[0021] To address the issues described in the background section, this invention provides a board-to-board high-current connector.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 This utility model provides a board-to-board high-current connector, including a male connector plastic body bracket 1 and a female connector plastic body bracket 2. Multiple metal terminals 4 are fixedly snapped between the male bracket 1 and the female bracket 2. The lower ends of the metal terminals of the male connector 1 and the female connector 2 are soldered to the circuit board 3.

[0024] The male terminal bracket 1 and multiple terminal brackets 4 can be spliced ​​together to form the male terminal structure of the connector, and the female terminal bracket 2 and multiple terminal brackets 4 can be spliced ​​together to form the female terminal structure of the connector. The circuit board 3 is fixedly inserted into the lower end of the male terminal connector and the female terminal connector, and is mainly used for transmitting signals and current.

[0025] In some embodiments, guide holes 101 are provided on both sides of one end of the male end bracket 1, threaded holes 21 are provided on the surface of the female end bracket 2, guide posts 22 are fixedly connected to the front end mating surface of the female end bracket 2, and positioning posts 23 are fixedly connected to the lower end of the female end bracket 2.

[0026] The front end of the guide post 22 is designed as a semi-circular structure. There are three guide posts 22 and three guide holes 101, located in the middle and on both sides of the male end of the connector. When the male end of the connector and the female end of the connector are mated, the guide post 22 can be easily slid into the corresponding guide hole 101 to realize the mating of the male end of the connector and the female end of the connector.

[0027] Please see Figure 2 In some embodiments, the connecting surface of the terminal bracket 4 is provided with a placement groove 41, and the signal terminal 5 and the terminal module 6 can be movably inserted into the placement groove 41. The upper end of the terminal module 6 is fixedly connected to a limiting arm 61. When the terminal module 6 is inserted into the terminal bracket 4 through the placement groove 41, the terminal can be fixedly assembled by being snapped into the interior of the terminal bracket 4 by the limiting arm 61.

[0028] Please see Figure 3In some embodiments, a twist pin 51 is fixedly connected to the rear end of the signal terminal 5, and a protrusion 52 is provided on the rear end surface of the signal terminal 5. The signal terminal 5 uses a stamping twist pin process, that is, the part is rotated 90 degrees during the stamping design to ensure that the contact point of the female connector signal terminal contacts the surface of the male connector signal terminal in the material thickness direction, rather than contacting the stamped and sheared surface, thus ensuring stable and reliable contact. At the same time, when the signal terminal 5 is inserted into the interior of the terminal bracket 4, the protrusion 52 at the rear end is engaged in the inner wall of the placement groove 41, which serves to fix the signal terminal 5.

[0029] Please see Figure 4 In some embodiments, the rear end of the terminal bracket 4 is provided with a plurality of limiting strips 42 on the inner wall of the placement groove 41. The limiting strips 42 play an auxiliary supporting role when the terminal module 6 is inserted into the terminal bracket 4. The circuit board 3 has positioning holes 31 on both sides, and the positioning pins 23 can be inserted into the positioning holes 31 to realize the connection between the male connector bracket 1 and the circuit board 3.

[0030] like Figure 5 As shown, in some embodiments, the middle contact arm of the terminal of the front end of one side terminal of the terminal module 6 is lower than that of the two sides, and the middle contact point is lower than that of the two sides. When the male and female connectors are assembled, the two sides of the terminal contact point contact first, and the middle contact point contact later, thereby realizing the segmented contact sequence and time difference to reduce the insertion force of the male and female connectors to mate.

[0031] When using this utility model, during the assembly of the connector, multiple terminal brackets 4, male terminal bracket 1, and female terminal bracket 2 are respectively snapped together to form the basic frame of the male and female terminals of the connector. The male terminal bracket and multiple terminal brackets 4 can be spliced ​​together to form the male terminal structure of the connector, and the female terminal bracket and multiple terminal brackets 4 can be spliced ​​together to form the female terminal structure of the connector. This realizes the modular structure of the male and female terminals of the connector, which facilitates the assembly of the connector and increases the current structure of the connector. The connector structure can be assembled according to different distances and different power requirements. Then, the signal terminal 5 and the terminal module 6 are inserted into the inside of the placement slot 41 and are snapped and fixed with the terminal bracket 4 by the protrusion 52 and the limiting force arm 61 to realize the installation of the terminal. When the male and female connectors are in use, the guide post 22 can be easily slid into the corresponding guide hole 101 to realize the docking of the male and female terminals of the connector.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
