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, the pedestal being placed on base and the coil being installed between base and pedestal composition.
Coil directly affects electric property index and functional reliability as the important component part of the electromagnetic system of catalyst, its quality.Existing to enamel-covered wire protectiveness, insulating properties deficiency, the paint film easily causing inside and outside lead-out wire enamel-covered wire is easily scraped, and causes coil short circuit or open circuit occur；Some external lead-out wire uses 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 coil to shake, accelerating coil framework deformation and coil are aging；Product can move forward and backward when assembling, causes assembling difficulty, reduces production efficiency.
