[Embodiment] The present invention discloses a portable electronic device casing, which is suitable for a mobile phone or a personal digital assiunt (pDA) portable electronic device. The preferred embodiment of the present invention uses a mobile phone 2 as an example 200917932. Description. Referring to FIG. 3, the mobile phone 20 includes a first housing 22, a second housing 24, and a hinge 26. The hinge 26 hinges the first housing 22 and the second housing 24 together. The second casing 24 includes an upper casing 242, a button soft board 244, a circuit board 246, a lower casing 248, and a plurality of holding members (not shown). The button soft board 244 is held on the upper case 242. The lower case 248 houses the circuit board 246 therein. The upper case 242 and the lower case 248 are engaged with each other and are fixed by the holding member. In this embodiment, the holding member is a bolt. The upper casing 242 includes a button carrier plate 2422 and a joint portion 2424. The button carrier plate 2422 is substantially a flat plate body which is made of metal and is preferably a conductive metal such as iron, iron or alloy. A button hole 2423 is formed in the button carrier board 2422. The joint portion 2424 is made of a plastic material. The upper portion 242 is integrally formed with the button carrier plate 2422 by in-mold injection, and the joint portion 2424 is formed on the periphery of the button carrier plate 2422. The joint portion 2424 is provided with a plurality of protrusions (not shown) and a plurality of card holding holes 2425. The joint portion 2424 is engaged with the lower casing 248 by the tenon and then fixed to the lower casing 248 by the retaining hole 2425. The button soft board 244 is substantially a flat body, and its shape and size are substantially equivalent to the key carrying board 2422. The button soft board 244 is provided with a plurality of buttons 2442 for inputting numbers, characters, and the like. The button 2442 is disposed corresponding to the keyhole 2423. The button soft board 244 is attached to the key carrier board 2422 in such a manner that the button 2442 is slidably received in the button hole 2423. 8 200917932 The circuit board 246 is substantially a flat body, and its shape and size are substantially equal to those of the button flexible board 244. Circuit board 246 has a top surface 2462 and a bottom surface 2464 opposite the top surface 2462. The member surface 2462 is provided with a complex signal sensing portion 2466. The signal sensing unit 2466 is corresponding to the button 2442 of the button soft board 244. g: When the button 2442 is pressed, the button 2442 then presses the corresponding signal sensing portion 2466, and the circuit of the circuit board 246 is briefly turned on, thereby generating an electrical signal. The lower casing 248 includes a left hair 2481, a right wall 2482 opposite the left wall 2481, a front wall 2482 adjacent to the left wall 2481, and a rear wall 2484. The left wall 2481, the right wall 2482, the front wall 2482 and the rear wall 2484 are connected in a square casing and form an accommodation chamber 2485. The accommodating chamber 2485 is for accommodating the circuit board 246. The lower case 248 is provided with a plurality of recesses (not shown) corresponding to the tenons, and the lower case 248 is engaged with the upper case 242 by the engagement of the recesses with the tenons. A plurality of holding posts 2486 are disposed on the corresponding holding holes 2425 of the lower case 248. In the embodiment, a threaded hole (not shown) is formed in the holding post 2486. The retaining post 2486 of the lower casing 248 is received in the retaining hole 2425 of the upper casing 242, and the bolt is screwed into the threaded hole of the retaining post 2486 to prevent the retaining post from being disengaged from the latch. The hole ' thus holds the upper 242 and the lower 248. Referring to FIG. 4 and FIG. 5 , when the second casing 24 of the mobile phone 20 is assembled, the circuit board 246 is first placed in the receiving chamber 2485 of the lower casing 248 with the signal sensing portion 2466 away from the lower casing 248. Then, the button soft plate 244 is fixed on the upper case 242, and the button 2442 is aligned with the button hole 2223. In this embodiment, the button soft board 244 is adhered to the upper case 242 200917932; The upper cover 242 of the soft board 244 is disposed on the lower case 248, and the holding post 2486 of the lower case 248 is received in the holding hole 2425 of the upper case 242. At this time, the holding member is clamped on the holding column. The second housing 24 of the mobile phone 20 is assembled on the 2486 to thereby hold the upper case 242, the button soft board 244, the circuit board 246 and the lower case 248. It can be understood that the holding member can be omitted, and the upper case 242 and the lower case 248 are held by the interference fit of the holding hole 2425 and the holding post 2486. It can be understood that the button soft board 244 and the upper case 242 can also be held in other manners, such as a screw connection. It can be understood that the button carrier plate 2422 can be electrically connected to the grounding end (not shown) of the circuit board 246 by a conductive component (not shown) to ground the static electricity generated by the upper casing 242, thereby protecting the circuit board 246. Electronic components (not shown). The upper casing 242 of the second casing 24 of the mobile phone 20 includes a button carrier plate 2422 and a joint portion 2424', and the button carrier plate 2422 and the joint portion 2424 are integrally formed by in-mold injection. In this way, complicated operations such as subsequent assembly and sealing can be eliminated, which greatly increases production efficiency and saves processing costs. Further, since the key carrying plate 2422 is integrally formed in the joint portion 2424 of the upper portion 242, and the key carrying plate 2422 is generally made of a metal material, the structural rigidity of the upper case 242 can be improved. Further, the joint portion 2424 of the upper case 242 is made of a plastic material, and thus, the joint portion 2424 is formed to form the tenon that is engaged with the lower case 248. In summary, the present invention complies with the requirements of the invention patent and submits a patent application according to law. However, the above description is only a preferred embodiment of the present invention, and the scope of the present invention is not limited to the above embodiments, and those skilled in the art will be able to modify the equivalent modifications of the spirit of the present invention.
