175778-4

Rectangular Connectors - Housings

The 175778-4 connector is a rectangular type electrical connector housing. It is used to connect two wires or cables that require a secure, mechanical connection. It is a very reliable, widely used connector housing with excellent performance. This connector is designed to meet the criteria of SAE AE-7307-22 specification. It is commonly used in a variety of industries such as automotive, medical, aerospace, and industrial applications.

Application Field and Working Principle

The 175778-4 connector is used in applications where highly reliable electrical connections are vital or essential, such as those in the automotive, medical, aerospace, and industrial industries. Additionally, it is ideal in high vibration applications, where the connector must withstand high temperature and shock loads.

The connector housing is made of a durable, protective material to ensure excellent mechanical performance in harsh environmental conditions. The contacts inside the housing are typically made from brass or aluminum alloy which provide a good electrical connection. Additionally, the contacts are designed to provide a temperature rating of 155°C (311°F). The insert arrangement provides superior electrical performance, with a low contact resistance (less than 30 mΩ at 20 mA).

The connector housing features a unique locking mechanism that utilizes a metal latch which engages the male contact to provide a secure, quick connection. The latch is designed to maximize the contact force and provide a high level of vibration resistance.

This connector is an ideal choice for applications where reliable electrical connections are required in harsh environmental conditions. It provides excellent performance, a high temperature rating, and superior mechanical and electrical performance.
