ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to an electric connector, and more particularly to a metal shield and cable arrangement for an electric connector, in which two identical metal shielding shells are mounted in between two cover shells and forced by the cover shells to hold down a cable in therebetween.
Regular electric connectors for use with a computer, printer, or any of a variety of electronic apparatus commonly comprise a terminal holder mounted within a cover shell and holding a set of terminals, and a cable connected to the terminals in the terminal holder. In order to eliminate electromagnetic interference (i.e., EMI), a metal shield or the like shall be used. Further, in order to hold the cable in place, a special cable fastening arrangement is needed. For example, clamping devices are used with the metal shielding shells for securing the cable in place (see FIG.
5
). However, the installation of the additional clamping devices greatly increases the cost of the electric connector, and complicates its assembly procedure.
SUMMARY OF THE INVENTION
The present invention has been accomplished to provide a metal shield and cable arrangement for an electric connector, which eliminates the aforesaid drawbacks. According to one aspect of the present invention, the metal shield and cable arrangement comprises two cover shells fastened together, two shielding shells mounted in between the cover shells to hold a terminal holder, and a cable inserted in between the shielding shells and connected to terminals in the terminal holder, wherein the cover shells each have a neck at one end and a stub rod disposed in the neck; the shielding shells each have a neck fitted into the neck at one cover shell, a through hole coupled to the stub rod in the neck at one cover shell, and a retaining flange of smoothly arched cross section supported on the stud rod in the neck at one cover shell and forced by the stub rod against the periphery of the cable. According another aspect of the present invention, the shielding shells are of identical metal shells made of metal by stamping.
