Definitions

  • the present invention relates to an electric terminal, and in particular to an electric terminal of a connector used for an electric vehicle window regulating device.
  • the drive assembly of an electric window regulating device normally comprises a pair of electric terminations connected to the electric system of the vehicle by means of a special connector.
  • the electric connectors used comprise a pair of fork-shaped terminals, i.e. each comprising a pair of flat parallel blades which cooperate with the respective termination so that the termination is inserted interferentially between the blades.
  • a drawback of electric terminals of the above type is the formation of cracks, especially at the base of the blades where stress is most severe, and which soon result in failure of the blades and consequently in the electric contact being cut off.
  • an electric terminal comprising a connecting portion for connection to an electric system; and a contact portion which mates transversely with a substantially cylindrical-pin-shaped electric termination; characterized in that said contact portion comprises a pair of elastic blades facing each other and having respective curved portions with respective concavities facing each other and defining a seat for said termination.
  • Number 1 in Figure 3 indicates an electric connecting assembly for connecting the motor of an electric window regulating device (not shown) to a vehicle electric system (not shown).
  • Assembly 1 comprises an electric connecting member 3 of the window regulating device; and a respective connector 4 which is connected on one side to member 3 and on the other side to the power line.
  • Member 3 comprises a flat supporting plate 6 made of insulating material; and two cylindrical-pin-shaped electric terminations 7 projecting from plate 6.
  • Connector 4 comprises a casing 8 made of plastic material and substantially in the form of a rectangular parallelepipedon; and a pair of side by side electric terminals 9.
  • each terminal 9 comprises a flat intermediate portion 16; a connecting portion 17 for connection to a respective electric cable 13 forming part of the vehicle electric system; and a contact portion 18 designed to mate with a respective termination 7.
  • portion 17 is defined by an elongated body extending integrally from an edge 19 of portion 16, and having a pair of clamps 20 which are crimped onto a bare end portion of cable 13.
  • Portion 18 is defined by a pair of facing elastic blades 21, which are symmetrical with respect to a plane ⁇ ( Figures 5 and 6), comprise respective joining portions 22 joined to portion 16, and extend in the opposite direction to portion 17. More specifically, portions 22 are parallel to each other and extend perpendicularly from respective opposite lateral edges 23 of portion 16.
  • Blades 21 define a cavity 24, and substantially converge from portions 22 up to respective intermediate portions 25 having convexities facing each other and defining the narrowest portion of cavity 24. Blades 21 terminate in respective diverging portions 26 defining a lead-in for respective termination 7, and comprise respective curved contact portions 27 adjacent to portions 25 on the side facing intermediate portion 16, and having respective concavities facing each other to define a seat 28 for a respective termination 7.
  • casing 8 is molded onto a pair of side by side terminals 9 arranged with respective planes of symmetry ⁇ parallel to each other, so as to house the end portions of respective cables 13 and portions 17 of terminals 9. Portions 16 and 18 of terminals 9 project outwards of casing 8, and the distance between the respective planes of symmetry ⁇ of the two terminals 9 equals the distance between the axes of terminations 7.
  • Figures 2 and 4 respectively show a terminal 29 according to a different embodiment of the invention, and a connector 30 comprising a pair of terminals 29.
  • each terminal 29 comprises a contact portion 18 identical to that of terminal 9 (and therefore indicated, together with its component parts, using the same numbering system); an elongated intermediate portion 16' extending in the opposite direction to contact portion 18; and a connecting portion 17' for connection to the electric system, and which differs from portion 17 by comprising a bladelike male contact element 40 extending from one end of portion 16' along a plane perpendicular to plane ⁇ and to the plane of intermediate portion 16'.
  • connector 30 comprises a casing 31, in turn comprising a substantially cup-shaped mating portion 32 defined by an end wall 33, and which mates with a complementary portion of the casing (not shown) of a connector (not shown) forming part of the vehicle electric system.
  • Casing 31 also comprises an appendix 37 extending crosswise and integrally from portion 32 at wall 33, and which partially houses portions 16' of terminals 29 so that elements 40 of terminals 29 extend inside appendix 37, and contact portions 18 project from appendix 37.
  • connector 4 (or 30) is connected to terminations 7 by simply clicking terminals 9 (or 29) onto terminations 7 ( Figures 5 and 6). This is done by resting portions 26 on terminations 7 and pushing connector 4 (or 30) towards terminations 7 to part blades 21 elastically and so insert terminations 7 inside respective seats 28. Stable contact is then ensured by the elastic action of blades 21.
  • Electric terminals 9, 29 according to the invention have the advantage of being less subject to breakage, by being connected to terminations 7 by flexing blades 21 with very little stress which in no way endangers the blades structurally. At the same time, the elasticity of blades 21 ensures constant predetermined grip of terminations 7 to improve the stability and reliability of the connection.
