Description

Technical Field

[0001] The invention belongs to the technical field of aircraft-specific cable routing, and in particular relates to a high support with screws. Background Art

[0002] Chinese patent publication number CN202280953U discloses a novel high support structure, primarily consisting of a high support body, bilaterally symmetrical fixed lugs at the bottom, an observation hole, and an embedded self-locking nut. The high support body is a hollow cylindrical structure with a transparent observation hole through its outer wall for observing the installed status of the padded clamping bolt. The self-locking nut has a ridged outer wall to prevent axial movement. The ridge is knurled to create strong friction with the inner wall of the base, preventing relative rotation during installation. However, when using this high support structure in limited space, such as in an aircraft cabin, it is necessary to first clamp the cable to the clamp. Then, with one hand, hold the screw and the other hand, insert the clamp and washer onto the screw. Finally, with one hand, support the clamp and washer while the other hand screws the screw into the self-locking nut inside the high support body. This installation process requires two hands, which is inconvenient and inefficient due to the limited space in an aircraft cabin. Summary of the Invention

[0003] In view of the above-mentioned defects of the existing high supports during installation, the object of the present invention is to provide a high support that is easy to install and an installation method thereof.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is:

[0005] A high support with screws includes a support base and a support nail. The support base has an installation cavity. The support nail includes a first installation section and a second installation section. The first installation section is connected to the installation cavity of the support base, and the first connecting section is axially limited by an elastic pin inserted through the first connecting section and the support base body. The second installation section is located outside the support base and is used to allow the assembly hole on the clamp for fixing the wiring harness to pass through and then be limited by a locking nut.

[0006] As an improvement to the above technical solution, a limiting boss is further provided between the first mounting section and the second mounting section, and the limiting boss is used for limiting the position between the support pin and the support seat, and between the support pin and the clamp.

[0007] As a further improvement of the above technical solution, the limiting boss and the first mounting segment and the second mounting segment are an integrally formed structure, and the limiting boss includes a first limiting surface connected to the first mounting segment and a second limiting surface connected to the second mounting segment, the first limiting surface is used for the installation limitation of the support nail on the support seat, and the second limiting surface is used for the support limitation of the clamp on the support nail.

[0008] As an improvement of the above technical solution, the support nail is a supporting round nail, the first mounting section is provided with an external thread, and the interior of the support seat is forcibly equipped with a support nut for cooperating with the thread of the first mounting section.

[0009] As a further improvement of the above technical solution, the outer wall surface of the support nut is provided with a protrusion, and the protrusion is used to limit the movement of the support nut in the installation cavity.

[0010] As a further improvement of the above technical solution, the outer wall surface of the support nut is further provided with axial knurling, and the axial knurling is used to limit the rotation of the support nut in the installation cavity.

[0011] As an improvement to the above technical solution, the cross section of the first mounting section is non-circular, and the first mounting section is embedded in the mounting cavity of the support seat.

[0012] As a further improvement of the above technical solution, the cross-section of the first installation section is square, D-shaped or triangular.

[0013] As an improvement to the above technical solution, the bottom of the support seat has a mounting hole for fixing the support seat on a support frame inside the aircraft.

[0014] As an improvement to the above technical solution, reinforcing ribs are further provided at the bottom of the support seat.

[0015] The aforementioned elastic terminal component and the connector using the same can achieve the following beneficial effects:

[0016] (1) The support nail is combined with the support base. The support nail adopts an installation structure that combines the first installation section and the second installation section. The structures at both ends of the support nail can be installed separately. The installation process does not affect each other, which improves the installation efficiency and expands the application range of high support.

[0017] (2) The high support body adopts a hollow structure inside, which reduces the weight of the product while ensuring the strength and rigidity of the product;

[0018] (3) The previous installation steps of the high support have been changed. During installation, you only need to use one hand to install the first installation section of the support nail into the support seat, then put the clamp on the second installation section, and use the locking nut with the other hand to lock the clamp on the second installation section. The installation can be completed with one hand, which solves the problem of difficult cable installation in a small space, further improves installation efficiency, and expands the application range of the high support.

In the description of the present invention, it should also be noted that, unless otherwise clearly specified and limited, the terms "setting", "installation" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0029] Reference Figure 1 、 Figure 2 In view of the technical problems that the existing high supports for cable support in local limited spaces of aircraft, which require two-handed operation for installation, are inconvenient to operate and have low installation efficiency, the present invention provides a high support with screws that can be easily installed in a small space. The present invention specifically includes a support seat 1 and a support nail 2. The support seat 1 mainly plays the role of fixed installation. The support seat 1 has an installation cavity 11, which is a hollow structure. While ensuring the strength and rigidity of the product, it reduces the weight of the product; the support nail 2 is arranged in the installation cavity 11. In addition, it is necessary to bundle the cables that need to be supported with a clamp 4 first, and an assembly hole is also provided on the clamp 4 for bundling the cables. In order to facilitate installation, the support nail 2 includes a first installation section 21 and a second installation section 22. The support nail 2 is divided into two installation sections, which can realize the separate installation of the support nail 2 and the clamp 4, and the support nail 2 and the support seat 1. During the installation process, there is no need to keep the installation position of the clamp 4 positioned, which simplifies the installation process and improves the installation efficiency. Specifically, the first mounting section 21 is connected to the mounting cavity 11 of the support base 1, and the first connecting section is fixed by an elastic pin 3 inserted through the first connecting section and the mounting base body. Connecting the first connecting section to the mounting cavity 11 of the support base 1 and fixing the first mounting section 21 in the mounting cavity 11 of the support base 1 with the elastic pin 3 are steps that can be easily completed with one hand, which is convenient for operation. The second mounting section 22 is located outside the support base 1 and is used for passing the assembly hole on the clamp 4 for fixing the wiring harness through and then locking it with a locking member. Specifically, the locking member is a locking nut 5, and the locking nut 5 can directly lock the clamp 4 on the second mounting section 22 by threading with the second mounting section 22. The assembly of the second mounting section 22 and the clamp 4 is also a process that can be easily completed with one hand. During installation, only one hand is needed to install the first mounting section 21 of the support nail 2 into the support base 1 and insert the elastic pin 3 to fix it. After completion, put the clamp 4 on the second installation section 22, and use the locking piece with one hand to lock the clamp 4 on the second installation section 22. The installation can be completed with one hand, which solves the problem of difficult installation of cables in a narrow space, improves the installation efficiency, and expands the application range of high support.

[0030] Reference Figure 3When the first mounting section 21 is installed in the support seat 1 and the second mounting section 22 supports the clamp 4 outside the support seat 1, the clamp 4 will be in direct contact with the support seat 1, causing the installation effect of the first mounting section 21 to directly affect the positioning and installation of the clamp 4. Therefore, a limiting boss 7 is further provided between the first mounting section 21 and the second mounting section 22, and the limiting boss 7 is used to limit the position between the support nail 2 and the support seat 1 and the clamp 4. Specifically, the limiting boss 7 is integrally formed with the first mounting section 21 and the second mounting section 22, and the limiting boss 7 includes a first limiting surface 71 connected to the first mounting section 21 and a second limiting surface 72 connected to the second mounting section 22, the first limiting surface 71 is used to limit the installation of the support nail 2 on the support seat 1, and the second limiting surface 72 of the limiting boss 7 is used to support and limit the clamp 4 on the support nail 2. The positioning and connection between the integrally formed first mounting section 21 and the first limiting surface 71, and between the second mounting section 22 and the second limiting surface 72, are more precise and stable, facilitating the precise positioning and stable installation of the support pin 2 and the clamp 4. Furthermore, when the first mounting section 21 of the support pin 2 is installed in the mounting cavity 11, the limiting boss 7, which is raised on the support pin 2, can serve as an auxiliary force member in conjunction with a dedicated tool when screwing the support pin 2 into the mounting cavity 11, further facilitating the installation of the high support.

[0031] Reference Figure 4 As one embodiment of the present invention, the support pin 2 can be a round support pin. Both the first mounting section 21 and the second mounting section 22 of the round support pin have external threads. A support nut 6 for threaded engagement with the first mounting section 21 is forcibly installed inside the support base 1. The support pin 2 is connected to the support base 1 through threaded engagement with the support nut 6, limiting the linear movement of the support pin 2 within the support base 1. At the same time, a pin hole that mates with the support base 1 is provided at the bottom of the first mounting section 21. The elastic pin 3 is inserted into the support base 1 and the support pin 2, further limiting the support pin 2 and ensuring the stability of the round support pin within the support base 1. The support structure of cables inside an aircraft is generally made by injection molding. The support seat 1 is made of non-metallic material. When the support pin 2 contacts and cooperates with the non-metallic support seat 1, when subjected to a large external force, the support effect is easily affected by the deformation of the support seat 1. The support nut 6 arranged in the installation cavity 11 of the support seat 1 is a metal part. When the support nut 6 made of metal contacts and cooperates with the support pin 2 made of metal, it can withstand stronger force, increase the support range of the high support, and further increase the stability of the high support during the support process.

[0032] In addition, in order to ensure the stability of the support nut 6 in the installation cavity 11, the outer wall surface of the support nut 6 is provided with a ridge 61. The ridge 61 on the outer wall of the support nut 6 is interference fit with the inner wall of the installation cavity 11, and the ridge 61 limits the axial movement of the support nut 6 in the installation cavity 11 of the support seat 1. Furthermore, the outer wall surface of the support nut 6 is also provided with axial knurling. The axial knurling increases the friction between the support nut 6 and the inner wall of the installation cavity 11. When the support pin 2 is subjected to a certain torque, it ensures that the support nut 6 matched with the support pin 2 will not rotate in the installation cavity 11, further increasing the stability of the connection of the support pin 2 in the support seat 1 and ensuring high support performance.

[0033] In this embodiment, the high support supports the wiring harness as follows:

[0034] S1: First, install the support base 1 with the support nut on the corresponding support frame in the aircraft;

[0035] S2: Then, screw the first mounting section 21 of the support nail into the mounting cavity of the support base with one hand and use the spring pin to limit the position;

[0036] S3: After assembling the cable on the clamp, use one hand to sleeve the assembly hole of the clamp 4 onto the second mounting section 22 of the support nail 2 protruding from the support seat;

[0037] S4: Finally, install the locking nut 5 on the second installation section 22 of the support nail 2 with one hand, and lock and limit the clamp 4 on the second installation section 22.

[0038] The above installation process can be achieved by single-handed operation in a small space, and the installation can be completed with one hand, which solves the problem of difficult cable installation in a small space, improves installation efficiency, and expands the scope of application of high support.

[0039] As another embodiment of the present application, the cross-section of the first mounting section 21 is non-circular. For the non-circular first mounting section 21, the shape of the mounting cavity 11 on the support seat 1 should be the same as the shape of the first mounting section 21, and it should cooperate closely with the first mounting section 21 to achieve the effect of circumferential anti-rotation. Therefore, in this embodiment, the first mounting section 21 is embedded in the mounting cavity 11 of the support seat 1, specifically using an insert injection molding process. After injection molding, the first mounting section of the support pin 2 is used as an insert and is set in the mounting cavity 11 on the support seat 1, thereby forming a connection between the first mounting section 21 of the support pin 2 and the support seat 1. Similarly, in order to avoid deformation of the injection-molded support seat 1 and affect the positioning of the support pin 2 in the mounting cavity 11, a pin hole that cooperates with the support seat 1 is further provided at the bottom of the first mounting section 21. The elastic pin 3 is inserted into the pin holes of the support seat 1 and the support pin 2, further limiting the first mounting section 21 and further ensuring the stability of the support pin 2 in the support seat 1.

[0040] The non-cylindrical first mounting section 21 can adopt a variety of shapes, such as a square, D-shaped, or triangular cross-section. These angular shapes can form a limited rotational barrier with the mounting cavity 11 of the same shape when subjected to force, thereby increasing the stability of the first mounting section 21 in the mounting cavity 11. In this embodiment, the high support supports the wiring harness as follows:

[0041] S1: First, install the support base 1 with support nails on the corresponding support frame in the aircraft;

[0042] S2: Then, with one hand, sleeve the assembly hole of the clamp 4 onto the second mounting section 22 of the support pin 2 protruding from the support seat;

[0043] S3: Finally, install the locking piece on the second installation section 22 of the support nail 2 with one hand, and lock and limit the clamp 4 on the second installation section 22.

[0044] The above installation process can be achieved by single-handed operation in a small space, and the installation can be completed with one hand, which solves the problem of difficult cable installation in a small space, improves installation efficiency, and expands the scope of application of high support.

[0045] Reference Figure 5 The bottom of the support base 1 has a mounting hole 8 for fixing the support base 1 to the support frame inside the aircraft. The axis of the mounting hole 8 is parallel or perpendicular to the axis of the support base 1, which facilitates the installation of the high support at different positions on the aircraft.

[0046] Reference Figure 5 The bottom of the support seat 1 is also provided with reinforcing ribs 9, which can ensure that the high support has higher structural strength and can meet the installation and use requirements of heavier cables and more extreme environments.

[0047] The above is only a preferred embodiment of the present invention. Any simple modification, equivalent change and modification made to the above embodiment by any technician familiar with this profession based on the technical essence of the present invention without departing from the scope of the technical solution of the present invention shall still fall within the scope of the technical solution of the present invention.
