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 all of the above-mentioned conventional techniques, since the facing surfaces of the facing contact pieces of the flat blade receiving terminal are flat surfaces with a slip, only flat blade-shaped or flat strip-shaped terminal pieces, that is, tab-shaped tab terminal pieces are inserted and connected. However, it is not possible to stably hold the small diameter round bar-shaped single wire lead of small-sized and low-power diodes, resistors, capacitors, and other electrical parts with double-sided lead connection type electrical parts, and face the round bar-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 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 slender elastic conductive plate into a substantially U-shape and to form a support connection piece having an opposing elastic piece. The opposing pieces are connected to both sides of the protruding piece projecting from one side of the base. At the same time, it can be achieved by projecting a projecting piece on the end side of the projecting piece so as to face the outer edge of the facing piece, and forming a groove on the slit edge formed on the facing piece or on the outer surface of the projecting piece. It was

[0008]

[Action]

 A round rod-shaped lead of an electric component is dropped, for example, up to about its radius to support a slit formed in an opposing piece connected to the base of the splicing support piece or a bullet piece approaching the outer edge of these facing pieces. Since the concave groove is provided, the round bar-shaped lead of the electric component can be electrically connected between the concave groove surface and the bullet piece or the slit by firmly pressing and holding the bullet piece with the elastic force of the bullet piece.

Therefore, the round rod-shaped lead of the electric component does not deviate from the opposing piece or the bullet piece by an external force such as vibration of an automobile engine, and does not escape to the outside. Further, in this invention, since the opposing piece and the bullet piece are integrally connected to the support connecting 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 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, one side of the base 2a is further bent at both sides of the protruding piece 3a which is erected via the bending portion to further connect the opposing pieces 3 and 3 and the upper side of the protruding piece 3a is further bent obliquely. Then, the bullet piece 4 is integrally erected, and the slits 3b and 3b along the projecting piece 3a are cut in the facing pieces 3 and 3, respectively.

Further, as shown in FIGS. 1 and 5, a concave groove 5 is formed in the vicinity of the bottom of the slit 3b of the facing piece 3 so as to extend outward, or as shown in FIG. The recessed groove 5 extending in the direction is formed to form the support connection piece according to the present invention. In addition, as shown in FIG. 3, the opposing piece 3 is continuously connected to the projecting piece 3a in the base 2a of the support connection piece 2 in a direction orthogonal to the projecting direction of the opposing bullet pieces 1,1. Alternatively, as shown in FIG. 4, the facing pieces 3 and 3 may be connected from one side of the base portion 2a toward the facing direction of the facing bullets 1 and 1. Further, the support connection piece 2 itself is attached by a well-known means to the projection of the mounting hole of the insulating base through the mounting hole 2b or 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 6a of the electric component 6 is indicated by the arrow in FIG. 5 by aiming the upper part of the slit between the slits 3b, 3b of the facing pieces 3, 3 and the bullet piece 4. As shown in FIG. 6, the lead 6a is applied to the bullet 4 as shown in FIG. 6, and the lead 6a is pushed into the slit 3b against the elasticity of the bullet 4 as shown by the arrow in FIG. When it is moved to the left, the round bar-shaped lead 6a snaps into the concave groove 5 of the opposing piece slits 3b, 3b (bullet piece 4 in FIG. 2) by the elastic force of the bullet piece 4 as shown in FIG. It is possible to connect it by a flexible support such as the elasticity of the above, and by energizing a well-known wedge base valve 7 supported between the opposing projectiles 1 and 1 in FIG.

Although the movement of the lead 6a in the axial direction can be prevented by the above-mentioned support friction, it can be more favorably fixed by locating the electric component 6 on the mounting member. In addition, a flat plate tab terminal can of course be inserted and connected between the bracelet piece 3 and the opposing piece slit 3b in this invention.

[0014]

[Effect of device]

 Since the present invention is configured as described above, it has the following effects. On the both sides of the projecting piece 3a connected to the base portion 2a of the support connection piece 2, the slits 3b and 3b of the facing pieces 3 and 3 or the bullet 4 which is brought close to the outer edge of the facing piece 3 and 3, the circular shape of the electric component 6 Since the concave groove 5 for supporting the rod-shaped lead 6a by dropping it to the radius is provided, the round rod-shaped lead of the electric component is pushed between the concave groove surface and the bullet 4 or the slit 3b by the elasticity of the bullet 4. It can be tightly pressed and held to make a continuous connection.

Therefore, the round rod-shaped lead 6a of the electric component 6 does not deviate from the opposing pieces 3, 3 and the slit 3b and the bullet 4 by the external force such as the vibration of the automobile engine, and escapes to the outside. Without any reason, there is the first effect that the stable connection can be secured for a long time.

Further, according to the present invention, since the opposing piece 3, the bullet piece 4, the slit 3b and the concave groove 5 are continuously formed on the plate in the supporting plate connecting piece, only one sheet metal working material is required, which is economical. There is also a second effect.

Further, according to the present invention, when the round bar-shaped lead 6a has the facing piece slit 3b and the concave groove 5 of the bullet piece 4 is arcuate as in claim 3, a surface contact state with the peripheral surface of the round bar-shaped lead can be obtained. Therefore, there is a third effect that the contact resistance becomes lower and heat generation can be reduced as compared with the conventional two line contact type.
