Problems solved by technology

However, an assembly implemented in this way is complex and costly to implement, and in particular requires improvements to the circuit breaker 2 dedicated to the differential protection unit 10
[0008] Thus, although the method for assembling the differential unit 10 to the circuit breaker 2 has improved in terms of assembling the two units relative to each other, the step of securing each conductor 14 in the terminal 6 remains

Embodiment Construction

[0019] In electronic panels and / or cabinets, electronic protection systems 1 are usually mounted on horizontal rails 4, such as figure 1 shown. In the rest of the description, different positional terms ("upper", "bottom", etc.) will be used with respect to this position of use, but it should naturally be understood that they are not limiting.

[0020] In a preferred embodiment, the protection system 1 comprises a four-pole circuit breaker 2, constructed with four similar modules 21, 22, 23, 24, assembled side by side on a rail 4 and fastened to each other. Each module is housed in the housing 3 and comprises terminals 6 a , 6 b for connection on the conductors of the circuit breaker 2 on each side of the rail 4 . This protection system 1 also includes a differential unit 10 housed in a housing 12 , which has a cross-section similar to that of the module 2 .

[0021] In a known manner (see for example EP 0 375 568 or EP 0 926 695), the trip unit 10 houses a transformer with ...

Abstract

In order to assemble a differential trip unit (10) and a circuit breaker (2) provided side by side on a track (4), the first step preferably comprises the electric connection of a connection assembly (50) in the housings (7), and a translation movement (d) of the connection assembly (50) results in a mechanical connection during a second step. To this end, a device (20) was developed for quick connection via pins, wherein said device includes a planar conductor portion (22) provided with projections (42) and urged by a spring (26) towards a connection pad (8) of a housing terminal (6). This configuration prevents the repulsion generated by a short-circuit current in a circuit breaker (2) and maintains the contact between the conductors (8) of the circuit breaker (2) and the conductors (22, 52) connected to the differential protection unit (10) without any screwing action.

Description

technical field [0001] The invention applies in particular to assemblies between two electronic units arranged side by side on rails in an enclosure, in particular differential trip units associated with circuit breakers, each unit connected at the level of the side panels and Each pole included on the surface perpendicular to the connection plate has a connection terminal. [0002] The invention also relates to a device for quick connection of an electronic equipment unit to a conventional open pipe terminal by insertion, ie a terminal comprising a flat connection strip located in a through hole. Several connection means can be associated to enable simultaneous connection of multiple terminals of the electronic unit. [0003] The invention also relates to a unit, such as a residual differential current protection unit, or a differential unit, provided with an attachment, a part of which includes connection means sliding to achieve a continuous electrical and mechanical conne...
