[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 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 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 a mounting hole in which an elastic conductive plate is formed into a substantially U shape, and a pair of holding pieces and two connecting tools each having a lead wire at the base are formed at the base of the holding piece. 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 object to be attached, which has a large attachment hole, to the inside of the attachment hole by means of its locking hook piece.

[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 with respect to the mounted 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, respectively, without rattling. Further, the horizontal movement of the insulating base can be restricted by the periphery of the attachment hole of the mounted body, and by providing one pair of holding pieces and lead wires in one connecting tool, the wedge base valve can be controlled by one pair of holding pieces. It can be held tightly and pinched, and it can be used by being electrically connected to other members by means of lead wires. Since the connector itself is surrounded by the insulating base, it is possible to mount the two connecting tools with good compatibility regardless of the conductive plate or the insulating plate through this base, and moreover, the insulating base and the connecting tool at the time of mounting. There is no vertical or horizontal insertion direction.

[0009]

【Example】

 Examples will be described with reference to the drawings. First, the basic structure of the present invention is to attach an insulating holder to which a connecting tool is attached to a member to be attached 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. 3, protrusions 4 and 4 are provided so as to face each other on the upper and lower facing surfaces 1a and 1a between the left and right sides 3 and 3 of the insulating base 1 formed in the flat rectangular tubular frame shape.

Further, as shown in FIG. 1, an elastic conductive plate made of phosphor bronze or the like is molded 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 projections 4, 4 are engaged in the mounting holes 8, 8 formed near the base of the holding pieces 5, 5 while being slid against the elastic force. A valve holder 9 is constructed by elastically returning the holding pieces 5, 5 and mounting the connecting tools 7, 7 between the base body facing surfaces 1a, 1a as shown in FIG.

Note that, as the above-mentioned connecting tool 7, by using two projecting ribs 7a, 7a as shown in FIG. 7, 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. As shown in FIG. 6 and each of the drawings, the datum 9 is attached to the mounted body 11 by means of the locking hook pieces 2, 2 protruding from above and below the edge of the attaching hole. Consists of a connector mounting structure.

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 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.

[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 attached in the attachment hole 10 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. You can

Therefore, even if only the small-volume valve 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 fuse can be secured. The first effect is 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, since the insulating base 1 and the connector 7 in the mounting structure of the connector of the present invention can be made symmetrical in the vertical and horizontal shapes 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 body 1 is mounted on the mounted body 11, the vertical movement of the insulating base body 1 with respect to the mounted body 11 is such that the opposing hook edges of the plurality of locking hook pieces 2 are the insulating base body 1 respectively. 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 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 1, the two connecting tools 7,7 are connected to the conductive plate / insulating via the insulating base 1. The fourth 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. Thus, there is a fifth effect that it can be easily and neatly 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 while being tightly held by the pair of connecting pieces 5 and 5 and can be used by directly connecting the lead wire 6 to another member. This eliminates the need for caulking tools and the like for mounting and mounting at the site of use, which was necessary in the prior art described above, while automatic assembly can be carried out at the manufacturing site, and it can be used in the engine room of automobiles. The sixth effect is that the connection work can be easily performed even in a narrow place or a dark place.

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.
