• facing ' in ⁇ use the fl ⁇ id-tigl ⁇ t: ' teritiinal " and ' positioned at an angle with respect ' " to ' the first open side.
• the device further comprises a second supporting element consisting of a metallic bracket' ' (F ⁇ site shield), onto which the first supporting element is fittable in a ' removable way; the second supporting element surrounding said fluid-tight terminal and being integral with the same.
• a second supporting element consisting of a metallic bracket' ' (F ⁇ site shield), onto which the first supporting element is fittable in a ' removable way; the second supporting element surrounding said fluid-tight terminal and being integral with the same.
• a snappingly closing cover for the first open side is integrally connected to the first supporting element, on the part of the first open side, by at least one plastic hinge defined by a flexible tongue.
• blade contacts also comprise an earth contact protrudingly and transversally arranged with respect to the same and couplable, by at least one screw, with a fin integrally made with said second supporting element, perpendicular to a laying plane of said fluid-tight terminal.
• the blade contacts may be pre-assembled with the a starter and/or protector device housing forming with it a single unit ' fittab'le in the ' first' support element and such unit may indifferently accommodate 'a ; PTC tablet or an E- starter; above all, the connection ends of the blade contacts remain arranged all in the same frontal position, at the first open side of the first box-shaped supporting element, which may be easily shaped to define ' a ' standard multiple connector, and the earth ' connection of the' carcass of the compressor, through the bracket (Fusite shield) constituting the second supporting element of the device of the invention, is also very simple and rapid.
• the traditional terminal board is transformed from a self-standing element into a complex terminal board device ' integrated with the Fusite shield, thus reducing and simplifying assembly.
• the device 1 • comprises a first support element 5 made of electrically non-conductible material, typically by synthetic plastic material moulding, a plurality of electrical contacts 6 of the blade type, all accommodated in use within the supporting element 5, wire clamp means, indicated as a whole by 7, and a housing 8 for a protector and/or starter device, known and not shown, for the compressor 4.
• the housing 8 is shaped so as to be adapted to contain either a PTC tablet or an E-starter, both known and not shown for the sake of simplicity.
• the housing 8 is also arranged within the first supporting element 5, next to the blade contacts 6.
• the first supporting element 5 is box-shaped and the blade contacts 6 present same protruding connection extremities 10, all turned towards a same first open side 11 of the first supporting element 5;
• the wire clamp means 7 are arranged immediately adjacent to said first open side 11 and the housing 8 faces toward a second open side 12 of the supporting element 5, facing in use the fluid-tight terminal 2 and positioned at an angle (more precisely perpendicular) with respect to the first open side 11.
• the first open side 11 is therefore arranged so that, in use, it is positioned at an angle (i.e. not on the same plane or on a parallel plane) with respect to a laying plane of the fluid-tight terminal 2, defined in the case in point by a metallic bracket 20, or Fusite shield, arranged substantially tangent to the side wall of a metallic carcass 21 of the compressor 4.
• the device 1 further comprises a snappingly closing cover 25 for the first open side 11, which cover 25 is integrally connected to the first supporting element 5, on the part of the first open side 11, by at least one plastic hinge defined by a flexible tongue 26, in the case in point by two tongues 26 adjacent to a same edge of the open side 11.
• the metallic bracket 20 or Fusite shield defines a second supporting element of the device surrounding said fluid-tight terminal 2 and being integral with the same; the first supporting element 5 is removably fittable to the second supporting element 20; for example, the box-shaped supporting element 5 presents a third open side 27, arranged facing to and on the opposite band of said first open side 11; and the metallic bracket 20 presents: a bottom wall 30, through which said fluid-tight terminal 2 is throughly housed, defining in use a closing wall of the second open side 12; a side wall 31 essentially perpendicular to the bottom wall 30 and defining in use a closing wall of the third open side 27; and a pair of edges 32 L-shaped folded and essentially arranged perpendicularly with respect to the bottom wall 30 and the side wall 31 and provided with first snappingly fastening means 34, for example perforations, for second snappingly fastening means 35, for example teeth, complementary with the first, carried by the first box-shaped supporting element 5.
• first snappingly fastening means 34 for example per
• the latter is preferably shaped so as to receive the blade contacts 6 for sliding insertion through said third open side 27, with the protruding extremities 10 of contact being arranged in use essentially flush with the first open side 11.
• the blade contacts 6 also comprise an earth contact 60 protrudingly arranged transversally with respect to the same and couplable, by at least one screw 61, with a fin 62 integrally made with the second supporting element constituted by the bracket 20, perpendicular to a laying plane of the fluid-tight terminal 2, coinciding with a laying plane of the bottom wall 30 of the bracket 20.
• the bracket 20 which constitutes the second supporting element of the device 1, is electrically and mechanically connected to the carcass 4, so that the connection of contacts 60 and 62 causes the automatic connection to earth of the carcass 4.
• the bracket 20 is integral not only with the compressor, through the carcass 4, but also with a supporting base 40 of the same; the wire clamp means 7 may be made of a synthetic plastic element independent of the supporting element 5 and fastened in use to an edge 41 of the supporting base 40, facing the same band on the open side 11 of the box-shaped supporting element 5.
• the wire clamp means 7 are integral with the cover 25 and are integral with an edge of the same, so as to be positioned, with the cover 25 closed, in a recess 44 of the same supporting element 5 made at the first open side 11.
