Definitions

  • This invention relates to electrical connectors and more particularly to electrical connectors for connection with the conductors of ribbon coax cable.
  • Terminated ribbon coax cable assemblies are used to electrically connect electronic circuits of electronic equipment together. These cable assemblies are bent and twisted thereby subjecting them to stresses which cause the signal and drain conductors of the ribbon coax cable to move relative to one another which can result in breakage of one or some of the conductors at the termination sections of the electrical terminals thereby resulting in open circuits which can be difficult to locate. Moreover, after a length of ribbon coax cable has been removed from a roll of cable and its ends have been terminated in electrical connectors, the cable undergoes relaxation whereby more of the exposed ends of the conductors are exposed and these exposed ends can move relative to one another which can cause shorting of conductors within the connectors.
  • a known connector includes a dielectric body member having conductor-receiving passageways along which signal and drain conductors of a ribbon coax cable respectively extend with ends of these conductors being terminated within termination sections of electrical terminals in the body member.
  • Each conductor-receiving passageway has a recess therein which receives a respective projection from a cover member that is secured onto the body member. The projections engage and deform the conductors into the recesses thereby providing strain relief for the conductors.
  • the projections have not provided the desired strain relief on the conductors when the cover members are secured on the body member, because the projections are small and they vary in size as a result of tolerance factors such that they are not able to deform the conductors into the recesses to provide the necessary strain relief thereon. This enables the conductors to therefore move in the conductor-receiving passageways and places stress on the terminations that can result in failure of some of the terminations.
  • an electrical connector for flat transmission cable comprises a body member having terminal-receiving passageways and conductor-receiving passageways. Continuous recesses are located in the body member between the terminal-receiving passageways and the conductor-receiving passageways. Electrical terminals are disposed in the terminal-receiving passageways for terminating electrical conductors of a flat transmission cable which are disposed in respective conductor-receiving passageways and extend across the continuous recesses. Cover members are secured onto the body member and they include projections that extend into respective continuous recesses engaging the conductors therein thereby providing a strain relief for the conductors.
  • the cover members include projections that are disposed on each side of the conductor-receiving sections of the electrical terminals to prevent the electrical conductors from disconnecting from the conductor-receiving sections.
  • the cover members have strain relief members engaging the cable.
  • FIGS 1-4 and 7 illustrate a ribbon coax cable connector 10 for terminating signal conductors 12 and drain conductors 14 of flat transmission or ribbon coax cable 16 which is disclosed in U.S. Patent No. 3,775,552. While ribbon coax cable is being used, other types of ribbon cable having signal and drain conductors can be used.
  • Connector 10 comprises a body member 18 and cover members 20, 21 which are molded from a suitable plastic material.
  • Body member 18 includes a series of terminal-receiving passageways 22 on each side thereof and in which electrical terminals 24 are disposed.
  • Each passageway 22 includes projections 26, 27 in opposing surfaces which mate with corresponding recesses 28 in a body section 30 of terminals 24 to properly position electrical terminals 24 within passageways 22. Projections 27 are deformed onto body sections 30 to stake terminals 24 in position in passageways 22.
  • a post-engaging section 32 of electrical terminal 24 is in alignment with a beveled opening 34 at the front end of body member 18.
  • a conductor-terminating section 36 of terminal 24 is in alignment with a slot 37 in body member 18 and with a respective conductor-receiving passageway 38 in which conductors 12 or 14 are positioned for electrical termination with conductor-terminating section 36.
  • Slots 37 and conductor-receiving passageways 38 are beveled at their entrances to facilitate the positioning of conductors 12, 14 therein. Sloped surfaces 40 are located on each side of body member 18 along passageways 38. Recesses 42 are disposed in each side of passageways 38 and they extend to the bottom surfaces of passageways 38. A continuous arcuate recess 43 is located in each side of body member 18 between slots 37 and passageways- 38 as shown in Figures 1-4. Arcuate recesses 43 extend below the highest level of slots 37 and sloped surfaces 40. As shown in Figure 4, passageways 38 on one side of body member 18 are offset with respect to the passageways 38 in the other side of body member 18 so that the inner end of body member 18 has a square wave configuration.
  • cable 16 is stripped baring only conductors 12, 14 as shown in Figures 1-4 which are then positioned within respective passageways 38, they extend across continuous recesses 43 into slots 37, conductors 12, 14 are then deformed into respective recesses 43 and then terminated in conductor-terminating sections 36 of electrical terminals 24 in accordance with conventional terminating practices. It is also imperative that the end of cable 16 be in engagement with the inner end of body member 18 after conductors 12, 14 have been terminated in conductor-terminating sections 36 to prevent migration of conductors 12, 14 that can short with one another. Thereafter, cover members 20, 21 are secured in place on body member 18.
  • Each of cover members 20, 21 has T-shaped sections 48 at the front end thereof which are disposed in respective passageways 22 and matable within recesses 50 as shown in Figures 2 and 3. Sections 48 complete the outer ends of beveled openings 34 and define pivots about which cover members 20, 21 move when being positioned onto body member 18. Spaced projections 52, -54 extend inwardly from the inside surface of cover members 20, 21 and they are disposed on each side of respective conductor-terminating sections 36 when the cover members are secured in position on body member 18 to maintain conductors 12, 14 in position in conductor-terminating sections. 36.
  • Beveled surfaces 56 of cover members 20, 21 extend along sloped conductors 12, 14 and arcuate projections 58 engage conductors 12, 14 maintaining them into arcuate recesses 43 when cover members 20, 21 are secured in position on body member 18 by rivets 59 thereby defining a strain relief for conductors 12, 14 to maintain them in position in passageways 38 and recesses 42 and in a terminated position within conductor-terminating sections 36 when stresses and strain occur as a result of temperature variations or during the handling of cable 16.
  • Projections 52, 54 also maintain conductors 12, 14 within conductor-terminating sections 36.
  • the continuous form of recesses 43 and projections 58 serve to apply pressure on conductors 12, 14 to maintain them in passageways 38 and terminated in terminating sections 36 of terminals 24 so that they do not move out of the passageways and short one another. If conductors 12, 14 do expand or move because of temperature variation or excess twisting of the cable, part of the conductors 12, 14 can move into recesses 42 to accommodate the movement of the conductors.
  • the continuous form of projections 58 provides a stronger projection for maintaining conductors 12 and 14 in arcuate recesses 43.
  • Wedge-shaped strain relief members 60 which are located on cover members 20, 21 engage cable 16 when cover members 20, 21 are secured onto body member 18 via rivets 59 thereby forming a strain relief when stresses and strains are applied to cable 16.
  • engaging cable 16 function together to maintain conductors 12, 14 within conductor-receiving passageways 38 therefore controlling conductor migration and preventing stresses on the terminations of conductors 12, 14 in conductor-terminating sections 36.
  • Connector 10 is inserted onto posts 70 positioned on printed circuit board 72 or removed therefrom as shown in Figure 7 or matable electrical connectors 10 are connected together within a housing member (not shown).
  • Cover member 20 of connector 10 is provided with projection 62 of which the leading edge is beveled and is a polarizing member for matable engagement within a recess of a housing member.
  • Figures 5 and 6 illustrate an alternative embodiment of body member 18a which is provided with arcuate recesses 64 as part of conductor-receiving passageways 38a on one side of body member 18a to receive therein an exposed end of insulation sheath 66 surrounding signal conductors 12 of cable 16 as shown in Figure 6.
  • Passageways 38a on the other side of body member 18a have the same configuration as passageways 38 of body member 18. Migration of conductors 14 in this embodiment will not short with conductors 12 because of insulation sheath 66 covering conductors 12 and being disposed within recesses 64.
