Abstract
A zero arcing universal high power relay consists of a base, a yoke, an electromagnetic coil, a tension spring, an armature, a fixed contact assembly and a moving contact assembly. The fixed contact assembly is fixed in the base; magnetic conductive plates are stuck on the periphery of the fixed contact on or under a support board of the fixed contact. A contact system of the zero arcing universal high power relay has advantages of good anti-abrasive performance and long service life.
Description
One, affiliated technical field
The utility model relates to a kind of relay, refers in particular to a kind of zero general high power relay of arcing.
Two, background technology
In the prior art, general high power relay is made up of pedestal, yoke, solenoid, extension spring, armature, fixed contact assembly, moving contact component, the fixed contact assembly is fixed in the pedestal, but structurally there are some defectives, cause when relay disconnects, arcing occurring and ablation moving contact and fixed contact, the abrasion resistance properties of contact system is poor, influences the useful life of relay.
Three, utility model content
The purpose of this utility model is to provide a kind of zero general high power relay of arcing, and its contact system abrasion resistance properties is good, long service life.
For achieving the above object, the solution that the utility model is taked is: a kind of zero general high power relay of arcing, it is made up of pedestal, yoke, solenoid, extension spring, armature, fixed contact assembly, moving contact component, the fixed contact assembly is fixed in the pedestal, posts magnetic conduction sheet at the fixed contact periphery on the fixed contact support plate or down.
In the utility model, fixed contact is equivalent to be embedded in the magnetic conduction sheet mouth.When relay is worked, the electric arc arc root that produces on the dynamic and static contact can be successfully driven under the effect of arc current self-excitation magnetic field and magnetic conduction sheet, edge transitions between fixed contact is to magnetic conduction sheet, it is external by magnetic conduction sheet it to be pulled out relay, help extinguishing fast arcing like this, reach the purpose of zero arcing, improve the contact system abrasion resistance properties, be longer than existing relay useful life.
Four, description of drawings
Fig. 1 is the structural representation of present embodiment.
Fig. 2 is the end view of magnetic conduction sheet.
Fig. 3 is the front view of magnetic conduction sheet.
Among the figure: 1, pedestal, 2, yoke, 3, solenoid, 4, extension spring, 5, armature, 6, the fixed contact assembly, 7, moving contact component, 8, the fixed contact support plate, 9, magnetic conduction sheet.
Four, embodiment
Below in conjunction with embodiment and accompanying drawing thereof the utility model is remake description.
Referring to Fig. 1, a kind of zero general high power relay of arcing, it is made up of pedestal 1, yoke 2, solenoid 3, extension spring 3, armature 4, fixed contact assembly 5, moving contact component 6, and fixed contact assembly 5 is fixed in the pedestal 1, posts magnetic conduction sheet 9 at the fixed contact periphery on the fixed contact support plate 8 or down.
Referring to Fig. 2 and Fig. 3, magnetic conduction sheet 9 openings are U-shaped, and dual-side is rolled.
