Abstract
An electronic magnetic force control contactor of the utility model relates to the controller field, and is composed of a cylindrical shell and a shell cover body. A coil support is arranged inside the cylindrical shell, and a movable iron core is arranged at the lower part inside the coil support. The bottom end of the movable iron core is connected with a handle outside the cylindrical shell via a pull rod, and a reset spring I is arranged between the top end of the movable iron core and a fixing base. A transmission rod is arranged at the axis of the fixing base slidably, a screw at the upper part of the transmission rod is connected with a movable contact disc, and more than two sliding limiting rods are arranged on the end face at the lower part of the movable iron core to support the use of the sliding jacks on the fixing base. The electronic magnetic force control contactor of the utility model is simple in structure and low in cost, is time-saving and labor-saving to disassemble and install, and enables the friction between the movable iron core and the coil support to be reduced effectively, the overall service life and maintenance frequency to be prolonged and the cost and workload of the maintenance personnel to be reduced.
Description
Technical field
The utility model relates to controller field, especially relates to a kind of electronic magnetic control contactor.
Background technology
Electronic magnetic control contactor is widely used in various fields as a kind of important form of switch.Existing electronic magnetic control contactor exists some problems, for example mechanical friction larger, movement response is slow, thereby large its Performance Ratio of its power consumption is lower, detachable maintaining inconvenience etc., simultaneously, moving iron core in existing electronic magnetic control contactor is placed in coil brace inside, except having back-moving spring, without any support, make moving iron core unstable in coil brace, cause between moving iron core periphery and coil brace inwall and produce friction increase, the fluency, useful life and the power consumption that affect contactor entirety are large, have shortened maintenance cycle.Connected mode between existing control contactor shell is unreasonable again, very inconvenient in the time of repair demolition, as switch housing in the application that Chinese Patent Application No. is 2010201536530, patent name is electromagnetic switch is provided with switch cover combination, shown in its accompanying drawing, the two is interference connection, although this connected mode good sealing effect, but be unfavorable for dismounting and install, can not take out from shell for the maintenance in later stage brings certain difficulty, especially inner coil brace, in the time that coil goes wrong, just can not solve by maintenance.
Utility model content
The utility model is intended to for the deficiency existing in background technology, and the electronic magnetic control contactor proposing.
Electronic magnetic control contactor of the present utility model, to be formed by cylindrical case and shell cover, between its cylindrical case and shell cover, accompany holder, and by plural bolt, its three partial fixing is connected, cylindrical case inside is equipped with coil brace, coil brace periphery is wound with coil, bottom in coil brace is equipped with moving iron core, the bottom of moving iron core is connected with the handle in cylindrical case outside by pull bar, between the top of moving iron core and holder, back-moving spring I is installed, the axle center place of the holder drive link that is being slidably installed, drive link top screw socket is connecting movable contact dish, the inside of shell cover is provided with two fixed contacts and is fixedly connected with outside stationary contact headpin, between described movable contact dish and shell cover, back-moving spring II is installed, the slip jack being installed with on plural slip gag lever post and holder on described moving mandrel lower end face is used in conjunction with.
As further improvement of the utility model, described gag lever post screw socket is fixed on the upper surface of moving iron core, and is non-conductive material.
As further improvement of the utility model, the tail end of described pull bar slides and is placed among moving core interior, and on the pull bar being placed in moving iron core, spring is installed.
As further improvement of the utility model, described handle is connected with pull bar screw socket.
Electronic magnetic control contactor of the present utility model, simple in structure, cost is low, it is time saving and energy saving to dismantle and install, the design of gag lever post makes moving iron core stable in coil brace, effectively reduce friction between moving iron core and coil brace, energy-conservation, extend overall useful life and frequency of maintenance, reduced cost and maintenance personal's the amount of labour.
