EV Charging Cable Terminal Crimping Machine
An EV Charging Cable Terminal Crimping Machine is a specialized piece of equipment designed for producing AC and DC charging gun cable assemblies. It performs highprecision mechanical crimping to bond cable conductors with terminals, ensuring strong mechanical strength and reliable electrical conductivity—critical requirements for highvoltage EV wiring harnesses.
1. Application Scope
AC charging gun cables
DC highvoltage charging cables
Largegauge multistrand copper cables (16–120 mm²)
EV charging terminals, copper lugs, ring terminals, and customized HV terminals
2. Key Functions
1) Automatic Wire Feeding & Positioning
The clamping system automatically positions the cable, ensuring the conductor is aligned perfectly with the crimping point to prevent miscrimps and weak connections.
2) Intelligent Terminal Feeding
Terminals are automatically arranged, oriented, and delivered into the crimping die—greatly reducing manual handling and positioning errors.
3) HighVoltage Terminal Crimping
Using a servo press or servohydraulic system paired with precision tooling, the machine ensures:
Consistent crimp height
Stable crimp geometry
Pullforce performance that meets UL, QC/T, and customerspecific standards
4) Automatic Quality Monitoring
Crimp height monitoring
Realtime force/pressure curve monitoring
NG detection with automatic stop or reject handling
This ensures every crimp has traceable quality data.
5) QuickChange Tooling
Compatible with various EV charging terminals and designed for fast tooling changeover to minimize production downtime.
3. Advantages
Optimized for largegauge cables and highvoltage terminals (beyond the capability of standard crimping machines)
High consistency with forcecurve monitoring
Easily integrated into fully automated wiring harness production lines
(cutting → stripping → crimping → sealing/assembly → testing)
Simple operation and low maintenance
Full safety protection, including twohand operation and interlock features
4. Typical Applications
EV charging gun manufacturing
Charging cable OEM/ODM production
Highvoltage wiring harness factories
Largegauge power cable terminal processing
