FIG. 12 is a view showing a cover member constituting a mobile terminal according to an embodiment of the present invention, FIG. 13 is a view showing a rear case constituting a mobile terminal according to an embodiment of the present invention, Sectional view of a protrusion and a groove of a mobile terminal according to an embodiment of the present invention.

10 and 11 illustrate the protrusion 210 and the groove 103 having a polygonal cross section as an example but the present invention is not limited thereto and may have a circular or elliptical cross section or may have a protrusion 220 and a groove 106 may be a curved surface having a predetermined curvature.

12 to 14, the protrusion 220 of the cover member 200 includes a main body (not shown) extending along the longitudinal direction and a first contact surface 226 provided on one side of the main body, The first contact surface 226 may have an inclination degree &thetas; reduced along the mounting direction, and the end thereof may have an inclination of 0 DEG with respect to the main body (not shown).

In addition, the body may have a circular or elliptical cross section.

12, the protrusion 220 may have a tip portion 224 of the first contact surface 226 having a predetermined angle of inclination along the mounting direction A, and the inclination of the tip portion 224 may be gradually decreased, (Substantially parallel) with respect to the main body or the cover member 200 at an angle of 0 [deg.].

13, the groove 106 of the rear case 102 is provided with a recess (not shown) in which the main body is accommodated, and a groove (not shown) provided on one side of the recess, 2 contact surfaces 109,

Also, the inclination degree of the second contact surface 109 may be decreased along the mounting direction, and the end of the second contact surface 109 may have an inclination of 0 ° with respect to the rear case 102.

Concretely, the groove 106 may have an inclination corresponding to the tip end portion 224 of the first contact surface 226 along the mounting direction, and the inclination degree is decreased in turn The distal end 108 may have a 0 degree inclination corresponding to the distal end 225 of the first contact surface 226. [

The tip end portion 224 of the first contact surface 226 of the protrusion 220 of the cover member 200 and the tip end portion 107 of the second contact surface 109 of the groove 106 may have a structure in which the inclined surfaces are in contact with each other, The distal end portion 225 of the first contact surface 226 and the distal end portion 108 of the second contact surface 109 are in plane contact with each other.

According to such a structure, even when the cover member 200 is deformed due to repeated attachment / detachment because the protrusion 220 and the groove 106 are flatly coupled to each other in a partial area, after the coupling with the rear case 102 A constant gap can be maintained, and the dimension management becomes easy. Further, since it has a planar coupling structure after the inclined surfaces are coupled along the mounting direction, it is easy to attach and detach.

Hereinafter, a bar-type mobile terminal 100 has been described as an example. Hereinafter, a mobile terminal will be described as a slide type, a folder type, or a swivel type.

A mobile terminal according to another embodiment of the present invention may include a first body having a control unit and a power supply unit, and a second body mounted with respect to the first body and having a display unit.

Here, the second body may be mounted to be slidable, folded, or swivelable relative to the first body.

The first body may include a rear case accommodating a portion of the power supply unit and a cover member surrounding the power supply unit and mounted to the rear case. The cover member and the rear case may have inclination angles Respectively.

The present embodiment differs from the mobile terminal 100 in that the mobile terminal 100 is not a bar type mobile terminal but a slide type, a folder type or a swivel type mobile terminal. The front case, the rear case, The cover member is the same as the front case, the rear case and the cover member of the mobile terminal 100 described above.

The mobile terminal described above can be applied to not only the configuration and method of the embodiments described above but also all or some of the embodiments may be selectively combined so that various modifications may be made to the embodiments It is possible.
