Description

Technical Field

[0001] The utility model relates to the technical field of satellite communication equipment, in particular to a tool for pre-processing aviation antenna cables. Background Art

[0002] An aerial antenna is a device that converts radio wave signals from space into AC current signals in circuits. Its primary function is to connect radio wave signals in space with the AC current signals in circuits. One end of the antenna contacts the AC current signal in the circuit, and the other end contacts the radio wave signal in free space. This design enables the antenna to serve as a medium for converting radio wave signals from space into AC current signals in the circuit, ensuring the proper functioning of systems such as radio communications, broadcasting, radar, and navigation. Antennas play a crucial role in both transmitting and receiving modes: in transmitting mode, they convert high-frequency electromagnetic energy in transmission lines into electromagnetic waves in free space; in receiving mode, they convert electromagnetic waves in free space into high-frequency electromagnetic energy in transmission lines. This conversion function makes antennas an indispensable component of any wireless communication system.

[0003] With the advancement of communication technology, the precision requirements for aviation antennas are becoming increasingly stringent. Due to their irregular shape, the processing time for each structural component is long. Antennas are assembled from thirty to forty structural components, resulting in a complex assembly process and a correspondingly long assembly time. Due to the antenna's overall irregular shape, the cable routing is also very complex, with the connections and routing between cables not all aligned. Therefore, antenna cable processing typically occurs after the antenna is assembled, with workers soldering and routing the cables on the actual antenna. This process significantly impacts the overall antenna processing schedule and quality, creating quality risks. Furthermore, due to the long time between the connection and assembly of the two antennas, consistency in cable routing, cable bundling methods, and the number of nylon ties is poor. Furthermore, processing the cables on the antenna makes accurate measurement and definition difficult, posing significant risks to cable processing quality and severely impacting product quality and efficiency.

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] An aviation antenna is a three-dimensional precision device with a complex structure. To operate, the antenna must rotate along the X and Y axes. Signals are transmitted through cables connecting components in different positions. The cables are not routed in the same plane, so cable processing can only be done on the antenna after it is assembled. This process greatly affects product delivery progress and also poses certain quality risks to the product's welding quality.

[0023] Combine Figure 1 The utility model provides a tool for pre-processing aviation antenna cables, which includes a plane structure model 10, on which a wiring groove 20 and a through-hole O-shaped mark 30 are provided;

[0024] The planar structure model 10 is designed to simulate a three-dimensional antenna and is used for cable processing and storage;

[0025] The routing groove 20 simulates the actual routing mode of the cable, and the cable is routed along the routing groove 20;

[0026] The through-hole O-shaped mark 30 is designed based on the nylon wire tie for bundling cables, and the number and position of the nylon wire tie are fixed.

[0027] Furthermore, the plane structure model 10 is made of nylon 1010 material.

[0028] Furthermore, the planar structure model 10 is designed into a planar shape, the three-dimensional antenna structure is spread outward into a plane, and the cables and wiring are processed on the plane.

[0029] Furthermore, all cables are processed and fixed in the routing groove 20 .

[0030] Furthermore, the planar structure model 10 is provided with connector positions at both ends of the cable, and the cable processing process card, tooling, and components are unified in name, and the component cable connection position identification is marked on the tooling.

[0031] Furthermore, all routing corners are designed to be rounded to prevent the chamfers from abrading the cables during processing.

[0032] Furthermore, in the wiring groove 20, the wire tie position is designed on the outside of the wiring groove 20 with an O-shaped through hole marked as an O-shaped sinking hole. Nylon wire ties are required to be used to bundle the cables at this position to ensure the consistency of the wire tie position and the number of wire ties.

[0033] Furthermore, the antenna cables are welded and routed on the tooling, and the pre-fabricated cable connectors are directly assembled to the corresponding positions of the antenna components.

[0034] Combine Figure 2 The utility model of the aviation antenna cable pre-processing tooling design method includes the following steps:

[0035] Step 1: simulate the three-dimensional antenna and design the plane structure tooling;

[0036] Step 2: Analyze the antenna structure and establish a connection model for antenna cables to components at different locations;

[0037] Step 3: Based on the antenna cable connection model, simulate the actual cable routing method and design a routing groove 20 on the tooling;

[0038] Step 4: For the nylon ties that need to be used to bundle the cables, design through-hole O-shaped marks 30 on the tooling according to the number and position of the nylon ties;

[0039] Step 5: Assemble the pre-fabricated cable connectors directly to the corresponding positions of the antenna components, and complete the antenna cable welding and routing on the flat tooling.

[0040] As a specific example, the tooling is made of nylon 1010 material, which is light, not easily damaged, easy to carry and wear-resistant.

[0041] As a specific example, the three-dimensional simulated antenna described in step 1 is designed to design a planar structure tooling as follows:

[0042] The tooling is designed into a flat shape, the three-dimensional antenna structure is spread out into a plane, and the cables and traces are processed on the plane.

[0043] As a specific example, the antenna structure is analyzed in step 2, and a connection model of the antenna cable to components at different positions is established, as follows:

[0044] The antenna device has a three-dimensional structure and needs to rotate along the X and Y axes to work. Cables are used to connect components in different positions to transmit signals. Because the cable routes are not in the same plane, a connection model for the antenna cables to components in different positions is established based on the antenna structure.

[0045] As a specific example, in step 3, based on the antenna cable connection model, the actual cable routing is simulated and the routing groove 20 is designed on the tooling, as follows:

[0046] Design the positions of the connectors at both ends of the cable, combine the unified names of the cable processing process cards, tooling, and components, and mark the component cable connection parts on the tooling to ensure that there are no errors in the routing.

[0047] As a specific example, all routing corners on the tooling are designed to be rounded to prevent the chamfers from wearing out the cables during cable processing.

[0048] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. Example

[0049] Combine Figure 3 The aviation antenna provided in this embodiment includes a first module 1 to a sixth module 6, and the cable connection relationship thereof is as follows:

[0050] The third module 3 has three connectors, A1, A2, and A3. The A1 connector connects to the fourth module 4, the sixth module 6, the first module 1, and the second module 2, respectively. The A2 connector connects to the fifth module 5 and the first module 1, respectively. The A3 connector connects to the second module 2 and the fourth module 4, respectively. The sixth module 6 has a connector connected to the first module 1. As can be seen, a single cable can be routed along the X, Y, and Z axes, with no clear path. Without a physical antenna, it's difficult to plan the routing path, and the length is uncontrollable.

[0051] Figure 4 This is the routing method of this cable on the tooling, as follows:

[0052] The cable runs from A1 on the third module 3 along the groove to the fourth module 4, the first module 1, the fifth module 5, and the second module 2. The cable runs from A1 to A5 to the fourth module 4, A1 to A6 to the fifth module 5, A1 to A7 to the first module 1, and A1 in the opposite direction to A9 to the second module 2. The cable runs from A2 on the third module 3 along the groove to the fifth module 5 and the first module 1. The cable runs from A2 to A6 to the fifth module 5, and then circles around the concave groove at A7 to the first module 1. The cable runs from A2 to A1 along the groove to the second module 2 and the fourth module 4. The cable runs from A3 to A9 to the second module 2, and along the outermost groove of the tooling to A5 to the fourth module 4. The cable runs from the sixth module 6 along the groove to the first module 1 to the first module 1. All cables can be soldered and routed on the flat tooling.

[0053] Since the distance the cable is routed along the groove is the actual length of the cable, the consistency and accuracy of all welded cables, routing methods and cable lengths on the tooling are ensured; the O-shaped mark on the outside of the groove is where the nylon ties of the cable are tied, ensuring the consistency of the position and quantity of the nylon ties of the cable; all corners of the cable are rounded to ensure the reliability of the processed cable quality; since the cable processing is completed on the same plane, it is convenient for processing and welding, and it is also convenient to measure the accuracy of the cable definition, thereby improving the reliability of product quality.

[0054] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
