Definitions
- ABSTRACT A metal strip connector with a convex pronged 513-5211628, 629, 4 1 1 3 surface is inserted under the shielding of a cable, pulled for- 94 ward to cause the prongs to pierce the shielding and the free end folded back over the jacket and bound down, thus locking [56] References cued the prongs in their piercing position. The extreme free end of UNITED STATES PATENTS the connector is formed into a loop that is pressed onto the 2,099,950 1 1/1937 Whitehead et al 339/97 X flexible conductor of a harness.
- prongs project outwardly and are METHOD AND MEANS FOR CONNECTING CABLE SI'IIELDING BACKGROUND OF THE INVENTION
- cables such as that described in US. Pat. No. 3,459,877, assigned to the present assignee, in which the shielding bonds firmly to the jacket.
- the outer surface of the shielding is not available for making electrical connections, and conventional means for assuring shielding continuity when cables are joined cannot be employed.
- electrical connection to the cable shielding should be made, that it should have high electrical conductivity, be easy, inexpensive, and fast to install, and have long life and positive reliability during this life. It is highly desirable that connections should be made without special tools, other than those carried normally by telephone installation crews.
- My connector comprises a metal strip with a substantial curved portion extending from one end of the strip. This portion is curved across its short dimension and a fiat portion of the strip extends from the curved portion. A plurality of pointed toward the flat portion which comprises a closed conductor-receiving loop at the end remote from the curved portion.
- a bonding harness of my invention comprises a length of insulated conductor with bared portions at each end and one of the strip connectors of my invention compressed onto each of the ends of the conductor.
- FIG. I shows a perspective view of a strip connector of my invention.
- FIG. 2 shows a view, from the curved end, of the connector of FIG. 1.
- FIG. 3 shows a perspective view of a harness of my invention.
- FIGS. 4a4f show the steps of a method of my invention.
- a strip connector indicated generally by the numeral 10
- the curvature of the portion 13 which is curved across the dimension 11 can best be seen in FIG. 2.
- a double row of sharp pointed prongs 16 have been stamped into the portion 13 to project outwardly,
- the flat portion 14 constitutes a substantial fraction of the total dimension 12 extending from line 17 which marks the end of the curvature and a slight upward bend in the strip.
- the portion 14 terminates in a closed loop 18 large enough to receive a conducting strand.
- an end 19 of the loop 18 is folded around under an underface 21 of the connector 10, I have found that when a full loop 18 is formed no soldered seam to close the loop 18 is required although the loop can be soldered or brazed, at extra cost within the scope of my invention.
- Each of the prongs l6 terminates in a sharp point 23 directed outwardly and generally in the direction of the flat portion 14.
- a supply of the connectors 10 are prepared, and a harness, indicated generally by the numeral 25 (FIG. 3), is formed by pressing one of the connectors 10 to each end of an insulated stranded conductor 24 from which insulation 26 has been stripped from each end to expose bared conductor lengths 27, 28.
- the size of the metal strands forming the lengths 27, 28 is such that they fit easily into the loops 18 of the connectors but substantially fill these loops so that good and permanent electrical connections can be made by pressing the loops down upon the strands. This can be done with conventional tools.
- the metal used for connectors 10 must take a permanent deformation without cracking or becoming brittle and I have found that brass. which may be cadmium plated, is particularly suitable. Solder is not needed for the compressed connection since the compression of the closed loop 18 assures a good compression fit.
- the cable for which my connection is particularly adapted can be seen in FIG. 4d to be comprised of a plurality of insulated conductors 29 within an overall jacket 31 to which is internally bonded a shielding layer 32 of aluminum, copper or other suitable metal or combination. Because of the bonding of the shielding 32 to the jacket 31 to the outer surface of the shielding is not readily available for electrical contact.
- the jackets 31 and attached shielding 32 are stripped back to expose lengths 36, 37 of the conductors 29 (FIG. 4b). Thence the conductors 29 of the two cables are spliced in a known manner (FIG. 40), and (FIG.
- the portions 14 are then bound down over the cables by means of a plurality of turns 39 of adhesive tape as shown in FIG. 4/.
- a conventional splice enclosure can be applied over the entire splice or the whole connection can be taped in a conventional manner, not shown.
- a connection between two cables each comprising a plurality of insulated conductors, an overall jacket, and a metallic shielding layer bonded to said jacket, comprising:
- A. means splicing the conductors of one of said cables to the respective conductors of the other of said cables,
- At least two connectors comprising metal strips, each comprising a plurality of prongs distributed over at least a substantial portion of said strip, said portion, comprising said prongs of one of said strips, being inserted directly under said shielding layer of one of said cables, and said portion, comprising said prongs of another of strips, being inserted directly under said shielding layer of the other of said cables, said prongs piercing said shielding layers and making electrical contact therewith, portions of said strips being folded back over said jackets so as to grip the combined shielding layer and jacket of each of sat cables between the folded portions of said strips,
