[0029] Multifunctional distribution cabinet terminal structure, such as Figure 1-Figure 3As shown, it includes a terminal block 10 with an L-shaped cross-section for installation in a distribution cabinet, and a two-level stepped incoming line bar 20 and an outgoing line bar 30 are installed on the terminal block 10, and a number of evenly and equidistantly arranged locking bolts 50 are installed on the incoming line bar 20 and the outgoing line bar 30; a number of evenly and equidistantly arranged incoming sockets 22 that cooperate with the locking bolts 50 are opened on the top of the incoming line bar 20, and a number of evenly and equidistantly arranged outgoing sockets 32 that cooperate with the locking bolts 50 are opened on the bottom of the outgoing line bar 30; the number of incoming sockets 22 on the incoming line bar 20 and the number of outgoing sockets 32 on the outgoing line bar 30 are the same and their positions correspond to each other. Each incoming jack 22 and outgoing jack 32 is equipped with a replaceable wire fixing head 40. The wire fixing head 40 is adapted to the size of the incoming jack 22 and the outgoing jack 32 and is plugged in with interference fit. The end of the wire fixing head 40 is coaxially provided with a limit cap 41. The incoming wire row 20 and the outgoing wire row 30 are provided with a two-level stepped shape, so that the line connection is clearer and more orderly, and the operation and maintenance are convenient. The several incoming jacks 22 opened at the top of the incoming wire row 20 and matched with the locking bolts 50, as well as the several outgoing jacks 32 opened at the bottom of the outgoing wire row 30 and matched with the locking bolts 50, are arranged evenly and equidistantly for the wires. The access and access provide accurate connection positions; the access jacks 22 on the access line bank 20 and the access jacks 32 on the access line bank 30 are the same in number and have corresponding positions, making the connection more accurate and efficient; the replaceable wire fixing head 40 installed in each access jack 22 and access jack 32 is adapted to the size of the access jack 22 and the access jack 32 and has an interference fit between them, ensuring the stability and reliability of the wire connection; the limiting cap 41 coaxially arranged at the end of the wire fixing head 40 prevents the wire from loosening and falling off; a number of locking bolts 50 evenly and equidistantly arranged provide reliable protection for the fixation of the wire, ensuring the firmness of the line connection.

[0030] Furthermore, a shock-absorbing pad 11 with a thickness of 1-5 mm is installed on the side of the terminal block 10 that contacts the distribution cabinet, which can effectively alleviate the vibration caused by electrical connection or external environmental factors, protect the terminal structure and its internal electrical components from damage, and ensure the stability and safety of the electrical connection.

[0031] Among them, the terminal block 10 is provided with fixing screw holes 12 for fixing to the inner wall of the distribution cabinet, which facilitates its firm installation on the inner wall of the distribution cabinet, improves the stability and reliability of the entire terminal structure, and avoids poor electrical contact or safety accidents caused by looseness.

[0032] It is worth noting that the corresponding input sockets 22 and output sockets 32 are electrically connected via an L-shaped conductive sheet 13, which not only ensures the effective transmission of current but also simplifies the internal wiring structure, making the entire power distribution system more compact and efficient.

[0033] Specifically, the limiting cap 41 and the wire fixing head 40 are coaxial and integrally formed, and both are provided with a wire fixing groove 42 for locking the wire, which can tightly fix the wire and prevent the wire from loosening due to vibration or external force, thereby ensuring the stability and safety of the electrical connection.

[0034] In addition, a first isolation seat 21 for isolating each group of locking bolts 50 is installed on the incoming line bus 20, and a second isolation seat 31 for isolating each group of locking bolts 50 is installed on the outgoing line bus 30, effectively isolating each group of locking bolts 50 and their corresponding electrical connection areas, avoiding mutual interference between different electrical circuits, and improving the safety and reliability of the electrical system.

[0035] The working principle of the terminal structure of this multifunctional distribution cabinet:

[0036] First, the electrician installs the L-shaped terminal block 10 in the power distribution cabinet to ensure that it is firm and stable.

[0037] Next, select the corresponding incoming jacks 22 and outgoing jacks 32 based on the number of wires to be connected. Insert the wires to be connected into the wire fixing heads 40 in the incoming jacks 22 of the incoming wire bus 20. The wire fixing heads 40 are sized to fit the incoming jacks 22 and provide an interference fit. The stop caps 41 at the ends of the fixing heads prevent the wires from falling out. Similarly, insert the wires to be connected into the wire fixing heads 40 in the outgoing jacks 32 of the outgoing wire bus 30.

[0038] Then, use the locking bolts 50 to tighten the wires on the incoming wire bar 20 and the outgoing wire bar 30 respectively to ensure that the wire connections are firm and reliable;

[0039] During use, if the wire fixing head 40 is damaged, it can be easily replaced to ensure the normal use of the terminal block.
