A kind of ball contact, it comprises switching contact element, spherical capillary and sleeve pipe; Described switching contact element one end is used for plugging together with the contact of plug, and the described switching contact element other end arranges jack, the hole wall of described jack is arranged the notch run through; Described spherical capillary is made up of leg and the spheroid being arranged at leg one end, and the sphere diameter of described spherical capillary is greater than leg diameter; Spheroid on described spherical capillary inserts in the jack of described switching contact element; When described spherical capillary inserts the described switching contact element other end, described sleeve pipe is enclosed within the other end of described switching contact element again.
In order to realize the utility model better, further technical scheme is:
According to an embodiment of the present utility model, the direction that described jack extends to end end, its aperture reduces gradually.
According to another embodiment of the present utility model, described notch is two.
The utility model can also be:
According to another embodiment of the present utility model, setting table rank, end of described sleeve pipe.
According to another embodiment of the present utility model, described switching contact element adopts copper alloy.
According to another embodiment of the present utility model, described sleeve pipe adopts stainless steel.
Compared with prior art, one of the beneficial effects of the utility model are:
A kind of ball contact of the present utility model, has: 1) stress is discharged by spherical part, and bulb can rotate by any direction, possesses larger deflection angle, thus all can discharge stress; 2) rational in infrastructure, assembling is simple, is convenient to produce in batches.
