IntroductionThe 3-644628-7 is a rectangular connector, specifically a header with male pins. This type of connector is commonly used in a variety of electronic and electrical applications for connecting, disconnecting, and transferring electrical power, data, and/or signals. It comes in standard and custom sizes with different pin counts, varying levels of current and voltage ratings, and a variety of mounting configurations.Application FieldThe 3-644628-7 can be used in a wide range of electrical and electronic applications, including I/O control, computer peripherals, automotive electronics, consumer electronics, lighting, industrial automation, aerospace, military, and medical equipment. In all of these fields, it is used to connect and disconnect two or more circuits in order to enable or disable the flow of electrical current, as well as to transfer data or signals.Design and ConstructionThe 3-644628-7 is a rectangular connector consisting of a housing with a base, a top, and a number of pins along the bottom. The housing is made of a thermoplastic material, typically ABS or nylon. The pins are made of copper or brass, and are typically plated with gold for corrosion resistance. The pins have a variety of shapes and sizes, depending on the application. Some pins have an angled end to facilitate reliable contact with a mating part, while others are straight for increased contact pressure.Working Principle The working principle of the 3-644628-7 is simple and straightforward: the connector is inserted into its mating part, forming an electrical connection between the two circuits. This connection allows for the transfer of electrical power, data, and/or signals from one circuit to another.The pins of the 3-644628-7 are designed to provide reliable contact with its mating part. The pins have sleeves that hold the pins in place and ensure that they remain firmly in place even under harsh environments or conditions. The sleeves also protect the pins from corrosion and wear.Installation and Maintenance The 3-644628-7 is designed to be user-friendly and relatively easy to install. The connector is typically mounted through holes in the application\'s panel with standard mounting hardware. The pins can be soldered into place or, in some cases, the connector can be crimped onto the mating wires. Once the 3-644628-7 is in place, it requires minimal maintenance. Its thermoplastic housing and gold-plated pins allow it to resist corrosion and wear, increasing its overall lifespan and making it relatively resilient against damage. The connector is also designed to be easy to remove or replace if necessary.Conclusion The 3-644628-7 is a rectangular connector, specifically a header with male pins. It is designed for use in a wide range of electronic and electrical applications, and is commonly used to connect, disconnect, and transfer electrical power, data, and/or signals. The connector is easy to install and maintain, and is relatively corrosion and wear resistant. All of these features make it an ideal choice for a variety of applications.
