Introduction

Card Edge Connectors, also known as edge cards, are a type of electrical interconnection device used to provide power, communication, and other functional needs. They are commonly used in computers and other electronics equipment to connect a card to the motherboard. The physical form of the connection is a plug-in or direct insertion type. The edge of the connector is flared out in 3D, providing more surface area contact as compared to having a flat contact surface. The contacts are arranged in a parallel pattern on both the male and female sides and the contacts are typically made from copper or gold plated contacts.

1703105-1 Application Field and Working Principle

The 1703105-1 is a card edge connector housing made by SAMTEC. It is a mid-mount card edge connector designed for applications where the card edge is mated in a horizontal orientation. The housing is available in right angle, vertical, and horizontal orientations for optimal mating. It is designed to support a wide variety of types of signal applications, such as LVDS, RJ45, USB 3.0, and 7/8 Series.The 1703105-1 features a high temperature thermoplastic construction with PBT-UL 94V-0 compliant material. It has an operating temperature range of -40°C to +105°C and a current rating of 2 to 16 Amps. The housing is available in various pitch sizes and pin count configurations ranging from 2 to 40 pins. The terminal positions are recessed for added strain relief protection and the side pocket design provides additional keying for an improved twist-on locking.

Product Design Advantages

The 1703105-1 brings added benefits to almost any application. Its compact design with minimal wall thickness increases space efficiency while providing superior mechanical performance. The extended lead design improves insertion and retention strength to ensure secure connection with minimal contact with the adjacent board. The pins are made with gold plated contacts which offer excellent conductive properties. The card edges are beveled with rounded corners which improves charge retention during insertion. The side pocket design provides additional positioning and contact protection from shocks and vibrations. The connector housing features a push-in design that allows for easy removal and insertion. It incorporates a latch holder that provides secure latching onto the card edge. It also offers various customizations enabled by the low profile design. The integrated locking mechanism prevents the connector from loosening or coming unplugged while in use.

Conclusion

The 1703105-1 is an ideal card edge connector housing for a wide variety of applications. It offers superior performance, space efficiency, and ease of use in a small form factor. Its design provides increased protection from shocks and vibrations as well as secure latching for a durable and reliable connection. The gold plated contacts and integral locking mechanism ensure a strong and reliable electrical connection. With its high temperature thermoplastic construction, the 1703105-1 ensures greater reliability and longevity in harsh environmental conditions.
