Abstract
The utility model provides a switch of reversing, relates to the technical field of switch, by shell, handle, reversing bar, transposition piece, lower contact, terminal, insulating bottom plate, go up contact, insulating upper cover plate and constitute, the terminal dress of lower contact is in the notch on insulating bottom plate both sides. The reversing switch is firm in wiring end and convenient to use.
Description
Affiliated technical field
The utility model relates to a kind of switch, especially a kind of two-direction switch.
Background technology
At present, the terminals that known two-direction switch is contained in the contact on the insulating base on the market stretch out the edge of insulating base, being 90 degree is bent upwards, because stretching out insulating base, can not be fixed a section of its end by this base plate, so when wiring screws screw, because the effect of power, this binding post can produce and shake, and makes terminals insecure; Sometimes when wiring screwed screw, along with the rotation of screw, pad and connector lug also can and then rotate, and used inconvenient.
Summary of the invention
Insecure in order to overcome existing two-direction switch terminals, use inconvenient deficiency, the utility model provides a kind of two-direction switch, and these two-direction switch terminals are firm, easy to use.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of two-direction switch, be made up of shell, handle, reversing bar, transposition sheet, lower contact, binding post, insulating base, upper contact, insulation upper cover plate, the binding post of described lower contact is contained in the recess on insulating base both sides.
Pad on the described binding post is a square washer.
The beneficial effects of the utility model are, because the binding post of lower contact is contained in the recess of insulating base, so when wiring screws screw, this binding post can not shake, and when screwing screw, owing to the square washer of binding post is fixed by recess, so the end of a thread can not followed rotation because of screwing of screw yet, easy to use like this, firmly.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the structure cutaway view after the embodiment two-direction switch goes to cover.
Fig. 2 is the vertical view after the embodiment two-direction switch goes to cover.
Embodiment
Extremely shown in Figure 2 as Fig. 1, transposition sheet 4 is housed on this two-direction switch reversing bar 3, spacer 14, replace between sheet 4 and the transposition sheet 4 and replace and between sheet 4 and the spacer 14 insulated tube 12 is housed all, reversing bar 3 is contained in the middle and lower part of housing 1, the end that reversing bar 3 stretches out housing 1 is equipped with handle 2, the surface on insulating base 7 horizontal both sides respectively is provided with three recesses 16, the vertically middle protuberance that has in the bottom surface of insulating base 7, the central longitudinal of insulating base 7 is to arranging 5 square holes that the corresponding interval distance is arranged, insulating bar 6 is housed in this square hole, insulating base 7 is provided with the contact that 5 pairs of every pair of centres are separated by insulating bar 6, wherein three contacts on every limit have binding post 9, this binding post 9 is contained in respectively in the recess 16 on insulating base 7 both sides, pad on the binding post 9 is a square washer, each hole of insulating base 7 bottom surface protuberances laterally have a groove 13, insulating base 7 is contained in above the transposition sheet 4, transposition sheet 4 tops and groove 13 adapt, roller 5 is housed in the hole of the bottom lug of insulating base 7, the one side of this roller 5 contacts with insulating bar 6 bottoms, another side contacts with transposition sheet 4, insulation cover plate 8 is provided with five lattice space spaced apart from each other, the sheet metal 15 that two ends have the contact is housed in every lattice, spring 11 is housed in the space, one end of spring 11 withstands on the roof in space, the other end of spring 11 withstands on the back side of sheet metal 15, the one side of sheet metal 15 contact-carryings is abutted against on the panel on both sides, space, insulation cover plate 8 is contained on the insulating base 7, the upper contact of insulation cover plate 8 is corresponding with the lower contact of insulating base 7, when switch knob 2 forwards the centre position to, transposition sheet 4 on the reversing bar 3 is by roller 5, insulating bar 6 is risen the sheet metal 15 of insulation cover plate 8, make the upper contact of insulation cover plate 8 separate open circuit with the lower contact of insulating base 7; When switch knob 2 turns to the right side, the transposition sheet 4 of this moment wherein has three darker relatively recesses up, because the effect of insulation cover plate spring 11, upper contact sheet metal 15 will be depressed with three darker corresponding insulating bars 6 of recess, these three pairs of upper contacts 10 are contacted with lower contact, connect circuit; When switch knob 2 ports, its process is same as described above, makes that it reaches separating brake, the purpose clockwise, the reversing of closing a floodgate of closing a floodgate.
Certainly; described insulation cover plate 8 laterally can be with insulating base 7 laterally the same wide; its size, shape and insulating base 7 are complementary; the both sides of insulation cover plate 8 have the recess that adapts with insulating base 7 both sides binding post recesses 16; make insulation cover plate 8 cover binding post 9; the insulation cover plate 8 of binding post 9 screw top correspondences is provided with the hole, can loosen, tighten binding post 9 screws by this hole, and such conversion all drops within the protection range of the present utility model.
Claims (2)
