Description

A kind of new type of relay

Technical field

The utility model relates to a kind of relay.

Background technology

Relay is a kind of electronic control device, it has control system (claim not only input circuit) and by control system (but also claiming output loop), usually be applied in the automatic control circuit, in fact use less current to remove to control a kind of " automatic switch " of bigger electric current.In circuit, play effects such as automatic adjusting, safeguard protection, change-over circuit, use very extensive.The deficiency of the relay of Shi Yonging is the processing single-pieceization in the market, and cost is higher, and volume weight is big, and useful life is short, and driving power consumption is big, and switching speed is low.And external some micro-mechanical relays that use can't satisfy synchronizing close to the folding of multiloop contact is controlled, and the coil power consumption is higher, and homogeneity of product is poor.Simultaneously, some relay is also in parallel with controlled electric elements or connect in use, its attract current (being that relay produces the needed minimum current of closed action) or release current (being that relay produces the needed maximum current of release movement) are also constantly alternately changing relay down in working order, and in the practical application, closed path is far longer than release current, this unstable characteristic of relay, often the operate as normal to the controlled electric appliance in the circuit produces certain influence, simultaneously because attract current often will exceed 1.5 times of given electric current, just can guarantee the operate as normal of relay, solenoid is under the function of current that height changes, and very easily coil is consequently damaged in heating.
