Terminals - Knife Connectors

Introduction

Knife connectors are an important component of electronic systems, and have been a mainstay in the industry for years. They are used in the interconnection of components, as well as for providing the electrical connection between components. Knife connectors are also widely used in the interconnection of board-to-board and panel-to-board systems. Typically, knife connectors employ a variety of contact configurations, such as straight and right-angle, and board-level, panel-level, edge-level, and surface mount designs.

31939 Application Field and Working Principle

The 31939 connector is a 2-piece knife connector designed to meet the most demanding requirements of industrial and commercial applications. The 2-piece construction of the 31939 allows for greater flexibility in mating design and provides a secure, reliable connection with minimal risk of contact damage due to misalignment. The two-piece design of the 31939 also eliminates the need for multiple keys and terminals, simplifying the assembly and wiring process.In addition, the 31939 features a simple, intuitive design that allows for quick, easy assembly and reduced wiring time. It is designed with two terminals and one key, and the terminal and key contacts are color coded for simplified assembly and wiring. The terminal contacts are configured to ensure proper mating and provide a secure connection, while the key contact ensures proper assembly of the two parts. The 31939 is designed to provide excellent electrical connection and reliable signal transmission, even in hostile environment conditions.The two terminals of the 31939 connector are equipped with a safety lock to ensure that the two parts are properly aligned and secure. The terminals are designed to achieve a minimum of 1.5mOhm of contact resistance. And, the key contact features a unique geometry that ensures proper assembly and eliminates the possibility of mistakes during assembly.
