The high-voltage pole penetrates through the mounting seat and is provided with an electric contact end and a wiring end. One end of the flexible electric connector is in floating electric connection with the wiring end of the high-voltage pole, and the other end of the flexible electric connector is in floating electric connection with the high-voltage plug. The low-voltage component comprises a low-voltage pole which is arranged on the mounting seat in a penetrating way and is arranged at intervals with the high-voltage pole.

The invention realizes floating connection from the plug-in position of the male end and the female end of the connector, and the problem of unstable connection is easy to exist after the connector is used for a period of time.

In addition, the existing floating connector mostly uses a spring as a floating structure, but the spring also has the problems of rusting after being used for a period of time and the like, and the service life of the floating connector is seriously influenced particularly in a humid environment.

Based on this, it is necessary to design a flexible connector and a floating connector to meet the use requirement.

Detailed Description

The following description is provided for illustrative purposes, and other advantages and features of the present invention will become apparent to those skilled in the art from the following detailed description.

Please refer to fig. 1-3. It should be understood that in the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate the position or positional relationship based on the position or positional relationship shown in the drawings, or the position or positional relationship that the product of the present invention is usually placed when in use, and are only for convenience of describing the present invention and simplifying the description, but do not indicate or imply that the device or element to which the term refers must have a specific position, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," "third," and the like are used solely to distinguish one from another and are not to be construed as indicating or implying relative importance. The terms "horizontal", "vertical", "overhang" and the like do not imply that the components are required to be absolutely horizontal or overhang, but may be slightly inclined. For example, "horizontal" merely means that the direction is more horizontal than "vertical" and does not mean that the structure must be perfectly horizontal, but may be slightly inclined.

In the description of the present invention, it should be further noted that, unless otherwise explicitly stated or limited, the terms "disposed," "mounted," "connected," and "connected" are to be construed broadly and may include, for example, a fixed connection, a detachable connection, an integral connection, a mechanical connection, an electrical connection, a direct connection, an indirect connection via an intermediate medium, and a connection between two elements.
