The above-mentioned prior art is a constant lighting type lighting device using a self-returning push switch, which cannot be used as a lighting device in a passenger compartment even if it can be used for lighting a trunk room of a passenger car. The connection to the power supply line is inconvenient because it is soldered to the terminal piece, and there is a problem that the terminal piece itself is exposed and is easy to move, unstable and dangerous.

In order to eliminate the above-mentioned problems, the present invention can be turned off at a desired time by operating a slide switch, can be connected to a power supply line by a one-touch operation with a plug-in jack, and has a plug cover integrally formed with a switch cover. The purpose is to securely support the plug base while protecting it with.

SUMMARY OF THE INVENTION The above-mentioned object of the present invention is to construct a switch-equipped lamp for blinking a lamp inserted in the socket by a switch connected to a socket opposite to the insulating plate. The sliding piece with the knob on the lower surface and the movable contact piece on the upper surface is placed in the elongated recess that is connected to the concave surface formed on the side edge of the A plurality of fixed contact pieces contacting the contact piece are arranged in parallel by respectively engaging with the concave surface portions of the side edges,
Further, of these fixed contact pieces, the rising portions of the fixed contact pieces on both sides passing through the concave surface portions are respectively bent outward to form plug pieces, and the rising folds of the central fixed contact pieces passing through the concave surface portions are formed. The bent extending part is connected to one of the sockets, the bent extending part of the plug piece arranged in the concave part between the plug pieces is connected to the other side of the socket, and further engaged with the upper edge of the elongated recess. Position the fixed contact piece with the attached switch lid,
In addition, a plug cover integrally formed on the surface of the switch lid is inserted into the plug piece through the hole to protect these plugs.

[0006]

[Operation] The fixed contact piece and the plug piece are respectively positioned at the rising base portion by the concave surface portion on the side edge of the insulating plate,
Moreover, the fixed contact piece can be located in the inner surface groove of the switch lid or the upper edge groove of the recess, and the plug piece can be located in its base portion in the hole of the plug cover. Therefore, the fixed contact piece does not indiscriminately move due to a disturbance such as sliding contact friction with the movable contact piece, and the plug piece does not stick to the insertion and removal of the separately provided multijack.

Then, the power source positive pole is connected to the plug piece and the plug piece is directly connected to the negative pole, and the plug piece is connected to the power source negative pole via the door switch, and the sliding piece is moved and fixed by the movable contact piece. By individually short-circuiting the contact pieces, the lamps can be turned on manually or when the door is opened.

If the movable contact piece is further moved to a position where the short circuit between the fixed contact pieces is released, the lamp can be constantly turned off in the daytime.

In FIG. 1, the reference numeral 1b is an opposing protrusion formed in the socket insertion hole 1a of the insulating plate 1,
It is for fitting in the mounting hole 2c of the socket 2 and fixing this socket to the insulating plate.

Reference numeral 3a is an opposite holding piece for inserting and fixing the lamp L, reference numeral 3e is a long groove for inserting and locking one side of the switch lid 8, and 3f is a supporting member for supporting the other side of the switch lid 8. The stopper eaves piece 4b is provided with knob regulating grooves 4c, 4c on the longitudinal side edge of the elongated recess 4.

Further, 5c is an elastic spring of the movable contact piece 5b provided in the recess 5f of the sliding piece 5 as shown in FIGS. 5 and 6, and the movable contact piece 5b is pressed against the fixed contact pieces 6a to 6c. As shown in FIG. 7, 5d is a movable protrusion such as a steel ball, and this movable protrusion 5d is an elastic spring 5e provided in a recess 5f of the sliding piece 5 and a knob regulating groove 4c. Is in contact with.

Reference numeral 8a designates a fixed contact piece positioning recess formed in the switch lid 8 as shown in FIGS. 1 and 5, and reference numeral 8b designates wedge-shaped projections 8b and 8b for locking the switch lid 8 to the eaves piece 3f. However, the switch cover 8 has wedge-shaped protrusions 8b, 8b, and eaves pieces 3f, 3b.
Instead of engaging with f, the upper edge switch cover 8 of the recess 4 may be fixed to the upper edge of the recess 4 with set screws n, n as shown by the chain line in FIG. Can be laid down.

The structure of the present invention is as described above. Next, the operation during use will be described.

Fixed contact pieces 6a to 6c and plug pieces 7a to 7c
Are positioned at the concave bases 7a to 7d of the side edge 3 of the insulating plate at the rising bases of these pieces, respectively.
6a to 6c are located in the inner surface groove of the switch lid 8 or the upper edge groove of the recess 4, and the plug pieces 7a to 7c are in the plug cover 9
Its base can be oriented in the holes 9a-9c.

Therefore, the fixed contact pieces 6a to 6c are movable contact pieces.
Disturbances such as sliding contact friction with 5b do not indiscriminately move, and plug pieces 7a to 7c do not grind when inserting / removing the separately provided multijack or the like.

To use this, the plug piece 7b is connected to the positive pole of the power source, the plug piece 7a is directly connected to the negative pole, and the plug piece 7c is connected to the negative pole of the power source via the door switch to slide the plug. Move the moving piece 5 to move it.
The lamp L can be manually turned on or turned on when the door is opened by short-circuiting the fixed contact pieces 6a, 6b or 6b, 6c individually by 5b as shown in FIGS. 8 and 9.

Further, if the movable contact piece 5b is further moved to a position where the short circuit between the fixed contact pieces 6a to 6c is released as shown in FIG. 10, the lamp L can be constantly turned off in the daytime.

[0025]

Since the present invention is configured as described above, it has the following effects. Fixed contact piece 6a ~ 6c
And the plug pieces 7a to 7c are respectively positioned by the concave bases 3a to 3d of the side edge 3 of the insulating plate at the rising bases of these pieces, and the fixed contact pieces 6a to 6c are the inner surface grooves or the recesses of the switch lid 8. Localize with the upper edge groove of 4 and plug piece 7a ~
7c has the first effect that it can be used safely and reliably and easily because its base can be localized in the holes 9a to 9c of the plug cover 9.

In particular, the fixed contact pieces 6a to 6c do not move unintentionally due to a disturbance such as sliding contact friction with the movable contact piece 5b, and the plug pieces 7a to 7c are also attached and removed when the separately installed multi-jack or the like is inserted or removed. There is also a second effect that it can be securely connected to the power line even with one-touch operation.

Furthermore, since the plug cover 9 is integrally formed on the surface of the switch lid 8, it is advantageous in terms of cost, and the plug cover 9 itself does not move unintentionally and the plug piece is stable.
There is also a third effect that 7a to 7c can be protected.
