DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the embodiment of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings of the embodiment of the present invention.

[0023] The multifunctional modular terminal block in this embodiment has a structure as follows: Figures 1 to 5 As shown, it includes an insulating housing 1 and a terminal block 2 disposed inside the insulating housing 1; the insulating housing 1 is provided with a mounting structure, and the modular terminal block is installed via the mounting structure. The terminal block 2 includes a conductive bar 21 positioned within the insulating housing 1 and a plurality of wiring terminals disposed on the conductive bar 21; the side wall of the insulating housing 1 is provided with a plurality of wire holes 12 for allowing wires to extend into the interior of the insulating housing 1. By disposing the terminal block 2 inside the insulating housing 1, the insulating housing 1 can provide a shielding and protective function, enhancing safety in use. When wiring, the wires are connected to the terminal block 2 through the wiring terminals. The provision of multiple wiring terminals can accommodate the connection of multiple wires. The conductor 21 is preferably made of copper bar, which has excellent conductivity.

[0024] Specifically, such as Figure 4 and Figure 5 As shown, the terminal block includes a plurality of wiring frames 22 sleeved on the conductive bar 21, and the wiring frames 22 are rectangular frame structures. A clamping screw 23 is screwed on the upper part of each wiring frame 22; an operating hole 11 is provided at the top of the insulating shell 1 corresponding to each clamping screw 23, so that when wiring, the end of the wire is inserted into the wiring frame 22, and then the clamping screw 23 is tightened to press the wire onto the conductive bar 21 through the wiring frame 22. A screwdriver is inserted into the operating hole 11 to screw the clamping screw 23, and the wiring operation is convenient.

[0025] In order to facilitate the assembly of the terminal block 2 into the insulating shell 1, the insulating shell 1 adopts a split structure. The insulating shell 1 is composed of two half shells 18 connected together. The two half shells 18 can be fixed together by screw fastening, glue bonding or ultrasonic welding.

[0026] like Figure 5 As shown, the conductive bar 21 is arranged along the length direction of the insulating housing 1, and multiple wiring frames 22 are arranged along the length direction of the conductive bar 21. This helps to reduce the width of the modular terminal block, thereby adapting to installation in a small space.

[0027] In a further embodiment, in order to facilitate wiring, the insulating shell 1 is provided with a wire hole 12 at each wiring frame 22, and the wiring frame 22 has a wire entry hole 24 opposite to the wire hole 12. In this way, during installation and use, the end of the external wire can be passed through the insulating shell 1 through different wire holes 12, and extended into the wiring frame 22 at the corresponding position through the wire entry hole 24 for wiring.

[0028] In a further embodiment, an accommodating cavity 13 is provided in the insulating shell 1 at a position corresponding to each wiring frame 22, and the wiring frame 22 can move up and down in the accommodating cavity 13, so that by screwing the wire-pressing screw 23, the wiring frame 22 is driven to move up and down relative to the conductive bar 21 in the accommodating cavity 13, thereby expanding and shrinking the gap between the wiring frame 22 and the conductive bar 21, and the wire can be clamped when shrinking, and the wire can be loosened when expanding; a partition rib 14 is formed between adjacent accommodating cavities 13, and a positioning slot 15 is provided on the partition rib 14 for clamping the conductive bar 21, and the conductive bar 21 is clamped by the positioning slot 15, thereby ensuring that the terminal block 2 is quickly and effectively positioned inside the insulating shell 1.

[0029] like Figure 2 As shown, in some embodiments, the conductive strip 21 is provided with a screw hole 25 connected to the grounding screw, and the bottom of the insulating shell 1 is provided with a screw through-hole 16 for the grounding screw to extend into. In this way, when the modular terminal block is grounded, the grounding purpose can be achieved by cooperating with the grounding screw connected to the external grounding member (such as a metal rail) and the screw hole 25 on the conductive strip 21.

[0030] More specifically, the mounting structure is a mounting slot 17 provided at the bottom of the insulating housing 1 and suitable for being clamped to a rail. Thus, during installation, the mounting slot can be clamped to a metal rail in the distribution box, making installation convenient.

[0031] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to enumerate all embodiments here. However, obvious variations or modifications arising from the essence of the present invention remain within the scope of protection of the present invention.
