Abstract
The utility model discloses a three-phase magnetic latching relay which is composed of a relay base body part, a wire connecting terminal and a shell body assembly. The relay base body part comprises a base assembly, a magnetic circuit assembly, a contact system assembly and a pushing sheet assembly. The wire connecting terminal comprises a wire inlet terminal, a wire outlet terminal and a ground terminal. The shell body assembly comprises an upper cover, a plastic shell body and a plurality of wire connecting coil assemblies. The relay base body part is arranged in the shell body assembly, and the upper cover is directly covered on the plastic shell body. As the relay systematically combines the functions of the three-phase magnetic latching relay and a wire connecting terminal box of an electric meter, when the relay is used by a user, the part of the terminal box is not needed; the structure of the relay is compact, and the cost is reduced; meanwhile, as the relay is installed at the outer part of the electric meter shell body, the functions of the electric meter cannot be affected by the heating of the relay, the action reliability of the relay cannot be affected by intense magnetic fields in the electric meter, and the using reliability of the electric meter can be effectively improved.
Description
Technical field
The utility model relates to a kind of relay assembly, especially a kind of three-phase magnetic latching relay.
Background technology
The supporting use of existing three-phase magnetic latching relay most power supply kilsyth basalt, all be to need other spot welding brush wire and installation sheet to realize generally with being connected of kilowatt-hour meter, and be built in the kilowatt-hour meter housing, more close with other components and parts in the kilowatt-hour meter, wiring when kilowatt-hour meter is furnished with terminal board in addition and installs for its client.This form is waste material not only, installing space is big, simultaneously also owing to use unnecessary material to make temperature rise higher, and because relay is installed on the enclosure interior of kilowatt-hour meter, be unfavorable for heat radiation, its temperature rise may have influence on the function of kilowatt-hour meter interior periphery components and parts, conversely, the high-intensity magnetic field of kilowatt-hour meter inside also may have influence on the reliable in action of relay and the contact reliability of contact.And relay will cause the disabler of whole kilowatt-hour meter in case lost efficacy, and when situation is serious even may burn kilowatt-hour meter, jeopardizes property and life security.
The utility model content
(1) technical problem that will solve
Technical problem to be solved in the utility model is to provide the three-phase magnetic latching relay at the existing in prior technology defective, solved prior art waste material, installing space big, because unnecessary conductor increases temperature rise, thereby and be built in and be unfavorable for dispelling the heat in the kilowatt-hour meter housing and defective that relay may lose efficacy and cause the kilowatt-hour meter allomeric function to lose efficacy because of the influence of kilowatt-hour meter high-intensity magnetic field.
(2) technical scheme
The technical scheme that its technical problem that solves the utility model adopts is: three-phase magnetic latching relay, its structure comprise magnetic latching relay body portion, binding post and shell combination part; Described body portion is made up of base combination, magnetic circuit combination, contact system combination and pushing piece; Described binding post is made up of three ends of incoming cables, three leading-out terminals and two earth terminals, wherein leading-out terminal and earth terminal and the plastic injection-moulded formation base combination that is integral; Described magnetic circuit combination, contact system combination and pushing piece combination are arranged in the cavity of base combination.
Described binding post stretches out from relay body portion both sides, wherein leading-out terminal and earth terminal and plastic injection-moulded being integral, and the end of incoming cables is the fixed contact link simultaneously, behind the good fixed contact of riveting, constitute the contact system combination with movable contact spring and moving contact etc., in the base combination of packing into.
Described shell combination is made up of plastic casing and a plurality of wiring circle, in order to replace its auxiliary products of original needs---and the terminal board part of kilowatt-hour meter configuration.
Described relay assembly is packed in the shell combination, and loam cake directly is buckled on the housing, not only relay matrix inside is covered sealing, and simultaneously relay part and shell combination partly being linked closely, it is as a whole to constitute.
(3) three-phase magnetic latching relay of the present utility model compared with prior art has following beneficial effect:
The utility model three-phase magnetic latching relay, the terminal board part of three-phase magnetic latching relay and kilowatt-hour meter is organically combined, realize making things convenient for and be connected with kilowatt-hour meter, when making kilowatt-hour meter, the client no longer needs other matching terminal box, also no longer need to use material and parts such as brush wire and installation sheet that relay is installed in addition, not only saved material, dwindled installing space, also, the relay contact current circuit make its temperature rise lower simultaneously because shortening, and because relay is installed in the outside of kilowatt-hour meter housing, can be because of the function of its warming-up effect kilowatt-hour meter, also can not have influence on the reliably working of relay because of the high-intensity magnetic field of kilowatt-hour meter inside, in the cost-effective while, can improve the functional reliability of kilowatt-hour meter integral body greatly.
