CABLE SECTION OF ELECTRIC DRILL CURRENT SUPPLY

摘要

A cable section of electric drill current supply includes a contact clutch and a bar made of electric insulating material, those are equipped with contact rings with different diameter; each of those is connected through current-conducting element to a cable wire, and fixed on support elements with cylindrical part connected with respective shell surrounding the node of connection of the cable with current supply elements. Besides that the contact clutch and the bar are made of thermoplastic material, the current supply elements are arranged as continuous current supply metal bars; at that each cylindrical part of the support element is equipped with openings with possibility to fill those with thermoplastic, and each of the shells surrounding the node of connection of the cable with the current supply elements is made of low-pressure polyethylene.
