3) Disconnections in wiring
If the harness is pulled to disconnect the
connector, or components are lifted with a
crane with the harness still connected, or a
heavy object hits the harness, the crimping of
the connector may separate, or the soldering
may be damaged, or the harness may be
broken.
4) High-pressure water entering connector
The connector is designed to make it difficult
for water to enter (drip-proof structure), but if
high-pressure water is sprayed directly on
the
connector,
connector, depending on the direction of the
water jet.
Accordingly, take care not to spray water
over the connector.
The connector is designed to prevent water
from entering, but at the same time, if water
does enter, it is difficult for it to be drained.
Therefore, if water should get into the
connector, the pins will be short-circuited by
the water, so if any water gets in, immediately
dry the connector or take other appropriate
action before passing electricity through it.
5) Oil or dirt stuck to connector
If oil or grease are stuck to the connector and
an oil film is formed on the mating surface of
the male and female pins, the oil will not let
the electricity pass, so there will be defective
contact. If there is oil or grease stuck to the
connector, wipe it off with a dry cloth or blow
it to dry with compressed air and spray it with
electric contact cleaner.
a When wiping the joint portion of the con-
nector, be careful not to apply excessive
force or deform the pins.
a If there is oil or water in the compressed
air, the contacts will become even dirtier,
so remove the oil and water from the com-
pressed air completely before cleaning
with compressed air.
