ABSTRACT:
A secondary lock is provided to prevent deflection of a tine and therefore prevent loss of a contact, which can be used in miniature connectors having a large number of contacts and corresponding miniature tines. A first tine (71, FIG. 6 ) at each contact-receiving passage (20) of the connector, has a substantially straight inner tine side (82) extending forwardly and with a radially inward directional component, and has an outer tine side (84) with a forward surface portion (86 A) that extends substantially parallel to the axis of the passage. The secondary lock includes a post (24) that is slidable parallel to the contact-receiving passage and that has a blocking surface (90) that lies close to, but slightly spaced from the forward surface portion of the outer tine side. The forward surface portion (86A) extends forwardly about as far as contact-abutting ends (64, 65) of the tines. The contact-receiving passages are arranged in two concentric circles (21, 23 FIG. 4), with a post-receiving hole (30A) engaging tines at passages lying at each circle. Each post has long ribs (14, FIG. 12 ) to lightly hold the secondary lock in place during shipment, and has short ribs (142) to secure the secondary lock in place after the contacts are installed.
