Realizing the potential of 5G: the critical role of connectors

由市场经理Paul Pulkowski贡献；Maciek Czerwinski，销售和业务开发总监；销售工程师兼项目经理里克·洛佩兹（Rick Lopez）

The potential of 5G connectivity is nearly limitless with statistics that are difficult to imagine. Analysts predict that worldwide 5G connections will double in 2022 to 1.34 billion, and grow to 3.6 billion by 2025.¹全球5G服务市场规模以2021年结束，价值为652.6亿美元，预计到2028年，年度复合增长（CAGR）为25.9％，价值为3278.3亿美元。²AT＆T，T-Mobile和Verizon Wireless正在竞赛在美国安装其5G基础设施，并采用旨在达到高达20 Gbps的技术，其延迟极低。在2010年至2020年之间，移动数据使用率增长了200倍，预计将增长20,000倍。³

但是我们还不在那里。

Right now, the benefits of 5G are most obvious in personal devices such as smart phones and home appliances like smart thermostats. But as the 5G rollout builds momentum, its impact will be dramatic. Data-heavy applications that benefit from real-time communication will see major advances. These include autonomous vehicles, robotic surgery, medical wearables, traffic management, and of course, IIoT (Industrial Internet of Things) in today’s smart factories among many others.

What does all of this have to do with connectors?
Electrical connectors are a critical part of the infrastructure that enables 5G connectivity. They act as a vital link between the cables carrying data and the devices that communicate information, which have multiplied exponentially. Advances in high speed data transmission have spurred innovation in connector design in terms of performance, size, and electromagnetic signal interference (EMI) shielding. Different versions and sizes are used in communication applications, but M16 connectors have become a go-to for 5G antennas.

对于电池塔天线，对更快，更可靠的数据传输的需求驱动了能够支持特定要求的连接器的开发。由天线界面标准组（AISG）设置。AISG定义了手机天线的“远程电气倾斜”（RET）的通信界面。AISG标准有助于定义RS-485（AISG C485）的AISG连接器，该连接器用于户外应用。⁴The AISG standard has been redefined in terms of electrical and mechanical characteristics, environmental conditions, and materials. (See Figure 1.)

更新的AISG标准包括以下内容：

电气特性：

• Rated voltage of 32 V
• Current carrying capacity of 5 A per contact
• 接触电阻（≤5MΩ）
• Insulation resistance (≥10⁸Ω)

Mechanical characteristics:

• IP68 protection degree
• > 100个交配周期
• Insertion and withdrawal forces of 60 N max
• Keying method
• 振动和电击性
• Cable retention force of 80N

Environmental conditions:

• Harsh environment resistance (protection against temperature, salt mist, sunlight, and rain exposure)

Material and other characteristics:

• 建议使用镍的外壳表面
• 接触金或银的电镀
• 压接或焊接
• 8销，使用4至5个销钉
• M16 x 0.75 screw locking system
• EMC shielding

The miniaturization of connectors
As 5G networks and other high speed data transmission applications grow larger each year, connectors have consistently become smaller. Circular connectors are challenged to save space and weight and handle lightning-fast speeds, all while continuing to provide reliability and the ruggedness that stands up to the harsh conditions 5G cell towers are exposed to. This has tasked design engineers to strike a balance between performance and reliability. The optimal balance will be determined in large part by the application and working with customers to ensure all criteria are met. However, today almost every market, not just communications, demands high performance and durability in a smaller package, so the investment in design is critical for the success of suppliers.

EMI屏蔽
As buildings and other physical objects impede 5G radio frequencies, millions of cell phones, computers, and smart devices create significant potential for disruptions due to EMI. The most effective defense against EMI is filtering at the connector interface.⁵M16连接器的优化360°EMC（电磁兼容性）屏蔽提供了敏感信号和功率连接的最高完整性。屏蔽为金属，可作为电缆夹或屏蔽环。

Effective shielding meets the attenuation requirements of the DIN 47250-6 standard. Attenuation is the loss of signal strength in network cables or connections during transmission. It is typically measured in decibels or voltage. (See Figure 2.)

圆形连接器市场的积极前景继续
截至2019年底，全球连接器市场的价值为641.7亿美元。预计从2020年到2027年，它的复合年增长率为6.7％，在2027年的市场规模超过980亿美元。⁷这个数字包括所有连接器类型——表面cal, I/O, circular, printed circuit board (PCB) and others. Circular connectors account for approximately 7% of the total market, for sales of $4.3 billion in 2020. While the COVID-19 pandemic hit most markets, circular connectors declined only 1.4% and are now recovering with encouraging strength.⁸As 5G, IIoT, and other Industry 4.0 applications expand, so will the need for higher-performing, smaller, and lighter connectors.
