Description

Branch protection device of photoelectric composite cable Technical Field The utility model relates to the technical field of anti-drop of an access node of a photoelectric composite cable, in particular to a branch protection device of the photoelectric composite cable. Background The photoelectric composite cable is commonly used for transmitting power and signals and is widely applied to the fields of communication, power, traffic and the like. In these applications, the branch access of the optical-electrical composite cable is a critical element. In particular in harsh environments, access points for optical-electrical composite cables often face some potential safety hazards and technical challenges, with cable release issues being particularly pronounced. Cable looseness typically occurs at access points or branch points, where the connection is exposed to the environment and is susceptible to external forces, shock, temperature differential changes, mechanical stress, or improper installation. Especially in the long-time use process, the connection between the access cable and the photoelectric composite cable is easy to loosen or fall off due to temperature change, humidity fluctuation or external tension. The cable is loosened to cause signal or power transmission interruption, and serious safety accidents such as equipment failure, electrical short circuit, fire disaster and the like can be caused to cause serious property loss and casualties. Most of the existing cable connection protection schemes only provide a single fixing mode, and lack adaptability to external force and vibration. In some cases, the protection device can be fixed at an early stage, but the stability of the connection point gradually decreases with the passage of time or the change of environmental conditions, and the stable connection cannot be maintained for a long period of time. Therefore, there is a need for a protection device that provides reliable fixation over a long period of time and that effectively prevents cable loosening, especially at the junction of an optical-electrical composite cable and an access cable. Disclosure of utility model The utility model aims to provide a branch protection device of a photoelectric composite cable, which ensures the stability of cable connection through a multiple fastening design, prevents the cable from loosening due to external force or environmental change, further improves the use safety and reliability of the photoelectric composite cable, and is particularly suitable for electric power and communication facilities running for a long time in a complex environment. The branch protection device comprises a clamping ring, a spring buckling rod, elastic buckling pieces and gasket nuts, wherein the clamping ring is clamped at a branch access end of the photoelectric composite cable, two sides of the end part of the clamping ring are movably connected with the spring buckling rod through elastic pin shafts, the spring buckling rod is arranged in a rotating mode relative to the clamping ring, buckling pins are arranged at the tail ends of the spring buckling rods, the elastic buckling pieces are sleeved on the outer sides of the access cable, through holes are formed in the middle of the elastic buckling pieces, first buckling edges are arranged on the top side and the bottom side of the elastic buckling pieces, second buckling edges are arranged on two sides of the front end of the elastic buckling pieces, the gasket nuts are arranged on the inner sides of the elastic buckling pieces and are fixed through the first buckling edges, and the gasket nuts are locked on the outer sides of the access cable through internal threads. Preferably, the first fastening edge is a fixed fastening edge, and through the tight connection with the gasket nut, the first fastening edge plays a primary fixing role to prevent the gasket nut from displacement or loosening. Preferably, the second fastening edge is an elastic fastening edge with deformation. The inner side of the second buckling edge is propped against the outer side of the access cable, and a buckling groove matched with the buckling pin is formed in the outer side of the second buckling edge. The second fastening edge can be deformed by external force in the installation process, so that the gasket nut can be firmly fastened on the inner side of the gasket nut. When the gasket nut is locked to the outer side of the access cable through the internal thread, the second buckling edge further enhances the tightness of the connection due to the elastic deformation effect of the second buckling edge. Preferably, the buckling pin corresponds to the buckling groove at the outer side of the second buckling edge, and rotates along with the spring buckling rod to be buckled with the buckling groove so as to firmly connect the access cable with the photoelectric composite cable. The buckling pin is matched with the buckling groove at the outer
