Example Embodiment

[0025] The present invention will now be further described in conjunction with the embodiments and drawings:

[0026] Attach the radome 1 (see figure 2 ) Designed as a composite structure composed of a mouth frame 6 and a cover body 7. The mouth frame 6 is made of aluminum alloy, and the cover body 7 is made of glass fiber cloth. The mouth frame 6 and the cover body 7 are bonded by epoxy resin. An annular groove A is designed on the outside of the embedded section of the mouth frame 6 to make the mouth frame 6 and the cover body A multi-level waterproof edge is formed between 7 and at the same time the bonding strength between the mouth frame 6 and the cover 7 is increased.

[0027] In the radome mouth frame 6 (see figure 2 A ring boss E is designed on the inner side of ), and an O-ring 3 mounting groove G is designed on the end face F of the ring boss of the radome, and the O-ring 3 is pasted in the mounting groove G. At the same time in the cabin end frame 2 (see image 3 ) An a

Abstract

The invention relates to a seal structure for sleeve connection of a pod body and an antenna housing of an onboard electronic pod. The seal structure comprises an onboard electronic pod antenna housing and an onboard electronic pod body end frame and is characterized in that an opening frame is arranged at the opening end of the housing body of the onboard electronic pod antenna housing, an annular groove is formed in the outer side of the embedding section where the opening frame is connected with the housing body, and the annular groove is bonded to the housing body through epoxy resin. An annular boss is arranged on the inner side of the opening frame, an installation groove is formed in the end face of the annular boss, and an O-shaped sealing ring is bonded to the inside of the installation groove. An annular boss is arranged on the inner side of a port of the onboard electronic pod body end frame, and the end face of the annular boss and the outer end face of the pod body end frame are coplanar. The pod body end frame is sleeved in the opening frame, and the end face of the annular boss and the annular boss end face of the pod body end frame are bonded by means of screw fastening. The seal structure for sleeve connection of the pod body and the antenna housing of the onboard electronic pod can be applied to the fields of military and civil products which are free of flange connection in appearance, can only be in sleeve connection and are good in sealing and waterproof effects.
