Definitions

  • This invention relates to metal strips of dissimilar electrically conductive alloys having coplanar juxtaposed lateral edges bonded together, and more particularly to such strips of electrically conductive copper based alloys, one only of which contains beryllium.
  • An object of this invention is to provide a strip body of at least one pair of electrically conductive strips having their adjacent edges directly bonded to each other by interpenetration of the metal of the strip, and with the bonded joint free from any extraneous bonding material, and the zone of interpenetration of the alloys of the two strips at their juncture is confined substantially to the plane defined by the original juxtaposed edges of the strip.
  • a specific object is to provide such a strip wherein one strip is a copper based alloy containing beryllium, and the other strip is a dissimilar copper based alloy, such as brass, Phosphor bronze, or nickel-silver, and is free from beryllium.
  • Still another object is to provide an alloy strip wherein the bonded joint is cold rolled and extremely sound, thus preventing fracturing and is substantially free from camber.
  • a specific object is to provide an electrical connector having two portions of different alloys respectively so that one portion has physical qualities rendering it particularly desirable for permanent connection to a conductor and the other part has different physical characteristics rendering it particularly desirable for resilient readily attachable and detachable electrical connections.
  • FIG. 1 is a top plan View of a multi-metal strip of dissimilar alloys embodying the invention, and including a developed view of an electrical connector blank to be made therefrom, as shown by dot and dash lines;
  • FIG. 2 is a cross-sectional view of the strip of FIG. 1
  • FIG. 3 is a front elevation of the completed connector formed from the blank indicated by the dot and dash lines .in FIG. 1;
  • connectors having a tang portion for permanent connection to a conductor and a barrel portion for detachably receiving a conductor prong were, well known and strips for fabricating such connectors were preferably formed from beryllium copper alloys because of the desirable characteristics of such alloys, such as fatigue endurance, resiliency, stability in dimension and shape, and wear resistance.
  • beryllium copper alloy materials presented a problem since the tang portions to which the lead conductors were attached were not capable of being crimped for attachment of the lead conductors when the alloy had the desired characteristics at the barrel portion for resiliently retaining a prong connector. In order to render the connecting portion ductile and crimpable, the tang portion was heat treated.
  • the heat treatment could not be confined to the tang portion alone, particularly where the connector was of a diminutive size useful in miniaturized circuits.
  • the heat treatment deleteriously aifected the properties of the barrel portion, thus reducing the overall efiiciency and quality of the finished product.
  • an elongated strip of beryllium copper alloy and an elongated strip of copper based alloy selected from the group consisting of brass, Phosphor bronze, and nickel-silver have their adjacent lateral edges substantially at a right angle to the faces of the strips and juxtaposed against each other throughout their length and directly bonded together by the interpenetration of the metals to form a narrow bonding and interpenetration zone confined substantially to the plane of the original edges and with a joint substantially free from extraneous metal.
  • the width of the bond in the fusion zone may be approximately 0.005 inch, a width heretofore not obtainable. In fact, the width may range from about 0.003 inch to about 0.030 inch.
  • Both of the strips are electrically conductive, one being ductile and readily deformable for a permanent connection, and the other having greater fatigue endurance, stability in dimension and shape, and wear resistance, and resilience than the one strip, and being desirable for a detachable connection.
  • the two strips are bonded to each other at their lateral edges by arc welding in tungsten inert gas with accurately controlled power input and concurrent accurate relative movement of the arc and strip endwise of the strips to produce a joint due to interpenetration of the alloys of the strips and free from extraneous bonding material, the interpenetration zone .being confined laterally of the strips substantially to the plane of the original edges and the joint being substantially free from camber.
  • the bonded strips are then cold rolled endwise of the joint under pressure which reduces the thickness of the joined strips and the joint, thus pro- ,viding an elongated edge bonded, multi-metal strip of dissimilar alloys.
  • Metal strips according to this invention are particularly .useful for the types of electrical connectors used in fminiaturized circuits including connecting sockets, terminals, prongs, modules, and contacts, where one strip of the metal forms the barrel and the other strip forms the tang.
  • an elongated multi metal edge-bonded composite strip 1 of dissimilar metal alloys One portion 2 preferably is from the class consisting of brass, Phosphor bronze, and nickel-silver, and substantially free from beryllium content.
  • the portion 2 is soft and ductile and possesses excellent crimpability.
  • the other portion 3 is of electrically conductive sheet metal alloy, preferably a copper base alloy containing beryllium.
  • the two portions 2 and 3 are separately formed and rolled alloy strips and their adjacent lateral edges are substantially at a right angle to the face of the strips, as illustrated in the drawing, and are juxtaposed and directly bonded together throughout their length by interpenetration of the alloys of the two strips in a narrow zone of interpenetration, indicated at 4, which is confined substantially to the common plane of the juxtaposed edges and between the planes of the opposite faces of the original strips forming the portions 2 and 3.
  • the bonding is accomplished by arc welding and the resultant joint is free from any extraneous bonding material.
  • the resultant composite strip including the joint, is cold rolled as a unit.
  • the arc welding is performed by tungsten arc welding equipment and techniques while the electrode and instantaneous point of welding are protected by inert gas.
  • the amperage supplied the positions of the electrode, strips, and joint, respectively, are precisely controlled.
  • a precision power unit so controls the electrical phenomena that the amperage does not vary from that selected more than 0.10 percent.
  • Example 1 A coiled strip of brass 0.05 inch in thickness and 250 feet long, and a strip of beryllium copper alloy 0.05 inch in thickness and 250 feet in length, were maintained in intimate edgewise contact while their juxtaposed edges were passing over a stationary tungsten inert gas welding electrode at the rate of 5 to 6 feet per minute at 130 amps. controlled so that the amperage variance was less than 0.1 percent from the setting.
  • Example 2 A 20-foot length of 0.05 inch thickness bronze strip and a 20-foot length of 0.05 inch thickness of beryllium copper alloy strip were joined by the procedure of Example l, with the exception that the strips were passed over the electrode at the rate of 4 feet per minute at an amperage setting of 95.
  • Example 3 Metal strips of nickel-silver and beryllium copper alloy having a 0.05 inch thickness and feet in length, respectively, were joined by the procedure of Example 1, with the exception that the strips were passed over the electrode at the rate of 4 feet per minute at an amperage setting of 100.
  • Example 4 Strips of brass and beryllium copper alloy of 0.05 inch thickness and 250 feet in length, respectively, were joined by the procedure of Example 1, with the exception that the strips were held stationary and the welding electrode was passed over them at the point of edgewise juncture at the rate of 4 and 3 feet per minute at an amperage setting of 95 and 80.
  • the bonded metal strips as a unit, and including the joint were cold rolled to a thickness of 0.032 inch.
  • Various beryllium copper alloys strip may be used for the portion 3 of the composite strip provided they have the desired physical characteristics for the part to be made therefrom.
  • FIG. 3 there is shown an electrical connector 5 made from the composite strip in accordance with this invention.
  • the blank for the connector is indicated at 5a in FIG. 1 and is cut from the strip l by stamping and formed.
  • the resultant connector has a tang 6 which is from the portion 2 of the strip and consequently is sufficiently soft and ductile for crimping around a conductor or like article but strong enough to hold its crimped position.
  • the connector has a barrel 7 which is from the portion 3 of the strip 1 and has adequate strength and resiliency to provide the maximum spring temper desired so that the barrel can resiliently grip a prong inserted therein.
  • the composite strip may be used for forming other articles in which the dual characteristics are found desirable.
  • a metal strip body comprising at least one pair of metal alloy strips, one strip being electrically conductive and readily deformable and capable of remaining in its deformed condition, the other strip being resilient and electrically conductive and having high fatigue endurance, stability in dimension and shape, and high wear resistance, each greater than that of said one strip, and said pair of strips having adjacent edges substantially at a right angle to the faces of the strips and coplanar and against each other throughout their length and directly bonded to each other by interpenetration of the metal alloys of the strips, with the bonded joint essentially free from any extraneous bonding material, said zone of interpenetration of the metal alloys of the two strips at their juncture being confined substantially to the plane defined by the original juxtaposed edges of the strip and being from about 0.003 inch to 0.03 inch in width edgewise of the strips and being confined, flatwise of the strips, between the planes of the faces of the strips.
  • a body according to claim 1 wherein said other strip is a copper-base beryllium containing alloy.
  • both of said strips of the pair are copper base alloys, and one of said strips contains beryllium and the other is free from beryllium.
  • one of said strips is a copper based alloy containing beryllium and the other of said strips is a metal alloy selected from the class consisting of brass, Phosphor bronze, and nickelsilver.
  • An electrical connector having one strip metal portion adapted for connection to a lead conductor by cold permanent deformation of the portion and having a second strip metal portion having a resilient barrel adapted to receive a connector therebetween and engage the connector with yielding pressure, said portions having adjacent juxtaposed strip edges substantially at a right angle to the faces of the strip portions and bonded to each other by the interpenetration of the metal of the portions with a bonded joint essentially free from any extraneous bonding material, the zone of interpenetration of the metals of said portions at the joint being confined substantially to a plane defined by the juxtaposed edges, and being from about 0.003 inch to 0.03 inch in width in the plane of the strips and being confined flatwise of the strips between the 2,417,967 3/1947 Booe.
