UNIVERSAL G)ltOUND CLIP ASSEMBLX
This application claims priority under 35 U.S.C. ~li9(e) to provisional patent application serial number 60/110,043 filed November 26, 1998, the disclosure of which is incorporated herein by reference.
The present invention relates generally to devices and methods for implementing a ground connection between a conductor of a cable nc~essenger strand and a cable clamp.
In even greater particularity, the present invention is directed to a universal ground clip assembly comprising a unique ground clip that may be utilized with interchangeable messenger clamps which have jaws that are typically clamped over the insulation jacket of the cable messenger strand. The present invention also pertains to the method of installing the universal ground clip assembly.
~ack.Qrnund of t a ><nvention A multitude of approaches have been taken to address the problem of grounding a cable clamp to a cable messenger strand. Some approaches involve stripping the insulation from the messenger strand to efi'ect a ground connection using conventional grouxading techniques. for instance, once the insulation has been removed, a cable clamp is positioned around the strand, a ground wire is positioned in contact with the messenger strand conductor between the conductor and the strand, and the clamp is secured to the strand thus effecting the ground connection. Such conventional techniques, however, are time consumi~. Moreover, stripping of the insulation array be hazardous to personnel and can adversely affect the integrity of the cable and strand.
,Another approach for grounding a cable clamp to a cable messenger strand has focused on including teeth on the jaws of a ground clamp which are intended to pierce the insulation of the messenger strand in order to make the ground connection with the conductor. This specific type of ground clamp inchxding its multiple components is typically positioned around the messenger strand in an attempt to align the teeth so that they make adequate contact with the messenger strand conductor when the clamp is tightened. However, it is recognized that such approach is tedious. Combining the functions of clamping to the messenger strand and making a ground connection with the strand conductor requires precise positioning and securing of the clamp. Any misalignment could adversely affect the integrity of the support function itself and/or the grounding connection.
Accordingly, in view of the foregoing drawbacks with currently available cable clamps and grounding techniques, an improved clamping and grounding device assembly azrd method are needed to simplify installation procedures in the ~reld.
In accordance with the purposes of the invention as embodied and broadly described herein, the present invention addresses the above needs by providing a universal ground clip assembly whose primary object or purpose is to electrically connect interchangeable rrtessenger clamps to a cable messenger strand strung between utility poles.
The messenger strand typically includes an insulation jacket for insulating a conductor. In one embodiment of the present invention, the ground clip assembly comprises a grounding clip positioned over the insulation jacket of the messenger strand. The grounding clip includes a penetration means for penetrating the messenger strand insulation jacket and engaging the messenger strand conductor wherein compression of the grounding clip on the messeztger strand causes the penetration means to penetrate the insulation jacket thereby establishing an electrical connection with the messenger strand conductor. In addition, this erxabodiment of the clip asserxtbly includes a variety of interchangeable messenger clamp means, such as a ground or span clamp, capable of engaging the grounding cGp. Upon engagement, the interchangeable messenger clamp means establishes an electrical connection with the grounding clip. The interchangeable messenger clamp means may further include a ground connection means for electrically connecting the interchangeable messenger clamp means to a ground. During assembly and installation, the grounding clip is preferably positioned and compressed on the messenger strand prior to installation of the interchangeable messenger clamp zr,~eans. Moreover, the grounding clip preferably comprises a saddle clip having a generally U-shaped cross-section with opposing first and second side members. The penetration means may either comprise a pointed prong formed in at least one of the first and second side members or at least one pointed S prong formed in each of the first and second side members.
The present invention also addresses the above needs in another embodiment by providing a universal ground clip whose primary object or purpose is to establish electrical connection with a cable messenger strand strung between utility poles. Again, the messenger strand typically includes an insulation jacket for insulating a conductor. In this particular embodiment, the ground clip comprises a generally U-shaped saddle body having opposing first and second side members and a length suWcient to accommodate a variety of interchangeable messenger clamp means. The saddle body positioned over the insulation jacket of the messenger strand. The clip further includes a penetration means for penetrating the messenger strand insulation jacket and engaging the messenger strand conductor. Compression of the saddle body on the messenger strand causes the penetration means to penetrate the insulation jacket thereby establishing an electrical connection with the messenger strand conductor. Preferably, the saddle body is positioned and compressed on the messenger strand prior to instahation of the interchangeable clamp means while the penetration means comprises a pointed prong formed in at least one of the first and second side members or at least one pointed prong formed in each of the first and second side members.
Furthermore, the present invention addresses the above needs in another embodiment by providing a method for electrically connecting interchangeable messenger clamps to a cable messenger strand strung between utility poles wherein the messenger strand includes an insulation jacket for insulating a conductor. In a preferred embodiment, the method comprises the steps of: (a) forming a grounding clip out of sheet metal; {b) further fashioning the grounding clip to include a penetration means for penetrating the messenger strand insulation jacket and engaging the messenger strand conductor; (c) positioning the grounding clip over the insulation jacket of the messenger strand; (d) coz~npressing the grounding clip so as to cause the penetration means to penetrate the insulation jacket thereby establishing an electrical connection with the messenger strand conductor; and (e) selectively attaching interchangeable messenger clamp means to the grounding clip thereby establishing an electrical connection with the grounding clip.
Preferably, the step of compressing the grounding clip is accomplished using a conventional hand tool, such as a pair of plyers, and occurs prior to the step of selectively attaching interchangeable messenger clamp means. Also, the interchangeable messenger clamp means preferably comprises a ground or span clamp and may further include a ground connection means for electrically connecting the interchangeable messenger clamp means to a ground. As with the previous embodiments, the grounding clip preferably comprises a saddle clip having a generally U-shaped cross-section with first and second side members.
The penetration means may either comprise a pointed prong formed in at least one of the first and seco»d side members or at least one pointed prong formed in each of the f rst and second side members. These and other objects, features, and advantages of the present invention will become more fully apparent froze the following description az~d appended claims, or may be learned by the practice of the invention as set forth hereinafter.
