As a result, the power supply wires 31p, 32p do not get congested, making it easy to manufacture the connecting member-equipped multicore cable 1 and to use it easily. In addition, since the first feeder group 30C and the second feeder group 30D do not overlap in the vertical direction of the connecting member-equipped multi-core cable 1, the thickness of the connecting member-equipped multi-core cable 1 can be reduced.

The sequence of can be any sequence. By arranging this arbitrary arrangement in the easy arrangement order in manufacturing, the manufacturing operation of the multifilament cable 1 with connecting members becomes easy.

<Example of arrangement of second connection member 4>
As shown in FIG. 2, a plurality of contacts 42 a, 42 b, 42 p, 43 a, 43 b and 43 p are arranged in a line on one surface (for example, the upper surface 41) of the second connection member 4.
The first feed line group 30C is electrically connected to the three contacts 42p. Electric power supply wires 31p are connected to the contacts 42p, respectively. The second feed line group 30D is electrically connected to the three contacts 43p. Electric power supply wires 32p are connected to the contacts 43p, respectively. The first wire group 30A is electrically connected to the contacts 42a and 42b. The high-speed signal wires 31a are connected to the contacts 42a, respectively. The low-speed signal wires 31b are connected to the contacts 42b, respectively.
The second wire group 30B is electrically connected to the contact points 43a and 43b. The high-speed signal wires 32a are connected to the contacts 43a, respectively. The low-speed signal wires 32b are electrically connected to the contacts 43b, respectively.

Here, in the second connection member 4, all of the power supply wires 31 p and 32 p are collectively arranged on one side in the left-right direction of the second connection member 4 (right R side in FIG. 2). That is, the first feeder group 30C and the second feeder group 30D have a plurality of electric wires 31p, so as to be adjacent to the first wire group 30A and the second wire group 30B on the top surface 41 of the second connection member 4. It is connected in parallel to one side (right R side) in the parallel direction of 32p.

The first feed line group 30C is connected in parallel to the upper surface 41 of the second connection member 4 so as to be adjacent to the second feed line group 30D. Therefore, the connection between the connection member (the second connection member 4) and the connection target member (the internal member of the electronic device such as the substrate 7) can be facilitated. Further, the first wire group 30A connected to the upper surface 51 of the relay substrate 5 and the second wire group 30B connected to the lower surface 54 of the relay substrate 5 are parallel to one surface 41 of the second connection member 4 Because of the connection, the wires 3 do not get congested. For this reason, connection of the connection members 2, 4 and 5 and the electric wire 3 can be facilitated.

  In addition, since the first feeder group 30C is connected in parallel so as to be adjacent to the second feeder group 30D, power can be easily supplied to the connecting member-equipped multicore cable 1, which is preferable. In addition, since the power supply wires 31p and 32p are arranged together, the power supply wire 31p and the power supply wire 32p do not converge. Therefore, the arrangement of the power supply wires 31p and 32p is facilitated, and the connecting member-equipped multicore cable 1 can be easily manufactured and used.

  Further, since the first wire group 30A and the second wire group 30B are connected in parallel so as to be adjacent to one surface 41 of the second connection member 4, the first wire group 30A and the second wire group 30B Are easy to arrange, and it becomes easy to manufacture the multicore cable 1 with a connection member.

  Further, with the above configuration, the circuit on the substrate or connector to which the first feeder group 30C and the second feeder group 30D are connected is connected to the first wire group 30A and the second wire group 30B (signal lines). Separate from the circuit on the board or connector. For this reason, noise on the first wire group 30A and the second wire group 30B (signal line) can be suppressed, and a signal can be transmitted favorably.

  Further, the front F sides of the plurality of wires 3 and the relay substrate 5 are electrically connected directly. For this reason, arrangement of a plurality of electric wires 3 becomes easy, and manufacture of connecting cable with multi-core cable 1 becomes easy.

The power supply wires 31 p and 32 p may be connected to the right side R side of the first connection member 2 and connected to the left side L side of the second connection member 4.

  Further, in FIG. 3, an example in which two low speed signal wires 31 b and a pair of low speed signal wires 31 b are arranged on the upper surface 51 and the lower surface 54 of the relay substrate 5 has been described. The arrangement of signal lines in is not limited to the example described above. In the first connection member, at least one power supply wire and a plurality of signal wires may be arranged on the upper surface and the lower surface.
