What is an Extremely Fine Coaxial Connector?
Extremely fine coaxial cable connectors are mainly used to connect digital signals between module boards via differential transmission over extremely fine coaxial cable. For proper signal transmission, the center conductor of the transmitted signal needs to be connected to the signal circuitry on the PCB via the terminals of the connector. The outer conductor of the cable needs to be electrically connected to the PCB via the metal part of the connector, the housing. The electrical connection of the outer conductor to the PCB through the connector housing is called "grounding".
History of Extremely Fine Coaxial Wire Connectors
Extremely fine coaxial cables have an outer conductor that provides electromagnetic shielding, making the electrical signals transmitted through the center conductor less susceptible to external electromagnetic waves (or electromagnetic noise). This gives the cable a high degree of flexibility and high shielding performance. In order to realize these advantages, it is necessary to process and terminate these small cables one by one, so that very fine coaxial cables can be used as jumper connections for digital signals. In the past, extremely fine coaxial cables were only used in a few pieces of equipment, such as expensive medical equipment, and were not widely used in general consumer electronics because it was difficult to produce cables of consistent quality.
Notebook computers, which began to be widely used in the 1990s, are equipped with color LCD screens with higher image quality and faster display transmission speeds. As a result, very fine coaxial cables became a flexible connection method for turning monitors on and off while providing high-speed transmission performance, and it began to attract attention. i-PEX pioneered the development of a connector that efficiently and stably connects micro-coaxial cables and created the technology to connect these small-sized cables to the connector. 1996 saw the announcement of the world's first very fine coaxial connector, "CABLINE®I. I-PEX announced the world's first extremely thin coaxial connector "CABLINE®I" for differential transmission of digital signals. As a result, it was adopted in consumer notebook computers as a jumper connection for digital signals using very fine coaxial connectors.
Extremely Fine Coaxial Wire Connectors Today and in the Future
. With the development of high-speed Internet and the increased use of mass storage devices, high-resolution images and videos can be more easily shared on consumer products such as personal computers, tablets, and smartphones. The amount of information that needs to be processed on these devices has increased dramatically, and the signal speeds of the devices have become faster and faster. When electromagnetic noise is added to the outside of an electronic device, it may generate unintended electrical signals to the device's internal circuitry, causing malfunctions or damage to high-performance electronic components, and may also lead to damage to the electronic device. As the next generation of panel connectors for CABLINE®-VS, I-PEX is also developing a number of EMC-shielded connectors (ZenShield®) to meet a variety of applications and design conditions.ZenShield® connectors, by allowing the connector to be in close proximity to sensitive subsystems (such as transmitter/receiver antennas, which are commonly found in high-performance wireless communication systems), provide the circuit board designers greater flexibility.
As data rates increase, servers use more cable assemblies. These cable assemblies need to be minimized in size so that the server system is easy to assemble while having unobstructed air flow for heat dissipation. Flexibility benefits both high and low speed internal cables, as well as small size and low height. Extremely thin coaxial cables with I-PEX CABLINE® series connectors allow for higher density interconnections, reducing system space for wiring and cable assembly terminations.

2、How to choose a very fine coaxial cable connector? :

Have you ever been confused about how to choose a very fine coaxial connector for high-speed transmission?
--- There are many factors that can make choosing a connector difficult.
To help make your choice easier, this article provides some examples of how you should select the most appropriate connector for your current application.

Have you ever had the following question, "I want to choose a very fine coaxial cable connector, but how do I make a decision?"?
The decisions you make can have far-reaching consequences, as the connector is a very important electronic component that will directly affect the performance of your equipment.
Choosing the wrong connector may prevent you from achieving your target performance.

So, is there a better way to select a very fine coaxial connector?
If you follow the steps below, the selection process can go relatively smoothly.

---------------------------------------------------------------------------------------------------

① Clarify transmission standards

Different devices and components follow different transmission standards. Before selecting a connector, choose the signal to be transmitted. The transmission speed is determined by the transmission standard.
② EMC Mitigation Measures
What is Electromagnetic Compatibility (EMC)?
When a signal is transmitted, it emits noise into the surroundings (EMI) and is also affected by ambient noise (EMS). This noise generated by the signal can adversely affect the performance of peripheral devices. Similarly, when environmental noise interferes with a signal, its transmission is adversely affected.

I-PEX's ZenShield® technology helps prevent ambient noise from affecting the signals in the connector and prevents signal-generated noise from affecting external components. This shielding technology gives you more freedom in placing other electronic components and helps to realize high-density mounting, a trend in circuit board mounting.

If you are experiencing noise, here is an example of EMC shielding (ZenShield®).

③ Necessary number of pins
The next step is to select the number of pins required for the application. Choosing a large pin count requires a larger connector, which takes up more space on the PCB. This also increases the cost.
④ Connector Size Description
Connector dimensions are expressed in the height direction, pitch alignment direction and depth direction.
Among the most common limitations are height and spacing dimensions

Why are larger mating sizes for connectors important?
The female chassis of the very fine coaxial connector is mounted on the PCB and then nested with the male chassis harness. If the nesting height is too high, it may interfere with the device housing and prevent the housing from being installed as intended.
What is spacing?
Pitch is the distance from the center of one terminal pin to the center of the next terminal pin.
Why is spacing important?
For very fine coaxial connectors, the connector pitch limits the larger outside diameter of the cable that can be used.

(Example 1: 0.5 mm pitch 10 pin connector, compatible with cables 0.5 mm larger OD).

(Example 2: 0.4 mm pitch 10 pin connector, compatible with cables 0.4 mm larger OD).

The larger the cable diameter, the lower the losses, resulting in better transmission performance.
However, larger cable diameters also take up more space, resulting in thicker harnesses.
⑤ Determine cable size
What is AWG (American Wire Gauge)?
As shown in the figure below, AWG is a number represented by the diameter of the center conductor; the larger the AWG number, the smaller the diameter.

(Image of very fine coaxial cable structure)
Imagine a water passing through a pipe. The wider the pipe, the more water will flow through it. The same applies to a cable. The larger the diameter of the center conductor, the more current flows through it.
Conventional wisdom suggests that you should always use thicker cables. However, as mentioned earlier, the size of the cable used with the connector is also limited by the connector spacing.

2) Features of I-PEX Shielded Connectors
With the development of electronic devices towards high performance, power saving and miniaturization, and the increasing demand for high-speed signals, the number of electronic components operating at low voltage is increasing, and the density of installed electronic components is also increasing. If electromagnetic noise is added from the outside, it may cause unnecessary currents to be generated in the internal circuits of the devices, resulting in malfunctioning or damage to high-performance electronic components, and it may also lead to breakage of electronic devices.... In addition, in electronic devices with wireless communication capabilities (e.g., laptop computers, tablets, and cellular phones), electromagnetic waves generated inside the devices can increase noise in the wireless communication circuits, which can degrade antenna reception performance.
. In this case, generally, the measure for electromagnetic noise inside the equipment is to physically shield the electromagnetic noise by incorporating the electromagnetic noise filter element into the circuit and/or adding a metal shield to the element.
With the introduction of smaller devices with high-density components installed, and the presence of high-speed signals in these devices, it is necessary to take measures against electromagnetic noise at device jumpers.I-PEX has developed a connector series that addresses the problem of electromagnetic noise in connectors with suitable grounding structures and coverings, including mounting locations for signal terminal tails with metal shielding ( ZenShield®). This solution is widely adopted by many customers to prevent electromagnetic interference, especially in high-performance devices equipped with wireless communication features such as Wi-Fi®, GPS, LTE, and others.
