Hereinafter, the operation of the switchgear having the above configuration will be described.

The coupling hole 332 of the second cam 330 is rotatably coupled to the coupling shaft 324 of the first cam 320 in a state in which the opening and closing device is assembled, and the first waveform of the first cam 320 is rotated. The surface 328 and the second waveform surface 336 of the second cam 330 are brought into close contact with each other so as to be rotatable in a sliding motion, and the first spring 340 bears behind the second cam 330. .

The coupling shaft 322 of the first cam 320 passes through the through hole 304 of the housing 300 and is fixedly coupled to the square hole 114 of the first direction rotation part 100. In addition, the sliding protrusion 338 of the second cam 330 is inserted into the sliding groove 308 of the housing 300 to prevent rotation.

When the second body 20 is closed to the first body 10, the valley of the peak of the first waveform surface 328 of the first cam 320 and the second waveform surface 336 of the second cam 330 And the valleys of the first waveform surface 328 remain combined with the acid of the second waveform surface 336.

On the other hand, between the first engaging jaw portion 420 and the first inclined projection 422 of the third cam 400, the second engaging jaw portion 450 and the second inclined projection 452 of the fourth cam 430 is Each is coupled, and the second spring 470 pushes the fourth cam 430 toward the third cam 400 to be in close contact with each other. As shown in FIG. 6, the first catching jaw 420 and the second catching jaw 450 are caught by each other to prevent the second body 20 from being rotated in the closed direction.

In this state, when the second body 20 starts to open, the second direction rotating part 200 and the first direction rotating part 100 rotate together with the second body 20. In this case, since the second cam inserted into the inner space of the housing 300 is fixed to the housing 300, the second cam 330 and the first cam 320 rotate while crossing each other, causing a sliding phenomenon.

When the second body 20 is opened to some extent from the first body 10, the mountain of the first waveform surface 328 slides and slides toward the mountain of the second waveform surface 336, so that the first spring 340 is moved. Is the most compressed state.

Subsequently, when the second body 20 is opened up to the call angle, the acid of the first waveform surface 328 is coupled to the valley beyond the acid of the second waveform surface 336, and the first spring 340 is extended to the restoring force. The second cam 330 is supported.

In this operation, the coupling hole 332 of the second cam 330 is inserted into the coupling shaft 324 of the first cam 320 to smoothly interact with the second cam 330 and the first cam 320. The center is firmly supported to make it happen. And the second cam 330 is a sliding protrusion 338 is inserted into the sliding groove 308 to prevent the rotational movement is only linear movement by the elasticity of the first spring 340.

In this state, the large LCD screen installed in the second body 20 faces the user side, and the camera installed in the same direction as the LCD screen faces the user's face. Therefore, the user operates the keypad to photograph his face.

On the other hand, when photographing a subject in front of the camera, it is necessary to rotate the second body 20 in the second rotation direction to reverse.

When the second body 20 is turned in the second rotation direction, the second direction rotation part 200 fixed to the second body 20 is rotated about the rotation axis 210.

In this process, as shown in FIG. 7, the second inclined protrusion 452 of the fourth cam 430 rotating together with the rotation shaft 210 rides over the first locking jaw portion 420 of the third cam 400. The second locking jaw portion 450 of the 4 cam 430 rides over the first inclined protrusion 422 of the third cam 400.

Subsequently, when the first body 10 is rotated 180 ° in the second rotation direction, as shown in FIG. 8, the first catching jaw 420 and the second catching jaw 450 are caught by each other again, so that the first body 10 is formed by the first body 10. It is prevented from opening any more in the open state in two rotation directions.

As described above, when the second body 20 is inverted, the large LCD screen faces outward. Therefore, when the camera of the first body 10 faces the front subject, the large LCD screen faces the user side. Therefore, the user can shoot the subject in front while viewing the large LCD screen.

As described above, when the second body 20 is closed in the first rotation direction in the state in which the second body 20 is opened in the second rotation direction, the acid of the first waveform surface 328 is formed in the second waveform surface 336. The first spring 340 is the most compressed state by sliding and moving to the mountain. Subsequently, when the second body 20 is completely closed, the acid of the first waveform surface 328 is coupled to the valley beyond the acid of the second waveform surface 336, and the first spring 340 is extended to the restoring force and the second The cam 330 is supported.

In this way, when the second body 20 is rotated in the first rotational direction and the first body 10 is closed, the LCD screen of the second body 20 is positioned on the upper surface, so that the user can turn off the communication terminal. You can see the LCD screen.

On the other hand, when the user does not see the large liquid crystal screen of the second body 20, the reverse operation is performed in the reverse order as described above to reverse the large liquid crystal screen of the second body 20 to face the first body 10 side. Close to the body (10).

As described above, in the rotary switchgear for communication terminal of the present invention, the signal line connecting the main body and the cover of the communication terminal is wired through the inside of the rotary switchgear, so that the appearance is clean and the signal line is contacted by external contact.
