Plug connector for cable television network and method of use
A telecommunications apparatus for use with a plug having at least first, second and third pins. The telecommunications apparatus includes a plug connector for receiving the plug. The plug connector includes at least first, second and third electrical contacts for electrically contacting the first, second and third pins, respectively, when the plug is inserted in the plug connector. The plug connector also includes an electrical by-pass pathway that: i) electrically connects the first and second electrical contacts when the plug is fully removed from the plug connector such that a signal can enter the plug connector through the first contact, pass through the by-pass pathway to the second contact, and exit the plug connector through the second contact; and ii) does not electrically connect the first and second electrical contacts when the plug is fully inserted within the plug connector such that a signal can enter the plug connector through the first contact, pass through the plug to the second contact, and exit the plug connector through the second contact.
1. An equalizer module, comprising:
a) a printed circuit board;
b) an equalizer plug having two through pins and two ground pins; and
c) a connector housing mounted on the printed circuit board, the housing including two through springs and two ground springs;
d) wherein a first electrical connection is made between the two through springs of the housing when the plug is fully inserted into the housing; and
e) wherein during removal of the plug from the housing, a second electrical connection is made between the two through springs prior to breaking the first electrical connection.
2. The module of claim 1 , further including a coax connector, the coax connector being electrically connected to one of the two through springs.
3. The module of claim 2 , further including a directional coupler, the directional coupler being electrically connected to the other of the two through springs.
4. The module of claim 1 , wherein the two ground springs of the connector housing are grounded through the printed circuit board.
5. The module of claim 1 , wherein the second electrical connection is defined in part by two contacts, the two through springs of the housing being normally biased against the two contacts such that the second electrical connection is established during removal of the plug from the housing.
6. The module of claim 5 , wherein the two through pins of the plug are arranged to force the two through springs of the housing out of contact with the two contacts when the plug is fully inserted into the housing.
7. The module of claim 5 , wherein the two through springs are in contact with both the two contacts that define the second electrical connection, and the two through pins of the plug, when the plug is in an intermediate position during removal of the plug from the housing.
8. The module of claim 7 , wherein the two ground springs are in contact with the two ground pins when the plug is in the intermediate position.
