Embodiment
The utility model embodiment solution mainly is: the frequency band that adopts 0-6GHZ; And the support housing that connects and support inner and outer conductor and the outer conductor of lightning arrester are directly through being threaded; Not only simple in structure, and applicable band is wide, makes that the signal transmission performance of lightning arrester is good; Thunder and lightning circulation capacity is big, and the insertion loss is low.
In the prior art, the antenna-feedback system at antenna feeder arrester place is meant the equipment of transmitting radio frequency signal between machine top and the antenna of NodeB rack.The structure of this antenna-feedback system comprises: antenna, lightning arrester, wire jumper, feeder line, feeder line earth clip, feeder window and tower amplifier etc.Wherein, Antenna feeder arrester is a kind of as Surge Protector; It mainly is the lightning protection of taking to the feeder line in the antenna-feedback system; Antenna feeder arrester is connected between the electronic equipments such as antenna system and transceiver, because of feeder line indirect lightning strike overvoltage antenna system and transceiver is caused damage in order to preventing.Antenna feeder arrester is claimed antenna feeder siganl thunder-proof device, antenna feeder arrester, antenna feeder circuit lightning protection device, antenna feeder leakage conductor etc. again; Its lightning-arrest basic principle is: useful signal and lightning wave are separated; And the thunder and lightning path of lightning current through lightning arrester is incorporated into ground, thereby reach the purpose of protective circuit and electronic equipment.
Because the fault of construction of existing antenna feeder arrester, make existing antenna feeder arrester complex structure, and narrower because of frequency of utilization, can't satisfy the requirement of communication signal parameters transmission.
Like Fig. 1, Fig. 2 and shown in Figure 3; A kind of ultra broadband antenna feeder arrester that present embodiment proposes; Comprise outer conductor 1, be positioned at outer conductor 1 and the inner wire 2 coaxial with outer conductor 1; And with the axial perpendicular columnar support housing 3 of inner and outer conductor 2,1, the frequency of utilization of the lightning arrester of present embodiment is 0-6GHZ, the frequency of utilization scope of this ultra broadband can satisfy the user demand of multiple frequency range electronic equipment.
In addition, an end that is used for the support housing 3 of support fixation inner and outer conductor 2,1 directly is fixedly connected with the sidewall 12 of outer conductor 1 through screw thread, has simplified the structure of lightning arrester thus, provides cost savings.
Particularly, the two ends of antenna feeder arrester are blank area, and the one of which end connects electronic equipments such as transceiver; The other end connects antenna system; Wherein, the end that inner wire 2 connects electronic equipment is the male joint 21 with contact pin structure, and an end that connects antenna is the female joint 22 with jack structure.The structure of the inner wire 2 in the present embodiment is as shown in Figure 5.
Lightning arrester is inner realizes sealing in order to make, and present embodiment is filled with teflon insulation medium 4 between inner wire 2 and outer conductor 1 and in the inboard of the blank area of lightning arrester.
Like Fig. 1 and shown in Figure 4; The middle part of outer conductor 1 is a square body 11, and a sidewall 12 of this square body 11 is provided with internal thread hole 13, and the end that support housing 3 is connected with outer conductor 1 is provided with the external screw thread 31 that cooperates with above-mentioned internal thread hole 13; As shown in Figure 6; Support housing 3 middle parts are provided with ring-shaped step 32, and after the end that support housing 3 is provided with external screw thread 31 screwed in the internal thread hole 13 on square body 11 sidewalls 12, the end face of the ring-shaped step 32 at support housing 3 middle parts was pressed in sidewall 12 surfaces of square body 11.
