BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lamp mounting structure having a light reflecting plate suitable for relay-connecting a straight tube type lamp or a small size lamp to an external connecting member such as a tab terminal.

[0002]

2. Description of the Related Art Many of the connecting devices for this type of lamps and fuses are not equipped with a light reflecting plate, such as the one disclosed in Japanese Utility Model Publication No. 50-36658.

In this prior art, a metal plate having good elasticity and elasticity is bent into a U-shaped cross section, a pair of long holes are formed on both side surfaces of the metal plate, and both ends of the metal plate are inclined inward. The fuse housing bracket is provided with an arcuate support for holding both ends of the cylindrical surface and the tube-shaped fuse or straight tube lamp, and a pair of locking recesses facing the long hole of this bracket. The fitting protrusions are provided on the side edge of the fuse receiving bracket mounting portion of the fuse box body, and a plurality of pairs of rectangular through holes are provided so that the receiving bracket can be mounted from the lower surface. -The main body of the fuse box is provided with engaging projections with locking recesses on the side edges of the mounting hole of the fuse box main body, and on the sides of the fuse and straight tube lamp brackets. By providing a long hole to be fitted to this projection, one side of the long hole fits into the locking recess of the engagement projection. And fuse - fuse, characterized by being configured to be able to detachably engage's pivot bracket - a's box.

[0004]

The above-mentioned conventional technique is to solder a lead wire or the like to the fuse receiving bracket when connecting the receiving bracket of a fuse or a straight tube lamp to another conductive member. Or a strip-shaped narrow conductive plate called a bus bar is connected by caulking.

Therefore, in addition to the problem that this conventional technique requires a connecting tool such as a soldering iron or a crimping tool, the above connecting work is troublesome, and especially, the engine engine
There is a big problem that it cannot be connected in a narrow place such as a frame or in a dark place, and since it does not have a light reflection plate for reflecting the light emitted from the lamp, it needs to be attached separately, and the mounting top is upside down.

In addition to these problems, in order to install a fuse or a straight tube lamp bracket on a conductive plate such as a body or chassis, a special insulating bush is provided for each fuse or straight tube lamp bracket. Since it was necessary to intervene, it was complicated and the workability was poor.

Further, since the contact portion of the fuse and the bracket of the straight tube lamp generates heat by the electric current, there are many problems that the fuse and the entire lamp box need to be made of expensive heat resistant plastic such as 66 nylon. .

In order to eliminate the above-mentioned problems, the present invention integrally forms a light reflecting plate on the connector itself, thereby eliminating the need for a separately provided reflector and not using a connecting tool. Other conductive members can be easily and surely connected to the hugging socket type connecting tool, and the assembled structure of the connecting tool can be attached anywhere with good compatibility regardless of conductive or non-conductive member. The purpose is to do.

[0009]

DISCLOSURE OF THE INVENTION The above-mentioned object of the present invention is to provide an insulating base formed of an insulating material into a substantially rectangular parallelepiped frame shape, and a plurality of locking hook pieces and brim pieces projecting from side pieces of the insulating base. And two pairs of opposed pieces formed by forming side piece escape holes from the inner surface of the side piece on both sides in the length direction of the insulating base, and projectingly provided on the opposed surfaces of these two pairs of opposed pieces. The pair of protrusions and the elastic conductive plate are molded into a substantially U shape, and a pair of sandwiching pieces,
Each of the two connecting tools integrally provided with a plug-in connecting piece and a light reflecting plate and a mounting hole formed on the base of the sandwiching piece in a direction in which the two light reflecting plates face each other. The connector assembly is mounted between the opposing pieces via projections, and the attached body is formed with an attachment hole slightly larger than the planar contour of the insulating base. This can be achieved by attaching the clasp piece and the brim piece to the attached body at the attachment hole.

[0010]

When the outer surface of the locking hook piece of the insulating base body is press-fitted between the edges of the attachment holes of the body to be attached, the side pieces are pushed in the direction in which the side piece escape holes narrow against the elasticity. After that, the side piece returns to its original position when the locking hook piece is disengaged from the edge of the attachment hole, and by one click with the snap, the connector assembly is attached to the attached body in a so-called "cassette pon" type. Can be easily installed with holes.

In this mounted state, the vertical movement of the insulating base body with respect to the body to be mounted is such that the hook edge of the locking hook piece and the upper surface of the brim piece are in contact with the upper and lower surfaces of the body to be mounted, respectively. It is regulated and does not rattle.

Further, the horizontal movement of the insulating substrate is restricted by the peripheral edge of the attachment hole of the mounted body, and it does not rattle.

By integrally forming a pair of holding pieces and a plug-in connecting piece having a plug-in connecting portion in one connecting tool, the straight tube lamp can be held and held tightly by a pair of holding pieces. Light from the lamp can be reflected in a desired direction by the light reflecting plate m, and efficient illumination can be performed. In addition, the tab terminal or the bus bar can be directly inserted into the plug-in connection piece so that the connection can be used. Further, since the attachment structure of the connection tool, that is, the connection tool assembled structure, the two connection tools are surrounded by the insulating base, Through this substrate, two connecting tools can be mounted with good compatibility regardless of whether they are conductive plates or insulating plates.

[0040]

Since the present invention is constructed as described above, it has the following effects.

A light-reflecting plate m is integrally formed with a holding-type connector for holding the electrode portion of a straight tube lamp or a small electric bulb and connecting it to a power source so that the light emitted from the lamp is reflected in a desired direction. Therefore, there is a first effect that efficient lighting can be performed in a space-saving and economical manner without separately providing a light reflector in a lamp housing or the like.

Insulating substrate 1 that constitutes connector assembly 9
Since the locking hook piece 2a and the brim piece 2b formed in the above are firmly formed integrally with the base body side piece 1a, they are mechanically robust and the insulating base body may unintentionally move after being mounted on the attached body. There is a second effect that can be stably used for a long period of time.

Further, the assembled structure of the connecting tool 7,7 is a connecting tool.
Since 7,7 are surrounded by the insulating base 1, this insulating base 1
The third effect is that the two connecting members 7, 7 can be mounted with good compatibility regardless of whether they are conductive plates or insulating plates.

Furthermore, since the insulating base 1 which is heat resistant is relatively small and the amount of resin used is small, it is possible to obtain a sufficient cost even if it is molded with expensive heat resistant plastic. Since it is not necessary to use a particularly expensive heat-resistant plastic for a relatively large mounted insulating plate, there is a fourth effect that the cost is reduced as a whole.

In particular, in the present invention, when a large number of straight tube lamps and small light bulbs are intensively mounted in a narrow space, the number of connecting tools
It is possible to mount the insulating base body 1 that has already been mounted in the mounting hole 10 of the mounted body 11 by the locking hook pieces 2a, 2a in a so-called "cassette pon" type, so that it can be mounted easily and neatly.
Since there are four side piece escape holes 3a, the opposing pieces 3,3 due to convection
The fifth effect is that the heat dissipation effect of the connectors 7,7 is excellent and high-density mounting is possible.

Further, according to the present invention, the tab terminal or the bus bar can be directly inserted into the inserting pinching piece 6 formed integrally with the connecting tool 7 so as to be used, so that the solder required in the prior art is used. There is no need for a trowel or a caulking tool, and the sixth effect is that connection work can be easily performed even in a narrow space such as an automobile engine room or in a dark place.
