Aspects of the present invention relate to an apparatus for holding at least one elongated workpiece to be crimped, and to a crimping tool comprising such an apparatus.
Cable termination tooling, e.g. hand-operated or machine-operated tools, may comprise cutting tools, stripping tools and crimping tools. Some tools have only one of the above-mentioned functions, whereas other tools have two or three of the above-mentioned functions. Cable termination is required e.g. for connecting a cable or a wire to power, coaxial, fibre-optic or modular connectors.
When crimping, a terminal, i.e. a connector, a ferrule, a contact or a similar device, is mechanically secured to a cable, e.g. to a conductor such as a wire, by deformation so that a solid joint having reliable mechanical and/or electrical connection is formed. The crimping operation resulting in a crimped joint may e.g. be performed using crimping dies which e.g. are held by a hand-operated crimping tool.
When crimping a terminal to a cable end, a locator may be used to hold the terminal while crimping. The locator may comprise at least one cavity configured to hold the terminal which is to be crimped to a cable end.
The inventors of the present invention have identified a need for improvements when it comes to crimping workpieces, more precisely, improvements of the locator holding the terminal to be crimped.
An object of the present invention is thus to improve the crimping of elongated workpieces.
A further object of the present invention is to improve the holder which holds the terminal to be crimped.
The above-mentioned objects of the present invention are attained by providing an apparatus for holding at least one elongated workpiece to be crimped. The apparatus comprises a holder frame, a guide member and a locator element. The locator element has at least one holder surface which defines an elongated cavity for receiving and holding the workpiece.
