Definitions

  • This invention relates to the joining of electrical conductors in the 19- to 26-gauge range; and specifically concerns the making of solderless metal-to-metal insulated joints in such conductors.
  • the connector consists of a shell, a piercing-type insert, a leaf spring therebetween, and a plastic film advantageously bonded to the shell. Connections are effected by a portable tool comprising a die with a main-slot wire guide for all splice types. In the splicing process, the edge of the shell severs conductors which are led up through a branching slot.
  • the spring force on the insert maintains long term contact of the piercing tangs with the conductors.
  • the insert advantageously is comprised of a spring temper phosphor bronze material which allows the formation of strong tangs. Convolutions at each end of the insert provide mechanical gripping of the conductors to prevent pullout.
  • the spring is compressed during the crimping, thus applying for the life of the connection a positive compressive force to the insert.
  • the shell protects the insert from external disturbance, while transmitting forces between the insert and the spring. A fairly substantial force is generated by the spring in conjunction with an annealed brass shell, which constitutes a preferred inventive embodiment.
  • connections may be made between two or three conductors ranging in gauge from 19 to 26.
  • FIG. 4a is a top view of the crimping die jaws of FIG. 4;
  • FIG. 4b is a frontal perspective view of the die jaws depicted in FIG. 4;
  • FIGS. 5 through 17 are various side sectional views of the connector of FIG. 2 showing connector bending and crimping sequences occuring in the crimping die;
  • FIG. 18 is a top perspective view of an alternate embodiment of the body and spring members of FIG. 1;
  • FIG. 19 is a top perspective view of an alternate embodiment of the spring and insert members of FIG. I.
  • FIGS. 20 through 26 are schematic diagrams of various wire connections that may be made by the present invention.
  • FIG. 1 shows the components of a connector 5 in exploded view prior to their being crimped.
  • the shell, designated 10 is an elongated generally J-shaped member made of annealed brass, by a process of stamping.
  • the walls l1, 12 of shell 10 each include perforations 13, I4 and 15, 16 respectively, symmetrically placed inwardly of the wall ends.
  • On each of the two ends ofthe walls 11, 12 are inwardly extending tabs 17, 18 and 19, 20 respectively.
  • the wall 11 is taller than wall 12, and includes one or more edge extensions such as extensions 2
  • the spring member designated 30 advantageously comprises an elongated strip made of spring temper phosphor bronze and comprising relatively flat end portions 31, 32 and a central outwardly protruding bow portion 33.
  • Spring 30 also includes along its sides. arms 34, 35, which locate in the perforations 13, 14 respectively, of shell 10; and arms 36, 37 which locate in the perforations l3, 14 respectively, of shell 10; and arms 36, 37 which locate in the perforations I5, 16 of shell 10.
  • insert 40 is likewise made from spring temper phosphor bronze by the process of stamping. Viewed edge-on, insert 40 is .I-shaped and consists of a floor 41, a major wall 42, and opposite thereto minor wall 43. Insert 40 is substantially coextensive in length with shell 10. Wall 42 includes cutout portions 44, 45 at its ends, the cutouts 44, 45 engaging tabs 18, 17 respectively ofwall ll of shell 10, as seen in FIG. 2.
  • insert 40 consists of a field 46 inwardly protruding tangs centrally located in floor 41; and a field 47 of inwardly protruding tangs centrally located in the wall 42.
  • the tangs of the tang fields 46, 47 are advantageously punched out, with spacings to ensure that any conductor in the range 19 to 26 gauge is contacted.
  • Outwardly of the tang field 46, on either side of floor 41, are formed a series of transverse ribs 48, 49, 50 at one end and 51, 52, 53 at the other end. Each two adjacent such ribs are provided with spaces between them.
  • Wall 42 of insert 40 includes inwardly extending ribs 54,55, 56 at one end and 57, 58, 59 at the other end.
  • the ribs 54-59 likewise are transverse of wall 42 and advantageously commence at the edge 60 of wall 42, ending short of the bend line 61 between wall 42 and floor 41.
  • the region between the end of each rib 54-59 and the bend line 61 is provided with raised nipples 62-67, respectively situated opposite the ends of ribs 54-59.
  • the nipples 62-67 prevent wires from escaping from the tangs, and importantly also promote formation of a second bend line 61a to achieve parallelism between the floor 41 and the wall 42 after forming, as seen in FIG. 11.
  • the floor ribs 48-50 and the wall ribs 54-56 are staggered in spacing so that when the insert 40 is folded during the effecting of a connection, these ribs shall interleave.
  • the ribs 51-53 are spaced with respect to the ribs 57-59 so that interleaving shall occur when the insert 40 is folded.
  • the edge of major wall 42 of insert 40 is provided with three cutouts 68, 69, 70; and the minor wall 43 of insert 40 is provided with cutouts 71, 72, 73.
  • the edge extensions 21, 22, 23 of the wall 11 of shell 10 are caused to engage the insert cutouts 68-70 and also the insert cutouts 71, 72, 73. This further locks the insert with respect to the shell.
  • a plastic film designated 80 is bonded to the shell 10 in the manner shown in FIG. 2, to provide electrical insulation for the metallic parts of the assembly.
  • Plastic film 80 is generally .I-shaped to conform to the shape of shell 10, but wider than shell 10, and its wall 82 is longer than the corresponding wall 12 of shell 10 as shown in FIG. 2.
  • Plastic film 80 advantageously is corrugated longitudinally to provide both a degree of rigidity and extensibility in the transverse direction.
  • the material from which film 80 is made is a polyester having good mechanical and electric properties as well as environmental stability.
  • the bonding agent is, for example, a polyester adhesive having long term adherence under severe environmental conditions.
  • FIG. 18 An alternate embodiment ofthe shell 10 is shown in FIG. 18 in which the spring member is formed directly thereinto.
  • FIG. 18 certain numerals used in FIG. 1 denote parts which correspond identically to those shown for the shell 10 in FIG. I.
  • This alternate shell of FIG. 18, designated shell 10a differs from that shown in FIG. 1 principally in that there is formed directly into the base 26 of shell 10a an inwardly extending bow 33a which corresponds in structure and function to the bow 33 of spring 30.
  • the shell 10a combines the structure and function ofshell 10 with the spring 30 shown in FIG. 1.
  • FIG. 19 shows an alternate embodiment of the insert 40, designated insert 40a.
  • insert 40a certain numerals denote parts of insert 400 which are identical to those designated with like numerals for insert 40 in FIG. I.
  • the difference between the inserts 40 and 40a is that the central tang fields 46, 47 as well as the ribs 54-59 and 48-53 are replaced by a series of bowed or raised areas which have interleaving transverse serrated edges, these being designated serrated edges 90 through 97 located in wall 42, and 98 through 105 located in floor 41.
  • the advantage of insert 40a is that a spring such as spring 30 is not necessary as resilience is inherent in this bow shape; and that furthermore, the transverse serrated edges 90 through 97 can be more precisely controlled as to shape and sharpness. The latter permits a more precise control of insulation penetration and contact with the underlying conductor.
  • FIGS. 4, 4a, and 4b depict a crimping die designated 110 and consisting of a jaw 111 and a die 112. .law 111 is movable in the directions shown by arrow 113.
  • the jaw 111 and die 112 advantageously are mounted on opposing arms of either a handtool or a bench tool (neither shown).
