Definitions

  • An electrical connector is provided with tapered surface means along the internal surface of a dielectric sleeve and at the entrance to a ferrule defining funnel means to guide a conductive portion of an insulated conductor means within the ferrule.
  • Groove means are provided in an exterior surface of the dielectric member about a central portion of the ferrule to define crimplocating means for locating the crimping dies of a crimping tool in proper relationship along the ferrule so that an effective crimp can be made.
  • This invention relates to electrical connectors and more particularly to electrical connectors having guide and crimp-locating means and a method of making same.
  • Electrical connectors are used in large quantities for terminating electrical Wires and for making electrical connections.
  • One drawback of present day electrical connectors is that no guide means is provided to eifectively guide the conductive portions of electrical wire means into crimping sections of the electrical terminals.
  • Another drawback is that no crimp-locating means is provided on the electrical connectors to properly locate crimping-die means relative to the crimping sections.
  • An object of the invention is to provide an electrical connector having guide means to guide a conductive position of wire means into a crimping section of the electrical connector.
  • Another object of the invention is the provision of crimp-locating means on an electrical connector to properly position crimping-die means relative to a crimping section of the electrical connector.
  • a further object of the invention is to provide an electrical connector with. guide means to guide a con ductive portion of Wire means into a crimping section of the electrical connector and crimp-locating means on the electrical terminal to properly position crimping-die means relative to the crimping section of the electrical connector.
  • An additional object of the invention is the provision of an electrical connector having an insulation support section to accommodate insulation of wire means to be crimped in the crimping section.
  • a still further object of the invention is the provision of a method of forming guide and crimp-locating means on an electrical connector.

  • Lug 3 has an opening 5 therein so that the electrical connector can be connected to a conductive member thereby in accordance with conventional electrical connection techniques.
  • Lug 3 can however take any suitable form to effect an electrical connection with another electrical condutive member.
  • the ferrule 4 is a sleeve and defines a crimping section in which a conductive portion of an electrical wire means is crimped.
  • Serrations 6 are formed on the interior surface of ferrule 4 in order to increase the tensile between ferrule 4 and the conductive portion of the electrical Wire means as well as to score the conductive portion to break down the oxide coating on the conductive portion to increase electric conductivity.
  • the entrance of ferrule 4 has a beveled surface 7.
  • Metallic part 1 is susceptible to mass production by automatic machinery and is conveniently formed by shaping a sheet metal blank or strip of a suitable electrically-conductice metal such as brass, bronze, or the like in successive forming steps.

  • Dielectric part 2 is a suitable plastic material such as, for example, polyvinyl chloride, nylon or the like which is susceptible to cold-forming techniques.
  • Dielectric part 2 is a sleeve and includes a brst section 8 and a second section 9.

  • Annular projection 13 also serves to limit the movement of ferrule 4 within first section 8 of dielectric part 2 so that circumferential groove 10 is properly positioned relative to ferrule 4.
  • Electrical connector ECa illustrated in FIGS. 3 and 4 is similar to electrical connector EC of FIGS. 1 and 2 except that second section 9a of dielectric part 2a of electrical connector ECa has a substantially constant outside diameter therealong. It is to be noted however that first portion 11a of second section 9a includes an inner surface of frusto-conical configuration which merges with beveled surface 7a of ferrule 4a thereby defining a substantially constant tapered surface between first portion 11:: of dielectric part 2a and the entrance to ferrule 4a of metallic part 1a to provide the funnel means to permit the ready insertion of the conductive poriton of the electrical wire means into ferrule 4w.
  • ferrule 4b illustrated in FIGS. 5 and 6 is directed to an electrical connector to splice the ends of electrical Wire means together.
  • ferrule 4b is similar to ferrules 4 and 4a except that ferrule 4b is made as a ferrule having two ferrule sections in which respective ends of conductive portions of electrical wire means are crimped.

  • mold parts 15 and 16 of mold M are spaced from each other and rams 21 and 28 are positioned so that a tubular member 34 of suitable plastic material of proper length is placed within open mold M onto first ram member 22. Mold parts 15 and 16 are brought into engagement to form mold M and are held in a closed position by conventional means. Rams 21 and 28 are moved toward each other by conventional driving means so that reduced section 26 snugly and tightly mates with straight surfaces 20' and stop surface 27 engages mold parts -15 and 16 thereby limiting the movement of ram 21 within mold M but continuous pressure is applied to ram 21 to maintain it in this position.
  • Ram 28 continues to move within mold M with tapered section 30 engaging tubular member 34 thereby causing tubular member 34 to be increased in diameter as ram 28 moves inwardly.
  • Ram 28 continues to move within mold M until cylindrical section 29 bottoms in blind hole 25, pushing surface 32 pushes against an end of tubular member 34 and stop surface 33 engages mold parts 15 and 16.
  • the section of ram 28 between pushing surface 32 and stop surface 33 fits snugly within straight surfaces 20'.
  • tubular member 34 moves into engagement with tapered surfaces 19 and straight surfaces 20 by tapered section 30 and straight section 31 to form first portion 11 and second portion 12 of dielectric part 2.

  • ferrule 4 of metallic part 1 is inserted in first section 8 of dielectric part 2 to form electrical connector EC of FIGS. 1 and 2.
  • the inside diameter of first section 8 is such so that ferrule 4 is held therein by friction therebetween.
  • the completed electrical connector is now ready to be crimped onto an electrical wire means with the guide means effectively guiding the bared conductive portion of an electrical wire means into ferrule 4 and the crimp-locating means properly locating crimping-die means to crimp ferrule 4 onto the conductive portion of the electrical wire means.
  • Second section 9 of dielectric part 2 may be crimped onto the insulation of the electrical wire means to provide strain relief.
  • the mold to form dielectric part 2a for electrical connector ECa of FIGS. 3 and 4 is the same as the mold to form dielectric part 2 except that tapered surfaces 19 and straight surfaces 20 have the same diameter.
  • FIG. 9 illustrates mold Ma to form dielectric part 2b of FIGS. 5 and 6.
  • Mold Ma includes mold parts 35 and 36.
  • Each of mold parts 35 and 36 includes on the interior surface spaced projections 37, beveled surfaces 38 on each side of spaced projections 37 and straight surfaces 39.
  • Spaced projections 37, beveled surfaces 38 and straight surfaces 39 are semi-circular in cross section.
  • Compound rams 40 are insertable within mold Ma and include first ram members 41 and second ram members 42.
  • Ram members 41 are snugly disposed in openings 43 of ram members 42 so that ram members 41 are movable relative to ram members 42 and relative to each other.
  • Ram members 41 include rounded-nose sections 44, tapered sections 45 and cylindrical sections 46.
  • Ram members 42 include reduced sections 47 and stop surfaces 48.
  • mold parts 35 and 36 are spaced from each other and rams 40 are positioned so that a tubular member 49 of suitable dielectric material and of proper length with ferrule 4b therein can be placed within mold Ma.
  • Mold parts 35 and 36 are closed and held by conventional means; rams 40 are simultaneously moved within the mold by conventional driving means.
  • ram members 41 position ferrule 4b so that the ferrtfle sections thereof are properly positioned relative to projections 37 by means of roundednose sections 44 being positioned within the ferrule sections of ferrule 4b and tapered sections 45 engaging the beveled surfaces of the ferrule sections.
  • Reduced sections 47 fit snugly in straight surfaces 39 and the inner ends of the reduced sections of ram members 42 engage respective ends of tubular members 49 as rams 40 are being driven inwardly thereby applying pressure to the tubular member toward the center thereof causing the material of tubular member 49 to flow into beveled surfaces 38 to form the crimp-locating means and to flow into the areas between the ends of ferrule 4b and tapered sections 45 to form annular projections 13b and tapered surfaces so that the inner surface of tubular member 49 is tapered on each side of the ferrule and these tapered surfaces merge with the beveled surfaces of ferrule 4b which form substantially constant tapered surfaces therebetween to define the guide means.
  • Rams 40 are moved out of mold Ma and mold parts 35 and 36 are moved apart so that electrical connector ECb can be removed from the mold.
  • tubular member 49 into dielectric part 2b by mold Ma and rams 40 forms a completed connector with ferrule 4b locked into position within dielectric part 2b by annular projections 13b.
  • a small amount of material of tubular member 49 may flow into spaced indents 14 but this will not impair the formation of the crimp locating means by projections 37 and beveled surfaces 38.
  • spaced projections 37 may be a solid projection thereby eliminating inner beveled surfaces 38 so that the groove formed by the single projection will be substantially constant in diameter throughout and the flow of material into indents 14 will then occur.
  • a continuous groove along substantially the entire length of ferrule 4b will still perform the function of locating crimping die means relative to the ferrule sections of ferrule 4b because each side of the groove will properly locate the crimping die means relative to the crimping sections of ferrule 4b.
  • Ribs may be formed partially around the first section of the dielectric part instead of being formed entirely therearound as preferred.
  • dielectric part 2a of FIGS. 3 and 4 and 2b of FIGS. 5, 6, and 9 may be a two-step operation instead of a one-step operation. This is accomplished by placing within the tubular members of dielectric material to form dielectric parts 2a and 2b a rod of constant diameter within the tubular members and ram members would engage the ends of the tubular members to first form the crimp-locating means. The rods would be replaced by suitable ram members to then form the guide means Within the tubular member in the case of dielectric 6 part 2a, and, in the case of dielectric part 2"b, ferrule 4b and ram members 41 would be used in the second operation to form annular projections 13b and the guide means.
  • second section 9a can be subjected to controlled expansion to expand this section to any desired diameter within the limits of expansion of the material. This would also be true with respect to dielectric part Zb of FIGS. 5 and 6.
