[0001] This utility model relates to the field of satellite technology, specifically to a satellite cable bracket that is easy to expand. Background Technology

[0002] During satellite assembly, cable network laying is required. Cable brackets are used to fix the cables, which solves the problem of excessive spatial variation of the cable when the cable is directly fixed to the surface of the structural plate, causing dragging force at the cable root and avoiding affecting the performance of the cable connection.

[0003] However, different types of satellites have different altitudes, and existing cable supports cannot meet the various needs when there are large differences in altitude.

[0004] Therefore, a satellite cable bracket that can accommodate cable fixing with large differences in height is needed. Summary of the Invention

It provides an easily expandable cable bracket for satellites, comprising a threaded cable bracket base, an expandable intermediate rod assembly, a detachable nylon base mounting seat connected to the expandable intermediate rod assembly, a bracket top threaded to the top of the expandable intermediate rod assembly, a nylon base connected to the expandable intermediate rod assembly via the nylon base mounting seat, nylon cable ties for bundling cables connected to the nylon base, and fastening screws connecting the nylon base mounting seat and the nylon base. The expandable intermediate rod assembly includes one or more intermediate rods, each comprising a hollow circular rod, a second external threaded protrusion connected to the bottom of the circular rod, a circular through hole horizontally connected to the circular rod, and a second internal threaded groove connected to the top of the circular rod. This invention, through the expandable intermediate rod assembly, makes the cable bracket easily adjustable to adapt to cable fixing needs at different heights.

[0006] This invention provides a satellite cable bracket that is easy to expand, including a threaded cable bracket seat, an expandable intermediate rod assembly, a nylon base mounting seat detachably connected to the expandable intermediate rod assembly, a bracket top threadedly connected to the top of the expandable intermediate rod assembly, a nylon base connected to the expandable intermediate rod assembly via the nylon base mounting seat, nylon cable ties connected to the nylon base for bundling cables, and fastening screws connecting the nylon base mounting seat and the nylon base. The cable bracket seat has a first internal thread groove in the center and a first external thread protrusion at the bottom of the top of the bracket. The expandable intermediate rod assembly includes one or more intermediate rods, each intermediate rod including a hollow circular rod, a second external threaded protrusion connected to the bottom of the circular rod, a circular through hole horizontally connected to the circular rod, and a second internal threaded groove connected to the top of the circular rod; The first internal thread groove is connected to the second external thread protrusion; The second internal thread groove corresponds to the threads of the first external thread protrusion and the second external thread protrusion.

[0007] In a preferred embodiment of the satellite cable bracket for easy expansion described in this invention, the circular rod further includes a weight-reducing groove extending vertically, and a circular through hole connected to the weight-reducing groove, wherein the diameter of the circular through hole is larger than the width of the weight-reducing groove. The nylon base mounting bracket includes a T-shaped post and a fastening nut that is threaded to the T-shaped post. The T-shaped post has a hollow structure, and the outer diameter of the T-shaped post is smaller than the diameter of the circular through hole.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example 1

[0016] like Figures 1-9 As shown, a satellite-use expandable cable bracket includes a threaded cable bracket seat 1, an expandable intermediate rod assembly 2, a nylon base mounting seat 3 detachably connected to the expandable intermediate rod assembly 2, a bracket top end 4 threaded to the top of the expandable intermediate rod assembly 2, a nylon base 5 connected to the expandable intermediate rod assembly 2 via the nylon base mounting seat 3, nylon cable ties 6 connected to the nylon base 5 for bundling cables, and fastening screws 7 connecting the nylon base mounting seat 3 and the nylon base 5. The cable bracket seat 1 has a first internal thread groove in the center and a first external thread protrusion at the bottom of the bracket top 4; The expandable intermediate rod assembly 2 includes one or more intermediate rods, each intermediate rod including a hollow circular rod 21, a second external threaded protrusion 22 connected to the bottom of the circular rod 21, a circular through hole 23 horizontally connected to the circular rod 21, a second internal threaded groove 24 connected to the top of the circular rod 21, and a weight reduction groove 25 extending in the vertical direction. The first internal thread groove is connected to the second external thread protrusion 22; The second internal thread groove 24 corresponds to the threads of the first external thread protrusion and the second external thread protrusion 22; A circular through hole 23 is connected to the weight reduction groove 25, and the diameter of the circular through hole 23 is larger than the width of the weight reduction groove 25; The weight-reducing groove 25 is connected to a plane milled from the circular rod 21; At least two sets of circular through holes are connected to the weight reduction groove 25, each set including four circular through holes facing four directions; The nylon base mounting seat 3 includes a T-shaped post 31 and a fastening nut 32 threadedly connected to the T-shaped post 31. The T-shaped post 31 has a hollow structure, and the outer diameter of the cylindrical surface of the T-shaped post 31 is smaller than the diameter of the circular through hole 23. The nylon base 5 is a saddle-shaped plate structure that slopes outward on both sides, with a fixed through hole 51 in the middle and slotted holes 52 at both ends for the nylon cable ties 6 to pass through. The fastening screw 7 passes through the fixing through hole 51 and the T-shaped post 31 in sequence and is connected to the fastening nut 32.

[0017] A mounting groove for the end face of the fastening screw 7 is provided on the fixing through hole 51; The upper surface of the bracket top 4 is a plate-like structure with slotted holes 52 in all four directions. The bracket top 4 can also be connected with nylon cable ties 6.

[0018] like Figure 1 The diagram shows the overall structure of the cable support. It mainly consists of a cable support base 1, an expandable intermediate rod assembly 2, a nylon base mounting base 3, a support top 4, a nylon base 5, nylon cable ties 6, and fastening screws 7. The nylon base mounting base 3 can be installed at different heights and orientations on the expandable intermediate rod assembly 2 according to the actual cable usage. The nylon cable ties 6 are used to bind the cable to the nylon base 5. Simultaneously, a slotted hole is pre-drilled at the top of the support top 4, allowing the nylon cable ties 6 to be directly fixed to the top slotted hole of the support top 4.

[0019] like Figure 2As shown in the diagram, the cable bracket is disassembled and explained. The expandable intermediate rod assembly 2 is mounted on the first internal thread groove of the cable bracket seat 1 through the second external thread protrusion 22 at the bottom. The other end of the expandable intermediate rod assembly 2 is a second internal thread groove 24, which can be connected to the second external thread protrusion 22 of the next expandable intermediate rod assembly 2 to increase the height of the entire cable bracket. The nylon base 5 is fixed in the circular through hole 23 of the expandable intermediate rod assembly 2 by fastening screws 7 and nylon base mounting seat 3. The top end 4 of the bracket is connected and fixed to the second internal thread groove 24 of the expandable intermediate rod assembly 2 through the external thread at the bottom.

[0020] like Figure 3 , 4 The detailed structure of the expandable intermediate rod assembly 2 is shown below. It mainly includes the following features: The overall shape is a circular rod 21; the second external thread protrusion 22 at the bottom of the rod is an M5 external thread; multiple mounting interfaces—circular through holes 23—for the nylon base 5 need to be provided in the middle of the circular rod 21; therefore, four planes are milled into the circular rod 21, each with a 4mm wide groove for weight reduction (weight reduction groove 25); three φ5 circular through holes 23 are evenly distributed along the weight reduction groove 25; each expandable intermediate rod assembly 2 has a total of 12 circular through holes 23, which are used to mate with the nylon base mounting seat 3; the second internal thread groove 24 at the other end of the expandable intermediate rod assembly 2 is an M5 internal thread; the M5 second external thread protrusion 22 of the expandable intermediate rod assembly 2 can mate with the M5 second internal thread groove 24 of another expandable intermediate rod assembly 2; the number of intermediate rods in the expandable intermediate rod assembly 2 is selected according to the height requirements; this example uses two intermediate rods.

[0021] like Figure 5 The diagram shows the configuration of the nylon base 5. The nylon base 5 is saddle-shaped with a through hole 51 in the middle for mounting to the satellite structural panel, which is secured with fastening screws 7. The nylon base 5 has symmetrical slotted holes 52 on both sides, through which nylon cable ties 6 can be passed to directly fix cables to the nylon base 5.

[0022] like Figure 6 , 7 Figure 8 shows a schematic diagram of the nylon base mounting seat 3. It consists of a T-shaped post 31 and a fastening nut 32. The cylindrical surface of the T-shaped post 31 is a φ5 circular structure, which can be fitted into the φ5 circular through hole 23 of the expandable intermediate rod assembly 2. Since the φ5 circular through hole 23 of the expandable intermediate rod assembly 2 is slightly larger than the 4mm wide groove, the T-shaped post 31, after being fitted into the φ5 circular through hole 23 of the expandable intermediate rod assembly 2, serves as a vertical limit. The end face of the T-shaped post 31 is slightly larger than the cylindrical surface. The fastening nut 32 and the fastening screw 7, together with the end face of the T-shaped post 31, restrict the axial displacement of the T-shaped post 31. The nylon base 5 is fixed in the circular through hole 23 of the expandable intermediate rod assembly 2 by the fastening screw 7 and the nylon base mounting seat 3.

[0023] When the individual units installed on the satellite are at a relatively high altitude, cable brackets are required for transition, to gather and secure the suspended cables at an appropriate height and direction. This increases the reliability of the cable connections.

[0024] The cable bracket and cable bundling status are as follows Figure 9 As shown, in this embodiment, the total height of the cable bracket is 160mm. The cable bracket base 1, the expandable intermediate rod assembly 2, and the bracket top 4 are all made of aluminum alloy 2A12-T4. The diameter of the circular rod 21 is 10mm. Figure 1 The distance between the two nylon base mounting seats 3 shown is 45mm.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
