Description

Technical Field

[0001] The embodiments of the present application relate to the field of electronic equipment, and in particular to a duplexer. Background Art

[0002] The duplexer is the main component of the duplex radio and repeater. Its function is to isolate the transmit signal from the receive signal to ensure that both the receive and transmit signals can work normally at the same time. Figure 1A The structural diagram of the duplexer shown in the figure, wherein a printed circuit board assembly (PCBA) is installed in the duplexer (the printed circuit board assembly is not shown in the figure), a printed circuit board (PCB) cover 105 is installed on the circuit board PCBA, and the PCB cover 105 is installed on the cavity 104 of the duplexer. In the assembly process of the duplexer, the connector 102 is firstly threadedly connected with the grounding block 103, and then the screw 101 is used to fix the whole after the connector 102 and the grounding block 103 are connected to the cavity 104, thereby completing the assembly process. Figure 1B FIG. 4 shows a top view of the duplexer product after assembly. Figure 1B As shown, the grounding block 103 is located above the PCB cover 105 .

[0003] After the duplexer is assembled, the inner cavity index of the duplexer and the coupling index of the circuit board PCBA need to be debugged. At this time, the PCB cover 105 needs to be removed, and the grounding block 103 located above the PCB cover 105 will hinder the disassembly process of the PCB cover 105. Therefore, the grounding block 103 also needs to be removed, that is, the screw 101 is removed to separate the grounding block 103 from the duplexer. However, since the grounding block 103 has been threadedly connected to the connector 102 to form a whole, and the connector 102 has installed the cable on the duplexer, and the length of the cable is limited, the movement of the grounding block 103 is restricted. If the grounding block 103 is limited by the length of the cable and can only move a short distance, it is not convenient to disassemble the PCB cover 105. Therefore, it is urgent to optimize the structure of the duplexer. Summary of the invention

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

[0030] See also Figure 2 , an embodiment of the duplexer in the embodiment of the present application includes:

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

[0032] The circuit board PCBA is disposed 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 a cable;

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

[0035] The ground block 202 is connected to the cavity 204 . A through hole 206 is provided on the ground block 202 . The aperture of the through hole 206 of the ground block 202 is larger than the outer diameter of the end of the connector 203 facing the outside of the cavity 204 . The connector 203 passes through the through hole 206 of the ground block 202 .

[0036] In this embodiment, the number of the through holes 206 is not limited.

[0037] The grounding block 202 may be threadedly connected to the cavity 204 by means of screws 201. It should be noted that the connection between the grounding block 202 and the cavity 204 is not limited to threaded connection, but may also be pin connection, key connection or other detachable connection methods. In addition, if the grounding block 202 is not required to be detachable from the cavity 204, a non-detachable connection method may also be used, which is not specifically limited here.

[0038] The grounding block 202 included in the duplexer of this embodiment is provided with a through hole 206. During the assembly process of the duplexer, the connector 203 is fixedly connected to the cavity 204. At this time, the inner cavity index of the duplexer and the coupling index of the circuit board PCBA can be debugged first. After the debugging is completed, since the aperture of the through hole 206 of the grounding block 202 is larger than the outer diameter of the end of the connector 203 facing the outside of the cavity 204, the end of the connector 203 facing the outside of the cavity 204 can be passed through the through hole 206 of the grounding block 202, and then the grounding block 202 is connected to the cavity 204, and the assembled duplexer is obtained. In addition, after the duplexer is assembled, if the inner cavity index and the coupling index of the circuit board PCBA need to be further debugged, since the connector 203 can pass through the through hole 206 of the grounding block 202, the movement of the grounding block 202 is not restricted by the connector 203, and the grounding block 202 can be removed, thereby facilitating the disassembly of the PCB cover 205.

[0039] In the embodiment of the present application, the connection between the connector and the cavity can be an indirect connection. Indirect connection means that the connector is indirectly connected to the cavity through a fixing member, that is, the connector is connected to the fixing member, and the fixing member is fixed on the cavity, which is equivalent to the connector being fixed on the cavity. The indirect connection method will be described in detail below with reference to the accompanying drawings. For details, please refer to Figure 3 , another embodiment of the duplexer in the embodiment of the present application includes:

[0040] Connector 303, cavity 306, ground block 302, PCB cover 307, circuit board PCBA;

[0041] The circuit board PCBA is disposed in the cavity 306;

[0042] The connector 303 is fixedly connected to the cavity 306, and the connector 303 is connected to the parts in the cavity 306 through a cable;

[0043] The PCB cover plate 307 covers the circuit board PCBA;

[0044] The ground block 302 is connected to the cavity 306 . A through hole 309 is provided on the ground block 302 . The aperture of the through hole 309 of the ground block 302 is larger than the outer diameter of the end of the connector 303 facing the outside of the cavity 306 . The connector 303 passes through the through hole 309 of the ground block 302 .

[0045] In this embodiment, the number of the through holes 309 of the ground block 302 is not limited.

[0046] The grounding block 302 may be threadedly connected to the cavity 306 by means of screws 301. It should be noted that the connection between the grounding block 302 and the cavity 306 is not limited to threaded connection, but may also be pin connection, key connection or other detachable connection methods. In addition, if the grounding block 302 is not required to be detachable from the cavity 306, a non-detachable connection method may also be used, which is not specifically limited here.

[0047] In this embodiment, the connector 303 is fixedly connected to the cavity 306 through the fixing member 305. The fixing member 305 has a through hole 308. The connector 303 passes through the through hole 308 of the fixing member 305 and is connected to the fixing member 305. The number of the through holes 308 is not limited.

[0048] The connection between the connector 303 and the fixing member 305 may be a threaded connection. The inner side of the through hole 308 of the fixing member 305 may be provided with a thread, and the connector 303 may be threadedly connected to the fixing member 305 via the thread of the through hole 308 .

[0049] In addition, the connection between the connector 303 and the fixing member 305 may also be a pin connection, a key connection, welding, a riveting or other connection methods, which are not specifically limited here.

[0050] Among them, the fixing member 305 can be a plate-shaped fixing plate, and the through hole 308 is set on the fixing plate. The connector 303 passes through the through hole of the fixing plate and is connected to the fixing plate, and the fixing plate can be fixedly connected to the cavity 306 through the connecting member 304. In this way, it is equivalent to the connector 303 being fixedly connected to the cavity 306.

[0051] It should be noted that the connector 304 may be a screw, and the fixing plate is threadedly connected to the cavity 306. The connector 304 may also be a rivet, and the connection between the fixing plate and the cavity 306 is a rivet connection. The connector 304 may also be a pin or other connector, and the specific type of the connector is not limited.

[0052] In addition, the fixing plate may be connected to the cavity 306 without the connection piece 304 , but the fixing plate may be connected to the cavity 306 by welding, and the connection method between the fixing plate and the cavity 306 is not limited.

[0053] In this embodiment, the fixing member 305 may also be Figure 4 The fixing column shown has a through hole 308 , and the connector 303 passes through the through hole 308 of the fixing column and is connected to the fixing column, and the fixing column can be fixedly connected to the cavity 306 through the connecting piece 304 , which is equivalent to the connector 303 being fixedly connected to the cavity 306 .

[0054] The side wall of the fixing column is provided with an opening 401 , and the cable of the connector 304 can pass through the opening 401 to be connected with the parts in the cavity 306 .

[0055] When the fixing column is cylindrical, a thread may be provided inside the through hole 308 of the fixing column, and the connector 304 may be threadedly connected to the fixing column.

[0056] The fixing column may also be in the shape of a square column, and the connector 303 passes through the through hole 308 of the fixing column and is connected to the fixing column, and the connection method may be welding, bonding or other connection methods.

[0057] The fixed column can be composed of several sub-fixed columns. Figure 4 The fixing column shown is composed of two sub-fixing columns 402. It should be noted that the number of sub-fixing columns is not limited and can be any number.

[0058] In this embodiment, the fixing member and the cavity can be formed in one piece or in separate pieces. When the fixing member and the cavity are formed in separate pieces, the connection between the fixing member and the cavity can be any connection method, including but not limited to threaded connection, welding, rivet connection, pin connection, etc., which are not specifically limited here.

[0059] In the embodiments of the present application, the connection between the connector and the cavity can be an indirect connection or a direct connection. Direct connection means that the connector is in direct contact with the cavity and connected to the cavity. For example, the connector can be directly welded to the cavity, or the connector and the cavity can be threaded or pinned. The specific direct connection method is not limited, and the connection method between the connector and the cavity is also not limited.

[0060] In an embodiment of the present application, if the duplexer has been fully assembled, when it is necessary to debug the inner cavity indicators of the duplexer and the coupling indicators of the circuit board PCBA, the grounding block can be removed. Since the connector can pass through the through hole of the grounding block, the movement of the grounding block will not be restricted by the connector, and the grounding block can be completely removed, thereby facilitating the removal of the PCB cover.

[0061] If the duplexer's inner cavity index and the circuit board PCBA coupling index need to be debugged during the duplexer assembly process, the duplexer assembly method may be to first install the circuit board PCBA on the duplexer, then install the PCB cover on the circuit board PCBA, and fix the connector on the duplexer cavity. After the duplexer's inner cavity index and the circuit board PCBA coupling index are debugged, the ground block is fixedly connected to the cavity.

[0062] Among them, if the duplexer also includes a fixing member and the fixing member is formed separately from the cavity, then, after installing the PCB cover on the circuit board PCBA, the connector needs to be passed through the through hole on the fixing member to connect with the fixing member, and the fixing member connected with the connector needs to be fixed above the cavity.
