As shown in FIGS. 3 to 5, the clamshell mobile communication terminal A according to the present invention includes a main body 10 having a hinge cylinder 12 protruding a predetermined portion at a center of an upper end thereof, and a main body 10 of the main body 10. A folder 20 having a set of hinge knuckles 22, 22 'facing each other on both sides of the lower end so as to be coupled to the hinge cylinder 12, and rotatably connected to the main body 10 and the folder 20. Is configured to include a hinge 30, and a rolling prevention device 40 for preventing the hinge of the hinge (30).

Here, the main body 10 is formed of a structure in which various circuit elements, a keypad assembly, a transmitter, and the like can be seated, and a predetermined portion protrudes in the center of the upper end thereof, the first body housing 11 having a hinge cylinder 12. And a second body housing 11 ′ which closes the open surface of the first body housing 11.

In addition, one side of the hinge cylinder 12 is provided with a first hinge groove 12a, and the other side is provided with an insertion groove 12b having the same central axis as the first hinge groove 12a.                     

On the other hand, the rear upper end of the first body housing 11 constituting the main body 10 communicates with the first hinge groove 12a of the hinge cylinder 12, thereby adjusting the position of the hinge 30 is installed The assembly hole 13 is provided, and a set of guide ribs 13a are provided at the center of the assembly hole 13 to prevent the flow of the rolling prevention tool 40 to be described later.

The folder 20 has a shape substantially similar to that of the main body 10, and a pair of hinge knuckles 22 and 22 ′ facing each other are coupled to both sides of the lower end so as to be coupled to the hinge cylinder 12 of the main body 10. The second folder housing 21 'which is provided with a first folder housing 21 and an open surface of the first folder housing 21 and which has various circuit elements, a liquid crystal screen and a receiver, is formed thereon. Formed by dividing).

In addition, one of the hinge knuckles 22 and 22 ′ of the hinge knuckles 22 and 22 ′ of the first folder housing 21 has a second hinge groove at a position corresponding to the first hinge groove 12a of the main body 10. 21a) is provided, and the other hinge knuckle 22 'is provided with a dummy hinge 21a' at a position corresponding to the insertion groove 12b of the main body 10.

The hinge 30 includes a main body inserting portion 31 having a shape that can be inserted into the first hinge groove 12a provided in the hinge cylinder 12 of the main body 10, and a hinge provided at the lower end of the folder 20. It is divided into a folder inserting portion 32 having a shape that can be inserted into the second hinge groove 21a of the knuckle 22, and the main body inserting portion 31 and the folder inserting portion ( 32) is formed in a structure that can be rotated individually, such a hinge is applied to the same hinge as the commonly used hinge, detailed description of the internal structure and operation will be omitted.                     

The anti-roll 40 is provided in the first hinge groove 12a provided in the hinge cylinder 12 of the main body 10 and the second hinge groove 21a provided in the hinge knuckle 22 of the folder 20. The hinges 30 respectively inserted and installed are installed to prevent the hinges 30 from being removed from the second hinge grooves 21a and moved to the first hinge grooves 12a.

That is, the anti-roll 40 is a rectangular body 41 made of a plate-shaped, a set of fixing pieces 42 and the fixing piece 42 arranged at a predetermined interval on one surface of the body 41, Consists of a fixing protrusion 43 protruding to the outer side of the front end of the first body housing 11, inserted between the set of guide ribs (13a) provided in the assembling hole 13 of the first body housing 11, after the fixing piece By the fixing protrusion 43 provided in the outer side of the tip end 42, it is possible to maintain a fixed state in the assembly hole (13).

At this time, the width of the fixing piece 42 made of a set is preferably equal to or slightly smaller than the width of the assembly hole 13 provided in the first body housing 11 so that it can be fixed due to its elasticity. Do.

A method of assembling the hinge 30 of the mobile communication terminal A according to the present invention is as follows.

First, the hinge 30 is inserted into the first hinge groove 12a of the hinge cylinder 12 provided in the first body housing 11. At this time, the hinge 30 is inserted into the main body insertion portion 31 and the folder insertion portion 32 in the first hinge groove 12a is not exposed to the outside.

In this state, the hinge knuckles 22 and 22 'of the folder 20 and the hinge cylinder 12 of the main body 10 are coupled, but the dummy hinge 21a' of the folder 20 is inserted into the insertion groove 12b. It is combined with the inserted state. In such a state, only the dummy hinge 21a 'is combined, and the hinge 30 is positioned in an inserted state of the first hinge groove 12a, and the rear surface of the first body housing 11 is formed. It is possible to check the insertion state of the hinge 30 through the assembly hole 13 provided in the.

In this state, the user uses a tool such as a hinge assembly jig to insert the folder inserting portion 32 of the hinge 30 inserted into the hinge barrel 12 into the second hinge groove 22a of the hinge knuckle 22. To the side.

When the hinge 30 is pushed in this way, the entirety of the hinge 30 is moved and the folder inserting portion 31 is inserted into the second hinge groove 21a of the hinge knuckle 22, and the first of the hinge cylinder 12 Since only the main body inserting portion 31 is inserted into the hinge groove 12a, the main body inserting portion 31 and the folder inserting portion 32 of the hinge 30 can be rotated separately from each other. 10) and the folder 20 are connected to be rotated.

In such a state, the hinge 30 is connected to the hinge cylinder 12 by inserting and installing the pusher stopper 40 between the set of guide ribs 13a provided in the assembly hole 13 of the first body housing 11. In the hinge knuckle 22, it is possible to maintain a more firmly coupled state.

Although the present invention has been described in detail using the preferred embodiments, the scope of the present invention is not limited to the specific embodiments, and should be interpreted by the appended claims. In addition, those skilled in the art should understand that many modifications and variations are possible without departing from the scope of the present invention.

According to the mobile communication terminal according to the present invention as described above, the hinge can be moved through the assembly hole formed in the rear of the first body housing to facilitate the coupling or detachment of the hinge, and also the push of the hinge inserted into the assembly hole By installing a rolling prevention device to prevent the damage, the assembly process and productivity of the terminal is improved, and since it does not require a separate cap member as in the prior art, it is possible to reduce the cost of the product by reducing the parts manufacturing cost. To provide.
