Description

A kind of radome of electronic module

Technical field

The utility model relates to a kind of radome, is specifically related to a kind of radome of electronic module.

Background technology

At present, the radome of selling on the market 1 ', as shown in Figure 1, generally be that Milling Process goes out some cavitys 2 ' and forms on the aluminium ingot of monoblock, its each cavity can be corresponding one independently need the circuit unit that shields, so designing requirement is accurate, milling technology requires difficulty big, material and processing cost are than higher, and for example, only the radome of a 150*200mm just needs thousands of yuans.

Above-mentioned radome is to increase with the aluminium ingot milling of monoblock to form, and framework is an one, and area is bigger, and do not have solder side preferably on the circuit module, be welded in and compare difficulty on the circuit board, if be connected with circuit module by many screws 3 ', the cooperation place is too many, is difficult for installing.

In addition, need pull down whole radome when adjusting circuit board, install after regulating again, this makes troubles for follow-up maintenance.

The utility model content

The purpose of this utility model is to improve the shortcoming of prior art and radome that a kind of electronic module is provided, and this radome is easily processed, and cost is low, and shield effectiveness is good, simple installation.

For achieving the above object, the utility model adopts following technical scheme:

A kind of radome of electronic module, comprise at least one shield unit, this shield unit is made up of metal tape radome frame that is bent into and the shielding cover cap that matches, the radome of described shield unit covers and is provided with the flange that plugs together with the radome frame, the bottom of radome frame sidewall be provided with electronic module on the leg of the welding hole coupling that is provided with.

Described shielding cover cap flange is provided with projection, and described radome frame sidewall is provided with described projection and fits in the groove that elasticity is buckled.

The top of described radome frame sidewall is provided with tab, and described radome covers the jack that is provided with described tab coupling, and this tab passes the jack bending and closes with the radome cover lock.

Described radome frame is bent into two shielding cavitys by metal tape.

The metal tape of described composition radome frame is bent into serpentine, two openends of serpentine metal tape are provided with tab, the sidewall that is connected with described two openends is provided with the jack with described tab coupling, and described tab inserts in the corresponding jack respectively and bends with sidewall sealed.

The metal tape of described composition radome frame is bent into " 6 " shape, openend and another openend of middle transverse arm are equipped with tab, be respectively equipped with the jack that mates with described tab on the described two openend corresponding side walls, it is sealed with sidewall that this tab passes the jack bending.

The utlity model has following advantage:

1) the radome frame that is bent into by metal tape of the utility model is easy to process, and material is selected wide, and material and processing cost are low.

2) the shielding cover cap of the utility model shield unit removably connects, and only need dismantle screening cover when adjusting circuit, brings convenience for follow-up maintenance.

3) the radome frame that is bent into by metal tape of the utility model, its wall is thin, can splice a plurality of shield unit according to actual conditions, and each shield unit can according to circumstances be set to different shapes, only need take corresponding shield unit apart during follow-up the maintenance and get final product easy accessibility.

4) shielding cover cap of the present utility model and radome frame improve the tightness of radome by elasticity is set buckles or tab closely cooperating, and shield effectiveness is good.

5) the utility model is easily processed, cost is low, easy to install.
