[0039] Working principle and process:

[0040] Installation process:

[0041] Connection between the mounting base and the guide rail: Align the two L-shaped clips 6 on the lower end face of the base 3 of the terminal mounting base 1 with the guide rail, and press the base 3 in the direction of the guide rail. Since the L-shaped clips 6 have elastic deformation capability, they will elastically deform during the pressing process. When the base 3 moves to the appropriate position, the L-shaped clips 6 return to their original shape and lock with the guide rail, thereby fixing the terminal mounting base 1 on the guide rail.

[0042] Connection of terminal block unit 2 to mounting base: According to actual needs, install the corresponding number of terminal block units 2 onto the terminal block mounting base 1. Align the locking block 9 of the terminal block unit 2 with the locking slot 7 on the mounting groove 4, and push the terminal block unit 2 into the mounting groove 4. The locking block 9 undergoes elastic deformation under the pressure of the locking slot 7. When the locking block 9 moves to the appropriate position of the locking slot 7, the locking block 9 returns to its original shape and locks with the locking slot 7, thereby fixing the terminal block unit 2 onto the terminal block mounting base 1.

[0043] Wiring process:

[0044] Wire introduction: The wire to be connected is introduced from above the wire inlet hole 8 of the terminal unit 2. Under the guidance of the guide ring 15, the wire smoothly enters the wire inlet hole 8 and falls on the conductive end of the conductive sheet 11.

[0045] Wire clamping: Rotate the two clamping bolts 10 on the vertical section of the terminal block 2. The two clamping bolts 10 move into the wire inlet hole 8, which drives the arc-shaped positioning plate 14 to move towards each other. The arc-shaped positioning plate 14 clamps the wire, ensuring that the wire is in contact with the conductive end of the conductive plate 11 and ensuring a good electrical connection between the wire and the conductive plate 11.

[0046] External connection: Insert the wires or connecting wires of other electrical devices that need to be connected into the wiring holes 12 of the conductive sheet 11, and fix them by bolts or welding, thereby achieving electrical connection.

[0047] The rail-mounted terminal block of this invention has the advantages of convenient installation, flexible adjustment of the number and position of terminal block units, stable connection with the guide rail, and reliable conductive connection.
