Background technology
Relay is a kind of electronic control device, plays the works such as automatic adjustment, safeguard protection, conversion circuit in circuit
With.Its operation principle is to add certain voltage at coil both ends, certain electric current is will pass through in coil, in magnetic circuit
Upper generation galvanomagnetic-effect, armature will overcome under the action of electromagnetic attracting force to be returned power and is drawn to iron core, is moved on spring to drive
Movable contact is attracted with the stationary contact on quiet spring, reaches conducting effect in circuit.
Existing technical disadvantages are：Since movable contact spring is limited by product mechanical property, and in order to improve contact
Be connected sensitivity, head width is generally less smaller than the width of the rear part, cause on its position sectional area by electric current
Density is larger, and product fever is more serious, and then causes relay internal temperature rise larger, and product is influenced whether when product works
Electric life；The prior art obviously cannot meet requirement.
Invention content
It is an object of the invention to overcome above-mentioned deficiency existing in the prior art, and provide a kind of low fever high life electricity
Magnetic relay armature structure.
Technical solution is used by the present invention solves the above problems：Including be arranged relay body interior coil and
Shaped iron core combined structure, coil outer are provided with fixed frame, and the main body of fixed frame is set as slab construction, is provided in the middle part of fixed frame
The avoiding hollow groove of stationary contact is avoided, the rectangular structure in side of the fixed frame is connected with yoke, yoke and fixed frame edge
The side of connection is connected with armature, the lateral surface connection of the yoke and armature above fixed frame surface, and in the side
There is a movable contact spring of rectangular state, the rivet of protrusion, two right angles of movable contact spring are all formed on the lateral surface of yoke and armature
Face is respectively by corresponding rivet interlacement yoke and armature, and yoke is servo-actuated the rectangular state of reed with armature and is arranged, the dynamic spring
The front end of piece extends to the outside of armature edge, and is provided with the rivet hole of connection movable contact, and movable contact is fixedly connected on rivet hole, moves
Contact is corresponding with stationary contact, and the front end lamination of the movable contact spring is provided with splitter, the both ends of splitter respectively with movable contact spring
The contact of the front end surfaces Liang Chu is fixedly connected, and surface is in the electric current direction of motion of relay turning circuit at two, in splitter
Portion is not contacted with movable contact spring, and the independent independent turning circuit on the outside of movable contact spring is formed on splitter.
This structure is mainly used on the mobile armature part of electromagnetic relay, and splitter is with movable contact spring, armature with contact
It links together and ensure that the intensity of connection structure, while it is elasticity that splitter, which uses the good metal of electric conductivity, splitter,
Preferable structure detaches among it with movable contact spring structure in non-contacting state, and splitter moves spring for conduction, by the part
The original magnitude of current shunting of on piece, increases the current carrying area in the portion, reduces current density, improves the conducting wire effect of movable contact spring
Rate, since the throughput of electric current becomes larger, the resistance heat amount of being reduced by electric current on unit area, movable contact spring reduces, and reduces
Cooling requirements have clear advantage for the equipment running in hot environment.
Further, splitter be specially the front end being connect with movable contact, with the rear end of armature rivet interlacement and connect
The elastic connection of front and rear end is encircleed, and the splitter surface of front and rear end is contacted with the corresponding surface of movable contact spring respectively, elasticity
Connection arch is not contacted with movable contact spring.The front and rear end of the structure of splitter has good plane connectivity, the effect of conducting
It is good, while being encircleed by elastic connection and being detached with movable contact spring, the current path of separation is formed, good shunting effect is played, simultaneously
Due to the design of elastic connection arch, the problem of original head area of splitter small easy bending, is addressed, and splitter improves
The intensity of structure, and elastic connection arch has good elasticity, is suitble to the frequent movement of movable contact.
Further, the splitter is the surface that more than two laminations are connected to movable contact spring simultaneously, each layer of shunting
It is mutually not in contact with each other between the elastic connection arch of piece, and is different from per the height that a piece of elastic connection is encircleed.In order to further
Raising shunting effect multiple splitters can be set, further increase the effect of shunting.
Further, elastic connection arch is semicircular configuration, the both ends of elastic connection arch connect straight front end with
Rear end.The elasticity of semicircular configuration is good, does not have stress defect, is suitble to use on the conductive material frequently moved, raising finishes
The intensity of structure, and facilitate processing.
Further, the semicircular configuration of the splitter of the outer layer is both less than the semi-circular knot of the splitter of its internal layer
Structure, and be in concentric structure.The elastic connection of splitter is encircleed when multi-disc cooperates, in order to ensure that semicircular configuration is phase
It mutually detaches, using concentric semicircular structure, is also convenient for distinguishing in assembly.
Further, the splitter uses Copper alloy material, the surface of splitter to be coated with conducting metal plated layer.Shunting
Piece needs are contacted with the surface of movable contact spring could improve turn-on effect, so needing to coat the good gold of electric conductivity on its surface
Belong to coating.
Further, pass through rivet interlacement or mutually weldering between the splitter and between splitter and movable contact spring
It connects.Rivet can utilize the rivet on existing structure, and easy to process, if desired better intensity, may be used welding.
Further, the angle section of the movable contact spring forms the arc-shaped elasticity dog-ear more than right angle, elastic dog-ear
External arc surface exceed the straight flange structure of itself, elastic dog-ear is not contacted with armature.The angle section of movable contact spring is band
Moving armature and movable contact movement primary structure, require Elasticity performance will preferably, arc-shaped elasticity dog-ear can carry
The elasticity of high structure, and stress is reduced, improve the intensity of structure.
Further, the elastic dog-ear of the movable contact spring is set as the strip structure of two or more separation, strip structure
It is mutually parallel and isometric.Since elastic dog-ear is the structure frequently moved, metal fatigue is will produce, if being not provided with separation
Strip structure total can be made to be broken completely when generating breach, so that the bulk life time of relay is declined, the item of separation
Shape structure is that will not influence each other generating metal fatigue.
Compared with prior art, the present invention haing the following advantages and effect：This structure is mainly used in electromagnetic relay
On mobile armature part, splitter ensure that the intensity of connection structure, same time-division with movable contact spring, armature together with contact portion
It is the preferable structure of elasticity that flow, which uses the good metal of electric conductivity, splitter, detaches be in movable contact spring structure among it
Original magnitude of current on the part movable contact spring is shunted for conduction, increases the current-carrying in the portion by non-contacting state, splitter
Area reduces current density, improves the conductor efficiency of movable contact spring, since the throughput of electric current becomes larger, on unit area
Reduced by electric current, the resistance heat amount of movable contact spring reduces, and reduces cooling requirements, and tool is operated for the equipment in hot environment
There is clear advantage.
