Embodiment
Refer to Fig. 1, Fig. 2 and Fig. 3, radome of the present invention (figure is mark not) removably is installed on the circuit board 50 in an electronic installation (not shown), and this circuit board 50 is roughly rectangular tabular, is laid with at least one electronic devices and components 52 on it.Described radome comprises a cover body 30 and two cover body fixed parts 55.Described cover body 30 is rectangular cover body shape roughly, and it is with together with described two cover body fixed parts 55 removably are installed in and cover on the electronic devices and components 52 on circuit board 50.
Described cover body 30 comprises a roof 31 and the vertical perisporium 35 that extends the essentially rectangular frame shaped be bent to form of a periphery by this roof 31.Connect and offer some through holes 312 on described roof 31.Described perisporium 35 comprises two sidewalls that relatively be arranged in parallel 352, relatively convexes with respectively at least one holding section 355 on the inwall of this two sidewall 352.In the present embodiment, convex with to adjacent spaces respectively roughly cylindrical projection shape of two 355，Gai holding sections, holding section 355 on described two sidewalls 352.
Described two cover body fixed parts 55 are roughly rectangular tabular, and it is along being fixed on circuit board 50 perpendicular to these circuit board 50 directions and being positioned at the relative both sides of described electronic devices and components 52, with for installing described cover body 30.Relatively connect and offer at least one engaging chute 57 respectively corresponding to the holding section 355 on two sidewalls 352 of described cover body 30 on described two cover body fixed parts 55, this engaging chute 57 roughly is " L " type, and it comprises that one snaps in end 571, one slippage slot 573 and a holding section 575.The described end 571 that snaps in is that an edge connects perpendicular to these circuit board 50 directions the strip gab that this cover body fixed part 55 is offered away from a lateral margin of this circuit board 50, so that described cover body 30 is while being installed on described cover body fixed part 55, the holding section 355 on this cover body 30 snaps in from the described end 571 that snaps in accordingly.Described slippage slot 573 is rectangular strip roughly, itself and this snap in end 571 and be interconnected and be opened on this cover body fixed part 55 along being parallel to circuit board 50 directions.Described holding section 575 is an elastic clamping block, it is convexly set in the close terminal position place in described slippage slot 573, it is fastened in this slippage slot 572 for the holding section 355 by described cover body 30, to prevent that in the electronic installation use procedure, holding section 355Yu holding section 474 breaks away from and causes the relative slippage slot 572 of cover body 30 to slide.
See also Fig. 4, when described radome is installed, first by described two cover body fixed part 55 opposing parallel be fixed at the both sides of the electronic devices and components 52 on described circuit board 50, between this two cover bodies fixed part 55, between two sidewalls 352 of the distance at interval and described cover body 30, the distance at interval is quite.Next, described cover body 30 is covered in to electronic devices and components 52 tops on described circuit board 50, make holding section 355 on two sidewalls 352 of this cover body 30 respectively the engaging chute 57 on two cover body fixed parts 55 on alignment circuit plate 50 snap in end 571.Again next, push against described cover body 30 downwards, make the holding section 355 on this cover body 30 snap onto accordingly snapping in end 571 of this engaging chute 57.Finally, promote described cover body 30 along being parallel to these circuit board 50 directions, make the holding section 355 on two sidewalls 352 of this cover body 30 face subterminal holding section 575 along slippage slot 573 slippages of the engaging chute 57 on described two cover body fixed parts 55 until described slippage slot 573 is crossed in this holding section 355 respectively, together with now described cover body 30 and described cover body fixed part 55 interfix and be installed in, complete the installation of described radome.
Described radome is by be respectively provided to a few holding section 355 on two of its cover body 30 relatively parallel sidewalls 352, thereby removably is installed on circuit board 50 by this cover body 30 and covers at each electronic devices and components 52 tops on circuit board 50.Described radome 30 is simple in structure, convenient disassembly, can reuse.
Be appreciated that described two cover body fixed parts 55 also can directly be arranged on circuit board 50 and be positioned at the position, relative both sides of the electronic devices and components 52 on this circuit board 50.
Be appreciated that described two cover body fixed parts 55 can be also the two stripe shape slots that relatively are arranged with electronic devices and components 52 both sides on this circuit board 50.
In addition, those skilled in the art also can make various modifications, interpolation and the replacement on other forms and details in the claims in the present invention scope of disclosure and spirit.Certainly, the variations such as various modifications, interpolation and replacement that these are made according to spirit of the present invention, within all should being included in the present invention's scope required for protection.
