A tool for extracting a cable connector from a cable shroud. The cable and cable connector are connected to a cable shroud. The extraction tool must disengage the shroud locking tabs before the cable connector can be removed. The alignment members mate with the cable connector and, when fully inserted, disengage the shroud locking tabs. To remove the cable connector, the extraction tool must be firmly attached to the cable connector. This is accomplished by forcing the engagement pins into the engagement holes. The engagement pins are forced into the engagement holes by moving the actuator plate from the open position to the closed position causing the locking apparatus to force the engagement pins into the engagement holes.

Extraction tool for high density cable connectors

A drill collar position verifier for use with a drill bit having a drilling depth control collar positioned coaxially thereon. The drill bit is inserted in a cylindrical opening in a plastic block to a depth determined by the position of the collar. Three optical beam sources are positioned at three different predetermined depths in the plastic block. Each optical beam source projects an optical beam across the cylindrical opening and onto a corresponding optical beam detector, unless the drill bit breaks such optical beam projections. The optical beam detectors are connected to logic circuitry which is further connected to LED indicators. If the drill bit protrudes far enough through the plastic block to break the first but not the second and third optical beams, an LED is lit to indicate that the collar is positioned too close to the tip of the drill bit. If the drill bit protrudes far enough through the plastic block to break the first and second but not the third optical beam, an LED is lit to indicate that the collar is positioned within tolerances. And, if the drill bit protrudes far enough through the plastic block to break all three optical beams, an LED is lit to indicate that the collar is positioned too far away from the tip of the drill bit.

Optical drill collar position verifier

A drill collar position verifier is disclosed for use with a drill bit having a drilling depth control collar positioned coaxially thereon. The drill bit is inserted in a cylindrical opening in a plastic block to a depth determined by the position of the collar. A metallic foil and membrane switch are positioned below the plastic block of predetermined depth and are connected to logic circuitry which is further connected to LED indicators. If the drill bit does not protrude through the plastic block, an LED is lit to indicate that the collar is positioned too close to the tip of the drill bit. If the drill bit protrudes through the fixture and contacts the foil only, an LED is lit to indicate that the collar is positioned within tolerances. And, if the drill bit protrudes through the fixture and contacts both the foil and the membrane switch, an LED is lit to indicate that the collar is positioned too far away from the tip of the drill bit.
