Abstract
The utility model provides a limiting type double-breakpoint electromagnetic relay. A base plate of the electromagnetic relay is provided with a limit sheet, a convergence sheet and a lug respectively; an outer cover is arranged on the base plate; an iron core penetrates through a hole of a coil and is connected with an iron yoke provided with a trailing bracket; the iron yoke and an armature are respectively connected with a spring; a reed provided with movable contacts is connected with the armature; and the convergence sheet and the lug are respectively connected with a static contact and the coil. When in power-on, the two movable contacts on the reed are connected with the two static contacts simultaneously; when in power failure, the double breakpoints are utilized to lead two pair of contacts to cut off load simultaneously and increase the gaps of the contacts to at least two times of that of contacts of the common relay, thus greatly strengthening the cut-off load capacity of the relay; in addition, the limiting sheet limits the reed, thus leading the reed to return to the initial position after working every time, and realizing the application of the relay in high power equipment.
Description
Technical field
The utility model belongs to the mechanical ﹠ electrical technology field, particularly a kind of limit-type double break point electromagnetic relay.
Background technology
Normally used electromagnetic relay system adopts pair of contact, because of being subjected to the restriction of its structure, causes its contact gap can not be excessive, when relay disconnects, owing to the arcing phenomenon between its contact easily makes the contact stick together, so can not drive the operation of high power load.
Summary of the invention
The purpose of this utility model, being provides a kind of anti-vibration, arc resistant, shock-resistant at the problem of above-described relay existence, and contact gap is big, is suitable for the limit-type double break point electromagnetic relay of high power load operation.
The limit-type double break point electromagnetic relay of the utility model is made of seat board, outer cover and electromagnet system, contact system.Electromagnet system is made up of coil, iron yoke, bracket, iron core, armature assembly.Contact system is made up of spring, reed, moving contact, banking stop, fixed contact, the sheet that confluxes, lug plate.
The limit-type double break of the utility model is selected on the seat board of electromagnetic relay and is respectively arranged with the sheet that confluxes, lug plate and banking stop, and outer cover places on the seat board.The hole that iron core passes coil is connected with the iron yoke that is provided with bracket, and iron yoke, armature are connected with spring respectively, and the reed that is provided with moving contact is connected with armature, and the sheet that confluxes, lug plate are connected with fixed contact, coil respectively.
When the limit-type double break point electromagnetic relay of the utility model was switched on, two moving contacts on the reed were connected with two fixed contacts simultaneously; During outage, then utilize the double break point, make two pairs of contacts disconnecting consumers simultaneously, the gap that increases the contact is the twice of common relay contact gap at least, thereby greatly strengthened the ability that relay cuts off load, banking stop spacing to reed in addition can both be got back to initial position after making its each work, thereby be realized the application of relay in powerful device.

Embodiment
Below in conjunction with above-mentioned accompanying drawing example, the embodiment of the limit-type double break point electromagnetic relay of the utility model is described in further detail.
The example of the limit-type double break point electromagnetic relay of the utility model comprises seat board 1, outer cover 2 and electromagnet system, contact system.Electromagnet system constitutes the magnetic circuit of coil and magnet by coil 3, iron yoke 5, bracket 6, iron core 7, armature 8, and finishes closure or disconnect action by exciting current.Contact system is made up of spring 4, reed 9, moving contact 10, banking stop 11, fixed contact 12, the sheet 13 that confluxes, lug plate 14.
The limit-type double break of the utility model is selected on the seat board 1 of electromagnetic relay and is respectively arranged with the sheet 13 that confluxes, lug plate 14 and banking stop 11, and outer cover 2 places on the seat board 1.The hole that iron core 7 passes coil 3 is connected with the iron yoke 5 that is provided with bracket 6, and iron yoke 5, armature 8 are connected with spring 4 respectively.The reed 9 that is provided with moving contact 10 is connected with armature 8, and the sheet 13 that confluxes, lug plate 14 are connected with fixed contact 12, coil 3 respectively.
When the limit-type double break of the utility model is selected lug plate 14 energisings of electromagnetic relay, coil 3, its both end voltage is raise to generate an electromagnetic field, relay is converted to attracting state by off-state, 7 pairs of armature of the iron core that is magnetized 8 produce suction, cause armature 8 to drive reed 9 motions, and two moving contacts on the reed 9 10 are connected with two fixed contacts 12 simultaneously at this moment, reach final two sheets 13 that conflux and connect, load gets electric work.Its workflow is: 12 → one moving contact 10 → reeds 9 of 13 → one fixed contacts of sheet → another moving contact 10 → another fixed contact 12 → another sheet 13 that confluxes that confluxes.
Two sheets 13 that conflux connect promptly connects loop, dynamic and static contact, thereby reduce the voltage at coil 3 two ends gradually, this moment, relay was converted to off-state by attracting state, and loop, two pairs of contacts disconnects simultaneously, because banking stop 11 has limited the motion of reed 9, reach the purpose that realizes conversion and control.
When the limit-type double break of the utility model is selected lug plate 14 outages of electromagnetic relay, the magnetic field diminishes of coil 3, when iron core 7 degaussings produce 9 motions of suction disappearance back drive reed to armature 8, cause two moving contacts 10 and two fixed contacts 12 to disconnect, cause two sheets 13 that conflux to disconnect simultaneously, the load circuit outage, 11 pairs of reeds of banking stop 9 carry out spacing, make reed 9 can both get back to initial position after the motion at every turn.
