Description

  The present invention relates to a harness having a plurality of conductors and an insulator that electrically insulates the plurality of conductors from each other.

Japanese Patent Laid-Open No. 07-1114826 Special table 2001-508585 gazette JP 05-002928 A Japanese Patent Laid-Open No. 08-273448

  Generally, a wire harness is known as a harness having a plurality of conductors and an insulator that electrically insulates the plurality of conductors from each other.

  However, in a wire harness, it is difficult for the electrical wires that are electrically paired to be wired at regular intervals, and the impedance is high, and when a large current, high frequency, or steep change current is passed, voltage drop or radiation noise It may cause problems such as occurrence.

  In view of this, a harness having a plurality of conductors and an insulator that electrically insulates the plurality of conductors from each other and having the following low impedance has been proposed.

First, a conductive path for supplying a current to the load, which is a forward path for a current to be supplied to the load, a return path for a current to be supplied to the load, and the forward path conductive plate And a conductive path comprising an insulating layer sandwiched between the return path conductive plates (see Patent Document 1).
According to this, a high-frequency large current can be supplied to the load. In addition, noise generated by high-frequency current is reduced, and electromagnetic interference (EMI) can be reduced.

Second, it comprises a first substantially flat conductor and a second substantially flat conductor, the two conductors being mounted substantially in parallel and separated by an insulator; At least one of the conductors is a distribution line for distributing high-frequency alternating current provided in association with an element made of a material having a high relative magnetic permeability (see Patent Document 2).
According to this, if the above distribution line is used so that the voltage applied to one conductor is equal to and opposite to the voltage applied to the other conductor with respect to the ground, in other words, If the voltage is always a DC voltage of opposite polarity or an alternating voltage that is in reverse phase with respect to ground potential, the electric field produced by the system is considered to be very small.

  However, in the above harness, since the conductor is a flat plate, it is hard and processing such as bending or cutting into a predetermined shape is extremely difficult.

  Therefore, in order to solve the problems in the harness in which the conductor is a flat plate, the following harness having a structure that is easy to bend has been proposed.

First, a flat power cable in which a plurality of conductors made of stranded wires are arranged in parallel, and an insulating layer made of cross-linked polyethylene and a vinyl sheath are sequentially provided around the conductor, the insulating layer made of cross-linked polyethylene covering the entire circumference. A flat power cable for a low-voltage trunk line, characterized by having a uniform thickness and having a gap or inclusion in a valley-like portion formed between adjacent stranded conductors (see Patent Document 3).
According to this, since the insulation layer of the cross-linked polyethylene is applied around the conductors arranged in parallel in a uniform thickness over the entire circumference, the thickness of the cross-linked polyethylene layer itself is partially increased. The problem that the bending rigidity becomes large can be solved, and the insulating layer of the cross-linked polyethylene is positively separated by the fact that the layer itself has a certain thickness and the valley portion formed between the adjacent conductors. Since voids are formed, combined with the fact that the cross-linked polyethylene layer can reduce the bonding area to the conductor, the resistance against bending from the flat surface side can be kept small.

Second, a first conductive line assembly including a plurality of first conductive lines arranged in parallel and in a row and insulated from each other, wherein the plurality of first conductive lines are electrically connected at both end portions; The first conductive line structure includes a plurality of second conductive lines that are arranged in a line substantially parallel to each other and that are insulated from each other, and the plurality of second conductive lines are arranged at both end portions. Provided between the electrically connected second conductive line structure and the first and second conductive line structures, the distance between the corresponding conductive lines of the first and second conductive lines is made substantially constant. A flexible conductive line structure including an insulator to be maintained (see Patent Document 4).
According to this, since it is flexible (flexible) because it is a three-layer structure of two conductive line structures and an insulator, it can be bent easily, which is extremely convenient in the case of a circuit configuration or the like.

  However, in the above prior art, by arranging a plurality of conductors in parallel, the same effect as that of a flat conductor is obtained, but the first conductor and the first conductor having a plurality of conductors arranged in parallel When the two conductors are arranged in parallel to the direction perpendicular to the diameter direction of the conductors with respect to the parallel direction, the first conductor and the second conductor are uneven because the first conductor and the second conductor are in the parallel direction. There is a problem that the distance from the conductor is not constant and the impedance is not stable. In addition, although a plurality of conductive wires are arranged in parallel so as to be easily bent, there is a possibility of disconnection depending on the magnitude of bending stress.

  Accordingly, the present invention has been made to solve the above-described problems of the prior art, and the object of the present invention is to ensure that a large current, a high frequency, or a steep change current flows, and a low impedance and stable It is an object of the present invention to provide a harness that can be formed in a desired shape without reducing the occurrence of voltage drop and radiation noise under such conditions, and without bending stress acting on the conductor.

That is, the present invention includes a first conductor and a second conductor formed in a long flat plate shape, and an insulator for electrically insulating the conductor, and the first conductor and the second conductor. The planes including the long sides of the cross section in the short direction are arranged parallel to each other with a predetermined distance from each other, and the first conductor and the second conductor include the mutual distance and the first conductor. And a harness in which an insulator is provided around the end of the second conductor excluding the end face in the longitudinal direction, the harness being composed of a harness block formed at a predetermined distance with respect to the longitudinal direction. The harness is characterized in that the end face is formed in a desired shape by connecting the first conductor and the second conductor so as to be electrically connected between the harness blocks.
According to this, it is ensured that a large current, a high frequency, or a steeply changing current flows, a voltage drop and a generation of radiation noise under a stable state with low impedance, and a bending stress does not act on the conductor. A harness that can be formed into a desired shape can be provided.

  In the present invention, the harness block is formed in a linear shape, a bent shape bent in a predetermined direction, a predetermined number and a branched shape branched in a predetermined direction, or a combination thereof.

  In the present invention, the insulator provided around the end of the harness block excluding the end face in the longitudinal direction is preferably a magnetic material that can electrically insulate the first conductor and the second conductor. According to this, generation of radiation noise radiated from the harness can be further reduced.

  Further, in the present invention, the end face in the longitudinal direction of the harness block is contrasted from the central portion of the interval between the first conductor and the second conductor toward the shorter thickness direction of the first conductor and the second conductor. In this case, the contact area of the first conductor and the second conductor between the harness blocks can be increased.

  Further, in the present invention, the end portion in the longitudinal direction of the harness block is preferably formed with an engaging portion so that the end surface in the longitudinal direction of the harness block is pressed between the harness blocks. The connection between the first conductor and the second conductor between the harness blocks can be surely and easily performed.

  Moreover, in this invention, the latching | locking part which latches a harness block to the predetermined location of an apparatus is formed in the predetermined location of the harness block.

  Further, in the present invention, the first conductor or the second conductor in the harness block may be divided in parallel with each other in the longitudinal direction and electrically insulated from each other. A harness for signal input / output of the device can be formed.

  According to the present invention, it is ensured that a large current, a high frequency, or a steeply changing current flows, a voltage drop and a generation of radiation noise under a stable state with low impedance, and a bending stress acting on a conductor. A harness that can be formed into a desired shape without any problems can be provided.
