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 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 in a U-shaped cross section, a pair of elongated holes are formed on both side surfaces of the metal plate, and tapered surfaces inclining inward at both ends of the metal plate. And a fuse receiving fitting with an arc-shaped support for holding both ends of a cylindrical fuse or a straight tube lamp, and an engaging projection with a pair of locking recesses facing the long hole of the receiving fitting. A fuse box body made of an insulating material is formed by providing a plurality of pairs of rectangular through holes provided on the side edge of the fuse receiving body mounting portion of the fuse box body and allowing the receiving bracket to be mounted from the lower surface. By providing an engaging projection with a recess for locking on the side edge of the mounting part through hole of the mounting part, and by providing a long hole to be fitted to this projection on the side surface of the metal fitting of the fuse or straight tube lamp, One side fits into the engaging recess of the engaging projection A fuse box which is characterized by being configured to be able to removably engage the fuse pivot bracket.

[0004]

Therefore, when this prior art is used as a straight tube lamp socket, there is no light reflecting plate for reflecting the light emitted from the lamp, so that it must be attached separately, and the mounting top surface is inconvenient. In addition to the problem
Installing a fuse or straight tube lamp bracket on a conductive plate such as a body or chassis requires a special insulating bush to be inserted into the fuse or straight tube lamp bracket, which is complicated and poor in workability. It was

Further, since the contact portion of the fuse and the bracket of the straight tube lamp generates heat due to 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 reflection 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.

[0007]

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. Two connecting tools in which a pair of protrusions and an elastic conductive plate are molded into a substantially U shape and integrally provided with a pair of sandwiching pieces and a light reflecting plate, and a conductive member is conductively fixed, and these two connecting tools. Is a mounting hole formed in the base of the sandwiching piece in a direction in which the light reflectors face each other, and a connector assembly mounted between the facing pieces via the protrusions, respectively, and a plane contour of the insulating base. And a mounted object with a large attachment hole formed on the It can be achieved by attaching at the attachment hole in the mounting member in the Kigakaritome hook piece and Tsubahen.

[0008]

When the outer surface of the locking hook piece of the insulating base body is press-fitted between the edges of the attachment hole of the mounted body, the side piece bends in the direction in which the side piece escape hole narrows against its elasticity. , 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 attachment body in a so-called "cassette pon" type. Can be easily installed.

In this mounted state, the vertical movement of the insulating base body with respect to the mounted body is such that the hook edge of the locking hook piece and the upper surface of the collar piece are in contact with the upper and lower surfaces of the mounted body, respectively. It can be regulated and will not rattle. Further, the horizontal movement of the insulating substrate can be regulated by the peripheral edge of the attachment hole of the attached body, and there is no rattling.

A straight tube lamp is integrated into a single connecting tool by crimping or soldering a pair of sandwiching pieces and a conductive member such as a small-width conductive plate or a flat bush surface of a metal round bar to be integrated.
It can be held and held tightly by a pair of holding pieces, and at the time of use, the light from the lamp can be reflected in a desired direction by the light reflecting plate m formed integrally with the connector, and efficient illumination can be performed. Further, since the connector mounting structure, that is, the connector assembled structure, surrounds the two connectors with the insulating base, the two connectors can be mounted through the base with good compatibility regardless of the conductive plate or the insulating plate. .

A gap is formed between the facing piece 3 of 3b and the punching ribs 18, 18 for obtaining a chimney effect for heat dissipation.

The connecting tool 7 has a structure shown in FIG.
7 and FIG. 7 are shown in the projections 4 and 4 in which the mounting holes 8 and 8 formed at the bases of the pair of holding pieces 5 and 5 are provided so as to face the facing piece 3 of the connector insertion hole 3b of the insulating base body 1. After the state shown in FIG. 8, the elasticity of the holding pieces 5, 5 is used to snap in and mount as shown in FIG. 9 to make a connector assembly 9 as shown in FIG.

The light reflecting plates m are mounted so that there is a gap of about 1 mm between the opposing parts.

Further, the attached body 11 is made of a plastic or metal plate and has an attachment hole 10 slightly larger than the plane contour of the insulating base 1 as shown in FIG. 1 in the attachment hole 10 of the mounted body 11 by the locking hook pieces 2a, 2a and the collar pieces 2b, 2b in the order shown in FIGS.

[0032]

Since the present invention is constructed as described above, it has the following effects. Since a light reflection plate m is integrally formed with a holding type connecting tool for holding the electrode part of a straight tube lamp or a small electric bulb and connecting it to a power source, the light emitted from the lamp is reflected in a desired direction. The first effect is that efficient lighting can be performed in a space-saving and economical manner without separately providing a light reflector on a lamp housing or the like.

Insulating substrate 1 which constitutes connector assembly 9
Since the locking hook piece 2a and the brim piece 2b formed in 1 are firmly formed integrally with the base body side piece 1a, they are mechanically strong and the insulating base body may move unintentionally after mounting on the attached body. Without
It has a second effect that it can be used stably for a long period of time.

Furthermore, the assembled structure of the connection tool 7,7 is a connection tool.
Since 7 and 7 are surrounded by the insulating base 1, there is a third effect that the two connecting tools 7 and 7 can be mounted with good compatibility through the insulating base 1 regardless of a conductive plate or an insulating plate.

Furthermore, the heat-resistant insulating substrate 1 is relatively small in size and requires only a small amount of resin, so that it can be cost-producible even if it is molded from 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 is 2
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
Also, the fifth effect is that the heat dissipation effect of the connectors 7, 7 is excellent and high-density mounting is possible.
