This application claims the benefit of U.S. Provisional Application No. 60/816,006, filed Jun. 23, 2006; which application is incorporated herein by reference.
The present disclosure relates generally to devices for use in the telecommunications industry, and various methods associated with such devices. More particularly, this disclosure relates to mounting arrangements for telecommunication panels.
Telecommunication panels are used to provide electrical connections in a wide variety of telecommunication applications. The panels are often housed within and mounted to racks and cabinets, for example. Many racks and cabinets include frames having defined positions at which panels may be mounted. The panels are mounted at the defined panel positions with fasteners.
On many frame systems, panels are mounted to the frame by engaging screws with captive cage nuts provided within the frame. Cage nuts are designed to give a certain amount of float to ensure that manufacturing tolerances experienced with sheet metal frame constructions are accommodated. The cage nuts are typically provided within square holes located in the frame. Providing such a fastening system is time consuming and can lead to misalignment problems when attempting to match holes across the width of the frame.
In general, improvement has been sought with respect to such systems and methods. Accommodations to utilize some existing devices of such systems is also needed.
The present disclosure relates to a mounting arrangement for use with a telecommunications panel and a frame. The mounting arrangement is configured to secure a standard panel to a non-standard frame. A standard panel is a panel that has mounting brackets with mounting holes sizes for receipt of fasteners; which fasteners in conventional applications typically engage cage nuts provided on the frame. A non-standard frame is a frame that does not have cage nuts to which standard panels typically mount.
A variety of examples of desirable product features or methods are set forth in part in the description that follows, and in part will be apparent from the description, or may be learned by practicing various aspects of the disclosure. The aspects of the disclosure may relate to individual features as well as combinations of features. It is to be understood that both the foregoing general description and the following detailed description are explanatory only, and are not restrictive of the claimed invention.

Reference will now be made in detail to various features of the present disclosure that are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.
FIGS. 1-2 and 5 illustrate a mounting arrangement 10 that provides an interconnection between a telecommunications panel 12 (partially represented) and a telecommunications frame 14 (also partially represented). The panel 12 in the illustrated embodiment is a patch panel, however, other types of panels and equipment can be provided with the present mounting arrangement 10 in accordance with the principles disclosed. The frame 14 is a telecommunications rack frame. The mounting arrangement 10 can also be utilized in other systems and structures, such as cabinets and wall boxes, for example.
The present mounting arrangement 10 accommodates securing of a standard panel (e.g., 12 ) relative to a non-standard frame (e.g., 14 ). The non-standard frame 14 includes side frame members 50 (only one shown as the other side frame member is identically constructed). Referring to FIG. 5, the side frame member 50 includes a vertical channel 18 . As shown in FIG. 1, the vertical channel 18 defines a plurality of opposing openings 32 (e.g., holes or slots) located on opposite sides 42 , 44 of the channel 18 . The plurality of openings 32 extends along the length of the vertical channel 18 , generally from a top of the frame to the bottom of the frame.
The present mounting arrangement 10 generally includes a fastener piece 16 sized and configured to fit within the channel 18 of the frame 14 . In use, the fastener piece 16 is laterally pushed within the channel 18 of the frame 14 . The fastener piece 16 is constructed and sized so that the fastener piece 16 can be laterally inserted within the channel 18 from the front of the frame at a desired position; as opposed to accessing the top of the frame and then sliding the piece down the channel to the desired position.
Referring to FIGS. 3 and 4, the fastener piece 16 generally has a front 52 , a rear 54 , a first side 36 and a second opposite side 38 . The fastener piece 16 defines at least one aperture 34 that extends through the fastener piece 16 from the first side 36 to the second opposite side 38 . In the illustrated embodiment, the fastener piece 16 has three apertures 34 .
The mounting arrangement 10 further includes retaining clips 20 disposed within the apertures 34 . The retaining clips 20 are each designed to expand from a first normal state to a second expanded stated. In the normal state, as shown in FIG. 1, the retaining clips 20 do not extend beyond the sides 36 , 38 of the fastener piece 16 so as to not obstruct lateral insertion of the fastener piece 16 within the channel 18 of the frame 14 . As will be described in greater detail hereinafter, in the expanded state, the retaining clip 20 extends through the aperture 34 of the fastener piece 16 to engage the opposing openings 32 of the side frame member 50 , as shown in FIG. 2.
Referring still to FIGS. 3 and 4, a fastener hole 28 is formed in the front 52 of the fastener piece 16 . In the illustrated embodiment, three fastener holes 28 (e.g., three threaded holes) are provided, each hole 28 being located in correspondence to an aperture 34 and a retaining clip 20 . In an alternative embodiment, as shown in FIG. 6, a fastener piece 46 may include only one fastener hole 48 (e.g., a single threaded hole) and only one corresponding retaining clip 20 .
Referring now to FIG. 6, one embodiment of the retaining clip 20 is illustrated. The retaining clip 20 of this fastener piece 46 is identical to those used in the fastener piece 16 of FIGS. 1-5. The retaining clip 20 is a U-shaped clip having first and second arms 56 , 58 that define first and second clip ends 60 , 62 . The retaining clip 20 further includes transverse tabs 40 that extend outward from the first and second arms 56 , 58 (e.g., at the first and second clip ends 60 , 62 ).
Referring again to FIG. 5, when affixing a panel 12 to the frame 14 , the fastener piece 16 is positioned within the channel 18 and the panel 12 aligned to the fastener piece 16 . In particular, a mounting through hole 26 of the panel 12 is aligned with one of the fastener holes 28 of the piece 16 . A fastener 24 is then inserted through the through hole 26 formed in the panel 12 and threaded into the fastener hole 28 of the fastener piece 16 .
Referring back to FIG. 2, as the fastener 24 threads into the fastener hole 28 of the piece 16 , the retaining clip 20 expands from the first normal state to the second expanded state to secure the panel 12 in a position relative to the frame 14 . That is, the turning action and threading engagement of the fastener 24 causes the first and second clip ends 60 , 62 of the retaining clip 20 to deflected and expanded outward through the aperture 34 to engage the openings 32 formed within the channel 18 of the frame 14 . In particular, an end 30 (FIG. 1) of the fastener 24 contacts the arms 56 , 58 and pushes the transverse tabs 40 radially outward from the sides 36 , 38 of the fastener piece 16 to engage the frame openings 32 .
The engagement between the deflected retaining clip 20 and the openings 32 of the frame 14 vertically support and secured the panel 12 relative to the frame 14 . Vertical alignment of the fastener piece 16 is achieved via the pre-set openings 32 formed in the frame 14 . As can be understood, removal of the panel 12 is performed by simply reversing the above assembly process.
In one embodiment, the fasteners 24 of the mounting arrangement 10 are threaded, quarter-turn fasteners that require only ¼ turn to contact and outwardly expand the retaining clip 20 of the fastener piece 30 . The quarter-turn fasteners provide for quick and easy assembly of the panel 12 to the frame 14 .
The above specification provides a complete description of the present invention. Since many embodiments of the invention can be made without departing from the spirit and scope of the invention, certain aspects of the invention reside in the claims hereinafter appended.
