Abstract

A device for determining an electrical wire bundle, in which, when the electrical wire bundle includes even one test electrical wire which conducts electricity to a terminal device, the electrical wire bundle is given an A-rating indicating an electrical wire bundle to be used for a test; when the electrical wire bundle includes at least one electrical wire which conducts electricity to the terminal device but is not the test electrical wire, the electrical wire bundle is given a B-rating indicating that the electrical wire bundle is not allowed to be disconnected; and when the electrical wire bundle includes only electrical wires that do not conduct electricity to the terminal device, the electrical wire bundle is given a C-rating indicating an electrical wire bundle not to be used for the test.

Claims

1. A device for determining an electrical wire bundle which determines which electrical wire bundle includes a test electrical wire to be used for an electrical test in a wiring structure interconnecting terminal devices through a plurality of wire harnesses each including a plurality of electrical wires composing an electrical wire bundle and connectors connected with the electrical wires, the device comprising:

a storage unit which stores connection information about connection relations between the electrical wires and the connectors; and

a processing unit which determines which electrical wire bundle includes the test electrical wire on the basis of the connection information stored in the storage unit, wherein,

when the electrical wire bundle includes even one test electrical wire which conducts electricity to the terminal device, the processing unit gives the electrical wire bundle an A-rating which indicates an electrical wire bundle to be used for the test, and

when the electrical wire bundle includes only the electrical wires that do not conduct electricity to the terminal device, the processing unit gives the electrical wire bundle a C-rating which indicates an electrical wire bundle not to be used for the test.

2. The device for determining an electrical wire bundle according to claim 1, wherein, when the electrical wire bundle includes at least one electrical wire which conducts electricity to the terminal device but is not the test electrical wire, the processing unit gives the electrical wire bundle a B-rating which indicates that the electrical wire bundle is not allowed to be disconnected.

3. The device for determining an electrical wire bundle according to claim 1, wherein

on the basis of identification information on pins of a test connector included in the terminal device used for the test, the processing unit links pieces of the connection information stored in the storage unit to one another, and gives each of the linked electrical wires a category a which indicates that the electrical wire is the test electrical wire, and

when the electrical wire bundle includes even one test electrical wire to which the category a is given, the processing unit gives the electrical wire bundle the A-rating.

4. The device for determining an electrical wire bundle according to claim 2, wherein

on the basis of identification information on pins of a test connector included in the terminal device used for the test, the processing unit links pieces of the connection information stored in the storage unit to one another, and gives each of the linked electrical wires a category a which indicates that the electrical wire is the test electrical wire, and

when the electrical wire bundle includes even one test electrical wire to which the category a is given, the processing unit gives the electrical wire bundle the A-rating.

5. The device for determining an electrical wire bundle according to claim 3, wherein

on the basis of identification information on pins which are pins of a connector mated with the terminal device used for the test and other than the pins of the test connector, the processing unit links pieces of the connection information stored in the storage unit to one another, and gives each of the linked electrical wires a category b which indicates that the electrical wire conducts electricity to the terminal device but is not the test electrical wire, and

when the electrical wire bundle includes no electrical wires to which the category a is given but includes the electrical wire to which the category b is given, the processing unit gives the electrical wire bundle the B-rating.

6. The device for determining an electrical wire bundle according to claim 4, wherein

on the basis of identification information on pins which are pins of a connector mated with the terminal device used for the test and other than the pins of the test connector, the processing unit links pieces of the connection information stored in the storage unit to one another, and gives each of the linked electrical wires a category b which indicates that the electrical wire conducts electricity to the terminal device but is not the test electrical wire, and

when the electrical wire bundle includes no electrical wires to which the category a is given but includes the electrical wire to which the category b is given, the processing unit gives the electrical wire bundle the B-rating.

7. The device for determining an electrical wire bundle according to claim 5, wherein

the processing unit temporarily gives a category c, which indicates that the electrical wire or the connector does not conduct electricity to the terminal device, to all the electrical wires and connectors included in the connection information, and

for the electrical wires to which the category a or the category b is given, the processing unit changes the category c to the category a or the category b, and gives the C-rating to the electrical wire bundle which includes only the electrical wires of the unchanged category c.

8. The device for determining an electrical wire bundle according to claim 6, wherein

the processing unit temporarily gives a category c, which indicates that the electrical wire or the connector does not conduct electricity to the terminal device, to all the electrical wires and connectors included in the connection information, and

for the electrical wires to which the category a or the category b is given, the processing unit changes the category c to the category a or the category b, and gives the C-rating to the electrical wire bundle which includes only the electrical wires of the unchanged category c.

9.
