Detailed Implementation Methods

[0028] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] Specific embodiments, combined with Figures 1 to 7 As shown, the technical solution of this utility model is further explained. A port-fastening anti-detachment drive power supply box includes a power supply box base 1 and a cover plate 2 that cooperates with it to form a space for installing electrical components and wiring. The power supply box base 1 includes a side plate 11 that cooperates with the cover plate 2 and a first baffle 12 for protecting the internal wiring. The cover plate 2, the side plate 11, and the first baffle 12 form a space for installing components and accommodating wiring. The power supply box base 1 has terminal blocks 3 on both sides for connecting external wires. The terminal blocks 3 include a wiring mechanism 31 for fastening the wires and a mounting mechanism 32 for mounting the wiring mechanism 31. The wiring mechanism 31 includes a contact piece 311 and a mounting member 312 that cooperates with the contact piece 311 to fasten the wires. One side of the mounting member 312 is connected to a fastener 313 for driving it to rise and fall to cooperate with the contact piece 311 to press or loosen the wire inserted therein. The mounting mechanism 32 is provided with a limiting part 321 for preventing the fastener 313 from falling off when adjusting the rise and fall of the mounting member 312. The fastener 313 can drive the mounting part 312 to move and adjust. During this process, the fastener 313 can drive the mounting part 312 to rise and fall, so that the mounting part 312 cooperates with the contact piece 311, so that the inserted wire is pressed or released. The contact piece 311 is conductive. When the wire is pressed, it ensures that the wire and the contact piece 311 maintain electrical connection. When the wire is released, it is easy to remove the wire to correct the wire connection. At the same time, during this adjustment process, the limiting part 321 of the mounting mechanism 32 can restrict the movement of the fastener 313 to prevent it from falling out of the power box and affecting subsequent adjustment work, and provide convenience for wiring the drive power box.

[0030] In this embodiment, the mounting mechanism 32 is provided with a movable part 322 for the mounting member 312 to move up and down. The fastener 313 includes a mating part 3131 for driving the mounting member 312 to move up and down and a linkage part 3132 for driving the mating part 3131 to work. The linkage part 3132 is located within the limiting part 321. The movable part 322 is a cavity corresponding to the mounting member 312, which can ensure that the mounting member 312 moves up or down under the action of the fastener 313, thereby cooperating with the contact piece 311 to clamp or loosen the wire.

[0031] Furthermore, the limiting part 321 has a first step 3211 on the side away from the mounting member 312 to limit the range of motion of the linkage part 3132, and a second step 3212 on the side of the limiting part 321 closer to the mounting member 312 to limit the range of motion of the linkage part 3132. The minimum inner diameter of the first step 3211 is smaller than the outer diameter of the linkage part 3132, and the minimum outer diameter of the second step 3212 is smaller than the outer diameter of the linkage part 3132 but larger than the outer diameter of the mating part 3131. The first step 3211 can be later set at the limiting part 321 to limit the fastener 313, ensuring that the fastener 313 is always within the mounting mechanism 32 during operation, preventing it from falling out of the drive power box, thereby avoiding circuit failure due to failure to tighten the wires, and avoiding the problem of having to find and reset the fastener 313 for subsequent adjustments, thus providing convenience for wiring the drive power box.

[0032] Furthermore, the contact piece 311 includes a current-conducting portion 3111 for conducting current and a clamping portion 3112 for engaging with the mounting member 312 to secure the wiring. The mounting mechanism 32 has multiple wiring ports 323 for wire connection. The mounting member 312 has a central cavity corresponding to the wiring port 323, and the clamping portion 3112 is disposed within the central cavity of the mounting member 312. The contact piece 311 clamps or releases the wire by engaging with the central cavity of the mounting member 312 through the clamping portion 3112.

[0033] During this process, when the fastener 313 moves the mounting member 312 upward, the mounting member 312 moves upward relative to the contact piece 311 until the pressing part 3112 of the contact piece 311 approaches or contacts the through cavity side of the mounting member 312, thereby pressing the wire; when the fastener 313 moves the mounting member 312 downward, the mounting member 312 moves downward relative to the contact piece 311, thereby loosening the wire.

[0034] Furthermore, the fastener 313 is a structure that mates with the mounting member 312. As a preferred embodiment of this solution and not a limitation, the fastener 313 is a screw that mates with the mounting member 312, wherein the screw head corresponds to the linkage part 3132 and the screw shank corresponds to the mating part 3131. The mounting member 312 is provided with a structure that mates with the fastener 313. By mates the fastener 313 with the mounting member 312, the contact piece 311 is used to clamp or loosen the wire.

[0035] Furthermore, the mounting mechanism 32 is provided with a wiring section for cooperating with the contact piece 311 to connect external wires to components within the space formed by the cover plate 2, the side plate 11, and the first baffle 12. A protective member 33 is movably provided on the side of the mounting mechanism 32 near the limiting part 321 to prevent the fastener 313 from falling off. The wiring section can be electrically connected to the contact piece 311, transmitting current to the internal components for processing when the contact piece 311 contacts the power line, and then delivering the processed current to the wiring port 323 of the mounting mechanism 32 on the other side. The protective member 33 can cover the mounting mechanism 32. When the protective member 33 is removed, the wires can be adjusted by the fastener 313 to tighten or loosen. When the protective member 33 is installed, it prevents the fastener 313 from falling out of the drive power box, further improving the management of the fastener 313.

[0036] Furthermore, as a preferred embodiment of this solution and not a limitation, the protective component 33 is a transparent structure that facilitates observation of its interior.

[0037] In this embodiment, the side plate 11 is provided with a groove 111 for sliding with the cover plate 2, and the cover plate 2 is provided with a protrusion 21 that mates with the groove 111. The cooperation between the groove 111 and the protrusion 21 facilitates the installation and adjustment of the cover plate 2.

[0038] Furthermore, the cover plate 2 is provided with a second baffle 22 near the terminal block 3 to limit its sliding range. As an embodiment of this solution and not a limitation, the second baffle 22 extends a certain distance toward the power box base 1. Taking the position of the power box base 1 as the horizontal plane, the height of the side of the second baffle 22 near the power box base 1 is lower than the height of the side of the protective member 33 away from the power box base 1, which can limit the cover plate 2.

[0039] Furthermore, the cover plate 2 is provided with multiple holes for heat dissipation, which can ensure heat dissipation while protecting the internal components.

[0040] The working principle of this embodiment is as follows:

[0041] This utility model proposes a port-fastening anti-detachment drive power supply box, which uses the limiting part 321 of the mounting mechanism 32 to limit the fastener 313, preventing the fastener 313 from falling off during the process of adjusting the mounting part 312 in conjunction with the contact piece 311 to press or loosen the wire. Its specific working principle is as follows:

[0042] When the fastener 313 moves the mounting part 312 upward, the mounting part 312 moves upward relative to the contact piece 311 until the pressing part 3112 of the contact piece 311 approaches or contacts the through cavity side of the mounting part 312, which is used to press the wire; when the fastener 313 moves the mounting part 312 downward, the mounting part 312 moves downward relative to the contact piece 311, which is used to loosen the wire.

[0043] In this process, the first step 3211 can prevent the fastener 313 from falling out of the drive power box, and the second step 3212 can ensure that the fastener 313 works within the limiting part 321, while preventing the fastener 313 from entering the movable part 322 and affecting the use of the drive power box.
