Description

[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]

 As a small flat plate terminal piece, a so-called tab terminal supporting connection piece, a strip-shaped metal plate having elasticity such as brass is bent in a U shape from a predetermined place, and both ends thereof are further inwardly bent to each other by U. One that is turned and bent to form an opposing contact piece, or a simple U-shaped opposing contact piece is provided, and flat band-shaped or flat blade-shaped so-called plate-shaped tab terminals are press-fitted between these contact pieces to connect. The support connector with the flat blade receiving facing contact piece is 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 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 above-mentioned object of the present invention is to form an elongated elastic conductive plate partially in a substantially "-" shape so as to connect a base piece and a splint bullet piece that closely faces the inner surface of the base piece. Alternatively, it can be achieved by forming a concave groove extending in the width direction on the flannel bullet piece.

[0008]

[Action]

 A groove for supporting a round rod-shaped lead of an electric component is provided on a base piece connected to a part of an elongated elastic conductive plate or on a flannel bullet piece formed close to and facing this base piece, for example, by dropping the round rod-shaped lead of the electric component to about its radius. Therefore, the round rod-shaped lead of the electric component can be conductively connected between the concave groove surface and the supporting bullet piece by firmly holding the elastic force of the bullet piece. Therefore, the round rod-shaped lead of the electric component does not deviate from the flannel bullet or the base piece by the external force such as the vibration of the automobile engine, and does not escape to the outside.

Further, according to the present invention, since the base piece and the flannel bullet piece are integrally connected to the elongated conductive plate, a single sheet metal working material is sufficient. Further, in this invention, since the round bar-shaped lead is dropped into the groove of the base piece or the support bullet piece, it can be supported by the elasticity of the support bullet piece so that the three line contact states and the groove are semicircular. In the case of the arc shape, it is possible to obtain a surface contact state with the semi-circular surface of the round rod-shaped lead.

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 to form an elongated elastic conductive plate 1 made of brass, phosphor bronze, or the like in the middle or near the end of the elastic conductive plate 1 in a substantially "-" shape in the width direction. Then, the base piece 2 and the flannel bullet piece 3 that closely approaches and faces the inner surface of the base piece 2 are connected to each other, and the base piece 2 or the flank bullet piece 3 is provided with a groove 4 extending in the width direction thereof as shown in FIG. Then, the supporting connection piece according to the present invention is formed.

Note that the projecting portions and directions of the base piece 2 and the flannel bullet piece 3 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, the round bar-shaped lead 5a of the electric component 5 is sandwiched as shown in FIG. 6 by aiming the upper facing portion 3a between the base piece 2 and the flannel bullet piece 3. Push in against the elasticity of the support piece 3.

When the lead 5a is further moved downward, the round bar-shaped lead 5a snaps into the concave groove 4 of the base piece 2 (the holding bullet piece 3 in FIG. 2) by the elasticity of the flannel bullet piece 3 as shown in FIG. When it falls, the round bar-shaped lead 5a can be tightly supported by the elasticity of the two pieces 2,3.

The movement of the lead 5a in the axial direction can be fixed by locating the electric component 5 on the mounting member. In addition, a flat tab terminal can of course be inserted and connected between the orthodox bullet piece 3 and the base piece 2 in this invention.

[0015]

[Effect of device]

 Since the present invention is configured as described above, it has the following effects. The round rod-shaped lead 5a of the electric component 5 is dropped to, for example, the radius of the base piece 2 formed to be connected to a part of the elongated elastic conductive plate 1 or the flannel bullet piece 3 formed facing the base piece 2 so as to face each other. Since the concave groove 4 that is supported by is provided, the round bar-shaped lead of the electric component 5 can be conductively connected between the concave groove surface and the slidable bullet piece 3 mainly by elastically pressing and holding the elastic piece 3 firmly. ..

Therefore, the round bar-shaped lead 5a of the electric component 5 does not deviate from the support bullet piece 3 and the base piece 2 by the external force such as the vibration of the vehicle engine, and should escape to the outside. In addition, there is the first effect that it is possible to stably maintain the support connection state for a long time.

In addition, the present invention has the second effect that it is economical because the base piece 2 and the slender bullet piece 3 are integrally connected to the elongated conductive plate, and that the sheet metal working material is a single piece.

Further, in this invention, since the round bar-shaped lead 5a is dropped into the concave groove 4 of the base piece 2 or the support bullet piece 3, it can be supported by the elasticity of the support bullet piece 3, so that three lines When the contact state or the concave groove 4 is a semi-circular shape as claimed in claim 3, it is possible to obtain a surface contact state with the semi-circular surface of the round bar-shaped lead. However, the contact resistance is at least about 67%, and the third effect is that heat generation can be reduced.
