Abstract

The invention discloses a power cord plug leakage prevention device of a server cabinet and a use method thereof, and relates to the technical field of safety protection of the server cabinet. It includes a limit device and a switch device for connecting with an external power cord plug. The limit device includes a power supply and a limit plate connected sequentially from top to bottom, an armature, a first elastic member, and an iron core with a conductive winding. The winding is connected in series with the power supply and the switch device to form a conductive circuit. When the power cord plug of the server cabinet is inserted into the external power cord plug, the switch device changes from the normally closed state to the disconnected state, and the armature is supported by the first elastic member, so that the limit plate blocks The wheels of the server cabinet prevent the server cabinet from moving; when the power cord plug of the server cabinet is unplugged from the external power cord plug, the conductive circuit is connected, and the armature and the magnetized iron core are attracted together, so that the limit plate moves downward and the server The cabinet is in a movable state. The invention can prevent the power cord plug of the server cabinet from being unplugged by mistake.

Description

technical field

[0001] The invention relates to the technical field of safety protection of server cabinets, in particular to a leak-proof device for power cord plugs of server cabinets and a use method thereof. Background technique

[0002] When the server cabinet needs to be tested, the power cord plug of the server cabinet needs to be inserted into the external power cord plug of the external power supply first, so that the external power supply supplies power to the server cabinet.

[0003] During the tester's testing of the server cabinet, the server cabinet is always powered on. Once the test is completed, the server cabinet's power cord plug needs to be unplugged from the external power cord plug before the server cabinet can be moved.

[0004] But after the test to the server cabinet is completed, the tester often forgets to unplug the power cord plug of the server cabinet from the external power cord plug, and just moves the server cabinet. This situation easily cau...

Examples

Embodiment 1

[0040] Such as figure 1 or image 3 As shown in the figure, a power cord plug leakage prevention device for a server cabinet includes a limit device and a switch device.

[0041] Such as figure 1 or image 3 As shown, the limiting device includes a first connecting plate 1 , a second connecting plate 2 , a guide rod 3 , a first elastic member 4 , an armature 5 , an iron core 6 , a conductive winding, and a limiting plate 8 .

[0042] Such as figure 1 or image 3 As shown, the first connecting plate 1 is provided with mounting screw holes 1-1. The lower end of the guide rod 3 is provided with an external thread for threading engagement with the mounting screw hole 1-1. By providing the external thread and the mounting screw hole 1-1, the assembly and disassembly of the guide rod 3 and the first connecting plate 1 can be simplified.

[0043] Such as Figure 5 As shown, the second connecting plate 2 is provided with a guide hole 2-1 for clearance fit with the guide rod 3,...

Embodiment 2

[0065] This embodiment 2 is the same as embodiment 1, the difference is that, as Figure 7 or Figure 8 As shown, the switching device of this embodiment 2 directly adopts the normally closed micro switch 19, which is the prior art, and the working principle of the normally closed micro switch 19 is that when an external force acts on the normally closed When the transmission element 19-1 of the type micro switch 19 is on, the normally closed micro switch 19 is in the disconnected state, so that the conductive circuit is de-energized; when the external force is removed, the normally closed micro switch 19 is in the normally closed state, so that The conductive loop is in a conductive connection state. In addition, the plug 12-1 of the power cord of the server cabinet 12 does not need to be provided with an insertion rod 12-2.

[0066] The normally closed micro switch 19 is directly used, and the installation is convenient. The normally closed micro switch 19 can be directly ...
