Detailed Description

To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Generally, when a circuit layer of an existing feed network body is welded with a feed cable, a core wire of the feed cable is often higher than a plane where the circuit layer of the feed network body is located, so that a gap exists between the core wire and the plane, an electric field discontinuity phenomenon occurs at a port of the feed network body, and impedance matching is further deteriorated.

For easy understanding, fig. 1 shows a schematic view of an assembly effect of a conventional feed network port cable, and as shown in fig. 1, core wire pads 1-2 and shielding layer pads 1-3 for respectively welding a core wire 4-1 and a shielding layer 4-2 of a feed cable 4 are provided at a port 1-1-0 of a line layer 1-1 of a conventional feed network body. Obviously, the core wire 4-1 of the feed cable is higher than the plane where the line layer 1-1 of the feed network body 1 is located, a gap exists between the core wire 4-1 and the plane, when welding, the core wire 4-1 of the feed cable needs to be pressed downwards to be lapped on the corresponding core wire bonding pad 1-2, and the lower surface of the shielding layer 4-2 of the feed cable is tangent to the corresponding shielding layer bonding pad 1-3. Therefore, the electric field at the port 1-1-0 has obvious discontinuity, which causes the impedance matching to deteriorate, thereby causing the standing wave of the input port of the feed network to increase, the loss to increase, and the communication quality to be seriously affected.

Based on this, the feed network device and the feed network system provided by the embodiments of the present invention can effectively alleviate the above technical problems.

For the convenience of understanding the embodiment, a detailed description will be first given of a feeding network apparatus disclosed in the embodiment of the present invention.

Therefore, the feed network device provided by the embodiment of the invention comprises a feed network main body and a structural component, wherein the structural component further comprises a layered structural component in the vertical direction and a port structural component in the horizontal direction; the feed network main body is fixed on the surface of the layered structure assembly, the port structure assembly is fixed at a port of the feed network main body and is used for fixedly connecting the feed network main body and the layered structure assembly, a first notch for welding a feed cable is further arranged at the port of the feed network main body, and a second notch is arranged at the position of the layered structure assembly, which is the same as the first notch in horizontal position; the first notch and the second notch are matched, so that a core wire of the feed cable can be lapped on a core wire bonding pad on a circuit layer of the feed network main body, the feed network main body and the feed cable are concentrically and continuously butted, an electric field at a welding position is continuous, the problems that the impedance matching of the feed network main body is deteriorated and the standing wave bandwidth is reduced due to the electric field discontinuity are solved, and the communication quality is improved.

In practical use, in order to facilitate welding of the feed network main body and the feed cable, a port of the feed network main body is generally provided with a pad, and specifically, the feed network main body provided in the embodiment of the present invention, because the first notch and the second notch are matched to enable a core wire of the feed cable to be lapped on a core wire pad on a circuit layer of the feed network main body, the pad of the feed network main body in the embodiment of the present invention is also generally matched with the first notch and the second notch, so as to ensure that the core wire of the feed cable is lapped on the core wire pad on the circuit layer of the feed network main body after assembly, specifically, the circuit layer of the feed network main body is respectively provided with a first pad connected with a shielding layer of the feed cable and a second pad connected with the core wire of the feed cable at a position corresponding to the first notch; that is, the first pad is a shield layer pad for soldering a shield layer, and the second pad is a core wire pad for soldering a core wire.

Obviously, the first notch at the input/output port of the feed network body can enable the core wire of the feed cable to be exactly flush with the circuit layer of the feed network body, so that the phenomena of impedance matching deterioration and standing wave bandwidth reduction of the feed network body caused by electric field discontinuity generated by the structure that the shielding layer of the feed cable is flush with the circuit layer of the feed network body in fig. 1 can be obviously improved. In addition, because the shielding layer pad of the feed network main body, namely the ground through hole is arranged beside the first pad, and the surface of the circuit layer in the area where the ground through hole is located is coated with green oil, the first pad can be electrically connected with the ground wire corresponding to the back surface of the first pad, the potential difference is zero, tin current at the first pad can be isolated, and the feed network is prevented from being perceived difficultly and being eliminated intermodulation hidden trouble caused by the fact that the tin current enters the ground through hole.
