Selectable, the interior contact plate of described shell fragment is the closer to connecting plate, and size is less, is narrow, the middle wide shape in two ends.
Selectable, described interior contact plate, described external touch panel lay respectively at the both sides of described rebound.
Selectable, described connecting plate one end is connected with described rebound, and the other end has a plurality of fixed claws, and described fixed claw is flare shape.
Selectable, described fixed claw is isosceles trapezoid.
Selectable, shell fragment is uniformly distributed on described spring, and described fixed claw is corresponding with described shell fragment.
Selectable, described spring is that punching press is one-body molded.
, it comprises above-mentioned sheet spring, and socket, plug, and described socket has jack, and described spring is fixed in described jack, and described interior contact plate coordinates with described plug, and described external touch panel coordinates with described jack.
Selectable, the diameter of first periphery at described interior contact plate place equals the diameter of described plug.
Selectable, the diameter of second periphery at described external touch panel place equals the diameter of described jack.
Beneficial effect of the present invention:
The interior contact plate of this sheet spring structure and external touch panel are all positioned at the free end of shell fragment, and size selectable range is wider, and in increasing, the size of contact plate, external touch panel, has just increased conductive contact area; By interior contact plate, contact with plug, external touch panel contacts with jack, and contact plate and external touch panel in rebound directly connects form directly contact conduction, and to sum up, sheet spring structure has good overcurrent capability.

Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.
As shown in Fig. 3～5, sheet spring 1 comprises two connecting plates 11 and a plurality of shell fragment 12, shell fragment 12 comprises interior contact plate 121, rebound 122, the external touch panel 123 connecting successively, the two ends of rebound 122 are fixedly connected with two connecting plates 11 respectively, between adjacent two shell fragments 12, have spacing (being that adjacent two shell fragments do not contact), second periphery 127 at first periphery 126 at interior contact plate 121 places of each shell fragment 12, external touch panel 123 places of each shell fragment 12 coaxially arranges.Sheet spring 1 can be by the one-body molded processing and fabricating of punching press, and interior contact plate 121, rebound 122, external touch panel 123 directly connect, and have increased electric current cross-sectional area, reduce contact resistance.
In Fig. 4, the first periphery 126, the second periphery 127 use thick dashed line represent.A plurality of interior contact plates 121 are all positioned on a first invisible periphery 126, and a plurality of external touch panels 123 are all positioned on a second invisible periphery 127, and the diameter of the first periphery 126 is less than the diameter of the second periphery 127.The first periphery 126, the coaxial setting of the second periphery 127 refer to that the central shaft of the first periphery is identical with the central shaft of the second periphery.
Sheet spring 1 can directly be fixed on socket by connecting plate 11, also can on connecting plate 11, increase fastening structure, and preferred, connecting plate 11 one end are connected with rebound 122, and the other end has a plurality of fixed claws 111, and fixed claw 111 is flare shape.That the fixed claw 111 that is flare shape has is fixed, increase sheet spring and the contact area of socket, the effect of additional conductive.Fixed claw 111 can be the shapes such as square, triangle, isosceles trapezoid.Preferably, fixed claw 111 is isosceles trapezoid, adopts fixed claw 111 fixations of isosceles trapezoid.The number of fixed claw 111 and distribution can arrange arbitrarily, and preferred, shell fragment 12 is uniformly distributed on sheet spring 1, and fixed claw 111 is corresponding with shell fragment 12, and this structure makes the integral body of shell fragment 12 stressed evenly, makes sheet spring 1 have the effect of self-regulation clamping force.
As shown in Figure 6, electric connector comprises sheet spring 1, and socket 2, plug 3, and socket 2 has jack 21, and sheet spring 1 is fixed in jack 21, and interior contact plate 121 coordinates with plug 3, and external touch panel 123 coordinates with jack 21.
The diameter of the first periphery 126 is less than or equal to the diameter of plug 3, and the diameter of the second periphery 127 is greater than or equal to the diameter of jack 21.Preferably, the diameter of first periphery 126 at interior contact plate 121 places equals the diameter of plug 3.Preferably, the diameter of second periphery 127 at external touch panel 126 places equals the diameter of jack 21.Adopt said structure to be convenient to plug.
Although the present invention is described in conjunction with above embodiment, but the present invention is not limited to above-described embodiment, and being only subject to the restriction of claims, those of ordinary skills can easily modify to it and change, but do not leave essence design of the present invention and scope.
