[Conventional technology]

As a mounting structure for this type of connector, for example, there has been one described in Japanese Patent Application Laid-Open No. 4-5082. In this conventional technique, a block to which a connector is attached is attached to a member to be attached and used, and the insulating base is formed into a substantially rectangular parallelepiped shape with an insulating material and is projected onto a side piece of the insulating base. A plurality of locking hook pieces and brim pieces, and two pairs of opposing pieces formed by having elongated side piece relief holes from the inner surface of the side pieces on both sides in the length direction of the insulating substrate, and these. A pair of protrusions protruding from the facing surfaces of the two sets of facing pieces, and two connecting tools in which an elastic conductive plate is formed into an almost U shape and a pair of holding pieces and a plug-in connecting piece are integrally provided. The connector assembly in which these two connectors are mounted between the two pairs of opposing pieces via the paired protrusions at the mounting holes formed at the base of the holding piece, and the insulating substrate. It is composed of an attached body having a mounting hole slightly larger than a plane contour, and the connector assembly is attached to the mounted body with the locking hook piece and the brim piece at the mounting hole. It is a mounting component of.

[Problems to be Solved by the Invention]

In this conventional example, since the U-shaped holding piece is projected inside the flat frame-shaped insulating base at right angles to the plane thereof, the conductive holding piece protruding from the upper surface of the insulating base is electrically surrounded. There is no protective member at all, so an external conductor (driver and other tools) that is unexpectedly useless for car repairs and inspections comes into contact with the holding piece and the conductive part of the straight tube lamp or glass tube fuse held by it, causing a short-circuit accident. There is the first problem that it is dangerous because it is prone to electric shock accidents.

【0004】

Further, in the above-mentioned prior art, the base such as the lamp is supported only by the holding piece, and there is no other one that directly guards the lamp or the fuse. To support and use a bulb with a large protrusion only by the holding piece at the base, as a result of applying a large external force to the holding piece by the principle of technology, attachment becomes unstable, and lamps and fuses can easily be used due to disturbances such as vibration. There is also a second problem, such as coming off.

【0005】

In 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 tubular holder with good heat dissipation, thereby achieving an inexpensive and reliable heat-resistant and insulating structure. The purpose is to secure and to reinforce valves and fuses, and to automate the mounting of the holder on the mounted member including the fittings.

[Means for solving problems]

The object of the present invention described above is that when the insulating holder to which the connector is attached is attached to the member to be attached, the insulating holder is formed into a substantially square cylinder shape with heat-resistant plastic, and the support bullet pieces are projected upward. An insulating cylinder, a plurality of locking protrusions protruding above and below the side sides of the insulating cylinder, facing pieces formed on both sides of the insulating cylinder, and protruding on the inner surface of these facing pieces. Two connecting tools, each of which is formed by molding a protrusion and an elastic conductive plate into an almost U shape and having a pair of holding pieces and a lead-out member such as a connecting piece and a lead wire at the base, and holding these two connecting tools. A valve holder formed in the base of one piece and mounted in parallel between the facing pieces via the protrusion along the height direction of the insulating cylinder, and a handle slightly larger than the plane contour of the insulating cylinder. This was achieved by attaching the valve holder to the attached body through the attachment holes by the upper and lower locking projections, which consisted of an attached body having a hole formed therein.

【0007】

[Action]

When the slope of one of the upper and lower locking protrusions of the plurality of locking protrusions projecting above and below the side of the insulating cylinder is press-fitted between the edges of the attachment holes of the attached body, the side The side is pushed inward against the elasticity by the slope or the external force, and then the locking projectile is disengaged from the edge of the attachment hole, so that the side is restored by the elasticity or the side external force. The side side is returned to its original position except for, and the valve holder can be easily attached to the attached body through its attachment hole by snapping and locking.

【0008】

In addition, since a U-shaped holding piece is installed between the upper and lower facing surfaces of the almost square tubular insulating cylinder along the height direction of the insulating cylinder, lamps and fuses are installed from the upper and lower surfaces of the insulating cylinder. There is nothing protruding other than the upper part of the lamp, and since the holding piece is surrounded by an insulating cylinder that is an electrical protection member, it is unexpectedly useless for car repairs, maintenance and inspections, etc. External conductors (drivers and other tools) Does 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.

【0009】

Further, in the present invention, since the support bullet piece that holds and guards the base of the lamp or fuse is projected from the upper part of the cylinder, the tube protrudes greatly from the power feeding base of the lamp like a wedge base bulb. Even if it is present, it can be reinforced and used reliably and stably. Then, in the above-mentioned mounting state, the vertical movement of the insulating substrate with respect to the mounted body is insulated without rattling because the facing edges of the locking projections are in contact with both the upper and lower surfaces of the mounted body, respectively. The horizontal movement of the substrate can be regulated at the periphery of the attachment hole of the attached body.

[Example]

Examples will be described with reference to the drawings. First, the basic configuration of the present invention is to use a heat-resistant plastic such as 66 nylon when the insulating holder to which the connector is attached is attached to the member to be attached to form the attachment structure of the connector. Locking projectiles 2 and 2 on both left and right sides of the insulating cylinder 1 formed into a square cylinder as shown in the figure, and the supporting bullet pieces 1A and 1A protruding upward are shown by a well-known three-way opening and closing mold, respectively. Mold as in 1.

【0011】

Of the upper and lower locking projectiles 2, 2, for example, a slope 2a is formed on the upper part of the upper two locking projectiles 2 as shown in FIG. 1, but this slope is the lower projecting piece. It may also be formed at the bottom of 2. Then, the protrusions 4 are projected as shown in FIGS. 3 and 4 on both or one of the cylinder facing surfaces between the facing pieces 3 and 3 formed on both sides of the insulating cylinder 1 in the width direction.

【0012】

In addition, as shown in Fig. 1, an elastic conductive plate made of phosphor bronze or the like is molded into an almost U shape, and two holding pieces 5 and 5 and a pair of eyeglass-shaped insertion connecting pieces 6 are integrally provided at the base. The fittings 7 and 7 are attached to the insulating cylinder 1 as shown in FIGS. 3 to 5. That is, at this time, while the upper part of the holding pieces 5 and 5 is deflated against the elasticity, the elasticity after engaging the paired protrusions 4 and 4 in the mounting holes 8 and 8 formed at the base thereof. After returning, these connectors 7 and 7 are mounted between the facing surfaces of the substrates as shown in FIG. 4, respectively, to form the valve holder 9.

【0013】

Further, the valve holder 9 is mounted on the mounted body 11 in which the mounting hole 10 slightly larger than the planar contour of the insulating cylinder 1 is formed as shown in FIG. 1, and the locking projection pieces 2 and 2 are mounted on the slope thereof. The attachment structure according to the present invention can be configured by attaching the attachment hole 10 to the attached body 11 as shown in each of FIGS. 2 to 7 by using 2a or the like.

【0014】

That is, the outer surface of any of the upper and lower locking projections 2 of the plurality of locking projections 2 and 2 projecting above and below the side of the insulating cylinder 1 is to be attached to the body 11 by using the slope 2a. When press-fitting between the edges of the attachment holes 10 of the above, the side surfaces are pushed inward against each other against the elasticity, and then the locking projections 2 are disengaged from the edges of the attachment holes 10. The side side returns to its original position due to its elasticity, and the valve holder 9 can be easily attached to the attached body 11 through the attachment hole 10 by snapping and locking.

【0015】

The portion indicated by reference numeral 3a in FIGS. 4, 5 and 7 is a niger groove for facilitating the bending of the opposing pieces 3 and 3, but when the opposing pieces 3 and 3 are thin, the niger groove 3a is unnecessary. Also, instead of the plug-in connection piece 6 integrally formed at the base of the holding pieces 5 and 5, the connector 7 is connected to another place by a lead wire or a lead wire 6a such as a bus bar as shown in FIGS. 8 and 9. You may do so.

【0016】

Next, an example of its use will be described. A well-known wedge base valve 12 having an energizing lead portion 12a as shown in FIG. 1 is inserted into the valve holder 9 at its base 12b from the chain line state of FIG. 4 as shown in the solid line of FIG. 4 and as shown in FIGS. 3 and 5. However, at this time, first, the lead portions 12a and 12a of the valve 12 push the holding pieces 5 and 5 of the connector 7 between the holding pieces 5 and 5 against the elasticity of each piece until the valve base 12b hits the holder step edge 9a. By inserting the valve 12, the valve 12 can be inserted into the holder 9 as shown in each of the above figures.

【0017】

Next, as shown in FIGS. 1 and 7, the bus bars 13 and 13 arranged along the surface of the attached body 11 are attached to the insertion connecting portions 6 and 6 of the connecting tool 7 at the bent portions 13a and 13a. The wedge base bulb 12 can be turned on by inserting a hook and energizing as described above, or by energizing with the lead-out member 6a (FIGS. 8 and 9 above). A well-known flat fuse may be inserted instead of the wedge base valve 12, but at this time, the valve holder 9 shall be read as a fuse holder, and the slope 2a of the locking projection 2 may be omitted. If this is omitted, the valve holder 9 can be attached to the attached body 11 through the attachment hole 10 while the side side of the cylinder is bent and dented by an external force.

【0018】

[Effect of the invention]

Since the present invention is configured as described above, the effects described below are obtained. In the present invention, since the support bullet pieces 1A and 1A that pinch and guard the base of the wedge base valve and the flat fuse are integrally projected on the upper part of the cylinder, the tube is formed from the power feeding base of the lamp like the wedge base valve. It has the first effect that it is safe because the lamp and fuse do not come off due to disturbance such as vibration, because it can be supported and used by holding and reinforcing it reliably and stably even if it protrudes greatly.

【0019】

In particular, in the present invention, the slope 2a is used for the outer surface of the locking protrusion 2 having a slope on either the upper or lower side of the plurality of locking protrusions 2 and 2 protruding above and below the side of the insulating cylinder 1. When press-fitting is performed between the edges of the attachment holes 10 of the attached body 11 by such means, the side surfaces are pushed inward against each other against the elasticity, and then the locking projections 2 are placed on the edges of the attachment holes 10. By detaching from, the side side returns to its original position with its elasticity, and the valve holder 9 can be easily and automatically attached to the attached body 11 through the attachment hole 10 by snapping and locking, and in the used state, the valve holder 9 can be easily and automatically attached. The second and third effects of preventing thermal deformation of the valve holder 9 and further safety because it exhibits an air-cooling effect by the radiator action of the support pieces 1A and 1A and radiates heat well from the heat intrusion from the valve and fuse. There is also.

【0020】

Further, in the present invention, a U-shaped holding piece 5 is installed between the left and right opposing pieces 3 and 3 of the substantially square tubular insulating cylinder 1 along the height direction of the insulating cylinder 1 to form a conductor. Since the holding piece 5 is surrounded by an insulating cylinder 1 which is an electrical protection member, an external conductor (driver and other tools) suddenly holds the holding piece 5 and a lamp held by the outer conductor during car repair or maintenance inspection. There is also a fourth effect that it is safer because it does not come into contact with the conductive part of the device and does not cause a short circuit accident or an electric shock accident.
