Rectangular Connectors - Housings

638517-5 Application Field and Working Principle

Rectangular connectors are common electrical devices used for connecting various components and circuits. Among these connectors, the 638517-5 rectangular connector is part of the FCN-MPT family of connectors made by 3M. Its application field is mainly in commercial, industrial and institutional markets and applications including power, lighting, communications and machinery.

Design

The 638517-5 is a three-piece connector consisting of a connector body, a Terminal Position Assurance (TPA) feature, and two removable end caps. The connector body is comprised of a non-conductive molded high-performance thermoplastic resinous material. It is waterproof, resistant to flame, and corrosion resistant. The TPA feature is a spring-loaded device placed between the two end caps to provide a foolproof connection and secure mating. It can also be used to prevent incomplete mating due to misalignment. The end caps are made of stainless steel which provides strength and durability.

Usage

The 638517-5 is suitable for use in exposed panel-mounting applications, making it easy to access and maintain after installation. It is also suitable for wet and dry environments. The connector is designed to provide electrical continuity between two electrodes and prevent arcing.

Installation Process

The 638517-5 connector is easy to install. First, the two end caps are inserted into the connector body. Next, the TPA feature is inserted into the connector body, making sure it is properly aligned with the end caps. Finally, the connections are soldered or crimped to the end caps. The connector can be installed quickly without the need for special tools or skills.

Working Principle

Once installed, the 638517-5 connector is designed to provide reliable and efficient electrical continuity between two electrodes. These two electrodes are connected to two cables through soldering or crimping. The electrical continuity is established through the metal contact surface between the two end caps and the TPA. The TPA ensures that the connection is secure and that there is no arcing. This ensures reliable and efficient electricity flow between the two electrodes without any energy losses.The 638517-5 connector offers a wide range of benefits for a variety of applications in commercial, industrial and institutional markets. It is waterproof, resistant to flame and corrosion, and requires no special tools or skills for installation. Furthermore, it is designed to provide reliable and efficient electrical continuity without any energy losses.
