Rectangular Connectors - Headers, Receptacles, Female Sockets

Rectangular connectors are used to connect cables and devices in diverse applications, making it possible to create reliable electric circuits. The 91812-106 is a standard rectangular connector, having both a low profile and small size. It is ideal for use in aviation, medical, automotive, industrial, and instrumentation applications. The 91812-106 is typically available in two versions – a straight version and a right angle version.

Design and Construction

The 91812-106 is a two-piece design consisting of an insulator and a receptacle. The insulator is made of a high temperature thermoplastic, and includes a set of metal clip slots, allowing for a secure connection on street cable. The receptacle is made of high-grade copper alloy, with two holes on either end facilitating mounting. The receptacle has a slotted internal structure, which slidably mates with the pins of the corresponding terminal when it is inserted.

Interference Protection

The 91812-106 is designed to provide excellent protection against a broad range of mechanical and electrical interference. The insulator has two internal insulation rings, which prevent unwanted mating between electric circuits. It also has a series of wall ribs, which help ensure proper mating with mating channels. A corrosion-resistant coating is applied to both the insulator and the receptacle. This coating is tough and durable, and provides additional protection against the environment.

Contacts and Connectors

The 91812-106 typically utilizes a combination of pin and socket connections. The pins are designed to be closely fitted together in the receptacle, which helps reduce interference and ensure a reliable connection. The socket connectors are made using a high grade metal alloy, which allows for quick and easy insertion and removal of the pins. Both the pins and sockets are further protected by a series of rubber seals, which help prevent dust and dirt from entering the inside.

Working Principle

The working principle of this connector is fairly simple. When the pin is inserted into the receptacle, the wall ribs within the insulator create a sliding fit, which holds the pin in place. This ensures that the electrical connection is reliably made. The rubber seals on the pins and sockets also help ensure a reliable connection by creating a seal around the inserted pins.

Advantages

The 91812-106 offers several advantages over other similar connectors. It is small, lightweight, and has a low profile, making installation easier in tight spaces. In addition, its two-piece design can be used to easily create customization without damaging the connection. Furthermore, the corrosion-resistant coating helps ensure reliable connection over time, even in challenging environments. Finally, the use of metal alloy pin and socket connectors enhances the security and durability of the connection.

Disadvantages

One of the drawbacks of the 91812-106 is its limited contact size. The contacts cannot accommodate cables larger than 6mm in diameter, which could be a problem in some applications. Additionally, the rubber seals on the pins and sockets may not form an effective seal in high-vibration environments, resulting in poor connection quality.

Conclusion

The 91812-106 is a standard rectangular connector that is suitable for many applications. It is small, lightweight, and has a low profile that makes it ideal for use in aviation, medical, automotive, industrial, and instrumentation applications. Its design features several interference protection measures, such as insulation rings and wall ribs, and its metal alloy pin and socket connectors are highly secure and durable. Although it has some disadvantages, overall, it is a reliable choice for many applications.
