Abstract
The utility model relates to a network surge protector and installation structure thereof. The network surge protector comprises a surge protector, and is characterized in that the network surge protector includes a secondary combination protection circuit consisting of an interface, a guide rail, a gas discharge pipe and a transient suppression diode; the gas discharge pipe and the transient suppression diode; and the transient suppression diode is serially connected with a common diode. The installation structure has such interface installation manner that the interface gets in and out at the same terminal or gets in at the front terminal or gets out at the rear terminal. A cabinet can be arranged directly due to the addition of a left mounting sheet and a right mounting by adopting guide rail installation. A grounding bus bar is externally connected with a grounding wire or is fastened by a bolt. The network surge protector has the advantages of diverse and convenient installation modes, high maximal transmission frequency, low corresponding insertion loss, and less voltage protection level.
Description
Technical field
The utility model relates to a kind of network surge protector and mounting structure thereof, belongs to electric lightning-protection engineering field.
Background technology
Current society is the epoch of electronic technology develop rapidly, microelectronic device is widely used in various communication equipments---comprise Computer Data Communication, terminal equipment, program controlled telephone etc., temperature, flow, pressure sensor, the secondary instrument and meter of industry real-time monitoring system all adopt the various signals of MICROCOMPUTER PROCESSING, the hardware components of these communications, computer equipment adopts TTL or COMS integrated circuit mostly, its operating voltage is all lower, for transducers such as temperature, flow, the pressure weak signal of mV level especially; The TTL circuit voltage is 5V; The COMS circuit voltage is 3～18V; The operating voltage of supervisory control system: 0～10mA is 12V, and 4～20mA is approximately 24V; The dialing lineman is 110V as voltage, and the operating voltage of special line or leased line is 12V or 24V.
Latticed form is extensively adopted in compunication signal or information processing at present, can be divided into local area network (LAN), wide area network etc., these networks all need long Network transmission line, and signal transmission distance is also far away between one, the two=inferior table of supervisory control system, generally have tens or rice up to a hundred long.Because transmission range is far away, transmission line is longer, also just increased greatly by the probability of indirect lightning strike, the operating voltage of hardware device is lower in addition, the ability of anti-thunderbolt weakens, and in order to guarantee the safe operation of various electronic equipments, it is very necessary installing the electronics lightning arrester additional.
Summary of the invention
The purpose of this utility model is to propose a kind of network surge protector and mounting structure thereof, and this network surge protector can prevent overvoltage and can lightning protection solve the device security technical problem.
For achieving the above object; technical solution scheme of the present utility model is: this surge protector comprises interface, guide rail, and gas is put pipe and transient state suppresses the secondary combination protective circuit that diode constitutes; four bars circuits in the RJ45 interface are taked the anti-overvoltage protection.Because the product of the technical program is used for the lightning protection of microelectronic device; need very low voltage protection level and fast-response time; put pipe and transient state inhibition diode so adopt gas; wherein gas discharge tube plays the effect of most of lightning current of releasing, and transient state suppresses the effect that diode plays deboost.
But because the parasitic capacitance of transient state inhibition diode is bigger, about 5000pf-10000pf, under the transmission conditions of upper frequency, parasitic capacitance produces decay for high-frequency signal, thereby influences the normal transmission of signal simultaneously.Adopt general-purpose diode and transient state to suppress diode and connect,, reduce the parasitic capacitance of integrated circuit,, make its total parasitic capacitance less than 50pf through series connection with the general-purpose diode low parasitic capacitance.When in the circuit positive and negative overvoltage being arranged, the conducting respectively of the diode at two ends suppresses diode through follow-up transient state again, restraining line and line, and the voltage levvl between line and the ground plays a protective role.
The beneficial effects of the utility model: maximum transmitted frequency height, it is little to insert loss accordingly, and less voltage protection level is arranged simultaneously.
