Referring to fig. 1 to 3, an embodiment of the utility model discloses a fool-proof device for a CRPS power module, wherein the CRPS power module is used for supplying power to a server adapted to the CRPS power module, the CRPS power module comprises a housing 10, the CRPS power module is installed on the server (not shown), the fool-proof device comprises a fool-proof groove formed in the housing 10 and a fool-proof protrusion formed in the server, the fool-proof groove 20 is formed on one side of the housing 10, the fool-proof protrusion 30 is formed at a position corresponding to the fool-proof groove 20 of the server, and the CRPS power module is installed on the server when the fool-proof protrusion 30 is blocked into the fool-proof groove 20.

In the embodiment of the utility model, through the matching of the fool-proof groove 20 arranged on the CRPS power supply module and the fool-proof convex part 30 arranged on the server, when the CRPS power supply module and the server are matched, the fool-proof convex part 30 can be clamped into the fool-proof groove 20, so that the CRPS power supply module can be smoothly installed to the server to realize power supply to the server, when the CRPS power supply module and the server are not matched, the fool-proof convex part 30 can not be clamped into the fool-proof groove 20, and the CRPS power supply module can not be installed to the server, thereby playing a fool-proof role, preventing a user from connecting the unadapted CRPS power supply module and the server by mistake, protecting the server and avoiding damage to the server.

It will be appreciated that the housing 10 of the CRPS power module has a circuit board, electronic components, etc. mounted therein.

Specifically, the housing 10 of the CRPS power module includes a first wall 11 and a second wall 12, the first wall 11 and the second wall 12 being connected vertically; the fool-proof groove 20 is arranged on the first wall 11, the distance from the fool-proof groove 20 to the edge of the first wall 11 is set according to the power supply voltage of the CRPS power supply module, and the server sets the position of the fool-proof convex part 30 according to the required power supply voltage so as to match with the fool-proof groove 20 of the adapted CRPS power supply module. That is, the fool-proof protrusion 30 of the server can only be snapped into the fool-proof groove 20 of the CRPS power module adapted to the server, and cannot be snapped into the CRPS power module which is not adapted, thereby avoiding erroneous connection of the CRPS power module and the server. Wherein, the distance from the fool-proof groove 20 to the edge of the first wall 11 may be the distance from the fool-proof groove 20 to the edge of the side closer to the fool-proof groove 20, and vice versa, the distance between the fool-proof groove 20 and the second wall 12 of the CRPS power supply module with different power supply voltages is defined as the same. It will be appreciated that the housing 10 may include two parallel first walls 11 disposed opposite each other and two parallel second walls 12 disposed opposite each other (only one first wall 11 and one second wall 12 are shown in fig. 1), the two first walls 11 and the two second walls 12 enclose an inner cavity of the housing 10, and the circuit board and the electronic components are disposed in the inner cavity of the housing 10.

When the housing 10 includes two parallel first walls 11 and two parallel second walls 12 disposed opposite to each other, the distance from the fool-proof groove 20 to the edge of the first walls 11 may be the distance from the center of the fool-proof groove 20 to the connection position between the first walls 11 and the second walls 12, or the distance from the connection position between the side of the first walls 11 closer to the fool-proof groove 20 and the second walls 12 to the center of the fool-proof groove 20, or vice versa.

For example, as shown in fig. 2 and 3 (the units of the dimension values marked in fig. 2 and 3 are mm), taking a CRPS power module with a power supply voltage of 12V and 54V as an example, when the power supply voltage of the CRPS power module is 12V, the fool-proof groove 20 is spaced from the edge of the first wall 11 by a first distance, and when the CRPS power module is mounted to a server with a required power supply voltage of 12V, the fool-proof protrusion 30 of the server is snapped into the fool-proof groove 20, wherein the first distance may be 22mm.

In the embodiment of the utility model, the fool-proof protruding part 30 can be convexly arranged at the corresponding position of the inner wall of the chassis of the server and the fool-proof groove 20, when the CRPS power module is installed in the chassis of the server, if the CRPS power module is matched with the server, the fool-proof protruding part 30 is blocked into the fool-proof groove 20, and if the CRPS power module is not matched with the server, the fool-proof protruding part 30 cannot be blocked into the fool-proof groove 20, and the fool-proof protruding part 30 has a certain stopping effect on the CRPS power module, so that the CRPS power module cannot be smoothly installed to the server, and the CRPS power module and the server are prevented from being connected wrongly. Or, the fool-proof protruding part 30 may also be disposed at the power interface of the server, the fool-proof groove 20 may be disposed at a position communicated with the power interface of the CRPS power module, when the CRPS power module is installed in the chassis of the server, the power interface of the server needs to be connected with the power interface of the CRPS power module, if the CRPS power module is adapted to the server, the fool-proof protruding part 30 is blocked into the fool-proof groove 20, and the power interface of the server is smoothly connected with the power interface of the CRPS power module, otherwise, the connection cannot be performed, thereby avoiding the misconnection between the CRPS power module and the server.
