Embodiment
Referring to figs. 1 through Fig. 5, the point driving switch embodiment of the utility model band elasticity pressing piece is described further.
A kind of point driving switch with elasticity pressing piece, comprise switch housing 1, be located at pressing cover 2 and pressing piece body 3 in switch housing 1, described pressing piece body 3 is provided with the cavity volume 31 of movable contact piece 4 and opening, the structure setting in T shape of described movable contact piece 4 profile, this movable contact piece 4 comprises installation portion 41 and contact part 42, described installation portion 41 is placed in and in cavity volume 31, is riveted on pressing piece body 3, the openend of described pressing piece body 3 is provided with shell fragment 5, described shell fragment 5 cross section basic configurations are a day character form structure setting, this shell fragment 5 is provided with the breach 51 for accommodating installation portion 41, described contact part 42 is inconsistent with respect to end face and the shell fragment 5 of installation portion 41 1 sides.The installation portion of movable contact piece 4 41 is inserted in cavity volume 31, by the mode of riveted joint, movable contact piece 4 is connected with pressing piece body 3 is movable again, again the pressing piece body 3 after assembling is fit in switch housing 1, above pressing piece body 3, settle pressing cover 2, when operation point driving switch, press described pressing cover 2 downwards, the pressing piece body 3 that is placed in pressing cover 2 belows is moved downward, due to conflicting one end of rocking arm 6 of pressing piece body 3, and the other end buckle of rocking arm 6 sliding piece 7, and pressing piece body 3 can by controlling, rocking arm 6 makes sliding piece 7 left or swing to the right, reach with this effect that changes circuit open/close states, and pressing piece body 3 is being pressed after rocking arm 6, no matter the left side of contact part 42 or right side contact with rocking arm 6 and produce skew and swing, contact part 42 all can be by shell fragment 5 by its reset, make movable contact piece 4 in the time not being subject to active force, remain the reset mode of ajusting, guarantee the flexibility of switching manipulation.
Described contact part 42 is provided with resistance surface 421 with respect to the other end of installation portion 41, and described resistance surface 421 both sides are equipped with inclined plane 422.When pressing piece body 3 is stressed while pressing straight down, inclined plane 422 has guide effect, is conveniently located at the stressed motion of rocking arm 6 of 42 belows, contact part, is conducive to improve the flexibility of switching manipulation.
The openend of described pressing piece body 3 is provided with erection column 32, and described shell fragment 5 is provided with the installing hole 52 for being connected with erection column 32 eye-splices.Shell fragment 5 is connected with pressing piece body 3 with the eye-splice realization of erection column 32 by installing hole 52, and this easy enforcement simple in structure convenient is fixedly mounted on shell fragment 5 on pressing piece body 3, avoids shell fragment 5 to drop and affects the serviceability of switch.Erection column 32 can be located at the relative both sides of openend, and this structure has improved the installation steadiness of shell fragment 5, makes shell fragment 5 can not produce skew or rotate.
In described cavity volume 31, be provided with the limiting section 33 for limiting movable contact piece 4 pendulum angles.The angle that limiting section 33 swings for limiting movable contact piece 4, avoid pressing piece body 3 stressed when excessive, increase to the amplitude pressing down, make pressing piece body 3 excessive with the juxtaposition metamorphose of rocking arm 6, increased the pendulum angle of movable contact piece 4, make shell fragment 5 bending distortion excessive simultaneously, exceed the field of load of shell fragment 5, thereby reduced the useful life of shell fragment 5 or even directly damaged, therefore limiting section 33 can avoid shell fragment 5 stressed excessive, is conducive to extend the useful life of shell fragment 5.
