HTSW-138-21-S-D

Introduction

HTSW-138-21-S-D, commonly known as a mini-pin connector, is a rectangular-shaped connector used for signal transfer in a variety of applications. It is composed of high-conductive stainless steel or copper pins, gold plated contacts, and a double-sided configuration of metal latches.

This miniature connector is typically utilized in tight spaces, like those found in mobile phones, gaming consoles, laptops, and appliances, where its small form factor, high reliability, and comprehensive range of pin sizes makes it ideal for soldering or wiring applications.

Universal Utility

HTSW-138-21-S-D is widely used in a broad range of applications, delivering reliable connection and superior signal transmission. One of the most popular applications for this mini-pin connector is in consumer electronics products, such as televisions and computers, where the plug’s small size, strong contact point, and secure latch are well-suited to connect devices internally or to other peripherals, like headphones.

Another popular application is in automobiles, where HTSW-138-21-S-D connectors are often used to connect audio systems, GPS navigatio devices, and other car-mounted accessories, often with additional insulation to resist the high temperatures from the engine.

In both industrial and commercial environments, HTSW-138-21-S-D is a versatile plug connector thanks to its relatively detachable design—it can be easily disconnected and reconnected even in tight spaces. In addition to consumer electronics, automotive, and commercial/industrial applications, HTSW-138-21-S-D can be used as a power plug, interconnect system, and miniature wire-to-board adapter.

Working Principle

The HTSW-138-21-S-D is a discrete component designed for signal and power transmission. Its core components are pins that are crimped to a wire, covered with an insulating sleeve, and fitted into a housing. The pins are made out of either stainless steel or copper—but copper is preferred for durability and heat conduction—and gold plated to provide additional durability and improve signal transmission quality.

These pins, along with the bin, are core elements for signal transmission. The bin is the portion of the rectangular-shaped plug housing where the pins are fitted in and locks into. The metal latches allow it to securely fasten the connector in place and reduce the risk of accidental detachment. Lastly, the contact points, typically made out of gold, are located at both ends of the pins and ensure reliable connection and high signal transfer quality.

Conclusion

The HTSW-138-21-S-D is a versatile rectangular-shaped plug connector with applications in consumer electronics, automotive, and industrial/commercial sectors. Its small size, secure latch, and reliable contact points makes it ideal for applications requiring signal or power transmission, such as wired/wireless headsets, audio systems, or accessories. The mini-pins are either stainless steel or copper for maximum durability and gold plated for best signal quality. Ultimately, the HTSW-138-21-S-D is a perfect choice for tight spaces and high reliability.
