Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0021] This application discloses a cable branch terminal block, including a clamp 1. A fitting plate 2 is slidably connected to the upper part of the clamp 1. A pressing component 4 is provided at the lower part of the fitting plate 2. The pressing component 4 is used to press the cable. A limiting rod 3 is fixedly connected to the middle part of the pressing component 4. The column of the limiting rod 3 passes through the middle part of the fitting plate 2 and is used to prevent the pressing component 4 from falling off. A baffle 5 is fixedly connected to one end of the clamp 1.

[0022] The wire clamp 1 includes: a U-shaped frame 11 and a sliding groove 12. The upper part of the U-shaped frame 11 is provided with a sliding groove 12, and the sliding groove 12 is slidably connected to the side of the fitting plate 2.

[0023] The fitting plate 2 further includes: threaded hole 21, support block 22, and through hole 23. Support blocks 22 are fixedly connected to the front and rear sides of the fitting plate 2. The support blocks 22 are slidably connected to the inner wall of the slide groove 12. Threaded holes 21 are opened on the left and right sides of the fitting plate 2. The threaded holes 21 are threadedly connected to the upper part of the extrusion assembly 4. Through hole 23 is opened in the middle of the fitting plate 2. The rod of the limiting rod 3 is slidably connected to the inner wall of the through hole 23.

[0024] The extrusion assembly 4 further includes: a lower pressure arc plate 41 and an adjusting bolt 411. The lower part of the extrusion assembly 4 plate is fixedly connected to the upper part of the lower pressure arc plate 41. The left and right sides of the extrusion assembly 4 plate are respectively rotatably connected to the ends of the adjusting bolt 411. The column of the adjusting bolt 411 is rotatably connected to the threaded hole 21.

[0025] Working principle: When connecting cables, the outer sheath of the cable to be connected needs to be stripped, and then inserted into the opening of the U-shaped frame 11. Then, the adjusting bolt 411 is turned. The end of the adjusting bolt 411 is rotatably connected to the plate of the pressing arc plate 41. As the adjusting bolt 411 is turned, it is pressed downward under the constraint of the threaded hole 21. The adjusting bolt 411 drives the pressing arc plate 41 to press the cable placed in the U-shaped frame 11. The side of the pressing arc plate 41 that contacts the cable is arc-shaped, which matches the U-shaped frame 11. The copper core of the cable being pressed is cylindrical. Therefore, the pressing arc plate 41 can tightly press the cable placed in the U-shaped frame 11 during the pressing process. The support block 22 set on the side of the interlocking plate 2 can provide a pressure point when the adjusting bolt 411 drives the pressing arc plate 41 to press down the cable, preventing the pressing arc plate 41 from being damaged due to the applied pressure during the pressing process. Excessive force causes the interlocking plate 2 to detach from the slide groove 12, making it impossible to compress the cable. The support block 22 can also be designed as a double-headed protrusion, and the slide groove 12 is also slotted accordingly. Designing the support block 22 as a double-headed protrusion increases the bearing capacity, thereby enhancing the squeezing force of the lower pressure arc plate 41 on the cable in the U-shaped frame 11. This design can fix cables of thicker specifications. A baffle 5 is set on one side of the U-shaped frame 11, which can quickly position the interlocking plate 2 when it is assembled in the U-shaped frame 11, preventing the interlocking plate 2 from moving out of the U-shaped frame 11. The design of the limiting rod 3 fixedly connecting the compression component 4 and slidingly connecting the through hole 23 can prevent the compression component 4 from detaching from the interlocking plate 2 and prevent it from falling. The wire clamp 1, interlocking plate 2 and lower pressure arc plate 41 are all made of PP environmentally friendly flame-retardant material, which can effectively prevent leakage. The threaded hole 21 is made of copper metal, thereby increasing the current carrying capacity.

[0026] The compression component 4 compresses the cables placed in the U-shaped frame 11. This method makes cable connection convenient; simply tightening the adjusting bolt 411 is sufficient to complete the cable connection. At the same time, the main and branch lines of the cable are directly compressed together, preventing excessive current and overheating during the connection of the main and branch lines. The design of the support block 22 enhances the compressive strength of the compression component 4 on the cable, thereby enabling the compression of cables of different specifications. Furthermore, the U-shaped frame design of the U-shaped frame 11 can accommodate multiple cables for compression and connection.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
