In embodiments, the coupler 110 defines a thread 118 at the front portion 114 of the coupler 110. The thread 118, in embodiments, is structurally configured to engage a corresponding thread of a port of a device, such as a television, a cable box, or the like to couple the coaxial cable connector assembly 100 to the port of the device. The coupler 110 may be formed of a material suitable to conduct electricity, such as copper, brass, aluminum, or the like, and in embodiments, the coupler 110 is electrically coupled to the outer conductor 16 of the coaxial cable 10, as described in greater detail herein.
(21) In some embodiments, the coaxial cable connector assembly 100 includes an outer conductor engagement feature 124 that extends inwardly from the inner channel 112 of the coupler 110. The outer conductor engagement feature 124 is structurally configured to contact the outer conductor 16 of the coaxial cable 10 when the coaxial cable 10 is positioned at least partially within the coupler 110. Through contact with the outer conductor 16, the outer conductor engagement feature 124 may electrically couple the thread 118 of the coupler 110 to the outer conductor 16 of the coaxial cable 10. By electrically coupling the thread 118 of the coupler 110 to the outer conductor 16 of the coaxial cable 10, the coaxial cable connector assembly 100 may facilitate electrical connection between the outer conductor 16 of the coaxial cable 10 and the port of a device, even when the coupler 110 is not fully seated on the port of the device.
(22) In the embodiment depicted in
(23) In some embodiments, the coaxial cable connector assembly 100 includes a retainer 130 engaged with the coupler 110 and the rear body 160. In these embodiments, the retainer 130 generally couples the coupler 110 to the rear body 160. For example, in embodiments, the retainer 130 includes a flange 132 that extends outwardly from a tubular portion 134 of the retainer 130. In embodiments, the flange 132 of the retainer 130 may be engaged with the rear body 160, and the tubular portion 134 may be coupled to the coupler 110, such that the coupler 110 is rotatably coupled to the rear body 160 through the retainer 130. While in the embodiment depicted in
(24) In embodiments, the rear body 160 defines a cable channel 162 extending through the rear body 160. The cable channel 162 is structurally configured to receive the coaxial cable 10 as the coaxial cable 10 is inserted within the coaxial cable connector assembly 100.
(25) In some embodiments, the coaxial cable connector assembly 100 further includes a tubular post 150 positioned at least partially within the cable channel 162 of the rear body 160. In embodiments, the tubular post 150 may be inserted between the outer braid 18 of the coaxial cable 10 and the dielectric material 14 or between the outer braid 18 and the outer conductor 16 of the coaxial cable 10. In some embodiments, the tubular post 150 may make an electrical connection with the outer braid 18 and/or the outer conductor 16 of the coaxial cable 10.
(26) In embodiments, the coaxial cable connector assembly 100 includes an adhesive reservoir 180 positioned at least partially within the cable channel 162 of the rear body 160. In the embodiment depicted in
(27) The adhesive reservoir 180 generally includes an adhesive reservoir breakable material 182 that encapsulates an adhesive 184. Similarly, the hardener reservoir 190 includes a hardener reservoir breakable material 192 that encapsulates a hardener 194. In some embodiments, the hardener 194 includes a material that is structurally configured to react with the adhesive 184. For example in some embodiments, the adhesive 184 is initially in a fluid state, and upon reaction with the hardener 194 over a period of time, the adhesive 184 hardens to a solid state. The hardener 194 may include any suitable composition for reacting with the adhesive 184 to harden the adhesive 184, and may include, for example and without limitation, borax or the like. In embodiments, the adhesive reservoir breakable material 182 of the adhesive reservoir 180, and the hardener reservoir breakable material 192 of the hardener reservoir 190 may include any suitable rupturable, tearable, and/or frangible material structurally configured to break upon the application of a force exceeding a predetermined threshold.
(28) Referring to
(29) In some embodiments, the coaxial cable connector assembly 100 includes a plurality of reservoirs. For example and referring to
(30) Referring collectively to
(31) With the coaxial cable 10 in contact with the adhesive reservoir 180 and/or the hardener reservoir 190, further insertion of the coaxial cable 10 into the coaxial cable connector assembly 100 imparts a force on the adhesive reservoir 180 and/or the hardener reservoir 190. When the force exceeding a predetermined threshold is applied to the adhesive reservoir 180 and/or the hardener reservoir 190 (e.g., via the coaxial cable 10), the adhesive reservoir breakable material 182 of the adhesive reservoir 180 and/or the hardener reservoir breakable material 192 of the hardener reservoir 190 fractures, releasing the adhesive 184 from the adhesive reservoir 180 and releasing the hardener 194 from the hardener reservoir 190. In embodiments including one or more adhesive reservoirs 180 and one or more hardener reservoirs 190, the released adhesive 184 reacts with the released hardener 194 to solidify and couple the coaxial cable 10 to the coaxial cable connector assembly 100. In embodiments that only include one or more adhesive reservoirs 180, the released adhesive 184 may react with water (i.e., humidity in air) and/or the activator 170 positioned on the rear body 160 and/or the tubular post 150 to solidify and couple the coaxial cable 10 to the coaxial cable connector assembly 100.
(32) As the coaxial cable 10 is inserted into the coaxial cable connector assembly 100, the outer conductor 16 and/or the outer braid 18 contacts the outer conductor engagement feature 124. Contact between the outer conductor 16 and/or the outer braid 18 of the coaxial cable 10 and the outer conductor engagement feature 124, in embodiments, electrically couples the threads 118 of the coupler 110 to the outer conductor 16 and/or the outer braid 18. As noted above, the outer conductor 16 and/or the outer braid 18 may be maintained at ground potential, and may be connected to a port of a device. By electrically coupling the outer conductor 16 and/or the outer braid 18 to the threads 118 of the coupler 110, electrical connection between the outer conductor and/or the outer braid 18 and the port of the device may be accomplished even if the coupler 110 is not fully seated or tightened onto the port of the device.
(33) Referring to
(34) Referring to
(35) In some embodiments, the coaxial cable connector assembly 100 further includes a reservoir rupturing member 123 spaced apart from the reservoir engagement member 120. As the coaxial cable 10 and the reservoir engagement member 120 move forward along the cable channel 162 in the axial direction, the reservoir engagement member 120 is positionable from a disengaged position to an engaged position with respect to the reservoir rupturing member 123. In the disengaged position, the adhesive 184 is encapsulated within the adhesive reservoir 180. In the embodiment depicted in
(36) While in the embodiment depicted in
(37) Referring to
(38) Referring to
(39) In embodiments, the coaxial cable connector assembly 100 includes an inlet guide portion 140 that is positioned rearward of the adhesive reservoir 180 and an exit portion 142 that is positioned forward of the adhesive reservoir 180. In embodiments, the inlet guide portion 140 and the exit portion 142 are structurally configured to receive the inner conductor 12 of the coaxial cable 10. For example, the inlet guide portion 140 and the exit portion 142 may guide the inner conductor 12 of the coaxial cable 10 to pass through the adhesive reservoir 180. In the embodiment depicted in
(40) In some embodiments, the coupler 110 comprises an outer jacket engagement feature 165 that is structurally configured to engage the outer jacket 20 of the coaxial cable 10. The outer jacket engagement feature 165 may assist in allowing the coupler 110 to rotate with respect to the coaxial cable 10, as described in greater detail herein.
(41) To install the coaxial cable 10 to the coupler 110, the inner conductor 12 is inserted into the inlet guide portion 140 and breaks the adhesive reservoir breakable material 182 of the adhesive reservoir 180. As the coaxial cable 10 is further inserted, in embodiments that include the hardener reservoir 190, the inner conductor 12 breaks the hardener reservoir breakable material 192 of the hardener reservoir 190, and the hardener 194 and the adhesive 184 react with one another. The coaxial cable 10 is further inserted through the exit portion 142, which guides the inner conductor 12 to the front portion 114 of the coupler 110, and the exit portion 142 may scrape adhesive 184 from the inner conductor 12 as the inner conductor 12 passes through the exit portion 142.
(42) As the adhesive 184 solidifies, for example by reacting with the hardener 194, the adhesive 184 couples the inner conductor 12 of the coaxial cable 10 to the housing 141. As noted above, the housing 141 is generally captured by the coupler 110, and accordingly, the inner conductor 12 of the coaxial cable 10 is coupled to the coupler 110 through the adhesive 184 and the housing 141. As noted above, the housing 141 is rotatably engaged with the coupler 110, such that the coupler 110 may remain free to rotate with respect to the coaxial cable 10, such that the coaxial cable connector assembly 100 may be coupled to a port of a device.
(43) Accordingly, it should now be understood that embodiments described herein are directed coaxial cable connector assemblies including contained adhesives. The contained adhesives may be released by breaking a breakable material encapsulating the adhesive, and the adhesive generally hardens to couple a coaxial cable to the coaxial cable connector assembly. In some embodiments, the breakable material may be broken by inserting the coaxial cable into the coaxial cable connector assembly. In some embodiments, the breakable material may be broken by a radial force applied to the coaxial cable connector assembly. Contained adhesives may reduce the amount of force required to couple the coaxial cable to the coaxial cable connector assembly, thereby reducing the burden on a user, such as a technician
