USB 3.0 Reverse type Connector

In an era where electronic devices are increasingly pursuing thinness, lightness, and integration, the design of interface components often becomes a key factor restricting product forms. The Reverse Type USB 3.0 AF Side Entry Connector is an innovative component born to solve this problem. With its unique "reverse side-entry" design, it perfectly balances the high-speed performance of USB 3.0 and space efficiency in a limited space.

Product Definition and Core Design

Reverse Type: It breaks the pin and interface orientation logic of traditional USB female connectors, providing flexible adaptability for special circuit layouts. Especially in devices with dense multi-interface arrangements, it can avoid physical interference between interfaces.

Side Entry: The interface connects to the circuit board from the side, converting the "vertical space occupation" of traditional straight-plug female connectors into a "horizontal layout advantage", increasing the internal space utilization of the device by more than 30%.

USB 3.0 Female (AF): Based on the Type-A female form, it is compatible with the USB 3.0 high-speed transmission protocol and is backward compatible with USB 2.0/1.1 devices, covering the interface needs of most consumer electronics and industrial equipment.

Structure

Metal Shell

The shell made of nickel-plated cold-rolled copper is the "first line of defense" of the connector:

Electromagnetic Shielding: It effectively blocks external electromagnetic interference, ensuring a low bit error rate when USB 3.0 high-speed differential signals (TX±, RX±) are transmitted, which is crucial for stable transmission at a speed of 5Gbps.

Mechanical Strength: It can withstand more than 5,000 plug-in operations, and can maintain structural integrity for a long time in scenarios such as frequent debugging of industrial equipment and daily use of consumer electronics.

Heat Dissipation Assistance: The thermal conductivity of the metal material can quickly export the heat generated by the interface due to high loads (such as fast charging and high-speed transmission), avoiding performance degradation caused by overheating.

Plastic Core and Pins

Plastic Core: Made of high-temperature resistant LCP liquid crystal polymer, the blue appearance is a标志性 feature of USB 3.0 female connectors. Its heat resistance can meet the high-temperature welding requirements of SMT patch process, while ensuring the long-term stability of pin arrangement.

Pins: Made of gold-plated phosphor bronze material, the gold layer thickness is ≥0.8μm. The elasticity of phosphor bronze makes the pins maintain stable contact pressure during plugging and unplugging, and the gold-plated layer controls the contact resistance below 5mΩ (far better than the industry standard of ≤10mΩ). The pins have clear functional partitions, including power pins (Vbus, GND) and data pins (D+, D-) compatible with USB 2.0, as well as USB 3.0 high-speed differential pairs (TX±, RX±), achieving the dual goals of "high-speed transmission" and "device compatibility".

High Speed and Reliability of USB 3.0

As a practitioner of the USB 3.0 standard, this connector does not compromise on performance parameters:

Transmission Speed: The theoretical peak speed of 5Gbps means that it only takes about 3 seconds to transfer a 1GB high-definition video (in an ideal environment), which is more than 10 times that of USB 2.0 (480Mbps), completely solving the efficiency pain point of large file transfer.

Electrical Parameters: The design of rated voltage 30V DC and rated current 1.8A supports the USB BC 1.2 fast charging protocol, which can efficiently supply power to devices such as mobile phones and tablets.

Environmental Adaptability: The wide temperature working range of -55℃ to +85℃, combined with the corrosion resistance of gold-plated pins, enables it to operate stably in extreme scenarios such as cold outdoor testing equipment and high-temperature industrial control hosts.

KKG Electronics, each part of the use of temperature-resistant materials, high-temperature testing equipment 260 ℃ for 5 minutes, the appearance of the product does not change!   

A Tool for "Thinning and Lightening" of Consumer Electronics

In ultra-thin laptops (such as MacBook Air) and 2-in-1 tablets (such as Surface Pro), the side-entry design allows the USB interface to be integrated into the narrow space on the side of the device, maintaining the thin and light form of the device while retaining high-speed expansion capabilities. Even in mini docking stations, the integration of multiple side-entry female connectors can reduce the product volume by 40%, meeting users' "portability" needs.

Guarantee of "Durability" for Industrial Equipment

Industrial control PLCs, medical monitors and other equipment have strict requirements for "reliability" and "environmental adaptability" of interfaces. The side-entry design avoids the defect that straight-plug interfaces are easily damaged by collision. The gold-plated pins and metal shell ensure long-term stable operation in high-humidity and dusty industrial environments, making it a key interface component in the process of production line automation and medical digitization.

"Hidden" Choice for Vehicle-Mounted and Embedded Systems

In the hidden interface of the vehicle-mounted central control and the compact panel of the embedded host, the side-entry connector can realize "interface invisibility"it not only keeps the appearance of the device concise and beautiful, but also can provide high-speed data transmission and power supply when needed, taking into account functionality and design sense.

From the thin and light revolution of consumer electronics to the reliable upgrade of industrial equipment, the Reverse Type USB 3.0 AF Side Entry Connector redefines the high-speed interface standard in compact scenarios with its innovative structural design and excellent performance. It is not only a connector, but also an "invisible driver" for device form evolution and performance leap, promoting the electronics industry to move towards a more efficient and intelligent direction in a limited space.
