[Detailed description of the device]

[0001]

[Industrial applications]

 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]

[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 technique described above, the wedge base bulb portion is directly formed in a part of the interior light housing, and the connection tool is inserted to form the interior light. Therefore, the heat generated by the lighting of the bulb causes the bulb holder to generate heat. To prevent the rattling due to deformation and rattling, it is sufficient to mold the above valve holder part with a large volume housing with heat resistant resin, but heat resistant resin is expensive and difficult to mold and costly. The first problem is that

In addition, the above-mentioned valve holder and the connector surrounding member have a complicated structure and require post-processing such as caulking, and it is extremely difficult to automatically assemble an indoor light by automatic wiring including automatic insertion of the connector. There was a point.

In order to eliminate the above-mentioned problems, the present invention attaches a wedge base valve to a large non-heat-resistant member via a small, heat-resistant insulating base body which is vertically and horizontally symmetrical and is inexpensive and inexpensive. An object of the present invention is to secure a reliable heat-resistant structure, and to eliminate the mounting directionality of the holder, including the connecting tool, to the member to be mounted to facilitate automation of assembly.

[0007]

[Means for Solving the Problems]

 The above-mentioned object of the present invention is to provide an elastic conductive plate in a substantially U-shape, and a pair of holding pieces and two connecting tools each integrally provided with a connecting piece in the base portion, at the base portion of the holding piece. The valve holders are configured by mounting the formed mounting holes in parallel to each other through the pair of projections formed on the upper and lower facing surfaces of the rectangular cylindrical frame-shaped insulating base body to form a valve holder. This can be achieved by attaching to the body to be attached, which has an attachment hole slightly larger than the plane contour, by the engaging hook piece at the attachment hole.

[0008]

[Action]

 To attach the valve holder in the attachment hole of the body to be attached, the inclined surface of the locking hook piece of the body to be attached is pushed by the moving force that moves the insulating substrate close to the attachment hole, and the locking hook piece is attached. Bends outwards against its elasticity, and when the hook edge comes off the side of the insulating base, the locking hook snaps back with its elasticity, and by one-shot locking the upper and lower surfaces of the insulating base The valve holder can be easily attached to the body to be attached through the attachment hole by supporting the hook with the hook.

In this mounted state, the vertical movement of the insulating base body with respect to the attached body can be restricted because the hook edges of the pair of locking hooks are in contact with the upper and lower surfaces of the insulating base body, respectively. In addition, the horizontal movement of the insulating base can be restricted by the peripheral edge of the attachment hole of the mounted body, and by forming one pair of the sandwiching piece and the plug-in connecting piece having the plug-in connecting piece in one connecting tool, The wedge base valve can be clamped and used by holding it tightly with a pair of clamp pieces, and the tab terminal or bus bar can be directly inserted tightly into the plug-in connection piece for connection.

Since the connecting tool itself 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, and the connecting base is connected to the insulating base during mounting. There is no vertical or horizontal insertion direction with the tool.

【Example】

 Examples will be described with reference to the drawings. First, the basic structure of the present invention is to mount a heat-resistant plastic such as 66 Nylon in FIG. 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 insulating base 1 between both sides 3 and 3 of the insulating base 1 formed in the shape of a flat rectangular tube.

Further, as shown in FIG. 1, an elastic conductive plate made of phosphor bronze or the like is molded into a substantially U shape, and a pair of holding pieces 5 and 5 and a pair of eyeglass-like plug-in connecting pieces 6 are integrally provided on the base. Two connectors 7,7 are sandwiched in the insulating base 1 as shown in FIGS. 3 and 5. That is, at this time, the pair of protrusions 4 and 4 are inserted into the mounting holes 8 and 8 formed in the base of the holding pieces 5 and 5 while the holding pieces 5 and 5 are compressed against the elastic force. The valve holder 9 is constructed by mounting 7, 7 between the base facing surfaces 1a, 1a as shown in FIG. If the connecting tool 7 has two projecting ribs 7a, 7a as shown by the chain line in FIG. 1, 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 base body 1 and a large hole 10a connected to the attachment hole are formed on the mounted body 11 as shown in FIG. According to the present invention, the da 9 is attached to the mounted body 11 at the attachment hole 10 as shown in FIGS. 5 and 6 by the locking hooks 2, 2 protruding above and below the edge of the attachment hole. It constitutes the mounting structure of the connector.

That is, when mounting the valve holder 9 in the mounting hole 10 of the mounted body 11, the locking hook of the mounted body 11 is moved by the moving force that brings the insulating base body 1 closer to the mounting hole 10. When the beveled surface 2a of 2, 2 is pushed, the locking hook piece 2 bends outwards against its resilience, and when the hook edge 2b is disengaged from the side 3 of the insulating base 1, the locking hook piece 2 With its elasticity, it snaps back to its original position, and the upper and lower surfaces of the insulating base 1 are supported by the hooks 2b by one-shot locking, so that the valve holder 9 can be easily attached to the body 11 to be attached through its attachment hole 10.

If the ventilation hole 1b is provided through the insulating substrate 1 as shown by the chain line in FIG. 1, the heat release is further improved, and either the upward facing or downward facing of each of the locking hook pieces 2 and 2 can be improved. One of the slopes 2a can be omitted, and the upper and lower edges of the protrusion 3A projecting on the side 3 of the insulating substrate 1 as shown in FIG. Good.

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 bus bars 13 and 13 arranged along the surface of the mounted body 11 are bent portions 13a and 13a, and the connecting portions 6 and 6 of the connecting tool 7 are inserted. The wedge base valve 12 can be turned on by plugging it in and energizing it. 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.

[0018]

[Effect of device]

 Since the present invention is configured as described above, it has the following effects. An elastic conductive plate is molded into a substantially U shape, and a pair of holding pieces 5,5 and two connecting pieces 7,7 integrally provided with a plug-in connecting piece 6 at the base are formed at the base of the holding pieces 5,5. The valve holder 9 is formed by mounting the parallel holes between the facing surfaces 1a, 1a through the paired projections 4, 4 formed on the upper and lower facing surfaces of the rectangular cylindrical frame-shaped insulating base body 1 by the mounting holes 8, 8. Then, the holder 9 is attached to the attached body 11 having the attachment hole 10 slightly larger than the planar contour of the insulating base body 1 by the engaging hook pieces 2 and 2 at the attachment hole 10. You can

Therefore, even if only the small-volume valve holder 9 is made of expensive heat-resistant resin, the heat resistance requirement around the lamp and the fuse can be secured, so that a significant cost reduction can be realized and it is economical. There is a first effect that.

Further, in particular, since the insulating base 1 and the connector 7 in the mounting structure of the connector of the present invention can have symmetrical shapes in the vertical and horizontal directions, respectively, when mounting and mounting these respective members, There is a second effect that the assembly can be performed without considering the up, down, left and right insertion directionality, and thus automation of the assembly can be promoted.

Further, when the insulating base 1 is mounted on the body 11 to be mounted, the vertical movement of the insulating base 1 relative to the body 11 to be mounted is such that the opposite hook edges of the plurality of locking hook pieces 2 are the insulating base 1. Since it is in contact with both the upper and lower sides, it can be regulated without rattling, and the horizontal movement of the insulating substrate 1 can be regulated by the periphery of the attachment hole 10 of the mounted body 11. It is mechanically robust because it is firmly formed integrally with the body 11, and since the insulating base body does not move unintentionally after mounting the insulating base body, it is said that stability during use can be maintained for a long period of time. There is also the effect of.

Further, in the assembled structure of the connecting tools 7,7, since the connecting tools 7,7 are surrounded by the insulating base body 1, the two connecting tools 7,7 are connected to each other through the insulating base body 1 to form a conductive plate / insulator. The fourth effect is that it can be mounted on any board with good compatibility.

Further, since the insulating base 1 is relatively small and the amount of resin used is small, even if it is molded with a high-priced heat-resistant plastic, it is economically viable and a relatively large amount of resin is used. Since it is not necessary to use particularly expensive heat-resistant plastic for the mounting insulating plate, there is also a fifth effect that the cost is reduced as a whole.

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 are attached is attached to the attachment hook 11 of the mounted body 11. Since the pieces 2 and 2 can be mounted in the attachment holes 10 of the mounted body 11, there is a sixth effect that the arrangement and mounting can be performed very easily and in an orderly manner.

Further, in the present invention, since the pair of connecting pieces 5, 5 and the plug-in connecting piece 6 having the plug-in connecting portion are integrally formed in one connecting tool 7, space saving, resource saving and cost reduction are achieved. In addition, the wedge base valve etc. can be held tightly by a pair of connecting pieces 5,5 and can be used for sandwiching, and the tab terminal or the bus bar can be directly inserted into the inserting connecting piece 6 for use. Therefore, the caulking tools and the like required in the above-mentioned prior art are not required, and therefore automatic assembly can be performed, and even in a narrow place or a dark place such as an automobile engine room, it can be easily performed. There is also a seventh effect that connection work can be performed.

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 dissipation is improved.
