Abstract
A crimper tool for use in attaching lugs to the metallic sheath covering on fiber optic cables includes a pair of blocks, with a trough formed in each block to accommodate the cable when one block is placed on top of the other. Each block includes at least one slot for positioning a proper-sized die to perform the crimping action. The use of this block crimper tool is particularly advantageous when a hand-held crimper is too small to accommodate a large diameter fiber cable.
Claims8
A crimper tool for attaching a lug element to an exposed metallic sheath layer of a fiber optic cable, said crimper tool comprising
- a bottom block including a longitudinal trough formed in the top surface thereof, said bottom block further comprising at least one die slot for accommodating at least one crimping die;
- a top block including a longitudinal trough formed in the bottom surface thereof such that when the top block is mated with the bottom block the troughs align and form an area for placing a fiber optic cable to be crimped, said top block further comprising at least one die slot for accommodating at least one crimping die, said at least one top block die slot aligning with the at least one bottom block die slot when said top block is mated with said bottom block;
- and
- at least one pair of crimping dies to be inserted in a pair of aligned die slots, wherein a die of said at least one pair may be struck to attach a lug element onto an exposed metallic sheath layer of a fiber optic cable disposed in the aligned troughs.
A method of crimping an electrical connection lug onto a section of fiber optic cable, the method comprising the steps of:
- a) stripping a fiber optic cable to expose a metallic sheath layer;
- b) inserting a lug of appropriate size over the exposed section of fiber optic cable;
- c) providing a pocket crimping tool comprising a bottom block including a longitudinal trough formed in the top surface thereof for accommodating the exposed section of fiber optic cable, said bottom block further comprising at least one die slot for accommodating at least one crimping die and a top block including a longitudinal trough formed in the bottom surface thereof such that when the top block is mated with the bottom block the troughs align and accommodate said fiber optic cable and inserted lug, said top block further comprising at least one die slot for accommodating at least one crimping die, said at least one top block die slot aligning with the at least one bottom block die slot when said top block is mated with said bottom block;
- d) inserting appropriate-sized dies in the bottom and top block die slots;
- and
- e) striking a die with a force sufficient to crimp the lug into position around the exposed section of fiber optic cable.
