The present invention relates to a housing structure in which a camera module is embedded, and more particularly, a housing for embedding a camera module mounted on a portable terminal is manufactured in a rhombus shape, and thus the hook fastening structure is improved, thereby assembling the camera module housing. The present invention relates to a camera module housing capable of providing a camera module mounting structure capable of meeting the design of an improved and slimming portable terminal.

Nowadays, portable terminals such as mobile phones and PDAs are being used for multi-convergence with music, movies, TV, and games as well as simple telephone functions with the recent development of the technology. As a camera module (CAMERA MODULE) is the most representative. The camera module is being changed from the existing 300,000 pixels (VGA level) to the high pixel center of 7 million pixels and is being changed to implement various additional functions such as auto focusing (AF) and optical zoom (OPTICAL ZOOM).

In general, the camera module (CCM: COMPACT CAMERA MOUDULE) is compact and is applied to various IT devices such as camera phones, PDAs, smartphones, portable mobile communication devices and toy cameras (TOY CAMERA). Increasingly, devices equipped with small camera modules are gradually being released to meet various consumer tastes.

Such a camera module is manufactured using an image sensor such as a CCD or a CMOS as a main component, and collects an image of an object through the image sensor and stores it as data in a memory in the device, and the stored data is stored in the LCD or PC in the device. Displayed as an image through a display medium such as a monitor.

On the other hand, in recent years, the basic form of the portable terminal is a sliding type terminal that horizontally opens and closes by combining a folder equipped with a keypad and a folder equipped with an LCD in a clamshell terminal which opens and closes the upper and lower folders centering on the hinge of the center. In addition, the shape of the housing in which the camera module is built is inevitably changed by the exterior design of the portable terminal according to the trend of gradually changing to the portable terminal.

Referring to the drawings shown below the coupling structure of the camera module housing and the housing mounted on a conventional foldable portable terminal as follows.

1 is a perspective view of a conventional foldable portable terminal, Figure 2 is an assembled perspective view of a camera module housing mounted on a conventional portable terminal.

As shown, the conventional foldable portable terminal 100 is connected to the main body 110 having the keypad 111 on the front and the folder cover 120 rotatably coupled at the upper end of the main body 110. It consists of a hinge body (130).

The hinge body 130 is formed in a cylindrical shape and serves as a support for connecting the main body 110 and the folder cover 120 and at the same time rotatable cylindrical module housing 140 is provided on the housing 140 The camera module (not shown) is built into the inside.

The housing 140 is equipped with a glass 160 for protecting the lens and other components of the camera module in front of the camera module, and rotates on one side of the hinge body 130 according to the position of the subject.

As shown in FIG. 2, the assembly structure of the housing 140 has a plurality of fasteners 143 and protrusions 145 formed on each side of the upper and lower casings 141 and 142 having a semicircular cross-sectional structure. The housing 140 having a circular cross-sectional shape is assembled by combining the binding hole 143 and the protrusion 145 while the camera module is embedded between the upper and lower casings 141 and 142.

A plurality of fasteners 143 formed on both sides of the upper casing 141 is formed with a projection fixing hole 144 in the center is inserted into the inner side of the lower casing 142, the inner surface of the lower casing 142 The protrusion 145 formed at the top is elastically tightly coupled to the protrusion fixing hole 144 to complete the assembly of the housing 140.

In the conventional camera module housing 140 having such a structure, the upper and lower casings 141 and 142 are formed in a symmetrical structure to facilitate injection molding, and by simple coupling of the binding hole 143 and the protrusion 145. Although there is an advantage that can be manufactured, when the housing 140 is assembled by the coupling between the binding hole 143 and the projection 145, because the projection fixing hole 144 is formed in the binding hole 143 outside In addition to being vulnerable to shock, as the overall shape of the assembled housing 140 is formed in a cylindrical shape, there is a problem that it is difficult to apply to a slide-type portable terminal mainly released recently.

In addition, when changing the shape of the housing to be mounted on the slim slide-type portable terminal, since the assembly of the housing cannot be made by the coupling of the binding hole 143 and the protrusion 145, the housing assembly structure may be changed according to the shape of the housing. Inevitably, structural problems that can only be changed are pointed out.

Therefore, the present invention was devised to solve the above-mentioned disadvantages and problems raised in the conventional camera module housing, and the housing of the enclosure type having a cross-sectional shape of a rhombus is formed asymmetrically with each other and is cut into upper and lower casings. An object of the present invention is to provide a camera module housing which can be assembled closely by a plurality of hooks and hook coupling holes provided on the side of the casing, thereby improving the assemblability of a housing having an asymmetric shape that is difficult to hook.

The upper casing and the lower casing are formed by extending the substrate coupling shaft to one side, respectively, to form a cylindrical shape by the coupling of the upper and lower casings, and being connected to the camera module seated inside the casing at the central portion of the cylindrical shaft. The flexible part of the printed circuit board (FPCB) is wound to be connected to an external terminal.

The upper casing is provided with a lens coupling hole to which the lens unit of the built-in camera module is coupled in the decor seating portion formed on the upper portion, and at least one hook coupling hole is formed on each side thereof.

In addition, the lower casing has a plurality of hooks protruding from both sides of the module seating portion in which the camera module with the lens portion is mounted on the inner bottom, and protrusions inserted into the hook coupling holes of the upper casing protrude from the tip side of the hook, respectively. Is formed.

Meanwhile, in the upper and lower casings, a casing joint of mutually asymmetrical shapes is combined to form a camera module housing. The casing joint of each casing has a multi-stepped step in which both sides of the casing are joined to each other and the upper casing is in close contact. There is a technical feature in that the housing having a cross-sectional shape of a rhombus shape is assembled by elastically inserting protrusions formed at each hook front end of the lower casing through hook coupling holes formed at each side of the lower casing.

Matters concerning the operational effects including the technical configuration of the camera module housing of the present invention will be clearly understood by the following detailed description with reference to the drawings in which preferred embodiments of the present invention are shown.
