Enterprise -level low -speed cable component

7 月 21, 2023 通过 admin 0 评论 , , ,

While the data transmission rate is increased, the cable components required by the server are also increasing. Because the printed circuit board has not kept the transmission rate, high -speed cables play a main role. However, the importance of low -speed cable components has not changed. Low -speed components are still often used for power distribution, low -speed signal transmission and auxiliary lines. Low -speed components are rarely defined by industry standards, while high -speed signals are defined by the Standard Committee very frequently. As the density of the server rises, power consumption and heat are also increasing. Therefore, regardless of whether there are standards, all cable components need to be minimized, so that the server system is easy to install and prevent the flow of air flow between the components of the server so as to facilitate heat dissipation.

The advantage of low -speed cables and close -range high -speed cables is that small wire diameters can be used (except, except for power supply). High -density connectors and flexible circuit boards need to use small diameter cables. The smaller the use of the conductor, the more helpful the interconnection density, saving the space required for wiring and cable component connection.

Cable components with small bending radius and easy to wiring

It is essential for high -speed and low -speed internal cables. If the cable can be wiring along the edges or between memory and case, space can be effectively used. Less bending radius can not only reduce the space occupied by the cable, but also effectively use the edge corner of the case.

If the flexibility is insufficient, the component may require a large bending radius to occupy more space. Sometimes the cables need to be wiring along two directions. For example, up and left, the flat cables need to be curved several times, so it is difficult to achieve the steering of the two directions, and the wire beam can easily turn through through the twisting. True connectors are compatible with flexible flexible circuit boards, discrete wires and high -speed impedance control cables. USB or Ethernet is sometimes used as the access interface. They can be wired with low -speed cables.

Cabline® series connector can use various wires

On the front panel of the server with a low -speed cable component, there will be indicator lights, small display screens, and input/output interfaces such as USB and other input/output interfaces. The cable components used in the low -resolution front panel display contain multiple electronic wires, and there may be several pairs of high -speed cables. The LCD display of the small front panel can be set at any position in front of the case, and sometimes it is also set in the hanging ear. These positions are close to the pillar of the cabinet. Because the server is installed here, there will be many sheet metals here. The space that the cable can occupy is limited, and the narrow distance cable component helps to use limited space.

Low -back, miniaturized application

Extreme coaxial components and electronic wire components can be used for extremely low height design. Whether it is a high -speed or low speed, these components have low cup options to save precious space inside the server. It is often used to focus on saving space and lightweight drones, VR devices, and laptops. I-PEX extremely fine coaxial connector and electronic wire connector

I-PEX offers a variety of narrow-spacing output/input connectors. The I-PEX Cabline® series provides a variety of central lines and chimeric directions. The end -connecting electronic wires, shielding wires, impedance control extremely fine coaxials and dual -core coaxials, and even flexible circuit boards (FPCs). If high -speed is required, high -speed and impedance control cables should be selected. Low -speed cable components can use low -cost cables. Although the Cabline connector can be used for high -speed signal transmission, the link performance of the terminal depends on the cable.

Taking the Cabline®-VS polarity coaxial connector as an example, the spacing is 0.5mm, and 10 to 50 PIN feet can be selected. Due to the right -angle mother seat and straight public seat installed with circuit boards, the interface is parallel to the circuit board after installation. The connected options include electronic wires, shielding cables, extremely fine coales, and dual -core coaxials. More compatible with the FPC version. All wiring options of Cabline®-VSF shared a circuit board to install the mother seat. The FPC is an independent option, and the component only uses FPC. Different wires can be mixed with the same component. Electronic cable components contain some high -speed cables very common. If you need to use high -speed cables, the extremely fine coaxial axis can be used for transmission of differential signals. It also provides a shielding option to provide a 360 -degree shield for the connector to help suppress EMI.

Cabline®-CA IIF is suitable for FPC components, and can be compatible with the standard Cabline® CA-II mother seat

I-PEX has the production experience of the narrow-spacing cable components and connectors for decades. According to the system design needs of customers, provide customers with tailor -made solutions

Transmission comparison between ultra-fine coaxial bundle jumper connection and low transmission loss board connection

7 月 21, 2023 通过 admin 0 评论 , , ,

Are you looking for a solution to extend the required transmission distance while suppressing losses? Our ultra-fine coaxial bundle jumper connection can transmit approximately two to three times the distance compared to using a low transmission loss board at any speed.

1. Refer to the specifications for internal loss values; Budget for losses

With the increasing use of high-capacity storage devices, it is easier to appreciate high-resolution images and videos on consumer products such as personal computers, tablets, and smartphones. Therefore, the amount of information that needs to be processed on these devices has sharply increased, and the signal speed in the devices is becoming faster and faster.

However, the higher the speed of signal transmission, the greater the transmission losses such as conductor loss and dielectric loss that occur in the transmission path, making signal transmission more difficult. Therefore, according to transmission standards, there is a reference specification for internal loss values called loss budgeting.

For example, in the USB4 (* 1) specification Ver In the case of 1.0 [Thunderbolt 4 (* 2)], this is a 20Gbps (10GHz)/Lane high-speed transmission, and the loss budget for device A, cable, and device B is specified as -7.5 dB, as shown in the following figure.

2. Typical internal connection mode of USB4 (20Gbps (10GHz)/Lane)

If high-speed signals can be transmitted over long distances on PCB boards within a loss budget range of -7.5 dB, designers will have greater flexibility in designing their PCB boards. (1) When high-speed signals such as USB4 reach a certain transmission distance, low transmission loss boards can be used for transmission. However, the longer the transmission distance, the greater the loss in the transmission path, making it more difficult to transmit signals within the loss budget. Therefore, if the transmission path is long, measures need to be taken to suppress the losses generated in the transmission path.

Although the transmission distance can be extended by using ultra-low transmission loss boards, this may lead to a significant increase in the cost of mass production of products. Other measures to extend the required transmission distance while suppressing losses may be: (2) using jumper transmission paths suitable for high-speed transmission, or (3) using Retimer ICs to correct the attenuated signal waveform and reproduce the original waveform.

In this section, we conducted transmission loss comparison tests on (1) low transmission loss boards and (2) extremely fine coaxial line jumpers

3. Transmission comparison test results of the connection between ultra-fine coaxial bundle jumper and low transmission loss board

3.1 Comparison of transmission losses

CABLINE ®- VS II Very Fine Coaxial Bundle Jumper<Low Transmission Loss Board

3.2 Transmission Distance (USB4 (Thunderbolt 4) Specification (20Gbps (10GHz)/Lane)

3.2.1 Transmission using extremely fine coaxial bundle jumpers: 2 inches, 4 inches, 8 inches, 10 inches

3.2.2 Low loss board transmission: 2 inches, 4 inches

Based on the above measured results, calculate the maximum transmission length for each transmission path with a loss of -7.5 dB (for reference)

At any transmission speed, CABLINE ®- The transmission distance of the VS II ultra-fine coaxial bundle jumper is approximately 2 to 3 times that of using a low transmission loss board.

What does the environmental performance of a connector refer to?

7 月 18, 2023 通过 admin 0 评论

When selecting connectors, we often consider the environmental performance and understanding what it entails. Specifically, what does the environmental performance of a connector refer to?

1.Temperature resistance Currently, the upper operating temperature limit for connectors is 200°C, excluding a few specialized high-temperature connectors, and the lower temperature limit is -65°C. Since connectors generate heat at the contact points during operation, resulting in temperature rise, it is generally recommended that the operating temperature equals the sum of the ambient temperature and the contact temperature.

2.Moisture resistance The intrusion of moisture can affect the insulation performance of connectors and cause rusting of metal components. The conditions for constant damp-heat testing include a relative humidity of 95% and a temperature of +40±20°C, with a minimum test duration of 96 hours as specified by product requirements. Alternating damp-heat testing is even more rigorous.

3.Salt Spray Resistance When connectors operate in environments containing moisture and salt, the metal structural components and contact surfaces of the connectors may undergo electrochemical corrosion, affecting the physical and electrical performance of the connectors. To assess the connector’s ability to withstand this environment, salt spray testing is conducted. This involves suspending the connectors in a temperature-controlled test chamber and spraying them with compressed air carrying a specified concentration of sodium chloride solution to create a salt spray atmosphere. The exposure time is determined by product specifications, typically lasting at least 48 hours.

4.Vibration and Shock Resistance Vibration and shock resistance are important performance characteristics of electrical connectors, particularly in special application environments such as aerospace, railway, and transportation. They serve as important indicators for evaluating the mechanical robustness and electrical contact reliability of electrical connectors.

The above are the four key points of common connector environmental performance criteria. In addition to these, other environmental performance aspects of electrical connectors include sealing capability, liquid immersion, and low pressure resistance.

Introduction to 5 common wiring methods for terminal connectors:

7 月 18, 2023 通过 admin 0 评论

Terminal connectors enable safe, reliable, and efficient electrical connections, and are used in fields such as power electronics, electrical control, and power supply for signal and voltage transmission. Additionally, using terminal connectors for wiring results in a neater appearance and facilitates maintenance in the long run.

There are five common wiring methods for terminal connectors:

1.Insulation displacement connection:

Also known as IDC (Insulation Displacement Connection), it features high reliability, low cost, and ease of use, making it suitable for flat cable connections. In this method, there is no need to strip the insulation layer of the cable. The pointed tip of the “U”-shaped spring contact of the terminal connector pierces the insulation layer, allowing the cable conductor to slide into the slot of the spring contact and be clamped, forming a tight electrical connection.

2.Screw connection:

The screw connection method uses a screw-type terminal block for connections. It is important to consider the permissible maximum and minimum wire cross-sections for the connection, as well as the maximum tightening torque allowed for different screw specifications.

3.Crimping:

 Crimping is a technique used to compress and displace metal within defined limits in order to join wires to contact pairs. A good crimp connection results in the flow and intermixing of metals, causing symmetrical deformation of the wire and contact material. This type of connection is similar to cold welding and offers excellent mechanical strength and electrical continuity, making it suitable for harsh environments. However, crimping is a permanent connection method and can only be used once.

4.Welding:

The most common form of welding is soldering, where the crucial aspect is the formation of a continuous metallic bond between the solder and the surface being soldered. Therefore, for terminal connectors and cold-pressed terminals, solderability is of utmost importance.

5.Wrapping:

Wrapping involves directly winding the wire around the angular post of a contact component. During wrapping, the wire is wound, pressed, and secured at the angular post of the contact component under controlled tension to form an airtight connection.
