Abstract
Description
- This application claims priority of my Provisional Application No. 60/761,825 filed Jan. 26, 2006.
- The field of this invention is tools for the electrical communications industry.
- When installing insulated electrical wires into Insulation Displacement type electrical Connectors (IDCs) it has been a standard practice to use a wire insertion tool blade for pushing the insulated wire down between the pair of knives of the connector. My U.S. Pat. No. 7,096,564 issued Aug. 29, 2006 shows the manner in which the tool blade controls the insertion of an insulated wire into an insulation displacement type electrical connector. The knives then cut through the insulation to make an electrical connection. The wire insert tool blade typically also includes a cutting edge for cutting off a protruding end portion of the wire after it has been inserted, if the wire is to then become electrically terminated at that particular connector.
- In the communications industry such wire insert tool blades are commonly referred to as either a 110 Blade, or a 66 Blade, depending upon the type of electrical panel where the installation is being made. One example of a 110 tool blade is shown in my U.S. Pat. No. 7,096,564 issued Aug. 29, 2006. An example of a combination 66-110 blade is shown in my Pat. No. Des. 412,431.
- Such tool blades are commonly mounted in or upon a punch-down or impact tool, also known as a bayonet type impact tool, which when activated applies a driving impact in a forward direction to the tool blade. The presently standard punch-down tools when activated develop a fixed amount of driving force or impact. However, in my U.S. patent application Ser. No. 11/175,466 filed Jul. 5, 2005, I have shown a low-impact kind of punch-down tool for which the downward driving force can be precisely adjusted or controlled by the operator.
- Not only may such punch-down tools need adjustment or control of their driving force, but a further requirement for such tools is convenience for the user. As the connector board technology has progressed the connectors have become more and more crowded and have become difficult to work with.
- The electrician or tradesman needs not only adequate working space for manipulating or controlling the tool assembly, but also equally needs adequate visibility of the location where the result of the work takes place. The nature of both those requirements varies somewhat depending upon the type of electrical panel, the type of punch-down tool, and other factors.
- According to the present invention I have determined that an extension device inserted between a punch-down or impact tool and a wire insert blade that is driven by the tool has unexpected benefits for the electrician or tradesman. Not only does it become easier for the tradesman to place the wire insertion blade between the connector knives, but visibility of the work being done is greatly improved, ensuring greater efficiency of the tradesman's work and better performance of the resulting installed product. Also, by the use of this new tool the safety of the technician is improved. The technician can operate a punch-down quite some distance away from the wire termination. The technician is kept away from possible charged electric wires or dark areas where insects may reside, and can clearly view the wires he will be connecting and increasing his stand-off for better focus of his eyes.

FIG. 1 including separate views 1 a, 1 b, 1 c, 1 d, 1 e, and 1 f is a perspective view of a tool system including a punch-down tool together with my unique tool extension device, and showing how either a 110 blade or a 66 blade may be selectively supported from the tool extension device; -
FIG. 2 a is a perspective view, showing how the upper end of my tool extension device fits into the hollow lower end of a punch-down tool; -
FIG. 2 b is a perspective view of my tool extension device showing both its male upper end and female lower end; and -
FIG. 2 c is a fragmentary cross-sectional view showing how the slot and detent of the male connection end of either the extension device or the wire insert tool fits into a hollow female connection on the punch-down tool or extension device, and is locked in place by the associated spring. - As shown in the drawings, a
tool system 10 for inserting aninsulated wire 12 into theknife blades 14 of an Insulation Displacement Connector (IDC) includes a punch-down tool 20 whose effective length is extended by use of mynovel extension device 30. A wireend insert tool 50 is then securely locked in the lower end of the extension device. A wire end insert tool of the 110 type is shown, for example, in my Pat. No. 7,096,564. - More specifically, the punch-down
tool 20 has a hollow cylindricallower driving end 22 with acircumferential groove 24 extending about its outer surface. At one point in groove 24 asingle hole 25 is formed through the groove wall. Alocking spring 26 is disposed within thecircumferential groove 24 and extends about most, but not all, of its circumferential length. Thespring 26 has an inturnedend 28 which extends through theradial hole 25 in order to perform a locking function. - The
tool extension device 30 is of elongated and generally tubular configuration, being about one and one half to four inches in length, but preferably about two and a half inches.Extension device 30 has anupper end portion 32 which has, on its exterior surface, alongitudinal slot 34. There is a sloped ramp 36 in the upper end ofslot 34. The ramp has a peak at about ¾ or ⅞ of its length. At the lower end of ramp 36 there is a depression 38 forming a detent which extends laterally. - The inturned
end 28 of thelocking spring 26 on the punch-downtool 20 normally projects through thehole 25 of punch-downtool 20. When the upper end ofextension device 30 is to be installed into the punch-downtool 20 the extension device is rotated until the inturnedend 28 oflocking spring 26 of punch-downtool 20 enters the upper end of ramp 36 on the extension device. Then the two parts are longitudinally moved together in a telescoping movement. After thespring end 28 passes the peak of ramp 36 and moves on down, it engages the depresssion or detent 38 and the two devices become locked together, both rotationally and longitudinally. - The
lower driving end 40 ofextension device 30 has a hollowcylindrical wall 42, and acircumferential groove 44 on its outer surface. A singleradial hole 45 is formed at one point in the wall ofcircumferential groove 44. Alocking spring 46 extends about most of the circumference oflower driving end 40, within thegroove 44, and has an in-turnedend 48 which normally extends throughhole 45 to provide a locking function. - A wire
end insert tool 50 of the 110 type has anupper end portion 52 with alongitudinal slot 54 formed in its exterior surface. The upper end ofslot 54 has a sloped ramp 56. A detent is formed in the laterally extending lower end portion 58 of ramp 56. - The inturned
end 48 of thelocking spring 46 on thetool extension device 30 normally projects through thehole 45. As indicated inFIGS. 1 d and 1 e, theupper end portion 52 of wireend insert tool 50 may be inserted into the hollowlower driving end 40 of thetool extension device 30. The parts are rotated so that inturnedend 48 of thelocking spring 46 on thetool extension device 30 may enter the upper end of ramp 56 on the insert tool. Then the two parts are longitudinally moved together in a telescoping movement. After thespring end 48 passes the peak of ramp 56 and moves on down, the wire insert blade engages the depresssion or detent 58, it is further rotated, and the two devices are then locked together, both rotationally and longitudinally. - ALIGNMENT. The extension device may be arranged, as shown, so that in the operative position of the tool system the cut side of the punch-down tool remains aligns with the cut side of the wire insert tool.
- Thus I have provided a tool system with an extended reach for selectively inserting an insulated wire between the knife blades of an insulation displacement type electrical connector. The tool system includes a punch-down tool with a hollow lower driving end which forms the female part of a mechanical connector. An extension device of generally tubular configuration is about one and one half to four inches in length and has an upper end portion which forms the male part of a mechanical connector. The upper end portion of the extension device may be inserted into the hollow lower driving end of the punch-down tool so as to lock the extension device both rotationally and longitudinally relative to the punch-down tool. The lower end portion of the extension device has a hollow lower driving end which forms the female part of a mechanical connector. A wire end insert tool has an upper end portion which forms the male part of a mechanical connector. The male connector of the wire end insert tool may be inserted into the female connector of the extension device to lock the wire end insert tool both rotationally and longitudinally relative to the punch-down tool. As shown in
FIGS. 1 e and 1 f, the tradesman may use either the 110 typewire insert tool 50 of the 66 typewire insert tool 60. - EASE OF USE. My improved tool system allows the electrician or tradesman a complete range of choice for his tools. He can conveniently carry two or more extension devices that are of differing lengths. When an extension device is not needed the tool may be disassembled by pulling the part longitudinally. In-turned wire ends can be pulled out of their respective radial holes. Then the wire insert tool can be re-connected to the punch-down tool. As shown in
FIGS. 1 e and 1 f, he may use either a type 110 blade (reference No. 50) or a type 66 blade (reference No. 60). - SAFETY. My improved tool system allows the tradesman or electrician to clear his view of the work area by positioning his physical body parts away from the termination. This improved tool system keeps his hands away from the electrical termiation and allows better vision of the work area by adding distance between the technician's eyes and the electrical termination on which he is working.
- ALTERNATE FORMS. While I have shown a simple basic form of my extension device, it is also possible to have an extension device in two parts fastened together on a screw thread, which could then be rotated to enlarge or reduce the length of the extension device. Other types of extension methods are ball detents, or telescoping mechanisms, some of which were shown in my Provisional Application. While my extension device is preferably made as an integral metal part, it is also possible to use a plastic material, either entirely or in conjunction with a metal part. Other modifications may be apparent to persons skilled in the art.
- SCOPE OF PROTECTION. While I have disclosed in detail the presently preferred embodiment of my invention, it be understood that the scope of my invention is defined only in the appended claims.
