[0023] Generally referring to the drawings, various different embodiments of a hand tool, specifically a multi-purpose or multi-functional tool, are shown. The various different embodiments of the multi-purpose tool discussed herein include an innovative biasing member that is used to engage with a tool tip (such as a wire stripper tool tip). The applicant has determined that it is desirable to maintain a narrow profile of the tool shaft and / or the tool tip holder while providing a spring force to secure the wire stripper tool tip to the tool shaft and / or the tool tip holder. Compared with conventional methods of securing a tool tip (such as a ball detent and a spring that require a relatively large wall thickness of the tool shaft to accommodate the securing components), the biasing member discussed herein does not require a relatively large wall thickness. In various different embodiments, the biasing member is a wire spring. Compared with conventional securing methods (such as using a C-shaped clamping spring), the height of the wire spring developed by the applicant is relatively long compared to the height of the tool shaft. The applicant believes that the size and / or shape of the biasing member of the multi-purpose tool discussed herein allows for a secure holding of the wire stripper tool tip while maintaining the narrow profile of the tool shaft.

[0024] Refer toFigure 1 , which shows a multi - purpose handheld tool according to an exemplary embodiment, shown as a multi - purpose tool that combines a wire stripper and a screwdriver. The multi - purpose tool 10 can be operated as a wire stripper to terminate wires at connectors, cross - connect panels, terminal jacks, etc., and can also be operated as a screwdriver to rotate and drive fasteners (e.g., Phillips - head screws, flat - head screws, etc.). As is generally understood, there are various different types of (e.g., impact, non - impact) wire strippers. Impact wire strippers include an impact mechanism (i.e., a pin rammer, a hammer spring) to provide the force for cutting, while non - impact wire strippers can alternatively include a double - sided blade without any impact mechanism.

[0025] The multi - purpose tool 10 includes a housing or tool shaft 12 and a handle 14. The handle 14 includes a body 32 and a grip portion 28 that at least partially surrounds the body 32. In various different embodiments, the grip portion 28 includes a plurality of ridges to improve the user's grip on the handle 14. In a specific embodiment, the grip portion 28 is formed of a material (e.g., rubber, etc.) that provides friction and is different from the material of the body 32 of the handle 14.

[0026] A connector 26 is positioned between the shaft 12 and the handle 14. The connector 26 is shaped to fit within a hole 27 in the body 32 of the handle 14. The hole 27 will have a shape corresponding to the shape of the connector 26. In various different embodiments, the connector 26 has a polygonal shape. In various different specific embodiments, the connector 26 has a generally hexagonal shape (i.e., a hexagonal prism). The polygonal shape prevents unwanted rotation between the connector 26 and the handle 14. As will be discussed in more detail below, the connector 26 engages with the shaft 12 to inhibit rotation of the shaft 12 relative to the handle 14. Thus, when the user rotates the handle 14, the shaft 12 and the tool bit 30 rotate together with the handle 14.

[0027] Reference Figures 1 to 3 , the shaft 12 includes a first end 16 and a second end 18 opposite the first end (see, for example Figure 4)。The shaft 12 defines a longitudinal axis 34 that extends between a first end 16 and a second end 18. The shaft 12 includes a generally cylindrical portion 20. A slot 22 is defined within the generally cylindrical portion 20 of the shaft 12 adjacent the first end 16. The slot extends along the longitudinal axis 34 in an orientation generally parallel to the longitudinal axis 34. A biasing member (shown as spring 24) is positioned within the slot 22. In a specific embodiment, the spring 24 is a wire spring. The multi-purpose tool 10 includes a removable wire-stripping tool tip 30. The wire-stripping tool tip 30 extends beyond the first end 16 of the shaft 12. The wire-stripping tool tip 30 can include a standard configuration, such as a 110-type terminal or a 66-type terminal. In various different embodiments, the wire-stripping tool tip 30 is reversible and includes, for example, both a 110-type terminal and a 66-type terminal. As is generally understood, 66-type terminals are used to connect wires and come in various different sizes (e.g., A, B, and M), and are configured to terminate wires (such as 22 to 26 American Wire Gauge (AWG)). As is generally understood, 110-type terminals are an updated version of 66-type terminals, having a different shape and being configured to terminate wires (such as 22 to 26 American Wire Gauge (AWG)).

[0028] Reference Figures 4 to 6 , a top view, a bottom view, and an exploded view of the multi-purpose tool 10 with the handle 14 removed are shown, in accordance with an exemplary embodiment. The handle 14 and the shaft 12 are removably coupled such that either the first end 16 or the second end 18 is received within the handle 14. A height H1 of the shaft 12 is defined between the first end 16 and the second end 18 of the shaft 12.

[0029] The first end 16 of the shaft 12 includes a first recess 40 configured to receive the tool tip 30. At the second end 18, the shaft 12 includes a second recess 38 configured to receive a tool tip holder 36 and a plurality of tool tips (shown as reversible screwdriver tips 42, 58). The reversible screwdriver tips 42, 58 are removably coupled to the tool tip holder 36. Each of the reversible screwdriver tips 42, 58 includes a hole 70, 68 configured to receive a biasing member shown as a spring 54 and a ball 56, which together fix the tips 42, 58 to the tool tip holder 36.

[0030] The tool tip holder 36 includes a first end 60 and an opposite second end 64. The first end 60 of the tool tip holder 36 includes a recess 64 configured to receive the reversible tool tip 58. At the second end 62, the tool tip holder 36 includes a recess 66 configured to receive the reversible tool tip 42.

[0031] When the multi - purpose tool 10 is assembled, the shaft 12 is positioned within the connector 26. Specifically, the connector 26 includes an inner or inward - facing surface 50 that defines a passage 46 extending through the connector 26. When the multi - purpose tool 10 is assembled, the shaft 12 is positioned within the passage 46 of the connector 26 and extends through the passage of the connector. The shaft 12 further includes a bore 52 defined in a generally cylindrical portion 20 of the shaft 12. The bore 52 extends in a direction generally perpendicular (i.e., 90 degrees plus or minus 10 degrees) to the longitudinal axis 34 and is configured to receive a spring 54 and a ball 56. When the multi - purpose tool 10 is assembled, the spring 54 is positioned within the bore 52 and provides a force to the ball 56. The ball 56 engages the inward - facing surface 50 of the connector 26.

[0032] When the second end 18 is received within the handle 14, a protrusion 44 on the outer surface of the cylindrical portion 20 engages a corresponding recess 48 of the connector 26, and the shaft 12 is in a first position (see, for example Figure 1 ). Similarly, when the first end 16 is received within the handle 14, the protrusion 44 engages the recess 48 of the connector 26, and the shaft 12 is in a second position. The engagement between the protrusion 44 and the connector 26, together with the engagement between the ball 56 and the connector 26, resists rotation of the shaft 12 relative to the connector 26. Thus, the shaft 12 is convertible relative to the handle 14 between the first position and the second position. When the shaft 12 is in the second position, the tool 10 can be used as a screwdriver. When the shaft 12 is in the first position, the tool 10 can be used as a wire - stripping tool, as described in more detail below.

[0033] The connector 26 further engages the body 32 of the handle 14. In various embodiments, the outer surface of the connector 26 includes a plurality of ridges 47 that are configured to engage the body 32 and resist rotation of the connector 26 relative to the body 32 of the handle 14. Thus, when the user rotates the handle 14, the shaft 12 and the tool bit 30 rotate together with the handle 14.

[0034] To operate the multi - purpose tool 10 as a wire - stripping tool, the user presses the wire - stripping tool bit 30 against an exposed wire to terminate the wire. Specifically, the tool bit 30 includes an angled or cutting portion for terminating the wire. To operate the multi - purpose tool 10 as a screwdriver, the user removes the shaft 12 from the handle 14, then reverses the shaft 12 and inserts the first end 16 into the handle 14. The recess 48 in the connector 26 receives the protrusion 44 to inhibit relative rotation between the shaft 12 and the handle 14 during use of the multi - purpose tool 10. Reversible screwdriver bits 42, 58 can be used to perform the desired operations on fasteners or other workpieces.

[0035] Reference Figures 7 to 8, details of the first end 16 of the shaft 12 are shown according to an exemplary embodiment. The spring 24 is positioned within the slot 22 defined in the generally cylindrical portion 20 of the shaft 12 such that the spring 24 extends into the recess 40. The tool bit holder 39 is positioned within the recess 40. In other words, when the tool bit holder 39 is positioned within the recess 40, a first section of the spring 24 extends into the shaft of the tool bit holder 39 to secure the spring 24 to the tool bit holder 39. In particular embodiments, the tool bit holder 39 is integrally formed with the shaft 12 and / or the recess 40. In other embodiments, the bit holder 39 is removably coupled to the shaft 12.

[0036] refer to Figure 9 , showing the first end 16 along the Figure 7 9-9 of FIG. The tool bit holder 39 includes an upper portion (shown as an upper cylindrical portion 72), an intermediate portion (shown as an intermediate cylindrical portion 74), and a lower portion (shown as a lower cylindrical portion 76). The intermediate cylindrical portion 74 is positioned between the upper cylindrical portion 72 and the lower cylindrical portion 76. The lower cylindrical portion is positioned between the upper cylindrical portion 72 and the second end 18 of the shaft 12.

[0037] The spring 24 includes a first or upper section 78, a generally vertical (at Figure 9 12 ) or longitudinal section 80, and a second or lower section 82. Typically, the upper section 78 of the spring 24 extends into the shaft of the tool bit holder 39 near one end of the tool bit holder 39, while the lower section 82 of the spring 24 extends into the shaft of the tool bit holder 39 adjacent the opposite end of the tool bit holder 39. Thus, in this arrangement, the upper section 78 and spring end 85 of the spring 24 are located in the longitudinal direction (i.e., along the longitudinal axis 34 of the shaft 12) between the open end 41 of the tool bit holder 39 and the lower section 82, and the lower section 82 is located in the longitudinal direction between the other end 43 of the tool bit holder 39 and the upper section 78. The longitudinal section 80 of the spring 24 extends along the longitudinal axis 34 of the shaft 12. The upper section 78 and the lower section 82 of the spring 24 extend from the longitudinal section 80 , and thus the longitudinal axis 34 of the shaft 12 , in a generally perpendicular (ie, 90 degrees plus or minus 10 degrees) direction or orientation.

[0038] When the multi-purpose tool 10 is assembled, the upper section 78 of the spring 24 extends through the wall of the upper cylindrical portion 72 and specifically through the hole 84 of the upper cylindrical portion 72. A spring passage 86 extends through the first end 16 of the shaft 12 and the lower cylindrical portion 76. In a particular embodiment, the spring passage 86 extends through a majority of the first end 16 of the shaft 12. The lower section 82 of the spring 24 is positioned within the spring passage 86.

[0039] Reference Figures 9 to 10 shows details of a spring 24 according to an exemplary embodiment. A lower section 82 of the spring 24 includes a first length L1 defined between one end 83 and a longitudinal section 80. In various embodiments, L1 is less than a maximum length.

[0040] The spring 24 further includes a thickness T defined between opposite surfaces of the longitudinal section 80. In various embodiments, T is between 0.01 inches and 0.07 inches, specifically between 0.02 inches and 0.06 inches, more specifically between 0.03 inches and 0.05 inches. In a specific embodiment, T is about 0.044 inches (i.e., 0.044 inches plus or minus 0.01 inches).

[0041] The longitudinal section 80 of the spring 24 has a spring height H2 that is defined between an outer surface of the lower section 82 of the spring 24 and an outer surface of an upper section 78. In various embodiments, H2 is between 1 inch and 1.6 inches, specifically between 1.1 inches and 1.5 inches, more specifically between 1.2 inches and 1.4 inches. In a specific embodiment, H2 is about 1.38 inches (i.e., 1.38 inches plus or minus 0.05 inches). In various embodiments, L1 is less than 50% of H2.

[0042] The longitudinal section 80 of the spring 24 has a second spring height H3 that is defined between an inner surface of the lower section 82 of the spring 24 and an inner surface of the upper section 78. In various embodiments, H3 is between 80% and 99% of H2, specifically between 85% and 97% of H2, more specifically between 90% and 95% of H2. In such an embodiment, H3 is about 93% of H1 (i.e., 93% plus or minus 2%).

[0043] As previously described, the height of the spring 24 is relatively long compared to the height of a conventional fixed component with respect to the height of the shaft 12. In various embodiments, H2 is greater than 20% of H1. In various embodiments, H2 is between 20% and 40% of H1, specifically between 25% and 35% of H1, more specifically between 29% and 32% of H1. In such an embodiment, H2 is about 31% of H1 (i.e., 31% plus or minus 0.5%).

[0044] The upper section 78 of the spring 24 includes a second length L2 defined between one end 85 and the longitudinal section 80. In various embodiments, L2 is less than L1. In various specific embodiments, L2 is less than 50% of L1. In various embodiments, L2 is less than a maximum length.

[0045] After the spring 24 is installed in the first end 16 of the shaft 12 and / or the tool bit holder 39, a punch is used to deform the spring 24. Specifically, the punch applies a force to the lower section 82 of the spring 24 to deform the lower section 82, thereby fixing the spring 24 in place. In other words, when the spring 24 is positioned within the slot 22, the outer portion or surface of the spring 24 is deformed to secure the spring 22 to the shaft 12. As Figure 10 shown, once the lower section 82 is deformed, the deformed lower section 82a does not extend from the longitudinal section 80 in a completely vertical or horizontal orientation. Due to the deformed section 89 of the lower section 82a, the spring 24 resists removal from the tool bit holder 39, and the spring 24 is securely mounted at the first end 16 of the shaft 12. In other words, if a user attempts to remove the spring 24 from the tool bit holder 39, the deformed section 89 engages the spring channel 86 to provide resistance.

[0046] The deformed lower section 82a of the spring 24 includes a third length L3 defined between one end 83 and the longitudinal section 80. In various different embodiments, L3 is between 0.1 inches and 1 inch, specifically between 0.2 inches and 0.8 inches, and more specifically between 0.4 inches and 0.6 inches. In a specific embodiment, L3 is approximately 0.5 inches (i.e., 0.5 inches plus or minus 0.075 inches).

[0047] Reference Figure 11 , details of the tool bit 30 according to an exemplary embodiment are shown. In the illustrated embodiment, the wire-stripping tool bit 30 is reversible and includes two ends. The first end 90 of the wire-stripping tool bit 30 is a type 110 terminal, while the opposite second end 94 is a type 66 terminal. In various different other embodiments, the wire-stripping tool bit may have different terminal types. The central body portion 92 is positioned between the first end 90 and the second end 94 of the wire-stripping tool bit 30 and is connected to the first end and the second end of the wire-stripping tool bit. The central body portion 92 includes a slot 93 configured to engage the upper section 72 of the spring 24. In various different embodiments, the central body portion 92 includes two slots 93 such that the wire-stripping tool bit 30 can be positioned with either side of the central body portion 92 facing the spring 24.

[0048] When the spring 24 is installed in the tool bit holder 39, the upper section 72 of the spring extends through the wall of the tool bit holder 39, where the spring end 85 extends freely into the first recess 40. When the wire-stripping tool bit 30 is positioned within the first recess 40, the upper section 72 is aligned with and engages the slot 93. Then, the wire-stripping tool bit 30 is rotated within the first recess 40 to fix the wire-stripping tool bit 30 relative to the shaft 12.

[0049] Reference Figure 12, a detailed perspective view of the first end 116 of the multi-purpose tool 100 according to another exemplary embodiment is shown. Except for the differences discussed herein, the multi-purpose tool 100 is substantially the same as the multi-purpose tool 10. The punch is used to deform a longitudinal section 180 of the spring 124 and a portion of the shaft 112, rather than using the punch to fix the lower section 82 of the spring 24. Specifically, the punch applies a force to the longitudinal section 180 of the spring 124 to fix the spring 124 in place within the slot 122 and relative to the shaft 112. The deformed section 190 of the spring 124 is positioned along the longitudinal section 180 of the spring 124.

[0050] The position of the deformed section 190 (i.e., the position where the force is applied) is selected to provide a desired spring force to the spring 124. The spring force is determined by the cantilever distance D. As is generally understood, selecting a smaller cantilever distance will provide a greater spring force. The cantilever distance D is defined between the upper section 178 of the spring 124 and the center 192 of the deformed section 190. In a specific embodiment, D is selected to be half of the first height of the longitudinal section 180. In such an embodiment, the spring force is greater than the minimum force. In other embodiments, D is selected to be a different distance.

[0051] In various different specific embodiments, D is between 1% and 99% of H2, specifically between 30% and 80% of H2, more specifically between 40% and 70% of H2. In such an embodiment, D is approximately 50% of H2 (i.e., 50% plus or minus 5%).
