Self locking joint between a ball head rod and a flat part

摘要

The self-locking connection (1) between a ball joint rod (2) and a plane part comprises a press button and a lock (4). The lock is made from a single cylindrical part (41) having at one of its ends a zone (42) for locking the press button inside the part. At the other of its ends are several flexible tabs (43) with a lower part curved to the inside of the part forming a circle of diameter (D) less than that (D') of the ball joint and adapted to separate during the introduction of the ball joint inside the part and to close after its introduction. Independent claims are included for a method of making the self-locking connection and its use for connecting an automobile brake amplifier rod to the brake pedal.
