[0020] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0021] See also Figures 1 to 3As shown, according to the embodiment of the first aspect of the present application, a 1553B bus cable for aerospace is provided to solve the problem that in the application process of modern 1553B bus cables, due to the complex wiring, a large number of bus cables are used, and in general, bus cables are mostly suspended wiring or cable brackets, which are easily stressed and fall off during the force application process of aerospace vehicles, resulting in the problem of virtual connection of bus cable wiring.

[0022] In response to the above problems, the present application discloses a 1553B bus cable for aerospace use. The main structure of the bus cable includes a cable sheath 1 and a cable core 2. The cable sheath 1 is wrapped around the cable core 2. A pair of data connectors 3 are respectively connected to the two ends of the cable core 2. External wiring is completed through the pair of data connectors 3. The data connectors 3 adopt an aviation plug structure. Furthermore, a sliding seat 4 is provided on the cable sheath 1, and the sliding seat 4 is used as an installation and fixing device for the bus cable.

[0023] Furthermore, the sliding seat 4 is a plate of an annular structure, and a plurality of slide grooves 5 are arranged along the inner ring of the sliding seat 4, and a plurality of slide rollers 6 are mounted on the plurality of slide grooves 5, and the circumference of the plurality of slide rollers 6 is tangent to the cable sheath 1. Under the action of the slide rollers 6, the contact between the sliding seat 4 and the cable sheath 1 is rolling contact. After the two ends of the data connector 3 of the bus cable are connected during installation, the fixing device 14 used in conjunction is installed and fixed, and the sliding seat 4 slides along the bus cable, and the sliding seat 4 on the bus cable is connected to the fixing device 14 to realize cable positioning. By adding a fixing point at the terminal of the bus cable, the fixing effect of the bus cable is improved;

[0024] In order to effectively fix the sliding seat 4 at one point of the bus cable, a sliding notch 7 is provided on the sliding seat 4, so that the sliding seat 4 can slide along the cable sheath 1 of the bus cable when it is not positioned, and a pair of tension seats 8 are symmetrically provided on both sides of the sliding notch 7, and a pair of tension seats 8 are provided on the pair of tension seats 8. The number of tension bars 9 is at least one pair and they are symmetrically arranged at both ends of the tension seats 8. After the cable positioning of the sliding seat 4 is completed, the pair of tension seats 8 are relatively moved by rotating the tension bars 9, so that the sliding notch 7 on the sliding seat 4 is closed, so that the sliding seat 4 wraps and fixes the cable sheath, so that the position of the sliding seat 4 is fixed;

[0025] Furthermore, in order to connect the sliding seat 4 with the fixed seat, a rotating groove 10 is opened on the sliding seat 4, and a rotating seat 11 is installed in the rotating groove 10. A support rod 12 is movably installed on the rotating seat 11, and a reverse pull fixing screw 13 is provided at the end of the support rod 12. The rotating seat 11 is assembled through the rotating groove 10 on the sliding seat 4. The rotating seat 11 can adjust the horizontal direction, and the support rod 12 can rotate relative to the rotating seat 11. The angle of the support rod 12 is adjusted to make the support rod 12 face the position of the fixer 14, and then the support rod 12 is connected to the fixer 14, thereby realizing the positioning and installation of the support rod 12.

[0026] Specifically, the plurality of slide grooves 5 are grooves of a plurality of rectangular structures and the bearing ring array is arranged in the slide seat 4 , and the slide roller 6 is partially exposed from the slide groove 5 , so that the slide roller 6 is in full contact with the cable sheath 1 .

[0027] Specifically, the opening angle of the sliding notch 7 is not less than 5° and not more than 10° to avoid the opening being too large.

[0028] Specifically, it also includes a fixture 14, which is a rectangular base, and has at least two mounting positions 15 arranged in parallel on the fixture 14, and a positioning sleeve 16 is movably mounted on the mounting position 15, and a threaded groove is provided on the positioning sleeve 16 to connect with the reverse pull fixing screw 13;

[0029] In the specific implementation process, a pair of screws are set on both sides of the fixer 14 to be fixed on the mounting frame of the aerospace vehicle. The positioning sleeve 16 is positioned through the mounting position 15 on the fixer 14. After the wiring of the bus cable is completed, the positioning sleeve 16 is rotated to make the positioning sleeve 16 threadedly connected with the reverse pull fixing screw 13, thereby pulling the middle section of the bus cable to achieve tightening of the bus cable and form a pulling effect on the bus cable. Furthermore, a polygonal mounting block 17 is set outside the positioning sleeve to facilitate the rotation of the positioning sleeve 16.

[0030] From the above, it can be generally known that the 1553B bus cable for aerospace use adopts a sliding seat 4 mounted on the cable sheath 1 of the bus cable. The sliding seat 4 can adjust the support rod 12 thereon in all directions, so that the support rod 12 is threadedly connected with the positioning sleeve 16 on the configured fixture 14, thereby achieving a pulling effect on the middle section of the bus cable through the sliding seat 4, thereby avoiding problems such as connection falling off when the bus cable is installed in the air.
