Abstract

Provided is an electronic equipment cabinet capable of detecting a storage state of a circuit board unit by using a smaller number of switches than circuit board units. The electronic equipment cabinet, which stores a plurality of circuit board units inserted and extracted in the same direction, includes a plurality of slots for storing the circuit board units, a plurality of cover members for covering the slots, and a switch for detecting closing of all the slots. The cover members, which are provided by a plurality of types having an installation order restricting mechanism for preventing closing of the slots, except for when the cover members are installed according to a preset installation order, includes a driving member located in a final-installation cover member that is installed last and configured to drive the switch.

Claims (33)

1. An electronic equipment cabinet for storing a plurality of circuit board units inserted and extracted in the same direction, comprises:

a plurality of slots for storing the circuit board units;

a plurality of cover members for covering the slots; and

a switch for detecting closing of all the slots,

wherein the cover members, which are provided by a plurality of types having an installation order restricting mechanism for preventing closing of the slots, except for when the cover members are installed according to a preset installation order, includes a driving member located in a final-installation cover member that is installed last and configured to drive the switch.

2. The electronic equipment cabinet according to claim 1 , wherein the second cover member is removed from the slot by pulling away the first cover member.

3. The electronic equipment cabinet according to claim 1 , wherein the cover members comprise conductive materials.

4. The electronic equipment cabinet according to claim 1 , wherein:

the plurality of types of cover members includes:

the first cover member installed first; and

the second cover member installed while the final-installation cover member is installed after the first cover member has been installed; and

the installation order restricting mechanism includes:

a gasket part abutting on the cabinet and a base abutting on the second cover member, which are formed in the first cover member;

a gasket part abutting on the base of the first cover member and a base abutting on the final-installation cover member, which are formed in the second cover member; and

a gasket part abutting on the base of the second cover member and a base abutting on the cabinet, which are formed in the final-installation cover member.

5. The electronic equipment cabinet according to claim 4 , wherein the gasket parts include gaskets comprising conductive materials.

6. The electronic equipment cabinet according to claim 2 , wherein the cover members comprise conductive materials.

7. The electronic equipment cabinet according to claim 2 , wherein:

the plurality of types of cover members includes:

the first cover member installed first; and

the second cover member installed while the final-installation cover member is installed after the first cover member has been installed; and

the installation order restricting mechanism includes:

a base formed in the first cover member to abut on a gasket part abutting on the cabinet and the second cover member;

a base formed in the second cover member to abut on a gasket part abutting on the base of the first cover member and the final-installation cover member; and

a base formed in the final-installation cover member to abut on a gasket part abutting on the base of the second cover member and the cabinet.

8. The electronic equipment cabinet according to claim 3 , wherein:

the plurality of types of cover members includes:

the first cover member installed first; and

the second cover member installed while the final-installation cover member is installed after the first cover member has been installed; and

the installation order restricting mechanism includes:

a base formed in the first cover member to abut on a gasket part abutting on the cabinet and the second cover member;

a base formed in the second cover member to abut on a gasket part abutting on the base of the first cover member and the final-installation cover member; and

a base formed in the final-installation cover member to abut on a gasket part abutting on the base of the second cover member and the cabinet.
