Heavy Duty Connectors - Housings, Hoods, Bases
The 1420909 Connector is primarily used in the aircraft industry as a heavy duty connector. In this application, the Connector must meet the requirements of MIL-DTL-282021 – Aviation Grade Connectors 4 Pin Heavy Duty Connectors. This is an industry standard specification for connector systems used in aircraft and is one of the most important requirements for the 1420909. The 1420909 Connector is composed of a housing, hood, base, insert, terminal and contact assembly. The housing is composed of an upper and lower part, each with two threaded posts for mounting the assemblies. The upper part of the housing is the key component in the design as it holds the contacts and terminals, as well as helping keep the wires secure. The lower part of the housing slides into the upper to form the complete housing. The hood is used to cover the housing, keeping it isolated from the environment, and can be adjusted to fit different sizes of the housing. The hood also has two threaded posts to affix the base, as well as three small fingers that snap onto a groove in the upper part of the hood. This ensures the hood is securely fastened to the housing. The base connects the connector to the application and has two pre-drilled holes to affix it to the application. The base also has provisions for mounting wires to the connector. The contact and terminal assembly completes the 1420909 by providing the actual electrical connections. The terminal and contact assembly consists of a male beryllium copper terminal (also available in brass and copper) and a female nickel-plated steel contact. The contact is also available in stainless steel. The working principle of the 1420909 is very straightforward. When the hood is put in place, it creates a seal around the housing that isolates the contacts from the environment. When the base is connected, the contacts are then connected to the application. The contacts then make electrical contact when a voltage is applied, and current flows when a load is placed across the contacts.The 1420909 connector provides a reliable, heavy duty connection for a variety of applications, including avionics and general aviation. The design is simple yet effective and can handle the extreme conditions found in aircraft and other industrial applications. The 1420909 meets the MIL-DTL-282021 requirements, providing a quality connector that will exceed the industry standards.
