Abstract

A hinged mounting bracket and attachable ground bar used in conjunction with a telephone wire termination block. The mounting bracket is adapted to accept modular connectors in order to form any size connecting block. The hinged bracket consists of two pieces, a bracket base and a front flap which receives the modular connectors. In a preferred embodiment, the front flap is coupled to the base by a hinge which enables the bracket to rotate open so that rear terminals of the modular connectors may be easily accessed. The ground bar is attachable to the front or rear of the mounting bracket in order to provide a ground for gas tube circuit protectors that may be inserted into the modular connectors. The ability to secure the ground bar to the mounting bracket in a variety of orientations provides additional flexibility for all types of wiring schemes. In a preferred embodiment of the invention, the ground bar couples to support posts on the mounting bracket utilizing a force fit insertion. A tab on the ground bar creates a bias against the support posts to retain the ground bar in a fixed position. Individual circuit protection modules are adapted to be received on the ground bar which establishes a positive seat connection.

Claims

1. In a modular connecting block system for termination of wires, wherein connector modules having a plurality of terminals facing a front and rear side thereof are insertable within a mounting bracket for mounting of said connecting block, said bracket including a plurality of support posts aligned on either side of said bracket for retaining said connector modules, a ground bar apparatus for attachment to said bracket, said ground bar apparatus comprising:

a unitary metallic strip formed into three distinct sections including,

first and third sections including fastening means for fastening to said support posts of said bracket to thereby electrically couple said ground bar to said bracket, and

a second section perpendicularly coupled between said first and third sections, said second section including a ground bus adapted to electrically couple with circuit protection modules installable in a front and rear side of said connector modules, wherein said fastening means of said first and third sections is adapted to couple to front facing and rear facing ends of said support posts of said bracket.

2. The system of claim 1, wherein said fastening means comprises a clip for attachment of said ground bar to said support posts.

3. The system of claim 2, wherein first and third sections comprise generally flat thin members each having a cutout disposed therein, wherein material from said cutout remains attached at one end to said members and is bent outward to form a tab, and wherein said tab is adapted to slide over said support posts of said bracket for attachment thereto.

4. The system of claim 3, wherein said tab is adapted to bias against said support posts in order to create a force fit.

5. The system of claim 1, wherein said ground bus includes a rounded protrusion extending longitudinally along one edge thereof, wherein a positive seat is established for coupling of said circuit protection modules thereto.

6. The system of claim 2, further including said mounting bracket having said support posts extending vertically upward therefrom, wherein said support posts each include a slot at a base portion thereof where said posts couple to said bracket, said slot being adapted to receive therethrough a portion of said clip from said fastening means to thereby enable attachment of said ground bar on a rear side of said bracket.

7. The system of claim 6, wherein said mounting bracket includes a front and back plate couplable to one another, wherein said front plate is openable to gain access to said rear facing side of said connector modules and said ground bar apparatus when said ground bar is mounted in the rear of said bracket.

8. The system of claim 6, wherein said ground bar and mounting bracket are comprised of a rigid conductive material.

9. The system of claim 6, wherein said front plate includes a row of generally rectangular slots disposed adjacent said support posts, wherein a single slot and pair of said support posts on either side of said plate define a receptacle area for insertion of a single one of said connector modules.

10. The system of claim 7, wherein said front and back plates are coupled by means of a hinge mechanism.

22. The system of claim 7, including a force-fit coupling arrangement between said front and back plates, wherein said front plate snaps onto said back plate, said front plate being removable.

11. A combination mounting bracket and ground bar apparatus for use with modular connectors for termination of wires, said modular connectors having terminals on a front and rear facing side thereof for accepting said wires and said connectors being adapted to receive circuit protection modules for protecting equipment coupled to said telephone circuits, said combination comprising:

a mounting bracket including a plurality of receptacle areas for receiving said modular connectors, said receptacle areas each including a pair of outwardly projecting support posts adapted to retain said connectors, and

a grounding bar attachable to said support posts of said mounting bracket, said grounding bar including fastening means adapted to attach to a front facing and rear facing side of said bracket, wherein said grounding bar upon attachment is oriented proximate said connector modules, whereby said circuit protection modules couple to said ground bar to establish a discharge path therefor.

12. The combination of claim 11, wherein said ground bar includes

first and second sections including said fastening means to electrically couple said ground bar to said bracket, and

a third section perpendicularly coupled between said first and second sections, said third section including a ground bus adapted to electrically couple with said circuit protection modules.

13. The combination of claim 12, wherein first and second sections comprise generally flat thin members each having a cutout disposed therein, wherein material from said cutout remains attached at one end to said members and is bent outward to form a tab, and wherein said tab is adapted to slide over said support posts of said bracket for attachment thereto.

14. The combination of claim 13, wherein said tab is adapted to bias against said support posts in order to create a force fit.

15. The combination of claim 11, wherein said ground bar includes a rounded protrusion extending longitudinally along one edge thereof, wherein a positive seat is established for coupling of said circuit protection modules thereto.

16. The combination of claim 13, wherein said support posts each include a slot at a base portion thereof, said slot being adapted to receive said tab to thereby enable attachment of said ground bar on a rear side of said bracket.

17. The combination of claim 11, wherein said mounting bracket includes a front and back plate removably attached to one another, wherein said front plate is openable to gain access to said rear facing side of said connector modules and said ground bar apparatus when said ground bar is mounted in the rear of said bracket.

18. The combination of claim 11, wherein said ground bar and mounting bracket are comprised of a rigid conductive material and said ground bar comprise a unitary strip of said material.

19. The combination of claim 17, wherein said front plate includes a row of generally rectangular slots disposed between adjacent support posts, wherein a single slot and pair of said support posts on either side of said plate define said receptacle area for insertion of a single one of said connector modules.

20. The combination of claim 17, wherein said front and back plates are coupled by means of a hinge mechanism.

21. The combination of claim 17, wherein said front and back plates couple together in a snap-fit arrangement.
