Referring to fig. 1 to 3, the spring leaf of the present invention is used for connecting a male terminal and a female terminal, and includes a first ring 10, a second ring 20, a first rib 30, a second rib 40, and a third rib 50.

The central axis of the second ring 20 coincides with the central axis of the first ring 10. First rib 30 sets up between first ring body 10 and second ring body 20, and first rib 30 has a plurality ofly, and a plurality of first ribs 30 set up around the equidistant of the axis of first ring body 10, and first rib 30 inwards buckles in order to form first inner contact 31. Second rib 40 sets up on first ring body 10, and second rib 40 is provided with a plurality ofly, and a plurality of second ribs 40 set up around the equidistant of the axis of first ring body 10, and second rib 40 is inwards buckled in order to form second inner contact 42. Third rib 50 sets up on second ring body 20, and third rib 50 has a plurality ofly, and a plurality of third ribs 50 set up around the equidistant of the axis of second ring body 20, and third rib 50 inwards buckles in order to form third inner contact 52.

Wherein, the first ring body 10 is provided with a first external contact 11, the end of the second rib 40 is a second external contact 41, the end of the third rib 50 is a third external contact 51, and the second ring body 20 is provided with a fourth external contact 21.

The utility model discloses a theory of operation is: the utility model discloses in, insert the reed and establish in female terminal, so, first external contact 11, second external contact 41 and third external contact 51 promptly with female terminal butt, later, insert the public terminal through first ring body 10 and establish in the reed, so, first internal contact 31, second internal contact 42, third internal contact 52 and fourth internal contact promptly with public terminal butt, so, through the reed, can realize the electric connection between public terminal and the female terminal. The utility model discloses in, first rib 30 makes the reed become an organic whole, easy to assemble, and second rib 40 and third rib 50 make the current circulation route increase. At present, the ordinary reed on the market generally has a contact point with public terminal, has two contact points with female terminal, the utility model discloses a reed has three contact point with public terminal, has four contact points with female terminal, and the increase of contact point makes the current-carrying performance show the reinforcing, and, the utility model discloses change traditional reed on the ground into the little plug of cubic (public terminal contacts with the cubic of second rib 40, first rib 30 and third rib 50 in proper order promptly), the plug is felt, and stability is high, and the structure is more compact.

Moreover, since the second ribs 40 are disposed on the first ring body 10, the third ribs 50 are disposed on the second ring body 20, and a certain distance is provided between the second ribs 40 and the third ribs 50, when the spring is stressed, the second ribs 40 and the third ribs 50 will not generate an excessive counter force, and the insertion and extraction force will not be excessive under the condition of ensuring the contact force.

To better fit the female terminal, the plurality of first inner contacts 31 form a first circular track, the plurality of second inner contacts 42 form a second circular track, and the plurality of third inner contacts 52 form a third circular track, the first, second, and third circular tracks having the same diameter. So, when female terminal's hole was cylindrical, because the diameter of first circular orbit, second circular orbit and third circular orbit is the same, the reed can the disect insertion to female terminal's hole in, the atress is even.

Further, the first, second and third ribs 30, 40, 50 are all bent inward from the middle. The first ribs 30 are spaced apart from the second ribs 40. The third ribs 50 are spaced apart from the first ribs 30. The first ring 10 and the second ring 20 have the same diameter. Therefore, the heat dissipation area is large, the structure is stable, and the electrifying effect is good.

The plurality of second outer contacts 41 form a fourth circular track and the plurality of third outer contacts 51 form a fifth circular track, the fourth circular track having the same diameter as the fifth circular track. The first ring 10 and the fourth circular track have the same diameter. So, when a plurality of outer contacts contacted with female terminal, the atress was even, and stability is good.

The utility model also discloses a connecting terminal, including foretell reed, this connecting terminal still includes public terminal and female terminal. The reed is provided inside the female terminal, and the first outer contact 11, the second outer contact 41, the third outer contact 51, and the fourth outer contact 21 are all in contact with the female terminal. The male terminal is inserted inside the spring, and the first inner contact 31, the second inner contact 42, and the third inner contact 52 all abut against the male terminal. The reed can well realize the electric connection between the female terminal and the male terminal, and has the advantages of more contacts, good current-carrying performance and good stability.
