Description
Technical field
The utility model relates to communication field, particularly relates to the Surge Protector of a kind of Fast Ethernet transmission.
Background technology
A lot of harmonic filtration product is had in communication field; for the protection of power-supply system not by external interference; keep good Circuits System; but problem is that main high-frequency harmonic interference (90%) is equipment generation itself, interference powers meeting interference mutually that these are produced by equipment itself, impact and damage equipment, cause power consumption to increase; equipment use efficiency reduces; faults frequent, thus add cost, and main circuit protection can not prevent these from damaging.In addition; the Surge Protector of at present a lot of protection ethernet signal transmission can only reach 100,000,000 due to the most high transmission speed of the factors such as design selection; and the gigabit transmission speed requirement of high-end devices needs can not be met; and Surge Protector presents the phenomenons such as distributed capacitance is larger at high band; and cause network insertion loss to increase; signal attenuation, affects Internet Transmission, can not meet the needs of routine work.
Utility model content
The Surge Protector that the utility model aims to provide a kind of network performance, parameter is more optimized, the overvoltage that the overvoltage, surge current and the internal system that make equipment not produce by indirect lightning strike when ensureing network transfer speeds and accuracy produce, the damage of surge current.
For achieving the above object, the technical solution adopted in the utility model is as follows:
Surge Protector disclosed in the utility model; comprise: the two ends difference contact resistance R1 of the parallel branch be made up of electrode surge arrester V1 and two pole discharge tube V2, one end of resistance R2; the other end of described resistance R1, resistance R2 connects the two ends of electrostatic protector T1 respectively, the contre electrode ground connection of described electrode surge arrester V1.
Two pole discharge tubes of the utility model parallel connection one on electrode surge arrester, overvoltage and overcurrent between line of can better releasing, better to ensure Signal transmissions between line.
Further, one end of described resistance R1, resistance R2 connects two pins of plug connector J1 respectively, and the other end of resistance R1, resistance R2 connects two pins of plug connector J2, the earthing of casing of described plug connector J1, plug connector J2 respectively.
Preferably, described plug connector J1, plug connector J2 are RJ45 joint.
Preferably, described electrostatic protector is SLVU2.8-4ESD, and the puncture voltage of described electrode surge arrester V1 is 75V, and the puncture voltage of two pole discharge tube V2 is 90V.
The utility model can the damage of the proterctive equipment overvoltage that overvoltage, surge current and the internal system that produce do not produce by indirect lightning strike, surge current better when not affecting signal transmission performance.
Accompanying drawing explanation
Fig. 1 is the utility model circuit theory diagrams.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with accompanying drawing, the utility model is further elaborated.
As shown in Figure 1, Surge Protector disclosed in the utility model, comprise: the two ends difference contact resistance R1 of the parallel branch be made up of electrode surge arrester V1 and two pole discharge tube V2, one end of resistance R2, the other end of resistance R1, resistance R2 connects the two ends of electrostatic protector T1 respectively, the contre electrode ground connection of described electrode surge arrester V1; One end of resistance R1, resistance R2 connects two pins of plug connector J1 respectively, the other end of resistance R1, resistance R2 connects two pins of plug connector J2 respectively, the earthing of casing of plug connector J1, plug connector J2, plug connector J1, plug connector J2 all adopt RJ45 joint, during use, plug connector J1 connects signal input, and plug connector J2 connects signal and exports.
Further, by electrode surge arrester V3, V5, V7 and two pole discharge tube V4, V6, V8, resistance R3 and R4, resistance R5 and R6, resistance R7 and R8, electrostatic protector T2, T3, T4 forms three road Surge Protectors respectively, integrate, be applicable to the surge protection of 4 road signals, for the surge protection of Ethernet gigabit signal, electrode surge arrester V1, V3, V5, V7 all adopts puncture voltage to be the gas discharge tube of 75V, two pole discharge tube V2 all adopt puncture voltage to be the gas discharge tube of 90V, resistance R1, R2, R3, R4, R5, R6, R7, the resistance of R8 is 2.2 Ω, power is 1W, electrostatic protector is SLVU2.8-4ESD, for electrostatic protector T1, T2, T3, T4, can be a unit of SLVU2.8-4ESD respectively.
The device that the utility model uses is protective device, it is high impedance status under normal condition, because extremely low distributed capacitance can't affect Signal transmissions usually, only when line influence lightning current or high voltage, surge current can be released rapidly into ground by the ns level response speed of device, simultaneously by voltage clamping in lower voltage range.Its key advantage is, through test energy Long-Time Service after combination of devices uses, all protects 4 pairs of holding wires transmission, starting resistor is lower, distributed capacitance reduces greatly, does not affect the test that Signal transmissions also can stand lightning test, is applicable to 100M or 1000M Internet Transmission.
Certainly; the utility model also can have other various embodiments; when not deviating from the utility model spirit and essence thereof; those of ordinary skill in the art can make various corresponding change and distortion according to the utility model, but these change accordingly and are out of shape the protection range that all should belong to the claim appended by the utility model.
