Abstract
A single large flexible rigid (or rigid flex) or a number of smaller flexible rigid PCBs replace the cabling in a data cabinet. The PCBs may include a main limb section 1, small and large arms 3, 4, and appropriate connectors 2, 5, 6. The PCBs may be used with single or double row servers. The use of flexible rigid PCBs may permit quicker and easier installation of servers in cabinets.
Description
Description
Title: -Network Server Flexi. Circuit
Introduction & Background to thc invcntion
The invention is used in the Data communications industry and simplifies the installation of data cabinets.
The invention requires the ability to design and construct Flex rigid circuits several metres long. Traditional non rigid flex circuits do not withstand the rigours of this marketplace.
The invention relates to network server cabinet/cabinets that invariably contain a vast number of blades, switches, interconnections and a large array of bulky high speed cables. This can require several thousand interconnections and the network server cabinets can be several metres high.
The sheer number and volume is very difficult to install, manage, maintain and ensure correct interconnectivity. Due to the large number of connections the network servers a prone to mechanical failure primarily due to the mass and weight of the cables. There are also significant variations in data rates and EMC immunity.
Previously a limit of 1 M length maximum for a rigid flexi circuit excluded there use in such applications. Our invention removes this limitation, using newly available materials and processes.
The invention replaces all or most of the interconnecting cables with either a single large Flex. Rigid PCB or a number of smaller format flex rigid PCB's. The selection of either solution is entirely at the discretion of the user. This allows maximum flexibility to the configuration.
Introduction to the drawings
A typical single row Flexi is shown in FIG: 1 & FIG: 2 and double row Flexi in FIG: 4 & FIG: 5
Brief description of Items on drawings: -
1. Main flexible limb section.
2. Inlet and out let female RJ45 connectors.
3. Small arm, rigid PCB section.
4. Large arm, rigid PCB section.
5. RJ45 flexible limb section.
6. Male PCB mount RJ45 connectors.
Detailed description of the invention
The invention creates a single circuit board several meters in length that can replace thousands of standard cable interconnections within a data cabinet. This reduces installation time down from days to hours. The key aspect of the invention is that by using a flex-rigid construction virtually all problems of shock and vibration are removed.
The construction process allows for various lengths and styles of switches to be connected together via the flex rigid limbs Figi: -Denotes flexi to suit single row server, (in 2D).
Fig 2: -Denotes flexi to suit single row server, (in 3D) Fig 3: -Denotes Flexi to suit single row server, (shown laid flat) Fig 4: -Denotes flexi to suit double row server, (in 2D).
Fig 5: -Denotes flexi to suit double row server, (in 3D)
Brief description of Items on drawings: -
1. Main flexible limb section.
2. Inlet and out let female RJ45 connectors.
3. Small arm, rigid PCB section.
4. Large arm, rigid PCB section.
5. RJ45 flexible limb section.
6. Male PCB mount RJ45 connectors.
Possible modifications & Variations As most Data communication cabinets are unique to each system design, the use of long or short, single or double limbs offers maximum flexibility in design and utilisation.
Advantaes of the invention The time required for a typical installation of a network server can be reduced from days to hours.
The Flexi solution is considerably lighter in weight and mass.
The Flexi solution installation process is significantly simpler and quicker and there for less expensive.
The Flexi solution produces a consistent and stable data rate transfers.
The Flexi solution produces a consistent and stable EMC/EMI performance.
The Flexi solution allows for several characteristic impedances to be specified within the same assembly.
The Flexi solution gives superior resilience to mechanical shock and vibration.
The Flexi solution eliminates the possibility of incorrect insertion of connectors.
