The invention provides a 35-pin plug and a 35-pin socket for a lightning protection analog network disk and aims to solve the problem that no septum is arranged between the terminals (1 and 2) and the terminals (3 and 4) of the primary and secondary leading-out terminals of a lightning protection transformer on a conventional 35-pin socket, so that the primary and secondary electric discharge of the lightning protection transformer and the decline of isolation are caused and thunder and lightning interference signals are enabled to directly enter a system across the lightning protection transformer. The key points are that the distance between the fixed ends of two lines of contact pins on the 35-pin socket is 5.08 mm; and a septum is arranged between the terminals (1 and 2) and the terminals (3 and 4) on the 35-pin socket to separate the terminals (1 and 2) from the terminals (3 and 4). Thus, a creep age distance is increased, the lightning protection analog network disk is enabled to resist an 8 kV thunder and lightning interference signal in a receiving-end 0-kilometer cable side test, and the system can still run normally.
