3,963, tiled January 21, 1960, entitled Coaxial Con-v. t
nector, now abandoned. n
It is an object of this invention to provide a coaxial cable connector adapted to connect the center conductors and outer conductors of the free ends of two cable segments which have the outer conductors and insulation stripped away from the center conductors, which includes: end caps being internally threaded at one end and having an inwardly extending flange at the other'endv with an end cap being placed lover the outer conductor 0f each of the free ends lianged end first; a retainer ring adapted to engage the inwardly extending ilange of the end caps, being soldered to the outer conductor of each cable end; an externally threaded sleeve containing a Teflon positioning sleeve and a sleeve having spring members at each end for engaging the center conductorssaid threaded sleeve being in threaded engagement with each of the end caps which are tightened on the sleeve so that the inwardlyextending lianges of the end caps urge the retaining rings toward one another and against the ends of the threaded sleeve, positioning sleeve to firmly hold the connection.
This land other objects and inventions will become more apparent when a preferred embodiment ofy this invention is considered in connection with the drawings in which:
FIGURE 1 is a cross section of an embodiment of this invention connecting two coaxial cables;
FIGURE 2 is an end view of the connector; and
FIGURE 3 is a sectioned view of the spring sleeve which connects the two center conductors.
In FIGURE 1 is shown the free ends of two coaxial cables 20, 20A, having, respectively, center conductors 22, 22A, insulation 24, 24A, and outer conductors 26, 26A. The insulation 24, 24A and outer conductors 26, 26A are stripped away in this embodiment for .100" for an outer conductor diameter of .140. Soldered at 29, 29A to outer conductors 26, 26A, respectively, are rings 28, 28A, which have shoulders 27, 27A, respectively, formed intermediately thereof. Rings 28, 28A are urged together by the inwardly extending flanges 30, 30A, lof end caps 32, 32A which are threadedly engaged with an externally threaded sleeve 34, the ends of which are tightened against shoulders 27, 27A.
Located inside sleeye 34 is a Telion positioning sleeve 36 in which is a spring sleeve 38 having a plurality ot lingers 40 at one end and lingers 40A at Athe other, as shown in FIGURE 3. In the relaxed position the lingers 40, 40A of spring sleeve 38 come together at their outer ends and, therefore, when the center conductors 22, 22A are inserted in the ends ot'` the sleeve 38, the linger-S40, 40A, are separated and exert a spring pressure on the 3,47,051 Patented Sept. l, 1.964

Although this invention has been disclosed and illus-.-v
trated with reference to particular applications, the principles involved are susceptible of numerous other applications which will be apparent to persons skilled in the art. The invention is, therefore, to be limited only as indicated by the scope of the appended claims.
Having thus described my invention, Iclaim: l. A connector for connecting the free ends of two coaxial cables having their outer conductor and insulation stripped away to expose a predetermined length of the inner conductor comprising two internally threaded end caps, one end cap rotatably mounted on one cable, the other end cap rotatably mounted on the other cable, a rst ring being bonded to the outer conductor of said one cable, a second ring being bonded to the outer conductor of said other cable, an externallythreaded sleeve which is threadedly engageable with both of said threaded end caps, rigid tubular insulating means closely fitting within said sleeve intermediate the ends thereof, a double-ended socket contact wholly within and supported by said sleeve for receiving and electrically contacting the exposed lengths of the inner conductors of saidv end cap for rotatably engaging said second ring, the
adjacent ends of said rings and cables slidably extending into the 'ends l of said sleeve and being urged toward each other by said engaging means as said end caps are screwed on said sleeve until said inner conductors make electrical contact with said socket contact and said cainner conductor, a metallic ring surrounding and se-4 cured to the outer conductor of said cable, said ring terminating llush with the end of said outer conductorv of Vthe cable and having a portion slidably telescopicallyreceived in one end of said casing member, and a nut cooperably associated with said casing member and ring for holding the ring and cable in telescopic relation with said casing member with the ends of said insulating means and said cable insulation in abutting relation.
3. The combination defined in claim 2, lwherein said ring has an external shoulder cooperable with the end of said casing member to limit movement of said ring'and cable into the casing member after said inner conductor engages said socket Contact.r
4. The combination defined in claim 2 further comprising means for limiting axial movement of said insulating means into said casing member toward the other end of the latter.
5. The combination defined in claim 4, wherein said last-named means comprises a second coaxial cable, ring and nut in combination with each other and with the other end of said casing member in the same manner as said first-named cable, ring and nut are combined with each other and with said one end of the casing member.
6. The combination defined in claim 1, wherein said insulating means is a rigid unitary tube slidably received in said casing member and held therein by said nut in end-to-end abutment with said cable and ring.
7. The combination defined in claim 1, wherein the outer diameter of said socket contact is greater than the diameter of said inner conductor of the cable and the inner diameter of said casing member surrounding said insulating means is greater than the inner diameter of said outer conductor of the cable;
