Definitions

  • the present invention relates to a connector for ribbon cable, and particularly to improve means for aligning terminals in the housing.
  • Ribbon cable provides a convenient means for handling multiple conductors, and is typically manufactured with conductors on .050 inch (1.27 mm) centerline spacing in a common jacket of insulation. Accordingly, specialized connectors having insulation displacing terminals with slotted plates on .050 inch (1.27 mm) centerline spacing have been developed. Typically, such connectors have two rows of terminals spaced on .100 inch (2.54 mm) centers, the slotted plates in each row being offset from the slotted plates in the other row so that each row of terminals terminates alternate conductors in the cable.
  • An early connector of this type which is sold by AMP Incorporated under the trademark AMP-LATCH, is disclosed in US-A-3 820 555.
  • US-A-4 171 858 discloses a connector for terminating a multiconductor flat cable using insulation displacing contacts disposed in passages of the connector housing.
  • Each contact includes a single barb which bites into the wall of a respective passage to prevent removal of the contact, and a double spring member contact having flared ends.
  • the flared ends of the contact engage a pair of preloading barriers that serve to space the double spring member contacts from each other by a predetermined distance and to center the contacts over an entry aperture.
  • the preloading barriers terminate in the region of the flared ends of the contacts.
  • US-A-4 637 004 discloses an electrical connector of the type comprising an insulative housing having a mating end, a cable receiving end, and a plurality of terminal passages extending therebetween, the passage being of generally square cross-section.
  • the connector further comprises a plurality of stamped and formed terminals received in respective passages, each terminal having a body portion comprising a substantially planar first plate extending to a coplanar slotted plate portion.
  • Terminals as described above generally depend on contact between the three plates of the C-shaped body portion and respective adjacent walls of the passage to angularly position the terminals in the housing.
  • a detent may be stamped in one or more walls to provide an interference fit for retention.
  • stamped dimensions are relative easy to control
  • an oversized formed dimension means that another dimension formed within the same stamped dimension will be undersized.
  • a place of oversized width means that one or two of the other plates will be undersized.
  • an electrical connector of the type comprising an insulative housing having a mating end, a cable receiving end, and a plurality of terminal passages extending therebetween, said connector further comprising a plurality of elongate terminals received in respective passages, each terminal having a body portion of generally C-shaped cross-section, said body portion comprising a substantially planar first plate extending to a coplanar slotted plate portion, said first place having a pair of opposed lugs which engage opposite walls of said passage to secure said terminal in a respective passage, is characterised in that each said body portion further comprises a third plate substantially paral- 'lel to the first plate, said first and third plates having respective cantilever arms extending therefrom to form a mating portion of said terminal, said first and third plates being connected by a second plate extending substantially normally therebetween, each said passage having an elongate rib on one wall thereof, said rib extending from proximate said mating end toward said cable receiving end, with said cantilever arms being loaded against
  • the mating end of the terminal comprises cantilever arms extending from parallel plates of the body portion. Precise angular orientation of the terminal assures that parallel surfaces of the mating ends of the arms will contact opposite sides, rather than edges, of a mating pin.
  • the inventive connector comprises a dielectric housing 10 having a cable receiving end 14, a mating end 16, and a plurality of terminal receiving passages 12 extending therebetween.
  • Each passage 12 is of generally square cross section and has a pair of ribs 20 on opposite walls extending from proximate the mating end 16 toward the cable receiving end 14.
  • a pair of lead-ins 15 in opposed walls of each passage 12 at cable receiving end 14 serve to position terminals 18 received therein, as will be described.
  • Each terminal 18 is stamped and formed from conventional metal strip stock and comprises a body portion 22 of generally C-shaped cross-section having a first plate 24, a parallel third plate 28, and a second plate 26 (in two sections) extending substantially normally therebetween.
  • the first and third plates 24, 28 have respective cantilever arms 34, 36 extending therefrom to contact surfaces 38, 40 for engaging a pin.
  • the first plate 24 is stamped with a pair of opposed lugs 30, 32 which are received in passage lead-ins 15 to align the terminal 18 in passage 12.
  • the first plate 24 further extends to a coplanar slotted plate 42; the slot 48 therein is offset .025 inch from the centerline of plate 24.
  • Figure 2 shows the assembled connector, with terminals 18 loaded in two rows of respective passages 12 of housing 10, the slotted plates 42 extending beyond cable receiving end 14.
  • the slots 18 are spaced at .100 inch in each row and are offset .050 inch from slots 48 in the other row in order to terminate conductors 3 on .050 inch spacing in cable 2.
  • the conductors 3 are aligned relative to housing 10 by flutes 6 in cover 4, the slotted plates 42 being received in apertures 5 to latch the cover 4 to the housing 10.
  • centerline spacing of slots 48 be closely maintained.
  • the passages 12 in each row are directly opposite respective passages in the adjacent row, the offset being achieved by the offset slotted plates 42 and opposite orientation of terminals between rows.
  • the terminals 18 may be installed in the center row of passages in either of two orientations to yield three possible combinations of two rows of terminals to connect with any two of three rows of. pins (see also Figure 3).
  • FIG. 3 shows how terminals 18 are axially positioned in passages 12.
  • Each rib 20 serves to prestress the cantilever arms 34, 36, the contact surfaces 38, 40 bearing against opposite sides of the rib.
  • the rib 20 also serves as a stop to limit insertion depth of the terminal 18 and further serves to withstand the forces imposed during termination of the ribbon cable.
  • Lead-ins 15 receive lugs 30, 32 and serve to position plate 24 flushly against the adjacent wall of passage 12.
  • Figure 4 shows lugs 30, 32 engaged in opposite walls of passage 12. This is in interference fit in the plastic which not only maintains proper angular orientation of the terminal but retains it against withdrawal.
  • Figure 5 is a section view taken through plates 24, 28 between the top and bottom sections of plate 26, showing the engagement of lugs 30, 32 in the housing 10. Clearance between plates 26, 28 and adjacent walls of passage 12 allows for any dimensional variations in forming plates 26, 28.
  • Figure 6 depicts a terminal 54 according to the teaching of the prior art, which terminal comprises a body portion 54 having first, second and third plates 56, 58, 60, respectively, and a slotted plate 72 extending from first plate 58 coplanar therewith.
  • Cantilever arms 64, 68 extend from respective plates 58, 62 and have contact portions 68, 70.
  • Figure 7 depicts the prior art terminals 54 loaded in a housing and illustrates the alignment problem. Since the terminals 54 are received in respective passages in an interference fit between first plate 58, dimple 88 on second plate 60, third plate 62, and adjacent walls of the passage, any dimensional variations in the width of the plates translates into terminal orientation. The terminals may thus end up skewed, adversely affecting the centerline spacing of slots 78. This skewing is exaggerated fof purposes of illustration.
