Description

[Detailed description of the invention] This invention relates to a battery case that is stored inside the housing of a mobile light, etc., and in particular, the fixing screw that fixes the battery case when it is housed in the housing is attached to a knob for pulling out the battery case from the housing. It is designed to be used for both purposes.

Hereinafter, the battery case of the present invention will be explained based on a portable lamp equipped with the battery case.

Reference numeral 1 denotes a housing of a portable light consisting of a rear case 2 and a lens 3, and houses a light bulb 4, a reflector 5, and a power switch 6 inside.

Reference numeral 7 denotes a storage recess which has an opening 8 in the outer wall of the housing 1, and is surrounded by a battery holding protrusion 9, a battery case positioning protrusion 10, and a power receiving wall surface 11. Sliding contact pieces 12, 12' are provided.

13 is a battery case made of resin with an opening on the top and holds two batteries 1.
4.14 is arranged side by side and has a storage area 15, and a bottom surface 16 of this storage area 15 has a pair of elastic lead plates 17 that are in sliding contact with the pair of sliding contact pieces 12, 12'. ,
17' is attached, and this lead plate 17.17' is brought into contact with the positive and negative electrodes of the battery 14.14.

Further, 18 is an intermediate lead plate connecting the negative and positive electrodes of the two batteries 14 and 14.

Reference numeral 19 denotes a fixing screw that fixes the battery case 13 to the housing 1 from the outside while it is housed in the recess 7, and has a head having a diameter B larger than the diameter A of the loose insertion hole 20 passing through the battery case 13. 21
and a tip screw portion 22 that protrudes rearward from the battery case 13 and has a diameter C smaller than the diameter A of the loose insertion hole 20, and a threaded portion 22 that connects these and is cut at a diameter smaller than the diameter C of the tip screw portion 22. A part of the loose insertion hole 20 is further reduced in diameter to form a connecting shaft 23.
By inserting this connecting shaft portion 23 into the narrow opening portion 24 into which only the screw 3 is loosely inserted, the screw 19 is prevented from coming off, and this tip screw portion 22 is inserted into the battery case positioning protrusion of the recess 7. It is fixed by screwing into the screw hole 25 of the part 10.

Two batteries 14 are placed in the storage section 15 of the battery case 13.
. Fixed inside the body 1, the positive and negative elastic lead plates 17 and 17' are connected to the pair of sliding contact pieces 12 in the storage recess 7.
, 12' to supply power into the housing 1. On the other hand, when replacing the battery, loosen the fixing screw 19 and pull the head 21 of the screw 19, so that the tip screw part 22 comes into contact with the narrow mouth part 24. Since they are in contact with each other, the battery case 13 can be pulled out from the recess 7 of the housing 1.

The battery case of the present invention is as described above, and in particular, it is removably stored in a storage recess formed in the housing, and has a fixing screw that fixes it from the outside while stored in the storage recess.
This fixing screw consists of a head having a diameter larger than the diameter of the loose insertion hole, a tip screw, and a connecting shaft connecting these and having a smaller diameter than the tip screw. Since it is inserted loosely into the narrow part of the hole, the battery case can be pulled out of the housing recess by simply pulling the head of this fixing screw, making it extremely easy to remove the battery case from the housing. It has the effect that it can be carried out.

Furthermore, according to the present proposal, if the fixing screw for fixing the battery case to the housing is also used as the knob for pulling out the battery case from the storage recess, it is necessary to provide a new pull-out knob on the battery case. Therefore, it can contribute to reducing manufacturing costs.
