In an embodiment of the present invention, a waterproof sealing structure 100 for a jack is provided, which is applied to an electronic device, and is used for performing waterproof sealing treatment on the jack of the electronic device, so as to improve the waterproof performance of the electronic device. The jack includes, but is not limited to, openings such as earphones, USB, side keys, speakers, and the like.

As shown in fig. 1 to 4, the waterproof sealing structure 100 for a jack includes a first housing 10, a second housing 20, a main board 30, and a foam ring 40. In the present embodiment, the first casing 10 is a front casing, the second casing 20 is a rear casing, and the main board 30 is fixed in a space defined by the first casing 10 and the second casing 20. Specifically, the first housing 10 is provided with a positioning column 11, and the main board 30 is provided with a positioning hole (not shown) matching with the positioning column 11. The positioning holes are used for being matched with the positioning columns 11 so as to fix the main board 30 at a preset position of the first shell 10, and the assembling precision of the main board 30 is improved.

Specifically, the first housing 10 is provided with a slot 12 opened to the outside. The slot 12 is used for fixing an external interface, for example, the slot 12 is used for fixing a USB interface or a headset interface. In the present embodiment, the slot 12 is a USB port and has a rectangular parallelepiped shape. A sealing groove 13 is formed around the slot 12. The sealing groove 13 may be communicated with the slot 12, or may be disposed at intervals. Wherein, the sealing groove 13 is strip-shaped, and the shape is consistent with the corresponding position of the foam ring 40.

As shown in fig. 1 and 5, the foam ring 40 is a flexible and bendable planar irregular structure, which is rectangular in the present embodiment, and includes a first portion 41 and a second portion 42 folded at 180 °. That is, the first portion 41 and the second portion 42 are arranged in parallel at an interval from each other. The first portion 41 is pressed in the sealing groove 13 by the main board 30, and the second housing 20 is fastened to the first housing 10, so that the second portion 42 is pressed at a predetermined position of the main board 30, and the periphery of the slot 12 is sealed. Specifically, during assembly, the first portion 41 is fixed to the sealing groove 13 by a back adhesive, and then the main board 30 is fixed to the first housing 10, and the second portion 42 extends out of the sealing groove 13 and the slot 12. Then, the second portion 42 is turned over by 180 ° toward the inside to make the second portion 42 adhere to the preset position of the main board 30, and finally, the second housing 20 is fixed on the first housing 10, so that the second portion 42 is pressed on the main board 30. At this time, as shown in fig. 1, the foam ring 40 is in a groove shape surrounding the slot 12 with respect to a vertical projection on the first housing 10, that is, the first portion 41 and the second portion 42 are spaced up and down in the projection direction. The joint between the first portion 41 and the second portion 42 is attached to the side surface of the main board 30, thereby sealing the gap in the vertical direction (i.e., the Y-axis direction) of the socket 12.

The foam ring 40 is designed into an integrated structural form, so that the material cost is saved, the assembly procedures are reduced, the structure is simple, the operation is easy, and the sealing performance is better. The traditional waterproof structure needs to attach sealing foam on the upper surface and the lower surface of the USB hole respectively, and the assembly of the mainboard comprises three processes. The utility model reduces the three processes of assembling the main board into two processes of adhering sealing foam and installing the main board, thereby reducing the processes and lowering the production cost.

Further, the second housing 20 is provided with a foam sealing surface 21. The shape of the foam sealing surface 21 is consistent with that of the second part 42, so that the second part 42 is uniformly pressed on the main board 30 by the second shell 20, pressure balance at each position is ensured, and the situation of local poor sealing is avoided.

Optionally, as shown in fig. 4, the jack waterproof sealing structure 100 further includes a horn sealing ring 43 and a horn 50 electrically connected to the main board 30. The speaker 50 is generally disposed at a middle position of the first casing 10 or the second casing 20, and is spaced apart from the slot 12. Specifically, the first housing 10 is provided with a first horn sealing surface 14 conforming to the shape of the horn seal 43, and the second housing 20 is provided with a second horn sealing surface 22 conforming to the shape of the first horn sealing surface 14. The first horn sealing surface 14 and the second horn sealing surface 22 press the horn sealing ring 43 together to seal the horn 50, so as to prevent external water vapor from entering the main board 30 through the horn hole to cause corrosion. Wherein, in order to practice thrift material cost, reduce the equipment process, thereby horn seal 43 and bubble cotton circle 40 pass through connecting portion 44 to be connected and form the integrated design. In this embodiment, the horn seal 43 is located on the same plane as the bubble ring 40.

The present invention also provides an electronic device including the waterproof and sealing structure 100 for a jack according to any one of the above embodiments.

In summary, in the waterproof sealing structure 100 for a jack provided by the present invention, the sealing groove 13 is formed around the slot 12, and the main board 30 is fixed on the first housing 10, so that the main board 30 fixes the first portion 41 of the foam ring 40 in the sealing groove 13, and then the second portion 42 of the foam ring 40 is pressed on the predetermined position of the main board 30 through the second housing 20. Because first part 41 and second part 42 are 180 fifty percent discount settings, consequently, also there is the cotton existence of bubble between first part 41 and second part 42, have promoted water-proof effects, simultaneously through the limiting displacement of seal groove 13, also reduced the equipment degree of difficulty.

The utility model is not limited solely to that described in the specification and embodiments, and additional advantages and modifications will readily occur to those skilled in the art, so that the utility model is not limited to the specific details, representative apparatus, and illustrative examples shown and described herein, without departing from the spirit and scope of the general concept as defined by the appended claims and their equivalents.
