This application claims priority to Chinese Patent Application No. 201310411497.1 filed on Sep. 11, 2013, the contents of which are incorporated by reference herein.
The disclosure generally relates to a jack assembly and a portable electronic device with the jack assembly.
Portable electronic device, such as a mobile phone or a personal digital assistant (PDA), commonly has a jack for receiving an electronic element, for example, an earphone plug. When the electronic element is used, an unexpected pull on a line of the electronic element may pull the electronic element out of the jack.
Implementations of the present technology will now be described, by way of example only, with reference to the attached figures.
It will be appreciated that for simplicity and clarity of illustration, where appropriate, reference numerals have been repeated among the different figures to indicate corresponding or analogous elements. In addition, numerous specific details are set forth in order to provide a thorough understanding of the embodiments described herein. However, it will be understood by those of ordinary skill in the art that the embodiments described herein can be practiced without these specific details. In other instances, methods, procedures and components have not been described in detail so as not to obscure the related relevant feature being described. Also, the description is not to be considered as limiting the scope of the embodiments described herein. The drawings are not necessarily to scale and the proportions of certain parts have been exaggerated to better illustrate details and features of the present disclosure.
Several definitions that apply throughout this disclosure will now be presented.
The term “substantially” is defined to be essentially conforming to the particular dimension, shape or other word that substantially modifies, such that the component need not be exact. For example, substantially cylindrical means that the object resembles a cylinder, but can have one or more deviations from a true cylinder. The term “comprising” when utilized, means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in the so-described combination, group, series and the like.
The housing 10 includes a bottom surface 101 and a peripheral wall 102. The peripheral wall 102 extends substantially perpendicularly from a periphery of the bottom surface 101. An assembling hole 11 is defined in an inner surface of the peripheral wall 102 and an outside surface of the peripheral wall 102. The bottom surface 101 and the peripheral wall 102 cooperatively form a mounting space 13. The mounting space 13 communicates with the assembling hole 11.
As illustrated, the housing 10 further includes at least one post 15. In this embodiment, there are two posts 15. The two posts 15 are positioned in the bottom surface 101 and each post 15 defines an axis hole 151.
The circuit board 20 can be received in the mounting space 13. The circuit board 20 includes at least one mounting hole 21 corresponding to the at least one post 15 and at least one mounting element 23. In this embodiment, there are two mounting holes 21 and two mounting elements 23. The mounting elements 23 can be screws. The circuit board 20 is received in the mounting space 13 through the two mounting elements 23 extending through the corresponding mounting holes 21 and the axis holes 151, and is supported by the posts 15. In other embodiments, the circuit board 20 can be received in the mounting space 13 through other means.
The jack assembly 40 includes a jack element 41, an elastic element 43, a sealing element 45, and a connector 47. The jack element 41 is positioned in the inner surface of the peripheral wall 102 and defines a jack 411. The jack 411 is aligned with the assembling hole 11 and communicates with the assembling hole 11 and the mounting space 13.
The elastic element 43 is substantially a closed ring and is assembled in a side of the jack element 41 opposite to the outside surface of the peripheral wall 102. The elastic element 43 includes at least one latching portion 431. In this embodiment, there are four latching portions 431 and the latching portions 431 can be hooks. A through hole 433 is defined in the middle of the elastic element 43. The latching portions 431 protrude from the edge of the through hole 433 and are inclined towards the through hole 433. At least one positioning hole 435 is defined in the elastic element 43. The jack element 41 further includes at least one protrusion 413 corresponding to the at least one positioning hole 435. In this embodiment, there are two positioning holes 435 and two protrusions 413. The elastic element 43 can be secured to the jack element 41 through the two protrusions 413 engaging in the positioning holes 435.
As illustrated, at least one receiving slot 415 corresponding to the at least one latching portion 431 is defined and recessed in a bottom surface of the jack 411. The at least one receiving slot 415 communicates with the jack 411 and is configured to releasably receive the latching portions 431.
The sealing member 45 is secured in the stepped recess 17 and seals gaps between the electronic element 50 and the jack element 41 when the electronic element 50 is received in the jack 411. In this embodiment, the sealing member 45 can be made of resilient materials, such as rubber, sealing cushion.
The connector 47 is positioned on a side of the circuit board 20 and is electronically connected to the circuit board 20. The connector 20 includes a port 471. The port 471 is aligned with the assembling hole 11 and the jack 411. The port 471 is configured to receive the electronic element 50 to form an electrical connection with the electronic element 50.
As illustrated, the electronic element 50 includes a plug 51. The plug 51 defines at least one matching groove 52 corresponding to the latching portion 431. The electronic element 50 is latched in the jack 411 when the latching portion 431 is received in the matching groove 52 and the electronic element 50 is unlatched with the jack 411 when the latching portion 431 slides out of the matching groove 52.

Referring to
In other embodiments, the matching grooves 52 of the electronic element 50 can be omitted. An elastic intensity of the latching portions 431 or an inclined angle of the latching portion 431 can be adjusted to cause the electronic element 50 be latched by elasticity of the latching portion 431 and a friction of the electronic element 50.
The embodiments shown and described above are only examples. Therefore, many such details are neither shown nor described. Even though numerous characteristics and advantages of the present technology have been set forth in the foregoing description, together with details of the structure and function of the present disclosure, the disclosure is illustrative only, and changes may be made in the detail, including in matters of shape, size and arrangement of the parts within the principles of the present disclosure up to, and including the full extent established by the broad general meaning of the terms used in the claims. It will therefore be appreciated that the embodiments described above may be modified within the scope of the claims.
