Description
Technical field
The utility model relates to a kind of parts of lightning protection device, relates to a kind of coaxial configuration radio frequency lightning protection device inner wire specifically; Belong to the shocking preventing technology field.
Background technology
Along with the progress of society and the raising of quality of life, human requirement and function to radio communication also changes thereupon, and radio communication is by the evolution of 2G to 3G, and the generation of 3G technology has met social development and demand with application.Because the characteristic requirements base station construction density of 3G technology is high and with former GSM system equipment can not general fully (equipment need be done and change or upgrading); Therefore the early investment of 3G network is very high; Along with 3G requires increasingly high the time communications, the lightning protection of 3G communication system also becomes the most important thing like this.As the 3G system, the whole system protection is mainly contained: direct lightning strike protects, draws port, the intermediate frequency that external power, integrated tower are put to zoom out circuit, GPS radio frequency, power line and control line etc.The lightning protection of wherein relevant radio-frequency apparatus is part and parcel very in the lightning-protection system; At present for the still radio frequency lightning protection devices that adopt low power repeater RF communication systems such as GSM, GPS, CDMA, TD-SCDMA of the radio frequency lightning protection of 3G system more; Though this type lightning protection device also is referred to as the coaxial radio-frequency lightning protection device; But in fact be not the coaxial configuration of standard, characteristics such as its product build is big, assembly program is complicated, index error, cost height are difficult to satisfy the lightning protection requirement of 3G system.Structure can find out from accompanying drawing 1 that shown in accompanying drawing 1 existing radio frequency lightning protection device is by mainly being made up of outer conductor 1, outer conductor 2, discharge tube trip bolt 3, inner wire 4, dielectric 5, discharge tube 6.The main deficiency of this product is following:
The big cost of 1 volume is high: because discharge tube is to compress from the outside through a trip bolt, make discharge tube be close in the conductor, keep contacting with inner wire; So just require the volume of outer conductor 2 to want enough big, so just can have living space the discharge tube trip bolt is installed, so the product material cost is also very high;
2 is not the coaxial cavity of standard: because the discharge tube trip bolt is the main device that is used to compress discharge tube 6; Therefore must inner chamber body be punched; So just destroy the coaxial cavity structure of former lightning protection device, caused the frequency range of insertion loss and standing-wave ratio index error, product of product narrow;
The inner wire complex structure of 3 lightning protection devices; The inner wire of existing coaxial radio-frequency lightning protection device generally all is to adopt fabricated structure; The two ends of inner wire are respectively two mandrels; Two mandrels get up through the intermediate sleeve pipe box, and two mandrels of inner wire are through being fixed in the outer conductor inner chamber through dielectric respectively; Discharge tube is installed in intermediate casing and puts, and fastening by the screw on the outer conductor, and the assurance discharge tube contacts with the inner wire intermediate casing.The structure of this kind inner wire is comparatively complicated, will keep relatively difficulty of axiality during assembling, and be easy to damage.Practical application proves the inner wire of this structure, originally thinks after discharge tube is breakdown to make lightning protection device continue and can use through changing discharge tube; But in fact; After discharge tube punctured because of thunderbolt, inner wire can be damaged equally, also will need to change; And this baroque inner wire structure is brought some unnecessary troubles to replacing.
Retrieval is not found relevant for the patent aspect the coaxial radio-frequency lightning protection device as yet on the Chinese patent board web; Just find the radio frequency lightning protection device of some relevant radio frequency lightning protection; Like the patent No. is ZL200920135513; Name is called the Chinese patent of " wide band radio-frequency lightning protection device ", discloses a kind of wide band radio-frequency lightning protection device.It comprises shell, wiring board and is installed on first coaxial fitting, second coaxial fitting and the 3rd joint on the shell; Said first coaxial fitting and first microstrip line join; Second microstrip line and second coaxial fitting join, and first coupling capacitance is connected between first microstrip line and second microstrip line; One end and first microstrip line of first inductance join, and the other end links to each other with first shunt capacitance, gas discharge tube, first decoupling element respectively; The other end ground connection of first shunt capacitance; One end and second microstrip line of second inductance join, and the other end links to each other with second shunt capacitance, second coupling capacitance; One end of second decoupling element with join with TVS pipe and the 3rd joint, the other end of second decoupling element joins with second coupling capacitance, first decoupling element, the other end ground connection that gas discharge tube and TVS manage.But both can find out from accompanying drawing that this radio frequency lightning protection device was not the coaxial radio-frequency lightning protection device.Therefore necessary this is improved.
