Abstract
The utility model discloses a kind of DC relay arc extinguishing structure, including a magnet, the magnet is positioned at the side of the plane where the central shaft of two face terminals of relay, the relay has a housing, the bottom of the housing is provided with mounting groove, and the magnet is located at the bottom of the housing and is positioned in the mounting groove.The utility model DC relay arc extinguishing structure has simple in construction, easy for installation, the good advantage of arc quenching effect.
Description
Technical field
The utility model is related to a kind of DC relay, more particularly to a kind of DC relay arc extinguishing structure.
Background technology
Relay be it is a kind of gone to control with less electric current, relatively low voltage larger electric current, higher voltage it is automatic
Switch.It realizes that this switching function is by the electromagnet for being arranged inside, by being passed through small electric to magnet spool
Stream so that electromagnet produce magnetic field, using the generation or disappearance in magnetic field adhesive or unclamp armature, and then drive electroconductive elastic sheet it
Between adhesive or disconnection, realize conducting to big current loop.However, during high-voltage great-current is controlled, when control relay
When device disconnects the circuit of high current, two face terminals can disconnection generation electric arc in a flash, these electric arcs both make high current
Also there is conducting in circuit, and can produce influence to the element inside relay again, relay even be burnt out when serious, therefore need
Nip in the bud electric arc.In the prior art, the arc extinguishing structure of most of relays makes to produce at face terminals and gone out using magnet
Arc power, so as to extinguish electric arc by arc extinguishing power, however, the magnet is built in the inside of relay, makes relay internal structure
More complicated, arc quenching effect is poor, and magnet installs or taken out difficult, safeguards inconvenience.
Utility model content
The purpose of this utility model is to provide a kind of simple in construction, easy for installation, good DC relay of arc quenching effect
Arc extinguishing structure.
To achieve these goals, the DC relay arc extinguishing structure that the utility model is provided includes a magnet, the magnetic
Iron has a housing, the shell positioned at the side of the plane where the central shaft of two face terminals of relay, the relay
The bottom of body is provided with mounting groove, and the magnet is located at the bottom of the housing and is positioned in the mounting groove.
Compared with prior art, because the utility model is by opening up mounting groove in the bottom of the housing, and by institute
State magnet to be positioned in the mounting groove of the housing, so as to so that the magnet can be installed easily from the bottom surface of the housing
And take out, it is simple in construction, install very convenient, and because the magnet is positioned at the plane where the central shaft of two face terminals
Side, therefore, between face terminals described in two produce electric arc when, can be by both direction in arc length direction and direction phase
Anti- arc extinguishing power, so that electric arc extinguishes rapidly, arc quenching effect is good.
It is preferred that the side of the magnet dorsad face terminals offers recessed, the madial wall of the mounting groove of positioning
Provided with recessed corresponding convex is positioned with described, it is recessed interior that the convex is sticked in the positioning.It is described positioning it is recessed with it is described fixed
The convex cooperation in position can be such that the magnet is rapidly positioned with the mounting groove.
It is preferred that the length of the magnet is not less than the distance between central shaft of face terminals described in two.Using one
The big magnet of structure is conducive to increasing flux, arc extinguishing power is improved, so as to strengthen arc quenching effect.

Fig. 2 is the structure chart of the arc extinguishing structure of the utility model DC relay.
Fig. 3 is the sectional view of the arc extinguishing structure of the utility model DC relay.
Embodiment
To describe technology contents of the present utility model, construction feature, the effect realized in detail, below in conjunction with embodiment
And coordinate accompanying drawing to be explained in detail.
As shown in Figure 1, Figure 2 and Figure 3, the utility model DC relay arc extinguishing structure 100 includes a magnet 1, the magnetic
Iron 1 is positioned at the side of the plane where the central shaft of two face terminals 2 of relay, and the relay has a housing 3, described
The bottom of housing 3 is provided with mounting groove 31, and the magnet 1 is located at the bottom of the housing 3 and is positioned in the mounting groove 31.Institute
The side for stating the dorsad face terminals 2 of magnet 1 offers positioning recessed 11, the madial wall of the mounting groove 31 be provided with it is described fixed
The recessed 11 corresponding convex 31a in position, the convex 31a are sticked in the positioning recessed 11.The length of the magnet 1 is not less than
The distance between central shaft of face terminals 2 described in two.Be conducive to increasing flux using the big magnet of integrative-structure, improve arc extinguishing
Power, so as to strengthen arc quenching effect.
Compared with prior art, because the utility model is by opening up mounting groove 31 in the bottom of the housing 3, and will
The magnet 1 is arranged in the mounting groove 31 of the housing 3, then by setting convex 31a in the mounting groove 31, in institute
State the side of magnet 1 and open up positioning recessed 11, being coordinated using the positioning recessed 11 and convex 31a can make the magnet 1 fast
Fast ground is positioned with the mounting groove 31, so as to so that the magnet 1 easily can be installed and taken from the bottom surface of the housing 3
Go out, it is simple in construction, install very convenient, and because the magnet 1 is positioned at the plane where the central shaft of two face terminals 2
Side, therefore, can be by both direction in arc length direction and direction phase when producing electric arc between face terminals 2 described in two
Anti- arc extinguishing power, so that electric arc extinguishes rapidly, arc quenching effect is good.
Above disclosed is only preferred embodiments of the present utility model, can not limit the utility model with this certainly
Interest field, therefore equivalent variations made according to present utility model application the scope of the claims still fall within the utility model and are covered
Scope.
