Description

Technical Field

[0001] This utility model relates to the field of electrical connector manufacturing technology, specifically to an aviation plug connection device based on an adapter PCB board. Background Technology

[0002] In the traditional manufacturing process of multi-pin aviation connectors (e.g., 20 pins), each pin requires individual soldering of a wire. This process has several significant technical drawbacks:

[0003] (1) Low production efficiency: Due to the compact structure and dense pins of aviation connectors, efficient automated soldering processes such as wave soldering cannot be used. Even if automated soldering equipment is used, a large amount of manual assistance is still required, resulting in long production cycles and high labor costs. Secondly, the pins located in the inner ring are extremely difficult to solder, and the slightest carelessness may lead to poor soldering or short circuit with adjacent pins, resulting in scrap.

[0004] (2) Uncontrollable connection quality: Manual soldering carries a high risk of incomplete or false soldering. After soldering, since the aviation plug and cable have become a whole, the condition of the internal solder joints (such as whether there is insufficient solder) is difficult to be effectively inspected by non-destructive testing methods such as X-ray machines, resulting in poor product quality consistency and insufficient reliability.

[0005] (3) Extremely inconvenient to use and maintain: The aviation plug with a long fixed cable passes through the panel for installation, which is extremely inconvenient.

[0006] (4) Complex inventory management: Since equipment assembly requires cables of different lengths, the factory must design, produce and label each type of cable aviation plug of each length and specification, and store them separately, resulting in a large number of inventory units (SKUs), complex management, and a large amount of warehouse space occupied.

[0007] (5) Difficult and error-prone installation: When installing on the equipment panel, the aviation plug with a long cable needs to be passed through the panel, which limits the operating space and makes installation inconvenient. At the same time, the long cable can easily cause confusion and result in a high installation error rate.

[0008] (6) Cumbersome replacement and maintenance: If a damaged aviation plug needs to be replaced, the entire long cable must be disassembled together, which is a cumbersome process. During repeated disassembly and assembly, it is very easy for other solder joints to loosen or detach due to pulling, causing new faults.

[0009] Therefore, there is an urgent need for a multi-core aviation plug connection solution that can improve production efficiency, ensure product quality, and simplify installation and maintenance processes. Utility Model Content

[0010] In response to the problems in related technologies, this utility model proposes an aviation plug connection device based on an adapter PCB board to overcome the aforementioned technical problems in existing related technologies. The purpose of this utility model is to achieve a separate connection between the aviation plug and the cable by introducing an adapter PCB board and plug-in terminals, thereby solving a series of problems such as low production efficiency, difficulty in quality control, and inconvenience in use and maintenance caused by traditional soldering methods.

[0011] To achieve the above objectives, this utility model provides the following technical solution: an aviation plug connection device based on an adapter PCB board, comprising a multi-core aviation plug, wherein the multi-core aviation plug is provided with a plurality of aviation plug pins, an adapter PCB board is provided on one side of the multi-core aviation plug, the adapter PCB board is provided with a plurality of through holes, a pluggable terminal female socket is provided on one side of the adapter PCB board, the pluggable terminal female socket is provided with pluggable terminal female socket pins, the adapter PCB board is provided with pads, the adapter PCB board is provided with a plurality of first soldering holes, the pads are provided with a plurality of second soldering holes, and the through holes are connected to the first soldering holes through copper foil traces.

[0012] Preferably, one end of the aviation plug pin passes through a through hole and extends to the outside of the adapter PCB board, and the aviation plug pin and the adapter PCB board are soldered together.

[0013] Preferably, one end of the plug-in terminal female connector pin passes through solder hole two and solder hole one, and extends to the outside of the adapter PCB board, and the plug-in terminal female connector pin and the adapter PCB board are soldered together.

[0014] Preferably, the number of the aviation plug pins, through holes, and plug-in terminal female pins are the same.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) This utility model is an aviation plug connection device based on an adapter PCB board. By setting the adapter PCB board as the core adapter carrier, the discrete, manual point-by-point welding is transformed into automated PCB welding that can be carried out in batches. This makes the entire welding process compatible with mature PCB board automated welding processes (such as wave soldering and reflow soldering). This not only greatly improves production efficiency and realizes batch and standardized production, but also eliminates the instability of manual operation by combining automated welding process with online detection. This ensures the consistency, firmness and high reliability of each solder joint, greatly reduces quality risks such as cold solder joints and false solder joints, thereby improving the quality level of the entire connector and even the end product.

[0017] (2) This utility model is an aviation plug connection device based on an adapter PCB board. By separating the multi-core aviation plug with the integrated adapter PCB board from the cable assembly, a high degree of standardization and modularization is achieved. It can be used as an independent and universal standard component for unified production and inventory management. This completely changes the situation in the traditional model where multiple aviation plug assemblies need to be pre-installed for different cable lengths and different interface specifications. It greatly simplifies material coding, reduces inventory types and capital occupation, and reduces management complexity and warehousing costs.

[0018] (3) This utility model is an aviation plug connection device based on an adapter PCB board, which improves the convenience and efficiency of on-site installation and maintenance, reduces the installation difficulty and labor intensity, reduces installation errors caused by cable tangling and pulling, avoids the waste of the entire cable, significantly shortens the troubleshooting and repair time, and reduces the later maintenance cost.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] Example

[0026] Please see Figure 1-3This utility model proposes a technical solution for an aviation plug connection device based on an adapter PCB board: An aviation plug connection device based on an adapter PCB board includes a multi-core aviation plug 1, which has a plurality of aviation plug pins 2. An adapter PCB board 3 is provided on one side of the multi-core aviation plug 1. The adapter PCB board 3 has a plurality of through holes 4. A pluggable terminal female socket 5 is provided on one side of the adapter PCB board 3. The pluggable terminal female socket 5 has pluggable terminal female socket pins 6. The adapter PCB board 3 has a solder pad 7. The adapter PCB board 3 has a plurality of solder holes I. The solder pad 7 has a plurality of solder holes II. The through holes 4 are connected to the solder holes I through copper foil traces 8.

[0027] In this embodiment, the size and shape of the adapter PCB 3 are designed according to the tail size of the selected multi-core aviation plug 1 (e.g., 20-core). The position, diameter and spacing of the through hole 4 are completely matched with the aviation plug pins 2 on the multi-core aviation plug 1 to ensure that the aviation plug pins 2 can be smoothly inserted and positioned. The plug-in terminal female socket 5 adopts the existing technology. The plug-in terminal female socket pins 6 on the plug-in terminal female socket 5 are inserted into the corresponding soldering hole 1 on the adapter PCB 3. The copper foil traces 8 are etched. The through hole 4 and the plug-in terminal female socket pins 6 of the plug-in terminal female socket 5 are connected one-to-one to form a complete electrical path.

[0028] Please see Figure 1-2 As shown, one end of the aviation plug pin 2 passes through the through hole 4 and extends to the outside of the adapter PCB board 3. The aviation plug pin 2 and the adapter PCB board 3 are soldered together.

[0029] In this embodiment, the aviation plug pins 2 and the adapter PCB board 3 are soldered using a wave soldering machine.

[0030] Please see Figure 1-2 As shown, further, one end of the plug-in terminal female connector pin 6 passes through solder hole two and solder hole one, and extends to the outside of the adapter PCB board 3. The plug-in terminal female connector pin 6 and the adapter PCB board 3 are soldered together.

[0031] In this embodiment, the plug-in terminal female connector pin 6 and the adapter PCB board 3 are soldered using a wave soldering machine.

[0032] Please see Figure 1-3 As shown, the number of aviation plug pins 2, through holes 4, and plug-in terminal female pins 6 are the same.

[0033] The working principle of this utility model:

[0034] During production, the aviation plug pin 2 is inserted into the through hole 4 of the adapter PCB board 3, and the plug-in terminal female pin 6 is inserted into the soldering hole 1 of the adapter PCB board 3. The whole assembly is then sent into a wave soldering machine for soldering. After soldering, the multi-core aviation plug 1 and the plug-in terminal female 5 are firmly integrated on the adapter PCB board 3, forming an independent and standardized "aviation plug adapter module".

[0035] When used in the field, standard cable assemblies of the required length are prefabricated according to the equipment layout. One end of the cable assembly is crimped with a male connector that matches the female connector 5. During installation, the "aviation plug adapter module" is first installed on the equipment panel, and then the male connector of the cable assembly is directly inserted into the female connector 5 on the aviation plug adapter module.

[0036] This invention, through the ingenious design of the adapter PCB board 3, transforms the traditional "hard connection" of aviation plugs and cables into a "soft connection," solving a long-standing pain point in the industry. It brings revolutionary improvements in production efficiency, product quality, standardization, and ease of operation and maintenance, completely changing the traditional manual point-by-point soldering method, realizing automated production and reliable quality inspection, while standardizing aviation plugs, greatly simplifying inventory, installation, and maintenance processes, and improving production efficiency, product quality, and ease of operation and maintenance.
