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 member to be attached together with a connecting tool through a flat holder.

[0002]

[Prior art]

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

This conventional technique includes a lens located in an opening of a housing, a holder attached to the housing, and a wedge base valve supported by the holder, and the holder has a U-shaped conductive metal plate. The holder main body is formed by curving, and the mounting piece is integrally formed with the main body so as to extend in a direction opposite to the U-shape. The housing is formed with a fitting recess of the holder main body. A center piece and left and right side pieces are provided on the upper and lower sides of the fitting concave portion so as to face each other with a space therebetween, and the holder main body is fitted into the fitting concave portion formed in the housing so that the U-shaped portion of the holder main body is An indoor small lamp for an automobile, characterized in that it is sandwiched between a central piece and both side pieces, and in this state, the mounting 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 above-mentioned conventional technique, the holder portion of the wedge base valve is formed directly on the side of the hole of the interior lamp housing, and the connector is directly attached and attached to the housing substrate to form the interior lamp. If you use a valve of about 5 W or more, the heat generated when the bulb lights up causes heat to come into contact with the valve holder and its surroundings, causing the substrate to deform thermally and rattling, resulting in a large contact resistance at the rivet. The first problem is that the rattling increases at an accelerating rate and eventually becomes unusable.

In addition, since the valve holder and the member around the connecting tool have a complicated structure, a post-processing connection by manual work such as caulking with a rivet is required, and furthermore, the automatic connection of the connecting tool is first performed in the room by automatic wiring. The second serious problem was that automatic assembly of the lamp was extremely difficult.

In order to eliminate the above-mentioned problems, the present invention provides a relatively small holder for holding a wedge base valve or the like integrally with a relatively large plastic substrate so as to be inexpensive and inexpensive. The objective is to secure a reliable valve and fuse holding structure, and to automate the mounting of the connection tool to other circuits, starting with the attachment of the connection tool to the holder.

[0007]

[Means for Solving the Problems]

 The above-mentioned object of the present invention is to use an insulating holder having a connecting tool integrally formed on a member to be mounted, in which a cylindrical box made of plastic is integrally erected and the insulating box A pair of projections formed on the inner surface of the frame facing each other and an elastic conductive plate formed into a substantially U shape, and two connecting members each having a pair of holding pieces and a narrow conductive plate continuous to the base thereof, These holders are provided with mounting holes formed in the vicinity of the base of the sandwiching piece for these two connecting tools, and holders mounted in parallel between the facing inner surfaces via the pair of projections, respectively. This can be achieved by disposing the extending end portion of the plate in the connector recess formed in the base frame so as to project therefrom.

[0008]

[Action]

 A relatively small insulating frame is integrally projected on a relatively large area plastic box frame, and a pair of connecting pieces mounted in parallel by concave and convex engagement inside this insulating frame is used to connect the wedge base lamp and flat small fuse. You can hold it tightly and use it for connection.

Therefore, a space around the lamp and the fuse is vacant, and the heat generated by the lamp and the like is radiated well by convection and radiation, and the heat of the connector is well radiated by the narrow conductive plate connected to it. The local temperature rise of the frame and box is minimal.

【Example】

 Examples will be described with reference to the drawings. First, the basic configuration of the present invention is to attach an insulating holder to which a connecting tool is attached to a member to be attached to construct a mounting structure of the connecting tool, which is shown in FIG. As shown in Fig. 3, the projections 4 and 4 are provided so as to face each other on the opposing inner surfaces 1a and 1a of the insulating frame 1 projectingly formed into a rectangular tubular frame shape as shown in Fig. 2 at the bottom of such a plastic box frame 2. 2, an elastic conductive plate made of phosphor bronze, etc. is formed into a substantially U shape as shown in FIG. 2, and has a pair of holding pieces 5,5, and the base portions 5a of these holding pieces 5,5 are shown in FIG. As shown in FIGS. 1 and 3 to 6, two connecting members 7, 7 each having a small-width conductive plate 6 such as a bus bar integrally projecting as shown in FIG. 7 are sandwiched in the insulating frame 1 as shown in FIGS.

Note that the narrow conductive plate 6 may be bent and formed horizontally with respect to the holding piece base 5a as shown in FIG. 8 or may be led out by being overlapped on the base 5a as shown in FIG. Alternatively, they may be fixed by pressure to the base 5a or fixed by soldering.

Then, at the time of the above-mentioned insertion, while inserting the holding pieces 5, 5 into the space between the opposing inner surfaces 1a, 1a of the insulating frame 1 while shrinking the holding pieces 5 and 5 against the elasticity, the holding pieces 5 are placed near the base 5a. The pair of projections 4 and 4 are engaged in the formed mounting holes 8 and 8 by the elastic return of the snap and the connecting piece 5, and the connecting tools 7 and 7 are inserted on both sides between the insulating frame facing inner surfaces 1a and 1a. 1 and 3, respectively, and a narrow conductive plate 6 is inserted into the back surface recessed groove 2a of the box frame 2 to form the valve holder 9 as a whole.

It should be noted that if the connecting tool 7 having two projecting ribs 7a, 7a as shown in FIG. 1 is used, the gripping resilience can be enhanced and the heat dissipation can be improved.

The extending end 6a of the small-width conductive plate 6 in the holder 9 is projectingly arranged in the connector recess 2A formed in the base frame 2 to construct the device of the present invention.

Next, an example of its use will be described. The well-known wedge base valve 12 as shown in FIGS. 1 and 2 is inserted into the valve holder 9 at its connecting base portion as shown in FIGS. 3 to 6. At this time, first, the lead portion 12a of the valve 12, Insert the valve base 12b into the holder 9 by inserting the valve base 12b into the holder 9 while pushing the holding pieces 5 and 5 of the connector 7 against each other with the force of 12a while pushing them apart. The wedge base valve 12 can be turned on by inserting electricity as shown in the figure and passing electricity through a well-known female connector (plug-in jack) connected to the ends 6a of the narrow conductive plates 6,6.

A well-known flat fuse may be inserted and used in place of the wedge base valve 12, but at this time, the valve holder 9 is read as a fuse holder.

[0017]

[Effect of device]

 Since the present invention is configured as described above, it has the following effects. A relatively small insulating frame 1 is integrally projected on a relatively large-area plastic box frame 2, and a pair of connecting pieces mounted in parallel in this insulating frame 1 by concave and convex engagement is used for wedge base lamps and flat small fuses. Since only the connecting part can be tightly held and used for connection, the space around the lamp and fuse is vacant, and the heat generated by the lamp is radiated better by convection and radiation. Since the heat is radiated well, the local temperature rise in the box frame 2 and the insulation frame 1 is minimal, and even if the inexpensive plastic box frame 2 and the insulation frame 1 are used, their thermal deformation does not occur, which is safe and economical. There is a first effect that is.

Further, in this invention, since the narrow conductive plates 6, 6 are directly attached or caulked to the pair of holding pieces 5, 5, the connection metal fittings themselves can be arranged in a space-saving manner, which is resource-saving. Automatic assembly can be performed at low cost, and there is no need for a lead wire or its crimping tool for connecting the connecting piece to another circuit, which is necessary in the prior art, or a connecting tool such as a soldering iron. Therefore, there are many effects that the connection work can be easily performed even in a narrow place such as an engine room of an automobile or a ceiling roof or a dark place.

According to the second aspect, it is possible to add the effect that the rigidity of the connector is increased and that a heat dissipation gap is generated to facilitate heat dissipation.
