Rectangular Connectors - Headers, Male Pins

The 90122-0781 application field and working principle fall under the category of rectangular connectors – headers, male pins. Rectangular connectors are physical components used for transmitting signals that take the form of electrical energy, audio, video or data. The main component of an electrical connector is an insulating base, which is secured in place by either screws, bolts, or pins and provides a mechanical frame for the electrical components contained inside. The electrical components are typically made of metal and may include wires, terminal blocks, and metal contacts. Electrical connectors also have a variety of other features, such as sealing rings and clips to maintain secure connections.

Terminal Blocks

Terminal blocks are one type of electrical components found in a header or a pin. These are small rectangular blocks with metal contacts that make electrical connections by pressing the terminals together with a screw or tension spring. The terminals can be removed or replaced without disruption. Terminal blocks typically have one or more contact points, which allow them to be connected to other electrical components. Terminal blocks are commonly used in power supplies, computers, and other electrical equipment for making connections between components.

Metal Contacts

Metal contacts are another component of a header or pin. These metal contacts are placed in between the terminals and are used to make electrical contact between the two terminals. Metal contacts are typically made of copper or brass and are insulated with either ceramic or rubber insulation material. The insulation material usually provides some protection against corrosion and prevents accidental electrocution. Metal contacts can also be used to provide additional contact points for signal or data transmission.

Sealing Rings

Most rectangular connectors also have a variety of sealing rings to prevent moisture from entering the connector. Seal rings are typically cylindrical and made of silicone or rubber material. The seal rings are placed around the metal terminals, preventing moisture from making contact with the electrical components. Sealing rings also reduce the amount of dirt and debris that can accumulate, and ensure that the connector remains free from corrosion.

Clips

Clips are also used in order to maintain secure connections between the terminals. Clips are usually made of either steel or plastic and are designed to hold the terminals securely in place. Some clips may also be used to provide additional contact points for signal or data transmission. Additionally, clips can provide additional strain relief, which helps to reduce the amount of stress put on the terminals.
