CRIMPING TERMINAL FOR COAXIAL CABLE Filed Jan. 29, 1968 5A/////////////A Uk A INVENTOR LLOYD MANCINI United States Patent O 3,517,375 CRIMPING TERMINAL FOR COAXIAL CABLE Lloyd Mancini, New Cumberland, Pa., assignor to Berg Electronics, Inc., New Cumberland, Pa., a corporation of Pennsylvania Filed Jan. 29, 1968, Ser. No. 701,356 Int. Cl. H01r 17/18 U.S. Cl. 339-177 17 Claims ABSTRCT OF THE DISCLOSURE A crimp type terminal and method for forming an electrical connection with the cylindrical sleeve or shield of a coaxial cable. When crimped to a bared braided sleeve the terminal collapses a medial portion `thereof to form an annular collar. The terminal is crimped to the collar to establish an electrical connection.

BACKGROUND OF THE INVENTION Conventionally electrical connections are established with coaxial cable braid by means of a solder connection or by inserting a iirst crimping sleeve under an end of the braid, positioning a second crimping sleeve over the braid, and then crimping the sleeves together to sandwich the braid therebetween.

A solder connection with the braid requires removal of a portion of the braid `from the cable to form a pigtail for physical connection with a wire or terminal, following which the joint is soldered. This type of connection is time-consuming to make and often results in an imperfect electrical connection between the terminal and the braid. Likewise the concentric sleeve type connection is expensive in terms of labor cost since the sleeves are positioned manually on the cable and then crimped together. Examples of conventional electrical connections for Ibraid are shown in Manzi, Marsman & Brenner, Grounding Sheathed Cable, pp. 128-130, Electrical Manufacturing, December 1952.

SUMMARY OF THE INVENTION The invention relates to a crimp type terminal and method for establishing an electrical connection with a wrapped or braided sleeve. The terminal is applied to a bared portion of the sleeve so that it grips the sleeve at spaced locations and is then collapsed axially to collapse the medial portion of the sleeve and form an outwardly projecting double thickness collar of sleeve material. A portion of the collapsed terminal is crimped to each side of the collar to establish the electrical connection. The terminal may be provided with a contact portion for establishing anelectrical connection with a circuit element.

The crimping terminal according to the invention is easily and quickly applied to the sleeve and forms a reliable electrical connection therewith without the necessity of manual assembly or a soldering operation. When the terminal is used to establish an electrical connection with the sleeve at an end of the coaxial cable, the free end of the sleeve is moved axially away from the end of the cable during attachment of the terminal so as to prevent accidental short circuiting between the axial conductor and the sleeve.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Elongate U-shaped crimping terminal 10 is formed from sheet metal stock and includes a pair of spaced U-shaped crimping barrels 12 and 14 joined together by a plurality of outwardly bent leg portions 16 which are spaced around the periphery of the terminal. Axially opposed contact ilanges 18 extend outwardly of the adjacent edges of barrels 12 and 14 and are inclined toward each other to improve contact with the braid. Braid gripping teeth 20 are provided on the interior surface of each barrel 12 and 14 adjacent the leg portions 16. As indicated most clearly in FIG. 4, the teeth 20 have a braid gripping face 21 for preventing movement of the braid relative to the barrel during collapsing of the terminal. Teeth 20 may be formed from the metal stock of the barrels 12 and 14 by a punching operation which also forms recesses 22 on the outer surface of the barrels. A suitable contact means 23, such as a pin disconnect, may be provided in order to establish an electrical connection between the terminal 10 and a circuit element.

The terminal is useful in establishing an electrical connection with a bared portion of the shield or braided sleeve conductor conventionally used in a coaxially cable 24 of the type shown in FIG. 2, having an inner or axial conductor 26. A pair of dielectric spacers 28 are wound around the conductor 26 in the form of helixes to locate the conductor centrally within the bore of cylindrical insulator 30. Flexible sleeve or ground conductor 32 encases the insulator 30 so as to prevent external elds from affecting the si-gnal carried by cable 24. An outer insulating sheath 34 may be provided. Spacers 28 are used to locate the central conductor 26 accurately relative to the insulator 30 and sleeve 32 in order to maintain a desired impedance for the cable.

The sleeve 32 surrounds the dielectric material 30 rather loosely to permit ready bending of the cable. It may be woven from groups of exible conductor strands to form a loose mesh braid as shown in the drawings, or may be formed from flexible conductor strands which are wound around the dielectric insulator 30 to form a sheath. In the latter case it is desirable that the cable be provided with an outer insulator 34 to conline the wound conductor strands and prevent unraveling of the sleeve. The terminal described herein is effective in establishing an electrical connection with either a woven or Wound sleeve. While two forms of coaxial cable shielding have been disclosed, the invention is not limited by the type of sleeve to which the terminal is secured. The terminal may be used to establish an electrical connection with collapsible conductive cylindrical sleeves other than the two forms mentioned. While the invention is particularly useful in establishing an electrical connection with the outer conductor of a coaxial cable, it is not intended to be limited to that use. It can be used wherever it is desirable to form an electrical connection with a flexible sleeve conductor.

Because sleeve 32 is used as one of the two conductors of the coaxial cable 24, it is necessary to form an electrical connection with the sleeve at the end of the cable.

3 To establish a connection -between a terminal and the end of the conductive sleeve of cable 24, a portion of the insulation 34 is removed from the end of the cable 24 a distance slightly -greater than the length of the terminal 10. The terminal is then placed around the exposed braid of sleeve 32 and barrels 12 and 14 are crimped closely to a generally circular cross section so that the teeth 20 engage the braid and prevent movement of the braid relative to the barrels. The terminal is then secured to the cable as illustrated in FIG. 2.

After the terminal is crimped to braid 32, the bar- Iels 12 and 14 are moved together to collapse the interconnecting leg portions 16 and to collapse the medial portion 36 of the braid 32 located between barrels 12 and 14. As the barrels are moved together the sheath collapses to form a double thickness annular collar 38 `which is confined between opposite straight leg portions 40 of the legs 16. Before collapsing of the legs 16, portions 40 in each leg define an obtuse angle. When the terminal is fully collapsed as in FIG. 4, the portions 40 are generally parallel to each other and sandwich the collar 38 therebetween to establish an electrical connection.

Upon movement of the barrels 12 and 14 toward each other, the medial portion 36 of the cylindrical sleeve 32 is readily collapsed to form the double thickness collar 38. During collapsing of the terminal and sleeve the teeth 20 in each barrel 12 and 14 engage the sleeve and prevent it from slipping relative to the barrels so as to assure that the medial portion 36 is collapsed to form collar 38.

During collapsing of the terminal and sleeve the medial portion 36 is rst bowed outwardly of the cable so that as the inclined flanges 18 are brought together they engage the sleeve 32. With further collapsing of the terminal and sleeve, flanges 18 tightly sandwich the collar 38 and are bent back from their original position. The bending of the flanges 18 during collapsing of the terminal assures that the collar 38 is yconfined therebetween under spring tension and improves the electrical connection between the flanges and the collar. In the collapsed terminal 10, barrels 12 and 14 are held closely together by legs 16 so that the flanges 18 establish an electrical connection with the collar 38.

An electrical connection between the terminal 10 and the sleeve 32 is established at each of the leg portions 16 and at each adjacent pair of flanges 18. As shown in FIG. 5, the flanges and legs of the terminal are spaced around the circumference of the cable 24 so that the terminal forms an electrical connection with the sleeve around essentially its entire circumferential extent. This is an important feature since it is desirable that the entire sleeve fonm part of the circuit in order to attain desired impedance and shielding. If a single connection is established with one circumferential portion of the sleeve, there is no assurance that the connection will place the entire sleeve at the same potential since the sleeve comprises a plurality of conductors which are not directly connected to one another. Terminal 10 insures that a reliable electrical connection is established with essentially all of the conductors in sleeve 32.

Because the electrical contacts between the sleeve 32 and terminal 10 are formed in a radial plane and the contact forces establishing these connections are essentially axial, the radial geometry of the cable 24 is not substantially distorted by. the attachment of the terminal to the cable. In this way the terminal 10 affects the impedance of the cable 24 to a minimum extent. When the terminal is crimped to the cable the opposing edges 42 of the barrels 12 and 14 are brought into contact to assure that teeth 20 rmly seat in the sleeve 32. When the crimping force is removed, the barrels relax slightly and the edges 42 separate to a slight degree. Crimping of the terminal on the cable results in a slight compression of dielectric insulator 30 as indicated in FIG. 4. Such distortion does not result in appreciable changes in impedance. In conventional crimp type connectors for establishing contact with the sleeve of a coaxial cable, :the electrical connection is formed as the result of a radial force likely to greatly distort the geometry of the cable and change the impedance of the cable.

As the terminal is collapsed the free end 44 of sleeve 32 is moved axially away from the free end of the cable 24 as a result of the shortening of the sleeve when the collar 38 is formed. By moving the sleeve 32 away from the end of the cable, the likelihood of short circuits occurring between the sleeve and axial conductor 26 is reduced. This feature of the invention is important since it eliminates the necessity of checking each terminal when attached to a braid to be certain that there is no accidental short circuiting between the sleeve and the central conductor as a result of unraveling of the sleeve.

FIG. -6 illustrates a terminal 50 comprising an arcuate U-shaped crimping 4'barrel 52 with a portion 54 extending therefrom. The barrel 52 may be tted over a part of an annular collar 56 formed in a conductive sleeve 58 of coaxial cable 60. The barrel 52 is then crimped to bring side or leg portions 62 thereof into intimate contact with the collar to establish an electrical connection therewith. A circuit element may be attached to a contact on portion 54.

Terminal 50 is mounted directly on the annular collar 56 formed in the sleeve of cable 60 and does not touch the body of the cable. Thus terminals 50 may be used in situations where it is highly desirable that the impedance of the cable not be affected at all by terminals secured to the conductive sheath.
