Definitions

  • This invention relates to a connector adapted for low insertion forces so that a conductor may be connected to or released from the connector with minimal risk of damage.
  • the contact in a relaxed condition admits low force insertion and withdrawal of a conductor and movement of-the housing part towards the passageway deflects the contact to exert contact force on the conductor, the moveable housing part being snap-fitted into a contact engaging position.
  • an electrical connector adapted for low insertion and withdrawal forces on a conductor and comprising a contact mounted in an insulating housing having a passageway for receipt of the conductor, the contact having a spring finger with a contact portion projecting into the passageway and forwardly of the contact portion a forward portion extending in forwardly and outwardly inclined manner from the passageway into a cavity at a side thereof, a housing part bordering a side of the passageway at the side of the cavity and being moveably mounted for movement into the cavity and towards the contact to engage the contact at a surface of the housing part, is characterised in that the housing part is moveably mounted on the housing at a forward end thereof adjacent the forward end of the passageway, the housing part being moveable rearwardly of the passageway to engage the forward contact portion at a surface of the housing part facing away from the passageway to flex the spring finger and move the contact portion outwardly of the passageway to admit the low force insertion or withdrawal of the conductor.
  • Such a connector relies on the resilience of the contact for engaging the conductor and the moveable housing part serves to displace the contact portion from a conductor engaging position during low force insertion and withdrawal.
  • the moveable housing part is integrally formed with the housing at a hinge having an axis extending normally transversely of the passageway and spaced therefrom to allow hinge movement of the housing part into the cavity.
  • the housing part suitably comprises a flap of L-section hingedly formed with the housing at the end of one limb, as is known per se, and the other limb of the L-section extending rearwardly into the cavity to form a side of the passageway.
  • the housing part is suitably secured by interengaging resilient latch means comprising projections and complementary recesses, as is known per se from US-A-3 989 336 the recesses being elongated to accommodate the desired movement.
  • the contact as is known per se for example from the aforementioned US ⁇ A ⁇ 3 989 336 is suitably formed from sheet metal and comprises on a side of the passageway opposite the spring finger a tongue for receipt of the conductor between the tongue and the contact portion of the spring finger.
  • the connector of Figures 1 and 2 comprises an insulating housing 1 formed with a transverse slot 2 defining a passageway for the receipt of flat cable, not shown, having a plurality of parallel conductors.
  • a plurality of contacts 3 are mounted in the housing 1, each contact 3 being mounted in a respective cavity 4 communicating with the slot 2 and extending transversely from the slot at one side as seen in Figure 2.
  • the contacts 3, Figure 3 are stamped and formed from sheet metal and each comprises a post portion 5 projecting through an aperture in the housing for connection to a printed circuit board.
  • each contact has a tab portion 6 bordering the slot 2 on a side opposite that from which the cavities extend and a spring finger 7 on the opposite side.
  • the spring finger extends from the post portion 5 transversely across the flow of the associated cavity as a base portion, then forwardly in parallel spaced relation to the tab portion to a forward bight portion 8 at which it is bent rearwardly to extend in inclined manner towards the tab portion 6 and the slot 2 where it is formed with a further bight 9 defining a contact portion projecting into the slot 2 and convex towards the tab portion 6.
  • the post portion is suitably formed from a slot 51 extending across the base portion and forwardly in the forwardly extending portion but terminating short of the bight 8.
  • the slot 2 On the side opposite the spring finger 7 the slot 2, forwardly of the contact portion 9, is suitably inclined forwardly and outwardly to facilitate entry of a conductor into the slot, and the tab portions 6 are bent to conform to the slot side.
  • the cavities 4 adjacent the bights 8 of the contacts communicate with a common cavity portion 10 extending from the slot 2, and open at the conductor entry side of the housing 1.
  • the housing 1 is integrally formed with a flap member 11 secured to the housing by a hinge portion 12 and adapted to close the open side of the cavity portion 10.
  • the flap member 11 is suitably mounted in the broken-line position, but, after insertion of the contacts 3 into the housing, is hingedly moved into the full-line position.
  • the flap member 11, as seen in Figure 2 is of generally L-shaped section, having a first limb 13 adapted to form a side of the slot 2 forwards of the contact portion 8.
  • a cam surface 15 extends between the limbs 13, 14 in inclined manner to engage the spring fingers 7 at forward portions thereof forwardly of the contact portions 9 and adjacent the bights 8 before the hinge 12 is fully closed.
  • the flap member 11 is formed with spigot- like projections 16 engageable in recesses 17 formed internally of end wall portions 18 of the housing.
  • the recesses 17 are elongated in a direction parallel to the slot and the spigots 16 are suitably engageable in the recesses 17 in a snap fit by resilient outward flexure df the end wall portions 18 to retain the flap member 11 in the closed, full-line position against resilient of the hinge 12.
  • the spigots 16 are suitably chamfered at 19.
  • the housing 1 is so formed with flanges 20 as to enable mounting on a printed circuit board with a slot 2 inclined relative to the board and the posts 5 at 45 degrees.
  • the flap member 11 In use, to connect a flat cable, not shown, having exposed conductive foils, the flap member 11 is depressed, manually, to flex the spring fingers 7 and displace the contact portions 9 away from the tab portions 6, and out of the slot 2, to admit the cable end with minimal insertion resistance. Inclined stop surfaces 21 on the flap are suitably arranged to engage complementary abutments 22 within the housing to limit closure of the flap member 11 and protect against overstress of the spring fingers 7. The flap member 11 is then released to resile under the influence of hinge 12 and of the spring fingers 7, the contact portions 9 being urged against conductive portions of the cable.
  • the particular connector disclosed is intended for use with flat conductors but is usable with discrete wires, in which case the tab portion 6 would be suitably serrated on its inner face.
