Description
Technical field
The utility model relates to a kind of Protection switch of toppling over that is used for household electrical appliance, can realize especially that the current switching capacity is big, action force is easy to adjust, dependable performance and reliable electrical equipment that can the automation assembling topples over Protection switch.
Background technology
The household electrical appliance industry is to prevent that toppling over the potential safety hazard that causes because of electrical equipment is provided with a safety switch at the electrical equipment main circuit; Switch breaks off main circuit when electrical equipment tilts or falls; This safety switch is exactly the anti-electricity device dumping switch, and we are called for short dumping switch in being described below.Dumping switch has following 3 types from operating principle: 1. utilize weight to drive sensitive switch; When electrical equipment just immediately the gravity of weight through the conducting of switch depression bar driving switch closing of contact main circuit; When electrical equipment tilts or falls, act on weight gravity disappearance switch contact on the switch and break off main circuit and break off, this structure has the big but higher characteristics of cost of electric current of make-and-break; 2. utilize the gravity of conductive pieces to realize the circuit connection; Common this conductive pieces is made cylinder, the cylinder cross-over connection realizes circuit turn-on between two terminals; This structure has low but the characteristics that electric current of make-and-break is little of cost simple in structure, and therefore being used to small-power is in the little electric current electrical equipment; 3. utilize electrical equipment gravity to realize the circuit connection through shift knob; Shift knob is loaded on electrical equipment bottom surface and button protrusion electrical equipment baseplane downwards; When electrical equipment just immediately shift knob be pressed into---circuit turn-on; Shift knob is ejected by switch internal reset power when electrical equipment tilts or falls---and circuit breaks off; This structure has the big characteristics of electric current of make-and-break simple in structure simultaneously and is widely used in the household electrical appliance, and the utility model relates to this dumping switch that utilizes electrical equipment gravity to realize circuit connection principle.Two aspect major requirements are arranged: 1., require therefore that the electric current of make-and-break of switch own is big, reliability is high because dumping switch is used in the electric major loop, belong to power device with regard to dumping switch; Owing to utilize electrical equipment gravity to realize switch on and off different model electrical equipment weight differential big, as far as switch promptly be used in also must reach on the light electrical equipment break-make reliably, that button during simultaneously to switch on and off is pressed into the coherence request of stroke and pressure is higher.General dumping switch comprises pedestal, and is covered on shell on the pedestal, that form containing cavity, and can be loaded on the button of containing cavity with pushing; The two ends of said pedestal are provided with two relative terminals; One end and a terminal of said movable contact spring are fixed on the pedestal through rivet; The other end of said movable contact spring can flexiblely contact through the contact with another terminal, is connected through stage clip between said button and the movable contact spring contact-carrying end.When button is pressed, make the surrender of elasticity movable contact spring realize the circuit connection by power through stage clip, the elasticity movable contact spring recovers and makes the button return through stage clip when disappearing by power; The elasticity movable contact spring plays conduction and elastic reset function in the switch motion process; Bring a pair of contradiction for like this manufacturing movable contact spring: in order to guarantee big electric current of make-and-break; Just need to increase the movable contact spring sectional area and promptly use material thicker, elasticity just can not well satisfy the elasticity requirement and to the requirement of switch action force like this; And if in order to satisfy the requirement of switch to movable contact spring elasticity and action force; Just need do movable contact spring thinner; Electric current of make-and-break is just very little like this; Existing dumping switch is exactly that relatively thin so capacity electric current of make-and-break of movable contact spring has certain limitation; The long-pending elasticity movable contact spring of small bore flows through greatly electric current and generates heat to the movable contact spring elastic fatigue being reduced or follow the string and cause the contact adhesion or can not break off fully when work owing to switch simultaneously---switch failure, thus cause the safety function inefficacy of electrical equipment.
Summary of the invention
Address the above problem and will the movable contact spring conducting function of general switch realized separating from mechanism with spring function; Be that movable contact spring is made only the accomplishing conducting function of rigidity and another stage clip realization of spring function usefulness; The technical problem that the utility model will solve provides a kind of good springiness; Electric current of make-and-break is big, and can realize the automation assembling, and the reliable electrical equipment that efficiency of assembling is high is toppled over Protection switch.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: comprise pedestal, and be covered on shell on the pedestal, that form containing cavity, and can be loaded on the button of containing cavity with pushing; The two ends of said pedestal are provided with relative contact terminal and fulcrum terminal; Be provided with the movable contact spring relative with the fulcrum terminal in the said containing cavity with contact terminal; Said movable contact spring is arranged on the below of button; Be provided with first spring between said movable contact spring contact-carrying one end and the button, be provided with second spring between the said movable contact spring other end and the shell.
Further, the end that said movable contact spring is positioned at button is provided with first contact, and said contact terminal is provided with second contact that contacts with first contact.
Further, an end of said contact terminal and fulcrum terminal all inserts base extension to another side split riveted joint, and the other end stretches out shell and is used to connect lead.
Further, said movable contact spring is crimped on formation movable contact spring action fulcrum on the fulcrum terminal by first spring and second spring, and said movable contact spring action fulcrum is apart from the first spring axis distance, and distance second spring axis is apart from weak point.
Further, said movable contact spring is provided with two location notchs at the material cross direction of movable contact spring action position of the fulcrum, and the containing cavity correspondence position is provided with two positioning bars and cooperates with it; Said positioning bar top end is provided with the clamping part that is used to locate movable contact spring.
Further, said button is provided with endoporus, and said first spring is arranged in the endoporus.
The reliable electrical equipment of the utility model is toppled over Protection switch; Owing to be provided with the movable contact spring relative with the fulcrum terminal in the said containing cavity with contact terminal; Be provided with first spring between said movable contact spring one end and the button; Be provided with second spring between the said movable contact spring other end and the shell, said movable contact spring rotates first contact around fulcrum and contacts switch conduction with second contact under first spring action; Said movable contact spring rotates first contact and second contact separation around fulcrum under second spring action, switch breaks off; Therefore do not need movable contact spring itself to produce elasticity, movable contact spring can be done thicklyer, and electric current of make-and-break is big, while elasticity, and can realize the automation assembling, efficiency of assembling is high.
