Abstract
The invention discloses a flashlight which comprises a flashlight body which is made of insulating material. A tail cover and a light source portion are respectively arranged at two ends of the flashlight body. The light source portion comprises a light source circuit board and a light source which is arranged on the light source circuit board. A conductive sleeve is arranged close to the inner wall of the flashlight body. An anode spring is arranged at the center position of one inner side of the light source circuit board facing the flashlight body in a protruding mode. A spiral cathode spring which gradually opens is arranged on the periphery of the anode spring. One end of the cathode spring is connected with the conductive sleeve in a butt joint mode, wherein the diameter of the one end of the cathode spring is longer. The anode spring is communicated with the light source. The tail cover is provided with a tail cover circuit board. A tail cover cathode spring and shrapnel are arranged on the periphery of the end face of the tail cover circuit board facing the light source, wherein the shrapnel is welded on the tail cover circuit board and in electric connection with the tail cover cathode spring. The shrapnel is connected with the conductive sleeve in the butt joint mode. Due to the fact that the conductive sleeve is arranged on the inner wall of the flashlight body, the flashlight has the advantages of reducing cost compared with all-metal construction and preventing return circuit isolation and bad electric conduction from being caused by oxidation of the flashlight body in the air.

[brief description of the drawings]
Fig. 1 is flashlight cross-sectional schematic of the present invention;
Fig. 2 is flashlight explosive view of the present invention;
Fig. 3 is tail-hood partial enlarged drawing.
[detailed description of the invention]
Now be further described by reference to the accompanying drawings.
As depicted in figs. 1 and 2, flashlight 10 comprises light source portion 100, conducting sleeve 300, stack shell 400 and tail-hood 500.Light source portion 100 and tail-hood 500 lay respectively at the two ends of stack shell 400, and conducting sleeve 300 is close to the inwall setting of stack shell 400.
Light source portion 100 comprises light source circuit board 120 and light source 140 disposed thereon.The surrounding of light source 140 is closely surrounded with heat radiation rack 160, and heat radiation rack 160 screws togather with lamp holder cylinder 180, and light source circuit board 120 and light source 140 are fixed in lamp holder cylinder 180, and lamp holder cylinder 180 is threaded connection with stack shell 400.
The one side of light source circuit board 120 arranges light source 140, another side (towards the one side in stack shell 400) center convexes with the anodal spring 170 being electrically connected with light source 140, periphery is provided with the negative spring 150 that helical form is gradually opened, and one end that negative spring 150 diameters are less is arranged on light source circuit board 120.After light source portion 100 is installed with stack shell 400, one end that negative spring 150 diameters are larger and conducting sleeve 300 butts.
Stack shell 400 adopts insulating materials to make, and conducting sleeve 300 adopts the conductive material such as stainless steel, can adopt the mode of injection mo(u)lding and stack shell 400 to be made into integration, also can make separately after and stack shell 400 be used in conjunction with.The double-decker of stack shell 400 and conducting sleeve 300, on the one hand than adopting all-metal construction to reduce costs, can prevent from causing loop insulate or conduct electricity bad after stack shell 400 is oxidized in air on the other hand.
Tail-hood 500 is threaded connection with stack shell 400.Tail-hood 500 is provided with tail-hood circuit board 520 towards stack shell 400.As shown in figures 1 and 3, the middle part of tail-hood circuit board 520 convexes with the anodal spring 540 of tail-hood, and periphery is provided with spiral helicine tail-hood negative spring 560.Be connected to shell fragment 580 at the edge joint weld of tail-hood circuit board 510, shell fragment 580 is electrically connected with tail-hood negative spring 560 by tail-hood circuit board 520.After tail-hood 500 is installed with stack shell 400, shell fragment 580 and conducting sleeve 300 butts.For uniform stressed and conduction, shell fragment 580 is preferably at least 2 of even setting.
In order to prevent conducting sleeve 300 slippages, conducting sleeve 300 is made as in the one end near light source portion 100 taper that opening increases gradually, and the structure of sleeve 400 is adaptive with it.The other end of sleeve 400 is provided with ring-shaped step 420, turns up in the end of conducting sleeve 300, forms flange, covers on ring-shaped step 420.So, the pyramidal structure of conducting sleeve 300 can prevent that it is from the less one end slippage of opening, and turnup structure can prevent that again it is from the larger one end slippage of opening.This kind of structure need adopt the mode of injection mo(u)lding to make, and now conducting sleeve 300 and sleeve 400 become an entirety, cannot both be split from any one end, must do destructive dismounting if will split.
As another kind of embodiment, conducting sleeve 300 also can be used as coating, is coated in the inwall of stack shell 400.
When after fit on battery 200, the axial length of battery 200 is consistent with the axial length of conducting sleeve 300, to realize positive pole and anodal spring 170 butts, negative pole and tail-hood negative spring 560 butts of battery 200.Whole circuit is:
Battery 200 negative poles-tail-hood negative spring 560-tail-hood circuit board 520-shell fragment 580-conducting sleeve 300-negative spring 150-light source 140;
Battery 200 positive poles-anodal spring 170-light source 140.
With the stack shell 400 of conducting sleeve 300, directly can be used as a part and use, when use, battery directly packs stack shell into, the problem that can come off without worry parts when maintenance.
The above embodiment has only expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
