Example:

As shown in FIG. 1 , a floating connector proposed in this application includes a plug 1 and a socket assembly 2 .

As shown in FIG. 2 , it is a cross-sectional view of the socket assembly in the present application. It can be seen that the socket assembly 2 includes a socket 22 and a positioning plate 21. The positioning plate 21 has an opening in the center, and the opening extends inward to form a cavity for accommodating the socket 22, and the socket 22 is arranged in the cavity.

It also includes a first annular limiting member 4, and the outer wall of the first annular limiting member 4 is provided with an external thread that fits with the internal thread at the open end of the large inner diameter section. The first annular limiting member 4 is screwed into the large inner diameter section and forms an annular groove 6 with the cavity.

A second annular limiting member 5 is sleeved on the outer wall of the socket 22 , and an annular convex ridge 7 is provided on the outer wall of the second annular limiting member 5 , and the annular convex ridge 7 is movably arranged in the annular groove 6 .

The limiting mechanism formed by the annular convex ridge 7 and the annular groove 6 can limit the movement of the socket 22 along the axial or radial direction of the cavity.

Innovation:

A flexible connector 3 is sealed and connected between the plug end of the socket 22 and the open end of the positioning plate 21 .

Specifically, the flexible connecting piece is made of elastic material and has a stepped cylindrical shape, the upper port diameter of the flexible connecting piece 3 is smaller than the lower port diameter, and the upper end of the flexible connecting piece 3 has a cylindrical first connecting portion 31 extending inwardly. The lower end of the flexible connecting member 3 has a flat annular second connecting portion 32 that expands outward, and the axis of the first connecting portion 31 and the axis of the second connecting portion 32 are coincident.

The first connection part 31 and the outer wall of the plug end of the socket 22 are sealed and connected by a vulcanization process, and the second connection part 32 and the front wall of the opening end of the positioning plate 21 are sealed and connected by a vulcanization process to achieve waterproofing.

The flexible connector 3 can reset the socket 22 after being subjected to an axial or radial force, and is used in conjunction with a limiting mechanism to prevent the flexible connector 3 from excessive elastic deformation, thereby affecting its service life and improving its service life.

Reset principle:

1. The stepped cylindrical structure of the flexible connector 3, in accordance with its own material properties, can automatically reset the socket 22 fixed to it after being subjected to an axial force.

2. After the socket 22 and the flexible connector 3 are fixedly connected, the socket 22 is suspended in the cavity, and the axis of the socket 22 coincides with the axis of the first connection part 31 and the axis of the second connection part 32 . In this way, combined with the material properties of the flexible connector 3 itself, the socket 22 automatically resets after being subjected to a radial force.

Technical comparison:

Compared with floating connectors using springs, there is no rust problem and the production and assembly costs are also lower.

Compared with the floating connector using the bellows structure, the traditional bellows structure itself determines that its fatigue resistance and reliability are insufficient, and it is prone to permanent deformation after use, which requires manual correction, otherwise the set of connectors will fail and be scrapped. The radial and axial swing/float range is not easy to control. However, the flexible connector 3 in the present application has the function of resetting, and is used in combination with a limiting mechanism capable of controlling the amount of elastic deformation, thereby prolonging the service life.

Therefore, the present invention has the following advantages:

The floating connector proposed in the present application has a simple structure and low production cost, uses a flexible connector to cooperate with a limiting mechanism, has stable connection and has waterproof performance, and is suitable for promotion.
