Abstract

Provided is a horizontal type relay. The horizontal type relay mainly comprises a base plate, a coil, a support, a reinforcing part, a yoke, an armature, a spring sheet, a normally-closed input electrode and a normally-opened input electrode, wherein the coil is fixedly arranged on the base plate through the support and the reinforcing part, and the armature is fixedly arranged on the support through the spring sheet and is combined with the normally-closed input electrode in a closing mode. The horizontal type relay is simple in structure and convenient to install and use; due to the fact that the coil is horizontally arranged on the base plate, the size of the horizontal type relay is reduced greatly, and the space occupation is reduced; due to the multi-pin design, the purpose of multi-path control is achieved.

Description

A kind of horizontal relay

Technical field

The present invention relates to a kind of relay, exactly disclose a kind of horizontal 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.

Summary of the invention

A kind of horizontal relay, exactly for addressing the above problem, a kind of new technique is disclosed, mainly comprise: substrate (1), coil (2), support (3), girth member (4), yoke (5), armature (6), reed (7), the normally closed input utmost point (9) and often open input the utmost point (11), coil (2) is installed with on substrate (1) through support (3) and girth member (4), armature (6) is installed with on support through reed (7), and extremely closed with normally closed input, it is characterized in that: described substrate (1) is a square bakelite plate, described support (3) is " U " type metallic plate, longer another side is shorter to be on one side somebody's turn to do " U " type metallic plate, be bordering on " L " type, the end edge of a long side at this plate body arranges a longitudinal pin (13), the bottom margin of " U " type support (3) arranges two horizontal pins (15), a shorter lateral edges arranged outside output (14), the bottom of described coil (2) is installed with in " U " of support (3) type bottom, support (3) is plugged on substrate (1) through longitudinal pin (13) and two horizontal pins (15) of a side, coil (2) is horizontally-arranged on substrate (1), the yoke (5) of coil (2) other end passes girth member (4) and outstanding girth member (4), and is fixed on substrate (1) through girth member (4), described girth member (4) is a strip plastics plate body, on this plate body one end plate face, be provided with rectangular frame, this framework becomes vertical configuration with the face of substrate (1), this framework arranges opening towards a side of reed, in framework, be also provided with two input utmost points, be respectively the normally closed input utmost point (9) and often open input the utmost point (11), the normally closed input utmost point (9) front end arranges normally-closed contact (9 '), rear end arranges normally closed input utmost point pin (10), often open the input utmost point front end normally opened contact (11 ') is set, rear end arranges and often opens input utmost point pin (12), two input the utmost point respectively through normally closed input utmost point pin (10) and often open input utmost point pin (12) be plugged on substrate (1), framework and girth member (4) are one-body molded, described armature (6) be a strip soft magnetic metal plate body, one end holding is at the top of support (3), the parallel yoke of the other end (5) end face, described reed (7) is copper strip thin slice, between the residue section and the leading portion of beginning bending place of this copper sheets rear end after 5 bendings, form 100-120 degree angle, before and after two sections respectively riveting put on the rear end and support (3) of armature (6), guarantee that armature (6) remains to the state of upspringing away from the end face direction of yoke (5) under the effect of reed (7), contact (8) is put in the front end riveting of reed (7), contact (8) is through the opening of girth member (4) upper frame one side, stretch in the framework of girth member (4), and make contact between normally-closed contact (9 ') and normally opened contact (11 '), coil (2) no current passes through, contact (8) and normally-closed contact (9 ') under the effect of reed (7) in normally off, in the time that coil (2) has electric current to pass through, armature (6) is under the magnetic attraction of yoke (5), overcome the elastic force of reed (7), press close to yoke (5), and contact (8) with movable contact spring (7) separates with normally-closed contact (9 '), with normally opened contact (11 ') closure, coil (2) power-off, reed (7) resets.

The present invention is simple in structure, easy to install, and because coil is horizontally-arranged at substrate, and the earth reduced the volume of relay, and minimizing takes up room, and many pins designs have realized the object of multichannel control.

Accompanying drawing explanation

Referring to accompanying drawing, it is structural representation of the present invention.
