Description

Skate Switch

The invention relates to the invention of skate Switch, say so in more detail about giving the operator invention with the skate Switch of location sense.

The skate Switch of setting up detent mechanism always, opening clear 58-85730 communique remembers my structure in fact as Japan, is well-known.The disclosed skate Switch of this communique is by passing through the manually operated operating body of operator, remain the activity contact pin of folder shape by this operating body, if setting separated by a certain interval is provided with in plastic pedestal in fixed tabs, and with operating body on the formations such as reed that connect of the wedge bullet that forms, the mode of seizing fixed tabs with activity contact pin on both sides by the arms fits together.

During use, the operator moves back and forth the orientation of operating body to fixed tabs, and activity contact pin contacts selectively with fixed tabs or throws off, and carries out the switching of open and close.At this moment, the wedge of operating body contacts with the jut of reed or throws off, and therefore produces the location sense, and this location sense is transmitted to operator's finger.So the operator can confirm whether the open and close action is finished according to the location sense.

But above-mentioned skate Switch always must have reed in order to produce the location sense, and existing component number increases, and is unfavorable for reducing cost, realizes problems such as miniaturization.

In addition, fixed tabs generally is to strike out required form with the copper coin of surface plating noble metal etc. as base material, so there is not coating on the plane of disruption of punching press, base material exposes outside.Yet, in above-mentioned skate Switch always, fixed tabs is to erect simply to be arranged on the pedestal, not only exposes the sliding surface with activity contact pin, and exposed the plane of disruption (end face), so the plane of disruption of fixed tabs is easy to be corroded.

The present invention considers the actual conditions of technology always, purpose is for a kind of reed that saves is provided, help reducing cost, realizing the skate Switch of miniaturization, another object of the present invention provides a kind of fixed tabs corrosion of preventing, the skate Switch that reliability is high.

The excrescence of the present invention's integrally formed breakwater shape of being seized on both sides by the arms by activity contact pin in plastic pedestal, the one side of this excrescence is exposed fixed tabs, and another side forms wedge.Like this, on the excrescence of the breakwater shape of being seized on both sides by the arms, need only and form wedge by activity contact pin, when with the folder shape activity contact pin of operating body interlock when excrescence moves, activity contact pin just contacts selectively, breaks away from the fixed tabs that excrescence simultaneously exposes, carry out the change action of open and close, wedge contact, the disengaging that the excrescence another side is formed produces the location sense simultaneously.

Skate Switch of the present invention has the plurality of fixed contact pin that setting separated by a certain interval is provided with in plastic pedestal, can contact with these fixed tabs, the folder shape activity contact pin that breaks away from, and the operating body that this activity contact pin is moved back and forth to above-mentioned fixed tabs direction, the excrescence of integrally formed breakwater shape of being seized on both sides by the arms by activity contact pin in said base, the one side of this excrescence is exposed said fixing contact pin, and the another side of this excrescence forms wedge.

But above-mentioned excrescence is according to needs Cheng Yilie or some row of circuit, when excrescence forms some row, in order to produce stable location sense, preferably only forms wedge on a row excrescence, do not form wedge on other excrescences.At this moment, be set to from the nearest row of the operating portion of operating body as long as form the excrescence of wedge, the sense of movement of operating body is just good especially.

In addition, as long as form the covering part that covers all planes of disruption of said fixing contact pin on above-mentioned excrescence, fixed tabs just is not easy to be corroded, and reliability just can be improved.

As the cone that enlarges to above-mentioned base bottom surface is set in above-mentioned covering part, folder shape activity contact pin assembles just than being easier to excrescence.

With reference to the accompanying drawings embodiment is described.

Fig. 1 is the longitudinal section of the skate Switch of the first embodiment of the present invention,

Fig. 3 is the cross-sectional view of the skate Switch of an alternative embodiment of the invention.

As shown in the figure, be open box-shaped above the plastic pedestal 1, erect in its bottom surface plurality of fixed contact pin 2 is set.These fixed tabs 2 are copper coins that noble metal has been plated on the surface, and protruding in pedestal 1 following part is fixed tabs end 2a.Fixed tabs 2 is configured to two row in pedestal 1, separate certain interval between each row.In the inside of pedestal 1, correspond to each fixed tabs 2 and form the parallel excrescence 3 of two row, these excrescences 3 are integrated with it when pedestal 1 dress fixed tabs 2.Each fixed tabs 2 is exposed in the one side of excrescence 3, the part except this exposes face, and the complete rupture face on promptly comprising all is highlighted body 3 and covers.Form some wedge 3a in the another side of excrescence 3, form narrow cone 3b in the upper end of excrescence 3.

The top open end of said base 1 covers with the cover plate 4 of metallic plate system, and the operating body 5 of molding synthetic resin can reciprocatingly be set between cover plate 4 and the pedestal 1.On this operating body 5, form a pair of recess 5a, protrude in the pinch hand 5b of pedestal 1 outside simultaneously in formation.Folder shape activity contact pin 6 remains among each recess 5a, to ground some contact 6a is set relatively in each activity contact pin 6.Whippy materials such as these activity contact pin 6 usefulness phosphor bronzes are made, and insert in the mode of seizing above-mentioned excrescence 3 two sides on both sides by the arms.

Below, the action of the switch of above-mentioned structure is described.During the pinch hand 5b of the operating body 5 that highlights from pedestal 1 with finger manipulation as the operator, the activity contact pin 6 that operating body 5 is keeping is moved to the length direction of this excrescence 3 under the state of seizing excrescence 3 on both sides by the arms.Like this, the contact 6a on one side of activity contact pin 6 contacts selectively, breaks away from plurality of fixed contact pin 2, carries out the switching of open and close, and the contact 6a of the another side of the contact pin of activity simultaneously 6 contacts selectively, breaks away from some wedge 3a, produces the location sense.Like this, the operator can confirm whether the switch change action is finished according to the location sense.Like this, skate Switch according to present embodiment, contact 6a by activity contact pin 6 contacts selectively, breaks away from the fixed tabs 2 that excrescence 3 one sides are exposed, carry out the switching of open and close, the contact 6a of the contact pin of activity simultaneously 6 contacts selectively, breaks away from the wedge 3a that the another side of excrescence 3 forms, and produces the location sense, so can save the reed that produces noise made in coughing or vomiting clatter sound, reduce cost, realize miniaturization.In addition, cover because the complete rupture face of fixed tabs all is synthesized resinous excrescence 3, so fixed tabs 2 just is not easy to be corroded, reliability just can be improved.Also have, owing to formed narrow cone in the upper end of excrescence 3, so activity contact pin 6 can be inserted excrescence 3 simply, assembly operation is convenient.

Fig. 3 is the cross-sectional view of the skate Switch of the 2nd embodiment of the present invention, is marking same symbol with the corresponding part of Fig. 1, Fig. 2.

In the embodiment shown in fig. 3, on the two row excrescences 3 that are parallel to each other of the inside of pedestal 1 formation, the excrescence 3 of the pinch hand 5b (downside of figure) of close operating body 5 is the same with the foregoing description, form fixed tabs 2 and wedge 3a, but, on the excrescence 3 of the pinch hand 5b of operating body 5 (upside of figure) excrescence 3 far away, only expose fixed tabs 2, do not form wedge 3a.In this case, similarly during the pinch hand 5b of the operating body 5 that highlights from pedestal 1 with finger manipulation as the operator, the activity contact pin 6 that operating body 5 is keeping is under the state of seizing excrescence 3 on both sides by the arms, move to this prominent length direction by body 3, the contact 6a of activity contact pin 6 contacts selectively, breaks away from corresponding fixed tabs 2, carries out two circuits and switches with the open and close of contact.At this moment produce above-mentioned location sense from the row excrescence 3 that wedge 3a is arranged.Do not have the row excrescence 3 of wedge 3a not produce the location sense, still, the operator can confirm whether the open and close action is finished according to the location sense that a row excrescence 3 produces.

Skate Switch according to such structure, except having all effects of above-mentioned the 1st embodiment, can reduce the uncertainty of locating when two row excrescences 3 all form wedge 3a, this is meant, for example stagger in the wedge 3a position between the two row excrescences 3, or the unnecessary location between operating body 5 two circuits that take place to produce when loosening is sympathetic can not produce.Because have the excrescence 3 of wedge 3a to be positioned at those row near the pinch hand 5b of operating body 5, pointed the pinch hand 5b that waits operation by the operator short with the distance of the wedge 3a that produces the location sense, so can make the sense of movement of operating body 5 become better.

In the various embodiments described above, illustrational all is duplex that two row fixed tabs 2 and two activity contact pin 6 are arranged (two-way with) skate Switch, but switch is not limited to duplex, simply connected () or three above also applicable.Particularly, when the switch that is suitable for more than three, though also can on whole excrescences 3, form wedge 3a, as above-mentioned the 2nd embodiment explanation, as only on any one excrescence 3, forming wedge 3a, to passing through the stable beneficial of location sense.

In each above-mentioned embodiment, explanation be the horizontal skate Switch that operating body 5 horizontal directions move, but self-evident, the present invention also goes for the rectilinear skate Switch that operating body 5 vertical direction move.

State bright form more than the present invention and implement, can obtain effect described below.

The excrescence of integrally formed breakwater shape of being seized on both sides by the arms by activity contact pin in plastic pedestal, the one side of this excrescence is exposed fixed tabs, and another side forms wedge.Like this, on the excrescence of the breakwater shape of being seized on both sides by the arms, need only and form wedge by activity contact pin, when with the folder shape activity contact pin of operating body interlock when excrescence moves, the fixed tabs that activity contact pin is just simultaneously exposed excrescence is hung selectively and is touched, breaks away from, and carries out the change action of open and close, simultaneously wedge contact, the disengaging that the excrescence another side is formed, produce the location sense, so can save the reed that produces noise made in coughing or vomiting clatter sound, reduce cost, realize miniaturization.

As the cone that enlarges to above-mentioned base bottom surface is set in above-mentioned covering part, activity contact pin 6 can be inserted excrescence 3 simply, assembles just than being easier to.

Also have to form some listing when stating excrescence for multiloop, form wedge as therein row only, other excrescence does not form wedge, just can each loop between the difference of location sense, can produce stable location sense.At this moment, be arranged on the position of the operating portion of close operating body as the excrescence that will form wedge, the sense of movement of operating body is just good especially.
