Abstract

The invention provides an arc extinguishing mechanism, a relay frame and a relay. The relay frame comprises a frame body, at least one piece of magnetic steel and at least one arc resistant piece. The frame body is provided with a hollow portion. The hollow portion internally contains contact points capable of being in corresponding contact. The magnetic steel is installed on the frame body and located on the periphery of an arc gap. The magnetic steel can conduct arc extinguishing on an arc generated at the position of the arc gap. The arc resistant pieces are installed on the frame body and located in the arc extinguishing action direction of the magnetic steel. The arc can be cooled through arc resistant materials, the product reliability can be improved, the electrical life can be prolonged, the cost of the relay frame is lower than that of a frame made of full-ceramic materials, and the structure of the frame is simpler.

Description

technical field [0001] The invention relates to a relay, in particular to an arc-resistant arc extinguishing mechanism, a relay frame and a relay. Background technique [0002] In some AC or DC contactors (relays), it generally includes a frame body, a lead-out part, a moving spring part, a magnetic circuit system, and a pushing mechanism. The lead-out part includes a lead-out and a static contact; the static contact is fixedly connected to the bottom of the lead-out. The moving contact is fixedly installed on the moving reed of the moving spring part, which is correspondingly located in the frame main body, and the moving spring part is pushed by the pushing mechanism. The static contacts of the lead-out part are respectively matched with the movable contacts of the moving spring part to complete the on or off of the relay. Here, the frame main body material main body is plastic. [0003] However, when the relay is applied to a relatively high load, when the breaking vol...
