Lightening is demanded. For wiring in these electronic information devices, a large number of signal lines are printed or taped as much as possible to reduce the wiring space and to simplify the assembly.

[0003] Connections with circuit components and printed circuits in the machine are usually made via a multi-terminal connector. The multi-terminal connector is provided on both the circuit component and the printed circuit side and the signal line side.For example, when a male connector is provided on the printed circuit side, a female connector is provided on the signal line side, and both connectors are provided.

[0004] A large number of signal lines to be wired inside the device can be reduced in wiring space by bundling the signal lines or arranging them in a line to form a tape. However, a multi-terminal connector requires insulation between terminals and a space between terminals for connection of electric wires, which limits the miniaturization of the connector. Therefore, as long as a wiring member using a connector is used for the internal wiring, there is a limit in reducing the space in the device, and it is difficult to significantly reduce the size of the electronic device itself.

[0006] However, multifunctional electronic information devices,
There is an increasing demand for higher functionality, and it is essential to prevent crosstalk between transmission signals. For this reason, coaxial electric wires having a shield conductor layer in the internal wiring are frequently used. When a coaxial electric wire is wired in a machine via a connector, the electric shield at the connector is easily broken. In the multi-terminal connector using the above-described printed wiring board, although the connector can be reduced in size, it is difficult to form an electrical shield structurally, and a sufficient shield connection cannot be performed.

A large number of connection conductors 3 are punched out from a conductive foil having good conductivity and plated with tin or solder, and are thermally fused to the heat-resistant resin film 4 or 5. The connection conductor 3 is formed in a parallel arrangement pattern corresponding to the arrangement pitch of the contact terminals of the mating connector to be connected. In order to obtain a good electrical connection with the contact terminal of the mating connector, the conductor width of the connection conductor 3 should be as large as possible.
