As shown, the mobile terminal case 200 includes a case body formed to surround the mobile terminal 100 and a strap 300 integrally coupled to the outer surface of the case body.

The case body may be manufactured in other forms according to the design of the mobile terminal 100 or the taste of the user. According to the illustrated embodiment, the case body is formed to surround the side surface 210 and the rear surface of the mobile terminal 100. An image module hole 221 and an input module hole 222 are formed on one surface of the case body to correspond to the image module and the input module mounted on the rear of the mobile terminal 100.

The side surface 210 of the case body has a seating groove 211 in which the strap 300 is seated. As shown, the seating groove 211 is formed to surround the entire case body side 210.

The fixing protrusion 230 is formed on the body. The fixing protrusion 230 includes a hole 231 formed to pass through the strap 300. That is, the hole 231 is formed in the direction in which the seating groove 211 extends.

The strap 300 is formed to surround the side 210 of the case body, and according to a preferred embodiment the length of the strap 300 is formed to be equal to the circumferential length of the case body side 210. That is, the strap 300 is integrally coupled to the case body to form the appearance of the case. Strap 300 is usually disposed in a state seated in the seating groove 211, can be used as a ring pulled out from the seating groove 211 when necessary.

According to the exemplary embodiment of the present invention, the size of the hole 231 formed in the fixing protrusion 230 is smaller than the thickness of the strap 300. Strap 300 is made of an elastic member that can extend in the longitudinal direction, such as rubber. When the force is applied to the strap 300 in the longitudinal direction and inserted into the hole 231, and the force is removed, the strap 300 is strongly engaged with the hole 231 by a restoring force. That is, unless the strap 300 is intentionally pulled, the strap 300 is not separated from the fixing protrusion 230.

That is, according to the present embodiment, the mobile terminal 100 having a curved surface may be seated on the case body.

One end of the side surface 210 may have a protrusion 212 protruding in the width direction of the terminal. The protrusion 212 prevents the mobile terminal 100 from being arbitrarily separated after being seated in the case. When the mobile terminal 100 is to be separated from the case, the case body side 210 is pulled laterally and the mobile terminal 100 is taken out of the case. That is, in the state in which the mobile terminal 100 is seated on the case, the protrusion 212 is caught on the front surface of the mobile terminal 100 to prevent the mobile terminal 100 from being arbitrarily separated. The case body is formed to have elasticity to protect the mobile terminal 100 from external impact. When the body side 210 is pulled in the lateral direction, the side surface 210 of the body is elastically deformed so that the projections caught by the mobile terminal 100 are spaced apart from the mobile terminal 100. After that, the mobile terminal 100 is separated from the case by giving a force toward the case front.

The hole may form part of the seating groove 211. In other words, the strap 300 is seated in the seating groove 211 and is formed such that the fixing protrusion 230 surrounds the seated strap 300. The space surrounded by the fixing protrusion 230 has been described as a hole for convenience.

According to one embodiment of the invention, the hole may be formed smaller than the thickness of the strap (300). The strap 300 is formed of a material that is elastically deformed, such as rubber, and is elastically deformed to engage the hole 231. For example, the shape of the strap 300 before it is elastically deformed is shown in dashed lines. The strap 300 is formed to be a little thicker than the size of the hole 231 and elastically deformed when inserted into the hole 231 to be engaged with the hole 231.

One end of the case body may have a protrusion 212 protruding in the longitudinal direction of the terminal. The protrusion 212 prevents the mobile terminal 100 from being arbitrarily separated after being seated in the case. When the mobile terminal 100 is to be separated from the case, the case body lower surface 210 is pulled downward and the mobile terminal 100 is taken out of the case. That is, in the state in which the mobile terminal 100 is seated on the case, the protrusion is caught on the front surface of the mobile terminal 100 to prevent the mobile terminal 100 from being arbitrarily separated. The case body is formed to have elasticity to protect the mobile terminal 100 from external impact. When the lower body 210 is pulled downward, the lower surface 210 of the body is elastically deformed so that the projections caught by the mobile terminal 100 are spaced apart from the mobile terminal 100. Thereafter, the mobile terminal 100 can be separated from the case by applying force to the case front direction.
