Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a support connection piece suitable for use in a connector socket of a wedge base valve used in a vehicle interior light or the like.

[0002]

[Prior art]

 Conventionally, as this type of support connection piece, a strip-shaped metal plate having elasticity such as brass is bent in a U-shape from a predetermined position, and both ends are further inwardly U-turned to be bent. The flat contact terminals are formed by forming opposed contact pieces or simply U-shaped opposed contact pieces, and flat plate-shaped or flat blade-shaped so-called plate-shaped tab terminals are press-fitted between the contact pieces. A support connector with a blade receiving opposed contact piece is well known.

For example, Japanese Patent Application No. 59-67748 (see Japanese Utility Model Application Laid-Open No. 60-183374), microfilm, and Japanese Utility Model Application Laid-Open No. 2-110190, and Japanese Patent Application No. 55-158651 (Actual Application). (See Japanese Laid-Open Patent Publication No. 57-82082), Japanese Laid-Open Publication No. 2-86085, Japanese Laid-Open Publication No. 2-89792, Japanese Laid-Open Publication No. 2-124689, and Japanese Laid-Open Publication No. 60-221979. .

[Problems to be solved by the device]

 In the above-mentioned conventional techniques, since the facing surfaces of the facing contact pieces of the blade receiving terminals are flat and smooth, only flat blade-shaped or flat band-shaped terminal pieces, that is, tab-shaped tab terminal pieces are inserted and connected. However, it is not possible to hold the small diameter round rod-shaped single wire lead of small electrical components such as small and small power diodes, resistors and capacitors with double-sided lead connection type stably, and to face the round rod shaped lead. Since the contact piece is in two line contact, there are first and second serious problems that the contact resistance is large and heat is easily generated.

[0007] Incidentally, when inserting the round rod-shaped lead between the flat contact pieces and forcibly using it, the round rod-shaped lead slips on the opposing flat surface with a slight external force and escapes to the outside. The third major problem was that it would not be very useful for in-vehicle equipment, etc., because it would be displaced.

In order to eliminate the above-mentioned problems, an object of the present invention is to provide a large number of connection pieces at low cost, which are very simple and can reliably and reliably connect an electric component having a round rod-shaped lead with a small contact resistance. And

[0007]

[Means for Solving the Problems]

 The above-mentioned object of the present invention is to form two U-shaped pieces by forming both sides of a base piece connected to an elongated elastic conductive plate into a substantially U-shape and connect at least one of the facing surfaces of each piece. This could be achieved by forming concave grooves extending in the width direction on the two facing surfaces.

[0008]

[Action]

 Two U-shaped bullets are formed on both sides of a base piece connected to an elongated elastic conductive plate, and at least one of the facing surfaces has a round bar-shaped lead of an electric component up to, for example, its radius. Since the concave groove for dropping and supporting is provided, the round bar-shaped lead of the electric component is held between the concave groove surface and the bullet piece or between the opposed concave groove surfaces by firmly pressing and holding the U-shaped bullet piece so that two Conductive connection is possible in line contact. Therefore, the round rod-shaped lead of the electric component does not deviate from the bullet piece by an external force such as vibration of the automobile engine, and does not escape to the outside.

Further, according to the present invention, since the two U-shaped bullet pieces are integrally connected to the support connection piece, only one sheet metal working material is required.

[0010]

【Example】

 Examples will be described with reference to the drawings. First, as shown in FIGS. 1 and 2, the basic structure of the present invention is to connect both sides of a base piece 2 which is connected to the middle or end of an elongated elastic conductive plate 1 usually called a bus bar such as brass or phosphor bronze. As shown in FIG. 1, the two bullet pieces 3, 3 are formed in a substantially inverted U shape so as to be connected to each other, and their facing surfaces 3a, 3a are brought close to each other and face each other. In addition, as shown in FIG. 1, a concave groove 4 extending in the width direction is formed on each of the facing surfaces 3a, 3a of each of the bullet pieces 3, 3 or at least one of the facing surfaces 3a as shown in FIG. Accordingly, a sharp folding piece 3b is formed at the tip of the bullet piece 3 to form the support connection piece according to the present invention.

As shown in FIG. 2 and FIG. 3, the two U-shaped bullets 3 are arranged in parallel to the elastic conductive plate 1 in parallel with the width direction of the elastic conductive plate 1 on one side thereof. Alternatively, the shape of the groove 4 may be substantially semicircular as shown in FIG. Further, the conductive plate 1 itself is attached to the surface of the insulating substrate or the like by a known means and used.

The configuration of the support connection piece 2 according to the present invention is as described above, and an example of its use will be described below. First, as shown in FIGS. 1 and 5, the round bar-shaped lead 5a of the electric component 5 is placed between the facing surfaces 3a, 3a of the two ammunition pieces 3, 3 with the upper facing portion as shown in FIG. Push in against the elasticity of bullet 3.

When the lead 5a is further moved downward, as shown in FIG. 7, the round rod-shaped lead 5a snaps into the concave groove 4 of the facing surface 3a by the elastic force of the bullet 3 and the elastic force is applied to the round rod-shaped lead 5a. 3 can be connected tightly.

It should be noted that the movement of the lead 5a in the axial direction can be prevented by the above-mentioned supporting friction, but it can be more favorably fixed by locating the electric component 5 on the mounting member. Further, it is of course possible to insert and connect flat tab terminals between the facing surfaces 3a, 3a of the bullets 3, 3 in this invention.

[0015]

[Effect of device]

 Since the present invention is configured as described above, it has the following effects. At least one of the facing surfaces 3a, 3a of the two bullet pieces 3,3 connected to the base piece 2 of the elastic conductive plate 1 is provided with a round rod-shaped lead 5a of the electric component 5, for example, a half diameter thereof. Since the recessed groove 4 is provided so as to be depressed to a certain extent, the round bar-shaped lead 5a of the electric component 5 is pressed against the opposing recessed groove surfaces or between the recessed groove surfaces and the opposed surface 3a with sufficient elasticity of the elastic piece 3. You can hold and hold the connection.

Therefore, the round bar-shaped lead 5a of the electric component 5 does not deviate from the bullet piece 3 by an external force such as a vibration of an automobile engine, does not deviate to the outside, and does not escape to the outside, and is stably connected in a stable manner. The first effect is that the condition can be secured for a long time.

Further, according to the present invention, since the two strips 3, 3 are integrally connected to the strip-shaped wiring material composed of the elongated elastic conductive plate 1, the sheet metal working material is a single item, which is economical. There are also two effects.

Further, in this invention, since the round bar-shaped lead 5a is dropped into the concave groove 4 of the bullet piece 3, the bullet piece 3 can be supported by the elastic force of the bullet piece 3. In the case of the semi-circular shape as claimed in claim 2, since the surface contact state of the semi-circular surface of the round bar-shaped lead can be obtained, the contact resistance is lower and the heat generation is reduced as compared with the conventional two-line contact. There is also a third effect that it can be reduced.
