Description

[Detailed description of the invention] This invention relates to a rechargeable portable light, and in particular, it is designed to allow a rechargeable battery and a printed circuit board with a charging mechanism attached thereto to be easily stored in the light body case, and also to prevent liquid from leaking into the rechargeable battery. The present invention relates to a device that improves safety by preventing liquid leakage from adhering to the charging plug part even if a problem occurs.

Conventionally, this type of portable light has two rechargeable batteries 8', 8' integrated with insulating tape, etc., and a light bulb contact plate 1, as shown in Fig. 7.
9', the transformer 10', the rectifier diode 11', and the low resistance resistors 16' and 16' are connected in advance with the lead wire 29, and the leads are connected to the plug 30 of the second case 1b' and the switch mechanism 31 of the first case la'. After soldering the wire 29, the first case la' and the second case 1b' were integrated.
According to such a conventional example, there were drawbacks such as the complicated work of connecting each lead wire 29 and poor assembly workability.

In order to improve these shortcomings, electrical components can be attached to a printed circuit board and made into a unit, but electrical components that are made into a unit in this way are not flexible, making it difficult to store them inside the lamp case. Assembly workability is not very good.

Furthermore, these rechargeable portable lights use rechargeable batteries such as nickel-cadmium batteries, and these types of rechargeable batteries can withstand overcharging and overdischarging well, and there is almost no need to worry about leakage. However, in the unlikely event that liquid leaks, it may be transmitted through the printed circuit board and short-circuit the charging plug.

This proposal was developed in consideration of these points, and it not only improves assembly workability but also prevents accidents even if the rechargeable battery leaks, thereby increasing safety. be.

Hereinafter, the rechargeable mobile light of the present invention will be explained according to the embodiment shown in the drawings. 1aib is an 11th and second case made of a plastic resin which is divided into upper and lower parts, 2a is a first transparent body made of a colorless transparent resin, 2b is a second transparent body made of red transparent resin, 3 is an electrical component unit, 4 is a sliding plug blade, and 5 is a bottom plate.

In the electrical component unit 3, 6 is a printed circuit board, which has a switch contact surface 7 on the printed pattern surface, and a battery case 9 in which rechargeable batteries 8, 8 are housed.
A slide contact board 14 consisting of a first board 6A on which a transformer 10 and a rectifying diode 11 are attached, an insulator plug receiver 12, and a pair of slide contact pieces 13. ', 13' are attached to the rear end of the printed circuit board 6 at right angles by soldering them to the printed pattern surface. 6B, there are holes 15, 15, etc. for printing holes, and first and second low holes 16a, 16b are formed astride the first substrate 6A and the second substrate 6B. Both ends of each are soldered and fixed.

Further, the battery case 9 has a pair of extension portions 9' at the front.
9' is extended, and a socket board 18 having an upper socket terminal fitting 17a and a lower socket terminal fitting 17b is attached between these extension parts 9', 9'.

And at the ends of these extensions 9', 9' there is a ground plate 1.
9, and these are the first, second, and third lead plates 20a.

20b and 20c, and one end of the upper and lower socket terminal fittings 17a and 17b and the tip of the third lead plate 20c are fixed by soldering to the printed pattern surface of the first board 6A of the printed circuit board 6. A battery case 9 and a light bulb socket mechanism are integrated and fixed to the printer 1 to the board 6.

Next, in the first case 1a, reference numeral 21 denotes a drying part, and this operating part 21 inserts a switch contact piece (not shown) that comes into contact with and separates from the switch contact surface 7 into the first case 1a. have.

Then, the first transparent body 2a and the second transparent body 2b are
The electrical component unit 3 is placed in the front of the case 1b, and the electrical component unit 3 is housed in the second case 1b. is divided into a first substrate 6A and a second substrate 6B.
B is elastically connected to both ends of the first and second low resistance 16a, 16a, and the slide/f contact piece board 14 of the second board 6B is connected to the guide protrusion of the second case 1b. 22 while guiding the first board 6A and the second board 6A.
It can be easily stored in the second case 1b with flexibility between it and the board 6B, and then the first case 1a is placed over the electrical component unit 3, and then the second case 1b is closed. From the cylinder body 23 to the first case 1
a to integrate the first and second cases la and lb, and attach the light bulb 25.25 to the first and second transparent bodies 2a and 2.
It is attached to the light bulb socket mechanism by screwing it into the screw holes 27a and 27b of the earth plate 19 through the insertion holes 26a and 26b of b, and then inserting the elastic light bulb drawer 28 into the cylindrical body 23 to create a rechargeable mobile phone. It completes electric lighting.

The rechargeable portable light of the present invention is as described above, and in particular, in one in which the light bulb, the rechargeable battery, and its charging mechanism are housed in the first and second cases having a two-part structure, the printed circuit board is provided with the rechargeable battery and the charging mechanism. Electronic components are attached, and a slide contact board for supplying power to the electrical components is attached to the rear of this printed circuit board, and the printed board includes a first board to which the rechargeable battery is attached and a second board to which the slide contact board is attached. Since it is divided into two boards and the first board and the second board are connected to each other by a part of the electronic component, for example, a low resistance, it is easy to store the electronic component in the first and second cases. This greatly improves assembly workability, and even if liquid leaks from the rechargeable battery, this leakage will only leak from the first board, and the second board, which has a sliding contact board for power supply, will There is no possibility of leakage between the two substrates, and therefore no short-circuiting of the commercial power applied to the slide contact substrate, thereby making it possible to completely prevent accidents and improve safety.
