PURPOSE: A junction box is provided to reduce the size of a housing by inserting connectors from both sides in the width direction. CONSTITUTION: A junction box comprises a main PCB(Printed Circuit Board)(10), a sub PCB(15), lower and upper housings(22,21), and connector headers(30). A plurality of relays(31) and a fuse(32) are arranged in the main PCB. A circuit connecting the relays and the fuse are printed on the main PCB. The sub PCB is perpendicularly connected to the lower middle part of the main PCB. Another circuit connected to the circuit of the main PCB is printed on the sub PCB. The main PCB is installed in the upper inner side of the lower housing. The lower housing supports the sub PCB by the bottom part arranged in the longitudinal direction. Fixing brackets(23) are installed on both sides of the width direction of the upper housing. The upper housing is coupled to the lower housing and supports the parts of the main PCB. The connector headers are installed on both sides of the width direction of the lower housing in order to connect the circuit to the sun PCB. An external connector is connected to the connector header.
