286174-Pin Header Connectors

286174-pin header connectors are rectangular connectors, often referred to as headers, that have two rows of contacts with 176 pins per row. They are primarily used as connectors for prototyping and short-term applications where users need to be able to easily connect and disconnect circuit boards, cables, and other components. They are widely used in a variety of industries, including test and measurement, audio/visual, automotive, and medical.

Applications

286174-pin header connectors are used in many different applications, including prototyping, interconnecting circuit boards, connecting cables to boards, and backplane connections. They are also commonly used in the automotive industry for applications that require two separate parts that need to be connected. In test and measurement applications, 286174-pin header connectors provide a reliable, cost-effective solution for connecting circuit boards, cables, and wires.

They are also widely used in audio/visual and medical equipment, where they provide a reliable interconnect for components that need to be quickly connected and disconnected. For example, they are often used in medical electronics such as defibrillators and cardiac monitors, where quick and reliable connection is essential.

Working Principle

286174-pin header connectors are typically composed of an insulating body and two rows of pins or sockets. The pins or sockets are arranged in two parallel sets in either a straight or right-angle arrangement. The pins or sockets are inserted into the insulating body and held in place with a locking mechanism, such as a snap or spring. A lockable plug is then inserted into the connector, which secures the connection.

Most 286174-pin header connectors have polarized contact arrangements to prevent incorrect connection. This is achieved by having one row of pins or sockets that have an enlarged section, while the other row has a corresponding cut-out. This ensures that the correct arrangement is made when connecting the two parts, and prevents the pins or sockets from being damaged during insertion.

Material and Construction

286174-pin header connectors are typically made of high temperature thermoplastic or PBT/PA materials. The contacts are typically made of brass or phosphor bronze. They can also be plated with gold or tin to provide better conductivity. The insulator and body are often injection molded for repeatable performance.

Types

286174-pin header connectors can come in various forms, including straight, right angles, surface mount, and multiple piece. Straight connectors are ideal for applications where the boards, cables, and components are aligned. Right angled connectors are used when a straight connection is not possible due to space restrictions. Surface mount connectors are used when boards need to be connected without visible wires.

Multiple piece connectors are also available. These are typically composed of separate parts that are connected together. This is beneficial when two components need to be connected, but cannot be connected directly. For example, a cable with a different type of connector can be connected to a board with a 286174-pin header connector using a two-piece connector.

Durability and Reliability

286174-pin header connectors are highly reliable and durable. They are designed for repeated use and can withstand thousands of plugging and unplugging cycles. The pins or sockets are also designed to resist wear and tear, and can handle a wide range of voltages and currents. The insulation is also designed to stand up to harsh environments, including dust and moisture.

Conclusion

286174-pin header connectors are a robust and reliable solution for connecting two components. They are widely used in a variety of applications, including automotive, audio/visual, test and measurement, and medical. The pins or sockets are highly durable and able to withstand thousands of plugging and unplugging cycles. They are also available in a variety of forms, including straight, right angled, surface mount, and multiple piece connectors.
