Description
Technical field
The utility model relates to electromagnetic relay manufacturing technology field, is specifically related to a kind of electromagnetic relay with contact self-cleaning function.
Background technology
The contact of electromagnetic relay from produce to use during this period of time in, because long storage periods is in high temperature, high humidity with when containing in organic gas, sulfiding gas environment, contact surface will generate sulfide film and the oxide-film of one deck insulation, cause contact instability and contact fault; Simultaneously in relay use procedure, due to the electric arc meeting ablation contact surface produced when sound contact disconnects, affect the contact reliability of sound contact.Both of these case all can reduce contacting reliability, thus reduces the reliability of relay.
Utility model content
For solving the problems of the technologies described above, the utility model provides a kind of electromagnetic relay with contact self-cleaning function, this electromagnetic relay with contact self-cleaning function by arranging armature installation portion on reed, make moving contact grind off contact surface oxide layer or arc erosion vestige at fixed contact surface sliding, solve the problem that contacting reliability is low.
The utility model is achieved by the following technical programs.
A kind of electromagnetic relay with contact self-cleaning function that the utility model provides, comprises pedestal, case, iron yoke, coil, reed, armature, iron core, moving contact and fixed contact; Described pedestal is outside equipped with case, described pedestal is provided with coil, described iron core is arranged in the hole of coil, and one end of described iron core is connected with iron yoke, described iron yoke is connected in the top of coil and the connecting portion of reed, described reed is also provided with armature installation portion and the moving contact installation portion of circular sliding slopes, described armature installation portion is provided with armature, and described armature is relative with the end of iron core, described moving contact installation portion is provided with moving contact, and described fixed contact is arranged on pedestal.
Described pedestal is provided with lug plate, quiet contact chip A and quiet contact chip B, described lug plate, quiet contact chip A are connected with coil, fixed contact and iron yoke respectively with quiet contact chip B.
Described armature is riveted on armature installation portion.
The beneficial effects of the utility model are: between the armature installation portion and moving contact installation portion of the reed of electromagnetic relay, be arranged to circular sliding slopes, and when relay coil energising work, first sound contact contacts, and relay is in contact initial closed state; Now, fixed contact limits moving contact to be continued to move with armature component, and because armature and iron core now also exist gap, armature continues to move until fit with iron core to direction unshakable in one's determination under electromagnetic force; In this process, the circular arc on reed is by straightening in the process of armature to iron core movement, and in the process that the circular arc on reed straightens, moving contact is at fixed contact surface sliding; When relay coil power-off, moving contact reverse slide, because the mutual slip of sound contact has ground off contact surface oxide layer or arc erosion vestige in the process that relay switches on and off, improves relay reliability, and structure is simple, is easy to produce.

Embodiment
Further describe the technical solution of the utility model below, but described in claimed scope is not limited to.
A kind of electromagnetic relay with contact self-cleaning function as depicted in figs. 1 and 2, comprises pedestal 1, case 2, iron yoke 3, coil 4, reed 5, armature 6, iron core 7, moving contact 8 and fixed contact 9; Described pedestal 1 is outside equipped with case 2, described pedestal 1 is provided with coil 4, described iron core 7 is arranged in the hole of coil 4, and one end of described iron core 7 is connected with iron yoke 3, described iron yoke 3 is connected in the top of coil 4 with the connecting portion 51 of reed 5, described reed 5 is also provided with armature installation portion 52 and the moving contact installation portion 53 of circular arc 54 connection, described armature installation portion 52 is provided with armature 6, and described armature 6 is relative with the end of iron core 7, described moving contact installation portion 53 is provided with moving contact 8, and described fixed contact 9 is arranged on pedestal 1.
Described pedestal 1 is provided with lug plate 10, quiet contact chip A11 and quiet contact chip B12, described lug plate 10, quiet contact chip A11 are connected with coil 4, fixed contact 9 and iron yoke 3 respectively with quiet contact chip B12.
Described armature 6 is riveted on armature installation portion 52.
The utility model is in practical work process, and time initial, the state of relay as shown in Figure 3; When the lug plate 10 of electromagnetic relay is energized, coil 4 obtains electric, its both end voltage is raised generate an electromagnetic field, relay is converted to attracting state by off-state, the iron core be magnetized 7 pairs of armature 6 produce suction, and cause armature 6 to be with movable contact spring 5 to move to iron core 7, the moving contact 8 now on reed 5 is communicated with fixed contact 9, namely connect with quiet contact chip 11, load obtains electric work.Connect loop, dynamic and static contact when lug plate 10 obtains electric, now relay is converted to attracting state by off-state, contact circuit closed, because fixed contact 8 limits the motion of reed 5, reaches and realizes conversion and control effect.Meanwhile, because first moving contact 8 contacts with fixed contact 9, now fixed contact 9 limits moving contact 8 and continues to move with armature 6, and relay is in contact initial closed state, as shown in Figure 4; Now, fixed contact 9 limits the moving direction of moving contact 8, also limit the movement of reed 5 simultaneously.Owing to also there is gap between armature 6 and unshakable in one's determination 7, continue to move to 7 directions unshakable in one's determination until fit with unshakable in one's determination 7 under armature 6 electromagnetic force, as shown in Figure 5; In this process, because armature 6 and reed 5 are riveted together, the circular arc 54 of reed 5 in the process of armature 6 to 7 movements unshakable in one's determination by straightening, in the process that the circular arc 54 of reed 5 straightens, moving contact 8 is at fixed contact 9 surface sliding, slip has ground off contact surface oxide layer or arc erosion vestige, improves relay reliability.
When lug plate 10 power-off of electromagnetic relay, the electromagnetic field of coil 4 disappears, iron core 7 degaussing, disappear to the attraction that armature 6 produces, reed 5 restores under its counter-force effect, and moving contact 8 is moved to away from fixed contact 8 direction, moving contact 8 and fixed contact 9 is caused to disconnect, cause quiet contact chip A11 and quiet contact chip B12 to disconnect, load circuit and power-off, initial position got back to by reed 5.In power process, moving contact 8 slides along rightabout time closed on fixed contact 9 surface.The relative sliding utilizing relay to switch on and off sound contact in process grinds off contact surface oxide layer or arc erosion vestige, improves relay reliability, and structure is simple, is easy to produce.
