Description

Relay

Technical field:

The present invention relates to a kind of electronic control device, specifically is a kind of relay.

Background technology:

We know, when the relay in the routine techniques is worked, as long as add certain voltage at the coil two ends; Will flow through certain electric current in the coil, thereby produce galvanomagnetic effect, armature can be in the moving contact and the fixed contact on the static contact spring piece (normally opened contact) adhesive that drive under the effect of electromagnetic attracting force on the movable contact spring; External circuit has just been connected in moving contact and fixed contact adhesive later on, is in conducting state in order to make external circuit always, and we need continue to keep moving contact and fixed contact adhesive to coil power supply; But; Not only can cause waste of electric energy for for a long time coil power supply, but also can cause the caloric value of coil to continue to increase, influence the useful life of coil.

Summary of the invention:

The technical problem that the present invention will solve is, provides a kind of and can save electric energy, the relay in extension coil useful life.

Technical solution of the present invention is; A kind of relay with following structure is provided: comprise pedestal, bonnet, movable contact spring I, movable contact spring II, skeleton, be connected the coil on the skeleton and be connected to the quiet contact chip I on the pedestal, moving spring lead-out tablet I, quiet contact chip II and moving spring lead-out tablet II from left to right in turn; Pedestal is connected with bonnet, is connected with fixed contact I on the quiet contact chip I, and movable contact spring I bottom is connected with moving spring lead-out tablet I; Movable contact spring I top is connected with the moving contact I that can be pull-in on the fixed contact I; Be connected with fixed contact II on the quiet contact chip II, movable contact spring II bottom is connected with moving spring lead-out tablet II, and movable contact spring II top is connected with the moving contact II that can be pull-in on the fixed contact II; Wherein, Coil is the coil of a convertible polarity, and skeleton is positioned at movable contact spring I left side, be connected with between skeleton and movable contact spring I and the movable contact spring II one can be when coil blackout continued maintenance movable contact spring I and movable contact spring II be in coil electricity the maintaining body of state.

Relay of the present invention, wherein, maintaining body can comprise push rod, magnet steel body, left yoke, right yoke, connecting plate and be connected upper armature and the lower armature on the magnet steel body; Left side yoke and right yoke are connected to the left part and the right part of skeleton, and connecting plate is connected between left yoke and the right yoke, and the magnet steel body is rotatably connected between connecting plate and the pedestal; Magnet steel body top is connected with push rod; The left and right two ends of push rod slidably are connected with quiet contact chip I and quiet contact chip II respectively, and the push rod middle part is provided with two protruding pin I, and the push rod right part is provided with two protruding pin II; Movable contact spring I top is between two protruding pin I, and movable contact spring II top is between two protruding pin II.

Relay of the present invention, wherein, movable contact spring I top and protruding pin I contact site are provided with flexure strip I, and movable contact spring II top and protruding pin II contact site are provided with flexure strip II.

After adopting above structure; Compared with prior art; Relay of the present invention has the following advantages: need hold-in winding energising always just can make the moving contact on the movable contact spring different with the fixed contact adhesive on the static contact spring piece with prior art; Since relay of the present invention be connected with between skeleton and movable contact spring I and the movable contact spring II one can be when the coil blackout continued keeps movable contact spring I and movable contact spring II to be in coil electricity the maintaining body of state, therefore, relay of the present invention when connection external circuit or disconnecting external circuit only to coil feeding immediate current; Can break off the electric current of coil then, state when maintaining body can make movable contact spring I and movable contact spring II be in coil electricity.Coil in the relay of the present invention is after moving contact I and fixed contact I and moving contact II and fixed contact II are switched on or switched off; There is not electric current to pass through in the coil; Therefore, relay of the present invention has not only effectively been practiced thrift electric energy, but also has shortened the conduction time of coil; And then greatly reduce the caloric value of coil, the useful life of further having improved coil.

Maintaining body comprises push rod, magnet steel body, left yoke, right yoke, connecting plate and is connected upper armature and the lower armature on the magnet steel body, when relay of the present invention is worked, when promptly connecting external circuit; The user can make left yoke produce magnetic through the polarity that changes coil, and relies on this magnetic to attract upper armature left part counter-clockwise swing, in the process of upper armature left part counter-clockwise swing; Magnetic rigid body top can drive push rod and be moved to the left; At this moment, protruding pin I on the push rod and protruding pin II can drive movable contact spring I respectively and movable contact spring II is moved to the left, and finally makes moving contact I and fixed contact I and moving contact II and fixed contact II adhesive; After treating that the upper armature left part is inhaled left yoke; Upper armature can keep the state of adhesive always with left yoke under the effect of magnetic rigid body permanent magnetism, at this moment, the user can be with the dump of coil.When relay of the present invention needed the disconnecting external circuit, the user can make right yoke produce magnetic through the polarity that changes coil in the other direction, at this moment; Yoke to the right can swung and inhale to upper armature clockwise under the effect of right yoke magnetic, inhale in the process of yoke to the right at upper armature, and magnet steel body top then can drive push rod and move right; In the process that push rod moves right; Protruding pin I and protruding pin II then can order about moving contact I and fixed contact I and moving contact II and fixed contact II and break off, and treat that the upper armature right part inhales to the right after the yoke, and upper armature can keep the state of adhesive always with right yoke under the effect of magnetic rigid body permanent magnetism; At this moment, the user can be with the dump of coil.

The setting of flexure strip I can effectively increase the adhesive pressure between moving contact I and the fixed contact I; Thereby guarantee the fastness after moving contact I and the fixed contact I adhesive; And the setting of flexure strip II can effectively increase the adhesive pressure between moving contact II and the fixed contact II, thereby guarantees the fastness after moving contact II and the fixed contact II adhesive.
