1. Types of rear panel connectors
The rear panel connectors can be roughly divided into the following categories based on interface types, transmission speeds, and application scenarios:
Backplane connector
Backboard connector is a type of electrical connector mainly used to connect one PCB to another PCB. It has high mechanical strength and stability, and can be divided into three types in the industry: low-speed backboard, medium speed backboard, and high-speed backboard.
Low speed backplane connectors, such as DIN 41612, support speeds up to 1Gb/s and are mainly used in applications such as the telecommunications industry where speed requirements are not high.
Medium speed backplane connector: With speeds ranging from 4Gb/s to 5Gb/s, it meets the needs of many modular and complex server systems.
High speed backplane connector: Supports transmission speeds from 1Gb/s to 112Gb/s, made of thick gold coating to improve reliability and conductivity.
Optical backplane connector
Optical backplane connectors are mainly used for fiber optic communication, providing two types: self-locking and non locking. The self-locking optical backplane connector has an additional Z-axis travel and can provide a floating slow motion card according to the design tolerance of the backplane. This type of connector is usually installed on the back panel, allowing the fiber optic to pass through and reach the back of the casing.
RJ connector (Registered Jack)
RJ connectors, especially RJ45, are standard 8-bit modular interfaces commonly used for computer network connections. It adopts a modular design that can be easily plugged in and out, and is a common rear panel connector in devices such as computers and routers.
Circular connector
Circular connectors are widely used in the connection of aerospace equipment due to their structural characteristics, also known as aviation plugs. Although it is mainly used in high-end fields, circular connectors are also a good choice in certain rear panel connection scenarios that require high reliability and sealing.
D-type connector
D-type connectors are divided into ordinary and high-density types, with different choices of core numbers (such as 9 cores, 15 cores, 25 cores, etc.). This type of connector is commonly used for data transmission and control signal connections, and is also suitable for certain rear panel connection requirements.
2. Characteristics of rear panel connectors
The rear panel connector has the following characteristics:
Diversity: There are various types of rear panel connectors that can meet the needs of different devices and application scenarios.
Stability: These connectors are typically manufactured with high-quality materials and processes to ensure stable connection performance in complex environments.
Modular: Many rear panel connectors adopt a modular design, which is easy to install, maintain, and upgrade.
High speed: With the continuous advancement of technology, the transmission speed of the rear panel connector is also constantly improving to meet the needs of high-speed data transmission.
3. Application of rear panel connectors
Rear panel connectors are widely used in various electronic devices and communication systems, such as servers, routers, switches, industrial control equipment, etc. They play an important role in connecting external devices, expanding functionality, and maintaining system stability among these devices.
