Patent
Fci | Date: 2012-05-09

Lightweight, low cost, high density electrical connectors are disclosed that provide impedance controlled, high-speed, low interference communications, even in the absence of shields between the contacts, and that provide for low insertion loss. Signal contacts (S) and ground contacts (G) within the connectors can be scaled and positioned relative to one another such that a differential signal in a first differential pair produces a high field (H) in the gap between the contacts that form the signal pair a low field (L) near an adjacent signal pair.

A high speed flexible printed circuit (FPC) connector includes a housing with ground and signal contact terminal pairs arranged in the housing in a staggered manner along a lateral direction. The housing has a cavity for receiving an FPC board therein. Each ground contact terminal has an upper arm positioned adjacent to a top wall of the cavity and a lower arm positioned adjacent to a bottom wall of the cavity. Each signal contact terminal has only a lower arm positioned adjacent to the bottom wall of the cavity. Signal contact terminals with the only lower arm provide the connector with better signal integrity. An actuator is coupled to the housing for fixing the FPC board in the cavity to establish electrical connections. The actuator has recesses corresponding to the positions of the signal pairs to provide a dielectric constant different from that of the other parts of the actuator.

Disclosed are electrical connectors and methods of assembling an electrical connector having standard (i.e., with electrical contacts having in-line tails), jogged (i.e., with electrical contacts having jogged tails but not connected orthogonally to another connector through a substrate), and/or orthogonal (i.e., with electrical contacts having jogged tails that are used in an orthogonal application) leadframe assemblies in the same connector. This provides the flexibility of using some of the available contacts in an orthogonal application and, at the same time, having remaining contacts available for routing on the midplane PCB.; Though this could be done using only orthogonal leadframe assemblies, the combination of standard leadframe assemblies with orthogonal leadframe assemblies creates additional spacing between the PCB vias, so that signal traces can be more easily routed on the midplane PCB.


An optical cable assembly is provided, an optical cable provided with one or more optical fibers, a strain-relieve device mounted on the optical cable and configured to provide a strain relieve when the optical cable is fed into an optical module through an opening in a housing of the optical module, wherein the strain-relieve device is provided with an adjustment mechanism configured to adjust a distance between an end portion of the one or more optical fibers and the strain-relieve device. Furthermore, an optical module and a method for assembling an optical cable assembly are provided.
