First capping 216c adopts transparent plastic material to make, and two ends are provided with hook bar, to match make the first capping 218c tabling by hooking bar with the first embeded slot 216b.First capping 216c is used for closing openings 216a.In the present embodiment, the first capping 216c and sidewall 215 are in same plane.
Spring 235 is folded between movable contact spring 234 and the first capping 215c.
Like this, in assembling process, first spring 235 can be loaded, then assemble the first capping 216c spring 235 is closed, and, even if after entirety has been assembled, if find that spring 235 is not in place, also can reinstall after opening the first capping 216c spring 235 is taken out.
In addition, two installation portions 240 are relatively located at sidewall C2 place and the sidewall C4 place of pedestal 210.
In the present embodiment, two installation portions 240 have identical structure, are only described in detail to one of them installation portion 240 at this.
Installation portion 240 comprises: mounting panel 243 and the second capping 244.
Mounting panel 243 is provided with two the second embeded slot 243a.Second embeded slot 243a is formed in the mid portion of the outer wall of mounting panel 243.
Second capping 244 is provided with two groups towards the side of mounting panel 243 and is fitted together to protruding 244a.
Two groups are fitted together to protruding 244a and the second embeded slot 243a fastens.Two groups are fitted together to protruding 244a preset space length separately in the vertical direction.By the second capping 244 and mounting panel 243 tabling, the second capping 244 offsets with mounting panel 243, between the second capping 244 and mounting panel 243, form interconnection,
In the present embodiment, employing lateral connection sheet 40 is communicated with two static contacts 233 in contact mechanism 200, in order to prevent lateral connection sheet 40 outside exposed, is loaded by lateral connection sheet 40 in above-mentioned interconnection, thus lateral connection sheet is isolated from the outside, realize the function of protection against electric shock.
In the present embodiment, the rotating shaft 20 of three contact mechanisms 200 is formed as one, and allows three contact mechanisms 200 link like this.
When needing to be communicated with two adjacent contact mechanisms 200, be connected with adjacent static contact 233 respectively by the two ends of longitudinal brace 40, thus realize the connection of two contact mechanisms 200, and, longitudinal brace 40 can be arranged in the vertical passage of formation between the second capping 244 and mounting panel 243, thus longitudinal brace 40 is isolated from the outside, realize the function of protection against electric shock.
As shown in Figure 1, installation component 300 comprises mounting panel 11, positioning pedestal 12, ratchet 13, cover plate 14, backplate 30 and screw rod 15 respectively.In assembling process, mounting panel 11, positioning pedestal 12, ratchet 13, cover plate 14 are arranged on successively the left end side of rotating shaft 20, backplate 30 is arranged on the another right-hand member side of rotating shaft 20.
The side of backplate 30 is provided with two threaded mounting holes 31, and opposite side is provided with two location notchs 32.Two threaded mounting holes 31 are located at backplate 30 respectively towards on the side of contact mechanism 200, and lay respectively on both ends, left and right.Two location notchs 32 be located at respectively backplate 30 and contact mechanism 200 opposing to opposite side on, and lay respectively on upper and lower both ends, in addition, each location notch 32 is T-shaped, like this, the head of fixed-use bolt is entrenched in location notch 32 and the body of rod with threaded portion is fixed on panel after being passed by location notch 32, thus backplate 30 is fixed on panel.
In addition, the both sides of the center of base plate 211 are respectively provided with installing hole 211a.
Screw rod 15 runs through the installing hole 211a that cover plate 14 is positioned at the same side on the installing hole of the same side and contact mechanism 200 successively, and then, the threaded portion of screw rod 15 screws on the corresponding threaded mounting hole 31 of backplate 30, thus three contact mechanisms 200 are carried out fixing.
The effect of embodiment and effect
Contact mechanism involved by the present embodiment and cam switch, because pedestal has mounting groove, run through groove and sidewall portion, two cams overlay in mounting groove, the support that two structures are identical is located at two respectively and runs through in groove, support is provided with slot, movable contact spring is stuck in slot, each cam rotates under the drive of rotating shaft, make corresponding support drive movable contact spring towards or move away from static contact, movable contact spring directly departs from from static contact, thus to make between the static contact often organized fast conducting or disconnect mutually, therefore, the contact mechanism switch speed of the present embodiment is faster, structure is simple, cost is low.
In the present embodiment, because the structure of two supports is consistent, therefore, the simpler and effect that manufacturing cost is lower of the present embodiment implementation structure.
In the present embodiment, because the first capping encapsulates spring, avoid in assembling process, need, at seal cavity, assembling is carried out to spring and load, thus make assembling more quick, and then reduce human cost.Meanwhile, after assemble if overall, find that spring is not in place, also can by open the first capping by after spring taking-up from new loading, then cover the first capping, do not need to dismantle other any parts, the scrappage of product is lowered.
In the present embodiment, because the central angle of the concave portion of cam is in the scope of 15 degree to 16 degree, therefore, realizes gear switch speed faster, and not easily produce electric arc, prevent contact point from generating heat, avoid the distortion of product.
In the present embodiment, because brace encapsulates by the second capping, prevent it directly outside exposed, therefore the present embodiment realizes electroshock-proof function.
Above-mentioned execution mode is preferred case of the present invention, is not used for limiting the scope of the invention.
