This shield assemblies comprises the first half radome 71A and the second half radome 90A.Jut 120 and 121 is located on the edge of the sidewall sections 75A of the first half radome 71A and 76A.Recessed portion 120 and 121 has the cross section that shape resembles a part of circle.
Trench portions 122 and 123 is formed on the edge of the sidewall sections 95A of the second half radome 90A and 96A.These trench portions 122 and 123 have the cross section that shape resembles a part of circle, and it can be clipped together with jut 120 and 121.
In the first half radome 71A and the second half radome 90A state of contact, the edge of sidewall sections 75A and 76A and sidewall sections 95A and 96A is faced together.Outside, jut 120 and 121 and trench portions 122 and 123 clip together and push them.Therefore, between the first half radome 71A and the second half radome 90A, can not form " electric gap ".
If jut 120 and 121 and trench portions 122 and 123 between have the vulnerable area of pushing mutually, then can locally form the gap.But in this embodiment, the gap does not form with respect to X1-X2 direction linearity to be passed through, because jut 120 is clipped together with trench portions 122 and jut 121 is clipped together with trench portions 123.Therefore, the gap is blocked by jut 120 and 121, thereby can not form " electric gap " between the first half radome 71A and the second half radome 90A.
Figure 13 demonstrates the shield assemblies 70B as the embodiment of second distortion.
In this embodiment, adopting denation partly to replace the cross section of above-mentioned embodiment is the jut of a part of circle shape.
Shield assemblies comprises the first half radome 71B and the second half radome 90B.
The first half radome 71B comprise sidewall sections 75B and 76B.Sidewall sections 75B and the 76B of first half radome 71B comprise that the transverse shape that is positioned on the edge is a part of leg-of-mutton jut 130 and 131.
The second half radome 90B comprise sidewall sections 95B and 96B.The sidewall sections 95B of the second half radome 90B and 96B comprise that its part cross section has the triangular shaped trench portions 132 and 133 that can clip together with the jut 130 and 131 on the edge.
In the first half radome 71B and the second half radome 90B state of contact, the edge of sidewall sections 75B and 76B and sidewall sections 95B and 96B is faced mutually.Outside, jut 130 and 131 and trench portions 132 and 133 clip together and push them.Therefore, between the first half radome 71B and the second half radome 90B, can not form " electric gap ".
If jut 130 and 131 and trench portions 132 and 133 between have the vulnerable area of pushing mutually, then can locally form the gap.But in this embodiment, the gap does not form with respect to X1-X2 direction linearity to be passed through, because jut 130 is clipped together with trench portions 132 and jut 131 is clipped together with trench portions 133.Therefore, the gap is blocked by jut 130 and 131, thereby can not form " electric gap " between the first half radome 71B and the second half radome 90B.
With respect to above-mentioned sidewall sections 75B, 76B, 95B and 96B, jut and trench portions are formed on the edge center of sidewall sections.Therefore, the width t2 of sidewall sections 75B, 76B, 95B and 96B is than shorter at the width t1 of the sidewall sections shown in Fig. 8 75,76,95 and 96.
The present invention is not limited to these embodiments, but can make various changes and improvements without departing from the scope of the invention.
