DETAILED DESCRIPTION
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 “coupled” is defined as connected, whether directly or indirectly through intervening components, and is not necessarily limited to physical connections. The connection can be such that the objects are permanently connected or releasably connected. The term “substantially” is defined to be essentially conforming to the particular dimension, shape, or other feature that the term 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 following disclosure is described in relation to electronic device with securing structure for printed circuit board.
FIG. 1 illustrates an embodiment of an electronic device 100. The electronic device 100 includes a housing 10 and a cover 20 detachably covered on one end of the housing 10.
FIGS. 2 and 5 illustrates that the housing 10 is configured to form a cavity, an opening 12, and a first interior surface opposite the opening 12. The electronic device 100 further includes at least two securing structures 30. Each of the securing structure 30 includes a flange 11 and a support block 40. The flange 11 extends inward into the cavity from the first interior surface, the flange 11 has an outer end furthest from the interior surface. The support block 40 is attached to an edge of the flange 11. The support block 40 is in a shape of “H”. The support block 40 includes a first rib 41, a second rib 42 opposite to and parallel to the first rib 41, and a connector element 43 located between, and perpendicular to the first rib 41 and the second rib 42. At least one support block 40 is attached to the outer end of the flange 11 with the first rib 41 and second rib 42 substantially parallel to the flange 11. In the illustrated embodiment, at least one securing structure 30 is located inside the housing 10, and at least one securing structure 30 is located inside the cover 20. The cover 20 includes another flange 11 and another support block 40 attached to an edge of the another flange 11. The another block 40 includes another first rib 41, another second rib 42 opposite to and parallel to the another first rib 41, and another connector element 43 located between, and perpendicular to the another first rib 41 and the another second rib 42.
FIGS. 3-4 illustrate that the printed circuit board 50 is in a shape of rectangle. The printed circuit board 50 defines two first notches 51 in an end of the printed circuit board 50 adjacent to the flange 51, and a second notch 52 on another end of the printed circuit board 50, opposite to the first notch 51 and adjacent to the opening 12. One end of the printed circuit board 50 can be insertable within the connector element 43 to position the printed circuit board on the housing 10. The other end of the printed circuit board 50 opposite to the housing 10 can be insertable within the connector element 43 to position the printed circuit board 50 on the cover 20.
FIGS. 5-6 illustrate that the housing 10 further includes a pair of rails 13 located on two sides of the housing 10 and perpendicular to the flange 11. In assembly, first, the printed circuit board 50 slides along the rails 13 into the housing 10 until the connector element 43 is inserted into the first notches 51 allowing the first rib 41 and the second rib 42 of the housing 10 support one end of the printed circuit board 50. Secondly, the cover 20 is put over the opening 12 of the housing 10 so that the printed circuit board 50 is insertable into the connector element 43 of the cover 20 in the second notch 52 allowing the first rib 41 and the second rib 42 of the cover 20 support the other end of the printed circuit board 50. When the connector element 43 of the housing 10 is inserted into the first notch 51 and the connector element 43 of the cover 20 is inserted into the second notch 52, the printed circuit board 50 is securely fixed in the electronic device 100.
When the electronic device 100 is disassembled, first, the cover 20 is opened to disengage the second notch 52 from the connector element 43. Second, the printed circuit board 50 can be pulled out of the housing 10.
Many details are often found in the art such as the other features of a structure to fix a printed circuit board. 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, especially 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.
