Abstract
A cable armor stripper is configured to have a blade controllably penetrating the armored cable at the desired depth in response to applying an external sforce.
Description
- 1. Field of the Invention
- The invention relates to a cable sheath cutter for stripping the insulation or like sheath from electrical cables.
- 2. Description of Prior Art
- Cables and, particularly, power cables are conventionally formed with insulated inner strands surrounded by a metallic sheath, which is usually corrugated. In order to terminate, to test, to join and to repair such cables, the outer sheath must be stripped away so that lengths of the inner strands can be exposed, inspected, separated and worked on as required.
- Typically, a cable cutter includes a handle carrying a cutting blade projecting from a shoulder at one end of the handle, and a cable clamp, which extends transversely of that end and which is spring urged towards the handle. In use, the cable is located between the clamp and cutter and the spring urges the cable so that the blade penetrates the sheath until the shoulder abuts the sheath. The tool is then rotated about the axis of the cable to make a peripheral cut, which enables the sheath to be peeled off the core or conductors of the cable.
- In general, the cable cutter of the type described above has rather a complicated force transmission mechanism translating a force applied either manually or by a rotary motor into rotational motion of the blade. Sometimes, such a structure has substantial dimensions rendering the cable cutter inconvenient in use. This inconvenience is even more noticeable due to the geometry of the cable cutter and particularly to its frontal cable engaging area, which is typically relatively large.
- A need therefore exists in a manually or battery operated cable cutter capable of effectively producing cuts even in confined areas.
- A cable armor stripper provided with an adjustable frontal area, which is configured to reliably engage differently dimensioned cables and to produce uniform cuts in confined areas, meets this need.
- The inventive cable armor stripper is ergonomically configured to have a two-lever assembly providing a support for the cable to be stripped, a blade and blade actuating assembly, as well as for a cable adjustment mechanism structured to adjust the desired space between the cable support and the blade. The structure of the inventive device is characterized by the following advantages:
-
- Compactness;
- Simplicity; and
- Ability to produce a uniform cutting force resulting in the uniformly deep cut.
- It is, therefore, one of the objects of the invention to provide a cable armor stripper with a simple and effectively operating structure;
-
- A further object of the invention is to provide a cable armor stripper with a structure allowing the user to operate the inventive cable armor stripper effectively in confined areas;
- Still a further object of the invention is to provide a cable armor stripper with a simply structured cable support mechanism allowing the user to grip variously dimensioned cables in a simple and reliable manner.
- The above and other features, advantages and object will become more readily apparent from the following specific description accompanied by a set of drawings, in which:
-
FIG. 1 is an isometric view of a manually actuated motorized cable armor stripper configured in accordance with one embodiment of the invention; -
FIG. 2 is a cross-sectional view of the cable armor stripper ofFIG. 1 ; and -
FIG. 3 is an isometric view of a motorized cable armor stripper configured in accordance with a further embodiment of the invention. -
FIG. 4 is a bottom view of a motorized cable armor configured in accordance with another embodiment of the invention. - Referring to
FIGS. 1-2 , a manually operatedcable armor stripper 10 has anelongated body 12 provided on its proximal end with afolding lever 16 transmitting a user applied torque, as indicated by arrow T (FIG. 1 ), to arotary blade 14 via acentral shaft 18. Depending on the geometry of teeth provided on theblade 14, thecable stripper 10 may be provided with a ratchet mechanism configured to provide rotation of thecentral shaft 18 in one sense, or may have thefolding lever 16 directly actuate theshaft 18 in opposite directions. - The ratchet mechanism includes a
ratchet lever 20 formed integrally with aratchet 26 and aratchet shaft 22, which is provided with an array ofteeth 25 meshing with theteeth 25 of theratchet shaft 22. The teeth are so configured that rotation of the ratchet lever is translated to central shaft only in one or cutting direction of the blade resulting in a longitudinal cut along the armor. To ensure the desired position of theratchet 26, it is biased towards a distal end of thebody 12 by aspring 24 braced against acentral shaft 18 and theratchet lever 20. Rocking thefolding lever 16 in a direction opposite to the cutting one disengages the ratchet lever from the ratchet shaft, which is rotatably fixed to thecentral shaft 18 by apin 45. In use, therefore, upon pivoting the folding lever aboutfulcrum 42 so that it extends substantially perpendicular to the shafts, the user reciprocally rocks thefolding lever 16 producing, thus, a longitudinal cut every time the folding lever rotates in the cutting direction. Proper positioning of thefolding lever 16 with respect to theratchet lever 20 during rocking is realized by asecond spring 30 placed in one of these two levers and pressing against aball 32, which is received in the other lever. - Another embodiment of the motion transmitting mechanism includes a structure, in which the
blade 14 has so called isometric teeth allowing the blade to cut in opposite directions. This configuration does not require a ratchet mechanism and includes thefolding lever 16 directly coupled to thecentral shaft 18. In use, thus, rotation of thefolding lever 16 in either direction actuates theblade 14 - The
housing 28 is generally configured as an elongated sleeve made from a variety of materials including various metals and plastic structures.End couplers housing 28, respectively, secure thecentral shaft 18 and theblade 14 against axial displacement within thehousing 28. While thehousing 28 can be made in one piece, it is preferred to assemble it using multiple parts or portions, wherein thedistal end 38 of thehousing 28 is provided with ablade guard 40 extending from this distal end radially outwards to accommodate theblade 14. - A cable support and blade penetration assembly 46 (
FIG. 1 ) is provided with aclamp 44, configured to receive differently dimensioned armored cables, and with ablade actuating assembly 48, which includes abody support 50 and ahandle 52. Thebody support 50 extends along thebody 12 and is shaped with aninner surface 54 extending substantially complementary to a body segment, which is juxtaposed with this surface, and removably attached thereto at 56 (FIG. 1 ) by its proximal end. The distal end of thesupport 50 is coupled to theclamp 44 and is biased away from the distal end of thebody 18 by aresilient element 58, such a compression spring or a leaf spring. Upon applying a compressive force to the distal ends of thesupport 50 and thebody 18, the user can overcome the spring force and displace the distal ends towards one another so that theblade 14 would extend through aslit 60 of theclamp 44, as explained below. According to one modification, the clamp and the body support may be formed as a one-piece element. Alternatively, the body support is removably mounted to the rear side of the clamp, as shown inFIGS. 1 and 2 . - To prevent uncontrollable displacement of the
blade 14, which may result in an overly deep cut damaging the cable, astopper 58 formed either on thehandle 52 or thebody 18 extends therebetween and presses thereagainst by its opposite ends in the desired cutting position of theblade 14. As is shown inFIG. 2 , thestopper 58 is rotatably mounted on theclamp 44 and, thus, terminates at a distance from thehandle 52 in a rest position when no force is applied to thebody 18. Rotating thestopper 58 relative to thebody 18 varies a distance between its free end and thehandle 52 in the rest position of theblade 14 and establishes the desired blade penetration. Any other structure of the stopper, such as a telescopic one, can be used as well. In use, upon gripping thebody 18 and thehandle 52, a force generated by the user causes displacement between thebody 18 and the handle, which, in turn, brings the blade through theslit 60, until the free end of thestopper 58 abuts the handle. Such abutment corresponds to a cutting position of theblade 14, in which the latter protrudes through theslit 60 of theclamp 44 into the cable at the desired distance sufficient to slit only the cable's armor. - Variously directed bending forces accompany compression of the
body 18 and thehandle 52, which is pivotally attached by its distal end to theclamp 44. To accommodate these forces and allow thebody 18, thesupport 50 and thehandle 52 to establish the cutting position of theblade 14, the handle is made from a flexible material. Flexibility of the handle allows its distal end 66 (FIG. 2 ) to keep transferring the external force after theproximal end 64 of the handle has contacted the outer surface of thesupport 50. As a result, the distal ends of thebody 18 andsupport 50 continue to move towards one another until theblade 14, attached to the distal end of thebody 18, is displaced to its cutting position. Linearity of the displacement of thebody 18 is provided by a pair of rails 88 (FIG. 1 ) fixed to theclamp 44 and extending through channels formed in theblade guard 40. - The
handle 52 may be made from steel or any other flexible material acting as aleaf spring 62 having itsproximal end 64 angled to urge against thebody support 50 before the distal end of the handle is brought into contact with thestopper 58. For the user's convenience, theleaf spring 62 is enveloped in a plastic cover ergonomically configured to conveniently fit the user's hand. - Securement of the cable within a
front channel 68 of theclamp 44, which is formed between relatively narrow 78 and relatively wide 76 jaws of the clamp, is provided by ahead 72 of astud 70 coupled to theend 66 of thehandle 52. As thehandle 52 moves towards thebody 18 after positioning the cable in thefront channel 68, thehead 72 of thestud 70 protrudes from thejaw 76 and presses against the cable topped by thejaw 78 in the cutting position of theblade 14. To control a distance at which thehead 72 extends in a space between thejaws outer end 71 of the stud extends through a bore formed thehandle 58 and can be operated by a screwdriver. Thejaw 76 has acentral rib 74 recessed to form a guide for correct linear displacement of thehead 72 towards the cable. Thehandle 52 is biased away from thebody support 50 by aspring 80 braced between the outer side of the relativelywide jaw 76 and the head of thestud 70, which may be removably or permanently mounted to thehandle 52. When the external force is ceased, theblade 14 withdraws via theslit 60 made in the relativelynarrow jaw 78 whereas thehandle 52 pivots about apin 82 to a position shown inFIGS. 1 and 2 under a spring force generated by thespring 80. - Referring to
FIG. 3 , a motorizedcable armor stripper 90 configured in accordance with another embodiment of the invention is configured in a manner essentially similar to the manually operatedstripper 10. In particular, thearmor stripper 90 has anelongate body 92 having a proximal portion thereof housing a rechargeable and/orreplaceable battery 94 and distal portion provided with amotor 96 and ablade 98. Once the cable is properly positioned in aclamp 106 in a manner, as described above, increasing pressure on ahandle 102 will bring aproximal end 104 of a leaf spring enveloped by thehandle 102 in contact with aswitch 100 actuating themotor 96. The leaf spring is riveted to adistal end 108 of thehandle 102 thus preventing crushing of the cable casing by bowing against abody support 110. - When the
motor 96 starts rotating, further compressing thehandle 102 and thebody 92 together brings the rotatingcircular blade 98 through theslit 60 in contact with the armored cable in the cutting position of the blade. As discussed in detail in reference to the manually operated cable armor stripper, as the pressure generated by the user is increase, the blade cuts through the armored cable until the desired depth of blade penetration is reached. Releasing the pressure brings back all the parts in the rest position of the blade and releases the processed cable. -
FIG. 4 illustrates the another embodiment of the present invention configured to have theclamp 44 positioned with respect to the longitudinal axis of thebody 12 at an angle differing from a right angle to produce a helical cut on the cable. Structurally theclamp 44 is provided with the upper 78 andlower jaw 76 bridged by a rear wall 118 (FIG. 2 ) which is inclined at the desired angle different from the right with respect to the longitudinal axis A-A. Since the cable to be cut extends along and presses against the rear wall 118, the desired angular position of the cable is easily established. The stripper of the present invention, thus, can be provided as a kit including differently shapedclamps 44 removably attachable to thebody 12 byscrews 112. A number ofclamps 44 configured to establish a desired angle ranging from 90° to any angle including, for example 60°, can be provided in the kit for the user's convenience - The above description should not be construed as limiting, but merely as exemplifications of preferred embodiments. Those skilled in the art will envision other modifications within the scope and spirit of the claims appended hereto.
