Definitions

  • a connector suitable for making surface contact with a surface conductor of a ribbon-cable or printed circuit board has an open-sided boxlike configuration with a side of the box extended to give a contact edge. The contact edge is bowed and has a free end bent back into the box to reduce entanglement in harnesses.
  • the connector is able to be fitted into a housing and secured to a surface of a panel.
  • An electrical contact for a flat cable is of generally L-form, one limb comprising a wire-receiving part and the other a contact part of generally channel cross section having a floor and sidewalls extending generally normally of the floor defining an open mouth, a cantilever contact blade extending longitudinally of the channel and having at one end a lateral extension integral with one sidewall of the channel, the other end of the blade lying within the open mouth, the contact blade being curved away from the floor between its ends to present an arcuate cutting edge projecting outwardly of the channel.
  • the lateral extension of the contact blade is integral with a sidewall of the channel at a location adjacent the ferrule part.
  • the contact blade preferably comprises a web of substantially constant thickness which is relatively thin in a direction generally parallel to the sidewalls.
  • a connector comprises an insulating housing of generally L-section having channel passageways communicating between the limbs, each passageway having an open slot in the outer lateral, wall of one limb and an aperture in the outer lateral wall of the other limb, engaging means in the inner wall of the apertured limb, the free end of which is formed with latching means for engagement with complementary means on a support to urge the outer wall of the apertured limb against a flat conductor on the support, each passageway containing an electrical contact of the invention, the wire-receiving part being received in the open-slotted passageway and a contact part so held in the apertured limb by the engaging means that the cutting edge of contact blade projects through the aperture for engagement with the conductor.
  • the engaging means preferably and according to an additional object, comprises a latching arm formed from the inner wall of the housing and having a shoulder at its free end.
  • the housing is preferably formed with arcuate projections for latching engagement with complementary projections on the support.
  • This invention includes a connection of a connector in engagement with the support.
  • a connector housing is of generally L-section having contact-receiving channel passageways communicating between the limbs, each passageway having an open slot in an outer lateral wall of one limb, engaging means formed in the inner wall of the apertured limb, the free end of which is formed with latching means for engagement with complementary means on a support to urge the outer wall of the apertured limb against the support.
  • FIG. 1 is a side elevational view of a contact
  • FIG. 2 is an end view of the contact of FIG. 1;
  • FIG. 3 is a perspective view of a housing
  • FIG. 4 is a cross-sectional view through a connector in engagement with a flat conductor
  • FIG. Si is an end view ofan alternative form ofcontact
  • FIG. 6 is a view, partly in section, showing a portion of the dashboard panel
  • FIG. 7 is a view, partly in section, showing the connector partially assembled on the dashboard panel.
  • FIG. 8 is a view, partly in section, showing the connector fully mounted on the panel.
  • the contact of FIGS. 1 and 2 comprises a generally L- shaped member formed of electrically conductive metal, e.g., copper or phosphor bronze, having one limb as contact part 1 and the other as a ferrule part 2.
  • the contact part I is of channel cross section and comprises a generally planar floor 3, FIG. 2, and sidewalls 4,5 extending generally normally of the floor 3 and defining an open mouth 6.
  • a portion 7 is cut out of the sidewall 4 for ease of formation of the contact.
  • Adjacent the angle of the L, an integral extension 8 projects from the edge of the sidewall 5 towards the sidewall 4.
  • a cantilever contact blade 9 integral with the extension 8 extends longitudinally of the contact part I and the free end 10 of the blade 9 lies inside the mouth 6.
  • the blade 9 is of constant thickness along its length and is curved away from the floor 3 between its ends so that an arcuate central portion 11 of the blade 9 extends above the sidewalls 4,5 and thus outwardly of the channel mouth 6.
  • the blade is relatively thin in a direction parallel to the sidewalls so that the portion 11 presents a cutting edge.
  • a flange section 12 extends generally normally of the sidewall 5.
  • the ferrule part 2 has crimping lugs 13 and 14, FIG. 2, respectively for crimping to the conductive core and insulating sheath of an end of a wire 26, FIG. 4.
  • a connector housing 15, FIG. 3, comprises an elongate block of insulating material, conveniently nylon or polypropylene.
  • the housing is generally of L-forrn and has 1 1 channel passageways 16 spaced apart longitudinally of the housing, each to receive a contact of FIGS. 1 and 2.
  • Each passageway 16 comprises a channel extending inwardly from the lateral walls of the housing having an open-ended upstanding open-slot section 17 in the shorter limb and a support section 18 in the longer limb of the L, respectively to receive the ferrule part 2 and contact part 1 of a contact.
  • the inner wall of the section 18 has a flexible latch arm 19, FIG. 4, formed with a shoulder 20 at the junction of the sections 17 and 18.
  • the outer wall of the section 18 is formed with an aperture or slot at 21 to allow reception of the cutting edge portion 11 of the contact blade 9, the slot being dead ended at a location remote from the upstanding section 17.
  • a ledge may be formed in the outer wall of the support section 18 adjacent the upstanding section 17 for supporting the flange 12 of the contact part I.
  • the longer limb of the housing 15 is formed with curved end arms 22,23 adapted to fit under projections 31 of a dashboard panel 28, on which is mounted a flat cable, preferably an insulated printed circuit flat cable, and wedgingly to engage the housing and panel.
  • the arms 22,23 are of different thicknesses and the projections of the panel are correspondingly, dimensioned to polarize the housing and the panel.
  • a stop 24 is formed at the end of the housing 15 remote from the anns 22,23 to cooperate with a corresponding stop, 32 on the panel.
  • the arm 22 is formed with a latch 25 for disengagement of the housing 15 and panel.
  • an end of a wire 26, FIG. 4 is crimped within the ferrule part 2 of a contact.
  • a contact is then inserted into a respective passageway 16 by pressing the ferrule part 2 into the section 17 and the contact part 1 into the section 18.
  • the latch arm 19 is moved away from the outer wall of the section 18, upwardly as shown in FIG. 4, until the contact part 1 is fully home when the shoulder 20 engages behind the end of the floor 3 adjacent the ferrule part 2.
  • the cutting edge portion 11 of the contact blade 9 projects through the slot 21.
  • the connector so formed may then be advanced to a dashboard panel to make electrical contact between the contact blades 9 and the flat conductors 27 on the dashboard panel 28.
  • the arms 22,23 are latchingly engaged with projections on the dashboard panel, see FIG. 8 the pivotal movement of the connectors towards the flat conductors acting to make the cutting edge portion 11 of the contact blades 9 cut through a contaminant insulating film 29 to expose the respective flat conductors 27.
