therefore, it plays the role of automatic regulation, safety protection, and circuit conversion in the circuit.

[0003] The utility model patent application document with publication number "CN204946818U" discloses an easily fixed automotive relay, which includes a housing, internal components, plug terminals, welding feet and dry bumps. This technical solution prevents the connection between the socket wire and the circuit board from loosening.

[0004] The easily fixed automobile relay disclosed in the above document has the following defects: the housing of the technical solution is easily damaged when impacted by external force, and it does not have a good waterproof sealing effect.

[0005] It can be seen from this that the existing easy-to-fix automobile relay does not have a protective housing and a waterproof sealing structure, and it is necessary to improve the existing deficiencies and provide a plug-in automobile relay. Summary of the invention

[0006] The purpose of the utility model is to provide a plug-in automobile relay to solve the problems raised in the above background technology.

[0009] Furthermore, a fixed structure is provided on one side of the reinforcement shell, and the fixed structure includes a fixed shell, a second spring, a fixed plate, an extension block, a mounting hole, a gasket and a first anti-slip groove; a fixed shell is fixedly installed on one side of the reinforcement shell, a second spring is fixedly installed inside the fixed shell, the number of the second springs is fixed to three, a fixed plate is fixedly installed on one end of the second spring, an extension block is movably installed on the inner wall of the fixed shell, the extension block is connected to the fixed plate, a mounting hole is opened on one end of the extension block, a gasket is fixedly installed on one end of the fixed shell, and a plurality of first anti-slip grooves are opened on one side of the mounting hole.

[0010] Furthermore, a circular plate is fixedly mounted on the front of the reinforcement shell, the number of the circular plates is fixed at two, and a plurality of second anti-slip grooves are provided on the front of the circular plates.

[0011] Furthermore, a mounting plate is fixedly mounted on one side of the reinforcement shell, and a plurality of heat dissipation fins are arranged on one side of the mounting plate.

[0012] Furthermore, a sealing ring is fixedly mounted on the lower surface of the shell, and the sealing ring abuts against the inner wall of the reinforcement shell.

[0013] Furthermore, a lead pin is fixedly mounted on the lower surface of the shell, the number of the lead pins is fixed to four, and a plurality of through slots are formed at one end of the lead pin.

[0014] The utility model has the following beneficial effects:

[0015] (1) The utility model aligns the installation structure provided inside the reinforcement shell with the slide groove and pushes it downward, and the card block squeezes the spring, so that the card block enters the interior of the sleeve shell. When it moves to the card groove, the card block pops out and enters the card groove, thereby installing the reinforcement shell. The reinforcement shell can be removed by pulling it outward with great force through the setting of the arc groove. The installation and disassembly are simple and convenient, and the shell can be protected, which greatly improves the practicality.

[0016] (2) The utility model can prevent water stains from entering the interior by abutting the inner wall of the reinforcement shell through the sealing ring, thereby protecting the internal components. The arrangement of the circular plate and the second anti-slip groove makes it more convenient to remove the reinforcement shell by leveraging force and saving effort. The heat dissipation fins can dissipate the internal components of the shell, thereby improving practicality.

[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
