[0040] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0041] like Figure 1-5 As shown, a conductor protection device for preventing short circuits in electrical connections is used for installation on a rail inside a distribution box, comprising:

[0042] The track mounting base 1 has a slot that matches the rail inside the distribution box, and the track mounting base 1 has a magnetically attached base 2 inside.

[0043] Magnetic base 3 is magnetically connected to magnetically attracted base 2;

[0044] The housing 5 is fixed on the magnetic base 3. Multiple wire insertion holes 507 are arranged horizontally on the housing 5. The housing 5 is also provided with multiple clamping holes 508 corresponding to the wire insertion holes 507. The clamping holes 508 are connected to the wire insertion holes 507. The housing 5 is provided with a lower fixing groove.

[0045] A clamping rod assembly is movably disposed within a clamping hole 508, and one end of the clamping rod assembly is adapted to extend into a wire insertion hole 507;

[0046] The clamping arm 505 is hinged to the housing 5 in the middle. One end of the clamping arm 505 is hinged to the other end of the clamping rod assembly. The lower surface of the other end of the clamping arm 505 is provided with an upper fixing groove.

[0047] The elastic reset element 511 has its two ends fixed in the upper fixing groove and the lower fixing groove, respectively.

[0048] In this embodiment, as Figure 1-5 As shown, during actual maintenance of electrical equipment, workers can install the track mounting base 1 on the rail inside the distribution box, or directly attach the housing 5 to the inner wall of the distribution box via the magnetic base 3. Multiple horizontally arranged wire insertion holes 507 on the housing 5 facilitate the insertion of wires of various specifications. By pressing the clamping arm 505, the clamping arm 505 rotates via a hinge, causing the clamping rod 504 to move within the clamping hole 508, allowing the wire to be easily inserted into the wire insertion hole 507. After releasing the clamping arm 505, the spring force pushes the clamping rod 504 to clamp the wire, achieving rapid installation and fixation of the wire. This improves the convenience and safety of maintenance personnel, effectively avoiding the risk of short circuits or grounding caused by exposed wires.

[0049] The housing 5 can specifically be a housing 501. The elastic reset element 511 can specifically be a spring. The upper end of the spring is provided with an upper mounting base 512 for fixing, and the lower end is provided with a lower mounting base 513 for fixing.

[0050] Specifically, such as Figure 1-3 As shown, the conductor protection device for preventing short circuits in electrical connections also includes a magnetic mounting assembly, which includes:

[0051] Magnetic base 2 is fixed on track mounting base 1;

[0052] Magnetic base 3 is magnetically connected to magnetically attracted base 2;

[0053] The housing 5 is mounted on the magnetic base 3.

[0054] In this embodiment, as Figure 1-3 As shown, the magnetic base 2 is equipped with an insulating sleeve 4. Inside the magnetic base 2 is a rotatable permanent magnet with N and S poles at both ends. The outer shell of the magnetic seat 3 is constructed from two magnetically conductive pieces separated by a non-magnetic material. The magnetic seat 3 and the magnetic base 2 are magnetically connected, and the shell 5 is fixedly mounted on the outer surface of the magnetic seat 3. The magnetic seat 3 is mainly composed of soft magnetic material. When the poles of the permanent magnet face the soft magnetic material, the soft magnetic material is magnetized and exhibits a strong magnetism in that direction, thus enabling it to attract the magnetic base.

[0055] Specifically, such as Figure 1-5 As shown, the housing 5 is also provided with an electrical detection hole 516 that is connected to the wire insertion hole 507;

[0056] The conductor protection device for preventing short circuits in electrical connections also includes an electrical detection component, which includes:

[0057] The first metal contact conductive sheet 510 is fixedly disposed inside the electrical detection hole 516;

[0058] The second metal contact conductive sheet 514 is disposed inside the wire insertion hole 507;

[0059] Connecting wire 515, with its two ends electrically connected to the first metal contact conductive piece 510 and the second metal contact conductive piece 514, respectively.

[0060] In this embodiment, as Figure 4-5 As shown, the first metal contact conductive piece 510 and the second metal contact conductive piece 514 in the electrical detection assembly can both be made of copper alloy material with good conductivity, and are connected by connecting wires 515 to form a circuit. The second metal contact conductive piece 514 is fixed to the inner bottom wall of the wire insertion hole 507. When a live wire is inserted into the wire insertion hole 507, the metal end of the live wire is in close contact with the second metal contact conductive piece 514. The electrical detection hole 516 is designed to match the specifications and dimensions of a multimeter probe. Maintenance personnel can insert the multimeter probe into the electrical detection hole 516 to contact the first metal contact conductive piece 510, and determine whether the live wire is energized by measuring the voltage value. Each wire insertion hole 507 is provided with a corresponding electrical detection hole 516 to ensure that maintenance personnel can test the energization status of each live wire separately.

[0061] In practical applications, the electrical detection components provide maintenance personnel with a convenient way to monitor circuit status. After the live wires are installed, maintenance personnel can perform electrical tests without touching them. The test results can promptly identify circuit faults or confirm whether the maintenance area is de-energized, thus improving the safety and reliability of maintenance operations.

[0062] Specifically, such as Figure 4-5 As shown, the clamping rod assembly includes:

[0063] The clamping rod 504 is hinged at one end to the clamping swing arm 505.

[0064] A clamping block 509 is installed on the other end of the clamping rod 504. The clamping block 509 is provided with an arc-shaped wire groove that matches the outer diameter of the wire.

[0065] In this embodiment, as Figure 4-5 As shown, the clamping rod 504 can be made of plastic, which has good insulation properties and mechanical strength. The bottom of the clamping block 509 is designed with an arc-shaped wire groove, the inner diameter of which matches the outer diameter of the power cord, enabling effective clamping of power cords of different models.

[0066] The clamping block 509 can move up and down within the clamping hole 508 under the action of the clamping rod 504. When the clamping arm 505 presses down, the clamping rod 504 drives the clamping block 509 to move upward, providing space for the insertion of the power cord. When the clamping arm 505 is released, the clamping block 509 moves downward under the action of the elastic reset element 511, and the arc-shaped wire groove fits tightly with the power cord, firmly fixing the power cord in the wire insertion hole 507.

[0067] A raised support platform 506 is formed on the housing 5 at the hinge point with the clamping swing arm 505. The support platform 506 is provided with a mounting groove and a rotating shaft for hinge connection.

[0068] Specifically, such as Figure 1-5 As shown, the wire protection device for preventing short circuits in electrical connections also includes an insulating grid assembly 502, which has multiple wire mounting slots corresponding to the wire insertion holes 507 of the housing 5.

[0069] In this embodiment, as Figure 4-5 As shown, the opening width of each wire mounting slot is slightly larger than the diameter of the wire insertion hole 507, which facilitates the insertion and fixing of the power cord.

[0070] The insulating grille assembly 502 is provided with five wire mounting slots, forming physical isolation between power lines and preventing short circuits. During device use, the insulating grille assembly 502 serves to separate and guide the power lines. When maintenance personnel need to secure multiple power lines simultaneously, the insulating grille assembly 502 ensures that each power line enters its corresponding wire insertion hole 507 along a predetermined path.

[0071] Specifically, such as Figure 4-5 As shown, the wire protection device for preventing short circuits in electrical connections also includes an identification plate 503, which is fixedly mounted on the upper surface of the clamping swing arm 505.

[0072] The label plate 503 corresponds one-to-one with the clamping swing arm 505.

[0073] In this embodiment, as Figure 4-5 As shown, the label plate 503 is embedded in the upper surface of the clamping arm 505. The five label plates 503 correspond to the five clamping arms 505 respectively. Each label plate 503 has a clear combination of numbers and letters to record the power cord serial number and usage information corresponding to the wire insertion hole 507.

[0074] The upper surface of the label plate 503 is designed with an anti-slip texture to provide good tactile feedback for maintenance personnel when operating the clamping swing arm 505.

[0075] The design of the label 503 enables maintenance personnel to accurately identify the location and function of each power cord. During electrical equipment maintenance, personnel can quickly confirm the installation sequence of the power cords based on the information on the label 503, avoiding equipment damage caused by incorrect power cord connections. When it is necessary to replace or maintain electrical components, the information provided by the label 503 helps maintenance personnel accurately restore circuit connections.

[0076] Specifically, such as Figure 1-3 As shown, the casing 5 is made of insulating material.

[0077] Specifically, such as Figure 1-5 As shown, there are five clamping arms 505, which are arranged at equal intervals along the transverse direction on the housing 5.

[0078] In this embodiment, as Figure 1-5As shown, during the maintenance of electrical equipment, when operators need to disassemble electrical components, depending on the maintenance location, the operators can install the track mounting base 1 on the corresponding rail in the distribution box, and then attach the housing 5 to the magnetic base 2 via the magnetic seat 3. Alternatively, the housing 5 can be directly attached to the inner wall of the distribution box via the magnetic seat 3. The power cord connecting the electrical components is then disconnected, and the disconnected power cord is installed in the corresponding wire insertion hole 507 according to the markings on the label plate 503. During installation, the swing arm 505 is pressed down at the corresponding point by the fingers, at which time the elastic reset element 511 is compressed and tightened. Rod 504 moves clamping block 509 upward, inserting the power cord into wire insertion hole 507. The head of the power cord contacts the second metal contact conductive piece 514. At this time, the finger releases the clamping arm 505, and the reaction force of elastic reset element 511 causes clamping block 509 to press the power cord. The second metal contact conductive piece 514 is connected to the first metal contact conductive piece 510 through connecting wire 515. Once the power cord is energized, the voltage of the first metal contact conductive piece 510 can be measured by a multimeter. In this way, the housing 5 can fix five power cords at the same time, which is convenient for operators to replace electrical components.

[0079] The specific embodiments described above further illustrate the technical problems, technical solutions, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
