Electric power distribution box comprising a system of compacting the integral elements thereof
View Patent ↗The invention, electrical distribution box with compacting system for its integral elements, consists of an electrical distribution box, suitable for being used preferably in automobiles, which has the means for insulating the conductor block housed in it, generally made up of several printed circuit boards, and of carrying out a solid fixing between them and the box, so that they react as one to the tensions caused by the vibrations in the vehicle during its operation, preventing it from being affected by said tensions.
1. An electrical distribution box with compacting system for its integral elements, suitable for being used in a vehicle, comprising:
a box having a body, and a cooperating fixing means protruding from a bottom surface of said body;
first and second printed circuit boards which make up an electrical distribution system of the vehicle positioned within said body;
a lid for providing said body with an isolation for its internal field, and a cooperating fixing means protruding from a bottom surface of said lid;
a separating element in a form of a laminated board, said separating element interposed between said first and second printed circuit boards, said separating element has on each one of its surfaces a protuberance in a form of a horn, and a plurality of troncoconic protuberances for coming into contact with said first and second printed circuit boards and providing a space between said first and second printed circuit boards and the separating element; and
wherein said cooperating fixing means of the body, said cooperating fixing means of the lid and said horns are in coaxial alignment.
2. The electrical distribution box, according to claim 1 , wherein the cooperating fixing means of the body comprises a centered and solitary vertical shaft for providing a support base to the first and second printed circuit boards and establishing a separation between the body and said second printed circuit board.
3. The electrical distribution box, according to claim 2 , wherein the bottom surface of the body having a plurality of cylindrical objects distributed jointly on the aforementioned bottom surface for cooperating in the maintenance of the first and second printed circuit boards, and exerting pressure on them.
4. The electrical distribution box, according to claim 2 , wherein the vertical shaft having a threaded blind passage for receiving a thread as a means of tightening.
5. The electrical distribution box, according to claim 4 , wherein said tightening means comprises a screw.
6. The electrical distribution box, according to claim 5 , wherein the cooperating fixing means of the lid comprises a solitary shaft, said shaft having an assistant axial passage, said assistant axial passage having an enlarged portion adjacent to an external surface of said assistant axial passage.
7. The electrical distribution box, according to claim 6 , wherein a portion of said assistant axial passage for receiving a body of said screw and the enlarged portion of said passage for housing a head of said screw.
8. The electrical distribution box, according to claim 7 , wherein said shaft of said lid establishes a separation between the second printed circuit board and the bottom surface of the lid, wherein the bottom surface of the lid having a plurality of cylindrical objects distributed jointly on the aforementioned bottom surface for cooperating in the maintenance of the aforementioned boards, and exerting pressure on them.
9. The electrical distribution box, according to claim 8 , wherein each of the first and second printed circuit boards has a passage for allowing the body of said screw through.
10. The electrical distribution box, according to claim 9 , wherein the printed circuit boards have non-conductive portions for allowing contact with the cylindrical objects of the body and the lid and said troncoconic protuberances of said separating element.
11. The electrical distribution box, according to claim 10 , wherein said screw has a cylindrical body, a cylindrical head and a threaded end, for being introduced into the lowest diameter passage of the shaft of the lid element, through the first printed circuit board, between the separating element and through the second printed circuit board, until the threaded end is housed in the threaded blind passage of the shaft of the body, and the cylindrical head supported by the enlarged portion on the assistant axial passage of the shaft of the lid, and exerting traction on the body so that between both shafts, they put pressure on the intervening boards and separating element, creating a compacting between them, helped by the cylindrical objects.
