Plug Torque Test Apparatus for Devices Forming a Part of the Main Plug IEC60065 IEC60884-1
1. Introduction
Plug torque test device is designed according to IEC60065 clause 15.4.1 and figure 11, IEC60950-1 clause 4.3.6, IEC60884-1 clause 14.23.2 and etc..It is applied to check the socket outlet 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. Specification
| Distance between contact surface and axis surface | 8mm |
| Force arm | 0-200mm |
| Weights | 2.5N (1 set), 1N (1 set) |
| Configuration | all-purpose plug (1 set, apply to GB and BS plugs),UL plug (1 set) , AS/NZS plug (1 set) |
| Note: other plugs can be customized | |
3. working principle:
Compliance is checked by engaging the device, as during intened 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.
