Abstract

An improved terminal for automatic circuit breakers, is formed by a metal strip which is blanked and bent so as to form a parallelepipedal body, with which an abutment screw is associated, the body is constituted by two side walls, an upper surface, and a lower surface; the lower surface is constituted by the ends of the plate which are mutually joined by two joining points.

Description

technical field

[0001] The present invention relates to an improved terminal, especially for use in automatic circuit breakers. Background technique

[0002] As is known, for terminals used in electrical equipment - especially modular automatic circuit breakers, the main function required is usually: to hold a rigid or flexible electrical conductor by means of a screw, so that it abuts against the terminal set The wiring board or terminal strip inside, so as to achieve a stable and firm circuit connection.

[0003] This type of connection must ensure the following properties: it has a contact surface suitable for the current capacity; it does not lose its mechanical retention after long-term use; and, after the cable is clamped, it must not be damaged. To such an extent - its current-carrying cross-sectional area is less than the limit set by the standard.

[0004] According to the prior art, box-type terminals are produced by bending a strip or strip made of steel or equi...
