[0002] High-speed connectors are connections that can maintain stable transmission performance under high-frequency signals. Compared with traditional connectors, high-speed connectors need to consider key factors such as signal integrity, electromagnetic compatibility and transmission delay in their design. They are widely used in the field of high-speed data transmission, and the practical wire harnesses that come with them are one of the necessities for connecting multiple electronic devices.

[0003] Depending on the requirements, the wire harness of high-speed connectors will be bent at different angles. This results in different lengths of wires during the production and soldering process.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0025] Reference Figures 1-4 A semi-automatic wire pressing mechanism, compatible with existing wire cutting mechanisms, includes a mounting frame 3 and a base plate 11. The mounting frame 3 comprises two parts: a first mounting frame and a second mounting frame. A wire assembly for placing wires is mounted on the base plate 11. A wire pressing check block 14 for pressing the wires is installed within the mounting frame 3 via a telescopic assembly. The wire assembly includes two placement plates 9 fixedly connected to the base plate 11, designated as a first plate and a second plate, respectively, and located within the first and second mounting frames. Each placement plate 9 is equipped with a wire pressing plate 15, on which the wires are placed. Two wire pressing plates 15 are also included: a first pressing plate and a second pressing plate. A through groove is provided in the center of the first pressing plate located below the telescopic assembly. Figure 3 As shown, the telescopic assembly includes a telescopic cylinder 2 mounted on a mounting frame 3. The telescopic cylinder 2 is mounted on the first mounting frame, and a right-angle block 10 is mounted on the output end of the telescopic cylinder 2. The right-angle block 10 is fixedly connected to the wire pressure check block 14 through a connecting block. A track 13 is mounted on the inner side wall of the mounting frame 3, and a track plate is slidably connected to the track 13. The track plate is fixedly connected to one side of the wire pressure check block 14. When the telescopic cylinder 2 is activated, its output end drives the right-angle block 10 to move downward, and the right-angle block 10 drives the wire pressure check block 14 to move downward through the connecting block. Under the limit of the track plate, the downward movement of the wire pressure check block 14 is more stable. Slowly, the wire pressure check block 14 will pass through the first pressure plate and press on the wire, keeping it stable and preventing the wire from bending and moving when it is cut.

[0026] refer to Figures 1-2The mounting frame 3 also houses a lifting plate 20 via a lifting assembly. The lifting assembly includes a servo motor 1 mounted on the mounting frame 3, which is mounted on a second mounting frame. The output end of the servo motor 1 is connected to a ball screw 17 via a coupling 4. The connections between the coupling 4 and the servo motor 1, and between the coupling 4 and the ball screw 17, are existing technologies, and their working principles are not described in detail. The lifting plate 20 is mounted on the ball screw 17 and can move up and down. A matching ball bolt sleeve is mounted on the ball screw 17. The lifting plate 20 is mounted on the ball bolt sleeve. Rotation of the ball screw 17 causes the ball bolt sleeve to move up and down, thereby moving the lifting plate 20 up and down. The connection between the ball bolt sleeve and the ball screw 17 is existing technology, and its working principle is not described in detail. Two rows of limiting shafts 16 are symmetrically arranged on the lifting plate 20. Each row of limiting shafts 16 is fixedly installed on the lifting plate 20 to ensure that the movement of the two is consistent. Each limiting shaft 16 is equipped with a limiting nut that abuts against the upper side wall of the lifting plate 20. A pressure plate 6 is fixedly connected to the bottom end of each limiting shaft 16. A tension spring 5 is installed on each pressure plate 6. The tension spring 5 is located on one side of the limiting shaft 16 and is arranged parallel to the limiting shaft 16. A threaded pin 19 is installed at the end of the tension spring 5 away from the pressure plate 6 and is threadedly connected to the second mounting bracket. A concave linear speed guide plate 8 of the second pressure plate is installed at the lower end of the pressure plate 6. A fixing plate 7 is embedded in the second mounting bracket. One end of the pressure plate 6 passes through the fixing plate 7 and is connected to the linear speed guide plate 8. Multiple linear speed guide plates are provided on the second pressure plate. The matching groove 8, the linear speed guide plate 8, performs wire pressing through the groove. First, the threaded pin 19 is adjusted according to the length of the wire to be cut by the cutting mechanism. Here, we first introduce the material pressing process. The servo motor 1 starts and drives the ball screw 17 to rotate, thereby causing the lifting plate 20 to move downward. The lifting plate 20 will drive the limit shaft 16 to move downward, thereby causing the wire pressing plate 6 connected to it to drive the linear speed guide plate 8 to move downward, thus pressing the wire tightly. Then, the subsequent cutting mechanism performs cutting. After the cutting is completed, the lifting plate 20 moves upward with the ball screw 17. Under the rebound of the tension spring 5, it drives the wire pressing plate 6 to move upward and reset, thereby allowing the linear speed guide plate 8 to reset and detach from the wire. Since the downward distance of the wire pressing plate 6 is the same, the initial height of the wire pressing plate 6 is... The height of the threaded pin 19 determines whether the wire clamping plate 8 can perform wire clamping. Here, the height of the threaded pin 19 is adjusted according to the cutting requirements; that is, rotating the threaded pin 19 changes its height, thereby changing the height of the corresponding clamping plate 6 and the thread speed guide plate 8. When the thread speed guide plate 8 moves downwards, some wire is clamped by the thread speed guide plate 8, while some wire is not. During cutting, only the clamped wire is cut. Thus, the length of the unclamped wire after being fed backwards is longer than the length cut in the first cut. In this way, different wire length requirements can be met. By adjusting the height of the threaded pin 19, the length of different wires can be adjusted. This process can be repeated to cut according to different wire length requirements.This avoids wasting cable.

[0027] Multiple clips are installed at equal intervals on the side wall of the mounting frame 3. A right-angle plate 21 is installed between two adjacent clips. The right-angle plate 21 extends into the mounting frame 3 and is located above the lifting plate 20. Its purpose is to limit the position of the lifting plate 20 and ensure that the initial position of the lifting plate 20 is controllable and the same each time. This prevents the lifting plate 20 from rising too high when resetting, which would result in insufficient travel when moving downwards and causing the cut material to be unqualified.

[0028] A guide shaft 18 is fixedly installed on the inner wall of the mounting bracket 3. The guide shaft 18 passes through the lifting plate 20, and the lifting plate 20 moves up and down on the guide shaft 18. The guide shaft 18 plays a guiding role, so that the lifting plate 20 can be accurately installed in the corresponding position when it is installed.

[0029] A buffer pad 12 is fixedly connected to the fixed plate 7. A ball screw 17 passes through the center of the buffer pad 12. The buffer pad 12 does not rotate with the rotation of the ball screw 17. Firstly, when the equipment is running, the buffer pad 12 plays a buffering role, and at the same time, it avoids overload of the ball screw sleeve.

[0030] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
