Description

Technical Field

[0001] This invention relates to the field of connectors, and more specifically to a floating connector. Background Technology

[0002] Connectors generally refer to electrical connectors, whose function is to bridge gaps in a circuit or between isolated circuits, allowing current to flow and enabling the circuit to perform its intended function. Nowadays, connectors also connect optical signals, using glass and plastic instead of wires in ordinary circuits to transmit optical signals.

[0003] In existing technologies, the distance between the mounting plate on the fixed end and the PCB board on the floating end is fixed when installing a connector. If the distance between the mounting plate and the PCB board is not adjusted properly or if there is a deviation or displacement during installation, it will result in the inability to install the connector, and it is also inconvenient to adjust.

[0004] Therefore, it is necessary to provide a new technical solution. Summary of the Invention

[0008] The connecting terminal is provided with a stop device, and the connecting terminal is fixed by the stop device and the fixed end.

[0009] The first end of the floating terminal is sleeved on one end of the connecting terminal. The floating terminal is movable back and forth relative to the connecting terminal. The diameter of the second end of the floating terminal is smaller than the diameter of the first end. A protruding step is formed at the connection between the first end and the second end of the floating terminal.

[0010] The floating fixed back cover has a connecting hole in the middle. After the second end of the floating terminal passes through the connecting hole, the floating terminal is engaged with the floating fixed back cover by a step. The floating fixed back cover moves as the floating terminal moves.

[0011] A limiting device is provided at the end of the fixed end, and the floating fixed back cover is engaged within the limiting device, which limits the range of movement of the floating fixed back cover.

[0012] The PCB board is soldered to the position where the second end of the floating terminal extends out of the floating fixed back cover.

The stopping portion extends outward in a trumpet shape from the middle of the connecting portion. The outermost end of the stopping portion has a length in the axial direction of the connecting terminal that does not exceed the length of the connecting portion. The opening of the stopping portion faces the direction of the floating fixed back cover. The diameter of the outermost part of the stopping portion is larger than the diameter of the inner wall at the corresponding position of the fixed end. The stopping portion has a certain degree of elasticity.

[0016] A stop groove is provided on the inner wall of the fixed end corresponding to the position of the stop part. The shape of the stop groove is an inwardly concave triangle or arc.

The fixing block is a protrusion integrally formed with the floating terminal, and the axial length of the connecting part is less than the distance between the two rings of fixing blocks.

[0018] Furthermore, the main body of the connecting part is an annular shape with a notch, and one or more rectangular through holes are provided in the middle of the connecting part, and the stop part extends obliquely outward from one side edge of the rectangular through hole.

[0019] Furthermore, a clamping device is provided inside the first end of the floating terminal, and the floating terminal clamps the end of the connecting terminal through the clamping device.

[0020] The clamping device includes fixed rings at both ends and elastic plates connecting the two fixed rings. Each fixed ring has a notch. The elastic plates are evenly spaced between the fixed rings, with a concave inward curve in the middle. The diameter of the narrowest point of the elastic plate is smaller than the outer wall diameter of the corresponding part of the connecting terminal.

[0021] The floating terminal has a groove on the inner wall of the clamping device, and the clamping device is engaged in the groove.
