Definitions
- This invention relates to a terminal protector for mulitpolar electrical devices.
- Electrical devices of the automatic circuit breaker type and the like generally incorporate, for the electrical connections, terminals that are housed in the insulating frame of the device, with windows for insertion of the cables to be connected and access holes for driving the corresponding setscrews of the terminals.
- seal cap solutions have been developed, which, however, create problems of mounting for adequate fastening, raising the cost and rendering handling difficult for the installation of apparatus.
- Document GB 2171564 discloses a terminal protector according to the preamble of claim 1.
- a protection that eliminates those disadvantages consisting of an element that is incorporated by simple fitting into the corresponding apparatus, in a sliding assembly that makes easy handling possible, with total safety of the protection for which it is intended.
- This protector object of the invention, consists of a sheet of insulating material, capable of fitting into a groove provided in each zone of inlet and outlet terminals of the application apparatus, said sheet having flanges that make mounting in the housing groove possible, then establishing a retention that prevents exit, with possible sliding motion of the sheet in that arrangement between each of the closing and opening positions of the terminal screw access holes.
- the moving sheet is provided for such purpose with a series of openings that match the arrangement of the terminal screw access holes, said openings being adjacent to respective blind zones that follow the same arrangement, so that when the sheet is shifted toward one side in its mounting arrangement, its openings face the terminal screw access holes, leaving the access to said screws free, while when the sheet is moved toward the opposite side, the blind zones match the terminal screw access holes, thus preventing access to said screws.
- the sheet On mounting, the sheet is totally housed in the frame of the device, the displacements for closing and opening of the terminal screw access holes in that concealed housing being determined without at any time projecting from same, so that the application device can be installed without the need for any free space for the protector on the installation site.
- the movement of the sheet constituting the protector is easily attainable thanks to a small flange accessible from the outside, providing the sheet with a small holes that match one or more other holes in the frame of the device in the closing position of the terminal screw access holes, which makes possible the incorporation of a safety seal to prevent terminal access handling by unauthorized persons.
- this protector object of the invention, certainly has some very advantageous features, acquiring a life of its own and a character preferable to that of other means for the function for which it is intended.
- the invention pertains to a terminal protector for multipolar devices, such as circuit breakers, automatic switches and the like, concretely in order to establish a closure of the access holes (1) for the screws (2) of the terminals of the inlet and outlet connections of the application apparatus (3).
- the protector consists of a sheet (4) of insulating material, intended to fit into a groove (5) defined in the zone of corresponding terminals through the frame of the respective apparatus (3).
- Said sheet (4) is provided with openings (6) that match the arrangement of the access holes (1) for the screws (2) of the connecting terminals, while adjacent to those openings (6) some respective blind zones (7) are defined, which in turn maintain the same relative arrangement as the access holes (1) for the screws (2) of the connecting terminals.
- the sheet (4) On fitting into the corresponding housing groove (5), the sheet (4) is in a sliding position toward the sides of the apparatus (3), with travel limits that prevent the ends of said sheet (4) from projecting outside, but with possible displacement between each of the positions, in one of which the openings (6) match the access holes (1) to the screws (2) of the terminals, leaving access to said screws (2) of the terminals free, as represented in Figure 2, while in the other position, the blind zones (7) match the holes (1), closing off access to the terminal screws (2), as represented in Figure 3.
- the protecting sheet (4) constitutes a moving slide in the zone of application, and can be displaced between the opening and closing positions of the access holes (1) to the screws (2) of the connecting terminals, in order to make possible the operation of said screws (2) and to block access to same once the connections are made.
- the sheet (4) is provided on the front edge with a small flange (8), accessible from outside, the sheet (4) being further provided with a small hole (9) which, in the position in which the blind zones (7) close off the holes (1), matches one or more other respective holes (10) in the frame of the apparatus (3), making possible the placement of a safety cap, to prevent any unauthorized person from moving the sheet (4) and leaving access to the terminal screws (2) free.
- the sheet (4) is further provided with some perpendicular flanges (11) on the back edge, which fit into a guide groove inside when the sheet (4) is introduced in the housing groove (5), establishing a retention that prevents the free extraction of the sheet (4) once inserted, but without impeding the displacement between the closing and opening positions of the holes (1).
- some recesses (12) are provided, with which the flanges (11) of the sheet (4) can be matched, in order to make the insertion with a forced push, until the said flanges (11) fit into the interior guide groove.
