What are the common types of electric motorcycle connectors?
Below are common connector types for electric motorcycles and their characteristics, integrating industrial standards, market applications, and technical parameters:
1. Industrial-grade hermetic connectors (e.g., LP20 type)
Features: IP68/IPX9K waterproof rating, 500KPa hermeticity testing, gold-plated contacts for reduced resistance, temperature rise ≤30K, 2000 mating cycles.
Applications: Suitable for charging interfaces, particularly in outdoor environments or high-frequency mating scenarios.
2. 2.8mm Series Connectors
Specifications: Available in 2P/3P/4P/6P/9P configurations, male-female mating design with locking mechanism for waterproofing.
Advantages: Low cost (unit price approx. ¥0.8–¥1.5), widely used for controller and motor harness connections.
3. 6.3mm Series Connectors
Typical Models: DJ7021-6.3-11 (2-pin), DJ7011-6.3-11 (1-pin).
Applications: Power or signal transmission for e-bikes and motorcycles, compatible with ABS plastic.
4. High-Current Fast-Charging Connectors
Design: 2+6-pin configuration (e.g., 80A fast-plug charging/discharging), supports high-power charging.
Case Study: Dedicated waterproof plug for Hello e-bikes, compatible with high-capacity battery packs.
5. Angled/Straight Charging Connectors
Function: Distinguishes installation orientation. Straight connectors suit compact spaces; angled connectors facilitate cable routing.
6. Car Charger Female Connector
Parameters: 12-24V voltage, 10A current, waterproof design for cigarette lighter modification or external power supply.
7. Tire Pressure Monitoring Dedicated Connector
Type: Bluetooth external sensor transmitting data via wireless connector.
Compatibility: Supports standards like GB/T 20234 (China), CHAdeMO (Japanese), Combo (European/American), etc. Note differences between electric motorcycle and electric vehicle connectors.
Summary: Selection should balance current requirements (e.g., 6.3mm or fast-charging for high currents), environmental factors (IP68 for waterproofing), and cost (2.8mm for economical options).
