Abstract
Abstract Disclosed is a modular jack to be mounted on a circuit board, and the modular jack has a printed board containing a noise suppressing electronic element in a housing. The printed board is fitted with contactors for contacting with plugs and terminals to be used for mounting the modular jack on the circuit boad. The contactors and the terminals are electrically connected with the noise suppressing electronic element by wires on the printed board.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
80 words
A modular jack to be mounted on a circuit board, said modular jack comprising: a printed board containing an electronic element for suppressing noise; a contactor for contacting with a plug, said contactor being electrically connected with the electronic element by a wire on the printed board; a terminal for contacting with the circuit board, said terminal being electrically connected with the electronic element by a wire on the printed board; and an insulating housing for encasing the printed board.
Claim 2
Dependent Claim
