The specific embodiment:
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, a kind of dual spring conductive structure for battery and wiring board of the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
As Fig. 1, show the whole cutaway view for the dual spring conductive structure of battery and wiring board and an embodiment of torch of the present invention; In the present embodiment, mutual inverted turriform dual spring conductive structure is set between wiring board and battery, described conductive structure makes the conduction of battery and wiring board more reliable; Meanwhile, adopt turriform spring also to make to be difficult for being short-circuited between dual spring; In the present embodiment, the luminescent properties of torch of applying described conductive structure is reliable, use simple, easy operating.
As shown in Figure 2 to Figure 3, the structure of a kind of dual spring conductive structure one specific embodiment for battery and wiring board of the present invention; Comprise lamp body cylinder 500, tail-hood device 600, wiring board 100 and battery 400; Also comprise the first spring 200 and the second spring 300;
The first spring 200 and the second spring 300 are turriform, and the diameter of the tower head end of the first spring and the second spring is all less than the diameter of tower bottom;
The first spring 200 and the second spring 300 are between battery 400 and wiring board 100;
The tower head end of the tower bottom of the first spring 200 and the second spring 300 is positioned at the same side, and the tower bottom of the tower head end of the first spring 200 and the second spring 300 is positioned at the same side;
The two ends of the two ends of the first spring 200 and the second spring 300 contact with positive pole and the negative pole of wiring board 100 and battery 400 respectively.
Preferably, in the present embodiment, the tower bottom of the first spring 200 is connected with the positive pole of wiring board, and the tower head end of the first spring 200 is connected with the positive pole of battery; The tower head end of the second spring 300 is connected with the negative pole of wiring board, and the tower bottom of the second spring 300 is connected with the negative pole of battery.
Preferably, in the present embodiment, the first spring 200 and the second spring 300 are all fixed on the end face of wiring board; Make the fixing more stable of the first spring 200 and the second spring 300, make the assembling of conductive structure more convenient.
Further, the diameter of the tower head end of the second spring 300 is less than the diameter of wiring board 100, and the diameter of the tower bottom of the second spring 300 is less than the diameter of the end face of battery 400.
Further, the diameter of the first spring tower bottom is less than the diameter of the tower head end of the second spring 300;
Further, because the diameter of the second spring 300 tower head ends is less than the diameter of wiring board 100, the diameter of tower bottom is less than the diameter of battery 400 end faces; Like this, just make larger-size the second spring 300 effectively contact with wiring board 100 and battery 400, because the size of the first spring 200 is less than the second spring 300, therefore, can guarantee that the first spring 200 also can contact with wiring board 100 and battery 400 effectively, produce electric action.
Preferably, in the present embodiment, the second spring 300 is looped around the outside of the first spring 200, and is separated with the first spring 200;
Further, in the present embodiment, the center of the first spring 200 end faces and second center of spring 300 end faces and the center of wiring board are on same straight line; Make the first spring 200 and the second spring 300 stressed evenly, and the direction of strain is consistent.
Closer, because the diameter of the first spring tower bottom is less than the diameter of the tower head end of the second spring 300, so the first spring 200 is less than the second spring 300 completely, therefore, can guarantee when the second spring 300 is enclosed within the outside of the first spring 200, completely separated between the second spring 300 and the first spring 200, and because two springs arrange with one heart, avoided departing from and being in contact with one another of causing in compression process, kept normal conduction.
Preferably, in the present embodiment, the first spring 200 and the second spring length approximately equal in the raw time; Make the compression stress being subject to of the first spring 200 and the second spring 300 more impartial, make conductive structure more reliable.
Further, as follows in the specific works principle of the dual spring conductive structure for battery and wiring board of the present embodiment:
As Fig. 2 to Fig. 3, three-dimensional installation diagram and the partial sectional view of the present embodiment; Positive pole on wiring board 100 and turriform the first spring 200 welding conductings; Meanwhile, the turriform second spring 300 welding conductings of the negative pole on wiring board 100 and upside-down mounting.When tail-hood device 600 and lamp body cylinder 500 carry out screw thread while screwing assembling, wiring board 100 promotes turriform the first springs 200 and upside-down mounting turriform the second spring 300 along with tail-hood device 600 rotates, and in the rear compression of contact battery 400; Because the tower head end of upside-down mounting turriform the second spring 300 is fixed on wiring board 100, tower bottom contacts with battery, and, the diameter of tower head end is less than the diameter of tower bottom, therefore,, when the second spring 300 is subject to force compresses, tower bottom keeps the outwards location of (battery 400 end faces); Meanwhile, because the first spring 200 is positioned at the inner side of the second spring 300, and with the contrary placement of the second spring 300, and the diameter of the tower head end of the first spring 200 is also less than the diameter of tower bottom; Therefore, the first spring 200, when being subject to force compresses, keeps the inwardly location of (wiring board 100 end faces); Like this, the first spring 200 and the second spring 300, just guaranteed the location of two-way stable to make the conductive structure of battery 400 and wiring board 100 more reliable; Meanwhile, because the first spring 200 and the second spring 300 are turriform, and are not only mutually inverted but also arrange with one heart, therefore, make to be difficult for being short-circuited between the two; Make the electric conductivity of battery 400 and wiring board 100 also more reliable.
The torch of the present embodiment, has applied the conductive structure described in the present embodiment, and its light source is lasting, reliable, stable luminescent property, and easy operating and use.
Finally it should be noted that obviously, those skilled in the art can carry out various changes and modification and not depart from the spirit and scope of the present invention the present invention.Like this, if within of the present invention these are revised and modification belongs to the scope of the claims in the present invention and equivalent technologies thereof, the present invention is also intended to comprise these changes and modification.
