Electrical apparatus, in particular an alternator for motor vehicles, having a protector element

摘要

Electrical apparatus, for example an alternator (1) for a motor vehicle, having a cap (3) with an aperture (4) through which an electric power output cable (5) extends for connection with an electric cable (6) which must extend in a predetermined direction (9) from the said terminal (5). This apparatus includes a protector element (10) of electrically-insulating material of substantially annular shape, the wall (11) of which has an interruption (12) which is greater than the section of the aforesaid cable (6), and has at one end coupling elements (13) operable to enable the element to be rotatably mounted in the aperture (4) of the cap (3). The protector element (10) and the cap (3) also have respective engagement means (16, 18). When the protector element (10) is rotated once mounted in the aperture (4), these engage each other and lock the protector element (10) in an angular position in which its interruption (12) is facing the predetermined direction (9) along which the electric cable (6) must extend. <IMAGE>
