Description

Contactor

Technical field

The utility model relates to Low Voltage Electrical Apparatus, particularly a kind of contactor.

Background technology

A.C. contactor is a kind of electrical equipment for remote frequent connection and point deenergizing, mainly contains base,Be placed in the pedestal on base and be installed on base and pedestal between coil composition.

Coil is as the important component part of the electromagnetic system of contactor, and its quality directly affects electric propertyIndex and functional reliability. Existing to enamel-covered wire protectiveness, insulating properties deficiency, easily cause inside and outside lead-out wireThe paint film of enamel-covered wire is easily scraped, and causes coil occur short circuit or open circuit; Some external lead-out wire adopts coverPipe increases protection and insulating properties, has increased material and winding process.

Coil rack is as the important spare part of contactor product, by heat-resisting, wear-resisting, are-tight and impact strengthHigh thermoplastic is made, and the coil that coil rack is contactor provides matrix. Existing coil rack and baseBetween seat and base, do not have spacingly, product can move up and down in working order, causes coil concussion, acceleratesCoil rack distortion and coil are aging; Product can move forward and backward in the time of assembling, causes assembling difficulty, reduces rawProduce efficiency.

The contact support of existing contactor is as the important structure part of supports contacts, by heat-resisting, wear-resisting, are-tightAnd the high solidity plastics of impact strength are made. Touch spring, for contact provides contact pressure, ensures that contact is reliableContact. The guiding that the assembling of existing touch spring is not installed, installation effectiveness is lower.

The galvanic circle of contactor is mainly made up of the conducting element such as static contact and contact bridge, the closure of contact andIn breaking course, require contact that melting welding does not occur, and wearing and tearing are as much as possible little. Long-term use procedure has necessarilyTemperature rise, require contact resistance stable. Contact can produce electric arc in disjunction circuitry processes, and electric arc is followedHigh-energy can cause contact melting welding. The effect of arc extinction part is exactly to extinguish the electric arc producing in contact breaking course.The installation site of contact and arc extinction part is accurate and firmly most important, has influence on contact and the contact resistance of contactSize, to contact normal work extremely important. Existing contact location is to slot in base wall, can onlyContact is carried out spacing, and arc extinction part can only rely on the wall of pedestal as spacing, and spacing deficiency, arc extinction partEasily rock. And contact heating easily causes the distortion of base wall, thereby makes arc extinction part spacing unreliable.

In addition, base is as the major part of contact support member, and the mounting characteristic of contactor is all also at baseUpper, in transportation, base is also a very crackly part, so that base needs is certain strongDegree and rigidity, vibration, impact etc. in carrying contactor work and transportation. Existing Foundation Plate of ContactorBottom surface impact resistance deficiency, in being subject to greater impact, in sidewall and the underside wall intersection of baseBe prone to cracking.
