Abstract
The utility model discloses a self compensating safety isolating switch. The technical solution is that a still contact head and a moving plate are disposed between a panel and a connecting board, wherein the moving plate and a moving contact head are provided with a gemel, a hinge shaft and a pressing spring. The hinge shaft is disposed on one end of the moving contact head and the pressing spring is disposed on one side of the hinge shaft. A separating sleeve is disposed on the middle of the hinge shaft. A side link is fixed on a main rotating shaft. A connecting rod is arranged for connecting the side link with the moving plate. The contact between the moving plate and the still contact head is depended on the pressure of the spring. The function of self compensating the clearance of the moving contact head is performed, the contact pressure between the still contact head and the moving contact head are kept constant when the utility model is used for a long time or the operation frequency is high, the distance between the panel and the moving contact head is consistent, the thickness of the connecting rod is less than the thickness of the still contact head, the processing and assembling difficulty is decreased, the cost of the structure is low, the volume is small, the service life is long and the structure is safe and reliable.
Description
Technical field
The utility model relates to a kind of safety isolated switch, specifically is a kind of automatic compensation type safety isolated switch, belongs to the power supply technique field.
Background technology
Isolating switch is the large-scale switch of a kind of high voltage, is the essential important device of power supply circuits, and its reliability is directly determining the safety of power supply circuits and power supply unit.The present isolating switch that generally adopts, rely on the elasticity of fixed contact self when its moving contact and fixed contact are closed and guarantee contact area, but under the excessive situation of contact pressure, fixed contact causes quick wearing and tearing easily, because the elasticity of himself can not compensate, so contact area and contact pressure will decrease; If service time is long or frequency of operation tends to cause the contact loose contact when higher, thereby causes security incident, all there is above-mentioned defective in existing all types of switches, still do not have desirable isolating switch at present and solve this technical problem.
The utility model content
The purpose of this utility model is to solve isolating switch still can make the contact pressure maintenance of fixed contact and moving contact constant when long or frequency of operation is higher between in use, and a kind of safe and reliable, automatic compensation type safety isolated switch cheaply is provided.
The technical scheme that the utility model adopted is:
Fixed contact and moving plate are set between panel and connecting plate, between fixed contact, moving contact, panel and connecting plate, be provided with insulated column, at moving plate upper hinge moving contact, moving plate and moving contact upper hinge hinge also are provided with holddown spring, end at moving contact is provided with hinge, be provided with holddown spring in hinge one side, in the middle of hinge, be provided with spacer, between panel and connecting plate, be provided with main shaft, fixing side link on main shaft, connecting rod links together side link and moving plate, and the thickness of spacer is less than the thickness of fixed contact.
Contact between moving plate and the fixed contact relies on the pressure of spring, realized the function in automatic compensation moving contact gap, connect with insulated column between panel and the moving contact simultaneously, guaranteed the consistency of moving contact distance, be connected with connecting rod between moving plate and the main shaft, the thickness of connecting rod has reduced processing and assembly difficulty less than the thickness of fixed contact, this infrastructure cost is low, volume is little, long service life, and safe and reliable.

Accompanying drawing 2 is that the A-A of accompanying drawing 1 is to cutaway view.
Description of reference numerals is as follows:
Panel 1, connecting plate 2, moving plate 3, moving contact 4, main shaft 5, spacer 6, connecting rod 7, fixed contact 8, holddown spring 9, insulated column 10, handle 11, side link 12, hinge 13.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
2 moving plates (3) and 2 fixed contacts (8) are set between panel (1) and connecting plate (2), between moving plate (3), reach fixed contact (8) and panel (1), be provided with insulated column (10) between the connecting plate (2), moving plate (a 3) moving contact of upper hinge (4), moving contact (4) passes through hinge (13) hinge with moving plate (3), on hinge (13), be provided with holddown spring (9), be provided with hinge (13) in the end of moving contact (4), be provided with holddown spring (9) in hinge (13) one sides, in the middle of hinge (13), be provided with spacer (6), hinge main shaft (5) between panel (1) and connecting plate (2), go up fixedly side link (12) at main shaft (5), connecting rod (7) with side link (12) and moving contact (4) hinge together.
The utility model with insulated column will move plate, fixed contact is fixed between panel and the connecting plate, guarantee the consistency of distance between the contact by the consistency of insulated column height, at moving plate and moving contact upper hinge hinge and holddown spring is set, flexibility of rotating and the reliability that compresses have been guaranteed, be provided with holddown spring at moving contact and fixed contact contact position, realized the automatic compensation function of moving contact and fixed contact contact position, thereby moving contact is contacted with the good of fixed contact, guaranteed the safety of power supply circuits and power supply unit.
