Abstract
An electromagnetic control relay static contact mechanism comprises a base; a lower static contact board is fixed on the left table board of the base, and an upper static contact board is fixed on the right table board thereof; the lower static contact board is plane-type, and the upper static contact board is step-type; arc striking pieces are fixed on the upper static contact board and the lower static contact board; an upper stationary contact is fixed on the upper static contact board and positioned between the arc striking pieces; a lower stationary contact is fixed on the lower static contact board and positioned between the arc striking pieces; and the lower stationary contact and the upper stationary contact are oppositely positioned with certain distance. The mechanism has reasonable design, and improves the sensitivity, the reliability and prolongs the service life of the relay.
Description
Technical field
The utility model relates to a kind of control relay, refers in particular to a kind of electromagnetic type control relay static contact mechanism.
Background technology
Electromagnetic type control relay (abbreviation relay) is widely used in the electric power system, plays control, amplifies, interlocks, protects and regulates, to realize the automation of control procedure.The basic structure of relay includes two parts.(1) sense mechanism: be the electromagnetic system of being made up of armature, iron core and coil often, it can reflect the variation of relay input variable.(2) actuator: often be the contact system that dynamic and static contact and annex are formed, it constitutes the output of relay.Static contact mechanism is an important component part in the actuator, and it directly influences the sensitivity and the reliability of relay.At present, magnetic-type control relay static contact mechanism is undesirable, directly influences the adhesive of moving contact, thereby has influenced sensitivity, reliability and and the useful life of relay.
The utility model content
The purpose of this utility model is to provide a kind of electromagnetic type control relay dynamic contact mechanism, and it is reasonable in design, has improved sensitivity, reliability and the useful life of relay.
For achieving the above object, the solution that the utility model is taked is, a kind of electromagnetic type control relay static contact mechanism, it comprises base, quiet contact plate is fixed on the left table top of base down, going up quiet contact plate is fixed on the right table top of base, quiet contact plate is a plane formula down, going up quiet contact plate is step, at last quiet contact plate and following fixing striking sheet on the quiet contact plate, last fixed contact is fixed on and is on the quiet contact plate in the middle of the striking sheet, and following fixed contact is fixed on down and is on the quiet contact plate in the middle of the striking sheet, following fixed contact and a be separated by segment distance relative with last fixed contact.
This static contact mechanism is reasonable in design since on last quiet contact plate and time quiet contact plate fixing striking sheet, improved the arc extinction performance of relay, thereby improved the useful life of relay; Because quiet contact plate is designed to plane formula down, to go up quiet contact plate and be designed to step, they are fixed on the table top of base, make down fixed contact accurately relative with last fixed contact, and standoff distance is accurate, have improved sensitivity, the reliability of relay.

Fig. 2 is electromagnetic type control relay (removing a case) end view.
Fig. 3 is following quiet contact plate (band arc quenching plate and following fixed contact) stereogram.
Fig. 4 goes up quiet contact plate (band arc quenching plate) stereogram.
Among the figure: 1, base, 2, following quiet contact plate, 3, go up quiet contact plate, 4, the striking sheet, 5, go up fixed contact, 6, fixed contact down.
Embodiment
Below in conjunction with embodiment and accompanying drawing thereof the utility model is remake description.
Referring to Fig. 1 and Fig. 4, a kind of electromagnetic type control relay static contact mechanism, it comprises base 1, quiet contact plate 2 is fixed on the left table top of base 1 down, going up quiet contact plate 3 is fixed on the right table top of base 1, quiet contact plate 2 is a plane formula down, going up quiet contact plate 3 is step, at last quiet contact plate 3 and fixing striking sheet 4 on the quiet contact plate 2 down, last fixed contact 5 is fixed on and is on the quiet contact plate 3 in the middle of the striking sheet 4, following fixed contact 6 is fixed on down and is in the middle of the striking sheet 4 following fixed contact 6 and last the fixed contact 5 relative and segment distances of being separated by on the quiet contact plate 2.
Claims (1)
1. electromagnetic type control relay static contact mechanism, it comprises base (1), it is characterized in that: following quiet contact plate (2) is fixed on the left table top of base (1), going up quiet contact plate (3) is fixed on the right table top of base (1), quiet contact plate (2) is a plane formula down, going up quiet contact plate (3) is step, go up fixedly striking sheet (4) at last quiet contact plate (3) and following quiet contact plate (2), last fixed contact (5) is fixed on and is on the quiet contact plate (3) in the middle of the striking sheet (4), following fixed contact (6) is fixed on down and is in the middle of the striking sheet (4) following fixed contact (6) and a be separated by segment distance relative with last fixed contact (5) on the quiet contact plate (2).
