00 Index and foreword
Foreword, safety and general information
Handling of electrical equipment (Rev. 2012/11)
• To maintain the performance of the machine over a long period, and to prevent failures or troubles before they occur, correct "operation", "maintenance and inspection" "troubleshooting", and "repairs" must be performed. This section deals particularly with correct repair procedures for mechatronics components and is aimed at improving the quality of repairs. For this purpose, it describes the working procedures in "Handling of electrical equipment".
Precautions for handling electric equipment
Handling wiring harnesses and connectors
• Wiring harnesses consist of wires connecting one component to another component, connectors used for connecting and disconnecting one wire from another wire, and protectors or tubes used for protecting the wires.
• Compared with other electrical components fitted in boxes or cases, wiring harnesses are more likely to be affected by the direct effects of rain water, heat, or vibration. Furthermore, during inspection and repair operations, they are frequently removed and installed again, so they are likely to suffer deformation or damage. For this reason, it is necessary to be extremely careful when handling the wiring harnesses.
Main failures occurring in wiring harness
Defective contact of connectors (defective contact between male and female connectors)
• Problems with defective contact are likely to occur because the male connector is not properly inserted into the female connector,or because one or both of connectors are deformed or the position is not correctly aligned, or because there is corrosion or oxidization of the contact surfaces. The corroded or oxidized contact surfaces may become shiny again (and contact may become normal) by connecting and disconnecting the connectors approximately 10 times.
Defective crimping or soldering of connectors
• The pins of the male and female connectors are attached to wires by crimping or soldering. If excessive force is applied to the wire, the joining area may become loose, which may result in a defective connection or breakage.
Disconnections in wiring
• If the wiring harness is pulled to disconnect the connector, or the components are lifted with a crane while the wiring harness is still connected, or a heavy object hits the wiring harness, the crimping of the connector may separate, or the soldering may be damaged, or the wiring harness may be broken.
