Rectangular connectors are used in virtually every type of electrical device, from simple hand tools to complex industrial and consumer products. Generally, they are designed to make electrical connections between two components that require the same electrical characteristics. The connectors come in various shapes and sizes, but one of the most common is the 91931-31121 series. This article will explain the application field and working principle of the 91931-31121 rectangular connector.

Application Field

The 91931-31121 rectangular connector is typically used in applications where space is limited or the connector needs to be secured in a particular orientation. It is most commonly used in industrial applications, such as machine and equipment control, instrumentation, security systems, communication equipment, and more. It is also commonly found in audio and video equipment.

Working Principle

The 91931-31121 rectangular connector is a two-piece assembly that consists of a mating shield and an adapter. The shield is made out of durable, non-conductive plastic and houses the pins and sockets. The adapter is used to securely connect the pins or sockets to a component and is also made out of durable plastic. The pins and sockets are typically gold-plated for better electrical conduction. The connector is secured in place by screwing it into the specific component.

When the connector is fully connected, the pin and socket contacts are held in place by the adapter. The contacts are then connected and electrical current flows through them. When disconnecting the rectangular connector, the pins and sockets are easily released by unscrewing the adapter.

Conclusion

The 91931-31121 is a popular rectangular connector due to its ability to be securely connected and its ability to make reliable electrical connections in a variety of applications. Its two-piece assembly makes it easy to assemble and it is relatively easy to disconnect as well. The contacts are gold-plated for better electrical conduction. With its wide range of applications, the 91931-31121 is a practical and useful connector to have.
