AI Technical Summary

Technical Problem

Existing terminal blocks require a long stroke for inserting cables, causing inconvenience and increasing the overall size of the device.

Method used

A terminal block design featuring a lever mechanism that allows for a shorter stroke operation by rotating a lever connected to a rotating portion, which pushes elastic pieces to insert cables with a reduced displacement, thereby reducing the overall size.

Benefits of technology

The design simplifies cable insertion and reduces the overall size of the terminal block by requiring a shorter stroke, enhancing operability and user experience.

Abstract

A terminal block (1) includes a base (10) having a receiving space (100), an installation opening (11), an insertion opening (12), and a through-hole (13). A rotating portion (14) is formed adjacent to the installation opening (11). An elastic piece (20) includes a bending portion (21), a movable elastic arm (22), and a resistance arm (23). The movable elastic arm (22) and the resistance arm (23) each extend from two sides of the bending portion (21), and the bending portion (21) surrounds the rotating portion (14). The resistance arm (23) includes a hook (231) disposed on a side thereof facing the movable elastic arm (22), and the movable elastic arm (22) is pressed to engage with the hook (231). A conductive terminal (30) includes a conductive portion (31) and a conductive lead (32).The conductive portion (31) contacts the resistance arm (23), and the conductive lead (32) is arranged corresponding to the through-hole (13). A lever (40) is assembled in the installation hole (11), rotatably connected to the rotating portion (14), and exposed from one side of the insertion hole (12). The lever (40) rotates and slides the movable elastic arm (22) under an external force. A cable (3) is inserted through the insertion hole (12) into the receiving space (100) such that it is electrically connected to the at least one conductive lead (32). Therefore, it is easy to slide the lever (40) of the terminal block (1), and the size of the terminal block (1) is reduced.
