Description

[Detailed description of the invention] This invention relates to a portable light powered by multiple dry batteries.
In particular, the present invention relates to a portable electric lamp with an improved locking structure between a reflector and a white bulb board.

Conventionally, this type of portable electric light has been constructed in such a way that a reflector is provided with a rotatable substrate so that the battery can be replaced simply by unscrewing the lens frame.

FIG. 1 is an enlarged sectional view of the main parts of such a conventional portable electric light, in which 1 is a reflector, 2 is a socket fitting having a threaded part 3 and a flange part 4, and 5 is a threaded part 6 and a flange part 7. 8 is a space inside the light bulb holder 5 at the rear of the white bulb 13; 9 is a substrate to which the contact plates 8, 9, and 10 are fixed; 1;
4 is a battery set consisting of a plurality of batteries.

As is clear from Figure 1, the conventional portable light has a reflector 1.
A socket fitting 2 having a threaded part 3 and a collar part 4 in the center of the socket fitting 2.
and is screwed onto the socket fitting 2.
The light bulb holder 5 is provided with a threaded part 6 at the front of the outer periphery and a collar part 7 at the rear, and between the threaded part 6 and the collar part 70, the battery assembly 1 is provided.
By screwing the light bulb holder 5 to the socket fitting 2, the reflector 1, it has a structure in which the substrate 9 can be rotated.

However, in such a structure, not only is it expensive to form the threads on the socket metal fitting 2, but also the unscrewing and screwing of the socket metal fitting 2 and the light bulb holder 5 is complicated, and the light bulb Since the flange 7 of the holder 5 is difficult to grip, there are problems such as difficulty in unscrewing when replacing the white bulb.

In addition, since the structure is such that conduction is established from the contact plate 12 provided on the board 9 to the white bulb 13 via the socket metal fitting 2, the contact plate 12 and the collar part 4 of the socket metal fitting 2, which has become slanted due to the board 9 being twisted, are connected to each other. Another drawback was that the contact was poor and the light sometimes did not light up.

Therefore, the purpose of the present invention is to eliminate the drawbacks of the above-mentioned prior art,
A new mobile light that allows the reflector and board to be attached and detached to replace white bulbs by simply inserting and pulling them out, as well as ensuring electrical connections and further reducing costs. It is about providing.

In order to achieve this purpose, the present invention includes a reflector, a first flange that is inserted through the center of the reflector and fixed, and whose front end is bent inward, and a rear end that is bent outward. The socket fitting is made of electrically insulating resin, and has a second flange part that overhangs the outer periphery of the second flange part with its outer periphery facing inward. A substrate comprising a white ball holding part facing the first flange, and a detachable protrusion formed around the external force to be rotatably and detachably fitted to the second flange of the socket metal fitting; A pair of contact plates fixed to the substrate, one end of which is in conductive contact with the electrode of the white bulb in the white bulb holding portion of the substrate, and the other end of which is guided to the electrode of the battery arranged behind the substrate. This is a configuration of a characteristic portable light.

Hereinafter, the present invention will be described in more detail with reference to the drawings.

FIG. 2 is a sectional view of a portable electric lamp according to an embodiment of the present invention, and FIG. 3 is an enlarged sectional view of the main part of FIG. 2.

In each figure, reference numeral 21 denotes a main body with a handle on the top, an opening at the front, a thread 22 on the outer periphery of the front, a switch 23 behind it, and a battery assembly 14 inside;
5 is a □ lens frame provided with a thread 26 on the inner periphery and integrated with a transparent lens 27 at the front; 50 is a tail spring that presses and connects the battery sets 14; and 51 is a waterproof ring.

The reflecting mirror 1 has a through hole 30 with a peripheral wall 29 in the center, and its surface is made of resin with a metal coating such as aluminum to make it a highly reflective mirror surface. It is fitted onto the inner surface of the frame 25.

The socket fitting 2 is a cylindrical fitting in which an internal force flange 32 for defining the position of the white ball 13 at the front is integrated with a rear flange 33, and the outer periphery 34 of the external force flange 33 is directed toward the internal force. Its cross section is inverted and bent into a substantially semicircular shape.

The socket fitting 2 is inserted into the center of the reflecting mirror 1 from the rear of the through hole 30, the outer collar 33 is brought into contact with the rear part of the peripheral wall 29, and the outward protrusion 35 is forcibly pushed with an internal twisting jig. The substrate 9 is formed at several places in the peripheral wall 29 to be fixed and fixed to the reflecting mirror 1 by biting into the peripheral wall 29. , is a substrate made of electrically insulating resin provided with second and third contact plates 47, 48, 49, and has an annular white ball holding part 42 that comes into contact with the flange part 38 of the white ball cap 37, which is integrally located approximately in the center. It is set up.

The white ball holder 42 forms a space 8 in which the base 37 of the white ball 13 is housed, and also has a notch 41 formed in a part of the peripheral wall. A locking portion 45 is rotatably attached to and detachable from the outer peripheral portion 34 of the outer collar 33 of the socket fitting 2 fixed to the socket fitting 2.
There are several attachment/detachment protrusions 44 on the circumference, and in order to prevent the board 9 from being damaged or deformed due to external forces such as impact, there are annular attachment/detachment protrusions 44 whose tips abut against the rear surface of the reflector 1. A supporting rib 46 is provided.

Note that the white bulb holder is arranged such that one end of the first contact plate 47 is pressed into contact with the single-power terminal of the battery assembly 14, and the other end is pressed into contact with the side surface of the base portion 37 which becomes one terminal of the white bulb 13. 42
is provided to protrude from the notch 41 into the space 8,
The second contact plate 48 is provided so that one end is in pressure contact with the other terminal of the battery assembly 14 and the other end is in pressure contact with the switch 23, and the third contact plate 49 is provided with one end in pressure contact with the switch 23. , and the third contact plate 49 protrudes to the rear of the space 8 so that one end is pressed against the switch 23 and the other end is pressed against the solder portion 39 which is the other terminal of the white bulb 13. It will be established.

According to this configuration, when the attachment/detachment protrusion 42 of the substrate 90 is externally fitted onto the outer peripheral portion 34 of the external force collar 33 of the socket fitting 2 fixed to the reflecting mirror 1, the substrate 9 is rotated to the rear of the reflecting mirror 1. It is held freely, and the attachment and detachment of the reflecting mirror 1 and the substrate 9 can be performed with a one-touch operation of only press-fitting and pulling-out operations.

Therefore, not only is it easy to replace the battery, but in this case, the outer periphery 34 of the external force collar 33 of the socket fitting 2 is formed with its cross section bent in a substantially semicircular shape toward the internal force. The insertion and removal operations are extremely easy, and the white bulb 13 can be replaced immediately.

Therefore, in the portable electric lamp of this embodiment, when replacing the white bulb, for example, by first unscrewing the lens frame 25 from the main body 21, the reflector 1 and the substrate 9 can be removed together.

Since the substrate 9 can be removed by simply attaching the reflecting mirrors 1 to 9, it is extremely simple, unlike the conventional case where the flange of the light bulb holder is screwed off.

Further, the electrical connection is different from the conventional case where the contact is made through the socket fitting 2, and the battery assembly 14 and the switch 23 are electrically connected to each other.
Since electrical connection is made by directly pressing the connection plate against the white bulb 13, it is possible to reduce the number of contact parts and reduce troubles due to poor contact.

Furthermore, since the socket fitting 2 of this embodiment does not require the formation of a thread, production costs can be reduced, and since a light bulb holder is not required, the number of parts can also be reduced.

As described above, according to the present invention, a reflector to which a socket fitting whose outer periphery is inverted and bent inward is fixed, is rotatably attached to and detachable from the white bulb holder and the outer periphery of the socket fitting on the outside thereof. The reflector and the substrate can be attached and detached by integrally forming a plurality of attachment/detachment protrusions that circumscribe them and support ribs on the outside, and fitting a substrate with a conductive contact plate fixed to the main part. It is extremely easy to replace the battery, as well as the white bulb, and the number of contact parts is reduced, ensuring a reliable electrical connection.Furthermore, there is no need to form threads on the socket fitting, and It is possible to obtain a portable electric lamp having many features such as being able to reduce costs because the number of parts can be reduced.
