Abstract

The utility model discloses a novel relay. The relay comprises a pedestal, a coil, a yoke, an armature, a reed, a contact, a lead, a wiring board, an output terminal, a support, a compressed spring rivet, a compressed spring, a normally-closed input pole, a normally-closed input pole contact, a normally-open input pole, a normally-open input pole contact, a normally-open input pole terminal, a coil terminal, a fixing rivet and a tension spring. The coil is fixed into a shell on the pedestal through the yoke. The coil terminal is connected to the coil so as to form a control circuit. The reed, the output terminal, the normally-closed input pole and the normally-open input pole form a working circuit together. The working circuit and the control circuit form a main body of the relay. The coil is sealed so that the coil is ensured not to be polluted by electrostatic dust. A damage of an instant arc generated when the circuit is closed to the coil is avoided and the service life of the coil is prolonged.

Description

A kind of new type of relay

Technical field

The utility model relates to a kind of new type 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), conventionally be applied in automatic control circuit, in fact use less electric current to go to control the one " automatic switch " of larger electric current.In circuit, play the effects such as automatic adjusting, safeguard protection, change-over circuit, apply very extensive.The deficiency of the relay using is in the market processing single-piece, and cost is higher, and volume weight is large, and useful life is short, and driving power consumption is large, and switching speed is low.And external some micro-mechanical relays that use can't meet synchronizing close to the folding of multiloop contact is controlled, and 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, relay in working order lower 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) is also constantly alternately changing, and in practical application, closed path is far longer than release current, this unstable characteristic of relay, often the normal work of the controlled electric appliance in circuit is produced to certain impact, simultaneously because attract current often will exceed 1.5 times of given electric current, just can guarantee the normal work of relay, under the function of current that solenoid changes at height, very easily coil is consequently damaged in heating.
