Abstract
A range pole and in-line detachable battery module assembly including a range pole (10) with an elongated tubular graphite-epoxy range pole shell (102) which has a female cap assembly (108) and a male cap assembly (26) at opposite ends. The male cap assembly (26) includes a central bore (30) formed therethrough for containing an insulator plug (32) to which are attached coaxial electrical contacts (132, 134). The coaxial electrical contacts include a first contact surface surrounded by a second concentric contact surface. The male cap assembly includes an externally threaded stud (28) having a central bore (30) formed therethrough for containing an insulator plug (32) to which are attached pin sockets (67, 68) which contain spring-loaded male pin electrical contacts (34, 36). A detachable battery module (12) includes a tubular battery-module shell (24) which has a male cap (26) at one end. The male cap assembly also includes an externally threaded portion having a central bore formed therein for containing an insulator plug to which are attached sockets which contain spring-loaded male pin electrical contacts. A detachable tip (14) includes a ribbed aluminum tip body (150) having e…
