## Background
TECHNICAL FIELD
The present application relates to the field of electric connector, particularly to an electric connector.
BACKGROUND
An electric connector is an electrical device for transferring a current. The electric connectors used specifically in server field must allow for a current of 50 A, which gives rise to hidden risks upon its electric leakage. Electric leakage likely occurs due to improper plug-in between the plug and socket of the electric connector during the usage of the electric connector.
SUMMARY OF THE APPLICATION
To solve the above described technical problem, the present application provides a new electric connector, which is floatable relative to the plug by optimizing its structures, provides a better plug-in and match between itself and the plug, and allows a current of 50 A to run through.
To achieve the above described objective, the present application provides an electric connector comprising:

    
    
        a fastening body, which includes stop grooves;
        a floating body, which includes stop protrusions; and
        a plurality of electric terminals, which respectively include resilient segments,
    
    


wherein the fastening body can overlap the outside of the floating body;
the stop protrusions are respectively located on the two sides of the floating body, and respectively clutched in the stop grooves when the fastening body overlaps the outside of the floating body;
the electric terminals are divided into two sets, and are plugged into the fastening body and the floating body at the same time when the fastening body overlaps the outside of the floating body; and
the resilient segments are located at one end of the electric terminals and are made by folding each electric terminal into a two layer structure.
In a further optimized embodiment, the floating body includes vertical floating stops located at its front and back sides, and transverse floating stops located at its left and right sides, wherein the vertical floating stops abut against the inner surfaces of the front and back sides of the fastening body, and the transverse floating stops abut against the inner surfaces of the left and right sides of the body, when the fastening body overlaps the outside of the floating body.
In a further optimized technical solution, the electric terminals include outer clutching regions and inner clutching regions respectively located at the outer layer structures and inner layer structures of the resilient segments, wherein the outer clutching regions and the inner clutching regions may be respectively clutched in the fastening body and the floating body, when the fastening body overlaps the outside of the floating body; and the resilient segments are respectively provided between the outer clutching regions and the inner clutching regions.
In a further optimized technical solution, there are four vertical floating stops which are respectively located on both ends of the front side and those of the back side of the floating body.
In a further optimized technical solution, the electric terminals include fisheye structures which are located at the ends of the resilient segments and are connected with PCB.
Compared with the prior art, the beneficial effects of the present application are that: the new electric connector is floatable relative to the plug by optimizing its structures and provides a better plug-in and match between itself and the plug.
The optimized structures are characterized in that:

    
    
        there are resilient segments at the ends of the electric terminals made by folding the electric terminal into a two layer structure, and when the plug is improperly plugged into the socket, the resilient segments are deformed (pressed transversely and pulled longitudinally);
        after the floating body is plugged into the fastening body, there is still remaining space within the fastening body for the floating body to move therein, the size of which is determined by the distances between the vertical floating stops and the transverse floating stops. The deformation of the resilient segments can be eliminated through movement of the floating body since the outer and inner clutching regions are respectively clutched in the floating body and the fastening body, accordingly, the tolerance to deflected plug-in posture of the present connector is therefore improved.
