Definitions

  • This invention relates in general to cable stripping tools and deals more particularly with an improved tool having spaced apart cutting elements for both cutting and stripping axially spaced apart inner and outer layer of material from a coaxial cable or the like to expose a predetermined portion of a coaxial conductor contained within the cable.
  • an improved conductor stripping tool comprises a pair of jaws which include a stripping jaw and a clamping jaw and means supporting the jaws for movement between open and closed positions.
  • a pair of spaced apart cutting and stripping elements are mounted on the stripping jaw for cutting and stripping successive coaxial layers of cable material at axially spaced apart locations along an associated cable position between the jaws when the jaws are in closed position.
  • a clean-out means is provided for removing scrap material lodged between the cutting and stripping elements in response to opening of the jaws.
  • Fig. 1 is a side elevational view of a cable stripping tool embodying the present invention shown with the jaws thereof in closed position.
  • Fig. 2 is a plan view of the cable stripping tool of Fig. 1.
  • Fig. 3 is similar to Fig. 1 but shows the jaws in open position.

  • the partition wall 34 cooperates with the handle rear portion and with portions of the bottom and sidewalls 28 and 30,30 to define an upwardly open cavity 38.
  • the partition wall also cooperates with portions of the bottom and sidewalls at the forward end of the handle to define a forwardly and upwardly open recess 40.
  • the stripping jaw 12 may form an integral part of one of the handles.
  • the stripping jaw is partially defined by a replaceable jaw cartridge, indicated generally a 42, which is received and releasably retained within the recess 40.
  • the jaw cartridge 42 preferably comprises a generally rectangular block of dielectric plastic material and has outwardly directed flanges at its front end extending along its bottom and side edges for engaging the forwardly facing surfaces of the bottom and sidewalls 28 and 30,30 when the jaw cartridge 42 is assembled with the handle 12 within the recess 40.
  • the upper surface of the jaw cartridge 42 cooperates with the upper surfaces of the sidewalls 30,30 at the forward end of the handle to define an upwardly facing abutment surface 44.
  • a generally semi- cylindrical cable receiving channel 46 is defined by the jaw cartridge and associated forward end portions of the sidewalls 30,30 and opens upwardly through the abutment surface 44.
  • the cable receiving channel 46 has a radius substantially equal to the radius of an associated cable to be stripped.
  • the cutting and stripping blades 20 and 22 are mounted in fixed position on the jaw cartridge 42 within the cable receiving channel 46 and are preferably formed from flat metal, imbedded within the jaw cartridge 42.
  • the blades have edge portions exposed within the cable receiving channel and extend across the channel. More specifically, the blades 20 and 22 are disposed in radial planes and are axially spaced apart relative to each other along the axis of the semi- cylindrical cable receiving channel 46.
  • the cutting edge of the blade 20 is preferably disposed within the plane of the abutment surface 44 and has an central notch 48 opening upwardly through it for receiving a conductor of an associated coaxial cable to be stripped.
  • the cutting edge of the blade 22 is preferably parallel to the cutting edge of the blade 20 but spaced downwardly from it.
  • the cutting edge of the blade 22 is spaced above the bottom of the channel 46 a distance substantially equal to the thickness of an outer insulation jacket on a cable to be stripped.
  • a vertically disposed rearwardly and upwardly opening central notch 50 is formed in the blade cartridge 42 for registry with the slot 36 and opens through the cable receiving channel 46 between the blades 20 and 22.

  • a torsion spring 54 received within an associated slot in the upper handle 18 and coiled about the pivot fastener 52 acts between the upper handle 18 and the bottom wall 28 to bias the upper handle 18 in counterclockwise direction about the axis of the fastener 52 and toward its closed jaw position, as it appears in Figs. 1 and 5 of the drawings.
  • the upper or clamping jaw 14 is defined by a groove 58 formed in the forward end portion of the upper handle 18.
  • the latter groove has an inverted generally V-shape cross-section and extends transversely through the handle 18 in generally axially parallel relation to the cable receiving channel 46.
  • the clean-out member 24 comprises an elongated rigid rod mounted in fixed cantilever position on the upper handle 18.
  • the rod 24 extends forwardly of the handle through the slot 36 and into the notch 50 when the jaws are in closed position. Operation of the handles 16 and 18 to move the jaws to open position causes the clean-out rod 24 to sweep upwardly through the cable receiving channel, within the space between the blades 20 and 22.

  • a layer of braided wire 66 coaxially surrounds the inner insulation layer 64 and the conductor 62, substantially as shown.
  • An outer layer of electrical insulating material 68 coaxially surrounds the braided metallic layer 66.
  • An end portion of a cable to be stripped such as the cable 60, is inserted into the tool 10 below and in general axially alignment with the clamping groove 58 and above the clean-out member 24.
  • the cable may, if desired, be positioned with its free end disposed in the plane of an associated sidewall 30 to gauge the length of conductor 62 to be exposed.
  • the jaws are then allowed to close on the cable in response to closing force exerted by the spring 54.
  • the clamping jaw forces the cable downwardly against the blades 20 and 22 and toward seating engagement within the cable receiving channel 46.
  • squeezing pressure may be manually applied to the forward ends of the jaws to fully close the jaws and cause the cutters 20 and 22 to cut into the cable 60.
  • the tool 10 is rotated about the axis of the cable 60, using the finger receiving recess 26 at the rear end of the lower handle, to form annular cuts in the cable.
  • the tool Upon completion of the cutting operating the tool is drawn away from the cable in an axial direction with the jaws in closed position to strip the cut insulation from the end portion of the cable, thereby exposing the terminal end portion of the conductor 62 and portions of the insulating layer 64 and the conductive layer 66 leaving the cable end portion in a condition in which it appears in Fig. 9.
  • At least some of the jacket material removed from the cable will remain within the closed jaws 12 and 14 after the cable has been stripped.

Abstract

Un outil de dévêtissage de câbles coaxiaux possède une paire de mâchoires opposées (12, 14), la mâchoire (12) étant une mâchoire de dévêtissage et la mâchoire (14) étant une mâchoire de serrage supportées aux extrémités associées d'une paire de poignées à mouvement pivotant. La mâchoire de dévêtissage possède une paire de lames espacées de coupe et de dévêtissage (20, 22) pour couper les parties axialement espacées d'un câble à dévêtir lorsque le câble est serré par les mâchoires et que l'outil tourne autour de l'axe du câble. Les mâchoires sont normalement sollicitées par un ressort vers la position fermée et se déplacent vers la position ouverte en réponse à l'actionnement des poignées. Une tige nettoyeuse (24) montée en position de porte-à-faux sur l'une des poignées balaye l'espace délimité entre les lames pour déloger les déchets emprisonnés entre les lames à chaque fois que les poignées sont actionnées pour ouvrir les mâchoires.
