CIRCUIT BREAKER HAVING TERMINAL CONNECTION STRUCTURE IN IMPROVED FORM WITH LOWER HOUSING EDGE PROPERTY BY USING EDGE SHAPE OF LOWER HOUSING INCLUDING STEPPED UNIT ON UPPER PART OF REAR WALL FIN AND C-SHAPED TERMINAL BLOCK

摘要

The present invention relates to a circuit breaker which has a terminal connection structure in an improved form. The circuit breaker includes: upper and lower housings (200); a circuit breaker unit which electrically connects terminals on both sides or cuts the connection; and a terminal connection unit (100) which electrically couples the internal and external terminals (T1, T2) of the circuit breaker unit. The terminal connection unit (100) includes: a hollow terminal block (10) which has a spiral groove (11a) formed on an upper wall unit (11), lets the internal terminal (T1) enter a rear opening unit, and lets the external terminal unit (T2) enter a front opening unit; and a fixing bolt (50) which is inserted and rotated in the spiral groove (11a) and fixes and presses the internal and external terminals (T1, T2) in overlapping positions. The mount groove (210) is formed to mount a terminal block (10) on both sides of the rectangular corners of the lower housing (200). The mount groove (210) is formed by the middle wall (220) of the inner housing and the partition fins of the outer housing.;COPYRIGHT KIPO 2018
