4N Load Plug Socket Test Equipment Plug Pin Abrasion Tester

Plug Socket Test Equipment Insulation Sleeves Of Plug Pins Abrasion Test Apparatus 

Standard:

IEC 60884-1 2013 ‘Plugs and socket-outlets for household and similar purposes -- Part 1: General requirements’ clause 24.7

Standard description:

Plug pins provided with insulating sleeves are subjected to the following test by means of an apparatus as shown in figure 28.

The test apparatus comprises a horizontally disposed beam, which is pivoted about its centre point. A short length of steel wire, 1 mm in diameter and bent into a U-shape, the base of the U being straight, is rigidly attached, at both ends, to one end of the beam, so that the straight part projects below the beam and is parallel to the axis of the beam pivot.

The plug is held by a suitable clamp in such a position that the straight part of the steel wire rests on the plug pin, perpendicular to it. The pin slopes downwards at an angle of 10° to the horizontal.

The beam is loaded so that the wire exerts a force of 4 N on the pin.

The plug is moved backwards and forwards in a horizontal direction in the plane of the axis of the beam, so that the wire rubs along the pin. The length of the pin thus abraded is approximately 9 mm, of which approximately 7 mm is over the insulating sleeve. The number of movements is 20 000 (10 000 in each direction) and the rate of operation is 30 movements per minute.

The test is made on one pin of each specimen.

Application:

This device is use for test the abrasion resistance strength of insulation sleeve of plug pins

Test sample:

Insulation Sleeve of plug pins.Plug Socket Test Equipment

Feature:

Device consists of a horizontal placement of the beam and the linear movement of the fixture seat, wherein, beam ends with diameter 1mm short steel wire is bent into a U-shaped head (U shape of two vertical fixed on the beam), wire U-shaped bottom is 6mm linear part. Compress the 6mm hemline on the plug insulation sleeve, the motor drives the mounting bolt clamp seat to do reciprocating movement back and forth, conducting the abrasion test to insulation sleeve of plug pins.
