ABSTRACT:
An improved modular jack, and more particularly to a keystone jack for use on digital communication networks intends to effectively avoid short circuits and the production of noise and crosstalk in signal transmission. The jack is equipped with a wire mounting plate having four receiving grooves on the top face and four on the bottom face thereof some of which are crossly oriented at their ends so as to permit 8 or more wire contact pieces to be mounted separately thereto and crossly placed without contact at all. A retaining board is integrally engaged with the top face of the wire mounting plate and the combination is forced into a receiving recess of a jack housing having a horizontal extension to support the bottom face of the wire mounting plate so as to fix the 8 wire contact pieces respectively in place. Then a wire limiting cap having a horizontally defined cable insertion hole is engaged with the jack housing so as to permit a cable to be vertically led into the jack with its 8 wires connected to the horizontal wire contact pieces.
