Terminal block bus structure and bus module thereof

A terminal block bus structure, comprising:

• a rail (30), comprising two wedge sections (31) extended from two sides thereof separately;
• and
• at least two bus modules (100), serially connected with each other and mounted on the rail (30) along a longitudinal direction, and each of the bus modules (100) comprising an insulating body (10) and a plurality of conductors (20) parallelly embedded in the insulating body (10), the insulating body (10) comprising a first insulator (11), a second insulator (12) installed at a position corresponding to the first insulator (11) along the longitudinal direction, and two locking arms (111) disposed on two sides of the first insulator (11) separately, and the locking arms (111) snapped in the wedge sections (31) respectively, and each of the conductors (20) comprising a plate portion (21), a clamping portion (22) and an end pin (23), and the plate portion (21) exposed out of the first insulator (11) and the second insulator (12), and the clamping portion (22) and the end pin (23) coupled to two sides of the plate portion (21) in the longitudinal direction respectively, the clamping portion (22) accommodated within the second insulator (12) and the end pin (23) accommodated within the first insulator (11), and the clamping portion (22) of one of the bus modules (100) elastically clamping the end pin (23) of another one of the bus modules (100).
