Description

Clamp for fixing aviation shielding cable

Technical Field

The utility model relates to a clamp technical field specifically is a clamp that is used for aviation shielded cable to fix.

Background

Aviation shielded cable is the important conduction cable that aviation flight field was used for transmitting signals such as data, instruction, often is the instruction that is used for transmitting the external information that the aircraft acquireed and transmits control center and sends, for the maintenance of convenient aircraft to and reduce aircraft circuit potential safety hazard, pipeline (including aviation shielded cable) in the aircraft often need rationally carry out winding displacement design and fix, in order to avoid the pipeline to twine each other, also makes things convenient for the maintenance and the maintenance in later stage simultaneously.

The arrangement and the fixation of pipelines can not be separated from a clamp, the signal shielding cables of the prior aircraft usually extend from all structural points of the aircraft, and are finally converged to form a cable which is communicated to an operation center of the aircraft after being converged, at present, when the wire harness similar to the converged wire harness is fixed, the adopted clamps are mainly divided into two types, one type is an annular clamp, all the wire harnesses are directly wrapped in the annular clamp and are fixed on related fixing hole positions through fastening bolts or screws, in the fixing mode, skins of all the shielding cables forming the wire harness are in contact extrusion with each other, so that point and line stress is formed, and the cable is easy to deform by the position of a hoop; the other type is a linear type buckle, although each shielding cable forming the wiring harness can be locked by an independent hoop when the buckle clamp is used, the transverse depth of the buckle is long, so that each cable is fixed side by side after the wiring harness is fixed, the whole wiring harness occupies a large mounting area after the inner wall of an aircraft is fixed, and the mounting of each buckle is usually fixed by at least two bolts, so that the workload of the aviation shielding cable wiring harness during fixing is greatly increased.

We have therefore proposed an improved clip which combines a clip and a collar.

SUMMERY OF THE UTILITY MODEL
