BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable light in which a conductive spring does not come off a lead plate even when subjected to vibration or the like.

[0002]

2. Description of the Related Art FIG. 6 is a perspective view showing an example of a locking structure between a conductive spring and a lead plate in a conventional portable light.

Conventionally, in a cylindrical portable light, a conductive spring is disposed inside a bottom surface of a main body case, and a lead plate is disposed along an inner peripheral surface of the main body case. At the joint between the spring and the lead plate, for example, as shown in FIG. 6, the end 13a of the lead plate 13 is bent into a cylindrical shape, and the conductive spring 1
The two ends are locked by inserting the end 10a of the zero.

[0004]

However, in this case, when vibration or the like during transportation is received, the conductive spring 10 rotates in the circumferential direction in the main body case and comes off the lead plate 13.
There is a risk that the circuit will break . In particular, the body case
If it is a cylinder with an integral bottom and a bottom,
Check if the spring 10 has come off the lead plate 13
Batteries must be removed from the case to
And the confirmation work is troublesome,
The conductive spring 10 may come off the lead plate 13
There was a strong voice that wanted a portable light with no.

[0005] In view of the above circumstances, the present invention devises a method of locking the conductive spring and the lead plate,
It is an object of the present invention to provide a portable electric lamp in which a conductive spring does not come off a lead plate due to vibration or the like, and the conductive spring and the lead plate can be easily attached.

[0006]

That is, the present invention provides an integrated device.
The main body case has a bottomed cylindrical shape, and a conductive spring (1) is provided inside a bottom surface (2a) of the main body case.
0), and the lead plate (13) joined to the conductive spring is provided in the axial direction along the inner peripheral surface of the main body case. A portion (13a) is formed in a substantially U-shape, and a groove-shaped engaging hole (13b) is formed substantially at the center of the end of the conductive spring at the joining side of the lead plate. 10a) is bent inward, and the end of the lead plate joining side is inserted into the locking hole of the lead plate.

[0007] The numbers in parentheses are for convenience showing the corresponding elements in the drawings, and therefore, the present invention is not limited to the description on the drawings. The same applies to the fields of “claims for registering utility model” and “action”.

[0008]

According to the present invention, the present invention provides a locking device in which the end (10a) of the conductive spring (10) on the lead plate joint side is formed at the end (13a) of the lead plate (13) on the conductive spring joint side. Since the conductive spring is inserted into the hole (13b), the conductive spring acts to restrict the circumferential rotation of the conductive spring.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a sectional view showing an embodiment of the portable light according to the present invention, FIG. 2 is a perspective view of a conductive spring constituting the portable light shown in FIG. 1, and FIG. 3 constitutes the portable light shown in FIG. FIG. 4 is a perspective view showing a state in which the conductive spring shown in FIG. 2 and the lead plate shown in FIG. 3 are assembled, and FIG. 5 shows a joint portion between the conductive spring shown in FIG. 4 and the lead plate. It is a perspective view.

As shown in FIG. 1, the portable light 1 according to the present invention has an integrally molded bottomed cylindrical main body case 2, and an O-ring 7 is provided on the upper side of the main body case 2 in FIG. The lens 6 is screwed. An annular switch 9 is rotatably provided on the outer peripheral surface of the lens 6, and the reflection plate 5 is fitted inside the lens 6. A socket 11 provided with a heat radiating plate 15 is mounted at the center of the reflecting plate 5, and the light bulb 3 is fitted and engaged with the socket 11.

On the other hand, a conductive spring 10 as shown in FIG. 2 is disposed inside the bottom surface 2a of the main body case 2 so as to be extendable and contractible in the axial direction of the main body case 2, that is, in the vertical direction in FIG. Between the spring 10 and the socket 11, two dry batteries 12 can be housed in the main body case 2 in a form connected in series.

A lead plate 13 is provided between the conductive spring 10 and the switch 9 in the axial direction along the inner peripheral surface of the main body case 2. In the joint portion of (1), measures are taken to prevent the conductive spring 10 from coming off the lead plate 13 due to vibration or the like.

That is, as shown in FIG. 3, the lead plate 13 is formed in a U-shape by bending the conductive spring joint side end 13a, and substantially in the center of the conductive spring joint side end 13a. A groove-shaped locking hole 13b is formed in the portion. On the other hand, the conductive spring 10 corresponds to FIGS.
As shown in FIG. 4, the lead plate joining side end portion 10a which contacts the bottom surface 2a of the main body case 2 is bent inward at a substantially right angle, and as shown in FIGS. The side end 10a is inserted into the locking hole 13b of the lead plate 13.

Since the portable light 1 according to the present invention has the above-described configuration, vibrations during transportation of the portable light 1 and the
2, it is possible to prevent the conductive spring 10 from coming off the lead plate 13 due to a circumferential pressure or the like applied to the conductive spring 10. That is, as described above, the conductive spring 10
Since the lead plate joining side end 10a is inserted into the locking hole 13b of the lead plate 13, the circumferential rotation operation is restricted. As a result, the conductive spring 10 does not come off the lead plate 13 even when the portable light 1 receives vibration or the like.

The conductive spring 10 and the lead plate 13
When attaching to the main body case 2, it is only necessary to insert the lead plate joining side end 10 a of the conductive spring 10 into the locking hole 13 b of the lead plate 13 and insert and install them into the main body case 2. , Its installation is easy.

[0017]

[Effects of the Invention] As described above, according to the present invention,
It has a bottomed cylindrical main body case 2 integrally formed , a conductive spring 10 is provided inside a bottom surface 2a of the main body case 2, and a lead plate 1 joined to the conductive spring 10 is provided.
In the portable electric lamp 1 provided with the base member 3 in the axial direction along the inner peripheral surface of the main body case 2, the conductive spring joint side end 13a of the lead plate 13 is formed in a substantially U shape, and the conductive spring joint is formed. A groove-shaped locking hole 13b is formed substantially at the center of the side end 13a, and the lead plate joining side end 10a of the conductive spring 10 is bent inward and the lead plate joining side end is formed. 10a is inserted into the locking hole 13b of the lead plate 13, so that the lead plate joining side end 10a of the conductive spring 10 is formed at the conductive spring joining side end 13a of the lead plate 13. 13b, the rotation of the conductive spring 10 in the circumferential direction is restricted, so that it is possible to prevent the conductive spring 10 from being detached from the lead plate 13 due to vibration during transportation of the portable light 1. It is possible to prevent the.

Further, the end 10a of the conductive spring 10 on the lead plate joining side is inserted into the locking hole 13b of the lead plate 13,
By simply inserting these components into the main body case 2, the mounting on the main body case 2 is completed, so that the mounting is easy.
