Description

Technical Field

[0001] The utility model relates to the technical field of power supply plugs, in particular to a port power supply plug with optical fiber. Background Art

[0002] There are some differences between the power plugs on the dock and common plugs. Since they are often used for high-power equipment or ships, the rated voltage and rated current are usually relatively large, such as 440V / 63A. At the same time, the dock power plug is usually made of wear-resistant and pressure-resistant materials, which can adapt to the harsh dock environment and high-power current transmission. Waterproof and dustproof performance must also be considered to ensure long-term stable and reliable power supply in a humid environment. With the update and upgrade of current production equipment automation, data information communication has been more and more widely used in equipment control. Existing dock power plugs or high-power power plugs will be equipped with optical fibers. Since optical fibers are weak currents, the strong current of the cable core will interfere with the communication of optical fibers and affect signal transmission; in addition, the docking between optical fibers is different from the docking between cable plugs, and they need to be plugged in and out separately.

[0003] For example, Chinese patent CN211743469U discloses a flameproof optical fiber composite high and low voltage cable connector for mining, including a plug assembly and a socket assembly for plugging and matching, wherein insulating material and a first conductive assembly are arranged in the plug assembly, and insulating material and a corresponding second conductive assembly are arranged in the socket assembly to realize hard-to-hard docking of the cable cores, and the connection is reliable and convenient; a connected optical fiber lead-out hole and a flameproof device are arranged on the side of the plug assembly, and an optical fiber channel is arranged correspondingly on the socket assembly, so that the optical fiber at the equipment end and the optical fiber at the rubber-sheathed cable end are connected in the flameproof device, effectively separating the connection between traditional cables and optical fibers, and avoiding the situation of strong electrical interference weakness; however, the above patent does not have moisture-proof and dust-proof properties, and is not suitable for occasions such as docks.

[0004] Therefore, it is necessary for technical personnel in this field to provide a port power supply plug with optical fiber, integrate the cable and optical fiber into one, ensure operational stability while improving waterproof and moisture-proof performance. Utility Model Content

Therefore, during installation, the operator only needs to use common fasteners such as bolts or screws to install the fiber optic box 20, thereby ensuring the convenience of installation and achieving quick installation.

[0024] In this embodiment, the connecting portion 11 is protruded on the outer surface of the plug body 10, and a plurality of mounting holes 12 are evenly distributed on the connecting portion 11 around the axis of the plug body 10. Two connecting pieces 22 are provided and symmetrically arranged. The connecting portion 11 is cooperatively connected between the two connecting pieces 22. A connecting hole 23 is opened on the connecting piece 22, and the connecting hole 23 corresponds to the mounting hole 12. The fastener passes through the connecting hole 23 and is cooperatively connected in the mounting hole 12.
