Abstract
Abstract This Transient Voltage Suppression Device Assemblies (TVSDA) adequately pides for the parasitic inductance of the voltage suppression device (VSD). This TVSDA provides for one connector to be mounted in a plane at each end of the assembly. This mounting arrangement enables bulkhead mounting of the TVSDA. VSD's are connected, in a low parasitic inductance fashion, between leads interconnecting separate connector pins and the body of the TVSDA.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
165 words
A feed-through transient over-voltage suppression device comprising first and second electrical conductive plates; enclosure means attached to said plates so as to create a protected enclosure between said plates; an electrical conductive base positioned in said enclosure and being electrically connected to at least one of said plates; a plurality of connectors passing from outside said enclosure through said first plate to inside said enclosure and back outside through said second plate; a plurality of voltage protection means equal in number to the number of conductors for protecting against transient voltage; said protection means having first and second electrical sides and being mounted to said base such that the first side is electrically connected to said base; and the second side of each protection means being electrically connected respectively to a different conductor inside said enclosure so as to shunt electrical energy from the conductor to the base when a transient voltage occurs; thereby preventing electrical energy from feeding back outside through said second plate.
Claim 2
Dependent Claim
165 words
A feed-through transient over-voltage suppression device comprising first and second electrical conductive plates; enclosure means attached to said plates so as to create a protected enclosure between said plates; an electrical conductive base positioned in said enclosure and being electrically connected to at least one of said plates; a plurality of connectors passing from outside said enclosure through said first plate to inside said enclosure and back outside through said second plate; a plurality of voltage protection means equal in number to the number of conductors for protecting against transient voltage; said protection means having first and second electrical sides and being mounted to said base such that the first side is electrically connected to said base; and the second side of each protection means being electrically connected respectively to a different conductor inside said enclosure so as to shunt electrical energy from the conductor to the base when a transient voltage occurs; thereby preventing electrical energy from feeding back outside through said second plate.
Claim 3
Dependent Claim
46 words
A device as set forth in claim 1 wherein each electrical conductive plate has an opening therethrough; insulation means provided in each opening; and said plurality conductors passing through said insulation means so as to provide for connections inside said enclosure by said voltage protection means.
Claim 4
Dependent Claim
32 words
A device as set forth in claim 2 wherein said first and second electrically conductive plates are located at first and second planes, and said base is located in a third plane.
Claim 5
Dependent Claim
27 words
A device as set forth in claim 3 wherein said plates are circular disks, and said enclosure means is a cylinder which is threaded to one plate.
