[0037] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. The described implementation is a part of the implementation of the utility model, not all of the implementations.
[0038] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.
[0039] Example 1
[0040] refer to Figures 1 to 3 The floating high current connector provided by the utility model comprises a male socket unit 1 and a female socket unit 2, which are plugged into each other. Specifically, the female socket unit 2 comprises a female socket housing 21, a plurality of female socket power terminals 22 and a plurality of female socket signal terminals 23, and the female socket power terminals 22 and the female socket signal terminals 23 are both mounted on the female socket housing 21. The female socket power terminals 22 are used to realize current transmission, and the female socket signal terminals 23 are used to realize signal transmission.
[0041] Furthermore, the female power terminal 22 includes a connecting portion 221, a floating portion 222 and a fixing portion 223 connected in sequence. The connecting portion 221 is electrically connected to the male unit 1, the floating portion 222 can meet the floating requirements during assembly and absorb the tolerance during assembly, and the fixing portion 223 is used for welding on the circuit board.
[0042] Furthermore, the floating portion 222 is provided with a gap 2221 along the length direction, and the two ends of the gap 2221 are respectively connected to the connecting portion 221 and the fixing portion 223. It can be understood that the gap 2221 covers the entire length direction of the floating portion 222, and in some embodiments, the gap 2221 can be one or more. By providing the gap 2221 in the floating portion 222 of the female power terminal 22, on the one hand, the stress of the female power terminal 22 when floating can be dispersed, so that the female power terminal 22 can quickly return to its original state after the floating ends, and stable connection and transmission can be achieved; on the other hand, the provision of the gap 2221 is also conducive to improving the current transmission rate and realizing high current transmission of the connector.
[0043] Furthermore, the floating portion 222 forms a plurality of first bends 2222 along the first direction X, and the floating portion 222 forms a plurality of second bends 2223 along the second direction Y, and the first direction X and the second direction Y are perpendicular to each other. It can be understood that the plurality of first bends 2222 formed along the first direction X are on the same plane, and the plurality of second bends 2223 formed along the second direction Y are on another plane, and the plane where the first bends 2222 are located is perpendicular to the plane where the second bends 2223 are located.
[0044] By forming a plurality of first bends 2222 and a plurality of second bends 2223 respectively along the first direction X and the second direction Y, it is possible to simultaneously provide the female power terminal 22 with floating spaces in two different directions, so that the female power terminal 22 has a larger floating range during assembly, which can float ±0.80mm, better absorb the tolerance during assembly, and achieve stable current transmission. At the same time, the plurality of first bends 2222 and the plurality of second bends 2223 formed along different directions can also significantly improve the current transmission rate, so that the female power terminal 22 can carry large currents and meet the transmission requirements of large currents.
[0045] Example 2
[0046] As a further optimization of Example 1, continue to refer to Figures 1 to 3 , and refer to Figure 4 The connection between the floating part 222 and the fixed part 223 is at a right angle. On the basis that the floating part 222 forms a plurality of first bends 2222 and a plurality of second bends 2223 along the first direction X and the second direction Y, respectively, the right-angle structure formed between the floating part 222 and the fixed part 223 can further increase the current transmission rate, so that the connector can achieve stable high current transmission, and the current that the female power terminal 22 can carry can be as high as 5A.
[0047] As a further optimization, the bending angles of the first bend 2222 and the second bend 2223 are both obtuse angles. The first bend 2222 and the second bend 2223 with obtuse bending angles can provide space for the floating of the female power terminal 22 to be stretched and extended, and are more conducive to recovery after the floating ends. In some embodiments, the bends of the first bend 2222 and the second bend 2223 can be formed with rounded corners, and it can also be understood that the first bend 2222 and the second bend 2223 are both arc-shaped bends. The rounded corner structure can disperse the stress of the female power terminal 22 when it floats, so that the female power terminal 22 can quickly return to its original state after the floating ends, thereby achieving rapid assembly and stable connection.
[0048] As a further optimization, the mother socket signal terminal 23 is formed with a plurality of third bends 231, and the bending angle of the third bend 231 is an obtuse angle. Similarly, the plurality of third bends 231 formed by the mother socket signal terminal 23 can provide more elongated and extended space for the floating of the mother socket signal terminal 23, and the bending angle of the obtuse angle is more conducive to recovery after the floating is completed. In some embodiments, the bending part of the third bend 231 is formed with a rounded corner, which can also be understood as the third bend 231 is an arc-shaped bend. Similarly, the rounded corner can disperse the stress of the mother socket signal terminal 23 when it floats, which is conducive to rapid recovery after the floating is completed.
[0049] With the floating space provided by the first bend 2222, the second bend 2223 and the third bend 231, the male unit 1 and the female unit 2 can be inserted shallowly or deeply by 0.60mm when mating with each other. That is, it can be understood that when the minimum mating height of the male unit 1 and the female unit 2 is 26.0mm, the maximum mating height can reach 26.60mm, thereby making the connector more versatile and inclusive.
