Definitions

• a terminal whose characteristics will depend on the use for which it is destined, can be applied to the end of an electric wire by means of an appropriate system and tool.
• crimping pliers consist of simple pliers, the gripping ends of which are adapted so that they can hold and clamp a terminal with tubular end.
• the main components of the new crimping pliers comprise two handles, two blades, a seat for terminal feeders, a terminal feeding device.
• the two handles are two generically linear elements, hinged at one end and suitable for being grasped like a nutcracker.
• the ends of the two handles that are hinged to each other are shaped so that they permit a limited opening of the two handles and make the grasping of the new pliers comfortable.
• a special elastic element keeps the two handles open, so that they need not be opened manually and the new pliers are always ready for use.
• One of the two handles has U-shaped section, with the concave side facing the opposite handle. The groove formed by the U-shaped section houses the terminal feeder.
• the stripped wire is inserted in the terminal with tubular end positioned in the crimping seat;
• the handles of the new pliers are brought near each other and tightened until the crimping blade correctly deforms the terminal, fastening it to the wire and until the cutting blade has separated the just crimped terminal from the terminal band contained in the feeder; - the handles are released and the wire crimped to the terminal is extracted, leaving the new crimping pliers ready for the following crimping operation.
• the two handles are provided, near their rotation point, with a three- position, lock-release element that prevents, limits or permits the reciprocal rotation of the two handles.
• the lock-release element permits a wide rotation of the two handles from a position in which they are completely close to each other to a wide angular position.
• This position corresponds to the recharge or maintenance position of the new pliers; in fact, in this position it is possible to insert or remove the terminal feeder in/from its U-shaped seat in one of the two handles or, in any case, to reach the crimping seat and the space between the two handles in order to carry out the proper maintenance, cleaning and similar operations.
