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 stably pinch and connect the small diameter round bar-shaped single wire leads of small electric components such as small power diodes, resistors, capacitors, etc. with double-sided lead connection type. 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 object of the present invention described above is to provide a base piece connected to an elongated elastic conductive plate with a substantially U-shaped supporting bullet piece continuously, and to form a constriction portion in the middle thereof, and to sandwich the constriction portion. This can be achieved by forming a guide slope and a bag surface on both sides of the support bullet piece.

[0008]

[Action]

 Since the guide slope and the bag surface are formed on both sides of the constriction section provided in the middle of the splendid bullet piece connected to the middle and end of the slender elastic conductive plate, the circular shape of the electrical component is passed through the guide slope. By supporting the rod-shaped leads by dropping them into the bag surface against the elastic force of the constriction portion, the round rod-shaped leads of electric parts are pressed and held as tightly as possible in the bag surface by the elastic force of the clip. Conductive connection can be made to the branch connection piece. 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, a single sheet metal working material is sufficient. Furthermore, the round rod-shaped lead can obtain at least three line contact portions with respect to the flannel bullet pieces, and can also obtain a good surface contact state when the bag surface is an arc shape.

[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 one side of a base piece 2 connected to the middle or end of an elongated elastic conductive plate 1 usually called a bus bar, such as brass or phosphor bronze, is connected to one side. A series of U-shaped flannel bullets 3 are provided in series, and a constricting part 4 is formed in the middle of the flannel, which is inserted into the upper and lower sides of the flannel projecting piece 3 with the constricting part 4 sandwiched therebetween. The guide slope 3a of the reed and the non-circular bag surface 4a, for example, are formed to form the support connection piece according to the present invention. The constricting portion 4 may be formed into a rectangular shape as shown in FIG. 2, or may be formed only on one side of the flannel bullet piece 3 as shown in FIG.

Further, as shown in FIG. 2, the flank bullet pieces 3 are continuously arranged with respect to the conductive plate 1 along one side of the base piece 2 in the width direction of the conductive plate 1, or as shown in FIG. As described above, the flared bullet pieces 3 may be continuously provided from one side of the base piece 2 protruding between the conductive plates 1 toward the thickness direction of the conductive plate 1. The conductive plate 1 itself is attached to the surface of the insulating substrate or the like by a known means for use.

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 by the arrows in FIG. 1 and FIG. 5, the round bar-shaped lead 5a of the electric component 5 is moved downward by aiming at the constricted portion 4 from the upper slope 3a of the flannel bullet piece 3, and as shown in FIG. Defensively, push down by pushing downward as shown by the arrow against the elasticity of the bullet 3.

When the lead 5a is further moved downward, the round bar-shaped lead 5a spreads the constricted part 4 against its elasticity as shown in FIG. As shown in the figure, the round rod-shaped lead 5a can be firmly connected to the support elastic piece 3 by the elasticity of the support surface 4a. The movement of the round bar-shaped lead 5a in the axial direction can be prevented by the above-mentioned support friction, but it can be more favorably fixed by locating the electric component 5 and the like on the mounting member.

[0014]

[Effect of device]

 Since the present invention is configured as described above, it has the following effects. Since the guide slope 3a and the bag surface 4a are formed on both sides of the constriction part 4 provided in the middle of the substantially U-shaped support bullet piece 3 connected to the elongated elastic conductive plate 1, the guide slope 3a is formed. After expanding the round bar-shaped lead 5a of the electric component 5 against the elastic force of the constricting portion 4, it is dropped into the bag surface 4a and supported by the elastic force of the bullet piece 3, whereby the round bar-shaped lead of the electric component 5 is supported. The elastic force of the support bullet piece 3 allows the support piece 5a to be pressed and held tightly in the bag surface 4a to be conductively connected to the support connection piece 2.

Therefore, the round rod-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 elastic support piece 3 is integrally connected to the strip-shaped wiring material, the sheet metal working material is a single piece, which is economical, and the elastic support piece 3 is almost U-shaped. Since the constricted portion 4 and the bag surface 4a are formed by forming a letter shape, it has the second and third effects that it is easy to process the sheet metal working material as a single piece and is economical.

Further, in this invention, since the round bar-shaped lead 5a is dropped into the bag surface 4a of the orthotic bullet piece 3 via the constriction section 4, the elastic orbital bullet piece 3 can be elastically supported. When the three line contact parts and the bag surface 4a are arcuate as in claim 2, a surface contact state can be obtained with most of the peripheral surface of the round bar-shaped lead, so that the above two conventional line contacts are used. In comparison with the above, there is a fourth effect that the contact resistance is greatly reduced and heat generation can be reduced.
