[0044] Unless otherwise defined, all technical terms used in the embodiments of the present invention have the same meanings as commonly understood by those skilled in the art.

[0045] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0046] On the one hand, combined with Figure 1 and Figure 2 As shown, this embodiment provides a connector, which includes: an insulating body 1, a first terminal 2 and a second terminal 3.

[0047] The first terminal 2 and the second terminal 3 are both located in the insulating body 1; the insulating body 1 is provided with a plug-in hole 11; the first terminal 2 includes a deformation portion 21, and the deformation portion 21 spans the plug-in hole 11; the second terminal 3 includes at least one contact portion 31, and at least one contact portion 31 is located on the opening side of the deformation portion 21 facing the plug-in hole 11.

[0048] The connector includes a disconnected state and a connected state: in the disconnected state, the deformation portion 21 elastically deforms toward the direction away from the opening side of the plug hole 11, and at least one contact portion 31 is disengaged from the deformation portion 21; in the connected state, the deformation portion 21 elastically deforms toward the direction close to the opening side of the plug hole 11, and at least one contact portion 31 is electrically contacted with the deformation portion 21.

[0049] The connector of this embodiment includes an insulating body 1, and a first terminal 2 and a second terminal 3 located inside the insulating body 1. The first terminal 2 and the second terminal 3 are electrically connected through at least one contact portion 31. When the first terminal 2 is subjected to an external force along the direction of the plug-in hole 11, the deformation portion 21 thereon is deformed, thereby realizing the switching of the disconnected state and the conductive state of the connector. In particular, in the conductive state, the first terminal 2 maintains a pressed contact with the contact portion 31 of the second terminal 3 under the elastic action of the deformation portion 21, has better contact stability, and the connector has a simple structure and high reliability.

[0050] The plug hole 11 is used to plug in the RF probe. In the initial state, the connector is in the on state. When the RF probe is inserted, the RF probe abuts the deformation part 21 and presses the deformation part 21 downward to deform it, and the deformation part 21 separates from the contact part 31, so that the connector switches from the on state to the off state. After the RF probe is pulled out, the deformation part 21 returns upward under the action of its own elasticity and abuts against the contact part 31 again, so that the connector switches from the off state back to the on state.

[0051] In some possible implementations, the connector of this embodiment is a radio frequency switch connector, which is mainly used in switching application scenarios of radio frequency signals. The radio frequency switch connector can realize fast switching between antennas and is used in antenna array systems, mobile communication base stations and other occasions where antenna switching is required. In communication systems, the radio frequency switch connector can realize fast switching between different communication channels to achieve multi-channel communication. In occasions where signal routing is required in radio frequency measurement systems, communication equipment, etc., the radio frequency switch connector realizes fast switching between different signal paths. For example, when the communication standard or working mode needs to be switched, the radio frequency switch connector realizes fast switching between different standards or modes. In high-power equipment, the radio frequency switch connector can realize switching between different power levels, such as switching when the transmit power needs to be adjusted. In systems that require redundant backup of signals, the radio frequency switch connector realizes fast switching between primary and standby signals or devices.

[0052] The connector of this embodiment has low loss and high frequency characteristics, and can realize fast and seamless switching of radio frequency signals between different paths or devices, and can be widely used in communication, measurement and other fields that require radio frequency signal switching.

[0053] In some possible implementations, the insulating body 1 is made of insulating material. The insulating material includes but is not limited to polyamide (also known as nylon, Nylon), polycarbonate (Polycarbonate, PC), fiberglass (Fiber Glass, FG), polyethylene (Polyethylene, PE), polyether (Polyether), polyethylene Glycol Terephthalate (Polyethylene Glycol Terephthalate, PET), polymethyl methacrylate (Polymethyl Methacrylate, PMMA), polypropylene (Polypropylene), polystyrene (Polystyrene, PS), polyvinyl chloride (Polyvinyl Chloride, PVC), etc. Any one of the above materials or any combination of several materials can be used to form this embodiment.

[0054] Combination Figure 2 and Figure 3 As shown, in some embodiments, the deformation portion 21 includes at least one avoidance portion, and at least one contact portion 31 is located in the at least one avoidance portion; in the conductive state, at least one contact portion 31 has at least two contact points with the edge of at least one avoidance portion.

[0055] Through the above arrangement, at least one contact portion 31 of the second terminal 3 can be connected to the first terminal 2 through at least two contact points, and a more stable and reliable electrical contact connection is established between the first terminal 2 and the second terminal 3 .

Compared with a single-point contact, the two contact points have more stable and reliable electrical contact connection performance.

[0058] When the number of avoidance parts is two, such as Figure 3As shown, each avoidance portion can construct two contact points, and the two avoidance portions are in contact with the two contact portions 31 respectively, so as to form four contact points a, b, c and d.

The two avoidance parts surrounded by the four support parts 211 are 180° apart, that is, the two avoidance parts are symmetrically arranged on the first terminal 2, which makes the first terminal 2 and the second terminal 3 have four contact points, and the electrical contact performance is more reliable.

[0064] Combination Figure 4 As shown, in some embodiments, the first terminal 2 further includes a first connecting portion 22, and the first connecting portion 22 is connected to one of the supporting portions 211.

[0065] Combination Figure 3 and Figure 4 As shown, in some embodiments, a first pin 221 is provided at one end of the first connection portion 22 extending in a direction away from the opening side of the plug hole 11.

[0066] Combination Figure 3 and Figure 5 As shown, in some embodiments, one end of the contact portion 31 is connected to the insulating body 1 , and the other end of the contact portion 31 extends toward the deformation portion 21 .

[0067] Through the above arrangement, the contact portion 31 is protruded on the insulating body 1 along the probe insertion direction, which can ensure that the connection between the deformation portion 21 and the contact portion 31 will not be interfered by the insulating body 1, thereby improving the reliability of electrical contact.

[0068] Combination Figure 5 As shown, in some embodiments, the number of the contact portions 31 is two, and the two contact portions 31 are located on opposite sides of the plug hole 11; the second terminal 3 also includes a third connecting portion, which is buried in the insulating body 1 and respectively connects the two contact portions 31.

[0069] The two contact portions 31 are symmetrically arranged on both sides of the plug hole 11, so that the first terminal 2 and the second terminal 3 have four contact points, and the electrical contact performance is more reliable. The third connecting portion is buried in the insulating body 1 to electrically connect the two contact portions 31.

[0075] Through the above arrangement, the deformation portion 21 elastically deforms along the axial direction of the plug interface under the cooperation of the first positioning structure 212 and the second positioning structure 12, ensuring that the first terminal 2 will not move laterally and the deformation portion 21 remains at a position corresponding to the contact portion 31.

[0076] In some possible implementations, one of the first positioning structure 212 and the second positioning structure 12 is a protruding structure, and the other of the first positioning structure 212 and the second positioning structure 12 is a notch structure.

[0078] Combination Figure 5 As shown, in some embodiments, at least one first positioning structure 212 is located in the middle of the deformation portion 21.
