Terminal box for the electric connection to an electric motor

摘要

A terminal box (45) for electrical connection to an electric motor (32), in particular of a circulation pump (10), includes at least one wall (215) and at least one circuit board (145), wherein the terminal box (45) on the wall (215) includes at least one electrical contact (220) for connection to the circuit board (145), said contact designed as a clamping element (220) for releasably clamping the circuit board (145) which is orientated with its flat sides (150, 152) perpendicularly to this wall (215). A terminal box system includes at least two different circuit boards (145, 145′) selectively insertable into the at least one clamping element (220) of the terminal box (45) and/or at least two different covers (105, 105′) selectively connectable to a housing part (100) of the terminal box (45). A pump assembly (5) includes such a terminal box (45) or such a terminal box system.

主权项

1. A terminal box for electrical connection to an electric motor of a circulation pump, comprising:
a casting of at least one wall (215) of a housing (65) with at least one electrical contact therein; and at least one circuit board (145), wherein the at least one electrical contact (200) is a clamping element (220) releasably clamping the circuit board (145) which is orientated with flat sides (150, 152) thereof perpendicularly to the at least one wall (215), and wherein the clamping element (220) is designed as a pair (200) of resilient clamping tongues (236, 237) which extend perpendicularly from the at least one wall (215) and by way of which the circuit board (145) is clamped on its flat sides (150, 152).
