Abstract

The invention relates to a relay, and belongs to the technical field of relays. The relay comprises an upper press cover, a contact bin, main contacts, a movable contact assembly and porcelain covers, wherein the upper press cover is arranged on the contact bin, the movable contact assembly and the contact bin are fixed, the main contacts are in contact with the movable contact assembly, the porcelain covers are arranged in the contact bin, the movable contact assembly comprises a movable contact, an insulation support seat, a stainless steel connection rod and a movable iron core, one end of the stainless steel connection rod sequentially penetrates through the insulation support seat and the movable contact, the other end of the stainless steel connection rod is connected with the movable iron core in a penetrating way, the insulation support seat is matched with the contact bin, and the main contacts are in contact with the movable contact. The relay is reasonable in structure, low in production, simple in process, cheap in equipment cost and short in production period, and is safe and reliable.

Description

technical field [0001] The invention relates to a relay, in particular to a safe, reliable and low-cost relay, which belongs to the technical field of relays. Background technique [0002] The existing DC contactor has a ceramic package, that is, the entire contact chamber is made of ceramic raw materials; although the ceramic packaged contactor has superior performance, the manufacturing cost is high, the process is complicated, and the equipment investment is high; and the production cycle is long. [0003] Epoxy-encapsulated contactors refer to sealing the contact compartment with epoxy, and the contact compartment is made of plastic. Adding a ceramic cover to the plastic contact chamber can effectively reduce the production cost, the process is simple, the equipment is cheap and the production cycle is short, and the product performance is basically consistent with the ceramic package product, so it is particularly necessary to design a contactor with this structure. ...
