Abstract
Methods and apparatus for a shielded and grounded cable assembly include a coaxial cable assembly having a uniform spacing between cables to pre-align the cable assembly in an array corresponding to a connection layout of at a source end. The cable assembly includes a plurality of coaxial cables with exposed shields that are commonly grounded to a drain wire. The cable assembly may also be configured to be connected vertically/perpendicularly to a ball grid array or edge connected to a circuit board.
Claims21
A cable assembly for connecting to a source device having a connection layout including a ground connection, comprising:
- an outer jacket;
- a first and a second coaxial cable disposed within the outer jacket, wherein:
- each coaxial cable comprises an exposed shield;
- and
- the exposed shield of the first coaxial cable is in contact with the exposed shield of the second coaxial cable;
- and
- a single drain wire disposed within the outer jacket coextensively with the first and second coaxial cables, wherein the drain wire is in contact with the exposed shield of at least one of the first and second coaxial cables, wherein
- the first and second coaxial cables and the drain wire are arranged in an array configured to pre-align the first and second coaxial cables and the drain wire to the connection layout of the source device to allow the drain wire to connect to the ground connection on the source device and act as a common ground for the first and second coaxial cables.
An internally shielded cable assembly for connecting to a source device having a connection layout including a ground connection, comprising:
- an outer jacket having an internal volume;
- a plurality of coaxial cables disposed within the internal volume of the outer jacket, wherein:
- each coaxial cable of the plurality of coaxial cables comprises an exposed outer shield extending along an entire length of the cable assembly;
- the exposed outer shield each coaxial cable of the plurality of coaxial cables is in contact with at least one outer shield of another cable of the plurality of coaxial cables;
- and
- a drain wire disposed within the internal volume of the outer jacket coextensively with the plurality of coaxial cables, wherein the drain wire is in contact with the exposed outer shield of at least one of the plurality of coaxial cables, and wherein:
- the plurality of coaxial cables and the drain wire are arranged in an array having an orientation configured to pre-align the plurality of coaxial cables and the drain wire to the connection layout of the source device to allow the drain wire to connect to the ground connection on the source device and act as a common ground for the plurality of coaxial cables.
A method of forming an internally shielded cable assembly for connecting to a source device having a connection layout including a ground connection, comprising:
- arranging a plurality of coaxial cables and a single drain wire in an array configured to pre-align the plurality of coaxial cables and the drain wire to the connection layout of the source device to allow the drain wire to connect to the ground connection on the source device, wherein:
- each coaxial cable comprises an exposed shield;
- the exposed shield of a first coaxial cable from the plurality is in contact with the exposed shield of a second coaxial cable from the plurality;
- and the drain wire is in contact with the exposed shield of at least one of the plurality of coaxial cables and acts as a common ground for the plurality of coaxial cables:
- and enclosing the plurality of coaxial cables and the drain wire within an outer jacket.
