Background technology
In Australia and New Zealand, removable electrical equipment with plug and socket when the rated current of family expenses and similar applications is no more than the extra low voltage of 32A or low-voltage, plug and socket must reach the most basic safety requirements, and its examination criteria is whether the approval of plug and socket and test specification are met the detection requirement among the clause 2.13.9.1 among the AS/NZS 3112:2011.
Stipulate as follows among the AS/NZS 3112:2011 among the clause 2.13.9.1:
2.13.9 the fastness of inserted sheet
2.13.9.1 moving of inserted sheet
By moving of rigidity grip block clamping inserted sheet test inserted sheet, grip block is positioned at apart from plug face 5 ± 0.5mm place, and the power that applies 18 ± 1N is in inserted sheet.The design of grip block should be, and the inserted sheet of not testing during test can not touch grip block.
Except the non-rewirable plug, plug need not connect electric wire during test, and the terminal screw unclamps to allowing the 1mm2 conductor to connect.
The pre-service 1 hour under 40 ± 1 ℃ of temperature of plug and testing apparatus does not apply test force, in the whole test, all parts of plug and testing apparatus all are in this temperature, for all plugs, the point of application be along inserted sheet apart from plug face 14 ± 0.5mm place, the direction of power should be:
(a) along perpendicular to the line on inserted sheet plane and two directions by the inserted sheet center.
(b) reach regulation in (a) along a line with right corner.
10 seconds time, with (a) and (b) described mode power is applied to each inserted sheet gradually, and kept its maximum, force 10 seconds, unclamp then.When applying power, along the deviation of measuring inserted sheet with respect to the line of force of rigidity grip block. maximum deviation should be no more than 2.0mm.
All inserted sheets of test plug were successively tested back 5 minutes finishing last inserted sheet, and its any distortion should not prevent that plug from inserting in the suitable standard tool (not applying undue power).
The bending of plug latch test mainly is to check whether the plug plug blades causes bending being subjected to external force (falling improper use etc. as accident), by after the external force alignment, cause harmful effect to plug blades.If the toughness and the ductility of plug blades metal are not enough, in use, after bending, alignment, cause plug blades to produce fatigue crack or inner structure fracture easily.Particularly, because covering of the insulation course of the outer parcel of latch fails in time to find, will in use cause temperature rise too high because of the contact resistance of breakaway poing is excessive, and then cause the danger of fire, or remain in the socket because of after the plug blades fracture, cause live part to expose and produce the danger of electric shock.
Yet, on the market not without any the special inspecting equipment that meets this standard-required fully, thereby cause this test item of plug and socket to be difficult to the enforcement of simple and fast, not only reduced detection efficiency, testing result also is difficult to reach the requirement of test.
