Description

[0001] This application is a divisional application of the application filed by Morales Ltd., filed on August 27, 2019, with application number 201980053767.1 and entitled "Hinged Busbar Assembly". Technical Field

[0002] This disclosure relates to the field of busbars, and more particularly to articulated busbar assemblies. Background Technology

[0003] A slide-in / retractable unit within rack-mounted hardware may require it to be powered on when partially or fully extended. Typically, this involves accessing the storage device, which remains powered and functional, through a storage enclosure that slides out of the chassis (or a portion thereof). Maintaining power to the unit when fully extended typically involves cabling and standard interconnect components used in a slide-track system. Such components would be bulky due to the multiple thick American AWG wires that limit ease of insertion / retraction and their physical size. They also restrict cooling airflow (whether in the open or closed state). Therefore, improvements to the components that maintain power to such units would be appreciated by some.

[0050] Figure 1 The cabinet mounting hardware 20 is shown, which includes a sliding insertable / retractable unit 30. More specifically, Figure 1 and Figure 2 The rack mounting hardware 20 is shown as a 4U rack system with an insertable / retractable upper 2U section. As shown, the sliding insertable / retractable unit 30 can be in the form of a drawer, and the rack mounting hardware 20 can be in the form of a storage cabinet with the drawer installed therein. The sliding insertable / retractable unit 30 has a first component 40 mounted thereon, such as a middle plate, a back plate, a daughter card, etc., and a chassis, while the rack mounting hardware 20 has a second component 50 mounted thereon, such as a middle plate, a back plate, a daughter card, etc., and a chassis.

[0051] The remaining figures illustrate various embodiments of a hinged bus assembly 100, 200, 300, 400, 500, 600, 700, 800, which can be used to connect a first component 40 and a second component 50 together so that power is transmitted between components 40 and 50 and grounding is provided between components 40 and 50. The hinged bus assemblies 100, 200, 300, 400, 500, 600, 700, 800 allow a sliding insertable / removable unit 30 to be pulled outward or pushed inward into the rack-mounted hardware 20 while maintaining an electrical path between the sliding insertable / removable unit 30 and the rack-mounted hardware 20.

[0052] Each embodiment of the articulated bus assembly 100, 200, 300, 400, 500, 600, 700, and 800 includes: a first mounting bus 110, 610 configured to be mechanically and electrically mounted on a first member 40; a second mounting bus 120, 620 configured to be mechanically and electrically mounted on a second member 50; a first extension bus 130, 630 configured to be mechanically and electrically connected to the first mounting bus 110, 610 at a first pivot connection 180; and a second extension bus 140, 640 configured to be mechanically and electrically connected to the second mounting bus 120, 620 at a second pivot connection 182 and configured to be mechanically and electrically connected to the first extension bus 130, 630 at a third pivot connection 184.

[0053] Pay attention to orientation, such as Figures 2 to 7 The diagram shows a first embodiment of the articulated bus assembly 100. The articulated bus assembly 100 includes a first mounting bus 110 and a second mounting bus 120, a first extension bus 130 and a second extension bus 140, three pins 150, three retention clips 160, and six conductive contacts 170. Each conductive contact 170 may be a spring contact. All components of the articulated bus assembly 100, namely the mounting buses 110, 120, extension buses 130, 140, pins 150, retention clips 160, and conductive contacts 170, are conductive, thereby enabling the transmission of electrical energy between components 40 and 50 along the articulated bus assembly 100 and allowing the articulated bus assembly 100 to function as a grounding loop between components 40 and 50.

[0054] Busbars 110 and 120 can be installed in various ways.

[0055] In a first embodiment, the first mounting bus 110 is generally L-shaped and has: a first leg 111, which is fixed to the first member 40 at a fixed connection by suitable means (e.g., bolts, screws, rivets, etc.); and a second leg 112, which extends generally perpendicularly to the first leg 111 and the first member 40. The second leg 112 has a free end 113. A generally cylindrical extension 114 extends outward from an upper or lower portion of the free end 113 (in... Figure 2 In the first mounting bus 110, a generally cylindrical extension 114 extends outward from the lower part of a free end 113. The generally cylindrical extension 114 has an opening (not shown) through which it is disposed, defining an inner wall (not shown) of the generally cylindrical extension 114. The second mounting bus 120 is identical to the first mounting bus 110, so that the same components can be used for either the first mounting bus 110 or the second mounting bus 120. Thus, the second mounting bus 120 has: a first leg 121, which is fixed to the second member 50 at a fixed connection by suitable means (e.g., bolts, screws, rivets, etc.); and a second leg 122, which extends generally perpendicularly to the first leg 121 and the second member 50. The second leg 122 has a free end 123. A generally cylindrical extension 124 extends outward from an upper or lower part of the free end 123 (in Figure 2 In the second mounting bus 120, a generally cylindrical extension 124 extends outward from the upper part of the free end 123. The generally cylindrical extension 124 has an opening 125 through which it is disposed, defining an inner wall 126 of the generally cylindrical extension 124. The first feet 111, 121 of the mounting buses 110, 120 can be modified to connect the mounting buses 110, 120 to a horizontally mounted first member 40, 50 (therefore the mounting bus 110 is not generally L-shaped).

[0056] In such Figure 4 and Figure 5In one of the illustrated second embodiments, the first and / or second mounting busbars 110, 120 have only first feet 111, 121 that secure their respective components 40, 50 at a fixed connection by suitable means, such as bolts, screws, rivets, etc. The first feet 111, 121 are formed as plates. The first feet 111, 121 have a first flat side 111a, 121a and a second flat side 111b, 121b. One of the side surfaces, such as side 111b, 121b, abuts against the respective components 40, 50, so that the first feet 111, 121 and the components 40, 50 are parallel to each other. A generally cylindrical extension 114, 124 extends outward from an edge 111c, 121c of the first feet 111, 121 and outward from the respective components 40, 50. The generally cylindrical extensions 114, 124 have openings 115, 125 through which they are disposed, defining an inner wall of the generally cylindrical extensions 114, 124. In this embodiment, components 40, 50 may be a printed circuit board inserted into an edge card connector on another printed circuit board 42. Although a single extension 114, 124 is shown, multiple extensions 114, 124 may be provided.

[0057] In such Figure 6 and Figure 7 In one of the third embodiments shown, the first and / or second mounting busbars 110, 120 have only first feet 111, 121 fixed to their respective members 40, 50 by suitable means (e.g., bolts, screws, rivets, etc.) at a fixed connection. The first feet 111, 121 are formed as plates. The first feet 111, 121 have a first flat side 111a, 121a and a second flat side 111b, 121b. One of the side surfaces (e.g., side 111b, 121b) abuts against their respective members 40, 50 so that the first feet 111, 121 and members 40, 50 are parallel to each other. A generally cylindrical extension 114, 124 extends outward from a middle portion of the first feet 111, 121 and outward from their respective members 40, 50, which can serve as an intermediate plate or a back plate. The generally cylindrical extensions 114, 124 have openings 115, 125 through which they are disposed, defining an inner wall of the generally cylindrical extensions 114, 124. In this embodiment, members 40, 50 may be edge clips inserted into a printed circuit board 42. Although a single extension 114, 124 is shown, multiple extensions 114, 124 may be provided.

[0058] The first extended busbar 130 is preferably straight in shape and has a first free end 131 and an opposite second free end 132. The sides of the first extended busbar 130 between the two ends 131 and 132 may be flat. A generally cylindrical extension 133 extends outward from an upper or lower portion of the first free end 131, and a generally cylindrical extension 134 extends outward from an upper or lower portion of the second free end 132 (in... Figure 2 In the diagram, generally cylindrical extensions 133 and 134 are shown extending outward from the upper portions of their free ends 131 and 132. Each of the generally cylindrical extensions 133 and 134 has an opening 135 and 136 respectively passing through it, the openings 135 and 136 defining an inner wall 137 and 138 of the generally cylindrical extension 133 and 134. The generally cylindrical extension 133 is positioned relative to the generally cylindrical extension 114 of the first mounting busbar 110 such that their openings are aligned with each other. Figure 2 As shown, the generally cylindrical extension 133 is located above the generally cylindrical extension 114.

[0059] The second extended busbar 140 is identical to the first extended busbar 130, thus the same components can be used for either the first extended busbar 130 or the second extended busbar 140. Therefore, the second extended busbar 140 has a first free end 141 and an opposite second free end 142. The sides of the second extended busbar 140 between the two ends 141 and 142 may be flat. A generally cylindrical extension 143 extends outward from an upper or lower portion of the first free end 141, and a generally cylindrical extension 144 extends outward from an upper or lower portion of the second free end 142 (in...). Figure 2 In the diagram, generally cylindrical extensions 143 and 144 are shown extending outward from the lower portions of free ends 141 and 142. Each of the generally cylindrical extensions 143 and 144 has an opening (not shown) passing through it, defining an inner wall (not shown) of the generally cylindrical extensions 143 and 144. The generally cylindrical extensions 143 are positioned relative to the generally cylindrical extensions 134 of the first extension busbar 130 such that their openings are aligned with each other. Figure 2 As shown, the generally cylindrical extension 143 is located below the generally cylindrical extension 134. The generally cylindrical extension 144 is positioned relative to the generally cylindrical extension 124 of the second mounting busbar 120 such that their openings are aligned with each other. Figure 2 As shown, the generally cylindrical extension 144 is located below the generally cylindrical extension 124.

[0060] Each cylindrical extension 114, 124, 133, 134, 143, 144 has a conductive contact 170 fixed to its respective inner wall within its respective opening. The conductive contact 170 may have any suitable construction, but is preferably of the type shown and described in the applicant's international publication number WO2018 / 093981, the contents of which are incorporated herein by reference in their entirety.

[0061] The first connection 180 is formed by inserting one of the pins 150 into aligned openings and conductive contacts 170 in the cylindrical extensions 114 and 133 of the first mounting bus 110 and the first extension bus 130, respectively, and securing them in place with one of the retaining clips 160, thereby connecting the first mounting bus 110 and the first extension bus 130 not only mechanically but also electrically. The second connection 182 is formed by inserting a second pin 150 therein into aligned openings and conductive contacts 170 in the cylindrical extensions 124 and 144 of the second mounting bus 120 and the second extension bus 140, respectively, and securing them in place with a second retaining clip 160 therein, thereby connecting the second mounting bus 120 and the second extension bus 140 not only mechanically but also electrically. The third connecting portion 184 is formed by inserting a third pin 150 therein into aligned openings and conductive contacts 170 in the cylindrical extensions 134 and 143 passing through the first extension bus 130 and the second extension bus 140, respectively, and securing them in place with a third retaining clip 160 therein, thereby connecting the first extension bus 130 and the second extension bus 140 not only mechanically but also electrically. The first connecting portion 180, the second connecting portion 182, and the third connecting portion 184 thus act like hinges, so that both the first extension bus 130 and the second extension bus 140 can rotate and remain electrically connected.

[0062] Figures 8 to 10 A pair of articulated bus assemblies 100 are shown positioned adjacent to each other within rack mounting hardware 20, with a sliding insertable / retractable unit 30 movable within the rack mounting hardware 20 and still electrically connected when fully extended. A first component 40 is mounted on the sliding insertable / retractable unit 30, while a second component 50 is mounted on the rack mounting hardware 20. One of the pair of articulated bus assemblies 100 is shown as... Figure 3 and Figure 4 As shown in the diagram, one of the pair of articulated bus assemblies 100 is in a 180-degree flip configuration, such that the rotation of the first extended bus 130 and the second extended bus 140 occurs in opposite directions. The pair of articulated bus assemblies 100 pivot about the connecting portions 180, 182, and 184. Figures 8 to 10As shown, due to the orientation of the pair of articulated bus assemblies 100 mounted between the sliding insertable / retractable unit 30 and the rack mounting hardware 20, the pair of articulated bus assemblies 100 pivot in a scissor-like configuration. In one embodiment, one articulated bus assembly 100 transmits power (such as 12 volts DC) between the first member 40 and the second member 50, while the other articulated bus assembly 100 serves as a grounding loop between the first member 40 and the second member 50.

[0063] Figure 11 A second embodiment of the articulated bus assembly 200 is shown. The articulated bus assembly 200 is identical to the articulated bus assembly 100, except that the first extended bus 130 and the second extended bus 140 respectively include embossings 239 and 249. The embossings 239 and 249 are added along the length of the first extended bus 130 and the second extended bus 140 to the sides of the extended bus 130 and 140 to improve the rigidity of the extended bus 130 and 140. In the illustrated embodiment, each embossing 239 and 249 is straight and extends from near the first end 131 and 141 to near their respective second ends 132 and 142. The embossings 239 and 249 can take various shapes (e.g., but not limited to a curve, a corrugated shape, a serrated shape, etc.) and do not need to have the same shape. Furthermore, the embossings 239 and 249 can form multiple overlapping embossings along the length of the extended bus 130 and 140. For example, but not limited to, an upper embossing extends from near the first ends 131, 141 to just past the midpoint of the extended busbars 130, 140, while a lower embossing extends from near the second ends 132, 142 to just past the midpoint of the extended busbars 130, 140.

[0064] Figure 12A third embodiment of a hinged bus assembly 300 is shown. The hinged bus assembly 300 includes a pair of identical hinged bus assemblies 100 positioned adjacent to each other (e.g., one directly above the other). Although shown as a top bus assembly 100 and a bottom bus assembly 100, the pair of bus assemblies 100 may be side-by-side. Each hinged bus assembly 100 is connected at its first end to a first member 40 and at its second end to a second member 50. The pair of hinged bus assemblies 100 are spaced apart from each other, such that a space is formed between the pair of hinged bus assemblies 100 along their length. Each hinged bus assembly 100 provides its own conductive path between the first member 40 and the second member 50. The hinged bus assembly 300 also includes a pair of insulating fasteners 390 that hold the pair of hinged bus assemblies 100 together in position, thereby ensuring that the pair of hinged bus assemblies 100 rotate together. A first fixing device 390 generally surrounds two first extended busbars 130 to positionally secure the two first extended busbars 130 together, and a second fixing device 390 generally surrounds two second extended busbars 140 to positionally secure the two second extended busbars 140 together, thereby ensuring that each hinged busbar assembly 100 rotates together. The fixing device 390 may be a strip, strap, etc. Each fixing device 390 may be generally O-shaped and positioned around its respective two extended busbars 130, 140.

[0065] Figure 13 The articulated bus assembly 300 is shown positioned within rack mounting hardware 20 such that a sliding insertable / retractable unit 30 is movable within rack mounting hardware 20 while remaining powered when fully extended. A first component 40 is mounted on the sliding insertable / retractable unit 30, while a second component 50 is mounted on rack mounting hardware 20. Although only one articulated bus assembly 300 is shown... Figure 10 However, it will be understood that more articulated bus assemblies 300 may be used as needed / required. In one embodiment, one articulated bus assembly 100 of the articulated bus assembly 300 transmits power (such as 12 volts DC) between the first member 40 and the second member 50, while another articulated bus assembly 100 of the articulated bus assembly 300 serves as a grounding loop between the first member 40 and the second member 50.

Although shown as top and bottom bus assemblies 200, the two bus assemblies 200 may be side-by-side. Each hinged bus assembly 200 is connected at its first end to a first member 40 and at its second end to a second member 50. The pair of hinged bus assemblies 200 are spaced apart from each other, thereby forming a space along the length of the pair of hinged bus assemblies 200 between them. Each hinged bus assembly 200 provides its own conductive path between the first member 40 and the second member 50. The hinged bus assembly 400 then further includes a pair of insulating fasteners 490 that hold the pair of hinged bus assemblies 200 together in position, thereby ensuring that the pair of hinged bus assemblies 200 rotate together.

The second leg 612 has a free end 613. A generally cylindrical extension 614 extends outward from the middle of the free end 613. The generally cylindrical extension 614 has an opening (not shown) through it, the opening defining an inner wall (not shown) of the generally cylindrical extension 614. The second mounting bus 620 is generally L-shaped and has: a first leg 621, which is fixed to the second member 50 at a fixed connection by suitable means (e.g., bolts, screws, rivets, etc.); and a second leg 622, which extends generally perpendicular to the first leg 621. The second foot 622 has a free end 623. A first generally cylindrical extension 624a and a second generally cylindrical extension 624b extend outward from the upper and lower parts of the free end 623, respectively. Each generally cylindrical extension 624a and 624b has an opening (not shown) through which an inner wall (not shown) defining the generally cylindrical extension 624a and 624b is disposed.

[0071] Alternatively, busbars 610 and 620 can be installed using... Figures 4 to 7 As shown in the figure.

[0072] The first extended busbar 630 is generally straight in shape and has a first free end 631 and an opposite second free end 632. The side of the first extended busbar 630 between the two ends 631 and 632 may be flat or may have features such as... Figure 11 The embossing is shown. A first generally cylindrical extension 633a and a second generally cylindrical extension 633b extend outward from the upper and lower portions of the free end 631, respectively, while generally cylindrical extensions 634a and 634b extend outward from the upper and lower portions of the second free end 632, respectively. Each generally cylindrical extension 633a, 633b, 634a, and 634b has an opening (not shown) through which it is disposed, defining an inner wall (not shown) of the generally cylindrical extension 633a, 633b, 634a, and 634b. A generally cylindrical extension 614 of the first mounting busbar 610 is located between the generally cylindrical extensions 633a and 633b of the first extending busbar 630 so that their openings are aligned with each other.

[0073] The second extended busbar 640 has a first free end 641 and an opposite second free end 642. The side of the second extended busbar 640 between the two ends 641, 642 may be flat or may have features such as... Figure 11The embossing is shown. A generally cylindrical extension 643 extends outward from a middle portion of a first free end 641, and a generally cylindrical extension 644 extends outward from a middle portion of a second free end 642. Each generally cylindrical extension 643, 644 has an opening (not shown) through which it is disposed, defining an inner wall (not shown) of the generally cylindrical extension 643, 644. The generally cylindrical extension 643 of the second extension bus 640 is located between the generally cylindrical extensions 634a, 634b of the first extension bus 630 so that their openings are aligned with each other. The generally cylindrical extension 644 of the second extension bus 640 is located between the generally cylindrical extensions 624a, 624b of the second mounting bus 620 so that their openings are aligned with each other.

[0074] Each cylindrical extension 624a, 624b, 633a, 633b, 634a, 634b has one conductive contact 170 fixed to its respective inner wall within its respective opening. Each cylindrical extension 614, 643, 644 has a pair of conductive contacts 170 fixed to its respective inner wall within its respective opening. The use of a pair of conductive contacts 170 relative to a single conductive contact within each cylindrical extension 614, 643, 644 allows for high current performance.

[0075] The first connection 180 is formed by inserting one of the pins 150 into aligned openings and conductive contacts 170 in the cylindrical extensions 614, 633a, 633b passing through the first mounting bus 610 and the first extension bus 630, and securing them in place by one of the retaining clips 160, thereby connecting the first mounting bus 610 and the first extension bus 630 not only mechanically but also electrically. It will be understood that the cylindrical extensions 633a, 633b may instead extend from the first mounting bus 610 and the cylindrical extension 614 may instead extend from the first extension bus 630 to form the first connection 180. The second connection 182 is formed by inserting a second pin 150 therein into aligned openings and conductive contacts 170 of cylindrical extensions 624a, 624b, 644 passing through the second mounting bus 620 and the second extension bus 640, and securing them in place by one of the retaining clips 160, thereby connecting the second mounting bus 620 and the second extension bus 640 not only mechanically but also electrically. It will be understood that the cylindrical extensions 624a, 624b may alternatively extend from the second extension bus 640 and the cylindrical extension 644 may alternatively extend from the second mounting bus 620 to form the second connection 182.

[0076] The third connection 184 is formed by inserting a third pin 150 therein into aligned openings and conductive contacts 170 of cylindrical extensions 634a, 634b, 643 passing through the first extension bus 630 and the second extension bus 640, and securing them in place by one of the retaining clips 160. This connection mechanically and electrically connects the first extension bus 630 and the second extension bus 640 at the third connection 184. It will be understood that the cylindrical extensions 634a, 634b may alternatively extend from the second extension bus 640, and the cylindrical extension 643 may alternatively extend from the first extension bus 630 to form the third connection 184. The first connection 180, the second connection 182, and the third connection 184 thus act like hinges, allowing both the first extension bus 630 and the second extension bus 640 to rotate while maintaining an electrical connection.

[0077] Figure 18 A seventh embodiment of the articulated bus assembly 700 is shown. The articulated bus assembly 700 is identical to the articulated bus assembly 600 except for the provision of a pair of first extension buses 630 and a pair of second extension buses 640 (and associated / required pins 150, retaining clips 160, and conductive contacts 170).

The connecting parts 180, 182, 184, 186, and 188 thus act like hinges, allowing both the first extended bus 630 and the second extended bus 640 to rotate and maintain a constant electrical connection. It will be understood that... Figures 2 to 17 The embodiments may also have multiple extended buses.

[0078] Figure 19 The articulated bus assembly 700 is shown in a horizontal position. As the articulated bus assembly 700 pivots about pivot connections 180, 182, 184, 186, and 188, the articulated bus assembly 700 folds up. Although Figures 2 to 18 The diagram shows each articulated busbar assembly 100, 200, 300, 400, 500, 600, and 700 in a vertical position.

[0080] Each fixing device 890 is insulated and secures the two hinged bus assemblies 100 together in position, thereby ensuring that the two hinged bus assemblies 100 rotate together. Each fixing device 890 is positioned within the space between the two bus assemblies 100 to secure the two bus assemblies 100 together in position, thereby ensuring that the two hinged bus assemblies 200 will rotate together. Each fixing device 890 is generally H-shaped and has: a crossbar 894 extending through the space between the two extending busbars 130; a first portion 896 extending from a first end of the crossbar 894; and a second portion 898 extending from a second end opposite to the crossbar 894.

A cable 892 extends through each central channel 900 and also through a recess 904 on each extension busbar 130, 140 near the end of a fixing device 890. Thus, in this embodiment, the cable 892 "snails" through the hinged busbar assembly 800, such that the cable 892 passes through busbar 130 along one side of the hinged busbar assembly 800 and subsequently through busbar 140 along the opposite side of the hinged busbar assembly 800. In another embodiment, all of the multiple fixing devices 890 are oriented in the same direction, such that the first portion 896 of the fixing device 890 provided on the extension busbar 130 is adjacent to the first portion 896 of the fixing device 890 provided on the extension busbar 140, and the second portion 898 of the fixing device 890 provided on the extension busbar 130 is adjacent to the second portion 898 of the fixing device 890 provided on the extension busbar 140. The cable 892 extends along the same side of the hinged busbar assembly 800 through each central channel 900. In this embodiment, the recess 904 can be eliminated.

The ends of the cable 892 can be suitably connected to the printed circuit boards 906, 908 at the connectors. It will be understood that although a single cable 892 and its connector and a printed circuit board 906, 908 at each end are provided, multiple cables 892, multiple connectors, and associated printed circuit boards 906, 908 can be routed through the central channel 900 of multiple fixtures 890 to provide additional, accommodated electrical transmission capabilities.
