Technical Field
[0001] The present invention relates to the field of electronic countermeasure and radar countermeasure cable production, and in particular to a method and device for on-site cable processing. Background Art
[0002] During the production and processing of electronic countermeasures and radar countermeasures products, cables are often required to connect different cabins, such as from the power generation cabin to the antenna vehicle cabin. Since the connection process requires passing through a wall hole, in order to facilitate sealing and reduce electromagnetic leakage, the diameter of the cabin's through-hole is as small as possible. Generally, the aperture of the installation design hole is slightly larger than the diameter of all the cables passing through it. If the cable is processed in advance, the plugs on both sides cannot pass through the aperture. Whether it is maintenance or production and processing, it must be carried out at the production site.
[0003] Currently, electrical workers manually pre-tighten the cable plugs and tail clamps at both ends before moving the cables to a dedicated fixture for tightening. This requires pre-fabrication of the cables and then on-site connection. If the aperture cannot be designed too large, large-scale dedicated fixtures must be brought to the site.
[0004] In this special cable processing field, a miniaturized method or device that is easy to process on site is needed to tighten or disassemble cable plug tail clamps of different specifications and models at the production site or during product after-sales maintenance, meeting the processing needs of portable and small-batch on-site cables.

DETAILED DESCRIPTION
[0033] The technical solution of the present invention is further described below with reference to the accompanying drawings.
[0034] like Figures 1 to 15 As shown, a method for processing cables on site comprises the following steps:
[0035] Step 1: At least one end of the cable is not installed with a plug. The cable without the plug is passed through the required installation hole. Before the two ends of the cable are connected to the electronic device sockets to be installed, on-site processing is performed on the electronic device sockets.
[0036] Step 2: Use a wrench device tool to clamp the toothed portion of the tail clip outer circle 32 of the plug so that the tail clip outer circle 32 cannot move relative to the wrench device.
[0037] Step three: Use a fixing device to insert it from the gap of the plug, and clamp the inner circle raised positioning piece 33 through the fixing device to limit the movement of the inner circle. The present invention can use three or more T-shaped pins to fix the inner circle, so that the inner circle of the plug can be easily fixed during on-site processing.
[0038] Step 4: Separate or tighten the plug and tail clip of the cable by twisting the wrench device and the fixing device, thereby realizing on-site cable processing.
[0039] like Figures 2 to 5 As shown, a device for on-site cable processing includes a fixture 1 and a wrench 2. During operation, the user holds fixture 1 with their left hand and inserts three T-shaped pins 16 into the cable plug slots 31. With their right hand, they hold wrench 2, bringing the serrated surfaces at both ends into contact with the outer diameter 32 of the cable plug's tail clamp. The device is then rotated in different directions to tighten or remove the plug's tail clamp. The device primarily tightens the tail clamp's outer diameter 32.
[0040] like Figure 6 、 Figure 7As shown, the fixing device 1 comprises a housing 11, a guide plate 12, a drive plate 13, a rear cover 14, an adjusting wheel 15, a T-shaped latch 16, and a jackscrew 17. The guide plate 12 is provided with three linear, sequentially arranged holes 121, and the drive plate 13 is provided with a spiral groove 131. Each T-shaped latch 16 is respectively secured to a linear, sequentially arranged hole 121 and a spiral groove 131. As the drive plate 13 rotates, the three T-shaped latches 16, driven by the linear, sequentially arranged holes 121, move synchronously back and forth, thereby securing inner circular protrusions of varying diameters. During the twisting process, the subsequent drive plate 13 does not rotate, creating a self-locking mechanism, allowing it to withstand high torque. The specific operating principle is: rotating the adjusting wheel 15, which, through the rotation of the drive plate 13, drives the T-shaped latches 16 to move radially within the guide plate 12, thereby adjusting the size of the circle formed by the three T-shaped latches 16 to accommodate different cable plugs. Assembly is as follows: Insert the short end of the T-shaped latch 16 into the spiral groove 131 of the drive plate 13. Slide the guide plate 12 over the three T-shaped latches 16, ensuring that the end surfaces of the guide plate 12 and the drive plate 13 are in contact. Place it into the housing 11 as shown. Screw the rear cover 14 to connect it to the housing 11. The D-shaped end of the drive plate 13 passes through the rear cover 14 and is securely connected to the adjustment wheel 15. Screw the jackscrew 17 into the housing 11 to simultaneously secure the housing 11, the guide plate 12, and the rear cover 14. Once completed, adjust the stroke of the T-shaped latch 16 by adjusting the adjustment wheel 15.
[0041] like Figures 8 to 14 As shown, the wrench device 2 primarily comprises an adjusting nut 21, a fixing base 22, an adjusting bolt 23, a U-shaped frame 24, a serrated slider 25, and an extended adjusting rod 26. All components are connected using appropriate threaded connections. The adjusting bolt 23 utilizes a national standard fine thread, which provides a self-locking feature. The B ends of the two adjusting bolts 23 are screwed into the A ends of the two serrated sliders 25, which are then mounted within the two fixing bases 22. The adjusting nut 21 and extended adjusting rod 26 are then attached to the A ends of the adjusting bolts 23. The threads of the two fixing bases 22 are then attached to the ends of the U-shaped frame 24.
[0042] The adjustment principle of the wrench device 2 of the present invention is: by screwing the adjustment nut 21 and extending the adjustment rod 26, the serrated slider 25 slides in the U-shaped frame 24 to adjust the center distance and clamp the outer circle of the tail clamp. The assembly method is as follows: 1. Screw the B ends of the two adjustment bolts 23 into the A ends of the serrated slider 25 (such as Figure 10 2. Place the A end of the two parts assembled in step 1 into the fixing seat 22, so that the threaded end passes through the hole on the end of the fixing seat 22 (as shown). Figure 11 3. Screw the adjusting nut 21 into the threaded end of the component in step 2 (such as Figure 11 ). 4. Screw the threaded end of the assembly in step 3 into the A end of the U-shaped frame 24 (as Figure 12 ). 5. Replace the adjusting nut 21 in step 3 with the extended adjusting rod 26 to complete the installation of the B end of the U-shaped frame 24. 6. Adjust the rotation direction and screw in the top screw to ensure that the guide groove of the serrated slider 25 is aligned with the top screw. After completion, debug the stroke of the serrated slider by adjusting the nut 21 and the extended adjusting rod 26. Finally, through the interaction with the fixing device 1, check whether the device meets the tightening requirements. The extended adjusting rod 26 of the present invention is for easy handholding during operation.
[0043] The T-shaped pin 16 of the present invention can be freely adjusted within a center circle distance of 12mm to 60mm, and the distance between the two serrated sliders 25 in the wrench device 2 can be adjusted between 14mm and 59mm, so as to adapt to the tightening of plugs of different specifications.
[0044] The present invention achieves the following goals: First, during the actual production of finished cables, the tail clamp can be tightened in one go, simplifying the cable production process and improving cable production efficiency. Second, it eliminates geographical constraints during cable production. Third, the flexible and adjustable performance of the fixing device 1 and the wrench device 2 replaces the original tooling and wrenches and tools of different specifications and models, providing increased flexibility and portability, reducing the burden on workers and lowering cable production costs.
