BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a perspective exploded view of an electronic component assembly structure in accordance with a preferred embodiment of the present invention.

2 is an exploded perspective view showing another angle of the electronic component assembly structure shown in FIG. 1.

FIG. 3 is an assembled view of the assembly structure of the electronic component shown in FIG. 1.

The invention discloses an electronic component assembly structure, which is suitable for a portable electronic device such as a mobile phone and a personal digital assistant. In this embodiment, an electronic component assembly structure applied to the mobile phone is taken as an example for description.

Referring to FIG. 1 and FIG. 2, in the preferred embodiment, the electronic component assembly structure 100 of the present invention is used to fix a plurality of electronic components to a body 20. The electronic component assembly structure 100 includes two positioning members 22 , a circuit board 40 , and a fixing member 60 .

The body 20 can be a metal housing of a mobile phone. In the present embodiment, the positioning member 22 can be formed by cutting or casting, and is fixed to the body 20 by welding or the like. The positioning member 22 includes a disk 24, a connecting portion 26 and a holding portion 28 connected in sequence. The disc 24 is an annular sheet-like body that is welded to the body 20 and protects the body 20 from collisions when the electronic components are fixed. The connecting portion 26 is a cylinder formed by a vertical extension of the inner circle of the disk 24. The holding portion 28 is substantially a ring body having a radial dimension larger than a radial dimension of the connecting portion 26, and the latching portion 28 is slightly smaller than one end of the connecting portion 26 and is connected to the connecting portion. One of 26 The ends form a first guiding surface 282 which can facilitate the securing of the electronic components.

The circuit board 40 is a Flexible Printed Circuit Board (FPC) that is mounted between the fixing member 60 and the body 20. A plurality of electronic components can be disposed on the circuit board 40. In the embodiment, an earpiece 44 and a camera 46 disposed on the circuit board 40 are taken as an example for description. An electrical contact point (not shown) is disposed on the circuit board 40. The earpiece 44 and the camera 46 are electrically connected to the circuit board 40 by the electrical contact point.

The fixing member 60 is substantially a rectangular parallelepiped and is made of an elastic material such as plastic. The fixing member 60 includes a receiving portion 62 and two fixing portions 64 extending from opposite ends of the receiving portion 62.

The receiving portion 62 includes a first surface 68 and a second surface 69 opposite the first surface 68. The first surface 68 is recessed to form a first accommodating cavity 622 and a second accommodating cavity 624. The first accommodating cavity 622 is configured to receive the earpiece 44, and the two are the same in size. The bottom wall of the first receiving cavity 622 defines an acoustic opening 626 extending through the second surface 69. The sound port 626 is used to transmit the sound emitted by the earpiece 44 to the outside. The second accommodating cavity 624 is configured to receive the camera 46, and the two shapes are the same. The bottom wall of the second accommodating cavity 624 defines a through hole 628 extending through the second surface 69. The through hole 628 is configured to pass light, so that external light can enter the camera 46.

The height of the fixing portion 64 is lower than the accommodating portion 62 , and the bottom surface of the fixing portion 64 is flush with the first surface 68 of the accommodating portion 62 . A fixing hole 642 is formed in the fixing portion 64 to engage with the positioning member 22 . The fixing hole 642 includes a notch 644, a positioning hole 646 and a groove 648. The notch 644 and the groove 648 are located at the The two ends of the positioning hole 646 are defined, and the notch 644 is opened at one end of the fixing portion 64. The notch 644 and the groove 648 can provide space for the elastic deformation of the fixing portion 64. Since the fixing portion 64 is made of an elastic material, when the fixing portion 64 is pressed, the notch 644, the positioning hole 646 and the groove 648 are deformed to make the fixing hole 642 large. The radial dimension of the locating aperture 646 is slightly smaller than the radial dimension of the retaining portion 28 when uncompressed. A second guiding surface 66 is disposed on the outer circumference of the fixing hole 642. The second guiding surface 66 can facilitate the cooperation of the fixing hole 642 and the positioning member 22.

As shown in FIG. 3, during installation, the first accommodating cavity 622 and the second accommodating cavity 624 of the fixing member 60 are respectively aligned with the earpiece 44 and the camera 46, and the positioning hole 646 is aligned with the positioning. Then, the fixing portion 64 of the fixing member 60 is pressed downward. Since the fixing portion 64 is made of an elastic material and a notch 644 is formed at one end thereof, the fixing portion 64 is elastically deformed to make a positioning hole. The 646 becomes larger and passes through the catch portion 28. Thereafter, the fixing portion 64 is elastically deformed and clamped on the holding portion 28, so that the earpiece 44 and the camera 46 are fixed to the body 20.

It can be understood that the positioning hole 646 can be other shapes, such as a square hole, and the connecting portion 26 and the holding portion 28 are square cylinders.

The electronic component assembly structure 100 of the present invention fixes the earpiece 44 and the camera 46 to the body 20 by the cooperation of the positioning member 22 and the fixing hole 642, and the assembly process is convenient.

In summary, the present invention complies with the requirements of the invention patent and submits a patent application according to law. The above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited to the above-described embodiments, and equivalent modifications or variations made by those skilled in the art in accordance with the spirit of the present invention are It should be covered by the following patent application.
