DETAILED DESCRIPTION
In this exemplary embodiment, the device is an electronic device such as a mobile telephone but any device employing an interface is applicable. Accordingly, any reference herein to the mobile telephone should also be considered to apply equally to other portable devices.
Referring to FIG. 1, an exemplary electronic device 100 includes a housing 10, a sealing assembly 60, an interface 30, and a circuit board 40. The interface 30 may be a power connector or a USB connector. The interface 30 is received in the sealing assembly 60 and electrically connected to the circuit board 40. The sealing assembly 60 and the circuit board 40 are both mounted on the housing 10. The sealing assembly 60 includes a main body 20 and a sealing element 50. The sealing assembly 60 is resilient and seals gaps occurring between the main body 20, the interface 30, the housing 10, and the circuit board 40.
Referring to FIG. 2, the housing 10 includes a bottom surface 11 and a peripheral wall 13 protruding from a peripheral edge thereof. The bottom surface 11 defines a mounting groove 111 near the peripheral wall 13 receiving the sealing assembly 60 and the interface 30 therein. The peripheral wall 13 defines an opening 131 communicating with the mounting groove 111. The opening 131 allows passage of peripheral device connectors therethrough, to link with the interface 30.
Referring to FIGS. 3 and 4, the main body 20 is hollow and defines a compartment 29 (see FIG. 8). The compartment 29, in this exemplary embodiment, is enclosed by a first end wall 21, a second end wall 23, a first board 25 and a second board 27. The first end wall 21 faces the opening 131, and the second end wall 23 is opposite to the first end wall 21. The first board 25 faces the bottom surface 11 of the housing 10, and the second board 27 is opposite to the first board 25. The first board 25 and the second board 27 respectively connect the first end wall 21 with the second end wall 23.
The first end wall 21 defines a hole 211 communicating with the compartment 29. The hole 211 is aligned with the opening 131 when the sealing assembly 60 is mounted to the housing 10. The second end wall 23 defines a first mounting hole 231 and a second mounting hole 233 therein, both of which communicate with the compartment 29. The interface 30 passes through the first mounting hole 231 and the second mounting hole 233, and into the compartment 29.
Referring to FIGS. 3-4, and 8, the sealing element 50 includes a first sealing portion 213, a second sealing portion 234, a third sealing portion 251 and a fourth sealing portion 271. The first sealing portion 213 is located between the first end wall 21 and the peripheral wall 13 to seal a first gap 71 occurring between the first end wall 21 and the peripheral wall 13. The second sealing portion 234 is located between the first mounting hole 231 and the interface 30 to seal a second gap 72 occurring between the first mounting hole 231 and the interface 30. The third sealing portion 251 is located between the first board 25 and the bottom surface 11 to seal a third gap 73 occurring between the first board 25 and the bottom surface 11. The fourth sealing portion 271 is located between the second board 27 and the circuit board 40 to seal a fourth gap 74 occurring between the second board 27 and the circuit board 40.
In this exemplary embodiment, the first sealing portion 213 surrounds the hole 211. The second sealing portion 234 is tubular, and received in and surrounds the first mounting hole 231. The third sealing portion 251 is U-shaped and extends from the edge of the first board 25 (See FIG. 3). The fourth sealing portion 271 is U-shaped and extends from the edge of the second board 27 (See FIG. 4).
The first sealing portion 213, the second sealing portion 234, the third sealing portion 251 and the fourth sealing portion 271 may be all made of resilient material, such as thermoplastic polyurethane (TPU). The main body 20 may be made of polycarbonate (PC). The interface 30 includes a retaining portion 31, a first resilient arm 32 and a second resilient arm 33. The retaining portion 31 is received in the first mounting hole 231 to mount the interface 30 to the main body 20. The retaining portion 31 and the first resilient arm 32 respectively pass through the first mounting hole 231 and the second mounting hole 233, and then into the compartment 29. The first resilient arm 32 provides electrical connection with the peripheral devices. The second resilient arm 33 provides electrical connection with the circuit board 40.
Referring to FIGS. 1, 2, 5 and 8, in assembly, the retaining portion 31 and the first resilient arm 32 respectively pass through the first mounting hole 231 and the second mounting hole 233 to mount the interface 30 to the sealing assembly 60. At this time, the second sealing portion 234 is elastically compressed and tightly resists the retaining portion 31, such that the first mounting hole 231 is sealed. The sealing assembly 60 is then received in the mounting groove 111 with the hole 211 aligned with the opening 131. At this time, the first sealing portion 213 is elastically compressed and tightly resists an inner surface of the opening 131 to seal the first gap 71 between the main body 20 and the housing 10, and the fourth sealing portion 271 elastically resists an inner surface of the mounting groove 111. The circuit board 40 is mounted to the housing 10 and electrically connects to the second resilient arm 33 to yield an assembled electronic device. At this time, the fourth sealing portion 271 is elastically compressed between the circuit board 40 and the main body 20 to seal the fourth gap 74 between the main body 20 and the circuit board 40.
In the exemplary embodiment, the first sealing portion 213, the second sealing portion 234, the third sealing portion 251 and the fourth sealing portion 271 are all made of resilient material. When the sealing assembly 60 is mounted to the housing 10, the first sealing portion 213, the second sealing portion 234, the third sealing portion 251 and the fourth sealing portion 271 are elastically compressed, respectively resisting the peripheral wall 13, the retaining portion 31, the bottom surface 11 and the circuit board 40, tightly. Thus the first gap 71, the second gap 72, the third gap 73 and the fourth gap 74 are sealed to prevent entry of contaminants into the interior of the electronic device.
It is to be understood, however, that even through numerous characteristics and advantages of the exemplary disclosure have been set forth in the foregoing description, together with details of the system and function of the disclosure, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
