Patent number: 9531140Abstract: A protective device for transmitting electromagnetic signals includes an inner conductor that extends coaxially within an outer conductor. To compensate for dimensional tolerances without compromising performance, inner conductor is constructed to include a center pin with a conical end, a plunger pin slidably disposed within an axial bore in the center pin, the plunger pin including a conical end located outside the center pin, and a resilient, expandable, conductive band coaxially mounted onto the conical ends of the center and plunger pins. A gas discharge tube is conductively coupled between the inner and outer conductors to discharge transient voltages transmitted along the inner conductor. To minimize disturbance to the transmission line, the width of the gas discharge tube in the region of contact with the inner conductor is preferably equal to the diameter of the inner conductor. Additionally, the gas discharge tube is preferably greater in length than in width.Type: GrantFiled: December 19, 2013Date of Patent: December 27, 2016Inventor: George M. Kauffman
