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

1. 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.

2. 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.

3. 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.

4. A connector bank according to claim 1, wherein:

said plastic body includes a plurality of accommodation chambers each adapted to receive a plug, each accommodation chamber including vertical ribs adapted to engage corresponding grooves in said plug.

5. A connector bank according to claim 1 wherein:

said opening in said plastic body is in the form of a cross-shaped opening, the position of said cross-shaped opening corresponding to the position of said contact lugs when said plug is positioned within an associated accommodation chamber.

6. A connector bank according to claim 1, wherein:

each of said cable connecting elements associated with one of said plugs including a terminal screw and a metal plate connected with said contact lug, said terminal screw and said metal plate cooperating to make electrical contact with a cable wire.

7. A connector bank according to claim 1, wherein:

each of said cable connecting elements associated with said plug includes a cutting/clamping contact formed integral with said contact lug.

8. A connector bank according to claim 1, wherein:

said plug being a test plug adapted to be connected to said connector bank while maintaining connection between said connecting contact and said overvoltage suppressor.

9. A connector bank according to claim 1, wherein:

said plastic body includes a front face having a guide adapted to cooperate with a corresponding groove of said at least one plug.

10. A connector bank according to claim 7, wherein:

said plug includes a plug body and a plug cover, said plug cover being connected to said plug body by a film hinge, said cover being provided with a press-in crosspiece adapted to cooperate with said cutting/clamping contact element to press a cable wire into the cutting/clamping contact element.

11. A connector bank according to claim 10, wherein:

said plug cover includes notches cooperating with corresponding counter notches of said plug body, said counter notches engaging in said notches to connect said plug body and said plug cover.
