Abstract
The utility model discloses a waterproof high stability passive component, including cavity, apron and briquetting, interference fit between briquetting and the cavity, the up end of briquetting is located same horizontal plane with the up end of cavity outer lane portion, and is provided with the installation through -hole on the briquetting, be provided with the installation lug on lieing in bottom end in the cavity, the up end and the lower terminal surface of briquetting of installation lug are closely laminated, are provided with the screw hole on the installation lug, and connecting bolt passes the installation through -hole on the briquetting and installs the screw hole of lug, with briquetting and cavity fixed connection. The utility model discloses a briquetting and the complete block of cavity, and the apron sets up waterproof ring of recess with the complete closing cap of the up end of briquetting and cavity on the apron, can effectually prevent the outer dust of device, and the briquetting further is connected through connecting bolt with the cavity, makes connection structure between them more stable, the stability of assurance device has improved the third order intermodulation index of device.
Description
Technical field
The utility model relates to the passive device used in the microwave technical field such as communication, radar, specifically a kind of waterproof high stability passive device.
Background technology
Coupler and electric bridge distribute in specific proportions for microwave signal or synthesize power, is one of element the most frequently used in microwave technical field.In most cases, passive device is all be applied in indoor, but be applied in outdoor words, structure must be improved, but the electrical specifications of passive device and third order intermodulation index very strict to the dimensional requirement of device, structure is bad, has influence on electrical specifications and the third order intermodulation index of device possibly.Affect the performance of device.The length of the cover plate pressing part of existing passive device and wide, correspond to the length of cavity inside groove and wide, cavity wall has a circle capillary groove, in product installation process, after interiors of products debugging terminates, in capillary groove, place the moderate cross section of radius is circular water proof rubber circle, then covers cover plate, and cover plate and cavity are passed through screw compact siro spinning technology.Cavity can be made like this to be sealing state, due to the elastic reaction of rubber ring, to add the close contact of upper cover plate and cavity, can effectively prevent entering of external object, thus inside cavity and external environment come.And then reach the effect of waterproof.But this structure also also exists following shortcoming: 1, because the wall between the position of capillary groove and space inner chamber can be too thin, current processing conditions is limited, is difficult to accomplish accurate size, brings very big inconvenience to machining; If 2 amplify and increase cost, and integral type cover plate is because the necessary loose fit of debugging reason, is easy to cause leakage signal and affect index of correlation.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of waterproof high stability passive device, its good water-proof effect, and is connected and fixed Stability Analysis of Structures, and processing is installed simple and convenient.
The technical solution of the utility model is:
Waterproof high stability passive device, includes cavity and cover plate, and the upper surface of described cavity is cascaded surface, and the upper surface in its outer ring portion, higher than the upper surface in inner ring portion, has additional briquetting between described cavity and cover plate; Interference fit between described briquetting and cavity, the upper surface of briquetting and the upper surface in cavity outer ring portion are positioned at same level, and briquetting are provided with bolt installation through hole; Be positioned in described cavity on bottom end face and be provided with installation projection, the installation upper surface of projection and the lower surface of briquetting fit tightly, install on projection and be provided with screwed hole, connecting bolt is installed through hole through the bolt on briquetting and is installed the screwed hole of projection, is fixedly connected with by briquetting with cavity.
The lower surface of described cover plate and the upper surface in cavity outer ring portion, the upper surface of briquetting fit tightly, and the lower surface of cover plate is provided with a circle capillary groove, is provided with water proof rubber circle in capillary groove, and the upper surface in water proof rubber circle and cavity outer ring portion fits tightly.
Advantage of the present utility model:
Briquetting of the present utility model engages completely with cavity, and cover plate is by the complete capping in upper surface of briquetting and cavity, effectively can prevent the dust outside device, moisture content etc. enter into the inside of cavity, the water proof rubber circle arranged, more can stop the infiltration of liquid etc., water resistance can reach IP67 grade; And briquetting is connected further by connecting bolt with cavity, make both syndetons more stable, ensure the stability of device, improve the third order intermodulation index of device, recycle cover plate simultaneously and fix briquetting and cavity, while ensureing device sealing, further increase the third order intermodulation index of device.
