[0002] During the construction of a building's electrical system, low-power electrical equipment such as lighting fixtures need to be directly connected to 220V cables. In traditional technology, the connection method between the two is mostly to wrap the cable wires around each other several times and then use insulating tape for isolation and protection. This operation is more troublesome, and it is inconvenient for users to operate when the lamp fails and needs to be replaced later.

[0003] After searching, the patent with announcement number CN214957368U discloses a push-type quick-connect terminal. When in use, it is only necessary to press down the end of the pressing piece to elastically deform the corresponding elastic wire-pressing part to create a gap, and the wire end can be plugged in and out. Release the pressing piece to allow the elastic wire-pressing part to elastically recover. The wiring operation is very fast and convenient, and it has a reasonable structure, few spare parts, simple production and assembly, low cost, strong insulation performance of the shell, and is safe and reliable.

[0004] Although the above solution can achieve quick wiring of low-power electrical appliances such as lamps, some low-power appliances may also need to connect bottom lines, control lines, etc., and since this solution only has two wiring structures, it can only connect two lines. After the user uses multiple terminal blocks to connect the lines of the electrical appliances, it is inconvenient to splice adjacent terminal blocks, resulting in scattered lines that are difficult to organize, and needs to be improved.
