[0026] Example

[0027] like Figure 1-4 As shown, this utility model provides a technical solution: a novel flexible DC capacitor lead-out assembly, including a housing 1. The housing 1 not only provides support but also ensures that its internal components are in a fixed environment during operation, preventing loosening or damage caused by external factors. A support plate 2 is fixedly installed inside the housing 1 to support and fix the assembly. A fixing assembly is provided on the top of the support plate 2. An adjustment groove is provided on one side of the housing 1. A second guide rod 14 is slidably connected inside the adjustment groove. Multiple second guide rollers 15 are rotatably connected to the outer periphery of the second guide rod 14 through bearings. A stop rod 16 is rotatably connected to one side of the housing 1. The design of the pin hole and pin 17 allows the second guide rod 14 to be fixed in a suitable position when guiding different types of wires. Pin holes are provided on both sides of the adjustment groove. A pin hole is provided at one end of the stop rod 16. A pin 17 is provided inside the pin hole to lock the second guide rod 14 and prevent accidental movement. The pin 17 passes through the stop rod 16 and is movably connected inside the pin hole.

[0028] Connecting seats 9 are fixedly installed on both sides of the housing 1. The connecting seats 9 have threaded holes inside. A connecting collar 10 is fitted around the outer periphery of the connecting seats 9 to connect the screw 11 to the housing 1. The connection between the two housings 1 is stable through the threaded connection. The connecting collar 10 has a screw 11 inside. The screw 11 passes through the connecting collar 10 and is threaded into the threaded hole.

[0029] The fixing assembly includes a knob 3, a rotating shaft 4, and bidirectional screws 5. The top of the support plate 2 is rotatably connected to the rotating shaft 4. Multiple bidirectional screws 5 are coaxially fixedly connected to the outer circumference of the rotating shaft 4. A knob 3 is coaxially fixedly connected to one end of the rotating shaft 4. The user operates the rotating shaft 4 by rotating the knob 3. The rotation of the rotating shaft 4 will drive the multiple bidirectional screws 5 connected to it to move, thereby adjusting the nuts 6 threaded to both ends to move in opposite directions, thereby driving the fixing block 8 to fix the wires entering the device. The rotation of the knob 3 will drive the rotating shaft 4 to rotate. The fixing assembly also includes nuts 6, fixing rods 7, and fixing blocks 8. Nuts 6 are threaded to both ends of the bidirectional screws 5. Fixing rods 7 are fixedly installed on the top of the nuts 6. Fixing blocks 8 are fixedly installed on the corresponding side of the two fixing rods 7. The corresponding side of the two fixing blocks 8 is an arc-shaped surface, and the two fixing blocks 8 cooperate with each other.

[0030] A first guide rod 12 is fixedly installed inside a housing 1. Multiple first guide rollers 13 are rotatably connected to the outer periphery of the first guide rod 12 via bearings. The outer periphery of the first guide rollers 13 and the second guide rollers 15 are both designed with concave groove structures. The first guide rollers 13 and the second guide rollers 15 cooperate with each other. The concave groove structures between the first guide rollers 13 and the second guide rollers 15 cooperate with each other to ensure that they always remain aligned during sliding, reduce friction and errors, and ensure accurate guidance of the wire. A sealing layer 18 is fixedly installed inside both housings 1. A waterproof layer 19 is fixedly installed on the side of the sealing layer 18 away from the housing 1. The sealing layer 18 and the waterproof layer 19 ensure the safety of the device, prevent external moisture or other substances from entering, and protect the internal structure from damage. Multiple slots are opened on the corresponding side of the two housings 1, and the slots are matched in pairs.

[0031] The working process of this utility model:

[0032] Step 1: Operate the rotating shaft 4 by rotating the knob 3. The rotating shaft 4 drives the bidirectional screw 5 to move, which in turn moves the adjusting nut 6 in opposite directions. At this time, the fixing rod 7 begins to push the fixing block 8 to fix the wire. Through this action, the arc-shaped surface of the fixing block 8 makes close contact with the wire, ensuring that the wire is firmly in place in the device.

[0033] Step 2: The first guide rod 12 and the second guide rod 14 inside the housing 1, together with the first guide roller 13 and the second guide roller 15, ensure that the wire is guided along the predetermined path. The concave groove structure ensures that the wire remains aligned during the guiding process, reduces friction, and ensures that the wire passes smoothly.

[0034] Step 3: By adjusting the stop lever 16 and the pin 17, the pin 17 fixes the stop lever 16 in a suitable position. At this time, the position of the wire is locked, avoiding unnecessary movement. If different types of wires need to be processed for exiting, only the stop lever 16 and the pin 17 need to be adjusted. In addition, the sealing layer 18 and the waterproof layer 19 provide effective protection to ensure the safety of the equipment in different working environments.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
