Description
Technical field
The utility model relates to lightning arrester.
Background technology
Lightning arrester mainly is mainly used among the microwave signal transmission system, prevents lightening pulse electric current defective communication equipment.Thunder and lightning is the formidable enemy of electronic equipment, and thunder and lightning not only can cause the electronic devices and components operation unstable, and shorten useful life, even some parts is burnt.At present, the lightning arrester that is used for radio-frequency communication product mainly is to form by the copper alloy Milling Process, and difficulty of processing is high, and cost is high, and the frequency of utilization narrow bandwidth can not satisfy the HF communication requirement.
The utility model content
Technical problem to be solved:
Existing operating frequency is that the structure difficulty of processing of lightning arrester of 800-2500MHZ is high, and cost is high.
Technical scheme:
In order to solve above deficiency, it is the lightning arrester of 800-2500MHz that the utility model provides a kind of operating frequency, comprise main cavity 1, it is characterized in that: main cavity 1 interior both sides are left insulator 3 and right insulator 4, and right connector 5 and left connector 6 are arranged in the main cavity 1, and right left insulator 4, left insulator 3 connect respectively, the centre of main cavity 1 is inner wire 2, spirality short-circuit rods 7 is arranged on the inner wire 2, and outer tube 8 is arranged on main cavity 1 top, and pipe cap 9 is connected with outer tube and is connected fitted seal.
Main cavity 1 is one-step die casting.
Right connector and left connector are the N-type connector.
Right connector 5 and left connector 6 are packed in the mode that is press-fitted in the main cavity 1.
Beneficial effect:
Main cavity is the section bar that a die casting forms, and lightweight, processing cost is low; Voltage standing wave ratio is little, assembles simple and dependable performance, and air-tightness is good.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Come by reference to the accompanying drawings the utility model is elaborated.
As shown in Figure 1, the operating frequency that the utility model provides is the lightning arrester of 800-2500MHz, main cavity 1 interior both sides are left insulator 3 and right insulator 4, right connector 5 and left connector 6 are arranged in the main cavity 1, right left insulator 4, left insulator 3 connect respectively, and the centre of main cavity 1 is inner wire 2, and spirality short-circuit rods 7 is arranged on the inner wire 2, outer tube 8 is arranged on main cavity 1 top, and pipe cap 9 is connected with outer tube and is connected fitted seal.Briefly main cavity 1 both sides assemblings insulator and connector, inner wire is loaded onto in the centre, upper end pack into short-circuit rods, outer tube and the sleeve cap of helical structure.Simple in structure, easy to process.
Main cavity 1 is one-step die casting, just can use through simple processing.
The operating frequency of this kind structure is that the lightning arrester of 800-2500MHZ is lightweight, and processing cost is low; Voltage standing wave ratio is little, assembles simple and dependable performance, and air-tightness is good, has solved existing lightning arrester difficulty of processing high, the problem that cost is high.
