[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a support connection piece that can stably and reliably connect a round bar-shaped lead such as an electric component to an electric wiring member, which is generally called a bus bar, that is, a small-width conductive plate.

[0002]

[Prior art]

 Conventionally, a small flat plate terminal piece, so-called tab terminal supporting connection piece, is a strip-shaped metal plate having elasticity such as brass, which is conventionally bent from a predetermined position into a U-shape, and both ends thereof are further inwardly bent from each other. U-turned and bent to form opposing contact pieces, or a single U-shaped opposing contact piece is provided, and a flat strip-shaped or flat blade-shaped so-called plate-shaped tab terminal is press-fitted between these contact pieces. It is well known that a flat-blade-bearing opposed contact piece that is adapted to be connected to each other is used.

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 leads of small-sized and small-power diodes, resistors, capacitors, and other electrical parts that are connected on both sides with lead wires. Since and are two line contacts, there are first and second serious problems that 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 an elongated elastic conductive plate partly in a substantially U-shape and connect opposing pieces having vertical slits in series, and connect the upright pieces between the upright pieces to each other. This can be achieved by providing a groove that extends in the width direction of the lower part of the slit or the opposing piece of the support bullet piece.

[0008]

[Action]

 A round rod-shaped lead of an electrical component is dropped, for example, up to about its radius into a slit of an opposing piece connected to a part of an elongated elastic conductive plate or a flared bullet piece formed in an upright piece by approaching this slit to form a recess for supporting it. Since the groove is provided, the round rod-shaped lead of the electric component can be conductively connected between the concave groove surface and the flannel bullet piece by firmly pressing and holding the elastic piece of the bullet piece. Therefore, the round rod-shaped lead of the electric component does not unnecessarily shift its position with respect to the flannel bullet or the opposing slit by external force such as vibration of the vehicle engine, and does not escape to the outside.

Further, according to this invention, since the facing piece, its slit, the upright piece, and the flannel piece are integrally connected to the elongated conductive plate, a single sheet metal working material is required. Furthermore, in this invention, the round bar-shaped lead can be supported by the elastic force of the supporting bullet piece while being dropped into the slit of the opposing piece slit or the concave groove of the supporting bullet piece, so that the three line contact states and the concave groove are half. In the case of the arc shape, it is possible to obtain a surface contact state with the semi-circular surface of the round bar-shaped lead.

【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 long and narrow elastic conductive plate 1 made of brass, phosphor bronze, or the like, that is, a so-called bus bar in the middle or near the terminal is partially U-shaped in the width direction. Forming and arranging facing pieces 2 and 2 in series, the upright piece 3 in the middle of each piece is connected to the flannel bullet piece 4, and at the bottom of the slit 2a vertically installed in the facing piece 2 or in FIG. As described above, the recessed groove 5 extending in the widthwise direction is formed in the support bullet piece 4 to form the support connection piece according to the present invention.

Note that the projecting portions and directions of the facing piece 2 and the supporting bullet piece 4 with respect to the conductive plate 1 can be variously modified and modified as shown in FIGS. 3 and 4, respectively.

The structure of the support connection piece according to the present invention is as described above, and its use example will be described below. First, as shown in FIGS. 1 and 5, aiming at the upper part of the slit between the slits 2a of the facing pieces 2 and 2 and the flannel bullet piece 4, the round bar-shaped lead 6a of the electric component 6 is arranged as shown in FIG. Push in against the resilience of the support piece 4.

When the lead 6a is further moved downward, the round bar-shaped lead 6a is moved by the elastic force of the flannel bullet 4 into the concave groove 5 of the opposing pieces 2 and 2 (the holding bullet piece 4 in FIG. 2) as shown in FIG. It snaps in and the round bar-shaped lead 6a can be tightly connected to the opposing pieces 2 and 2 by the elasticity of the support bullet piece 4.

Although the movement of the lead 6a in the axial direction can be prevented by the above-mentioned supporting 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 flannel bullet piece 4 and the opposing piece slit 2a in this invention.

[0015]

[Effect of device]

 Since the present invention is configured as described above, it has the following effects. A slit of opposing pieces 2,2 connected to a part of a slender elastic conductive plate 1 or an upright piece 3 between the opposing pieces 2 and 2 has a round bar-shaped electrical component 6 attached to a supporting piece 4 Since the concave groove 5 for supporting the lead 6a by dropping it to the radius is provided, the round bar-shaped lead 6a of the electrical component 6 is provided between the concave groove surface and the flannel bullet piece 4 and It is possible to connect it by holding it tightly with 4 elastic pressure.

Therefore, the round rod-shaped lead 6a of the electric component 6 does not deviate from the support bullet piece 4 and the opposing pieces 2 and 2 by the external force such as the vibration of the automobile engine, and escapes to the outside. The first effect is that the stable connection can be secured for a long period of time.

Further, according to the present invention, since the opposing pieces 2, 2 and the slender bullet pieces 4 are connected and formed to one plate on the elongated conductive plate, the second effect that the sheet metal working material is a single item and is economical. There is also.

Further, in this invention, the round bar-shaped lead 6a is dropped into the concave groove 5 of the slit 2a of the facing piece 2 or 2 or the concave groove 5 of the flannel bullet 4 so that the elastic force of the flannel bullet 4 can be applied. Since it can be supported tightly, three line contact states can be obtained, and when the concave groove 5 is arcuate as in claim 3, it is possible to obtain a surface contact state with the peripheral surface of the round bar-shaped lead, so The third effect is that the contact resistance is lower and the heat generation can be reduced, compared to the case where the two line contacts are used.
