Backplane Connectors - Housings

Backplane connectors, also known as board-to-board connectors, consist of a plastic housing or receptacle to which multiple printed circuit board (PCB) connectors are mounted. They are used to link PCBs on the board, and can also be used to facilitate electrical path between various computers and connected devices.Backplane connectors have a diverse range of applications and are commonly used in the telecommunications, computer, automotive, and consumer electronics industries. They are also used for LED lighting, security systems, motor control, test and measurement equipment, LCD displays, and many other applications.Backplane connectors offer a wide variety of features that make them applicable for a range of applications. These features include high-speed data transmission, high current carrying capacity, power, transmission line, and shielding capability.Backplane connectors come in a variety of shapes, sizes, and mountings, making them suitable for different types of applications. The following housing types are available:

Flat Housings

Flat housings are generally used for high-speed applications such as computer and telecom systems. These are typically constructed from aluminum or other non-metallic materials.

SLH Connectors

SLH (Staggered Layout Housings) connectors feature two staggered rows of pin-n-sockets. These housings are ideal for high-speed applications as they reduce power reflections and crosstalk.

Dual Row Connectors

Dual row connectors are designed for use with two parallel connectors. These are configured in a V-shape, which provides a greater flexibility in the routing of the wires.

Raceway or Low-profile Connectors

Raceway or low-profile connectors are ideal for applications when space is restricted. These are also available in a range of shapes and sizes and can be used in combination with other rectangular or circular connectors.

Power Connectors

Power connectors provide a reliable electrical connection between two PCBs. Power connectors have two parts: a modular connector and a receptacle. The modular connector is mounted to one of the PCBs, while the receptacle is mounted to the other. The power cables are then connected between the two.

Working Principle

Backplane connectors rely on a number of components to ensure a reliable connection between two PCBs. These components include signal pins, power pins, shield pins, and contact pads. At the heart of the connector is the contact.The contact is composed of several parts, including a mating surface which mates to the contact surface of the mating connector, a resistor, an insulation housing, and a terminal. The resistor ensures a low-level current flow between PCBs. The insulation housing provides electrical isolation between the mating connectors and the contact pads. The terminal is used to transfer the signal or power between the contact and PCB.When the connector is mated, the contacts make direct contact between the connector and the PCB, allowing for the transfer of voltage or data signals. For high-speed applications, an additional layer of shielding is added to protect the data signals.Backplane connectors can be used in a wide range of applications and provide reliable and robust connections. By taking advantage of their features and working principles, engineers can ensure a reliable connection between two PCBs.
