Description

FIELD OF THE DISCLOSURE

The present disclosure relates to fiber optic connector assemblies (e.g., fiber cassette or adapter modules) for use in communication systems and, more particularly, to media patching systems having connector assemblies that include a slide lock member.

BACKGROUND OF THE DISCLOSURE

In general, devices for interfacing with high frequency data transfer media are known. See, e.g., U.S. Pat. Nos. 8,439,702; 8,672,709 and 8,731,364, the entire contents of each being hereby incorporated by reference in their entireties.

In general, commercial buildings require an effective and efficient telecommunications infrastructure to support the wide variety of services that rely on the transport of information. Typically, wiring systems within buildings are terminated at a location where they may be interconnected with one another, and/or to other cabling systems or telecommunications equipment. Cables are often terminated on wire panels or patch panels or the like, which can be mounted to racks or to some other location/structure.

Patch panels are known in the field of data communication systems. See, e.g., U.S. Pat. No. 8,106,311, the entire contents of which is hereby incorporated by reference in its entirety. Some other exemplary assemblies/systems in this general field are described and disclosed in U.S. Pat. Nos. 7,697,811; 7,983,038; 8,184,938; 8,398,039; 8,758,047; and U.S. Patent Publication No. 2015/0366092, the entire contents of each being hereby incorporated by reference in their entireties.

A patch panel generally provides a plurality of network ports incorporated into a structural element that connect incoming and outgoing lines of a communication/electrical system (e.g., a local area network (LAN) or the like). Typical patch panels are mounted hardware units that include a plurality of port locations, and utilize cables for interconnections. A patch panel can use patch cords to create the interconnections. Patch panel systems are generally intended to facilitate organization and management in implementing telecommunications wiring systems (e.g., for high speed data networks).

In general, many rows of cabinets or racks typically fill a data center or telecommunications room. Patch panels affixed to a rack and/or a telecommunications room provide convenient access to telecommunication devices (e.g., servers) within the rack or room. As the demand for the use of telecommunication devices rapidly grows, space for such devices becomes limited and/or expensive.

A constant need exists among manufacturers to develop connector assemblies (e.g., fiber cassette or adapter modules) for use in communication systems or the like that include improved features and structures.

Thus, an interest exists for improved connector assemblies that are easily secured and/or unsecured to or from a media system (e.g., to or from a panel member), and related methods of use. These and other inefficiencies and opportunities for improvement are addressed and/or overcome by the assemblies, systems and methods of the present disclosure.

With reference to FIGS. 8-15, there is illustrated an embodiment of an exemplary media patching system 10 according to the present disclosure.

Panel members 12 (e.g., patch panel members/multi-connector panel members 12) can be utilized with (e.g., mounted to) system 10 to support multiple media connections. As described and disclosed in U.S. Patent Pub. No. 2015/0366092, system 10 may or may not include top covers, a lower cable management plate, bracket members, and a door assembly. System 10 can be configured to be mounted with respect to a supporting structure (e.g., a rack) or the like. It is noted that exemplary media patching systems 10 can be adapted for use in conjunction with a rack (e.g., network or server rack) or the like, although the present disclosure is not limited thereto. Rather, the disclosed media patching systems 10 can be adapted for use in conjunction with other structures, such as, for example, frames, cabinets, supporting structures, or other structures that stand to benefit from proximate cable management functionality. For ease of disclosure, the potential structures to which the disclosed systems 10 may be mounted are collectively referred to as “racks.” However, it is to be understood that the present disclosure is not limited by or to implementations wherein the disclosed systems 10 are mounted with respect to, or used in conjunction with, a rack, but may be mounted with respect to, or used in conjunction with other structures/units (e.g., structures/units associated with cable routing).

As noted, panel members 12 can be utilized with system 10 to support multiple media connections. As shown in FIG. 5, exemplary panel member 12 has a front panel surface/segment 15 that includes a plurality of apertures 13 therethrough. As discussed in further detail below, each aperture 13 is typically configured and dimensioned to have a connector assembly 14, 14′ mounted with respect thereto. It is noted that panel member 12 can take a variety of shapes, forms and/or geometries, and can include any suitable number of apertures 13.

In exemplary embodiments and as shown in FIG. 5, it is noted that at least surfaces 15A, 15B and 15C of panel member 12 are each aligned in the same plane. As such and as discussed further below, when connector assembly 14, 14′ is mounted/secured to panel member 12, this alignment of the planar surfaces of surfaces 15A, 15B and 15C substantially eliminates or reduces movement (e.g., up, down or sideways wobble) of the connector assembly 14, 14′ once it is secured in place relative to panel member 12 (e.g., FIGS. 14-16, and the associated discussion below).

As noted, one or more connector assemblies 14, 14′ can be mounted with respect to panel member 12 (e.g., with one aperture 13 configured to house/mount to one assembly 14, 14′). More particularly, each connector assembly 14, 14′ typically includes a slide lock member 16 (FIGS. 6-7) that is configured to releasably secure the connector assembly 14, 14′ to panel member 12. Panel member 12 can include any number/combination of connector assemblies 14, 14′ mounted thereon (e.g., one, two, three, four, six, twelve, a plurality, etc.).

As shown in FIGS. 1-3, exemplary connector assembly 14 takes the form of a fiber optic cassette 14 having a plurality of fiber optic ports/adapters 18 (e.g., eight ports/adapters 18) for mating with fiber optic connectors. It is noted that connector assembly 14 can include any suitable number of fiber optic ports/adapters 18.

In certain embodiments, connector assembly 14 is an eight fiber front load cassette 14, and includes two LC quad adapters members for the eight ports/adapters 18. As shown in FIG. 3, connector assembly 14 can be a cassette 14 that includes a rear top wall/cover member 17, a rear MPO adapter 19, and an internal harness (e.g., that includes eight LC connectors connecting to a MPO connector by way of eight optical fibers).

In exemplary embodiments and as shown in FIGS. 1-3, connector assembly 14 includes housing 20 that extends from a first end 22 to a second end 24, and includes a mounting flange 26 extending from the housing 20, with the mounting flange 26 positioned between the first and second ends 22, 24. In general, first end 22 of housing 20 is configured to house at least a portion of the ports/adapters 18.

Exemplary housing 20 includes a first rear side wall 28 that extends from the mounting flange 26 to the second end 24, and includes a second rear side wall 30 that extends from the mounting flange 26 to the second end 24.

Housing 20 also includes a rear top wall/cover member 17 that extends from the mounting flange 26 to the second end 24. It is noted that rear top wall/cover member 17 may or may not be removable.

Housing 20 also includes a front top wall 32 that extends from the mounting flange 26 to the first end 22.

As shown in FIGS. 1-3, each rear side wall 28, 30 includes a top mounting member 58A and a bottom mounting member 58B. In exemplary embodiments, it is noted that members 58A and 58B are mirror images of one another on each side wall 28, 30. In general, each mounting member 58A, 58B extends from wall 28, 30, and each includes a forward locking knob 60.

As shown in FIG. 4, exemplary mounting flange 26 includes a slot 34 therethrough. In general, slot 34 is positioned above front top wall 32 of housing 20.

The bottom portion (e.g., central bottom portion) of the slot 34 includes a groove 36 that extends from the front side 27 of mounting flange 26 and extends rearwardly along and into rear top wall 17.

As noted, connector assembly 14 includes slide lock member 16. As shown in FIGS. 6-7, exemplary slide lock member 16 extends from a first end 38 to a second end 40, and includes a top side 42 and a bottom side 44. The first end 38 of member 16 can include a handle member 52.

Each side of second end 40 of slide lock member 16 includes a movable hook member 46 (e.g., snap hook members 46). The rear end of each hook member 46 includes a hooking element 47 that extends outwardly.

The top side 42 of slide lock member 16 includes an abutment wall 48, and one or more extending members 50. In exemplary embodiments, member 16 includes two extending members 50, and each extending member 50 takes the form of a leaf-spring member/feature 50 or the like, as discussed further below.

The second end 40 of bottom side 44 of member 16 includes an alignment pin 54. An alignment wall 55 extends from the alignment pin 54 toward the first end 38. Positioned along alignment wall 55 is an engagement wall 56 that extends transverse to the alignment wall 55.

In use and with reference to FIGS. 4, 6 and 7, a user can position the slide lock member 16 over the front top wall 32, and position the alignment pin 54 within the groove 36. The two hook members 46 can be positioned so that the hooking elements 47 are positioned through the slot 34 of the mounting flange 26 to releasably retain the slide lock member 16 to connector assembly 14 (FIGS. 3, 8 and 9).

A user can then position the second end 24 of housing 20 of connector assembly 14 through a desired aperture 13 of panel member 12 (FIGS. 8-9). In this position, the rear end of each top mounting member 58A is positioned above a respective extending member 21 of panel member 12, and the rear end of each bottom mounting member 58B is positioned below a respective extending member 21 of panel member 12.

A user can then move the connector assembly 14 rearwardly (e.g., in the direction of Arrow R of FIG. 9) with each member 58A travelling above extending member 21 and with each member 58B travelling below extending member 21 until the rear side 29 of mounting flange 26 abuts against the front surface 15 of panel member 12 (FIGS. 10-11). In such a position, it is noted that each hooking element 47 can be positioned within and/or through a respective recess 23 of panel member 12.

A user can then move the connector assembly 14 downwardly (e.g., in the direction of Arrow D of FIG. 11) until the locking knob 60 of each member 58A is positioned behind and against a respective extending member 21 (FIGS. 12-13).

Next, a user can move the slide lock member 16 rearwardly (e.g., in the direction of Arrow R of FIG. 13) through the slot 34 of the mounting flange 26 with the alignment pin 54 travelling within groove 36 until the abutment wall 48 abuts against the front side 27 of mounting flange 26 and/or until the engagement wall 56 engages/abuts against the front side 27 of mounting flange 26 and/or until the alignment pin 54 reaches the rearward end of groove 36 (FIGS. 14-16). In such a position as shown in FIGS. 14-16, the slide lock member 16 releasably locks the connector assembly 14 to the panel member 12, with the slide lock member 16 positioned above the connector assembly 14 and through the slot 34 of the mounting flange 26, thereby preventing each locking knob 60 of each member 58A from moving upwardly away from engagement from each respective extending member 21 (FIGS. 15-16).

When the slide lock member 16 is moved rearwardly (e.g., in the direction of Arrow R of FIG. 13) through the slot 34 of the mounting flange 26 until the member 16 reaches the position shown in FIGS. 14-16, it is noted that the extending members 50 of slide lock member 16 are configured to take up tolerance against panel member 12 to releasably lock the connector assembly 14 to the panel member 12.

To unsecure the releasably locked connector member 14 from the panel member 12 as shown in FIGS. 14-16, a user would first move the slide lock member 16 forwardly (e.g., in the direction of Arrow F in FIG. 15) until the slide lock member 16 reached the position shown in FIGS. 12-13. A user could then move the connector member upwardly (e.g., in the direction of Arrow U of FIG. 13) until the connector member 14 reached the position shown in FIGS. 10-11. The user can then continue moving the connector assembly 14 in the direction of Arrow F until the connector assembly 14 was removed from aperture 13 of panel member 12.

As shown in FIGS. 17-18, it is noted that connector assembly 14′ can take the form of an adapter module 14′ and can be secured and unsecured relative to panel member 12 via slide lock member 16 as similarly discussed above in connection with connector assembly 14.
