(57) An assembly for electrical connection, start up and protection from excessive current
absorption and/or overheating of an electrical moto-compressor contained in a sealed
metal shell (2) and connectable through electrical pins (5, 6, 7) protruding out of
a dielectric pane or fusite (4) integrated in the metal wall of the shell (3), comprises a connection unit and
a docking metal bracket (3) adapted to be pre-welded to the shell (2), a dielectric
body (1) of plastic material of said connection unit having installed therein a plurality
of electrical terminals (m1-m14) for the connection of electrical wires of a power
cable and of electrical wires of connection of external or remotely installed electrical
components of circuits of the appliance. The connection unit is completely pre-fabricated
and comprises a motor start up device (PTC) and a device of protection (OLP) from
excessive current absorption and/or overheating of the moto-compressor hosted in recesses
of the dielectric body (1) of plastic material. A plurality of electrical connection
metal lamine have terminations adapted to constitute an electrical terminal board
(m1-m14), plug-on sockets (5f, 6f, 7f) for the connection pins of the fusite and (8f) for a ground connection pin (8) projecting from a surface of the metal bracket
(3) parallel to said pins (5, 6, 7) upon docking the connection unit onto it. A dielectric
shroud (19) of plastic material has first engagement means (18f) adapted to slidely
engage with said body and second engagement means adapted to engage underneath raised
and outwardly bent parallel edges (9-12) of the metal bracket for blocking the connection
unit onto the docking bracket while allowing sliding displacements of the shroud (19).
Guillotine-type cable stopper devices (15, 21) arc integrally formed and extend from
the slideable shroud.
Optionally the slideable dielectric shroud (19) comprises a removable end cap (23)
of molded plastic having engagement spikes (24) adapted to slide in and be retained
in cooperating channels (24f) formed in the slidable shroud (19) as far as abutting
against end surfaces thereof and further having an elastic inner hook (28) adapted
to engage itself into a locking recess (14) of the metal bracket (3).
