Abstract
A wire connector fastening tool comprises an elongate body having a first end, a second end, an outer hand-engaging surface and an interior surface. The outer hand-engaging surface has a generally uniform outside diameter from its first end to its second end. The interior surface defines an internal axial bore extending through the body from the first end to the second end. The axial bore has a first section with a first inside diameter and a second section with a second inside diameter. The second inside diameter is larger than the first inside diameter. The first section of the bore extends from the first end of the body to a point between the first and second ends of the body. The second section of the bore extends from the first section of the bore to the second end of the body. The first end of the body is adapted to engage with at least a portion of the first wire connector in a manner so that rotation of the body causes rotation of the first wire connector. The second end of the body is adapted to engage with at least a portion of a larger second wire connector in a manner so that rotation of the body causes rotation of the second wire connector. The internal axial bore is adapted to receive a pigtail or extension wire that extends beyond other electrical wires received in the wire connector. The pigtails and extension wires may be used for device terminations, and may be used as extensions for connecting the circuit to other circuits or electrical devices.
Description
- The present invention relates to wire connector fastening tools and drivers. More particularly, the present invention relates to tools used for attaching a wire connector to a plurality of electrical wires for electrically connecting conductive ends of the electrical wires to one another. Even more particularly, the present invention relates to a wire connector fastening tool that is easy to manufacture and use, and which is capable of receiving a variety of sizes and shapes of wire connectors.
- Wire connectors are used to electrically connect exposed conductive ends of two or more electrical wires together. In recent years, the use of such wire connectors has become very popular in the installation of lighting fixtures, ceiling fans, electrical switches and electrical outlets, because they are relatively inexpensive and easier to use than prior art methods of connecting electrical wires, such as soldering.
- In general, conventional wire connectors comprise an outer cap portion of non-conductive material (e.g., plastic) and a tapered insert of conductive material (e.g., metal) carried within the cap. The cap is provided with an open lower end that permits access to the conductive insert. Typically, the insert includes an internally threaded socket adapted to receive the exposed conductive ends of two or more electrical wires that are to be conductively connected. In use, the exposed conductive ends of two or more electrical wires are aligned with one another and inserted into the open end of the wire connector. The user then uses his or her fingers to manually twist or screw the wire connector onto the ends of the wires until the internally threaded socket of the conductive metal insert tightly engages the conductive ends of the wires to conductively connect them to one another and to secure the wire connector to the wires. The non-conductive cap of the wire connector insulates the exposed portions of the connected electrical wires from contacting other wires or other conductive portions of the fixture. In many conventional wire connectors, the upper end of the wire connector includes an aperture that is adapted to receive a wire pigtail or other wire extension (e.g., a ground wire, a hot leg, or a neutral conductor) that is to be passed through the upper end of the cap.
- Such conventional wire connectors come in a variety of shapes and sizes. One type of conventional wire connector has a generally conical or frustoconical shape with a ribbed outer surface that facilitates manual twisting or screwing of the wire connector. See FIG. 5, which is discussed more fully below. Another type of conventional wire connector has a generally tapered body portion with a pair of outwardly extending “wings” or fins disposed on opposite sides of the body portion to make it easier for the user to manually twist or screw the wire connector onto the ends of the wires.
- A problem with manually twisting or screwing conventional wire connectors onto wires is that the user's fingers and thumb can become sore from engagement with the ribs and wings of the nuts, particularly after installing a large number of them. To avoid this problem, various prior art wrenches, pliers and other tools have been developed for installing wire connectors. However, these prior art devices have proven to be heavy and cumbersome, difficult to use, or altogether ineffective. Thus, a need exists for a wire connector fastening tool that facilitates manual installation of wire connectors, yet is lighter, more compact and easier to use than prior art tools.
- Another problem with prior art wire connector fastening tools is that they do not provide an effective means for receiving a wire pigtail or other wire extension (e.g., a ground wire, a hot leg, or a neutral conductor) that passes through the upper end of the cap or for receiving a ready made pigtail attached to the wire connector itself. Thus, a need exists for a wire connector fastening tool that does provide a means for receiving a wire pigtail or other wire extension extending from the top of the wire connector.
- A general object of the invention is to provide a wire connector fastening tool that is simple in construction and inexpensive to manufacture, yet capable of receiving a variety of sizes and shapes of wire connectors. Another object of the invention is to provide a wire connector fastening tool that is easier to use than prior art wire connector fastening tools and drivers. Still another object of the invention is to provide a wire connector fastening tool that is made entirely of nonconductive materials and that is sized to fit easily on one's pocket when not in use. A more specific object of the invention is to provide a wire connector fastening tool having an axial passageway that is shaped and adapted to receive and isolate a wire pigtail or other wire extension (e.g., a ground wire, a hot leg, or a neutral conductor) that is to be passed through the upper end of the cap of the wire connector.
- In general, a wire connector fastening tool of the present invention comprises an elongate body having a first end, a second end, and an outer hand-engaging surface. The outer surface has a generally uniform outside diameter from the first end of the body to the second end of the body. The body comprises first and second sections having first and second axial bores, respectively. The first axial bore has a first inside diameter that extends from the first end of the body to a point between the first and second ends of the body. The second axial bore has a second inside diameter that is larger than the first inside diameter. The second axial bore extends from the first axial bore to the second end of the body. The first and second axial bores are in communication with one another to define an internal passage that extends through the body from the first end to the second end. The first end of the body is adapted to receive a portion of the wire connector with an outside diameter less than or equal to the first inside diameter.

As explained below, thenotches - As best shown in FIGS. 1, 3 and4, the outer hand-engaging
surface 16 of thetool 10 includes a plurality of circumferentially-spaced, longitudinal recesses or “flutes” 26, which are intended to enhance a user's grip of thetool 10 during use of thetool 10 by facilitating rotation of thetool 10 about an axis that is co-linear with the first and second internalaxial bores first end 12 to thesecond end 14 of the body, so that the cross-sectional shape of theouter surface 16 of the body is uniform from thefirst end 12 of the body to thesecond end 14. - In the preferred embodiment, the body is of a non-conductive material, such as a polymeric material. Preferably, the entire wire
connector fastening tool 10 is of a single monolithic piece of polymeric material. Also, preferably, at least a portion of the body of thetool 10 is of a substantially transparent or translucent polymeric material that permits a visual inspection of the interiors of the first and secondaxial bores tool 10. - FIG. 5 is an illustration of a
conventional wire connector 50 having a generally conical or frustoconical shape. Thewire connector 50 has an outer cap portion of non-conductive material (e.g., plastic). The outer cap portion has a generally conical or frustoconicalouter surface 52 that extends from a generally closedupper end 51 to a generally openlower end 53. Theouter surface 52 includes a plurality of ribs defined by a plurality of circumferentially-spaced,longitudinal recesses 54, which facilitate manual twisting or screwing of thewire connector 50. The ribs also enhance a frictional engagement between theouter surface 52 of thewire connector 50 and the interior surfaces of the first and secondaxial bores tool 10 when received therein. Thewire connector 50 also includes a tapered insert (not shown) of conductive material (e.g., metal). The generally openlower end 53 permits access to the conductive insert. The conductive insert includes an internally threaded socket (not shown) adapted to receive the exposed conductive ends of two or more electrical wires that are to be conductively connected by thewire connector 50. As shown in FIG. 5, theupper end 51 of thewire connector 50 includes anaperture 56 that is adapted to receive a wire pigtail or other wire extension (e.g., a ground wire, a hot leg, or a neutral conductor). Theaperture 56 allows the pigtail or extension to pass through theupper end 51 of thewire connector 50. - FIGS. 6 and 7 are illustrations of a conventional wingnut-
type wire connector 60 having a generally taperedbody portion 62 that extends from a generally closedupper end 61 to a generally openlower end 63. A pair of outwardly extending “wings” orfins 64 are disposed on opposite sides of thebody portion 62. Thesewings 64 facilitate manual twisting or screwing of thewire connector 60. Also, as explained below, thewings 64 are adapted to be received in thenotches tool 10 when thewire connector 60 is received in one of the first and second ends 12 and 14 of thetool 10 to facilitate in the rotation of thewire connector 60 by thetool 10. As shown in FIG. 7, thewire connector 60 includes a taperedinsert 68 of conductive material (e.g., metal). The generally openlower end 63 permits access to theconductive insert 68. Theconductive insert 68 includes a taperedsocket 70, which is preferably internally threaded. Thesocket 70 is adapted to receive the exposed conductive ends of two or more electrical wires that are to be conductively connected by thewire connector 60. Theupper end 61 of thewire connector 60 includes anaperture 66 that is adapted to receive a wire pigtail or other wire extension 84 (e.g., a ground wire, a hot leg, or a neutral conductor). Theaperture 66 allows the wire pigtail orextension 84 to pass through theupper end 61 of the wire connector 60 (refer to FIG. 9 and the corresponding discussion below). - Thus, the wire
connector fastening tool 10 of the present invention can be used to safely and efficiently connect a plurality of electrical wires to one another with a wire connector. In use, a portion of a wire connector (such as those illustrated in FIGS. 5-7) is inserted, closed end first, into one of the first and second ends 12 and 14 of thetool 10. Preferably, the wire connector is inserted until it fits rather snugly, to ensure an efficient frictional engagement that permits rotational movement of thetool 10 about an axis co-linear with the internalaxial bores wire connector 60 shown in FIGS. 6 and 7, thewings 64 are received in thenotches first end 12 when thewire connector 60 is received in the firstaxial bore 22 or in thenotches second end 14 when thewire connector 60 is received in the secondaxial bore 24. The portions of the body defining the notches engage thewings 64 in a manner so that rotational movement of thetool 10 about an axis co-linear with the internalaxial bores wire connector 60. As explained above, the inside diameters of the first and secondaxial bores - FIG. 9 is a sectional view of the wire
connector fastening tool 10 holding a wingnut-type wire connector 60 in thesecond end 14 of thetool 10. Once a portion of a wire connector is received in one of the first and second ends 12 and 14 of thetool 10 in this manner, exposed conductive ends ofelectrical wires 80 to be connected to one another are aligned with one another and then inserted into the openlower end 63 of thewire connector 60 and into the wire-connectingsocket 70. Then, the user rotates thetool 10 about an axis that is co-linear with the internalaxial bores wire connector 60 relative to thewires 80, until theconductive insert 68 tightly engages the conductive ends of thewires 80 to conductively connect them to one another and to secure thewire connector 60 to thewires 80. The non-conductive outer cap portion of thewire connector 60 insulates the exposed portions of the connectedelectrical wires 80 from contacting other wires or other conductive portions of the fixture. - As shown in FIG. 9, in the case of wire connectors having an upper end with an aperture, a wire pigtail or other wire extension84 (e.g., a ground wire, a hot leg, or a neutral conductor) may be passed through the aperture of the wire connector, and then inserted into one or both of the first and second internal
axial bores tool 10. As explained above, the first and second internalaxial bores tool 10. Accordingly, the pigtail orextension 84 can be passed through the first and second internalaxial bores tool 10, and beyond. Because the first and second internalaxial bores tool 10, thetool 10 can accommodate a pigtail orextension wire 84 of any length. Thus, as shown in FIG. 9, when a wire connector is received in one of the first and second ends 12 and 14 of thetool 10, the pigtail orextension wire 84 can be passed through the aperture in the upper end of the wire connector and through the first and secondaxial bores extension wire 84 to extend beyond the otherelectrical wires 80 received in the lower end of the wire connector during use of thetool 10, regardless of the length of theextension wire 84. Such pigtails and extension wires may be used for device terminations, and may be used as extensions for connecting the circuit to other circuits or electrical devices. The pigtails and extension wires may or may not be conductively connected to the otherelectrical wires 80 received in the lower end of the wire connector. - Because the entire body of the
tool 10 is preferably of a transparent or translucent polymeric material, the user can easily see the wire connectors and wires received within the tool to ensure that they are in their proper positions during use of the tool. - A significant benefit of the wire
connector fastening tool 10 of the present invention is the simplicity of its design, which results in low material and manufacturing costs. First, polymeric materials are relatively inexpensive, lightweight, easy to mold and machine, and available in transparent and translucent compositions. Second, the uniform cross-sectional shape of the body (which resembles a conventional screwdriver handle) permits extrusion of the body, if desired. Alternatively, the body could be formed in molding and/or machining processes. The body of thetool 10 can be extruded and then cut to a desired length. Because polymeric materials are so easy to machine, the first and secondaxial bores notches - Thus, a preferred method of making a wire
connector fastening tool 10 of the present invention comprises the steps of: extruding or otherwise forming the elongate monolithic body; cutting the extruded body to length so that the body has afirst end 12, asecond end 14, and anouter surface 16 between the first and second ends; boring or otherwise forming a first internal axial bore 22 with a first inside diameter that extends from thefirst end 12 of the body to a point between the first and second ends of the body; boring or otherwise forming a second internal axial bore 24 with a larger second inside diameter that extends from the second end of thebody 14 to the first axial bore; cutting or otherwise forming at least twonotches first end 12 of the body; and cutting or otherwise forming at least twonotches second end 14 of the body. - While the present invention has been described by reference to specific embodiments and specific uses, it should be understood that other configurations could be constructed and other uses could be made without departing from the scope of the invention as set forth in the following claims.
