  • The connecting element of the invention exhibits a main body having a planar development and the first terminal, the second terminal, the first tab and the second tab which originate from the same edge portion of the main body; this combination of characteristics enables having a minimum-size connecting element (and therefore more compact with respect to the known element) compatibly with the function which it is to perform.
  • Specific embodiments of the invention will be described in the following of the present description according to what is set out in the claims and with the aid of the appended tables of drawings, in which:
    • figure 1 is a lateral view illustrating a connecting element object of the present invention, which connecting element is fixed to a printed circuit card;
    • figures 2, 3, 4 are respectively a perspective view, a lateral view and a view from above of the connecting element of figure 1.
  • With reference to the appended tables of drawings, (1) denotes in its entirety a connecting element to a printed circuit card (2), object of the present invention.
  • The connecting element (1) is made of a metal material that is tin-solderable to a printed circuit card (2) and which is electrically conductive.
  • The connecting element (1) comprises: a main body (3), comprising a first edge portion (4) and a second edge portion (5), opposite one another; a first terminal (6) which originates from the first edge portion (4) of the main body (3) such as to engage in a first hole (not illustrated) of the printed circuit card (2); a second terminal (7) which originates from the first edge portion (4) of the main body (3) such as to engage in a second hole (not illustrated) of the printed circuit card (2); a first tab (8) which develops perpendicularly from the main body (3) such as to contact a surface of the printed circuit card (2); a second tab (9) which develops perpendicularly from the main body (3) such as to contact the surface of the printed circuit card (2); the first tab (8) and the second tab (9) developing on opposite sides with respect to the main body (3); a third terminal (10) which originates from the second edge portion (5) of the main body (3) and which is conformed such as to engage with an electrical connector (not illustrated).
  • The main body (3) of the connecting element (1) has a planar development, and the first tab (8) and the second tab (9) originate from the first edge portion (4) of the main body (3).
  • The main body (3) has a planar development, and therefore develops parallel to a plane. This ensures the compactness of the connecting element (1), in combination with the fact that the first terminal (6), the second terminal (7), the first tab (8) and the second tab (9) originate from the same first edge portion (4) of the main body (3).
  • The first terminal (6) and the second terminal (7) of the connecting element (1) enable realising the mechanical fixing, by soldering, of the connecting element (1) with the printed circuit car (2). Instead, the first tab (8) and the second tab (9) combine to stabilize the mechanical fixing of the connecting element (1) to the printed circuit (2).
  • The connecting element (1) can carry the electric current between an electrical connector connected to the third terminal (10) and the printed circuit card (2); for example, the connecting element (1) can be made equipotential to the positive pole or the negative pole of the printed circuit card (2). In this case, the surface portions of the printed circuit card (2) which are in contact with the first tab (8) and the second tab (9) will have the same electrical potential as the electrical connector.
  • The connecting element (1) is preferably in a single body.
  • The main body (3) is preferably a plate.
  • The first hole of the printed circuit card (2) is preferably afforded in the surface of the printed circuit card (2); likewise, the second hole of the printed circuit card (2) is preferably afforded in the surface of the printed circuit card (2).
  • The first terminal (6), the second terminal (7), the first tab (8) and the second tab (9) are preferably arranged along the first edge portion (4) in the following succession: the first terminal (6), the first tab (8), the second tab (9) and the second terminal (7).
  • The second terminal (7) is preferably provided with a through-hole (11) such as to enable a friction coupling of the second terminal (7) with the second hole of the printed circuit card (2).
  • The connecting element (1) is moved towards the printed circuit card (2) in a perpendicular direction to the printed circuit card (2) (arrow X1 of figure 1). The coupling of the connecting element (1) with the printed circuit card (2) is completed when the first terminal (6) engages with the first hole, the second terminal (7) engages by friction fitting with the second hole and the first tab (8) and the second tab (9) contact the surface of the printed circuit card (2), see figure 1. The first tab (8) and the second tab (9) are dimensioned and arranged along the first edge portion (4) so as to enable the connecting element (1) to remain perpendicular with respect to the printed circuit card (2) up to completion of the soldering process (preferably a soldering by recasting).
  • The present invention further relates to a printed circuit card group (12) comprising the connecting element (1) and the printed circuit card (2).
  • The first tab (8) and the second tab (9) are preferably soldered to the surface of the printed circuit card (2) by means of surface mounting technology (SMT), wherein the first terminal (6) and the second terminal (7) are soldered to the printed circuit card (2) with a Pin in Paste modality.

The first end (13) soldered to the printed circuit card (2) and the second end (14) soldered to the printed circuit card give a still greater mechanical resistance to the fixture of the connecting element (1) to the printed circuit card (2).
  • In this way, the assembly and soldering operations of the connecting element (1) to the printed circuit card (2) advantageously include the smallest number of steps possible and consequently they are particularly rapid. In fact, the connecting element (1) can be coupled to the printed circuit card (2) as described above; thereafter, the group (12) comprising the connecting element (1) and the printed circuit card (2) can be inserted in an oven at a temperature for example of about 230°C; after the recasting, and once the group (12) has cooled, the connecting element (1) is soldered to the printed circuit card (2).
  • The above has been described by way of non-limiting example, and any constructional variants are understood to fall within the protective scope of the present technical solution, as claimed in the following.
