Abstract
An electric tool switch belongs to control switches in the electric field, and comprises a case formed by sealing of an insulation base and an insulation close cover, wherein an anode power input terminal, a cathode power input terminal, a first output terminal and a second output terminal are arranged on the insulation base; the case is internally provided with a contact disjunction mechanism, a positive-negative rotation switching mechanism, a brake protection mechanism and a speed regulation control circuit component; the contact disjunction mechanism comprises a direct-connection static contact pad; a fly-wheel diode is arranged between the direct-connection static contact pad and the anode power input terminal; a first clamping slot is arranged on the direct-connection static contact pad; a second clamping slot is arranged on the anode power input terminal; and two ends of the fly-wheel diode are respectively clamped in the first clamping slot and the second clamping slot. When the electric tool switch is used in the process of assembling the fly-wheel diode, the operation difficulty of millwrights can be reduced greatly, and the case can be prevented from being melted by being heated.
Description
Technical field:
The utility model relates to the control switch in the electric field, specifically is a kind of electric tool switch.
Background technology:
Disclose a kind of name on the China national intellectual property board web and be called " electric tool switch "; Application number is 201020520479.9 utility model patent; This utility model electric tool switch comprises the housing (shell) that is sealed to form by insulator foot and insulative cap; Housing is provided with positive and negative electrode power input terminal and first, second lead-out terminal, is provided with contact disjunction mechanism, rotating changement, brake protection mechanism and speed-regulating control circuit assembly in the housing, and contact disjunction mechanism comprises straight-through static contact; Straight-through static contact is electrically connected with the cathode power supply input terminal through fly-wheel diode; In other words, an end of fly-wheel diode is welded on the straight-through static contact, and the other end is welded on the cathode power supply input terminal.The two ends of above-mentioned fly-wheel diode all are welded on cathode power supply input terminal and the straight-through static contact through solder stick usually; Yet in its welding process, tend to exist following two weak points: 1, for guaranteeing the compact conformation of electric tool switch; It is smaller that the housing intracavity space is generally all made; Therefore, when the assembler used soldering appliance (like electric iron) to be welded on the two ends of fly-wheel diode on cathode power supply input terminal and the straight-through static contact, operation is difficulty; 2, solder stick will just begin fusing usually under the temperature about 300 degree, and so high temperature is long-time with after housing contact, and housing is easy to be melted.
The utility model content:
The technical problem that the utility model will solve is, provides a kind of in the process of assembling fly-wheel diode, can reduce assembler's operation easier greatly, the electric tool switch of avoiding housing to melt because of being heated.
The technical solution of the utility model is; A kind of electric tool switch with following structure is provided: comprise the housing that is sealed to form by insulator foot and insulative cap; Insulator foot is provided with cathode power supply input terminal, negative power supply input terminal, first lead-out terminal and second lead-out terminal; Be provided with contact disjunction mechanism, rotating changement, brake protection mechanism and speed-regulating control circuit assembly in the housing, contact disjunction mechanism comprises straight-through static contact, is provided with fly-wheel diode between straight-through static contact and the cathode power supply input terminal; Wherein, Straight-through static contact is provided with first draw-in groove, and the cathode power supply input terminal is provided with second draw-in groove, and the two ends of fly-wheel diode are stuck in first draw-in groove and second draw-in groove.
After adopting above structure, compared with prior art, the utility model electric tool switch has the following advantages: because the straight-through static contact of the utility model electric tool switch is provided with first draw-in groove; The cathode power supply input terminal is provided with second draw-in groove; Therefore, when the assembler assembles fly-wheel diode, can be directly the two ends of fly-wheel diode be snapped in first draw-in groove and second draw-in groove; In case after fly-wheel diode snapped in, first draw-in groove and second draw-in groove just can be clamped it firmly.We are not difficult to find out through said structure; The utility model electric tool switch saves the operation of using soldering appliance to assemble fly-wheel diode; Thereby greatly reduce assembler's operation easier; Meanwhile, the utility model electric tool switch has also avoided housing to melt because of the high temperature that bears solder stick for a long time.
Description of drawings:
Fig. 1 is the rear perspective structure and shape sketch map of the utility model electric tool switch;
Fig. 2 is the main TV structure sketch map after the utility model electric tool switch is hidden insulative cap;
Fig. 3 is the three-dimensional structure for amplifying sketch map when fly-wheel diode is connected on straight-through static contact and the cathode power supply input terminal in the utility model electric tool switch.
Embodiment:
Below in conjunction with accompanying drawing and embodiment the utility model electric tool switch is done further explain:
Like Fig. 1, Fig. 2 and shown in Figure 3; In this embodiment; The utility model electric tool switch comprises the housing that is sealed to form by insulator foot 2 and insulative cap 1; Insulator foot 2 is provided with cathode power supply input terminal 9, negative power supply input terminal 5, first lead-out terminal 3 and second lead-out terminal 4, is provided with contact disjunction mechanism, rotating changement, brake protection mechanism and speed-regulating control circuit assembly in the housing, and contact disjunction mechanism comprises straight-through static contact 6; Be provided with fly-wheel diode 8 between straight-through static contact 6 and the cathode power supply input terminal 9; Straight-through static contact 6 is provided with first draw-in groove 7, and cathode power supply input terminal 9 is provided with second draw-in groove 10, and the two ends of fly-wheel diode 8 are stuck in first draw-in groove 7 and second draw-in groove 10.In this embodiment; In the described contact disjunction mechanism, except that straight-through static contact 6 parts, other parts are all identical with prior art; And rotating changement, brake protection mechanism and speed-regulating control circuit assembly are also identical with prior art, so no longer this gives unnecessary details.
Above-described embodiment describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Under the prerequisite that does not break away from the utility model design spirit; Various distortion and improvement that those of ordinary skills make the technical scheme of the utility model all should fall in the definite protection range of the utility model claims.
