Definitions

  • This invention relates to a connector clip, and more particularly, to a connector clip to be connected to magnet wire.
  • the ferrule normally has two sections: a crimp section adjacent the receptacle that is to clamp upon the wire and make electrical connection with respect to it, and a clamp for the insulation surrounding the wire.
  • These clips may be mounted in a cluster assembly wherein three equiangularly-spaced clips are mounted in a cluster block, the clips being connected directly to the magnet wire from a motor used in a hermetically-sealed compressor.
  • An objective of the present invention has been to provide a clip having a crimp section that makes good electrical contact with the magnet wire when it is clamped onto the wire in a conventional way.
  • the objective of the invention is attained by providing, on the wire-engaging surface of the crimp section, a series of transverse serrations or alternating ribs and grooves.
  • the ribs penetrate the insulation when the crimp section is applied to a magnet wire and thus provide electrical contact as well as a good grip on the wire.
  • burrs are inevitably left on the corners of the ribs. Normally, such burrs would be cleaned away but, in accordance with the present invention, it has been found that those burrs improve the insulation stripping function of the ribs to provide good electrical contact.
  • at least the crimp section of the clip is plated with tin to a thickness in the range of 0.0001 inch - 0.0003 inch. It has been found that this post-plating, although an expensive operation, has been necessary in order to obtain a satisfactorily consistent millivolt drop across the connection.
  • the plating not only protects against the oxidation of the phosphor bronze from which the clips are formed, but additionally assists in the formation of a mechanical bond which is free of oxygen and permits a tin migration to form a chemical bond as well as the mechanical bond.
  • Fig. 4 The operation in clamping about a wire is illustrated in Fig. 4.
  • the ribs in penetrating into the wire during the crimping operation, bite off a chunk of insulation as indicated at 30 in Fig. 4, the insulation being carried by the top 31 of the rib below the original surface of the wire.
  • the shearing away of that insulation causes the wire to be bared along the sides of the rib and to create an intimate electrical contact at the interface between the rib and wire indicated at 32.
  • the penetration is deep in order to provide the good electrical contact. That depth of penetration, however, tends to weaken the wire.
  • the grooves are shallow so that the penetration is not as deep. While there is a sacrifice of electrical contact, there is a gain in the strength of the wire so that the wire will always be held tightly gripped by the clip.
