High current connectors are widely used in solar photovoltaics, UPS power supplies, distributed energy storage, medical equipment, and advanced equipment.

Mr. Song Shiqiang from Kinghelm introduced that in recent years, with the rapid development of industries such as new energy vehicles, 5G communication, charging stations, and cloud computing, the demand for high current connectors and wiring terminals has significantly increased.

According to statistics, the market share of “Kinghelm” high current connectors is rapidly increasing! “Kinghelm connect the world”. Since its establishment in 2007, Shenzhen Kinghelm Electronics Co., Ltd. (www.kinghelm.net) has been dedicated to the design, manufacturing, sales, and technical solutions of RF Rx/Tx antennas, RF wired connectors, and interconnection system products.

The technical backbone of the company comes from Tsinghua University and University of Electronic Science and Technology of China, and has attracted overseas talents. Kinghelm's team keeps up with the times. With existing laboratory instruments, factory equipment and facilities, R&D technicians and production teams have built a new product line to produce high current connectors and related wiring terminals. Mr. Song Shiqiang stated that the company's high current connectors have the advantages of fast matching, easy connection and disconnection, and can be used friendly in installation, testing, and maintenance sites.

Song Shiqiang mentioned that in order to stand invincible in competition, one must have foresight and develop products with targeted strategies. The development direction of high current connectors is towards micro assemblies with small size and large current capacity.

Therefore, Kinghelm has always placed great emphasis on material selection, design, and processing. The wires are made of pure copper with good conductivity. In order to ensure a tight connection between the connecting wire and the terminal, stable pressure is applied to the terminal, thus achieving a large-area reliable connection between the wire and the terminal with sufficient force.

Contact pressure is one of the key technologies for high current connectors. Insufficient contact pressure can cause the wire to shift from the terminal, resulting in increased contact resistance and potential heat oxidation. A clean and substantial contact surface is also crucial in the conductive interface of high current connectors.

When introducing connectors, Song Shiqiang mentioned that the structural components of connectors include conductors, insulators, casings, and accessories. Insulators, commonly known as bases or sockets, are responsible for arranging contacts in the required positions and spacing to ensure insulation performance between contacts and between contacts and the housing. Good insulation resistance, voltage withstand capability, and ease of processing are fundamental requirements for selecting insulation materials. The shell serves as a protective cover of the connector, providing mechanical protection for the internal insulation mounting plate and pins inside, aligning the plug and socket during insertion, and securing the connector to the device. Connector accessories are divided into structural accessories and mounting accessories. The structural accessories include retaining rings, locating keys, positioning pins, guide pins, link links, cable clamps, seals, gaskets, waterproof rings, etc. The mounting accessories include screws, nuts, bolts, spring rings, heat shrink tubing, and so on.

The Kinghelm team (www.kinghem. net) discovered a few years ago that the development of smart hardware products would move towards lighter, higher performance, more functional, and longer-lasting. This trend would require connectors to have smaller dimensions, wider operating frequencies, and higher transmission speeds, leading to a significant increase in sales of Kinghelm's FPC/FFC small flexible connectors. Digital cameras, digital camcorders, car satellite positioning devices, LCD TVs, laptops, etc., extensively utilize FPC/FFC connectors, especially in the communication field like smartphones.

Board-to-board connectors directly connect the power and signals between printed circuit boards (PCBs) through pins, effectively simplifying applications that require PCB stacking. In recent years, there has been a trend towards increasingly smaller sizes, further expanding the market for Kinghelm's board-to-board connectors. These connectors can be used in smartphones, tablets, sports DVs, dash cams, car navigation systems, PDAs, smart homes, video doorbells, laptops, security cameras, camera modules, digital cameras, printers, scanners, medical equipment, TVs, video phones, POS machines, monitoring and communication systems, and computer peripherals.

In recent years, China's connector industry has achieved an annual growth rate of 13%, surpassing the global growth rate of 8% during the same period. The production focus of global connectors has also shifted to China, where a relatively complete industry chain and ecosystem have been established. China is actively promoting the construction of the core network for 5G infrastructure, with related optical fiber cables and distribution equipment being the first to benefit. This trend is expected to lead to an increasing demand for connectors.

Kinghelm Electronics has benefited from the improvement in China's connector manufacturing capabilities. After solidifying its position in the market for microwave antenna RF cables, the company has been progressively expanding its investment in research and development as well as production in the connector market, making it one of the most promising connector enterprises.

Kinghelm has obtained multiple invention patents and has acquired ISO9001 certification, as well as RoHS and REACH certifications. The company is in the process of applying for IATF16949 automotive quality system certification, UL, TUV, and Dun & Bradstreet certifications. Slkor Micro Semiconductor(www.slkoric.com), invested by Song Shiqiang, produces a range of products including diodes, transistors, power devices, and power management chipsets. In recent years, it has also launched new products such as Hall sensors, ADC, and BMS. Together with Kinghelm Electronics, it provides supplementary services to electronic equipment original manufacturers and has become a partner with over 15000 companies worldwide!
