Problems solved by technology

Moreover, since the wire thread insert is screwed into the matrix along the thread, when the matched screw is rotated out, the wire thread insert may also be brought out. This situation often occurs in actual use.
In addition, the wire screw sleeve itself has a certain residual magnetism, so that the embedded connector with the wire screw sleeve cannot be used for some satellites that have strict requirements on magnetic properties.
The manufacturing process of embedded connectors of aluminum alloy inlaid steel wire bushes is also relatively complicated, which cannot meet the high-efficiency production requirements proposed by aerospace vehicle engineering

Embodiment Construction

[0010] The present invention will be described in more detail below in conjunction with the accompanying drawings and specific embodiments.

[0011] as attached figure 1 As shown, an embedded connector for an aircraft uses Al-Zn-Mg-Cu aluminum alloy as the base 2, and the weight percentage of the aluminum alloy is: Zn: 5.4-5.8%, Mg: 2.7-3.5%, Cu: 1.6- 2.2%, Cr: 0.2-0.35%, Mn: 0.15-0.35%, Ti: 0.05-0.15%, Ni: 0.01-0.1%, Fe: 0-0.35%, Si: 0-0.15%, and the rest is Al.

[0012] A bottom hole 3 is arranged axially on the aluminum alloy substrate 2, and an internal thread 1 is tapped on the upper part of the bottom hole 3, and the internal thread 1 is treated by phosphoric acid anodization.

[0013] In addition to the above-mentioned Al-Zn-Mg-Cu aluminum alloy materials, the aluminum alloy materials used in the present invention can meet the following requirements, and the high-strength aluminum alloys mentioned in the present invention refer to aluminum alloys that meet the requirem...

Abstract

An aircraft embedded connector, in particular to an aluminum alloy-based embedded connector used for aircraft honeycomb sandwich structure panels. The embedded connector is made of high-strength aluminum alloy, with threaded holes on the aluminum alloy substrate, and the threads are anodized with phosphoric acid. The connecting piece omits the wire screw sleeve structure in the existing connecting piece, and is especially suitable for being used as an embedded connecting piece of an aircraft with strict requirements on magnetic properties.

Description

technical field [0001] The invention relates to an embedded connector for aircraft honeycomb sandwich structure panels, in particular to an aluminum alloy-based embedded connector. Background technique [0002] The honeycomb sandwich panel is a light-weight structural component widely used in aerospace vehicles. The connection between the honeycomb sandwich panel and the structural parts, and the installation of instruments and equipment on the honeycomb sandwich panel are realized through the connectors embedded in the honeycomb sandwich panel. of. Therefore, embedded connectors are an important part commonly used in spacecraft structures. As the types and functions of my country's aerospace vehicles are becoming more and more diverse and the number is increasing, the requirements for the structure of the aircraft are also getting higher and higher, so the requirements for embedded connectors are also becoming more and more diverse. Not only are the embedded connectors re...
