Abstract

The procedure for the manufacture and assembly of electronic boards includes the steps of:

• • arranging a first electronic board (2) having a first power connector (7) of substantially elongated shape;
  • arranging a second electronic board (10) having a through opening (14) suitable for allowing the passage of the first power connector (7);
  • arranging a third electronic board (15) including a power circuit and having a second power connector (18) which can be connected to the first power connector (7);
  • associating the second electronic board (10) with the first electronic board (2), wherein the step of associating includes inserting the first power connector (7) through the through opening (14);
  • associating the third electronic board (15) with the second electronic board (10), wherein the step of associating includes connecting the second power connector (18) to the first power connector (7).

Claims

1. A procedure for the manufacture and assembly of battery chargers for vehicles, comprising the following steps:

arranging at least a first electronic board of a battery charger, the first electronic board having at least a first power connector of substantially elongated shape;

arranging at least a second electronic board of the battery charger, the second electronic board having at least a through opening suitable for allowing a passage of said first power connector;

arranging at least a third electronic board of the battery charger, the third electronic board comprising at least a power circuit and a second power connector connectable to said first power connector;

arranging on said first electronic board at least a first control connector;

arranging on said second electronic board at least a control circuit and at least a second control connector connectable to said first control connector;

associating said second electronic board with said first electronic board, wherein said step of associating comprises inserting said first power connector through said through opening, and connecting said second control connector to said first control connector;

associating said third electronic board with said second electronic board, wherein said step of associating comprises connecting said second power connector to said first power connector;

depositing a thermo-hardening material onto at least one portion of said first electronic board in correspondence to at least one of said first control connector and said first power connector; and

solidifying said thermo-hardening material for locking said at least one of said first control connector and said first power connector onto said first electronic board,

wherein said first control connector comprises at least two metal terminals and said second control connector comprises at least two connection holes, said two terminals being suitable for transmitting one same control signal from said first electronic board to said second electronic board.

2. The procedure according to claim 1,

wherein said at least two metal terminals of said first control connector extend from said first electronic board, and

wherein said step of connecting said second control connector to said first control connector comprises inserting said metal terminals into said connection holes.

3. The procedure according to claim 1,

wherein said first power connector comprises at least one metal blade of elongated shape that extends from said first electronic board and said second power connector comprises a bottom-entry port with at least one housing for the connection of said metal blade, and

wherein said step of connecting said second power connector to said first power connector comprises inserting said metal blade into said connection housing.

4. The procedure according to claim 1, wherein the profile of said through opening substantially reproduces a profile of a transversal section of said first power connector.

5. The procedure according to claim 1, further comprising:

integrally associating at least one guide element (21) with at least one between said second electronic board and said third electronic board and integrally associating rectilinear guide means (22) with said first electronic board,

and wherein said step of associating said second electronic board with said first electronic board and/or said step of associating said third electronic board with said second electronic board comprise the steps of coupling and sliding said guide element (21) on said rectilinear guide means (22).
