Description

Technical Field

[0001] The utility model belongs to the field of electrical control cabinet equipment and relates to a cable clamp and an electrical control cabinet. Background Art

[0002] Electrical control cabinets in chemical fiber production are a crucial component of the control system, primarily used for electrical control and monitoring of chemical fiber production equipment. These cabinets typically contain various electrical components, such as circuit breakers, contactors, relays, inverters, and controllers. These components, through rational wiring and connection, enable functions such as starting, stopping, speed regulation, and protection for chemical fiber production equipment. However, due to the excessive number of electrical components and cables within the control cabinets, subsequent replacement of electrical components within the cabinets can lead to entanglement of multiple cables, and the removal of connected electrical components can hinder maintenance personnel's inspection and replacement.

[0003] At present, in order to facilitate subsequent maintenance, multiple cables are bundled during wiring. The existing technology usually uses cable ties or snap-on fixing clips for bundling. However, these bundling methods are not so convenient to use. Secondly, when bundling multiple cables, ordinary fixing clips are not flexible enough, which limits the stability of the fixation and may even make it unusable.

[0004] For example, patent application CN202323025444.4 discloses an electrical control cabinet containing a combing line rack. By arranging multiple wire management racks inside, and setting a wire pressing plate inside the wire management rack, the wires can be better organized, and the multiple wire management racks can be raised and lowered, and the unlocking and fixing operations are simple and convenient to use. In the control cabinet, the wires and equipment instruments are respectively in two spaces, which do not affect each other, are more beautiful, easy to maintain, and facilitate the progress of work. However, in the electrical control cabinet, the wires on the multiple wire management troughs are uniformly pressed by the wire pressing plate. When a single wire needs to be disassembled, the wire pressing plate needs to be removed first, and other wires that do not need to be disassembled may fall off in the process, making disassembly and assembly inconvenient. Moreover, since the shapes of the wire pressing plate and the wire management trough are fixed, it is not convenient to adjust according to different wire sizes, which is not conducive to clamping wires of various sizes.

[0005] Therefore, a cable clamp and an electrical control cabinet are needed to solve the above problems. Utility Model Content
