UL 2251 Clause 32.1 Charging Gun Pull And Compression Force Test Machine For EV Charging Gun Test

UL 2251 Clause 32.1 Charging Gun Pull And Compression Force Test Machine For EV Charging Gun Test

Applicable Standards and Clauses

UL2251:2022, Clause 32.1–32.2 — Pullout Test

UL2251:2022, Clause 35.1 — Crush Test

Scope, Application, Principle, Structure, and Operating Environment

Specimens and Limitations
Applicable to: Charging gun assemblies

Purpose of the Test
This equipment is designed to evaluate the mechanical strength and reliability of charging gun cable clamping devices through pull and compression tests.
It assesses whether the cable can withstand tensile and compressive forces that may occur during normal use, ensuring structural integrity and durability.

Test Principle
The test system applies linear tensile and compressive forces to the specimen using a motor-driven mechanism.
Both the force value and dwell time can be preset through the touch-screen interface.

Equipment Structure and Features

Integrated dual-column frame with internal stress loading.

Driven by a precision motor and ball screw transmission system.

Equipped with a color touch screen for intuitive operation and digital force display.

Real-time force–time curve display for dynamic monitoring.

Main Components

Touch screen

Force sensor

Compression fixture plate

Tensile fixture plate

Operating Environment

Power supply: AC 220V ±10%, 50–60Hz

Working temperature: 0–40°C

Relative humidity: 30%–90%
