• Connector evolution to miniaturization: Global giants continue to promote product upgrades, such as TE upgrading 14-bit sealed connectors to 18-bit, using 14 + 4 compact layout, accurately matching the miniaturization of cockpit wiring harnesses and vehicle lightweight requirements, helping to improve vehicle energy efficiency and space utilization. At the same time, domestic enterprises are accelerating breakthroughs in the field of high-frequency and high-speed. The Fakra series connectors of Zhucheng Technology's joint-stock company Deweijia have been equipped with Xiaopeng, Volkswagen Audi and other car companies to support intelligent driving data transmission needs.
Industrial electronics and power tools: extreme environmental adaptability becomes a core competency
The high temperature, high vibration of industrial scenes and the high-intensity operation requirements of power tools have promoted the development of wiring harness products in the direction of "resistance, compliance and customization". This week, a number of technical achievements have targeted to solve industry pain points.

The product adopts special high temperature resistant material, which can withstand high temperatures of 125 ° C. With pre-insulated copper alloy terminals and integrated molding process, it realizes airtight waterproof, anti-vibration and anti-loosening characteristics. Plug and play on site, greatly reducing maintenance costs and the risk of human error.
• Terminal technology innovation: On December 8, WAGO Management Co., Ltd. published the "terminal block" patent (CN121076515A), whose innovative design of the control element can precisely control the switching between the opening and closing positions of the clamping section, improve the reliability and ease of operation of the wire connection, and provide a more flexible solution for industrial equipment wiring harness connection.
• Electric Creative Tools Bundle Benchmark: According to the latest industry research, 76% of power tool downtime is due to wiring harness problems. Companies that meet the new national standard of GB/T 3883.1-2024 gradually highlight their advantages. Among them, Suzhou Kaibaille has become a partner of giants such as Danfoss and Ingersoll Rand with 28 core patents, -50 ° C to 200 ° C temperature resistance range and 500,000 bending life; Qingdao Heavy Industry ranks at the forefront of the industrial Creative Tools bundle market with 120 ° C high temperature sheath and 50A bearing capacity.
Emerging Field Prospects: Humanoid Robots and Low-Altitude Economy Open New Growth Spaces
Although there are no direct new product launches in two major areas this week, the "high density, high reliability and miniaturization" characteristics of the connector harness have become the key to adapting to the core requirements.
In the field of humanoid robots, its joint drive and sensor data transmission require wiring harnesses with extreme flexibility and fatigue resistance. This week's breakthroughs in industrial-grade high temperature resistance and bending resistance technology (such as 500,000 bending resistance wiring harnesses and 125 ° C temperature resistant materials) can be directly migrated and applied to provide support for the stable operation of robot "neural networks". Low-altitude flight equipment faces complex environments such as high-altitude low temperature and strong airflow, which require strict sealing performance of connectors and anti-interference ability of wiring harnesses. The IP67-IP68 protection grade wiring harness and electromagnetic shielding technology (shielding efficiency up to 90dB) released this week have the potential for adaptation. Related companies are accelerating targeted Product Research & Development. In the field of humanoid robots: cable technology has become the core of competition, standard formulation has been accelerated, and the industrialization process of humanoid robots has accelerated, highlighting the strategic value of cables as their "nerves and blood vessels". On December 9, the industry dynamics showed that more than ten robot industry chain companies have been listed in the Hong Kong stock market, of which cable and connector companies account for more than 20%, reflecting the investment heat of the core components track. It is worth noting that the recent results of the first national high-level talent exchange conference on humanoid robot cable technology have been implemented, and the industry has started the revision of the group standard of "humanoid robot cable", which will end the current "fragmentation" status quo of product design and testing, and provide support for domestic enterprises to break through technical barriers. At the technical level, the application of flexible wear-resistant materials such as modified polyurethane and fluoroplastics is becoming more and more extensive, and the signal transmission efficiency of silver-plated copper wire conductors is increased by 30%. The popularity of million bending simulation test technology is promoting the transformation of cables from "static tolerance" to "dynamic adaptation", which is suitable for the joint movement requirements of Tesla Optimus, Utopia Walker X and other models. At the same time, six-dimensional force sensors, as the core components of robot precision operation, demand for supporting wiring harnesses has exploded simultaneously. Each humanoid robot needs to be equipped with 2-4 sets of dedicated signal transmission wiring harnesses. The current localization rate of high-frequency wiring harnesses with anti-electromagnetic interference characteristics has exceeded 50%. It is expected that large-scale matching will be achieved in 2026.
Automotive electronics field: capacity expansion and material upgrading double-line breakthrough, automotive electronic wiring harness production capacity layout and material innovation has become the focus of this week. December 9th news, Jinan Laiwu Tianlai technology photoelectric display module project was completed in November trial production, the municipal key project specializes in planning automotive electronic wiring harness production line, the annual output of 100,000 automotive electronic wiring harnesses, will focus on supporting new energy vehicles intelligent cockpit and autonomous driving system, is expected to add 300 million yuan in 2026, to further improve the regional automotive electronics industry chain. In the field of high-frequency and high-speed connectors, the latest progress of Zhucheng Technology's shareholding company Deweijia has attracted attention. Its Fakra and HSD series connectors have passed the latest model certification of Xiaopeng, Chery and other car companies. Such products can achieve high-speed data transmission of vehicle radar and 5G vehicle to everything. The transmission rate is increased by 40% compared with traditional products. At present, the production capacity is being released at an accelerated pace to cope with the increase in orders. On the material side, the upgrade of new energy vehicles to 800V high-voltage systems has promoted the upgrade of flame retardant demand. The cooperation results between Clariant of Switzerland and Shenzhen Basba have been realized. The high-voltage connector wiring harness with new active flame retardant has been applied in batches. While meeting the UL94 V-0 flame retardant grade, the weight can be reduced by 15%, providing assistance for
From the perspective of industrial collaboration, high temperature resistance and anti-interference technologies in the field of automotive electronics are forming technical interoperability with the field of robotics. For example, the flame retardant material process of automotive high-voltage wiring harnesses has been applied to humanoid robot trunk cables, while the flexible design experience of robot wiring harnesses has fed back to the research and development of moving parts wiring harnesses such as car seat adjustment and door control. Cross-disciplinary technology integration is becoming a new growth point in the industry.
This week's information shows that the connector wiring harness industry is showing three major trends: first, technology focuses on scene adaptation, extreme environmental protection, miniaturization, and intelligence become the core of R & D; second, the rise of domestic power, continuous breakthroughs in equipment manufacturing, patent innovation, and standard setting; third, cross-border integration accelerates, and automotive and industrial technologies extend to humanoid robots, low-altitude economy, and other fields.
