Description

Technical Field

[0001] This utility model belongs to the technical field of installation clamps for cables or wires (IPC classification H02G3 / 32), and relates to the structural innovation and improvement technology of cable fixing auxiliary devices in aerospace technology. Background Technology

[0002] The space environment, also known as the cosmic environment, refers to the sum of all natural conditions and phenomena existing in outer space beyond Earth's atmosphere. Research on the space environment is crucial for understanding the origin and evolution of the universe, as well as the relationship between Earth and the universe. Cables serve multiple functions, including control installation, signal transmission, and power delivery, and are a common and indispensable component in the aerospace field. In the space environment, cable installation and fixing, while based on existing technologies, requires further innovation and development.

[0003] Choosing the right cable laying method is crucial for ensuring the transmission quality, reliability, and construction and maintenance of the line.

[0004] When laying cables such as electrical cables and optical cables, clamping mechanisms are often required to hold and fix the cables at the corresponding installation points. In the existing technology, cable clamping mechanisms generally consist of two parts: a clamping component and a fixing component. The clamping component is used to clamp the cable, and the fixing component is used to fix it to the corresponding installation point. The clamping component and the fixing component are generally integrated into a fixed structure, which is easily constrained by the on-site space environment, making installation difficult, inconvenient for cable laying, and with low installation flexibility.

[0005] Patent application 202222604009.6 discloses a cable holder, including a fixing component, a clamping component, and a connector. The clamping component is used to clamp cables, and the clamping component is rotatably connected to one side of the fixing component through the connector.

[0006] Existing clamps and their installation structures are inconvenient for binding and fixing, and have significant defects in safety and durability in the space environment. At the same time, since metal materials are required, metal components on spacecraft must be grounded, which makes them prone to damage to substrates, cables, battery cells and other products during operation. There is also a risk of conducting electricity with the circuit, requiring multiple layers of safety protection measures, which greatly increases the workload and product risk. Utility Model Content

[0007] This utility model proposes a fixing clip for cable laying and binding in a spatial environment, aiming to solve the technical problem that existing cable clamping components are easily constrained by on-site spatial environmental factors, making it inconvenient to lay and bind cables in a spatial environment.

[0008] Therefore, this utility model includes a base, a raised support, and a glue groove; the raised support is provided with a partial upward protrusion on the top surface of the base, and the glue groove is provided on the bottom surface of the base.

[0009] The base has a rectangular perforated groove in its center, and a raised support spans and is fixed above the perforated groove. The base has a rectangular plate structure. The raised support has a trapezoidal structure.

[0010] Furthermore, to achieve the above objectives, this utility model is configured as follows:

[0011] In particular, a glue groove is provided on the bottom surface of the substrate; the glue groove is a diamond-shaped hollow groove. Alternatively, a glue groove is provided on the bottom surface of the substrate; the glue groove is a diamond-shaped blind hole groove.

[0012] In particular, adhesive nails are installed on the bottom surface of the base; the adhesive nails have a cylindrical structure.

[0013] In particular, an auxiliary support is provided next to the raised support on the top surface of the base; the raised part of the auxiliary support is an isosceles triangle structure or a circular arc structure.

[0014] In particular, adhesive holes are provided at the edge of the substrate. The inner diameter of the lower section of the adhesive hole is larger than that of the upper section.

[0015] Compared with existing technologies, the advantages of this utility model are: It adopts an integrated design structure, eliminating the need for drilling and avoiding damage to cables or solar array panels. Cable bundles can be securely tied to the solar array panels using cable ties. During installation, the substrate can be rotated at an appropriate angle according to the cable bundle's extension direction before bonding, avoiding structural damage caused by drilling multiple mounting holes on the solar array panel surface due to adjusting the fixing position. It is suitable for binding and fixing cables of various diameters in various spatial environments, adapting to different binding angles, laying directions, and changes in fixing positions, exhibiting high adaptability. It can be flexibly adjusted according to the spatial environment, installation location, or installation requirements, reducing the difficulty of cable bundle laying and fixing, and making the installation method more flexible. It reduces the constraints of spatial environmental factors at the installation site and improves the convenience of cable laying. The cable fixing clip structure is simple and easy to bond and install, is firm and safe, has stable performance, is insulating and heat-resistant, and will not damage the substrate, solar cells, cables, or other products, avoiding the risk of electrical continuity and significantly improving safety.

[0026] The space environment mainly consists of several parts, including the interstellar space environment and the Earth's space environment. The interstellar space environment refers to the vast space between galaxies, filled with sparse interstellar matter such as gas, dust, and cosmic rays. The space environment has extreme physical conditions, making it an extremely challenging field of research. These include: high vacuum (extremely low, almost zero, matter density); strong radiation (including solar radiation and cosmic rays, posing a serious threat to spacecraft and astronauts); and microgravity (objects exhibit motion patterns drastically different from those on Earth's surface). Impacts on Earth's ecosystems also play a role.

[0027] 1) The impact of the space environment on human spaceflight activities includes: spacecraft launch, operation, and return: factors of the space environment need to be fully considered. For example, solar radiation and cosmic rays can damage the materials and electronic equipment of spacecraft, requiring special protective measures.

[0028] 2) Astronauts' physiological and psychological state: The microgravity environment will affect the physiological and psychological state of astronauts, requiring corresponding training and adaptation.

[0029] 3) Space debris and meteoroids: These celestial bodies pose a threat to the safety of spacecraft, requiring the establishment of a comprehensive monitoring and early warning system.

[0030] In spatial environments, cable clamps are essential tools for ensuring the neatness, safety, and efficient operation of cables. Also known as cable fixing clamps or cable clips, cable clamps are primarily used to secure cables and other types of wires, preventing them from moving, twisting, or sagging during transportation and use, thus maintaining the stability and reliability of the cable system. Cable clamps effectively fix cables in designated positions, preventing displacement or sagging caused by external forces or their own weight. Through proper layout and securing, cable clamps can keep cables neatly arranged, improving space utilization and making the cable system more aesthetically pleasing. Some cable clamps use special materials and designs, such as those with rubber pads or insulation layers, to protect cables from mechanical damage and chemical corrosion. Securely fixing cables prevents safety hazards such as electric shock and short circuits caused by loose or sagging cables. Classified by material, plastic clamps are lightweight and easy to install, suitable for securing thinner, more flexible wires or cables. They are relatively inexpensive and suitable for large-scale use. Metal clamps, such as aluminum alloy or stainless steel clamps, have higher strength and durability, suitable for securing thicker cables or use in harsh environments. Some metal cable clips also feature rubber pads to enhance insulation and protect cables. Composite material cable clips combine the advantages of various materials, such as lightweight yet high strength, corrosion resistance, and good insulation, making them suitable for cable securing in special applications.

[0031] Research shows that in the aerospace field, the output of solar array panels needs to be connected to the corresponding components of the satellite via cables. The cables leading out from the solar array panels need to have an exit end set about 20mm from the edge of the panel. At this position, auxiliary structures are needed to bind and fix the cables to prevent them from drifting around and interfering with the normal operation of other individual units.

[0032] The principle of this invention lies in the design of a cable bundle fixing clip structure using a colloidal bonding method, which facilitates the selection of stable, insulating, and high-temperature resistant organic synthetic materials, greatly improving safety compared to metal materials.

[0033] In this invention, the cable bundle is placed on top of the raised support and secured with cable ties. It is suitable for cable bundles of different sizes and diameters.

[0034] This utility model includes: a base 1, a raised support 3, and a glue groove 8.

[0035] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0036] The contents of this utility model can be more easily understood by referring to the following preferred embodiments and examples.

[0037] Example 1: As shown in the attached document Figure 1 As shown, a raised support 3 is provided on the top surface of the base 1, and a glue groove 8 is provided on the bottom surface of the base 1.

[0038] Preferably, a rectangular hollow groove 2 is formed in the middle of the base 1, and the raised support 3 spans and is fixed above the hollow groove 2.

[0039] Preferably, the base 1 has a rectangular plate structure.

[0040] Preferably, the raised support 3 has a trapezoidal structure.

[0041] In the embodiments of this utility model, as shown in the appendix Figure 2 As shown, an adhesive groove 8 is provided on the bottom surface of the substrate 1. The adhesive groove 8 adopts a diamond-shaped hollow design, or the adhesive groove 8 adopts a diamond-shaped blind hole structure design, in order to effectively increase the adhesive area and bonding strength on the bottom surface of the substrate 1, and at the same time, to increase the frictional resistance.

[0042] In this embodiment of the invention, the substrate 1 and the raised support 3 are made of polyimide, a material with excellent insulation properties. Its dielectric constant is 4.0, and its dielectric loss is only 0.004 to 0.007, classifying it as an F to H grade insulating material. Using this material eliminates the need for grounding, improves the overall reliability of the circuit, and its tensile strength, elastic modulus, creep resistance, and wear resistance are sufficient to withstand complex spatial environments.

[0043] The implementation principle of this embodiment is as follows: when needed, as shown in the appendix Figure 3 As shown, adhesive is applied to the bottom surface of the substrate 1 and adhered to the edge of the solar array panel 7 at a distance of 15mm. Some of the adhesive is squeezed into the hollow groove 2 or the glue groove 8, and some of the adhesive is pressed out from the side of the bottom edge of the substrate 1. That is, the cable laying and binding fixing clip is used to fix the cable bundle 6 to the edge of the solar array panel 7 in the space environment. The cable bundle 6 is wrapped and tied to the raised support 3 with the cable tie 5. In particular, the cable bundle 6 is tied to the raised platform of the trapezoidal structure of the raised support 3, which is stable and firm. The cable bundle 6 outlet position is accurately fixed to meet the requirements of the space environment.

[0044] In this embodiment, a reasonable layout is implemented before installation, with the position and number of fixing clips planned according to the cable routing and length to avoid excessive bending or stretching of the cables. After the base 1 is bonded and fixed and the cable bundle 6 is tied, the fixing clips need to be checked regularly for looseness or damage, and replaced or tightened in a timely manner. This effectively fixes and organizes the cables, improving space utilization and the stability and reliability of the cable system.

[0045] Example 2: As shown in the attached document Figure 4 As shown, adhesive nails 9 are provided on the bottom surface of substrate 1. The adhesive nails 9 have a cylindrical structure to further enhance the adhesive bonding strength on the bottom surface of substrate 1.

[0046] Example 3: As shown in the attached document Figure 5As shown, an auxiliary support 10 is provided next to the raised support 3 on the top surface of the base 1. The raised part of the auxiliary support 10 has an isosceles triangular structure or an arc structure. The auxiliary support 10 is used to fix the second binding point of the cable bundle 6 at the corner or bend structure, so as to prevent the cable bundle 6 from knotting due to its own tension.

[0047] In this embodiment of the invention, to further enhance the bonding strength between the substrate 1 and the solar array panel 7, adhesive holes 11 are provided at the edge of the substrate 1. In particular, the inner diameter of the lower section of the adhesive hole 11 is larger than the inner diameter of the upper section. During the bonding process of the substrate 1, some adhesive is squeezed into the adhesive hole 11, so that the substrate 1 and the solar array panel 7 are firmly connected as one unit.

[0048] It should be noted that the various specific technical features described in the above embodiments can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, this application will not describe the various possible combinations separately. Furthermore, various different embodiments of this application can also be arbitrarily combined, as long as they do not violate the spirit of this application, and they should also be regarded as the content disclosed by this invention.
