Abstract

The utility model discloses a kind of Novel three-phase alternating-current catalyst, improve the manufacture structure of the prior art of traditional three-phase ac contactor main contacts, overcome existing traditional manufacture three-phase ac contactor, the main contacts used is too much, fault rate increases the deficiency in the technology such as maintenance and repair inconvenience, there is provided the main contacts of a kind of three-phase ac contactor only with three right, hinge structure reduces half main contacts, just can complete the simple in construction switched on and off with electrical equipment, firm and durable, lower-cost Novel three-phase alternating-current catalyst.

Description

Novel three-phase alternating-current catalyst

Technical field

The present invention relates to, industry, agricultural or automatic field control motor, or the operation of electrical equipment or The catalyst stopped.The present invention relates in particular, the main contact parts for three-phase ac contactor are changed The Novel three-phase alternating-current catalyst entered.

Background technology

At present, by people at industry agricultural and the widely used three-phase ac contactor of automatic field, mainly by Catalyst upper end is provided with the stationary contact of three groups of mutually insulateds, and lower end is provided with the stationary contact of three groups of mutually insulateds, upper end stationary contact With lower end stationary contact mutually insulated, upper end stationary contact connects with power supply, and lower end stationary contact connects with electrical equipment, two ends setting There is the armature contact of three groups of connecting plates of contact, driven by solenoid the three groups of activities being connected with solenoid plunger to touch Point, completes the connection with contact, top and bottom and disconnection, provides power work to electrical equipment, or deenergization stops work Make, owing to the rest(ing) contact used and armature contact are too much, six pairs of main contacts altogether, these six pairs of contacts connecting power supply when Must all contact good, electrical equipment could normally work, if wherein there being a conduction bad, will make electrical equipment not Can normally work, if two ends are provided with one end wherein burn of the armature contact of three groups of connecting plates of contact it is necessary to change One group is caused unnecessary waste, then has during the manufacturing of catalyst, and the ratio that the price of contact accounts for is quite big, mistake Many contacts that uses cause unnecessary economic loss to manufacturing producer and user.

Utility model content

The purpose of this utility model is, improves the manufacture knot of the prior art of traditional three-phase ac contactor main contacts Structure, overcomes existing traditional manufacture three-phase ac contactor, and the main contacts of employing is too much, relatively costly, fault rate increases maintenance With the deficiency repaired in the technology such as inconvenient, it is provided that the main contacts of a kind of three-phase ac contactor only with three right, the most existing skill Art reduces half main contacts, just can complete the simple in construction switched on and off with electrical equipment, firm and durable, lower-cost Novel three-phase alternating-current catalyst.

The purpose of this utility model is achieved by following technical proposals:

Novel three-phase alternating-current catalyst of the present utility model, including, shell body, upper cover, the electromagnetism within shell body Coil, static iron core, movable core, support spring, auxiliary contact, and the connecting plate two ends driven by movable core are provided with contact Main armature contact, and a sequence of top mutual with power supply binding post, the stationary main contact that top binding post is arranged, and Secure main rest(ing) contact and electrical equipment mutual a sequence of bottom binding post, the technical scheme is that, described quilt The one end of the connecting plate that movable core drives arranges main armature contact, touches with the static master of setting on described top binding post The most corresponding contact of point or disconnection, the other end arranges multiply soft copper wire or arranges elastic conduction copper coin and described bottom wiring Terminal is connected with each other.

Good effect of the present utility model is:

1. decrease the fault rate of main contacts；

2. maintenance and repair are simple and convenient；

3. it is readily produced producer's manufacture to change products, reduces manufacturing cost.

Accompanying drawing explanation

Fig. 1 is the structural representation of this utility model Novel three-phase alternating-current catalyst.

Detailed description of the invention

1 the utility model will be further described below in conjunction with the accompanying drawings.

In fig. 1,1 it is shell body, 2 is static iron core, 3 is movable core, 4 is integrally fixed at the electricity on static iron core 2 Magnetic coil, 5 be auxiliary contact, 6 be can be driven by movable core 3 main armature contact, 7 be bottom binding post, 11 be on The main rest(ing) contact in portion, 8 be top binding post, 9 be support the support spring of movable core 3,10 be to connect bottom binding post 7 Multiply soft copper wire or elastic conduction copper coin, one end of main armature contact 6 arranges contact, and the other end welds with multiply annealed copper wire 10 Connecing, or fasten with bolt, or use the resilient conductive copper plate one end of tool to arrange contact, the other end is direct with bottom binding post Fix with bolt.

Improved Novel three-phase alternating-current catalyst, service behaviour is just the same compared with existing traditional catalyst, And saving substantial amounts of manufacturing cost, performance is more stable, more easily maintenance and repair.

Claims

1. a Novel three-phase alternating-current catalyst, including, shell body, upper cover, the solenoid within shell body, static ferrum Core, movable core, support spring, auxiliary contact, and the connecting plate two ends driven by movable core be provided with the main activity of contact and touch Point, and a sequence of top mutual with power supply binding post, the stationary main contact that top binding post is arranged, and secure main quiet Only contact and electrical equipment mutual a sequence of bottom binding post, is characterized in that, the described connecting plate driven by movable core One end main armature contact is set, with on described top binding post arrange stationary main contact the most corresponding contact or break Opening, the other end arranges multiply soft copper wire or arranges elastic conduction copper coin and be connected with each other with described bottom binding post.
