Rectangular connectors, such as the HTSW-225-16-L-Q-RA, are used in a variety of applications due to their strength, consistency, and smaller footprint. Rectangular connectors come in several forms such as headers, male pins, and board-to-board connectors. This article will explore the application fields and working principle of the HTSW-225-16-L-Q-RA and the various types of rectangular connectors.

The HTSW-225-16-L-Q-RA is a header-style rectangular connector used to terminate and pass electrical signals between two printed circuit boards. It has a 1 row by 16 pin configuration and a vertical polarized design which is ideal for applications where the boards must be closely stacked together or soldered directly to a host device. The contact pins are precision-stamped from copper alloy, while the insulator housing is molded from UL94V-0 rated thermoplastic which provides high strength, stability, and insulation protection. The header is designed to mate with 20-22 AWG wires which is ideal for applications that require a low-profile and vibration resistant connection.

Headers are generally used in mobile applications, where their compact size and durable construction make them a favorable choice. In addition, headers can also be used in industrial and automotive applications, wherein their tight connection design can help to reduce interference and protect wires and components from physical damage or environmental hazards. Headers can be used in all types of circuits, from high frequency/voltage to low frequency/voltage, and being highly customizable, they make excellent solutions for many device and engineering needs.

Male pins are the second type of rectangular connector and also come in the form of headers. Male pins are designed to be inserted into the female segment of a printed circuit board and are used mainly for creating an electrical connection between two components or devices. Male pins are typically made from a copper alloy and are precision-formed to eliminate electrical noise and reduce the risk of short circuits. The downside of male pins is that they are not as robust as headers, but they are more cost effective and provide a reliable connection that can handle high-frequency signals.

The third type of rectangular connector is the board-to-board connector. These connectors are typically used in applications where boards must be connected in a regulated fashion, such as the interconnect between a CPU and memory system. Board-to-board connectors generally have a higher pin density than other types of connectors given their close fit between the printed circuit boards. Board-to-board connectors typically require guide pins to ensure correct mating and can also incorporate protective features such as shielding or contact hold-down clips. These connectors come in a variety of sizes and formats to cover most application needs.

The working principle of the HTSW-225-16-L-Q-RA is relatively straightforward. After being plugged into its mate, the contact pins of the male header make contact with their corresponding female terminal in the female segment and establish a connection. The connection between the male and female halves is made secure by the internal insulation housing which protects the pins from external wear and tear, and by the contact-pin retaining mechanism which prevents the pins from pulling out. The UL94V-0 rated thermoplastic insulator housing also serves to ensure that the connection remains temperature-stable and reliable for long-term use.

In conclusion, the HTSW-225-16-L-Q-RA is a header-style rectangular connector ideal for providing secure and robust electrical connections between two printed circuit boards. Its design makes it suitable for numerous applications, ranging from mobile and automotive to industrial and medical. At the same time, all types of rectangular connectors offer reliable connectivity and come in a variety of sizes and formats to meet different requirements. By understanding the application fields and working principles of each type of rectangular connectors, users can make the right choice for their specific needs.
