Introduction

Rectangular Connectors - Headers, Male Pins 0533980876, commonly referred to as HMPP, are a type of electrical connectors utilized in a variety of applications. Compared to alternative electrical connector types such as circular, cable or other specialist connectivity solutions, HMPP are highly versatile and offer a viable solution to a large array of electrical connections. This article will provide an overview of the application fields and the working principle of HMPP connectors.

What are HMPP Connectors?

HMPP connectors are a type of rectangular electrical connector that uses both male and female contacts in order to make a secure electrical connection. These connectors come in a variety of sizes and materials and can be used in a wide range of applications. They are widely used in automotive, telecommunications and industrial sectors, due to their ability to provide a secure connection with low impedance. HMPP connectors consist of two rows of male and female contacts and are typically found on either one side or both sides of each header. They are typically constructed from metal or a combination of metal and plastic, with some manufacturers utilizing voltage tolerant polymers to ensure the highest levels of reliability.

Application Fields of HMPP Connectors

Due to their versatility, HMPP connectors have a wide range of applications across multiple industries. They are suitable for controlling and transmitting a variety of electrical and signal currents, and are especially effective at low signal frequencies. The automotive industry is a major user of HMPP connectors, with a wide variety of application fields for the connectors. These include: engine management systems, electronic stability control, air bag systems and high voltage bus systems. The telecommunications sector is also a major user of HMPP connectors, where they are popular within modular handset design, as well as providing flexibility and low impedance for connecting a mobile phone to an antenna system. This includes application fields such as door security systems, vending machines, and flight telemetry systems. In terms of industries, HMPP connectors are also popular in aerospace, medical, and consumer electronics due to their ability to provide low impedance, high current solutions.

Working Principle of HMPP Connectors

The working principle of HMPP connectors is based on maintaining tight contact tolerances between male and female contacts. This is achieved by using a solid contact pin and spring clip arrangement. The pin, which is typically made from copper or an alloy, is inserted into the female contact point and a clip is inserted into the male contact point. The clip is designed to create a strong electrical connection between the two points and to ensure that the contact is held firmly in place. This connection is highly reliable and provides low impedance, which aids in the effective transmission of electric and signal currents. To further improve the contact retention of the connector, some manufacturers also employ a locking mechanism between the male and female contacts. This involves the use of a pin inserted between the contacts, which locks the connector in place and prevents accidental disconnection.

Conclusion

HMPP connectors are highly versatile and can be used in a wide range of applications. They offer excellent electrical properties and are capable of providing secure connections, low impedance and strong contact retention. The working principle of HMPP connectors involves the use of a pin and a spring clip to maintain a tight contact tolerance between the male and female contacts. Due to their versatility, HMPP connectors are commonly used in a variety of industries, including, automotive, telecommunications and industrial.
