[0030] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] See also Figure 1 As shown, the utility model discloses a floating electrical connector 100, which is installed on a device housing 200. In this embodiment, the floating electrical connector 100 is preferably used on a pack battery, and the device housing 200 is a battery shell. The floating electrical connector 100 is installed below the battery shell. By setting the floating electrical connector 100, the floating electrical connector 100 can be accurately connected to an external plug while allowing position deviation during pack battery assembly. It can also be used to release the torsion of the pack battery caused by the non-vertical wall when it is hung on the wall, thereby minimizing internal stress and extending the service life. It should be noted that the application scenarios of the floating electrical connector 100 are various and not limited to pack batteries.

[0032] like Figure 2 and Figure 4 As shown, the floatable electrical connector 100 includes a connector body 1, a first elastic member 2, a second elastic member 3, and a fastener 4. The connector body 1 is assembled on the device housing 200, with the first elastic member 2 and the second elastic member 3 assembled between the connector body 1 and the device housing 200. The fastener 4 sequentially passes through the connector body 1, the second elastic member 3, and the device housing 200 to mount the connector body 1 to the device housing 200. The connector body 1 is capable of floating relative to the fastener 4 and the device housing 200 under the elastic action of the first elastic member 2 and the second elastic member 3. The floatable electrical connector 100 of the present invention not only achieves both floating and waterproof properties, but also has a simple structure and is easy to install.

[0033] Specifically, the connector body 1 is spaced apart from the device housing 200. In this embodiment, a 1.2 mm gap is preferably left between the connector body 1 and the device housing 200 to ensure that the connector body 1 can float relative to the device housing 200. Of course, in other optional embodiments, the gap between the connector body 1 and the device housing 200 can be adjusted according to floating requirements, and this is not limited to this.

[0034] The connector body 1 partially extends into the device housing 200. Specifically, the device housing 200 is provided with a mounting opening 202, through which the connector body 1 extends. A protruding stopper (unnumbered) is provided on the inner wall of the mounting opening 202. The connector body 1 is provided with a receiving groove 10 adapted to the stopper. The stopper is received and movable within the receiving groove 10, providing initial positioning of the connector body 1 through the stopper and the receiving groove 10.

[0035] The connector body 1 includes a connection terminal 12. One end of the connection terminal 12 is located within the device housing 200 and connected to the cable 300, and the other end is used to connect to an external plug. In this embodiment, the outer periphery of the connector body 1 is provided with a protruding mounting portion 11. The mounting portion 11 is located outside the device housing 200. The fastener 4 passes through the mounting portion 11 to connect to the device housing 200.

[0036] Combine Figure 5-Figure 8 As shown, one side of the first elastic member 2 is fixedly engaged with the connector body 1, and the other side is in close contact with the device housing 200. Specifically, the first elastic member 2 is arranged in a ring shape and is arranged on the connector body 1. The first elastic member 2 is preferably assembled on the side of the mounting portion 11 facing the device housing 200. The first elastic member 2 not only enables the connector body 1 to float relative to the fastener 4 and the device housing 200, but also plays a waterproof role as a sealing gasket. In this embodiment, the first elastic member 2 is preferably made of rubber and has a deformation space.

[0037] The first elastic member 2 has a first protrusion 21 projecting toward the mounting portion 11 and a second protrusion 22 projecting toward the device housing 200. The mounting portion 11 is provided with a corresponding first receiving groove 110 for accommodating the first protrusion 21, and the second protrusion 22 is in close contact with the outer surface of the device housing 200. The first protrusion 21 is annular, and the first elastic member 2 is further provided with a positioning boss 23 located outside the first protrusion 21. The mounting portion 11 is provided with a corresponding positioning groove 111 into which the positioning boss 23 extends. Two positioning bosses 23 are provided, located at opposite ends of the first elastic member 2. The positioning bosses 23 extend into the positioning grooves 111, restricting the connector body 1 from rotating in a horizontal plane. Specifically, using three-dimensional coordinates, with the x-axis as the horizontal axis, the y-axis as the vertical axis, and the z-axis as the vertical axis, the connector body 1 can rotate slightly toward the plane formed by the x-axis and the z-axis, as well as the plane formed by the y-axis and the z-axis. The rotation angle is preferably 2-3°, that is, when the floatable electrical connector 100 is connected to the external plug, there is a position deviation of 2-3°.

[0038] The second protrusion 22 is annular. The second protrusion 22 includes a movable rib 221 extending toward the device housing 200 and a contact head 222 located at one end of the movable rib 221 near the device housing 200. The contact head 222 maintains close contact with the device housing 200, and the movable rib 221 spaces the connector body 1 and the device housing 200, i.e., the movable rib 221 is located within the gap between the connector body 1 and the device housing 200. In this embodiment, when the connector body 1 floats, the contact head 222 always abuts against the device housing 200 and remains in position. The movable rib 221 deforms to achieve floating position of the connector body 1. It can be seen that by adjusting the size of the gap between the connector body 1 and the device housing 200 and the extension length of the movable rib 221, the steering angle of the connector body 1 can be adjusted, thereby achieving a larger position deviation.

[0039] One end of the second elastic member 3 abuts the connector body 1, and the other end extends toward the device housing 200. In this embodiment, the mounting portion 11 of the connector body 1 is provided with a first limiting hole 112 for the fastener 4 to pass through, and the device housing 200 is correspondingly provided with a second limiting hole 201 for the fastener 4 to pass through. The fastener 4 fits into the second limiting hole 201, securing the fastener 4 to the device housing 200. The inner diameter of the first limiting hole 112 is larger than the inner diameter of the second limiting hole 201, allowing the connector body 1 to float along the first limiting hole 112.

[0040] The first limiting hole 112 and the second limiting hole 201 are coaxially arranged, and the second elastic member 3 is at least partially accommodated in the first limiting hole 112 and abuts against the mounting portion 11. Specifically, a step portion 113 is provided at the end of the first limiting hole 112 away from the device housing 200, so that the inner diameter of the end of the first limiting hole 112 away from the device housing 200 is smaller than the inner diameter of the end of the first limiting hole 112 closer to the device housing 200. A through hole 114 is formed through the step portion 113, and the through hole 114 is connected to the first limiting hole 112.

[0041] Combine Figure 9 As shown, the second elastic member 3 is preferably a spring. A limiting post 31 is provided at the end of the second elastic member 3 away from the device housing 200. The limiting post 31 is inserted into the through-hole 114 to connect the second elastic member 3 to the mounting portion 11. In this embodiment, the second elastic member 3 is tapered, with its ends respectively adapted to the diameters of the first limiting hole 112 and the second limiting hole 201. That is, the inner diameter of the second elastic member 3 gradually decreases from the first limiting hole 112 toward the second limiting hole 201.

[0042] The second elastic member 3 is also coaxially arranged with the first limiting hole 112 and the second limiting hole 201 , so that the fastener 4 can pass through the first limiting hole 112 and the second limiting hole 201 in a centered and rapid manner.

[0043] In this embodiment, the first elastic member 2 is further provided with an escape hole 24, through which the second elastic member 3 extends toward the device housing 200. Of course, in other optional embodiments, the shape or size of the first elastic member 2 can be changed so that the second elastic member 3 can extend toward the device housing 200 without hindrance.

[0044] like Figure 10 As shown, the outer wall of the fastener 4 is provided with a protruding engaging portion 41. After passing through the second elastic member 3 from the first limiting hole 112, the engaging portion 41 engages with the end of the second elastic member 3 near the second limiting hole 201. In this embodiment, the floatable electrical connector 100 is mounted below the device housing 200 and is subject to its own gravity. The engaging portion 41 engages with the end of the second elastic member 3 near the second limiting hole 201, further preventing the fastener 4 from falling off and improving the connection strength between the connector body 1 and the device housing 200.

[0045] In summary, the floatable electrical connector 100 of the present invention utilizes a first elastic member 2 and a second elastic member 3 to be assembled between the connector body 1 and the device housing 200. A fastener 4 is then inserted sequentially through the connector body 1, the second elastic member 3, and the device housing 200, thereby securing the connector body 1 to the device housing 200. This allows the connector body 1 to float relative to the fastener 4 and the device housing 200 under the elastic action of the first elastic member 2 and the second elastic member 3. Furthermore, by configuring the first elastic member 2 so that one side is fixedly engaged with the connector body 1 and the other side is in close contact with the device housing 200, the waterproof performance between the connector body 1 and the device housing 200 is enhanced. Compared to the prior art, the floatable electrical connector 100 of the present invention achieves both floating and waterproof properties, has a simple structure, and is easy to install.

[0046] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention.
