ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to electrical connectors and more specifically to cable connectors and cable interconnections, and especially to such cable connectors that are shielded.
2. Brief Description of Prior Developments
Cable connectors have been developed that employ shielding to maintain signal integrity during passage of high speed electrical signals. Such developments characteristically include strain relief mechanisms for providing strong attachment to the cable so that individual conductors remain secured to the terminals within the connector.
In addition, latching systems have been proposed for securing cable connectors to mating connectors, especially connectors that are mounted on the circuit boards or equipment with which the cable is to be associated. One such shielded cable connector with an associated latching arrangement is shown in International Application Serial No. PCT/US97/10063, the disclosure which is hereby incorporated by reference. That application is owned by the assignee of this present application. While the shielded connectors and latching systems disclosed in the above noted application provide improved shielding and latching characteristics, there is a desire to improve these connectors and make them more space efficient.
SUMMARY OF THE INVENTION
In order to improve the attachment of a shielded connector onto a cable, an improved means and method for providing strain relief was developed. A strain relief member is placed on the cable prior to attachment of other parts of the connector to the cable. A terminal block is secured on the conductors of the cable, the shielding sheath of the cable is associated with a ferrule of the strain relief member, and the shielding member is placed around the terminal block and in mounting relationship with the strain relief member. Parts of the shield member may be associated with the strain relief member. Thereafter a clamp is applied to clamp the shielding sheath and preferably an outer insulating cover of the cable on the strain relief ferrule.
A latch member is provided on a connector with which the cable connector is to be mated. The latch may engage portions of the strain relief member or other portions of the cable connector. Structure is provided for removably mounting latching members on a connector housing using simple tools or latch parts for demounting the latch.
