DETAILED DESCRIPTION
Embodiments disclosed herein coaxial cable connectors used to connect a coaxial cable to an equipment port or terminal such that secure mechanical and electrical connections result. The terms “equipment port” and “terminal” may be used interchangeably herein. It should be understood that each of these terms shall mean or refer to any device or structure to which the coaxial cable connector attaches to mechanically and/or electrically connect a coaxial cable thereto. The coaxial cable connector includes attachment feature for attaching the coaxial cable connector to the equipment port or terminal. The attachment feature may be any suitable attachment device, including, without limitation, rotatable coupler, also referred to as a nut, or push-on component. A body is secured to the coupler at one end in a manner so that it does not rotate with coupler. A post is secured to and inside of the body. A shell is movably attached to the body at another end such that shell can axially move toward coupler. A gripping member is frictionally fit inside of shell. The shell accepts the coaxial cable which is inserted through shell and the gripping member and is secured to an end of post so that coaxial cable positions between post and body inside of body. The gripping member is configured to secure coaxial cable to coaxial cable connector. In this regard, when an axially compressive force is applied to shell to move shell axially toward coupler, the gripping member also moves and at least a part of gripping member is forced between body and coaxial cable.
The gripping member has a front end and a rear end opposite the front end, and an outer surface and an inner surface defining a longitudinal hole extending between the front end and the rear end. A first portion of the gripping member terminates at the front end. A second portion of the gripping member terminates at the rear end. The gripping member is configured to secure the coaxial cable to the coaxial cable connector. The gripping member secures the coaxial cable to the coaxial cable connector when at least part of the gripping member is forced under the body. The gripping member may be forced under body of a coaxial cable connector when driven axially forward by the shell to secure coaxial cable to the connector. When forced under the body, the first portion or front end the gripping member may be displaced radially inwardly. The shell includes a structure to move the rear end/second portion of the gripping member radially outwardly upon compression. In some embodiments, the shell includes a structure to prevent a rear portion of the gripping member from moving radially inwardly upon compression. In various embodiments, the structure may comprise, for example, a machined component, a stamped component such as a one- or multi-piece stamped component, or another structure adapted to move a rear portion of the gripping member radially outwardly upon compression and/or prevent a rear portion of the gripping member from moving radially inwardly upon compression. Various embodiments of connectors and coaxial cable assemblies are described in detail below.
A coaxial cable has a center or inner conductor that is surrounded by a dielectric layer. The dielectric layer (or dielectric) may also have a foil or other metallic covering. The coaxial cable then has a braided outer conductor which is covered and protected by a jacket. Typically, to prepare the coaxial cable for attachment to a coaxial cable connector, a portion of the center conductor is exposed. The jacket is trimmed back so that a portion of the dielectric (and metallic covering) and braided outer conductor are exposed. The braided outer conductor is then folded back over the jacket, to expose the dielectric (and the metallic covering if present). Whenever possible, the same reference numerals will be used throughout the drawings to refer to the same or like parts
FIGS. 1 and 3 schematically depict a cross sectional view of an example embodiment of a coaxial cable connector 100 for coupling an end of a coaxial cable to a terminal. In this embodiment, the coaxial cable connector 100 includes a coupler 200 adapted to couple to the terminal. The coaxial cable connector 100 also includes a body 400 secured to the coupler 200 at one end in a manner so that the body 400 does not rotate with coupler 200. A post 300 is secured to and disposed inside of the body 400 and comprises a backstop 20 and a contacting portion 30 extending from a collar portion 31 of the post 300. As is clearly illustrated in FIGS. 1 and 3, the backstop 20, which is illustrated with the post 300 in cross section, is positioned to engage the contacting portion 30 mid-span, at a discrete point between the collar portion 31 of the post 300 and the end of the contacting portion 30 that is in contact with the inside bore of the coupler 200. As is clearly illustrated in FIG. 3, the backstop 20 defines a fulcrum at a discrete point between the collar portion 31 of the post 300 and the end of the contacting portion 30 in contact with the inside bore 22 of the coupler 200 about which the end of the contacting portion 30, in contact with the inside bore 22 of the coupler 200, may pivot. As will be appreciated by those familiar with the art, US 2014/0106612 A1 discloses coaxial cable connectors comprising posts with contacting portions in a variety of different configurations.
A shell 600 is movably attached to the body 400 at an opposite end such that the shell 600 can axially move toward coupler 200. A gripping member 500 is frictionally fit inside of the shell 600. The shell 600 accepts the coaxial cable which is inserted through shell 600 and the gripping member 500 and is secured to an end of the post 300 so that the coaxial cable positions between the post 300 and the body 400 inside of the body. The gripping member 500 is configured to secure the coaxial cable to the coaxial cable connector 100. In this regard, when an axially compressive force is applied to the shell 600 to move the shell 600 axially toward the coupler 200, the gripping member 500 also moves and at least a part of the gripping member 500 is forced between the body 400 and the coaxial cable.
In one embodiment, the coupler 200, the post 300, the body 400, and the shell 600 may be made from a conductive material such as nickel plated brass or the like. The gripping member 500 may be made from a non-conducting material, such as a plastic such as acetal. The gripping member 500 at least partially includes a front portion 501, a back portion 502, a rearward facing surface 503, an internal surface 504, and a reduced diameter portion 505. The shell 600 at least partially includes a front end 601, a back end 602 and a surface 603. The reduced diameter portion 505 creates an annular gap 506 between the gripping member 500 and the shell 600. The surface 603 of the shell 600 is configured to drive the rearward facing surface 503 and at least a portion of the internal surface 504 of the gripping member 500 radially outwardly when driven axially against the rearward facing surface 503 by means of a reverse rake angle of the surface 603 oriented in a direction angled from the rear end 602 of the shell 600 toward the front end 601 of the shell 600 as the surface 603 extends from an inner surface of the shell 600 into a longitudinal opening defined by the shell 600.
FIG. 2 schematically depicts a cross sectional view of an example embodiment of a gripping member 500 and a shell 600 of the coaxial cable connector 100 shown in FIG. 1 in an unassembled state. As described above with reference to FIG. 1, the gripping member 500 includes a front portion 501, a back portion 502, a rearward facing surface 503, an internal surface 504, and a reduced diameter portion 505. The shell 600 at least partially includes a front end 601, a back end 602 and a surface 603. The reduced diameter portion 505 of the gripping member 500 creates an annular gap 506 between the gripping member 500 and the shell 600. The surface 603 of the shell 600 is configured to drive the rearward facing surface 503 and at least a portion of the internal surface 504 of the gripping member 500 radially outwardly when driven axially against the rearward facing surface 503 by means of a reverse rake angle of the surface 603 oriented in a direction angled from the rear end 602 of the shell 600 toward the front end 601 of the shell 600 as the surface 603 extends from an inner surface of the shell 600 into a longitudinal opening defined by the shell 600. Thus, in this embodiment, a distal end of the forward angled surface extends into the longitudinal opening of the shell and is disposed forward (i.e., closer to the front end 601) relative to a proximal end of the forward facing surface disposed at or near (e.g., at least generally adjacent to) the inner surface of the shell 600.
FIG. 3 schematically depicts the example embodiment of the coaxial cable connector 100 shown in FIG. 1 with a coaxial cable 1000 inserted into the coaxial cable connector 100. In FIG. 3, the coaxial cable connector 100 is in a closed condition in which the shell 600 has been axially moved in a forward direction over the body 400 toward the coupler 200 of the connector 100. The front portion 501 of the gripping member 500 has been forced cylindrically into or under the body 400 and has been deformed radially inwardly towards the coaxial cable 1000. In one embodiment, for example, the front portion 501 of the gripping member contacts an outer jacket of the coaxial cable 1000 as shown in FIG. 3 and further environmentally seals the junction of the coaxial cable connector 100 and the coaxial cable 1000.
At least a portion of the rear portion 502, a portion of the internal surface 504, and a portion of the rearward facing surface 503 of the gripping member 500 have been forced at least partially radially outwardly by the angled surface 603 of the shell 600 as evidenced by a volumetric reduction in an annular gap 506 and by the general shape of the resulting component configuration.
FIG. 4 schematically depicts a cross section of another example embodiment of a gripping member 500′ of a coaxial cable connector according to one or more embodiments. In the particular implementation shown in FIG. 4, for example, a rearward facing surface 503′ of the gripping member 500′ includes a reverse rake angle corresponding to the surface 603 of the shell 600 described above with respect to FIGS. 1 and 2. Thus, in the embodiment shown in FIG. 5, the rearward facing surface 503′ is angled in a direction extending from the rear end 502 of the gripping member 500 toward the front portion 501 of the gripping member 500 as the surface extends from an inner surface of the gripping member 500 into a longitudinal opening of the gripping member 500.

The shell 610 at least partially includes an angled surface 611 and a recess 612, such as formed by an annular channel in the shell 610. The recess 612 of the shell provides an annular gap 513 around the gripping member in this first uncompressed position.
FIG. 6 schematically depicts a cross section of the example embodiment of the gripping member 510 and the shell 610 shown in FIG. 5 as a sub-assembly in a second compressed position. In this embodiment, the shell 610 has been forced in an axially forward direction toward the gripping member 510 as it would be during compression of a coaxial cable connector. In this embodiment, at least a portion of the outer ring 511 and a portion of the inner area 512 of the gripping member 510 have been forced at least partially radially outwardly by the angled surface 611 of the shell 610 as evidenced by a volumetric reduction in annular gap 513, an increase in volumetric space around inner area 512, and by the general shape of the resulting component configuration.
FIG. 7 schematically depicts a cross section of an example embodiment of a gripping member 520 and a shell 620 as a sub-assembly in a first uncompressed position. In this embodiment, the gripping member 520 at least partially comprises a reduced diameter portion 521 and an inner area 522. The shell 620 at least partially includes an angled surface 621 and a bore 622. The reduced diameter portion 521 of the gripping member 520 creates annular gap 523 between the gripping member 520 and the bore 622 of the shell 620.
FIG. 8 schematically depicts a cross section of an example embodiment of a gripping member 520 and a shell 620 as a sub-assembly in a second compressed position. In this embodiment, the shell 620 has been forced in an axially forward direction toward the gripping member 520 as it would be during compression of a coaxial cable connector. As such, at least a portion of the reduced diameter portion 521 and a portion of the inner area 522 of the gripping member 520 have been forced at least partially radially outwardly by the angled surface 621 of the shell 620 as evidenced by a volumetric reduction in the annular gap 523, an increase in volumetric space around the inner area 522, and by the general shape of the resulting component configuration.
FIG. 9 schematically depicts a cross section of another example embodiment of a gripping member 530 and a shell 630 as a sub-assembly in a first uncompressed position. In this embodiment, the gripping member 530 at least partially comprises a reduced diameter portion 531 and an inner area 532. The shell 630 at least partially includes an angled surface 631 and a bore 632. The reduced diameter portion 531 of the gripping member 530 creates annular gap 533 between the gripping member 530 and the bore 632 of the shell 630. Additionally, in this implementation, the shell 630 may be produced by a stamping or deep draw operation that is more economical to produce than a shell made by machining or turning operations.
FIG. 10 schematically depicts a cross section of the example embodiment of the gripping member 530 and the shell 630 shown in FIG. 9 as a sub-assembly in a second compressed position. In this embodiment, the shell 630 has been forced in an axially forward direction toward the gripping member 530 as it would be during compression of a coaxial cable connector. As such, at least a portion of the reduced diameter portion 531 and a portion of the inner area 532 of the gripping member 520 have been forced at least partially radially outwardly by the angled surface 631 of the shell 630 as evidenced by a volumetric reduction in the annular gap 533, an increase in volumetric space around the inner area 532, and by the general shape of the resulting component configuration.

In this embodiment, the gripping member 540 at least partially includes an outer diameter 541 and an inner area 542. The shell 640 at least partially includes a structure 641 such as a curved forward facing surface and a bore 642. Additionally, in this implementation, the shell 640 may be produced by a stamping or deep draw operation that is more economical to produce than a shell made by machining or turning operations.
FIG. 12 schematically depicts a cross section of the gripping member 540 and the shell 640 as a sub-assembly in which a forming tool 2000 has been introduced to complete the sub-assembly by forming the structure 641 (e.g., the curved forward facing surface) of the shell 600 radially outwardly. The forming operation captures the gripping member 540 within the shell 640 and creates an annular barrier to prevent the inner area 542 of the gripping member 540 from moving radially inwardly.
FIG. 13 schematically depicts a cross-section of the gripping member 540 and the shell 640 as sub-assembly in a final assembled condition with the forming tool 2000 removed.
