Patent ID: 8523618

Claim:
A high frequency adapter, electrically connecting a docking device to a circuit board, comprising: an insulating body, located above the circuit board, wherein the insulating body has a first end surface facing the docking device; a radio frequency (RF) signal terminal, fixed in the insulating body, wherein the RF signal terminal has a first conductive connection portion conductively connected to the circuit board, and a first contact portion extending from the first conductive connection portion is exposed out of the first end surface; two grounding terminals, fixed in the insulating body and located at two sides of the RF signal terminal, wherein each of the grounding terminals has a second conductive connection portion conductively connected to the circuit board, and a second contact portion extending from the second conductive connection portion is exposed out of the first end surface, wherein lateral projections of the RF signal terminal and the two grounding terminals are approximately the same and overlapping, and the first contact portion and two second contact portions are commonly pressed by the docking device; wherein an upper surface of the circuit board is disposed with a coaxial cable connector plugged by a cable docking head, and the high frequency adapter is conductively connected to the coaxial cable connector; and wherein the coaxial cable connector comprises a main body, a movable terminal and a fixed terminal fixed in the main body, and a shielding shell covering the main body, wherein before the cable docking head is plugged into the coaxial cable connector, the movable terminal and the fixed terminal are conductively connected, and when the cable docking head is plugged into the coaxial cable connector and is conductively connected to the movable terminal, the movable terminal and the fixed terminal are disconnected.
