As an enterprise focusing on the R&D and production of terminals and connectors, Guangdong Deke Electric provides key core component support for various wire harness processing scenarios with its high-precision terminal products and highly adaptable connector solutions. Its products are deeply integrated with wire harness processing technologies, serving a wide range of industrial fields and ensuring the reliability, safety, and efficiency of electrical connections.

I. Automotive Industry: A Core Application Scenario for Wire Harness Processing

      Automotive wire harnesses are the "neural network" of automotive electrical systems, undertaking the key roles of power distribution and signal transmission. Their processing quality directly affects vehicle driving safety and functional stability. In the automotive industry, wire harness processing mainly covers the following segmented scenarios:

1. Power System Wire Harnesses : Used for connecting core components such as engines, gearboxes, and power batteries (for new energy vehicles), they need to withstand harsh environments including high temperatures (-40℃~150℃), vibrations (frequency: 10-2000Hz), and oil contamination. During processing, high-temperature-resistant wires (e.g., cross-linked polyethylene wires resistant to 150℃) and Deke Electric’s high-temperature-resistant terminals (made of brass H62 with tin/silver-plated surfaces, temperature resistance rating up to 180℃) are adopted. Precision crimping technology (crimp height tolerance: ±0.05mm) ensures stable current transmission. For example, the crimped part of a single terminal in the power battery wire harness of a new energy vehicle can carry a current of 30-300A, meeting the overall vehicle power demand.

2. Body Control System Wire Harnesses : Covering the transmission of control signals for components such as doors, seats, sunroofs, and lights, these wire harnesses need to be miniaturized and lightweight. During processing, small-diameter wires (wire diameter: 0.3-0.8mm²) and Deke’s micro-connectors (e.g., board-to-board connectors with pitches of 2.0mm and 1.25mm) are used. Automated cutting-crimping-assembly production lines achieve a wire harness error control within ±1mm, adapting to the compact installation space of the vehicle body. For instance, a door wire harness can integrate 15-30 terminal joints to simultaneously transmit multiple signals for window lifting, door lock control, and rearview mirror adjustment.

3. Intelligent Driving Wire Harnesses : Used for connecting intelligent components such as millimeter-wave radars, lidar, cameras, and domain controllers, they need to meet the requirements of high-speed signal transmission (transmission rate ≥10Gbps) and electromagnetic interference (EMI) resistance. During processing, shielded wires (double-layer shielding with aluminum foil + braided mesh) and Deke’s shielded connectors (shielding effectiveness ≥80dB@30MHz-1GHz) are adopted. Impedance matching design (characteristic impedance: 50Ω/100Ω) ensures delay-free data transmission. Currently, the processing qualification rate of mainstream intelligent driving wire harnesses has reached over 99.8%, ensuring the accurate decision-making of autonomous driving systems.

II. Industrial Automation Field: Stable Guarantee for Wire Harness Processing

      Industrial automation equipment has extremely high requirements for the stability and anti-interference performance of electrical connections. As the connection carrier between equipment and components, wire harnesses need to adapt to complex industrial environments in factories (dust, humidity: 30%-90%, mechanical impact). The terminals and connectors of Guangdong Deke Electric, with their high protection level (IP65/IP67) and high mechanical strength (plug-in life ≥5000 times) design, provide reliable support for industrial wire harness processing. The main application scenarios include:

1. Machine Tool Equipment Wire Harnesses : Used for connecting the spindle control, servo motor drive, and tool change system of CNC machine tools and machining centers, these wire harnesses need to be oil-resistant and mechanical wear-resistant. During processing, oil-resistant polyvinyl chloride (PVC) wires and Deke’s oil-proof terminals (nickel-plated surfaces, oil resistance level in line with ISO 1817 standard) are used. The tensile force at the terminal crimping part is ≥50N, ensuring no detachment under high-frequency vibrations of machine tools (amplitude ≤2mm). For example, the spindle control wire harness can achieve 0.1ms-level signal response, ensuring machine tool processing accuracy (error ≤0.005mm).

2. Robot Wire Harnesses : Serving the joint drive and sensor signal transmission of industrial robots (6-axis robots, collaborative robots), these wire harnesses need to have high flexibility (bending life ≥1 million times) and torsion resistance. Flexible silicone wires (bending radius ≥5 times the wire outer diameter) and Deke’s high-flexibility connectors (with elastomer material housings, bending resistance ≥500,000 times) are used in processing. The wire harnesses have high integration and can stably transmit signals under the 360° rotation condition of robot joints. Currently, the signal transmission error rate of mainstream industrial robot wire harnesses is ≤0.001%.

3. Automated Production Line Wire Harnesses : Used for connecting production line conveyors, sorting equipment, and PLC control systems, they need to realize collaborative communication among multiple devices. During processing, multi-core cables (core count: 4-32 cores) and Deke’s industrial connectors (e.g., M12, M8 series connectors with IP67 protection level) are adopted. Standardized interface design enables quick plugging of wire harnesses (plugging time ≤10s), reducing the downtime for production line maintenance. By optimizing the wire harness processing scheme, a certain auto parts production line has reduced equipment failure rate by 30% and increased production efficiency by 15%.

III. New Energy Field: Efficient Adaptation of Wire Harness Processing

      The new energy industry (photovoltaics, energy storage, charging piles) has strict requirements for high current and high safety of electrical connections. Wire harness processing needs to focus on the core demands of "low loss, leakage prevention, and high temperature resistance". Guangdong Deke Electric’s high-current terminals (maximum current-carrying capacity: 800A) and waterproof connectors (IP68 protection level) provide key component support for new energy wire harnesses.

Waterproof sealant (anti-aging life ≥25 years) is applied at the wire harness joints to ensure the long-term stable operation of the photovoltaic system. The wire harnesses of a 100MW photovoltaic power station have a failure rate of less than 0.5% after 5 years of operation, and the power generation efficiency remains stable.

2. Energy Storage System Wire Harnesses : Used for connecting energy storage battery packs, PCS (power conversion systems), and BMS (battery management systems), they need to have overcurrent protection and short-circuit prevention functions. Flame-retardant wires (flame retardant level: UL94 V-0) and Deke’s energy storage terminals (with anti-misplug structure, insulation housing flame retardant level: V-0) are used in processing. The wire harnesses pass the short-circuit test (withstanding 10 times the rated current for 1 second without fusing). The wire harnesses of a 2MWh energy storage system in an energy storage power station can realize stable transmission of charging and discharging current of 200A, and the temperature difference of the battery pack is controlled within 5℃.

3. Charging Pile Wire Harnesses : Used for connecting DC charging piles, AC charging piles, and electric vehicles, they need to meet the requirements of high-current fast charging (DC fast charging current: 200-600A) and electric shock prevention. High-conductivity wires (copper purity ≥99.95%) and Deke’s charging pile-specific connectors (in line with GB/T 18487.1 standard, with anti-misplug and anti-leakage protection) are used in processing. A cooling system is adopted at the wire harness plug (e.g., liquid-cooled wire harnesses, which can withstand 600A current with a temperature rise ≤30K). Through the liquid-cooled wire harness processing scheme, a certain ultra-fast charging station realizes charging an electric vehicle to 80% in 10 minutes, increasing charging efficiency by 40%.

IV. Consumer Electronics Field: Miniaturization Innovation in Wire Harness Processing

      Consumer electronics (smartphones, laptops, smart home devices) tend to be "thin, light, and miniaturized".
