DETAILED DESCRIPTION

As shown in FIGS. 1 and 2, a wire stripper 10 includes a housing 14 having a main body 16 and a rotatable coupling member 18 that removably receives a first bushing 22 having a tooth 24 for stripping the insulation jacket from a wire (not shown). The wire stripper 10 also includes a drive mechanism 26 for rotating the coupling member 18 and the first bushing 22 with respect to the main body 16 about a longitudinal axis 30 defined by the coupling member 18. As shown in FIG. 2, the drive mechanism 26 includes a motor 34 having a rotation axis 36, a transmission 38 terminating in a bevel pinion 42, and a drive member 46. The drive member 46 includes a ring gear 50 that is engaged by the bevel pinion 42 and an integral collar 54 rotatably supported within the housing 14 by a bearing 58. The rotation axis 36 of the motor 34 is not coaxial with the longitudinal axis 30. Specifically, the rotation axis 36 of the motor 34 is arranged at an angle α with respect to the longitudinal axis 30. In the illustrated embodiment, the angle α is 90 degrees. In some embodiments, the angle α is 20 degrees. In some embodiments, the angle α is 45 degrees. In some embodiments, such as the embodiment schematically shown in FIG. 9, the rotation axis 36 of the motor 34 is parallel to the longitudinal axis 30, and thus the angle α is 0 degrees.

As shown in FIGS. 2 and 8, the coupling member 18 has a body 62 that is coupled to the collar 54, such that the coupling member 18 is coupled for co-rotation with the drive member 46. The coupling member 18 also includes a quick release mechanism 66 to facilitate securing and removing the first bushing 22 to and from the coupling member 18. The quick release mechanism 66 includes a retainer 70 moveable between a first, locked position shown in FIGS. 2 and 8, in which the first bushing 22 is secured for co-rotation with the coupling member 18, and a second, unlocked position (not shown), in which the first bushing 22 is not secured for rotation with the coupling member 18 and is removable therefrom. The quick release mechanism 66 also includes an actuator 74 including a first end 78 that is biased away from the body 62 by a compression spring 82. The retainer 70 is coupled to a second end 86 of actuator 74 via a pivot 90.

The actuator 74 is pivotable with respect to the body 62 about a pivot 94. Because the first end 78 is biased away from the body 62, the second end 86 is biased towards the body 62, thus causing the retainer 70 to be biased toward the first position shown in FIGS. 2 and 8. The retainer 70 extends through a bore 98 in the body 62 and a bore 100 in the collar 54. As shown in FIG. 2, when the first bushing 22 is in the coupling member 18 and the retainer 70 is in the first position, the retainer 70 extends into an aperture 102 in the first bushing 22, such that the first bushing 22 is locked for rotation about the longitudinal axis 30 with the coupling member 22 and the drive member 46. When an operator moves the first end 78 of the actuator 70 toward the body 62 against the force of spring 82, the second end 86 moves away from body 62 and thereby lifts the retainer 70 into the second, unlocked position, in which the retainer 70 is removed from the aperture 102 of the first bushing 22. Thus, the first bushing 22 may be removed from the coupling member 18.

With reference to FIGS. 2-8, the wire stripper 10 also includes a depth adjustment mechanism 106 for adjusting a length of the wire along which an insulated jacket may be stripped therefrom. The depth adjustment mechanism 106 includes a tube 110, which is coaxial with the longitudinal axis 30, rotatably supported in the housing 14 by a bearing 114. The depth adjustment mechanism 106 also includes a telescoping shaft 116 having first, second, third and fourth telescoping members 118, 122, 126, 130 arranged within the tube 110 along the longitudinal axis 30, and a depth stop member 134 coupled to the fourth telescoping member 130. The depth adjustment mechanism 106 also includes a base 138 from which the telescoping members 118, 122, 126, 130, and thus the telescoping shaft 116, are able to telescope and a dial 142 coupled for rotation with the tube 110 with respect to the main body 16, such that when the dial 142 is rotated, the tube 110 rotates as well. In the illustrated embodiment, the telescoping shaft 116 has four telescoping members 118, 122, 126, 130 but in other embodiments the telescoping shaft 116 has more or fewer telescoping members.

As shown in FIGS. 2, 4-6 and 8, the tube 110 includes a helical flute 146 on the interior thereof, extending along the length of the tube 110. As shown in FIG. 3, the depth stop member 134 includes a key 150 that is arranged in the flute 146, such that when the tube 110 rotates about the longitudinal axis 30 relative to the telescoping members 118, 122, 126, 130 and the depth stop member 134, the key 150 moves along the flute 146. In this manner, the depth stop member 134 will be drawn, via the key 150, along the length of the tube 110, while the telescoping members 118, 122, 126, 130 telescope with respect to each other and the base 138 within the tube 110 to accommodate the movement of the depth stop member 134. Thus, the depth stop member 134 can be moved between at least a first position (FIGS. 4 and 8), in which a first distance D1 is defined between the depth stop member 134 and the tooth 24 of the first bushing 22, a second position (FIG. 5), in which a second distance is defined between the depth stop member 134 and the tooth 24, and a third position (FIGS. 2, 3 and 6), in which a third distance D3 is defined between the depth stop member 134 and the tooth 24. Once the tube 110 has stopped rotating, the depth stop member 134 is axially fixed in one of the first, second, or third positions, because the key 150 is arranged in the flute 146 and the telescoping shaft 116, which is also axially fixed once the tube 110 stops rotating, prevents the depth stop member 134 from being moved toward the base 138. In this manner, the depth stop member 134 provides an axial depth stop for the wire within the tube 110 during operation, as described in further detail below. In some embodiments, the depth adjustment mechanism 106 is omitted. In other words, the telescoping shaft 116, the base 138, and the dial 142 are omitted, such that the wire may pass all the way through the tube 110, thus permitting the wire to pass all the way through the wire stripper 10, providing an operator with greater variability in the length of wire that can be stripped.

In operation, the wire is inserted through the first bushing 22, coupling member 18 and into the tube 110 until it abuts against the depth stop member 134. Thus, adjusting the depth stop member 134 within the tube 110 adjusts the length of the wire along which the insulated jacket is stripped. Accordingly, when the depth stop member 134 is in the first position (FIGS. 4 and 8), all of the telescoping members 118, 122, 126, 130 of the telescoping shaft 116 are telescoped within base 138, such that the first distance D1 is a maximum distance between the depth stop member 134 and the tooth 24, thus allowing an operator to strip a maximum length of insulated jacket from the wire. When the depth stop member 134 is in the third position (FIGS. 2, 3 and 6), all of the telescoping members 118, 122, 126, 130 of the telescoping shaft 116 are telescoped to a maximum extension position within tube 110, such that the third distance D3 is a minimum distance between the depth stop member 134 and the tooth 24, thus allowing an operator to strip a minimum length of insulated jacket from the wire. As shown in FIG. 5, when the depth stop member 134 is in the second position, the second distance is less than the first distance D1 and greater than the third distance D3, such that an operator can strip an intermediate length of insulated jacket from the wire.

As shown in FIG. 7, the dial 142 includes a first indicia 154 corresponding to the first position of the depth stop member 134 (and thus the first distance D1) and visible through a display 158 on the main body 16 of the housing 14. The dial 142 also includes a second indicia corresponding to the second position of the depth stop member 134 (and the second distance), and a third indicia corresponding to the third position of the depth stop member (and the third distance D3). Thus, when the dial 142 is rotated to a position in which the first indicia 154 is visible through the display 158, the rotation of tube 110 causes the depth stop member 134 to move to the first position. Likewise, when the dial 142 is rotated to a position in which the second indicia is visible through the display 158, rotation of the tube 110 causes the depth stop 134 to move to the second position, and when the dial 142 is rotated to a position in which the third indicia is visible through the display 158, rotation of the tube 110 causes the depth stop 134 to move to the third position. In some embodiments, the first 154, second and third indicia may all indicate different whole number lengths of measurement, such as inches, millimeters, or centimeters, corresponding to the length of wire to be stripped as dictated by the corresponding position of the depth stop 134. In some embodiments, the first 154, second, and third indicia indicate fractions of measurements, such as fractions of inches, corresponding to the length of wire to be stripped as dictated by the corresponding position of the depth stop 134. In another embodiment, the display 158 is electronic, such as a liquid crystal display (LCD). In some embodiments, the dial 142 includes detents to allow the dial 142 to be stopped at incremental rotational positions corresponding to, e.g., the first, second, and third positions of the depth stop 134. In some embodiments, more than three detents may be employed to provide more than three predetermined positions of the depth stop 134. In other embodiments, the depth stop 134 is adjustable anywhere along the length of the tube 110.

With reference to FIGS. 1 and 2, the wire stripper 10 further includes a battery pack 162 that can be mounted in a battery receptacle 166 coupled to the housing 14 to provide power to the motor 34. In some embodiments, the battery pack 162 is a rechargeable power tool battery pack. The wire stripper 10 also includes a switch 170 for actuating the motor 34 and a slider switch 174 for sliding between a forward rotation mode of the motor 34 and a reverse rotation mode of the motor 34.

In operation, an operator first decides what length insulated jacket is to be stripped from a first wire having a first diameter having a nominally smaller than an internal diameter 178 of the first bushing 22. For example, the operator may decide that a minimum length of insulated jacket should be stripped. Thus, the operator then rotates the dial 142 until the third indicia is visible through the display 158. Rotation of the dial 142 causes the tube 110 to rotate relative to the telescoping shaft 116 and the depth stop member 134. Thus, the key 150 of the depth stop member 134 is moved along the rotating helical flute 146 of the tube 110 until the depth stop member 134 is in the third position, such that the third, minimum, distance D3 is defined between the depth stop member 134 and the tooth 24 of the first bushing 22 (FIG. 2).

The operator then presses the switch 170, which actuates motor 34 to rotate the bevel pinion 42 via the transmission 38. Rotation of the bevel pinion 42 causes the drive member 46 to rotate via the ring gear 50, such that the collar 54 rotates relative to the tube 110. Rotation of the collar 54 causes rotation of the coupling member 18 and, because the retainer 70 is in the first position within the aperture 102 of the first bushing 22, the first bushing 22 is caused to rotate as well. The operator then gradually inserts the first wire through the first bushing 22, coupling member 18 and tube 110 until the wire abuts against the depth stop member 134, at which point the wire stops, because the depth stop member 134 is axially fixed in the third position. As the wire travels through the first bushing 22, coupling member 18 and into tube 110, the tooth 24 rotates about the insulated jacket of the wire, thereby making a continuous helical cut that strips the jacket from the wire. Once the first wire has reached the depth stop member 134, the minimum length of wire has been stripped, and the operator may remove the first wire from the wire striper 10, which causes the stripped jacket portion to also fall out.

Once the operator has finished with the first wire, the operator may decide that a second wire having a second, larger diameter than the first wire, needs to be stripped. Because the internal diameter 178 of the first bushing 22 is too small for the second wire, the operator needs to use a new, second bushing 180 (FIG. 10) having an internal diameter 184 that is greater than the internal diameter 178 of the first bushing 22. Thus, the operator presses the first end 78 of the actuator 74, causing the retainer 70 to move from the first position to the second position, in which the retainer 70 is moved out of the aperture 102 of the first bushing 22. The operator then removes the first bushing 22 from the coupling member 18 and inserts the second bushing 180 into the coupling member 18 until the retainer 70 is biased into the aperture 102 of the second bushing 180, thereby securing the second bushing 180 to the coupling member 18 and locking it for rotation therewith. Thus, the quick release mechanism 66 provides a fast and convenient means to allow an operator to quickly switch between first and second bushings 22, 180 having different internal diameters.

In some embodiments, the first and second bushings 22, 180 may have different teeth or blades for stripping wire. In some embodiments, as shown in FIG. 10, a kit 181 includes the first bushing 22, the second bushing 180, and a third bushing 183, each of which is color coded or has other indicia to indicate what diameter wire the respective bushing is intended to strip. In some embodiments, the indicating color or indicia is located on a front face 182 of the first bushing 22, a front face 185 of the second bushing 180, and a front face 187 of the third bushing 183, making it easily visible to a user when the bushings 22, 180, 183 are in a typical bushing storage case. The third bushing 183 has a larger internal diameter 189 than the first and second internal diameters 178, 184. The first bushing 22 has a first color 191, the second bushing 180 has a second color 193, and the third bushing 183 has a third color 195, with each of the first, second, and third colors 191, 193, 195 being different from one another.

With continued reference to FIG. 10, the kit 181 also includes a chart 197 that helps an operator quickly identify which of the first, second, and third colors 191, 193, 195 correspond to first, second, and third wire sizes 199, 201, 203, such as 600, 750, and 1,000 MCM (thousands of circular mils). The first, second and third wire sizes 199, 201, 203 respectively correspond the to the first, second, and third internal diameters 178, 184, 189 of the first, second, and third bushings 22, 180, 183. In the illustrated embodiment, the first, second, and third wire sizes 199, 201, 203 are listed directly on boxes with the first, second, and third colors 191, 193, 195. Thus, with the chart 197, an operator can quickly select either the first, second, or third bushing 22, 180, 183 based on the color coding of the bushings 22, 180, 183 for what size wire needs to be stripped.

The operator then must decide what length insulated jacket is to be stripped from the second wire. For example, the operator may decide that a maximum length of insulated jacket should be stripped. Thus, the operator then rotates the dial 142 until the first indicia is visible through the display 158. Rotation of the dial 142 causes the tube 110 to rotate relative to the telescoping members 118, 122, 126, 130 and the depth stop member 134. Thus, the key 150 of the depth stop member 134 is moved along the rotating helical flute 146 of the tube 110 until the depth stop member 134 is in the first position, such that the first, maximum, distance D1 is defined between the depth stop member 134 and the tooth 24 of the second bushing 180. The operator then repeats the stripping operation described above, concluding with gradual insertion of the second wire through the second bushing 180, which has an internal diameter that is nominally greater than the second wire. The second wire is inserted through the coupling member 18 and tube 110 until the second wire abuts against the depth stop member 134. As the second wire travels through the second bushing 180, coupling member 18 and into tube 110, the tooth 24 rotates about the insulated jacket of the second wire, thereby making a continuous helical cut that strips the jacket from the second wire. Once the wire has reached the depth stop member 134, the maximum length of the second wire has been stripped, and the operator may remove the second wire from the wire striper 10, which causes the stripped jacket portion to also fall out.

In some operations, an operator may wish to adjust the setting of the depth adjustment mechanism 106 during operation, in which case the operator simply turns the dial 142 while depressing the trigger 170. Because the tube 110 rotates relative to the depth stop member 134 and the drive member 46, the depth stop member 134 can therefore be adjusted on the fly during operation.

In some embodiments, the drive member 46 is omitted and instead, a belt drive mechanism is employed with a belt arranged about and engaged with the first bushing 22. In operation, the belt drive system is driven by the drive mechanism 26 to pull the belt about the first bushing 22, thereby rotating the first bushing 22 via friction. In other embodiments, the drive member 46 may remain but the ring gear 50 replaced by a pulley around which the belt may be arranged.

FIG. 9 schematically shows an embodiment of the wire stripper 10 in which the rotation axis 36 of the motor 34 is parallel to the longitudinal axis 30. In the embodiment of FIG. 9, the motor 34, via the transmission 38, drives a gear, such as a spur gear 186, that is engaged with a drive member 190. The drive member 190 drives rotation of the coupling member 18, which receives the first bushing 22, in the same manner as the embodiment of FIGS. 1-8. In the embodiment of FIG. 9, the depth adjustment mechanism 106 is omitted and instead, the housing 14 includes a cavity 194 and an opening 198 on a side of the housing 14 opposite the first bushing 22 that provides access to the cavity 194.

In operation of the embodiment of FIG. 9, the operator then presses the switch 170, which activates the motor 34 to rotate the spur gear 186 via the transmission 38. Rotation of the spur gear 186 causes the drive member 190 to rotate the coupling member 18, which causes the first bushing 22 rotate. The operator then gradually inserts a wire 202 through the first bushing 22, the coupling member 18, the cavity 194, and the opening 198, such that the wire 202 passes through the housing 14 of the wire stripper 10. As the wire 202 travels through the first bushing 22, the tooth 24 rotates about the insulated jacket of the wire 202, thereby making a continuous helical cut that strips the jacket from the wire 202.

Because the wire 202 can pass through the wire stripper 10, the operator can make a longer cut along the wire 202 than in the embodiment of FIGS. 1-8, in which the length of the cut is limited by the depth adjustment mechanism 106. When the operator is satisfied with the length of wire 202 that has been stripped, the operator may then release the switch 170 and remove the wire 202 from the wire striper 10 in a direction opposite that it was inserted, such that the wire 202 passes back through the opening 198, the cavity 194, the coupling member 18, and the first bushing 22, causing the stripped jacket portion to also fall out.
