5-2. Stripping of wire outer insulation
(1) Correct stripping length
Stripping length of the wire is specied for each contact. Correct crimping depends on accurate stripping of the
wire.
Correct stripping length: After crimping the conductors should protrude from the top end of the Wire barrel and the
Insulation barrel should be around the Outer insulation, as shown on the illustration on the left. Before crimping do
not pull on the outer insulation or attempt to insert it in the Wire barrel.
(2) Stripped wire condition
Bellmouth must be present at the rear of the conductor crimped section and must be within the specified
dimensions.
Size of it varies with each contact style. Absence of the bellmouth may cause conductor breakage and will a󰀨ect
the tensile strength of the crimp. Excessive bellmouth may indicate insu󰀩cient tensile strength of the crimped
section of the contact and a󰀨ect the electric connection.

the contact. Some kind of terminal has front bellmouth but only rear bellmouth needs to be checked.
󰴤
Conductor should be free from any damage or partially broken or missing strands.
󰴥
The conductor and outer insulation cut-o󰀨’s must be straight. The outer insulation can not be loose.
5-2. 电线被覆的剥皮
(1) 剥皮长度是否合适
电线的剥皮长度是根据每个端子设定的。由于压接的操作质量会受到剥皮长度加工精度的影响，因此，请多加
注意。
合适的剥皮长度：在压接时，芯线从钢线筒顶端突出，此外，被覆没有从绝缘筒拉入，或没有进入屏蔽筒的状态。
(2) 电线剥皮状态
󰴤
芯线没有损伤。此外，部分没有断线或脱落。
󰴥
芯线的长度、被覆切断端面没有错位或不整齐。
5-3. 钟罩
5-4. Crimp height
Crimp height is critical factor in determining the correct crimp condition and must be as specied.
Specied wire size, construction and style must be used. The crimp height requirement may not be applicable
with some wires although they may be within the specied dimensions.
* Use the micrometer for measuring the crimp height.
关于进行了压接的端子，请确认后部是否存在钟罩。
关于钟罩的大小，根据端子而有变化。如果没有钟罩，有可能造成钢线筒端面的芯线断裂，或造成压接部分拉伸强
度不足。如果钟罩过大，有可能造成电气性连接不稳定，或压接部分拉伸强度不足。
( 注意 ) 有些端子上有前部的钟罩，如果后部的钟罩符合“各个端子的压接质量基准书”的标准，则没有问题。
5-4. 压接高度
压接高度是决定压接端子压接质量的重要原因。
如果压接高度不符合标准，有可能造成质量上的重大事故。如果是手动压接工具，即便是在端子的合规电线范
围内，有时用于工具的电线不合规，请注意。
* 关于压接高度的测定，请使用压接高度测定用千分尺。
