4 key points in high current connector design and optimization
Sep 01, 2023
In order to improve the efficiency of the power supply system, designers are often required to increase the density of the overall rack of the power supply on the premise of maintaining system functions, which means higher cooling performance requirements and more Low power loss and other challenges. In order to meet these trends, manufacturers must also ensure that their power connectors have more durable materials and more compact design structures while providing products with high linear current density.
Four key points in power connector design:
Key point one: high compactness
As a leader in the power connector market, DMIC has a series of high-compact power connectors. Xiao Huailong, marketing manager of the enterprise business group of DMIC Global Commercial Products Department, pointed out in the interview that taking the SG50A connector product series as an example, the connector shell material is 2.5 mm thick and can carry a rated current of up to 600 volts. Its connectors are made of high-temperature copper plated with silver. Made of high-quality materials and proven technology to ensure long-term excellent performance and reliability, it is suitable for almost any industry field including communication power supply, medical power supply, industrial power supply, and aviation power supply.
Key Two: Flexibility
In addition to being highly compact,high power connectors must be extremely flexible in design. At this point, DMIC's approach is to combine compactness with excellent current density, such as the SG 50A connector, which adopts snap-on contacts to meet high voltage and high current applications, which is conducive to quick disconnection. The power supply and plug-in and pull-out force are tighter and more convenient, and the modular design allows maintenance personnel to replace each component individually during the process of replacing accessories.
Key 3: Conductivity
Regarding the most important heat dissipation performance of power connections, Huang Yuxiang said that the design of the connector has a direct impact on the conductivity of the power supply, but users cannot completely rely on the connector design to solve conductive problems. In order to optimize the system design, contact terminals are usually divided into two types, one is silver-plated copper and the other is tin-plated copper. The former has better conductivity. All contact terminals of DMIC adopt copper silver plating process.
Key Four: High Efficiency
The power transmission connector has many advantages such as small size, high current, durability, arbitrary assembly, and no male and female. It is a power plug-in that is very worthy of promotion and application. It is very popular in European and American markets, and it is hoped that there will be more domestic industrial applications of this excellent, convenient, safe and universal power plug.
Market opportunities and challenges of power connectors
At the strategic level, DMIC emphasizes that it will devote itself to interconnection products in five key areas in 2023: mobile, industrial, medical, data communication, and automobile. All five sectors represent high-growth markets, both in Asia and around the world. The field of new energy applications has experienced rapid growth in the past few years, and hopes to maintain this momentum. In the future, innovation and quality will also have a strategic position. Interconnect products are highly competitive and are designed and developed to meet the highest standards for unrivaled signal integrity and power integrity.
