Abstract
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.
Description
Technical field
The present invention relates to the lightning protection analog network dish in the naked frequency-shift automatic blocking system in the railway signal system, is lightning protection analog network dish 35 core plugs and socket specifically.
Background technology
At present, (10/700us waveform when lightning protection analog network dish carries out the vertical lightning protection of 0 kilometer cable side of receiving end test in the naked frequency-shift automatic blocking system, voltage magnitude 5kV), there are 35 core plugs 10, socket 20(in lightning protection analog network dish inside referring to Fig. 1), this 35 core plug is, 35 contact pins divide two rows to be fixed on the Plug pin patch bay, and wherein a row is 18 contact pins 11, another row is 17 contact pins, the stiff end of two socket pins be 2.54mm apart from d; The primary and secondary exit of the lightning protection transformer on this 35 core socket is not have dividing plate between 1,2 terminals (being jack 21, jack 22) and 3,4 terminals (being jack 23, jack 24), cause the primary and secondary discharge of lightning protection transformer, isolation descends, make the thunder and lightning interference signal stride across lightning protection transformer and directly enter system, cause the attenuation redundant manipulator of back level in the system, the damage of receiver.
Summary of the invention
For solving the problems of the technologies described above, the purpose of this invention is to provide a kind of 35 core plugs, socket of high lightning protection grade of lightning protection analog network dish.
The object of the present invention is achieved like this: plug comprises two socket pins, and socket comprises primary and secondary exit i.e. 1,2 jacks and 3,4 jacks, and it is characterized in that: the distance of the stiff end of two socket pins on the plug is 5.08mm; Between 1 on the socket, 2 terminals and 3,4 terminals, division board is set, will isolates between 1,2 terminals and 3,4 terminals.Increased creepage distance like this, can make lightning protection analog network dish keep out the thunder and lightning interference signal of 8kV in 0 kilometer cable side test of receiving end, system still can normally move.
Compare with existing equipment, effect of the present invention is: when being struck by lightning, improve the protective capability to equipment greatly.Improved equipment lightning protection grade.
Description of drawings
Further specify the present invention below in conjunction with accompanying drawing.
Fig. 1 is 35 core plugs of existing lightning protection analog network dish and the schematic diagram of socket.
Fig. 2 is a schematic diagram of the present invention.
Embodiment
Referring to Fig. 2, plug 10 comprises two socket pins, the stiff end of two socket pins on the plug be 5.08mm apart from d '; The primary and secondary exit of the lightning protection transformer on the socket is to be provided with between 1,2 terminals (being jack 21, jack 22) and 3,4 terminals (being jack 23, jack 24) highly to be the division board 3 of 2mm, will isolate between 1,2 terminals and 3,4 terminals.Increased creepage distance like this, can make lightning protection analog network dish keep out the thunder and lightning interference signal of 8kV in 0 kilometer cable side test of receiving end, system still can normally move.
Claims (2)
1. lightning protection analog network dish 35 core plugs, socket, plug comprises two socket pins, and socket comprises primary and secondary exit i.e. 1,2 jacks and 3,4 jacks, and it is characterized in that: the distance of the stiff end of two socket pins on the plug is 5.08mm; Between 1 on the socket, 2 terminals and 3,4 terminals, division board is set, will isolates between 1,2 terminals and 3,4 terminals.
2. according to the described lightning protection analog network of claim 1 dish 35 core plugs, socket, it is characterized in that: it is characterized in that: the height of said division board is 2mm.
