`ABSTRACT
`
`The coaxial connector has a coupling nut, a post, a hollow
`body, and a ring that prevents interfaces from gapping and
`provide a robust alternative ground path that also RF shields
`the connector from both ingress and egress. The ring is biased
`radially outward to engage the coupling nut, thereby biasing
`the coupling nut in a rearward direction and, at the same time,
`biasing the post in a forward direction to engage a terminal.

`INTEGRALLY CONDUCTIVE LOCKING
`COAXIAL CONNECTOR
`
`CROSS-REFERENCE TO RELATED
`APPLICATIONS
`
`This application claims the benefit of, and priority to U.S.
`Provisional Patent Application No. 61/258,871 filed on Nov.
`6, 2009 entitled, “Integrally Conductive Locking Coaxial
`Connector”, the content of which is relied upon and incorpo-
`rated herein by reference in its entirety.
`
`BACKGROUND OF THE INVENTION
`
`1. Field of the Invention
`
`The present invention relates generally to coaxial cable
`connectors, and particularly to coaxial cable connectors
`capable of securely connecting a coaxial cable to a terminal.
`2. Technical Background
`With the advent of digital signal in CATV systems, a rise in
`customer complaints due to poor picture quality in the form of
`signal interference resulting in what is known as “tiling” and
`the like has also occurred. Complaints of this nature result in
`CATV system operators having to send a technician to
`address the issue. Frequently it is reported by the technician
`that the cause of the problem is a loose F connector fitting.
`Type F connector fittings may be loose for many reasons;
`sometimes they are not properly tightened due to installation
`rules of system operators that prohibit the use of wrenches
`in-doors on customer equipment. Other times a homeowner
`may relocate equipment after the technician departs and may
`not adequately secure the F connectors. Additionally, some
`claim that F connector coupler loosen due to vibration and/or
`heat and cold cycles.
`Regardless, an improperly installed connector may result
`in poor signal transfer because there are discontinuities along
`the electrical path between the devices, resulting in a leak of
`radio frequency (“RF”) signal. That leak may be in the form
`of signal egress where the RF energy radiates out of the
`connector/cable arrangement. Altemately, an RF leak may be
`in the form of signal ingress where RF energy from an exter-
`nal source or sources may enter the connector/cable arrange-
`ment causing a signal to noise ratio problem resulting in an
`unacceptable picture.
`Many of the current state of the art F connectors rely on
`intimate contact between the F male connector interface and
`the F female connector interface. If for some reason, the
`connector interfaces are allowed to pull apart from each other,
`such as in the case of a loose F male coupler, an interface
`“gap” may result. This gap can be a point of an RF leak as
`previously described.
`To overcome this issue a number of approaches have been
`introduced including U.S. Pat. No. 7,114,990 (Bence, et al.);
`U.S. Pat. No. 7,479,035 (Bence, et al.); U.S. Pat. No. 6,716,
`062 (Palinkas, et al.) and US Patent application 20080102696
`(Montena). While these approaches have been successful in
`varying degrees it is desirable to provide a functioning con-
`nector junction that will operate at various stages of engage-
`ment.
`
`To address the issue of loosening Type F couplers a number
`of approaches have been introduced including a lock-washer
`design produced by Phoenix Communications Technologies
`International (PCT) known as the TRS connector. While this
`approach may be somewhat successful in varying degrees, it
`is desirable to provide a functioning connector junction that
`will provide an improved locking mechanism.

`It would be desirable therefore to provide a coaxial con-
`nector that provides a connection without gapping, an alter-
`native ground path, and a way to RF shield both ingress and
`egress.
`
`SUMMARY OF THE INVENTION
`
`Disclosed herein is coaxial cable connector for coupling an
`end of a coaxial cable to a terminal, the coaxial cable connec-
`tor that includes a body, the body comprising a rear end, a
`front end, and an internal surface extending between the rear
`and front ends of the body, the internal surface defining a
`longitudinal opening, a post disposed at least partially within
`the longitudinal opening of the body, the post comprising a
`front end and an outer surface, the outer surface having a
`groove disposed adjacent the front end, a coupling nut dis-
`posed proximate the front end of the body to engage a termi-
`nal, the coupling nut having a front end and a back end and an
`opening extending therebetween,
`the opening having an
`internal surface, the internal surface having a threaded por-
`tion to engage the terminal, a forward facing surface to
`engage the tubular post and a forward facing inclined surface,
`and a ring having an internal surface, a forward facing sur-
`face, and a rearward facing inclined surface, the ring disposed
`in the groove between the coupling nut and the tubular post,
`the ring biased radially outward with at least a portion of the
`rearward facing inclined surface of the ring engaging at least
`a portion of the forward facing inclined surface of the cou-
`pling nut.

`
`DETAILED DESCRIPTION OF THE PREFERRED
`EMBODIMENTS
`
`Reference will now be made in detail to the present pre-
`ferred embodiment(s) ofthe invention, examples ofwhich are
`illustrated in the accompanying drawings. Whenever pos-
`sible, the same reference numerals will be used throughout
`the drawings to refer to the same or like parts.
`Referring to FIG. 1, a coaxial connector 20 has a coupling
`nut 30, a post 60, a ring 90, a sealing member 100, a body 110,
`a gripping member 150, and compression ring 160. The
`coaxial connector 20 is an axial-compression type coaxial
`connector and the connection ofthe coaxial connector 20 to a
`coaxial cable is known in the art. The coaxial connector 20 is
`
`illustrated in FIG. 1 in its unattached, uncompressed state. As
`described in more detail below, the ring 90 is snap fit onto the
`post 60. The coupling nut 30 is then disposed over the post 60
`and the ring 90. The body 110 is then press-fit over the post 60
`(and into the coupling nut 30). Finally, the gripping number
`150, with the compression ring 160 disposed therein, is press-
`fit on to the body 110 to complete the coaxial connector 20.
`The coupling nut 30 is free to spin around the post 60 in the
`front portion of the body 110. Also, as described in more
`detail below, the coupling nut 30 also has limited axial move-
`ment so as to be allowed to engage a terminal.
`As illustrated in more detail in FIG. 2, the coupling nut 30
`has a front end 32, a back end 34, and an opening 36 extending
`there between. The opening 36 of the coupling nut 30 has an
`internal surface 38. The internal surface 38 includes a
`
`threaded portion 40, a forward facing surface 42 to engage the
`post 60 and a forward facing inclined surface 44. The cou-
`pling nut 30 also has a smooth outer surface 46 adjacent the
`front end 32 and a hexagonal configuration 48 adjacent the
`back end 34. The coupling nut 30 is preferably made from a
`metallic material, such as brass, and it is plated with a con-
`ductive, corrosion-resistant material, such as nickel.
`The post 60, illustrated in FIG. 3, includes a front end 62,
`rear end 64, and an opening 66 extending there between. The
`post 60 also includes an outer surface 68, the outer surface 68
`having a groove 70 near the front end 62. The groove 70 also
`includes a bottom surface 72 and a rearward facing surface
`74. The post 60 is also made from a metallic material, such as
`brass, and it is also plated with a conductive, corrosion-resis-
`tant material, such as tin.
`FIG. 4 illustrates the ring 90, having a shape that can
`generally be described as frustoconical. The ring 90 has an
`internal surface 92, a forward facing surface 94, and a rear-
`ward facing inclined surface 96. The ring 90 also has an
`opening 98 along one side to allow a change in the diameter of
`the ring 90. The ring 90 is preferably made from a metallic
`material, such as heat-treated beryllium copper and is an
`elastic element. That is, the ring 90 can be compressed and
`expand, as described below.
`Turning now to FIG. 5, the coaxial connector 20 has been
`installed onto a coaxial cable 180 as is known in the art. The
`
`coupling nut 30 ofthe coaxial connector 20 has been turned to
`engage a terminal 190 and, in particular, the threads 192 ofthe
`terminal 190. It should be noted that in this configuration, as
`well as the ready-to-be-shipped configuration of FIG. 1, the
`coupling nut 30 is biased rearwardly to engage the body 110.

`
`The ring 90, disposed in the groove 70, is biased radially
`outward from the groove 70 so as to engage the coupling nut
`30. Preferably, the outer diameter of the ring 90 is larger than
`the internal diameter of the coupling nut 30, causing the ring
`90 to engage the internal surface 38 of the coupling nut 30.
`The rearwardly facing inclined surface 96 therefore engages
`the forward facing inclined surface 44 of the coupling nut 30.
`Since the forward facing surface 94 ofthe ring 90 engages the
`rearward facing surface 74 of the groove 70, the coupling nut
`30 is biased rearwardly toward the body 110 and relative to
`the post 60.
`It should also be noted in FIG. 5 that the post 60 engages the
`terminal 190 with just a few turns of the coupling nut 30.
`Additionally, the coupling nut 30 has not yet begun to move
`axially toward the terminal 190 relative to the post 60 and the
`body 110.
`FIG. 6 illustrates coupling nut 30 fully engaging the termi-
`nal 190. With the post 60 having engaged the terminal 190 at
`the beginning of engagement and as the coupling nut 30 was
`rotated onto terminal 190, the coupling nut 30 moved axially
`forward relative to the post 60 and the ring 90. As can be seen
`in FIG. 6, the forward facing surface 44 ofthe coupling nut 30
`has moved along the rearwardly facing inclined surface 96,
`radially compressing the ring 90. Since the forward facing
`inclined surface 44 of the coupling nut 30 constantly engages
`the rearwardly facing inclined surface 96 of the ring 90, an
`alternative ground path is created through the coupling nut 30
`and the ring 90. The coupling nut 30 can be rotated until the
`forward facing surface 42 of the coupling nut 30 engages the
`rearward facing surface 74 ofthe post 60. The forward facing
`inclined surface 44 of the coupling nut 30 engaging the rear-
`wardly facing inclined surface 96 of the ring 90 and the ring
`90 engaging the bottom surface 72 of the groove 70 impart
`both axial and radial forces that both bias, or load, and restrain
`the coupler nut 30 from rotating.
`It should also be noted that the radially outward biasing
`effect of the ring 90 also tends to center the coupling nut 30
`relative to the post 60 (and therefore the center conductor of
`the coaxial cable 180). The outward biasing ofthe ring 90 also
`causes thread loading on the coupling nut 30. Since the cou-
`pling nut 30 is biased in a rearward direction (axially), it
`imparts a force on the threads 192 of the terminal 190. This
`force assists in maintaining a positive axial engagement
`between the terminal 190 and the coaxial connector 20. More-
`
`over, when the coaxial connector 20 (and the coupling nut 30
`in particular) is unthreaded, the coupling nut 30 will tend to
`pop offofthe terminal 190, returning the coaxial connector 20
`to the state illustrated in FIG. 1.
`
`The sealing member 100, illustrated in FIG. 6 as being at
`the junction of the body 110 and the post 60, prevents mois-
`ture and debris from entering into the coaxial connector 20. It
`should be noted that the coupling nut 30 moves axially for-
`ward over the sealing member 100. As illustrated in FIG. 6,
`the sealing member 100 is an O-ring.
`FIG. 7 illustrates an alternative embodiment of a coaxial
`
`connector 20'. The coaxial connector 20' has a larger sealing
`member 100'. Coaxial connector 20' has a coupling nut 30', a
`post 60', a ring 90', a sealing member 100', a body 110', a
`gripping member 150', and compression ring 160'. Generally,
`the difference in co-axial connector 20' is that the configura-
`tion of the internal surface 38' of coupling nut 30' and the
`outer surface of body 110' are slightly different to accommo-
`date a larger sealing member 100'. Rather than sealing the
`junction of three components (i.e., the coupling nut, the post,
`and the body), only the junction oftwo components are sealed
`
`

`in coaxial connector 20'. The rest of the structure, as well as
`the workings of, the coaxial connector 20' are the same as the
`prior embodiment.
`An alternative embodiment of the coaxial connector 20" is
`
`illustrated in FIG. 8 according to the present invention. The 5
`coaxial connector 20" includes a coupling nut 30", a post 60",
`a ring 90", a sealing member 100", and a body 110". The
`coaxial connector 20" is configured as a pin-type connector
`arrangement wherein the central conductor 200" and the post
`60" remain in contact with the terminal (not shown). The
`operation of the coupling nut 30", the ring 90", and the post
`60" operate in the same fashion as described above with
`respect to coaxial connector 20.
`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.
