Matters needing attention

(The outer sheath of the wire harness must not be broken, otherwise it must be wrapped and fastened with tape or cable ties after wrapping the bellows).

(At the same time, the connectors of various wiring harnesses should be placed near the access port convenient for maintenance personnel when the wiring harnesses are tied and fixed).

一、Top frame harness

Process content:

Note:

Technological parameter:

  1. The wiring harness at the plug-in should have an active margin (30 ~ 50)mm
  2. Both ends (30 to 50 mm) of the insert must have fixed points.
  3. The spacing of two fixed points on the baggage support is (300 ~ 400)mm, and the spacing of other fixed points is not more than 700mm.
  4. The sag of wiring harness is not less than 10mm.

Quality requirements:

  1. When wiring harness is connected with electrical appliances, a certain margin should be left;
  2. The insertion body should not be stressed, and should not be pulled too tight or too loose.
  3. The distance between fixed points of the wiring harness is appropriate.
  4. The top frame harness is not allowed to walk inside the heat insulation board!
  5. When the cable card is fixed, roll up the winding bundle of the cable card and push the bracket with your hand to ensure that there is no relative movement between the cable bundle and the cable card, rather than simply bending the cable card up. The clamp should be properly flattened so that the harness and it have no displacement, and should not sag significantly.
  6. The wiring harness shall be flat and straight, not lower than the lower plane of the profile, and the excess growing wiring harness shall be folded neatly and fixed firmly.
  7. There should be no interference friction between the top wind window wiring harness and the moving parts of the top wind window pushing rod, the spacing should be at least (30~50)mm, and there should be enough activity margin (according to the amount of activity of the top wind window pushing rod in the two states of the switch), the wire harness should not be load-bearing and the wire harness should not be squeezed when pushing and pulling.
  8. Channel lights, horns, door lights, driver lights, reading lights, decorative lights, height lights and other electrical products can not be squeezed wire harness during installation, especially for the need to open holes in the field is strictly prohibited to damage the wire harness.

Quality requirements:

The ground cable of the air conditioner should be firmly fixed with flat washers and spring washers.

二、Instrument main wire harness

 

Process content:

Technological parameter:

Quality requirements:

  1. The distance between fixed points of the wiring harness is appropriate. The wiring harness should be arranged neatly. A maintenance allowance of at least 150mm should be left in the length of the wiring harness, and the reserved branch wiring harness should be stacked neatly and tied securely with cable ties.
  2. When fixing the wiring harness, it is necessary to consider that the damage of the wiring harness should not be squeezed when installing the instrument panel and other components, and the operation of opening holes and nailing should be considered to protect the wiring harness so that it can not be damaged.
