Description

Technical Field

[0001] The utility model relates to the technical field of communication equipment components, in particular to an anti-falling strong and weak electricity integrated intelligent PDU. Background Art

[0002] PDU is what we often call cabinet power distribution socket. PDU is a product designed to provide power distribution for cabinet-installed electrical equipment. It has a variety of series specifications with different functions, installation methods and different socket combinations, and can provide suitable rack-mounted power distribution solutions for different power supply environments.

[0003] Traditional PDUs can only provide power for products in the cabinet. However, with the introduction of intelligent computer rooms, PDUs that integrate strong and weak electricity are becoming more and more accepted by people. By embedding intelligent modules inside the PDU, it is used to receive relevant information in the computer room, such as temperature and humidity, and then adjust the relevant equipment in the computer room accordingly to ensure smooth operation of the relevant equipment in the computer room.

[0004] Whether it is a traditional PDU or a current intelligent PDU, its basic power supply function is still its main function, and the operation of various equipment in the computer room requires long-term uninterrupted power supply, which requires the PDU to be stable when connected to the socket. Generally, the PDU is installed in a cabinet, and there will be fans and other components on the top of the cabinet that will generate slight vibrations when running, forming resonance. When the PDU works in this long-term resonant environment, the connection between the plug and the PDU will loosen, resulting in loose connection and poor contact. Therefore, it is necessary to improve some structures of the plug and PDU to deal with this situation. Utility Model Content

[0032] In order to solve the problems existing in the related prior art, the utility model proposes an anti-falling strong and weak electricity integrated intelligent PDU. The principle and structure of the utility model are described in detail below with reference to the drawings and embodiments.

[0033] Embodiment 1

[0034] See also Figures 1 to 4, the present utility model proposes an anti - shedding integrated intelligent PDU for strong and weak electricity, which includes a housing 1, a socket board 3, sockets 2 and plugs 4 corresponding to the sockets. The overall cross - section of the housing 1 is in a "U" shape, and the socket board 3 is embedded and installed. Specifically, the housing 1 includes a bottom plate and side plates. The side opposite to the upper opening direction of the housing 1 is the bottom plate, and the two sides are side plates. The bottom plate and the side plates are of an integrated aluminum alloy structure. On the inner sides of the upper parts of the two side plates, there are chutes 6. The socket board 3 is arranged in the chutes 6 and can slide relatively in the chutes 6. The plugs 4 and the sockets 2 are of a mother - and - son type plug - socket. The socket 2 is fixed on the socket board 3. The socket specifically includes a convex seat 2a, and on the convex seat 2a, there are jacks 2b. The overall shape of the convex seat 2a is rectangular, and both sides of one long side are chamfered structures, that is, the cross - section of the convex seat 2a is a rectangle with chamfers at two corners. At the same time, there is a recessed groove 2c on the long side without chamfers. The convex seat 2a is an embedded type, and its upper part is flush with the upper surface of the socket board 3. And a plug - in groove 2d is formed on the side of the socket board 3 and the socket 2, and the plug - in groove 2d surrounds the convex seat 2a. Adjacent two sockets 2 form a group, and the chamfered sides of the two sockets 2 in a group are arranged in a staggered manner, that is, the chamfered sides of the two convex seats 2a in a group face each other and are staggered. In this way, on the one hand, it ensures that adjacent two sockets can be normally plugged with plugs, and at the same time, the staggered arrangement can ensure that more sockets can be arranged on the same socket board 3. There are cable tie holes 5 on the socket board 3, and the cable tie holes 5 are correspondingly arranged on the side of the socket 2. The plug 4 includes a plug body 4a, pins 4b and a plug cover 4c. The shape of the plug cover 4c is the same as that of the plug - in groove 2d. At the position corresponding to the recessed groove 2c on the plug cover 4c, there is a spring piece 4d. Specifically, the spring piece 4d includes a limit protrusion 4da and a pressing head 4db. In the plug - in groove 2d, there is a card slot 2e corresponding to the limit protrusion 4da. On the side of the plug cover 4c, there is a connecting ear 4e, and the position of the connecting ear 4e corresponds to the position of the cable tie hole 5.

[0035] The specific working principle is as follows: When in use, the PDU is installed on the cabinet. Generally, the PDU has two installation methods, vertical and horizontal. Here, taking the vertical installation of the PDU as an example, the PDU is installed on the side of the cabinet. The sockets correspond to the various components in the PDU, and the plugs 4 correspond to the various components that need electricity. When it is necessary to plug the plug 4 into the socket 2, the plug cover 4c can be directly pressed and inserted into the plug - in groove 2d. At this time, the limit protrusion 4da of the spring piece 4d will snap into the inside of the card slot 2e, which can prevent the plug 4 from falling out of the socket 2. When it is necessary to replace the plug, by pressing the pressing head 4db, the limit protrusion 4da is separated from the card slot 2e, and then it can be pulled out. When the connection is determined and the device is running normally, at this time, the cable tie is passed through the cable tie hole 5 and the connecting ear 4e, which can further improve the connection effect.

[0036] Please refer to Figure 2 and Figure 5, reinforcement grooves 7 are provided on the inner sides of the side panels, and the shell 1 is spray-painted and insulated as a whole. An insulating sheet 8 is provided inside the shell 1. The insulating sheet also includes side panels and bottom panels. The flame retardancy of the material used reaches UL94V-0 level. Generally, the PDU shell needs to be insulated, which can be completed by spraying insulating paint or other related insulating means to meet relevant national standards. At the same time, an insulating sheet 8 is installed between the conductive part and the shell inside the socket to further ensure insulation. At the same time, the insulating material is required to have a certain flame retardant effect. Here, the insulating sheet uses UL94V-0 grade plastic as raw material.

[0037] Please continue reading Figure 1 The PDU also includes a weak current module 9, which specifically includes a liquid crystal display 9a, a menu button 9b, a network interface 9c and a plurality of sensor interfaces 9d. The sensor interface 9d is respectively connected to a temperature sensor 10, a smoke alarm 11, a door magnetic sensor 12 and a water immersion sensor 13. The application of this weak current module is a conventional application in this industry. Here, the weak current module 9 adopts a hot-swappable structure to facilitate the replacement of the module, so that different customers can choose different weak current modules. After completing the hot-swap, it is fixed through two screw holes.

[0038] At the same time, a master control switch 14 is installed at the end of the PDU. The master control switch 14 is a miniature circuit breaker or an overload protection switch. When overloaded, it can be automatically cut off to ensure the safety performance of each device in the cabinet.

[0039] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
