FUSE BASE CONNECTION TERMINAL APPARATUS

A fuse base connection terminal apparatus comprises a base (1). At least one conductive copper bar (2) is arranged on the base (1). A connection bolt (3) and a connection nut (4) used for selectively connecting to an external cable are arranged in the base. A groove (12) used for mounting the connection nut (4) is arranged under the conductive copper bar (2) on the base. The connection nut (4) is mounted in the groove (12). The connection bolt (3) passes, under the groove (12), through the connection nut (4) and the conductive copper bar (2) sequentially. A top end of the connection bolt (3) extends above the conductive copper bar (2). The apparatus has a simple structure, is convenient and practical, and can provide two different types of cable connection manners, thereby meeting different requirements, saving materials and reducing costs.
