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]

 For this type of support connection piece, conventionally, a strip-shaped metal plate having elasticity, such as brass, is bent in a U shape from a predetermined place, and both ends are further U-turned inward and bent. A flat blade in which opposed contact pieces are formed, or a simple U-shaped opposed contact piece is provided, and flat plate-shaped or flat blade-shaped so-called plate-shaped tab terminals are press-fitted between the contact pieces to connect them. A support connector with a receiving and opposing 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 stably pinch and connect the small-diameter round bar-shaped single wire lead of the electric parts of the both side lead connection type such as small power diode, resistor and capacitor, and the round bar-shaped lead and the opposing contact piece. Since there are two line contacts, 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 connecting pieces at low cost, which are very simple and can reliably and reliably connect electrical parts having round bar leads with less contact resistance. And

[0007]

[Means for Solving the Problems]

 The object of the present invention described above is to form a flexible connecting piece having an opposing elastic piece by molding an elongated elastic conductive plate into a substantially U shape, and to connect a substantially U-shaped elastic elastic piece to one side of its base. In addition, the end piece was brought close to the base piece to face each other, and the base piece or the end piece of the flannel bullet piece was formed into a W shape to form a valley extending in the width direction. .

[0008]

[Action]

 The base part of the supporting member is partially U-turned to form an articulation, and the base member of the supporting member or the end part of the supporting member that faces the base member is processed into a W-shape for electrical processing. Since a valley is provided to support the round bar-shaped lead of the component by dropping it to about that radius, for example, the round bar-shaped lead of the electrical component is held between the outer surface of the above-mentioned valley and the end piece by pressing the elastic support piece with sufficient elasticity. Then, conductive connection can be made in three line contact states.

Therefore, the round rod-shaped lead of the electric component does not deviately move with respect to the flannel bullet by external force such as vibration of the automobile engine, and does not escape to the outside.

Further, according to the present invention, since the support bullet piece is integrally connected to the support connection piece, only one sheet metal working material is required. Further, the round rod-shaped lead can obtain three line contact portions with respect to the flannel bullet piece.

[0011]

EXAMPLES 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 that a slender elastic conductive plate such as brass or phosphor bronze is formed into a substantially U shape as shown in FIG. Make the connection piece 2. Then, a substantially U-shaped support bullet piece 3 is continuously provided on one side of the base portion 2a, and an end piece 3b is brought close to the base piece 3a to face each other.

Further, as shown in FIG. 1, by forming the end piece 3b of the flannel bullet 3 or the base piece 3a into a W shape as shown in FIG. 2 and forming a valley 4 extending in the width direction thereof. The support connection piece 2 according to this invention is constructed.

Note that, as shown in FIG. 3, the direction of continuous installation of the support bullet pieces 3 with respect to the base portion 2a of the support connection piece 2 is such that the base portion 2 of the support piece 2 is directed in the direction opposite to the protruding direction of the opposing bullet pieces 1,1. It may be continuously provided on one side, or as shown in FIG. 4, the support bullet pieces 3 may be connected from one side of the base portion 2a toward the projecting direction of the opposing bullet pieces 1,1. Further, the support connection piece 2 itself is attached by a well-known means such as an edge projection of an attachment hole of the insulating base through the attachment hole 2b and the like, 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 attached to the upper part 3c between the base piece 3a and the end piece 3b of the orthodox bullet piece 3 as shown in FIG. And push it against the elastic force of the support piece 3.

When the lead 5a is further moved downward, the round bar-shaped lead 5a snaps down into the valley 4 of the end piece 3b (base piece 3a in FIG. 2) by the elasticity of the support bullet piece 3 as shown in FIG. It is possible to make a tightly-supported connection with the elasticity of the piece 3b, and it is possible to energize a well-known wedge base valve 6 that is provided between the opposing bullet pieces 1 and 1 in FIG.

Further, a flat plate-shaped tab terminal can of course be inserted and connected between the base piece 3a and the end piece 3b of the support bullet piece 3 in the present invention.

[0017]

[Effect of device]

 Since the present invention is configured as described above, it has the following effects. A round bar-shaped lead 5a of the electric component 5 is attached to the base piece 3a of the support piece 3 connected to the base portion 2a of the support connection piece 2 or the end piece 3b of the support piece 3 that is brought close to and facing the base piece 3a. Since a valley 4 is formed by, for example, a substantially W-shaped cut and raised to support by dropping it to about its radius, a round bar-shaped lead of an electric component is inserted between the outer surface of the valley and the end piece 3b. The elastic force of the piece 3 allows it to be pressed and held tightly to establish a conductive connection.

Therefore, the round bar-shaped lead 5a of the electric component 5 does not deviately move with respect to the orbital support piece 3 by an external force such as vibration of an automobile engine, and does not escape to the outside and is stable. There is a first effect that the support connection state can be secured for a long time.

Further, according to the present invention, since the support bullet piece 3 is integrally connected to the support connection piece, the sheet metal working material is a single piece, which is economical, and the support bullet piece 3 is W-shaped. Since the valley 4 is formed by molding, it also has the second and third effects that sheet metal working is easy.

Further, in this invention, since the round bar-shaped lead 5a can be firmly supported by the elastic force of the end piece 3b while the round bar-shaped lead 5a is dropped in the valley 4 of the support bullet piece 3, the three line contact portions and the valley 4 are claimed. In the case of the semi-circular shape as described in Item 3, since the surface contact state with the semi-circular surface of the round bar-shaped lead can be obtained, the contact resistance is at least about 67% as compared with the conventional two-line contact. Therefore, there is a fourth effect that heat generation can be reduced.
