The present invention discloses a tape binding device winding a tape piece having an adhesive surface on one side around an electric wire bundle to bundle it. In the device, a pair of arms having a holding surface are lowered while holding the tape piece cut into a predetermined length on the holding surface. As it is lowered, free ends of both arms are lowered to both sides separated by a top portion of the electric wire bundle. At the time of lowering, after winding the tape piece by pressing it around a surface of the electric wire bundle, the free ends of both arms make adhesive surfaces of both ends of the tape piece under the electric wire bundle to adhere each other and are clipped between them, thereby laminating adhesive surfaces each other.

A wire laying-out apparatus automatically lays out an electric wire on a wire laying-out plate. The electric wire is laid out by a wire laying-out head which is freely moved on the wire laying-out plate by an X-direction feed shaft and a Y-direction feed shaft. A plurality of wire guiding devices are arranged in a linear manner on the wire laying-out head. A selecting device is provided in the vicinity of the wire guiding device. The selecting device selects one of the wire guiding devices. It is possible to lay out the electric wire by lowering a wire guiding device. When the electric wire to be laid out is replaced, the electric wires are not tangled. An oblique arch including guide rollers for guiding the electric wires to the wire guiding devices helps inhibit tangling of the wires. In addition, the wire guiding devices are integrated with the wire laying-out head so that the electric wire can be replaced irrespective of the position on the wire laying-out head. Therefore, it takes less time to replace the electric wire.

The invention relates to a mechanism for inserting wired terminals into connector housings and includes a terminal moving part for detaching the front end part of the wires from a clamping part and moving the terminals adapted to inwardly return to a lay-out board, a housing holding part for holding a connector housing so that the terminal insertion ports in the connector housing confront the terminals returned to the lay-out board, and a terminal inserting part for inserting the terminals into the terminal insertion ports by bringing the connector housing and the terminals, which terminals are opposite to the terminal insertion ports of the connector housing, closer at the terminal insertion movable region.

The fabrication of wiring harnesses requires many steps, such as a wire laying out step of laying out electric wires coated with insulative sheaths in a laying out array and cutting with measured length, a stripping step of the insulative sheaths at the ends of the electric wires, a crimping step of pressing terminals together with the bared ends of the electric wires in crimp contact, an inserting step of inserting into connectors the terminals pressed in crimp contact, etc. This system has an apparatus for each step modularized, and a module incorporated in the system can be increased or decreased in number depending upon a type of the desired wiring harness. For example, it is assumed now that a wiring harness fabrication line consists of an automated wire laying out module (1), a stripping module (3), two terminal-crimping modules (5), and a terminal-inserting module (7). When the type of the desired wiring harness is changed, additional automated wire laying out module (1) and terminal-inserting module (7) are provided in this fabrication line, and eventually, there can be incorporated two of the automated wire laying out modules (1) and two of the terminal-inserting modules (7) in this fabrication line. Thus, the automated fabricating system according to the present invention is a system pliably adjustable to the change of a design of the wiring harness.
