Description

A kind of D.C. contactor with auxiliary contact
Technical field
The present invention relates to a kind of D.C. contactors, more particularly to a kind of D.C. contactor with auxiliary contact.
Background technique
Contactor is a kind of automation control electric appliance, it is to flow through current induced magnetic field using coil, makes contact closure, To reach the electric appliance of control load.
D.C. contactor is generally included for connecting load to realize main contacts (including the master for carrying out on-off control to load Movable contact and main stationary contact), wherein main stationary contact is installed on main exit, active contact is to be located on dynamic spring and be mounted on to push away On motivation structure, when coil stimulating, pushing mechanism drives dynamic spring movement, makes active contact and main stationary contact point contact.The prior art This D.C. contactor in order to detect the break-make situation of main contacts, be usually installed with a microswitch, microswitch is Corresponding position in D.C. contactor is then equipped with a toggle arm on pushing mechanism, when pushing mechanism drives dynamic spring movement When making active contact and main stationary contact point contact, pushing mechanism drives toggle arm to move simultaneously, touches microswitch by toggle arm Swing arm, be switched on or switched off microswitch, signal be switched on or switched off to microswitch by the circuit board of D.C. contactor Detection, to realize the detection to main contacts break-make situation.This of the prior art realizes auxiliary contact function using microswitch The D.C. contactor of energy is primarily present as following drawbacks:
1, the function of auxiliary contact is realized by pushing mechanism and microswitch, too complicated in structure, reliability is relatively Difference;
2, need to be mounted so that microswitch, product can only use plastic package structure, so that it is specified negative to be only applicable to main contacts It carries lower;
3, the parameter of auxiliary contact is limited by microswitch;
4, microswitch needs external buying.
Summary of the invention
It is an object of the invention to overcome the deficiency of the prior art, provides a kind of D.C. contactor with auxiliary contact, leads to Cross and original microswitch be changed to the auxiliary contact structure pushed directly on by pushing mechanism, have structure simple, high reliablity, The characteristics of main contacts load is higher and can be designed a variety of loadtypes and contact types.
The technical solution adopted by the present invention to solve the technical problems is: a kind of D.C. contactor with auxiliary contact, packet Include pushing mechanism, the active spring with double active contacts and two are each configured with the main exit of main stationary contact, the active Spring is mounted on pushing mechanism to make active contact and main stationary contact point contact when pushing mechanism acts or separate;The direct current connects Tentaculum further includes the auxiliary exit that auxiliary stationary contact is each configured with the dynamic spring of auxiliary of double auxiliary movable contacts and at least two, It is described that dynamic spring is assisted to be also mounted on pushing mechanism, and pushing mechanism is made also to make that movable contact is assisted to connect with stationary contact is assisted when acting Touching or separation.
It is set as normally opened structure between the active contact and main stationary contact, when pushing mechanism movement keeps active contact and master quiet When contact contacts, the pushing mechanism also makes that movable contact is assisted stationary contact point contact or to separate with auxiliary when acting.
The auxiliary exit is four, and two of them auxiliary exit is set as assisting normally opened exit, other two is auxiliary Exit is helped to be set as assisting normally closed exit, two normally opened exits of auxiliary, which are separately positioned on to correspond to, assists the auxiliary of dynamic spring dynamic At the position of contact, and the position is on the moving direction that pushing mechanism contacts main contacts.
The auxiliary exit is two, this two auxiliary exits are set as assisting normally opened exit, and two auxiliary are normally opened Exit is separately positioned at the position for corresponding to the auxiliary movable contact for assisting dynamic spring, and the position is to make main touching in pushing mechanism On the moving direction of point contact.
The auxiliary exit is two, this two auxiliary exits are set as assisting normally closed exit, and two auxiliary are normally closed Exit is separately positioned at the position for corresponding to the auxiliary movable contact for assisting dynamic spring, and the position is to make main touching in pushing mechanism On the isolated moving direction of point.
The D.C. contactor further includes housing, and the main exit and the normally opened exit of auxiliary are separately mounted to housing On, so that active contact, main stationary contact, auxiliary movable contact and auxiliary stationary contact is all contained in the intracavitary of housing.
The housing is equipped with step, and the main exit and the normally opened exit of auxiliary are separately mounted to the upper and lower platform of housing At rank, to make the cooperation position of active contact and main stationary contact, auxiliary movable contact and the cooperation position of stationary contact is assisted to distinguish It is in the space separated by step.
The housing is ceramic housing.
The active spring and the dynamic spring of auxiliary are "-" type structure, and active spring and the dynamic projection of spring in the plane of auxiliary are big It causes in vertical state.
The pushing mechanism includes pushing seat, catch bar and U-shaped basket, and described one end for pushing seat to be fixed on catch bar is U-shaped Basket, which is mounted on, to be pushed on seat, and described that dynamic spring is assisted to be fixed on promotion seat, the active spring is mounted on U-shaped basket by contact spring Interior, against active spring, the other end, which is against, to be pushed on seat for one end of contact spring.
It is described to assist moving spring being flexible flake structure, to utilize the flexible deformation realization auxiliary contact for assisting dynamic spring Overtravel.
Compared with prior art, the beneficial effects of the present invention are:
1, of the invention due to using the dynamic spring of auxiliary being additionally provided in D.C. contactor with double auxiliary movable contacts and extremely Few two are each configured with the auxiliary exit of auxiliary stationary contact, assist dynamic spring to be also mounted on pushing mechanism, and make pushing mechanism Also make to assist when movement movable contact with assist stationary contact point contact or separating, the present invention is to increase auxiliary directly on pushing mechanism to move Spring, then increase by one group or two groups of auxiliary stationary contacts on exit, it realizes the function of one group or two groups auxiliary contact, is compared to Original microswitch mode has the characteristics that structure is simpler, reliability is higher.
2, this structure of the invention can be designed the auxiliary contact of a variety of loadtypes and contact types, can use one The normally opened auxiliary contact of group or normally closed auxiliary contact realize the function of Simultaneous Monitoring main contacts on-off, also can use one group it is normally opened auxiliary It helps contact or normally closed auxiliary contact to realize other circuit functions, such as power saving function etc., can also be touched respectively using two groups of auxiliary Point (one group of normally opened auxiliary contact and one group of normally closed auxiliary contact) carrys out while realizing Simultaneous Monitoring main contacts on-off and its realizes electricity Normally opened one end and normally closed one end in auxiliary exit can also be linked together, form conversion by the functions such as road energy conservation Auxiliary contact.
3, this scheme of the invention can either use plastic package structure, to be adapted to make when main contacts nominal load is lower With;Ceramic structure can be used again, by auxiliary contact and main contacts all welded seals in ceramic cavity, to be adapted to main contacts It is used when loading higher.
Invention is further described in detail with reference to the accompanying drawings and embodiments;But a kind of band auxiliary contact of the invention D.C. contactor be not limited to the embodiment.
