3 Claims. l

My invention relates to coaxial cable connections and more particularly to means for establishing permanent connections for coaxial cables.

Hitherto such cable connections have been the separable type involving threaded parts, many of which required soldering to the conductors of the cables. Such connections are bulky, expensive and difficult to install. The use of solder may cause injury to the inner insulation and may necessitate the deposition of large amounts of metal on the outer conductor, thereby changing the electrical characteristics of the cable.

The principal object of my invention is to provide an indentable type of connection for coaxial cables which will not appreciably change the electrical characteristics of the cable.

Other objects are to provide a connection which will not require heat; which will not add appreciably to the diameter of the cable; which is inexpensive to install; requires little bulk or weight; and which can be manufactured at low cost.

I accomplish these and other objects and obtain my new results as will be apparent from the device described in the following specifica- 25 tion, particularly pointed out in the claims, and illustrated in the accompanying drawing in which:

Fig. 1 is an exploded perspective view of my device for terminal connections;

Fig. 2 is a longitudinally sectioned assembly view for coaxial cables showing the nal connection;

Fig. 3 is an exploded perspective View of the elements of my device for making a splicing connection for coaxial cables;

Fig. 4 is a longitudinal sectioned assembly view showing the iinal splice connection.

In the drawing, reference numeral I designates a portion of coaxial cable having a central conductor II, an intermediate insulator I2, the tubular conductor I3, and the outer insulation Il.

In order to provide my novel terminal connection, I provide an inner ferrule I5, and outer ferrule I6, a central conductor terminal I1 and an outer conductor connection I8.

The central conductor terminal I1 comprises a tubular body section Ila, an insulation shroud I'Ib and a terminal lug IIc, all of which may be made from a single piece of metal tubing formed into the desired shape.

The outer connection I8 comprises a piece of ilexible conductor I8a which has been inserted into a tubular connector I8b having a conductor carrying body portion I8c for inserting the con- Ioi. 174-88) ductor I 8a therein, which connector I8b terminates in a terminal lug I8d. The connector I8b may also be made of a single piece of metal tubing formed into the desired shape, with the 5 body portion I8c indented as at I8e to secure the conductor I8a thereto.

The various elements are assembled in the following manner: The cable is stripped to expose a suiilcient length of the central conductor suit- 10 able for insertion into the tubular body of the terminal I'I. The tubular conductor I3 is then bared and cut back for a short distance as shown in Fig. 1.

The outer ferrule I6 is then inserted over the tubular conductor I 3 until it is adjacent the outer insulation and over the ends of conductor I8a which is compressed thereunder. The inner ferrule I5 is then inserted under the marginal edge of the tubular conductor until hidden from View.

Thereafter the outer ferrule I6 with the end of conductor I8a thereunder is slid until directly over the inner ferrule I5. A circumferential crimp IEa locks the conductors I3 and I8a to the ferrules I5 and I6.

The terminal connector I1 is then inserted over uthe end of the central conductor Il, with the shroud IIb covering a portion of the insulation I2. The tubular body section I'Ia and the shroud I'Ib are suitably indented as at I'Idand crimped as at IIe, respectively, to secure the terminal thereto.

The completed assembly of the connection is shown in section in Fig. 2.

In providing a splice connection, I employ the construction shown in Figs. 3 and 4. The elements include the coaxial cables 20 and 2|, the

vpair of inner ferrules 22 and 23, an outer connection ferrule 24 and an inner connecting ferrule 25.

Cables 20 and 2l each contain central conductors 26 and 21, tubular conductors 28 and 29, intermediate insulation 30 and 3|, and outer insulation 32 and 33, respectively.

The cable ends 20 and 2l are prepared similarly as indicated for terminal connections.

The inner ferrules 22 and 23 are slipped under the tubular conductors 28 and 29, as previously described. Thereafter the outer ferrule 24 is 5o placed over one cable end and pushed to one side to expose the inner conductor. The inner ferrule 25 is then connected to the inner cable ends 25 and 21 and indented thereto as at 34 and 35. The outer ferrule'is pulled back into position so that the two ends thereof are positioned over the inner ferrules with the tubular conductors inbetween.

circumferential crimps 38 and 31 are applied to the ends thereof to secure the outer ferrule 24 into electrical and mechanical engagement with the tubular cable conductors. The assembled view is shown in Fig. 4. The outer conductors I3 and 28 are preferably of the braided type which may be stripped from the insulation without damage to either, in order that the inner ferrules may be inserted thereunder. The inner ferrules support the crimping pressures and prevent .the insulation from being crushed and insure a good electrical contact with the braided conductor and the outer ferrule.

Tools for performing the indenting and crimping operation are illustrated in pending applications Serial No. 510,426, now abandoned,A and Serial No. 563,029, now Patent No. 2,457,538, issued December 28, 1948, respectively.

I have thus described my invention, but I desire it understood that it is not confined to -the particular forms or uses shown and described, the same being merely illustrative. and that the invention may be carried out in other ways without departing from the spirit of my invention, and, therefore, I claim broadly the right to employ all equivalent instrumentalities coming within the scope of the appended claims, and by means of which, objects of my invention are attained and new results accomplished, as it is obvious that the particular embodiments hereinV separated at one end thereof from the layer of insulating material, an inner conductor sleeve having a tubular end made of metal attached to the end of the inner conductor, to permit transmitting current therefrom, said inner conductor sleeve having means at the remaining end for electrical attachment to another conductor, a rigid inner tubular ferrule made of non-collapsible metal positioned within the separated portion of the outer conductor and encircling the inner conductor, an outer ferrule made of crimp.A

able metal encircling the outer conductor and positioned directly above the inner tubular ferrule, said outer ferrule being crimped to the inner tubular ferrule with the outer conductor being positioned therebetween, and extending means for electrically connecting the outer ferrule to another conductor.

2. A connection for transmitting current, comprising a coaxial cable having inner and outer conductors spaced apart by a layer of insulating material, the outer conductor made of hollow readily expansible stranded and braided metal separated at one end thereof from the layer of insulating material, an inner conductor sleeve having a tubular'end made oi metal attached to the end of the inner conductor, to permit transmitting current therefrom, said inner 'conductor sleeve terminating in a connecting lug section. a rigid inner tubular ferrule made of non-collapsible metal positioned within the separated portion of the outer conductor and encircling the inner conductor, an outer ferrule made of crimlpable metal encircling the outer conductor and positioned directly above the inner tubular ferrule, said outer ferrule being crimpedI to the inner tubular ferrule with the outer conductor positioned therebetween, and a terminal conductor positioned between the outer conductor and the outer ferrule.

3. A connection for splicing electrical coaxialI cables, said coaxial cables having inner and outer conductors spaced apart by a layer of insulating material, the outer conductors made of hollow readily expansible stranded and braided metal separated at oneend thereof from the layer of insulating material, an inner hollow metal conductor sleeve receiving the adjacent ends of the inner conductor and indented thereto, a rigid inner tubular ferrule made of non-collapsible metal 'positioned Within the separated portion of each of the outer conductors and encircling the inner conductors, an outer ferrule made of crimpable metal extending between and encircling the outer conductors and .positioned directly above the inner tubular'ferrules, said outer ferrule being crimped to the inner tubular ferrules with the outer conductors being positioned therebetween.
