Abstract
An electrical terminal connection system includes first and second terminals that are interlocked by placing the first terminal on top of the second terminal and rotating the first terminal. The first terminal has a planar ring section with an outer perimeter and a centrally located aperture. The perimeter has cut-out portions. Inclined spring elements extend from the ring section near the outer perimeter. The second terminal includes a semi-circular part with an outer periphery and a centrally located collar. Curved walls extend perpendicularly from the outer periphery. The walls have ledges projecting over the semi-circular part. Aligning the cut-out portions of the first terminal with the curved walls and ledges of the second terminal enables the planar ring section of the first terminal to be placed on the semi-circular part of the second terminal, with the aperture receiving the collar. Rotating or twisting the first terminal causes the spring elements to contact and slide under the ledges. Simultaneously, a catch extending from the second terminal moves behind a locking edge formed in one of the cut-out portions of the first terminal as a side of the first terminal abuts agai…
