In this case, the first frame and the second frame are not defined but are different from any one of the structures to be fastened. For example, the first frame may be the front case 101, The case 102 may be used. Conversely, the first frame may be the rear case 102, and the second frame may be the front case 101. [ The combination of the first frame and the second frame is not limited thereto. For example, the first frame may be formed by stacking one or more frames, the second frame may be formed by a single frame, or both the first frame and the second frame may be formed by stacking a plurality of frames.

In one embodiment of the present invention, a frame provided with the fastening pin 136 will be referred to as a first frame, and a frame having a fixing member will be referred to as a second frame.

That is, the fastening pin 136 is formed on the first frame, the fastening member 139 is formed on the second frame, the first and second frames are formed to face each other, Respectively. At this time, the fastening member 130 may be one or more, and in the case of a mobile terminal, it may be formed near four corners, but the present invention is not limited thereto. For example, the fastening member 130 may be formed in a part of the inner region of the mobile terminal.

The fixing member 139 includes a housing 131 in which a first through hole 105a is formed at the center of the fixing member 139 so that the fixing pin 136 is received therein, A supporting member 133 for supporting the ball 132, an elastic member 134 for providing an elastic force to the supporting member 133, and at least one elastic member 134 for supporting the housing 131 Like cover 135 formed so as to cover one end of the plate-shaped cover 135.

The fixing member 139 is formed with a through hole into which the projecting portion 136a of the fastening pin 136 is inserted and the through hole is formed in the first through hole 105a and the center of the receiving member 133 And a third through hole 105c formed at the center of the cover 135. The second through hole 105b is formed in the center of the cover 135, The first to third through holes 105a, 105b and 105c are formed in series and have the same inner diameter (D, see FIG. 3). The ball 132 is seated in the receiving member 133 in the first state to push the ball 132 into the receiving groove 131a (see FIG. 2) in which the ball 132 is received, The ball 132 is moved on the receiving member receiving portion 137 in which the receiving member 133 is received in a state where the ball 132 is positioned on the receiving member 133. The receiving member receiving portion 137 is a hollow space having a larger diameter than the first through hole 105a in the housing 131.

The elastic member 134 may be a coil spring and a step 135a is formed on the upper surface of the cover 135 to fix the coil spring so as to be adjacent to the third through hole 105c . The elastic member 134 is positioned between the rim 133a and the step 135a so that the elastic member 134 is positioned between the rim 133a and the step 135a, And selectively presses the rim 133a to provide an elastic force to the receiving member 133. [ The rim 133a moves in contact with the inner surface of the receiving member receiving portion 137 to prevent the elastic member 134 from being detached from the fixed position.

2, the number of the balls 132 is three, but the present invention is not limited thereto. As shown in FIGS. 6A and 6B, the number of the balls 132 may be one or two, But it is not limited thereto and may be four or more. That is, at least one of the balls 132 is sufficient. In the case where one or two balls 132 are provided, the number of the receiving grooves 131a in which the balls 132 are accommodated is different, and the remaining part has the same structure as shown in FIG.

FIG. 3 is a schematic plan view of a fixing member 139 according to an embodiment of the present invention, illustrating the position of the ball 132 and the first through hole 105a. Referring to FIG. 3, when the number of the balls 132 is three, the balls are arranged at intervals of about 120 degrees with respect to the center of the first through hole 105a. At this time, when there are two balls 132, the balls are arranged at intervals of 180 degrees with respect to the center of the first through holes 105a. If there are four balls 132, It is preferable that they are arranged at intervals of 90 degrees with respect to the center.

In addition, in the first state, the ball 132 is formed to protrude into the first through-hole 105a to provide a frictional force to the fastening pin 136. In FIG. 3, the description is somewhat exaggerated for intuitive understanding. That is, the ball 132 is positioned inside the first through hole 105a. However, in the second state, the balls 132 are removed from the receiving groove 131a and moved to a position apart from the first through-hole 105a so as not to provide a frictional force to the connecting pin 136 . 4 shows the fixing member 139 in the second state and shows a state in which the supporting member 133 pushes up the ball 132 by the elastic member 134. As shown in Fig.

12A to 12F are views for explaining a fastening procedure of the fastening member 130 according to an embodiment of the present invention. 12A is a perspective view of the housing 131 viewed from the bottom. A first through hole 105a is formed in the housing 131, and a plurality of balls (not shown) are formed around the first through hole 105a. It is seen that the receiving groove 131a for receiving the receiving groove 132 is formed. At this time, the receiving groove 131a (more specifically, a seating portion 131c described later) is formed in the receiving groove 131a so that the ball 132 received in the receiving groove 131a protrudes into the inner region of the first through hole 105a. ) Is smaller than the diameter of the balls (132). 12B shows a state in which the ball 132 is received in the receiving groove 131a while the ball 132 is received in the housing 131. The ball 132 is received in the inner region of the first through hole 105a It can be seen that a part of the ball 132 is exposed.

12C shows a state in which the ball 132 and the receiving member 133 are accommodated in the housing 131. A second through hole 105b formed in the receiving member 133 is formed in the first through hole 105a. 12D shows a state in which a coil spring as an elastic member 134 is inserted in FIG. 12C. The elastic member 134 is in contact with the rim 133a of the receiving member 133. FIG. 12E shows a state in which the lower end of the housing 131 is covered with the cover 135. A third through hole 105c formed in the cover 135 is formed in the first through hole 105a, And is formed to communicate with the second through-hole 105b.

12F shows a state in which the protrusion 136a of the coupling pin 136 is inserted into the first through third through holes 105a, 105b, and 105c.

In the embodiment of the present invention, the fastening pins 136 are fixed and released by a magnetic force. For this purpose, the fixing members 139 are made of metal. For example, the ball 132 and the receiving member 133 may be formed of a metal material, and the connecting pin 136 may be made of a non-metallic material. If the engaging pin 136 is made of a metal material, when the magnetic member 145 is disposed under the cover 135, the engaging pin 136 is also attracted by the magnetic member 145, 136 is not easy to disassemble. However, the balls 132 are not necessarily made of a metal material. This is because when the supporting member 133 moves, the ball 132 moves to the receiving member receiving portion 137, which is a wider space than the receiving groove 131a. However, it is preferable to use a metal material to more reliably move the ball 132.

At this time, the support member 133 may be formed of a magnet, and the ball 132 may be formed of a non-metallic material. In this case, the magnetic member 145 disposed outside may have a polarity opposite to that of the receiving member 133. When the receiving member 133 is moved by attraction with the magnetic member 145, Is moved to the receiving member receiving portion 137.

5A to 5C are views for explaining the process of fastening and disengaging the fastening pin 136 to and from the fastening member 139 according to an embodiment of the present invention. 5A, when the projecting portion 136a of the fastening pin 136 is inserted through the through holes 105a, 105b, and 105c formed in the fixing member 139, the elastic force of the elastic member 134 The ball 132 is in close contact with the receiving groove 131a and if the connecting pin 136 is pulled out to pull out the connecting pin 136 by the frictional force between the ball 132 and the connecting pin 136, Is not pulled out. Particularly, the receiving groove 131a is inclined toward the drawing direction of the ball 132, so that the frictional force between the ball 132 and the protruding portion 136a becomes greater. That is, the receiving groove 131a includes an inclined portion 131b inclined toward the first through-hole 105a so as to move while the ball 132 is in contact with the inclined portion 131b, and an inclined portion 131b extending from the inclined portion 131b, And a seat part 131c. When the ball 132 is seated in the seating part 131c, the ball 132 is exposed toward the first through hole 105a.

5B, when the magnetic member 145 is disposed on one side of the cover 135, the ball 132 and the support member 133 made of a metal material are attracted by the magnetic force and descend. By this process, the ball 132 is released from the receiving groove 131a and is positioned in the receiving member receiving portion 137. [ In this state, the protrusions 136a of the balls 132 and the fastening pins 136 do not contact each other or contact with each other, so that no frictional force acts on the fastening pins 136, and the fastening pins 136 are easily released. 5B and 5C, when the magnetic member 145 is disposed on one side of the cover 135, the supporting member 133 is lowered down while pressing the elastic member 134, The balls 132 descend together to reduce the frictional force that the balls 132 provide to the fastening pins. When the fastening pin 136 is pulled in this state, the fastening pin 136 can easily be pulled out even with a small force, and the fastening pin 136 is pulled out through the through holes 105a, 105b and 105c. At this time, the receiving member receiving portion 137 provides a path for the receiving member 133 to move up and down, and in the second state, the ball 132 may be positioned. The upper surface of the receiving member 133 is formed so as to be inclined downward toward the outer side so that the ball 132 is positioned at the outer side of the receiving member receiving portion 137 in the second state, ). When the jig is removed, the supporting member 133 is returned to its original state by the elastic member 134.
