Detailed Description

The following description of the exemplary embodiments of the present application, taken in conjunction with the accompanying drawings, includes various details of the embodiments of the application for the understanding of the same, which are to be considered exemplary only. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present application. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

The industrial connector is used as an important node for connecting the cabinet and the power distribution cabinet, and the safe and reliable operation of the industrial connector is very important. The industrial connector is easy to loose or fall off the connection between the cable and the industrial connector in the long-term use process. If the industrial connector is loose, the operation of the cabinet can be seriously influenced, and even a circuit can be burnt out and other serious consequences can be caused. Industrial connectors are electrical connections which do not have corresponding monitoring devices installed, so that the loosening of the industrial connector is not noticeable and cannot be dealt with immediately.

The electrical connection reliability of the industrial connector can be checked by operation and maintenance personnel in modes of thermal imaging scanning and the like, and the connection condition of the industrial connector cannot be monitored in real time. Or, in the power failure process, the industrial connector is manually fastened, and the power failure operation can cause the equipment to be electrified in a single way, so that the usability of the equipment is reduced.

Industrial connectors of data centers are used in huge quantities, and for example, 100000 servers require 2500 to 4000 cabinets, and the cabinets are generally supplied with power in two ways, so that 5000 to 8000 industrial connectors are required for 100000 servers. If the connection reliability of the industrial connector is detected manually, the workload is huge.

In addition, manual inspection does not have real-time performance, and poor connection of the industrial connector can be found only in periodic inspection or maintenance work. Moreover, the power supply equipment needs to be powered off and isolated due to the fact that power is regularly and firmly cut off, the load of the data center is important, and the usability of the data center is reduced due to the fact that power is cut off and isolated.

Be provided with the cavity that is used for holding external cable in the fastening buckle 4, external cable 1 inserts in the cavity of fastening buckle 4, revolves wrong fastening bolt 2 for fastening bolt 2 compresses tightly external cable 1, and thus, external cable 1 is fixed in fastening buckle 4 through fastening bolt 2. Meanwhile, the fastening bolt 2 presses the conductive gasket 3 between the fastening bolt 2 and the fastening buckle 4, so that the fastening bolt 2, the conductive gasket 3, the fastening buckle 4 and the external cable 1 are connected.

Illustratively, the second power supply pin 12 may have the same structure as the first power supply pin 11. Two leads 8 may be used, with one end of the lead 8 connected to the conductive pad 3 and the other end connected to the power input 6 of the power conversion module. Thus, the power input terminal 6 of the power conversion module can be connected to the first power pin 11 and to the second power pin 12 by means of the two leads 8.

In one embodiment, the temperature sensor 30 may include a sensing probe 5 and a control cable 32, the control cable 32 being connected to the sensing probe 5, as shown in FIG. 2.

The sensing probe 5 may be disposed at the center of the first power pin 11, the second power pin 12, and the protection pin PE. If the detection probe 5 is not disposed at the center of the three pins, the detection accuracy may be inconsistent, for example, if the detection probe 5 is closer to the first power supply pin 11, the temperature threshold corresponding to the first power supply pin 11 will be lower, and the temperature threshold corresponding to the pin farther away from the detection probe 5 will be higher, which results in inconsistent detection accuracy of the detection probe 5. Therefore, the detection probe 5 can be arranged at the center positions of the first power supply pin 11, the second power supply pin 12 and the protection pin PE, and the detection probe 5 can well detect the corresponding temperature signal no matter which pin is in poor connection, so that the detection accuracy consistency of the detection probe 5 is ensured.
