Referring to the cable assembly of the high Wen Bianping structure shown in fig. 1, which is suitable for the electrical connection of communication equipment inside an object to be transmitted in the aviation field, comprises a bus bar, a first connector 2 and a braided sheath, wherein the bus bar is arranged in a flat-shaped structure, the first connector 2 is installed on the total communication equipment inside the object to be transmitted, the first connector 2 is used as a connector of a mother communication equipment, control signals can be transmitted to a plurality of child communication equipment through the bus bar,

The braided sheath is sleeved with the bus harness (i.e., the cable bus harness), and preferably, the bus harness and the braided sheath are connected by an integral braiding technique. One end of the bus bundle is arranged on the first connector 2, the other end is electrically connected with other communication equipment in the object to be transmitted, the invention adopts the bus bundle with a flat structure to perform wired signal transmission, the utilization rate of the internal space of the object to be transmitted is improved, the function of signal transmission in a narrow space is realized, and the problem of stress concentration possibly occurring when the round cable is bent can be avoided. The cable with the flat structure has higher flexibility and bending performance, and can better adapt to bending and bending requirements of a narrow space due to the specificity of the cross section shape of the cable, for example, a mounting seam is reserved in an object to be transmitted, and a bus harness is mounted in the mounting seam, so that the performance of the cable is not affected.

The integral braiding technology is a common technological process in fiber product production, and through interlacing fiber to form one integral structure, the integral braiding technology may interweave several fiber or wire to form one firm structure, resulting in raised product strength and durability. The cable is braided on the outer layer to form a tight braided structure. The structure can effectively improve the performances of abrasion resistance, stretching resistance, bending resistance and the like of the cable. Thereby prolonging the service life of the cable. Compared with the traditional cable manufacturing process, the integrated braiding technology simplifies the cable manufacturing process and reduces the production cost. Secondly, the quality and performance of the cable can be improved, making it more reliable and durable.

Preferably, the braided sheath is braided from quartz glass filaments. The traditional mode adopts nylon yarn to wrap round wire harness, because nylon yarn's high temperature resistance is relatively poor, generally, needs to add other inoxidizing coating and be used for preventing the adverse effect that high temperature brought. The invention adopts the quartz glass fiber to form the braided sheath by the same machine (adopts an integral braiding technology), not only improves the high temperature resistance of the bus harness and keeps stable electrical performance in a high temperature environment, so that the cable can normally work for 30min in a 450 ℃ environment, but also has good electromagnetic shielding performance, can effectively reduce the influence of external electromagnetic interference on the signal wire, improves the stability and reliability of signal transmission, reduces signal loss and leakage, and ensures the signal transmission quality.

As the embodiment provided herein, the bus harness includes a first harness, a second harness, and a third harness, each of which is provided in a flat-shaped structure and is correspondingly sheathed with a first sheath 11, a second sheath 12, and a third sheath 13, wherein,

One ends of the first wire harness, the second wire harness and the third wire harness are respectively installed on the first connector 2, the other ends of the first wire harness, the second wire harness and the third wire harness are respectively provided with the second connectors 4, and each second connector 4 is respectively and correspondingly installed on sub-communication equipment in the object to be transmitted. It should be noted that: the first wire harness, the second wire harness and the third wire harness are preferably divided by signals of different functions transmitted, for example, the first wire harness is composed of multiple wire harnesses, and a plurality of sub-communication devices of the same type are connected in a butt joint mode.

As an embodiment provided in the present case, the first sheath 11, the second sheath 12 and the third sheath 13 are all left with a margin, so as to facilitate practical installation, for example, the accessory pressing plate of the connector tail is filled with a corresponding margin to ensure the pressing of the pressing plate. The dimensions of the bus bundles are all such that the width is less than 30mm and the thickness is less than 10mm.

Further, the first connector 2 and the second connector are HT-50 series high-temperature rectangular connectors, and the bus harness is FY4BQ-450-2 series wires, so that the performance requirement of high-temperature resistant use is met.

The foregoing is merely specific embodiments of the disclosure, but the protection scope of the disclosure is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the disclosure are intended to be covered by the protection scope of the disclosure. Therefore, the protection scope of the present disclosure shall be subject to the protection scope of the claims.
