1. Technical Field
The present disclosure relates to protective cover mechanisms for protecting, for example, USB interfaces.
2. Description of Related Art
Portable electronic devices such as mobile phones are widely used. Universal Serial Buses (USBs) are commonly assembled to the electronic devices. To prevent contaminants from entering into the inside of electronic devices through the USB interfaces, protective cover mechanisms are provided. However, the protective cover mechanisms are usually complex in structure and difficult to fabricate with the electronic devices.
Therefore, there is room for improvement within the art.
Many aspects of the present protective cover mechanism can be better understood with reference to the following drawings. The components in the various drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present protective cover mechanism. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the diagrams.

The cover head 10 includes a head portion 12 connected to a connecting portion 14. The head portion 12 has two adjacent arcuate surfaces 122 and an aperture 124 defined through the two arcuate surfaces 122. A decorative article can be attached to the cover mechanism 100 by passing a fastener such as a string or chain through the aperture 124 that is connected to, for example, a charm or key fob. The connecting portion 14 protrudes from the head portion 12 opposite to the two arcuate surfaces 122. The connecting portion 14 defines a recess 142 which is enclosed by a peripheral wall 144. The peripheral wall 144 defines two opposite through holes 1442.
A positioning member 146 and two latching members 148 extend from a surface of the recess 142 to outside of the recess 142. The positioning member 146 is located in the center of the recess 142 and includes a central pole 1462 and two peripheral poles 1464 arranged symmetrically about the central pole 1462. The central pole 1462 and the two peripheral poles 1464 are used to fix the cover head 10 to the cover body 20.
The two latching members 148 are oppositely arranged on the two sides of the recess 142 and adjacent to the peripheral wall 144. Each latching member 148 includes a latching block 1482 and two parallel guiding blocks 1484 on two opposite sides of the latching block 1482. The latching block 1482 includes a block portion 1486 and a hook portion 1488 laterally extending from the block portion 1486. The hook portion 1488 is wedge-shaped for latching to the cover body 20. The guiding block 1484 is used to guide the cover head 10 to latch to the cover body 20.
The hollow cover body 20 includes a tube wall 22, a cavity 24 surrounded by the tube wall 22, and an engaging member 26 connected to the tube wall 22 in the cavity 24. The tube wall 22 has two ribs 222 and two groups of protuberances 224 at the interior surface. The two ribs 222 are configured to latch with the two latching members 148. Each group has two protuberances 224 arranged at a planar interior surface of the cover body 20.
The engaging member 26 includes a plate portion 262 and two connecting portions 264 connected to the interior wall of the tube wall 22. The plate portion 262 defines a central hole 2622 and two peripheral holes 2624 for receiving the central pole 1462 and two peripheral poles 1464 respectively. The connecting portions 264 are configured for engaging in the holes 1442 of the cover head 10.
