The overlapping portion is in a state of being brought down and arranged along the cylindrical portion.
Abstract:
In a calculating apparatus for calculating a predictive shape of a wire structure using a finite element model, a predictive shape of the finite element model which is in a physically balanced condition based on physical properties and restriction conditions is calculated. When it is determined that the predictive shape of the finite element model crosses an obstacle model, the control point of the finite element model is returned to a position corresponding to a position immediately before the crossing of the joint with the obstacle model and a crossing joint which is the joint crossing with the obstacle model is bound to a contact point of the finite element model with the obstacle model. The predictive shape is output when the control point is returned to a position at the time of crossing of the finite element model with the obstacle while maintaining the binding.
Abstract:
The invention relates to a method and apparatus for preventing water from penetrating into a wire harness, the wire harness containing a plurality of electrical wires and being adapted to fit into a grommet and to pass through a hole formed in a vehicle panel. The electrical wires respectively include a section which is to form part of a water-sealed portion. The electrical wires are arranged so that the sections forming part of the water-sealing portion are in parallel in a row. A first water-sealing agent is applied on the sections. A second water-sealing agent is applied over the first water-sealing agent, the second water-sealing agent having a viscosity higher than that of the first water-sealing agent. The parallel arrangement of sections are curled for fitting into the grommet, so as to form the water-sealed portion.

Abstract:
A calculation method for packing a plurality of wires constituting a wire harness comprises the steps of: removing a first circle from a plurality of circles; forming a primary inclusive circle as small as possible in which a plurality of second circles are included in the primary inclusive circle so as not to be overlapped with each other; calculating first position information regarding a position of the primary inclusive circle and the second circles included in the primary inclusive circle; forming a final inclusive circle as small as possible in which the first circle is arranged in the primary inclusive circle while the second circles are fixed in the primary inclusive circle in accordance with the position information such that the first circle and the second circles are not overlapped with each other; calculating and outputting second position information regarding a position of the final inclusive circle.
Abstract:
In a system for preparing a wire harness production, a modified wiring pattern generator generates modified wire harness wiring pattern information related to at least one second pattern in which at least one of parts, electric circuits, and wirings of a first pattern including the parts, the electric circuits, and the wirings of a standard type vehicle is altered. A parts information storage stores parts specification information including specifications of the parts, the electric circuits and the wiring included in the second patterns. A simulator simulates whether each of the second patterns is practical while referring to the parts specification information. A sub wiring pattern modifier modifies at least one of first sub patterns constituting the first pattern to at least one of second sub patterns so as to constitute the second pattern judged as practical by the simulator. A jig arrangement pattern information generator generates jig arrangement pattern information related to jig arrangement patterns prepared by applying at least one sub jig arrangement pattern to each of a plurality of wire harness path patterns of the standard type vehicle included in wire harness path pattern information. Path decision information selects one wire harness path pattern among the plurality of wire harness path patterns. Alternation information indicates at least one of alternation portions altered from the first pattern. A jig arrangement pattern selector selects one jig arrangement pattern corresponding to the selected wire harness path pattern among the plurality of wire harness path patterns. A path plan generator generates a path plan by integrating the modified second sub pattern having the alternation portions which is indicated in the alternation information and the selected jig arrangement pattern.
Abstract:
A plurality of insulator-sheathed electric wire elements (a) are secured together to a connector (C) by an insulation displacement manner by means of juxtaposing the electric wire elements (a) on a plane, passing the wire elements (a) through a gripper (10), an insulation displacement press (30), clamping the passed ends of the wire elements by a chuck (43) of a measuring and drawing device (40), drawing the juxtaposed wire elements (a) by a given length by the chuck (43), and pressing the juxtaposed wire elements (a) at the given position in the length and width directions. The connector (C) is attached to the juxtaposed wire elements (a) at the position in the length and width directions by repeating the steps. Upon pressing, the given electric wire elements are cut off at the rear side of the pressed portions. The gripper (10) clamp the juxtaposed wire elements (a) after cutting them. The cut ends of the juxtaposed wire elements (a) are displaced to the chuck (43) in the measuring and drawing (40) and then are clamped by the chuck (43). The wire harness (W) can be produced by repeating the steps.
Abstract:
A wire harness distributing method in which a wire harness is easily distributed with the aid of a trimming plate which is mounted to a wall surface such as a vehicle body panel, and once the trimming plate is mounted, even if the trimming plate is removed, all or part of the wire harness remains on the wall surface for easy maintenance. The method of distributing a wire harness with connectors to a wall surface such as a vehicle body panel includes the steps of: providing a first preliminary locking member for a wire harness on a trimming plate which is to be mounted to a wall surface; providing a second preliminary locking member to the wire harness, and detachably and preliminarily locking the wire harness to the trimming plate; and fixing the trimming plate and the wire harness to the wall surface.

An assembly device for a wiring harness comprises a fork (11) having legs (12,13) and a closure (17). One of the legs (12) is rigid, and the other leg (13) and the closure (17) are relatively flexible to permit wires to enter the fork with ease and to permit the completed harness to be extracted with ease. A second embodiment has two rigid legs (12a,12b).
Abstract:
A method of effectively manufacturing various types of wire harnesses of complicated wiring structure in which a predetermined number of connectors necessary for a unit wire harness are arranged on a movable pallet. The pallet is then moved so that crimp-style terminal of one of the connectors can come to a crimp connecting position of a rotatable crimp connecting press. An end of an electric wire is fed to the crimp-style terminal at the crimp connecting position. The end of the electric wire is then connected to the terminal by the rotatable crimp connecting press. Then, the pallet is moved again, and the other end of the electric wire is connected to a crimp-style terminal of a predetermined connector by crimp connection. The series of motions are repeated until all terminals necessary for the unit wire harness are connected to the electric wires by crimp connection. According to this method, a rotatable crimp connecting press has a plurality of different crimp connecting blades.
