Abstract

A fool-proof housing is configured for a first mounting piece which includes a first fool-proof recess or a second mounting piece which includes a second fool-proof recess to be disposed thereon. The fool-proof housing includes a casing and a fool-proof element. The fool-proof element includes a fool-proof protrusion. The fool-proof element is movably disposed on the casing and includes a first position and a second position. When the fool-proof element is in the first position, the casing is configured for the first mounting piece to be mounted thereon, and the fool-proof protrusion blocks the second mounting piece from mounted on the casing. When the fool-proof element is in the second position, the casing is configured for the second mounting piece to be mounted thereon, and the fool-proof protrusion blocks the first mounting piece from mounted on the casing.

Claims

1. A fool-proof housing, configured for a first mounting piece or a second mounting piece to be disposed thereon, the first mounting piece comprising a first fool-proof recess, the second mounting piece comprising a second fool-proof recess, and the fool-proof housing comprising:

a casing; and

a fool-proof element, comprising a fool-proof protrusion, wherein the fool-proof element is movably disposed on the casing and the fool-proof element comprises a first position and a second position;

when the fool-proof element is in the first position, the casing is configured for the first mounting piece to be mounted thereon, the fool-proof protrusion is located in the first fool-proof recess as the first mounting piece is mounted on the casing, and the fool-proof protrusion blocks the second mounting piece from being mounted on the casing;

when the fool-proof element is in the second position, the casing is configured for the second mounting piece to be mounted thereon, the fool-proof protrusion is located in the second fool-proof recess as the second mounting piece is mounted on the casing, and the fool-proof protrusion blocks the first mounting piece from being mounted on the casing.

2. The fool-proof housing according to claim 1, wherein the fool-proof element further comprises a fixing part, the fixing part comprises a fixing protrusion, and the fool-proof element is disposed on the casing via the fixing protrusion.

3. The fool-proof housing according to claim 2, wherein the casing comprises a first fixing hole and a second fixing hole;
