Description

Technical Field

[0001] This utility model relates to the field of aviation equipment technology, specifically a connector welding bracket used in aircraft overhaul processes. Background Technology

[0002] During aircraft overhaul, cable repair is divided into on-board cable repair and off-board cable repair. Off-board cables are those that can be completely disassembled and removed from the aircraft. During the overhaul, these cables are repaired off the ground and then reinstalled on the aircraft. On-board cables are those left on the aircraft after disassembly. These cables are more difficult to remove off the aircraft and are therefore repaired on-board. There are two methods for connecting connectors and wires on aircraft: crimping and soldering. Soldering is more complex and requires higher operator skill to ensure soldering quality; it necessitates the use of a soldering iron and a soldering stand.

[0003] Existing welding brackets used in aircraft manufacturing and repair are mostly bulky and designed for off-aircraft repairs. For cables left on board, the limited space makes welding connectors difficult, and the constraints of cable length and space often result in brackets lacking support. Furthermore, current brackets are only designed for low-frequency connectors or a small number of other types of connectors, and cannot meet the welding requirements of RF connectors, unidirectional sockets / pins, and connector handles during aircraft overhauls, thus failing to meet current repair needs. Welding of aircraft connectors demands high standards for solder joints, requiring no cold solder joints, burrs, sharp protrusions, debris, flux buildup, broken wires, voids, cracks, pinholes, or weld beads.

[0004] For many wires that are difficult to solder due to insufficient skill, operators often solder in the same position for extended periods to ensure soldering quality. Excessive soldering time in a single session can easily damage the cable insulation and cause the wire core to oxidize, harden, and become brittle. Furthermore, the angled supports used can cause flux to flow into the connector, severely affecting its electrical performance. For RF connectors, connector handles, and unidirectional sockets / pins lacking fixed supports, soldering can only be done by clamping them with tools such as pliers, which is extremely inconvenient. Because of the lack of secure fixation, solder on RF connectors is prone to flowing to other areas, forming solder lumps or sharp protrusions, causing interference and degrading the connector's transmission performance. Utility Model Content

[0005] To address the aforementioned problems, this utility model proposes a connector welding bracket for use in aircraft overhaul processes.

[0006] A connector welding bracket for use in aircraft overhaul processes, comprising:

[0007] Welding brackets are used to clamp connectors during the welding process, secure wires, and prevent flux from flowing into the connector during welding.

[0008] The welding bracket fixing device provides overall support and fixation for the welding bracket.

[0009] Soldering iron holders are used to hold soldering irons during the soldering process, and can also be equipped with a timing function to solve the problem of excessively long single soldering time.

[0010] Furthermore, the welding bracket includes a connector clamp, a frame body for mounting the connector clamp, a wire clamping universal arm that slides up and down along the side of the frame body, a wire clip located at the end of the wire clamping universal arm and fixed in position by a fastening nut, a slot for placing wires in the lower half of the wire clip, a bubble level located at the bottom of the frame body, a universal arm fixing mounting hole mounted on the welding bracket by a fixing screw, and a base mounting hole located on the frame body.

[0011] Furthermore, the connector clamp includes an upper connector clamp and a lower connector clamp, and the lower connector clamp is fixed to the frame body by a second fastening nut.

[0012] Furthermore, the connector fixture is provided with an RF connector clamping slot, a low-frequency connector clamping slot, a unidirectional socket / pin clamping slot, and a wiring handle clamping slot.

[0013] Furthermore, the welding bracket fixing device includes a base, a base pad fixed to the base by fixing screws, a multi-functional clamp that cooperates with the base, and several sets of universal arms of various specifications connected to the multi-functional clamp.

[0014] Furthermore, the multi-functional clamp includes an upper part of the multi-functional clamp and a lower part of the multi-functional clamp installed at the end of the universal arm.

[0015] The beneficial effects of this utility model are as follows: By using various components in combination, this utility model solves the problem of soldering low-frequency connectors, radio frequency connectors, unidirectional sockets / pins, and connector handles in various scenarios during overhaul. At the same time, by using a bubble level and a design timing device to modify the traditional soldering iron stand, it solves the problem of cable damage or connector electrical performance degradation caused by flux inflow and overtime soldering. It efficiently and conveniently completes the soldering of connectors during overhaul, improves the soldering qualification rate, and ensures the quality of repair. Attached Figure Description

[0034] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the utility model will be further described below.

[0035] like Figures 1 to 16 As shown, a connector welding bracket used in aircraft overhaul processes includes:

[0036] Welding bracket 1 is used to clamp the connector during the welding process, fix the wires, and solve the problem of flux flowing into the connector during the welding process;

[0037] The welding bracket fixing device 2 provides overall support and fixation for the welding bracket 1.

[0038] Soldering iron stand 3 is used to place the soldering iron during the soldering process, and a timing function can be added according to the usage scenario and requirements to solve the problem of excessively long single soldering time during the soldering process.

[0039] This utility model solves the problem of soldering low-frequency connectors, radio frequency connectors, unidirectional sockets / pins, and connector handles in various scenarios during overhaul by using various components in combination. At the same time, it modifies the traditional soldering iron stand by using a bubble level 108 and a design timing device 304 to solve the problem of cable damage or connector electrical performance degradation caused by flux inflow and overtime soldering. It efficiently and conveniently completes the soldering of connectors during overhaul, improves the soldering qualification rate, and ensures the quality of maintenance.

[0040] Figure 11 In this context, 'I' represents the weldable area.

[0041] The welding bracket 1 includes a connector clamp, a frame body 101 for mounting the connector clamp, a wire clamping universal arm 104 that slides up and down along the side of the frame body 101, a wire clip 105 located at the end of the wire clamping universal arm 104 and fixed in position by a fastening nut 106, a slot 107 in the lower half of the wire clip 105 for placing wires 116, a bubble level 108 located at the bottom of the frame body 101, a universal arm fixing mounting hole 112 mounted on the welding bracket 1 by a fixing screw 205, and a base mounting hole 113 located on the frame body 101. The solder joint 117 on the low-frequency connector is used to weld the wires 116, which pass through the slot 107, to the solder joint 117 after stripping the insulation layer according to process requirements, according to welding requirements. In use, the fixing screw 203 is inserted into the base mounting hole 113, and then the fastening nut 204 is tightened to fix the welding bracket 1 and the base 201.

[0042] The wire clamping universal arm 104 can slide up and down along the side of the welding bracket frame body 101. When it slides to the appropriate position, it is fixed with the fastening nut 106.

[0043] The wire clamp 105 at the end of the wire clamping universal arm 104 is used to clamp the wire during welding. When in use, the wire clamping universal arm 104 itself can be bent and adjusted to a suitable position.

[0044] The wire clamp 105 can clamp 0.2mm during the welding process. 2 ~1.5mm 2 If the wire and the universal arm 104 clamping wire are not needed during welding, they can be slid and bent to a position that does not obstruct welding.

[0045] The bottom of the welding bracket frame body 101 is equipped with a bubble level 108 to control the tilt angle of the welding bracket. When the bubble is in the "weldable zone", the angle meets the welding requirements and can prevent flux from flowing into the connector.

[0046] The connector clamp includes an upper connector clamp 102 and a lower connector clamp 103. The lower connector clamp 103 is fixed to the frame body 101 by a second fastening nut 114.

[0047] The lower 103 of the connector fixture is provided with an RF connector clamping slot 109, a low-frequency connector clamping slot 110, a unidirectional socket / pin clamping slot 115, and a wire handle clamping slot 111. Considering the thickness of the wire handle, the wire handle clamping slot 111 is only slotted on the lower 103 of the connector fixture, and the corresponding position on the upper 102 of the connector fixture is a plane to ensure that the wire handle can be stably clamped when soldering the wire handle.

[0048] The low-frequency connector clamping slot 110 can be used for soldering low-frequency connectors with diameters of 8mm to 80mm. The RF connector clamping slot 109 has a stepped groove, with the front end used to clamp the main body of the connector and the rear end used to press the nut part of the RF connector. This slot can be used for soldering SMA type RF connectors with a minimum diameter of about 5mm. For other models of RF connectors with larger sizes or other structural forms, the low-frequency connector clamping slot 110 can be used for soldering.

[0049] The unidirectional socket / pin clamping slot 115 can be used for welding CX-1 and CX-2 type unidirectional sockets / pins.

[0050] The clamping slot 111 for the wire handle can be used for welding wire handles with a minimum thickness of 0.6mm.

[0051] The welding bracket fixing device 2 includes a base 201, a base pad 202 fixed on the base 201 by fixing screws 203, a multi-functional clamp that cooperates with the base 201, and several sets of universal arms 206 connected to the multi-functional clamp. The welding bracket fixing device 2 provides two solutions: one for supporting the welding bracket 1 during the repair of off-ground cables, and the other for fixing the welding bracket 1 during the repair of on-board cables.

[0052] like Figure 4 As shown, the welding bracket fixing device 2 is used for ground welding of off-machine cables. At this time, the bubble of the bubble level 108 is in the middle position, and the welding bracket 1 can be welded as long as it is in a vertical state. Welding on the machine for off-machine cables is relatively difficult. Due to the space on the machine and the position of the connector, the welding lacks support points and cannot be fixed with the base 201. However, there are many structural profiles and load-bearing conduits on the machine.

[0053] like Figure 5The image shows the universal arm 206 fixed to the bracket. During welding, a support point can be found on the machine. The universal arm 206 fixed to the bracket is available in three specifications: 150mm, 200mm, and 300mm, with 4 of each type, for a total of 12. They can be freely combined for fixing the welding bracket on the machine. When fixing, make sure that the bubble in the bubble level 108 is in the "weldable zone". The universal arm fixed to the bracket is installed on the universal arm fixing mounting hole 112 of the wire clamping universal arm 104 of the welding bracket 1 using fixing screw 205.

[0054] The multi-functional clamp includes an upper part 207 and a lower part 208 mounted on the end of the universal arm 206. In use, after adjusting the upper part 207 to a suitable position, the multi-functional clamp is secured with the four fastening nuts 209.

[0055] The upper part 207 of the multi-functional clamp can move along the clamping screw 210.

[0056] The universal arm 206 is available in three sizes: 150mm, 200mm, and 300mm. The welding bracket 1 has 12 universal arm mounting holes 112, with 3 holes at each corner, which can be selected as needed during welding.

[0057] The 206 universal arm can be bent arbitrarily according to the actual welding needs on the machine. It is fixed on the machine using a multi-functional clamp, and can be clamped onto structural profiles and supporting conduits.

[0058] The base 201, base pad 202, and soldering iron stand base 301 are all made of pure metal.

[0059] The soldering iron stand 3 includes a soldering iron stand base 301 for increasing stability, a soldering iron placement rack 302 fixed on the soldering iron stand base 301, a timing device 304, and a timing button 305 set on the soldering iron placement rack 302. During the connector soldering process, the soldering iron stand 3 is not limited by the space on the machine, so the soldering iron stand 3 can be used for soldering cables that are on the machine and cables that are off the machine at the same time.

[0060] The timing device 304 is equipped with a setting button 306 for adding or subtracting time, a restart button 303 for restarting the timer when pressed, a time display screen 307 for displaying the remaining countdown time, and a buzzer 308 that sounds an alarm when the maximum time for a single soldering operation is reached. The timing button 305 is used to implement the timing function. When in use, the soldering iron is placed in the soldering iron holder 3, the button is pressed to reset the timer and stop the timer, and the button pops up after the soldering iron is removed, and the timer starts counting again.

[0061] When the reset button 303 is pressed, the timing can be restarted. The timing device 304 is used to measure the time of a single soldering operation to prevent cable damage or degradation of connector electrical performance due to excessive soldering time.

[0062] The time display screen 307 is used to display the remaining countdown time. When the countdown reaches 00:00, it indicates that the maximum time for a single welding operation has been reached. The buzzer 308 emits a "beep" alarm sound to remind the operator that the welding time has been too long. At this time, pressing the reset button 303 will reset the time, stop the alarm sound of the buzzer 308, and restart the timer.

[0063] The method of using this utility model is as follows:

[0064] 1. Connector clamp usage method

[0065] like Figure 7 As shown, first slide the lower connector clamp 103 to the appropriate position as needed, then fix the lower connector clamp 103 with the second fastening nut 114. Then, place the connector to be soldered into the appropriate slot: SMA type RF connectors into RF connector clamping slot 109, low-frequency connectors into low-frequency connector clamping slot 110, and unidirectional sockets / pins into unidirectional sockets / pin clamping slot 115. The wiring handle is as follows... Figure 7 As shown, place the round end into the clamping slot 111 of the connector handle, then adjust the position of 102 on the connector clamp until it can clamp the connector to be soldered, and fix it with the second fastening nut 114.

[0066] 2. How to use the universal arm 104 for clamping wires

[0067] like Figure 7 As shown, first, slide the wire clamping universal arm 104 to a suitable position and then fix it with the fastening nut 106; then, peel off the insulation layer of the wire 116 to be welded according to the process requirements, then place the wire in the wire placement slot 107 of the lower half of the wire clamp 105 and clamp the wire 116; finally, adjust the position of the wire clamping universal arm 104 and the position of the wire placement slot 107 of the wire clamp 105 so that the wire core with the stripped insulation layer is placed in the welding point 117 to be welded.

[0068] 3. How to use the bubble level 108

[0069] like Figure 2As shown, the bubble level 108 is used to control the forward tilt angle of the welding bracket 1 to prevent flux from flowing into the connector during the welding process. When using the fixed base, ensure that the bubble of the bubble level 108 is in the middle position. At this time, the welding bracket 1 is perpendicular to the horizontal plane. When using the bracket to fix the universal arm 206, ensure that the bubble of the bubble level 108 is in the "weldable zone". At this time, the welding bracket 1 is vertical or slightly tilted forward.

[0070] 4. How to use base 201

[0071] like Figure 8 As shown, insert the fixing screw 203 on the base 201 into the base mounting hole 113 on the welding bracket 1, and then tighten it with the fastening nut 204.

[0072] 5. How to use the bracket to fix the universal arm 206

[0073] like Figure 9 As shown, firstly, select a suitable length and number of brackets to fix the universal arm 206 as needed, and install it on the universal arm fixing mounting hole 112 of the welding bracket using fixing screw 205. There are 12 universal arm fixing mounting holes 112 on the welding bracket 1, which can be selected arbitrarily as needed. Then, find a suitable position on the machine, structural profile, load-bearing conduit, loosen the fastening nut 209, and finally fix the welding bracket 1 on the machine using the upper half 207 and the lower half 208 of the multi-functional clamp and the fastening nut 209.

[0074] 6. How to use the timer function

[0075] like Figure 6 As shown, the timing function is implemented through the traditional soldering iron stand 3. The timing device 304 has three setting buttons 306. Pressing the "setting button" of the setting button 306 once allows you to set the countdown in seconds by "adding" or "subtracting". Pressing the "setting button" again allows you to set the countdown in minutes by "adding" or "subtracting". Finally, pressing the "setting button" once completes the setting of the countdown time. When in use, first set the countdown time according to the connector and wire specifications. Place the soldering iron on the soldering iron stand 302. At this time, the timing button 305 is pressed. The time display screen 307 on the timing device 304 displays the maximum countdown time. The buzzer 308 does not sound, and the timer stops counting.

[0076] When soldering begins, the soldering iron is picked up from the soldering iron holder 302, the timer button 305 pops up and the countdown begins. When the countdown reaches 00:00 on the time display screen 307, the buzzer 308 starts to emit a "beep" alarm sound until the reset timer button 303 is pressed to restart the countdown, at which point the buzzer 308 stops sounding.
