Description
Technical field
The utility model is related to a kind of electromagnetic relay, and in particular to a kind of high stability electromagnetic relay.
Background technology
Electromagnetic relay is with control system (also known as input circuit) and by control system (also known as output loop), generally
Applied in automatic control circuit, it is actually that control larger current, higher electricity are removed with less electric current, relatively low voltage
One kind " automatic switch " of pressure.Therefore play in circuit automatically adjust, safeguard protection, the effect such as change-over circuit.With low tension
The development of device, the application of electromagnetic relay is more and more extensive, the also more and more higher of the requirement to electromagnetic relay.However, existing city
Miniature electro-magnetic relay contact performance is not sufficiently stable on field, one group of contact is often occurred and is not turned on phenomenon, so that directly shadow
The electrical endurance of product is rung.
The content of the invention
The purpose of this utility model is to overcome the defect of prior art, and there is provided a kind of simple in construction, temperature rise is low, load energy
The big high stability electromagnetic relay of power.
To achieve the above object, the utility model uses a kind of high stability electromagnetic relay, including pedestal and pedestal card
The shell, electromagnetic system, contact system of connection are detained, described electromagnetic system includes iron core, coil, yoke, armature, extension spring, institute
The contact system stated includes the dynamic spring that the insulation board, two spacing side by side that are arranged on armature are arranged on the upper surface of insulation board
The static contact being arranged at piece, each movable contact spring of correspondence on pedestal, the terminal pin being arranged on pedestal, described each movable contact spring direction
One end of static contact, which has, is respectively arranged with a movable contact on bifurcated, the two ends of bifurcated, and correspondence is each on described static contact
Place is provided with a dividing plate between corresponding two movable contact springs are respectively arranged with a stationary contact, described pedestal at movable contact,
And dividing plate separates the movable contact on two movable contact springs.
The beneficial effect of said structure is：The electromagnetic relay is provided with two movable contacts, movable contact spring on each movable contact spring
The temperature of contact when using can be reduced using double contact structure, makes the service life of electromagnetic relay longer, and two movable contacts
It is connected, it is to avoid the phenomenon that the contact of electromagnetic relay is not turned on, improves the reliability that movable contact is connected with stationary contact, and
The electromagnetic relay also has the advantages that simple in construction, temperature rise is low, load capacity is big, high stability.
Especially, reinforcement is provided with correspondence terminal pin on described pedestal, the reinforcement is fitted in the one of terminal pin
On side, and spot welding is connected with a weld tabs on the side of terminal pin.By being provided with the reinforcement for supporting wire pin on pedestal
Muscle, in spot welding, reinforcement can serve supporting role, increase the compression strength of a weld tabs, when spot welding pressure is excessive,
It is avoided that and point weld tabs is broken because pressure is excessive, it is ensured that is more attractive in appearance at spot welding, solid and reliable.
Brief description of the drawings
Fig. 1 is that the utility model embodiment removes the stereogram after shell.
Fig. 2 is the stereogram of the utility model movable contact spring.
Embodiment
As shown in Figure 1, 2, the utility model embodiment is a kind of high stability electromagnetic relay, including pedestal 10 and base
Shell, electromagnetic system 20, contact system 30 that seat 10 is snapped connection, described electromagnetic system 20 include iron core 21, coil 22, yoke
Iron 23, armature 24, extension spring 25, described contact system 30 include insulation board 31, two spacing side by side being arranged on armature 24
Be arranged at the movable contact spring 32 that is arranged on the upper surface of insulation board 31, each movable contact spring 32 of correspondence static contact 33 on pedestal 10,
The terminal pin 34 on pedestal 10 is arranged on, one end of described each movable contact spring 32 towards static contact 33 has bifurcated 321, bifurcated
It is respectively arranged with a movable contact 322 on 321 two ends, and is set respectively at each movable contact 322 of correspondence on described static contact 33
It is equipped with a stationary contact 331, described pedestal 10 place between two movable contact springs 32 of correspondence and is provided with a dividing plate 101, and every
Plate 101 separates the movable contact 322 on two movable contact springs 32.It is provided with and adds at correspondence terminal pin 34 on described pedestal 10
Strengthening tendons 102, the reinforcement 102 is fitted on the side of terminal pin 34, and spot welding is connected with a weld tabs on the side of terminal pin 34
35.By being provided with the reinforcement for supporting wire pin on pedestal, in spot welding, reinforcement can serve supporting role,
The compression strength of a weld tabs is increased, when spot welding pressure is excessive, is also avoided that and point weld tabs is broken because pressure is excessive, it is ensured that
It is more attractive in appearance at spot welding, solid and reliable.
The electromagnetic relay is provided with two movable contacts on each movable contact spring, and movable contact spring can be reduced using double contact structure to be made
Used time contact temperature, make the service life of electromagnetic relay longer, and two movable contacts are connected, it is to avoid electromagnetic relay
The phenomenon that is not turned on of contact, improve the reliability that movable contact is connected with stationary contact, and the electromagnetic relay also has structure
Simply, temperature rise is low, load capacity is big, high stability advantage.
