Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a wedge base valve and a flat fuse attached to a mounted member together with a connecting tool via a heat resistant flat holder.

[0002]

[Prior art]

 As a small lamp using a wedge base bulb, for example, there is a conventional one described in Japanese Utility Model Publication No. 53-1825.

This conventional technique includes a housing, a lens positioned in the opening of the housing, a holder attached to the housing, and a wedge base valve supported by the holder, the holder being made of a conductive metal plate. The holder body is formed by curving into a shape, and a mounting piece is formed integrally with the holder body so as to extend in a direction opposite to the U-shape. The housing is provided with a fitting recess of the holder body. At the same time, a central piece and left and right side pieces are provided so as to face each other above and below the fitting recess, and the holder main body is fitted into the fitting recess formed in the housing to fit the U-shaped portion of the holder main body. An indoor small lamp for an automobile, characterized in that it is sandwiched between the central 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]

[Problems to be solved by the device]

 In the conventional technology described above, the wedge base valve 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 deformation and rattling, and this rattling, it is sufficient to mold the valve holder part with a large volume housing with heat resistant resin, but heat resistant resin is expensive and difficult to mold and costly. There is the first problem.

[0007] Furthermore, the above-mentioned valve holder and the connecting member surrounding member have a complicated structure and require post-processing such as caulking, and it has been extremely difficult to automatically assemble indoor lights by automatic wiring including automatic insertion of the connecting device. There were two problems.

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 at the same time, a connecting tool. The first purpose is to automate the mounting of the holder on the mounted member.

[0007]

[Means for Solving the Problems]

 The above-mentioned object of the present invention is to mount an elastic conductive plate in a substantially U shape, and to attach a pair of holding pieces and two connecting tools each provided with a lead wire at the base with mounting holes formed at the base of the holding pieces. A pair of protrusions formed on the upper and lower facing surfaces of the rectangular cylindrical frame-shaped insulating base body are mounted in parallel between the facing surfaces to form a valve holder, which is slightly smaller than the planar contour of the insulating base body. This can be achieved by attaching the engaging hook piece to the attached body having a large attachment hole in the attachment hole.

[0008]

[Action]

 When the outer surface of the locking hook piece of the insulating base body is press-fitted between the edges of the attachment hole of the mounted body, the side edge of the base body pushes inward against its elasticity, and then the locking hook piece attaches to the attachment hole. The side edge returns to its original position by being disengaged from the edge of the valve holder, and the valve holder can be easily attached to the body to be attached through the attachment hole by the snap and 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 facing 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 peripheral edge of the attachment hole of the mounted body. By providing a pair of clamping pieces and a differential lead wire in one connector, the wedge base valve It can be held and held tightly with a pair of holding pieces, and can be used by being electrically connected to other members 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 the conductive plate or the insulating plate.

[0011]

【Example】

 Examples will be described with reference to the drawings. First, the basic structure of this invention is to mount an insulating holder to which a connecting tool is attached to a member to be mounted to form a mounting structure of the connecting tool, and a heat resistant plastic such as 66 nylon is used as shown in FIG. As shown in FIG. 1, a pair of locking hook pieces 2, 2 are formed on the left and right sides 3, 3 of the insulating base body 1 formed in the flat rectangular tube frame shape by using a known three-way opening / closing mold or the like.

Then, as shown in FIG. 3, protrusions 4 and 4 are provided so as to face each other on the upper and lower facing surfaces 1a and 1a of the base between the both side pieces 3 and 3 of the insulating base 1.

Further, as shown in FIG. 1, an elastic conductive plate made of phosphor bronze or the like is formed into a substantially U shape to integrally form a pair of holding pieces 5, 5, and a lead wire 6 is attached to the base portion by a crimping connection portion 6a. Two connecting tools 7,7 provided by crimp connection are sandwiched in the insulating base 1 as shown in FIGS.

That is, at this time, the pair of protrusions 4 and 4 are inserted into the mounting holes 8 and 8 formed near the base of the holding pieces 5 and 5 while being slid against the elastic force. A valve holder 9 is constructed by elastically returning the holding pieces 5 and 5 and mounting the connecting tools 7 and 7 between the base body facing surfaces 1a and 1a as shown in FIG.

Note that, as the above-mentioned connecting tool 7, if two projecting ribs 7a, 7a are provided in a projecting manner as shown in FIG. 7, the gripping elasticity can be enhanced and the heat dissipation can be improved.

Further, an attachment hole 10 slightly larger than the planar contour of the insulating base 1 and a large hole 10a connected to the attachment hole are formed on the mounted body 11 formed as shown in FIG. The connector 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, if the escape holes 11a and 11a for the locking hook pieces 2 and 2 as shown by the chain line in FIG. 6 are formed in the attached body 11 near the locking hook pieces 2 and 2, it will be even easier. If the valve holder 9 can be attached to 11 and the ventilation hole 1b is formed in the insulating substrate 1 as shown by the chain line in FIG. 1, heat dissipation can be further improved.

Next, an example of its use will be described. The well-known wedge base valve 12 as shown in FIG. 1 is inserted into the valve holder 9 at the base thereof from the state shown by the chain line in FIG. 4 as shown by the solid line in FIG. 4 and as shown in FIG. 3 and FIG. By inserting the valve base 12b into the holder step edge 9a while pushing the lead pieces 12a, 12a of the connector 12 between the holding pieces 5, 5 of the connector 7 against the resilience of these pieces, the valve 12 is inserted. Can be inserted into the holder 9 as shown in the above figures.

Next, 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.

[0021]

[Effect of device]

 Since the present invention is configured 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 5,5 and two connecting tools 7,7 each having a lead wire 6 at the base are formed at the base of the holding pieces 5,5. A valve holder 9 is formed by mounting parallelly between the facing surfaces 1a, 1a via a pair of protrusions 4, 4 formed on the upper and lower facing surfaces of the rectangular cylindrical frame-shaped insulating substrate 1 with the mounting holes 8, 8. Then, the holder 9 is mounted in the mounting hole 10 by the locking hook pieces 2a, 2a on the mounted body 11 having the mounting hole 10 slightly larger than the planar contour of the insulating base 1. You can

Therefore, even if only the small-volume bulb 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 the fuse can be secured. There is a first effect that the cost can be significantly reduced as compared with the conventional technology in which the whole is molded with expensive heat-resistant resin, and it is economical.

Further, in particular, in the attachment structure of the connector of the present invention, when the outer surface of the locking hook piece 2 of the insulating base 1 is press-fitted between the edges of the attachment hole 10 of the attached body 11, the side edge is After pushing inwardly against the elasticity, the locking hook pieces 2 disengage from the edges of the attachment holes 10 and each side returns to its original position, and the valve holder 9 is locked by one click. The attachment hole 10 can be easily and automatically attached to the attachment body 11.

In this mounted state, the vertical movement of the insulating base body 1 with respect to the mounted body 11 causes the opposite hook edges of the pair of locking hook pieces 2 to contact the upper and lower surfaces of the mounted body 11, respectively. Since there is no rattling, the horizontal movement of the insulating base 1 can be restricted by the periphery of the attachment hole 10 of the mounted body 11, and the locking hook piece formed on the insulating base 1 forming the valve holder 9 2 is mechanically robust because it is integrally molded firmly without moving with respect to the base 1, and the insulating base does not move unintentionally after mounting on the mounted body, so stability in use is maintained for a long time There is a second effect that it can be done.

In the assembled structure of the connecting tools 7,7, the connecting tools 7,7 are surrounded by the insulating base body 1. Therefore, the two connecting tools 7,7 are connected to the conductive plate / insulator via the insulating base body 1. The third effect is that it can be mounted on any board with good compatibility.

In particular, in the present invention, when a large number of wedge base valves, flat fuses, etc. are intensively mounted in a narrow space, the insulating base body 1 to which two connecting tools have been attached is attached to the locking hook pieces 2, 2 of the same. Therefore, there is a fourth effect that it can be easily and orderly arranged and mounted in the attachment hole 10 of the mounted body 11.

Further, according to the present invention, the wedge base valve or the like can be used by holding it tightly with a pair of connecting pieces 5, 5, and also by directly connecting other members to the lead wire 6. This eliminates the need for caulking tools and the like for mounting and mounting in the field of use, which was necessary in the above-mentioned prior art, while on the other hand, automatic assembly can be carried out at the manufacturing site and the engine room of the automobile can be mounted. The fifth effect is that the connection work can be easily performed even in such a narrow space or a dark place.

According to the second aspect, it is possible to add the effect that the rigidity of the connector 7 can be strengthened and the heat dissipation can be improved.
