1. Technical Field
The present disclosure relates to electronic assemblies, and more particularly to an electronic assembly having a cover which can be assembled or disassembled more easily.
2. Description of Related Art
The conventional electronic assembly includes a rack and a case mounted on the rack. The case includes a cubical, hollow supporting housing and a cover. The supporting housing defines an opening at a top side thereof and receives a plurality of electronic components therein. The cover is mounted on the top side of the supporting housing by a plurality of screws to cover the opening of the supporting housing. When the electronic components, which is received in the supporting housing, need to be replaced or maintained, a worker then disassembles the screws from the electronic assembly one by one, and thereby detaching the cover. When the electronic components are replaced or maintained as a whole in one unit, the cover is assembled to the supporting housing by means of the screws again. The processes of assembly or disassembly of the cover are thereby time-consuming.
It is thus desirable to provide an electronic assembly which can overcome the described limitations.

The supporting housing 31 includes a rectangular bottom plate 310, two elongated and parallel first sidewalls 311 extending upwardly from the lateral ends of the bottom plate 310, respectively, and two parallel and elongated second sidewalls 312 extending upwardly from the front and rear ends of the bottom plate 310, respectively. The first sidewalls 311 and the second sidewalls 312 perpendicularly connect to the bottom plate 310. The first sidewalls 311, the second sidewalls 312 and the bottom plate 310 cooperatively define a receiving chamber (not labeled) to receive a plurality of electronic components (not labeled) therein. A top portion of an outer surface of each of the first sidewalls 311 is recessed along a longitudinal direction of the first sidewall 312 to define a V-shaped groove 314 therein. The groove 314 receives a part of the cover 33 therein when the cover 33 is mounted on the supporting housing 31 so as to avoid the cover 33 and the supporting housing 31 interfering with each other. Two tracks 316 extend outwardly from the top ends of the two first sidewalls 311, along opposite horizontal directions, respectively. The track 316 is an L-shaped sheet and is located at a top portion of a corresponding groove 314. Each of the track 316 includes an elongated first stretching portion 3162 extending outwardly from the top end of the first sidewall 311 and a second stretching portion 3163 extending downwardly from an outer edge of the first stretching portion 3162. The first stretching portions 3162 are away from and parallel to each other. A baffle portion 318 extends rearward from a top end of a frontal section of the second sidewalls 312. The baffle portion 313 is an elongated sheet, and is perpendicularly connected to the second sidewall 312.
The cover 33 includes a body 331, two slideways 334, a securing member 335 and two clips 336. The body 331 is a rectangular sheet. The two slideways 334 are formed on the lateral sides of the body 331. Each of the slideway 334 has an L-shaped configuration, and includes a first extending edge 332 extending downwardly from one lateral edge of the body 331 and a second extending edge 333 extending inwardly from a bottom end of the first extending edge 332. The first extending edges 332 face each other and are parallel. The second extending edges 333 are oriented toward each other and are parallel. A width of the first extending edge 332 along a vertical direction is larger than that of the second stretching portion 3163 of the track 316 of the supporting housing 31. Thus, the second stretching portion 3163 is enclosed by the first extending edge 332 and the second extending edge 333 when the cover 33 is mounted on the supporting housing 31. Two blocking portions 337 extend inwardly from a plurality of inner edges of top ends of the two second extending edges 333, respectively. The blocking portion 337 is a rectangular piece to clasp the guideway 40. The securing member 335 extends downwardly from a central portion of a rear end of the body 331. The securing member 335 is a rectangular piece. The clips 336 extend rearward from a front end of the body 331 and are located at the lateral sides of the front end of the body 331, respectively. Each of the clips 336 includes an engaging plate 3361 extending rearward from the front end of the body 331 and two spaced elastic engaging portions 3363 extending downwardly from the engaging plate 3361. Only the rear ends of the elastic engaging portions 3363 are connected to the engaging plate 3361.

A width of the second transition portion 45 is smaller than that of the first transition portion 43. A length of the first spreading portion 42 is equal to that of the second spreading portion 44, the first transition portion 43, the second transition portion 45, and to that of the mounting member 41, respectively. Front and rear ends of the first spreading portion 42, and the second spreading portion 44, the first transition portion 43 and the second transition portion 45 define two parallel planes, respectively. The first spreading portion 42, the second spreading portion 44, the first transition portion 43 and the second transition portion 45 cooperatively define a guiding groove 47 to receive the second extending edge 333 of the slideway 334 of the cover 30. Two first guiding plates 441 extend from the front and rear ends of the second spreading portion 44 in a slantwise manner and are oriented toward the first spreading portion 42. In addition, two second guiding plates 451 extend from the front and rear ends of the second transition portion 45 in a slantwise manner, and are oriented toward the first transition portion 43. Each first and second guiding plate 441, 451 is a rectangular plate, and guides the cover 33 when sliding along the guideways 40.

The mounting members 41 are mounted on central portions of the inner surfaces of the connecting arms 20 so as to make the two guiding members 46 orient toward the opposite directions and to aim at the second extending edges 333 of the slideways 334 of the cover 33, respectively. In this state, a gap 60 is defined between the front ends of the guideways 40 and the rear end of the supporting housing 31. A length of the gap 60 along the longitudinal direction of the second extending edge 333 of the slideway 334 is smaller than a length of the slideway 334. Therefore, the cover 33 will engage with the guideways 40 when a part of the cover 33 engages with the supporting housing 31 to avoid the cover 33 from falling off through the gap 60. A length of the blocking portion 337 along the longitudinal direction of the second extending edge 333 is smaller than the length of the gap 60.
