[0021] To address the issue of poor current carrying capacity of existing connector terminals, this invention provides a stacked 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 stacked board-to-board high-current connector, including multiple male end brackets 1 and female end brackets 2. Multiple terminal brackets 4 are fixedly connected to the inner side of both the male end brackets 1 and the female end brackets 2. Multiple single-layer terminals 5 and double-layer terminals 6 are fixedly inserted into the interior of each terminal bracket 4.

[0024] Multiple terminal brackets 4 can be fixedly connected between the two male brackets 1 according to power requirements and connector specifications. The fixed configuration of the male brackets 1 and terminal brackets 4 forms a male connector. Multiple terminal brackets 4 can be fixedly connected between the two female brackets 2. The fixed configuration of the female brackets 2 and terminal brackets 4 forms a female connector. The male connector and the female connector can be mated to form a complete high-current connector structure.

[0025] In some embodiments, positioning boxes 101 are fixedly connected to the upper two sides of the male end bracket 1, positioning posts 21 are fixedly connected to the upper two sides of the female end bracket 2, a slot 1011 is opened at the lower end of the interior of the positioning box 101, and a snap-fit ​​plate 22 is fixedly connected to the lower end of the positioning post 21.

[0026] Please see Figure 2 The positioning box 101 has a cylindrical receiving groove on one side, and the slot 1011 is located at the bottom of the receiving groove. When the male connector and the female connector are mated, the positioning post 21 is inserted into the inside of the positioning box 101 to realize the positioning and mating of the male connector and the female connector. This makes it convenient for users to mate the connectors normally even when blindly mating. At the same time, the snap plate 22 below the positioning post 21 slides into the slot 1011 during mating to prevent the male connector and the female connector from rotating after mating.

[0027] In some embodiments, a circuit board 3 is fixedly connected to the bottom of both the male end bracket 1 and the female end bracket 3. The circuit board 3 is mainly used to receive and process electronic signals.

[0028] In some embodiments, the terminal bracket 4 has a placement groove 41 inside, and a plurality of partitions 42 are fixedly connected between the placement grooves 41.

[0029] The placement groove 41 extends from one end of the terminal bracket 4 to the outside of the terminal bracket 4. The interior of the placement groove 41 is also provided with a connecting buckle or protrusion for locking the terminal. When assembling the male connector and the female connector, the terminal can be slid into the interior of the placement groove 41 and locked in the placement groove 41. At the same time, the multiple partitions 42 can separate the terminals to prevent the terminals from directly contacting each other and causing current short circuits.

[0030] Please see Figure 3 In some embodiments, a limiting arm 51 is fixedly connected to the upper end of the single-layer terminal 5, and a protrusion 52 is fixedly connected to the side of the single-layer terminal 5.

[0031] When the single-layer terminal 5 is installed inside the placement slot 41 of the terminal bracket 4, the single-layer terminal 55 is fixedly installed by the limiting force arm 51 and the protrusion 52 set in the single-layer terminal 5 being engaged with the connecting buckle and other engaging structures set in the placement slot 41.

[0032] In some embodiments, the double-layer terminal 6 is composed of an outer layer terminal 61 and an inner layer terminal 62. The outer layer terminal 61 has a positioning hole 63 on its side, and an outer layer pin 64 is fixedly connected to the front end of the outer layer terminal 61. An inner layer pin 65 is fixedly connected to the front end of the inner layer terminal 62.

[0033] The inner terminal has a positioning pin on its side. The outer terminal 61 is connected to the positioning pin of the inner terminal 62 through the positioning hole 63, so that the inner terminal 62 and the outer terminal 61 can be fixedly connected. The outer pin 64 and the inner pin 65 are located at the front end of the terminal and are staggered to form two rows of parallel pins.

[0034] Please see Figure 4 A segmented slit 621 is provided in the middle of the surface of the inner terminal 62, and a bent portion 622 is provided at the middle end of the inner terminal 62.

[0035] The inner terminal 62 is bent and torn in the middle by opening a segmented seam 621, and the bending treatment is performed in the middle position of the inner terminal 62 to ensure that the male connector contact and the two overlapping terminals of the female connector are in contact, and the number of contact points is consistent. This can effectively ensure the consistency and uniformity of the current, and better solve the damage to the connector caused by high heat due to uneven current.

[0036] In this invention, during assembly, the male connector and the female connector are fixed by a terminal bracket 4 fixedly snapped between the male connector bracket 1 and the female connector bracket 2. Then, the single-layer terminal 5 and the double-layer terminal 6 are fixedly snapped into the placement groove 41 by the set limiting force arm 51 and protrusion 52 and other structures. The assembly of the male connector and the female connector can be completed. Then, when in use, the positioning post 21 and the positioning box 101 can realize the positioning connection of the male connector and the female connector.

[0037] 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.
