Problems solved by technology

[0004] Some of the prior art relays are connected by sealing glue between the bottom plate and the outer shell, which will cause the bottom plate to fall off after long-term use, and the cost of the glue is relatively high; or some are welded, and the relay needs to be sealed during use. For repair and replacement, welding will cause high cost of repair and replacement, laborious disassembly

Abstract

The invention provides a clamping fixation type relay, and belongs to the technical field of electrical equipment. The clamping fixation type relay solves the problem that connection of an existing relay is unstable. The clamping fixation type relay comprises a base plate, an outer shell and a control assembly. The control assembly comprises a control panel and a plurality of control coils, wherein the control panel is arranged on the top of the outer shell in a clamping mode, and the control coils are installed in the outer shell. The base plate is arranged at the bottom of the outer shell in a buckling mode through a buckling structure; the outer shell is made of composite resin which is formed by reasonable combination of PC, PET, carbon fibers, titanium dioxide, nano calcium carbonate, flexibilizer, compatibilizer and processing agents; the buckling structure comprises a locking part and a locating part; the locking part comprises a plurality of clamping hooks and a plurality of clamping grooves, wherein the clamping hooks are fixedly connected to the base plate, and the clamping grooves and the clamping hooks are in one-to-one correspondence, and the clamping hooks are clamped in the clamping grooves; the locating part comprises a plurality of locating protruding blocks and a plurality of locating grooves, wherein the locating protruding blocks are arranged on the base plate, and the locating grooves and the locating protruding blocks are in one-to-one correspondence, and the locating protruding blocks are matched with the locating grooves. The clamping fixation type relay is simple in structure, good in connection stability and long in service life and convenient to disassemble.

Description

technical field [0001] The invention belongs to the technical field of electrical equipment, and relates to a clamping relay. Background technique [0002] The relay is an automatic control device whose output will change in a jump when the input quantity (electricity, magnetism, sound, light, heat, also known as excitation quantity) reaches a certain value. , is an electronic control device, it has a control system (also known as the input circuit) and a controlled system (also known as the output circuit), usually used in automatic control circuits, it actually uses a smaller current to control a larger An "automatic switch" of electric current. It plays the role of automatic adjustment, safety protection, conversion circuit and so on in the circuit. [0003] The electromagnetic relay is mainly composed of an input part and an output part. These two parts mainly include: the coil at the input end, the yoke iron, the isolation plate, the bottom plate, the iron core, the ...
