Description
Technical field
The utility model relates to the accessory of electric tool, especially relates to electric tool switch.
Background technology
Electric tool switch comprises button, push rod and terminal box; Terminal box comprises the base and cover plate that assembling cooperates, and base and cover web wheel exterior feature matches, and button and push rod link and can be installed in the pedestal up and downly; Be provided with moving contact, fixed contact, a pair of firewire binding post and a pair of zero line binding post in the pedestal; A pair of firewire binding post is used to connect the input and the output of live wire, and a pair of zero line binding post is used for the input and the output of zero line, and a pair of firewire binding post lays respectively at the both sides of push rod; Moving contact and fixed contact are connected respectively on the corresponding firewire binding post and clutch cooperates; Its operation principle is to press the button, and it is movable downwards that button drives push rod, and the moving contact that push rod drives in the terminal box touches the fixed contact energized.Otherwise release button, then moving contact leaves fixed contact and cuts off the electricity supply.
Because the binding post in the pedestal must be installed firmly; The prior electric tool switch all is in the hole slot of binding post, to process the screw thread that can be used for fixedly mounting binding post; The processing that is not always the case of firewire binding post and zero line binding post; Can increase the manufacturing cost and the difficulty of processing of electric tool switch undoubtedly, and firewire binding post temporarily can only be continued to use existing mode because of the both sides that lay respectively at push rod and fixes.
Summary of the invention
Make the processing difficulties defective in order to overcome above-mentioned existing electric tool switch, the utility model provides the electric tool switch of simple in structure and easy processing and manufacturing on the basis that keeps original constancy of volume.
The electric tool switch of the utility model; Comprise button, push rod and terminal box, terminal box comprises the base and cover plate that assembling cooperates, and base and cover web wheel exterior feature matches; Button and push rod link and can be installed in the pedestal up and downly; Be provided with moving contact, fixed contact, a pair of firewire binding post and a pair of zero line binding post in the pedestal, a pair of firewire binding post lays respectively at the both sides of push rod, and moving contact and fixed contact are connected respectively on the corresponding firewire binding post and clutch cooperates; A pair of zero line binding post all is positioned at the susceptor edges of push rod homonymy; Be provided with boss and buck plate between a pair of zero line binding post, boss is provided with through hole, and buck plate is plugged in the through hole and its two ends cooperate with corresponding zero line binding post respectively.
The buck plate of the utility model through between two zero line binding posts, boss being set and passing boss; Terminal block is pushed down by boss and is fixed in the pedestal; The zero line binding post that is assemblied on the terminal block is fixed in the pedestal; Save the procedure of processing that in the hole slot of binding post, processes the screw thread that can be used for fixedly mounting binding post, reduced production costs and difficulty of processing, the binding post that also can avoid bringing because of thread abrasion is loosening; And boss can also be spaced from each other two zero line binding posts, prevents that the zero line misconnection from also can make things convenient for the wiring operation of zero line.
The electric tool switch that the utility model further provides, one of which is to being equipped with dividing plate between zero line binding post and the adjacent firewire binding post.Because firewire binding post never can contact with the zero line binding post, must consider the volume of product again and can not increase distance between the two, so it is separated each other, stop short circuit hidden danger through dividing plate between the two.
The electric tool switch that the utility model further provides; Its moving contact comprises moving contact rack, moving contact pendulum and moving contact; Fixed contact comprises stationary contact bracket and fixed contact, and moving contact is fixedly installed on the moving contact pendulum, and the moving contact pendulum is arranged in the pedestal inner chamber and swings at the pedestal inner chamber; The moving contact pendulum is connected to moving contact rack; Moving contact rack be inlaid among the pedestal and its side towards cover plate, fixed contact is arranged in the pedestal inner chamber and cooperates with the moving contact clutch, fixed contact is connected to stationary contact bracket; Stationary contact bracket be inlaid among the pedestal and its side towards cover plate, moving contact rack and stationary contact bracket are connected respectively to corresponding firewire binding post.
Because in original electric tool switch; Moving contact rack and stationary contact bracket in the terminal box all are to be positioned at pedestal on the surface of cover plate direction usually; That is to say that moving contact rack and stationary contact bracket are exposed towards cover plate; If so advance ash in the terminal box, wide of the positive portion that has very big chance to adhere to be deposited in moving contact rack and stationary contact bracket, and then influence its serviceability.The aforementioned techniques scheme has changed moving contact rack and stationary contact bracket at the inner installation direction of terminal box; Moving contact rack and stationary contact bracket are inlaid among the pedestal; Except having firm advantage is installed; And the side of moving contact rack and stationary contact bracket is exposed towards cover plate, and side is compared wide exposed area of positive portion and wanted much little, and the dust that gets in the terminal box can not piled up on moving contact rack and stationary contact bracket; Thereby the service behaviour of electric tool switch is not reduced, and prolong its useful life.
The utility model further provides two kinds of improved electric tool switch technical schemes: be that susceptor edges is provided with groove, side edge thereof is provided with the convex tendon of pegging graft and cooperating with groove; Also or susceptor edges be provided with convex tendon, side edge thereof is provided with the groove of pegging graft and to cooperate with convex tendon.Because the terminal box in the electric tool switch is assembled by base and cover plate two parts; Can there be the slit inevitably in the junction of between; So the dust that produces when electric tool uses gets into terminal box easily from the slit of base and cover plate junction; Influence the performance of electric tool switch when dust stratification is too much, the dust prevention that the prior electric tool switch is taked is that the junction between the base and cover plate adds the rubber dust-proof cushion, but the slit still exists; Slit after rubber wears out in addition enlarges, so dustproof effect is not satisfactory.Aforementioned two kinds of solutions all are to cooperate the sealing that realizes terminal box through the groove at base and cover panel edges place and the grafting of convex tendon; Original sealing property that on the plane, junction of base and cover plate, installs additional the valve rubber of comparing is better; And can use glue that convex tendon is bonded in the groove; Perhaps can use laser that convex tendon is melted in the following process method in the groove; Make between the base and cover plate to connect closelyr, have and to prevent that the dust of kicking up from getting into the inner outstanding effect of terminal box.
Below in conjunction with accompanying drawing and embodiment the utility model is done further explain.
