Abstract
The present invention provides a junction box that is divided into a base circuit part connectable to an external circuit and fuse and/or relay connection circuit parts. The junction box includes a base module including the base circuit part, and a fuse module including the fuse connection circuit part and/or a relay module including the relay connection circuit, and the junction box is assembled by combining the modules. The base circuit part of the base module includes rectangular vertical bus bars that are aligned in parallel in an internal part of a case, and the case incorporates multiple terminal housing compartments into which terminals connectable to external wire terminals are inserted, each terminal incorporating pairs of grip ends of terminals that grip and connect to the vertical bus bars.
Claims22
A junction box that is divided into a base circuit part connectable to an external circuit, and at least one of a fuse connection circuit part and a relay connection circuit part, said junction box comprising:
- a base module including a base circuit, said base module including an upper case and a lower case;
- at least one of a fuse module including a case and the fuse connection circuit part having bus bars and a relay module including a case and the relay connection circuit having bus bars said at least one of the fuse module and the relay module being connectable to said base module;
- wherein the base circuit part of said base module is configured with rectangular-shaped vertical bus bars that are aligned in parallel in an internal part formed from said upper case and said lower case;
- and
- wherein an outer surface of one of said upper case and said lower case includes multiple terminal housings into which terminals connectable to external wire ends are insertable, and each terminal includes a pair of terminal grip ends that grip and connect to the vertical bus bars.
A junction box comprising:
- a base module including an upper case and a lower case;
- a plurality of generally rectangular plate-shaped bus bars positioned between said upper case and said lower case, and wherein said bus bars are spaced apart and vertically aligned such that upper and lower longitudinal edges of each said bus bar are positioned adjacent a respective one of said upper case and said lower case;
- and
- wherein an outer surface of at least one of said upper case and said lower case includes multiple terminal housings into which terminals connectable to external wire ends are insertable, said terminal housings being positioned adjacent selected ones of said bus bars so that terminal grip ends of inserted external wire terminals can grip and connect to said vertical bus bars;
- and
- at least one of a fuse module including a case and a fuse connection portion, and a relay module including a case and a relay connection portion said at least one of the fuse module and the relay module being connectable to said base module.
