Abstract

An interlock mechanism of a motor, includes a terminal box configured to store a terminal used to connect a power supply cable to the motor; a lid configured to close the terminal box; a fixing member configured to fix the lid to the terminal box; a first connector attached to the lid; a second connector capable of being coupled with the first connector and configured to cover the fixing member in a state that the second connector is coupled with the first connector.

First claim

The invention claimed is:

1. An interlock mechanism of a motor, comprising
a terminal box configured to store a terminal used to connect a power supply cable to the motor;
a lid configured to close the terminal box;
a fixing member configured to fix the lid to the terminal box;
a first connector attached to the lid;
a second connector capable of being coupled with the first connector and configured to cover the fixing member in a state that the second connector is coupled with the first connector.

2. The interlock mechanism of a motor according to claim 1 , wherein
the fixing member is a bolt configured to fasten the lid to the terminal box, and
a distance between the fixing member and the second connector attached to the first connector is shorter than an entire length of the fixing member.

3. The interlock mechanism of a motor according to claim 1 , wherein
the fixing member receives an attachment/detachment tool of the fixing member from a side of the first connector.

4. The interlock mechanism of a motor according to claim 1 , wherein
the lid has an attaching portion to which the first connector is attached.

5. The interlock mechanism of a motor according to claim 4 , wherein
the lid has a plurality of the attaching portions.

6. The interlock mechanism of a motor according to claim 5 , wherein
the number of the attaching portions is greater than the number of the first connector.

7. The interlock mechanism of a motor according to claim 6 , wherein
the attaching portion has a plurality of positions to which the first connector is attached.

8. The interlock mechanism of a motor according to claim 7 , wherein
the number of the positions to which the first connector is attached is greater than the number of the first connector.

9. The interlock mechanism of a motor according to claim 4 , wherein
the lid has a plurality of lid-side attaching portions capable of supporting the attaching portion.

10. The interlock mechanism of a motor according to claim 9 , wherein
the number of the lid-side attaching portions is greater than the number of the first connector.

11. The interlock mechanism of a motor according to claim 4 , wherein
the attaching portion is integrated with the lid.

12. A motor comprising the interlock mechanism of a motor according to claim 1 .

13. An interlock mechanism of a motor, comprising
a terminal box configured to store a terminal used to connect a power supply cable to the motor;
a lid configured to close the terminal box;
a plurality of fixing members configured to fix the lid to the terminal box;
a first connector attached to the lid;
a second connector capable of being coupled with the first connector and configured to cover at least one of the plurality of fixing members from a side of a removing direction thereof in a state that the second connector is coupled with the first connector; and
a plurality of attaching portions to which the first connector is attached, the number of which is greater than the number of the first connector, and which are capable of being integrated with the lid, wherein
a distance between the fixing member and the second connector attached to the first connector is shorter than an entire length of the fixing member, and the fixing member receives an attachment/detachment tool of the fixing member from a side of the second connector attached to the first connector.
