Detailed Description

In order to illustrate the invention more clearly, the invention is further described below with reference to preferred embodiments. It is to be understood by persons skilled in the art that the following detailed description is illustrative and not restrictive, and is not to be taken as limiting the scope of the invention.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as being fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood as appropriate by those of ordinary skill in the art.

At present, the fixing means of PCB antenna in the rod-shaped antenna need be with the help of auxiliary component such as end stopper, PU bubble cotton, and the part kind of use is more, still can consume the more man-hour of operating personnel when the end stopper is assembled and dress PU bubble is cotton moreover, and the installation is inconvenient.

To solve the technical problem, an embodiment of the present invention provides an improved ONT rod antenna, which basically has the same structure as the existing antenna, as shown in fig. 1 to 4, and the main components include a rod cover 1, a PCB antenna 2 and a connector 3, the PCB antenna is generally designed in a flat shape, and can withstand bending at a small angle.

In this embodiment, the sleeve 1 is formed with an opening 11 at one end and a chamber formed therein, which extends from the upper portion of the sleeve to the lower portion along the length of the sleeve and communicates with the opening, and the connector 3 is detachably connected to the opening 11 of the sleeve 1, and the connector is a standard part of an antenna and is self-selectable.

Importantly, the main improvements of the present application over the prior art are: the PCB antenna sets up the cavity of installing at the rod cover equally, but this application is provided with spacing muscle structure in the cavity of rod cover, restricts the removal of X direction, Y direction and the Z direction of PCB antenna through the cooperation of spacing muscle structure to reach the purpose of fixed PCB antenna.

In detail, regarding the design of the spacing ribs: the limiting rib structure comprises three limiting ribs 12 distributed in a shape like a Chinese character 'shan', namely, two limiting ribs 12 are arranged on the same side and are separated from each other, the third limiting rib 12 is arranged in the middle position of the two opposite sides of the limiting ribs, the three limiting ribs 12 are all connected to the inner wall of the rod sleeve 1, the exposed surface of each limiting rib 12 is designed to be a flat contact plane, the surface of the PCB antenna 2 is prevented from being scratched in assembly, a space is reserved between the two limiting ribs 12 on one side of the same position and the limiting rib 12 on the other side, and the PCB antenna 2 is clamped between the two limiting ribs 12 on one side of the same position and the limiting rib 12 on the other side in assembly.

It is worth noting that the distance between the two limiting ribs on the same side and the limiting rib on the other side is slightly smaller than the thickness of the PCB antenna, so that when the PCB antenna is slowly inserted into the distance between the two limiting ribs on the same side and the limiting rib on the other side, the PCB antenna is forced to be slightly bent and form a C shape by the three limiting ribs arranged in a herringbone shape, each limiting rib is in extrusion contact with the PCB antenna, and therefore the movement of the PCB antenna in the X, Y and Z directions is locked through the static friction force between the three limiting ribs and the surface of the PCB antenna, and the fixing of the PCB antenna is achieved.

Compare in the means of the cotton fixed PCB antenna of end stopper and PU bubble in the tradition, with the help of the spacing muscle structure that three spacing ribs constitute can quick effectual fixed PCB antenna to the auxiliary part demand is few, cost reduction.
