Abstract
Abstract A subscriber interface box generally shown at comprises a network section and a subscriber section, the network section connected to a network cable and the subscriber section connected to subscriber cables and whereby the network and subscriber sections are electrically connected via a test socket. The subscriber interface box comprises lever members having cavities therethrough for receiving wires of the cables such that the wires can be rapidly connected and disconnected to insulation displacement contacts. The latter is done by placing the wires in corresponding holes of the lever members when the lever members are in an open position, whereby the lever members comprise slots transversely intersecting the wire receiving cavities. The slots for receiving upstanding insulation displacement contacts such that when the levers are pushed down to a close position the wires are forced into electrical contact with the IDC contact slots. Insertion of a test plug into the test socket resiliently biases contact arms that extend from the subscriber to the network section such that there is electrical disconnection therebetween and electrical connection of the network section to the testing plug stop.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
123 words
A subscriber interface box for making electrical connection between a network cable and subscriber cables comprising a base, a subscriber section, a network section, a test socket for receiving a testing apparatus plug, and terminals, whereby the terminals electrically connect the network section to the subscriber section via the test socket such that insertion of the testing apparatus plug into the test socket electrically disconnects the network section from the subscriber section and electrically connects the testing apparatus to the network section, the terminals having insulation displacing contact (IDC) sections for connection to the subscriber or network cables, the interface box further comprising movable stuffer levers having cavities that receive the cables for connecting and disconnecting of the cables to the IDC sections.
Claim 2
Dependent Claim
123 words
A subscriber interface box for making electrical connection between a network cable and subscriber cables comprising a base, a subscriber section, a network section, a test socket for receiving a testing apparatus plug, and terminals, whereby the terminals electrically connect the network section to the subscriber section via the test socket such that insertion of the testing apparatus plug into the test socket electrically disconnects the network section from the subscriber section and electrically connects the testing apparatus to the network section, the terminals having insulation displacing contact (IDC) sections for connection to the subscriber or network cables, the interface box further comprising movable stuffer levers having cavities that receive the cables for connecting and disconnecting of the cables to the IDC sections.
Claim 3
Dependent Claim
43 words
The subscriber interface box of claim 1 characterized in that some of the terminals have a resilient contact portion whereby insertion of the testing apparatus plug into the test socket resiliently biases these contacts to electrically disconnect the subscriber from the network section.
Claim 4
Dependent Claim
72 words
The subscriber interface box of claim 2 characterized in that the test socket comprises a plug receiving cavity and a disconnection insert cavity that extends from the plug receiving cavity to a position adjacent the resilient contact portion, the disconnection insert cavity for receiving a slidable insert that can project through the cavity and abut the resilient contacts for resilient biasing thereof during insertion of the plug into the plug receiving cavity.
Claim 5
Dependent Claim
37 words
The subscriber interface box of any of the preceding claims characterized in that the test socket is mounted to the base via resilient latch means such that the test socket is rapidly replaceable by another test socket.
Claim 6
Dependent Claim
74 words
The subscriber interface box of claim 1 wherein the movable stuffer levers have slots transversely intersecting the cavities for receiving insulation displacement contacts of the terminals, the cavities being movable substantially adjacent to slots of the contacts by manual activation of the levers such that the wires fully inserted in the cavities can be pushed into the contact slots for electrical connection therewith, respectively pulled out of the contact slots for electrical disconnection therewith.
Claim 7
Dependent Claim
26 words
The subscriber interface box of claim 5 wherein the lever comprises a grip extending therefrom for moving the lever by hand without use of a tool.
Claim 8
Dependent Claim
56 words
The subscriber interface box of claim 5 wherein the stuffer lever has a pivot member close to one end thereof and rotatably attached to a lever mounting frame which is in a fixed relation to the insulation displacement contacts, for pivot movement of the stuffer lever while connecting or disconnecting the cables to the IDC sections.
Claim 9
Dependent Claim
34 words
The subscriber interface box of claim 1 wherein the stuffer levers of the subscriber section comprise a plurality of wire receiving cavities for connecting to a plurality of electrical wires of the subscriber cables.
Claim 10
Dependent Claim
26 words
The subscriber interface box of claim 8 wherein the subscriber stuffer levers have a corresponding number of slots for receiving a plurality of IDC sections therein.
Claim 11
Dependent Claim
43 words
The subscriber interface box of claim 1 wherein the terminals of the network section integrally comprise a test socket contact portion, network wire connecting portions, and electrical component contacting portions for connection to electrical components such as a surge protector and RC module.
Claim 12
Dependent Claim
17 words
The subscriber interface box of claim 10 wherein the terminals are stamped and formed from sheet metal.
Claim 13
Dependent Claim
45 words
The subscriber interface box of claim 10 wherein the connecting and contacting portions upstand in a substantially orthogonal direction from a base portion that extends from the network IDC section to the test socket, such that the electrical components are insertable thereover for connection thereto.
Claim 14
Dependent Claim
41 words
The subscriber interface box of claim 1 wherein the box comprises a cover that is split into two parts positionable respectively over the subscriber and network sections, the subscriber section cover part being independently removable for access to the subscriber section.
Claim 15
Dependent Claim
25 words
The subscriber interface box of claim 7 wherein the lever mounting frame comprises hooked shaped pivot bearings that rotatably hold the lever pivot members thereto.
Claim 16
Dependent Claim
107 words
A subscriber interface box for making electrical connection between a network cable and subscriber cables comprising a base, a subscriber section, a network section, a test socket for receiving a testing apparatus plug, and terminals, whereby the terminals electrically connect the network section to the subscriber section via the test socket such that insertion of the testing apparatus plug into the test socket electrically disconnects the network section from the subscriber section and electrically connects the testing apparatus to the network section, wherein the test socket is mounted to the base via resilient latch means such that the test socket is rapidly replaceable by another test socket.
Claim 17
Dependent Claim
