Abstract

A bus bar connector with a replaceable fuse are provided. A first terminal assembly inside the casing includes a first connecting element and plural first resilient contacts electrically connected with the first connecting element. A second terminal assembly inside the casing includes a second connecting element and plural second resilient contacts. An end of the second connecting element is electrically connected with the plural second resilient contacts, and another end of the second connecting element extends to form a cable connecting portion. The first cable assembly includes a first cable body extending from at least one of the left and right sides of the casing, and a cable connection portion connected to one side of the first cable body. The fuse element is connected in series between the cable connection portion and the first connecting element. The second cable assembly is electrically connected to the cable connecting portion.
