Abstract
The utility model relates to the field of electric apparatus and a part on an isolation switch, in particular to a fixed contact for a switch. The fixed contact for the switch comprises a contact mainbody which is provided with a bottom plate; and plates extending upwards, namely, a first extending plate and a second extending plate, are arranged at two sides of the bottom plate. The fixed contact is characterized in that a surrounding ring is arranged at the side part of the first extending plate, facing to the second extending plate; a spring is arranged inside the surrounding ring and outside the second extending plate; and the surrounding ring is arranged at the lower parts of the extending plates. The fixed contact for the switch has the advantages that the bad contact between a movable contact cutter and the fixed contact can not occur after the fixed contact pin is used for a long time.
Description
Technical field
The utility model relates to appliance field, relates to the parts on the isolating switch, specifically relates to a kind of switch fixed contact.
Background technology
Isolating switch has fixed contact, fixed contact is fixed on the base of isolating switch, the structure of fixed contact be the upper end have two stretch out close up pawl, two are closed up pawl and have the effect that sticks movable touch knife, in the prior art, fixed contact is that copper coin bends and forms, and the insertion of movable touch knife can influence two of moving contacts and closes up the open angle of pawl for a long time, comes in contact bad phenomenon, influences the normal use of isolating switch.
Summary of the invention
The purpose of this utility model is exactly at above-mentioned shortcoming, provides a kind of long-time use that the switch fixed contact of movable touch knife and fixed contact loose contact phenomenon can not take place.
The technical solution of the utility model is achieved in that the switch fixed contact, comprise contact body, contact body has base plate, the base plate both sides have the ejecting plate of extending upwardly, be respectively first to stretch out plate and second and stretch out plate, it is characterized in that: stretching out plate described first has one to encircle circle towards second sidepiece that stretches out plate, and circle is inner and second stretch out the plate outside and also have spring encircling; The described circle of encircling is in the bottom of stretching out plate.
The beneficial effects of the utility model are: such switch fixed contact has the advantage that movable touch knife and fixed contact loose contact phenomenon can not take place in long-time use.
Description of drawings
Fig. 1 is the structural representation of the utility model static contact isolation switch.
Wherein: 1, contact body 2, base plate 3, first stretch out plate 4, second stretch out plate 5, encircle the circle 6, spring
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, the switch fixed contact, comprise contact body 1, contact body 1 has base plate 2, base plate 2 both sides have the ejecting plate of extending upwardly, be respectively first to stretch out plate 3 and second and stretch out plate 4, it is characterized in that: stretching out plate 3 described first has one to encircle circle 5 towards second sidepiece that stretches out plate 4, and circle 5 is inner and second stretch out plate 4 outsides and also have spring 6 encircling; The described circle 5 of encircling is in the bottom of stretching out plate.
Because the effect of spring can make two of contact to stretch out harden and close good, reach the purpose of this utility model like this.
