The plurality of insulating parts 143 may include first insulating parts 143a to 143c to correspond to the first to third connection holes.

Hereinafter, the fastening method of the vacuum circuit breaker 100 will be described in detail.

The assembler fixes the support member 120 by screwing the first housing 110. At this time, the assembler fastens the first connection terminal 131 to the third connection terminal 133 to the support member 120. In addition, the assembler fastens the vacuum interrupter to the support member 120.

On the other hand, when the above process is completed, the assembler arranges the second housing 140 so that each sliding part 141 corresponds to each guide groove 121a.

The assembler slowly exerts force on the second housing 140. At this time, each sliding part 141 is inserted into each guide groove 121a and slides. Each sliding part 141 is fastened by sliding in each guide groove 121a.

On the other hand, when the assembler continues to apply force to the second housing 140, one end of the second housing 140 is close to the support member 120. At this time, each engaging projection 142 is inserted into each engaging projection fastening groove 121b.

If the assembler continues to apply force, each locking projection 142 is completely inserted into the locking projection fastening groove 121b is fixed. Therefore, the second housing 140 and the support member 120 are firmly fastened.

Meanwhile, when the second housing 140 and the support member 120 are fastened and fixed, the first connection terminal 131 is exposed to the outside through the first connection hole. At this time, the first insulation part 143a surrounds the first connection terminal 131 and protects it from the outside. In addition, the first insulating part 143a prevents an external user from contacting the first connection terminal 131 to promote safety of the user.

The second insulation portion 143b and the third insulation portion 143c are also formed in the same manner as the first insulation portion 143a and play the same role.

Accordingly, the vacuum circuit breaker 100 prevents the second housing 140 from being fastened to the support member 120 to expose the first connection terminal 131 to the third connection terminal 133 to the outside. In addition, the second housing 140 prevents an arc, etc. generated inside the first housing 110 from being discharged to the outside.

The vacuum circuit breaker 100 may secure the safety of the external user by separating the inside and the outside of the second housing 140.

As described above, embodiments of the present invention have been described, but a person having ordinary knowledge in the technical field may add, change, delete, or add a component within the scope not departing from the spirit of the present invention described in the utility model registration claims. The present invention may be variously modified and changed by addition, etc., which will also be included within the scope of the present invention.
