Detailed Description

In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, as those skilled in the art will be able to make similar modifications without departing from the spirit and scope of the present invention.

It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1-3, a waterproof tuner comprises a shell assembly 1, a shielding shell 2, a circuit board 3 and a connector 4, the shell assembly 1 comprises a sealing cover 11 and a shell 12, the sealing cover 11 is detachably connected with the shell 12, the shielding shell 2 is installed in a space formed by the sealing cover 11 and the shell 12, the circuit board 3 is installed in the shielding shell 2, the shell 12 is far away from the sealing cover 11, one end of the sealing cover is provided with a through hole 121 and a flow deflector 122, the flow deflector 122 is arranged on the shell 12 in a surrounding mode, the through hole 121 is provided with a baffle 123 at the joint of the flow deflector 122, and the connector 4 is penetrated through the through hole 121 and the circuit board 3 is electrically connected. Specifically, in this embodiment, the housing assembly 1 is installed as the outermost protective housing protection at the shielding shell 2 inside the housing assembly 1, and the shielding shell 2 is prevented from being directly exposed to the sun and rain, so that the circuit board 3 inside the shielding shell 2 is affected with damp.
