Description
Technical Field
The utility model relates to a protector specifically is a steel pipe mouth protects device of optical cable belongs to optical cable construction technical field.
Background
The directly buried cable passes through a large road, a highway, a railway, a culvert, a ditch and the like and needs to be protected by sleeving a steel pipe, generally, the steel pipe is buried before the cable is buried, then the cable passes through the steel pipe, and in the process of passing the cable through the steel pipe, because the end port of the steel pipe is relatively sharp, the cable is not processed or manually cared, the outer sheath of the cable is easily damaged, and even the cable core of the cable is damaged. Therefore, when the cable is inserted, protection measures are added at the inlet (the end of the cable inserted into the steel pipe mouth) and the outlet (the end of the cable inserted into the steel pipe mouth) of the steel pipe.
For the traditional protection measures, the following defects often exist:
1. and (3) full-artificial protection: the method has the advantages that the flexibility is high, the method has the defects that the influence of the responsibility of an operator is great, the cable is easily cut and rubbed at a pipe orifice without paying attention to the cable, the labor is wasted, the labor and the time are wasted, the efficiency is low, and the method cannot be endured after long-time work and manual fatigue;
