  • Patent number: 9466903
    Abstract: 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.

  • Publication number: 20150171536
    Abstract: An electrical connector for connecting to a flexible/flat circuit board includes a housing having a cavity, contacts disposed in the cavity of the housing, and a metal shield mounted to the housing. Locking members are attached to the housing and having resilient locking projections disposed in the cavity. When a flexible/flat circuit is inserted into the cavity, openings/notches formed on the flexible/flat circuit are engaged with the locking projections such that the flexible/flat circuit is secured to the housing. The shield is rotatable relative to the housing and engaging to the locking members. When at an open position, the shield presses against the locking members to deflect and push the locking projections away from the cavity such that the flexible/flat circuit is disengaged from the locking projections and can be detached from the connector.
