Description
Technical field
The utility model belongs to microwave communication device, relate to a kind of be used for radio-frequency (RF) coaxial equipment coaxial lightning arrester.
Background technology
The coaxial lightning arrester that is used for radio-frequency (RF) coaxial equipment has generally comprised an orthogonal horizontal housing and a vertical housing.Laterally in the housing inner chamber horizontal insulator and transverse center conductor are set, laterally housing and transverse center conductor two ends are respectively arranged with and are full of the coaxial fitting that jack or contact pin structure are arranged; Vertically be provided with the longitudinal center conductor vertical with the transverse center conductor in the housing, longitudinal center's conductor is the solid rod-like structure, and its lower end is connected with the transverse center conductor, pegs graft with vertical case top lid and cooperate in the upper end.In order to obtain preferable unit for electrical property parameters (frequency range, standing-wave ratio etc.), longitudinal center's conductor normal length is longer, makes the length of entire device longer, has increased the consumption of material and taking of space.The structural strength of long longitudinal center's conductor is lower, needs also that usually insulator is set longitudinal center's conductor is supported, thereby also increased manufacturing cost.In addition, longitudinal center leads with the rigidity of case top lid and pegs graft, and the reliability of its connection also is difficult for guaranteeing.
Summary of the invention
Technical problem to be solved in the utility model is, provides that a kind of longitudinal length is little, unit for electrical property parameters good, low cost of manufacture, coaxial lightning arrester that reliability is high.
Coaxial lightning arrester of the present utility model includes orthogonal horizontal housing and vertical housing, laterally in the housing insulator and transverse center conductor are set, laterally housing and transverse center conductor two ends are provided with coaxial fitting, vertically be provided with longitudinal center's conductor in the housing, longitudinal center conductor lower end is connected with the transverse center conductor, longitudinal center conductor upper end and the vertically loam cake grafting of housing, it is characterized in that: described longitudinal center conductor is a hollow tubular structures, has the inside and outside helicla flute that connects on tube wall.
The loam cake inboard of described vertical housing is provided with the contact pin of projection, and simultaneously the upper end of longitudinal center's conductor is provided with the jack that matches with contact pin, is having the circumferential vertical slit that connects inside and outside several on the hole wall of jack.
The utility model adopts longitudinal center's conductor of hollow-core construction, and the helicla flute that inside and outside tube wall has, connects, prove through actual detected, it is compared with traditional structure, the space of inside and outside perforation can effectively be regulated and improves the electrical property of device on longitudinal center's conductor, and can obtain the unit for electrical property parameters that needs with short longitudinal length; The structural stability of short longitudinal center's conductor is also better, therefore need not that insulator is set in the middle and supports, and has reduced manufacturing cost; In addition, owing to connect inside and outside the helicla flute on longitudinal center's conductor, make whole longitudinal center conductor have certain elasticity in the axial direction, therefore when peg graft with the loam cake of vertical housing in its upper end, can keep certain contact pressure, improve the reliability that connects.
