Description

Shield and manufacturing method thereof

The invention relates to a shielding cover and a manufacturing method thereof, in particular to a partial shielding cover of a camera module and a manufacturing method thereof.

With the rapid development of economy and technology and the improvement of people's living standards, the use of various portable electronic devices such as mobile phones and personal digital assistants (PDAs) has become more and more popular in people's lives. The use of portable electronic devices such as mobile phones and PDAs with camera functions has become more and more widely used to meet the needs of consumers for camera and video functions of portable electronic devices such as mobile phones and PDAs. A camera module is mounted in the electronic device. In order to prevent electromagnetic interference (EMI) in circuit applications and affect the performance of the camera module in the entire portable electronic device, a shield cover made of a conductive material is usually provided on the cover of the camera module for preventing Electromagnetic interference.

In addition, in order to protect the portable electronic device from being impacted, dropped, etc., it is not damaged to the camera module mounted therein. The conventional technical solution is generally used to fill the camera module and the shield cover with foam or rubber. The substance protects the camera module from shock and damage. However, in the above solution, it is necessary to manually assemble the foam or the rubber with the cover body, which not only increases the assembly step, but also cannot achieve a good seal because the dust easily enters the camera module through the filled foam or rubber gap. Effect The shooting quality of the portable electronic device.

In view of this, it is necessary to provide a shield that is simple and compact in structure and that protects the camera module from damage and prevents electromagnetic interference.

In addition, it is also necessary to provide a method of manufacturing the shield.

A shield cover includes a cover body and a pad, the pad is embedded on the cover body, and the pad is integrally formed with the cover body by in-mold molding.

A method for manufacturing a shield cover, comprising the steps of: providing a mold; providing a cover body into the mold; injecting a molded soft body material into the mold to form a pad, and the cover body Formed integrally with the pad; after cooling, the mold is opened, and the cover and the pad are taken out to form the shield.

Compared with the prior art, the shielding cover is manufactured by an in-mold integrated manufacturing method, which reduces the design and assembly steps of the disassembling parts, and also achieves a sealing effect, thereby better protecting the camera module from the camera module. Impact, damage.

1 is a perspective view of a preferred embodiment of the shield of the present invention; FIG. 2 is a perspective view of another embodiment of the shield of the present invention; FIG. 3 is an exploded view of the shield shown in FIG. 1; An exploded view of the shield shown.

Referring to FIG. 1 and FIG. 2, the shield cover 100 of the preferred embodiment of the present invention is used to protect the camera module of the portable electronic device from rushing and shielding electromagnetic interference. The shield cover 100 includes a cover 10 and a cover. The cover 10 is integrally formed with a pad 20 in the mold.

Referring to FIG. 3 and FIG. 4 together, the cover body 10 is a stamped or bent metal member, and includes a top wall 11 and a first side wall 12 and a second side wall 13 disposed perpendicular to the top wall 11. The third side wall 14 and the fourth side wall 15 are provided. The top wall 11 , the first side wall 12 , the second side wall 13 , the third side wall 14 , and the fourth side wall 15 define an accommodating space 16 that is closed at one end and opened at the other end. The accommodating space 16 is used for accommodating the camera. Module (not shown). The top wall 11 is rectangular, and a rectangular through hole 112 is defined at a central position thereof. A plurality of circular through holes 115 are defined in the edge of the top wall 11 to facilitate the mounting of the shielding cover 100 and the components of the portable electronic device or the camera module mounted in the shielding cover 100. Electrical connection of components in the portable electronic device. A strip-shaped opening 113 extending to the first side wall 12, the second side wall 13, the third side wall 14, and the fourth side wall 15 is formed at a substantially intermediate position of each of the sides of the top wall 11 that surrounds the rectangular through hole 112. A rectangular through slot 132, 152 is defined in the second sidewall 13 and the fourth sidewall 15 opposite thereto, so that the shield 100 can be fixed to the components of the portable electronic device or can be easily mounted on the shield 100. The camera module is electrically connected to each component in the portable electronic device.

The pad 20 and the cover 10 cooperate with each other and are integrally molded with the cover 10 by in-mold molding. The pad 20 is embedded in the cover 10 . The pad 20 includes a rectangular ring 22, a beam wall 23, a mating wall 24, and a positioning post 25. The rectangular ring 22 is a rectangular annular body having a size corresponding to the rectangular through hole 112 formed in the top wall 11 of the cover body 10 and closely fitting with each other. The beam wall 23 is substantially midway between each side of the rectangular ring 22. The placement extends outwardly and corresponds to and closely fits the strip-shaped slits 113 of the top wall 11 of the cover 10. The mating wall 24 has a rectangular plate shape, and the end of the beam wall 23 extends along the four side walls of the cover body 10 and the first side wall 12, the second side wall 13, and the third side of the cover body 10.
