Card Edge Connectors - Housings

Card edge connectors are widely used in various industrial, computer and telecommunication applications. The most common application for card edge connectors is in personal computers where it is used to connect internal circuit boards and cards. The second most common use of card edge connectors is in telecommunication systems for connecting peripheral devices such as modems and routers.In general, card edge connectors are typically made of plastic housings with metal contacts on the edge. The housing contains two contact plates, one containing the contacts and the other containing the pins. The pins and contacts are made of metal and can be either straight or bent. The contacts are typically crimped onto the contact plate.Card edge connectors come in two basic types: open frame and closed frame. Open frame card edge connectors use a single slot on the edge of the card, while closed frame card edge connectors have multiple slots, each with a separate slot for pins. The open frame connectors are the most common type of card edge connectors and are used in most personal computer applications.The working principle of card edge connectors is based on the attractive force between the contacts and the pins. When two objects with different electric potentials are connected, an electromotive force (EMF) is generated and this is called an attractive force. The EMF generates an interaction between the contacts and the pins, which is responsible for making an electrical connection. The EMF is also responsible for loosening the connections between contacts and pins when the card is removed, hence the card edge connectors must be designed for easy removal. In order to loosen the connection, a sliding mechanism is used to force the connecting pins away from the contacts. When the card is inserted again, the force of the EMF draws the pins back into contact with the contacts.There are several other design features that improve the connection and make it more secure. Contacts may be spring-loaded to ensure that there is a constant contact pressure between the contacts and pins. In addition, there may be a mechanism for retention and alignment of the contacts and pins. This may include hooks or ridges to prevent the contacts from moving out of place when the card is inserted.In conclusion, card edge connectors are widely used in various industrial, computer and telecommunication applications. These connectors are typically made of plastic housings with metal contacts on the edges and pins on the other side. The working principle of card edge connectors is based on the attractive force between the contacts and the pins. Various design features are employed to increase the security and reliability of the connection.
