Detailed Description
The principles and features of the present invention are described below with reference to the drawings, the examples are illustrated for the purpose of illustrating the invention and are not to be construed as limiting the scope of the invention.
Referring to fig. 1 to 4, the present embodiment provides an antenna cable housing structure for solving the problem that the existing radome adopts a whole circle of plastic material for the cable baffle plate to be connected with the radome made of aluminum alloy material, so that the connection is not firm and the radome is easy to loosen.
The antenna cable housing structure of the present embodiment includes: the cable shield 20, the cable shield 30, and the cable lead-in member 40 are made of the same material as the radome 10, and the cable shield 20, the cable shield 30, and the cable lead-in member 40 are made of the same material. The cable baffle 20 is located at the side wall of the radome 10 where the cable introduction member 40 is provided and is connected with the inner bottom wall of the radome 10; the wire blocking cover plate 30 is located in a radial direction of the inner bottom wall of the radome 10 and one end of the wire blocking cover plate 30 corresponds to the wire blocking plate 20; the cable introduction 40 serves to fix the external connector and the cable barrier 20 and introduce the external connector cable into the inside of the radome 10.
In the present embodiment, the radome 10, the cable baffle 20, the cable baffle plate 30 and the cable guide member 40 are made of materials with high strength, good thermal conductivity and light weight, including but not limited to metal materials such as aluminum alloy, composite materials such as fiber metal laminate, preferably glass fiber aluminum alloy laminate. Because the materials of the radome 10, the cable baffle 20 and the wire blocking cover plate 30 are consistent, when the cable baffle 20 and the wire blocking cover plate 30 are connected with the radome 10, the cable baffle 20, the wire blocking cover plate 30 and the radome 10 are not easy to loosen.
Preferably, the cable lead-in 40 is part of the radome 10, and the cable lead-in 40 can be manufactured by the radome 10 or can be integrally formed with the radome 10.
The cable baffle 20 is of an open structure, is of a strip-shaped tetrahedron structure as a whole, is hollow in the interior, faces the cable introduction piece 40 and faces the inner bottom wall of the radome 10, namely, the top side wall, the inner side wall 23 and the end walls 24 are all of the open structure, and the outer side wall 21 and the bottom side wall 22 are of the missing structure, so that the geometric shape of the outer side wall 21 of the cable baffle 20 is matched with the geometric shape of the inner side wall of the radome 10, and the geometric shape of the bottom side wall 22 of the cable baffle 20 is matched with the geometric shape of the inner bottom wall of the radome 10. For example, when the inner side wall of the radome 10 corresponding to the cable introduction position is circular arc-shaped, the geometric shape of the outer side wall 21 of the cable baffle 20 is also circular arc-shaped, and when the inner bottom wall of the radome 10 is planar, the geometric shape of the bottom side wall 22 of the cable baffle 20 is also planar.

It should be noted that, the fixing of the cable baffle 20 to the inner bottom wall of the radome 10 is more convenient for processing and installation than the fixing method in which the cable baffle 20 is connected to the side wall of the radome 10 by providing a screw hole on the side wall of the radome 10.
In a fixed position corresponding to the external connector, a cable introduction member 40 is provided at a side wall of the radome 10, the cable introduction member 40 includes a plurality of spaced cable introduction ports 11 for the cable introduction of the external connector, each cable introduction port 11 includes a through hole 19 for the introduction of the external cable, and projections 13 located at both sides of the through hole 19, and these projections 13 extend from an inner bottom wall of the radome 10.

In other words, if the top side wall fixing position of the cable shutter 20 is selected from other positions, for example, the middle position, of the cable introduction piece 40, in order to ensure that the screw hole is opened in the boss 13, it is necessary to increase the height and width of the boss 13, and the middle position of the cable introduction piece 40 is a main position leading to the cable cover plate 30, so that the cable routing space becomes extremely strained.

The length of the cable baffle 20 is determined by covering all cable introduction interfaces 11, and compared with the cable baffle adopting a whole circle of plastic material for the existing radome, the cable baffle 20 of the embodiment is changed from full shielding to partial shielding, thereby saving the material cost and expanding the design space.
