Mounting and fixing of connectors
The connector is an important electrical component on the wiring harness assembly. When designing the wiring harness layout, attention should be paid to the installation and fixation of the connector. There are mainly the following requirements:
The wire harness at the end of the connector needs to reserve a certain length to facilitate the insertion and removal of the connector.
Regarding the reserved length of the connectors, the focus is on the connectors of the instrument panel, switch panel, air conditioner panel, audio system and display screen connected to the wiring harness of the instrument panel, the wiring harness of the four-door switch, and the ceiling light on the indoor ceiling And switch wiring harness, in addition, the wiring harness plug-in on the sub-instrument, the wiring harness plug-in under the seat and the wiring harness and wiring harness docking plug-in also need to be reserved for length.
According to the installation depth of the electrical device, the position of the socket, the opening direction of the socket and the rear space after the electrical device is assembled, according to the convenience of operation, appropriately increase the reserved length of the connector on the wiring harness.
Reserved length L = electrical installation depth h + electrical installation panel width 0.7B + 100 (mm),
Among them: the installation depth of the electrical device h—refers to the distance from the external decorative surface to the connecting socket of the internal electrical device after the electrical device is assembled; the panel width of the electrical device 0.7B- refers to 0.7 times the height of the front decorative surface of the electrical device.
When making length reservations, special attention should be paid to the abnormal noise and cutting of the wiring harness. The damage of the wiring harness can be avoided by adding an anti-cut wrapping outside the wiring harness, adding an anti-cutting tape to the surrounding sharp parts, etc., and reducing abnormal noise by wrapping the sponge.
