There are holes at both ends for inserting wires. There are screws for tightening or loosening to achieve the conduction or disconnection of the wires at both ends without welding or twisting them together. It is more convenient and quick. However, when the existing terminal blocks are used for wiring, there is no circuit protector on the terminal block. When the circuit may short-circuit, it may cause the circuit to burn and damage the components. In severe cases, it may cause a fire and is relatively unsafe.

[0003] To this end, a terminal block with the announcement number "CN220042321U" includes an insulating base, at least two wiring groups are arranged on the insulating base, the wiring groups include wiring screws and locking nuts, the insulating base is provided with a mounting groove for installing the wiring screws, and fuses are installed between the wiring groups. Adopting the above technical scheme, the utility model provides a terminal block and a terminal block group, wherein fuses are arranged between the metal conductive sheets, which play a role of insurance for the circuit and improve the safety of use; a detachable positioning sleeve is arranged in the mounting groove of the wiring screw, so that the terminal block can be applied to a variety of wiring screws, and a double row of wiring terminals is arranged on the insulating base, which increases the number of wire access ports, and multiple wires are centrally connected to one component, which is conducive to the bundling of the wires.

[0004] However, for the above-mentioned terminal block, although a removable positioning sleeve is provided in the installation groove of the wiring screw, so that the terminal block can be suitable for a variety of wiring screws, there are still the following obvious defects during use: the wiring method of the above-mentioned terminal block requires the wiring screws to be tightened first, and then the wiring harness is put into the outside of the wiring screw and tightened, so the wiring harness connection process is relatively cumbersome, and it is easy for the copper wire in the wiring harness to be tightened and squeezed out of the wiring screw, resulting in a false connection fault.

[0010] Preferably, the front and rear sides of the upper end of the terminal socket are provided with mounting slots, and the mounting slots are provided with fasteners for snapping the elastic card into the terminal socket for mounting and fixing. The elastic card can be fixed in the terminal socket by the fasteners and is easy to disassemble later.

[0011] Preferably, one end of the terminal holder is inclined and extends outward to provide a clamping portion that is convenient for wire access, and both ends of the copper plate are provided with clamping portions that fit with the clamping portion, so that the wire harness can be elastically compressed after being connected to the terminal without the need for screws to fix it.

[0012] Preferably, a wire inlet for pouring the wires is formed between the side surface of one end of the elastic portion and the two sides of the elastic positioning protrusion, which is conducive to the insertion and pressing of the wire harness, and can completely press and connect the wire harness into the ultra-thin terminal.
