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 bends a conductive metal plate in a U shape. It is composed of a holder main body formed and a mounting piece formed integrally with the main body so as to extend in a direction opposite to the U-shape. Center pieces and left and right side pieces are provided to face each other at intervals above and below the recess, and the holder body is fitted into a fitting recess formed in the housing, so that the U-shaped portion of the holder body is aligned with the center piece. An indoor small lamp for an automobile, characterized in that it is sandwiched between 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.

[0003]

[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, it is necessary to perform a post-processing connection by manual work such as caulking with a rivet. The second major problem was that automatic assembly of the lamp was extremely difficult.

In order to eliminate the above-mentioned problems, the present invention integrally installs a relatively small holder for holding a wedge base valve or the like on a relatively large plastic substrate, thereby making it inexpensive and inexpensive. The objective is to secure a reliable valve and fuse holding structure, and to automate the connection and mounting of the connection tool to the other circuit including the attachment of the holder to the holder.

[0006]

[Means for Solving the Problems]

 The above-mentioned object of the present invention is to integrally use an insulating holder having a connecting tool integrally molded on a member to be mounted, and to use a plastic substrate on which a cylindrical insulating base frame is integrally erected, and the insulating member. A pair of projections formed on the opposing inner surface of the base frame, and an elastic conductive plate formed into a substantially U shape, and two connecting members each having a pair of sandwiching pieces and a narrow conductive plate connected to the base of the sandwiching piece. This can be achieved by mounting these two connectors in parallel between the opposing inner surfaces via the pair of protrusions in the mounting holes formed near the base of the sandwiching piece.

[0007]

[Action]

 A relatively small insulating base frame is integrally projected on a relatively large area plastic substrate, and a pair of connecting pieces mounted in parallel by concave and convex engagement in this insulating base frame only connects the wedge base lamp and the flat small fuse. It can be used by holding it tightly. Therefore, the space around the lamp and fuse is vacant, and the heat generated by the lamp, etc. is radiated well by convection and radiation, and the heat of the connector is radiated well by the narrow conductive plate connected to it. The local temperature rise in is minimal.

【Example】

 Examples will be described with reference to the drawings. First, the basic structure of the present invention is that a simple heat-resistant and inexpensive plastic such as polypropylene is used for constructing a connector mounting structure by attaching an insulating holder to which a connector is mounted to a member to be mounted. As shown in Fig. 3, the base plate 2 is formed into a rectangular cylindrical frame shape as shown in Fig. 1. The insulating base frame 1 is provided with protrusions 4 and 4 as shown in Fig. 3 on the opposing inner surfaces 1a and 1a. The conductive plate is formed into a substantially U shape as shown in FIG. 1, and has a pair of holding pieces 5 and 5, and a small width conductive plate 6 such as a bus bar integrally projecting on the base 5a of the holding pieces 5 and 5. Two other connectors 7, 7 are inserted into the insulating base frame 1 as shown in FIGS. The narrow conductive plate 6 may be fixed to the holding piece base portion 5a by crimping with a coupling element 6a such as a rivet as shown in FIG. 8 or by soldering.

At the time of the above-mentioned insertion, the holding pieces 5, 5 are formed near the base 5a of the holding piece 5 while inserting the holding pieces 5 between the opposing inner surfaces 1a, 1a of the base frame 1 while shrinking against the elasticity. The projections 4 and 4 forming the pair are engaged in the mounting holes 8 and 8 by elastic return of the snap and the connecting piece 5, and the connecting tools 7 and 7 are shown on both sides between the base frame facing inner surfaces 1a and 1a, respectively. As shown in FIG. 3, the valve holder 9 is constructed as a whole by fitting the narrow width conductive plate 6 in the concave groove 2a of the substrate 2. 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.

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 its connecting base from the state shown by the chain line in FIG. 4 as shown by the solid line in FIG. 4 and as shown in FIGS. At this time, first, the valve base 12b is inserted until it contacts the holder edge 9a while pushing the lead pieces 12a, 12a of the valve 12 between the holding pieces 5, 5 of the connecting tool 7 against the resilience of these pieces. As a result, the bulb 12 can be inserted into the holder 9 as shown in the above figures, and the wedge base valve 12 can be turned on by energizing the narrow conductive plates 6, 6. A well-known flat fuse may be inserted and used instead 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. A relatively small insulating base frame 1 is integrally projected on a relatively large area plastic substrate 2, and a pair of connecting pieces mounted in parallel inside this insulating base frame 1 by concave and convex engagement is used for wedge base lamps and flat small fuses. Since it can be used by tightly holding only the connection part of the lamp, the space around the lamp and fuse is vacant, the heat of the lamp and the like is radiated well by convection and radiation, and the heat of the connection tools 7, 7 is small conductive plate 6. Since the heat is radiated better, the local temperature rise of the substrate 2 and the base frame 1 is minimal, and even if an inexpensive plastic substrate 2 or base frame 1 is used, its thermal deformation does not occur and it is safe and economical. There is the first effect that it has.

Further, in this invention, the narrow conductive plates 6, 6 are directly attached or caulked to the pair of holding pieces 5, 5, so that the connection 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.
