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.
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.

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.

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 a shoulder surface 58a forming part of 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 may 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.
Embodiments 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 embodiment 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, embodiments of the biasing member 70 may be an O-ring configured to cooperate with the shoulder surface 58a forming part of 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 shoulder surface 58a forming part of 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 shoulder surface 58a, or proximate surfaces, forming the annular recess 56 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 can 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

Accordingly, a portion of the extended, resilient annular recess 256, or the biasing member 255, may engage 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 member 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 member 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 member 255, may 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

Embodiments of connector 300 may include a connector body 350 having a biasing member 355. The connector body 350 may include a first end 351, a second end 352, an inner surface 353, and an outer surface 354. Moreover, the connector body 350 may include a post mounting portion 357 proximate or otherwise near the second end 352 of the body 350; the post mounting portion 357 configured to securely locate the body 350 relative to a portion of the outer surface of post 340, so that the connector body 350 is axially secured with respect to the post 340, 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 300. In addition, the connector body 350 may include a biasing member 355. Embodiments of the biasing member 355 may be a resilient, extended portion of the connector body 350 proximate or near the second end 352 of the connector body 350. Other embodiments of the biasing member 355 may be one or more resilient fingers arcuately extending from the second end 352 of the connector body 350; the one or more resilient fingers may be separated by one or openings 359, wherein the openings 359 may be slits, slots, openings, grooves, voids, and the like. The resilient, extended portion(s) of the connector body 350 forming the biasing member 355 may extend a radial distance with respect to a general, central axis 5 of the connector 300 to facilitate biasing engagement with the coupling element 330. For instance, the biasing member 355 may extend past the wall 39 of the coupling element 330. In addition, embodiments of the biasing member 355 may be structurally integral with the connector body 350, such that the biasing member 355 is a portion of the connector body 350. In other embodiments, the biasing member 355 may be a separate component fitted or configured to be coupled with (e.g. adhered, snapped on, interference fit, and the like) an existing connector body, such as connector body 350. Moreover, the biasing member 355 of connector body 350 may be defined as a portion of the connector body 355, proximate the second end 352, that extends radially and potentially axially from the body to bias the coupling element 330, proximate the first end 331, into contact with the post 340. The biasing member 355 may include a notch 358 to permit the necessary deflection of the biasing member 355 to provide a biasing force to effectuate constant physical contact between the lip 336 of the coupling element 330 and the outer tapered surface 347 of the flange 345 of the post 340. The notch 358 may be a notch, groove, channel, or similar annular void that results in an annular or semi-annular portion of the connector body 350 that is removed to permit deflection in an axial direction with respect to the general axis 5 of connector 300.
Accordingly, an extended portion of the connector body 350, such as the biasing member 355, may engage the coupling element 330 to bias the coupling element 330 into contact with the post 340. Contact between the coupling element 330 and the post 340 may promote continuity through the connector 300, reduce/eliminate RF leakage and/or interference, and ensure a stable ground through the connection of the connector 300 to an interface port regardless if the connector 300 is fully tightened onto the port. In most embodiments, the biasing member 355 of the connector body 350 may provide a constant biasing force behind the coupling element 330. The biasing force provided by the biasing member 355, behind the coupling element 330 may result in constant contact between the lip 336 of the coupling element 330 and the outward tapered surface 347 of the post 340. However, the biasing force of the biasing member 355, may not (significantly) hinder or prevent the rotational movement of the coupling element 330 (i.e. rotation of the coupling element 330 about the post 340). Because connector 300 may include a connector body 350 having an extended, resilient portion 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 350 may include a semi-rigid, yet compliant outer surface 354, wherein the outer surface 354 may be configured to form an annular seal when the first end 351 is deformably compressed against a received coaxial cable 10 by operation of a fastener member 360. Further still, the connector body 350 may include internal surface features, such as annular serrations formed near or proximate the internal surface of the first end 351 of the connector body 350 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 350 may be formed of materials such as plastics, polymers, bendable metals or composite materials that facilitate a semi-rigid, yet compliant outer surface 354. Further, the connector body 350 may be formed of conductive or non-conductive materials or a combination thereof. Manufacture of the connector body 350 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 400 may include a connector body 450 having a biasing member 455. The connector body 450 may include a first end 451, a second end 452, an inner surface 453, and an outer surface 454. Moreover, the connector body 450 may include a post mounting portion 457 proximate or otherwise near the second end 452 of the body 450; the post mounting portion 457 configured to securely locate the body 450 relative to a portion of the outer surface of post 440, so that the connector body 450 is axially secured with respect to the post 440, 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 400.

The resilient, extended portion(s) of the connector body 450 forming the biasing member 455 may extend a radial distance with respect to a general, central axis 5 of the connector 400 to facilitate biasing engagement with the coupling element 430. For instance, the biasing member 455 may extend past the wall 439 of the coupling element 430. In addition, embodiments of the biasing member 455 may be structurally integral with the connector body 450, such that the biasing member 455 is a portion of the connector body 450. In other embodiments, the biasing member 455 may be a separate component fitted or configured to be coupled with (e.g. adhered, snapped on, interference fit, and the like) an existing connector body, such as connector body 450.

The biasing member 455 may include a notch 458 to permit the necessary deflection of the biasing member 455 to provide a biasing force to effectuate constant physical contact between the lip 436 of the coupling element 430 and the outer tapered surface 447 of the flange 445 of the post 440. The notch 458 may be a notch, groove, channel, or similar annular void that results in an annular or semi-annular portion of the connector body 450 that is removed to permit deflection in an axial direction with respect to the general axis 5 of connector 400.
Accordingly, an extended portion of the connector body 450, such as the biasing member 455, may engage the coupling element 430 to bias the coupling element 430 into contact with the post 440. Contact between the coupling element 430 and the post 440 may promote continuity through the connector 400, reduce/eliminate RF leakage and/or interference, and ensure a stable ground through the connection of the connector 400 to an interface port regardless if the connector 400 is fully tightened onto the port. In most embodiments, the biasing member 455 of the connector body 450 may provide a constant biasing force behind the coupling element 430. The biasing force provided by the biasing member 455, behind the coupling element 430 may result in constant contact between the lip 436 of the coupling element 430 and the outward tapered surface 447 of the post 440. However, the biasing force of the biasing member 455, may not (significantly) hinder or prevent the rotational movement of the coupling element 430 (i.e. rotation of the coupling element 430 about the post 440). Because connector 400 may include a connector body 450 having an extended, resilient portion 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, which may ultimately adversely affect the signal quality (e.g. corrosion or deformation of conductive member may degrade the signal quality).

Moreover, embodiments of a coaxial cable connector 500 can include a biasing member 570. The biasing member 570 may be formed of a non-metallic material to avoid rust, corrosion, deterioration, and the like, caused by environmental elements, such as water and moisture. Additional materials the biasing member 570 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 570 may be a resilient, rigid, semi-rigid, flexible, or elastic member, component, element, and the like. The resilient nature of the biasing member 570 may help avoid permanent deformation while under the torque requirements when a connector 500 is advanced onto an interface port 20.
Moreover, the biasing member 570 may facilitate constant contact between the coupling element 530 and the post 540. For instance, the biasing member 570 may bias, provide, force, ensure, deliver, etc. the contact between the coupling element 530 and the post 540. The constant contact between the coupling element 530 and the post 540 promotes continuity through the connector 500, reduces/eliminates RF leakage and/or interference, and ensures a stable ground through the connection of a connector 500 to an interface port 20 in the event the connector 500 is not fully tightened onto the port 20. To establish and maintain solid, constant contact between the coupling element 530 and the post 540, the biasing member 570 may be disposed behind the coupling element 530, proximate or otherwise near the second end 552 of the connector body 550. In other words, the biasing member 570 may be disposed within the cavity 538 formed between the coupling element 530 and the annular recess 556 of the connector body 550. The biasing member 570 can provide a biasing force against the coupling element 530, which may axially displace the coupling element 530 into constant direct contact with the post 540. In particular, the disposition of a biasing member 570 in annular cavity 538 proximate the second end 552 of the connector body 550 may axially displace the coupling element 530 towards the post 540, wherein the lip 536 of the coupling element 530 directly contacts the outer tapered surface 547 of the flange 545 of the post 540. The location and structure of the biasing member 570 may promote continuity between the post 540 and the coupling element 530, but may not impede the rotational movement of the coupling element 530 (e.g. rotational movement about the post 540). The biasing member 570 may also create a barrier against environmental elements, thereby preventing environmental elements from entering the connector 500. Those skilled in the art would appreciate that the biasing member 570 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.
Embodiments of biasing member 570 may include an annular or semi-annular resilient member or component configured to physically and electrically couple the post 540 and the coupling element 530. One embodiment of the biasing member 570 may be a substantially rectangular cross-sectioned collar, or other ring-like structure having a cross-sectional area large enough that when disposed within annular cavity 538 proximate the annular recess 556 of the connector body 550, the coupling element 530 is axially displaced against the post 540 and/or biased against the post 540. Moreover, embodiments of the biasing member 570 may be resilient collar member configured to cooperate with the annular recess 556 proximate the second end 552 of connector body 550 and the outer internal wall 539 and lip 536 forming cavity 538 such that the biasing member 570 may make contact with and/or bias against a shoulder surface 558 forming a part of the annular recess 556 of connector body 550 and outer internal wall 539 and lip 536 of coupling element 530. The biasing between the outer internal wall 539 and lip 356 of the coupling element 530 and the shoulder surface 558 forming part of the annular recess 556, and surrounding portions, of the connector body 550 can drive and/or bias the coupling element 530 in a substantially axial or axial direction towards the second end 2 of the connector 500 to make solid and constant contact with the post 540. For instance, the biasing member 570 can be sized and dimensioned large enough (e.g. oversized collar) such that when disposed in cavity 538, the biasing member 570 exerts enough force against both the coupling element 530 and the connector body 550 to axial displace the coupling element 530 a distance towards the post 540. Thus, the biasing member 570 may facilitate grounding of the connector 500, and attached coaxial cable 10 (shown in
