Embodiment Construction

[0025] figure 1 A schematic diagram of the wiring test device 1 according to the embodiment is shown. The test device 1 is shown connected to a partially assembled wiring harness 9 comprising a connector housing 3 and a plurality of electrical wires 5 . In this illustrative example, the wire harness 9 is shown as a sleeve-type wire harness, the proximal ends of the wires 5 are connected to respective terminal pins 4 within the terminal array of the connector housing 3 and the distal ends of the wires 5 are free floating. However, it will be appreciated that one or more of these wires 5 may be terminated with a plug or other connector.

[0026] The connector housing 3 is connected into a corresponding socket provided on the transmitter 2 . The socket comprises a plurality of female port terminals which accommodate the male terminal pins 4 of the connector housing 3 when the connector housing 3 is fitted into the socket. This thus establishes an electrical connection between ...

Abstract

The invention relates to a wire harness test device and method for verifying connections when assembling a wire harness. A device (1) for verifying wiring connections during the assembly of a wire harness (9) is provided. The wire harness (9) comprises a connector (3) having an array of terminals (4) and a plurality wires (5) connected to individual ones of the terminals (4). The device comprises a transmitter (2) for applying different signals to different terminals (4) for emitting a corresponding electromagnetic signal from a wire (5) connected to that terminal. Each electromagnetic signal has an associated identifying characteristic. A detector (6) is used to receive the electromagnetic signals emitted from the wires (5) connected to terminals (4), and a processor (7) generates an output which is used to identify the received electromagnetic signals based on their detected identifying characteristics. A method of assembling a wire harness (9) using the device (1) is also disclosed.

Description

technical field [0001] The present disclosure relates to a wire harness testing apparatus and method for verifying connections when assembling a wire harness. Specifically, the present disclosure relates to a test device for verifying connections when assembling a wire harness and a method of using the test device. The present disclosure is particularly suitable for the assembly of wire harnesses for the automotive and aerospace fields. Background technique [0002] Wire harnesses (also known as cable harnesses and wiring assemblies or wiring looms) are used to connect electrical components within automobiles and airplanes, as well as other vehicles and construction machinery. By bundling large numbers of wires together into bundles, wiring can be installed into vehicles more quickly and reliably. However, despite increased automation, wiring harnesses are still typically assembled by hand. The wiring harness is therefore usually one of the most expensive parts of a vehic...
