ABSTRACT:
A solderless connector for joining the flexible electrical moving leads connecting the voice coil of a loudspeaker to the electrical input terminals located on the loudspeaker frame. The connector supplies electrical continuity between the flexible conductor and the terminal, and mechanically secures the flexible conductor without the need for solder or other mechanical means, thereby improving efficiency of assembly and improving quality by eliminating problems attributable to poor workmanship in soldering operations. These movable leads are known as pigtails, and their length is adjusted to insure long life and to eliminate distortion. A pigtail that is too short will limit cone excursion by becoming taut and introduce distortion into the acoustical output. A short pigtail will also result in early failure of the loudspeaker due to the excessive stress. A pigtail that is too long will also introduce distortion due to the generation of spurious noise. The method of ensuring correct pigtail length employs a dressing fixture.
