Abstract
The invention discloses a magnetic latching relay with a flexible static contact part. The magnetic latching relay comprises a casing, a magnetic circuit part, a movable contact part and the static contact part, wherein the magnetic circuit part, the movable contact part and the static contact part are correspondingly installed in the casing. The static contact part comprises a static spring base, a static contact and a static contact piece. The static contact is installed on the static contact piece, the static spring base is provided with a mounting through hole and a fixing part, one end of the static contact piece is fixed on the static spring base through the fixing part, the other end of the static contact piece adheres to the mounting through hole in a suspended mode, and an n-shaped gap is reserved between the outer edge of the static contact piece and the inner side edge of the mounting through hole. The magnetic latching relay has the advantages that due to the fact that the static contact piece adheres in the suspended mode, the static contact piece can effectively alleviate impact force, times of shaking during the momentary contact of two contacts is greatly reduced, reliable contact time of the contacts is shortened, momentary arc discharge of the contacts caused by the shaking is reduced, and the use performance of the relay is greatly improved.
Description
Technical field
The present invention relates to a kind of relay, more particularly, is a kind of magnetic latching relay with flexible quiet contact portion.
Background technology
Magnetic latching relay is a kind of new type of relay growing up in recent years, it is the effect that a kind of closure or off-state rely on permanent magnet completely, after mutual conversion between closure and off-state only relies on the excitation coil of DC pulse voltage forward or backwards of certain width, moment completes, conventionally contact is when disconnection or closure state, relay coil is without continuing energising, only relies on the magnetic force of permanent magnet just can maintain the contacts status of relay constant.
Along with national intelligent grid development, make the products such as picture Intelligent capacitor, intelligent compound switch simultaneously also more and more higher to the requirement of its built-in magnetic latching relay further widely in intelligent grid application.The dynamic and static contact of existing magnetic latching relay is in opening and closing large current load process, because the incidental impulsive force of Contact moving contact is larger, after it contacts with fixed contact because the contact chatter frequency is many, when Circuits System can not complete reliably switching action during at operating passing zero and can cause between contact arcing number of times frequent, contact is bonding, heating is serious, greatly reduce the serviceability of relay, so such relay can not meet the requirement of the occasions such as Intelligent capacitor, combination switch.
Summary of the invention
Because prior art exists the problems referred to above, the present invention proposes a kind of magnetic latching relay with flexible quiet contact portion, and it can effectively solve the problems referred to above of prior art.
The present invention addresses the above problem by the following technical programs:
A kind of magnetic latching relay with flexible quiet contact portion, comprise housing, and correspondence is installed on the magnetic circuit part in described housing, moving contact portion and quiet contact portion, described quiet contact portion comprises quiet spring abutment, fixed contact and static contact, described fixed contact is installed on described static contact, described quiet spring abutment is provided with installs through hole and fixed part, described quiet spring abutment is fixed on by described fixed part in described static contact one end, its other end is unsettled to be fitted on described installation through hole, and between the inner side edge of the outward flange of described static contact and described installation through hole, leave one " n " type gap.
Described fixed part is the boss which is provided with a plurality of fixed legs, and described static contact is provided with the fixing hole mating with described fixed leg diameter, and described static contact is sheathed on described fixed leg by this fixing hole.
Described fixed part is many group rivet holes, and described static contact is provided with the fixing hole mating with described rivet hole, by rivet, passes described rivet hole and fixing hole is fixed described quiet spring abutment and static contact.
Described magnetic circuit part comprises the bobbin that is being wound around enamel covered wire, connects respectively the coil leading foot of enamel covered wire beginning, end, and the yoke of magnetic conduction.
Described moving contact portion bonds by epoxy resin and described housing.
By above technical scheme, the magnetic latching relay with flexible quiet contact portion of the present invention, it has the following advantages: be applied in and control in large current load process, when its two contact moment, the impulsive force that moving contact acts on fixed contact is very large, because static contact is half unsettled laminating, static contact can effectively relax this impulsive force, shake number of times while having reduced significantly by two contact moment contacts, shortened the time of the reliable contact of contact, reduced contact due to the moment arcing that shake causes, relay serviceability is significantly promoted; In this relay, in stationary contact system, each parts production and processing is simple, reliable, greatly reduces the production cost of product.
