Abstract
The utility model discloses a touch switch. An outer frame is arranged out of a base in which a COM terminal soldering sheet, an NC terminal soldering sheet and an NO terminal soldering sheet are arranged. A tension spring and a driving sheet are arranged in the base. One end of the tension spring is sleeved at the middle support arm of the driving sheet, and the other end of the tension spring is hooked in the circular hole of the COM terminal soldering sheet. The lower end of the driving sheet is positioned between the NC terminal soldering sheet and the NO terminal soldering sheet. A push rod is positioned above the tension spring. The lower end of a screw connector is inserted into the outer frame, and the screw connector and the outer frame are mutually fixed. A nut is matched with the screw connector. The touch switch adopting the structure has the advantages of reduced working stroke, reinforced reliability, decreased volume of the switch and convenient installation.
Description
The utility model relates to the appliance switch field, relates in particular to a kind of push button touch switch.
The push button touch switch that uses in electric equipment at present is provided with two contact weld tabs and a contact spring in its pedestal, push rod directly acts on the contact spring, and push rod is provided with spring, and pedestal is outside equipped with housing; When reinforcing promoted push rod, two contact weld tabs were just connected by contact spring; When discharging push rod, under the effect of spring, push rod resets, and two contact weld tabs disconnect again.This kind touch switch has following shortcoming: one, impulse stroke is longer, because contact and disconnection all are not to carry out moment, so reliability is relatively poor, and the life-span is shorter; Two, volume is bigger, installs inconvenient.
The purpose of this utility model is to provide a kind of impulse stroke weak point, good reliability, volume touch switch little, easy for installation.
For achieving the above object, the technical solution adopted in the utility model is: described touch switch comprises: pedestal, pedestal is outside equipped with housing, be provided with COM terminal weld tabs in the pedestal, NC terminal weld tabs and NO terminal weld tabs, in pedestal, also be provided with extension spring and driving chip, one end of extension spring is enclosed within on the middle support arm of driving chip, the other end of extension spring colludes in the circular hole of COM terminal weld tabs, the driving chip lower end is positioned at the centre of NC terminal weld tabs and NO terminal weld tabs, the support arm of driving chip both sides contacts with the chase of COM terminal weld tabs both sides, push rod is positioned at the top of extension spring, the screw connector lower end is filled in housing and is interfixed, push rod passes the centre bore of screw connector, and nut matches with screw connector.
Further technical scheme of the present utility model is: on the basis of said structure, also be provided with mounting panel on screw connector, mounting panel is provided with a pad, nut with mounting panel and spacers on screw connector.
The utility model has the advantages that: adopted the touch switch of said structure, its impulse stroke is dwindled greatly; Again because of being the moment contact and disconnecting that reliability strengthens greatly; Reduced the volume of switch, saved raw material, installed also very convenient.Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model touch switch.
As shown in Figure 1, the structure of described touch switch installs to close: earlier NC terminal weld tabs (10) and NO terminal weld tabs (11) are inserted in the corresponding aperture of pedestal (12), one end of extension spring (4) is enclosed within on the middle support arm (7) of driving chip (8), the other end of extension spring (4) colludes in the circular hole (3) of COM terminal weld tabs (9), the lower end of driving chip (8) is positioned at the centre of NC terminal weld tabs (10) and NO terminal weld tabs (11), the support arm (6) of driving chip (8) both sides contacts with the chase (5) of COM terminal weld tabs (9) both sides, again COM terminal weld tabs (9) is inserted in the corresponding aperture of pedestal (12), these three weld tabs are split rivet clasp fix in the pedestal (12).Fill in screw connector (14) lower end in the housing (13) and split rivet clasp and form casing assembly surely, successively push rod (2) and casing assembly are packed into pedestal (12) and being fixed on the pedestal (12), mounting panel (15), pad (16) are contained on the screw connector (14), then nut (17) are screwed into screw connector (14) and tighten.
For making touch switch more attractive in appearance, use more conveniently, a push rod cap (1) can be set on the top of push rod (2).And can as required push rod cap (1) be designed to different shapes such as circle, square, ship shape.
The operation principle of this touch switch is: the support arm (6) of driving chip (8) both sides is a fulcrum with the chase (5) of COM terminal weld tabs (9) both sides, with extension spring (4) in the variation up and down of the tension point on the support arm (7) and about swing flexibly.Under the normality, because of extension spring (4) application point is in the upper end of support arm (7) in the middle of the driving chip (8), driving chip (8) swing to the right and is touched NC terminal weld tabs (10) and locate COM terminal weld tabs (9) and NC terminal weld tabs (10) conducting at this moment; When pressing push rod (2), push rod (2) lower end is pushed down extension spring (4) and is made extension spring (4) application point be displaced downwardly to the lower end of the middle support arm of driving chip (8) (7), under extension spring (4) tension, driving chip (8) promptly can be swung left moment, touch NO terminal weld tabs (11) and locate COM terminal weld tabs this moment (9) and NO terminal weld tabs (11) conducting.
Claims (3)
1, touch switch comprises: pedestal, and pedestal is outside equipped with housing, is provided with COM terminal weld tabs, NC terminal weld tabs and NO terminal weld tabs in the pedestal, also is provided with extension spring and driving chip in the pedestal; It is characterized in that: an end of extension spring is enclosed within on the middle support arm of driving chip, the other end of extension spring colludes in the circular hole of COM terminal weld tabs, the driving chip lower end is positioned at the centre of NC terminal weld tabs and NO terminal weld tabs, the support arm of driving chip both sides contacts with the chase of COM terminal weld tabs both sides, push rod is positioned at the top of extension spring, the screw connector lower end is filled in housing and is interfixed, and push rod passes the centre bore of screw connector, and nut matches with screw connector.
