Abstract
Abstract A magnetic electrical connector utilizable to complete an electrical connection between an internal combustion engine and a battery includes a pair of hollow sleeves constructed of magnetic material and connected together by a magnet. One of the hollow sleeves is attached to a battery cable while the other sleeve is fixedly secured to one of the battery posts, and a long magnet is then positioned within both of the sleeves to complete the electrical connection. The sleeves may be of any desired shape, such as cylindrical, square and the like, while the connecting magnets will be similarly shaped so as to conformingly fit within the sleeves, and spring arms may be positioned on the sleeves to provide an additional means of holding the magnets in place. Additionally, a magnet may be attached directly to a top mount battery post without the necessity of utilizing a sleeve by drilling a hole through the post into which the magnet may be inserted. The construction of the magnetic electrical connector permits a rapid manual disconnection of a battery without the necessity of utilizing any tools.
