## Background
CROSS-REFERENCE TO RELATED APPLICATION(S)
This application claims the benefit under 35 U.S.C. §119(a) of a Korean patent application filed on Sep. 22, 2014 in the Korean Intellectual Property Office and assigned Serial number 10-2014-0126116, the entire disclosure of which is hereby incorporated by reference.
TECHNICAL FIELD
The present disclosure relates to a waterproof key apparatus. More particularly, the present disclosure relates to a waterproof key apparatus that may implement waterproofing between a main case and a printed circuit board (PCB) by using a sealing rubber, may make a set light, slim, short, and small, and may remove a reason for a degradation in the feeling of clicking a key, in a smart device having physical keys on the surface thereof.
BACKGROUND
In general, a smart device has a physical key structure on the front surface thereof, and there are clearances for the operation of physical keys in the set.
However, liquid, such as water, infiltrates into the set through such clearances to cause short circuits and malfunctions in circuit components.
In order to prevent the problems, a waterproof structure is integrally applied to a key itself, or a waterproof membrane structure is applied between a key and a dome in a waterproof method for a physical key in the related art.
However, the waterproof structure integrally applied to the key has a complex structure and makes it difficult to decrease the size of the set.
For instance, in the case of a waterproof key integrated type using a waterproof tape, a water proof tape around a key prevents moisture from being introduced into a key hole, but occupies a double space together with a waterproof tape for a window.
Though unlikely, in the case of a waterproof key integrated type using a rubber sealing, a rubber waterproof structure using a rubber flange surrounds a key, and a so-called skirt structure is accordingly required between keys to improve the click feeling and occupies a large amount of space.
Also, a waterproof membrane structure applied between a key and a dome causes degradation in the feeling of clicking a key.
Namely, in the case of a separate waterproof rubber assembly type, a waterproof rubber having no hole is interposed between a key actuator and a dome to prevent the infiltration of moisture, but the feeling of click is necessarily deteriorated by the waterproof rubber between the key and the dome.
Further, an “L” shaped liquid crystal display (LCD) bracket structure made of a metal material has to be necessarily configured to implement a metal device antenna (MDA) that uses an LCD bracket on the front surface thereof, a printed circuit board (PCB), a universal serial bus (USB), and the like, as an antenna radiator.
The above information is presented as background information only to assist with an understanding of the present disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the present disclosure.
SUMMARY
Aspects of the present disclosure are to address at least the above-mentioned problems and/or disadvantages and to provide at least the advantages described below. Accordingly, an aspect of the present disclosure is to provide a waterproof key apparatus in which a waterproof structure is separated from a key by implementing waterproofing using a sealing rubber between a main case and a printed circuit board (PCB), thereby making a set light, slim, short, and small, and a waterproof membrane structure between an actuator and a dome of a key is removed, thereby enhancing the feeling of clicking a key.
In accordance with an aspect of the present disclosure, a waterproof key apparatus of an electronic device is provided. The waterproof key apparatus includes a main case, a key module attached to a side of the main case and comprises a key actuator, a window to which the key module is coupled, a universal serial bus (USB) coupling module and a PCB attached to an opposite side of the main case, with a dome sheet therebetween, a key bracket and an antenna cap coupled to the lower portion of the PCB, and a sealing part attached between the main case and the PCB to seal the rear surface of the PCB.
In accordance with another aspect of the present disclosure, a waterproof key apparatus of an electronic device is provided. The waterproof key apparatus includes first and second main cases, a key module attached to the second main case and comprises a key actuator, a PCB mounted on the lower portion of the first main case, with a dome sheet therebetween, and a sealing part attached between the first main case and the PCB to seal the rear surface of the PCB.

FIG. 3 is a perspective view of a sealing rubber of FIG. 1 according to an embodiment of the present disclosure.
FIG. 4 is a sectional view taken along line A-A of FIG. 3 according to an embodiment of the present disclosure.
Referring to FIGS. 3 and 4, each of the sealing rubbers 300 has an annular shape surrounding the periphery of a hole of a key module 220 and may include an opening 302 and a waterproof EMBO 304 radially protruding from the periphery of the opening 302.
FIG. 5 is a sectional view of major parts, coupled to one another, for explaining a waterproof embodiment using sealing rubbers of FIG. 1 according to an embodiment of the present disclosure.
Referring to FIG. 5, the key module 220 including a key actuator 202 and the window 240 to which the key module 220 is coupled are attached to the upper portion of the main case 100 by an adhesive tape 102, and the sealing rubber 300 is interposed between the bottom of the main case 100 and the PCB 340. The waterproof EMBO 304 of the sealing rubber 300 radially overlaps the PCB 340 to prevent the infiltration of moisture into circuit components on the rear surface of the PCB 340, thereby realizing waterproofing.
The PCB 340 and the key bracket 360 on the rear surface of the PCB are fastened to each other through one or more screws (not illustrated), and the fastening force therebetween has to be able to maintain the waterproof sealing formed by the overlap between the waterproof EMBO 304 and the PCB 340.
The USB coupling module 320 to which a USB is coupled is formed on a side of the key bracket 360 on the rear surface of the PCB 340, and a dome sheet 310 may be interposed between the plurality of sealing rubbers 300 and the PCB 340.
FIGS. 6A and 6B are views illustrating states in which a sealing rubber of FIG. 1 is attached, according to shapes thereof according to an embodiment of the present disclosure.
Referring to FIGS. 6A and 6B, the dome sheet 310 may be of a surface mounted diode (SMD) dome type or a dome sheet type.

A speaker 410 may be mounted on the rear surface of the PCB 340, and then a PCB rear-side assembly 400 may be assembled.
At this time, a sealed room is formed between the rear surface of the PCB 340 and the PCB rear-side assembly 400. Such a room is sealed by the sealing rubber 300 and thus may be used as an enclosure like the resonance box of the speaker 410 without a separate additional structure.
FIGS. 8 and 9 illustrate a waterproof key apparatus which may implement a metal device antenna (MDA) according to an embodiment of the present disclosure.
Referring to FIGS. 8 and 9, a rear bracket 500 is insert-molded to the main case 100 of a set having a front key structure, and a liquid crystal display (LCD) bracket 520 and the rear bracket 500 are electrically connected to each other, whereby a MDA may be implemented with the LCD bracket 520 having no separate additional metal structure for electrical conduction.
FIGS. 10A and 10B illustrate a waterproof key apparatus which may realize a waterproof structure for one button key and left and right touch keys according to an embodiment of the present disclosure.
Referring to FIG. 10A, in cases where the waterproof key apparatus, according to the embodiment of the present disclosure described above, in which the sealing rubbers 300 are attached between the bottom of the main case 100 and the PCB 340, is applied to a set having a front key structure, the waterproof EMBOs 304 of the sealing rubbers 300 may overlap the PCB 340 while spreading radially.
In this case, the dome sheet 310 is positioned in the center of the PCB 340 such that a general home key is coupled as a button key, and flexible PCBs (FPCBs) 342 for a touch key may be integrally formed with the PCB 340, on left and right sides of the dome sheet 310.
Referring to FIG. 10B, the FPCBs 342 for a touch key pass through the injection holes 108 of the main case 100, protrude upward from the main case 100, and then are bent, and a general shape of a home key 350 is assembled as a button key on the upper portion of the dome sheet 310, thereby realizing a water proof structure for the central button key and the left and right touch keys.
FIG. 11 illustrates a waterproof key apparatus which may realize a waterproof structure for one button key to which a sensor is attached and left and right touch keys according to an embodiment of the present disclosure.
Referring to FIG. 11, the sensor-attached button key is coupled to the center of the PCB 340. Accordingly, the following description will be focused on a difference therebetween.
A sensor-attached button key 600 includes a button 610, a horizontal extending piece 620 that horizontally extends from a side of the button 610, a bent piece 640 that is vertically bent downward from the horizontal extending piece 620, and a sensor 650 attached to the bent piece 640.

The side key module 800 includes a key actuator 802 and is coupled to the first main case 110.
The sealing rubber 300 may be attached between the lower portion of the second main case 120 and the PCB 340 having the dome sheet 310.
Likewise to the first embodiment described above, the waterproof EMBO (not illustrated) of the sealing rubber 300 overlaps the second main case 120 while spreading radially to prevent the infiltration of moisture into circuit components on the rear surface of the PCB 340, thereby realizing waterproofing. The key bracket 360 is fastened to the rear surface of the PCB 340 through a plurality of screws, and the fastening force therebetween has to be able to maintain the waterproof sealing formed by the overlap between the waterproof EMBO and the second main case 120.
After the assembly of the components as described above, final waterproofing may be completed by a waterproof cap (not illustrated).
