From April 13th to 15th, Yongjie New Energy Technology Company attended the Productronica China 2025 in Shanghai. To a matured manufacturer of wiring harness tester, Productronica China is a vast platform which enables manufacturers and users to communicate. It is firstly good for the manufacturers to show off its strength and advantages, also good for the manufacturers to understand users' new demands.
On the exhibition, Yongjie displayed the self-innovated test stations and obtain large concern from interested users. Customers and related users had put forward many questions about technology and operation. They also had passionate discussion on hardware and software.
Test stations on the exhibition are:
H Type Wire Clip (Cable Tie) Mounting Test Stand
First innovated by Yongjie company, flat material barrel is applied to the Cardin Mounting Test Stand. Advantages of the new innovated test stand are:
1. The flat surface enables the operators to place the wiring harness smoothly without any obstacle. The flat surface also provide better view during operation.
2. The depth of material barrels is adjustable according to different length of cable clips. The flat surface concept reduces working intensity and improves working efficiency by enable the operators to access material without lifting their arms.
TAKRA Cable Assembly 6G High-Frequency Test System / 3GHz Ethernet Cable Testing System
This testing system provides precise measurements for the following key performance indicators, ensuring compliance with industry standards for harnesses (including SPE/OPEN Single-Pair Ethernet):
Characteristic Impedance
Propagation Delay
Insertion Loss
Return Loss
Longitudinal Conversion Loss (LCL)
Longitudinal Conversion Transfer Loss (LCTL)
Rubber Component Air-Tightness Test Bench
The air tightness testing system follows a standardized operational sequence: First, securely mount and clamp the test connector in the fixture. Upon initiating the test program, the system automatically enters the inflation phase, precisely pressurizing the chamber until reaching the preset value. The pressure holding test then commences, where the system monitors pressure decay after stopping inflation. After completing the retention period, the system verifies results by comparing measured values against quality standards. For passing units (6A), the system automatically unlocks the fixture, ejects the part, prints a PASS label, and archives test data while displaying a green ✓ PASS indicator. Failed tests (6B) trigger data recording and a red ✗ FAIL alert, requiring administrator authorization for ejection. The entire process features real-time pressure monitoring, automated pass/fail determination, and full data traceability to support quality control protocols.
