IEC 60884.1 Test Device To Verify The Fixation Of Pins In The Body Of The Plug Single Station Plug Pin
Standard:
IEC 60884-1 'Plugs and socket-outlets for household and similar purposes – Part 1: General requirements' clause 24.10, Figure 30
Standard description:
The plug is placed on a rigid steel plate provided with holes suitable for the pins of the plug as shown as an example in figure 30.
The distances between the centres of the holes (for example, d1 and d2) shall be the same as the distances between the centres of the circle circumscribed around the cross-sectional area of each pin in the standard sheet of the plug.
Each hole shall have a diameter equal to that of the circle circumscribed around the crosssectional area of the pin plus (6 ± 0,5) mm.
The plug is positioned on the steel plate in such a way that the centres of the circles circumscribing the pins coincide with the centres of the holes.
A pull P equal to the maximum withdrawal force as given in table 16, is applied, without jerks, for 1 min on each pin in turn, in the direction of the longitudinal axis of the pin.
The pull is applied within a heating cabinet at a temperature of (70 ± 2) °C, 1 h after the plug has been placed in the heating cabinet.
After the test, the plug is allowed to cool down to ambient temperature and it shall be verified that no pin has been displaced in the body of the plug by more than 1 mm.
Test sample: Plug, pin
Parameters:
| Test station | 1 station |
| Test weight | 50N*1, 20N*2, 30N*1, 4N*1 |
| Gauges | provide 6A plug gauge, 10A plug gauge, 16 plug gauge, one each |
| Socket | The socket plate should be made according to specific country's plug and socket requirements. |
Application:
It is used for testing the firmness of the plug and the plug pin. The plug is placed on a rigid steel plate provided with holes suitable for the pins of the plug. The distance between the centers of the holes shall be the same as the distances between the centers of the circle circumscribed around the cross-sectional area of each pin in the standard sheet of the plug.
Test Method
1. Before first use, user should familiar with the relevant standards for more effective and proper using the test apparatus and completing the test.
2. The plug is positioned on the steel plate in such a way that the centers of the circles circumscribing the pins coincide with the centers of the holes. Then insert the test plug into the socket in the direction of the longitudinal axis of the pin. After that, the plug is placed in the heating cabinet with temperature (70 ± 2) °C, 1 h after, a pull force is applied inside a heating cabinet
3. Choose the clamping fixture according to the shape of the plug, and make it is firmly connected with the plug (ensure it will not loose when exert a pull force)
4. Choose the pull force weight according to the maximum withdrawal force as given in table 16 (can be achieved by the superposition), the weight is hooked in the ring of the clamp, handle with care, and don’t produce explosive tension.
5. The force is applied on each plug pin for 1 min, after the test, the plug is allowed to cool down to ambient temperature and it shall be verified that the displacement of any plug pin in the plug body should not excess 1 mm.
6. Pay attention to the cleaning of the device and maintenance of the sockets after the test is completed.
