Abstract
The utility model provides a double entry contactor in the contactor casing, installs quiet iron core, solenoid, reset spring, it fixes on moving the iron core to link up the frame, link up the operation movable contact spring pressure spring that put up, operation movable contact spring bullet spring frame, arc extinction movable contact spring pressure spring, arc extinction movable contact spring bullet spring frame and operation movable contact spring and the linking of arc extinction movable contact spring, the operation movable contact spring is equipped with the operation movable contact, the arc extinction movable contact spring is equipped with the arc extinction movable contact, install fixed contact piece in the casing inside groove, fixed contact piece is equipped with arc extinction stationary contact, operation stationary contact and binding post. The advantage is during the contact of operation contact, no longer to produce electric arc to protect the smoothness of operation contact contact surface, reduced contact resistance, reduced and generated heat, improved the conductivity, increased the life of contactor, also protected electrical equipment's safety, normal operating simultaneously.
Description
Technical field
This utility model is a kind of compound catalyst of dual main contacts.
Background technology
In existing catalyst, it is monolayer main contacts, in actually used operation, electricity given by catalyst, and main contacts is just
Moment before contact or after disconnecting, electric arc, high temperature will be produced, contact will melt bead, pitting, uneven, touch
Point loose contact, contact resistance increase, run in increase caloric value, then strike sparks, or even burn out.Thus, also burn out motor,
The phenomenon of electrical equipment.
Content of the invention:
The purpose of this utility model is, solves above-mentioned existing problem, provides a kind of the compound of dual main contacts
Catalyst.
Basis is practical to be achieved in that in catalyst housing, is provided with static iron core, solenoid, back-moving spring；Rank
Connect frame to be fixed in dynamic iron core；Cohesive frame passes through to run movable contact spring holddown spring, runs movable contact spring spring(-supported) mount, extinguishing arc movable contact spring pressure
Tight spring, extinguishing arc movable contact spring spring(-supported) mount are connected with operation movable contact spring and extinguishing arc movable contact spring；Run movable contact spring and be provided with operation movable contact；
Extinguishing arc movable contact spring is provided with extinguishing arc movable contact；Fixed touching plate is installed in housing inside groove, fixed touching plate is provided with extinguishing arc stationary contact, runs stationary contact
Point and binding post.
The utility model has the advantages that, compound catalyst has two groups of contacts, and one group is extinguishing arc contact, contacts for, mainly
For extinguishing arc and switch on power with load；Another group is to run contact, is face contact, and main guarantee electrical equipment normally runs；Fortune
During row contact, no longer produce electric arc, thus protect running the smooth of contact face, decreasing contact resistance, reducing
Heating, improves conductivity, increased the service life of catalyst, also protect safe, the normal fortune of electrical equipment simultaneously
OK.
Brief description
Fig. 1 is structural representation of the present utility model；
Fig. 2 is left view.
Specific embodiment
Below in conjunction with the accompanying drawings describe in detail: as shown, in catalyst housing 1, be provided with static iron core 2, solenoid 3,
Back-moving spring 4；Cohesive frame 13 is fixed in dynamic iron core 5；Cohesive frame 13 passes through to run movable contact spring holddown spring 12, runs movable contact spring
Spring(-supported) mount 11, extinguishing arc movable contact spring holddown spring 10, extinguishing arc movable contact spring spring(-supported) mount 9 are held in the mouth with operation movable contact spring 8 and extinguishing arc movable contact spring 7
Connect.Run movable contact spring 8 and be provided with operation movable contact 8a；Extinguishing arc movable contact spring 7 is provided with extinguishing arc movable contact 7a；Housing 1 inside groove is installed
Fixed touching plate 6, fixed touching plate 6 is provided with extinguishing arc stationary contact 6a, runs stationary contact 6b and binding post 6c.
Its operation principle is:
This utility model is installed in circuit, binding post 6c is connected on power supply and load respectively, during work, electromagnetic coil
3 electric, static iron core 2 is magnetized, and produces magnetic force, attracts dynamic iron core 5, drives cohesive frame 13, affect extinguishing arc movable contact spring 7, run dynamic
Contact 8, makes extinguishing arc movable contact 7a, stationary contact 6b is quickly close to extinguishing arc stationary contact 6a, operation respectively to run movable contact 8a.Because
Being smaller than of the dynamic and static contact of extinguishing arc runs the spacing of dynamic and static contact, so, the dynamic and static contact of extinguishing arc first contacts, before contact
Moment produce electric arc, strike sparks, connect real, compression；Therewith, run dynamic and static contact and connect real, compression；Due to power supply with load by
Extinguishing arc contacting, so, when running contact, just no longer produce electric arc, thus protect running contact face
Smooth it is ensured that their contact well, makes electric current normally circulate, contact resistance reduces, and reduces heating, extends catalyst
Service life, has ensured the good operation of electrical equipment.
