Memory Connectors - PC Card Sockets

SF9-STR1-A is a type of PC Card Socket, an electrical connector specifically designed for computer memory cards. It is found in external enclosures and other additional memory devices. The connector fits the PC Card specification for socket dimensions and pin allowances. The PC Card socket is relatively small in size, encloses and provides mechanical and electrical support to the PC cards.

In the case of the SF9-STR1-A, the socket is made of high temperature plastics and silver-plated copper alloy contacts, and features extended spacing between contacts for improved electrical performance. It is designed to fit nearly all digital memory cards, with dimensions of 75.20mm x 50.80mm, receiving pins and contacts measuring 0.32mm H x 0.50mm long.

The PC Card socket consists of a frame which holds 72 spring loaded contacts, which are arranged in two rows along its length. Two parts form the overall socket; the shell or outer portion, and the socket body which houses the spring contact. When the memory card is inserted into the socket, the spring contact deflects and contacts the corresponding pin pads on the card, which provides the electrical connection. Interfacing between the two components results in an electrical flow.

The contact materials used must be carefully selected and designed for reliable electrical connection and data transfer. They should provide corrosion resistance and must satisfy both the insertion and removal forces of the standard PC Card specification. The spring contacts ensure that any external vibration or impact does not lead to a loose electrical connection. The socket body also needs to be designed in a manner which does not interfere with the card’s compliance with the PC Card specification.

Data transfer is achieved by latching the card in the slot with a locking latch. This can either be done manually by inserting and twisting the card, or automatically by a pin or lever mechanism. The lever is usually mounted at the back of the card, preventing it from unexpectedly becoming loose due to a cable pull or other force.

Overall, the SF9-STR1-A PC Card socket is a reliable and efficient connector for use in a variety of applications. It is designed for easy handling and operation, and its fitment and connectivity are reliable. It provides a stable and secure method of interfacing a variety of memory cards, allowing for fast and efficient data transfer.
