Shielded conduit cutting device for small BX electrical cables
View Patent ↗A cutting device for relatively small cable including, among others, fiber optic cable and BX electrical cable is configured with removably coupleable adapter inserted between the top and bottom portions of the device which pivot relative to one another so as to displace a cutter to a cutting position. The adapter is configured to reduce a cable receiving space formed in the bottom portion of the device so as to center a small cable relative to the cutter which is operative to split the shield of the cable without damaging electrical conductors of the cable.
1. A cutting device for splitting a shield of a cable, comprising:
an elongated casting having a longitudinal axis and configured with top and bottom portions which are pivotally coupled to one another, the bottom portion being configured to receive the cable;
a cutter coupled to the top portion of the casting and displaceable therewith towards a cutting position so as to split the shield of the cable upon actuation of the cutter; and
an adapter insertable on the bottom portion so as to axially slide therealong in response to an external force, the adapter being configured to receive the cable in a predetermined position thereof in which the cable is centered relative to the cutter;
one or more frictions elements configured to generate friction with the adapter during the sliding motion thereof; and
an adjustable screw coupled to the bottom portion so as to cause the adapter to move laterally on the bottom upon displacing the adapter to the predetermined position.
2. The cutting device of claim 1 , wherein the adapter is removably mounted to the bottom portion of the casting and configured to receive and displace the cable laterally relative to a longitudinal axis of the casting to the predetermined position of the cable.
3. The cutting device of claim 2 , further comprising a first displacement control unit coupled to one of opposing surfaces of the bottom and top portions of the casting, respectively, the first displacement control unit including a shim stop rotatably slidable between extreme positions thereof and operable to control a depth of penetration of the cutter into a shield of the cable.
4. The cutting device of claim 3 , wherein the first displacement control unit further includes a screw mounted to the top portion and displaceable towards the bottom portion so as to press against the shim stop in one of the positions of the shim stop thereby allowing the cutter to penetrate the shield at a first depth, and to press against a surface of the bottom portion facing the top portion upon rotating the shim stop to another position in which the cutter penetrates the shield at a second depth greater than the first depth.
5. The cutting device of claim 4 , further comprising a biasing unit coupled to the bottom portion of the casting and operative to bias the top and bottom portions away from one another.
6. The cutting device of claim 1 , further comprising a clamping handle having a distal end thereof pivotally mounted to an underside of the bottom portion of the caster, the clamping handle being provided with a cable stopper controllably penetrating the bottom portion so as to prevent displacement of the cable relative to the casting.
