Definitions

  • the present invention relates to an electric connector, in particular an electric connector of the type comprising an insulating casing defining a number of cavities, each having a longitudinal axis; and a number of electric terminals housed coaxially in respective cavities and retained inside the cavities by snap-on retaining means.
  • Electric connectors of the above type are also known to comprise a retaining lever, which is hinged integrally to an outer wall of the casing by a short thin connecting blade extending crosswise to the retaining lever and the wall, and comprises, on one end, a first retaining tooth which snaps onto a second retaining tooth carried by a connecting element, e.g. a complementary electric connector, fittable to the connector.
  • a connecting element e.g. a complementary electric connector
  • the retaining lever therefore oscillates about the connecting blade, and is activated manually, at the opposite end to that from which the first tooth extends, to release the first and second tooth and so disconnect the electric connector and respective connecting element.
  • the connecting blade given its small size, may be so stressed as to be permanently deformed - thus resulting in impaired operation of the retaining lever - or even broken.
  • an electric connector comprising an insulating casing defining at least one cavity for housing a respective electric terminal; at least one retaining lever carried by said casing and having first retaining means which snap onto second retaining means carried by a connecting element connectable to said connector; and connecting means connecting said retaining lever in oscillating manner to said casing to permit release of said first and second retaining means and disconnection of said connector and said connecting element; characterized in that said connecting means comprise a beam element fitted integrally at opposite ends to said casing, carrying said retaining lever, and extending crosswise to the retaining lever.
  • Number 1 in Figures 1 and 2 indicates as a whole a hermaphroditic electric connector connectable, in a longitudinal mating direction A, to an identical complementary electric connector 1' ( Figures 3 and 4) to form an electric connecting unit 2. More specifically, when assembling unit 2 ( Figure 4), connector 1' is positioned facing and rotated 180° about direction A with respect to connector 1.
  • connector 1 substantially comprises an insulating casing 3 defining two superimposed rows of through cavities 6 having respective longitudinal axes B parallel to direction A; and a number of hermaphroditic electric terminals 7, which are connected to respective electric cables 8, are housed coaxially inside respective cavities 6, and are retained one-way inside cavities 6 by known snap-on retaining means described later on.
  • casing 3 is substantially parallelepiped, and is defined by two flat parallel base walls 11, 12, and by two lateral walls 13 connected to walls 11, 12 by respective curved lateral edges.
  • Each wall 13 is divided into two flat longitudinal portions 15, 16 of substantially the same height and defining a step 17. More specifically, portions 15 adjoining wall 11 project with respect to respective portions 16.
  • Wall 11 and portions 15 of walls 13 comprise respective longitudinal end portions 20, 21 projecting frontwards with respect to wall 12 and portions 16 of walls 13, and defining as a whole a U-shaped flange 23 of casing 3.
  • flange 23 of each connector 1, 1' slides over wall 12 and portions 16 of walls 13 of the other connector 1', 1 ( Figure 3).
  • Portion 20 of wall 11 comprises a C-shaped cavity 22 extending along a respective front peripheral edge.
  • Casing 3 also comprises an inner transverse wall 25 substantially parallel to walls 11, 12 and extending perpendicularly between mid-portions of walls 13; and a number of inner intermediate walls 26, which are parallel to walls 13, intersect wall 25, and define, with one another and with walls 13 and 25, said two superimposed rows of cavities 6 for housing terminals 7. More specifically, each cavity 6 comes out through a rear opening 27, from which respective electric cable 8 comes out in use, and through a front opening 28 opposite opening 27.
  • each terminal 7 comprises, integrally, a substantially cylindrical intermediate portion 29 of axis B; a connection portion 30 for connection to respective electric cable 8; and a contact portion 31 which cooperates, in use, with the contact portion of an identical electric terminal not shown.
  • Each terminal 7 is inserted inside respective cavity 6 through respective opening 27 and in an insertion direction parallel to respective axis B, so that respective contact portion 31 projects axially from cavity 6 through respective opening 28.
  • Each cavity 6 has a known retaining tooth 32 carried by one of walls 13, 26 laterally defining cavity 6, and which snaps onto the connection portion 30 of respective terminal 7 to retain the terminal one-way inside cavity 6 and prevent withdrawal of the terminal though opening 27.
  • connector 1 also comprises a retaining lever 35 and a tooth 36, which are carried respectively by opposite walls 11, 12 of casing 3, and respectively snap onto an identical tooth 36 and an identical retaining lever 35 carried by identical complementary connector 1'.
  • retaining lever 35 is elongated in direction A, is connected in oscillating manner to wall 11 of casing 3 by connecting means 34, and comprises an integral tooth 37 projecting towards wall 11 from a front end of lever 35 and which snaps onto tooth 36 of identical complementary connector 1'.
  • connecting means 34 comprise a beam element 38, which is fitted integrally at opposite ends to respective lateral edges, parallel to direction A, of wall 11, and is fitted integrally with and extends crosswise to retaining lever 35, which is activated manually to release teeth 36 and 37 and so release connectors 1 and 1'.
  • Retaining lever 35 comprises a retaining portion 39 having tooth 37 and projecting from one side of beam element 38; and a manually operated portion 40 projecting from the opposite side of beam element 38.
  • Tooth 37 has a substantially right-triangular profile, and is defined, towards beam element 38, by a surface 41 substantially perpendicular to direction A, and, on the opposite side, by a surface 42 sloping with respect to direction A.
  • tooth 36 has a substantially right-triangular profile, and is defined, towards electric cables 8, by a surface 43 substantially perpendicular to direction A, and, on the opposite side, by a surface 44 sloping with respect to direction A. Tooth 36 also comprises an intermediate longitudinal groove 45.
  • tooth 37 of retaining lever 35 of connector 1 and tooth 36 of connector 1' snap onto each other along respective surfaces 41, 43.
  • Beam element 38 has an arc-shaped longitudinal section with the concavity facing wall 11 of casing 3, and decreases in width from the opposite ends towards a central portion connected to retaining lever 35.
  • beam element 38 being highly rigid structurally, is capable of withstanding permanent deformation, and therefore practically unbreakable, as a result of repeated connection and release of connector 1, or in the event of severe accidental pressure on retaining lever 35, as when handling connector 1 during production and assembly.
  • connector 1 may be connected to a different type of connecting element - e.g. a printed circuit board or a terminal board of an electronic device - comprising a tooth similar to tooth 36 and designed to snap onto retaining lever 35.
  • connecting element e.g. a printed circuit board or a terminal board of an electronic device - comprising a tooth similar to tooth 36 and designed to snap onto retaining lever 35.
