Specific embodiment
The present invention is further elaborated and is illustrated with Figure of description combined with specific embodiments below:
Embodiment one:
Please refer to Fig. 1-Fig. 3, a kind of Multi-contact contact includes main body 110.
Main body 110 is equipped with concave surface 111, and concave surface 111 offers a plurality of first gap 1111 and a plurality of second gap 1112, the
One gap 1111 and the second gap 1112 are parallel to each other and staggered, connection strap 1113 are equipped in the middle part of the first gap 1111, even
1113 both ends of narrow bars are respectively equipped with to the curved elastic slice 1114 that warps in concave surface 111.The elastic slice that warps at same 1111 both ends of connection strap
1114 end is folded to two ends in the first gap 1111 respectively.
The contact is put into the external member of cooperation, and when external plug-in insertion, plug-in unit contacts main body 110 and 111 phase of concave surface
Pair convex surface, therefore contacted with the connection strap 1113 for being set to the middle part of the first gap 1111, electric current passes through multiple tilting elastic slices 1114
The conducting of external member inner wall is contacted, the elastic slices 1113 that warp multiple at this time increase effective conductive cross-sectional area A in the form of multifinger；Have simultaneously
The length of the conductive distance L actually short and small elastic slice 1114 that warps is imitated, i.e. effectively conduction distance L becomes smaller；Make using identical material
