Background

A rack power outlet (PDU) is a power distribution manager with power distribution and management functions. The PDU power socket is the first path of operation of a plurality of devices and is the most intimate part, and the quality of the PDU directly influences each device. The PDU is mainly used for cabinets in data rooms, data centers and super computing centers, PDUs with different specifications and different functions can be customized according to requirements, suitable power distribution solutions are provided for different power environments, and different standard requirements at home and abroad are met.

The existing cabinet power socket is generally of an integrated structure and comprises a plurality of sockets and a plurality of functional modules, the sockets can be three jacks or five jacks, the functional modules are lightning protection modules, intelligent electric meters, double-break switches and the like, the sockets and the functional modules are sequentially and tightly arranged, three wires (a live wire, a zero wire and a ground wire) are connected to three conductive copper bars in a tin soldering mode, and the sockets and the functional modules are electrically connected through the conductive copper bars. However, defects are easily formed at the welded joint part in the welding process, air holes, cracks and incomplete welding are easily caused, the welded joint is easily dropped in the using process, and the poor welding is a major cause of product defects.

Meanwhile, because the socket areas of the current PDU are of an undetachable structure, the whole PDU is likely to need to be replaced after one socket is damaged, all connecting equipment is stopped, the operation and maintenance cost is high, and especially some servers cannot stop running. In addition, PDU receptacles are thicker and seem heavier than conventional power strips, taking up too much space within the cabinet. In order to prevent the situation that the sockets are not enough, the number of the customized sockets is more than that of the PDU required in the initial stage, waste can be caused, and if the number or the positions of the sockets are not enough, the equipment needs to be detached and reconnected, so that inconvenience in use is caused.

In addition, if the common detachable socket has a fixed rotation direction, but the user often confuses the insertion direction of the socket, which results in the socket not rotating, especially the first time user, may rotate with brute force, which results in the socket being damaged, which is not beneficial to the installation and use of the socket on the rail, while the safety lock is mainly configured to prevent children from taking out the socket, which needs to be pressed to unlock, and then take out the socket rotationally, but it is locked by the way of the pawl snap connection, even if the button is not pressed, the pawl connection may be broken when rotating with slight force, if it is often screwed hard, it may cause complete damage, which may also result in power failure, and it is an automatic locking mode, once the socket is rotated in the power-on direction, it is automatically locked, but in the installation place of the PDU, it may not need to be locked every time, and when the user does not know or forget the existence of the safety lock, the hard screwing condition is caused, the time and the labor are wasted, and the working efficiency is reduced.

If a single track module 1, the socket module 50 and the functional module 40 fails, only the failed module needs to be replaced, so that the operation and maintenance cost is reduced, and the whole PDU does not need to be replaced. Therefore, the bearing frame 20 has a better protection function and a better heat dissipation function for the functional module 40, so that the bearing frame 20 is adapted to more standard intelligent equipment and sensor placing spaces, and elastic installation is realized.

Because the number and the sequence of the plurality of modules of the traditional PDU must be arranged in front, the PDU needs to be designed and customized firstly, and the sequence of the PDU is difficult to change by a client after leaving a factory, the rail-mounted power distribution system of the invention is matched and handed to the client, the client can carry out fancy arrangement on the number and the position of different socket modules 50 at any time and at will in a cabinet, the functional modules in the bearing frame can be customized, so that the bearing frame is convenient to match and assemble, the requirements of customers on different numbers and different sequences of various standard sockets of the PDU are greatly met, meanwhile, variables exist in design and site, and the adjustment needs to be carried out in time, and even if the rail-mounted power distribution system is changed, secondary purchasing is not needed, and similarly, the rail-mounted power distribution system can thoroughly solve the phenomenon that most of client technologies or purchasing personnel mismatch the PDU, thereby greatly avoiding the capital cost of secondary purchasing after client mismatching and simultaneously avoiding the time waste or engineering delay of secondary purchasing.
