Description

Technical Field

[0001] The invention belongs to the field of satellite cables, and in particular relates to a satellite cable fixing bracket and a cable bundling method. Background Art

[0002] Satellite cables are complex. Some units are relatively high, and their electrical connectors face the top. The cables are fixed on the cabin board where the units are located from the electrical connectors on the units end. This part of the cables is suspended in the air. When the satellite is undergoing vibration tests or is in the launch state, the suspended cables will shake, affecting the reliability of the connection between the electrical connector on the unit end and the electrical connector on the cable end.

[0003] There are many pipelines in the propulsion subsystem on the satellite, and most of them are low in height. Cables cannot pass under the pipelines and can only pass over them from above. For satellites with narrow space, the space for cable routing is even narrower. When there are many cables and cables with different functions need to be routed separately, the cables need to be divided into several parts in a stepped shape.

[0004] The Chinese patent document CN117748377A discloses a satellite cable fixing bracket and its installation method. The bracket is made of aluminum alloy material and is fixed to the satellite by gluing. The appearance is an "I"-shaped structure. The four corners of its mounting surface are rounded, and there are two exhaust glue holes on both sides of the mounting surface; there are two waist-shaped holes and two cable tie slots in the middle of the bracket.

[0006] After searching, no design method has been found that can simultaneously meet the requirements of three-dimensional orientation and simultaneous fixation of multiple rows of cables, so as to solve the problems of fixation of lead-out cables of single-machine electrical connectors at high heights, bundling of cables across pipelines, and laying of cables in narrow spaces, thereby improving the reliability of satellite cable fixation.

[0040] DETAILED DESCRIPTION

[0041] The present invention is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the present invention, but are not intended to limit the present invention in any form. It should be noted that, for those of ordinary skill in the art, several changes and improvements can also be made without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0042] The invention provides a satellite cable fixing bracket, comprising a bracket panel, a mounting base, reinforcing ribs, a weight-reducing groove, a tie-belt binding groove and a mounting hole.

[0043] like Figure 1 As shown, the overall structure of the present invention is shown, the bracket panel is perpendicular to the mounting base, and two rows of tie-tie binding grooves symmetrically penetrating the bracket panel are provided on the bracket panel. The lower end of the satellite cable fixing bracket is designed with reinforcing ribs on both sides close to the mounting base, which are symmetrically distributed on both sides to support the panel bracket and improve the strength and rigidity of the overall bracket. Waist-shaped weight-reducing grooves are respectively provided at the reinforcing ribs on both sides to reduce the weight of the bracket.

[0044] The bracket panel is the base of the satellite cable fixing bracket. The cables running horizontally or vertically are bundled along the bracket panel, providing sufficient installation surface and support area for the cables, which can stabilize the cables. The satellite cable fixing bracket is made of magnesium alloy material. Compared with other metal materials, magnesium alloy has a lower density, which can not only meet the mechanical requirements of the bracket, but also reduce the weight of the bracket.

[0045] The bracket tie-wrap bundling grooves are a series of rectangular grooves for bundling cables. The tie passes through two adjacent bundling grooves to bundle the cables on the bracket panel. The tie passes through the upper and lower bundling grooves of the bracket to bundle the cables horizontally. The tie passes through the left and right bundling grooves of the bracket to bundle the cables longitudinally.

[0046] The bracket mounting base is provided with four mounting holes, which are symmetrically distributed in two rows, symmetrical about the bracket panel and symmetrical about the center plane of the bracket panel, to ensure the stability of the satellite cable bracket installation. The bracket is connected to the satellite cabin panel through the mounting holes, specifically, titanium alloy screws are used to fasten the corresponding threaded holes on the satellite cabin panel.

[0047] like Figure 2 As shown, the bundling method for horizontally routed cables of the present invention is shown. The bundling method for horizontally routed cables is: the two ends of the cable tie are respectively passed through the upper and lower adjacent bundling grooves to fix the cable on the bracket panel between the upper and lower adjacent bundling grooves.

[0048] Furthermore, for situations where the cables are routed horizontally, such as when there is a propulsion pipeline in the middle occupying the space for the cable routing, a cable fixing bracket can be placed at each end, and the cables can be fixed on the two brackets respectively. The cables are higher than the propulsion pipeline, that is, the cables are routed across the propulsion pipeline. Furthermore, for satellites with narrow spaces, the cable routing space is very cramped. In order to save cable routing space, the cables can be divided into several horizontally parallel rows and tied to the cable fixing brackets with cable ties. For cables with different functions, such as high-power cables, signal cables, pyrotechnic cables, etc., when they need to be bundled separately, they can also be divided into several parallel rows and tied to the bracket panel with cable ties to avoid electromagnetic interference between cables with different functions.

[0049] like Figure 3 , Figure 4 As shown, the bundling method of the longitudinally routed cables of the present invention is shown. The bundling method of the longitudinally routed cables is as follows: the two ends of the tie are respectively passed through the two adjacent left and right bundling grooves, and the cables are fixed on the bracket panel between the two adjacent left and right bundling grooves. Furthermore, for a single machine with a relatively high height and an electrical connector facing the top side, if the cable led out from the electrical connector at the single machine end is directly fixed on the satellite cabin board, a relatively long section of the cable will be suspended in the air, and the cable at the root of the electrical connector will be subjected to force. In view of this situation, the cable fixing bracket of the present invention can be used to fix the cable led out from the electrical connector at the single machine end longitudinally on the bracket panel through a tie, which can prevent the cable from being suspended in the air and reduce the force on the cable at the root of the electrical connector.

[0050] For cables that are routed vertically, you can also adjust the bundling method of the cable tie to fix the cables on the side of the bracket, flexibly adjust the angle of the cable route, and meet the requirements of different cable bending radius. For cables that are routed vertically, when the routing space is limited or cables with different functions are routed separately, they can be bundled in three columns, one column is bundled in the middle of the bracket panel, and the other two columns are bundled on both sides of the bracket.

[0051] In the description of the present application, it should be understood that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0052] The above describes the specific embodiments of the present invention. It should be understood that the present invention is not limited to the above specific embodiments, and those skilled in the art can make various changes or modifications within the scope of the claims, which does not affect the essence of the present invention. In the absence of conflict, the embodiments of the present application and the features in the embodiments can be combined with each other arbitrarily.
