Abstract

An electrical equipment includes easily separable components, where, in particular, the electrical connections are immobilized by screws in a body, and can be extracted by a simple translational movement when the screws have been removed. The active part can also easily extractable. When combined with the fabrication of an outer body made of thermoplastic material, these features, allowing for easy disassembly, make it possible to easily recycle the equipment, which may be a circuit breaker, a switch, etc.

First claim

The invention claimed is:

1. An electrical switchgear pole, comprising:
an outer body,
an active part retained in a housing of the body, and
connections passing through first and second openings in a wall of the body and extending outside the body and inside the housing,
wherein the connections include portions having constant cross-sections or tapering towards the housing, and are secured in the first and second openings by at least one detachable blocking device that is perpendicular or oblique to the first and second openings, and
wherein the body has at least one third opening formed therein, said at least one third opening being separate from said first and second openings, and the at least one detachable blocking device is accessible through the at least one third opening.

2. The electrical switchgear pole according to claim 1 , wherein the body is made of recyclable material.

3. The electrical switchgear pole according to claim 1 , wherein the at least one blocking device includes screws.

4. The electrical switchgear pole according to claim 1 , wherein at least one part of the at least one blocking device occupies one of the at least one third opening.

5. The electrical switchgear pole according to claim 1 , wherein the body is overmoulded on the connections.

6. The electrical switchgear pole according to claim 1 , wherein the housing of the body comprises an opening for the active part and has a regular cross-section or widening toward the opening.

7. The electrical switchgear pole according to claim 6 , wherein the active part is equipped with sliding collars in the housing.

8. The electrical switchgear pole according to claim 1 , wherein the at least one blocking device secures the connections to the active part.

9. The electrical switchgear pole according to claim 1 , wherein the connections comprise cylindrical outer portions, and inner portions with irregular cross-section, having imbrications in the first and second openings.

10. An electrical switchgear pole, comprising:
an outer body,
an active part retained in a housing of the body, and
connections passing through openings in a wall of the body and extending outside the body and inside the housing,
wherein the connections include portions having constant cross-sections or tapering towards the housing, and are secured in the openings by at least one detachable blocking device,
wherein the connections comprise cylindrical outer portions and inner portions with irregular cross-section, having imbrications in the openings, and
wherein the inner portions comprise grooves extending in an axial direction from the openings, the grooves being filled by the material of the body.
