A method of preparing a wire harness production by providing standard wiring pattern information related to a first pattern including parts, electric circuits and wirings of a standard type vehicle, and generating modified wiring pattern information related to at least another pattern in which at least one of the parts, the electric circuits, and the wirings of a first pattern is altered.

Method of preparing a wire harness production

It is an objective of the present invention to provide a wiring harness fixing device, by which a wiring harness can be easily removed from a panel of a motor vehicle and the saving of resources can be attained. A wiring clip as the wiring harness fixing device fixes a wiring harness on a panel. The wiring clip includes a mount and an engaging part. The mount has a flat plate-shape. The engaging part includes a standing piece standing up from the mount, a pair of engaging pieces, a thin part, and a thick part. The pair of engaging pieces has a mountain-shape, in which one end thereof continues to an end of the standing piece. The thin part is formed concave from an outer surface of the standing piece and has the minimum cross-sectional area in the standing piece. The thick part protrudes from the outer surface of the standing piece. The thin part is situated nearer to the mount than the thick part is situated near the mount.

Fixing device for wire harness

A metal terminal has a terminal body having a crimp part crimped to a wire and a fastening part connected to the terminal body through breaking parts. The fastening part has a through-hole for passage of a bolt. The metal terminal further includes a co-fastening part formed in the terminal body. The tip side of the co-fastening part is fastened to a vehicle body by the bolt, together with the fastening part. When detaching the terminal body from the vehicle body, one side of the one terminal body is pulled up in a direction opposite to the fastening direction of the bolt under condition that the fastening part and the co-fastening part are together fastened by the bolt. Consequently, the co-fastening part is released from its fastened condition and a breaking force is applied on the breaking parts.

In preparing a wire harness production, modified wire harness wiring pattern information is generated. The generated information relates to second patterns, in which some parts of a first pattern are altered. Each of the second patterns is simulated for practicality. Where practical, according to the simulation, a first sub-pattern is modified to one of the second sub-patterns to achieve the desired second pattern. Jig arrangement pattern information is generated by applying at least one sub jig arrangement pattern to each of the wire harness path patterns of a standard type vehicle included in wire harness path pattern information. Path decision information is used to select one wire harness path pattern. A jig arrangement pattern selector selects a jig arrangement pattern. A path plan is generated by integrating the modified second sub pattern having the necessary alterations and the selected jig arrangement pattern.

System for preparing wire harness production

A grommet includes a corniced part in a shape of a bellows, and two engaging parts integrally formed on opposite ends of the corniced part and adapted to be engaged with respective bodies to be fitted such as a chassis panel and a door panel . The grommet is formed in a hollow tubular shape in such a manner that the corniced part is smaller in diameter than the engaging parts . The grommet can be obtained by molding thermoplastic elastomer by injection molding so that the diameter of the engaging parts is less than five times as large as the diameter of the corniced part, opening molds for forming an outer face thereof, and thereafter, enlarging the corniced part thereby removing the grommet from a core for forming an inner face thereof.

Grommet and method of producing the same

A grommet includes a first cylindrical portion for passing a wire harness therethrough, a second cylindrical portion for fitting in a mounting hole in a panel , and a connecting portion interconnecting the first and second cylindrical portions and . The second cylindrical portion is turned inside out, and flange portions , formed on the second cylindrical portion , are passed through the mounting hole . Subsequently, the second cylindrical portion is restored into its initial shape by its own restoring force, thereby mounting the grommet in a predetermined position. Ribs are formed on an inner peripheral surface of the connecting portion , and the position of folding of the connecting portion is determined by these ribs, thereby preventing the grommet from being excessively reversed, and by doing so, the restoration of the grommet into its initial shape can be easily started.

Grommet

In order to insert a wiring harness and to retain it in a mounting hole in a body panel a grommet is so designed that a first cylinder and a second cylinder are connected together via a connector and that a plurality of flanges and guide portions are radially formed. For the grommet when the second cylinder is everted, the flanges are closely attached to the outer face of the first cylinder and are inserted into the mounting hole and do not interfere with the guide portions Then, when reversion of the second cylinder is effected, a groove is fitted into the mounting hole.

A fusible link mounting method in which a fusible link is mounted onto a fusible link housing, and a leg portion of the fusible link and a terminal of an electric wire are tightened and connected together by a bolt. In the method, the bolt is previously tightened provisionally with respect to the fusible link housing, after then, the terminal including a bridge portion so formed as to be able to pass outside a head portion of the bolt provisionally tightened is slid and inserted in a direction right angles to the bolt tightening direction in a separate step to thereby position a connecting portion of the terminal between the head portion of the bolt and the leg portion of the fusible link, and, next, the bolt is actually tightened to thereby connect the leg portion of the fusible link and the connecting portion of the terminal to each other.
