Who Is Konnra Electronics?
Dongguan Konnra Electronics Co., Ltd., known in the market under the brand name KONNRA, was founded in 2004 and has operated for more than twenty years as a connector research, development, production, and sales enterprise. The company is recognized as a High-Tech Enterprise and has built a business footprint that spans North China, Southwest China, Central China, East China, and South China, supporting global connection solution needs. Konnra’s strategic positioning centers on combining technology innovation with market expansion to create value for customers, create opportunities for employees, and create contributions to society.
The company’s work addresses a well-documented set of industry pain points: connector users need dependable connections in harsh environments, including high and low temperatures, humidity, vibration, and coastal or cold climates. Buyers also contend with long delivery cycles, strict quality traceability requirements, constraints on imported part availability, and application scenarios where standard connectors simply cannot be used. Konnra’s operating model is structured around solving these specific challenges.
A Vertically Integrated Manufacturing Ecosystem
One of Konnra’s clearest differentiators is its vertically integrated ecosystem, which covers molds, automation, injection molding, stamping, assembly, CCD inspection, and wiring harnesses under one operational umbrella. This integration allows the company to maintain automation coverage of 95% or more across its production lines and to output a complete connector sample set within 45 days. For automotive connector series specifically, Konnra applies 100% CCD visual inspection, a quality control measure that reflects the stringent demands of vehicle electronics applications.

Konnra operates multiple production bases nationwide, each prestocking key materials based on market demand to shorten order delivery cycles. The headquarters and connector/wiring harness production base in Dongguan Wangniudun spans 30,000 square meters and employs more than 350 people. A dedicated wiring harness production base in Dongguan Changan covers 10,000 square meters with more than 150 employees, while a third wiring harness facility in Hunan Daoxian occupies 2,600 square meters with more than 100 employees. Beyond these, the company maintains entities including Beijing Konnra Hongmao Electronic Technology Co., Ltd. in North China, Chongqing Konnra Electronics Co., Ltd. in the Southwest, Hunan Konnra Electronics Co., Ltd. in Central China, Shanghai Konnra Electronics Co., Ltd. and Kunshan Kangchuang Connector Co., Ltd. in East China, and Dongguan Konnra Precision Technology Co., Ltd. and Daoxian Konnra Electronics Co., Ltd. as additional production bases. Altogether, the company employs more than 600 people, with approximately 10% dedicated to research and development.
Technical Capabilities and R&D Strength
Konnra’s technical foundation rests on more than 20 years of connector R&D experience and more than 50 connector R&D patents. The company invests 5.6% of its total turnover into research and development, supported by a team of 30 R&D personnel. Its technology platform includes precision mold design and manufacturing, automation design and manufacturing, precision injection molding and stamping, a CCD testing center, reverse analysis, R&D design, mold manufacturing, functional testing, and CAE analysis software including Ansys 2022 R1.
These capabilities translate into measurable engineering outcomes. For example, finite element analysis on a 63A connection using 16mm² copper wire shows a maximum temperature rise of 27.3 K, demonstrating the company’s capacity to validate thermal performance before products reach the field. Konnra also performs contact nonlinear analysis, material nonlinear analysis, motion simulation, thermal field analysis, and high-frequency analysis as part of its standard engineering toolkit.
On the quality side, Konnra operates a CNAS laboratory equipped with more than 45 sets of precision testing equipment. Its visual inspection system achieves 95% full intelligent CCD inspection coverage, built on imported Mitsubishi and Panasonic PLC control systems, FA25-35mm optical lenses, 5-megapixel cameras, and dedicated visual inspection software. This infrastructure supports order-driven lean production, full-process quality traceability, and real-time data analysis.
Comprehensive Product Portfolio
Konnra’s catalog totals 69 products and services organized into nine series. The Automotive Connector Series, including products such as ST2H, KR1507, KR2017, KR2021, KR2022, KR2023, KR2026, and KR2203, is engineered for vibration resistance and high-temperature resistance, serving automotive lighting, on-board devices, ECU, and BMS applications. The Power Tool Connector Series, featuring KR1000, KR1259, KR2027, KR2557, and KR3967, is designed for high current-carrying capacity and impact resistance, supporting equipment such as smart lawn mowers, pool cleaning robots, and floor scrubbers.
The New Energy Storage Connector Series, with products like KR1506, KR2004, KR2005, KR2012, KR3000, QK000005, and KRQK001001, is built for high-temperature, low-temperature, and high-humidity environments common in energy storage equipment, outdoor power supplies, and charging piles. The Industrial Connector Series, including KR1256, KR2516, KR2548, KR4200, KRQK000015, and circular connectors, targets Industry 4.0, smart manufacturing, and heavy machinery with vibration resistance, dustproof and waterproof performance, and corrosion resistance.
Additional series round out the portfolio: the Networking & Information Equipment Connector Series (KR0800, KR0803, KR1201, SMA, FAKRA) supports server racks, routers, and data transmission; the Medical Device Connector Series (KR1200, KR1252) serves medical imaging and monitoring equipment with an emphasis on safety and anti-interference performance; the Consumer Electronics Connector Series (KR1005, KR1250, KR1253, KR1500, KR1501, KR2001, KR2501, KR2502) addresses smartphones, wearables, and drones with slim, durable, high-speed connections; and a General Connector Series of more than 20 part families provides standard wire-to-board and board-to-board solutions cross-referenced against JST, HIROSE, Molex, and YEONHO part numbers. A seven-category Wiring Harness Series spans automotive, energy storage, power tool, medical, industrial automation, consumer electronics, and photovoltaic applications.
This cross-reference capability is particularly notable: by aligning its connector families with established JST, HIROSE, Molex, and YEONHO part numbers, Konnra positions its domestic replacement connector series as practical alternatives to imported parts, directly addressing the import-availability pain point many buyers face.
Industry Applications and Customer Validation
Konnra’s connectors and wiring harnesses serve new energy vehicles, new energy storage, industrial equipment, data centers, consumer electronics, smart home products, medical devices, automotive systems, home appliances, power tools, photovoltaics, and networking equipment. In 2025, the company recorded sales of RMB 310 million, with connectors accounting for 60% of the mix and wiring harnesses 40%. Within that total, new energy vehicle lighting sales reached RMB 120 million with a shipping quantity of 400 million pieces, and monthly production capacity reached 150kk.
The company counts global cooperative clients such as BYD, Volkswagen, and DJI under its Win-Win Cooperation strategy. Real-world examples illustrate how Konnra resolves specific technical challenges. The KR2017 connector, for instance, was developed to address a documented pain point: connectors in coastal and cold areas are prone to breakage. Through a material technology improvement, Konnra enabled KR2017 to perform in these harsh environments while maintaining low cost and stable performance, offering a domestic replacement for imported parts. In another case, the KR2026 connector was jointly developed with a customer facing a unique application scenario where standard parts could not be used. Close development alignment between Konnra and the customer ensured smooth project rollout, and the customer received a forward-looking plan for next-phase cost reduction.
