[0042] Turning now to the drawings, FIG. 1 illustrates one embodiment of a connector assembly in accordance with the disclosure and generally identified by reference numeral 10. The connector assembly 10 includes a plug assembly 12 and a receptacle assembly 200 that is configured to be selectively coupled to the plug assembly 12, as will be described in further detail hereinbelow. Although generally described herein as having both electrical contacts and optical fibers, the disclosure is not so limited. In embodiments, the connector assembly may only include optical fibers (and does not necessarily include electrical contacts). It is envisioned that the connector assembly 10 may be utilized in a medical environment in some applications, and in some embodiments, may be utilized to deliver light therapy to a patient. It is contemplated that some or all of the various components of the connector assembly 10 may be formed from materials compatible for use as a medical device, although the connector assembly 10 may be formed from any suitable material without departing from the scope of the disclosure. Alternatively, the connector assembly 10 may be used in any suitable application.
[0043] With additional reference to FIGS. 2 and 3, the plug assembly 12 includes a cable bundle 14 operably coupled to a plug 40. The cable bundle 14 includes first optical ferrules 16, second optical ferrules 18, optical fibers 20, first electrical contacts 22, electrical wires 24, second electrical contacts 26, an electrical plug 28, and an insulatingSIKCP78509PC00(39717-139)6tube 30. Each optical ferrule of the first optical ferrules 16 is configured receive and retain a respective optical fiber of the optical fibers 20 therein. In this manner, the optical fibers 20 are coupled to the optical ferrules 16 using any suitable means, such as, for example, adhesives, mechanical fasteners, press-fit, friction fit, and mechanical capturing. In one non-limiting embodiment, the optical fibers 20 are bonded to the optical ferrules 16 using an epoxy resin.
[0044] The first optical ferrules 16 and the second optical ferrules 18 are substantially similar to one another and therefore, only the first optical ferrules 16 will be described in detail herein in the interest of brevity. Although generally described as being substantially similar to the first optical ferrules 16, it is envisioned that the second optical ferrules 18 may be the same or different from the first optical ferrules 16 without departing from the scope of the disclosure. The first optical ferrules 16 may be any suitable optical ferrule configured to retain and align the optical fibers 20, may be formed from any suitable material, and may be any suitable size. In one non-limiting embodiment, the first optical ferrules 16 are LC (e.g., for example, Lucent, Little, and Local connectors) connectors formed from ceramic (e.g., for example, Zirconia) ferrules coupled to nickel plated brass flanges. It is contemplated that the cable bundle 14 may include any number of first optical ferrules 16 and optical fibers 20, and in some embodiments, may include twenty- four first optical ferrules 16 and corresponding optical fibers 20 without departing from the scope of the disclosure. Although generally described as being substantially similar to one another, it is envisioned that one or more of the first optical ferrules 16 may be the same or different from one another.
[0045] The optical fibers 20 are configured to transmit light generated by a light source (not shown) to an end face 144 (shown in FIG. 8) of the plug body 42. The optical fibers 20 are multi-mode optical fibers having a Numerical Aperture (NA) of approximately 0.22, although it is envisioned that the optical fibers 20 may be single-mode optical fibers having any suitable NA, or combinations thereof, depending upon the design needs of the connector assembly 10. It is envisioned that the optical fibers 20 may be formed from any suitable material, such as, for example, Silica, Fluorine-doped Silica, Fluoride glass,SIKCP78509PC00(39717-139)7Phosphate glass, and Chalcogenide glass, having any suitable hydroxyl group (OH) concentration, any suitable size, and any suitable spectral range. In one non-limiting embodiment, the optical fibers 20 are formed from Silica having a low OH, a 200 micron (pm) core, 220 pm cladding, and having a spectral range of between about 400-2400 nanometers (nm). It is contemplated that the optical fibers 20 may be configured to transmit any amount of power without departing from the scope of the disclosure. In one non-limiting embodiment, the optical fibers 20 may transmit a power of between about 7.54 W and 20.27 W and individual optical fibers of the optical fibers 20 may transmit a power of between about 314 mW and 580 mW. In embodiments, each optical fiber of the optical fibers 20 is disposed within a respective jacket or insulator 23 to individually insulated insulate each optical fiber from one another (FIG. 10A).
[0046] Continuing with FIGS. 2 and 3, the first electrical contacts 22 may be any suitable electrical contact configured to retain respective electrical wires 24 therein and maintain electrical communication between the first electrical contacts 22 and the electrical wires 24. It is envisioned that the first electrical contacts 22 may be coupled to the electrical wires 24 using any suitable means, such as adhesives, mechanical fasteners, crimping, soldering, welding, and combinations thereof. The electrical wires 24 are configured to transmit electrical energy and / or signals from an energy and / or signal source (not shown) separately and distinctly from the light transmitted through the optical fibers 20. As can be appreciated, the type and size of the electrical wires 24 may be selected based on the design needs of the connector assembly 10, and one or more of the electrical wires 24 may be different than the others without departing from the scope of the disclosure. In one nonlimiting embodiment, the electrical wires 24 include six individual 28 AWG wires, where four wires form a Universal Serial Bus (USB) cable and two wires form hook-up wires.
[0047] The second electrical contacts 26 may be the same or different than the first electrical contacts 22, and therefore, will not be described in detail herein in the interest of brevity. The electrical plug 28 is operably couplable to the second electrical contacts 26 using any suitable means, such as press-fit, friction-fit, mechanical fasteners, mechanical coupling (e.g., for example, a detent, tabs, a latch, and combinations thereof), adhesives,SIKCP78509PC00(39717-139)8soldering, and combinations thereof. Although generally illustrated as a printed circuit board connector, it is envisioned that the electrical plug 28 may be any suitable connector or plug depending upon the design needs of the connector assembly 10.
[0048] The insulating tube 30 defines a generally tubular shape and is configured to receive the optical fibers 20 and the electrical wires 24. In this manner, the optical fibers 20 and the electrical wires 24 are disposed within an interior portion of the insulating tube 30 and extend into, and out of, the insulating tube 30. The insulating tube 30 is configured to be received within a portion of the plug strain relief 160 resulting in the insulating tube 30 being interposed between the plug strain relief 160 and the optical fibers 20 and the electrical wires 24. It is envisioned that the insulating tube 30 may be formed from any suitable material without departing from the scope of the disclosure. In one non-limiting embodiment, the insulating tube 30 is formed from Polytetrafluoroethylene (PTFE).
[0049] With continued reference to FIGS. 2 and 3, and with additional reference to FIGS. 4 and 5, the plug 40 includes a plug body 42, a plug retainer 90, a plug insulator 120, and a plug strain relief 160. The plug body 42 defines an elongate body extending between opposed first and second end portions 46 and 48. The plug body 42 includes a protrusion 50 disposed adjacent to the first end portion 46. The protrusion 50 extends towards the second end portion 48 and terminates at a radially outward extending flange 52. Although generally illustrated as defining a D-shaped profile (FIG. 11), it is envisioned that the protrusion 50 may define any suitable profile without departing from the scope of the disclosure. The plug body 42 includes an inner surface 54 defining a cavity 56 extending through the first end portion 46 and the second end portion 48. Although generally illustrated as defining a profile that is generally complementary to the profile of the protrusion 50, the profile of the inner surface 54 (FIG. 12) may be the same or different than the profile of the protrusion 50 without departing from the scope of the disclosure. A longitudinally extending groove 58 is defined in the inner surface 54 of the cavity 56 in juxtaposed relation to the linear portion of the D-shaped profile of the inner surface 54 (FIG. 11). The longitudinally extending groove 58 extends through the second end portion 48 towards the first end portion 46 and terminates at a wall 60. The wall 60 is disposed inSIKCP78509PC00(39717-139)9juxtaposed and spaced relation to the first end portion 48 and as will be described in further detail hereinbelow, is configured to abut a corresponding feature of the plug insulator 46 to inhibit further longitudinal movement of the plug insulator 46 towards the first end portion 46 and inhibit rotational movement of the plug insulator 46 relative to the plug body 42.
[0050] A latching mechanism 62 is hingedly coupled to the plug body 42 and includes a protuberance 64 extending radially outward from an outer surface 66 of the radially outward extending flange 52 and a tab 68 operably coupled to the protuberance 66. The tab 68 is disposed in spaced relation to the protuberance 64 in a direction towards the first end portion 46. The tab 68 extends radially outward from an outer surface 70 of the protrusion 50 of the plug body 42 and defines a generally triangle shaped profile. In this manner, contact with the hypotenuse or ramp portion 72 of the tab 68 causes the tab 68 to be depressed or otherwise move towards an interior portion of the plug body 42. A generally linear side wall 74 of the tab 68 is configured to catch or otherwise be received in a corresponding feature of the receptacle assembly 200 to selectively inhibit movement of the plug assembly 40 relative to the receptacle assembly 200 and vice versa. The protuberance 64 is hingedly coupled to the plug body 42 at a position adjacent to the second end portion 48. In this manner, depressing or otherwise urging the protuberance 64 towards the outer surface 66 of the radially outward extending flange 52 causes the tab 68 to transition from a position where the tab 68 protrudes past the outer surface 70 of the protrusion 50 to a position where the tab 68 is recessed from or level with the outer surface 70.
[0051] It is envisioned that the protuberance 64 may be hingedly coupled to the plug body 42 using any suitable means, such as, for example, a barrel hinge, a living hinge, and combinations thereof, and in embodiments, may include a biasing member (e.g., for example, coil spring, a flat spring, a torsion spring, and combinations thereof) to bias the tab 68 towards an initial position where the tab 68 protrudes past the outer surface 70 of the plug body 42. In one non-limiting embodiment, the latching mechanism 62 is hingedly coupled to the plug body 42 via a living hinge. It is envisioned that the living hinge maySIKCP78509PC00(39717-139)10be a unitary part of the plug body, where the plug body is formed from a resilient material, may be a part of the protuberance 64 that is operably coupled to the plug body 42 using any suitable means, such as, for example, adhesives, welding, press-fit, friction-fit, mechanical fasteners, and combinations thereof, and may be a separate component from both the plug body 42 and the protuberance 64, being formed from a resilient material that is operably coupled to each of the plug body 42 and the protuberance 64 using any suitable means, such as, for example, adhesives, welding, press-fit, friction-fit, mechanical fasteners, and combinations thereof.
[0052] Continuing with FIGS. 2-5, the plug body 42 includes an extension 76 extending between the second end portion 48 and the radially outward extending flange 52. Although generally illustrated as defining a circular profile, it is envisioned that the extension 76 may define any suitable profile, and in embodiments, may define a profile that is the same or different than the profile of the protrusion 50. A plurality of crenellations 78 is disposed on and extending radially outward from the extension 76. The plurality of crenellations 78 partially encircle the extension 76 such that the portion 80 of the extension 76 adjacent to the protuberance 64 is generally smooth or otherwise free from crenellations. Although generally described as partially encircling the extension 76, it is envisioned that one or more of the plurality of crenellations 78 may fully encircle the extension 76, encircle any portion of the extension 76, or form a non-contiguous profile about the circumference of the extension 76 without departing from the scope of the disclosure. As will be described in further detail hereinbelow, the plurality of crenellations 78 is configured to selectively engage a corresponding plurality of features of the plug strain relief 160.
[0053] Turning to FIGS. 6 and 7, the plug retainer 90 defines an elongate body extending between opposing first and second end portions 92 and 94. The plug retainer 90 defines an outer surface 96 extending between the first and second end portions 92, 94 and defining a profile that is generally complimentary to the profile of the inner surface 54 of the plug body 42. The outer dimension of the outer surface 96 of the plug retainer is less than the inner dimension of the inner surface 54 of the plug body 42, which, in combinations with the complimentary profiles of the outer surface 96 and the inner surfaceSIKCP78509PC00(39717-139)1154 enables a portion of the plug retainer 44 to be received within the cavity 56 of the plug body. Although generally described as having a profile complementary to the profile of the inner surface 54 of the plug body 42, it is envisioned that the outer surface 96 of the plug retainer 90 may define any suitable profile, and in embodiments, may be the same or different than the profile of the inner surface 54 without departing from the scope of the disclosure.
[0054] The plug retainer 90 includes a cap 98 disposed on the outer surface 96. The cap 98 is disposed adjacent to the second end portion 94 and extends towards the first end portion 92 terminating at an annular flange 100. It is envisioned that the annular flange 100 may be disposed at any position along the length of the plug retainer 90 depending upon the design needs of the connector assembly 10. A tab or resilient finger 102 is disposed on and extends longitudinally from the annular flange 100 towards the first end portion 92 and terminates at an end wall 104. The resilient finger 102 is disposed in spaced relation to the outer surface 96 and defines a slot 106. The slot 106 is configured to slidably receive a portion of the extension 76 of the plug body 42 when the plug retainer 90 is coupled to the plug body 42 (FIG 11). A plurality of crenellations or radially extending ridges 108 is disposed on an outer surface 110 of the cap 98. As will be described in further detail hereinbelow, the plurality of crenellations 108 is configured to engage corresponding features of the plug strain relief 160 to selectively coupled the plug strain relief 160 to the plug retainer 90. In embodiments, the plug retainer 44 may include one or more tabs 112 disposed on end extending longitudinally from the annular flange 100 that are configured to selectively retain a portion of the radially outward extending flange 52 of the plug body 42. The plug retainer 90 includes an inner surface 114 defining a through-bore 116 extending through the first end portion 92 and the second end portion 94. The through-bore 116 is configured to receive the cable bundle 14 and enable the cable bundle to extend into the second end portion 94 and exit the first end portion 92 depending upon the design needs of the connector assembly 10.
[0055] Returning to FIG. 3 and with additional reference to FIGS. 8-12, the plug insulator 120 defines an outer surface 122 extending between opposed first and second endSIKCP78509PC00(39717-139)12portions 124 (FIG. 9) and 126. The plug insulator 120 defines a profile that is generally complimentary to the profile defined by the inner surface 54 of the plug body 42, although it is contemplated that the plug insulator 120 may define any suitable profile without departing from the scope of the disclosure. The outer dimension of the plug insulator 120 is smaller than or generally equal to the dimension of the cavity 56 of the plug body 42, enabling the plug insulator 120 to be received within the cavity 56. The D-shape profile of the plug insulator 120 defines a generally planar portion 128. A recess 130 is defined through the second end portion 126 and the outer surface 122 and extends longitudinally towards the first end portion 124 terminating at a side wall 132. The recess 130 is positioned on the planar portion 128 to receive a portion of the latching mechanism 62 (e.g. , for example, a portion of the tab 68) when the protuberance 64 is depressed (FIG. 5). In this manner, the recess 130 enables the tab 68 to transition from a first, un-depressed position to a second, depressed position to lock and unlock the plug assembly 42 from the receptacle assembly 200.
[0056] A protuberance 134 is disposed on and extends radially outward from the outer surface 122. The protuberance 134 is disposed in juxtaposed relation to the recess 130 and extends longitudinally between the first and second end portions 124, 126. The protuberance 134 defines a profile that is generally complimentary to the profile of the longitudinally extending groove 58 (FIG. 5) of the plug body 42 to enable the protuberance 134 to be slidably received within the longitudinally extending groove 58 as the plug insulator 120 is advanced within the cavity 56 of the plug body 42. As can be appreciated, the protuberance 134 and the longitudinally extending groove 58 cooperate to inhibit rotation of the plug insulator 120 relative to the plug body 42 and vice versa and maintain alignment of the first optical ferrules 16 with the plug body 42.
[0057] Continuing with FIGS. 8-12, the plug insulator 120 defines a counterbore 136 extending through the second end portion 124 and terminating at a planar surface 136. The counterbore 136 defines a profile that is generally complimentary to the profile of the outer surface 122, although it is envisioned that the counterbore 136 may define any suitable profile without departing from the scope of the disclosure. A shelf or boss 140 is disposedSIKCP78509PC00(39717-139)13on the planar surface 138 and extends towards the second end portion 126. Although generally illustrated as being recessed (e.g., for example, not flush) from the second end portion 126, it is contemplated that the boss 140 may terminate at any location between the planar surface 138 and the second end portion 126 depending on the design needs of the connector assembly 10. A notch 142 is formed within a portion of the boss 140 extending longitudinally from the planar surface 138 and through the second end portion 126. As can be appreciated, the notch 142 enables additional optical fibers 20 to be included in the cable bundle 14 and increased optical cable density as compared to the plug insulator 120 not having the notch 142.
[0058] A plurality of apertures 144 is defined through the first end portion 124 and the planar surface 138 of the counterbore 136. The plurality of apertures 144 is disposed in a nested configuration, enabling a greater density of apertures to be defined through the plug insulator 120 as compared to the plurality of apertures 144 being disposed in a grid or other configuration. As can be appreciated, the nested configuration enables the plurality of apertures 144 to be disposed a greater distance away from one another while increasing the density of the plurality of apertures 144 within a given space as compared to a grid or circular pattern, providing advantageous heat dissipation qualities and high-power capabilities. It is envisioned that the plurality of apertures 144 may be disposed in any orientation and any center-to-center distance without departing from the scope of the disclosure. In one non-limiting embodiment, the plurality of apertures includes a center-to-center spacing of between about 3.00 mm to 3.50 mm.
[0059] The plurality of apertures 144 is configured to receive and retain respective first optical ferrules 16 using any suitable means, such as, for example, mechanical securement, adhesives, mechanical fasteners, press-fit, friction-fit, and combinations thereof. As can be appreciated, the plug insulator 120 may include any number of apertures 144, which may be the same or different than the number of optical fibers 20 used in the cable bundle 14. In one non-limiting embodiment, the plurality of apertures 144 includes twenty- four apertures.
