Description
Technical Field
The present disclosure relates generally to connectors for terminating coaxial cables. More particularly, the present disclosure relates to coaxial cable connectors having a torque limiting compression ring that does not require a mounted compression tool and breaks from the coupler body to function as a torque member.
Background
It has long been known to terminate coaxial cables with connectors to connect the cables to various electronic devices, such as televisions, radios, and the like. Conventional coaxial cables typically include a center conductor surrounded by an insulator. A braid or foil conductive shield is disposed over the conductor. An outer insulating sheath surrounds the shroud. To prepare the terminating coaxial cable, the outer jacket is stripped away, exposing a range of conductive shields folded back over the jacket. A portion of the insulator extends outwardly from the jacket and a range of center conductors extend outwardly from the insulator. Such prepared cables may be terminated in conventional coaxial connectors.
This type of coaxial connector includes a connector body having an inner cylindrical column interposed between an insulator and a conductive shield. A compression ring is provided for securing the cable within the body of the coaxial connector. A compression ring, typically made of resilient plastic, may be secured to the connector body to secure the coaxial connector to the connector body. Conventional connectors of this type require a compression tool for installation. Thus, the installer needs to carry these compression tools to the site; and if the compression tool breaks or misaligns, the conventional connector may not be assembled to the coaxial cable.
Further, some conventional compression tools may not be configured to ensure that the compression ring provides a desired amount of compression force to the coaxial cable. For example, the use of such conventional compression tools can result in the connector being assembled to the coaxial cable with insufficient compression force, resulting in signal attenuation or loss; this insufficient compressive force may cause the connector to become loose from the cable. On the other hand, the use of such conventional compression tools can result in the connector being assembled to the coaxial cable with too much compression force, resulting in signal attenuation or loss; this too high compressive force can damage the cable.
Accordingly, it would be desirable to provide a coaxial connector that can be assembled to a coaxial cable without the use of compression tools. In addition, it would be desirable to provide a coaxial connector that is assembled to a coaxial cable with a desired amount of compressive force. It would also be desirable to provide a coaxial connector that includes a broken ring that can be used to apply torque to the connector when securing the connector to the interface port.

Detailed Description
In the context of 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.
Fig. 1-6 illustrate an exemplary coaxial cable connector 10 in accordance with various aspects of the present disclosure. The connector 10 includes a body 12, a torque limiting compression ring 14, a coupler 18 (such as a ring nut), and an outer conductor coupling or ring post 20. The body 12 is an elongated, generally cylindrical conductive member, which may be made of, for example, metal, such as, but not limited to, brass. The body 12 includes a rearward portion 16 for receiving a coaxial cable and a forward portion 15 for coupling with a post 20.
The post 20 couples the forward portion 15 of the body 12 with the coupler 18 such that the coupler 18 is rotationally coupled to the body 12 and the post 20 to provide mechanical attachment of the connector 10 to an interface port of an external device. For example, the post 20 may include a rearward facing shoulder 21, the rearward facing shoulder 21 cooperating with a forward facing shoulder 19 of the coupler 18 to provide a rotatable coupling. An elastomeric sealing O-ring 22 may be located at its rotatable junction between the body 12 and the coupler 20 to provide a seal therebetween. A sealing gasket 77 may be provided at the forward end of the post 20 to provide a weather-tight seal between the coupler 18, the post 20, and the interface port.
The rearward portion 16 of the body 12 includes a cable receiving end 24 for insertably receiving an inserted coaxial cable. The coupler 18 includes an internally threaded end 26, the internally threaded end 26 allowing for screw threaded attachment of the connector 10 to an interface port of an external device. The cable receiving end 24 is at the rearward end of the rearward portion 16 of the body 12 and the internally threaded end 26 is at the forward end of the coupler 18.
The post 20 includes a base portion 28, the base portion 28 providing securement of the coupler 18 between the body 12 and the post 20 and an annular tubular extension 30, the annular tubular extension 30 extending rearwardly from the base portion 28 to the body 12. Additionally, the inner surface 40 of the forward portion 15 of the body 12 may include a retaining structure 42 (e.g., a radially inward projection), the retaining structure 42 mechanically coupled to a retaining structure 52, such as a recess of the outer surface 50 of the annular tubular extension 30 of the post 20. The retaining structures 42,52 may extend around the entire circumference or a portion of the circumference of the body and tubular extension, respectively. It should be appreciated that in some embodiments, the structures 42,52 may be reversed such that the retaining structure 42 is a recess and the retaining structure 52 is a protrusion. As will be described in further detail below and as is conventionally known, the extension 30 of the main body 20 and the rearward portion 16 of the main body 12 oppose the annular opening 32 for receiving the jacket and shield of an inserted coaxial cable.
The torque limiting compression ring 14 includes a generally cylindrical forward sleeve portion 33 and a rearward outer ring portion 35. The aft-facing outer ring portion 35 is attached to the forward sleeve portion 33 by a plurality of tabs or fingers 38, the tabs or fingers 38 tapering in a radially inward direction. The outer annulus portion 35 may include one or more torque assist features 88. The compression ring 14 is formed of a material selected such that when a desired torque is met during installation, the plurality of tabs 38 will shear, as described in more detail below. In some aspects, each of the tabs 38 may include a reinforcing member 39 at a radially outer portion 60 thereof. The tapering of the tabs 38 and the reinforcement member 39 facilitates fracture of the tabs 38 at a radially inner portion 62 of the tabs 38, the radially inner portion 62 being connected to the forward sleeve portion 33. In addition, the body 12 includes a first stop 17 at the rearward end of the rearward portion 16 and a second stop 19, the second stop 19 being formed by a shoulder extending radially inward from the inner surface 13 of the rearward portion 12. The first and second stops 17, 19 prevent over-tightening of the compression ring 14 to the body 12.
The forward sleeve portion 33 has a flared rearward end 34 through which a cable may be inserted and an opposite forward end 36 that may be inserted into the cable receiving end 24 of the body 12. The outer surface 64 of the forward end 36 of the compression ring 14 includes a threaded portion 66, the threaded portion 66 threadably coupled with a threaded portion 68 of the inner surface 13 of the rearward portion 16 of the body 12. The threaded portions 66,68 allow for a releasable, reattachable coupling of the compression ring 14 to the body 12. Further, as compression ring 14 rotates clockwise relative to body 12, compression ring 14 moves axially in the direction of arrow a of fig. 2 from a first position, shown in fig. 2 and 4, which loosely retains the coaxial cable within body 12, toward coupler 18 to a second, more forward position, shown in fig. 3, which secures the cable within body 12.
Since the components of the connector 10 have been described in detail, the use of the connector 10 to terminate a coaxial cable will now be described with respect to fig. 4. The coaxial cable 90 includes an elongated inner conductor 92 formed of copper or similar conductive material. A conductor insulator 94 formed of a suitable insulating plastic extends around the inner conductor 92. A metal shield 96 is positioned in surrounding relation around the insulator 94. In some aspects, the shield 96 is a metallic braid, however other conductive materials, such as a metallic foil, may also be employed. An outer insulating sheath 98 covers the shroud 96.
The cable 90 is prepared in a conventional manner for termination by stripping off the jacket 98 (thereby exposing a range of the shroud 96). A portion of the insulator 94 extends from the shield 96, with a range of conductors 92 extending from the insulator 92. The manufacturing process includes folding back a range of shields 96 around the sheath 98. As shown in the exploded view of fig. 4, a cable 90 may be inserted into the connector 10 with the compression ring 14 coupled to the body 12, as shown in fig. 2 and 4. In this technique, the prepared cable 90 is inserted through the outer annulus portion 35, through the rearward end 34 of the forward sleeve portion 33, and into the receiving end 24 of the body 12. The extension 30 of the post 20 is interposed between the insulators 94 of the metal shroud 96 such that the shroud 96 and the sheath 98 reside within the annular region 32 defined between the post 20 and the rearward portion 16 of the body 12. In this position, the compression ring 14 is coupled to the body in the first position shown in fig. 2 and 4. In such a first position, sufficient clearance between compression ring 14 and post 20 is provided so that extension 30 may be easily interposed between insulator 94 and shroud 96.
Once the cable 60 is properly inserted, the threaded portion 66 of the compression ring 14 is threadably coupled with the threaded portion 68 of the body 12, and the compression ring 14 is rotated clockwise relative to the body 12 such that the compression ring 14 moves axially in the direction of arrow a toward the coupler 18. As the radially inward projecting portion 80 of the forward sleeve portion 33 of the compression ring 14 moves axially over the barbed portion 82 at the rearward end of the extension 30 of the post 20, the forward sleeve portion 33 compresses the folded-back metal shield 96 and jacket 98 of the cable 90 against the extension 30 of the post 20. As a result of this compression, the torque required to continue to compress the rotation of ring 14 relative to body 12 increases. When the desired installation torque is reached, as another torque is applied to the outer annulus portion 35 of the compression annulus 14, the material of the tabs 38, the tapering of the tabs 38 and/or the reinforcing members 39 facilitate fracture of the tabs 38 at the radially inner portions 62 of the tabs 38, the radially inner portions 62 being connected to the forward sleeve portion 33. Another torque will cause the tabs 38 to shear, causing the outer annulus portion 35 to separate from the forward sleeve portion 33. The outer ring portion 35 may then be moved back along the cable 90 in a direction away from the coupler 18 (opposite arrow a). At this point, the installer may couple a fastening tool to the connector 10 to fasten the coupler 18 to the interface port.
Fig. 8-11 illustrate another exemplary coaxial cable connector 10 according to various aspects of the present disclosure. The connector 110 includes a body 12, a torque limiting compression ring 114, a coupler 18 (such as a ring nut), and an outer conductor coupling or ring post 20.
The torque limiting compression ring 114 includes a generally cylindrical forward sleeve portion 133 and a rearward outer ring portion 135. The aft-outward ring portion 135 is attached to the forward sleeve portion 133 by a plurality of tabs or fingers 138, the tabs or fingers 38 tapering in a radially outward direction (i.e., opposite to that shown in fig. 2). The outer annulus portion 135 may include one or more torque assist features 188. The compression ring 114 is formed of a material selected such that when a desired torque is met during installation, the plurality of tabs 138 will shear as described above in connection with the embodiments shown in fig. 1-7. The tapering of the tabs 138 facilitates breaking of the tabs 138 at a radially outer portion 162 of the tabs 138, the radially outer portion 62 being connected to the forward sleeve portion 133.
The outer surface 164 of the forward end 136 of the compression ring 114 includes a threaded portion 166, the threaded portion 66 threadably coupled with the threaded portion 68 of the inner surface 13 of the rearward portion 16 of the body 12. The threaded portion 166,68 allows for a releasable, reattachable connection of the compression ring 114 to the body 12. Further, as compression ring 114 rotates clockwise relative to body 12, compression ring 114 is axially movable along arrow a of fig. 2 and 8 from a first position, shown in fig. 2 and 8, which loosely retains the coaxial cable within body 12, toward coupler 18 to a second, more forward position, shown in fig. 3, which secures the cable within body 12.
Referring to fig. 9 and 11, the outer ring portion 135 and tabs of the compression ring 114 may be constructed and arranged such that when the tabs shear to separate the outer ring portion 135 from the forward sleeve portion 133, the resulting inner opening 170 is sized to fit over the connector body 12 and the coupler 18, and the compression ring 114 may be moved about the coupler 18 in the direction a to a certain position. For example, the inner surface 172 of the sheared outer annulus portion 135 may have a hexagonal shape that complements the shape of the coupling 18, and the inner opening 170 is sized relative to the coupling 18 such that the outer annulus portion 135 may act as a torque assist member to secure the coupling 18 to the interface port.
As described above, in some aspects, the connectors 10,110 of the present disclosure may be configured to be supplied in an assembled state as shown in fig. 1, 3, and 8. In such an assembled state and as will be described in further detail below, coaxial cables may be inserted through the rearward ends 34,134 of the forward sleeve portions 33,133 of the compression rings 14,114 and into the body 12. The compression rings 14,114 are movable from a first position to a second position, thereby locking the cable to the body 12; the first position loosely holds the cable and the second position is axially forward. However, it is contemplated that in some aspects, the compression rings 14,114 may be disengaged from the body 12 and placed around the coaxial cable to allow the coaxial cable to be directly inserted into the cable receiving end 24 of the body 12. Thereafter, the compression rings 14,114, which have been placed around the cable, may be reattached to the cable receiving end 24 of the body 12, wherein the cable receiving end 24 may be moved from the first position to the second position, which locks the cable to the connector body. The threaded portion 66,168,68 described above is used to provide such disengagement and reattachment of the compression rings 14,114 to the body 12. In other embodiments, the connectors 10,110 may be supplied in an unassembled state (not shown) in which the compression rings 14,114 are separated from the body 12.
Additional embodiments include any of the embodiments described above, wherein one or more of its components, functions, or structures are interchanged with, substituted, or augmented by, one or more of the components, functions, or structures of the different embodiments described above.
It should be understood that various changes and modifications to the embodiments described herein will be apparent to those skilled in the art. Such changes and modifications can be made without departing from the spirit and scope of the present disclosure and without diminishing its intended advantages. Accordingly, such changes and modifications are contemplated by the appended claims.
Although some embodiments of the present disclosure have been described in the foregoing specification, those skilled in the art will appreciate that many modifications and other embodiments of the present disclosure will come to mind to which the disclosure pertains, having the benefit of the teachings presented in the foregoing descriptions and the associated drawings. Therefore, it is to be understood that the disclosure is not to be limited to the specific embodiments disclosed and that modifications and other embodiments are intended to be included within the scope of the appended claims. Furthermore, although specific terms are used herein and in the claims that follow, such terms are used in a generic and descriptive sense only and not for the purposes of limiting the disclosure or the claims that follow.
