The above-mentioned prior art is a constant lighting type lighting device using a self-returning push switch, and although it can be used for lighting a passenger compartment such as a trunk room, it cannot be used as an illuminating lamp in a passenger compartment. 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 one-touch connected to a power supply line by 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 form a switch-equipped lamp fitting for blinking a lamp inserted in the socket by a switch connected to a socket opposite to an insulating plate. A sliding piece that is connected to a concave surface formed on the lower surface of the plate and has a knob on the lower surface and a movable contact piece that is self-projecting on the upper surface is placed in an elongated recess with a long hole formed in the center. , A plurality of fixed contact pieces in contact with the movable contact piece are sandwiched between a plurality of support pieces on the lower surface of the insulating plate and temporarily fixed in parallel, and the fixed contact pieces on both sides of the fixed contact pieces are passed through the support pieces. Each of the rising portions is bent outward to form a plug piece, and a bent extension portion of the central fixed contact piece passing through the support piece is connected to one of the sockets, and a plurality of plug pieces are provided between the plug pieces. Of the plug pieces sandwiched between the support pieces The bent extension is connected to the other of the sockets, and the fixed contact piece is located by the switch lid fixed to the upper edge of the elongated recess, and a plug cover integrally formed on the surface of the switch lid is formed in the hole. This can be achieved by inserting the above into the plug pieces and protecting these plugs.

[0006]

[Function] The fixed contact piece and the plug piece are positioned by sandwiching them between the supporting pieces 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 multi-jack.

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.

Further, 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 order to automate each of these operations, each fixed contact piece 6a to 6c is formed by a robot arm or the like which operates based on a series of sequences by well-known means such as microcomputer control.
2 and by gripping the plug pieces 7a to 7c respectively and tightly sandwiching them from the top to the bottom of the insulation plate 1 in the gap between the support pieces against the inherent elastic force of each support piece 3, as shown in FIG. As described above, each fixed contact piece and plug piece can be temporarily fixedly arranged at a predetermined position of the insulating plate 1, and automatic assembly can be executed.

Further, the upper edge of the elongated recess 4 is covered with an insulative switch lid 8 as shown in FIG. 3 through the left and right insertion grooves 3e, 3e as shown in FIG. Inner groove
Fixed contact piece 6a-
6c is positioned as shown in FIGS. 3 and 6, and a plug cover 9 integrally formed on the surface of the switch lid 8 is provided with a hole 9a.
9 to 9c, the plug pieces 7a to 7c are inserted into the plug pieces 7a to 7c as shown in FIGS.

In FIG. 1, the reference numeral 1b is an opposed protrusion formed in the socket insertion hole 1a of the insulating plate 1.
The mounting hole 2c of the socket 2 is fitted into this and the socket is fixed to the insulating plate.

Reference numeral 4a designates an opposite holding piece for inserting the lamp L. Reference numeral 4b designates a long side edge of the elongated recess 4 and knob regulating grooves 4c, 4c are provided on the surface thereof.

Further, reference numeral 5c in FIGS. 5 and 6 is an elastic spring of the movable contact piece 5b provided in the recess 5f of the sliding piece 5, so that 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 the recess 5f of the sliding piece 5 and is moved to the knob regulating groove 4c. Touching.

In FIG. 1, 8b is an insulating plate for the switch lid 8.
Although it is a wedge-shaped protrusion for locking to 1,
8 is wedge-shaped projections 8b, 8b, instead of being locked to the insulating plate 1, as shown by the alternate long and short dash line in FIG.
The switch lid 8 may be fixedly attached to the upper edge of the recess 4 by other known means.

The structure of the present invention is as described above. Next, the operation during use will be described. Fixed contact piece 6a-
6c and the plug pieces 7a to 7c are respectively positioned on the insulating plate 1 as described above, and the fixed contact pieces 6a to 6c are provided.
Is located in the inner groove of the switch lid 8 or the upper edge groove of the recess 4, and the plug pieces 7a to 7c are the holes 9a of the plug cover 9.
Its base can be oriented at ~ 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 or removing a separately installed 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, and the sliding Move the moving piece 5 to move it.
The fixed knobs 6a, 6b or 6b, 6c are short-circuited individually by 5b to switch the lamp L to the switch knob.
It can be turned on manually by 5a or when the door is open.

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

[0025]

Since the present invention is constructed as described above, it has the following effects. Fixed contact piece 6a ~ 6c
Since the plug pieces 7a to 7c and the plug pieces 7a to 7c are fixedly positioned by temporarily sandwiching them in the gaps 3a to 3d of the plurality of support pieces 3 and 3 protruding from the insulating plate, they do not come loose during the assembly process. There is a first effect that it is easy to assemble.

Moreover, the fixed contact pieces 6a to 6c are the switch lid 8
The inner surface of the groove or the upper edge groove of the recess 4
7a to 7c have the second effect that they can be used safely, securely and easily without being delusionally displaced or bent during use because the bases thereof can be localized by 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 attached and removed when the separately installed multi-jack or the like is inserted or removed. There is also a third effect that can be jointed to the power line surely even with one-touch operation.

Further, 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 is stable.
There is a fourth effect that 7a to 7c can be protected.
