Abstract
The invention relates to a surge protector, wherein an insulating sliding plate is arranged between a lightning protection device and a pin soldering terminal and is placed at an end close to a pin on one side of a movable contact sheet, the area of the insulating sliding plate is greater than that of the movable contact sheet, one end of the insulating sliding plate is close to a flange of a base while the other end is arranged close to the welding surface of a product, a return spring is arranged between the insulating sliding plate and the flange of the base, and one end of the return spring resists against the insulating sliding plate while the other end resists against the flange of the base. When the surge protector fails, a low melting point alloy connecting the movable contact sheet and a piezoresistor is melted by heat so that the movable contact sheet is disconnected with the piezoresistor, the front end of the insulating sliding plate close to the welding surface of the product is not obstructed any more, and the back end slides to the welding surface of the product under the action of the restoring force of the return spring so that the movable contact sheet is thoroughly isolated from the piezoresistor in the shortest time to put an end to short circuit and fire hazard caused by electric arc follow current, thus the safety of the product is better, and product deterioration indications and alarm signals are presented at the same time.
Description
Technical field
The present invention relates to a kind of surge protector.
Background technology
Surge protector adopts traditional piezo-resistance as core component on the existing market, and a utmost point of this piezo-resistance welds with the spring tripping mechanism weld tabs that the wiring pin links to each other mutually with low-melting alloy.When surge protector lost efficacy, piezo-resistance produced a large amount of heat energy in moment, made low-melting alloy melt back tripping mechanism device and produced action, made its operational environment that logs off.But the tripping mechanism of existing surge protector can not be guaranteed when pressure responsive resistor failure because of the limitation of its structure, makes it produce action in effective time, in time the environment of deactivating of safety.And when action, the two still was on the same tangent plane, caused producing the high-voltage arc afterflow between the weld tabs of surge protector and the piezo-resistance, made the danger that electrical equipment, equipment produce short circuit and fire.
Summary of the invention
The objective of the invention is in order to overcome the shortcoming that prior art exists, and provide a kind of structure simpler, can realize the disengaging with work system in the shortest time when product failure, and effectively prevent electric arc, safer, the more reliable surge protector of use.
For achieving the above object; the present invention adopts a kind of surge protector; comprise base; 2 pins; lightning protection component; the pin weld tabs; the insulation slide plate; 2 pins; lightning protection component; the pin weld tabs all is arranged on the base; one of them pin one end links to each other with the pin weld tabs; another pin one end links to each other with lightning protection component; 2 pins are by pin weld tabs and the lightning protection component loop that is electrically connected to form; lightning protection component is fixed on the upper surface of base; the other end relative and the pin link extends to form movable contact spring on the pin weld tabs; movable contact spring is welded on the product solder side of lightning protection component and constitutes and is electrically connected by low-melting alloy; between lightning protection component and pin weld tabs, be provided with the insulation slide plate; the insulation slide plate places movable contact spring one side near pin one end; the area of insulation slide plate is greater than the area of movable contact spring; insulation slide plate one end is near the rib of base; other end close neighbour product solder side is provided with; be provided with back-moving spring between the rib of insulation slide plate and base; back-moving spring one end is pressed on the insulation slide plate, and the other end is pressed on the rib of base.
The movable contact spring that the present invention further is set on the pin weld tabs forms resilient fold near product solder side one side.In the purpose that resilient fold is set on the movable contact spring is that easier resilience of movable contact spring and bounce amount are higher when low-melting alloy is met the heat thawing.
The present invention further is set to insulate, and rib one side near base forms stopper slot on the arc extinguishing board, 2 special-shaped conductive metal sheets are arranged in the stopper slot along the glide direction of insulation slide plate, 2 special-shaped conductive metal sheet symmetry close neighbours are provided with, and constitute by the contact of going up separately and to electrically contact, expose base portion on 2 special-shaped conductive metal sheets and form lead end.Can connect other indicating equipments at the lead end of 2 special-shaped conductive metal sheets,, can be used for indicating the internal work situation of surge protector such as LED light or the like.Before the insulation slide plate did not move, 2 conductive metal sheets were to electrically contact, the outside indicating equipment operate as normal that links to each other; After the action of insulation slide plate, 2 conductive metal sheets are separated from each other, and the outside indicating equipment that links to each other can quit work, and the user can know that surge protector had lost efficacy.
The present invention further is set to insulate and forms bar near product solder side one side on the slide plate, is forming the observation window corresponding with bar on the rib opposite side relatively on the base.Bar and observation window are set, and are the internal work situations of grasping surge protector for convenience, and when the slippage of insulation slide plate, bar is more and more nearer from observation window, and the user can know that surge protector had lost efficacy.
Rib one side that the present invention further is set to close base on the insulation slide plate extends to form the conflict sheet, and a sensitive switch is set above the conflict sheet, and the operating knob of sensitive switch is pressed on the upper surface of conflict sheet.Can on sensitive switch, connect other indicating equipments,, can be used for indicating the internal work situation of surge protector such as LED light or the like.Before the insulation slide plate did not move, the operating knob of sensitive switch was failure to actuate, the outside indicating equipment operate as normal that links to each other; After the action of insulation slide plate, the operating knob of sensitive switch then moves, and the outside indicating equipment that links to each other can quit work, and the user can know that surge protector had lost efficacy.
The present invention further be set to again to insulate both sides of slide plate form spacing shoulder block, and 2 back-moving springs place spacing shoulder block place respectively.
When surge protector lost efficacy; be used to connect the low-melting alloy chance heat thawing of movable contact spring and piezo-resistance; movable contact spring is separated with piezo-resistance; insulation nose near close neighbour's product solder side has not had to stop; the rear end is subjected to the restoring force effect of back-moving spring; to the slippage of product solder side; make it thoroughly that movable contact spring and piezo-resistance is isolated in the shortest time; short circuit, disaster hidden-trouble have been stopped because of the electric arc afterflow causes; make security of products better, and provide indication of product deterioration and alarm signal simultaneously.And the movable contact spring on the pin weld tabs makes easier resilience of movable contact spring and bounce amount higher near product solder side one side formation resilient fold.
