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.
No. 47818 (No. 02-137873) and No. 01-93178 (No. 01-93178).
3-32389) microfilms are well known. In all of these conventional examples, a U-shaped holding connector is orthogonally fixed to a rectangular flat frame-shaped valve holder member, and the holder member is hooked to a mounted object such as an automobile ceiling material. It was attached using.

[0003]

The former of the above-mentioned conventional examples cannot attach the connector assembly 9 from below the attached body. Further, in the latter case, the connector assembly 9 cannot be attached from above the attached body. Therefore, in both conventional examples, the degree of freedom in the vertical direction of automatic feeding of parts such as the valve holder during automatic assembly and mounting is reduced by half, and the directional maintenance management of the parts feeder becomes complicated. There is a problem of.

In each of the prior arts, the U-shaped holding piece 5 is provided so as to be orthogonal to the plane of the flat frame-shaped insulating cylinder 1, so that the holding piece protruding from the upper surface of the insulating cylinder is provided. Since there is no electrical protection member around 5, therefore, unnecessary outer conductors (drivers and other tools) are unintentionally attached to the gripping piece 5 or the conductive part of the straight tube lamp held by this when the vehicle is repaired or inspected. There is a second problem that it is dangerous because it is likely to come into contact and cause a short circuit accident or an electric shock accident.

Further, in each 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 further protrudes higher,
Since it cannot be flattened as a whole, there is a third problem that it cannot be used in a place having a small vertical dimension such as a ceiling light of an automobile.

Further, in each of the prior arts, a 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. In order to support and use an object with a large bulb protruding from the base with only the holding pieces 5, 5, a large force is applied to the holding piece 5 which is a fulcrum due to the lever principle, and attachment becomes unstable, and the lamp is damaged by disturbance such as vibration. There is also a fourth problem that the fuse is easily removed.

In order to eliminate the above-mentioned problems, the present invention unidirectionally attaches the wedge base valve to the non-heat resistant member via the heat resistant holder, 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.

[0008]

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 cylindrical body, side pieces on both sides in the width direction of the insulating cylindrical body, projections protruding from the inner surface of the cylindrical body between these opposing pieces, and a pair of sandwiching pieces and side edges formed by forming an elastic conductive plate into a substantially U shape. And two connecting pieces each integrally provided with a plug-in connecting piece formed through a rising base portion, and the two side pieces via the protrusions with attachment holes formed in the base portion of the sandwiching piece of these two connecting pieces. A valve holder mounted in parallel along the length direction of the insulating cylinder, an attachment hole slightly larger than the plane contour of the insulating cylinder, and upper and lower engagements protruding near the edge of the attachment hole. A valve body having a hook piece, It was achieved by the attached by locking hook piece in said holder body to be attached within the attachment hole.

[0009]

[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.

In this mounting, since the engaging hook pieces are formed above and below the edge of the attachment hole of the body to be attached, the valve holder can be attached to the edge of the attachment hole of the body to be attached from either the upper or lower hook piece. Yes, the valve holder itself can be mounted from either the top or bottom, and there is no vertical direction of mounting.

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. No accidental contact with the conductive parts of the lamp, no short circuit accidents 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 by supporting and reinforcing it.

In the mounted state, the vertical movement of the insulating cylinder with respect to the body to be attached is such that the hook edges of the upper and lower engaging hook pieces respectively contact the upper and lower surfaces of the body to be attached. There is no rattling, and the horizontal movement of the insulating cylinder can be restricted by the periphery of the attachment hole of the attached body.

Further, an elastic conductive plate made of phosphor bronze or the like is molded into a substantially U shape as shown in FIG. 1, a pair of holding pieces 5, 5 are integrally formed, and a flat spectacle shape is formed through a rising base portion 6a of a side edge. Two connecting members 7, 7 integrally provided with the plug-in connecting piece 6 are sandwiched in the insulating base 1 as shown in FIGS. 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 plane 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 piece 3 of the tubular body 1, the locking hook piece 2 snaps back due to its elasticity, and the upper and lower surfaces of the insulating tubular body 1 are supported by the hook edges 2b by one-shot locking, and the valve holder 9 is fixed. It can be easily attached to the attached body 11 through the attachment hole 10.

If the insulating cylinder 1 is provided with the vent hole 1b as shown by the chain line in FIG. 1, the heat dissipation is further improved, and the upward or downward facing of each of the locking hook pieces 2 and 2 can be improved. The slope 2a of either one can be omitted,
In addition, the protruding portion provided on the side piece 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, 3 and 8, the bent end 13a of the bus bar 13 arranged along the surface of the mounted body 11 is inserted into the insertion connecting piece 6 to energize it. The wedge base valve 12 can be turned on. In addition,
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.

[0021]

Since the present invention is constructed as described above, it has the following effects. This device is to be mounted
11 of the mounting hole, the insulating tubular body 1 is removed from one of the upper and lower engaging hooks 2, 2 of the plurality of engaging hooks 2, 2 protruding from above and below the edge of the mounting body 11. When inserted between the edges of the fitting hole 10, the locking hook piece 2 spreads in the direction in which the distance between the opposing locking hook pieces widens against the elasticity thereof, and then the locking hook piece 2 is removed from the side of the cylinder. When released, the locking hook piece 2 returns to its original position due to its elasticity, and the valve holder 9 is attached to the body to be attached by snapping with one click.
It can be easily supported and mounted in the attachment hole 10 of 11 by the locking hook piece 2.

In this mounting, since the present invention forms the locking hook pieces 2 on the upper and lower sides of the attachment hole 10 of the mounted body 11, the valve holder 9 can be mounted on the mounted body 11 by either the upper or lower hook piece. Since the valve holder 9 itself is a flat cylindrical body, it can be mounted from either the upper or lower side of the mounting hole 10, and there is no vertical direction of mounting.
The first effect is that it can be implemented without considering the directionality of the parts feeding.

Further, the present invention is directed to an insulating cylinder having a substantially rectangular tube shape.
Insulate the U-shaped holding piece 5 between the upper and lower facing pieces 3 and 3 of 1
Since it was installed along the length direction of 1, there is nothing protruding from the upper and lower surfaces of the insulating cylinder, and since the holding piece 5 is surrounded by the insulating cylinder 1 which is an electrical protection member. In addition, since unnecessary outer conductors (drivers and other tools) do not come into contact with the holding piece 5 or the conductive part of the lamp held by this when carrying out car repairs or maintenance, a short circuit accident or electric shock does not occur, so it is safe. There is also a second effect that there is.

Further, according to the present invention, since the holding piece 5 and the lamp, especially 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. There is also a third 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 gripping piece 5, the present invention has a cylinder facing 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, that is, the holding elastic force of the connector 7 can be strengthened, and that the heat dissipation can be improved.
