[0002] "RF device" generally refers to equipment used for radio frequency (RF) signal processing. RF equipment is widely used in wireless communications, broadcasting and television, radar, radio and other fields. The main functions of RF devices include transmitting, receiving, modulating, demodulating, amplifying and filtering RF signals. There are many specific types of RF devices, for example, RF amplifier: used to amplify RF signals; RF filter: used to select or remove RF signals of specific frequencies; RF switch: used to switch different RF signal paths; RF mixer: used to mix two RF signals of different frequencies to generate a new frequency signal; RF oscillator: used to generate stable RF signals. These devices play an important role in wireless communication systems to ensure stable transmission and reception of signals.

[0030] Among them, the other end of the connecting terminal 21 is provided with a silicone sleeve 23, one end of the silicone sleeve 23 is fixedly connected to the connecting terminal 21, and the other end of the silicone sleeve 23 is rotatably connected to the rotating sleeve 22, and a swivel 26 is rotatably installed on the end of the rotating sleeve 22 close to the silicone sleeve 23, and the silicone sleeve 23 is fixed on the swivel 26 to improve the stability of the rotation of the silicone sleeve 23 on the rotating sleeve 22. At the same time, an annular flange 25 is provided at the end of the connecting terminal 21 away from the wiring harness body 1, and a gap is provided between the flange 25 and the connecting terminal 21 to improve the heat dissipation effect at the connection between the connecting terminal 21 and the RF device body 3.

[0031] It is worth noting that the thickness of the silicone sleeve 23 at one end close to the annular protrusion 25 is greater than the thickness at the other end, and a gap is set between the silicone sleeve 23 and the connecting terminal 21. The setting of this gap allows the silicone sleeve 23 to protrude on the connecting terminal 21 when it is pushed, and when the rotating sleeve 22 pushes the silicone sleeve 23, the silicone sleeve 23 can better contact with the inner wall of the RF device connecting hole, thereby improving the protection effect.

[0033] The working principle of this embodiment: when using this device, after connecting the connecting part 2 to the socket 31 on the RF device body 3, the rotating sleeve 22 is rotated to move the rotating sleeve 22 toward the silicone sleeve 23, and the silicone sleeve 23 is squeezed, so that the silicone sleeve 23 bulges outward to squeeze the inner wall of the socket 31 on the RF device body 3. The silicone sleeve 23 buffers the vibration caused by the operation of the equipment, so that the connecting part 2 and the RF device body 3 are firmly connected, and the factors causing looseness due to the vibration of the RF device body 3 are reduced. At the same time, the silicone sleeve 23 can reduce the entry of dust and water vapor into the connecting terminal 21, thereby increasing its service life.
