Definitions

  • the subject invention relates to an improved electrical terminal and a method of making the same, and in particular terminals having increased contact force added by an additional back-up spring.
  • electrical terminals which include an inner contact portion having opposed contact arms formed by cantilever beams, where a back-up spring or an assist spring is included having back-up spring arms which increase the contact force on the opposed contact arms for increasing the contact pressure to a mating tab terminal.
  • manufacturing is made difficult by the inclusion of the separate outer back-up spring as the back-up spring must be assembled around the inner contact member.
  • the back-up spring is partially assembled and positioned around the inner contact and then finally assembled to the inner contact member.
  • the terminals are generally kept on strip form, while the back-up springs are formed on a separate strip and positioned over the inner contact portions and later formed around the inner contact. This provides a difficult assembly process and furthermore requires the usage of two separate stamping dies to stamp out the separate parts which adds to the total cost of individual components parts.
  • the objects of the invention have been accomplished by providing a method of producing an electrical terminal comprising the steps of laminating two materials together and stamping and forming the laminated combination into an electrical terminal.
  • a prior art electrical terminal is shown at 2 which includes an inner contact member 4 and an outer assist spring 6.
  • the inner contact member is comprised of a forward contact section 8 comprised of opposed cantilever beam spring arms 10 which form opposed contacts for receipt of a tab terminal therebetween.
  • the spring arms 10 extend forwardly from a central section of the terminal 12 at one end, and at the opposite end a wire connecting crimp section 14 extends therefrom. It is also typical to stamp and form the contact member 4 to its complete configuration, but leave the outer back-up spring 6 to a position where the side walls 16 of the back-up spring are slightly open such that the back-up spring 6 can be received over the inner contact member 4.
  • sections 18 can be crimped around the contact arms 10 to retain the back-up spring 6 to the inner contact member 4.
  • the inner contact member 4 is usually comprised of a copper alloy, such as beryllium-copper, whereas the outer back-up spring 6 is comprised of a spring steel such as stainless steel.
  • the terminal shown in Figure 1 is referred to as applicants "Junior Power Timer" where, in order to provide for the electrical conductivity required, the thickness of the base material of beryllium-copper used to stamp and form the inner contact member 4 is 0.32mm in thickness.
  • the conductivity of beryllium-copper alloy is 28 IACS, which is a ratio of the conductivity to pure electrolytic copper, having a base of 100.
  • a new material is formed at 20 which is a lamination of materials 22 and 24, where material 22 is pure electrolytic copper, whereas the material 24 is a stainless steel.
  • an electrical contact can be stamped and formed therefrom to any desired configuration, and as shown in Figure 4, a terminal is shown at 30 having an inner contact portion 34 and a laminar portion at 36 which forms a contact receiving section at 38.
  • Opposed contact portions 40 are formed by a lamination of the reduced thickness portion 28 and by the stainless steel sheet 24.
  • the laminar sheet 20 could be so provided so that the stainless steel outer layer 24 extends along any length of the electrical terminal to provide for various configurations of electrical terminals.
  • the outer laminated layer 24 could extend the entire length of the terminal to include the wire crimp section at 14.
  • the laminar layer 24 only encompasses the opposed contact spring arms 40a and a portion of the central section 42 of the inner contact.
  • FIG. 5 a second embodiment of the invention will be shown which provides a terminal at 120 having similar laminations of copper 122 and stainless steel 124 where contact arms 140 are formed as shown in phantom in Figure 6 and are folded back from a front leading edge 141 such that the assist spring 136 is positioned inside of the contact arms as shown in Figure 5.
  • the laminated material provides a much simpler method of forming the contact, as no assembly of inner spring contact and outer back-up spring is required. Furthermore the entire stamping and forming operations is done with one set of dies, thereby reducing the overall cost of the assembly equipment.
