The present invention can adopt the metal shell 1 and the insulating holder 2 commonly used in the prior art, and therefore, the structure of the metal shell 1 and the insulating holder 2 is not further described in this embodiment. The metal casing 1 may be made of any metal material, such as stainless steel, and the insulating fixing base 2 may be made of any insulating material, such as plastic.
As shown in fig. 5, the fixed terminal 4 includes a first fixed portion 401, a fixed arm 402, a contact portion 403 and a first tail end 404, wherein the fixed arm 402 is connected with the front end of the first fixed portion 401, and the connection portion between the fixed arm 402 and the first fixed portion 401 is bent upwards by 90 ° and the fixed arm 402 is located above the first fixed portion 401 and extends horizontally forwards from the front end of the first fixed portion 401; a contact portion 403 is connected to the front end of the fixed arm 402, the contact portion 403 being for contact with the elastic terminal 3; the first tail end 404 is connected with the rear end of the first fixing portion 401, the connection part of the first tail end 404 and the first fixing portion 401 is bent towards the lower side of the first fixing portion 401 at 90 degrees, the first tail end 404 is located below the first fixing portion 401 and extends downwards from the rear end of the first fixing portion 401, and when the whole fixing terminal 4 is installed in the insulating fixing base 2, the first tail end 404 is located on the outer side of the installation hole 202 and used for being welded with an external circuit board.
As shown in fig. 6, the elastic terminal 3 includes a second fixing portion 301, an elastic arm 302, an elastic abutment portion 303, a second tail end 304, and a guide portion 305.

In the embodiment of the invention, the elastic arm 302 and the fixed arm 402 are arranged in a staggered manner along the width direction, and the width of the fixed arm 402 is smaller than that of the elastic arm 302, so that the overlapping area between the elastic arm 302 and the fixed arm 402 is reduced, and the high-frequency transmission performance of the connector is further improved. The distance between the elastic arm 302 and the fixed arm 402 gradually decreases toward the front end.

In the embodiment of the present invention, the second fixing portion 301 and the first fixing portion 401 may be further designed to have a dislocation structure based on being perpendicular to each other, where the first fixing portion 401 is lower than the bottom edge of the second fixing portion 301, and the second fixing portion 301 and the first fixing portion 401 do not overlap on the opposite surfaces as shown in fig. 8.

In the embodiment of the present invention, the first fixing portion 401 is provided with a through hole 405, and the through hole 405 can play a role in adjusting characteristic impedance.
In order to ensure the stability of the terminal installation position, a plurality of limit grooves can be arranged inside the insulating fixing base 2 for assisting the installation and fixation of the elastic terminal 3 and the fixed terminal 4.
The installation process and the working principle of the connector are as follows:
firstly, an elastic terminal 3 and a fixed terminal 4 are arranged in an insulating fixed seat 2, and then a metal shell 1 is sleeved outside the insulating fixed seat 2. In the natural state, i.e. the closed state, the elastic abutting portion 303 on the elastic terminal 3 is electrically connected with the contact portion 403 on the fixed terminal 4, and the soldering leg of the second tail end 304 on the elastic terminal 3 and the soldering leg of the first tail end 404 on the fixed terminal 4 are respectively soldered with an external circuit board, so as to realize a complete signal transmission loop. When the signal transmission loop needs to be switched, the plug pin of the external plug is inserted into the insulation fixing seat 2 through the plug hole 201 at the front end of the insulation fixing seat 2, and after the plug pin enters the cavity inside the insulation fixing seat 2, the plug pin is contacted with the guide part 305 at the forefront end of the elastic terminal 3, the plug pin applies a force towards the plug pin insertion direction to the guide part 305, and simultaneously applies a force perpendicular to the plug pin insertion direction to the guide part 305, and the guide part 305 moves away from the fixed terminal 4 under the action of two forces applied by the plug pin; when the plug pin is continuously inserted between the elastic terminal 3 and the fixed terminal 4 along the side surface of the guide portion 305, the guide portion 305 can drive the elastic arm 302 to elastically displace in a direction away from the fixed arm 402, so as to drive the elastic abutting portion 303 to disconnect from the contact portion 403, and the connector is changed from the closed state to the open state; when the plug pin is pulled out from the inside of the insulation fixing base 2, the elastic abutting portion 303 is contacted with the contact portion 403 under the action of the elastic force of the elastic arm 302, so that the connector of the invention is returned to the closed state.
Example 2
Embodiment 2 describes a high-frequency coaxial switch connector, unlike embodiment 1, the elastic arm 302 and the fixed arm 402 are still arranged offset in the width direction, but the elastic abutting portion 303 is arranged on the upper side (not shown) of the front end of the elastic arm 302, and when the elastic arm 302 is in a natural state, the elastic abutting portion 303 contacts the lower side (not shown) of the contact portion 403. The first fixing portion 401 and the second fixing portion 301 are also disposed in a staggered manner in a perpendicular manner, but the first fixing portion 401 is higher than a top edge (not shown) of the second fixing portion 301.
The elastic arm 302 and the fixed arm 402 are only overlapped in a small part, the first fixed part 401 and the second fixed part 301 are not overlapped at all, interference between the two terminals in the communication process can be effectively reduced by reducing the overlap ratio between the elastic terminal 3 and the fixed terminal 4, inductance and capacitance of the connector in a passage state are reduced, and the overall electrical performance is improved. The connector can meet the SI parameter specification requirement of DC-10GHz in high-frequency transmission performance.
Based on the structural design of example 1 or example 2, a simulation experiment is performed on the electrical performance of the connector of the present invention, and the 5G high frequency transmission specification standard that needs to be satisfied by the experiment is shown in fig. 15.

The simulation experiment results obtained by comparing the simulation actual measurement curves with the standard specification curves in fig. 10-14 are shown in fig. 16, and it is known that the high-frequency coaxial switch connector can meet the parameter specification requirements on standing-wave ratio, insertion loss and isolation in each frequency band of DC 0-10GHz under the normally closed state or normally open state.
The foregoing is merely a preferred embodiment of the present invention, and it should be noted that modifications and variations could be made by those skilled in the art without departing from the technical principles of the present invention, and such modifications and variations should also be regarded as being within the scope of the invention.
