Abstract
Abstract A lightning protector carrier comprises a lamellar element made of electrically insulating material and having a plurality of sets of holes therethrough each set of holes defining a respective socket to receive a respective lightning protector device, and a plurality of electrically conducting terminals for making electrical connection to lightning protector devices at a front face of the element. One hole of each set of holes accomodates a terminal and the terminals are electrically interconnected by one or more busbars at the rear of the element. At least the front surface of the element is shaped such that one hole of each set is separated from another hole of the set by a protruding portion of the element interposed between said one hole and said another hole.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
160 words
A lightning protector carrier comprising a lamellar element made of electrically-insulating material and having a plurality of sets of holes extending directly therethrough from a front face to a rear face of the element, a respective set of electrically-conducting terminals for each of said sets of holes, each terminal being accommodated in a respective one of the holes and extending therethrough from the front face to the rear face of the element whereby each set of terminals provides, at the front face of the element, a socket to receive a respective lightning protector device and, at the rear face of the element, means for making electrical connections from the socket to conductors, and at least one busbar interconnecting preselected ones of said terminals at the rear face of the element, at least one of the said faces of the element being formed with integral protruding portions interposed between said holes to separate the terminals of a set from each other.
Claim 2
Dependent Claim
160 words
A lightning protector carrier comprising a lamellar element made of electrically-insulating material and having a plurality of sets of holes extending directly therethrough from a front face to a rear face of the element, a respective set of electrically-conducting terminals for each of said sets of holes, each terminal being accommodated in a respective one of the holes and extending therethrough from the front face to the rear face of the element whereby each set of terminals provides, at the front face of the element, a socket to receive a respective lightning protector device and, at the rear face of the element, means for making electrical connections from the socket to conductors, and at least one busbar interconnecting preselected ones of said terminals at the rear face of the element, at least one of the said faces of the element being formed with integral protruding portions interposed between said holes to separate the terminals of a set from each other.
