Abstract
Abstract An arrangement of fanning strip and terminal block having mutually engageable interlocking structures which allow for mounting of the fanning strip upon and disconnection of the fanning strip from the terminal block from one side of the terminal block only. In practical constructions, the interlocking structures are rails and complementary slots. These may be of any suitable cross-section, e.g. L-shaped or dovetail shaped.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
116 words
A fanning strip member and terminal block member arrangement comprising a terminal block member having a first side with terminal mounting positions for electrical conductor wires, a second and opposite side for engagement with a terminal block support member, and a third side extending between the first and second sides, and a fanning strip member for location along the third side of the terminal block member, the fanning strip member and said third side having mutually engageable interlocking means for mounting the fanning strip member on said third side with the fanning strip member being detachable from the terminal block member solely by movement of the fanning strip member in the direction of the second side.
Claim 2
Dependent Claim
116 words
A fanning strip member and terminal block member arrangement comprising a terminal block member having a first side with terminal mounting positions for electrical conductor wires, a second and opposite side for engagement with a terminal block support member, and a third side extending between the first and second sides, and a fanning strip member for location along the third side of the terminal block member, the fanning strip member and said third side having mutually engageable interlocking means for mounting the fanning strip member on said third side with the fanning strip member being detachable from the terminal block member solely by movement of the fanning strip member in the direction of the second side.
Claim 3
Dependent Claim
90 words
An arrangement according to claim 1 wherein the mutually engageable interlocking means comprises at least one rail extending from the fanning strip member and a rail receiving slot in the third side of the terminal block member, the rail and slot orientated to receive the rail into the slot progressively as the fanning strip member is mounted onto said third side in a direction from the second side towards the first side of the terminal block member, the fanning strip member being limited in its movement in the mounting direction.
Claim 4
Dependent Claim
40 words
An arrangement according to claim 2 wherein the rail and slot are both tapered along their lengths to permit insertion of the rail into the slot until the tapering surfaces of the rail interlockingly engage tapering surfaces of the slot.
Claim 5
Dependent Claim
29 words
An arrangement according to claim 3 wherein the slot extends upwardly from the second side towards the first side and terminates in a position spaced from the first side.
Claim 6
Dependent Claim
30 words
An arrangement according to claim 2 wherein the or each rail is L-shaped in cross-section and is integrally attached to the fanning strip member by one leg of the rail.
Claim 7
Dependent Claim
15 words
An arrangement according to claim 2 wherein the or each rail is of dovetail cross-section.
Claim 8
Dependent Claim
87 words
An arrangement according to claim 1 wherein the mutually engageable interlocking means comprises at least one rail extending from one of the members and a complementary shaped rail receiving slot in the other member, the rail and slot orientated to receive the rail into the slot progressively as the fanning strip member is mounted onto said third side in a direction from the second side towards the first side of the terminal block member, the fanning strip member being limited in its movement in the mounting direction.
Claim 9
Dependent Claim
38 words
An arrangement according to claim 7 wherein the rail and slot are tapered along their lengths to permit insertion of the rail into the slot until the tapering surfaces of the rail engage tapering surfaces of the slot.
Claim 10
Dependent Claim
30 words
An arrangement according to claim 7 wherein the or each rail is L-shaped in cross-section and is integrally attached to the fanning strip member by one leg of the rail.
Claim 11
Dependent Claim
15 words
An arrangement according to claim 7 wherein the or each rail is of dovetail cross-section.
