Problems solved by technology

[0011] Obviously, this solution involves a limited actuation range which requires a rather precise positioning of the actuation key relative to the body of the electrical safety contactor itself, which cannot always be guaranteed in use
[0012] Furthermore, it can be seen that said electrical safety contactors actuated with said movable actuating key currently known have the disadvantage of being bulky, complex and difficult to assemble, especially for mass production by automated production lines when producing parts

Embodiment Construction

[0024] Referring to the above-mentioned drawings, 1 denotes a safety electrical contactor with actuation by a movable actuation key 18 of the present invention.

[0025] According to the illustrated embodiment, the electrical safety contactor 1 comprises:

[0026] - a body 2 of electrically insulating material extending along a predetermined longitudinal X-X axis between the front end 2b and the rear end 2a;

[0027] - wiring means 5 for the wiring of electrical conductors;

[0028] - at least one channel formed in said body 2 for allowing the passage of electrical conductors through said body 2 to carry out the wiring of said wiring means 5 therewith;

[0029] - a first electrical contact 6 located near said rear end 2a of said body 2 and electrically connected to said terminal 5;

[0030] - a movable bridge 7 comprising a second electrical contact 8 for contacting the above-mentioned first electrical contact 6 to establish an electrical connection with said first electrica...

Abstract

The invention provides an electric safety contact (1) with a removable actuation key (18), which comprises a movable hook (11) for engaging the actuation key (18) when inserted into the body (2) of the electrical contact (1), wherein the front end (14) of said movable hook (11) is inclined in a manner to determine a lifting of the movable hook itself if during an initial phase of insertion of theactuation key (18) into the body (2) of the electrical contact (1), this movable hook (11) is in a position not completely lifted in which it interferes with the removable key (18) during its insertion into the body (2).

Description

technical field [0001] The present invention relates to an electrical safety contactor actuated by a movable actuating key, i.e. an electrical contactor in which the closing of said contactor is effected by a movable bridge contained in said contactor body and are non-removable, arranged to ensure actuation towards or away from said electrical contacts by an externally movable actuation key to electrically connect each other. Background technique [0002] Generally speaking, if a so-called waterproof electrical safety contactor is required, it is usually required to be used, although this type of electrical safety contactor is complex and bulky, because the more common electrical safety contacts with movable bridges device is not suitable for this purpose. [0003] In this regard, it is sufficient to point out the problem of how to satisfy the need to insert / remove the terminals of said movable bridge in each actuation cycle within the body of the electrical safety contact,...
