The invention will be further elucidated and described with reference to the following embodiments and drawings in which:

referring to fig. 1, 2 and 3, the floating connection structure includes a housing 10, the housing 10 is provided with a first interface 12, an electrical connection assembly is disposed in the housing 10, and the electrical connection assembly includes a first conductive end 20 disposed on the housing 10 and a conductive connection member 30 connected to the first conductive end 20. The first conductive end 20 is provided with a second interface 22 connected to the first interface 12, and the first inner wall 122 of the first interface 12 is an inclined surface that is opened outward toward the first interface 12.

When an external device needs to be inserted into the second connector 22 of the first conductive terminal 20 to achieve electrical connection, the first connector 12 needs to be inserted first, and if the external device has a position deviation with the second connector 22, the external device will collide with the first inner wall 122 of the first connector 12 first. Since the first inner wall 122 of the first connector 12 is a slope that is opened outward toward the first connector 12, the external device slides to the second connector 22 along the first inner wall 122 of the first connector 12 after collision and is inserted into the second connector 22 to realize electrical connection. The buffering and guiding by the first header 12 facilitates device insertion and makes the second header 22 less susceptible to damage by shock.

In this embodiment, the first inner wall 122 of the first connector 12 is a slope that opens outward to the first connector 12, so that the size of the outer opening of the first connector 12 is larger than that of the inner opening thereof, and therefore the first connector 12 can be used for inserting an external device that is misaligned with the second connector 22, which facilitates the insertion of the device. Specifically, the first inner wall 122 of the first connector 12 may be a completely inclined surface and then connected to the second connector 22 through the inclined surface, or an inclined surface near the outer opening and a flat surface near the inner opening and then connected to the second connector 22 through the flat surface, and the flat surface may be better connected to the second connector 22. And an external device can be electrically connected with the conductive connecting member 30 after being inserted into the second interface 22.

In this embodiment, at least one of the four first inner walls 122 of the first connector 12 is a slope that is opened outward toward the first connector 12. Specifically, when at least one of the upper and lower inner walls is inclined, the insertion of an external device that is deviated from the vertical position of the second connector 22 may be performed, and when at least one of the left and right inner walls is inclined, the insertion of an external device that is deviated from the horizontal position of the second connector 22 may be performed.

Specifically, after the external device is inserted, the external device sequentially passes through the first connector 12 and the second connector 22, and is inserted into the connector mounting groove 26 to be electrically connected to one end of the conductive connecting member 30. Therefore, by adding the guide 24, the inserted external device can be secondarily buffered and secondarily guided through the second interface 22, thereby further facilitating the insertion of the device and making one end of the conductive connection member 30 less susceptible to collision damage. Specifically, the second inner wall 222 of the second connector 22 and the first inner wall 122 of the first connector 12 are designed by the same inclined plane, and the second inner wall 222 of the second connector 22 may be an inclined plane, and then is connected to the connector mounting groove 26 by an inclined plane, or an inclined plane near the outer opening, and a plane near the inner opening, and then is connected to the connector mounting groove 26 by a plane, and the plane may be better connected to the connector mounting groove 26.
