The mounting base 2 is U-shaped, and a sliding groove 4 is formed on the side surface of the mounting base 2. A sliding plate 5 is slidably connected to the inner surface of the sliding groove 4. A mounting hole is formed on the upper surface of the sliding plate 5. A mounting bracket is provided on the upper surface of the mounting base 2 near the mounting hole. Mounting pin 3, a brake plate 6 is fixedly connected to the upper surface of the sliding plate 5 near the center, a guide groove 20 is opened on the upper surface of the base 8 near the protective shell 1, a guide block 12 is slidably connected to the lower surface of the guide groove 20, a second protective shell 7 is fixedly connected to the upper surface of the guide block 12, an insertion plate 13 is fixedly connected to one end of the side surface of the second protective shell 7, an insertion hole is provided on the side surface of the mounting base 2 near the insertion plate 13, there are multiple insertion plates 13, a limit groove 14 is opened on the upper surface of the insertion plate 13, and the inner wall of the second protective shell 7 and the outer wall of the first protective shell 1 are slidably connected. When maintenance of the terminal body 16 is required, simply remove the mounting pin 3, then push the sliding plate 5 to disengage the brake plate 6 from the limit groove 14, release the fixation of the insertion plate 13, then push the second protective shell 7 to disengage the insertion plate 13 from the insertion hole, and the guide block 12 slides in the connecting plate 22, thereby facilitating the opening of the protective area formed by the first protective shell 1 and the second protective shell 7, and making it convenient to maintain the terminal body 16. It improves the ease of maintenance, allowing for easy disassembly without the need for multiple tools.

[0026] A connector 17 is fixedly connected to the upper surface of the limiting groove 14, a connecting plate 22 is fixedly connected to the upper surface of the protective shell 1, a wire 23 is provided in the hole groove of the connector 18 near the insulating sleeve 15, the surface of the wire 23 is attached to the insulating sleeve 15, a terminal body 16 is fixedly connected in the hole groove of the connector 18, and an insulating sleeve 15 is fixedly connected in the hole groove of the connector 18 near the terminal body 16.

[0027] A label box 9 is fixedly connected to the inner wall of the mounting slot 10. A label strip 21 is provided on the upper surface of the label box 9. A through hole is opened on the upper surface of the connecting plate 22 near the connector 17. A mounting slot 10 is opened on the surface of the base 8 away from the connecting plate 22.

[0028] Working principle: One end of the connector 17 passes through a through hole on the surface of the connecting plate 22, allowing connection to external electrical appliances. The insulating sleeve 15 protects the wire 23, preventing mechanical damage to the wire core, avoiding current leakage, and ensuring effective transmission of electrical energy or signals. The terminal body 16 provides further protection for the wire 23, preventing the intrusion of moisture, dust, and other impurities, while optimizing the electric field distribution, reducing the electric field strength, and preventing corona discharge and insulation breakdown. Furthermore, by pulling one end of the second protective shell 7 towards one end of the first protective shell 1, the guide block 12 moves within the guide groove 20, and the inner wall of the second protective shell 7 moves against the outer wall of the first protective shell 1, moving to the mounting base 2 connected to the first protective shell 1. Subsequently, the sliding plate 5 can be pulled up, allowing it to slide above the inner wall of the sliding groove 4. Then, the insertion plate 13 connected to the second protective shell 7 is inserted into the insertion hole on the side surface of the mounting base 2, thus forming a ring-shaped protection for the terminal body 16 in conjunction with the first protective shell 1. Next, the sliding plate 5 can be lowered, allowing the brake plate 6 connected to the sliding plate 5 to be inserted into the limiting groove 14 on the surface of the insert plate 13, thereby restricting the movement of the insert plate 13 and preventing the protective shell 7 from sliding backward under external force. Finally, the sliding plate 5 can be restricted in the sliding groove 4 by using the mounting pin 3 in conjunction with the mounting hole, thereby achieving installation and, in conjunction with the connecting plate 22, protecting the terminal body 16. When maintenance of the terminal body 16 is required, simply remove the mounting pin 3, then push the sliding plate 5 to disengage the brake plate 6 from the limiting groove 14, releasing the fixation on the insert plate 13. Then push the protective shell 7 to disengage the insert plate 13 from the insertion hole, and the guide block 12 slides in the guide groove 20, thereby facilitating the opening of the protective area formed by the protective shell 1 and the protective shell 7, making it convenient to maintain the terminal body 16.
