Abstract
Abstract A connector bank for cable wires (2,3,4) of telephone cables such that two cable wires (2,4 or 3,4, resp.) connected with each other over the connector bank can be separated from each other, with no need to loosen the respective contact connections. For this, the invention provides for each connecting element (7) a plug (6, 6a) with a contact lug (24, 24a) for insertion into the center contact (11) of the connecting element (7), the plug (6, 6a) being provided with a cable connecting element (20,31) for connection of a cable wire (4).

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
323 words
A connector bank for cable wires of telephone cables, the cable wires being thick dropwire cable wires and thinner cable wires comprising: a plastic connection body defining a plurality of slots, at least one accommodation chamber and a plurality of overvoltage protection chambers; a plurality of connecting elements corresponding to each said slot, each connecting element including a connecting contact, a center contact and a contact spring, each connecting contact, center contact and contact spring being formed integral and positioned within said connection body such that said connecting contact is positioned in said slot with a cutting/clamping member positioned on each side of said slot, said center contact being positioned in communication with said at least one accommodation chamber through an opening in said accommodation chamber and said contact spring being positioned in one of said plurality of overvoltage protection chambers; a plurality of ground contact rails each ground contact rail being positioned within one of said plurality of overvoltage protection chambers and cooperating with one of said contact springs, each of said ground contacts and cooperating contact spring being adapted to receive an overvoltage suppressor in one of said overvoltage protection chambers; and, at least one plug having at least one cable connecting element and a corresponding contact lug, said at least one plug being positionable within said at least one accommodate chamber, said contact lug being positioned adjacent said opening engaging said center contact, thereby allowing one of the thick dropwire cable or thinner cable wires to be connected to said connecting contact in said slot and to be in electrical connection with another thick dropwired cable or thinner cable wire connected to said cable connecting element of said at least one plug and capable of being disconnected by removing said at least one plug without disturbing the cable wire connected to said connecting element of said slot which is still electrically connected to the overvoltage suppressor through said contact spring.
Claim 2
Dependent Claim
323 words
A connector bank for cable wires of telephone cables, the cable wires being thick dropwire cable wires and thinner cable wires comprising: a plastic connection body defining a plurality of slots, at least one accommodation chamber and a plurality of overvoltage protection chambers; a plurality of connecting elements corresponding to each said slot, each connecting element including a connecting contact, a center contact and a contact spring, each connecting contact, center contact and contact spring being formed integral and positioned within said connection body such that said connecting contact is positioned in said slot with a cutting/clamping member positioned on each side of said slot, said center contact being positioned in communication with said at least one accommodation chamber through an opening in said accommodation chamber and said contact spring being positioned in one of said plurality of overvoltage protection chambers; a plurality of ground contact rails each ground contact rail being positioned within one of said plurality of overvoltage protection chambers and cooperating with one of said contact springs, each of said ground contacts and cooperating contact spring being adapted to receive an overvoltage suppressor in one of said overvoltage protection chambers; and, at least one plug having at least one cable connecting element and a corresponding contact lug, said at least one plug being positionable within said at least one accommodate chamber, said contact lug being positioned adjacent said opening engaging said center contact, thereby allowing one of the thick dropwire cable or thinner cable wires to be connected to said connecting contact in said slot and to be in electrical connection with another thick dropwired cable or thinner cable wire connected to said cable connecting element of said at least one plug and capable of being disconnected by removing said at least one plug without disturbing the cable wire connected to said connecting element of said slot which is still electrically connected to the overvoltage suppressor through said contact spring.
Claim 3
Dependent Claim
37 words
A connector bank according to claim 1, wherein: said at least one plug includes two cable connecting elements each having one contact lug, each contact lug being associated with a single slot and a single center contact.
Claim 4
Dependent Claim
42 words
A connector bank according to claim 1, wherein: said plastic body includes an accommodation channel including a plurality of accommodation chambers for a plurality of plugs, each plug having several cable connecting elements, said accommodation channel being arranged in a longitudinal direction.
Claim 5
Dependent Claim
