A high current connection structure includes a spring terminal 1, the spring terminal 1 includes a fixing plate 11, a first clamping portion 12 and a second clamping portion 13;

[0045] The first clamping portion 12 is fixed on a long side of the fixing plate 11 and is used to clamp the first male terminal 2;

[0046] The second clamping portion 13 is fixed on the other long side of the fixing plate 11 and is used to clamp the second male terminal 3;

[0047] The first clamping portion 12 and the second clamping portion 13 each include a plurality of elastic pieces 1213 spaced apart along the length direction of the fixing plate 11;

[0048] All the elastic sheets 1213 of the first clamping portion 12 are divided into two groups: the elastic sheets 1213 of one group are aligned along the length direction of the fixing plate 11, and the elastic sheets 1213 of the other group are aligned along the length direction of the fixing plate 11, and a first clamping space 121 for clamping the first male terminal 2 is formed between one side of the elastic sheets 1213 of one group in the thickness direction of the fixing plate 11 and one side of the elastic sheets 1213 of the other group in the thickness direction of the fixing plate 11;

[0049] All the elastic sheets 1213 of the second clamping part 13 are divided into two groups: the elastic sheets 1213 of one group are aligned along the length direction of the fixed plate 11, and the elastic sheets 1213 of the other group are aligned along the length direction of the fixed plate 11. A second clamping space 131 for embedding the second male terminal 3 is formed between one side of one group of elastic sheets 1213 in the thickness direction of the fixed plate 11 and one side of the other group of elastic sheets 1213 in the thickness direction of the fixed plate 11.

[0050] The present invention provides a high-current connection structure. Compared with the prior art, the spring terminal 1 can clamp the first male terminal 2 and the second male terminal 3 at the same time, and has a simple structure and low cost. The user can cut the fixed plate 11 into corresponding lengths along the length direction of the fixed plate 11 according to different working currents, so that the user does not need to redevelop molds to produce high-current connection structures with different working currents, which greatly reduces the production cost of the high-current connection structure and meets the different needs of customers. When the high-current connection structure needs to be installed, it is only necessary to clamp the first male terminal 2 in the first clamping space 121 and the second male terminal 3 in the second clamping space 131, which is very convenient.

[0051] For further information, please also refer to Figure 3 , Figure 4 and Figure 5 As a specific embodiment of a high current connection structure provided by the present invention, each elastic sheet 1213 includes a first plate 12131 and a second plate 12132 fixed on one end of the first plate 12131, one end of each first plate 12131 away from the second plate 12132 is fixed on the fixed plate 11 and is set as the first end 1213a of the elastic sheet 1213, and one end of the second plate 12132 away from the first plate 12131 is set as the second end 1213b of the elastic sheet 1213, and in any three elastic sheets 1213 arranged in sequence on the same side of the fixed plate 11: the second plates 12132 of adjacent elastic sheets 1213 are spaced apart in the thickness direction of the fixed plate 11, and the second plates 12132 of two non-adjacent elastic sheets 1213 are aligned along the length direction of the fixed plate 11,

[0052] The second plate 12132 corresponding to the first clamping portion 12 is in contact with the first male terminal 2;

[0053] The second plate 12132 corresponding to the second clamping portion 13 contacts the second male terminal 3 .

[0054] The elastic sheet 1213 has a simple structure and is easy to stamp. The second plate 12132 corresponding to the first clamping portion 12 contacts the first male terminal 2, reducing the influence of the first male terminal 2 on the first plate 12131 corresponding to the first clamping portion 12, and improving the service life of the elastic sheet 1213 corresponding to the first clamping portion 12. The second plate 12132 corresponding to the second clamping portion 13 contacts the second male terminal 3, reducing the influence of the second male terminal 3 on the first plate 12131 corresponding to the second clamping portion 13, and improving the service life of the elastic sheet 1213 corresponding to the second clamping portion 13.

[0055] Furthermore, as a specific implementation of a high current connection structure provided by the present invention, the spring terminal 1 is configured as a stamped part formed by continuous stamping.

[0056] Manufacturers can produce spring terminals 1 of different lengths according to actual needs. Spring terminals 1 of different lengths correspond to different working currents, directly meeting the needs of users. Manufacturers can also produce spring terminals 1 of a certain length, and users can cut spring terminals 1 of corresponding lengths from spring terminals 1 of a certain length according to their own needs.

[0057] For further information, please also refer to Figure 3 , Figure 4 and Figure 5 As a specific embodiment of a high current connection structure provided by the present invention, a plurality of elastic sheets 1213 of the first clamping portion 12 are arranged at equal intervals along the length direction of the fixing plate 11;

[0058] The multiple elastic pieces 1213 of the second clamping portion 13 are arranged at equal intervals along the length direction of the fixing plate 11, which facilitates the mold opening and manufacturing of the large current connection structure and reduces the production cost of the large current connection structure.

[0059] For further information, please also refer to Figure 3 , Figure 4 and Figure 5 As a specific implementation of a high current connection structure provided by the present invention, the spring terminal 1 further includes a plurality of first guide plates 14, each of which corresponds to the elastic sheet 1213 one by one;

[0060] Each first guide plate 14 is fixed on one side of the corresponding elastic sheet 1213, arranged along the edge of the corresponding elastic sheet 1213 and located between the corresponding first end 1213a and the corresponding second end 1213b. The first guide plate 14 corresponding to the first clamping portion 12 is located outside the corresponding first clamping space 121, and the first guide plate 14 corresponding to the second clamping portion 13 is located outside the corresponding second clamping space 131. Each first guide plate 14 is inclined along the thickness direction of the corresponding elastic sheet 1213 from the side close to the corresponding elastic sheet 1213 to the side away from the corresponding elastic sheet 1213, so that the first guide plate 14 and the corresponding elastic sheet 1213 form a first structure 141 with a V-shaped cross-section, and the cross-sectional angle of the first structure 141 is preferably an obtuse angle.

[0061] When the user connects the first male terminal 2 to the high-current connection structure, the first male terminal 2 first contacts the first guide plate 14, and the first guide plate 14 guides the first male terminal 2 to the first clamping space 121 of the first clamping portion 12. Similarly, when the user connects the second male terminal 3 to the high-current connection structure, the second male terminal 3 slides from the side of the elastic sheet 1213 that fixes the first guide plate 14 into the second clamping space 131, and the second male terminal 3 first contacts the first guide plate 14, and the first guide plate 14 guides the second male terminal 3 into the second clamping space 131.

[0062] Specifically, a smooth transition is provided between the first guide plate 14 and the corresponding elastic sheet 1213 , ensuring that the first guide plate 14 guides the first male terminal 2 into the first clamping space 121 , and that the first guide plate 14 guides the second male terminal 3 into the inner side of the second clamping space 131 .

[0063] Optimally, an edge of the first guide plate 14 in the width direction is connected to an edge of the corresponding elastic sheet 1213 .

[0064] For further information, please also refer to Figure 3 , Figure 4 and Figure 5 As a specific embodiment of a high current connection structure provided by the present invention, the spring terminal 1 further includes a plurality of second guide plates 15, and a side of the elastic sheet 1213 away from the corresponding first guide plate 14 is set as a connection side (not shown in the figure);

[0065] Each second guide plate 15 corresponds to the elastic sheet 1213 one by one;

[0066] The second guide plate 15 is fixed on the corresponding connection side, arranged along the edge of the corresponding elastic sheet 1213, and located between the corresponding first end 1213a and the corresponding second end 1213b. The second guide plate 15 corresponding to the first clamping portion 12 is located outside the corresponding first clamping space 121, and the second guide plate 15 corresponding to the second clamping portion 13 is located outside the corresponding second clamping space 131. Each second guide plate 15 is inclined along the thickness direction of the corresponding elastic sheet 1213 from close to the corresponding connection side to away from the corresponding connection side, so that the second guide plate 15 and the corresponding elastic sheet 1213 form a second structure 151 with a V-shaped cross-section, and the cross-sectional angle of the second structure 151 is preferably an obtuse angle.

[0067] When the user connects the first male terminal 2 to the high-current connection structure, the first male terminal 2 will contact the second guide plate 15 during the process of sliding from the side of the elastic sheet 1213 where the second guide plate 15 is fixed to the inner side of the first clamping space 121, and the second guide plate 15 will guide the first male terminal 2 to the inner side of the first clamping space 121. Similarly, when the user connects the second male terminal 3 to the high-current connection structure, the second male terminal 3 will contact the second guide plate 15 during the process of sliding from the side of the elastic sheet 1213 where the second guide plate 15 is fixed to the inner side of the second clamping space 131, and the second male terminal 3 will contact the second guide plate 15, and the second guide plate 15 will guide the second male terminal 3 to the second clamping space 131.

[0068] Specifically, a smooth transition is provided between the second guide plate 15 and the corresponding elastic sheet 1213 , ensuring that the second guide plate 15 guides the first male terminal 2 to the inner side of the first clamping space 121 , and ensuring that the second guide plate 15 guides the second male terminal 3 to the inner side of the second clamping space 131 .

[0069] For further information, please also refer to Figure 3 , Figure 4 and Figure 5 As a specific embodiment of a high current connection structure provided by the present invention, the spring terminal 1 also includes a plurality of third guide plates 16, each of the third guide plates 16 corresponds to the elastic sheet 1213 one by one, and the third guide plates 16 are fixed on the edge of the corresponding second end 1213b. The third guide plates 16 corresponding to the first clamping portion 12 are located outside the corresponding first clamping space 121, and the third guide plates 16 corresponding to the second clamping portion 13 are located outside the corresponding second clamping space 131. Each third guide plate 16 is inclined along the thickness direction of the corresponding elastic sheet 1213 from the edge close to the corresponding second end 1213b to the edge away from the corresponding second end 1213b, so that the third guide plates 16 and the corresponding elastic sheet 1213 form a third structure 161 with a V-shaped cross-section, and the cross-sectional angle of the third structure 161 is preferably an obtuse angle.

[0070] When the user connects the first male terminal 2 to the high-current connection structure, the first male terminal 2 slides from the side of the elastic sheet 1213 where the third guide plate 16 is fixed to the inner side of the first clamping space 121, and the first male terminal 2 contacts the third guide plate 16, and the third guide plate 16 guides the first male terminal 2 to the inner side of the first clamping space 121. Similarly, when the user connects the second male terminal 3 to the high-current connection structure, the second male terminal 3 slides from the side of the elastic sheet 1213 where the third guide plate 16 is fixed to the inner side of the second clamping space 131, and the second male terminal 3 contacts the third guide plate 16, and the third guide plate 16 guides the second male terminal 3 to the inner side of the second clamping space 131. The first guide plate 14 cooperates with the corresponding second guide plate 15 and the corresponding third guide plate 16, so that the first male terminal 2 can be clamped on the high-current connection structure from three different directions of the first clamping portion 12, and the second male terminal 3 can be clamped on the high-current connection structure from three different directions of the second clamping portion 13, thereby improving the convenience of using the high-current connection structure. The elastic sheet 1213 is integrally stamped with the corresponding first guide plate 14, the corresponding second guide plate 15, and the corresponding third guide plate 16.

[0071] Specifically, a smooth transition is provided between the third guide plate 16 and the corresponding elastic sheet 1213 , ensuring that the third guide plate 16 guides the first male terminal 2 to the inner side of the first clamping space 121 , and ensuring that the second guide plate 15 guides the second male terminal 3 to the inner side of the second clamping space 131 .

[0072] Furthermore, as a specific implementation of a high current connection structure provided by the present invention, the third guide plate 16 is connected to the corresponding first guide plate 14 with a smooth transition, thereby improving the stability of the third guide plate 16 and the corresponding first guide plate 14 being fixed to the corresponding elastic sheet 1213 .

[0073] Furthermore, as a specific implementation of a high current connection structure provided by the present invention, the third guide plate 16 is connected to the corresponding second guide plate 15 with a smooth transition, thereby improving the stability of the third guide plate 16 and the corresponding second guide plate 15 being fixed to the corresponding elastic sheet 1213.

[0075] The first connecting plate 41 is fixed on one side of the fixing plate 11 in the thickness direction;

[0076] The first elastic sheet 42 is fixed on the first connecting plate 41 , and the first elastic sheet 42 avoids the first male terminal 2 and the second male terminal 3 ;

[0077] All the first spring sheets 42 are divided into two groups; one group of first spring sheets 42 is located on an outer side of the first clamping space 121, and corresponds one-to-one to each elastic sheet 1213 located on the same side of the first clamping space 121, and contacts the side of the elastic sheet 1213 facing away from the first clamping space 121; the other group of first spring sheets 42 is located on the outer side of the second clamping space 131, and corresponds one-to-one to and contacts each elastic sheet 1213 located on the same side of the second clamping space 131, and contacts the side of the elastic sheet 1213 facing away from the second clamping space 131; the elastic force of each first spring sheet 42 of one group of first spring sheets 42 is toward the first clamping space 121, and the elastic force of each first spring sheet 42 of the other group of first spring sheets 42 is toward the second clamping space 131.

The first elastic piece 42 avoids the first male terminal 2 and the second male terminal 3, reducing the influence of the first elastic piece 42 on the first male terminal 2 and the second male terminal 3.

[0079] Specifically, in the continuous stamping process, a corresponding continuous stamping die is used to form a first sheath 4 of continuous length, and the first sheath 4 of continuous length is cut according to the length of the spring terminal 1 .
