Plug Torque Test Apparatus

Description Plug torque test device is designed according to IEC60065 figure 11 Model PG-PIT

Plug Torque Test Apparatus for Direct Plug-In Equipment

1. Introduction

Plug torque test device is designed according to IEC60065 clause 15.4.1 and figure 11, IEC60950-1 clause 4.3.6, IEC60335-1 clause 22.3, IEC60884-1 clause 14.23.2 and etc.. It is applied to check the main plugs mechanical strength of direct plug-in equipment. A device provided with pins intended to be introduced into fixed socket-outlets shall not impose undue strain on these socket-outlets, the torque shall not exceed 0.25Nm.

2. Working Pricinple

Compliance is checked by engaging the device, as during intended use, with the socket-outlet of a test apparatus. The balance arm of the test apparatus pivots about a horizontal axis through the centre lines of the contact tubes of the socket-outlet at a distance of 8mm behind the engagement face of the socket-outlet.

With the device not in engagement, the balancing arm is in equilibrium, the engagement face of the socket-outlet being in the vertical position.

After the device has been engaged, the torque to be applied to the socket-outlet to maintain its engagement face in the vertical plane is determined by the position of weight on the balance arm, the torque shall not exceed 0.25Nm.
