Description

[Detailed Description of the Invention] This invention relates to a small electronic component that can be used as a jumper wire.

Chip parts that can be used as conventional jumper wires include those that are made of an insulator with metal plating on both sides and the top surface (see Japanese Utility Model Application Publication No. 1987-87558), or those that are made of a conductive layer on a circuit board. There is a jumper wire (see Japanese Utility Model Application Publication No. 57-94970) in which an insulating layer is formed on the surface where the wires cross.

However, since both require a plating process and an insulating layer forming process, they cannot be easily and quickly manufactured using an automatic assembly machine.

This idea was made in view of the above circumstances, and it can be easily manufactured using an automatic assembly machine, and also allows the jumper wire to cross other conductive layers on the wiring board without coming into contact with them. The purpose of this invention is to provide a small electronic component that can be installed on a wiring board.

Next, an embodiment of this invention will be described with reference to the drawings.

As shown in FIG. 1, a small electronic component 10 which is an embodiment of the present invention has a first vertical section 12 that has a suspension section 11 cut out in a substantially U-shape and is erected.
, a second vertical part 13 standing parallel to the first vertical part 12 , and a horizontal part 14 connecting the first vertical part 12 and the second vertical part 13 , forming a substantially U-shape as a whole. At the same time, the first vertical portion 12 is horizontally suspended between a pair of metal electrodes 15, 15 arranged to face each other, and a suspended portion of the first vertical portion 12 in the pair of electrodes 15, 15. a rod-shaped conductor (hereinafter also simply referred to as a conductor) 16, and a resin 18 in which the first vertical portion 12 and the conductor 16 are molded.
It consists of

The small electronic component 10 having the above configuration can be manufactured, for example, as follows.

First, as shown in FIG. 2, a pair of plate-like pieces consisting of a first vertical part 12 having a substantially U-shaped notch 11, a horizontal part 14, and a second vertical part 13 are obtained by punching out a metal plate. A frame body 19 is obtained in which these are formed facing each other on the same plane. Next, the first vertical section 12
After the frame 19 is raised perpendicular to the horizontal portion 14, the frame 19 is placed on a horizontal substrate 20, as shown in FIG. After this, the first vertical part 12,1 to be erected
A conductor 16 is horizontally suspended between the two suspension parts 11, 11. At this time, in order to make the arrangement of the conductor 16 more reliable, it is preferable to electrically connect the conductor 16 and the first vertical part 12 in the suspension part 11 by soldering or the like. Then, the first
Conductor 1 supported by vertical plates 12, 12 of
A box mold 21 having a rectangular inner circumferential outline is arranged on the frame 19 so as to surround the mold 6, and a resin such as a liquid thermosetting resin is poured into the box mold 21 for a predetermined period of time. The resin is cured by heating. After the resin has hardened, the box mold 21 is removed, and then the boundary line 22 between the second vertical portion 13 and the frame 19 is cut. The horizontal part 14 and the second vertical part 13 extend at right angles to the first vertical part 12, obtained after cutting the boundary line 22, and the first vertical part 1
2, 12 and the conductor 16 molded into the resin 21 can be used as is as a small electronic component. However, the small electronic component 10 shown in FIG.
It can be obtained by standing up vertically.

As described above, the small electronic component 10 shown in FIG.
can be easily manufactured by simple steps such as punching and bending a metal plate, pouring resin, and curing. Further, since the small electronic component 10 is formed in a rectangular parallelepiped shape, it is placed on a printed wiring board, and the conductive layer on the printed wiring board and the second vertical portion 13 are electrically connected by soldering or the like. By connecting, it can be easily incorporated into a circuit.
Such a small electronic component 10 has a first vertical portion 1
2 and 12 are provided at a predetermined interval, for example, as shown in FIG. It can be incorporated into the circuit as In FIG. 4, 27 indicates the conductive layer 26 and the second vertical portion 1.
This is solder that electrically connects 3 and 3.

Although one embodiment of this invention has been described in detail above, this invention is not limited to the above embodiment, and it goes without saying that it can be implemented with appropriate modifications within the scope of the gist of this invention. Nor.

For example, the suspension part 11 is not limited to the substantially U-shape as in the above embodiment, but may have various shapes as long as the conductor 16 can be horizontally suspended between the opposing first vertical parts 12, 12. . In addition, the conductor 16
is not limited to a cylindrical shape, but can have various shapes and lengths. As described above, the second vertical portion 13 does not need to be particularly erected and may extend horizontally from the horizontal portion 14. In addition, in this invention, although molding with the resin 18 is not necessarily necessary, the first vertical portions 12, 12
It is preferable to mold the conductor 16 with a resin 18 in order to protect the horizontally extending conductor 16 and prevent it from wobbling. In the case of molding, various known thermosetting resins such as phenol resins, epoxy resins, etc. can be appropriately used as the resin 18. The resin 18 can be molded by an appropriate molding method such as transfer molding or injection molding. Further, the mold shape of the resin 18 is not limited to a rectangular parallelepiped, but may be a cylinder or other appropriate shape.

According to this invention detailed above, it can be easily manufactured using an automatic assembly machine, and can be used as a jumper wire that crosses other conductive layers on the circuit board without making electrical contact with the other conductive layers on the circuit board. It is possible to provide small electronic components that can be incorporated into.

Further, since the rod-shaped conductor is inserted into the notch formed on the vertical part of the electrode, positioning becomes extremely easy.
