DETAILED DESCRIPTION

The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean “at least one.”

FIG. 1 illustrates an enclosure 10 and a bracket 20 mounted on the enclosure 10.

FIGS. 1-3 illustrate that the enclosure 10 includes a base plate 11 and a side plate 12 substantially perpendicularly connected to the base plate 11. A number of protrusion portions 112 are located on the base plate 11 to support a circuit board 30. A locking hole 113 is defined in a middle portion of each of the number of protrusion portions 112. The locking hole 113 is bound by two opposite first sides 114 and two opposite second sides 115. In one embodiment, a length of each of the two first sides 114 is greater than a length of each of the two second sides 115. Two first through holes 31 are defined in the circuit board 30. An opening 121 is defined in the side plate 12. Two cutouts 122 are defined in the side plate 12 at opposite sides of the opening 121.

The bracket 20 includes a first body 21 and a second body 22 substantially perpendicularly connected to the first body 21. Two locking portions 221 are located on the second body 22. Two locking members 50 are fixed on the first body 21. Four locating holes 211 and two mounting holes 212 are defined in the first body 21. The first body 21 includes a bending tab 213. The bending tab 213 defines a second through hole 214. The bending tab 213 is substantially perpendicularly connected to a bottom edge of the first body 21.

FIG. 4 illustrates that each of the two locking members 50 includes a sliding pole 51, a duct 52, and a spring 53. An annular first limiting portion 511 protrudes from an upper portion of the sliding pole 51. An annular second limiting portion 512 protrudes from a lower portion of the sliding pole 51. A limiting block 513 protrudes from a middle portion of the sliding pole 51. In one embodiment, a diameter of the second limiting portion 512 is greater than a diameter of the second through hole 214.

A resisting block 516 extends from a distal end of the sliding pole 51. The resisting block 516 includes two opposite third sides 517 and two opposite fourth sides 518. In one embodiment, a length of each of the two third sides 517 is less than the length of each of the first sides 114. The length of each of the third sides 517 is greater than the length of each of the second sides 115. A length of each of the fourth sides 518 is less than the length of each of the second sides 115.

FIGS. 2 and 4 illustrate that the duct 52 includes two upright portions 521 substantially parallel to each other, and a connecting portion 522 connected to the two upright portions 521. Each upright portion 521 includes two hook 523 located on a side edge thereof. The two upright portions 521 and the connecting portion 522 cooperatively form an accommodating space 524 therebetween. A mounting tab 525 extends from one of the two upright portions 521. Two fixing holes 526 are defined in the mounting tab 525. A sliding slot 527 is defined in the connecting portion 522. The sliding slot 527 includes an inserting portion 528 and a sliding portion 529. The inserting portion 528 and the sliding portion 529 communicate with each other. In one embodiment, an outer surface of the connecting portion 522 is substantially arc-shaped. A width between the two upright portions 521 is less than a diameter of the first limiting portion 511. The sliding slot 527 is substantially L-shaped.

FIGS. 1-7 illustrate that in coupling of each duct 52 to the bracket 20, the spring 53 is mounted to the lower portion of the sliding pole 51, such that an upper portion of the spring 53 resists against the limiting block 513. The sliding pole 51 is received in the accommodating space 524 of the duct 52. The limiting block 513 extends through the inserting portion 528 of the sliding slot 527. The first limiting portion 511 and the second limiting portion 512 of the sliding pole 51 extend out of the duct 52. The first limiting portion 511 extends out of a first end of the duct 52, and the second limiting portion 512 extends out of a second end of the duct 52.

The hooks 523 of the duct 52 are received in the corresponding locating holes 211 of the bracket 20. The fixing holes 526 are aligned to the corresponding mounting holes 212. A number of fastening members 90 extends through the fixing holes 526 and the mounting holes 212 correspondingly. Thus, the ducts 52 are fixed on the bracket 20, and the resisting blocks 516 of the sliding poles 51 are aligned to the corresponding second through holes 214.

The circuit board 30 is placed on and supported by the number of protrusion portions 112 of the base plate 11. The locking holes 113 are aligned to the first through holes 31. The bending tabs 213 of the bracket 20 are located on the circuit board 30, and the second through holes 214 of the bending tabs 213 are aligned to the corresponding first through holes 31.

The sliding pole 51 is pressed to slide into the duct 52, causing the limiting block 513 to slide along the inserting portion 528, and the resisting block 516 to pass through the second through hole 214 and the first through hole 31. The third sides 517 are aligned to the corresponding first sides 114, and the fourth sides 518 are aligned to the corresponding second sides 115. The resisting block 516 is passed through the locking hole 113, and the spring 53 is elastically deformed. The first limiting portion 511 resists against the first end of the duct 52, and the second limiting portion 512 resists against the bending tab 213.

When the limiting block is at a distal end of the inserting portion connected to the sliding portion 529, the sliding pole 51 is rotated in the duct 52, causing the limiting block 513 to slide along the sliding portion 529. Simultaneously, the resisting block 516 is rotated in the locking hole 113, causing the third sides 517 to misalign with the corresponding first sides 114. The sliding pole 51 is released, allowing the spring 53 to restore partially elastically to an undeformed state. The resisting block 516 resists against a bottom surface of the protrusion portion 112, and the limiting block 513 resists against a side edge of the sliding portion 529. Thus, the sliding pole 51 is prevented from moving out of the duct 52. The two locking portions 221 are locked in the two cutouts 122, and the bracket 20 is fixed on the enclosure 10 together with the circuit board 30.

To disassemble the bracket 20 and the circuit board 30 from the enclosure 10, the sliding pole 51 is rotated in the duct 52. The limiting block 513 slides back to the inserting portion 528 from the sliding portion 529. The resisting block 516 is rotated in the locking hole 113. The third sides 517 are aligned to the corresponding first sides 114, thereby releasing the sliding pole 51 and fully elastically restoring the spring 53. The sliding pole 51 slides out of the duct 52, and the resisting block 516 moves out of the locking hole 113 and the first through hole 31. Thus, the bracket 20 and the circuit board 30 are disassembled from the enclosure 10.

Even though numerous characteristics and advantages of the present disclosure have been set forth in the foregoing description, together with details of the structure and function of the disclosure, the disclosure is illustrative only, and changes may be made in detail, especially in the matters of shape, size, and the 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.
