AS/NZS 3122:2005 pdf – Approval and test specification—socket-outlet adaptors.
Pins and contacts shall be of suitable corrosion-resisting metal of sufficient rigidity and durability for the intended application.
10.2 Construction
Contacts of any socket portion shall make and maintain, under normal service conditions, satisfactory electrical and mechanical contact with the pins of the appropriate type of plug. For a socket-outlet intended to accommodate plugs with flat pins, contact shall be made with both sides of each pin.
The alignment and contact-making properties of contacts shall be independent of terminal screws.
The effectiveness of the contacts shall be independent of pressure from any thermoplastic or resilient moulding.
In a socket-outlet designed for use with flat-pin plugs complying with ASINZS 3112, the contacts shall be self-adjusting in pitch and contact making.
10.3 Entry or withdrawal of plug pins into a socket-outlet
Within the socket-outlet there shall be provision for effective guidance of the appropriate corresponding plug pins to ensure direct entry and withdrawal without critical distortion of the socket-outlet contacts.
Compliance shall be checked by visual inspection and, if necessary, by manual or electrical test.
10.4 Assembly of pins
If, during assembly, pins can become readily detached from the plug portion while remaining attached to the conductors of a flexible cord, or have to be detached from the plug portion in order that connection can be effected, it shall not be possible for the socket- outlet adaptor to be assembled with any pin located in a position other than that intended to be occupied.
In a socket-outlet adaptor made of resilient insulating material, the pins, contacts and
terminals shall be held securely in position.
11 EXPOSED METAL
A socket-outlet adaptor shall have no exposed metal parts when inserted in an appropriate
socket-outlet.
12 MEANS OF ENTRY AND CORD ANCHORAGE FOR FLEXIBLE CORD
12.1 General
A socket-outlet adaptor having facilities for the connection of a flexible cord shall be provided with a single aperture for the entry of the flexible cord together with any protective covering, and for effective anchorage of any flexible cord which the socketoutlet adaptor is intended to accommodate such that any stress on the terminals will be substantially reduced. For rewirable socket-outlet adaptors, the anchorage shall be effective for the range of flexible cords listed in Table 1 except where—
(a) there is a special aperture for accommodation of only one type or size of flexible cord, a circular hole not being regarded as restricting entry of cords having diameters smaller than that of the hole.
