Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0081] like Figures 1 to 10 As shown, an embodiment of the present invention provides a battery pack database file port connector, comprising:

[0082] A fixing member 1 is connected to the surface of the housing cover 71 and is a frame-shaped structure;

[0083] The floating sealing ring 2 includes a rectangular sealing ring 21, an upper flat sealing ring 22 is formed on the upper edge of the rectangular sealing ring 21, and a bottom flat sealing ring 23 is formed on the bottom edge of the rectangular sealing ring 21. The bottom flat sealing ring 23 is connected to the fixing member 1;

[0084] The floating member 31 has a bottom surface connected to the upper plane sealing ring 22; the floating member 31 has a floating amount in a preset direction;

[0085] A connecting cover plate 41 connected to the surface of the floating member 31;

[0086] a removable cover plate 42 connected to the center of the connecting cover plate 41;

[0087] A first connection terminal 43 connected to the battery pack database file port is disposed within a first housing 423 of the removable cover 42. The bottom surface of the first connection terminal 43 extends through the floating member 31 and abuts against a first copper busbar 74 within the connection housing 72. The center hole of the first connection terminal 43 is coaxial with the center hole of the first copper busbar 74.

[0088] A second connection terminal 44 connected to the battery pack database file port is disposed within a second housing 424 of the removable cover 42. The bottom surface of the second connection terminal 44 extends through the floating member 31 and abuts against a second copper busbar 75 within the connection housing 72. The center hole of the second connection terminal 44 is coaxial with the center hole of the second copper busbar 75.

[0089] The shielding shell 5 is connected to the bottom surface of the floating part 31. The first copper bar 74 and the second copper bar 75 are both located inside the shielding shell 5. A first elastic contact 51 is formed at the bottom of the shielding shell 5, and the first elastic contact 51 abuts against the chassis cover 71. A second elastic contact 53 is formed on the upper part of the shielding shell 5, and the second elastic contact 53 passes through the surface of the floating part 31 and abuts against the connecting cover 41.

[0090] In this embodiment, since the bottom plane sealing ring 23 is connected to the fixed part 1, and the bottom surface of the floating part 31 is connected to the upper plane sealing ring 22, the floating part 31 can be floated through the elastic deformation of the rectangular sealing ring 21. Specifically, with the length direction of the rectangular sealing ring 21 as the first direction, the floating part 31 can be floated in the first direction, thereby realizing the position adjustment of the floating part 31 along the first direction; with the width direction of the rectangular sealing ring 21 as the second direction, the floating part 31 can be floated in the second direction, thereby realizing the position adjustment of the floating part 31 along the second direction; with the height direction of the rectangular sealing ring 21 as the third direction, the floating part 31 can be floated in the third direction, thereby realizing the position adjustment of the floating part 31 along the third direction, thereby realizing the multi-directional position adjustment of the floating part 31. In specific applications, the floating amount of the floating part 31 in the three directions is greater than 2.7 mm.

[0091] The connecting housing 72 is connected to the outer shell 82 of the battery pack. After the battery pack is installed, there is a deviation and misalignment between the actual positions of the first connecting terminal 43 and the second connecting terminal 44 and the connecting threaded holes of the communication connection interface. Since the connecting cover 41 is connected to the floating member 31, the position adjustment of the connecting cover 41 and the position adjustment of the removable cover 42 can be achieved through the multi-directional position adjustment of the floating member 31, and ultimately the position adjustment of the first connecting terminal 43 and the second connecting terminal 44 is achieved, so that the center holes of the first connecting terminal 43 and the second connecting terminal 44 are coaxial with the connecting threaded holes of the communication connection interface, so that bolts are used to sequentially penetrate the center holes of the first copper busbar 74 and the first connecting terminal 43, as well as the center holes of the second copper busbar 75 and the second connecting terminal 44, and are threadedly connected to the connecting threaded holes of the communication connection interface.

[0092] The rectangular sealing ring 21 of the floating sealing ring 2 can realize the position adjustment of the floating member 31 in multiple directions, realize the position adjustment of the first connection terminal 43 and the second connection terminal 44, ensure the connection accuracy, and make the connection operation simple and convenient, which helps to improve production efficiency.

[0093] By disposing a shielding shell 5 on the bottom surface of the floating member 31, and with the first copper bar 74 and the second copper bar 75 both located inside the shielding shell 5, a first elastic contact 51 is formed on the bottom of the shielding shell 5, which abuts against the housing cover 71, and a second elastic contact 53 is formed on the top of the shielding shell 5, which penetrates the surface of the floating member 31 and abuts against the connecting cover 41, thereby connecting the shielding shell 5 to the housing ground. The shielding shell 5 provides a shielding effect, prevents leakage, and ensures safe use.

[0094] The surface and bottom surface of the upper plane sealing ring 22 and the bottom plane sealing ring 23 are provided with multiple ridges, each of which is distributed in a frame-shaped structure, which can improve the connection sealing between the upper plane sealing ring 22 and the floating part 31, and improve the connection sealing between the bottom plane sealing ring 23 and the fixed part 1; the floating part 31 and the fixed part 1 are sealed by the floating sealing ring 2, and the overall sealing is good.

[0095] like Figure 4 As shown, in an optional embodiment of the present invention, a first connecting groove 12 for accommodating a bottom plane sealing ring 23 is formed on the bottom surface of the fixing member 1. A plurality of first connecting nuts 13 are evenly arranged in the first connecting groove 12. The plurality of first connecting nuts 13 are inserted into the plurality of first connecting through holes 24 on the surface of the bottom plane sealing ring 23, and the plurality of first connecting nuts 13 correspond to the plurality of first positioning holes 711 on the surface of the housing cover 71.

[0096] The fixing member 1 is formed with a limit frame 11 on both sides, and the floating member 31 is formed with a limit rod 311 on both sides. The two limit rods 311 are respectively inserted into the two limit frames 11. The surfaces of the two limit rods 311 are formed with a limit baffle 3111. The two limit baffles 3111 correspond to the upper parts of the two limit frames 11 respectively.

[0097] A plurality of limiting blocks 14 are formed on the surface of the fixing member 1 , and the plurality of limiting blocks 14 correspond to the connecting cover plate 41 .

[0098] In this embodiment, when connecting the fixing member 1 to the casing cover 71 and the bottom plane sealing ring 23, the bottom plane sealing ring 23 is embedded in the first connecting groove 12, and the multiple first connecting nuts 13 are inserted into the multiple first connecting through holes 24. The fixing member 1 is placed on the surface of the casing cover 71, and the bottom surface of the bottom plane sealing ring 23 is connected to the surface of the casing cover 71. The multiple first connecting nuts 13 are coaxially corresponding to the multiple first positioning holes 711. Multiple bolts are used to penetrate the multiple first positioning holes 711 and are threadedly connected to the multiple first connecting nuts 13 to achieve a sealed connection between the fixing member 1, the bottom plane sealing ring 23 and the casing cover 71.

[0099] Multiple first connecting nuts 13 are evenly distributed along the periphery of the fixing member 1 to ensure that after the fixing member 1, the bottom flat sealing ring 23 and the housing cover 71 are sealed together, the fixing member 1 is evenly stressed and the bottom surface of the bottom flat sealing ring 23 is in full contact with the surface of the housing cover 71 to ensure sealing.

[0100] By limiting between two limiting rods 311 and two limiting frames 11, the position adjustment limit of the floating part 31 in the first direction is achieved, thereby avoiding damage to the rectangular sealing ring 21 due to excessive position adjustment; by limiting between two limiting baffles 3111 and two limiting frames 11, the position adjustment limit of the floating part 31 in the second direction is achieved, thereby avoiding damage to the rectangular sealing ring 21 due to excessive position adjustment; by limiting between multiple limiting blocks 14 and the connecting cover plate 41, the position adjustment limit of the floating part 31 in the third direction is achieved, thereby avoiding damage to the rectangular sealing ring 21 due to excessive position adjustment. While satisfying the multi-directional position adjustment of the floating part 31, the position adjustment of the floating part 31 is limited, thereby avoiding damage to the rectangular sealing ring 21 due to excessive position adjustment.
