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 via a heat resistant holder together with a connecting tool.

[0002]

2. Description of the Related Art Conventionally, as a device for mounting a straight tube lamp or a glass tube fuse on the ceiling of an automobile, etc.
The microfilm of No. 818 (Japanese Utility Model Publication No. 2-137873) is well known. In this conventional example, a U-shaped holding connector is orthogonally fixed to a rectangular flat frame-shaped valve holder member, and the holder member is attached to an attached body such as a ceiling material of an automobile by using a hooking piece. It is attached.

[0003]

In the above-mentioned prior art, since the U-shaped holding piece 5 is provided so as to be orthogonal to the plane of the flat frame-shaped insulating cylindrical body 1, it projects from the upper surface of the insulating cylindrical body. Holding piece
There is no electrical protection around 5 and therefore
Useless external conductors (drivers and other tools) come into contact with the holding piece 5 and the conductive parts of the straight tube lamp held by the holding piece during vehicle repairs and maintenance, which may cause a short circuit accident or electric shock accident. There is one problem.

Further, in this conventional example, the holding piece 5 protruding from the upper surface of the insulating cylinder 1 and the lamp, particularly the wedge base valve, held by the holding piece 5 protrudes higher, so that the flattening as a whole is impossible. Therefore, there is a second problem that it cannot be used in a place where there is not enough vertical dimension, such as a ceiling light of an automobile.

Further, in the above-mentioned prior art, since the lamp or the like is supported only by the holding piece 5, and there is no other means for directly guarding the lamp or the fuse, there is no need to feed the lamp like the wedge base valve. In order to support and use an object with a large protruding tube from the base only with the holding pieces 5, 5, a large force is applied to the holding piece 5 which is a fulcrum on the principle of lever and the attachment becomes unstable, and the lamp is damaged by vibration or other disturbance. There is also a third problem that the fuse is easily removed.

In order to eliminate the above-mentioned problems, the present invention attaches the wedge base valve to the non-heat resistant member through the heat resistant holder without directivity, so that the heat resistant and insulating structure is inexpensive and reliable. In addition to ensuring the above, the flatness of the whole is measured, and the mounting of the holder including the connecting tool to the mounted member is automated.

[0007]

DISCLOSURE OF THE INVENTION The above-mentioned object of the present invention is to attach an insulating holder, to which a connecting tool is attached, to a member to be attached and to use the insulating holder, which is made of heat-resistant plastic and formed into a substantially flat rectangular tube shape. A tubular body, opposing pieces formed on both sides in the width direction of the insulating tubular body, projections projecting on the inner surface of the tubular body between these opposing pieces, and a pair of sandwiching pieces formed by forming an elastic conductive plate into a substantially U shape. And two connecting tools each integrally provided with a plug-in connecting piece in the base and mounting holes formed in the base of the sandwiching piece for these two connecting tools are insulated from each other through the protrusions between the facing pieces. A valve holder mounted in parallel along the length direction of the tubular body, an attachment hole slightly larger than the plane contour of the insulating tubular body, and upper and lower engaging hook pieces protruding near the edge of the attachment hole. And the mounted body having the It was achieved by the attached by locking hook piece in its attachment bore the biasing member.

[0008]

[Operation] The insulating cylinder is attached between the edge of the attachment hole of the attached body from one of the upper and lower engagement hook pieces of the plurality of engaging hook pieces protruding above and below the attachment hole edge of the attached body. When inserting, the locking hook piece spreads outwards against its elasticity, and then the locking hook piece is disengaged from the side of the insulating cylinder, so that the locking hook piece is restored by its elasticity. Returning to this, the valve holder can be easily attached to the body to be attached by the snap with the snap, using the engaging hook piece at the edge of the attachment hole.

Further, since a U-shaped holding piece is provided between the upper and lower facing surfaces of the substantially rectangular insulating cylinder along the length direction of the insulating cylinder, the upper and lower surfaces of the insulating cylinder are separated from each other. Has no protrusion, and the surroundings of the gripping piece are surrounded by an insulating cylinder that is an electrical protection member, so unnecessary outer conductors (drivers and other tools) for car repair etc. There is no contact with the conductive parts of the lamp, so there is no short circuit or electric shock.

Further, according to the present invention, since the holding piece and the lamp, particularly the wedge base bulb, held by the holding piece do not project on the upper and lower surfaces of the insulating cylinder, the flattening as a whole is possible. Further, in addition to the holding piece, the present invention has a cylinder facing surface that guards the power supply base of the lamp or fuse, so even if the bulb largely projects from the power supply base of the lamp, such as a wedge base valve. It can be used with stable and reliable support.

Further, in the above-mentioned mounted state, the vertical movement of the insulating cylinder with respect to the attached body is such that the opposite hook edges of the pair of locking hook pieces are in contact with the upper and lower surfaces of the attached body, respectively. Therefore, the horizontal movement of the insulating cylindrical body can be restricted by the periphery of the attachment hole of the attached body without any rattling.

EXAMPLES Examples will be described with reference to the drawings. First, the basic structure of the present invention is that a heat-resistant plastic such as 66 Nylon is used to form a mounting structure for a connecting tool by attaching an insulating holder to which the connecting tool is attached to a member to be mounted. Insulation cylinder molded into a flat rectangular tube shape like
As shown in FIG. 3, protrusions 4 and 4 are provided on the upper and lower facing surfaces 1a, 1a of the cylindrical body between the facing pieces 3 and 3 formed on both sides of the width direction of 1 and one facing surface 1a.

Further, an elastic conductive plate made of phosphor bronze or the like is molded into a substantially U-shape as shown in FIG. 1 to integrally form a pair of holding pieces 5, 5 and a base spectacle-shaped insertion connecting piece 6 is integrally formed. The two connecting tools 7, 7 provided for the purpose of being installed in the insulating substrate 1 as shown in FIG.
It is sandwiched as shown in FIG. That is, at this time, the pair of protrusions 4 and 4 are engaged with each other in the mounting holes 8 and 8 formed in the base of the holding pieces 5 and 5 while being depressed against the elasticity thereof. , 5 are elastically restored and the connecting tools 7, 7 are mounted between the base-facing surfaces 1a, 1a as shown in FIG. 3 to form a valve holder 9. It should be noted that, if the connecting tool 7 having two projecting ribs projecting as shown by the chain line in FIG. 1 is used, the gripping resilience can be enhanced and the heat dissipation can be improved.

Further, an attachment hole 10 slightly larger than the planar contour of the insulating cylinder 1 and a large hole 10a connected to the attachment hole 10a.
Locking hook pieces formed by projecting the valve holder 9 above and below the edge of the attachment hole on a mounted body 11 formed as shown in FIG.
2 and 2, the attachment member 10 is attached to the attachment body 11 through the attachment hole 10 as shown in FIG.

That is, when mounting the valve holder 9 in the mounting hole 10 of the mounted body 11, the insulating cylindrical body 1 is mounted in the mounting hole 10.
The slanting surface 2a of the locking hook pieces 2, 2 of the mounted body 11 is pushed by the moving force approaching 10 and the locking hook piece 2 bends outward against its elasticity, and the hook edge 2b is insulated. When it is disengaged from the side 3 of the cylinder 1, the locking hook piece 2 snaps back due to its elasticity, and the valve holder 9 is supported by supporting the upper and lower surfaces of the insulating cylinder 1 with the hook edges 2b by one-shot locking. It can be easily attached to the attached body 11 through the attachment hole 10.

If the insulating cylinder 1 is provided with the ventilation hole 1b as shown by the chain line in FIG. 1, the heat dissipation is further improved, and the upward or downward direction of each of the locking hook pieces 2 and 2 is improved. The slope 2a of either one can be omitted,
In addition, the protruding portion provided on the side 3 of the insulating cylinder 1 as shown in FIG.
The upper and lower edges of 3A may be supported by the locking hook pieces 2,2.

Next, an example of its use will be described. A well-known wedge base valve 12 as shown in FIG. 1 is placed in the valve holder 9 at the base thereof from the chain line state in FIG. 4 to the solid line in FIG.
At this time, first, the lead parts 12a, 12a of the valve 12 are used to spread the holding pieces 5, 5 of the connector 7 between the holding pieces 5, 5 against the elastic force of these pieces.
Insert the valve until the b hits the holder step edge 9a.
Can be inserted into the holder 9 as shown in the above figures.

Next, as shown in FIGS. 2 and 3, the bent base portion of the bus bar 13 arranged along the surface of the body 11 to be mounted, for example.
The wedge base valve 12 can be turned on by pressing 13a into the connecting piece 6 to energize it. A well-known flat fuse may be inserted instead 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. This device is designed to hold a U-shaped holding piece between the upper and lower facing pieces 3 and 3 of the substantially rectangular insulating cylinder 1.
Since 5 is installed inside along the length direction of the insulating cylinder 1, there is nothing protruding from the upper and lower surfaces of the insulating cylinder, and the surroundings of the holding piece 5 are electrical protection members. Since it is surrounded by 1, unnecessary outer conductors (drivers and other tools) do not inadvertently contact the gripping piece 5 or the conductive part of the lamp held by this when a car is repaired or inspected, resulting in a short circuit or electric shock. Since it does not occur, it has the first effect of being safe.

Further, according to the present invention, since the holding piece 5 and the lamp, particularly the wedge base bulb, held by the holding piece 5 do not project on the upper and lower surfaces of the insulating cylinder 1, the flattening as a whole is possible. It also has a second effect that it can be used in a place where there is not enough vertical dimension, such as a ceiling light of an automobile.

In addition to the holding piece 5, the present invention has a cylindrical body-opposing surface that guards the power supply base of the lamp or fuse, so that the bulb greatly protrudes from the power supply base of the lamp like a wedge base valve. Even if it is present, it can be supported and reinforced in a reliable and stable manner, and there are many effects such as being safe because the lamp and fuse will not come off due to external disturbance such as vibration.

According to the second aspect, it is possible to add the effect that the waist of the connecting tool 7, that is, the holding elastic force, can be strengthened and the heat radiation can be improved.
