Crimping tool
6. Examples of Improper Crimping
Item
1. Incorrect crimp height at the
wire barrel section
2. Improper crimping of the
insulation
3. Deformation on the contact
3.1 Deflection
3.2 Twisting
3.3 Deformation of the barrel
4. Improper crimping
4.1 Incomplete
insertion
4.2 Insertion of
covered wire
4.3 Conductor forced
out of the wire barrel
4.4 Overstripping
5. Dispersion of the crimp
heights.
6. Abnormal state of the
crimping tool.
Note: When the above improper crimping occurs, contact a sales person or the Engineering Department.
Condition
The crimp height measured according to the
diagram of crimp height measurement
indicates the value outside the standard range.
There is a space between the outside
diameter of the insulation and barrel,
and the wire is not secured in position.
Abnormal shape
of the barrel,
burr, etc.
A
The crimping position of the tool is
unstable.
The ratchet cannot be released even if
the handle is completely closed.
Others
Cause
Abrasion or looseness in the tool
(The crimping tool must be properly adjusted.),
or use of an non-standard wire.
Abrasion or looseness in the tool, or
use of a non-standard wire.
> 3˚
Chip, abrasion or deformation of the
knife edge (crimper and anvil)
> 3˚
The conductor is not completely inser-
ted into the wire barrel.
The length of the stripped wire is short-
er than the standard length. Or, the
wire covering is digging into the wire
barrel because too long a wire has
been inserted.
The conductor is being forced out of
the wire barrel.
The covered part of the wire is crimped
only on one side because the stripped
part is longer than the standard lenght.
The covered part of the wire has the
standard length, however, the dimen-
sions A is 1.5mm or more.
Even if the handle is not completely
closed the ratchet releases because of
abrasion and deformation.
The ratchet is deformed or several
springs are broken.
