AT TORN EY United States Patent 3,142,721 CONNECTOR FOR J DINING THE OUTER CONDUC- TOR OF A COAXIAL CABLE TO A WALL James G. Long, Fairlield, Coma, assignor to Burndy Corporation, a corporation of New York Filed Dec. 19, 1960, Ser. No. 76,570 2 Claims. (Cl. 174-65) This invention relates to coaxial cable connectors, and more particularly, to a connector for connecting an outer coaxial conductor of a coaxial cable to a panel or bulkhead, and passing the insulated center conductor through an aperture in the panel.

Hitherto, such an arrangement required soldering or bolting a connector to the panel, and this required unusual manual dexterity and care in installation. Further, such connectors were difficult to seal against environmental hazards.

Accordingly, the objects of the instant invention are to provide a coaxial cable connector which can be easily and quickly installed to mount the cable to an apertured panel; to provide such a connector containing a minimum number of parts; and to provide a connector of the foregoing characteristics which forms a reliable and eificient joint.

A feature of this invention is a pair of coaxial flanged rings of unequal malleability which are crimped together and unequally deformed longitudinally to mount a coaxial cable to a panel.

These and other objects and features of this invention will become more apparent by reference to the following description taken in conjunction with the accompanying drawings, in which:

FIG. 1 is a longitudinally sectioned view taken through the complete coaxial connection prior to crimping; and

FIG. 2 is a longitudinally sectioned view taken through the complete coaxial connection subsequent to crimping.

The figures illustrate a coaxial connector which mechanically mounts a coaxial cable 1 to a panel 2, electrically connects the outer coaxial conductor 3 to the panel 2, passes the insulated center conductor 4 through a hole 5 in the panel, and provides a full seal about the outer conductor and the hole.

The coaxial cable comprises an outer insulation 6, an outer conductor 3, generally of woven or spiral construction, an inner insulation 7, and a center conductor 4.

The connector comprises an inner tube 8 having a flange 9, and made of a relatively hard metal; a coaxial dielectric gasket 10 made of resilient material such as rubber; and an outer tube 11 having a flange 12, and made of a relatively malleable metal.

The connector is assembled by cutting back the outer insulation 6 as shown, to expose a length of the outer conductor 3. The malleable outer tube 11 is then slipped over the inner insulation until it covers the exposed length of outer conductor 4 and part of the outer insulation 6, as shown. The resilient gasket 10 is then slipped into place against the flange 12 of the outer tube 11. Next the inner insulation 7 and center conductor 4 are passed through the hole 5 in the panel 2. Thereafter, the hard inner tube 8 is slipped over the inner insulation 7 through the hole 5, the gasket 10, and between the inner insulation 7 and the outer conductor 3. The two flanges sandwich 3,142,721 Patented July 28, 1964 the gasket and the panel between themselves, and are frictionally held in place by the close interfitting of the several coaxial elements.

By means of a suitable crimping tool, not shown, a plurality of annular crimps 13a are made around the periphery of the malleable outer tube 11. These crimps 13a compress the tube 11 about the outer conductor 3 and mechanically and electrically crimp it at 131; to the hard and relatively undeformed inner tube. The crimps 13a also extrude the malleable outer tube 11 longitudinally and force its flange 12 against the gasket 10. A tight mechanical joint between the two flanges 9 and 12 and the gasket 10 and panel 2 is thereby provided. The flange 9 is also electrically joined to the panel 2. A second plurality of annular crimps 14 may be provided in the end of the outer tube 11 which provide an insulation shroud to seal the end of the outer insulation 6.

If a less positive seal between the outer flange 9 and the panel 2 is acceptable, the resilient gasket may be omitted.

The invention has thus been described, but it is desired to be understood that it is not confined to the particular forms or usages 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 the invention, and, therefore, the right is broadly claimed to employ all equivalent instrumentalities coming within the scope of the appendant claims, and by means of which objects of this invention are attained, and new results accomplished, as it is obvious that the particular embodiments'herein shown and described are only some of the many that can be employed to obtain these objects and accomplish these results.

I claim:

1. A connection electrically joining the outer conductor of a coaxial cable to an apertured panel and passing the inner conductor through the aperture comprising: an outer tube having a flange thereon and made of a relatively malleable metal; said outer tube disposed over and coaxial with the outer conductor of said coaxial cable, with its flange on one side of the panel; an inner tube having a flange thereon and made of a relatively nonmalleable metal; said inner tube disposed through the panel aperture and under, in contact with and coaxial with the outer conductor, with its flange on the other side of the panel; said outer tube deformed radially to join the outer conductor to the inner tube, and deformed longitudinally to grip the panel between the said inner tube flange and the outer tube flange.

2. A connection according to claim 1 further including a resilient gasket, said gasket disposed between said outer tube flange and the one side of the panel.
