Definitions

  • An electrical termination arrangement for flat cables which includes a generally U-shaped metallic member for each conductive track of the cable.
  • Each metallic member has barbs formed onits legs which pierce the insulation and make electrical contact with the conductive track when the legs of the member are crimped to the flat cable.
  • the U-shaped member may carry a pin or socket contact.
  • the U- shaped member may be provided with an additional leg forming a Z-shaped member which interconnects the tracks of two flat cables.
  • the present invention relates generally to flat cable terminating and, more particularly, to electrical termination arrangements for flat cables and the method of terminating such cables.
  • the present invention has special utility in the termination of conductive tracks of flexible flat electrical cables commonly known as strip cables wherein the tracks are covered with insulation.
  • the invention is also applicable of joining of a pair of flat cables together.
  • the purpose of the present invention is to provide an electrical termination arrangement and method for terminating flat cables which is less expensive and easier to perform than the aforementioned prior art flat cable terminating techniques.
  • an electrical termination arrangement for a flat cable which includes a generally U-shaped deformable metallic strip member for each conductive track of the cable to which contact is to be made.
  • Each metallic member has a pair of flat, generally parallel legs. The cable is inserted between the legs of the metallic member with its conductive track aligned therewith. The legs of the metallic member are formed with barbs. The legs are crimped together so that the barbs pierce the insulation of the cable and make contact to the conductive track therebetween.
  • the U-shaped member also includes means for making contact to a further conductor.
  • Such means may be either a pin contact or socket contact on one of the legs, or a third leg parallel to the first two legs forming a Z-shaped member for interconnecting'two flat cables, each cable being inserted between a pair of adjacent legs of the Z- shaped member.
  • FIG. 1 is a perspective view of the Z-shaped electrical termination device of the present invention with the ends of two flat cables shown in position to be inserted into the device;
  • FIG. 1a is a transverse vertical sectional view taken along line 1a-1a of FIG. 1 illustrating the details of the structure of one of the flat cables, the thickness of the cable being somewhat exaggerated for purposes of illustration;
  • FIG. 1b is a vertical sectional view taken along line 1blb of FIG. 1 showing the barbs on the termination device;
  • FIG. 2 illustrates the Z-shaped termination device of FIG. 1 crimped to the ends of the flat cables with the portions of the termination device between the conductive tracks of the cables removed;
  • FIG. 3 is a perspective view of a U-shaped termination device having socket-type contacts thereon and crimped to the end of a flat cable in accordance with the present invention, with the device shown positioned to be inserted into an electrical connector housing;
  • FIGS. 4 and 5 are perspective views showing the two forms of socket-type termination devices utilized in the termination arrangement illustrated in FIG. 3;
  • FIG. 6 is a perspective view of a pin contact termination device suitable for use in the arrangement illustrated in FIG. 3.
  • the arrangement includes a termination device 12 for electrically connecting the conductive tracks 14 of a pair of flat cables 16 and 18 arranged with their respective tracks aligned with each other. As well known in the art, the conductive tracks are covered by insulation 20.
  • the termination device 12 comprises a deformable flat metallic sheet bent to a Z-shaped configuration providing three generally parallel legs 22, 24 and 26. The metal sheet may be copper or alunimun, plated or unplated as desired.
  • the width of the termination device 12 is such as to embrace all the conductive tracks of the flat cables 16 and 18.
  • the sheet Prior to bending the sheet to form the Z-shaped member 12, the sheet is stamped to provide parallel spaced apart rows 28 of barbs, one for each conductive track on the flat cables.
  • the rows 28 of barbs are spaced apart a distance corresponding to the spacing of the tracks 14.
  • the pair of adjacent legs of the termination device 12, namely, legs 22, 24 and legs 24, 26, are spaced apart a distance sufficient to allow the ends of the flat cables 16 and 18 to be inserted therebetween.
  • the barbs 28 may be V- shaped, as shown, and are designed to be able to pierce the insulation 20 of the flat cables 16 and 18.
  • the cable 16 is inserted between the legs 24 and 26 of the termination device 12, with each of its conductive tracks 14 aligned with the rows 28 of barbs on the device.
  • the second flat cable 18 is inserted between the legs 22 and 24 with its conductive tracks aligned with the rows of barbs on the termination device 12.
  • the legs of the Z-shaped termination device are then crimped or squeezed together, so that the barbs on eachrow pierce the insulation 20 of the flat cables to make contact with the respective conductive tracks thereof.
  • FIG. 3 The arrangement illustrated in FIG. 3 is similar to that illustrated in FIGS. 1 and 2, and like members primed are used to indicate like or corresponding parts.
  • the termination members 30', 30'a are U-shaped in configuration and are crimped over the conductive tracks 14 of a single flat cable 16'. The areas between the termination members are removed to electrically isolate the conductive tracks of the flat cable as in the embodiment illustrated in FIG. 2.
  • the termination members 30 and 30'a are integrally formed with socket contacts 40. Alternate termination members are inverted. As seen from FIGS. 4 and 5, the termination member 30' differs from the member 30'a by the inclusion of a relatively wide base section 42. The termination members 30 are utilized at the edge of the flat cable 16.
  • FIG. 3 also illustrates a plastic electrical connector thereon is an integrally formed pin contact 50 rather than a socket contact.
  • This termination member may be utilized in the same manner as the termination members illustrated in FIGS. 4 and 5, and would be utilized with an electrical connector housing containing socket contacts.
  • a methodof terminating a flat cable having a plurality of parallel, spaced conductive tracks thereon coveredwith insulation comprising the steps of:
  • a termination device comprising a deformable flat metallic sheet bent to a U-shaped configuration providing a pair of flat spaced legs, said legs having generally parallel rows of barbs thereon, said rows being spaced apart a distance corresponding to the spacing of said conductive tracks; inserting the end of said cable between said legs with said tracks aligned with said rows of barbs; crimping said legs onto said cable end so that said barbs pierce said insulation and contact said conductive tracks; and removing the metal of said termination device between said tracks to electrically isolate said tracks from each other.
  • An electrical connection arrangement comprising:
  • each of said Z-shaped metallic members providing three flat, generally parallel legs;
  • one end of one of said flat cables being positioned with its conductive tracks located between two adjacent legs of each of said metallic members;
  • one end of the other of said flat cables being positioned with its conductive tracks located between the third leg of each said metallic member and the next adjacent leg thereto;
  • said ends of said flat cables are devoid of insulation between said metallic members.
  • a method of connecting the ends of a pair of flat cables each having a plurality of parallel, spaced conductive tracks thereon covered with insulation comprising the steps of:
  • a connecting device comprising a deformable flat metallic sheet bent to a Z-shap'ed configuration providing three flat spaced generally parallel legs, said legs having generally parallel rows 'of barbs thereon, said rows being spaced apart a distance corresponding to the spacing of said conductive tracks;
