KR‑220A Servo‑Driven Connector Mating‑Force Analyser
Automatic Connectors Plug Insertion and Extraction Force Test Machine
The Automatic Connectors Insertion Force Testing Machine and Extraction Force Tester is designed for conducting force tests on connectors during insertion and withdrawal. It comes with a unique device that automatically matches with a variety of special fixture connectors to provide accurate force results. All testing information can be set through the computer, and the machine can automatically store testing conditions, test results (load-displacement) curves, and life decay curves and generate reports.

Product Overview
The KR-220A servo-driven plug-pull force testing station is a fully computerized precision test rig dedicated to evaluating mechanical performance of all wiring terminals, charging plugs, industrial connectors and data interfaces. It utilizes closed-loop servo motion control paired with high-precision load cell to capture real-time insertion resistance, withdrawal tension and cyclic fatigue attenuation data during repeated plugging cycles.
Equipped an automatic centering fixture platform and full set of interchangeable clamping jigs, the unit eliminates unilateral force offset that distorts test results. Supporting synchronous dynamic impedance monitoring as an optional upgrade, it delivers complete mechanical + electrical performance reports for connector R&D, incoming QC and factory batch validation. Widely deployed in consumer electronics factories, automotive wiring workshops, new energy harness labs and third-party component certification institutes.
Core Competitive Strengths
- High-Rigidity Servo Motion Framework
Integrated double-column thick steel frame paired with Panasonic servo drive system delivers ultra-stable travel control, speed accuracy within ±0.5%. Max travel reaches 150mm with 0.01mm displacement resolution, maintaining consistent motion track even after hundreds of thousands of continuous plugging cycles, avoiding frame deformation-induced data drift.
- Multi-Range Interchangeable Load Sensors
Six optional load cell configurations (2kg / 5kg / 20kg / 50kg / 100kg / 200kg) cover micro lightweight USB connectors to heavy-duty industrial aviation plugs. Force measurement precision hits ±0.2% FS, supporting free unit switching between N, gf, kgf and lbf for global standard testing requirements.
- Auto Centering XY Multi-Axis Fixture Platform
Dual-direction adjustable sliding base realizes automatic alignment of male & female connector terminals during each plug stroke. Prevents one-sided extrusion wear on pin contacts, ensuring each cycle bears uniform vertical force; multiple dedicated jigs for single pin retention, row terminals and circular aviation plugs are included as standard accessories.
- Windows Intelligent Test Analysis Software
Full bilingual PC control system allows one-click preset of test parameters: travel range, plug speed, cycle count, dwell pause time and upper/lower force tolerance thresholds. The system synchronously generates load-displacement curves and cycle life decay graphs, auto-calculating peak insertion force, minimum pull force and average fatigue loss rate. All raw data, charts and inspection reports can be saved locally, exported to Excel or printed as standard A4 documents.
5.Multi-Layer Safety Interlock Protection
Dual safety mechanisms including hardware overload cutoff and software upper limit stop. When test force exceeds sensor rated load or force value goes outside preset tolerance band during fatigue testing, the machine immediately halts movement to protect the precision load cell and test fixtures, reducing equipment failure loss.
6. Expandable Dynamic Impedance Monitoring Module
Optional real-time contact resistance testing unit links with the main system to record impedance fluctuation synchronously alongside plug force data, ideal for high-end charging plugs, communication connectors and automotive terminals that require simultaneous mechanical and electrical reliability assessment.
Supported Standard Test Projects
- Single-hole male/female connector one-time insertion & extraction force measurement
- Long-cycle plug-pull fatigue life test (up to millions of repetitive strokes)
- Terminal pin retention pull-out force test (single pin plastic holding strength)
- Multi-row flat connector overall plug resistance detection
- Small charging cable, USB, Type-C daily plug force verification
- Aviation circular plug heavy-duty insertion tension test
- Auxiliary tensile & compression performance testing for small plastic parts
- Synchronous contact impedance real-time tracking (with optional module)

Standard Complete Test Operation Flow
- Equipment Connection & Software Startup
Assemble main tester, desktop computer and signal data line; launch the dedicated test program, select matching load cell model according sample load range.
- Fixture Installation & Sample Clamping
Mount corresponding centering jig on the XY sliding platform, lock male and female connector specimens separately on upper/lower clamps, adjust horizontal position for perfect coaxial alignment.
- Test Parameter Configuration
Set plug speed, maximum travel, cycle repetition count, intermediate pause duration and upper/lower force warning limits in the software panel, save parameter template for batch repeated testing.
- One-Click Automatic Plug-Pull Cycle
Tap start button; the servo system executes full insertion → hold dwell → full withdrawal loop automatically, continuously capturing real-time force and displacement data throughout every stroke.
- Curve View & Data Statistics
After finishing designated cycles, browse overlay force-displacement curves and life attenuation charts on screen; the system auto computes max/min/average force and standard deviation of all test cycles.
- Report Export & Machine Shutdown
Export complete test records and graphs to Excel or print official A4 inspection reports; remove test samples, retract the moving slide to origin position, cut off power supply after daily testing.
