Description

[Detailed description of the invention] The present invention has a battery case with an opening at the head.Batteries, light bulb sockets, and reflectors are housed in the battery case through the opening, and then the lens frame is screwed into the opening and fixed. Regarding this type of portable electric lamp, especially one that separates the inside of the battery case into a battery storage part and a lamp body part by a partition member integrated with this light bulb socket, this partition member can be easily positioned inside the battery case. Regarding things that can be stored.

In this type of portable light, it is necessary to bring the power supply lead plate provided on the battery case side into contact with the peripheral terminal provided on the light bulb socket side to establish electrical continuity. Therefore, when storing the light bulb socket in the battery case, it is desirable to have a structure that allows positioning to be performed so that the power supply lead plate and the peripheral terminal are reliably brought into contact and electrically connected.

This idea was made in view of the above-mentioned circumstances.
To provide a portable electric lamp whose light bulb socket can be easily positioned, is highly reliable, and whose manufacturing cost is low.

The portable electric light of the present invention includes a battery case that has a hollow shape with an opening at the head and the tip of the power supply lead plate facing the opening, and a battery case that has a peripheral edge fitted into the inner peripheral surface of the battery case. A light bulb socket having a partition edge that separates the inside of the case into a battery storage part and a lamp body part, and a viewing window on the partition edge for viewing an elastic peripheral terminal attached to the light bulb socket; A notch is provided in which the peripheral terminal is fitted into a rib protruding from the inner circumferential surface of the battery case in a state in which the peripheral terminal is in elastic contact with the power supply lead plate.

By configuring the portable electric lamp as described above, when the partition member is housed in the battery case, positioning for abutment between the peripheral terminal and the power supply lead plate can be easily performed.

Hereinafter, the portable electric lamp of the present invention will be explained based on embodiments shown in the drawings.

Reference numeral 1 denotes a hollow synthetic resin battery case having a head tube 2 with a larger diameter than a body tube 3 and an opening 4 at the head. The negative side of a battery 5 housed in the body tube 3 and a tip 7a of a power supply lead plate 7 which is electrically connected via a switch 6 to this opening 4 face the opening 4.

Reference numeral 8 designates a synthetic resin light bulb socket formed into a concave tube shape, and the socket 8 has a threaded groove 10 on its inner circumferential surface into which the body terminal 9a of the light bulb 9 is screwed, and the battery is inserted from the outer circumferential surface of the socket 8. Inner peripheral surface 1 of case 1
Partition edge 1 having a peripheral edge 11a fitted into a
1 is formed to protrude in the radial direction. Furthermore, 12 is a central terminal formed by bending an elastic conductive plate material, and one end 12a is guided into the concave tube of the socket 8 through an insertion hole 12c drilled near the bottom surface of the light bulb socket 8, and is connected to the tail terminal of the light bulb 9. 9b, and the other end 1
2b is located on the bottom outer surface 8a of the light bulb socket 8 and is electrically connected to the positive electrode side of the battery 5. Reference numeral 13 denotes a peripheral terminal formed by bending an elastic conductive member and partially embedded and fixed in the light bulb socket 8, the tip 13a of which contacts the bottom circumferential edge 9a' of the peripheral terminal 9a of the light bulb 9. As shown in FIG.
Located on the side, this light bulb socket 8 battery case 1
The tip 7 of the power supply lead plate 7 in the fitted state
It is configured to make elastic contact with a. Further, in the partition wall edge 11, reference numeral 14 denotes a viewing window formed in the shape of a round hole in order to visually check the free end 13b of the peripheral terminal 13 from the surface 11c side of the partition wall edge 11. The partition edge 11 may be cut out or formed. Further, on this partition edge 11, 15 connects the free end 13b of the peripheral terminal 13 to the power supply lead plate 7 when the light bulb socket 8 is fitted into the battery case 1.
A notch 17 is recessed in the peripheral edge 11a of the partition edge 11 in order to be positioned in elastic contact with the tip 7a and fitted into a rib 16 protruding from the inner circumferential surface 1a of the battery case 1. This is a knob protruding from the surface 11c of the partition edge 11 in order to extract the battery from the battery case 1.

Reference numeral 18 represents a reflecting mirror, and reference numeral 19 represents a lens frame that holds the lens 20 and is screwed and fixed into the opening 4 of the battery case 1.

and a light bulb socket 8 provided with the partition edge 11
By being fitted into the battery case 1, the body tube 3 portion inside the battery case 1 is inserted into the battery storage section A.
and the head tube 2 portion is separated from the lamp body portion B, respectively.

Thus, for example, when replacing the battery, the portable electric lamp of the present invention is assembled as follows. First, the battery 5 is inserted through the opening 4 of the battery case 1. Next, insert the light bulb socket 8 with the light bulb 9 into its notch 15.
is inserted into the battery case 1 while fitting into the ribs 16. At this time, the operator performs the work while checking the condition of the peripheral terminal 13 from the front side of the partition wall edge 11 through the viewing window 14. That is, the operator visually checks the position of the peripheral terminal 13 and the position of the power supply lead plate 7, and inserts the terminal so that they are in contact with each other, so that the peripheral terminal 13 contacts the power supply lead plate 7 and bends. can be confirmed. After that, the reflecting mirror 18 is inserted, and the lens frame 19 holding the lens 20 is screwed and fixed to the battery case 1.

By positioning and inserting and fixing the light bulb socket 8 in this manner, the peripheral terminal 13 and the power supply lead plate 7 are surely brought into contact with each other, and there is no possibility of conduction failure.

The portable light of the present invention is constructed as described above, and includes a battery case that is hollow with an opening at the head, and the tip of the power supply lead plate faces the opening, and a peripheral edge on the inner circumferential surface of the battery case. a light bulb socket having a partition edge that separates the inside of the battery case into a battery storage section and a lamp body section by fitting the battery case into the light bulb socket, and the partition edge has an elastic peripheral terminal attached to the light bulb socket. Since it is provided with a viewing window for viewing and a notch that is fitted into a rib protruding from the inner circumferential surface of the battery case while the peripheral terminal is in elastic contact with the power supply lead plate, work such as battery replacement is not possible. When inserting the light bulb socket into the battery case, the operator visually checks the status of the peripheral terminals located on the back side of the bulkhead edge from the front side of the bulkhead edge through the viewing window, and inserts the notch in the bulkhead edge into the battery case. With the extremely simple operation of fitting into the rib, the peripheral terminal and the tip of the power supply lead plate can be reliably brought into contact, and the contact can be confirmed.
It is possible to obtain a highly reliable portable electric lamp that is easy to perform battery replacement work, etc. Moreover, there is almost no increase in manufacturing costs by implementing the present invention.
