The following relates to connectors used in coaxial cable communication applications, and more specifically to coaxial connectors having features for improving the efficiency of structures and processes for attaching the connectors to coaxial cables.
Broadband communications have become an increasingly prevalent form of electromagnetic information exchange and coaxial cables are common conduits for transmission of broadband communications. Coaxial cables are typically designed so that an electromagnetic field carrying communications signals exists only in the space between inner and outer coaxial conductors of the cables. This allows coaxial cable runs to be installed next to metal objects without the power losses that occur in other transmission lines, and provides protection of the communications signals from external electromagnetic interference. Connectors for coaxial cables are typically connected onto complementary interface ports to electrically integrate coaxial cables to various electronic devices and cable communication equipment. Connection is often made through rotatable operation of an internally coupling member of the connector about a corresponding externally threaded interface port. Fully tightening the threaded connection of the coaxial cable connector to the interface port helps to ensure a ground connection between the connector and the corresponding interface port. However, often connectors are not properly tightened or otherwise installed to the interface port and proper electrical mating of the connector with the interface port does not occur. Moreover, when attached to an interface port, common connectors are often still susceptible to the unwanted introduction of environmental contaminants into the connector. In addition, common connectors often utilize cumbersome and/or costly components and installation processes associated with attaching the connectors to coaxial cables.
Hence a need exists for an improved connector having structural features that help prevent the entry of unwanted environmental contaminants into the coaxial cable connector, and that improve cost and effectiveness with relation to how the connector attaches to a coaxial cable.

Embodiments of connector 100 may include a coupling member 30a. The coupling member 30a of embodiments of a coaxial cable connector 100 has a first forward end 31a and opposing second rearward end 32a. The coupling member 30a may comprise internal threading 33a extending axially from the edge of first forward end 31a a distance sufficient to provide operably effective threadable contact with the external threads 23 of a standard coaxial cable interface port 20 (as shown, by way of example, in
Moreover, embodiments of coupling member 30a may include an outer surface feature(s) 38a proximate or otherwise near the second end 32a to improve mechanical interference or friction between the coupling member 30a and the sleeve 90. For instance, the outer surface feature 38a may extend completely or partially around the outer surface 36a proximate the second 32a of the coupling member 30a to increase a retention force between an inner surface 93 of the sleeve 90 and the outer surface 36a of the coupling member 30a. The outer surface feature 38a may include a knurled surface, a slotted surface, a plurality of bumps, ridges, grooves, or any surface feature that may facilitate contact between the sleeve 90 and the coupling member 30a. In one embodiment, the coupling member 30a may be referred to as a press-fit coupling member.
The structural configuration of the coupling member 30a may vary according differing connector design parameters to accommodate different functionality of a coaxial cable connector 100. For instance, the first forward end 31a of the coupling member 30a may include internal and/or external structures such as ridges, grooves, curves, detents, slots, openings, chamfers, or other structural features, etc., which may facilitate the operable joining of an environmental sealing member, such a water-tight seal or other attachable component element, that may help prevent ingress of environmental contaminants, such as moisture, oils, and dirt, at the first forward end 31a of the coupling member 30a, when mated with an interface port 20. Those in the art should appreciate that the coupling member 30a need not be threaded. Moreover, the coupling member 30a may comprise a coupler commonly used in connecting RCA-type, or BNC-type connectors, or other common coaxial cable connectors having standard coupler interfaces. The coupling member 30a may be formed of conductive materials, such as copper, brass, aluminum, or other metals or metal alloys, facilitating grounding through the coupling member 30a. Further embodiments of the coupling member 30a may be formed of polymeric materials and may be non-conductive. Accordingly, the coupling member 30a may be configured to extend an electromagnetic buffer by electrically contacting conductive surfaces of an interface port 20 when a connector 100 is advanced onto the port 20. In addition, the coupling member 30a may be formed of both conductive and non-conductive materials. For example the external surface of the coupling member 30a may be formed of a polymer, while the remainder of the coupling member 30a may be comprised of a metal or other conductive material. The coupling member 30a may be formed of metals or polymers or other materials that would facilitate a rigidly formed coupling member body. Manufacture of the coupling member 30a may include casting, extruding, cutting, knurling, turning, tapping, drilling, injection molding, blow molding, combinations thereof, or other fabrication methods that may provide efficient production of the component. The forward facing surface 35a of the coupling member 30a faces a flange 44 the post 40 when operably assembled in a connector 100, so as to allow the coupling member 30a to rotate with respect to the other component elements, such as the post 40 and the connector body 50, of the connector 100.
Embodiments of connector 100 may include a post 40. The post 40 comprises a first forward end 41 and an opposing second rearward end 42. Furthermore, the post 40 may comprise a flange 44, such as an externally extending annular protrusion, located at the first end 41 of the post 40. The flange 44 includes a rearward facing surface 45 that faces the forward facing surface 35a, 35b, 35c of the coupling member 30a, 30b, 30c when operably assembled in a coaxial cable connector, so as to allow the coupling member 30 to rotate with respect to the other component elements, such as the post 40 and the connector body 50, of the connector 100-128. The rearward facing surface 45 of flange 44 may be a tapered surface facing the second rearward end 42 of the post 40. Further still, an embodiment of the post 40 may include a surface feature 47 such as a lip or protrusion that may engage a portion of a connector body 50 to secure axial movement of the post 40 relative to the connector body 50. However, the post need not include such a surface feature 47, and the coaxial cable connector 100-128 may rely on press-fitting and friction-fitting forces and/or other component structures having features and geometries to help retain the post 40 in secure location both axially and rotationally relative to the connector body 50. The location proximate or near where the connector body is secured relative to the post 40 may include surface features 43, such as ridges, grooves, protrusions, or knurling, which may enhance the secure attachment and locating of the post 40 with respect to the connector body 50. Moreover, various components having larger or smaller diameters can be readily press-fit or otherwise secured into connection with each other. Additionally, the post 40 may include a mating edge 46, which may be configured to make physical and electrical contact with a corresponding mating edge 26 of an interface port 20 (as shown in exemplary fashion in
Embodiments of a coaxial cable connector, such as connector 100, may include a connector body 50. The connector body 50 may comprise a first end 51 and opposing second end 52. Moreover, the connector body may include a post mounting portion 57 proximate or otherwise near the first end 51 of the body 50, the post mounting portion 57 configured to securely locate the body 50 relative to a portion of the outer surface of post 40, so that the connector body 50 is axially secured with respect to the post 40, in a manner that prevents the two components from moving with respect to each other in a direction parallel to the axis of the connector 100. The internal surface of the post mounting portion 57 may include an engagement feature, such as an annular detent or ridge having a different diameter than the rest of the post mounting portion 57. However other features such as grooves, ridges, protrusions, slots, holes, keyways, bumps, nubs, dimples, crests, rims, or other like structural features may be included. In addition, the connector body 50 may include an outer annular recess 58 located proximate or near the first end 51 of the connector body 50. Furthermore, the connector body 50 may include a semi-rigid, yet compliant outer surface 55, wherein the outer surface 55 may be configured to form an annular seal when the second end 52 is deformably compressed against a received coaxial cable 10 by operation of a compression portion 60. The connector body 50 may include an outer ramped surface 56 and an internal annular notch 59 or groove proximate the second end 52 to structurally facilitate the deformation of the connector body 50, as described in further detail infra.
Moreover, the connector body 50 may include an external annular detent located proximate or close to the second end 52 of the connector body 50. Further still, the connector body 50 may include internal surface features, such as annular serrations formed near or proximate the internal surface of the second end 52 of the connector body 50 and configured to enhance frictional restraint and gripping of an inserted and received coaxial cable 10, through tooth-like interaction with the cable. The connector body 50 may be formed of materials such as plastics, polymers, bendable metals or composite materials that facilitate a semi-rigid, yet compliant outer surface 55. Further, the connector body 50 may be formed of conductive or non-conductive materials or a combination thereof. Manufacture of the connector body 50 may include casting, extruding, cutting, turning, drilling, knurling, injection molding, spraying, blow molding, component overmolding, combinations thereof, or other fabrication methods that may provide efficient production of the component.

An embodiment of an assembled configuration of connector 100 with respect to the sleeve 90a may involve sliding the sleeve 90a over the coupling member 30a in an axial direction starting from the first end 31a and continuing toward the second end 32a of the coupling member 30a until sufficient mating and/or engagement occurs between the engagement member 97a of the sleeve 90a and the retaining structure 37a of the coupling member 30a, as shown in
Embodiments of connector 100 may include a compression portion 60. Compression portion 60 may be operably attached to the connector body 50. For instance, the compression portion 60 may be structurally integral with the connector body 50, wherein the compression portion 60 separates or shears from the connector body 50 upon an axial force which in turn radially compresses the second end 52 of the connector body 50 onto the coaxial cable 10, as shown in
Furthermore, embodiments of connector 100 may include a radial restriction member 65a. The radial restriction member 65a may be a bushing or similar annular tubular member disposed proximate the rearward second end 52 of the connector body 50. For instance, the radial restriction member 65a may surround the compression portion 60 and a portion of the connector body 50 proximate the rearward second end 52. The radial restriction member 65a may be a generally annular, hollow cylindrically-shaped sleeve-like member comprised of stainless steel or other substantially rigid materials which may structurally assist the crack and seal process of compression portion 60. For instance, when the compression portion 60 is axially compressed in a direction towards the coupling member 30, the radial restriction member 65a may axially displace along with the compression portion 60 and may prevent the compression portion 60 from splintering or otherwise displacing in a direction other than substantially axial towards the coupling member 30.
Embodiments of the compression portion 60 may create an environmental seal around the coaxial cable 10 when in the fully compressed position. Specifically, when the compression portion 60 (and the radial restriction member 65a) is axially slid or compressed towards the coupling member 30, the structural connection between the compression portion 60 and the connector body 50 is severed, sheared, ruptured, etc., and the compression portion 60 comes into contact with the outer ramped surface 56 of the connector body 50. The severing of the structural connection between the connector body 50 and the compression portion 60 essentially turns the internal notch 66a into a cooperative ramped surface with the outer ramped surface 56 of the connector body 50. Due to the cooperative ramped surfaces, the axial compression (displacement) of the compression portion 60 evenly compresses the second end 52 of the connector body 50 onto the outer jacket 12 of the coaxial cable 10 and deforms the outer ramped surface 56, as shown in

Embodiments of a connector 103 may include a coupling member 30b. Coupling member 30b may share the same or substantially the same structural and functional aspects of coupling member 30a. Accordingly, coupling member 30b has a first forward end 31b, an opposing second rearward end 32b, internal threading 33b, an internal lip 34b including a surface 35b facing the first forward end 31b of the coupling member 30b. However, the second rearward end 32b, of the coupling member 30b may extend a significant axial distance to reside radially extent, or otherwise partially surround, a portion of the connector body 50, although the extended portion of the coupling member 30b need not contact the connector body 50. Additionally, coupling member 30b may include a retaining structure 37b on an outer surface 36b of the coupling member 30b. The retaining structure 37b may share the same or substantially same structural and functional aspects of the retaining structure 37a described in association with, for example, connector 100. Manufacture of the coupling member 30b may include casting, extruding, cutting, knurling, turning, tapping, drilling, injection molding, blow molding, combinations thereof, or other fabrication methods that may provide efficient production of the component. The forward facing surface 35b of the coupling member 30b faces a flange 44 the post 40 when operably assembled in a coaxial cable connector, so as to allow the coupling member 30b to rotate with respect to the other component elements, such as the post 40 and the connector body 50.
Embodiments of connector 103 may include an outer sleeve 90b. Sleeve 90b may share the same structural and functional aspects of sleeve 90a described in association with, for example, connector 100. Accordingly, sleeve 90b may include an engagement member 97b that is configured to mate or engage with a retaining structure 37b of the coupling member 30b. For example, the sleeve 90b may include a first end 91b, a second end 92b, an inner surface 93b, and an outer surface 94b, and may be a generally annular member having a generally axial opening therethrough. However, the sleeve 90b may be radially disposed over the coupling member 30b, or a portion thereof, the connector body 50, or a portion thereof, the compression portion 60, or a portion thereof, and the radial restriction member 65, while operably assembled and/or in a compressed position. Additionally, the sleeve 90b may include an annular ramped surface 95b or chamfer proximate or otherwise near the first end 91b to accommodate an increased diameter or general size of the coupling member 30b proximate a second, rearward end 32b of the coupling member 30b. Embodiments of the ramped surface 95b may be structurally integral with the engagement member 97b and the body of the sleeve 90b. Furthermore, embodiments of an assembled configuration of connector 103 with respect to the sleeve 90b may involve sliding the sleeve 90b over the coupling member 30b in an axial direction starting from the first end 31b and continuing toward the second end 32b of the coupling member 30b until sufficient mating and/or engagement occurs between the engagement member 97b of the sleeve 90b and the retaining structure 37b of the coupling member 30b, as shown in

Embodiments of connector 106 may include an integral sleeve 90c. An integral sleeve 90c may be a generally annular member having a generally axial opening therethrough. The integral sleeve 90c may include a first end 91c, a second end 1392c, an outer surface 93c, and an outer surface 94c. Furthermore, the integral sleeve 90c may include a coupling portion 95c proximate the first end 91c and a body portion 96c structurally integral with the coupling portion 95c. The coupling portion 95c may include internal threads for operable engagement with an interface port, such as interface port 20. For instance, the internal threads of the coupling portion 95c of the integral sleeve 90c may correspond to threads on the outer surface of an interface port. The coupling portion 95c may also include an internal lip 97c, such as an annular protrusion. The internal lip 97c includes a surface 98c facing the first forward end 91c of the integral sleeve 90c. The forward facing surface 98c of the lip 97c may be a tapered surface that corresponds to a tapered surface 45 of the post 40. The forward facing surface 98c of the coupling portion 95c faces the flange 44 of the post 40 when operably assembled in a connector 106, so as to allow the integral sleeve 90c to rotate with respect to the other component elements, such as the post 40 and the connector body 50. The structural configuration of the coupling portion 95c of integral sleeve 90c may vary according to differing connector design parameters to accommodate different functionality of a coaxial cable connector. For instance, the first forward end 91c of the integral sleeve 90c may include internal and/or external structures such as ridges, grooves, curves, detents, slots, openings, chamfers, or other structural features, etc., which may facilitate the operable joining of an environmental sealing member, such a water-tight seal or other attachable component element, that may help prevent ingress of environmental contaminants, such as moisture, oils, and dirt, at the first forward end 91c of the integral sleeve 90c, when mated with an interface port 20. Those in the art should appreciate that the coupling portion 95c need not be threaded.
Moreover, the integral sleeve 90c includes a body portion 96c that may be structurally integral with the coupling portion 95c to form an outer sleeve that may surround the post 40, the connector body 50, the compression portion 60, or a portion thereof, and the radial restriction member 65, or a portion thereof when in an assembled and/or compressed position. Because the body portion 96c may be structurally integral with the coupling portion 95c, rotation or twisting of the body portion 96c can cause rotation or twisting of the coupling portion 95c to operably mate a coaxial cable connector, such as connector 106, onto an interface port. Thus, the integral sleeve 90c includes a larger surface area to grip and twist the integral sleeve 90c to thread the coupling portion 95c fully onto the interface port, such as interface port 20. Embodiments of the body portion 96c of the integral sleeve 90c may include outer surface features, such as annular serrations or slots, configured to enhance gripping of the integral sleeve 90c while connecting the coaxial cable connector onto an interface port. The body portion 96c of the sleeve 90c may be formed of materials such as plastics, polymers, bendable metals or composite materials that facilitate a rigid body, while the coupling portion 95c may be formed of conductive materials, such as copper, brass, aluminum, or other metals or metal alloys, facilitating grounding through the connector. In other words, the integral sleeve 90c may be formed of both conductive and non-conductive materials. For example, the external surface of the coupling portion 95c of the integral sleeve 90c may be formed of a polymer, while the remainder of the coupling portion 95c may be comprised of a metal or other conductive material. Alternatively, the coupling portion 95c and the body portion 96c of the integral sleeve 90c may be formed of conductive materials such as metals or metal alloys, or may both be formed of polymers or other materials that would facilitate a rigidly formed component. Manufacture of the integral sleeve 90c may include casting, extruding, cutting, knurling, turning, tapping, drilling, injection molding, blow molding, combinations thereof, or other fabrication methods that may provide efficient production of the component.

The seal-grasping surface portion 36c may be a flat, smooth surface or a flat, roughened surface suitable to frictionally and/or adhesively engage an interior sealing surface 83 of the sealing member 80. Embodiments of the seal-grasping surface portion 36c may also contain a ridge that together with the seal grasping surface portion 36c forms a groove or shoulder that is suitably sized and shaped to correspondingly engage an internal shoulder 87 of the sealing member 80 adjacent the interior sealing surface 83 in a locking-type interference fit between the coupling member 30c and the sealing member 80.
Moreover, the coupling member 30c may further include a coupling member-turning surface portion on an outer surface 84 of the sealing member 80. The coupling member-turning surface portion may have at least two flat surface regions that allow engagement with the surfaces of a tool such as a wrench. In one embodiment, the coupling member-turning surface is hexagonal. Alternatively, the coupling member-turning surface may be a knurled surface to facilitate hand-turning of the nut component. Furthermore, upon engagement of the sealing member 80 with the coupling member 30c, a rear sealing surface of the sealing member 80 abuts a side/edge surface of the coupling member 30c to form a sealing relationship in that region. In one embodiment, the connector-grasping portion 36c of the coupling member 30c is an internally-projecting shoulder that engages a flange 44 of the post 40 in such a manner that the coupling member 30c can be freely rotated as it is held in place as part of the connector.

However, sleeve 90g may include an inwardly extending lip 97g proximate or otherwise near the first end 91g of the sleeve 90g, which can help guide the coupling member 30b onto a corresponding interface port. The lip 97g may share the same structural and functional aspects of the engagement member 97b. For instance, the lip 97g may radially inwardly extend a distance sufficient to prevent axial movement of the sleeve 90g in a direction towards the second end 32b of the coupling member 30b when operably assembled and/or in a compressed position. An embodiment of an assembled configuration of connector 115 with respect to the sleeve 90g may involve sliding the sleeve 90g over the coupling member 30b in an axial direction starting from the first end 31b and continuing toward the second end 32b of the coupling member 30b until sufficient mechanical interference and/or engagement occurs between the lip 97g of the sleeve 90g and frontal edge or mating surface of the coupling member 30b.

Sleeve 90e may surround the coupling member 30a, the post 40, the connector body 50, or a portion thereof, the compression portion 60, and a radial restriction member 65, or a portion thereof when in an assembled and/or compressed position. Moreover, the sleeve 90e may extend towards the first end 31a of coupling member 30a. However, sleeve 90e may include an inwardly extending lip 97e proximate or otherwise near the first end 91e of the sleeve 90e, which can help guide the coupling member 30a onto a corresponding interface port. The lip 97e may share the same functional aspects of the engagement member 97a, 97d of sleeve 90a, 90d, respectively. For instance, the lip 97e may radially inwardly extend a distance sufficient to prevent axial movement of the sleeve 90e in a direction towards the second end 32a of the coupling member 30a when operably assembled and/or in a compressed position. An embodiment of an assembled configuration of connector 121 with respect to the sleeve 90e may involve sliding the sleeve 90e over the coupling member 30a in an axial direction starting from the first end 31a and continuing toward the second end 32a of the coupling member 30a until sufficient mechanical interference and/or engagement occurs between the lip 97e of the sleeve 90e and frontal edge or mating surface of the coupling member 30a. The simultaneous rotation/twisting of the sleeve 90e and the coupling member 30a may be effectuated in the same or similar manner as described between the sleeve 90a and the coupling member 30a.

Embodiments of connector 127 may include a compression portion 260b. Compression portion 260b may be a fastener member that is inserted over the connector body 50 to deformably compress the connector body 50 onto the cable 10. The compression portion 260b may have a first end 261 and opposing second end 262. In addition, the compression portion 260 may include an internal annular protrusion 263 located proximate the first end 261 of the compression portion 260b and configured to mate and achieve purchase with the annular detent 53 on the outer surface 55 of connector body 50. Moreover, the compression portion 260b may comprise a central passageway defined between the first end 261 and second end 262 and extending axially through the compression portion 260b. The central passageway may comprise a ramped surface 266 which may be positioned between a first opening or inner bore having a first diameter positioned proximate with the first end 261 of the compression portion 260b and a second opening or inner bore having a second diameter positioned proximate with the second end 262 of the compression portion 260b. The ramped surface 266 may act to deformably compress the outer surface 55 of a connector body 50 when the compression portion 260b is operated to secure a coaxial cable 10. For example, the narrowing geometry will compress squeeze against the cable, when the compression portion is compressed into a tight and secured position on the connector body. Additionally, the compression portion 260b may comprise an exterior surface feature 269 positioned proximate with or close to the second end 262 of the compression portion 260b. The surface feature 269 may facilitate gripping of the compression portion 260b during operation of the connector. Although the surface feature 269 is shown as an annular detent, it may have various shapes and sizes such as a ridge, notch, protrusion, knurling, or other friction or gripping type arrangements. It should be recognized, by those skilled in the requisite art, that the compression portion 260b may be formed of rigid materials such as metals, hard plastics, polymers, composites and the like, and/or combinations thereof. Furthermore, the compression portion 260b may be manufactured via casting, extruding, cutting, turning, drilling, knurling, injection molding, spraying, blow molding, component overmolding, combinations thereof, or other fabrication methods that may provide efficient production of the component.
Embodiments of connector 128 may include a compression portion 260c. Compression portion 260c may be an insertable compression sleeve or tubular locking compression member that resides internally with respect to the connector body 50 in the compressed position. The compression portion 260c may include a first end 261c, a second end 262c, an inner surface 263, and an outer surface 264c. The compression portion 260c may be pushed into the connector body 50 to squeeze against and secure the cable 10. For instance, the compression portion 260c may protrude axially into an annular chamber through the rear opening, and may be slidably coupled or otherwise movably affixed to the connector body 50 to compress into the connector body 50 and retain the cable 10. The compression portion 260c may be displaceable or movable axially or in the general direction of the axis of the connector between a first open position (accommodating insertion of the tubular inner post 40 into a prepared cable 10 end to contact the grounding shield 14), and a second clamped position compressibly fixing the cable 10 within the chamber of the connector because the compression portion 260c is squeezed into retraining contact with the cable 10 within the connector body 50. Furthermore, the compression portion 260c may include a lip 265c proximate the first end 261c, wherein the lip 265c of the compression portion 260c mates with the internal groove of the connector body 50.
Further embodiments of a coaxial cable connector may include a coupling member 30, a post 40, a connector body 50, a sealing member 80, a connector body seal member 5, a sleeve 90, a compression portion 60/260, and a radial restriction member 65a/65b/65c. Embodiments of sleeve 90 may include sleeve 90a/90b/90d/90e/90f/90g/90h, or may simply share the same structural and functional aspects, yet be configured to operably attach to a coupling member having molded plastic threads, or a coupling member that is completely molded. Embodiments of a coupling member 30, which may share the same or substantially the same structural and functional aspects of 30a/30b/30c, may include plastic threads designed to seal against the external threads 23 of port 20 to keep moisture and other physical contaminants out. For example, the threads may be cut slightly different resulting in a differently shaped or dimensioned thread from the threads 23 of the port 20 to achieve a seal with the port 20. Furthermore, the threads could be slightly over-sized causing the metallic threads 23 of the port 20 to slice, pierce, grind, etc., into and against the plastic threads of the plastic coupling member 30 as the plastic coupling member 30 is being threaded onto the port 20. The threads can be molded or machined, and the coupling member 30 can be all plastic (molded or machined) or the coupling member 30 can have a plastic insert that has molded or cut threads. Additionally, the plastic threads may be shaped like pipe-threads causing the non-pipe-thread-shaped threads of the port 20 to seal against the plastic threads of the coupling member 30 when the coupling member 30 is advanced onto the port 20. The threads may also include a small protrusion feature running along the threads that forms a seal with the threads of the port 20 as the coupling member 30 is advanced onto the port 20. Embodiments of a plastic coupling member (or partially plastic coupling member having plastic threads), in addition to creating a physical seal, may inherently create a secure connection to the port 20 because a tight friction-fit may likely be formed with the port 20 as the threads of the coupling member 30 are advanced (with some amount of force that may be necessary to overcome the friction) onto the threads of the port 20.
Those skilled in the art should appreciate that various combinations and embodiments disclosed and described in detail herein may include a body seal element, such as connector body seal element 5, to provide an environmental seal for the coaxial cable connector.

Embodiments of connector 2000 may include a connector body 2050. The connector body 2050 may comprise a first end 2051 and opposing second end 2052. Moreover, the connector body 2050 may include a post mounting portion 2057 proximate or otherwise near the first end 2051 of the body 2050, the post mounting portion 2057 configured to securely locate the body 2050 relative to a portion of the outer surface of post 2040, so that the connector body 2050 is axially secured with respect to the post 2040, in a manner that prevents the two components from moving with respect to each other in a direction parallel to the axis of the connector 2000. The internal surface of the post mounting portion 2057 may include an engagement feature, such as an annular detent or ridge having a different diameter than the rest of the post mounting portion 207. However other features such as grooves, ridges, protrusions, slots, holes, keyways, bumps, nubs, dimples, crests, rims, or other like structural features may be included. In addition, the connector body 2050 may include an outer annular recess 2058 located proximate or near the first end 2051 of the connector body 2050. Furthermore, the connector body 2050 may include a semi-rigid, yet compliant outer surface 2055, wherein the second end 2052 of the connector body 2050 may be configured to form an annular seal when the second end 2052 is deformably compressed against a received coaxial cable 10 by operation of a compression portion 2060. The connector body 2050 may include an outer ramped surface 2056 to gradually reduce thickness of the connector body 2050 proximate the second end 2052 and define a weakened annular portion with a cooperating internal annular groove 2066 of the compression portion 2060. Further embodiments of connector body 2050 may include an internal annular notch 2059 or groove located an axial distance towards the coupling member 2030 from the internal annular groove 2066 of the compression portion 2060 to structurally facilitate the deformation of the connector body 2050, as described in further detail infra.
Moreover, the connector body 2050 may include an external annular detent 2071 located proximate or close to the second end 2052 of the connector body 2050. The external annular detent 2071 may be configured to receive, mate with, engage with, and/or cooperate with an internal lip 2081 of a radial restriction member 2065. Embodiments of the external annular detent 2071 may include a ramped portion 2072 and a lip portion 2073. The ramped portion 2072 of the external detent 2071 may facilitate smooth or otherwise gradient axial movement of the radial restriction member 2065 towards the coupling member 30 as the radial restriction member 2065 and the compression 2060 are being axially compressed. The lip portion 2073 may form a wall or similar edge that is perpendicular or substantially perpendicular to the outer surface 2055 of the connector body 2050. The location and structure of the lip portion 2073 of the external annular detent 2071 may prevent or interfere with axial movement of the radial restriction member 2065 in a direction away from the coupling member 30, which could result in the radial restriction member 2065 sliding off of the connector 2000. In other words, the radial restriction member 2065 may operably engage the connector body 2050 when the internal lip 2081 of the radial restriction member 2065 snaps into place or cooperates with the external annular detent 2071 of the connector body 2050. Further still, the connector body 2050 may include internal surface features, such as annular serrations formed near or proximate the internal surface of the second end 2052 of the connector body 2050 and configured to enhance frictional restraint and gripping of an inserted and received coaxial cable 10, through tooth-like interaction with the cable. The connector body 2050 may be formed of materials such as plastics, polymers, bendable metals or composite materials that facilitate a semi-rigid, yet compliant outer surface 2055. Further, the connector body 2050 may be formed of conductive or non-conductive materials or a combination thereof. Manufacture of the connector body 50 may include casting, extruding, cutting, turning, drilling, knurling, injection molding, spraying, blow molding, component overmolding, combinations thereof, or other fabrication methods that may provide efficient production of the component.
Embodiments of connector 2000 may include a compression portion 2060. Compression portion 2060 may be operably attached to the connector body 2050 through a frangible connection 2090. For instance, the compression portion 2060 may be structurally integral with the connector body 2050, wherein the compression portion 2060 separates or shears from the connector body 2050 upon an axial force which in turn radially compresses the second end 2052 of the connector body 2050 onto the coaxial cable 10, as shown in
Embodiments of the compression portion 2060 may include a first outer ramped surface 2092 proximate the frangible connection 2090. The first outer ramped surface 2092 of the compression portion 2060 may help to gradually reduce the thickness of the compression portion proximate the frangible connection 2090; furthermore, the first outer ramped surface 2092 may also provide a small amount of space for the compression portion 2060 to more efficiently and smoothly ride up along the outer ramped surface 2056 of the connector body 2050 during compression of the compression portion 2060. Further still, embodiments of the compression portion 2060 may include a second outer ramped surface 2093 at an opposing end of the compression portion 2060 from the first outer ramped portion 2092. The second outer ramped portion 2093 may extend less axial distance than the first outer ramped surface 2092, and may provide some clearance or leeway for the radial restriction member 2065 when being compressed. The annular notch 2059 of the connector body 2050 located an axial distance from the internal annular notch 2066 may further facilitate the deformation of the second end 2052 of the connector body 2050.
Additionally, the frangible connection 2090 may be located at an axial distance along the connector 2000 just prior to, proximate, or otherwise near the single barb 2049 on the second end of the post 2040 to allow for compression of the second end 2052 of the connector body 2050 onto the cable 10 at a location where the grounding shield 14 and jacket 12 bulge out from engagement with the annular barb 2049. If the grounding shield 14 and jacket 12 of the cable 10 are radially displaced outward based on engagement with the single, annular barb 2049 of the post 2040, then the second end 2052 of the connector body 2050 can exert more force against the shield 14 and jacket 12 to enhance the seal created around the cable 10 proximate the rear end of the connector 2000. Embodiments of the compression portion 2060 may be formed of the same material as connector body 2050 because they may be structurally integral with each other. For example, the compression portion 2060 may be comprised of materials such as plastics, polymers, bendable metals or composite materials that facilitate a rigid body. Further, the compression portion 2060 may be formed of conductive or non-conductive materials or a combination thereof. Manufacture of the compression member 2060 may include casting, extruding, cutting, turning, drilling, knurling, injection molding, spraying, blow molding, component overmolding, combinations thereof, or other fabrication methods that may provide efficient production of the component.
Furthermore, embodiments of connector 2000 may include a radial restriction member 2065. The radial restriction member 2065 may be a sleeve or similar annular tubular member disposed proximate the rearward second end 2052 of the connector body 2050. For instance, the radial restriction member 2065 may surround the compression portion 2060 and a portion of the connector body 2050 proximate the rearward second end 2052. Embodiments of the radial restriction member 2065 may include an engagement surface for operable engagement with a compression tool. For instance, embodiments of the radial restriction member 2065 may include an internal annular lip 2063 or inwardly extending flange proximate a rearward end 2062 of the radial restriction member 2065. The lip 2063 may radially inwardly extend a distance to cover about half of the thickness of the compression portion 2060. The radial restriction member 2065 may surround or partially surround the compression portion 2060 and a portion of the connector body 2050 proximate the rearward second end 2052, wherein the internal annular lip 2063 of the radial restriction member 2065 may be configured to contact the compression portion 2060 prior to or upon axial compression of the connector. Additionally, the internal lip 2063 proximate the rearward end 2062 of the radial restriction member 2065 may provide an engagement surface for operable engagement with a compression tool, or other device/means that provides the necessary compression to compress seal connector 2000. The radial restriction member 2065 may be a generally annular, hollow cylindrically-shaped sleeve-like member comprised of stainless steel or other substantially rigid materials which may structurally assist the crack and seal process of compression portion 2060. For instance, when the compression portion 2060 is axially compressed in a direction towards the coupling member 2030, the radial restriction member 2065 may axially displace along with the compression portion 2060 and may prevent the compression portion 2060 from splintering or otherwise displacing in a direction other than substantially axial towards the coupling member 2030. Furthermore, the axial length of the radial restriction member 2065 may vary, but when in the uncompressed position, a forward end 2061 of the radial restriction member 2065 may terminate a distance just beyond (towards coupling member 2030) the external annular detent 2071, sufficient to allow the radial restriction member 2065 to securably attach to the connector body 2050. Embodiments of the radial restriction member 2065 may be a radial restriction member sharing the same or substantially the same structure and function of the radial restriction member 65a, and 65b described supra.
Embodiments of the compression portion 2060 may create an environmental seal around the coaxial cable 10 when in the fully compressed position (shown in
