Problems solved by technology

However, since the grounding block 103 has been screwed into an integral body with the connector 102, and the cable has been installed on the duplexer by the connector 102, and the length of the cable is limited, the movement of the grounding block 103 is restricted. The grounding block 103 can only move a short distance due to the length of the cable, and it is not convenient to disassemble the PCB cover 105. Therefore, it is urgent to optimize the structure of the duplexer

Embodiment Construction

[0029] The embodiment of the present application provides a duplexer, which is used to facilitate the removal of the PCB cover when debugging the inner cavity index of the duplexer and the PCBA coupling index of the circuit board.

[0030] see figure 2 , an embodiment of the duplexer in the embodiment of the present application includes:

[0031] Connector 203, cavity 204, grounding block 202, PCB cover 205, circuit board PCBA (not shown in the figure);

[0032] The circuit board PCBA is arranged in the cavity 204;

[0033] The connector 203 is fixedly connected to the cavity 204, and the connector 203 is connected to the parts in the cavity 204 through cables;

[0034] The PCB cover plate 205 covers the circuit board PCBA;

[0035] The grounding block 202 is connected to the cavity 204, and the grounding block 202 is provided with a through hole 206. The aperture of the through hole 206 of the grounding block 202 is larger than the outer diameter of the end of the connect...

Abstract

The embodiment of the invention discloses a duplexer. The duplexer is used for conveniently disassembling a PCB cover plate when an inner cavity index of the duplexer and a PCBA coupling index of a circuit board are debugged. A duplexer of an embodiment of the present application includes: a connector, a cavity, a grounding block, a PCB cover plate and a PCBA. A through hole is formed in the grounding block; the connector is fixedly connected with the cavity; at the moment, the inner cavity index of the duplexer and the PCBA coupling index of the circuit board can be debugged firstly; after debugging is finished, the aperture of the through hole of the grounding block is larger than the outer diameter of the end, facing the outside of the cavity, of the connector, so that the end, facing the outside of the cavity, of the connector can penetrate through the through hole of the grounding block, then the grounding block is connected to the cavity, and the assembled duplexer is obtained. In the duplexer of the invention, the installation of the grounding block is carried out after the index debugging is completed, so that the grounding block does not hinder the disassembly of the PCB cover plate, the problem that the connector limits the movement of the grounding block does not exist, and the PCB cover plate can be conveniently disassembled.

Description

technical field [0001] The embodiments of the present application relate to the field of electronic equipment, and in particular to a duplexer. Background technique [0002] The duplexer is the main accessory of the different-frequency duplex radio station and the repeater station. Its function is to isolate the transmitting signal from the receiving signal, so as to ensure that both receiving and transmitting can work normally at the same time. Such as Figure 1A The schematic diagram of the structure of the duplexer shown, wherein the circuit board PCBA (PCBA, printed circuit board assembly) is installed in the duplexer (the circuit board PCBA is not shown in the figure), and the printed circuit board (PCBA) is installed on the circuit board PCBA ( PCB, printed circuit board) cover plate 105, and the PCB cover plate 105 is installed on the cavity 104 of the duplexer. During the assembly process of the duplexer, the connector 102 is first screwed to the ground block 103, a...
