Abstract

PURPOSE: To install a wedge base bulb or the like on a non-heat resistant member with excellent heat radiation by integrally and protrusively arranging a sandwiching support elastic piece above a cylinder body of a holder, and sandwiching and guarding the wedge base bulb and a base part of a flat fuse. CONSTITUTION: A locking projecting piece and a sandwiching support elastic piece 1A are formed on both left and right side pieces of an insulating cylinder body 1 composed of heat resistant plastic. Projections 4 are arranged on opposing pieces 3. When an outside surface of the projecting piece 2 is pressed in between the edge sides of an installing hole 10 in an installing object 11 by using its slant face 2a, the side edge mutually bends the thin opposing pieces 3 in the inner direction against its resiliency. Afterward, the projecting piece 2 slips out of the edge side of the installing hole 10, and the side edge is restored to the former state, and a bulb holder 9 can be easily installed on the installing object 11 by the installing hole 10 by one-shot locking with a snap. Therefore, a lamp and a fuse do not slip out by disturbance such as vibration.

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 connector through a heat-resistant cylindrical holder.

[0002]

2. Description of the Related Art Conventionally, as a mounting structure of this kind of connecting tool, there has been one disclosed in, for example, Japanese Utility Model Laid-Open No. 4-5082. In this conventional technique, a block to which a connecting tool is attached is attached to a member to be used, and an insulating base formed by an insulating material into a substantially rectangular parallelepiped frame shape and a side piece of the insulating base are projected. A plurality of locking hook pieces and a flange piece, and two pairs of facing pieces forming a pair of elongated side piece escape holes from the inner surface of the side piece on both sides in the longitudinal direction of the insulating base; A pair of projections provided on the opposite surfaces of the two sets of facing pieces, and two connecting tools integrally formed with a pair of holding pieces and a plug-in connecting piece formed by forming an elastic conductive plate into a substantially U shape, A connecting tool assembly in which these two connecting tools are respectively mounted between two pairs of opposing pieces through the pair of projections through mounting holes formed in the base of the holding piece, and the insulating base It consists of the mounted body with mounting holes that are slightly larger than the plane contour. The connector assembly between the locking hook piece and Tsubahen a mounting structure of a connector which is attached in the attachment hole in the mounting member.

[0003]

In this conventional example, since a U-shaped holding piece is provided so as to be orthogonal to the plane inside the flat frame-shaped insulating base, the conductive material protruding from the upper surface of the insulating base is provided. Since there is no electrical protection member around the gripping piece, an external conductor (driver or other tools) that is unnecessarily useless for car repair and inspection, etc. is a holding piece or a straight tube lamp or glass tube fuse held by the holding piece. There is a first problem that it is dangerous because it is likely to cause a short circuit accident or an electric shock accident by coming into contact with the conductive part of.

Further, in the above-mentioned prior art, since the base portion such as the lamp is supported only by the sandwiching piece and there is no other means for directly guarding the lamp or the fuse, unlike the wedge base valve, the lamp power feeding is performed. In order to support and use an object with a large bulb protruding from the base only by the holding piece at the base, a large external force is applied to the holding piece due to the principle of lever, resulting in unstable mounting, and lamp or fuse due to disturbance such as vibration. There is also a second problem that it easily comes off.

According to the present invention, in order to eliminate the above-mentioned problems, a wedge base valve or the like is attached to a non-heat-resistant member via a heat-resistant cylindrical holder with good heat dissipation, so that inexpensive and reliable heat resistance can be obtained. It is an object to secure an insulating structure, to reinforce a valve or a fuse, and to automate mounting of the holder, including a connecting tool, on a member to be mounted.

[0006]

DISCLOSURE OF THE INVENTION The above-mentioned object of the present invention is to mount an insulating holder, to which a connecting tool is attached, on a member to be mounted by molding it with heat-resistant plastic into a substantially rectangular tube shape and directing it upward. Insulating cylinders with oppositely projecting projectiles, a plurality of locking projections protruding above and below the side of the insulating cylinder, and opposing pieces formed on both sides of the insulating cylinder, A projection provided on the inner surface of the facing piece, and two connecting tools each having an elastic conductive plate formed in a substantially U-shape and provided with a pair of holding pieces and a lead-out member such as a plug-in connecting piece or a lead wire at the base, A valve holder in which these two connecting tools are mounted parallel to each other along the height direction of the insulating tubular body between the facing pieces via the protrusions through mounting holes formed in the base of the holding piece, and the insulating tubular body. And the mounted body with mounting holes slightly larger than the plane contour of Could be achieved by the attached at the attachment hole in the mounting member by the valve holder wherein the upper and lower retaining tongue pieces.

[0007]

When the inclined surface of one of the upper and lower locking projections of the plurality of locking projections projecting above and below the side of the insulating cylinder is press-fitted between the edges of the attachment holes of the mounted body. , The side edge is pushed inward against the elasticity by the slope or the external force, and then the locking projection is disengaged from the edge of the attachment hole, so that the side edge returns to its original position due to its elasticity or By removing the external force on the side and returning the side, the valve holder can be easily attached to the body to be attached through the attachment hole by snapping and snapping.

Further, since a U-shaped holding piece is provided between the upper and lower facing surfaces of the substantially rectangular insulating cylinder along the height direction of the insulating cylinder, the upper and lower surfaces of the insulating cylinder are separated from each other. There is nothing protruding except the top of the lamp or fuse, and since the surrounding of the holding piece is surrounded by an insulating cylinder that is an electrical protection member, it is unexpectedly unnecessary for a vehicle repair or maintenance inspection. Tools do not come into contact with the holding piece or the conductive part of the lamp held by the holding piece, and a short circuit accident does not occur.

Further, according to the present invention, since the flannel projecting piece for protecting the lamp or fuse base by sandwiching the base is provided on the upper part of the cylindrical body, the bulb is provided from the power supply base of the lamp like a wedge base valve. Even a large protruding object can be reliably and stably reinforced and supported. Then, in the above-mentioned mounted state, the vertical movement of the insulating base body with respect to the mounted body is such that the opposing edges of the locking projections are above the mounted body, respectively.
Since it abuts on both lower surfaces, there is no rattling, and the horizontal movement of the insulating substrate can be restricted by the peripheral edge of the attachment hole of the mounted body.
