SMK Product Introduction: Edge Connector

SMK’s Changes in Automotive Edge Connectors

Board-to-wire connectors used for inter-unit and board-to-board connections have been replaced by edge-mount connectors. By replacing these connectors, the height of the connectors on the board can be reduced from 15mm to a maximum of 5mm, thereby lowering the overall equipment height and reducing the overall weight by minimizing the number of connectors.

Example of use:

Connections within the secondary battery module, connections between ECUs, and vehicle light connections.

SMK product advantages:

• The W-type contact structure provides high reliability.
• Contact shape considering vibration following

Card edge connectors , widely known in the market as gold finger slot connectors or card edge connectors, are relatively inexpensive to manufacture. These connectors are commonly used in personal computers, 3C peripherals, the energy sector, traffic control systems, transportation systems, inter-system device connections, and medical devices. They provide simple and fast data transmission, and because they are a single-sided solution, they are relatively inexpensive while still offering good performance.

The product is widely used in:

1. Personal computers : Card edge connectors are commonly used in personal computers, for example, to connect graphics cards, memory modules and other expansion cards.
2. Energy sector : Card edge connectors are also used in the energy sector, such as solar energy systems, wind energy systems, and power equipment.
3. Traffic control systems : Card edge connectors are used in traffic lights, streetlights and other traffic control equipment.
4. Transportation systems : such as control systems and equipment in trains, subways, and buses.
5. Medical devices : Card edge connectors are also widely used in medical devices, such as medical imaging equipment, monitoring equipment and surgical equipment.

Characteristic:

1. Durability and robustness : The design of the edge connector allows it to withstand frequent mating operations and maintain stability during prolonged use. This makes it ideal for applications requiring reliable connections.
2. Low cost : Because the edge connector is only one side, its manufacturing cost is relatively low. This makes it an option for projects with limited budgets.
3. Simple and high-speed data transmission : The card edge connector provides simple and high-speed data transmission, making it particularly suitable for personal computers and other applications that require fast connectivity.
4. Wide range of applications : Card edge connectors are not only used in personal computers, but also in the energy sector, traffic control systems, transportation systems, and medical equipment. This makes them an ideal choice for many industries.
