<p>A telephone modular jack includes a base for receiving thereon a contact block carrying an array of spring contacts, the corresponding number of terminal units, and a cover, all mounted downwardly upon the base to be capable of being assembled by an automated technique. Each of the terminal units has a lug which is press-fitted to each one of lead tabs extended from the spring contacts when the contact block is mounted on the base. Each spring contact has a first end portion, a middle portion, and a second end portion, the portions being bent with respect to the others. The contact block includes a upright support and a horizontal support in parallel with the base. The middle portion of each spring contact is molded in the upright support in such a manner as to project the first end portion from the top of the upright support diagonally downward to the base, while the second end portion extends through the horizontal support and projects therefrom to define the lead tab at its end. With the provision of the uniquely configured spring contacts and the contact block, the contact block can be mounted on the base so as to effect the press-fit engagement between the spring contacts and the terminal units while positioning the spring contacts to have their leading edges oriented upwardly, thereby making it possible to assemble the cover on the base in the same direction as the contact block and the terminal units.</p> |
