A connecting sleeve spring is resiliently mounted in a connecting sleeve of an electrical connecting jack. The connecting sleeve spring has a arcuate sinusoid-like side profile, with its two ends curving in a direction opposite the curve of a center contact portion. The center portion has an inwardly angled tongue. When a plug having a collar is inserted into the electrical connecting jack, the collar comes in contact with the tongue and pushes the central contact portion inward, thus forcing the two ends of the connecting sleeve spring to move outward. The two ends press against the inner periphery of the collar. In this way, the collar makes contact with the connecting sleeve spring at three points; the two ends and the center contact portion. This three point contact arrangement firmly holds and electrically connects the plug to the jack even if there is a gap between the collar and sleeve. The electrical connecting jack also includes a housing with a plurality of contact spring openings. A plurality of contact springs resiliently fit in these openings, electrically connecting the springs to the plug. |
