The switch is characterized in that the movable contact element comprises a contact rod, the contact rod is arranged in a contact rod sliding chute in the lower end of the button arm, the button arm is provided with a movable contact element spring of which the acting force is applied to the contact rod, the fixed contact element comprises a fixed contact pin, the upper end of the fixed contact pin is provided with a step-like fixed contact arm, when the button arm is pressed, the contact rod is disconnected from the fixed contact arm of the fixed contact pin, and when the button arm is reset, the contact rod is in contact with the fixed contact arm of the fixed contact pin.
Description
Technical field
The utility model relates to a kind of switch, especially push-button switch.
Background technology
Push-button switch be exactly in simple terms a kind of can automatically reset switch, push-button switch can be cylindrical, can be also square etc.Its structure mainly comprises housing and button, is fixed with contact pin on housing, on the pin of contact, is provided with fixed contact, in button lower end, is extended with spring base, and back-moving spring and movable contact piece are set on spring base.
Conventional button switch, generally adopts common upper positive pressure face circular shaft contact, and having used of a specified duration has carbon distribution between intermediate chain spindle and stationary contact part, causes loose contact.And two back-moving spring compression ratios differ, while causing center button axle out of plumb to reset, there is stuck phenomenon, to such an extent as to cannot reset.
Utility model content
The technical problems to be solved in the utility model is to provide the automatic decarbonizing of a kind of energy and is difficult for stuck novel push button switch.
For addressing the above problem, the technical solution adopted in the utility model comprises pedestal, button arm and upper shell, described button arm lower end arranges back-moving spring, side arm arranges movable contact piece, stationary contact part is set on described pedestal, it is characterized in that: described movable contact piece comprises contact rod, described contact rod is placed in the contact rod chute of button arm lower end, on button arm, be provided with active force and execute the movable contact piece spring to contact rod, described stationary contact part comprises static palping foot, described static palping foot upper end is provided with step-like stationary contact arm, under described button arm on time, the stationary contact arm of described contact rod and static palping foot disconnects, when described button arm resets, the stationary contact arm contact of described contact rod and static palping foot.
Described novel push button switch, is characterized in that: the described movable contact piece spring other end arranges steel ball, and the active force of described movable contact piece spring is fixed on the position, steel ball hole of button arm steel ball, the external part of described steel ball and pedestal snug engagement.
Described novel push button switch, it is characterized in that: described pedestal two inner sides are provided with stationary contact part slot, one side is provided with balanced support post, and described static palping foot inserts in stationary contact part slot fixing, described button arm one sidewall be provided with pedestal in the button arm chute that firmly matches of balanced support post.Novel key switch of the present utility model, has simple in structurely, touches rod and adopts the effective removing carbon of the friction-type way of contact with the stationary contact arm of static palping foot upper end step shape, and contact resets stable, the effect effectively increasing the service life.Meanwhile, the improvement of pedestal and button arm syndeton, can prevent stuck phenomenon.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1, the 2nd, exploded view of the present utility model;
Fig. 3 is the structural representation of button arm;
Fig. 4 is the structural representation of pedestal.
Embodiment
As shown in Figures 1 to 4, comprise pedestal 1, button arm 2 and upper shell 3, described button arm 2 lower ends arrange back-moving spring 4, side arm arranges movable contact piece, on described pedestal 1, stationary contact part are set.Described upper shell 3 is provided with left and right buckle 20, and in left and right, buckle madial wall is provided with fixing lug boss 21, and upper shell 3 upper ends have center square hole 22.Center square hole 22 adapts mutually with button arm 2 shapes.Left and right buckle 20 forms button mutually with the back-off 14 of pedestal 1 left and right sides, and fixing lug boss 21 and holddown groove 15 interfix and made to fix the integral body of key switch.
Movable contact piece described in the utility model comprises contact rod 5, described contact rod is placed in the contact rod chute 6 of button arm 2 lower ends, on button arm, be provided with active force and execute the movable contact piece spring 7 to contact rod, described stationary contact part comprises static palping foot 8, described static palping foot upper end is provided with step-like stationary contact arm 9, described button arm 2 times on time, described contact rod 5 disconnects with the stationary contact arm 9 of static palping foot 8, when described button arm 2 resets, described contact rod 5 contacts (contacting with stationary contact arm 9 upper end lug bosses) with the stationary contact arm 9 of static palping foot 8.
For further optimizing such scheme, described movable contact piece spring 7 other ends arrange steel ball 10, and the active force of described movable contact piece spring 7 is fixed on the position, steel ball hole 11 of button arm 2 steel ball 10, the external part of described steel ball 10 and pedestal 1 snug engagement.External part and pedestal 1 snug engagement with steel ball 7, be mainly used in reducing friction, and makes button arm 2 more smooth and easy by adding.
For further optimizing again such scheme, in 1 liang of inner side of pedestal, be provided with stationary contact part slot 13, bottom centre is provided with spring reference column 16, one side is provided with balanced support post 17, it is interior fixing that described static palping foot 8 inserts stationary contact part slot 13, on described spring reference column 16, back-moving spring 4 is installed, described back-moving spring 4 upper ends are placed in the spring eye 19 of button arm 2 lower ends, described button arm 2 one sidewalls be provided with pedestal 1 in the button arm chute 18 that firmly matches of balanced support post 17.The bottom centre of spring reference column in pedestal, the back-moving spring hole on button arm is also in button center, and upper shell Shang center square hole is in center, and these three centers are all on same central point.According to 3 definite straight line principles,, there is stuck phenomenon at the center of button arm in product and vertical thereby further eliminated when center button axle out of plumb resets.
Such scheme, applies downward power by button arm during console switch, and to realize the break-make conversion of the stationary contact arm of movable contact piece contact rod and stationary contact part, thereby while changing based on break-make, contact-making surface is the carbon deposit that friction-type produces while well having eliminated with power-off.Button arm end face contacts with pedestal inner bottom part face owing to pressing the button arm, and button stroke is never changed.After the power of button arm is discharged, the effect of the elastic force based on back-moving spring, thereby center and the vertical steadily smooth reset of button arm in product.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within being all included in protection range of the present utility model.
