Rectangular Connectors - Accessories

Rectangular connectors and accessories are devices used to connect different electrical components on a board. The 172857-1 connector is a device used to make multi-pole connections, where a wire runs from the connector pin to its opposite connection point. Its common application is to provide control of signal and power distribution in printed circuit boards. This article provides an overview of the 172857-1 connector and its working principle.

Application Field

The 172857-1 connector is a necessary accessory used in many applications, including automotive and electrical power devices, such as electrical engine control systems. The connector is composed of two parts, a male and a female, with spring-contact for the wires mounted inside the male part. The connector’s construction allows for insulation between wires, as well as superior electrical performance due to its rib-shaped locking key. The connector has three current-carrying (I/O) signal contacts, as well as one ground contact that can accept wire strands from 18 gauge to 12 gauge.

The 172857-1 connector is designed for operating temperatures ranging from -40 to +125°C and is used in applications requiring a high degree of corrosion resistance. It is suitable for applications requiring high signal integrity, and features a dust-proof and waterproof construction. The connector is also readily available in a wide variety of configurations, including single-pole to 4-pole for various signal types.

Working Principle

The working principle of the 172857-1 connector is based on the connection between wires and contact pins. Two parts, one female and one male, are connected by locking the two parts together. The connector is designed so that the user can easily make a reliable connection, using only a few simple steps. The first two steps are to slightly unscrew the locking knob located at the bottom of the male connector, and to insert the wires into the slot on the side of the female connector.

The next step is to partially slide the male connector towards the female connector until the two spring-loaded contact elements meet. At this stage, the user can tighten the locking knob until the two parts are firmly connected and the wires are secure. To remove the connector, the user should unscrew the locking knob and then slightly push against the two parts until they are separated.

The 172857-1 connector is also designed so that the user can easily adjust the characteristic impedance of the wires without any modifications. This is done by adjusting the wire length until the desired impedance is achieved. This connector improves signal performance and is suitable for applications that require high speed and robust performance.

Conclusion

In conclusion, the 172857-1 connector is an extensively used device in a wide variety of applications, from automotive to electrical power systems. It is designed for superior performance in demanding environments, and has a robust construction with rib-shaped locking keys that enable secure connection of signal and power cables. The connector also has adjustable characteristic impedance, and can be easily connected and disconnected using a simple locking knob. It is an ideal choice for applications that require high speed and robust performance.
