Description

Energy-saving soundless A.C, D.C. contactor

A kind of energy-saving, noiseless AC/DC contactor belongs to the electric switch technical field, is mainly used in the power supply that is switched on or switched off with electric line.

Mostly AC/DC contactor commonly used is to get and make iron core magnetization adhesive after electric by pressing the button iron-core coil in prior art, drives the node conducting and send electricity to power consumption equipment, presses the power failure button when stopping and making the iron-core coil outage, the node disconnection.Send in the whole process of electricity iron-core coil to switch on all the time to power consumption equipment like this, the own power consumption of contactor and produce noise.Contactor is a kind of important electric switch that often uses in the various power consumption equipments.In order to economize on electricity and to optimize operational environment, must put into the melting pot it.

It is a kind of simple in structure that the purpose of this utility model is to provide, reasonable in design, make easily, only when being switched on or switched off, use seldom, can send electricity to power consumption equipment by mechanical lock buckle entirely later on, can save energy and do not produce the energy-saving, noiseless AC/DC contactor of noise.

According to the electric switch basic principle, at the subject matter that exists in the prior art, basic design of the present utility model is: on the basis of former electromagnetic treadle, utilize the mechanical lock buckle closure, replace energising magnetic field closure, other adds one group of less electromagnetic core coil and does and open mechanical lock buckle usefulness, makes former electromagnetic core coil only do usefulness when starting, thereby realizes the purpose that economize on electricity is noiseless.

Of the present utility model be characterised in that described energy-saving, noiseless AC/DC contactor keep original on, lower core, on the basis of iron-core coil and upper core axillare, again by the snap close newel, clinching, the snap close back-moving spring, open iron core clinching iron that mechanical lock buckle uses and on, lower core and iron core loose-leaf and coil constitute, above-mentioned upper core axillare be on the basis of original this axillare the lengthening and with a barb-shaped box that is connected with above-mentioned clinching buckle, so that live with above-mentioned clinching snap close after unclamping start button during energized, make iron core still be in attracting state under the situation of dead electricity, this iron core axillare is fixedlyed connected with above-mentioned former upper core and can be with this upper core synchronous interface; Above-mentioned clinching is installed on the upper side end of above-mentioned former lower core by above-mentioned snap close newel, and can rotate around this newel under the effect of above-mentioned snap close back-moving spring; Above-mentioned snap close back-moving spring lower end is fixed in the location hole of the spring; Above-mentioned iron core clinching iron one end is vertical with above-mentioned clinching to press flexible connection, and other end curved boom is opened the upper core that mechanical lock buckle uses and fixedlyed connected with above-mentioned; It is above-mentioned that to open upper and lower two iron cores that mechanical lock buckle uses hinged by above-mentioned iron core loose-leaf; Above-mentioned former lower core and open lower core that mechanical lock buckle uses the two is what be connected as a single entity, promptly the two is that " mountain " font opening direction of their suit iron-core coils is mutually 90 ° by the moulding of same iron core sheet material time processing.

Outstanding advantage of the present utility model is: this contactor construction is simple, processing and fabricating, it is all convenient to install and use, on, the required precision of two groups of iron core contact-making surfaces is not high down, both can be used for direct current, can be used for again exchanging, original iron-core coil only leads to about 1 second when energising starts, only lean on the effect of mechanical lock buckle to make iron core safeguard attracting state and no longer power consumption later on, only need make during outage and open the less iron-core coil energising that mechanical lock buckle is used, make iron core Attraction strap dynamic pressure button iron, open snap close and get final product, therefore can save electric energy greatly, also do not produce noise simultaneously.

Accompanying drawing is one of a utility model most preferred embodiment schematic side view; Upper core axillare among the figure behind 1 lengthening, 2 former upper cores, 3 snap close newels, 4 clinchings, 5 iron core clinching iron, 6 open the upper core that mechanical lock buckle is used, 7 iron core loose-leaves, 8 open the coil that mechanical lock buckle is used, 9 snap close back-moving springs, 10 former iron-core coils, 11 former lower cores, 12 location hole of the spring, 13 and former lower core 11 be connected as a single entity open the lower core that mechanical lock buckle is used.

In conjunction with the accompanying drawings the utility model course of action is summarized as follows: press start button, former upper core 2 drives node closure, power connection, simultaneously on the axillare 1 with box press down, clinching 4 is pushed up to limit,, pin box because the effect of snap close back-moving spring 9 resets clinching 4; Unclamp start button, former iron-core coil 10 dead electricity, but because of snap action, former upper and lower iron core 2 and 11 is still located attracting state, contactor work; Press stop button during power failure, coil 8 electric, upper and lower iron core 6 and 13 adhesives drive 5 motions of clinching iron and open snap close, former upper core 2 resets and drives node and be in off-state, contactor quits work.

Institute cored 2 and 11,6 and 13 all adopts known silicon steel sheet punch forming, former upper core 2, length * wide=95 * 25(mm in this embodiment ²), former lower core 11, length * wide=95 * 63(mm ²), open the upper core 6 that mechanical lock buckle is used, length * wide=52 * 20(mm ²), lower core 13, length * wide=52 * 23(mm ²), two lower cores 11 and 13 are one time punching molded, and " mountain " font opening is mutually 90 °; Former iron-core coil 10, the enameled wire loop of selecting for use known 60A contactor to use; Open the iron-core coil 8 that mechanical lock buckle is used, the enamelled wire that adopts φ 0.14mm is around 4250 circles, and square hole 13 * 11(mm) in the circle is used for the 220V power supply; The thick sheet metal of iron core axillare 1 usefulness 2mm strikes out channel-section steel, and overall dimensions and former upper core 2 adapt, and only upper end lengthening and bending are 90 °, and end is with a barb box; Clinching 4 adopts the thick band steel of 5mm to be processed into the projection that approximate " f " shape and an end band fixing spring are used, length overall 40mm; The thick steel plate of iron core clinching iron 5 usefulness 2mm be processed into "

" shape, curved boom is a channel-section steel on it, respectively with clinching 4 and open the upper core 6 that mechanical lock buckle uses and press and rivet, spring 9 is selected φ 6mm wire spring, long 20mm for use.

Change as present embodiment:

1, the connected mode of clinching 4 and former lower core 2 can change into lower core 2 sides add in addition a steel plate make the dress newel 3 the hole move to outside the iron core;

2, opening upper and lower two iron cores that mechanical lock buckle uses can use pin instead and be connected with pressure hook;

3, used raw material of each iron core and coil and overall dimensions around the number of turns can suitably change according to the circuit that is suitable for.
