Rectangular Connectors - Headers, Male Pins are used for a variety of applications, including electrical system connections, computer harnesses, automotive wiring, and other industrial applications. The 280371-3 connector is a part of the Rectangular Connector line of products, which include a variety of sizes and types of connectors tailored to fit specific application requirements. The 280371-3 connector is a two-position shielded header designed for higher current applications, reliable mating and low EMI.

General Features

The 280371-3 Rectangular connector features a two-position design with a shielded header. The shielded header provides protection from electromagnetic interference (EMI) and makes it suitable for higher current applications. It is also designed with the convenience of mating and unmating without the aid of a tool. The connector is made of durable materials such as copper alloy and plastic, and is rated according to UL7500 (for in-line connections) and UL 953 (for bulkhead connections).

Connector Body

The 280371-3 connector is a two-position shielded header that features a durable plastic housing with a staked in shell. The body is divided into two long chambers, with one for the solder cups and the other for the wiring openings. The contacts are internal and held in place by an insert located within the body.

Pin Insulator and Contact

The pin insulator and contact of the 280371-3 connector are made of copper alloy and feature a precision crimp termination for reliable contact. The milled slots on the end of the contact make it easier to attach to wires and enable the electrical contact to be tightly secured. The contacts feature a two-level design for ease of assembly. The contacts also feature a gold-plated finish, which helps to prevent oxidation and ensure reliable electrical contact and performance.

Shell Assembly

The 280371-3 connector features a shielded die-cast steel shell. The shell helps to protect the connector from physical damage and provides EMI shielding. It also provides mechanical stability and strain relief for the wiring. Additionally, the shell includes a spring finger which enables a robust mechanical engagement between the mated parts and a robust sealed connection.

Applications and Uses

The 280371-3 connector is primarily used in automotive, industrial, and military applications. The shielded design of the connector makes it suitable for higher current applications, such as those found in the automotive and industrial fields. For military applications, the shielded design helps to protect critical information from being intercepted. Additionally, the connector can be used in a variety of other high-current applications, such as power supplies and electrical system connections.

Working Principle of 280371-3

The 280371-3 connector is designed to provide a secure and reliable connection between two components. It is designed with a two-pin insulator which is connected to a precision crimp contact. The contact is then inserted into the connector body and held in place by an insert. The milled slots in the end of the contact enable secure electrical contact. When two connectors are mated, the spring finger of the shell assembly provides mechanical stability, strain relief, and EMI shielding. The gold-plated finish on the contacts helps to prevent oxidation and ensure reliable electrical contact.
