Abstract
Description
Technical Field
[0001] This utility model relates to a special tool, specifically a special tool for soldering DK type bus connectors, belonging to the field of aviation equipment technology. Background Technology
[0002] The tail shielding sleeve of the DK type connector consists of a shielding terminal, a solder ring, and heat shrink tubing. It connects the bus shielding layer to the connector via blow-shrink welding, increasing the anti-interference capability of data transmission. Currently, during cable repair, the lack of specialized tools for blow-shrink welding of the tail shielding sleeve easily leads to loosening and displacement of the shielding terminal, causing the shielding layer to become loose and not fully contact the connector, affecting service life and reducing anti-interference capability. Some operators use needle-nose pliers to fix the tail shielding sleeve, which can cause the shielding terminal to become misaligned or the processed parts to slip during blow-shrink welding, resulting in poor welding quality and potential damage to the connector. The tail shielding sleeve welding of this type of connector requires a single blow-shrink forming process; if improper installation occurs, it is difficult to remedy later, resulting in waste and rework. Therefore, this application designs a small, simple-to-use specialized tool for welding DK type bus connectors, which can greatly improve the welding quality of this type of bus connector and reduce economic losses.

[0019] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0020] Please see Figure 1-4As shown, a special tool for soldering DK type bus connectors includes a stabilizing base 1. Both ends of the top of the stabilizing base 1 are connected to connector bases 2 for fixing connectors 8. A slide rod 5 is also vertically connected to one side of the top of the stabilizing base 1. A limit clamp 3 is slidably fitted on the outside of the slide rod 5.
[0021] Specifically, one end of the limiting clamp 3 has a through hole extending from top to bottom, and a positioning screw 4 is threadedly connected to the side of one end of the limiting clamp 3. One end of the positioning screw 4 can extend into the interior of the through hole. The limiting clamp 3 is fitted onto the outside of the slide rod 5 through the through hole and slides up and down on the outside of the slide rod 5 through the through hole. The other end of the limiting clamp 3 is connected to a horizontal plate 6. A limiting groove 7 is formed at the end of the horizontal plate 6 away from the limiting clamp 3, and the end of the limiting groove 7 away from the limiting clamp 3 is open.
[0022] The top of the slide rod 5 passes through the through hole in the limiting clamp 3, allowing the limiting clamp 3 to be fitted onto the outside. When the limiting clamp 3 needs to be adjusted vertically, it can be pushed and slid up and down outside the slide rod 5. When the limiting clamp 3 needs to be rotated, it can be pushed through the through hole to rotate outside the slide rod 5. When the limiting clamp 3 needs to be fixed outside the slide rod 5, the positioning screw 4 is tightened. One end of the positioning screw 4 extends into the through hole and abuts against the outer wall of the slide rod 5, thus limiting the limiting clamp 3 and maintaining the required height and angle outside the slide rod 5.
[0023] Specifically, the top of the connector base 2 is provided with a mounting hole for mounting the connector 8, and the inner wall of the mounting hole is provided with a plurality of vertically arranged limiting grooves 9 from top to bottom. Below each limiting groove 9, the inner wall of the mounting hole is integrally provided with a guide groove 10, which is arc-shaped and penetrates the side wall of the mounting hole.
[0024] The connector 8 has a plug post 12 connected to its bottom, and multiple positioning teeth 11 are connected to the outer wall of the plug post 12. When installing the connector 8 with the connector base 2, the bottom end of the plug post 12 is inserted into the mounting hole. The positioning teeth 11 correspond to the positions of the limiting grooves 9. During insertion, the positioning teeth 11 enter the interior of the limiting grooves 9 and slide downwards along the limiting grooves 9. As insertion deepens, the positioning teeth 11 enter the interior of the guide groove 10 along the limiting grooves 9. At this time, by rotating the connector 8, the positioning teeth 11 can slide downwards into the interior of the guide groove 10 until they slide to the lowest end of the guide groove 10. The lowest end of the guide groove 10 is rounded to facilitate the locking and fixing of the positioning teeth 11. At this time, the connector 8 is stably installed above the connector base 2. If it is necessary to disassemble the connector 8, the above steps are reversed. First, the connector 8 is rotated in the opposite direction, and then the connector 8 is pulled upwards to remove it from the top of the connector base 2.
[0025] When wire 13 and connector 8 need to be soldered together, the bottom end of connector 8 is mounted above connector base 2. Then, the insulation layer on a section of the outer wall of the bottom end of wire 13 is stripped to expose the inner shielding layer. A connector tube 15 is integrally connected to the top end of connector 8. The wire core inside the bottom end of wire 13 is inserted into the inside of connector tube 15, and the shielding layer is fitted over the outside of connector tube 15. Then, the tail-attached shielding sleeve 14 for soldering is fitted over the outside of the shielding layer. When fitting the tail-attached shielding sleeve 14, the top of wire 13 passes through the inside of the tail-attached shielding sleeve 14, and the tail-attached shielding sleeve 14 is moved downwards to fit over the outside of the shielding layer. The tail-attached shielding sleeve 14 is used to solder and secure the connection between the shielding layer and connector tube 15, providing protection.
[0026] A limiting plate is connected to the upper end of connector 8 below connector tube 15. After the tail shielding sleeve 14 and shielding layer are fitted together, the bottom end can be restricted by the limiting plate, making it easier to control the fitting position during fitting. After the tail shielding sleeve 14 is fitted, adjust the height and angle of the limiting clamp 3 outside the slide rod 5 so that the bottom of the limiting clamp 3 contacts the top of the tail shielding sleeve 14, pressing and limiting the tail shielding sleeve 14. The wire 13 is then engaged inside the limiting groove 7. This ensures that the wire 13 is perpendicular or nearly perpendicular to connector 8. Then, tighten the positioning screw 4 to keep the limiting clamp 3 fixed outside the slide rod 5.
[0027] Subsequently, a hot air gun is used to heat and shrink the tail-attached shielding sleeve 14, causing the internal solder rings to melt evenly at the corresponding positions. After the solder rings melt, they weld the shielding layer, shielding terminal, and connector tube 15 above the connector 8 together, thus connecting the shielding layer, shielding terminal, and connector 8 into a single unit. The welding is then complete, and the connector 8 is detached from the connector base 2. This specialized tool provides stable positioning for the connector 8, tail-attached shielding sleeve 14, and wire 13, resulting in more precise welding and reducing the likelihood of instability or insufficient welding due to tilting.
[0028] Both connector 8 and tail shielding sleeve 14 are existing technologies, and this application does not improve upon these two components. The tail shielding sleeve 14 includes a shielding terminal, a solder ring, and heat shrink tubing. The solder ring is fitted over the shielding terminal, and the heat shrink tubing is fitted over the solder ring. In use, the shielding terminal is fitted over the shielding layer. Furthermore, when soldering different models of connector 8, different connector bases 2 above the stabilizing base 1 can be selected according to their specific models. The two connector bases 2 above the stabilizing base 1 are two different models. The number of limiting slots 9 inside the connector bases 2 varies depending on the model. For example, the connector base 2 for ABC key positions has three limiting slots 9, while the connector base 2 for D-type key positions has four limiting slots 9.
[0029] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
