Abstract
The utility model relates to a large touching surface levity wall switch, which is used for solving the problems of bad hand feeling of a wall switch, the short service life of a wall switch, etc. The utility model is characterized in that the force arm of a button rocker and the touching surface of a switch can be enlarged, a novel metallic card type switching structure is adopted, and the stable electrical contact, the light hand feeling, and agile touch for switching of a power supply can be realized. The upper cover whose both ends are tilted of an arc pressing plate is integrated with the rocker, fixed screws of the switch is not exposed, and the utility model has the advantage of beautiful appearance. The utility model is suitable for installing on various decorated walls or wall plates.
Description
The utility model relates to appliance switch, exactly is a kind of levity wall switch of large touching surface.
At present, the switch of common employing is concealed, and specification has standard switch such as 75 types, 86 types.The mode of cut-offfing of this switch is that the stage clip fulcrum is done seesaw movements when moving, and the circuit tie point is switched on or switched off.The fulcrum of this kind switch is the key component that influences switch life and contact quality.Normally adopt insulating material such as plastics to manufacture.When using switch, fulcrum is stressed big because the button arm of force is little, easily causes abrasion deformation to make switch dumb or cause and electrically contact badly, causes the contact heating and makes the deliquescing of plastics fulcrum, and switch is very easy to damage like this.The big slightly switch of power just may generate heat when switching in addition, thereby easily causes the softening or aging switch that damages of plastics fulcrum because of the fulcrum of this class switch can not bear higher temperature.Because fulcrum is bad, contact point pressure is little, electrically contacts badly also may cause sparking and cause and catch fire.
When the objective of the invention is to realize Switching Power Supply, the light good hand touch of power reduces the fulcrum wearing and tearing and prolongs useful life of switch, contact contact stabilization and avoid loose contact to cause that switch heating or the switch that sparking caused damage or catch fire etc.
The present invention realizes like this.
Basic structure form of the present invention is on the insulator foot (3) of the contact of riveting over (1) and binding post (2), by another binding post (4) two ends U font with bayonet fulcrums (5) is fixed on the base (3).The copper sheet (7) of the square shape of contact-carrying (6) is inserted in the little seesaw (8) that insulating material makes to be gone up and is stuck in the bayonet socket of fulcrum (5).By spring (9) another Metallic card with bayonet (10) is linked to each other with square shape copper sheet (7), another bayonet socket of card (10) and fulcrum (5) is relative to be blocked and can do and arch upward and be folded down motion.With upper plastic cover pressing board (11) by being embedded on the little seesaw to increase the arm of force and to touch area.When opening switch, the upper end of pressing the loam cake pressing board, the loam cake pressing board drives little seesaw, and card (10) arches upward.Under the pulling force of spring, contact (1) and binding post (2) on the contact contact upper bed-plate (3) on the square shape copper sheet, power connection.When closing, click arbitrary position, loam cake pressing board lower end gently, loam cake pressing board (11) drives little seesaw (8) is folded down card (10) downwards, because spring (9) pulling force, the contact (6) on the square shape copper sheet (7) breaks away from base contact (1), electrically contacts disconnection.
The present invention has avoided the wearing and tearing of fulcrum owing to adopted fixed pivot and bayonet socket to arch upward to be folded down mode and move, and has prolonged the life-span of switch.And the loam cake pressing board of employing large tracts of land, the long arm of force, the light good hand touch of exerting oneself, pressure electrically contacts greatly between the contact, and not sparking is not generated heat.Our the loam cake pressing board of design is the circular arc streamline structure that has lifted up at two, has covered the fixing screw hole on the base, is contained in to look to be the screw hole grey easily dirty problem that falls that do not exist again elegant in appearance on the wall.Because the loam cake pressing board links to each other with the little seesaw of high insulating material, does not require the high-insulativity of loam cake pressing board.So last cover material can adopt general plastic injection-moulded form and its color can be chosen wantonly, makes switch attractive in appearance more beautiful.
Fig. 1. basic structure simplified schematic diagram of the present utility model.
Fig. 2 .U font fulcrum structure schematic diagram.
Provide the detail explanation of better scheme and the specification specified working condition of the concrete device that basis the utility model proposes below in conjunction with Fig. 2:
This utility model be one by on the hot-forming base of phenolic plastics (3), the contact (1) of the red metal of having riveted over and binding post (2).Be fixed on the base (3) with binding post (4) and the two ends brass U with bayonet font fulcrum (5) of screw (12), will intert with the square shape latten(-tin) (7) of alloy contact (6) and go up and be stuck in the bayonet socket of fulcrum at the little seesaw (8) that phenolic plastics hot pressing forms with another metal.By spring (9) another sheet metal with bayonet (10) is linked to each other with square shape copper sheet (7), another bayonet socket of card (10) and fulcrum (5) is relative to be blocked and can do and arch upward and be folded down motion.The injection molded upper plastic cover (11) that will almost cover whole switch is again gone up to increase the arm of force and to touch area by being embedded in little seesaw (8).Open loam cake (11) during installation, with corresponding screw be fixed on the wall by the screw hole on the base (3) or switch framework commonly used on.When opening switch, press the upper end of loam cake (11), loam cake drives little seesaw (8), and card (10) arches upward, and binding post (2), power connection are just connected in the contact (1) on contact (6) the contact upper bed-plate (3) of square shape copper sheet (7) under the pulling force of spring (9).When closing, click arbitrary position, lower end of loam cake (11) gently, loam cake (11) drives little seesaw (8) and card (10) is folded down downwards, because the pulling force of spring (9), the contact (6) of square shape copper sheet (7) breaks away from base contact (1), and power supply disconnects.
The utility model can also have other form or take other material, also two or more above-mentioned basic structure switches can be arranged in parallel within on the base and form the switch of may command two-way or multichannel.
