[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.

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 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 provide an elastic conductive plate having a substantially U-shape and two connecting members each having a pair of holding pieces, a locking bullet piece and a lead wire at the base, and these two connecting tools. Valve holders, which are attached to the inner surface of the opposing piece of the insulating base body between the projecting surfaces and the inner surface step edge via the pair of locking edges in the hole of the insulating base body with the locking bullet pieces, and It is composed of an attached body in which an attachment hole slightly larger than the planar contour of the insulating base is formed, and it can be achieved by attaching the valve holder to the attached body with the engaging hook piece 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 attached body, the side edge pushes in the direction of narrowing the side relief hole against its elasticity and then locks. When the hook piece is disengaged from the edge of the attachment hole, the side piece returns to its original position and snaps with one click, so that the valve holder can be easily attached to the attached body in the attachment hole.

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 periphery of the attachment hole of the mounted body. By providing one pair of clamp pieces and lead wires in one connector, wedge base valve It can be used by holding it tightly with a pair of holding pieces, and can be used by being electrically connected to another member 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 of the insulating base body 1 formed in the flat rectangular tubular frame shape by using a known three-way opening / closing die or the like.

Then, on both sides in the width direction of the insulating substrate 1, elongated side relief holes 3a, 3a are respectively formed from the inner surface of the side side so as to be formed as shown in FIG. 1 and FIG. On each inner surface of each piece, engaging edges 4,4 formed as shown in FIG. 4 and projecting surfaces 1a, 1a provided so as to face each other on the upper and lower sides of the base body are provided as shown in the respective figures.

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 sandwiching pieces 5, 5 and locking bullet pieces 8, 8 and lead at the base. Two connecting tools 7,7 provided by crimp-connecting the wire 6 at the crimp-connecting portion 6a are sandwiched in the insulating substrate 1 as shown in FIGS. That is, at this time, the locking bullet pieces 8 and 8 are inserted between the facing piece 3 and the projecting surface 1a while shrinking against the elastic force, and the locking bullet pieces 8 and 8 are attached to the locking edges 4 and 4. , 8 are engaged, and then the elastic pieces 8,8 are elastically returned to engage with the engaging edges 4,4 so that the connecting tools 7,7 are inserted between the base body facing piece 3 and the projecting surface 1a, respectively. Attach the valve holder as shown in 5 to configure the valve holder 9. The insertion amount of the above-mentioned connecting tool 7 can be limited by the tip contacting the front step edge 1b of the base body 1, and as the connecting tool 7, as shown in FIG. 1, punching ribs 5a, 5a are provided on the holding pieces 5,5. By using a projecting one, it is possible to enhance the gripping elasticity and improve heat dissipation.

Further, an attachment hole 10 slightly larger than the plane contour of the insulating substrate 1 and a large hole 10a connected to the attachment hole are formed on the mounted body 11 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, 11a for the locking hook pieces 2, 2 as shown by the chain line in FIG. 6 are formed in the mounted body 11 in the vicinity of the locking hook pieces 2, 2, it is even easier to mount. If the valve holder 9 can be attached to the body 11 and the ventilation hole 1c is formed in the insulating substrate 1 as shown by the chain line in FIG. 6, heat dissipation is 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. Insert the valve 12 into the holder 9 as shown in the above figures by inserting the lead pieces 12a and 12a of 12 between the holding pieces 5 and 5 of the connector 7 while pushing them apart against the elasticity of these pieces. Therefore, the lead portions 12a, 12a of the valve 12 can be electrically connected by sandwiching the holding pieces 5, 5 tightly.

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 molded into a substantially U-shape, and a pair of holding pieces 5,5, locking bullet pieces 8,8 and two connecting tools 7,7 each having a lead wire 6 at the base, and these two connecting pieces The tool 7 and 7 are engaged with the engaging bullets 8 and 8 through the pair of engaging edges 4 and 4 in the hole of the insulating base 1 and the inner surface and the projecting surface of the facing pieces 3 and 3 of the insulating base 1. It comprises a valve holder 9 mounted between 1a and in contact with the inner step edge 1b, and a mounted body 11 having an attachment hole 10 slightly larger than the planar contour of the insulating base body 1. It is possible to attach to the attached body 11 through the attachment hole 10 by the locking hook pieces 2, 2.

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, 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 in the direction in which the side relief holes 3a, 3a narrow against the elasticity, the locking hook 2 disengages from the edge of the attachment hole 10 and the side piece returns to its original position and snaps with one snap. Thus, the valve holder 9 can be easily and automatically mounted in the attachment hole 10 of the mounted 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 firmly molded integrally with the base 1 without moving, and since the insulating base does not move unintentionally after mounting on the mounted body, stability during use is improved. There is also a second effect that it can be maintained for a long period of time.

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 third effect is that it can be mounted on any board with good compatibility.

In particular, according to the present invention, when a large number of wedge base valves, flat fuses, etc. are intensively mounted in a narrow space, the valve holder 9 to which the two connecting tools are attached is attached to the locking hook pieces 2,2. It can be easily and neatly arranged and mounted in the attachment hole 10 of the mounted body 11, and since there are two side piece escape holes 3a, it is excellent in the heat dissipation effect of the opposing pieces 3,3 and the connecting tools 7,7 by convection. There is a fourth effect that high-density mounting is possible.

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 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 waist of the holding pieces 5, 5 of the connection tool 7 can be strengthened and that the heat radiation is improved.
