Description

Technical Field

[0001] This utility model belongs to the technical field of aircraft electrical wiring interconnection system, and relates to the technical field of electrical interconnection system wiring installation design, and in particular to a series of mounting brackets for isolating wire harness spacing. Background Technology

[0002] Aircraft electrical wiring interconnection systems specify minimum spacing requirements between harnesses, between harnesses and structures, and between harnesses and conduits based on electromagnetic compatibility and functional classifications. Wiring installation designs must meet these minimum spacing isolation distance requirements. Furthermore, while meeting isolation distance requirements, electrical wiring should be laid parallel as much as possible during design and installation to minimize crossings. In areas on the aircraft where space exists, a new series of mounting brackets for isolating harnesses is needed to quickly achieve channel isolation in order to meet the required isolation spacing between harnesses. Utility Model Content

[0003] Purpose of the utility model: This utility model provides a series of mounting brackets for isolating wire harness spacing, which can solve the requirements of different isolation spacing between wire harnesses with different channel codes on the machine. This series of mounting brackets can meet the isolation distance requirements of 25mm, 75mm, 100mm and 150mm in the wire harness isolation specification, and solve the problems of compatibility interference or arcing that may be caused by insufficient isolation spacing between wire harnesses.

[0004] The technical solution adopted in this invention is: The system includes a support body, which has a fixed end for connecting to the aircraft structure. The support body also has one or two wire harness clamp fixing ends, each with a clamp. When the support body has two wire harness clamp fixing ends, the distance between the two clamp fixing ends meets the wire harness isolation distance requirement. The distance between the plane containing the wire harness clamp fixing ends and the fixed end connected to the aircraft structure meets the aircraft wire harness isolation distance requirement.

[0005] Furthermore, the bracket body is a T-shaped wire harness mounting bracket, which includes a horizontal end and a vertical end. The horizontal end has wire harness clamp mounting holes at both ends for mounting wire harness clamps. The vertical end is a fixed end with rivet mounting holes. The T-shaped wire harness mounting bracket is fixed to the aircraft structure by passing rivets through the rivet mounting holes.

[0006] Furthermore, reinforcing ribs are provided between the vertical and horizontal ends of the T-shaped wire harness mounting bracket.

[0007] Furthermore, the distance from the wire harness clamp mounting holes at both ends of the horizontal end of the T-shaped wire harness mounting bracket to the vertical end meets the wire harness isolation requirement of not less than 75mm, and the distance between the wire harness clamp mounting holes at both ends of the horizontal end meets the wire harness isolation requirement of not less than 150mm.

[0008] Furthermore, the bracket body is an L1 type wire harness mounting bracket. The horizontal end of the L1 type wire harness mounting bracket is longer than the vertical end. The horizontal end is provided with a wire harness clamp mounting hole for installing wire harness clamps. The vertical end is a fixed end, and the fixed end is provided with a rivet mounting hole. The T-type wire harness mounting bracket is fixed to the aircraft structure by passing a rivet through the rivet mounting hole.

[0009] Furthermore, a reinforcing rib is provided between the vertical end and the horizontal end of the L1 type wire harness mounting bracket.

[0010] Furthermore, the distance from the wire harness clamp mounting hole at the horizontal end of the L1 type wire harness mounting bracket to the vertical end meets the wire harness isolation requirement of not less than 75mm.

[0011] Furthermore, the bracket body is an L2 type wire harness mounting bracket. The horizontal end of the L2 type wire harness mounting bracket is shorter than the vertical end. The horizontal end is provided with a wire harness clamp mounting hole for mounting wire harness clamps. The vertical end is a fixed end, and the fixed end is provided with a rivet mounting hole. The T-type wire harness mounting bracket is fixed to the aircraft structure by passing a rivet through the rivet mounting hole.

[0012] Furthermore, a reinforcing rib is provided between the vertical end and the horizontal end of the L2 type wire harness mounting bracket.

[0013] Furthermore, the distance from the wire harness clamp mounting hole at the horizontal end of the L2 type wire harness mounting bracket to the vertical end meets the wire harness isolation requirement of not less than 25mm.

[0014] The beneficial effects of this utility model are: This utility model provides a series of mounting brackets for isolating wire harness spacing. These brackets can be used for the fixed installation of wire harness clamps in areas such as wings. By using brackets of different specifications within the series, the physical isolation spacing between each wire harness channel can be guaranteed, avoiding safety hazards such as electromagnetic compatibility and electric arc caused by insufficient isolation spacing. At the same time, the serialized design makes the bracket form simple and consistent, which is relatively friendly to bracket manufacturers in terms of material preparation and mold making. Attached image description: Figure 1 This is a schematic diagram of a T-type wire harness mounting bracket structure; Figure 2 This is a schematic diagram of the L1 type wire harness mounting bracket structure; Figure 3 This is a schematic diagram of the L2 type wire harness mounting bracket structure. Detailed implementation method: The present invention will be further described below with reference to the accompanying drawings: This utility model proposes a bracket body, which is provided with a fixed end for connecting to the aircraft structure. The bracket body is also provided with one or two wire harness clamp fixing ends, each with a clamp. When the bracket body is provided with two wire harness clamp fixing ends, the distance between the two clamp fixing ends of the bracket body meets the wire harness isolation distance requirement. The distance between the plane containing the wire harness clamp fixing ends and the fixed end connected to the aircraft structure on the bracket body meets the aircraft wire harness isolation distance requirement.

[0015] The series of mounting brackets proposed in this utility model include T-type wire harness mounting bracket 101, L1-type wire harness mounting bracket 102, and L2-type wire harness mounting bracket 103.

[0016] The T-type wire harness mounting bracket 101 is machined from aluminum alloy. It has three rivet mounting holes, allowing it to be fixed to the structural metal surface using 3mm diameter rivets. The T-type bracket 101 also has two clamp mounting holes, allowing for the selection of clamps of different specifications based on the actual wire harness diameter. The clamps are installed by screws and nuts that mate with the clamp mounting holes. The appropriate installation angle of the clamp can also be selected considering the routing of the wire harness channel. For the L1 type wire harness mounting bracket 102, the L1 type bracket 201 is machined from aluminum alloy. The bracket has three rivet mounting holes, which can be used to fix the L1 type bracket 201 to the structural metal surface using rivets with a diameter of 3mm. The L1 type bracket 201 has one clamp fixing mounting hole, and different specifications of clamps can be selected for fixing according to the actual wire harness diameter. The clamp is installed by screws and nuts fasteners that cooperate with the wire harness clamp mounting hole. At the same time, the appropriate installation angle of the wire harness clamp can be selected considering the routing of the wire harness channel.

[0017] For the L2 type wire harness mounting bracket 103, the L2 type bracket 301 is machined from aluminum alloy. The bracket has three rivet mounting holes, which can be used to fix the L2 type bracket 301 to the structural metal surface using rivets with a diameter of 3mm. The L2 type bracket 201 has one clamp fixing mounting hole. Different specifications of clamps can be selected for fixing according to the actual wire harness diameter. The clamp is installed by screws and nuts fasteners that cooperate with the wire harness clamp mounting hole. At the same time, the appropriate installation angle of the wire harness clamp can be selected considering the routing of the wire harness channel.

[0018] All brackets can be used flexibly and can be installed on both sides of the mounting surface using the inherent installation methods of L1 and L2 to achieve the purpose of isolation.

[0019] This series of mounting brackets are machined aluminum alloy parts, material grade 7050, 1.6mm thick. The surface is chromate anodized, then coated with two layers of MS 25D05 primer (2 layers, 20μm~45μm), and one layer of MS 25D06 topcoat (1 layer, 51μm~76μm). Each bracket has three 3.1mm diameter rivet mounting holes, allowing for secure mounting to the structure using rivets of the corresponding specifications. Reinforcing ribs are added at the bends of the brackets to reduce the possibility of stress cracking. Clamping mounting holes, 5.1mm in diameter, are provided at the ends of the brackets for securing wire harnesses with matching screws and nuts. The clamps can be rotated at a certain angle within the mounting plane according to actual usage requirements.

[0020] The harness isolation distances differ between different channel codes, as shown in the table below: Table 1 Channel Category Spacing Table

[0021] In accordance with isolation specifications, the series of mounting brackets is designed with three specifications: T-type brackets, L1-type brackets, and L2-type brackets. The difference between the three types of brackets lies in the distance between the center line of the clamp fixing hole and the plane where the rivet mounting hole is located, with specifications of 150mm, 75mm, and 25mm respectively. The bracket corresponding to the required channel spacing should be used for installation.

[0022] After the T-shaped bracket is installed, clamps are installed at the clamp fixing holes at both ends of the T-shaped bracket and the wire harness is laid. The two wire harnesses laid can meet the 150mm spacing requirement.

[0023] After the L1 type bracket is installed, the clamps are installed on the clamp fixing holes and the wire harness is laid. This ensures that the wire harness is 75mm away from the plane where the rivet is installed. Other channel code wire harnesses can be installed on the other side of the plane, with a minimum 75mm spacing requirement.

[0024] The L1 is used in conjunction with the L2 bracket. The L1 bracket and the L2 bracket are fixed on both sides of the mounting plane respectively. The clamps are installed on the mounting holes of the two brackets and the wire harness is laid, which can achieve the requirement of 100mm isolation distance between the wire harnesses.

[0025] After the L2 type bracket is installed, clamps are installed on the clamp fixing holes of the L2 type bracket and the wire harness is laid. This ensures that the wire harness is 25mm away from the plane where the rivet is installed. Other channel code wire harnesses can be installed on the other side of the plane, with a minimum 25mm spacing requirement.

[0026] Two L2 type brackets are used together. Two L2 type brackets are fixed on both sides of the mounting plane. The brackets are fixed with clamps in the mounting holes and the wire harness is laid. The 50mm isolation distance between the wire harnesses can be achieved.

[0027] In summary, the present invention provides a series of mounting brackets for isolating wire harness spacing, which can be used for the fixed installation of wire harness clamps in areas such as wings. At the same time, by using brackets of different specifications in combination within the series, the physical isolation spacing between each wire harness channel can be guaranteed, avoiding safety hazards such as electromagnetic compatibility and electric arc caused by insufficient isolation spacing. In addition, the serialized design makes the bracket form simple and consistent, which is relatively friendly to bracket manufacturers in terms of material preparation and mold making.
