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.
- a connector adapted for low insertion or withdrawal forces on a conductor comprises a contact mounted in an insulating housing having a passageway for receipt of the conductor, the contact having a spring finger presenting 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 is characterised by a housing part bordering the side of the passageway and moveably mounted on the housing adjacent the forward end of the passageway, the housing part being moveable into the cavity 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.
- the 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 is suitably secured in the cavity by interengaging resilient latch means which may comprise projections and complementary recesses, the recesses being elongated lengthwise of the passageway to accommodate the desired movement.
- resilient latch means which may comprise projections and complementary recesses, the recesses being elongated lengthwise of the passageway to accommodate the desired movement.
- the contact 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 floor 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.lO 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 10.
- the flap member 11 is suitably moulded 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 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 of the end wall portions 18 to retain the flap member 11 in the closed, full-line position against resilience 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 the 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.
