家禽养殖摘要：An extension cord (2) has an electrical cord (6) with an asymmetrical cross ction (8) and one or more modular sockets (4). The electrical cord has a plurality of electrical conductors (12) extending throughout its length and a plug at one end. The modular socket can be attached anywhere along the length of the electrical cord. The modular socket has two parts (18, 20) forming an opening (44) which hous the cord, the opening being of substantially the same effective asymmetrical cross ction as the cord. When the modular socket is fastened to the cord, spikes (24) in the modular socket pierce the cord's insulating material (26) and contact the conductors running through the cord. The spikes electrically connect the cord's conductors with the plug's electrical contacts (16). The asymmetrical cross ction ensures proper polarity for the modular socket.
