。Introduction
2-640457-1, also known as a Rectangular Connectors - Headers, Male Pins, is one of the most popular electrical connections used in many different applications, such as commercial, military and industrial. It is commonly used to create connections among two or more conductors, in order to transfer electrical power or signal. This type of Connection is typically labeled with two numbers: For example, 2-640457-1, which indicate the size of its pin and cavity connectors. Application Field
2-640457-1 is widely used in a variety of industries and applications. It is often used to connect various peripheral devices to a motherboard or server such as a CD-ROM drive, HDD, light emitting diode, fan or UMTP cable. In addition, it can be used for networking applications and communication between multiple network cards. This type of Connection can also be used to replace standard-sized jumper cables, such as those found in audio amplifiers and digital cameras. Working Principle
2-640457-1 Connection uses a two-piece design that consists of two mating parts, the pin and female cavities. The pin is typically a circular male contact that is inserted into the female cavity, also known as a female receptacle. The materials used for the connection are usually copper, brass, aluminum or gold, and depend on their electro-mechanical properties, as well as the current rating and insulation requirements. The contacts are typically gold or silver plated for superior conductivity and longer life.Once the connection is made, the pins and female cavities create an electrical connection and carry the current from one end to the other. The pins often have a notch or eyelet that helps to ensure proper alignment when making the connection. In addition, a small amount of solder is often applied to the pin to ensure that it is firmly attached to the cavity.Conclusion
2-640457-1 is a reliable and economical choice for a variety of electrical connection needs due to its low cost and ease of installation. It is a common type of connection for many digital and peripheral devices, as well as network connections. It has a two-piece design that consists of a pin and a female cavity and works by creating an electrical connection that allows for the transfer of power or signal. This type of connection is available in a variety of sizes and material types, allowing it to be adapted for different applications.
