Embodiment
The present invention is described in further detail with reference to embodiment, but the implementation of the present invention is not limited to this.
As shown in figure 1, Fig. 1 is the switching contact element structural representation according to one embodiment of the invention, its contact of transferring
The one end of part 7 is used to plug together with the contact of plug, and the other end of switching contact element 7 sets jack 71, and preferably jack 71 is to end
Its aperture of direction of end extension is gradually reduced, i.e., axially split groove in jack 71 and close up.When spherical capillary 8 as shown in Figure 2
Spherical (spheroid 82) insertion jack 71 after there is positive pressure, it is ensured that switching contact element 7 and spherical capillary 8 are abutted against
Touch.Preferably, the notch 72 run through can be set on the hole wall of the jack 71, further, this Fig. 1 shows that notch 72 is two
The situation of bar.
Switching contact element 7 is preferred to use high property copper alloy manufacture.
As shown in Fig. 2 Fig. 2 is the structural representation according to the spherical capillary of one embodiment of the invention, spherical capillary 8 by
Leg 81 is constituted with the spheroid 82 for being arranged at the one end of leg 81, and the diameter of spheroid 82 of preferably a kind of spherical capillary 8 is more than leg 81
The structure of diameter.
The diameter of spheroid 82 is more than leg 81, less than the diameter of the jack 71 of switching contact element 7.
As shown in figure 3, Fig. 3 is the sleeve structure schematic diagram according to one embodiment of the invention, inserted in the spherical capillary 8
In the case of entering the other end of switching contact element 7, described sleeve pipe 9 is enclosed on the other end of the switching contact element 7 again.It is described
