Description

A kind of relay of easy access

Technical field

The utility model belongs to relay technical field, and in particular to a kind of relay of easy access.

Background technology

The bimetal leaf that Double-metal-sheet type thermal over-loading relay is used is the sheet metal with two kinds of different linear expansion coefficients, is led to Cross what mechanically rolling was made together, one end is fixed, the other end is free end.When the temperature rise of bimetal leaf, due to two The linear expansion coefficient for planting metal is different, so it will bending.Thermal element is serially connected in motor stator winding, motor winding electricity Stream is the electric current for flowing through thermal element.When motor is normally run, though the heat that thermal element is produced can bend bimetal leaf, But it is insufficient to allow the actuating of relay;When electromotor overload, the heat increase that thermal element is produced makes bimetal leaf bending displacement amount Increase, through after a period of time, bimetal leaf bending promotes guide plate, and is separated contact with push rod by compensating bimetal leaf, Contact be electrothermal relay string in making contactor dead electricity after the break contact in contactor coil loop, disconnection, the dynamic circuit connector of contactor is touched Point disconnection motor even load loop, protects motor even load.

Relay when mounted, due to limited in space, while relay surface is smooth, pulls out dynamic into extraction making It is relatively elaborate when making, install trouble, be not easy to maintenance replace, also, numerous relay groups into relay group when, it is a certain When individual relay goes wrong, it is impossible to being checked come the problem of repairing quickly, service efficiency is reduced.

Utility model content

The purpose of this utility model is to provide a kind of relay of easy access, to solve to propose in above-mentioned background technology The problem of.

To achieve the above object, the utility model provides following technical scheme：A kind of relay of easy access, including push away Bar and support member, the top of the push rod are welded with bimetal leaf, and the middle part of the push rod is welded with joint, the joint It is embedded in by aperture on shell, the top of the support member is welded with compensation bimetal leaf, the right side of the compensation bimetal leaf End abuts in the left end of guide plate, and the lower surface of the guide plate is welded with thermal element by projecting point, the compensation bimetal leaf Left end is welded and fixed pusher, and the end of the pusher abuts the first stationary contact for movable contact described in movable contact, described Pusher is fixedly connected on pedestal by stage clip, and the side of the support member is welded with adjusting knob, and the shell passes through Aperture is removably connected with reset screw, and the end of the reset screw is the second stationary contact, and the shell is removable by aperture Unload and be connected with button, the one side of the shell opens up fluted, and the groove is welded with grid.

It is preferred that, the bimetal leaf is the different sheet metal of the linear expansion coefficient being pressed into, and removes fixing end, another Hold as free end.

It is preferred that, adjusting knob is an eccentric wheel.

It is preferred that, the stage clip, support member and adjusting knob constitute a lever.

It is preferred that, the joint is connected with terminal simultaneously.

It is preferred that, there are anti-slip veins the outer surface of the shell.

Technique effect of the present utility model and advantage：The relay of the easy access, when electromotor overload, thermal element production Raw heat increase, increases bimetal leaf bending displacement amount, after certain time, and bimetal leaf bending promotes guide plate, and Make contact with separating by compensating bimetal leaf and push rod, contact and be electrothermal relay be serially connected in contactor coil circuit one To break contact, break contact powers off contactor after disconnecting, and the moving together contact of contactor disconnects motor load circuit, protection Motor even load, when sound contact disconnects, terminal can be quickly it is accurate find out specifically which after Electrical equipment goes wrong, and substantially increases the convenience and efficiency of maintenance, meanwhile, the anti-slip veins of shell increase frictional force so that Maintenance personal more facilitates when relay is taken out.The relay of the easy access, overload protection ability is strong, repair and maintenance Convenience and high-efficiency, practicality is stronger.
