Problems solved by technology

[0010] Although this utility model also integrates a variety of connectors on a metal plate, and there is also a 75-ohm BNC type connector, and the metal plate is also fixed with screws, but this utility model is a combined lightning protection device, and its protection object is the power supply Line and video coaxial cable signals belong to the protection of wired signals, which are different from the wireless navigation radio frequency protection of the present invention in structure, principle and application
Moreover, this utility model does not have a structure in which the core tube, the connecting pin, and the main body of the coaxial discharge tube shell are sequentially connected, nor does it use flange joints and mounting holes for matching positioning

Embodiment 1

[0044] The integrated lightning protector 1 is more suitable for the case where the number of radio frequency connectors 3 required by the equipment can be determined, so that an integrated device with several mounting holes 41 can be selected according to the number of radio frequency connectors 3 required. Type lightning arrester 1. Such as figure 1 , figure 2 with Figure 5 As shown, the casing body 4 of the integrated lightning arrester 1 has a through cylindrical mounting hole 41, and there is a discharge tube insert 22 on both sides of the discharge tube 21 of the coaxial discharge tube 2, and the coaxial discharge tube 2 is installed In the middle of the installation hole 41 , each discharge tube core 22 is connected to a connecting pin 23 . The radio frequency connector 3 includes a flange plate 31 , a flange joint 32 , a radio frequency interface 33 , an insulator 34 and a core tube 35 . The core tube 35 is installed in the insulator 34 , and the insulator 34 is ...

Embodiment 2

[0053] The number of radio frequency connectors 3 required by the equipment can be determined or cannot be determined, and the modular lightning arrester 1 can be applied. Such as Image 6 , Figure 7 with Figure 8As shown, the difference from the first embodiment is that: each housing body 4 of the modular lightning arrester 1 is provided with a connecting piece, and the connecting piece includes a slot 43 and a protrusion 44 . The connector is provided with two bar-shaped bumps 44 with a T-shaped cross-section on a surface adjacent to the mounting hole 41 of the housing body 4, and on the same housing body 4, it is opposite to the bumps 44. A strip-shaped card slot 43 is provided on the upper surface. Wherein the face opposite to the bump 44 is: the face not adjacent to the bump 44 on the cuboid housing body 4 . Each shell body 4 is a module, and multiple shell bodies 4 are connected together through the cooperation of the protrusions 44 and the slots 43, and the radio ...

Embodiment 3

[0060] Embodiment 3 is substantially the same as Embodiment 2, except that the connectors on the housing body 4 of the lightning arrester 1 are removed, and the connections between multiple housing bodies are welded. In addition, during welding, the mounting holes 41 of two adjacent casing main bodies 4 can be combined into a welded lightning arrester 1 in two ways, parallel or vertical, as in the second embodiment. And when the two adjacent shell main bodies 4 of the welded lightning arrester 1 are combined, they can be aligned and combined as in Embodiment 2, or they can be staggered for welding combination, and the staggered welding is the two adjacent shell main bodies 4 Welding is carried out after translation and staggering on the contacting surfaces, for example, welding a plurality of shell main bodies 4 into a stair shape is a staggered welding method.

Abstract

Disclosed is an integrated radio frequency lightning arrester which comprises a coaxial discharging tube which comprises a discharging tube body and discharging tube inserting cores. The integrated radio frequency lightning arrester is characterized by being mainly composed of a shell body and more than two radio frequency connecting heads, the radio frequency connecting heads are integrated on the shell body by adopting an integration mode, mounting holes are formed in the shell body, two connecting needles sleeve the discharging tube inserting cores at two ends of the discharging tube body respectively and are jointly mounted in one mounting hole formed in the shell body, one radio frequency connecting head can be mounted at each of two ends of each mounting hole, and each connecting needle is connected with one radio frequency connecting head. Modules in the lightning arrester can be combined and demounted freely, combining angle of the modules can be changed, and the radio frequency connecting heads can be matched freely.

Description

technical field [0001] The invention relates to a radio frequency lightning protector for a navigation system, in particular to a radio frequency lightning protector capable of integrating more than two radio frequency connectors on the main body of the housing, and capable of arbitrarily matching various types of radio frequency connectors . Background technique [0002] Navigation satellite communication transmits wireless electromagnetic waves, and the information is received and processed by satellite ground station equipment or vehicle-mounted, airborne, and ship-borne terminal equipment. However, a large number of modern electrical equipment, electronic equipment, computer control and large-scale integrated circuits are becoming more and more integrated, smaller and smaller, and more complete in function, but the disadvantages are also becoming more prominent. A large number of sensitive electronic components are used in computer equipment and large-scale integrated c...
