The radio frequency signal of the liner signal transmission path structure is transmitted to the inner liner PCB board through the joint male seat on the shell PCB board and the PIN needle and the joint female seat. The inner liner is made of aluminum alloy. The connector male seat plays the role of grounding. The inner liner signal transmission path structure of this structure is relatively complicated, the assembly is more inconvenient, and the production cost is high; in addition, the radio frequency signal is transmitted to the inner liner PCB board through the connector male seat on the shell PCB board and the PIN needle and the connector female seat. , the distance between the shell PCB board and the liner PCB board is large, so that the volume of the liner signal transmission path structure is relatively large, and the space utilization rate is low.

The technical problem to be solved by the present invention is to overcome the above defects of the prior art, and provide a signal transmission path structure of the liner with simple structure, convenient assembly, low cost and high space utilization.

The technical solution of the present invention is to provide a liner signal transmission path structure with the following structure: it includes a shell, a shell PCB board, an inner liner, an inner liner PCB board, a connector female seat and a PIN needle, the described The housing PCB board is fixedly installed on the housing, and the inner tank is provided with a through hole for inserting the connector base, and the free end surface of the connector base is provided with a jack for inserting the PIN needle. The inner tank PCB board is fixedly installed on the inner tank, the lower end of the joint female seat is fixedly connected to the shell PCB board, the upper part of the PIN needle is connected to the inner tank PCB board, and the lower part of the PIN needle is arranged on the joint female seat. In the jack hole on the free end face, the outer wall of the joint female seat is connected with the inner wall of the through hole of the liner.

After adopting the above structure, the signal transmission path structure of the inner tank of the present invention has the following advantages compared with the prior art: in the signal transmission path structure of the inner tank, the PCB board of the inner tank is fixedly installed on the inner tank, and the lower end of the connector female seat It is fixedly connected to the shell PCB, the upper part of the PIN pin is connected to the PCB board of the liner, the lower part of the PIN pin is set in the socket on the free end surface of the connector female base, and the outer wall of the connector female base is connected to the inner tank. The inner wall of the hole is connected, because the male seat of the connector is removed, and the outer wall of the female connector is connected to the inner wall of the through hole of the liner, which plays the role of grounding the female seat of the connector. Therefore, the signal transmission path of the inner tank is simple in structure and easy to assemble. The cost is low; and the distance between the shell PCB board and the liner PCB board is shortened, thereby reducing the overall volume and improving the space utilization rate.

As a preference, a cylindrical wall is provided on both ends of the through hole of the liner, the cylindrical wall and the liner are integrally formed, and the inner diameter of the cylindrical wall is equal to the inner diameter of the through hole. The bladder PCB board is fixedly connected with the upper end surface of the cylindrical wall of the inner tank through fixing screws; the outer wall of the connector base is connected with the inner wall of the cylindrical wall. When installing the PCB board of the inner tank, it is only necessary to fix the PCB board of the inner tank on the upper end surface of the cylindrical wall with fixing screws. The installation is very convenient, and the cylindrical wall on both ends of the through hole of the liner and the inner wall of the through hole replace the male joint seat of the prior art and play a role of grounding.
