For another example, the first connecting portion 210 may have an engaging groove structure, the inner surface of the mounting hole may have a protrusion structure, and the first connecting portion 210 may be inserted into the first connecting hole 2101 to engage the engaging groove structure of the first connecting portion 210 with the protrusion structure of the inner surface of the mounting hole.

Optionally, in some other embodiments, the second connecting portion 310 has a mounting hole, and the first connecting portion 210 is inserted into the mounting hole and is matched with the mounting hole in an inserting manner. The plug-in fit may also be considered a male-female fit. For example, the first connection part 210 may be interference-fitted with the fitting hole, but is not limited thereto.

In one embodiment, referring to fig. 1, 5 and 6, the cavity assembly 100 includes a connector 50, the connector 50 is disposed on the cavity 10, and an inner core (i.e., an inner conductor of the connector 50 for transmitting signals) of the connector 50 is connected to the first signal transmission element 20. At this time, the first signal transmission member 20 may be a connection rod (fig. 5 and 6 exemplarily show this case), a connection piece, a connection post, a tap, etc., but is not limited thereto. The second signal transmission member 30 may be a tap (fig. 5 and 6, which is exemplarily shown), a connection bar, a connection piece, a connection column, etc., but is not limited thereto.

With such an arrangement, since the connector 50 is disposed on the cavity 10 and the inner core of the connector 50 is connected to the first signal transmission member 20, the new term first signal transmission member 20 can transmit signals between the connector 50 and the second signal transmission member 30, so as to facilitate the transmission of signals of external devices to the second signal transmission member 30 or the transmission of signals of the second signal transmission member 30 to external devices.

It is understood that the connector 50 may be various types of connectors for being disposed on the filter, for example, BMA connector (blind mate connector), SMA connector, SMP connector, MBX connector, PSMP connector, TX connector, etc., but is not limited thereto.

It should be noted that in other embodiments, the inner core of the connector 50 may not be connected to the first signal transmission member 20, but connected to the second signal transmission member 30. At this time, the second signal transmission member 30 can transmit signals between the connector 50 and the first signal transmission member 20.

It should also be noted that in other embodiments, the first signal transmission element 20 may be a connector, and the inner core of the connector has the first connection portion 210. At this time, the first connection portion 210 may be a portion of the inner core of the connector.

It should also be noted that in other embodiments, the second signal transmission element 30 may be a connector, and the inner core of the connector has the second connection portion 310. At this time, the second connection portion 310 may be a portion of the inner core of the connector.

In one embodiment, referring to fig. 1 to 6, the cavity assembly 100 includes a connector 50, the connector 50 is disposed on the cavity 10, and an inner core of the connector 50 is connected to the first signal transmission member 20; alternatively, the first signal transmission member 20 is a connector, and the inner core of the connector has the first connection portion 210. The second signal transmission member 30 includes a first transmission section 31 and a second transmission section 32, and the first transmission section 31 is connected with the second transmission section 32 in a bent manner. An included angle is formed between the first transmission section 31 and the second transmission section 32, for example, a right angle may be formed between the first transmission section 31 and the second transmission section 32, that is, the first transmission section 31 and the second transmission section 32 may be perpendicular; of course, an acute angle may be formed between the first transmission section 31 and the second transmission section 32. The first transmission section 31 has a second connection portion 310.

With such an arrangement, since the second signal transmission member 30 includes the first transmission section 31 and the second transmission section 32 connected in a bending manner, and the first transmission section 31 has the second connection portion 310, the positions of the first transmission section 31 and the first signal transmission member 20 are adapted conveniently, so as to facilitate the detachable connection between the second connection portion 310 and the first connection portion 210; moreover, the second signal transmission part 30 can be wound or turned around while being connected and matched with the first signal transmission part 20, which is beneficial to adapting to the environment inside the cavity 10.

It is understood that the second signal transmission member 30 may include one or more other transmission segments besides the first transmission segment 31 and the second transmission segment 32, for example, a third transmission segment, and the third transmission segment and the second transmission segment 32 may be connected in a bent manner, for example, as shown in fig. 5 and 6; but is not limited thereto, and may further include, for example, a fourth transmission segment or the like.
