ESW-131-39-G-D-LL application field and working principleRectangular Connectors also known as headers are ubiquitous in industrial, aviation, and automotive systems. The ESW-131-39-G-D-LL is a widely used rectangular connector that offers superior electrical performance. The purpose of this article is to discuss the application field and the working principle of this common connector. The ESW-131-39-G-D-LL is a common rectangular connector usually found in aerospace and automotive applications. It is often used as a source of power, automation, and/or signal transmission. It is designed for reliability in harsh and rugged environments. Its superior electrical performance includes low contact resistance, excellent temperature stability, and high impact strength.Working principleThe ESW-131-39-G-D-LL achieves its electrical performance through a special design. It consists of two metal plates, a pair of contacts (which may be gold-plated for increased conductivity), two insulating spacers, and two pairs of retention hooks. The plates are assembled together and embedded in an assembly holder that secures them in their respective positions. The two metal plates are silver-plated to reduce contact resistance and for good electrical connections. The two pairs of retention hooks are used to securely hold the two plates in place. The two insulating spacer bars help to ensure good insulation and protection against potential shock. The contacts, which may be gold-plated, form the electrical connections between the two plates. To make a reliable electrical connection, the contacts must have a tight fit (that is, they must maintain their contact resistance). This is accomplished by a series of compression tests, which are performed at the factory to ensure the accuracy and quality of the contact resistance. The hooks also help maintain the contact resistance.ConclusionThe ESW-131-39-G-D-LL is a common rectangular connector that offers superior electrical performance. It is ideally suited for aerospace and automotive applications that require reliable operation in harsh environments. The design of the ESW-131-39-G-D-LL features two metal plates embedded in an assembly holder with two pairs of retention hooks, two insulating spacer bars, and two pairs of contacts that may be gold-plated for increased conductivity. The contact resistance is maintained through a series of compression tests at the factory.
