[0043] Please refer to Figures 1 to 10The utility model discloses an electrical connector assembly 100, which includes a first electrical connector component 1, a second electrical connector component 2, a sealing member 4 and a fixing member 3. The first electrical connector component 1 includes a first circuit board 11 and a first electrical connector 12 disposed on the first circuit board 11. The second electrical connector component 2 includes a second circuit board 21 located above the first circuit board 11 and a second electrical connector 22 disposed on the second circuit board 21, and the first electrical connector 12 and the second electrical connector 22 can be docked together. The sealing member 4 is disposed between the first circuit board 11 and the second circuit board 21, and the sealing member 4 and the first circuit board 11 and the second circuit board 21 are surrounded to form a sealed cavity, and the first electrical connector 12 and the second electrical connector 22 are disposed in the sealed cavity. The fixing member 3 is disposed above the second circuit board 21, and the middle part of the fixing member 3 abuts against the second circuit board 21, and the fixing member 3 presses downward on the second circuit board 21 and is connected to the first circuit board 11. In this way, the sealing cavity is formed by the sealing member 4, the first circuit board 11 and the second circuit board 21, and the first electrical connector 12 and the second electrical connector 22 are arranged in the sealing cavity, which can achieve a good waterproof effect on the first electrical connector 12 and the second electrical connector 22. By connecting the fixing member 3 to the first circuit board 11, the fixing member 3 can apply downward pressure to the second circuit board 21, so that the sealing member 4 and the first circuit board 11, the second circuit board 21 are more tightly combined, further improving the waterproof performance, and also improving the stability of the first electrical connector 12 and the second electrical connector 22 when docking.

[0044] Specifically, the seal 4 is annular, and the seal 4 is arranged around the outer periphery of the first electrical connector 12 and the second electrical connector 22, and the size of the seal 4 is adapted to the size of the first electrical connector 12. The seal 4 is a hollow rectangular shape, and the seal 4 is foam, and the seal 4 has a certain compression rate. In this embodiment, the thickness T of the seal 4 is greater than the thickness when the first electrical connector 12 and the second electrical connector 22 are docked. Preferably, the length L of the seal 4 is 6.5mm, the width W is 4mm, and the thickness T is 0.7mm. Of course, the size of the seal 4 and the compression rate of the seal 4 itself can be set according to the size of the first electrical connector 12 and the second electrical connector 22, and are not limited here. When the fixing member 3 is fixedly connected to the first circuit board 11, the seal 4 is sealed and connected to the first circuit board 11 and the second circuit board 21 on the upper and lower sides due to the action of the fixing member 3, so as to achieve a waterproof effect.

[0045] Please refer to Figure 2 The sealing member 4 and the first circuit board 11 are fixed by bonding, which facilitates the assembly of the electrical connector assembly 100 and improves the assembly efficiency.

[0046] Please refer to Figures 2 to 7The fixing member 3 includes a main body 31 and positioning parts 32 disposed on opposite sides of the main body 31. The main body 31 is pressed against the second circuit board 21, and the two positioning parts 32 are connected to the first circuit board 11.

[0047] The electrical connector assembly 100 further includes at least one elastic member 5, which is disposed between the second circuit board 21 and the main body 31. The elastic member 5 can prevent the fixing member 3 from scratching the surface of the second circuit board 21 when in frictional contact with the second circuit board 21, thereby affecting the conductive performance of the second circuit board 21. At the same time, the elastic member 5 itself has a certain compression rate, and can also apply downward pressure to the second circuit board 21, thereby improving the stability of the first electrical connector 12 and the second electrical connector 22 when they are connected.

[0048] The fixing member 3 also includes two bending portions 33, each of which is connected to the main body 31 at a first end, and connected to the positioning portion 32 at the other end. Specifically, the two positioning portions 32 are arranged on opposite sides of the main body 31 along the first direction D1-D1 of the main body 31, and the bending portion 33 is extended along the second direction D2-D2, and the first direction D1-D1 is perpendicular to the second direction D2-D2. The main body 31 and the positioning portion 32 are arranged in a staggered manner in the second direction D2-D2 by the bending portion 33. When the fixing member 3 is fixedly connected to the first circuit board 11, the main body 31, the two bending portions 33 and the first circuit board 11 form a receiving space, and the first electrical connector 12, the second electrical connector 22, the second circuit board 21 and the elastic member 5 are all arranged in the receiving space 302. At this time, the elastic member 5 can apply pressure to the first electrical connector 12 on the second electrical connector 22, thereby improving the stability of the first electrical connector 12 and the second electrical connector 22 when docking.

[0049] Please refer to Figure 4 In this embodiment, the elastic member 5 is a two-layered elastic member 5, which is stacked up and down to prevent the main body 31 from being directly pressed on the second circuit board 21 and causing damage to the second circuit board 21 and the second electrical connector 22. The elastic member 5 is a foam, which has a compression rate. When the fixing member 3 is fixedly connected to the first circuit board 11, the elastic member 5 can elastically abut the second circuit board 21. At the same time, the elastic member 5 exerts downward pressure on the second circuit board 21 by releasing its own compression force, so that the second electrical connector 22 can be more stable when docking with the first electrical connector 12. Preferably, the elastic member 5 is glued and fixed to the main body 31 to facilitate the positioning of the elastic member 5 on the main body 31.

[0050] Please refer to Figures 2 to 3, two positioning posts 111 are provided on the first circuit board 11, and the two positioning posts 111 are respectively arranged on both sides of the first electrical connector 12, and the two positioning posts 111 are arranged in a one-to-one correspondence with the two positioning parts 32, and the positioning parts 32 are connected to the positioning posts 111. Specifically, the two positioning posts 111 are respectively arranged on both sides of the first electrical connector 12 along the first direction D1-D1. In this embodiment, the positioning part 32 has a first positioning hole 301, the positioning post 111 has a second positioning hole 101, and the fixing member 3 also includes a fastener, which passes through the first positioning hole 301 and is connected to the second positioning hole 101 to fix the fixing member 3 to the first circuit board 11. In other embodiments, the positioning part 32 is connected to the positioning post 111 by gluing, which can also achieve the purpose of fixing the fixing member 3 to the first circuit board 11.

[0051] The utility model also discloses an electronic device, which includes an electrical connector assembly 100. The electronic device in this embodiment includes but is not limited to a wireless Bluetooth headset, a mobile phone, a tablet computer, a laptop computer, a smart watch, etc. By using the electrical connector assembly 100 disclosed in the utility model in an electronic device, the waterproof performance of the electronic device is improved, thereby improving the user experience.

[0052] In summary, the electrical connector assembly 100 of the utility model includes a first electrical connector component 1, a second electrical connector component 2, a sealing member 4 and a fixing member 3. The first electrical connector component 1 includes a first circuit board 11 and a first electrical connector 12 disposed on the first circuit board 11. The second electrical connector component 2 includes a second circuit board 21 and a second electrical connector 22 disposed on the second circuit board 21, and the first electrical connector 12 is docked with the second electrical connector 22. The fixing member 3 is disposed above the second circuit board 21. By abutting the middle part of the fixing member 3 with the second circuit board 21 and connecting the two ends of the fixing member 3 with the first circuit board 11, the fixing member 3 can apply downward pressure to the second circuit board 21, thereby avoiding the separation of the first electrical connector 12 and the second electrical connector 22 when the sealing member 4 applies an upward elastic force to the second circuit board 21, thereby improving the stability of the first electrical connector 12 and the second electrical connector 22 when docking.
