Problems solved by technology

[0007] It has been noted that existing box-type terminals suffer from the following drawbacks: low values ​​of crimping torque that can be applied without causing the terminal to deform, crack, or worse - break
[0008] Over time, various constructions or systems have been developed for sealing or enclosing box-type terminals, which are more or less elaborate, but in a simple system In the case of a cost-optimized but low clamping torque value, or vice versa, in the case of a complex system a higher torque can be achieved but the production costs increase significantly

Embodiment Construction

[0031] Referring to the above-mentioned figures, the terminal according to the invention is generally designated by the numeral 1 and comprises a parallelepiped-shaped body 2 and a clamping screw 3 . The pressing screw 3 is connected with the body 2, so that the end of the conductive cable (not shown in the figure) can be pressed against by acting on the screw, so that the end of the cable is located in the body 2 inside the parallelepiped 2 between the bottom of the connector and the end of the terminal strip (not visible in the figure).

[0032] The parallelepiped 2 is formed from a single metal sheet which has been punched and bent.

[0033] The body 2 is composed of an upper surface 4 and two side walls integrated with the upper surface, the two side walls are respectively a first side wall 5 and a second side wall 6 .

[0034] The end of the first side wall 5 has an inner underside 7 and the end of the second side wall 6 has an outer underside 8 .

[0035] The two under...

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...
