ABSTRACT:
A method of making a one piece insert (10) for retaining a plurality of electrical contacts (20) in an electrical connector. The insert (10) includes a plurality of bores or passageways (15) having integral with the insert means for retaining a contact within each of the insert passages. The integral means for retaining a contact (20) includes a plurality of radially deflectable contact retaining fingers (11) adjacent a plurality of ribs (16). Shoulders (17) on the ribs (16) and the free ends (12) of the retention fingers (11) engage forwardly and rearwardly facing shoulders (21, 22) on a contact, thereby captivating a portion (25) of the contact within the insert. The radially deflectable fingers (11) in the insert allow a contact to be inserted and removed from one end of an electrical connector. The method of making the insert includes two mold halves (70, 80) and a core pin (50) mounted to one mold half (70) and a mating core bushing (60) mounted to the other mold half (80) for each passage which is desired. The structure (54, 55) of the core pin (50) which mates with the structure (64, 65) of the core bushing define the shoulders (17), the ribs (16) and the deflectable fingers (11), which are formed in the molding process.
