The beneficial effect of the utility model is:
1 is simple in structure, and the pin of the electroconductive elastic sheet of the utility model can inject in the corresponding slot, and shell fragment main body and pin all weld during welding; Increased the pin welding; Thereby strengthened the weld strength of electroconductive elastic sheet, it is high to make that the electroconductive elastic sheet pad continues reliability, the long service life of product;
Two sides of 2 shell fragment main bodys are respectively to outer lug; Can increase the surface area of electroconductive elastic sheet like this, thereby make that the extracting space of paster suction nozzle is arranged on the electroconductive elastic sheet, can realize the chip mounter automatic chip mounting like this; Realize the production automation; Compare with artificial paster in the past, enhance productivity, reduce production costs.
Description of drawings
Below in conjunction with concrete accompanying drawing and specific embodiment, the utility model is further elaborated.
Fig. 1 is the overall schematic of the electroconductive elastic sheet of the utility model;
Fig. 2 is the vertical view of electroconductive elastic sheet shown in Figure 1;
Fig. 3 is the left view of electroconductive elastic sheet shown in Figure 1;
Fig. 4 is the schematic perspective view of the electroconductive elastic sheet of the utility model.
Embodiment
Referring to Fig. 1～Fig. 4, a kind of electroconductive elastic sheet comprises shell fragment main body 1, spring leaf 2, and said shell fragment main body middle part is provided with at least one through hole 3, and the root 21 of said spring leaf is connected with the part at the edge of the through hole 3 of said shell fragment main body;
Said electroconductive elastic sheet also includes a plurality of pins 4, and said pin 4 is arranged at the outward flange of said shell fragment main body 1.
In the present embodiment, but as a kind of execution mode, spring leaf 2 is an integral body with shell fragment main body 1, and the root 21 of spring leaf is connected with shell fragment main body 1, and the electroconductive elastic sheet of present embodiment can whole prepare.
Electroconductive elastic sheet generally through reflow soldering on PCB (printed circuit board (PCB)), be assembled into finished product after, for example for the electroconductive elastic sheet that button cell is installed; After installing battery, battery can be exerted pressure to the spring leaf of electroconductive elastic sheet, under long pressure effect; The solder joint that electroconductive elastic sheet is welded on the PCB may sealing-off; The solder joint sealing-off can cause electroconductive elastic sheet and PCB loose contact, and the utility model is provided with pin in the outward flange position of shell fragment main body, and pin is perpendicular to the electroconductive elastic sheet main body; Directly the pin of electroconductive elastic sheet is inserted in the PCB jack during paster; Welding back shell fragment main body and pin all weld with PCB like this, can strengthen the weld strength of electroconductive elastic sheet like this, improve the electroconductive elastic sheet soldering reliability.
Preferably, but as a kind of execution mode, the shape of said shell fragment main body 1 can be various geometries, for example rectangle, triangle, circle or the like; Said pin 4 is vertically installed in the corner location of said shell fragment main body 1.Pin is arranged at the corner location of shell fragment main body, makes things convenient for the processing of electroconductive elastic sheet and follow-up paster, soldering like this.
Preferably, but as a kind of execution mode, said shell fragment main body 1 is a rectangle, and the number of said pin 4 is 4, and said 4 pins are arranged at four jiaos of said rectangle shell fragment main body respectively.The processing of pin for ease, in the present embodiment, described pin is preferably dimensioned to be 0.5-2.0mm; Said pin height depends primarily on the thickness of the pcb board that uses.
Preferably, but as a kind of execution mode, said shell fragment main body 1 is a rectangle, and referring to Fig. 3, Fig. 4, the middle part 22 of said spring leaf is an elastic portion; The free end 23 of said spring leaf is a contact site, and said contact site is parallel with said shell fragment main body.Spring leaf is the position that contacts with battery or other elements, and the root of spring leaf is connected with the shell fragment main body; The middle part of spring leaf is an elastic portion, and elastic portion can move up and down, and spring leaf is better contacted with element, and the shape of elastic portion can be a different shape, and the elastic portion in the present embodiment is trapezoidal; The free end of spring leaf is a contact site, and the contact site in the present embodiment is set to horizontal plane, this be for the surface with habitual electronic component be that horizontal plane adapts.
