Description
Technical field
The utility model relates to a kind of microwave communication transmission apparatus, specifically a kind of for the coaxial lightning arrester in radio-frequency (RF) coaxial equipment.
Background technology
An orthogonal horizontal housing and a longitudinal housing is generally comprised for the coaxial lightning arrester in radio-frequency (RF) coaxial equipment; Arrange horizontal insulator and transverse center conductor in horizontal housing cavity, horizontal housing and transverse center conductor two ends are respectively arranged with the coaxial fitting comprising jack and contact pin structure; Be provided with the longitudinal center conductor vertical with transverse center conductor in longitudinal housing, longitudinal center's conductor is solid rod-like structure, and its lower end is connected with transverse center conductor, and upper end coordinates with longitudinal case top lid grafting.
In order to obtain preferably unit for electrical property parameters (frequency range, standing-wave ratio etc.), longitudinal center's conductor normal length is longer, makes the length of whole device longer, adds the consumption of material and taking of space.The structural strength of longer longitudinal center's conductor is lower; usually also need to arrange insulator to support longitudinal center's conductor; thus too increase manufacturing cost; even if the later stage has been designed have spiral fluted short bar; but because can not carry out longitudinal adjustment, therefore performance parameter can not adjust flexibly.
Summary of the invention
The technical problems to be solved in the utility model is to provide that a kind of not only longitudinal length is little, low cost of manufacture, reliability are high but also can conveniently to the coaxial lightning arrester that performance parameter regulates.
In order to solve the problems of the technologies described above, coaxial lightning arrester of the present utility model, include orthogonal horizontal housing and longitudinal housing, in horizontal housing, insulator and transverse center conductor are set, horizontal housing and transverse center conductor two ends arrange coaxial fitting, longitudinal center's conductor is provided with in longitudinal housing, longitudinal center's conductor lower end is connected with transverse center conductor, longitudinal center's conductor is hollow tubular structures, tube wall has inside and outside through helicla flute, internal thread is provided with in longitudinal housing, one is provided with externally threaded nut in described longitudinal housing, nut grafting in longitudinal center's conductor upper end and longitudinal housing.
The contact pin of the nut upper process in described longitudinal housing, the upper end of longitudinal center's conductor is provided with the jack matched with contact pin, the contact pin grafting of the nut upper process in longitudinal center's conductor upper end and longitudinal housing, the hole wall of jack has circumferential longitudinal slit.
The upper surface of described nut has in-line groove.
Described longitudinal housing upper end is provided with external screw thread, and longitudinal housing goes back capping outward a capping.
After adopting above-mentioned structure, adopt longitudinal center's conductor of hollow-core construction, and on tube wall, have inside and outside through helicla flute, detect through reality and prove, it is compared with traditional structure, on longitudinal center's conductor, inside and outside through space can effectively regulate the electrical property of device and improve, and can obtain with shorter longitudinal length the unit for electrical property parameters needed; Shorter longitudinal center's conductor structure stability is also better, therefore supporting without the need to arranging insulator in the middle, reducing manufacturing cost; In addition, due to through inside and outside the helicla flute on longitudinal center's conductor, whole longitudinal center conductor is made to have certain elasticity in the axial direction, therefore when the contact pin grafting of the nut projection in its upper end and longitudinal housing, certain contact can be kept, improve the reliability of connection, facilitate and performance parameter is regulated.
