Description

Push button overcurrent protection device

The utility model relates to a kind of overcurrent protection device, refers to the push-button overcurrent protection device of a kind of mat especially.

Traditional overcurrent protection device is as the United States Patent (USP) case the 3rd of in 1974 bulletin; 846; No. 729; it is to be installed with a upper terminal and a lower terminal in housing; the free end of this lower terminal is to extend upward and be formed with a contact; this upper terminal is connected with a guide card; this guide card is to have a contact to contact the formation path with the contact of this lower terminal; simultaneously; the contact end of this guide card also is connected with a shell fragment that is embedded in this housing, and the position that this protector is suitable in this guide card top also is equipped with a depression bar with a spring, and this guide card can be because of the contact of the high temperature deformation escape lower terminal that current overload produced; cause and open circuit thereby reach purpose of safety; when replying the loop, only need depress depression bar, force it to push this guide card as desire; make the contact of this guide card and the contact of this lower terminal, reply contact condition again.

Though aforesaid overcurrent protection device; the safety function of the automatic escape outage of meeting when having current overload; but on using, reality still have several shortcomings to have much room for improvement; for example; no matter whether this guide card escape, its polarization deficiency might be because of the effect of gravity or the distortion of itself; coming back to original position once again and form path, is this case a fly in the ointment.

Because above-mentioned shortcoming; the present invention does not attain at the overcurrent protection device to improve and use inconvenience; studied improvement energetically; so create the 872 First Five-Year Plan of TaiWan, China application 21 No. six " safety switch construction of preventing over-current "; though this case has been improved the shortcoming of above-mentioned U. S. application polarization deficiency; yet the space that still makes progress on reality is used can more be kept on improving, for example:

1) can't cooperate with thicker panel: the narrower both sides of this safety switch are respectively equipped with the anchor clamps of clip guidance panel, because the restriction of space structure makes this safety switch to cooperate with thicker panel.

2) be subject to the dust and the grunge pollution of working site: for the seesaw that makes this switch is finished the action that opens or closes smoothly, therefore between the perforate of ccontaining this seesaw of this switch case and seesaw certain distance is arranged, make oil stain and dust to enter switch, cause loose contact easily via this slit.

Finger is shorter with the electroconductive elastic sheet distance when 3) operating: this phenomenon can cause the operator to get an electric shock because of the effect or the humidity of static, reduces its coefficient of safety.

4) cause misoperation easily:, often cause misoperation because of operator's false touch switch because the stroke of this switch seesaw action is shorter.

Main purpose of the present utility model provides a kind of guidance panel that cooperates various different-thickness, and can effectively avoid oil stain and contamination by dust, uses the overcurrent protection device that enlarges the scope of application and improve conductive effect.

Another purpose of the present utility model provides a kind of coefficient of safety height, actuating length is long, can effectively avoid the overcurrent protection device of electrostatic interaction and misoperation.

Based on above-mentioned purpose; the technical solution of the utility model is that the seesaw with the conventional current protector is modified to and is extended with a movable block and two pivots; on this Switch main body, set firmly a button portion with an actuating strut again; the center line of this movable block is to align with the center line of this pivot; and form an outward-dipping inclined-plane respectively along the vertical direction of its center line; this button portion includes a holder with a hollow double-screw bolt; this double-screw bolt just can a ccontaining button in when assembling; this actuating strut and a spring; and can cooperate nut that it is fixedly arranged on the panel of different-thickness; simultaneously; make this actuating strut be able in this double-screw bolt, do reciprocating type moving; and the reciprocating of this actuating strut of mat acts on this movable block; make this action plate tilt to the left or to the right, make the action that this switch portion is reached path or opened circuit.

So, the utility model does not cooperate with the control panel of all thickness only, button is a moving linearly in this double-screw bolt again, therefore can reduce to the gap of itself and double-screw bolt minimum, can avoid the pollution of oil stain and dust effectively, length that more can the mat double-screw bolt makes the operator be difficult for because of static or moist the electric shock, and the switching stroke that double-screw bolt extended simultaneously can avoid the operator to produce misoperation because of careless manipulation, and real is a kind of excellent novel creation.

The utility model compared with the prior art advantage and good effect is very obvious.By above technical scheme as can be known, the utlity model has following characteristics:

1, double-screw bolt only need cooperate a nut just can cooperate with the control panel of all thickness, can significantly promote its scope of application.

Therefore 2, button of the present utility model is a moving linearly in this double-screw bolt, the gap of itself and double-screw bolt can be reduced to minimumly, can avoid the pollution of oil stain and dust effectively.

3, the utility model can mat the length of double-screw bolt make the operator be difficult for because of static or moist the electric shock, more the switching stroke that extended of mat double-screw bolt can avoid the operator to produce misoperation because of careless manipulation.

Further specify specific structural features of the present utility model and purpose below in conjunction with accompanying drawing.
