Abstract
The invention discloses a leaf spring riveting switch for an automobile and a leaf spring riveting method of the leaf spring riveting switch. The leaf spring riveting switch comprises a metal contact plate and a leaf spring. When the switch is pressed down, a movable contact fixed to one end of the leaf spring makes contact with a stationary contact located below the movable contact so that the switch is switched on, and the other end of the leaf spring is fixed to the metal contact plate through a circular-truncated-cone-shaped flanging on a riveting cylinder on the metal contact plate. The leaf spring riveting switch is simple in structure, convenient to use, practical, capable of effectively solving the problems of looseness and falling-off in the prior art and solving the problems of complex processes and high cost in the assembly process, and capable of being widely applied to various switches.
Description
Technical field
The present invention relates to a kind of spring for automobile sheet riveted joint switch and spring leaf clinching method thereof, belong 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 relying on the switch of 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 structures such as buckle install, 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 problem to be solved in the present invention: 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 and rely on the assembly technology occurring in rivet complicated, the problem that material cost is higher.
Technical scheme of the present invention: a kind of spring leaf clinching method of spring for automobile sheet riveted joint switch, it relates to the riveted joint of Metal Contact sheet and spring leaf, the method disposable assigned address at Metal Contact sheet in the punch forming process of Metal Contact sheet stamps out round platform, 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 after making circle hole sleeve on round platform, press, after pressing, utilize the distortion of round platform flange that spring leaf is directly fixed to Metal Contact sheet.
Spring for automobile sheet riveted joint switch, comprise Metal Contact sheet and spring leaf, when 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.
Beneficial effect of the present invention:
Compared with prior art, the present invention has advantages of following:
1) due between spring leaf and Metal Contact sheet, directly contact, can effectively guarantee 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, because interface unit softens the problems such as loose contact that cause;
3) by the distortion of stamping riveting round platform, form round platform flange 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 the use of little electric current like this, 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 is used.
The present invention 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.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present invention;
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:
A kind of spring leaf clinching method of spring for automobile sheet riveted joint switch, it relates to the riveted joint of Metal Contact sheet and spring leaf, the method disposable assigned address at Metal Contact sheet in the punch forming process of Metal Contact sheet stamps out round platform, 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 after making circle hole sleeve on round platform, press, after pressing, utilize the distortion of round platform flange that spring leaf is directly fixed to Metal Contact sheet.
Referring to figs. 1 to Fig. 4, a kind of spring leaf riveted joint of the present invention switch, adopt punching press in Metal Contact sheet 2 punch forming processes, directly at riveted joint round platform 5 of sheet metal upper punch, when 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.
When 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 present invention, 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.
