Definitions

  • the crimping pressure must be sufiicient firmly to fix the lead in position and therefore tends to cause the insulating layer beneath the shield to be extruded so that the cross-sectional area of the insulating layer is reduced beneath the shield, particularly in the Vicinity of the lead.
  • a metal sleeve may be introduced, before crimping, between the insulating layer and the shield.
  • the introduction of the metal sleeve is, however, not only undesirably timeconsuming and diflicult but causes the braid shield to be withdrawn from the end of the conductor to such an extent as to leave a substantial portion of the conductor unshielded.
  • the invention provides an electrical connector comprising a first ferrule-forming portion for crimping about the shield and further ferrule-forming portions for crimping to the lead so that the lead lies alongside the first ferrule-forming portion.
  • the further ferrule-forming portions extend from opposite ends of the ferrule-forming portion. The further ferrule-forming portions can accordingly be crimped without damaging the first ferrule-forming portion and vice versa.
  • FIGURE 1 is a perspective view of an electrical connector according to one embodiment of the invention.
  • FIGURE 2 is a perspective view of the connector shown in FIGURE 1 when crimped to a braid-shielded electrical cable and an insulated electrical lead;
  • FIGURE 3 is an end view of an electrical connector according to another embodiment of the invention.
  • FIGURE 4 is a plan view of the connector shown in FIGURE 3.
  • FIGURE 5 is an elevational view of the connector shown in FIGURES 3 and 4 when crirnped to a braidshielded electrical cable and an insulated electrical lead, the cable being shown in cross-section.
  • an electrical connector 1 for electrically connecting the shield of a braid-shielded electrical cable to an electrical lead, has a first ferruleforming portion 2 which is generally U-shaped as seen in cross-section and has a series of perforations 3 punched therein to provide lances 4 extending inwardly of the portion 2.
  • FIGURE 2 shows an electrical connection in which the portion 2 is crirnped about the bared end of the shield 9 of a braid-shielded electrical cable having an electrically conductive central core 10 insulated from the shield 9 by a layer 11 of insulating material.
  • the lances 4 key into the surface of the shield 9 to prevent displacement of the portion 2 axially of the shield 9 and provide good electrical connection between the shield and the portion 2, the portion 5 being crimped to the electrically conductive core 14 of an electrical lead having an insulating sheath 15 electrically to connect the shield 9 to the core 14.
  • the portion 6 is crimped.
  • the portions 5 and 6 are first crimped to the lead, the portion 2 being subsequently crimped about the shield 9 by crimping dies (not shown), one of which receives the portion 2 and is recessed to accommodate the lead.
  • an electrical connector 16 (FIGURES 3 and 4) comprises a first ferrule-forming portion 17 of generally U shaped cross-section having triangular shaped lances 18 and 19 struck-out from the bight of the portion 17, the lances extending generally parallel to the sidewalls of the portion 17.
  • Two generally axially aligned further ferrule-forming portions 20 and 22 integrally formed with the portion 17 are connected to opposite ends of the bight by goosenecks 23 and 24 respectively, so as to be radially offset from the portion 17.
  • an insulated electrical lead (FIGURE having an electrically conductive core 25, and a braid-shielded electrical cable having a central core 2%, inner insulating layer 2 7, braid shield 28 and outer insulating layer 29, the portions and 22 are initially crimped respectively about the bared end of the core 25 and about the insulation (not shown) of the lead. The cable is then inserted into the portion 17 so that the lances 18 and 1? pierce the outer insulating layer 29 to lie one on each side of the shield 23.
  • the portion 17 is then crimped about the cable, for example, by dies such as those described above, so that the lances l3 and 19 embrace the shield 23, as shown in FIGURE 5, to provide good electrical contact between the portion 17 and the shield 28 and thus between the shield 2% and the core 25.
  • At least one of the further ferrule-forming portions may have an insulation piercing lance (not shown) arranged to be driven through the insulation of the lead to make electrical contact with the core of the lead, when the further ferrule-forming portion is crimped about the insulation of the lead.
  • a sheet metal electrical connector comprising a generally U-section first ferrule forming portion for crimping about a braid-shielded electrical cable and having struck-out therefrom a series of upstanding internal lances adapted to make contact with the braid, second generally U-section ferrule forming portion oppositely directed to the first ferrule forming portion and being of smaller internal cross-sectional area than the first ferrule forming portion, a first resilient neck integrally formed with the first and second ferrule forming portions and extending from one end of each of these portions, a third generally U-section ferrule forming portion of smaller internal cross-sectional area than the second ferrule forming portion and being oppositely directed to the first ferrule forming portion, and a second resilient neck integrally formed with the first and third ferrule forming portions and extending from the other end of the first ferrule forming portion and one end of the third ferrule forming portion, the second and third ferrule forming portions being axially spaced from the first ferrule
  • a sheet metal electrical connector comprising a generally U-section first ferrule forming portion for crimping about the braid of a braid-shielded electrical cable and having struck-out therefrom discrete groups of short upstanding internal lances adapted to key into the cable braid, a second generally U-section ferrule forming portion of smaller internal cross-sectional area than the first ferrule forming portion and directed oppositely thereto, a first resilient neck integrally formed with the first and second ferrule forming portions and extending from one end of each of these portions, a third ferrule forming portion of smaller internal cross-sectional area than the second ferrule forming portion and being oppositely directed to the first ferrule forming portion, and a second resilient neck formed integrally with the first and third ferrule forming portions and extending from the other end of the first ferrule forming portion and from one end of the third ferrule forming portion, the second and third ferrule forming portions being axially spaced from the first ferrule forming portion and being radi
  • a sheet me al electrical connector comprising a first ferrule forming portion having a pair of upstanding sidewalls extending from opposite edges of a web joining the sidewalls, a first upstanding lance struck-out from the material of the ferrule forming portion and extend ing from the junction between one sidewall and the web, substantially parallel to that sidewall, and having a length substantially equal to half the height of that sidewall, a second lance struci -out from the material of the ferrule forming portion and extending from the junction between the web and the other sidewall susbstantially parallel to that sidewall and having a length substantially equal to half the height of that sidewall, a second ferrule forming portion which is generally U-shaped as seen in crosssection and which is of smaller internal cross-sectional area than the first ferrule-forming portion and is oppositely directed thereto, a first resilient neck integrally formed with the first and second ferrule forming portions and extending from one end of the web of the first ferrule forming portion and from one end of the
  • a braid-shielded electrical cable comprising a circular section shield of Woven metal braid, an electrically conductive cable core coaxial with the braid shield, and a layer of insulating material interposed between the core and the shield; and a sheet metal electrical connector comprising a first ferule forming portion crimped about the shield of the cable and having upstanding internal lances in electrical contact with the shield but which do not penetrate the insulating material beneath the shield, a second ferrule forming portion crimped about the insulation of an insulated electrical lead, a first resilient neck formed integrally with the first and second ferrule forming portions and extending from one end of each of these portions, a third ferrule forming portion crimped about the core of the lead, and a second resilient neck formed integrally with the first and third ferrule forming portions and extending from the other end of the first ferrule forming portion and from one end of the third ferrule forming portion, the second and third ferrule forming portions each being axially spaced from
