Description

The key switch of improvement

The utility model relates to key switch, refers in particular to a kind of key switch of improvement.

Key switch commonly used as shown in Figure 6, sub-e1 of JiongXing Duan and the sub-e2 of back JiongXing Duan before the appropriate location, front and back of pedestal C plugs, the vertical pole of sub-e1 of two JiongXing Duans and e2 passes the bottom surface of pedestal C, the side of the preceding sub-e1 of JiongXing Duan is extended hook part e11, extends the body of rod before the side direction of the sub-e2 of back JiongXing Duan to other side end face of the sub-e1 of preceding JiongXing Duan; Shell fragment d is installed in the pedestal C, and the side activity of shell fragment d makes upper casing a contact with the end face of shell fragment d corresponding to the sub-e2 upper limb of back JiongXing Duan; The affixed axostylus axostyle c1 of the trailing edge of pedestal c, axostylus axostyle c1 colludes an end of establishing spring c2, spring c2 in addition end colludes in the opposite side of shell fragment d, make shell fragment d be subjected to the pulling force of spring c2 and dig peak at before the hook part e11 conducting of the sub-e1 of JiongXing Duan; When pushing upper casing a, drive shell fragment d descends and contacts with the body of rod of the sub-e2 of back JiongXing Duan, makes the back sub-e2 of JiongXing Duan touch conducting, forms another starting state.Its major defect is, because member is more, causes and makes time-consuming the taking a lot of work of assembling, and cost is higher; Provide the spring of shell fragment elastic force afterwards easily to get rusty or rupture, make shell fragment can't correctly contact conducting, easily cause malfunction or motionless in use for a long time.

The purpose of this utility model is to provide a kind of key switch of improvement.To pressing down, the prominent point of the body of rod bottom surface of bow both sides is contacted by the arc place in switch inner shrapnel stage casing with the contact lever of pedestal central authorities, overcome the drawback of prior art, reach simple in structure and contact purpose good and easy to use.

The purpose of this utility model is achieved in that a kind of key switch that connects of improvement, by loam cake, drain pan, pressure cap, shell fragment and bearing are formed, inside hook part is respectively established in the both sides of loam cake, collude respectively in the upper limb of drain pan both sides, this loam cake inner edge angle that is inclined upwardly along affixed hook part, start the perforation that button is installed on drain pan central authorities, its upper end contacts with the inner edge of loam cake, it is characterized in that shell fragment is arcuation, end in contact under its end face and the pressure cap, this arcuation place is provided with hollow-out parts, the both side edges of this hollow-out parts connects bow, each body of rod outstanding and extension tool salient point of the both sides of this bow, this shell fragment end is convexly equipped with slightly acclivitous protuberance, and the end face of this protuberance is respectively established prominent point, this bearing is provided with three terminals integral with it and that stretch out the bearing both sides, one side of this shell fragment is fixed in an outer terminal, the termination contact of the protuberance of opposite side and other side, and the body of rod of the tool salient point of this shell fragment is corresponding to the intermediate terminal of bearing.

The protuberance of this shell fragment is the fork arm shape, and respectively establishes prominent point in the bottom surface of this fork arm.

The one side installing luminous secondary body of loam cake, the negative pole of this luminous secondary body is installed on the drain pan, and its positive pole is connected to loam cake inner edge and pressure cap contact jaw.

Major advantage of the present utility model is: have simple in structure and contact effect good and easy to use.

Below in conjunction with preferred embodiment and accompanying drawing the utility model is further specified:

Fig. 1 is a schematic perspective view of the present utility model;

Fig. 2 is a decomposing schematic representation of the present utility model;

Fig. 3 is a combination cross-sectional schematic of the present utility model;

Fig. 4 is a use push action cross-sectional schematic of the present utility model;

Fig. 5 is a use pressed state cross-sectional schematic of the present utility model;

Fig. 6 is the decomposing schematic representation of common features;

Consult Fig. 1-Fig. 3, the utility model is by loam cake 1, drain pan 2, pressure cap 3, shell fragment 4 and bearing 5 are formed, inside hook part 11 is respectively established in the both sides of loam cake 1,12, divide and collude in addition in the upper limb of drain pan 2 both sides, this loam cake 1 inner edge angle that is inclined upwardly along affixed hook part 11, start the perforation 21 that button 3 is installed on drain pan 2 central authorities, its upper end contacts with the inner edge of loam cake 1, it is characterized in that shell fragment 4 is arcuation, 3 times end in contact of its end face and pressure cap, this arcuation place is provided with hollow-out parts 41, the both side edges of this hollow-out parts 41 connects bow 42, each body of rod 43 outstanding and extension tool salient point 44 of the both sides of this bow 42, these shell fragment 4 ends are convexly equipped with slightly acclivitous protuberance 45, the end face of this protuberance 45 is respectively established prominent point 451, this bearing 5 is provided with three terminal 51a integral with it and that stretch out bearing 5 both sides, 52b, 51c, one side of this shell fragment 4 is fixed in an outer terminal 51a, the protuberance 45 of opposite side contacts with the terminal 51c of other side, the body of rod 43 of the tool salient point 44 of this shell fragment 4 is corresponding to the intermediate terminal 51b of bearing 5, the protuberance 45 of this shell fragment 4 is the fork arm shape, and respectively establish prominent point 451 in the bottom surface of this fork arm, it can increase the elastic force and the intensity of the protuberance 45 that shell fragment 4 extended.

Consult Fig. 4-Fig. 5, during use, push loam cake 1 and drive pressure cap 3 to pressing down, make the body of rod 43 of both sides tool salient point 44 of the bow 42 of shell fragment 4 contact conducting with stage casing terminal 51b, the opposite force that when pressing down, is produced by shell fragment 4 again, and protuberance 25 is upspring and cut off, so that then start another operate condition.

The one side installing luminous secondary body (not shown) of loam cake 1 of the present utility model, the negative pole of this luminous secondary body is installed on the drain pan 2, and its positive pole is connected to loam cake inner edge and pressure cap 3 contact jaws.When loam cake 1 pressed down, to touch diode shinny because of the stage casing conducting in the use, and the usefulness of indication is provided.
