Abstract
The utility model discloses a trigger type power switch which comprises a switch seat (1), a knife switch seat (2) which is arranged on the switch seat, a knife switch (3) which is rotatablely arranged on the knife switch seat and a contact head (4) which is in rotating contact with the knife switch, wherein the knife switch seat is formed by two clamping pieces, one end of the knife switch is arranged between the two clamping pieces, shaft holes (5) are correspondingly arranged on the clamping pieces, shafts (6) which are arranged in the shaft holes are arranged on the knife switch, one end of each shaft extends out of the clamping pieces and is provided with a lug boss (7), and a spring (8) is supported between the lug boss and the clamping pieces. The utility model can ensure the tight contact of the clamping pieces and the knife switch; the knife switch is not easy to generate electric sparks to cause a heating and oxidizing phenomenon when being electrically connected; and even the knife switch and the clamping pieces are worn, the spring can basically maintain the constant contact pressure of the knife switch and the clamping pieces in a compensable mode to greatly extend the product service life. The utility model has simple structure, low cost and high practicability and popularization value.
Description
Technical field
The utility model belongs to the technical field of electric switch, specifically is meant a kind of handle pulling type mains switch.
Background technology
What generally adopted at the rotating shaft position that the plug-in strip of handle pulling type mains switch in the market is connected with blade base is riveting process, this technology has two defectives: 1. the riveted joint degree of tightness differs, the flexibility that tension can make plug-in strip rotate reduces, the heating oxidative phenomena is caused by owing to loose contact produces electric spark in the rotating shaft position when crossing pine meeting appearance energising; 2. along with the increase of service time, meeting loosening phenomenon occurred because of mechanical wear between plug-in strip both sides and blade base, and contact pressure die-offs, thereby causes loose contact, influences useful life.
The utility model content
The purpose of this utility model is to provide a kind of plug-in strip to be connected with blade base closely, the handle pulling type mains switch of long service life.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: the handle pulling type mains switch, the blade base, the rotation that comprise switch base, be arranged on the switch base are arranged on the plug-in strip on the blade base, the contact that can supply the plug-in strip rotation to contact, described blade base is made up of two holding pieces, described plug-in strip one end is located between two holding pieces, be provided with axis hole on the described holding piece relatively, described plug-in strip is provided with the axle that places axis hole, described shaft extension goes out the outer end of holding piece and is provided with boss, and the top is provided with spring between boss and the holding piece.
Described boss is located at the two ends of axle.
Described boss is the nut that is connected with male thread.
Because the extruding meeting of having adopted above-mentioned structure, holding piece of the present utility model to be subjected to spring is close to from the trend plug-in strip, guarantee that holding piece closely contacts with plug-in strip, be difficult for the generation electric spark when plug-in strip is electrically connected and cause the heating oxidative phenomena.Even plug-in strip and holding piece have wearing and tearing, spring also makes to compensability the contact pressure of plug-in strip and holding piece remain unchanged substantially, can greatly prolong product useful life.Boss is the whole plug-in strip of the Adjustable structure that is connected with male thread and the contact pressure of holding piece, makes things convenient for tightness is controlled at optimum, and the utility model is simple in structure, and cost is low, has very strong practicality and promotional value.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail, but does not constitute any restriction of the present utility model.
Fig. 1 is the front view of handle pulling type mains switch;
Fig. 2 is the right view of handle pulling type mains switch shown in Figure 1;
Fig. 3 is a schematic diagram of removing plug-in strip among Fig. 2.
Embodiment
As Fig. 1, Fig. 2, shown in Figure 3, handle pulling type mains switch described in the utility model, the blade base 2, the rotation that comprise switch base 1, are arranged on the switch base 1 are arranged on the plug-in strip 3 on the blade base 2, the contact 4 that can supply plug-in strip 3 rotations to contact.Described switch base 1 is made as pottery, plastics, bakelite etc. by insulating material, and described blade base 2 is made up of two copper holding pieces, and described plug-in strip 3 is made by copper sheet.One end of described plug-in strip 3 is located between two holding pieces, is provided with axis hole 5 on the described holding piece relatively, and described plug-in strip 3 is provided with the axle 6 that places axis hole 5.Described plug-in strip 3 is that rotate at the center with axle 6, and plug-in strip 3 rotates to contact to contact 4 can realize being electrically connected between blade base 2 and the contact 4.Described axle 6 stretches out the outer end of holding piece and is provided with boss 7, and the top is provided with spring 8 between boss 7 and the holding piece.The extruding meeting that holding piece is subjected to spring 8 is close to from trend plug-in strip 3, guarantees that holding piece closely contact with plug-in strip 3, difficult generation electric spark when plug-in strip 3 is electrically connected and cause the heating oxidative phenomena.Even plug-in strip 3 has wearing and tearing with holding piece, spring 8 also makes to compensability the contact pressure of plug-in strip 3 and holding piece remain unchanged substantially, can greatly prolong product useful life.
Described boss 7 is located at axle 6 two ends, and spring 8 also is two, and each spring 8 withstands on the outside of two holding pieces respectively, such two holding pieces stressed more even, and the polarization that plug-in strip 3 rotates is good.
Described boss 7 is the nuts that are threaded with axle 6.The contact pressure of boss 7 and whole plug-in strip 3 of axle 6 Adjustable structure that are threaded and holding piece conveniently is controlled at optimum with tightness, and this structure also is convenient to assembling in addition.
