BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wedge base valve and a flat fuse attached to a member to be attached together with a connecting tool through a heat resistant flat holder.

[0002]

2. Description of the Related Art As a small lamp using a wedge base bulb, there is a conventional one described in Japanese Utility Model Publication No. 53-1825.

This prior art includes a housing, a lens located in the opening of the housing, a holder attached to the housing, and a wedge base valve supported by the holder, the holder being a U-shaped conductive metal plate. The holder main body is formed by bending the main body, and the mounting piece is formed integrally with the main body so as to extend in the direction opposite to the U-shape. , A center piece and left and right side pieces are provided at the upper and lower sides of the fitting recess so as to face each other, and the holder main body is fitted into the fitting recess formed in the housing, and the U-shaped portion of the holder main body is placed at the center. An indoor small lamp for an automobile, characterized in that it is sandwiched between one piece and both side pieces, and in this state, the attachment piece of the holder body is fixed to the housing together with the connecting conductive plate.

[0004]

In the above-mentioned conventional technique, the wedge base bulb chamber is formed directly in a part of the interior lamp housing, and the connector is inserted to form the interior lamp. In order to prevent rattling due to thermal deformation of the valve holder due to heat generation, it is sufficient to mold the valve holder part with a large volume housing with heat resistant resin, but heat resistant resin is expensive However, there is the first problem that molding is difficult and the cost is high.

Further, the above-mentioned bulb holder and the member around the connecting tool have a complicated structure and require post-processing such as caulking, and it is extremely difficult to automatically assemble an indoor lamp by automatic wiring including automatic insertion of the connecting tool. There was a point.

In order to eliminate the above-mentioned problems, the present invention secures an inexpensive and reliable heat resistant structure by attaching a wedge base valve to a non-heat resistant member via a heat resistant holder, and a connecting tool. The first purpose is to automate the mounting of the holder on the mounted member.

[0007]

DISCLOSURE OF THE INVENTION The object of the present invention described above is to provide two connecting tools, each having a pair of holding pieces and a lead wire at the base, in which the elastic conductive plate is formed in a substantially U-shape. A valve holder is constructed by mounting parallelly between the inner surface of the side and the projecting surface of the base through a projection formed on the inner surface of the side of the rectangular cylindrical frame-shaped insulating base, and the holder is configured to have a planar contour of the insulating base. This can be achieved by attaching to the attached body having a slightly larger attachment hole than the attachment base by means of a locking hook piece that has passed through the side relief hole of the insulating base.

[0008]

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 edge slightly pushes inward against its elasticity and then the locking hook. When the piece disengages from the edge of the attachment hole, the side edge returns to its original position, and the valve holder can be easily attached to the body to be attached by the attachment hole by the one-shot engagement.

In this mounted state, the vertical movement of the insulating base body with respect to the mounted body is restricted because the opposed hook edges of the pair of locking hook pieces are in contact with the upper and lower surfaces of the mounted body, respectively. There is no rattling, and the horizontal movement of the insulating base can be restricted by the periphery of the attachment hole of the mounted body, and one pair of clamping pieces and lead wires are provided in one connecting tool, so that one pair of wedge base valves can be provided. The holding piece can be held tightly and used for holding, and can be used by being electrically connected to another member by a lead wire.

Since the mounting structure of the connecting tool, that is, the valve holder is surrounded by the insulating base, the two connecting tools can be mounted through the base with good compatibility regardless of whether the plate is a conductive plate or an insulating plate.

Two connecting tools 7,7 provided by connecting are sandwiched between the inner surfaces of both side edges 3,3 and the inner surface of the projecting surface 1a in the insulating substrate 1 as shown in FIGS. That is, at this time, after the connector 7,7 is bent inward against the elastic force of the plate piece, the paired projections 4,4 are inserted into the mounting holes 8,8 formed at the base of the connector 7,7. By elastically returning the respective connecting tools 7,7, the connecting tools 7,7 are mounted between the inner surfaces of the respective side edges 3,3 and the inner surface of the base body facing projecting surface 1a as shown in FIGS. 2 and 5, respectively. To form the valve holder 9. In addition, as shown in FIG.
If the projecting ribs 5a, 5a are provided on the protrusion 5, the gripping resilience can be enhanced and the heat dissipation can be improved.

Further, an attachment hole 10 slightly larger than the plane contour of the insulating base body 1 and a large hole 10a connected to the attachment hole are formed on an attached body 11 formed as shown in FIG. The holder 9 is attached to the attached body 11 by the engaging hooks 2 and 2 at the attachment hole 10 as shown in FIG. 6 and each of the figures to form the attachment structure of the connector according to the present invention. .

Further, the attached body 11 near the locking hook pieces 2, 2

Then, as shown in FIGS. 2 and 6, the wedge base valve 12 can be turned on by energizing the lead wires 6, 6 arranged along the surface of the mounted body 11, for example.

A well-known flat fuse may be inserted in place of the wedge base valve 12, but at this time, the valve holder 9 is read as a fuse holder.

[0019]

Since the present invention is constructed as described above, it has the following effects. An elastic conductive plate is formed into a substantially U shape, and a pair of holding pieces 5 and 5 and two connecting tools 7 and 7 each having a lead wire 6 at the base are provided with their mounting holes 8 and 8 to form a rectangular tubular frame-shaped insulating base. The valve holder 9 is constructed by mounting the valve holder 9 in parallel between the inner surface of the side 3 and the projecting surface 1a of the base via the projections 4 4 formed on the inner surfaces of the both sides 3 of the holder 1. Inside the attachment hole 10 by means of locking hook pieces 2, 2 formed on the side 3 of the insulating base 1 on the mounted body 11 in which the attaching hole 10 slightly larger than the plane contour of the insulating base 1 is formed. Can be attached to.

Therefore, even if only the small-volume valve holder 9 is made of expensive heat-resistant resin and the large-volume mounted body 11 is made of inexpensive non-heat-resistant resin, the heat resistance requirements around the lamp and fuse can be secured. The first effect is that the cost can be significantly reduced as compared with the above-mentioned conventional technique in which the resin is molded with an expensive heat-resistant resin, and that it is economical.

Further, in particular, when the outer surface of the locking hook piece 2 of the insulating base body 1 is press-fitted between the edges of the attachment holes 10 of the mounted body 11, the mounting structure of the connector according to the present invention, 3 pushes slightly inwardly against its elasticity, and then the locking hook piece 2 disengages from the edge of the attachment hole 10, so that the side edge returns to its original position by its own elasticity and one click with a snap. Thus, the valve holder 9 can be easily and automatically mounted in the attachment hole 10 of the mounted body 11.

In this mounted state, the mounted body 11
The vertical movement of the insulating substrate 1 with respect to the
The two opposite hooks are in contact with the upper and lower surfaces of the mounted body 11 respectively, so that there is no rattling, and the horizontal movement of the insulating base 1 does not occur at the periphery of the mounting hole 10 of the mounted body 11. It can be regulated, and the locking hook piece 2 formed on the insulating base body 1 that constitutes the valve holder 9 is mechanically robust because it is firmly molded integrally with the base body 1 without moving, and after mounting on the mounted body Since the insulating substrate does not move unintentionally, there is a second effect that the stability during use can be maintained for a long time.

Further, the assembled structure of the connection tool 7,7 is the connection tool 7,
Since 7 is surrounded by the insulating base 1, there is also a third effect that the two connectors 7, 7 can be mounted with good compatibility through the insulating base 1 regardless of whether they are conductive plates or insulating plates.

In particular, in the present invention, when a large number of wedge base valves, flat fuses and the like are intensively mounted in a narrow space, the insulating base body 1 to which two connecting tools are attached is attached to the locking hook pieces 2, 2. The fourth effect is that the mounting can be easily and orderly arranged and mounted in the mounting hole 10 of the mounted body 11, and high-density mounting is possible.

Further, according to the present invention, the wedge base valve or the like can be used while being tightly held and sandwiched by the pair of connecting pieces 5, 5 and the lead wire 6 can be directly connected to another member. Therefore, no caulking tool or the like is required for mounting and mounting at the use site, which was necessary in the above-mentioned conventional technology, while automatic assembly can be performed at the manufacturing site, and it is also possible to use a narrow space such as an automobile engine room. Fifth, connection work can be done easily even in dark places
There is also the effect of.

According to the second aspect, the holding pieces 5, 5 of the connection tool 7 are provided.
The waist can be strengthened and the effect of better heat dissipation can be added.
