90122-0778

Rectangular Connectors, have two main types: Headers and Male Pins. 90122-0778 connector is an example of two-position, locking headers.

Headers are often times used to connect electronic components on a printed circuit board (PCB). A header is typically a two- or three-piece assembly consisting of a plastic housing and two metal pins. The metal pins are spaced exactly so as to create a contacts and a positive locking mechanism.

Male pins, explained simply, are the opposite of headers, and are usually the connectors on the ends of cables. In contrast to headers, male pin connectors, as the name implies, are made up of a metal pin that is electrically connected to a wire and a metal ring that connects to the wire. Connections are often made of conductive plastic.

90122-0778 connector, is a simple push-on, two-position, locking headers. It is made up of a plastic housing and two metal pins housed inside the housing. The two pins are spaced to match the internal spacing of a PCB. The plastic housing is equipped with a positive locking mechanism that prevents the connectors from unplugging or becoming loose, thus maintaining a reliable connection.

When it comes to the 90122-0778’s applications, they are most commonly used for making connections between PCBs and devices that need to be mounted on a PCB. They can also be used to connect boards to other boards, such as breakout boards, and as part of ribbon cables, Ethernet, and video cables. The locking feature makes them ideal for these applications, as it ensures that there is no risk of the connector becoming loose from vibration or shock. Additionally, these connectors are often used for devices that need to be powered, like USB hubs or hubs for multiple devices.

The working principle of the 90122-0778 connector is quite simple. When connecting the device to a PCB, the pins of the connector are inserted into the PCB, and the plastic housing is then pushed down over the pins and held in place by the locking mechanism. This keeps the pins in contact and is held in place by the locking mechanism. This allows the pins to maintain contact and create a reliable connection.

In summary, the 90122-0778 is a two-position, locking header that can be used to make connections between PCBs and other devices. Its locking feature allows for a reliable connection, and it is often used for devices that need to be powered. The working principle is simple - when connecting the device to a PCB, the pins of the connector are inserted into the PCB, and the plastic housing is then pushed down over the pins and held in place by the locking mechanism.
