FRAMEWORK OF RELAY AND RELAY

摘要

A framework part of a relay and a relay. An inner hollow portion and peripheral windows are formed by the framework. The windows are communicated with the exterior of the framework and the hollow portion. At least one group of contactors that can correspondingly contact are accommodated in the hollow portion. An arc gap is formed between the contactors that can correspondingly contact. The windows are aligned with the arc gap from an outer side. A main body of the framework is a hollowed injection molding framework, and has multiple windows that are aligned with the arc gap from the outer side, so that, under the precondition of ensuring the structural strength, materials can be reduced and the cost can be reduced. The windows can be used for installing functional components such as magnetic steel, a resistant act clip or an arcing and are extinguishing piece. The framework is made be applicable to relays and breakers having more functions and requirements, so as to improve a scope of application of products to a great extent and facilitate reduction of molds and other manufacturing costs.
