Problems solved by technology
[0003] Existing relays include a shell and a bottom plate. The connection between the shell and the bottom plate is generally screwed or the shell and the bottom plate are fixedly connected with a sealant. The sealant is used to connect the shell and the bottom plate. The shell and the bottom plate cannot be disassembled, resulting in inability to maintain; while the shell and the bottom plate are connected by screws, it is troublesome to disassemble the shell and the bottom plate, and there is no complete seal between the shell and the bottom plate, which will be affected by external gas or water during use, affecting the relay performance

The invention belongs to the technical field of electronic control device, and specifically discloses a relay convenient for disassembling. The relay comprises a shell, a bottom plate, and a relay main body structure fixed on the surface of the bottom plate; the shell is buckled on the top of the bottom plate, wherein sliding chutes are opened on the left and right sides of the side wall of the bottom plate; a clamping strip is glidingly connected in the sliding chute; a first spring is connected between the clamping strip and the sliding chute; a pull rod is connected on the lower supper of the clamping strip; a through groove for moving the pull rod is opened on the bottom plate; bumps are arranged on the left and right sides of the lower part of the shell; a cavity clamped with the clamping strip is opened on the bump; a sliding block is glidingly connected in the cavity; a second spring is connected between the sliding block and the cavity; the contact part of the shell and the bottom plate is provided with an air bag; and an air pipe is connected between the air bag and the cavity. By adoption of the replay provided by the invention, the shell and the bottom plate can be rapidly disassembled; and thus, the relay is convenient to be maintained.
Description
technical field [0001] The invention belongs to the technical field of electronic control devices, in particular to a relay that is easy to disassemble. 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. It has an interactive relationship between the control system (also known as the input loop) and the controlled system (also known as the output loop). Usually used in automatic control circuits, it is actually an "automatic switch" that uses a small current to control the operation of a large current. Therefore, it plays the role of automatic adjustment, safety protection, and conversion circuit in the circuit. [0003] Existing relays include a shell and a bottom plate. The connection between the shell and the bottom plate is generally scre...
