Definitions
- This invention relates to electrical connectors of the type which are adapted to be crimped onto one or more conductors, and more particularly to such an electrical connector which is especially suitable for crimping onto insulated, coated or dirty conductors.
- wires which are commonly used for making electrical connections have a layer of tough, elastic, insulating coating such as Formvar or Formex (polyv nyl formal or polyvinyl acetal).
- bare electrical wires often become dirty, or develop corrosion layers, such as oxides or sulphides, which effectively increase the contact resistance or even insulate the conductor.
- it is desired to make connection to conductors having such external layers or films it is first necessary to pierce or scrape away the insulating coating in some manner before an electrical contact of low ohmic resistancecan be achieved with the current-carrying portion of the wire.
- solderl'e ss connectors having relatively sharp teeth or ridges which are designed to be forced through a covering of insulation by the application of compressive force.
- tough coatings such as Formvar are nearly impenetrable to connectors of this type.
- an electrical connector of the type which is adapted to-be crimped or pressure-forged onto one or more wires, which is capable of partially shearing the wires during the crimping operation, and of jamming the sheared surfacesiri a sticking taper so as to create a permanent and stableelectrical contact with the conducting portion of the wires.
- Figure 1 is a cutaway plan view of a connector embodying the present invention and crimped onto a stranded conductor
- Figure 2 is an enlarged fragmentary cross-section view of a grooved inner surface of the connector of Figure 1
- Figure 3 is a plan of the connector in flat condition before rolling up to ferrule form
- Figure 4 is an enlarged cross-section view of a modified groove'shown with its coining die. 7
- a terminal connector generally indicated at 2 and having a ferrule portion 4 is shown crimped 2,800,638 Patented July 23, 1957 onto a stranded wire 6 of an insulated cable 8.
- the ring tongue 10 (shown in Figure 3) of the connector 2 is representative of the various contact portions adapted for attachment to another conductor, a binding post or other terminal device (not shown).
- Each of the wires 6 may be coated with oxide, sulphide, oil or wax or insulating material from the insulation coating 9.
- FIG. 1 shows a number of grooves 12, the edges of which form an abrupt angle adapted to shear through layers on the peripheral strands of the wires 6 and into the metal of the strands to make contact with the current-carrying portions of these strands during a crimping operation wherein the ferrule portion 4 is forced inwardly against the conductor under sufiiciently heavy pressure to deform the metals.
- the sides of the grooves are sloped with an angle of a sticking taper for the metals concerned, so that when, during such a crimping operation the portions of the wire 6 adjacent the grooves 12 are sheared and driven into the grooves, as indicated in the drawings at 6A, the sheared surfaces are jammed in the taper with such pressure that the surfaces are tightly. held and are tight against corrosion.
- the crimping pressure will advantageously force the wire to bottom against the deepest surfaces of the grooves and coin itself into every crevice thereof. Because of this bottoming effect, the shearing action is prevented from seriously weakening the wire after piercing the layer of insulation; any additional crimping after the wires reach bottom results only in coining of the conductor material.
- the dimensions of the grooves may vary Within substantial ranges while still allowing the grooves 12 to be effective in shearing into and permanently gripping the wire 6.
- the width 11 of the groove 12 between the shear edges is particularly important in achieving good shearing action.
- the depth 13 of the grooves 12 and the breadth of the lands 15 between the grooves are also important, as described hereinafter.
- connection is a function both of the crimping pressure and the width of the groove.
- the gap size between the shearing edges of the grooves will ordinarily fall within the range of approximately 0.010 to 0.020 inch.
- the width dimension of the grooves should approximate the strand diameter of the conductor to about 0.02 inch. With solid wires the width of the grooves may be relatively less than for stranded wire, but in general it is the strand diameter rather than overall wire gauge which controls the dimensions of the groove.
- Such a dimensional range additionally, will allow a relatively large number of grooves to be cut into the inner face of the usual types of solderless connector ferrules, which is an advantage not only because of the multiplication of area of fresh metal contact, but because it assures contact with more strands in a multistrand wire, as the spiral lay of a wire brings different strands into position to engage the shear edges in different areas.
- the conductor material which is driven into the grooves by the crimping pressure takes on a compressive stress, and thus by its own elasticity maintains a tightly pressed contact against the side walls of the groove. That is, the conductor material flowing into the groove encounters .a continually-decreasing cross sectional area, so that this material is compressed as it is forced into a region of diminishing volume.
- the amount of compressive stress so built up, and more especially the tendency of the sheared portion ofthe wire to hold tightly to the sides of the groove is determined partly by the slope given to the groove walls. To minimize the possibility of corrosion it is advantageous to provide for maximum compressive stress on the conductor portion between the sloping sides of the grooves, while keeping the angle small enough to assure a selfholding taper engagement.
- a range of optimum taper angles according to this invention, which satisfies these requirements is from to 60.
- This angle should be smaller for tougher layers surrounding the conductor, and may be larger with soft or frangible coats.
- a very good taper angle is about 5".
- a taper angle as large as 50 has been found satisfactory.
- the depth of the groove should be suflicient to assure that any insulating layer will be sheared through before the sheared portions of the wires 6 bottom in and fill the grooves. This filling, which stops the shearing movement, should occur shortly after completion of shearing through of the insulation layer or coating, and before any of the wires 6 have been sheared to the extent of probable fracture.
- the optimum depth is roughly one half the diameter of the individual strands of the conductors.
- a groove depth of about 0.006 inch has been found to be quite advantageous, whereas in a terminal designed to be crimped onto bared #l2 A.
- W. G. Wires having strand diameters ranging from 0.0159 to 0.0185 inch, a groove depth of about 0.007 to 0.008 inch has been found advantageous in providing the desired connector characteristics outlined hereinabove.
- Terminals having these groove depths are not limited to use only with the particular strand diameters indicated, such terminals being adaptable generally for use with a broader range of conductor sizes while still providing superior results to those accomplished without this invention.
- the range of optimum depth dimensions will, in general, lie between approximately 0.005 and 0.010 inch, with greater depths for enameled wire, and especially poly vinyl methylal enamels.
- the grooves will shear cleanly through tough layers of insulation when the connector is crimped. Furthermore, such grooves will produce a stable electrical connection that is permanently maintained by the endwise compression of the sheared portion of the wire, and will create a solid contact without danger of cutting through the conductors.
- a groove width of about 0.010 inch, a depth of about 0.005 inch, and a taper angle of about 50.
- Figure 3 shows a solderless connector of the type described hereinabove and in which the ferrule-forming portion 4 is in a flattened condition before crimping onto a conductor. Cut transversely across the conductor-contacting surface of the ferrule 4 are a plurality of substantially parallel grooves 12.
- the ear portions 3 and 5 of the ferrule-forming portion 4 are adapted to be folded upwardly (as viewed in the drawing) and wrapped around one or more conductors in telescoping relation thereto, and to be pressed inwardly against such conductors under heavy pressure for forming an intimate, cold-forged connection therewith.
- This folding and crimping operation may be performed by a variety of tools especially adapted for the purpose, such as are well known in the art of solderless connectors.
- the grooves may be formed by machining or stamping, but the tools, whether cutting tools or coining dies, should be as sharp as possible to assure efiicient shear edges.
- Figure 4 I have shown, somewhat exaggerated and enlarged, a relieved coining die to improve the sharpness of the corner which forms the shear edge. I In this draw ing, the coining die 20 is relieved along the base at 22,
- edges 26 of the groove 30 will be initially formed somewhat sharper than the required shear so as to provide a margin of safety.
- my invention is not limited to any particular metal or combination of metals, it is important for best results that the metal in the shearing edges should be harder than the metal of the wire which is to be engaged. Dead soft copper is therefore too soft for most purposes.
- a quarter hard copper or brass 60-70 on Rockwell l5T scale
- the shearing edges may be worked more severely, and therefore be harder, than other parts of the ferrule.
- the shearing edges are first made sharper than the final shear angle, e. g. as shown in Figure 4, and then flattened to give the precise shear angle, the extra working of the metal adjacent the shear edge has a desirable effect.
- Connectors embodying the present invention are advantageous not only for use with stranded conductors but also with solid conductors, even those of relatively large size.
- two or three solid conductors of 0.060 inch diameter each coated with Formvar may be crimped solidly together in the ferrule of a connector of the type hereinabove described, the groove width between the shearing edges being about 0.012 inch wide, the groove depth being about 0.008 inch, and the taper angle of the groove being about 5.
- the groove edges shear cleanly through the Formvar and produce a stable, non-corrosive electrical connection of low ohmic resistance between the conductors. Such a result had not been regarded as possible before the present invention.
- Electrical connectors in accordance with the present invention may advantageously be formed with serrations other than the transverse grooves shown in Figure 3.
- good results may be obtained by serrating the inner face of a ferrule with a number of indentations, the surfaces of each indentation forming a truncated cone or pyramid, the dimensions of which (i. e., width, depth, and slope angle) conform to the pattern set forth hereinabove.
- each of the grooves 12 may be arranged so that it intersects the spiral lay of the wire at right angles, or nearly so, to provide a superior grip on the strands in a direction longitudinal of each strand, and thereby improve the pullout strength of the connector.
- the grooves may be cut in a direction substantially parallel with the axis of the ferrule, and with dimensions varied gradually from a minimum nearer the mouth of the connector to a maximum, more remote so that the wire will be compressed into a sticking taper in a direction radial of the connector ferrule, and will be taper-wedged by any pull on the wire in a direction longitudinal of the ferrule.
