Axial advancement of the back nut subassembly toward the body subassembly causes the ferrule to deform radially inwardly and be in electrical communication with the body subassembly.

## Background
This application is a continuation-in-part application of application Ser. No. 12/502,633, filed on Jul. 14, 2009, still pending, the contents of which are incorporated by reference in their entirety.


BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to coaxial cable connectors, and particularly to connectors for use with hardline coaxial cables.
1. Technical Background
A hardline coaxial cable typically has a solid center conductor surrounded by a plastic or other dielectric material and encased within an electrically conductive solid outer conductor that may be surrounded by an outer insulative jacket. In application, each end of the cable can be terminated by a connector, which serves to electrically and mechanically engage the cable conductors to communicate signals transmitted therethrough and for gripping the outer conductor to physically secure the cable and prevent detachment during normal operation.
Historically, connectors for hardline coaxial cables have been designed to grip the cable in such a manner as to be removed from the cable at a later time if so desired. Such a feature is generally known as “re-usability.” Connectors with this capability are typically constructed of a relatively large number of components (e.g., 12 or 13 components excluding o-rings), are comparatively expensive, and many times fail to release from the cable outer conductor when so desired.
Continued advances in the state of the art have led to a general trend of cost reduced designs along with challenges to certain requirements such as re-usability. Specifically, it has been determined that it may be preferable for a connector to be “re-enterable” as opposed to reusable. In order to be re-enterable, the connector must be capable of being installed on a cable and be further capable of termination with a device or piece of equipment and, at a later time, allow access to the equipment by uncoupling the connector. The connector does not have to be removable from the cable in order to be re-enterable.
SUMMARY OF THE INVENTION

Reference will now be made in detail to the present preferred embodiment(s) of the invention, examples of which are illustrated in the accompanying drawings. Whenever possible, the same reference numerals will be used throughout the drawings to refer to the same or like parts.
Referring to FIGS. 1 and 3, one embodiment of a connector 100 according to the present invention includes a body subassembly 200 and back nut subassembly 300. Body subassembly 200 includes body 215 made from electrically conductive material, preferably metal such as aluminum, and has a first end 225 adapted to connect to an equipment port 500 (see FIG. 3) and a second end 235 having external threads 240. Body 215 is preferably a generally cylindrical, unitary piece and has a outwardly radially extending area 255 with an outer configuration (such as a hex configuration) that allows the body subassembly 200 to be attached to and tightened on an equipment port using a standard tool, such as a wrench. Body subassembly 200 includes pin 205 made from electrically conductive material, preferably a metal such as tin-plated brass, extending through the first end 225 and accessible from the second end 235. Pin 205 has a front end 260 for connecting to the equipment port 500 and a back end 265, the back end 265 having a socket contact 245 for receiving the center conductor of a coaxial cable. Socket contact 245 preferably includes a plurality of cantilevered tines 250. The second end 235 of the body subassembly 200 has a tapered portion 216. Body subassembly 200 also has an insulator 210 made from electrically non-conductive material, preferably a plastic material such as polycarbonate, disposed adjacent the first end 225 to electrically insulate and center the pin 205. An actuator 220 made from an electrically non-conductive material, preferably plastic such as cycloolefincopolymer also known as Topas® is disposed in the body subassembly 200 adjacent the second end 235. Body subassembly 200 may optionally include o-rings 270 and/or 275 to assist in sealing the junctions of the equipment port/body assembly and the body assembly/back nut assembly.
Back nut subassembly 300 includes back nut 325 made from electrically conductive material, preferably a metal such as aluminum, and has a first end 330 having internal threads 340 adapted to mate with external threads 240 and a second end 335 adapted to receive a prepared end of a coaxial cable (see FIG. 3). The inner surface of back nut 325 includes a tapered portion 350 that decreases in diameter from a first diameter D1 between the tapered portion 350 and the first end 330 of the back nut subassembly 300 to a second diameter D2 between the tapered portion 350 and the second end 335 of the back nut subassembly 300. Back nut 325 is preferably a generally cylindrical, unitary piece and preferably has an outwardly radially extending area 345 with an outer configuration (such as a hex configuration) that allows the back nut subassembly 300 to be attached to and tightened on the body subassembly 200 using a standard tool, such as a wrench. Back nut subassembly 300 houses deformable ferrule 310 made from electrically conductive and malleable material, preferably a metal such as aluminum or tin-plated brass. Ferrule 310 has a front end 317 and a back end 318. At the front end 317 of ferrule 310 is a tapered portion 311 and at the ferrule back end 318 is tapered portion 319. See also FIG. 6B. As illustrated in FIGS. 6A-6C, the ferrule 310 has at least one and preferably at least two blind slots 312 at the front end 317. The blind slots 312 have edges 313, which assist in the functioning of the connector 100 as discussed below. Ferrule 310 preferably has an outer diameter that is smaller than first diameter D1 and greater than second diameter D2 of the inner surface of back nut 325. The inner surface of ferrule 310 may optionally have grooves and ridges 316 to enhance gripping of an outer conductor of a coaxial cable. Back nut subassembly 300 also includes a sleeve 315, preferably made from electrically conductive material, which may include a metal such as aluminum. Alternatively, sleeve 315 can be made from a plastic material. Sleeve 315 is a generally cylindrical unitary piece and preferably has an increased diameter front portion 355 and a decreased diameter back portion 360 wherein the outer diameter of back portion 360 is less than second diameter D2 such that an annular gap 365 is present between the outer diameter of back portion 360 and inner surface of back nut 325 at the second diameter D2. The outer diameter of back portion 360 is also smaller than inner diameter of ferrule 310 such that the annular gap 365 also extends between decreased diameter of back portion 360 and the inner surface of ferrule 310. Back nut subassembly 300 includes retaining ring 320 that is disposed around the ferrule 310 as discussed in more detail below.
Turning to FIG. 2, a prepared end of a hardline coaxial cable 1000 to be used with the connector 100 is shown. Hardline coaxial cable 1000 includes a center conductor 1005 made from electrically conductive material, preferably a metal such as copper clad aluminum, an outer conductor 1010 made from electrically conductive material, preferably a metal such as aluminum, an insulative layer 1015 made from electrically non-conductive material, preferably foamed polyethylene plastic, and, optionally, an outer protective jacket 1020 preferably made from PVC.
FIG. 3 illustrates the connector 100 where the back nut subassembly 300 is detached from the body subassembly 200 and the first end 225 of the body subassembly 200 has been attached to the equipment port 500 and a prepared end of a coaxial cable 1000 has been inserted into the second end 335 of the back nut subassembly 300. As noted above, the connector 100 is shipped in the configuration shown in FIG. 1, and an installer detaches the back nut subassembly 300 from the body subassembly 200. Next, the installer attaches the first end 225 of the body subassembly 200 to an equipment port 500 and inserts the prepared end of the hardline coaxial cable 1000 into the second end 335 of the back nut subassembly 300. Preferably, back nut subassembly 300 houses sleeve 315 such that the outer conductor 1010 of hardline coaxial cable 1000 is inserted into annular gap 365 between the back portion 360 of the sleeve 315 and the inner surface at second diameter D2 and between the back portion 360 of the sleeve 315 and the inner surface of the ferrule 310. At this point, the back nut subassembly 300, with the prepared end of the hardline coaxial cable 1000 inserted therein, is ready to be reattached to the body subassembly 200.
FIG. 4 illustrates the connector 100 where back nut subassembly 300 has been fully installed and tightened on body subassembly 200. The back nut subassembly 300, including back nut 325, is rotatable with respect to both the body subassembly 200 already attached to the equipment port 500 and the hardline coaxial cable 1000 inserted therein. As the back nut subassembly 300 is advanced axially toward the body subassembly 200 as a result of the mating of the external threads 240 of the body subassembly 200 with the internal thread 340 of the back nut subassembly 300 and rotating the back nut subassembly 300 relative to the body subassembly 200 and the hardline coaxial cable 1000, the tapered portion 311 at the front end 317 of the ferrule 310 engages the tapered portion 216 at the second end 235 of the body 215. Edges 313 of the blind slots 312 on the ferrule 310 engage tapered surface 216 of the body 215 normal to, or at least nearly normal to, the tapered surface 216 of the body 215, causing the ferrule 310 to resist rotation relative to the body 215.
As the back nut subassembly 300 is continually advanced axially toward the body subassembly 200 as a result of the mating of the external threads 240 of the body subassembly 200 with the internal thread 340 of the back nut subassembly 300 and rotating the back nut subassembly 300 relative to the body subassembly 200 and the hardline coaxial cable 1000, the tapered portion 350 contacts the ferrule 310 at the tapered portion 319 at the back end 318 and causes at least a portion of the ferrule 310 to deform radially inwardly as shown in FIG. 4. As the ferrule 310 deforms radially inwardly against outer conductor 1010 of the hardline coaxial cable 1000, a gripping and sealing relationship is established between the ferrule 310 and the outer conductor 1010 of the hardline coaxial cable 1000 providing electrical and mechanical communication between ferrule 310 and outer conductor 1010. Back nut subassembly 300 preferably houses sleeve 315 such that as the ferrule 310 deforms radially inwardly against the outer conductor 1010, at least a portion of the outer conductor 1010 that is inserted between the decreased diameter of back portion 360 of the sleeve 315 and the inner surface of ferrule 310 is clamped between the sleeve 315 and the ferrule 310 as shown in FIG. 4. Meanwhile, the center conductor 1005 is received in socket contact 245 and axial advancement of the ferrule 310 (and possibly sleeve 315) toward actuator 220 causes actuator 220 to drive cantilevered tines 250 radially inward against center conductor 1005 with the chamfered portion of the actuator 220. In the installed position in FIG. 4, electrical communication between the outer conductor 1010 and the body 215 of the body subassembly 200 is established through the ferrule 310.
FIG. 5 shows the connector 100 in the re-enterable state wherein back nut subassembly 300 has been detached from body subassembly 200, and body subassembly 200 remains installed in equipment port 500. Back nut subassembly 300 is detached from body subassembly 200 by rotating the back nut 325 relative to the hardline coaxial cable 1000 and the body subassembly 200 such that the back nut subassembly 300 is advanced axially away from the body subassembly 200 as a result of the mating of the external threads 240 of the body subassembly 200 with the internal threads 340 of the back nut subassembly 300. During and after detachment of back nut subassembly 300 from body subassembly 200, the inward radial deformation of ferrule 310 against the outer conductor 1010 that occurred during the first installation is maintained as shown in FIG. 5. Likewise, electrical and mechanical communication between ferrule 310 and outer conductor 1010 is maintained upon detachment of back nut subassembly 300 from body subassembly 200. In addition, back nut subassembly 300 houses sleeve 315 such that the clamping of at least a portion of outer conductor 1010 between sleeve 315 and ferrule 310 (or at least a portion of the clamped region between sleeve 315 and ferrule 310) is maintained upon detachment of the back nut subassembly 300 from the body subassembly 200. Upon detachment, back nut 325 remains rotatably captivated about cable 1000 and will re-seat against ferrule 310 upon re-installation to body assembly 200.
Ferrule 310 is preferably permanently deformed around the outer conductor 1010, and back nut subassembly 300 can be repeatedly attached to and detached from body subassembly 200 while still maintaining electrical and mechanical communication and environmental sealing between ferrule 310 and outer conductor 1010. In addition, back nut subassembly 300 can be repeatedly attached to and detached from body subassembly 200 while still maintaining the clamp of at least a portion of outer conductor 1010 between sleeve 315 and ferrule 310. As a result, electrical and mechanical communication is maintained between outer conductor 1010 and both ferrule 310 and sleeve 315, allowing ferrule 310 to function as a coaxial outer conductor. An outer conductor path can then be continued from the ferrule 310 to the body 215 (see, e.g., FIG. 4 showing electrical and mechanical communication between ferrule front end 317 and body 215) and therethrough to the equipment port 500.
Turning to FIG. 7A, the retaining ring 320 is illustrated in a state of partial assembly on the ferrule 310. Retaining ring 320 is axially advanced over the tapered portion 311 at the front end 317 of the ferrule 310 in the direction of the second end 318 of the ferrule 310. The retaining ring 320 has a generally c-shaped configuration and a slot 321 in the retaining ring 320 permits the retaining ring 320 to expand and pass over the ferrule 310 as illustrated in FIG. 7B. It is noted that the sleeve 315 is also illustrated as being disposed within the ferrule 310.
In FIG. 7C, retaining ring 320 is axially advanced into a groove 314 extending radially inwardly in the outer surface of the ferrule 310. Retaining ring 320, due to its resilient nature, snaps into the groove 314 and is forced to remain relatively radially evenly disposed about the groove 314 by contact between the tapered portion 322 of the groove 314 in the ferrule 310 and the internal surface 323 of the retaining ring 320. This centering action causes retaining ring 320 to be co-cylindrically aligned with the ferrule 310.
In FIG. 7D, the back nut 325 is axially advanced from the second end 318 of the ferrule 310 in the direction of the front end 317 of the ferrule 310. As a result of the axial advancement of the back nut 325, the retaining ring 320, which is disposed about the ferrule 310, is also disposed at least partially within the through bore 370 of the back nut 325. Coincidentally, as the back nut 325 is axially advanced towards the front end 317 of the ferrule 310, the chamfer 326 of the back nut 325 begins to funnel the retaining ring 320 into the recess 327 of the back nut 325.
In FIG. 7E, upon further advancement of the back nut 325 over the ferrule 310 and over the retaining ring 320, contact between the through bore 370 and tapered diameter 368 of the retaining ring 320 causes the retaining ring 320 to compress radially inwardly. Specifically, the through bore 370 forces the cross sectional beam 375 of the retaining ring 320 to radially compress in diameter and also torsionally conform to both the groove 314 and the tapered portion 322 of the ferrule 310, allowing the back nut 325 to continue to advance without the need for alignment and/or pre-compression tooling to be applied to the retaining ring 320 in what is known as a blind assembly operation.
In FIG. 7F, the back nut 325 is completely advanced until the retaining ring 320 passes completely beyond the through bore 370 and into recess 327 of the back nut 325, at which point the retaining ring 320 is permitted to re-expand radially outwardly to its original configuration, now diametrally bounded within the recess 327 and axially bounded by the rearward facing annular shoulder 382. Back nut 325 now rotatably engages the ferrule 310 while permitting only limited axial movement of the ferrule 310 within the recess 327. Simultaneously, ferrule 310 remains co-cylindrically aligned with the back nut 325 as a result of the retaining ring 320.
FIG. 8 is a cross section view along the centerline of an optional embodiment where greater pressure is exerted on the clamping mechanism, purposely forming in the outer conductor 1010 and the sleeve 315 a localized annular depression. In this configuration, the ferrule 310 is circumferentially compressed by the tapered portion 350 with enough pressure to cause localized annular depressions of both the outer conductor 1010 and the sleeve 315. As a result, resistance to Radio Frequency Interference leakage ca
Can be increased by the relatively convoluted path created by the radial deformation and outer conductor retention characteristics can be improved. The variance in impedance match caused by the localized annular depression can be electrically compensated by incorporating internal step features or bores (not shown) in sleeve front end 355, and can thereby render excellent electrical performance characteristics such as improved Return Loss and reduced Radio Frequency Interference (radiation of signal).
It will be apparent to those skilled in the art that various modifications and variations can be made to the present invention without departing from the spirit and scope of the invention. Thus, it is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
