Dual Row USB Connector

Dual Row USB connector is a USB CONNECTOR structure with two rows of pins or terminals, which is usually used for signal transmission, power supply and data interface connection inside electronic equipment. Compared with the traditional single-row USB Interface, the dual-row design provides higher wiring density and stronger signal connection capability, which is suitable for electronic equipment that requires multi-channel USB signal transmission or expansion functions. This type of connector is commonly found in internal circuits such as motherboards, embedded systems, communication equipment, industrial controllers, etc., usually with USB 2.0 or USB 3.0 specifications, and can also be customized for specific purposes.

Application:

Connection between the motherboard and the front USB interface to achieve data transmission and power supply functions.

As a peripheral expansion interface in embedded systems, such as connecting cameras, sensors, keyboards, etc.

Multi-channel USB module connection in industrial control equipment.

Use dual-row layout to save space in multi-interface panel design.

Used for modular USB signal distribution in communication equipment.

Modular communication connection between servers and cabinet equipment.

Quick signal connection in medical or security equipment.

Since the double-row structure provides greater connection capacity in a limited space, it is particularly suitable for electronic systems with high requirements for compactness and versatility.

Material:

Insulating shell material: Mostly thermoplastics such as PBT, PA66 (nylon), LCP, etc. are used, which have good insulation, heat resistance and flame retardant properties.

Conductive contact terminals: Phosphor bronze or brass materials are often used, which have good elasticity and conductivity, and are electroplated to enhance corrosion resistance and conduction performance.

Electroplating layer: The surface is usually plated with gold, tin or nickel, and gold plating can improve conduction performance and service life.

Shielding cover/metal shell: For occasions with high anti-interference requirements, metal covers made of stainless steel or nickel-plated copper are used to play an electromagnetic shielding and structural protection role.

The choice of material directly affects the durability, electrical performance, plug-in and unplug times and environmental adaptability of the connector.

Features:

Dual-row design: Provides more pins or interface positions to support multi-channel signal transmission.

Compact layout: Achieve higher connection density in limited PCB space, suitable for miniaturized devices.

Multiple installation methods: Support direct insertion (DIP), surface mount (SMD) or mixed installation methods.

Support high-speed transmission: Comply with USB 2.0, 3.0 and even USB 3.1 specifications, support data rates up to 5Gbps or even 10Gbps.

Stable structure: Some models are designed with locks or reinforcement plates to improve plug-in stability and shock resistance.

Dust-proof and anti-corrosion: Surface plating and plastic materials can resist external corrosive environments.

Diverse interfaces: It can be a double-row version of USB structure such as type A, type B, Micro, Mini, etc. to meet different application requirements.

Advantages:

Higher connection density: Provide more signal connection capabilities at the same size and improve PCB wiring flexibility.

Space saving: Double-row arrangement can effectively utilize PCB surface area, especially suitable for miniaturized and highly integrated devices.

Improve performance stability: Multiple ground pins can achieve better electrical isolation and signal integrity.

Strong expansion capability: multiple USB interfaces can share a connector module, which is convenient for device function expansion.

Strong adaptability: supports multiple fixing methods and shielding structures, suitable for a variety of industrial environments and electronic structures.

Long plug-in life: high-quality contact materials and electroplating layer design can withstand thousands of plug-ins and plug-ins, suitable for long-term use of equipment.

Conducive to mass automated production: standardized pin spacing and packaging form are suitable for SMT and DIP automatic mounting, improving production efficiency.

High degree of customizability: supports multi-dimensional customization such as pin layout, electrical performance, shielding structure, appearance color, etc., which is convenient for branded product design.

The versatility and high adaptability of this connector make it widely used in many fields such as industry, consumer electronics, communications, automotive, and medical.

FAQ:

When should Dual Row USB Connector be chosen instead of Single Row USB?

When the device requires multiple USB channels or interfaces but space is limited, the dual-row connector can achieve more functional connections in the same or smaller area, which is an ideal choice for compact systems

What data transmission specifications does the Dual Row USB Connector support?

Usually supports USB 2.0 high speed 480Mbps, some models can support USB 3.0 or 3.1 specifications, with transmission rates of up to 5Gbps and 10Gbps respectively, depending on the pin configuration and cable structure

How to determine whether the installation method of the double-row connector is suitable for the PCB board?

It is necessary to refer to its pin spacing (usually 2.0mm or 2.54mm), whether it is a straight plug or patch type, and match the corresponding installation form according to the circuit board wiring layout

Does the double-row USB connector support customization?

Support, manufacturers can customize the pin layout, electroplating materials, shielding design, color, interface direction, etc. according to customer needs to meet specific structural and performance requirements

How many plug-in and unplug times are the service life of a double-row USB connector?

The plug-in and unplug life of a high-quality double-row USB connector can reach more than 5,000 times, and industrial-grade products can even exceed 10,000 times, ensuring stable performance under long-term use
