BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric wire with a diode function, which has a diode function for passing a current in only one direction of the electric wire.

[0002]

2. Description of the Related Art In a vehicle or the like, a plurality of loads are often connected to a common power supply line. In this case, to prevent the surge current generated from the load from affecting other loads when the power switch of the load is turned on and off,
A diode is connected in series with the load.

Conventionally, as a method for connecting a diode in series to a power supply line, a method using a diode box has been used as shown in FIG. That is, in FIG. 4, 21 is a diode box, which is detachably attached to the electric wire connector 29. Electric wire connector 29
Is assembled by inserting a plurality of rows of female terminals 31 attached to electric wires 32 for wiring to a load through one opening of the housing 30 and exposing the other ends of the housings to their respective tips.

The diode box 21 has a connector housing 22 having a plurality of rows of male terminals 23 and a diode cover 28 having a diode 26 connected to the male terminals 23.
The connector housing 22 is formed with the fitting portion 22a of the electric wire connector 29 and the fixing portion 22b of the male terminal 23 in communication with each other, and each male terminal 23 attached to the foot of each diode 26 is attached to the connector housing 22. Each diode 26 mounted and assembled, and further protruding is integrally molded with resin to form a diode cover 28.
The diode box 21 is formed by forming the.

[0005]

In the conventional diode box 21, since the diode 26 is solidly embedded in the diode cover 28, the diode 2 is not provided.
No. 6 has a poor heat dissipation and cannot take a large current capacity. Further, since the legs of the diodes 26 are clamped to the connecting portions 24 of the male terminals 23 one by one, or soldered one by one, the workability is poor, and the diodes 26 are embedded in the diode cover 28. Since there is a resin molding process to protect it by doing so, it was troublesome. An object of the present invention is to provide an electric wire with a diode function which has a good heat dissipation characteristic and a simple structure.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described with reference to FIG. FIG. 1 is an exploded perspective view of the basic configuration of the present invention. In FIG. 1, reference numeral 1 denotes a PN junction element. For example, Si is made into an N (P) type single crystal by a CZ method, an FZ method, etc., and an PN junction is obtained by applying an epitaxial method or the like to the unidirectional A PN junction element having a diode function that allows a current to pass therethrough is formed.

Reference numerals 2 and 3 are flat conductors, and the flat conductors form electric wires. The rectangular conductors 2 and 3 are adhered to both surfaces of a flat PN junction element 1 with conductive adhesives 4 and 5, and the PN junction element 1 is sandwiched between the rectangular conductors 2 and 3. As the conductive adhesive material, for example, a conductive resin, a conductive tape or the like is used. With this configuration, an electric wire having a diode function inserted in series between the rectangular conductors 2 and 3 can be obtained.

FIG. 2 is a block diagram of the first embodiment. Figure 2
In, the PN junction element 1, the rectangular conductors 2 and 3, and the conductive adhesives 4 and 5 are as described in FIG. In the first embodiment, the rectangular conductor 3 is cut at 3A, 3B and 3C, and the rectangular conductor 3 is divided into four parts 3-1, 3-2, 3-3 and 3-4.

A battery 6 and a load 9 are provided on one of the rectangular conductors 2.
Are connected by, for example, welding or soldering, and electric power is supplied from the battery 6 to the load 9 using the rectangular conductor 2 as an electric conductor. In addition, the other divided rectangular conductors 3-2 and 3-
A load 8 is connected to the switch 3 via a switch 11, and a load 7 is connected to the switch 3 via a switch 10.

When the switch 11 is turned on, a unidirectional current flows through the battery 6, the flat conductor 2, the PN junction element 1, and the flat conductor 3-2 to the load 8, but the surge generated when the switch 11 is turned on. With respect to the current, the PN junction element 1 blocks the flow of current in the opposite direction, and does not affect the loads 7 and 9 even if the switch 10 is in the ON state.

Similarly, when the switch 10 is turned on, a unidirectional current is supplied from the battery 6 to the load 7 through the rectangular conductor 2, the PN junction element 1 and the rectangular conductor 3-3. The PN junction element 1 blocks the flow of reverse current with respect to the surge current generated by turning on and off, and does not affect the loads 8 and 9. The length when the rectangular conductor 3 is cut is determined by the current capacity and the like.

FIG. 3 is a block diagram of the second embodiment. Figure 2
The difference from the first embodiment shown in is that the outsides of the rectangular conductors 2 and 3 are covered with an insulator 12. With this configuration, the rectangular conductors 2 and 3 do not come into direct contact with other objects, and can be freely installed in any place as in the case of an ordinary insulated covered electric wire. In the second embodiment, since the rectangular conductors 2 and 3 are covered with the insulator 12, the PN junction element 1 is electrically connected to the rectangular conductors 2 and 5 without using the conductive adhesives 4 and 5. It can be held in contact with 3 and clamped.

[0016]

As described above, according to the present invention, the following effects can be obtained. A pair of flat-shaped PN junction elements that allow current to pass only in one direction are sandwiched by a pair of rectangular conductors that are electrically contacted and sandwiched by a conductive adhesive or the like.
Cut at least a part of one rectangular conductor in a rectangular conductor
Since it is then a simple structure, and it is possible to obtain a good diode function attached wire heat dissipation versus a cutting speed
Accordingly, the diode function can be increased (claims 1 and 2). Further, since the pair of rectangular conductors sandwiching the PN junction element are covered with an insulating material on the outside, wiring can be freely performed without worrying about contact with other objects (claim 3 ).
