[0039] A detection coil 41 is disposed in the housing.

[0040] The invention transmits radio frequency energy from one side of the connecting device to the other side by designing a head and a seat that are adapted to each other. After the connecting device is connected, the linkage part and the detection part 4 work in linkage to automatically detect whether the connecting device is in a reliable connection position. The detection of the reliable connection position is used as a basis for judging whether the radio frequency system can transmit radio frequency signals through the connecting device.

[0043] The head outer conductor 11 and the seat outer conductor 22 are adapted to each other, and the head inner conductor 12 and the seat inner conductor 21 are adapted to each other.

[0044] The frame 31 is connected to the seat outer conductor 22 .

[0045] The contact ring 32 is sleeved on the seat outer conductor 22 .

[0046] The contact rod 34 is provided with a compression spring 33 , and the compression spring 33 is located between the contact ring 32 and the frame 31 .

[0047] The housing is connected to the seat outer conductor 22 .

[0049] A return spring 45 is provided between the rocker rod 43 and the housing.

[0050] Embodiment 1:

[0051] The self-detecting RF connection device has two states, as shown in the following Figure 2 The device is shown in the disengaged state, and the inner and outer conductors of the head have not moved to a position for reliable connection. At this time, the contact ring 32 in the device drives the contact rod 34 to a relaxed position under the action of the compression spring 33, and the contact rod 34 is disengaged from the detection unit 4. The detection unit 4 gives a signal indicating that the device is in the disengaged state, and the device cannot transmit radio frequency signals.

[0052] Another state of the self-detecting RF connection device is the connection state, as shown in the attached Figure 3 The figure shows a schematic diagram of the device connection state. The inner and outer conductors of the head move to a position of reliable connection. At this time, the outer conductor 11 of the head in the device pushes the contact ring 32 to move to the left. At the same time, the contact ring 32 drives the contact rod 34 to move to the left and contact the detection part 4. At the same time, the compression spring 33 is compressed by the force of the contact ring 32. At this time, the detection part 4 gives a signal indicating that the device is in a connected state and can transmit radio frequency signals.

[0053] When the detection unit 4 is in the detection state, as shown in the attached Figure 4 , 5 As shown, when the contact rod 34 is inserted, the current of the detection coil 41 changes, which can be used as a logical quantity to detect whether the contact rod 34 is inserted.

[0054] As the self-detected RF connection device reaches a reliable connection position, the contact rod 34 pushes the swing rod 43, and the swing rod 43 rotates around the rotating shaft 42 to overcome the restoring force of the restoring spring 45, and finally contacts the static contact 44. After the swing rod 43 and the static contact 44 contact, a circuit loop is formed through the contact connection line 46 and the signal processing circuit board 47, and the detection logic formed by the integrated detection coil 41 and the static contact 44 is converted into a signal indicating that the RF connection device is in a reliable connection position through the signal processing circuit board 47.

[0055] As attached Figure 6 As shown, the detection coil 41 is connected to X1, and the rocker rod 43 and the static contact 44 are connected to X2.

[0057] Step 1, the head outer conductor 11 and the seat outer conductor 22 are connected to each other, and the head inner conductor 12 and the seat inner conductor 21 are connected to each other;

[0058] Step 2: During the docking process, the head outer conductor 11 pushes the contact ring 32 to move, and drives the contact rod 34 to move;

[0059] Step 3, the contact rod 34 enters the detection coil 41 and pushes the swing rod 43 to move, and the swing rod 43 overcomes the restoring force of the reset spring 45 around the rotating shaft 42 and finally contacts the static contact 44;

[0060] When the contact rod 34 causes the current of the detection coil 41 to change, and the rocker arm 43 and the static contact 44 come into contact and form a circuit loop with the signal processing circuit board 47 through the contact connection line 46, it is determined that the head and the seat are in a connected state, and the signal processing circuit board 47 converts it into a signal indicating that the radio frequency connection device is in a reliable connection position.

[0061] Working principle description: the head outer conductor 11 and the seat outer conductor 22 are butted against each other, and the head inner conductor 12 and the seat inner conductor 21 are butted against each other;

[0062] During the docking process, the head outer conductor 11 pushes the contact ring 32 to move, and drives the contact rod 34 to move;

[0063] The contact rod 34 enters the detection coil 41 and pushes the swing rod 43 to move. The swing rod 43 overcomes the restoring force of the return spring 45 around the rotating shaft 42 and finally contacts the static contact 44.

[0064] When the contact rod 34 causes the current of the detection coil 41 to change, and the rocker arm 43 and the static contact 44 come into contact and form a circuit loop with the signal processing circuit board 47 through the contact connection line 46, it is determined that the head and the seat are in a connected state, and the signal processing circuit board 47 converts it into a signal indicating that the radio frequency connection device is in a reliable connection position.
