Embodiment
Below in conjunction with accompanying drawing switching device of the present invention is described in further detail:
As Fig. 1,2, shown in 4 and 5, switching device comprises pedestal 1, be arranged on the terminal 2 of pedestal 1 bottom, be arranged in the pedestal 1 and with terminal 2 corresponding movable contact springs 3, be arranged on the shell 4 on the pedestal 1, be arranged on the turning handle 5 in shell 4 through holes, stretch out in the through hole of shell 4 upper end of turning handle 5, the Lower Half of turning handle 5 then is positioned at pedestal 1, bottom at turning handle 5 axially offers installing hole 6 along it, be provided with spring 7 and slide bar 8 in the installing hole 6, the end of slide bar 8 is stretched out in the installing hole 6 and is offseted with the upper surface of movable contact spring 3, pedestal 1 bilateral symmetry is provided with the chute 9 of a pair of arc, afterbody at arc chute 9 is respectively arranged with a confined planes 10 that is connected with chute 9 downsides, the guide pillar 11 that is arranged on turning handle 5 both sides is corresponding with chute 9 and confined planes 10 respectively, is provided with back-moving spring 15 between the opening inboard at the high spot at turning handle 5 middle parts and shell 4 tops.
Shown in Fig. 1,2,3 and 7, described arc chute 9 is made up of paired long arc shape sheet 12 and short arc sheet 13 respectively, long arc shape sheet 12 be positioned at short arc sheet 13 above, and be separately positioned on two madial walls of pedestal 1, the tail end downside of short arc sheet 13 is respectively arranged with confined planes 10, confined planes 10 respectively with the guide pillar 11 corresponding cooperations of turning handle 5 both sides.
As Fig. 4,5,6 and 7 show, for being the another embodiment in the above-mentioned switching device, described arc chute 9 is made up of the groove that is opened on pedestal 1 two side respectively, afterbody at arc chute 9 also offers the location notch 14 that is connected with groove downwards, the medial surface of the location notch 14 that is connected with chute 9 is a confined planes 10, confined planes 10 respectively with the guide pillar 11 corresponding cooperations of turning handle 5 both sides.
When this switching device is in off-state, as shown in figs. 1 and 4, because the slide bar 8 of turning handle 5 lower ends is positioned at the rearward end of movable contact spring 3, the effect of turning handle 5 back-moving springs 15, turning handle 5 is subjected to a downward active force with respect to shell 4 top open parts, the guide pillar 11 that can guarantee turning handle 5 both sides is spacing on the confined planes 10 of arc chute 9 afterbodys, prevents the misoperation of switch; When this switching device need use, upwards spur turning handle 5, guide pillar 11 on the use turning handle 5 breaks away from the restriction of confined planes 10 and enters the tail end of arc chute 9, at this moment, rotate turning handle 5, the guide pillar 11 of its bottom slides in arc chute 9, the slide bar 8 that turning handle 5 drives its lower end slips on movable contact spring 3 surfaces, the other end of movable contact spring 3 is contacted with terminal 2, thereby make the switching device closure, shown in Fig. 2 and 5; When switching device needs to disconnect once more to close, as long as backward rotation turning handle 5 is done return motion, when slide bar 8 arrives the afterbody of movable contact spring 3 once more, this switching device will disconnect, simultaneously, be subjected under the elastic force effect of turning handle 5 top back-moving springs 15, the guide pillar 11 of turning handle 5 bottoms slides on the confined planes 10 of its tail side in arc chute 9 once more.
