  • Such double ended tubular connecting devices can be used for example, on a panel-like member for connecting wires which are on opposite sides of the panel to each other and can be used with a suitable insulating means as a dead end connector.
  • the invention is also directed to the achievement of an improved strain relief for tubular conductor-in-slot connecting devices which retains an inserted conductor against movement laterally (rather than axially) out of the slot of the connecting device.
  • This strain relief can be used in conventional single ended tubular connecting devices of the type under consideration as well as double ended devices.
  • a further object is to provide a double ended conductorin-slot connecting device.
  • a still further object is to provide an improved strain relief for a conductor-inslot connecting device.

  • FIG. 9 is a view illustrating the principle of the strain relief means which is provided on the connecting device of FIG. 7.
  • FIG. 1 shows a connecting means 2 for connecting the ends of wires 4 to each other, this connecting means incorporating a double ended tubular conductor-in-slot connecting device in accordance with the invention.
  • the connecting means 2 comprises a double ended formed tubular member 6 of suitable insulating conductive sheet metal, a tubular insulating sleeve 20, and two end caps 29 which are threaded onto the insulating member 20.
  • the conductive tubular member 6 is cylindrical throughout the major portion of its length and has an axially extending open seam 8 which serves as a conductor receiving slot.
  • the tubular body is transversely sheared as shown at 10 midway between its ends and partially around its circumference.
  • the shear lines 10 extend to punched holes 12 which serve to prevent propagation of the cracks from the ends of the shear lines.
  • Openings 14 are provided at each end of the tubular member 6 for the reception of the wires as will be described below and the edges of these openings extend convergently to the ends 16 of the slots 8.
  • a pair of radially extending ears 18 are formed on each side of the openings 14 to retain the metallic tubular member 6 in the insulating tubular member 20 as shown in FIG. 6.
  • the insulating member 20 has an open seam or gap 22 which is somewhat wider than the seam 8 and has external threads 24 on its surface which extend partially inwardly from each end to outwardly facing stop shoulders 27.
  • the edges of the seam or gap 22 are notched at each end of the insulating member as shown .at 26, these notches being adapted to receive the previously described ears 18.
  • end caps or end covers 29 are in the form of cuplike cylindrical members having internal threads 28 which engage with the threads 24 and have axially extending centrally located cylindrical ram or wire stuffer 30 members integral therewith.
  • the conductive tubular member 6 may be formed of any suitable conductive metal such as phosphorbronze, beryllium copper etc. Good results are obtained with a No. 4 hard cartridge brass having a thickness of about 0.012 inches and the plastic parts 20, 29 may be molded of any suitable plastic material which is relatively firm and rigid in thick sections but which should have some flexibility.
  • the conductive tubular member 6 is assembled to the insulating sleeve member 20 by merely moving these two members laterally towards each other from the positions shown in FIG. 2.
  • the conductive member can be forced through the gap 22 of the insulating member if the insulating member is capable of flexing to a slight degree and after assembly, the ears 18 will be seated in the recesses 26 as shown in FIG. 6 to prevent rotation of either member with respect to the other.
  • the cap members are assembled to the insulating sleeve and the wires are inserted into the open ings 14 as shown in FIG. 3.
  • the cap members are then merely moved inwardly and towards each other until the faces 32 of the cap members are against the shoulders 27.
  • Such movement of the cap members 29 force the wires into the slot 8 so that the edges of the slot penetrate the insulation of the wires and establish electrical contact with the conducting core thereof.
  • the cap or cover members 29 and the insulating sleeve 20 are advantageously formed of a material which has some flexibility and depending upon the degree of flexibility on this material, the cap members may be simply passed inwardly from the posi' tion of FIG. 3 to the positions of FIG. 4 and the teeth will flex while they move over each other. The cap members can be removed by unthreading and the device can be reused if desired.
  • Suitable materials for the plastic parts are poly carbonate and nylon, the latter material being glass-filled to the extent necessary to achieve the desired combination of hardness or firmness and flexibility FIGS.
  • FIGS. 7-9 show an alternative form of double ending connecting device 34 which is adapted to be mounted in a panel-like member 34 for connecting wires 38 on the upper side of the panel to wires 40 on the lower side.
  • the connecting device 36 comprises a formed tubular member 42 having an axially extending seam 44 which serves as a conductor receiving slot. Mid-way between its ends, the tubular member is partially transversely sheared as shown at 46, the shear lines extending to punched holes 48 for reasons previously discussed. Opposed spaced apart tangs 50 are struck from the tubular member on each side of the shear line 46 for retaining the member in the panel-like member.
  • the connecting device is mounted in the panel by merely inserting it into a circular hole in the panel and the tangs 50 will bear against the opposite sides of the panel as shown.
  • FIGS. 79 has an improved strain relief at each end to impede or prevent movement of the wires laterally of their axes from the slot.
  • This strain relief means is provided adjacent to the con-.
  • ductor receiving openings 52 at the ends of the connecting device is formed by shearing the tubular member adjacent to the openings 52 transversely as shown at 56, the shear lines extending partially around the circumference to punched holes 58.
  • the portions 60 of the tubular member which lie between the shear lines 56 and the edges 59 of the openings are formed inwardly towards the axis of the tubular member so that the retaining portion 62 of the slot 44 is relatively more narrow than the central conductor receiving portion of the slot.
  • the axial seam thus has a retaining portion of restricted width which extends from a first location (the intersection of the edges 59 and the axially extending edges of the portion 62 of the seam) to a second location defined by the intersection of the shear lines 56 with the seam.
  • the first and second locations define an entrance portion, a contact slot portion, and a retaining portion of the seam.
  • the entrance portion is bounded by the end of the tubular member and the first location and is coincident with the opening edges 59.
  • the retaining portion 62 is between the first and second locations.
  • the second location defines the outermost extent of the contact or conductor receiving slot portion, 44.
  • the slot may, in fact, be completely closed although there will usually be a narrow gap at 62 because of spring back effects in the metal.
  • FIG. 9 illustrates the principle of this strain relief feature and shows a wire located against the edges 59 of the opening 52, the position it would occupy. immediately prior to being moved into the central portion 44 of the slot.
  • a downward force F (which represents the insertion forces) is applied to the wire in FIG. 9, it will be transmitted to the tubular member as two components each of which has a magnitude of F /2 and which is directed substantially normally of the portion of the edges 59 against which the wire bears.
  • Each force F /2 is a resultant of a vertical component and a horizontal component as indicated and the horizonal component force will tend to flex the associated portion 60 in one direction or another (outwardly or inwardly) so that the slot section 62 will be opened. Whilethe wire is being moved through the section 62 of the slot, there will ordinarily be some penetration of the insulation and this section of the slot will not be opened to a width which is equal to the diameter of the insulation of the wire.
  • a strain relief means as described above can beused in single ended connecting devices of the type shown in application Ser. No. 347,956 and the principle is equally applicable and can be used with connecting devices of the type shown in application Ser. No. 405,970 now US. Pat. No. 3,845,455. In the latter case, the strain relief can be provided on the strain relief slot rather than the electrical contact slot of the connecting device.
  • While the disclosed embodiment has a single shear line on each side of the open seam to providetwo separate spring systems, it will be apparent that an additional number of shears can be provided to form an additional number of spring systems, for example, two separate spring systems can be provided on each side of the middle of the connecting device so that a total of four wires can be electrically connected to each other.
  • Double-ended metallic connecting devices in accordance with the invention can be used under circum stances other than those disclosed above where it isexpedient to insert the wires from opposite ends of the connecting device rather than from only one end.
  • the individual tubular connecting device would ordinarily have a contact means for disengageably contacting a complementary contact terminal in a complementary multi-contact electrical connector.
  • a conductor-in-slot electrical connecting device comprising:
  • a formed metallic tubular member of conductive sheet metal said member having an axially extending open seam extending from one end thereof to the other end thereof, said seam serving as a conductor-receiving slot and having edges which are adapted to engage a conductor inserted into said said member being partially transversely severed intermediate the ends thereof from said edges partially around the circumference of said member whereby said member is divided into two separate spring systems, for reception of at least two conductors,
  • each of said conductor receiving means comprising an opening in the wall of said member adjacent to said ends, each of said openings intersecting said edges of said conductor-receiving slot a tubular insulating member in surrounding relationship to said metallic member, said insulating memher having an axially extending open seam which is in alignment with said open seam of said metallic member, and
  • insulating cover means each end of said tubular insulating member, said cover means being movable relatively towards each other on said tubular insulating member whereby,
  • a conductor-in-slot electrical connecting device comprising:
  • a formed metallic tubular member of conductive sheet metal said member having an axially extending open seam extending from one end thereof to the other end thereof,
  • said member being partially transversely severed intermediate the ends thereof from the edges of said seam partially around the circumference of said member by severance lines which are in alignment on opposite sides of said seam, whereby said member is divided into two separate spring systems forreception of at least two conductors,
  • each of said conductor receiving means comprising an opening in the wall of said member adjacent to said ends;
  • an insulating cover means at each end of said tubular insulating member, said cover means being movable relatively towards each other, whereby upon locating a conductor in each of said openings with the axis of said conductors extending laterally of the axis of said member, and upon movement of said cover means towards each other, said conductors are moved by said cover means laterally of their axes towards said severance lines, and into said contact slot portions whereby said edges engage, and establish electrical contact with said conductors.
  • said cover means at each end having internal ram means movable along the axis of said tubular member and inside said tubular member, so that when said cover means are moved relatively towards each other said ram means push the portions of said conductors inside said tubular member towards each other.
