The present invention relates to a deco-coupling structure of the housing in which the camera module is built, and more particularly, by combining the deco manufactured to be provided with a plurality of hooks on the bottom by double injection through the upper opening of the housing for the camera module to be built in. The present invention relates to a deco assembly structure of a camera housing to ensure the reliability of the product as the falling of the deco from the housing.

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 form in which the camera module is mounted on the portable terminal has been diversified into a structure in which the camera module is integrally inserted into and fixed to the inside of the portable terminal and the externally mounted structure including the hinge portion of the clamshell terminal. When mounted, the camera module is mounted using a cylindrical housing mounted on the hinge portion of the portable terminal as shown in FIGS. 1 and 2.

1 is a perspective view of a conventional foldable portable terminal, and FIG. 2 is a partial perspective view of a camera module housing mounted on a conventional portable terminal. As illustrated, the conventional foldable portable terminal 100 has a keypad 111 at the front thereof. It consists of a hinge body 130 for connecting the main body 110 is provided with a folder cover 120 rotatably coupled at the upper end of the main body 110.

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 with 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.

At this time, the housing 140, the lens coupling hole 142 is coupled to the lens unit of the camera module on the upper casing 141 having a semi-circular cross-sectional shape as shown in FIG. ) Is provided, the deco 144 for covering the beauty of the appearance of the housing 140 and the lens coupling hole 142 on the decor seating portion 143 is bonded by the application of an adhesive.

In order to couple and fix the deco 144 to the camera module housing 140, an adhesive is applied to the outer circumferential surface contact portion of the deco seating part 143 and the deco 144 as shown in FIG. 2, or both sides of the deco 144 may be double-sided. Although the deco 144 is fixed to the deco seat 143 by attaching a tape, the deco 144 is easily deteriorated due to the performance of the adhesive applied to the adhesive site or the lack of the adhesive site due to external impact. Disadvantages are noted.

In order to solve this disadvantage, as shown in FIG. 3, at least two bosses 150 are formed on the bottom of the deco 144 coupled to the top of the camera module housing 140, and the deco 144 is formed. The boss coupling hole 143a is provided on the deco seating portion 143 of the housing 140 to which the housing 140 is coupled, so that the boss 150 is coupled to the boss 150 after the deco 144 is coupled to the deco seating portion 143. Make sure that the fixing is done.

Coupling of the boss 150 is bonded so that the deco 144 is not separated on the deco mounting portion 143 by applying an adhesive to the boss 150 coupling site or by thermal fusion of the boss 150 using a separate device. do.

However, this coupling method has an advantage of permanently fixing the deco 144 on the housing 140, but at least four bonding areas of the deco seating portion 143 and the deco 144 are located. As described above, if the heat fusion process is added, there is a problem in that the cost of the bonding material cost for the decoupling and the cost of the terminal for manufacturing the terminal increases due to the addition of the heat fusion process.

In addition, there is a disadvantage in that the assembly failure of the housing 140 is increased by the possibility that the adhesive is applied on the lens portion including the lens portion as the adhesive portion increases during the bonding operation of the deco 144.

Accordingly, the present invention has been made to solve the above-mentioned disadvantages and problems raised in the decor assembly structure of the conventional housing, a plurality of binding grooves are provided on the inner circumferential surface of the upper lens coupling hole of the housing in which the camera module is built, A plurality of hooks protrude from the bottom of the deco to be coupled to the top of the housing so that the deco can be tightly coupled by the elasticity of the hook, so that the deco is fixed to the top of the housing without the adhesive. An object of the present invention is to provide a deco assembly structure of a camera housing so that the productivity of the housing assembly line can be improved by shortening the time.

The above object of the present invention, the lens coupling hole and the deco mounting portion is provided on the upper casing and the inner casing of the plurality of coupling grooves formed on the inner peripheral surface of the lens casing, the inner casing of the upper casing is fixed in the inner peripheral portion It is achieved by providing a deco assembly structure of the camera module housing including a deco the hook of the protruding and the circular elastic body tightly coupled to the bottom surface of the lens coupling hole of the upper casing.

At this time, a deco formed with a plurality of hooks protruding from the deco mounting portion of the upper casing is seated, the hook of the deco is inserted into the lens coupling hole is elastically tightly coupled to the binding groove provided on the inner peripheral surface of the lens coupling hole. By this, the upper casing and the deco are combined.

The deco is formed by double injection molding a plurality of hooks protruding into the body portion and the bottom of the deco, the body portion of the deco is plated so that the appropriate color is expressed according to the color of the housing and the hook is elastic At least two or more are provided in a state.

The upper casing of the housing to which the deco is coupled is provided with a circular lens coupling hole to the inside of the deco mounting portion in which the outer peripheral surface of the deco is in close contact, and a plurality of binding grooves to which the hook of the deco is correspondingly formed on the inner circumferential surface of the lens coupling hole. do.

In addition, the deco is inserted and mounted through the deco seating portion of the upper casing is fixed by the elastic coupling of the hook and the binding groove described above, a circular cover inside the binding portion of the hook and the binding groove through the rear of the upper casing. Glass is mounted, and a circular elastic body is attached to compensate for the height difference between the cover glass and the hook inner surface.

The present invention configured as described above is coupled to the lower casing having a semi-circular cross-section through the upper deco seating portion of the upper casing constituting the housing, the deco is made only by the elastic coupling of the hook on the deco mounting portion without the adhesive means including a separate adhesive As a result, the technical characteristics are that the assembly time can be shortened and the manufacturing cost of the product can be reduced by reducing materials and reducing the number of processes.
