Description
Technical field
The utility model relates to switch, particularly relates to one and to fall Self-disconnecting switch.
Background technology
Switch is a kind of electric elements making current interruptions or conducting in circuit.The version of switch is varied.Different according to manner of execution during driving switch, be divided into push switch, rotary switch and rocker switch.Push switch and rocker switch all make switch be in the state of being turned on or off by pressing keys.Chinese Patent Application No. be 2011100719580, publication date be July 20 in 2011 day, be called in the patent documentation of " quick acting ship shape configuration switches " and disclose a kind of rocker switch.
Auto-breaking when falling to enable electrical equipment and improve electrical equipment use time fail safe, have devised Self-disconnecting switch of falling.Chinese Patent Application No. be 2006200732829, public authorized announcement date be May 2 in 2007 day, be called in the patent documentation of " the anti-tumbler switch of mechanical type " that disclosing one falls Self-disconnecting switch.Switch in this patent document comprises insulation crust and is fixed on two wiring pins of shell, cavity of resorption and epicoele is provided with in described shell, the inner of two wiring pins is positioned at cavity of resorption, the shell fragment that the inner being provided with same the wiring pin in one end in cavity of resorption is fixed together, heavy ball is provided with in epicoele, when switch is in erected state, heavy ball makes shell fragment also be connected to together with the inner of another kind of wiring pin by being pressed on shell fragment, and when switch is toppled over, heavy ball loses pressing effect to shell fragment, shell fragment is protruding and disconnect with the another in wiring pin.
Existing Self-disconnecting switch of falling has the following disadvantages: be generally to be fixed together with in two kinds of wiring pins one end of shell fragment, shell fragment (being also the connection of two wiring pins) is disconnected by the elastic force of shell fragment self, therefore shell fragment is power source and the conducting strip of connection two kinds of wiring pins, and shell fragment can produce the phenomenon that resistance increases ear heating after repeatedly opening and closing movement.
Utility model content
The resistance of conducting strip that the utility model provides a kind of connection a pair wiring pin can keep constant Self-disconnecting switch of falling for a long time, and solving the resistance that existing Self-disconnecting switch of falling connects the conducting strip of a pair wiring pin after repeatedly folding can increase and produce the problem of fever phenomenon.
Above technical problem is solved by following technical proposal: one is fallen Self-disconnecting switch, comprise insulation crust and two wiring pins being fixed on shell, cavity of resorption and epicoele is provided with in described shell, the inner of described two wiring pins is positioned at described cavity of resorption, heavy ball is provided with in described epicoele, it is characterized in that, be also provided with in described cavity of resorption under the effect of described heavy ball by the conducting strip be pressed on the inner of described two wiring pins and the spring to break making described conducting strip separate with described wiring pin.When the utility model is in erected state, the weight of heavy ball overcomes the elastic force of spring and makes conducting strip be connected to together with the inner of two wiring pins simultaneously, two wiring pin conducting by conducting strip.When generation is fallen, heavy ball loses the pressing effect to conducting strip, and spring releases energy and lifted by conducting strip, and conducting strip is thrown off with the inner of connecting pin, two kinds of wiring pins are disconnected.Because in make and break process, conducting strip does not produce twisting, therefore can not produce resistance and increase and the phenomenon of heating.
As preferably, the diapire of described epicoele is provided with pilot hole, and the upper surface of described conducting strip is connected with guide holder, and the upper end of described guide holder to be located in described pilot hole and to stretch into described epicoele, and described heavy ball is connected to described guide holder upper end.Can prevent conducting strip from producing with between wiring pin the action and produce sparking fever phenomenon of staggering.Good reliability during switch.
As preferably, described spring to break is stage clip, and described spring to break is supported on the below of described conducting strip.Layout is convenient, good reliability.
As preferably, the upper end of described guide holder is provided with large footpath section, and the diameter of described large footpath section is greater than the diameter of described pilot hole.The impulsive force that when can reduce reset, heavy ball produces conducting strip and the bending deformation quantity that conducting strip is subject to when impacting controlled.Spring to break can not produce flexural deformation and cause resistance or contact resistance to increase heating, prevents the better effects if of generating heat.
As preferably, be provided with the rectification be positioned at for a pair above described conducting strip in described cavity of resorption protruding, described guide holder is between described a pair rectification projection.Close up in process may produce conducting strip two ends upwarp distortion and cause contact area to diminish, contact resistance increase and heating aggravation phenomenon, when this design can make the generation of conducting strip two ends upwarp phenomenon, again correcting by correcting protruding suppressing action in the process disconnected, playing also can not produce contact resistance after repeatedly cut-offfing and increase and the effect of the phenomenon of heating.
As preferably, the described width corrected protruding width and be greater than described conducting strip.More reliable to the correcting of conducting strip.
As preferably, described spring to break and described guide holder are positioned on the same straight line extended along the vertical direction.In make and break process, conducting strip is not easy to produce bending metaboly more.
As preferably, described shell is also provided with installing hole, and described installing hole extends in described rectification projection.Use makes, and is arranged on miscellaneous equipment by the utility model by being through in installing hole by screw.Screw can also play the effect improving and correct protruding intensity.
The utility model has following advantage: when cut-offfing, conducting strip is not easy to produce metaboly, repeatedly cut-offs the resistance of rear conducting strip and contact resistance between conducting strip and wiring pin increases little, therefore repeatedly cut-offs and be also not easy to produce fever phenomenon.
