Abstract
The utility model discloses a spring piece riveting switch used for an automobile. The spring piece riveting switch includes a metal contact piece (2) and a spring piece (1). When the switch is pressed, a movable contact (3) contacts a static contact (4) to enable the switch to be conducted, wherein the movable contact (3) is fixed on one end of the spring piece (1) and the static contact (4) is disposed under the movable contact (3). The other end of the spring piece is fixed on the metal contact piece (2) through a circular-truncated-cone shaped flanging on a riveting cylinder (5) on the metal contact piece (2). The spring piece riveting switch is simple in structure, is convenient and practical, can effectively solve problems of loosening and falling-out in the prior art and problems of complex technology and high cost during an assembly process, and can be widely used in various switches.
Description
Technical field
The utility model relates to a kind of spring for automobile sheet riveted joint switch, belongs to vehicle switch technical applications.
Background technology
Rely on the elastic reset characteristic of spring leaf, thereby make the switch of dynamic and static contact contact conducting, we are referred to as clapper-type switch.Because can not only overcoming between contact, clapper-type structure forms arcing because disconnecting moment, cause pitting of contact, can also avoid the bad problem of contact Contact causing because of the carbon deposit in use procedure between contact, so increasing switch starts to select clapper-type structure, especially can be found everywhere especially in the little current switch of milliampere level.
In the switch of dependence clapper-type conducting, in order to make the reliable contact of dynamic and static contact, the fixing particular importance that just seems of installation of spring leaf, and in numerous clapper-type switches, being fixed with of spring leaf utilizes plastics rivet hot distortion to fix, also reliable mounting groove, install that the structure such as buckle installs, also after reliable independently metal rivet Pressing Deformation, spring leaf and contact chip are fixed.But risk loosening, that come off that spring leaf all exists is installed in fixed form at these spring leafs; The mode that relies on rivet, has not only increased material cost, has also increased the complexity of assembling.
Summary of the invention
The technical problems to be solved in the utility model: a kind of spring for automobile sheet riveted joint switch and spring leaf clinching method thereof are provided, to solve the existing mounting structure problem of becoming flexible, coming off that reed easily occurs of being hit by a bullet, and solve the assembly technology complexity occurring in rivet, the problem that material cost is higher of relying on.
The technical solution of the utility model: spring for automobile sheet riveted joint switch, comprise Metal Contact sheet and spring leaf, in the time pressing switch, be fixed on spring leaf wherein one end moving contact be positioned at its below fixed contact contact actuating switch, the other end of described spring leaf is fixed on Metal Contact sheet by the round platform flange on the riveted joint cylinder on Metal Contact sheet.
Above-mentioned spring leaf is more than 1.
Aforesaid riveted joint cylinder is directly punch forming on Metal Contact sheet.
The beneficial effects of the utility model:
Compared with prior art, the utlity model has following advantage:
1) owing to directly contacting between spring leaf and Metal Contact sheet, can effectively ensure the reliability contacting between the two;
2) simultaneously spring leaf directly contacts with Metal Contact sheet, can effectively solve prior art in hot environment or generate heat higher in the situation that, softens the problems such as the loose contact that causes because of interface unit;
3) form round platform flange by the distortion of stamping riveting round platform spring leaf is fixed on Metal Contact sheet, reduced the complexity of technique, and can reduce costs;
4) because spring leaf can be die-cut into 1,1.5,2 etc. according to the switch on difference of load of switch, can meet like this use of little electric current, after can also arranging riveted joint by multi-disc spring leaf, shunt, thereby avoid electric current too large ablation contact and spring leaf, meet the situation that large electric current uses.
The utility model is simple in structure, convenient and practical, can effectively solve the problem of becoming flexible, come off that prior art exists, and the complex process occurring in assembling, the problem that cost is higher.

Fig. 1 is structural representation of the present utility model;
Fig. 2 is spring leaf and the syndeton schematic diagram of riveting round platform;
Fig. 3 is the riveted joint round platform schematic diagram before punching press;
Fig. 4 is the schematic diagram of varying number spring leaf.
Embodiment
Embodiment:
Referring to figs. 1 to Fig. 4, the utility model relates to the riveted joint of Metal Contact sheet and spring leaf, that the disposable assigned address at Metal Contact sheet stamps out round platform in the punch forming process of Metal Contact sheet, on spring leaf, offer and round platform position, big or small corresponding circular hole simultaneously, when both connect, spring leaf is placed on to the top assigned address of Metal Contact sheet, and presses after making circle hole sleeve on round platform, after pressing, utilize the distortion of round platform flange that spring leaf is directly fixed to Metal Contact sheet.
The utility model is in the punch forming process of stamped metal contact chip 2, directly at riveted joint round platform 5 of sheet metal upper punch, in the time of stationary spring 1, riveted joint round platform 5 is put in the installing hole of spring leaf 1 one end and is pressed, utilize the 5 flange distortion of riveted joint round platform that spring leaf 1 is directly fixed on Metal Contact sheet 2, at the other end of spring leaf 1, moving contact 3 is installed.
In the time pressing switch, be fixed on spring leaf 1 wherein one end moving contact 3 be positioned at its below fixed contact 4 contact actuating switch, switch activated.
In the utility model, as shown in Figure 4, spring leaf can be die-cut into 6,1.5 riveted joints 7 of biplate riveted joint according to the switch on difference of load of switch, and the different sheet number such as monolithic riveted joint 8, to avoid the generation of the problems such as electric current too large ablation contact and spring leaf.
Claims (3)
1. a spring for automobile sheet riveted joint switch, comprise Metal Contact sheet (2) and spring leaf (1), in the time pressing switch, be fixed on spring leaf (1) wherein the moving contact of one end (3) be positioned at its below fixed contact (4) contact actuating switch, it is characterized in that: the other end of described spring leaf (1) is fixed on Metal Contact sheet (2) by the round platform flange on the riveted joint cylinder (5) on Metal Contact sheet (2).
2. spring for automobile sheet riveted joint switch according to claim 1, is characterized in that: described spring leaf (1) is more than 1.
