Rectangular Connectors - Housings

1-2132781-1 Connectors are designed to mechanically and electrically join two terminations, and are well-suited for use in panel-mounted applications. These connectors feature a single piece plastic housing, typically ABS or heat stabilized polyester, with integrated thermoplastic cable seals. 1-2132781-1 Connectors are available in several different sizes, and include multiple contact positions in a variety of terminations types. Housings are the portion of the connector that terminates the backshell or thread. Most housings are made from plastic, with UL-recognized flame retardant polycarbonate resin materials.

Application Fields and Working Principles

1-2132781-1 Connectors are often used routing signal and power in automotive, industrial, and consumer applications, such as mass storage, robotics, sensors, agriculture, audio/visual, data/telecommunications, office systems, appliances, DC brush/brushless motor technologies, and marine applications. Typical applications include communications, computer, and network equipment where connector reliability, durability, and high speed are critical. Working principles for this style of connector feature a secure locking central body, which supports an electrical contact holder with an insulated two-piece insulation sleeve. The contact holder contains a set of contacts and electrical conductors for completing the circuit.

The central body connects to the housing and holds the contact holder in place. It features an actuator that works in two stages with a mechanical locking mechanism, to taper and lock the contact holder in place, and a friction locking arrangement that keeps the contacts in place. A wire-lock mechanism ensures the contacts are locked into place even under heavy vibration. It also features recessed contact passages to protect against short circuits, and sloped contact faces that reduce insertion/extraction force.

The contact holder of the 1-2132781-1 Connectors contains special contact structures that provide superior mechanical and electrical performance. The contacts are designed to provide a low-resistance connection when mating and provide high retention force for reliable, long-term connections. The contacts are also designed to provide continuous electrical connection, regardless of installation direction, and feature high-temperature ABS housing material that ensures long-term stability and consistent high performance.

The integrated thermoplastic cable seals provide strain relief, EMI/RFI protection, and secure sealing for cables in 1-2132781-1 Connectors, and come in a variety of sizes and colors to match application requirements. The seals provide a secure connection and stress relief, and are designed for use in temperatures ranging from -20 to 135°C.

1-2132781-1 Connectors are a robust and reliable connectivity solution, and are designed to withstand vibration and temperature fluctuations while providing reliable electrical performance. They feature a high insertion/extraction force that provides superior reliability and durability, and are available in a range of sizes and contact configurations.
