77311-122-35LF

77311-122-35LF is an example of a rectangular connector header with male pins. It is typically used for application in low-voltage, high-accuracy signal transmission. This connector is commonly used in applications such as hard disk drive subsystem connector, printer connections, cell phone charger and medical instrument applications.

Structure

77311-122-35LF rectangular connectors consist of two parts: the header and the male pins.

The header of the connector consists of multiple rows of metal terminals, which is insulated from each other by plastic walls. Plastic posts are usually used to separate the header into two parts for more stability and easier mating process. Generally, the header is a one-piece body, and sometimes stamped steel and die-cast solder components are used.

The male pins are also made of metal such as brass, but other materials such as phosphor bronze, steel and alumel can also be used. They have a round or square head on the top and an inner terminal at the bottom. The height of each pin may be different depending on the application.

Working Principle

The working principle of 77311-122-35LF rectangular connectors is very simple. When the connector is properly mated, the corresponding terminals of the male pins and the header will touch and produce an electrical connection. Then, the signals can be transmitted through the connector.

When connecting a 77311-122-35LF rectangular connector, mating the male pins and header must be done correctly. First, each row of the header must be aligned with the corresponding row of pins. Then, the two parts must be aligned and pressed together until the pins completely fit into the corresponding slots of the header. The mated connectors should be firmly clasped without excessive force or vibration. After that, signal transmission will work normally.

Advantages

77311-122-35LF rectangular connectors offer a variety of advantages. First, they are easy to assemble due to their simple structure. Second, they are cost efficient and provide a reliable connection for a variety of high-accuracy signal transmissions. Furthermore, the materials used are resistant to oxidation, meaning the connectors will maintain their electrical connection over a long period of time.

In addition, the 77311-122-35LF connectors have the ability to be stackable, which can greatly reduce the space occupied by wiring during installation. They are also very durable and can withstand high vibration, heat, and environmental stress. Due to their reliable locking mechanism, accidental breakage or disconnection can be prevented.

Disadvantages

Although 77311-122-35LF connectors come with many advantages, they also have a few drawbacks. For example, when connected, they have a large volume and occupy more space than other types of connectors. Furthermore, since they require manual assembly, it can be challenging to quickly produce large volumes of the connectors due to time constraints. Additionally, the same tools are needed to both loosen and re-tighten the connectors, resulting in more time and effort spent on assembly.

Conclusion

In conclusion, 77311-122-35LF rectangular connectors are a reliable type of connectors commonly used in applications such as hard disk drive subsystems, cell phone chargers, medical instruments, and printers. The structure of the connector consist of two parts, a header and male pins, that are easy to assemble and provide a reliable connection for a variety of high-accuracy signals. Although the connectors occupy more space than other types and require manual assembly, they offer many advantages such as increased durability, resistance to oxidation, less heat dissipation, and stackability.
