When a crimping tool is used on a terminal, two crimps take place at the same time. One is the electrical connection between conductor and terminal. The other is the insulation crimp which provides strain relief against vibration and tension. It is important that the electrical connection is gas tight without any voids between the wire strands and the terminal. If there any voids present, then corrosion can occur causing resistance and excessive heat which damages the electrical connection. Using a good quality crimping tool will ensure that a full, gas tight crimp is produced preventing future deterioration of the electrical connection and insulation breakage
From TE Connectivity an ERGOCRIMP commercial grade hand operated crimping tool frame assembly designed to accept a wide range of interchangeable SDE die assemblies. Commercial grade hand crimping tools incorporate features for long lasting performance including a construction of durable high-carbon steel and extra strength pivot pins. The head of the crimping tool is angled to reduce hand-stretch and to allow an easier view of the crimp area. The handles have a reduced handle force and an ergonomic design reducing operator fatigue and making the tool easy and comfortable to use.
The tool frame has two handles and jaws (stationary and moving) and an adjustable ratchet with emergency ratchet release. The jaws of the tool frame are slotted for easy insertion of the die assemblies which are secured in place by two screws.
