Description

Technical Field

[0001] The invention belongs to the technical field of wire harness fixing, and in particular relates to a clamp assembly and method used in a high-density wiring space. Background Art

[0002] Some aviation electrical equipment has a high degree of internal space integration and contains many wiring harnesses and cables, which makes wiring harness layout and fixation difficult and poor maintainability.

[0003] The traditional wiring harness fixing method usually uses clamps, screws, nuts, flat washers, spring washers, and rubber washers. Disassembly and assembly are time-consuming, and space for maintenance tools needs to be reserved during design. It is also easy to cause unnecessary small parts such as nuts, flat washers, spring washers, etc., which affects the safety of equipment use and thus the flight safety of the aircraft.

[0004] The patent document with application number CN2009201445825 discloses a wire and cable pipeline fixing clamp, which is composed of a metal band and a rubber pad. The rubber pad is mounted on the metal band, and the ears at both ends of the metal band are placed outside the rubber pad. The ears at both ends of the metal band have a screw hole, and the screws are placed in the screw holes, and are connected as a whole with self-locking nuts. The nut of the application is set on the outside of the ear, and the two ears cannot clamp the nut. At the same time, no bracket structure for adapting to the installation environment and connecting the installation platform is disclosed.

[0005] The patent document with application number CN2014206962547 discloses an aircraft cable clamp, which is composed of a clamp belt, a rubber pad, a self-locking nut, a screw and a wire harness clamp. The clamp belt is clamped on the main load-bearing structure of the aircraft through a rubber pad, and it is tightened with a self-locking nut A and a screw A. The rubber pad acts as a buffer and prevents the clamp belt from abrading against the main load-bearing structure. Finally, the wire harness clamp used to fix the cable is installed on the clamp belt through a self-locking nut B and a screw B. The clamp structure can be clamped and adjusted according to the thickness and shape of the main load-bearing structure. Although a rubber pad is provided in the application, the rubber pad is not on the clamp, and its fixed structure has less friction with the load-bearing platform through the rubber pad. The patent provides a long strip clamp belt and a self-locking nut, which is not suitable for use in high-density wiring space. Summary of the invention
