Description

  The present invention relates to a wire harness disposed in an automobile, a motorcycle such as a motorcycle, an electric appliance, and the like, and when the wire harness is disposed, the periphery of the wire harness is prevented from interfering with a peripheral component (target component) in the disposed portion. The present invention relates to an interference examination system for examining a gap interval between parts. More specifically, the present invention relates to an interference examination system between a wire harness and peripheral components that can be examined by adding interference requirements with various types of peripheral components for the types of protective materials (including strands) covering the wire harness.

  The wire harness is a bundle of electric wires that supply electricity to automobile equipment, electrical equipment, and the like. In the case of a car, it is said that it is stretched around every part of the car and plays the role of blood vessels and nerves in humans. When the wire harness is disposed, various types of protective materials that cover the wire harness are set when the wire harness is a bare wire. Then, before the wire harness is actually installed, the gap measurement system measures the gap between one part and another part. In the case of a wire harness, the gap between the wire harness and its peripheral parts (target parts) is measured. Displays whether the design is OK or NG. The interference requirements used in these gap measurement systems are already in a database.

  The conventional general-purpose gap measurement system only measures the gap distance between a part and a part, and therefore, the requirements regarding the gap interference peculiar to the wire harness have not been considered at all. In other words, the requirements regarding the interference between the wire harness and its peripheral parts are based on the type of protective material (the strands that cover the wire harness) due to the unique property that the wire harness may vibrate between multiple restraints. Included) and the type of the peripheral component to be targeted. Therefore, the determination of whether or not a wire harness of one requirement (type of protective material) actually interferes with a certain type of peripheral component differs depending on the combination of the type of wire harness and the type of peripheral component. There is a case.

  As shown in the flowchart of FIG. 5, the conventional general-purpose gap measurement system inputs (B) evaluation conditions after (A) evaluation starts. The evaluation condition is a gap requirement in a database of a certain part (10) and a certain part (11). In this conventional example, the peripheral component (11) is RF (reinforce) (C6), and the component (12) is the wire harness WH. In the case illustrated in FIG. 7, the wire harness WH is connected to the corrugated type wire harness WH3 and the protective material is a sheet type wire harness WH5, and the protective material is around the corrugated type wire harness WH3. RF (C6), which is a peripheral component, is provided. In this case, as shown in FIG. 6 by the numerical value of the gap measurement system database already created in the database, the interference requirement (gap requirement) is the RF (C6) and the component (11) which are the peripheral components (10). An interval with a certain wire harness WH3 is set to 10 mm or more from the database.

  (C) Next, the gap between the RF of the peripheral component (10) and the wire harness WH3 (11) in which the protective material is the corrugated type is actually measured and evaluated (see FIG. 7). (D) The result of this evaluation is displayed, and (E) the evaluation ends.

  However, as shown in FIG. 6, when the actual measurement of the distance between the RF of the peripheral part (10) and the protective material of the part (11) between the corrugated type wire harness WH3 is 5 mm, the conventional gap measurement In the evaluation of the system, NG occurs because the gap interval is set to 10 mm or more. However, as an actual requirement, when the RF of the peripheral component (10) and the protective material of the component (11) are the corrugated type wire harness WH3, the interference is OK in the numerical values in the gap interference requirement database. Therefore, it becomes a misjudgment. That is, in the conventional gap measurement system, an erroneous determination of the gap measurement evaluation is likely to occur, and in the case of an incorrect determination, there is a risk that the cost of the vehicle will rise, such as setting an expensive protective material. Therefore, there is a problem that the number of steps for reconfirmation increases.

In order to solve the above problems, in a wire harness covered with a wire or a protective material disposed in an automobile device, an electrical device, etc.,

In addition, for wire harnesses covered with strands or protective materials arranged in automobile equipment, electrical equipment, etc.
Use a personal computer that has a control unit, a data input unit, and a display unit.
Determine the type of wire harness classified according to the type of wire or protective material actually installed and input it to the personal computer from the data input unit,

Corresponding to the type of wire harness classified according to the type of element wire and protective material, the gap interference requirement is a database of gap interference requirement data for each type of peripheral component in the place where the wire harness and the wire harness are installed. We propose a system for examining interference between a wire harness and peripheral parts, characterized in that an evaluation result obtained by comparing with a numerical value in a database is displayed on a display unit.

  According to the present invention, when the wire harness is disposed, the clearance (interference requirement) between the wire harness that is preliminarily determined at the time of designing or the wire harness covered with several kinds of protective materials and the peripheral component (target component) is set. ), The number of erroneous judgments is greatly reduced compared to the conventional case, the number of man-hours for reexamination due to an evaluation error can be reduced, and the working efficiency is improved. Furthermore, since the expensive protective material due to misjudgment is not used, the possibility of the vehicle cost rising can be greatly reduced.

The comparison table includes (WH1 to WH5) for each type of wire harness WH classified according to the type of protective material covering the wire harness including the wire WH1 of only the wire harness on the vertical axis, and each wire on the horizontal axis. The peripheral parts (C1-C6) corresponding to the type of harness WH are taken.

  According to FIG. 3, for example, when the peripheral part of the portion where the wire harness WH1 is disposed is a hose C5, the gap interval is less than 20 mm, and the portion where the wire harness WH4 whose protective material is a sheet is disposed When the peripheral part is spot C4, the gap interval is 0 mm or more.
