Embodiment
As Fig. 4, shown in Figure 5, the utility model four line snap switch mainly by the base 1 of stack successively, two support ends 9 that are placed on base 1 the right and left, two spring contacts 8, left and right sides fixed contacts 7,6 and be placed on middle level dividing plate 5, grounding rack 4, the center 2 above the base 1, the springboards 3 that are placed in the center 2 constitute.
Fig. 6 is the structural representation of base 1.As shown in Figure 5, base 1 is a plastic insulation base, and it is mainly used in two support ends 9 and two spring contacts 8 of placing left and right sides fixed contact 7,6, linking to each other with left and right sides fixed contact.
Fig. 7 is the structural representation that is placed on the support end 9 of base 1 the right and left.Support end 9 is made by conductive metallic material, and as shown in the figure, it is one
The type sheet metal, its end is used to fix binding post 10 for having the sheet metal 91 of " U " type groove, and the other end is used to place spring contact 8 for the sheet metal 92 that has " V " type groove; The two ends of support end 9 are orthogonal.
Fig. 8 is the structural representation that is placed on the spring contact 8 of base 1 the right and left.Spring contact 8 also is to be made by conductive metallic material, as shown in the figure, it for hollow, form by two-layer " V " type sheet metal stack, be respectively equipped with conductive contact 83,84 at the two ends of one deck sheet metal down.
Fig. 9, Figure 10 are the structural representation that is placed on the left and right sides fixed contact 7,6 of base 1 the right and left.As shown in the figure, left and right sides fixed contact 7,6 is
Type conductive metal sheet, an end of sheet metal have " U " type groove 73,63, are used to fix binding post 10; Be respectively equipped with conductive contact 71 and 74,61 and 64 at the two ends of left and right sides fixed contact 7,6, and the conductive contact 71 and 74,61 and 64 that is arranged on the fixed contact two ends lays respectively at the both sides of sheet metal.
As Fig. 5, shown in Figure 6, during installation, left side fixed contact 7 is placed in the groove 12,16, right fixed contact 0 is placed in groove 13 and 14, just long-armed 72,62 of left and right sides fixed contact is placed on respectively in groove 16 and 14, " U " type groove 73,63 that left and right sides fixed contact is used for fixing binding post 10 is placed on groove 12 and 13." U " type groove 91 of two support ends 9 is placed in two grooves 11 and 19 on base 1 top, " V " type groove 92 of two support ends 9 is placed in two grooves 17 and 15 on base 1 top, an end 81 of spring contact 8 points is placed in " V " type groove 92 of support end 9.Shown in Fig. 9,10, because the conductive contact 74 and 71,64 and 61 at left and right sides fixed contact 7,6 two ends lays respectively at long-armed 72,62 the both sides of left and right sides fixed contact, so, when mounted, as shown in Figure 5, conductive contacts 74 above the fixed contact 7 of a left side pass the spring contact 8 on right fixed contact 6, the right, and are corresponding with the conductive contact 84 of the spring contact 8 on the right; In like manner, the conductive contacts 64 above the right fixed contact 6 pass the spring contact 8 on left fixed contact 7, the left side, and are corresponding with the conductive contact 84 of the spring contact 8 on the left side; Here it is, and the utility model four wiretaps can realize being positioned at the reason of the binding post conducting on the diagonal.
In order to prevent that the left and right sides fixed contact 7,6, spring contact 8 and the support end 9 that are placed in the base 1 from rocking, on base 1, place a middle level dividing plate 5.As shown in figure 11, the centre of middle level dividing plate 5 has a square hole 51 that spring contact 8 can be exposed.Also be provided with a plush copper 52 on the dividing plate of middle level, plush copper 52 fixes in the groove 18 of base 1.
As shown in Figure 5, also be pressed with a metal grounding rack 4 on middle level dividing plate 5, the centre of grounding rack 4 also has a square hole 42 that spring contact 8 can be exposed, and it links to each other with earth connection by earthing screw 11 (as shown in figure 12).
As shown in Figure 5, on grounding rack 4, also be placed with a center 2 that is used for ccontaining springboard 3.In order to prevent from when pushing springboard 3, to send the sound of " whip ", between springboard 3 and center 2, be placed with India-rubber spring 30.Have rectangular hole 21 in center 2 and groove 82 corresponding positions in the middle of the spring contact 8, driving levers 31 in the middle of the springboard 3 can be passed on the groove 82 that center 2, grounding rack 4 and central dividing plate 5 be pressed on spring contact 8.
The utility model realizes that the principle of four wiretaps is: as shown in Figure 5, when upwards pushing springboard 3, driving lever 31 on the springboard 3 just make be positioned at base 1 about the top of two spring contacts 8 depress downwards, about above two spring contacts 8 conductive contact 84 just with left and right sides fixed contact 7, conductive contact 74 above 6,64 contact, again because the conductive contact 74 above the left fixed contact 7 is to pass the right that right fixed contact 6 arrives base, conductive contact 64 above the right fixed contact 6 is to pass the left side that left fixed contact 7 arrives base, so, when springboard 3 was upwards pushed, the binding post that is positioned at base 1 lower left 10 that links to each other with left fixed contact 7 was just by left fixed contact 7, conductive contact 74 above the fixed contact of a left side, the spring contact 8 on the right, the support end 9 on the right be positioned at base 1 top-right binding post 10 conductings; In like manner, link to each other with right fixed contact 6 be positioned at base 1 bottom-right binding post 10 by right fixed contact 6, above the right fixed contact conductive contact 64, the left side spring contact 8, the left side support end 9 be positioned at base 1 upper left binding post 10 conductings, realize being positioned at the purpose of the binding post conducting on the diagonal.When springboard 3 is pushed downwards, driving lever 31 on the springboard 3 just make be positioned at base 1 about the bottom of two spring contacts 8 depress downwards, about the conductive contact 71 of conductive contact 83 below the fixed contact of the left and right sides below two spring contacts 8,61 contact, again because left and right sides spring contact 8 is positioned at " V " type groove of left and right sides support end 9, and they all are electric conductors, so the binding post that is positioned at base 1 lower left 10 that links to each other with left fixed contact 7 is just by left fixed contact 7, conductive contact 71 below the fixed contact of a left side, conductive contact 83 below the spring contact 8 on the left side, the support end 9 on the left side be positioned at base 1 upper left binding post 10 conductings; In like manner, link to each other with right fixed contact 6 be positioned at base 1 bottom-right binding post 10 just the conductive contact 83 below the spring contact 8 on the conductive contact 61 below right fixed contact 6, right fixed contact, the right, the right support end 9 be positioned at base 1 top-right binding post 10 conductings; Realize that four wiretaps are positioned at the purpose of the binding post conducting of homonymy.
The above only is preferred embodiment of the present utility model, and protection range of the present utility model is not limited thereto.Anyly all belong within the utility model protection range based on the equivalent transformation on the technical solutions of the utility model.
