Description
Technical field
This utility model relates to Low Voltage Electrical Apparatus, particularly to a kind of catalyst.
Background technology
A.C. contactor is a kind of mainly to have base for frequently switching at a distance and the electrical equipment of disjunction circuit, is placed in the pedestal on base and the coil composition being installed between base and pedestal.
Coil is as the important component part of the electromagnetic system of catalyst, and its quality directly affects electric property index and functional reliability.Existing to enamel-covered wire protectiveness, insulating properties deficiency, it is easy to cause the paint film of inside and outside lead-out wire enamel-covered wire to be easily scraped, cause that short circuit or open circuit occurs in coil；Some external lead-out wire adopts sleeve pipe to increase protection and insulating properties, adds material and winding process.
Coil rack, as the important spare part of catalyst product, is made up of heat-resisting, wear-resisting, are-tight and that impact strength is high thermoplastic, and the coil that coil rack is catalyst provides matrix.Do not have spacing between existing coil rack and pedestal and base, product in working order in can move up and down, cause that coil shakes, accelerating coil framework deformation and coil are aging；Product can move forward and backward when assembling, causes assembling difficulty, reduces production efficiency.
The contact support of existing catalyst, as the important feature part of supports contacts, is made up of heat-resisting, wear-resisting, are-tight and that impact strength is high solidity plastics.Touch spring provides contact pressure for contact, it is ensured that contact reliable contacts.The guiding that the assembling of existing touch spring is fitted without, installation effectiveness is relatively low.
The galvanic circle of catalyst is mainly made up of the conducting element such as static contact and contact bridge, requires that melting welding does not occur contact, and it is little as much as possible to wear and tear in the Guan Bi of contact and breaking course.Life-time service process has certain temperature rise, it is desirable to contact resistance is stable.Contact can produce electric arc in disjunction circuitry processes, and the adjoint high-energy of electric arc can cause contact melting welding.The electric arc produced in contact breaking course is extinguished in the effect of arc extinction part exactly.The installation site of contact and arc extinction part is accurate and firmly most important, has influence on the contact of contact and the size of contact resistance, and the normal operation of contact is extremely important.Existing contact location is to slot in base wall, can only carry out spacing to contact, and arc extinction part can only rely on the wall of pedestal as spacing, and spacing deficiency, and arc extinction part easily rocks.And contact heating is easily caused the deformation of base wall, so that arc extinction part is spacing unreliable.
In addition, base is as the major part of contact support member, and the mounting characteristic of catalyst is also all on base, and in transportation, base is also a very crackly part, so base needs certain intensity and rigidity, carry the vibration in catalyst work and transportation, impact etc..The bottom surface impact resistance of existing Foundation Plate of Contactor is not enough, and when being subject to greater impact, the sidewall at base easily occurs ftractureing with underside wall intersection.
