[ detailed description ] embodiments

Referring to fig. 1 to 2, the present invention discloses an electrical connector 100 for transmitting large current, which includes a sleeve 10 and a contact spring 2 accommodated in the sleeve 10.

The contact spring 2 includes a first ring 21 and a second ring 22 which are adjacent to each other, a connecting bridge 26 which integrally connects the first ring 21 and the second ring 22 to each other, and a plurality of first resilient pieces 24 and a plurality of second resilient pieces 25. The first and

second rings

21 and 22 have first circular edges 210 located on the same side, respectively, the first elastic pieces 24 extend from the first circular edges 210 of the first ring 21 obliquely and inwardly, and the ends of the first elastic pieces 24 do not extend to the second ring 22. The second elastic pieces 25 extend obliquely inward from the first circular edge 210 of the second circular ring 22, and the first elastic pieces 24 and the second elastic pieces 25 extend in the same direction and are provided with contact points 20. The first elastic sheet 24 and the second elastic sheet 25 are arranged in a pairwise alignment manner in the extending direction, so that the arrangement rule and the number of the contact points are large, and stable transmission of large current is facilitated.

The contact spring 2 comprises two connecting bridges 26 corresponding to each other, the first elastic sheets 24 are divided into two groups by the connecting bridges 26, and the first elastic sheets 24 in each group are all arranged adjacent to each other. The contact spring 2 further comprises a third ring 23, the first, second and

third rings

21, 22, 23 are arranged in sequence, the second and

third rings

22, 23 are integrally connected to each other by two connecting bridges 27, the plurality of second resilient tabs 25 are divided into two groups by the connecting bridges 27, and the second resilient tabs 25 in each group are arranged adjacent to each other. The connecting

bridges

26, 27 are aligned with each other two by two in the arrangement direction of the three circular rings, and the three circular rings are connected as a whole by the connecting

bridges

26, 27.

The first and second

resilient sheets

24 and 25 are provided with inwardly protruding convex hulls, which form the contact points 20, in other embodiments, the contact points 20 are not limited to convex hulls, and can be set as simple points, bending portions, and the like. The free ends of the first and second

elastic sheets

24 and 25 are suspended, and the convex hull is close to the free ends. The inner side of the convex hull protrudes inwards for a distance compared with the tail end of the elastic sheet, the convex hull is provided with a smooth contact cambered surface, the butt joint contact pin 900 is inserted into the contact spring 2 through the friction contact cambered surface, and finally the butt joint contact pin 900 is electrically abutted to the contact cambered surface.

The sleeve 10 includes a forwardly extending receiving cavity 101 for receiving the contact spring 2. The first, second and

third rings

21, 22 and 23 are attached to the inner wall surface 102 of the housing chamber, and the connecting

bridges

26 and 27 are attached to the three rings and attached to the inner wall surface 102 of the housing chamber. The first and second

resilient pieces

24 and 25 extend obliquely inward without adhering to the inner wall surface 102, so that a space capable of elastically rotating exists between the first and second resilient pieces and the inner wall surface 102. The first and

third rings

21, 23 are limited in the accommodating cavity by providing a step on the inner wall surface.

The above-described embodiments are presently preferred, but not necessarily all, embodiments of the invention. Any equivalent changes taken by those skilled in the art from the technical solution of the present invention through reading the specification of the present invention are covered by the claims of the present invention.
