A household bus double-pole double-throw circuit breaker live safety replacement base

Abstract

A household bus double-pole double-throw circuit breaker live safety replacement base is disclosed, the structure includes: a circuit break replacement protection box, fixed rail, earthing terminal, housing, and an outer cover, the left side surface of the circuit break replacement protection box and the left end of the fixed rail are flush and are parallel to each other, the fixed rail is fixed to the back plate of the inner wall of the housing by rivets, the outer circumference of the housing is identical to the circumference of the outer cover, the earthing terminal is arranged at the edgeof the shell and the bottom of the rail is fixed. In summary, the invention can not only save labor to separate the conductor from the circuit breaker and avoid injury, but also can protect the chuckand cooperate with the insulation and the electric energy indicator to avoid the danger of electric shock, and at the same time, more fast and firm wiring can be achieved.

Description

technical field [0001] The invention relates to a replacement base for a circuit breaker, in particular to a live safe replacement base for a household bus double-pole double-throw circuit breaker. Background technique [0002] After a period of use, the DPDT circuit breaker of the home bus will generate heat due to the wires under heavy load, which will cause the circuit breaker to loosen the joints, which will cause arcing and burn the contacts. During the replacement process: [0003] 1. Due to the compact structure of the home bus control box, the copper wire and the tin layer plated on the surface of the metal contact are bonded together due to the high temperature in the process of dismantling and pulling out the wire, and inertia is generated at the moment of pulling out The force caused the hand to be bumped and injured. [0004] 2. When aligning the hole position, it is often used to connect the wire to the air switch first and then install the air switch. Nowadays...

[0004] 2. When aligning the hole position, it is often used to connect the wire to the air switch first and then install the air switch. Nowadays, most household main lines use 6-flat copper core wires. The inner copper core has a relatively high hardness. During the opening process, the contacts will become loose when the copper wires are folded and arranged, so it needs to be reinforced twice.
