Preferably, the end seat is flexible and end face of from the end seat caves inward wearing of forming that opening extends out
Groove, the end face of the end seat, which is abutted, circular cone, and the end face of the circular cone is supported with the spring being placed in the cavity of said inner tube
Connect.
By using such scheme, in use, needle shaft is moved into the cavity of inner tube so that circular cone is transported into wears groove
It is dynamic, expand outwardly end seat so as to extrude end seat, and contacted with the inwall of inner tube, constitute current conduction path, and end seat with
The larger face contact of contact surface is formed between inner tube, thus makes probe adapter that there is preferable electric connection.
Preferably, the wears groove is opened in the center of the end seat.
By using such scheme so that end seat is extended out uniformly when being extruded by circular cone, integrally.
Preferably, the end seat is beryllium copper end seat.
By using such scheme, beryllium copper has higher elasticity and electric conductivity.
In summary, the utility model has the advantages that:
First, being sheathed on the insulation sleeve outside needle shaft so that probe adapter when in use, the inwall of insulation sleeve and inner tube
Contact will not form current conduction path, so that the conduction that electric current is formed from the contact by end seat with inner tube as much as possible
Path, has the advantages that to reduce current conduction path, probe adapter is met answering for the apparatus fields such as RF high frequencies, 5G
With;
Second, needle shaft body fits in insulation sleeve, fallen into other debris are effectively prevented by needle shaft body and insulation sleeve
Effect in the space of formation;
Third, passing through the mutual cooperation of circular cone and end seat that is flexible and offering wears groove so that probe adapter
When in use, end seat is expanded outwardly, and is contacted with the inwall of inner tube, so that current conduction path is constituted, and end seat and inner tube
Between form the larger face contact of contact surface, it is ensured that probe adapter has preferable electric connection.
