W/u MM 4. BRUNO sembled with a second connector member,

Patented Sept. 22, 1942 Bruno, Astoria, Long Island, N. Y., ls-

signor. by mesne assignments, to Bruno Patents tion of New York Inc., Long Island City, N. Y

Application August 1:, mt, Serial No. :sasai 2 Claims. (Cl. 174-22) This invention relates in coupling means for single conductor shielded cables, and more particularly to coupling means for co-axial cables.

It is a well known fact that cables ofthe above mentioned type are difilcult to handle, and, at times, must be cut in short lengths in order to pass through the regular paths. Therefore, an installation requiring this type of cable could be greatly simplified, and facilitated by the use of convenient and eflective coupling accessories by means of which co-axial cables can be easily connectedand disconnected.

One object of my invention is to provide coupling means for co-axial cables, which can be easily and quickly connected and disconnected, and arecapable of providing electrical and gaseous continuity in the cable thereby rendering all electrical connections air-tight, while maintaining gas communication within the cables.

Another object of my invention is to provide friction and constrictive electrical contacts, and

to produce such contacts for the inner .and/or outer conductor of the cable.

A further. obiect'of my invention is to provide a coupling mean for shielded cables, which can be easily fastened on 'the cable, and simultaneously forms electrical connection with the outer conductor.

It is also an object of my invention to provide a coupling means for electrical cables, in which electrical connection is eflected by friction and clamping contact of contact members simultaneously.

Other objects and advantages will become apparent from the specification, taken in connection with the accompanying drawing.

Fig.- l is a sectional view of one embodiment of my invention illustrating a first connector member fastened at the end of a co-axia1 cable, as-

the latter being partly broken away;

Fig. 2 is a sectional view of the second connector member shown in Fig. 1.

Referring to Fig. l, the co-axial cable I shown therein in section, may .be of the solid copper tubing type, the braided type or any other form trode of the cable, 8, I are spacing insulating washers, I is a first connecter member, 5 is the 1 member.

corresponding annular recess I! of the second connecter element shown in Figs. 1 and 2. This annular recess is formed by. an inner cylindrical surface of the second connecter member and the outer cylindrical surface of an insulating member positioned in said second connecter An air-tight joint may be produced by means of a rubber gasket 8, once the nut i is screwed over the corresponding connecter part.

In order to connect the first connecter member 4 shown in Fig.1 to an end of ace-axial cable, it is necessary to remove the cotton braid cover, if this is present, for about 7 from the end, for example, thus exposing the conductor braid or solid copper tubing which forms the outer conductor of the cable. The center conductor tube iscut so as to protrude about V from the extremity of the cable. Connecter member 4 is now made to slide over the end of the cable I to which the connecter is to be fastened, far enough to allow the exposed outer conductor to protrude just beyond the smaller diameter hole in connecter member I. When this has been done, eyelet 8 is putin place, and insulating washer I is screwed into member 4, taking care to allow the center conductor to pass through contact member I. ,By screwing the insulating washer i into place, an end of eyelet 8 will be caused to abut outer conductor ll.

As further precaution against gas leak, the cable may be introduced into a metal tube II, if desired, and a tight connection between the end of said metal tube and the barrel may be secured by using conventional coupling means 32, as shown.

The second connector member shown in Figs. 1 and 2 consists at a metallic barrel I: having suitable recesses to accommodate insulating washers l8 and I3, through which center contact piece I extends. This contact piece has tubular recesses II and II, said recess 33 receivof shielded conductor cable. 2 is the center eleclocking nut, and 6 an insulating washer of the first connecter member. A contact member I, to which the center electrode 2 or the cable I is electrically connected bysoldering, for example,

I extends through said. insulatingwasher I. Once in parts are assembled, as shown in Fig. 1. Barrel I2 is also provided with an annular recess II, which receives the slotted tubular extension ll oi the receptacle type connecter part, whereby proper electrical contact between the outer conductor and barrel I: is secured, even without tightening locking nut 5.

Once the first connector member is coupled with the second connector member and locked by nut 5 a solid contact will be established between the contact piece I and center conductor piece, H, as well as between the outer cable connector I U and barrel I! of the second connecter washers may be provided with suitable holes to r allow aerial connection between the various chambers of the connector assemblies.

It is to be understood that my invention is not limited to the'speciflc embodiments presented herein for illustration, and is susceptible of modifications within the scope of the invention as defined in the appended claims.

I claim:

1. Coupling means for electrically connecting a co-axial cable, said coupling means comprising a first connecter member adapted to be fastened at the end of a co-axial cable, and a second connecter member adapted to be assembled with said first connecter member, said connecter members being provided with means for producing a central conductor prong electrical contact, and an annular frictional contact for the outer conductor of said co-axial cable, said annular frictional contact being provided by a slotted tubular extension of said first connecter member fitting into a registering recess formed by an inner cylindrical surface of said second connecter member and the outer cylindricalsurface of an necter'member.

2. In a coupling means be fastened on the end of a c0axia1 cable, contact means arranged in said barrel, connected with the center conductor of a co-axial cable and electrically insulated from said barrel byv an insulating washer,- and a metallic member for producing electrical contact between the-outer conductor of said co-axial cable and said barrel; a second connecter element provided with a centrally arranged insulating member, a part of which is adapted to be inserted into said first connecter e1ement,'said second connecter element being adapted to be tightly connected with said first connecter element by means of a threaded metallic locking nut; said barrel of the first connecter element being provided with a slotted tubular extension fitting into a registering annular recess formed by an inner cylindrical surface of said second connecter element and an outer cylindrical surface of said centrally arranged insulating member. said second connecter element being provided with a center conductor piece led through said centrally arranged insulating member 0! said second-connecter element, said center conductor piece havinga recess registering with and receiving said contact means of said first connecter element.
