Description

Technical Field

[0001] This utility model relates to the field of aviation plug welding technology, specifically to an aviation plug welding fixture. Background Technology

[0002] Aviation connectors, as highly reliable electrical connectors, are widely used in electronic communications, aerospace, medical instruments, military equipment, and communication base stations. They are often used in conjunction with cables to establish electrical signal connections between various communication modules within a device, making them an indispensable key component in the overall system. The soldering quality between the aviation connector and the cable directly affects communication quality, signal transmission stability, and the operational reliability of the entire device.

[0003] Because aviation connectors are typically cylindrical, they are difficult to securely fix during cable welding, and are prone to slight displacement during the welding process. This displacement can lead to defects such as incomplete soldering or detachment of the lead terminals, and in severe cases, it can cause poor contact, increased resistance, and consequently reduce the electrical performance of the connector, affecting the long-term stable operation of the equipment. Existing fixing devices are mostly designed for specific connector structures, lacking versatility and unable to adapt to different models or sizes of aviation connectors. This results in frequent fixture changes when changing models, increasing preparation time and costs. Furthermore, the instability of the connector during the welding process significantly reduces welding efficiency and increases operational difficulty, especially in single-person operations or multi-station assembly line welding scenarios, where the problem is even more pronounced.

[0004] In high-reliability scenarios such as communication equipment, the requirements for welding aviation plugs to cables are particularly stringent. The secure fixing of the plug becomes a key factor affecting welding quality and efficiency. Therefore, there is an urgent need for an aviation plug fixing device that is simple in structure, easy to use, securely fixed, and highly adaptable to improve the stability, efficiency, and final connection reliability of welding operations. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide an aviation plug welding fixation device. This device uses a strap and an elastic element to continuously wrap and press the aviation plug, avoiding plug displacement caused by vibration or human operation during the welding process, significantly reducing defects such as incomplete welding and desoldering, improving welding quality, and effectively solving the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an aviation plug welding and fixing device, comprising a base, a strap, an L-shaped sliding plate, and a screw. One end of the strap is fixed to the base by a screw, and the other end of the strap is connected to an elastic element. The other end of the elastic element is connected to the L-shaped sliding plate. The elastic element provides tension to the strap, keeping it taut at all times to prevent loosening when fixing the aviation plug. The L-shaped sliding plate is slidably connected to the base. A support plate is provided on one side of the L-shaped sliding plate. One end of the screw passes through the support plate and is rotatably connected to the side of the L-shaped sliding plate. A side adjustment plate is provided on the side of the base. An adjusting pressure plate is provided on the side of the adjusting plate. The adjusting pressure plate presses on the strap and its position can be adjusted, thereby adjusting the gap between the adjusting pressure plate and the screw. This can meet the fixing work of different specifications of aviation plugs and improve the practicality of the device. A cavity for fixing the aviation plug is formed between the adjusting pressure plate and the screw. Specifically, the aviation plug is placed under the strap and wrapped around it. The screw and adjusting pressure plate are used to press the strap. The elastic element provides elastic tension to the strap. Under the action of tension, the aviation plug is fixed to the base by the restriction of the screw and adjusting pressure plate.

[0007] By using the tension of the elastic element, the aviation plug wrapped by the strap is securely fixed, allowing for the welding of cables. This fixator is applicable to various electronic communication fields, such as aerospace, medical, and communication base station manufacturing, where the aviation plug needs to be fixed to achieve reliable welding with the cable. This utility model improves the welding quality and efficiency of the product; it also provides convenience for a single person to reliably weld various aviation plugs to cables.

[0008] Furthermore, iron nails are provided on the left side of the elastic element. The iron nails are bent at 90° to press down on the strap, but maintain a distance of 1mm from the strap. This gap ensures the movement of the strap. Several iron nails are provided, staggered from each other, with a spacing of 4-10mm. The iron nails restrict the strap, reduce the force on the adjusting plate, and make the structure more stable. At the same time, the strap adjusts and fixes the position of the elastic element's tension, thereby adjusting the tightness of the fixed aviation plug.

[0009] Furthermore, the elastic element is a rubber band or a tension spring.

[0010] Furthermore, the base has a T-shaped groove on its side, in which a T-bolt is installed. The T-bolt, in conjunction with a nut, fixes the side adjustment plate. The side adjustment plate can be adjusted by loosening the nut, thus meeting the needs of fixing aviation plugs of different specifications.

[0011] Furthermore, a positioning post is provided on the horizontal surface of the L-shaped slide, and a perforated connecting plate is provided on the other end of the elastic element. The perforated connecting plate is fitted onto the positioning post. When the elastic element is a rubber band, it can be connected to the perforated connecting plate or connecting strap through cable ties. When the elastic element is a tension spring, it can be hung on the perforated connecting plate or connecting strap. The specific connection method is selected according to the actual situation.

[0012] Furthermore, the screw is threadedly connected to the support plate, and a handwheel is provided at the other end of the screw. By rotating the handwheel, the L-shaped sliding plate can be moved, and the tension of the strap can be adjusted by the elastic element, which improves the practicality of the device. This fixture is simple to operate, convenient to use, safe and reliable, and improves welding efficiency and welding quality.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model achieves multi-point support and flexible wrapping fixation of the aviation plug by setting a strap, elastic element and L-shaped sliding plate on the base, which can effectively avoid the problem of plug displacement during the welding process; the strap maintains constant tension under the action of elastic element, and works with adjusting pressure plate and screw to press and fix the plug, so that the plug is in a stable state during the welding process, thereby significantly improving the reliability and consistency of the welding point and reducing quality risks such as poor welding and false welding.

[0014] 2. This device has good adjustability and adaptability. The adjusting plate and sliding component can be positioned and adjusted according to the plug size, which is suitable for welding various types of aviation plugs and avoids the time waste caused by frequent clamp changes. The nail limiting structure further enhances the stability of the strap and disperses the structural stress, improving the service life of the device. The overall device is compact and easy to install, making it suitable for assembly line operations or on-site maintenance.

[0015] 3. The aviation plug welding fixture of this utility model can effectively improve welding efficiency, support single-person operation, reduce dependence on manual technical skills, and is especially suitable for applications with high welding quality requirements.

[0018] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Example 1

[0019] Please see Figure 1-3 This utility model provides a technical solution: an aviation plug welding and fixing device, including: a base 12, a strap 9, an L-shaped sliding plate 4, a screw 3, a support plate 2, a side adjustment plate 8, an adjustment pressure plate 16, an elastic element 6, an iron nail 7, a T-shaped sliding groove 11, a T-shaped bolt 15, a nut 14, a positioning post 5, a connecting plate with holes 13, and a hand plate 1, etc.

[0020] The base 12 is an integral structural support platform used to fix all components and support the aviation plug. A T-shaped groove 11 is provided on the base 12, and a sliding T-bolt 15 is provided in the groove 11. The T-bolt 15 cooperates with the nut 14 to fix the side adjustment plate 8. During adjustment, the position of the adjustment plate 8 can be finely adjusted by loosening the nut 14 to adapt to aviation plugs of different sizes.

[0021] The first end of the strap 9 is fixed to the base 12 by a screw 10, and the other end is connected to one end of the elastic element 6. The elastic element 6 can be a rubber band or a tension spring, and the other end is connected to the L-shaped slide plate 4. To ensure the reliability of the connection, one end of the elastic element 6 is connected to the strap 9 through a perforated connecting plate 13. The perforated connecting plate 13 is sleeved on the positioning post 5 located on the horizontal surface of the L-shaped slide plate 4. If it is a rubber band connection, it can be fixed with a cable tie. If it is a tension spring connection, it is hung on the perforated connecting plate 13 or the strap 9.

[0022] The L-shaped slide plate 4 is slidably mounted on the base 12, and the sliding relationship can be adjusted by the screw 3. One end of the screw 3 is connected to the support plate 2 by a thread, and the other end is equipped with a handwheel 1. The user drives the screw 3 to rotate by rotating the handwheel 1, thereby driving the L-shaped slide plate 4 to move back and forth along the slide rail. This structure helps to adjust the tension of the elastic element 6, thereby realizing the tightness adjustment when the strap 9 covers the aviation plug.

[0023] The adjusting pressure plate 16 is located on the outer surface of the side adjusting plate 8 and is used to generate a vertical clamping force on the strap 9. A variable clamping cavity is formed between the strap 9 and the adjusting pressure plate 16. Users can adjust the position of the adjusting pressure plate 16 to adjust the size of the clamping cavity according to the different specifications of aviation plugs, thereby firmly wrapping the aviation plug and fixing its position.

[0024] To further improve the stability of the strap 9, several iron nails 7 are provided on the left side of the elastic element 6. The iron nails 7 are bent at 90° to press down on the strap 9, but maintain a gap of about 1mm from the strap 9 to ensure that the strap can still move freely under tension. The multiple iron nails 7 are staggered in the length direction with a spacing of 4-10mm, thereby guiding and limiting the strap, reducing the stress on the adjusting pressure plate 16, and enhancing the overall structural stability.

[0025] In use, place the aviation plug under the strap 9, pull the L-shaped slide plate 4 to tighten the elastic element 6, and drive the strap 9 to tightly wrap the plug. Use the adjusting pressure plate 16 and screw 10 to fix it vertically, thereby ensuring that the plug is stably in place. After positioning, cable welding can be performed to ensure welding quality and efficiency.

[0026] This structure is particularly suitable for operating environments that require stable fixation of various types of aviation plugs. It is widely used in electronic communication fields such as aerospace, medical, and communication base stations. It has the advantages of simple structure, convenient operation, accurate positioning, and strong adaptability, effectively improving the welding quality and production efficiency of aviation plugs.

[0027] In this embodiment, for aviation plugs with larger diameters and longer lengths, the original structure is adjusted as follows to ensure fixing stability and welding accuracy: The base 12 is wider and longer to accommodate the plug size and enhance the overall load-bearing capacity; The cable tie 9 has been changed to a wider nylon material, with its width increased to 25mm, to enhance the coverage of extra-large plugs; The elastic element 6 uses a heavy-duty tension spring with a tension of 15~25N to ensure that the strap 9 has sufficient retraction force. The L-shaped slide plate has ball grooves added to the contact surface of the four guide rails, and adopts a double slide rail structure to improve sliding stability; The thickness of the adjustable pressure plate 16 is increased to 5mm, and it is made of aluminum alloy to prevent deformation. The adjustment range of the side adjustment plate 8 is extended to more than 50mm, which can meet the universal plug compatibility requirements.

[0028] Using this structure, even large-sized aviation plugs can maintain a stable and wobbly position after placement and tightening, providing conditions for high-quality soldering.

[0029] The foregoing has shown and described the basic principles, main features and advantages of this utility model. Various changes and modifications may be made to this utility model without departing from the spirit and scope thereof, and all such changes and modifications fall within the scope of this utility model as claimed.
