The crimping pliers include pre insulated end crimping pliers, tubular end crimping pliers, bare end crimping pliers, screw driver split action, electric, pneumatic, and can be divided into cross, word.
Conductor precautions: < br > 2 The signal line should be shielded double core conductor as far as possible Select insulated conductor without interference (cost saving); < br > 0 Tinned copper conductor shall be used for equipment with humid environment or with "th" words When there is no requirement, the cross-sectional area of the conductor shall not be less than 0.5 square mm (to ensure safety); < br > the Under normal circumstances, the conductor is black; the DC power line is brown positive blue negative, the neutral line is light blue, and the yellow green is the grounding wire (heavy color); < br > Precautions for thread pressing: < br > 1 After crimping, the connector should not be bent Test: the pressed thread can not be pulled out with normal force; < br > conclusion: the pressed thread can not be pulled out with normal force The indentation of the bare end must be in the center of the crimping pipe and on the pipe seam; < br > the indentation of the bare end must be in the center of the pressure pipe and on the pipe seam When the conductor core is inserted into the end, it is not allowed to break the wire or expose the wire core to the outside;
