Fig. 2 is current connector assembling schematic diagram in the present invention；
Fig. 3 is the generalized section of current connector in the present invention.
Specific embodiment
With reference to the accompanying drawings and examples the present invention will be described in detail.
High-voltage great-current connector construction provided in the present embodiment is as illustrated in the accompanying drawings from 1 to 3.
High-voltage great-current connector in the embodiment includes the socket that plug is adapted to plug, and the plug side is provided with
Plug male terminal 3, socket side is provided with socket female terminal 2, is matched by male terminal and female terminal due to plug and socket
Structure is attached, therefore omits the external structure of plug and socket in the accompanying drawings.In the socket female terminal 2 of socket side be provided with
The jack that male terminal is plugged, male terminal is provided with hat spring 1 with female terminal connection.
The structure of hat spring 1 is as shown in Figure 1.Hat spring 1 includes the fixed part 104 and 105 at two ends, also including middle connection
Portion, the connecting portion by continuous concavo-convex shell fragment, such as 101, and the elastic piece structure for disconnecting up and down, as above shell fragment 102 and lower bullet
The uniform alternate composition of elastic piece structure that piece 103 is constituted, i.e., continuous concavo-convex shell fragment both sides are the elastic piece structure for disconnecting up and down, are broken up and down
The elastic piece structure both sides opened are continuous concavo-convex elastic piece structure.The shell fragment knot that either continuous concavo-convex elastic piece structure still disconnects up and down
Structure, its shell fragment two ends are connected respectively with fixed part 104,105.It is provided with deformation connection space, upper shell fragment 102 between shell fragment up and down
Do not stress with lower shell fragment 103 and be not attached under state, during by outside axial force, upper shell fragment contacts with lower shell fragment.
In hat spring structure in the prior art, the hat being all made up of continuous concavo-convex elastic piece structure is often used
Spring, so results in contact engaging and separating force greatly, is easily caused terminal during plug and is carried over, using such as the hat of structure in the present embodiment
After spring, the elastic piece structure due to including disconnection, the contact engaging and separating force between terminal is then greatly reduced, and due in use
Receive upper and lower shell fragment after axial force still to contact, the biography of electric current can't be affected using hat spring structure as shown in this embodiment
Lead.On the one hand in actual use, in order that the material of manufacture hat spring maximizes the use, on the other hand make concavo-convex
The elastic energy of deformation of shell fragment is vertical to be consistent with the deformation connection space of upper and lower shell fragment, preferably preferably by concavo-convex shell fragment length and upper shell fragment and
Lower shell fragment length sum is set to equal.
Further to realize that upper and lower shell fragment can unclamp or combination according to stress, the upper shell fragment is all outside with lower shell fragment
Or it is inwardly protruding, it is not parallel with hat spring axis.Still further preferably, as it is shown in the figures, upper shell fragment 102 and lower shell fragment
103 outwardly convexs, and be in 12-25 degree angle with hat spring axis.Up and down shell fragment be set to the angle that axis is formed it is identical, once
Hat spring structure is subject to the power in axis direction, then the fixed part and upper and lower shell fragment for being preced with spring is deformed upon, and upper and lower shell fragment is then in
Portion moves, and links together, it is ensured that the contact between shell fragment, that is, ensure that the conduction of electric current.
It is the phase drawing that further takes effect for ease of the copper alloy cast member that manufacture, the hat spring in embodiment are formed in one
Power, by hat spring discontinuous structure is provided with, and will be preced with spring and is designed as a tubulose do not closed.To ensure the elasticity of hat spring structure, hat
Concavo-convex shell fragment in spring connecting portion includes recess and convex portion, and the recess and convex portion quantity are 2-4 optimal.
Further, it is to coordinate the purpose used safely, plug male terminal top is additionally provided with insulator cap 4.
It is last it should be noted that above example is only to illustrate the technical scheme of the embodiment of the present invention rather than it is entered
Row is limited, although being described in detail to the embodiment of the present invention with reference to preferred embodiment, one of ordinary skill in the art
It should be understood that still the technical scheme of the embodiment of the present invention can be modified or equivalent, and these are changed or wait
Amended technical scheme can not be also set to depart from the scope of embodiment of the present invention technical scheme with replacement.
