Description

Cross aircraft rib wire harness installing support

Technical Field

The utility model relates to an aviation electrical technology field especially relates to a span aircraft rib pencil installing support.

Background

Along with the continuous increase of large aircraft appearance, the continuous increase of structure frame distance, thickness, the type, quantity and the weight of cable constantly increase on the machine, and the continuous improvement of safe redundancy finally leads to the degree of difficulty constantly increasing that the cargo hold pencil laid. In particular by wiring harness routing of the reinforcing frame.

The design increases the enhancement frame wire harness support, not only plays the pencil fixed, has also guaranteed the biggest interval requirement of pencil and structure, pipeline simultaneously, plays simultaneously and prevents that the pencil from overweight flagging wearing and tearing, scalding the electric wire, avoids causing the flight accident.

SUMMERY OF THE UTILITY MODEL

Utility model purpose: the utility model provides a span aircraft rib frame pencil installing support solves at the fixed and protection problem of pencil in cargo hold frame and the frame interval is too big (more than 600 mm) frame and stringer region.

The technical scheme is as follows:

a harness mounting bracket for spanning an aircraft reinforcing frame, comprising: a bracket component 1 and a hoop 2; the rack assembly 1 comprises 2 sets of brackets 11 and a rack panel 12;

each set of carriages 11 comprises two carriages; 2 groups of brackets 11 are respectively arranged on the stringers at two sides of the reinforcing frame, one bracket in the group is arranged on the upper stringer, and the other bracket is arranged on the lower stringer; the 4 brackets 11 support the bracket panel 12;

three rows of mounting holes are arranged on the support plate surface 12; the mounting holes are used for fixing the clamps 2, each row of clamps form a wire harness channel, and similar wire harnesses are fixed in the same wire harness channel.

Further, a space exists between two adjacent wire harness passages.

Furthermore, the interval between the wire harness channels of different types of wire harnesses is larger than that between the wire harness channels of the same type of wire harnesses.

Furthermore, the distance between the adjacent mounting holes in the same row is in the range of [300, 400] mm.

Further, the lower mounting surface of the bracket 11 is fully conformed to the curved surface of the stringer.

Further, a lightening hole is arranged on the bracket panel 12.

Further, the upper mounting surface of the bracket is fully flush with the curved surface of the carrier panel 12.

Has the advantages that: the utility model discloses to span the pencil of aircraft rib, the form of raising with the support is fixed the pencil and is protected on the support, prevents wearing and tearing such as pencil and structure, pipeline equipment, has improved the reliable security of each system of aircraft cargo hold.

Detailed Description

The utility model provides a span aircraft rib wire harness installing support, as shown in fig. 1-2, include: a bracket component 1 and a hoop 2; as shown in fig. 3, the rack assembly 1 includes 2 sets of brackets 11 and a rack panel 12;

each set of carriages 11 comprises two carriages; 2 groups of brackets 11 are respectively arranged on the stringers at two sides of the reinforcing frame 4, one bracket in the group is arranged on the upper stringer 5, and the other bracket is arranged on the lower stringer 6; the 4 brackets 11 support the bracket panel 12;

three rows of mounting holes 13 are formed in the support plate surface 12; the mounting holes are used for fixing the clamps 2, each row of clamps form a wire harness channel, and similar wire harnesses are fixed in the same wire harness channel.

The utility model discloses earlier with four brackets with rivet connection for the mounting panel, be connected support and for the mounting panel riveting form and structure stringer again, fix screw, clamp for the pencil and lay on the mounting panel after having accomplished. The wiring harness is lifted through the support, the distance between the wiring harness and the structure and between the wiring harness and the pipeline is ensured, and meanwhile reliable fixation of the wiring harness and isolation and abrasion prevention protection of the wiring harness and the structure are achieved.
