However, due to the small internal space of the electronic device and other reasons, the circuit boards and main boards corresponding to the input and output interfaces usually need to be staggered up and down, which requires connecting the circuit boards and main boards corresponding to the input and output interfaces.

[0003] In order to solve the above problems, the existing technology mainly uses a combination of flat flexible cable (FFC, Flexible Flat Cable) and zero insertion force connector (ZIF, Zero Insertion Force) to connect the circuit board corresponding to the input and output interface with the mainboard, but this method is costly and cannot be assembled automatically. Utility Model Content

[0004] The present disclosure provides a board-to-board connector and an electronic device to at least solve the above technical problems existing in the prior art.

[0005] According to a first aspect of the present disclosure, a board-to-board connector is provided, the board-to-board connector comprising: a female connector, the female connector comprising a female end body and a female end terminal, the female end body comprising a first main body portion and a second main body portion, the bottom surfaces of the first main body portion and the second main body portion are connected, and the height of the second main body portion is greater than the height of the first main body portion; a portion of the female end terminal is arranged inside the female end body, and another portion of the female end terminal leaks out of the female end body; a male connector, the male connector comprising a male end body and a male end terminal, the male end body comprising a third main body portion and a fourth main body portion, the bottom surfaces of the third main body portion and the fourth main body portion are connected, and the height of the fourth main body portion is greater than the height of the third main body portion; a portion of the male end terminal is arranged inside the male end body, and another portion of the male end terminal leaks out of the male end body.

[0006] In one possible implementation manner, the female terminal includes a first terminal portion and a second terminal portion, the first terminal portion is horizontally arranged inside the first main body portion, and the second terminal portion extends along a height change direction of the second main body portion until it leaks out of the second main body portion.

[0007] In one possible implementation manner, the male terminal includes a third terminal portion and a fourth terminal portion, the third terminal portion is horizontally arranged outside the third main body portion, the fourth terminal portion is horizontally arranged outside the fourth main body portion, and the third terminal portion is connected to the fourth terminal portion.

[0008] In one possible implementation manner, the female end of the connector is movably connected to the male end of the connector, and when the female end of the connector and the male end of the connector are in a connected state, the second terminal portion touches the third terminal portion, or the second terminal portion touches the fourth terminal portion.

[0009] In one possible implementation manner, the connector female end is snap-connected to the connector male end.

[0010] In one possible implementation manner, the second main body is provided with a card hole, the fourth main body is provided with a protrusion, and the female end of the connector and the male end of the connector are snap-connected via the card hole and the protrusion.

DETAILED DESCRIPTION

[0030] In order to make the purpose, features, and advantages of the present disclosure more obvious and easy to understand, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0031] Figure 2 The structure of a board-to-board connector according to an embodiment of the present disclosure is shown. Figure 1 ; Figure 3 The structure of a board-to-board connector according to an embodiment of the present disclosure is shown. Figure 2 ; Figure 4 The structure of a board-to-board connector according to an embodiment of the present disclosure is shown. Figure 3 ; Figure 5 The structure of a board-to-board connector according to an embodiment of the present disclosure is shown. Figure 4 ,like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a board-to-board (BTB) connector includes:

[0032] The female connector includes a female body and a female terminal 20. The female body includes a first body portion 10 and a second body portion 30. The bottom surfaces of the first body portion 10 and the second body portion 30 are connected. The height of the second body portion 30 is greater than the height of the first body portion 10. A part of the female terminal 20 is arranged inside the female body, and another part of the female terminal 20 leaks out of the female body.

[0033] The male end of the connector includes a male end body and a male terminal 50. The male end body includes a third body part 40 and a fourth body part 60. The bottom surfaces of the third body part 40 and the fourth body part 60 are connected. The height of the fourth body part 60 is greater than the height of the third body part 40. A part of the male terminal 50 is arranged inside the male end body, and another part of the male terminal 50 leaks out of the male end body.

[0034] In this embodiment, the height of the second body portion 30 of the female end body of the BTB connector is greater than the height of the first body portion 10, that is, the female end of the BTB connector is in a step shape. Similarly, the height of the fourth body portion 60 of the male end body of the BTB connector is greater than the height of the third body portion 40, that is, the male end of the BTB connector is also in a step shape. The height difference between the second body portion 30 and the first body portion 10 and the height difference between the fourth body portion 60 and the third body portion 40 are the step height. The step height of the BTB connector can be set based on the height difference between the circuit board and the mainboard corresponding to the input and output interface that the BTB connector needs to connect. That is, the BTB connector is suitable for various types of electronic devices, has good flexibility, and is lower in cost than the connection method combining FFC and ZIF.

[0035] In one embodiment, the female terminal 20 includes a first terminal portion 21 and a second terminal portion 22, wherein the first terminal portion 21 is horizontally disposed inside the first main body portion 10, and the second terminal portion 22 extends along the height change direction of the second main body portion 30 until it leaks out of the second main body portion 30. One end of the female terminal 20 leaks out of the first main body portion 10, and then a portion of the first terminal portion 21 is horizontally disposed inside the first main body portion 10, and then a portion of the second terminal portion 22 extends along the height change direction of the second main body portion 30 until it leaks out of the second main body portion 30, and then it can be re-extended to the inside of the second main body portion 30, thereby increasing the fixity of the female terminal 20. It can be seen that the portion of the female terminal 20 corresponding to the second main body portion 30 can be in a "V" shape.

[0036] In one embodiment, the male terminal 50 includes a third terminal portion 51 and a fourth terminal portion 52, wherein the third terminal portion 51 is horizontally disposed outside the third body portion 40, and the fourth terminal portion 52 is horizontally disposed outside the fourth body portion 60, and the third terminal portion 51 is connected to the fourth terminal portion 52. One end of the male terminal 50 leaks out of the third body portion 40, and then a portion of the third terminal portion 51 is horizontally disposed outside the third body portion 40, and then extends upward in the direction of the step until it reaches the outside of the fourth body portion 60, and is horizontally disposed along the outside of the fourth body portion 60. The end of the male terminal 50 can also be embedded in the fourth body portion 60 to increase the fixity of the male terminal 50.

[0037] In one embodiment, the female connector is movably connected to the male connector. When the female connector is in a connected state, the second terminal portion 22 is in contact with the third terminal portion 51, or the second terminal portion 22 is in contact with the fourth terminal portion 52. When the female connector is in a connected state, the second terminal portion 22 of the female terminal 20 that leaks out of the second body portion 30 is in contact with the third terminal portion 51 of the male terminal 50. Figure 7or, the second terminal portion 22 of the female terminal 20 that leaks out of the second main body portion 30 contacts the fourth terminal portion 52 of the male terminal 50, as shown in FIG. Figure 8 shown.

[0038] In one embodiment, the female end of the connector is snap-connected with the male end of the connector. The second body portion 30 is provided with a snap hole, and the fourth body portion 60 is provided with a protrusion 70. The female end of the connector is snap-connected with the male end of the connector through the snap hole and the protrusion. Figure 6 As shown in the figure, the connection between the female end of the connector and the male end of the connector using the snap-on structure is more stable, and automated assembly can be used, which can reduce manpower and further reduce costs.

[0039] In one embodiment, the height difference between the second main body 30 and the first main body 10 is 0.5 mm (millimeter), and the height difference between the fourth main body 40 and the third main body 30 is 0.5 mm. Figure 7 As shown, the height of the straight line L1 represents the height difference between the circuit board corresponding to the input and output interface and the main board, the height of the straight line L2 represents the step height of the BTB connector, that is, the height difference between the second body part 30 and the first body part 10 and the height difference between the fourth body part 60 and the third body part 40, and the height of the straight line L3 is the interference between the female end of the connector and the male end of the connector. In an example, the height of the straight line L1 can be 1.5mm, the height of the straight line L2 can be 0.5mm, and the height of the straight line L3 can be 0.25mm to 0.5mm.

[0040] like Figure 8 As shown, the height of the straight line L4 represents the height difference between the circuit board corresponding to the input and output interface and the main board, and the height of the straight line L5 represents the interference between the female end of the connector and the male end of the connector. In one example, the height of the straight line L4 can be 2 mm, the height of the straight line L5 can be 0.25 mm to 0.5 mm, and the step height is still 0.5 mm.
