Abstract

The utility model relates to a rocker switch. A The technical problem to be solved by the utility model is to provide a rocker switch which has simple structure and more convenient wiring and can effectively prevent a pressure plate from falling off from a bolt. A The technical proposal for solving the problem is that the rocker switch is provided with a back base and a pressure cover which are linked mutually; the pressure cover is equipped with a switch transition piece which can swing around the pressure cover; the bottom of the transition piece pins a V-shaped seesaw by a swing spring; the bottom of the V-shaped seesaw is arranged at the support plate of a middle terminal component; the two ends of the V-shaped seesaw are respectively provided with a stationary contact component which is corresponding to movable contacts installed at the two ends of the V-shaped seesaw. The rocker switch is characterized in that the support plate is L shape, and the fixed end of the support plate forms an acute angle less than 60 degrees with a vertical plane. The rocker switch can be applied to various kinds of electric circuits.

Description

Rocker switch

Technical field

The utility model relates to a kind of rocker switch.Be mainly used in the various electric circuits.

Background technology

At present, most of switches on the market are seesaw type, its structure is, switch is by the spring compression seesaw, and seesaw is positioned on the binding post, and binding post comprises perpendicular to the support chip of seesaw and pressing plate, both connect by screw, a fixed contact assembly is respectively established at the seesaw two ends, and seesaw can rotate around the tie point of itself and binding post during toggle switch, controls seesaw and contacts with the fixed contact assembly of an end wherein.Yet the switch of this structure is not because the screw and the back seat of binding post form certain angle, and the easy and back seat generation frictional impact of screwdriver influences wiring when wiring; The phenomenon that pressing plate comes off from screw takes place in the switch of this structure easily in the wiring process in addition.

Summary of the invention

The technical problems to be solved in the utility model is: the problem at above-mentioned existence provides a kind of simple in structure, and wiring is convenient, and can effectively prevent the rocker switch that pressing plate comes off from screw.

The technical scheme that the utility model adopted is: rocker switch, have interconnective back seat and gland, installing on the described gland can be around the switch transition piece of its swing, " V " shape seesaw is pushed down by pendulum spring in this transition piece bottom, should place on the support chip of intermediate terminal assembly " V " shape seesaw bottom, described " V " shape seesaw both end sides respectively is provided with a fixed contact assembly, corresponding with the moving contact on being contained in " V " shape seesaw two ends, it is characterized in that: described support chip is L-shaped, and its stiff end becomes the acute angle less than 60 degree with perpendicular.

Described intermediate terminal assembly comprises support chip, screw and pressing plate, and the support end-grain cutting of described support chip has cutting edge and matches with " V " shape seesaw that two bottom sides has a breach, and the stiff end of support chip is fixed on the back seat, and is connected with pressing plate by screw.

The end side of described screw, back seat inwall both sides are shaped on the positioning bar that prevents that pressing plate from coming off.

The beneficial effects of the utility model are: adopt " L " shape support chip in the utility model, its stiff end and perpendicular form the acute angle less than 60 degree simultaneously, effectively avoided the phenomenon of screwdriver and back seat generation frictional impact in the wiring process, guaranteed wiring smoothly; In addition, the end side of screw, back seat inwall both sides are shaped on positioning bar, have thoroughly solved the problem that causes pressing plate to come off from screw because of careless or misoperation in the wiring process.

Embodiment

As shown in Figure 1 and Figure 2, present embodiment has interconnective back seat 1 and gland 2, installing on the described gland 2 can be around the switch transition piece 3 of its swing, " V " shape seesaw 5 is pushed down by pendulum spring 4 in this transition piece bottom, should place on the support chip 6-1 of intermediate terminal assembly 6 " V " shape seesaw bottom, the combining structure of this pendulum spring and seesaw has supper-fast make-break capacity, switch motion is smooth rapidly, operation lifetime is long, and has a superpower bearing capacity, can carry 64 fluorescent lamps, anti-instantaneous large-current impact capacity is strong.Described " V " shape seesaw 5 both end sides respectively are provided with a fixed contact assembly 7, are made up of the rectangular copper sheet 7-1 of bending, fixed contact 7-2, screw 6-3 and pressing plate 6-2, and fixed contact 7-2 is corresponding with the moving contact 8 on being contained in " V " shape seesaw 5 two ends.Described support chip 6-1 is L-shaped, and its stiff end becomes the acute angle less than 60 degree with perpendicular, to avoid screwdriver and back seat generation frictional impact in the wiring process, make more convenient to operate.

Described intermediate terminal assembly 6 comprises support chip 6-1, screw 6-3 and pressing plate 6-2, the support end-grain cutting at described support chip 6-1 top has cutting edge (angle) and has the bottom contact matching of " V " shape seesaw 5 of breach with two bottom sides, can make the seesaw swing more flexible, reliable and stable, not arcing is not ablated.The stiff end of support chip 6-1 is fixed on the back seat 1, and is connected with pressing plate 6-2 by screw 6-3.End side, back seat 1 inwall both sides at described screw 6-3 are shaped on the positioning bar 9 that prevents that pressing plate 6-2 from coming off.
