  • Patent number: 10135169
    Abstract: An electrical connector includes an electrically insulative housing including a front base, a back cover and a floating structure exposed to the outside of an accommodation chamber between the front base and the back cover, and a contact conducting structure including a flexible PC board, multiple conducting terminals electrically connected to respective contacts at the flexible PC board, a support block having fingers respectively extended from respective spring arms thereof for supporting the flexible PC board and spring members supporting the respective fingers. The flexible PC board has slits respectively disposed between each two adjacent contacts so that the conducting terminals can be independently biased with the respective contact without affecting the conducting stability, making the electrical connector practical for high frequency application.

  • Patent number: 7559772
    Abstract: An electrical connector is provided, which includes an insulative housing and a flexible bus inserted into the insulative housing. The insulative housing includes a base defining a slot therein, and a mating portion connected with the base. Mounting portions are integrally formed on opposite sides of the base for receiving fixing sheets. The flexible bus has a top surface and a bottom surface, the bottom surface forming a plurality of contact points on an end thereof. When the flexible bus extends into the slot of the insulative housing, contact points of the flexible bus are exposed out of a side of the mating portion for electrically connecting with a mating connector.

  • Patent number: 7438590
    Abstract: An electrical connector includes an insulative housing receiving a plurality of terminals therein, an upper cover mounted on the insulative housing, a flexible bus, and a casing shielding the upper cover and fixed to the insulative housing. The insulative housing has a mating portion for mating with a mating connector. The flexible bus has a plurality of contacts on an end thereof. The upper cover presses against the flexible bus in assembly, forcing the contacts to contact the terminals. The casing biases against the upper cover, forcing the contacts of the flexible bus to contact the terminals reliably. The flexible bus of the electrical connector does not contact a mating connector directly, thereby lengthening the life of the flexible bus even after repeated plugging.
