Automatic centering structure for floating fixing seat of connector

Abstract

An automatic centering structure for a floating fixed seat of a connector includes a fixed seat, a connector, and an annular spring. The fixed seat has an open side and a closed side, and an accommodating space is formed therein. The closed side has a through hole. The connector is movably disposed in the accommodating space and includes a first end and a second end opposite to each other. The first end extends through the through hole to the outside of the fixed seat. The second end extends toward the open side. The annular spring is disposed between the fixed seat and the connector and includes a fixed ring and several extension arms. The extension arms extend outward from the fixed ring and abut against the inner side of the fixed seat. When the connector is subjected to an external force and undergoes radial displacement, it drives the fixed ring and causes the extension arms to deform. When the external force disappears, the radial rebound force is released to return the connector to the center position.

Claims

1. An automatic centering structure for a floating fixing seat of a connector, comprising: a fixing seat having an open side and a closed side, the fixing seat forming an accommodating space and having a through hole on the closed side; a connector movably disposed in the accommodating space, wherein the connector includes a first end and a second end, the first end extending through the through hole to the outside of the fixing seat, and the second end extending toward the open side; and an annular spring piece disposed between the fixing seat and the connector, and comprising: a fixing ring located in the accommodating space and sleeved on the connector; and a plurality of extending arms distributed on one outer surface of the fixing ring to surround the fixing ring, and extending outward from the fixing ring and abutting against one inner side surface of the fixing seat; When the connector is subjected to an external force and undergoes a radial displacement relative to the fixed base, the connector drives the fixed ring and causes at least one of the extension arms to deform. When the external force disappears, the at least one of the extension arms releases a radial rebound force to push the fixed ring to return the connector to a central position.

2. The automatic centering structure of the floating fixing seat of the connector as described in claim 1 further comprises: a support pad located in the receiving space, and comprising: a pad neck extending outward through the through hole; a radial flange portion engaging one end of the pad neck and abutting the closed side; and a sleeve portion extending axially from the radial flange portion and passing through the fixing ring, wherein the support pad is sleeved on the first end through the sleeve portion; and an elastic member sleeved on the first end, and one end of the elastic member being received in the sleeve portion.

3. The automatic centering structure of the floating fixing seat of the connector as described in claim 2 further includes at least one retaining ring disposed on the sleeve portion and adjacent to the annular spring piece for axial alignment of the annular spring piece.

4. The automatic centering structure for the floating anchor as described in claim 1, wherein the number of the extension arms is at least three.

5. The automatic centering structure of the floating fixing seat of the connector as described in claim 1, wherein the fixing ring and the extension arms are integrally formed.

6. The automatic centering structure of the floating fixing seat of the connector as described in claim 1, wherein the extension arms are fixed to the fixing ring by means of plugging, welding or riveting.

7. The automatic centering structure of the floating fixing seat of the connector as described in claim 1, wherein each of the extension arms includes a fixed end and a free end, the fixed end being fixed to the fixing ring such that the extension arm is a cantilever structure and extends from the fixing ring in a circumferential direction, and the free end abutting against the inner surface in an elastic preload manner.
