摘要

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.

Connecting the coaxial cables 104, 106, 108 and the end of the drain wire 114 in this manner eliminates the need to use a jumper wire to individually ground each coaxial cable shield to the BGA 404 simplifying the connection and increasing the yields and manufacturability of the entire system. In addition, the termination length required to connect the coaxial cables 104, 106, 108 to the BGA 404 may be reduced compared to existing termination methods utilizing jumper wires while also allowing for a reduction in an overall outer diameter of the cable assembly 100. For example, a camera 402 used in medical procedures may be limited to having a maximum outer diameter of the cable assembly less than 2 millimeters. Other applications may have even stricter requirements such that the diameter of the cable assembly 100 must be less than about 1 millimeter. Having a smaller diameter may allow the cable assembly 100 to be used in additional applications that require a small form longitudinal or horizontal termination factor but still require the ability to transmit multiple power or signals over any bandwidth or attenuation.
