What is a Card Edge Connector? What are the main types of Card Edge Connectors functions and characteristic features electrical performance parameters?

Card edge connector is a kind of mechanical connector, which can connect the electrical signal transmission equipment and connector interface through the way of card edge. The main features of the card edge connector is easy to plug and unplug, reliable contact, reusable, with anti-jitter, anti-wrong plugging and other functions. The following is an introduction to the main types of card edge connectors, functions and features, as well as electrical performance parameters. Main types (1) circular card edge connector: circular card edge connector is usually used for power and signal transmission, with waterproof, dustproof and other functions. Common circular card edge connectors are MIL-C-5015 and MIL-C-26482, etc. (2) Rectangular connectors: Rectangular connectors are usually used for data transmission and communication, such as aerospace, military, railroad and so on. Common rectangular card-edge connectors include DIN41622, DIN41618, DIN41612, etc. (3) Oval snap-edge connectors: Oval snap-edge connectors are commonly used in the field of rolling stock and aircraft. Common oval card edge connectors are VG95234, VG95328, etc. Functions and features (1) Card edge connectors can realize easy plugging and unplugging, reliable contact, anti-jitter, anti-wrong plugging and other functions, thus ensuring the stability and reliability of the transmission equipment and connector interface. (2) The card edge connector usually adopts metal shell and insulating material, which can provide waterproof, dustproof and other protective functions, suitable for use in harsh environments. (3) Card edge connectors can realize rapid connection and disassembly, with reusable characteristics, can save time and cost, improve productivity. (4) Card edge connectors can adapt to different working voltage, current and frequency, with high versatility, can be applied to a variety of electrical signal transmission equipment. Electrical performance parameters (1) Rated voltage: the rated voltage of the card edge connector refers to the greater voltage that the connector can withstand under normal operating conditions. (2) Rated current: the rated current of the card edge connector refers to the connector can withstand under normal operating conditions of the greater current. (3) Insulation resistance: card edge connector insulation resistance refers to the connector internal insulation material under normal operating conditions can withstand greater resistance.
