Abstract
The utility model relates to a high-power electromagnetic relay which is composed of a base, a yoke iron, an electromagnetic coil, a tension spring, an armature, an insulation carrier frame, a static contact assembly and a moving contact assembly, wherein, the static contact assembly is fixed in a static contact seat. The utility model is characterized in that a magnetic conductive sheet is respectively stuck to the upper part and the lower part of a supporting plate of a static contact; the upper part and the lower part of a supporting plate of the static contact are respectively welded with a static contact in an opening of each of the magnetic conductive sheets to form the static contact assembly. In the utility model, the static contacts is equivalent to the inlay of the static contacts in the magnetic conductive sheets. When the relay works, arc roots of electric arc which is generated by the static contacts can smoothly move to the magnetic conductive sheets from the edges of the static contacts to be pulled out of the relay in the self-excitation magnetic field of electric arc current and under the action of the magnetic conductive sheets; the electric arc is prolonged; the utility model is favorable for quick extinguishment; the electricity abrasion resistant performance of a contact system is improved; therefore, the actions of the magnetic conductive sheets around the static contacts are utilized furthest. The static contact assembly, the moving contact assembly and surrounding parts are effectively protected and the mechanical life of the relay is prolonged.
Description
Affiliated technical field
The utility model relates to a kind of electromagnetic relay, refers in particular to a kind of high-power magnetic relay.
Background technology
Electromagnetic relay is a kind of automatic electrical equipment, is widely used in the control of motor or route protection and Automation of Manufacturing Process.Its basic structure includes two parts: sense mechanism and actuator.Sense mechanism is the electromagnetic system of being made up of armature, iron core and coil often, and it can reflect the variation of relay input variable.Actuator is the contact system of being made up of dynamic and static contact and annex often, and it constitutes the output of relay.High-current relay in Control work, the electric arc especially severe of generation.When electric arc produces, often burn that contact or fusing are clung or phenomenon such as moving contact component distortion, even near the device the fixed contact assembly is damaged to some extent also, directly influenced the electric life and the mechanical endurance of relay.Chinese patent once disclosed a kind of " high-power magnetic relay " (CN87200024U, stop), form by pedestal, yoke, solenoid, extension spring, armature, insulator support, upper static contact contact sub-assembly, following fixed contact contact sub-assembly, movable contact spring spring combination spare, four groups of contacts and arc extinguishing barrier have been characterized in, but because it adopts the arc extinguishing barrier, thereby volume is bigger.
Summary of the invention
Task of the present utility model is to provide a kind of high-power magnetic relay, and its volume is little, and electric life and mechanical endurance are long.
For finishing above-mentioned task, the solution that the utility model is taked is: a kind of high-power magnetic relay, form by pedestal, yoke, solenoid, extension spring, armature, insulator support, fixed contact assembly, moving contact component, the fixed contact assembly is fixed in the stationary contact headstock, it is characterized in that on the fixed contact support plate or under post magnetic conduction sheet, in the mouth of magnetic conduction sheet, on the fixed contact support plate or weld down fixed contact, constitute described fixed contact assembly.
In the utility model, fixed contact is equivalent to be embedded in the magnetic conduction sheet, that is to say fixed contact around magnetic conduction sheet arranged.When relay is worked; the arc root of the electric arc that produces on the fixed contact can be successfully under the effect of arc current self-excitation magnetic field and magnetic conduction sheet by magnetic conduction sheet it to be pulled out relay from the edge transitions of fixed contact to magnetic conduction sheet external; elongated electric arc; help extinguishing fast; improved the anti-electric abrasioning performance of contact system; thereby maximally utilise the effect of the magnetic conduction sheet around the fixed contact; protect fixed contact assembly, moving contact component and peripheral devices effectively, improved the mechanical endurance of relay.
Description of drawings
Below in conjunction with embodiment and accompanying drawing thereof the utility model is remake description.
Fig. 1 is the structural representation of present embodiment.
Fig. 2 is a present embodiment fixed contact assembly schematic diagram.
Fig. 3 is a fixed contact assembly upward view.
Among the figure: 1, armature, 2, moving contact component, 3, the stationary contact headstock, 4, magnetic conduction sheet, 5, the fixed contact support plate, 6, fixed contact, 7, insulator support, 8, extension spring, 9, pedestal, 10, solenoid, 11, yoke, 12, window.
Embodiment
As shown in Figure 1, a kind of high-power magnetic relay, form by pedestal 9, yoke 11, solenoid 10, extension spring 8, armature 1, insulator support 7, fixed contact assembly, moving contact component 2, the fixed contact assembly is fixed in the stationary contact headstock 3, as shown in Figure 1-Figure 3, it is characterized in that on the fixed contact support plate 5 or under post magnetic conduction sheet 4, in the mouth of magnetic conduction sheet 4, on fixed contact support plate 5 or weld down fixed contact 6, constitute described fixed contact assembly.
As shown in Figure 1, have window 12 on the described stationary contact headstock 3, help arc transfer external to relay.
As shown in Figure 1, during the present embodiment action, the adhesive armature unshakable in one's determination 1 of solenoid 10, insulator support 7 moves down thereupon, and fixed contact assembly above moving contact component 2 breaks away from and following fixed contact assembly join; During solenoid 10 outages, armature 7 discharges, because the effect of extension spring 8, insulator support 7 restores to the original state, and moving contact component resets, and finishes release movement.
