Description

FIELD OF TECHNOLOGY

The following relates to connectors used in coaxial cable communication applications, and more specifically to embodiments of a connector having a biasing member for maintaining continuity through a connector.

BACKGROUND

Connectors for coaxial cables are typically connected onto complementary interface ports to electrically integrate coaxial cables to various electronic devices. Maintaining continuity through a coaxial cable connector typically involves the continuous contact of conductive connector components which can prevent radio frequency (RF) leakage and ensure a stable ground connection. In some instances, the coaxial cable connectors are present outdoors, exposed to weather and other numerous environmental elements. Weathering and various environmental elements can work to create interference problems when metallic conductive connector components corrode, rust, deteriorate or become galvanically incompatible, thereby resulting in intermittent contact, poor electromagnetic shielding, and degradation of the signal quality. Moreover, some metallic connector components can permanently deform under the torque requirements of the connector mating with an interface port. The permanent deformation of a metallic connector component results in intermittent contact between the conductive components of the connector and a loss of continuity through the connector.

Thus, a need exists for an apparatus and method for ensuring continuous contact between conductive components of a connector.

US 2010/297875 A1 discloses a coaxial cable connector comprising: a post having a first end, a second end, and a flange proximate the second end, wherein the post is configured to receive a center conductor surrounded by a dielectric of a coaxial cable, wherein the post is configured to extend along a general axis; a coupling element configured to be rotatably secured to the post to allow for rotational movement about the post, wherein the coupling element has a first end, a second end and an internal lip; and a connector body configured to engage the post and receive the coaxial cable when the coaxial cable connector is assembled, the connector body including a biasing element having resiliency; and wherein the deflection enables the biasing element to provide a biasing force to effectuate contact between the internal lip of the coupling element and the flange of the post to promote electrical continuity through the coaxial cable connector even when the coaxial connector is not fully tightened onto an interface port.

US 2009/186521 A1 discloses a coaxial connector with a connector body having a groove which allows an edge portion of the body to deflect.

DETAILED DESCRIPTION

A detailed description of the hereinafter described embodiments of the disclosed apparatus and method are presented herein by way of exemplification and not limitation with reference to the Figures. Although certain embodiments are shown and described in detail, it should be understood that various changes and modifications may be made without departing from the scope of the appended claims. The scope of the present disclosure will in no way be limited to the number of constituting components, the materials thereof, the shapes thereof, the relative arrangement thereof, etc., and are disclosed simply as an example of embodiments of the present disclosure.

As a preface to the detailed description, it should be noted that, as used in this specification and the appended claims, the singular forms "a", "an" and "the" include plural referents, unless the context clearly dictates otherwise.

Referring to the drawings, FIG. 1 depicts an example of a coaxial cable connector 100 which does not form part of the invention but represents background art that is useful for understanding the invention. A coaxial cable connector 100 has a first end 1 and a second end 2, and can be provided to a user in a preassembled configuration to ease handling and installation during use. Coaxial cable connector 100 may be an F connector, or similar coaxial cable connector. Furthermore, the connector 100 includes a post 40 configured for receiving a prepared portion of a coaxial cable 10.

Referring now to FIG.2, the coaxial cable connector 100 may be operably affixed to a prepared end of a coaxial cable 10 so that the cable 10 is securely attached to the connector 100. The coaxial cable 10 may include a center conductive strand 18, surrounded by an interior dielectric 16; the interior dielectric 16 may possibly be surrounded by a conductive foil layer; the interior dielectric 16 (and the possible conductive foil layer) is surrounded by a conductive strand layer 14; the conductive strand layer 14 is surrounded by a protective outer jacket 12a, wherein the protective outer jacket 12 has dielectric properties and serves as an insulator. The conductive strand layer 14 may extend a grounding path providing an electromagnetic shield about the center conductive strand 18 of the coaxial cable 10. The coaxial cable 10 may be prepared by removing the protective outer jacket 12 and drawing back the conductive strand layer 14 to expose a portion of the interior dielectric 16 (and possibly the conductive foil layer that may tightly surround the interior dielectric 16) and center conductive strand 18. The protective outer jacket 12 can physically protect the various components of the coaxial cable 10 from damage which may result from exposure to dirt or moisture, and from corrosion. Moreover, the protective outer jacket 12 may serve in some measure to secure the various components of the coaxial cable 10 in a contained cable design that protects the cable 10 from damage related to movement during cable installation. However, when the protective outer jacket 12 is exposed to the environment, rain and other environmental pollutants may travel down the protective outer jack 12. The conductive strand layer 14 can be comprised of conductive materials suitable for carrying electromagnetic signals and/or providing an electrical ground connection or electrical path connection. The conductive strand layer 14 may also be a conductive layer, braided layer, and the like. Various examples of the conductive strand layer 14 may be employed to screen unwanted noise. For instance, the conductive strand layer 14 may comprise a metal foil (in addition to the possible conductive foil) wrapped around the dielectric 16 and/or several conductive strands formed in a continuous braid around the dielectric 16. Combinations of foil and/or braided strands may be utilized wherein the conductive strand layer 14 may comprise a foil layer, then a braided layer, and then a foil layer. Those in the art will appreciate that various layer combinations may be implemented in order for the conductive strand layer 14 to effectuate an electromagnetic buffer helping to prevent ingress of environmental noise or unwanted noise that may disrupt broadband communications. In some examples, there may be flooding compounds protecting the conductive strand layer 14. The dielectric 16 may be comprised of materials suitable for electrical insulation. The protective outer jacket 12 may also be comprised of materials suitable for electrical insulation. It should be noted that the various materials of which all the various components of the coaxial cable 10 should have some degree of elasticity allowing the cable 10 to flex or bend in accordance with traditional broadband communications standards, installation methods and/or equipment. It should further be recognized that the radial thickness of the coaxial cable 10, protective outer jacket 12, conductive strand layer 14, possible conductive foil layer, interior dielectric 16 and/or center conductive strand 18 may vary based upon generally recognized parameters corresponding to broadband communication standards and/or equipment.

Furthermore, environmental elements that contact conductive components, including metallic components, of a coaxial connector may be important to the longevity and efficiency of the coaxial cable connector (i.e. preventing RF leakage and ensuring stable continuity through the connector 100). Environmental elements may include any environmental pollutant, any contaminant, chemical compound, rainwater, moisture, condensation, stormwater, polychlorinated biphenyl's (PCBs), contaminated soil from runoff, pesticides, herbicides, and the like. Environmental elements, such as water or moisture, may corrode, rust, degrade, etc. connector components exposed to the environmental elements. Thus, metallic conductive O-rings utilized by a coaxial cable connector that may be disposed in a position of exposure to environmental elements may be insufficient over time due to the corrosion, rusting, and overall degradation of the metallic O-ring.

Referring back to FIG. 1, the connector 100 may mate with a coaxial cable interface port 20. The coaxial cable interface port 20 includes a conductive receptacle 22 for receiving a portion of a coaxial cable center conductor 18 sufficient to make adequate electrical contact. The coaxial cable interface port 20 may further comprise a threaded exterior surface 24. However, various examples may employ a smooth surface, as opposed to threaded exterior surface. In addition, the coaxial cable interface port 20 may comprise a mating edge 26. It should be recognized that the radial thickness and/or the length of the coaxial cable interface port 20 and/or the conductive receptacle 22 may vary based upon generally recognized parameters corresponding to broadband communication standards and/or equipment. Moreover, the pitch and depth of threads which may be formed upon the threaded exterior surface 24 of the coaxial cable interface port 20 may also vary based upon generally recognized parameters corresponding to broadband communication standards and/or equipment. Furthermore, it should be noted that the interface port 20 may be formed of a single conductive material, multiple conductive materials, or may be configured with both conductive and non-conductive materials corresponding to the port's 20 electrical interface with a coaxial cable connector, such as connector 100. For example, the threaded exterior surface may be fabricated from a conductive material, while the material comprising the mating edge 26 may be non-conductive or vice versa. However, the conductive receptacle 22 should be formed of a conductive material. Further still, it will be understood by those of ordinary skill that the interface port 20 may be embodied by a connective interface component of a communications modifying device such as a signal splitter, a cable line extender, a cable network module and/or the like.

Referring further to FIG. 1, examples of a connector 100 may include a post 40, a coupling element 30, a connector body 50, a fastener member 60, and a biasing member 70. Examples of connector 100 may also include a post 40 having a first end 41, a second end 42, and a flange 45 proximate the second end 42, wherein the post 40 is configured to receive a center conductor 18 surrounded by a dielectric 16 of a coaxial cable 10, a connector body 50 attached to the post 40, a coupling element 30 attached to the post 40, the coupling element 30 having a first end 31 and a second end 32, and a biasing member 70 disposed within a cavity 38 formed between the first end 31 of the coupling element 30 and the connector body 50 to bias the coupling element 30 against the post 40.

Examples of connector 100 may include a post 40, as further shown in FIG. 3.

The post 40 comprises a first end 41, a second end 42, an inner surface 43, and an outer surface 44. Furthermore, the post 40 may include a flange 45, such as an externally extending annular protrusion, located proximate or otherwise near the second end 42 of the post 40. The flange 45 may include an outer tapered surface 47 facing the first end 41 of the post 40 (i.e. tapers inward toward the first end 41 from a larger outer diameter proximate or otherwise near the second end 42 to a smaller outer diameter. The outer tapered surface 47 of the flange 45 may correspond to a tapered surface of the lip 36 of the coupling element 30. Further still, an example of the post 40 may include a surface feature 49 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 may not include such a surface feature 49, and the coaxial cable connector 100 may rely on press-fitting and friction-fitting forces and/or other component structures to help retain the post 40 in secure location both axially and rotationally relative to the connector body 50. The location proximate or otherwise near where the connector body 50 is secured relative to the post 40 may include surface features, such as ridges, grooves, protrusions, or knurling, which may enhance the secure location of the post 40 with respect to the connector body 50. Additionally, the post 40 includes 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. The post 40 should be formed such that portions of a prepared coaxial cable 10 including the dielectric 16 and center conductor 18 can pass axially into the first end 41 and/or through a portion of the tube-like body of the post 40. Moreover, the post 40 should be dimensioned such that the post 40 may be inserted into an end of the prepared coaxial cable 10, around the dielectric 16 and under the protective outer jacket 12 and conductive grounding shield or strand 14. Accordingly, where an embodiment of the post 40 may be inserted into an end of the prepared coaxial cable 10 under the drawn back conductive strand 14, substantial physical and/or electrical contact with the strand layer 14 may be accomplished thereby facilitating grounding through the post 40. The post 40 may be formed of metals or other conductive materials that would facilitate a rigidly formed post body. In addition, the post 40 may be formed of a combination of both conductive and non-conductive materials. For example, a metal coating or layer may be applied to a polymer of other non-conductive material. Manufacture of the post 40 may include casting, extruding, cutting, turning, drilling, knurling, injection molding, spraying, blow molding, component overmolding, or other fabrication methods that may provide efficient production of the component.

With continued reference to FIG. 1, and further reference to FIG. 4, examples of connector 100 may include a coupling element 30. The coupling element 30 may be a nut, a threaded nut, port coupling element, rotatable port coupling element, and the like. The coupling element 30 may include a first end 31, second end 32, an inner surface 33, and an outer surface 34. The inner surface 33 of the coupling element 30 may be a threaded configuration, the threads having a pitch and depth corresponding to a threaded port, such as interface port 20. In other examples, the inner surface 33 of the coupling element 30 may not include threads, and may be axially inserted over an interface port, such as port 20. The coupling element 30 may be rotatably secured to the post 40 to allow for rotational movement about the post 40. The coupling element 30 may comprise an internal lip 36 located proximate the first end 31 and configured to hinder axial movement of the post 40. Furthermore, the coupling element 30 may comprise a cavity 38 extending axially from the edge of first end 31 and partial defined and bounded by the internal lip 36. The cavity 38 may also be partially defined and bounded by an outer internal wall 39. The coupling element 30 may be formed of conductive materials facilitating grounding through the coupling element 30, or threaded nut. Accordingly the coupling element 30 may be configured to extend an electromagnetic buffer by electrically contacting conductive surfaces of an interface port 20 when a coaxial cable connector, such as connector 100, is advanced onto the port 20. In addition, the coupling element 30 may be formed of non-conductive material and function only to physically secure and advance a connector 100 onto an interface port 20. Moreover, the coupling element 30 may be formed of both conductive and non-conductive materials. For example the internal lip 36 may be formed of a polymer, while the remainder of the coupling element 30 may be comprised of a metal or other conductive material. In addition, the coupling element 30 may be formed of metals or polymers or other materials that would facilitate a rigidly formed body. Manufacture of the coupling element 30 may include casting, extruding, cutting, turning, tapping, drilling, injection molding, blow molding, or other fabrication methods that may provide efficient production of the component. Those in the art should appreciate the various of examples of the nut 30 may also comprise a coupler member, or coupling element, having no threads, but being dimensioned for operable connection to a corresponding interface port, such as interface port 20.

Referring still to FIG. 1, and additionally to FIG. 5, examples of a coaxial cable connector, such as connector 100, may include a connector body 50. The connector body 50 may include a first end 51, a second end 52, an inner surface 53, and an outer surface 54. Moreover, the connector body may include a post mounting portion 57 proximate or otherwise near the second end 52 of the body 50; the post mounting portion 57 configured to securely locate the body 50 relative to a portion of the outer surface 44 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. In addition, the connector body 50 may include an outer annular recess 56 located proximate or near the second end 52 of the connector body 50. Furthermore, the connector body 50 may include a semi-rigid, yet compliant outer surface 54, wherein the outer surface 54 may be configured to form an annular seal when the first end 51 is deformably compressed against a received coaxial cable 10 by operation of a fastener member 60. The connector body 50 may include an external annular detent 58 located along the outer surface 54 of the connector body 50. Further still, the connector body 50 may include internal surface features 59, such as annular serrations formed near or proximate the internal surface of the first end 51 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 54. 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.

With further reference to FIG. 1 and FIG. 6, examples of a coaxial cable connector 100 may include a fastener member 60. The fastener member 60 may have a first end 61, second end 62, inner surface 63, and outer surface 64. In addition, the fastener member 60 may include an internal annular protrusion 67 located proximate the second end 62 of the fastener member 60 and configured to mate and achieve purchase with the annular detent 58 on the outer surface 54 of connector body 50. Moreover, the fastener member 60 may comprise a central passageway or generally axial opening defined between the first end 61 and second end 62 and extending axially through the fastener member 60. The central passageway may include a ramped surface 66 which may be positioned between a first opening or inner bore having a first inner diameter positioned proximate or otherwise near the first end 61 of the fastener member 60 and a second opening or inner bore having a larger, second inner diameter positioned proximate or otherwise near the second end 62 of the fastener member 60. The ramped surface 66 may act to deformably compress the outer surface 54 of the connector body 50 when the fastener member 60 is operated to secure a coaxial cable 10. For example, the narrowing geometry will compress squeeze against the cable, when the fastener member 60 is compressed into a tight and secured position on the connector body 50. Additionally, the fastener member 60 may comprise an exterior surface feature 69 positioned proximate with or close to the first end 61 of the fastener member 60. The surface feature 69 may facilitate gripping of the fastener member 60 during operation of the connector 100. Although the surface feature 69 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. The second end 62 of the fastener member 60 may extend an axial distance so that, when the fastener member 60 is compressed into sealing position on the coaxial cable 100, the fastener member 60 touches or resides substantially proximate significantly close to the coupling element 30. It should be recognized, by those skilled in the requisite art, that the fastener member 60 may be formed of rigid materials such as metals, hard plastics, polymers, composites and the like, and/or combinations thereof. Furthermore, the fastener member 60 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.

Referring back to FIG. 1, examples of a coaxial cable connector 100 can include a biasing member 70. The biasing member 70 may be formed of a non-metallic material to avoid rust, corrosion, deterioration, and the like, caused by environmental elements, such as water. Additional materials the biasing member 70 may be formed of may include, but are not limited to, polymers, plastics, elastomers, elastomeric mixtures, composite materials, rubber, and/or the like and/or any operable combination thereof. The biasing member 70 may be a resilient, rigid, semi-rigid, flexible, or elastic member, component, element, and the like. The resilient nature of the biasing member 70 may help avoid permanent deformation while under the torque requirements when a connector 100 is advanced onto an interface port 20.

Moreover, the biasing member 70 may facilitate constant contact between the coupling element 30 and the post 40. For instance, the biasing member 70 may bias, provide, force, ensure, deliver, etc. the contact between the coupling element 30 and the post 40. The constant contact between the coupling element 30 and the post 40 promotes continuity through the connector 100, reduces/eliminates RF leakage, and ensures a stable ground through the connection of a connector 100 to an interface port 20 in the event the connector 100 is not fully tightened onto the port 20. To establish and maintain solid, constant contact between the coupling element 30 and the post 40, the biasing member 70 may be disposed behind the coupling element 30, proximate or otherwise near the second end 52 of the connector. In other words, the biasing member 70 may be disposed within the cavity 38 formed between the coupling element 30 and the annular recess 56 of the connector body 50. The biasing member 70 can provide a biasing force against the coupling element 30, which may axially displace the coupling element 30 into constant direct contact with the post 40. In particular, the disposition of a biasing member 70 in annular cavity 38 proximate the second end 52 of the connector body 50 may axially displace the coupling element 30 towards the post 40, wherein the lip 36 of the coupling element 30 directly contacts the outer tapered surface 47 of the flange 45 of the post 40. The location and structure of the biasing member 70 may promote continuity between the post 40 and the coupling element 30, but does not impede the rotational movement of the coupling element 30 (e.g. rotational movement about the post 40). The biasing member 70 may also create a barrier against environmental elements, thereby preventing environmental elements from entering the connector 100. Those skilled in the art would appreciate that the biasing member 70 may be fabricated by extruding, coating, molding, injecting, cutting, turning, elastomeric batch processing, vulcanizing, mixing, stamping, casting, and/or the like and/or any combination thereof in order to provide efficient production of the component.

Examples of biasing member 70 may include an annular or semi-annular resilient member or component configured to physically and electrically couple the post 40 and the coupling element 30. One example of the biasing member 70 may be a substantially circinate torus or toroid structure, or other ring-like structure having a diameter (or cross-section area) large enough that when disposed within annular cavity 38 proximate the annular recess 56 of the connector body 50, the coupling element 30 is axially displaced against the post 40 and/or biased against the post 40. Moreover, examples of the biasing member 70 may be an O-ring configured to cooperate with the annular recess 56 proximate the second end 52 of connector body 50 and the outer internal wall 39 and lip 36 forming cavity 38 such that the biasing member 70 may make contact with and/or bias against the annular recess 56 (or other portions) of connector body 50 and outer internal wall 39 and lip 36 of coupling element 30. The biasing between the outer internal wall 39 and lip 36 of the coupling element 30 and the annular recess 56, and surrounding portions, of the connector body 50 can drive and/or bias the coupling element 30 in a substantially axial or axial direction towards the second end 2 of the connector 100 to make solid and constant contact with the post 40. For instance, the biasing member 70 should be sized and dimensioned large enough (e.g. oversized O-ring) such that when disposed in cavity 38, the biasing member 70 exerts enough force against both the coupling element 30 and the connector body 50 to axial displace the coupling element 30 a distance towards the post 40. Thus, the biasing member 70 may facilitate grounding of the connector 100, and attached coaxial cable 10 (shown in FIG. 2), by extending the electrical connection between the post 40 and the coupling element 30. Because the biasing member 70 may not be metallic and/or conductive, it may resist degradation, rust, corrosion, etc., to environmental elements when the connector 100 is exposed to such environmental elements. Furthermore, the resiliency of the biasing member 70 may deform under torque requirements, as opposed to permanently deforming in a manner similar to metallic or rigid components under similar torque requirements. Axial displacement of the connector body 50 may also occur, but the surface 49 of the post 40 may prevent axial displacement of the connector body 50, or friction fitting between the connector body 50 and the post 40 may prevent axial displacement of the connector body 50.

With continued reference to the drawings, FIG. 7 depicts an example of connector 101. Connector 101 may include post 40, coupling element 30, connector body 50, fastener member 60, biasing member 70, but may also include a mating edge conductive member 80 formed of a conductive material. Such materials may include, but are not limited to conductive polymers, conductive plastics, conductive elastomers, conductive elastomeric mixtures, composite materials having conductive properties, soft metals, conductive rubber, and/or the like and/or any operable combination thereof. The mating edge conductive member 80 may comprise a substantially circinate torus or toroid structure, and may be disposed within the internal portion of coupling element 30 such that the mating edge conductive member 80 may make contact with and/or reside continuous with a mating edge 46 of a post 40 connector 101 is operably configured (e.g. assembled for communication with interface port 20). For example, one example of the mating edge conductive member 80 may be an O-ring. The mating edge conductive member 80 may facilitate an annular seal between the coupling element 30 and post 40 thereby providing a physical barrier to unwanted ingress of moisture and/or other environmental contaminates. Moreover, the mating edge conductive member 80 may facilitate electrical coupling of the post 40 and coupling element 30 by extending therebetween an unbroken electrical circuit. In addition, the mating edge conductive member 80 may facilitate grounding of the connector 100, and attached coaxial cable (shown in FIG. 2), by extending the electrical connection between the post 40 and the coupling element 30. Furthermore, the mating edge conductive member 80 may effectuate a buffer preventing ingress of electromagnetic noise between the coupling element 30 and the post 40. The mating edge conductive member or O-ring 80 may be provided to users in an assembled position proximate the second end 42 of post 40, or users may themselves insert the mating edge conductive O-ring 80 into position prior to installation on an interface port 20. Those skilled in the art would appreciate that the mating edge conductive member 80 may be fabricated by extruding, coating, molding, injecting, cutting, turning, elastomeric batch processing, vulcanizing, mixing, stamping, casting, and/or the like and/or any combination thereof in order to provide efficient production of the component.

Referring now to FIGs. 8A and 8B, an embodiment of connector 200 according to the present invention is described. Embodiments of connector 200 include a post 40, a coupling element 30, a fastener member 60, a connector body 250 having biasing element 255, and a connector body member 90. Embodiments of the post 40, coupling element 30, and fastener member 60 described in association with connector 200 may share the same structural and functional aspects as described above in association with connectors 100, 101. Embodiments of connector 200 also include a post 40 having a first end 41, a second end 42, and a flange 45 proximate the second end 42, wherein the post 40 is configured to receive a center conductor surrounded 18 by a dielectric 16 of a coaxial cable 10, a coupling element 30 attached to the post 40, the coupling element 30 having a first end 31 and a second end 32, and a connector body 250 having biasing element 255, wherein the engagement biasing element 255 biases the coupling element 30 against the post 40.

With reference now to FIG. 9, and continued reference to FIGs. 8A and 8B, embodiments of connector 200 include a connector body 250 having a biasing element 255. The connector body 250 includes a first end 251, a second end 252, an inner surface 253, and an outer surface 254. Moreover, the connector body 250 includes a post mounting portion 257 proximate or otherwise near the second end 252 of the body 250; the post mounting portion 257 configured to securely locate the body 250 relative to a portion of the outer surface 44 of post 40, so that the connector body 250 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 200. In addition, the connector body 250 may include an extended, resilient outer annular recess 256 located proximate or near the second end 252 of the connector body 250. The extended, resilient annular recess 256 may extend a radial distance with respect to a general axis 5 of the connector 200 to facilitate biasing engagement with the coupling element 30. For instance, the extended annular recess 256 may radially extend past the internal wall 39 of the coupling element 30. In one embodiment, the extended, resilient annular recess 256 may be a resilient extension of annular recess 56 of connector body 50. In other embodiments, the extended, resilient annular recess 256, or shoulder, may function as a biasing element 255 proximate the second end 252. The biasing element 255 is structurally integral with the connector body 250, such that the biasing element 255 is a portion of the connector body 250. Moreover, the biasing element 255 of connector body 250 is defined as a portion of the connector body 255, proximate the second end 252, that extends radially and potentially axially (slightly) from the body to bias the coupling element 30, proximate the first end 31, into contact with the post 40. The biasing element 255 includes an annular groove 258 to permit the necessary deflection to provide a biasing force to effectuate constant physical contact between the lip 36 of the coupling element 30 and the outer tapered surface 47 of the flange 45 of the post 40. The annular groove 258 may be a notch, groove, channel, or similar annular void that results in an annular portion of the connector body 50 that is removed to permit deflection in an axial direction with respect to the general axis 5 of connector 200.

Accordingly, the biasing element 255 engages the coupling element 30 to bias the coupling element 30 into contact with the post 40. Contact between the coupling element 30 and the post 40 may promote continuity through the connector 200, reduce/eliminate RF leakage, and ensure a stable ground through the connection of the connector 200 to an interface port 20 in the event the connector 200 is not fully tightened onto the port 20. In most embodiments, the extended annular recess 256 or the biasing element 255 of the connector body 250 may provide a constant biasing force behind the coupling element 30. The biasing force provided by the extended annular recess 256, or biasing element 255, behind the coupling element 30 may result in constant contact between the lip 36 of the coupling element 30 and the outward tapered surface 47 of the post 40. However, the biasing force of the extending annular recess 256, or biasing element 255, should not (significantly) hinder or prevent the rotational movement of the coupling element 30 (i.e. rotation of the coupling element 30 about the post 40). Because connector 200 may include connector body 250 having an extended, resilient annular recess 256 to improve continuity, there may be no need for an additional component such as a metallic conductive continuity member that is subject to corrosion and permanent deformation during operable advancement and disengagement with an interface port 20, which may ultimately adversely affect the signal quality (e.g. corrosion or deformation of conductive member may degrade the signal quality)

Furthermore, the connector body 250 may include a semi-rigid, yet compliant outer surface 254, wherein the outer surface 254 may be configured to form an annular seal when the first end 251 is deformably compressed against a received coaxial cable 10 by operation of a fastener member 60. Further still, the connector body 250 may include internal surface features 259, such as annular serrations formed near or proximate the internal surface of the first end 251 of the connector body 250 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 250 may be formed of materials such as plastics, polymers, bendable metals or composite materials that facilitate a semi-rigid, yet compliant outer surface 254. Further, the connector body 250 may be formed of conductive or non-conductive materials or a combination thereof. Manufacture of the connector body 250 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.

Further embodiments of connector 200 may include a connector body member 90 formed of a conductive or non-conductive material. Such materials may include, but are not limited to conductive polymers, plastics, elastomeric mixtures, composite materials having conductive properties, soft metals, conductive rubber, rubber, and/or the like and/or any workable combination thereof. The connector body member 90 may comprise a substantially circinate torus or toroid structure, or other ring-like structure. For example, an embodiment of the connector body member 90 may be an O-ring disposed proximate the second end 254 of connector body 250 and the cavity 38 extending axially from the edge of first end 31 and partially defined and bounded by an outer internal wall 39 of coupling element 30 (see FIG. 4) such that the connector body O-ring 90 may make contact with and/or reside contiguous with the extended annular recess 256 of connector body 250 and outer internal wall 39 of coupling element 30 when operably attached to post 40 of connector 200. The connector body member 90 may facilitate an annular seal between the coupling element 30 and connector body 250 thereby providing a physical barrier to unwanted ingress of moisture and/or other environmental elements. Moreover, the connector body member 90 may facilitate further electrical coupling of the connector body 250 and coupling element 30 by extending therebetween an unbroken electrical circuit if connector body member 90 is conductive (i.e. formed of conductive materials). In addition, the connector body member 90 may further facilitate grounding of the connector 200, and attached coaxial cable 10 by extending the electrical connection between the connector body 250 and the coupling element 30. Furthermore, the connector body member 90 may effectuate a buffer preventing ingress of electromagnetic noise between the coupling element 30 and the connector body 250. It should be recognized by those skilled in the relevant art that the connector body member 90 may be manufactured by extruding, coating, molding, injecting, cutting, turning, elastomeric batch processing, vulcanizing, mixing, stamping, casting, and/or the like and/or any combination thereof in order to provide efficient production of the component.
