The contact surface of the shell 110 and the top surface of the panel 200 is provided with an elastic sealing ring 115; the elastic sealing ring 115 is used to seal the gap between the housing 110 and the panel 200, and also can prevent the panel 200 from being damaged due to the rigid contact between the housing 110 and the panel 200. Specifically, the elastic sealing ring 115 may be disposed between the limiting portion 112 and the panel 200, or between the locking member 114 and the panel 200; the elastic sealing ring 115 is made of an elastic material such as elastic rubber or elastic plastic material.

Specifically, the insulating material may be wrapped outside the power supply lead 121, or may be laid at a position where the power supply lead 121 may contact the mounting cavity 111, as long as the insulating material can separate the power supply lead 121 from the mounting cavity 111, and the specific arrangement position and shape may be flexibly set by those skilled in the art according to actual conditions.

In the description of the present invention, it is to be understood that the orientation or positional relationship indicated by the orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, horizontal" and "top, bottom", etc. are usually based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplicity of description, and in the case of not making a reverse description, these orientation words do not indicate and imply that the device or element being referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore, should not be considered as limiting the scope of the present invention; the terms "inner and outer" refer to the inner and outer relative to the profile of the respective component itself.

Spatially relative terms, such as "above … …," "above … …," "above … …," "above," and the like, may be used herein for ease of description to describe one device or feature's spatial relationship to another device or feature as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if a device in the figures is turned over, devices described as "above" or "on" other devices or configurations would then be oriented "below" or "under" the other devices or configurations. Thus, the exemplary term "above … …" can include both an orientation of "above … …" and "below … …". The device may be otherwise variously oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

The technical principle of the present invention is described above in connection with specific embodiments. The description is made for the purpose of illustrating the principles of the utility model and should not be construed in any way as limiting the scope of the utility model. Based on the explanations herein, those skilled in the art will be able to conceive of other embodiments of the present invention without inventive effort, which would fall within the scope of the present invention.
