Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a panel or plate for mounting a connection module in a network rack. More particularly, the present invention relates to a mounting plate, which allows the connection module to be recessed in the mounting plate to a substantially flush position with respect to a front face of the mounting plate, while providing a sturdy mounting structure which is inexpensive to fabricate and easy to install.

2. Description of the Background

Mounting plates to attach electrical and/or optical connection modules to a network rack are known in the prior art. The typical network rack includes first and second network rack rails which are spaced nineteen to twenty-one inches apart. The mounting plate is a generally flat rectangular plate and is attached to the first and second rack rails and extends between the first and second network rack rails. One or more windows are formed within the mounting plate and one or more features surround each window to secure a connection module within the window.

For example, FIG. 1 shows a mounting plate 12 in accordance with the prior art of U.S. Pat. No. 7,488,205, which is owned by the current assignee and is herein incorporated by reference. The mounting plate 12 includes left and right sides 18 and 18A with two mounting openings 19 proximate each of the left and right sides 18 and 18A. The openings 19 accept fasteners 7 to secure the left and right sides 18 and 18A to left and right network rack rails 5 and 5A. Four windows 15-1, 15-2, 15-3 and 15-4 are formed in the mounting plate 12 with notched stanchions defining the lateral sides of the windows 15. The notches accept snap features of the modules to be mounted to the plate 12. Other designs of mounting plates, which are used to attached connection modules to network rack rails, can be found in U.S. Pat. Nos. 6,347,715; 6,537,106 and 6,974,348, which are herein incorporated by reference.

A known type of connection unit 21 is a feed-through terminal block sold under Model No. 3211776 by Phoenix Contact of Middletown, PA. The connection unit 21 is used to electrically connect one end of a first electrical wire to another end of a second electrical wire. As shown in FIG. 2, the Model No. 3211776 connection units 21 can be stacked into an array between first and second end caps 23 and 25 to form a termination block or connection module 27 to connect respective ends of forty-eight electrical wires in a first set to respective ends of forty-eight electrical wires in a second set. Groups of eight connection units 21 may be separated by divider plates 29 within the connection module 27.

Each connection unit 21 includes a first push-in receptacle 31 in a front face of the connection unit 21 near a top 32 of the connection unit 21 to receive an end of an electrical wire of the first set. Each connection unit 21 also includes a second push-in receptacle 33 in the front face of the connection unit 21 near a bottom 34 of the connection unit 21 to receive an end of an electrical wire of the second set. Jumper slots, test ports and/or labels may be provided in or on the front face of the connection unit 21 between the first and second push-in receptacles 31 and 33.

A galvanized steel DIN rail 35 has first and second off-set flanges 37 and 39 along its longitudinal edges. Equally spaced oval openings 41 are formed along a middle line between the first and second off-set flanges 37 and 39. The first and second off-set flanges 37 and 39 of the rail 35 are slid into first and second guide channels 43 and 45 formed on a rear face of the connection units 21, the divider plates 29 and/or the first and second end caps 23 and 25.

The connection module 27 may be slid to a desired location longitudinally along the rail 35. The longitudinal length of the rail 35 is about nineteen to twenty-one inches between first and second lateral ends 47 and 49, so that the rail 35 may be attached to the left and right network rack rails 5 and 5A of FIG. 1 by passing fasteners 7 though the oval openings 41 proximate the first and second lateral ends 47 and 49 of the rail 35.

A particularly safe way to transfer high voltage power from a source to a destination is under development and will be known as digital voltage or class 4 power. Class 4 power sends rapid pulses of high voltage DC current, e.g., 400 volts. The destination receives the pulses, which may be reduced due to some voltage drop over a long transmission line. The destination has equipment to convert the received DC voltage pulses into a new supply voltage which is suitable for the equipment at the destination, e.g., a 240 volt or 120 volt AC signal or a 12, 24 or 48 volt DC signal. If any irregularity occurs in the pulses between the source and destination, e.g., due to an intermittent short or open circuit condition, the source immediately, e.g. within a few milliseconds, stops sending the high voltage DC voltage pulses to avoid an unsafe condition.

Several background art references show systems for providing safe, high voltage pulses, e.g., exceeding 300 VDC. Such background art can be found in U.S. Pat. Nos. 8,781,637; 9,184,795; 9,419,436; 9,853,689; 9,893,521; 10,468,879; 10,541,543 and 10,714,930, and in US Published Application Nos. 2017/0229886; 2018/0313886; 2020/0295559 and 2021/0063447, which are owned by VoltServer of East Greenwich, Rhode Island, and are herein incorporated by reference.

In the class 4 power systems, a source unit that produces the pulses of high voltage DC current has plural electronic transmission cards, e.g., four transmission cards, which each have first and second output terminals. A destination unit that receives the high voltage DC current has plural electronic reception cards, e.g., four reception cards, which each have first and second input terminals.

The source unit may be mounted to the left and right network rack rails 5 and 5A. The connection module 27 of FIGS. 2 and 3 can also be mounted to the left and right network rack rails 5 and 5A. The connection module 27 is well suited to electrically connect jumper wires from the transmission cards of one or more source units to electrical wires at first ends of one or more transmission cables, which carry the power to one or more destination units.

SUMMARY OF THE INVENTION

The applicant has appreciated drawbacks with the designs of the connection modules and mounting plates of the prior art.

One drawback is that the connection module 27 created by stacking the Model No. 3211776 connection units 21 extends forwardly from the rail 35 because the first and second guide channels 43 and 45 are formed on the rear face of the connection units 21. When the rail 35 is connected to the left and right network rack rails 5 and 5A, the front face of the connection module 27 protrudes away from a plane of the left and right network rack rails 5 and 5A. Hence, the top 32 of the connection module 27 extends forward like a shelf to collect dust and debris.

Further, the height of the connection module 27 is about 2.2 inches, whereas the height of the rail 35 is about 1.2 inches. Therefore, gaps are formed to the lateral sides of the connection module 27 when it is mounted to the left and right network rack rails 5 and 5A. The gaps allow visibility to the wires and cabling inside and behind the network rack and do not present a clean and organized appearance.

Also, the extended length of the rail 35 to the left side is subject to flexure, e.g., bending, when a wire ends are pushed into the first and second push-in receptacles 31 and 33, and/or when jumpers/fuses and testing probes are inserted into the jumper slots and test ports on the front face of the connector module 27.

It is an object of the present invention to address the drawbacks appreciated above. It is an object to provide a stronger mounting system for the connector module 27, which is less susceptible to flexure during wiring and testing operations. It is a further object of the present invention to provide a mounting system for the connector module 27, which moves the front face of the connection module 27 rearwardly to a more flush, if not substantially or fully flush, position relative to the left and right network rack rails 5 and 5A. Moreover, it is an object of the present invention to provide a mounting system for the connector module 27, which closes gaps and improves the appearance of connector module 27 within the network rack by presenting a more integrated and solid structure.

These and other objectives are accomplished by a mounting plate which supports a connection module for attachment to a pair of first and second network rack rails. The connection module is supported within a window formed within the mounting plate, such that a rear portion of the connection module extends away from a rear face of the mounting plate to a first degree, and a front portion of the connection module is approximately flush with the front face of the mounting plate, or at least extends away from the front face of the mounting plate to a second degree, less than the first degree. The mounting plate may be formed of a single piece of flat metal with the front face and the rear face, left/right side edges, and top/bottom edges. First and second ears and locking tabs, may be bent away from edges of the window within the mounting plate to facilitate support for the connection module.

Further scope of applicability of the present invention will become apparent from the detailed description given hereinafter. However, it should be understood that the detailed description and specific examples, while indicating preferred embodiments of the invention, are given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art from this detailed description.

As best seen in FIG. 2, the first and second end caps 23 and 25 of the connection module 27 include first and second blades 115A and 115B at the top 32 of the connection module 27. The first and second end caps 23 and 25 of the connection module 27 also include third and fourth blades 115C and 115D at the bottom 34 of the connection module 27. As shown in FIG. 11, the first, second, third and fourth blades 115A, 115B, 115C and 115D may seat into or pass through the first, second, third and fourth notches 107, 109, 111 and 113, respectively, when the front face of the connection module 27 is placed into the window 73. Alternatively, as shown in FIG. 12, the first, second, third and fourth notches 107, 109, 111 and 113 may be omitted from the mounting plate 51 and the first, second, third and fourth blades 115A, 115B, 115C and 115D may abut against the rear face 55 of the mounting plate 51, adjacent to the first and second longitudinal edges 75 and 77.

FIG. 12 also shows the second element passing through the second through hole 101 being in the form of a screw or bolt. A head of the screw or bolt abuts edges of one of the oval openings 41 of the rail 35. A threaded shank 116 of the screw or bolt passes through the oval opening 41 of the rail 35 and the second through hole 101. A nut 117 is engaged and tightened to the threaded shank 116 and abuts the second locking tab 97.

FIG. 13 shows an alternative embodiment wherein a first threaded insert 119 may optionally be attached within or to the first through hole 95 and replaces the nut 117 of FIG. 12. The first threaded insert 119 may sometimes be called a blind rivet nut, clinch nut or sold under the trademark RIVNUT®. In a preferred embodiment, the first threaded insert 119 may have a thread gauge of M6 and be adapted to engage a correspondingly sized first threaded bolt or screw 121, as shown in FIG. 14. The first threaded bolt or screw 121 would be passed through one of the oval openings 41 of the rail 35 and then tightened into the first threaded insert 119. Of course, an identical second threaded insert would be attached within or to the second through hole 101 and sized to engage with an identical second threaded bolt or screw 123.

FIGS. 13 and 14 also show an optional rigidity enhancement for the mounting plate 51. The top edge 61 of the mounting plate 51 includes a first turned-back extension 125, which extends away from the rear face 55 of the mounting plate 57, at an angle of about sixty to one hundred degrees, to provide rigidity to the top edge 61. Likewise, the bottom edge 63 of the mounting plate 57 includes a second turned-back extension, 127 which extends away from the rear face 55 of the mounting plate 57, at an angle of about sixty to one hundred degrees, to provide rigidity to the bottom edge 63 of the mounting plate 57.

As shown in FIGS. 12 and 14, the connection module 27 securely resides within the window 73. A rear portion of the connection module 27 extends away from the rear face 55 of the mounting plate 51 to a first degree. A front face or portion of the connection 27 module is approximately flush with the front face 53 of the mounting plate 51 or extends away from the front face 53 of the mounting plate 51 to a second degree, less than the first degree.

The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are to be included within the scope of the following claims.
