Accordingly, when the push button 340 is pressed, the first protrusion 344 is moved downward, and the elastic member 350 is supported by the support protrusion 106b so that the push button 340 can be pressed upward. there is.

The second protrusion 246 is formed to extend further outward from the center of the push body 342 and downward from the push body 342 than the first protrusion 344 . The second protrusion 246 is fitted with a fixing ring 360 that can be hooked on the main body 102 so that the push button 340 does not come off.

Specifically, referring to FIG. 5C , the second protrusion 246 may pass through a through hole (not shown) formed in the push button groove 102b. Then, a fixing ring 360 is disposed around the second protrusion 246 in the lower portion of the through hole. The fixing ring 360 is formed to be larger than the diameter of the through hole. Accordingly, when the push button 340 is raised by the elastic member 350 surrounding the above-described first protrusion 344 , the fixing ring 360 arranged to surround the second protrusion 246 is the main body 102 . ), the push button 340 may be configured not to be separated from the main body 102 .

In summary, when the push button 340 is pressed, it may be returned to its original position by the elastic member 350 surrounding the first protrusion 344 . And, when the push button 340 is returned to its original position by the elastic member 350 , the push button 340 is attached to the main body 102 by the fixing ring 360 surrounding the second protrusion 246 . can be fixed.

Next, the locking member 310 is disposed in the insertion region where the strap 200 is inserted into the strap insertion groove 102a. In addition, the locking member 310 is inserted into the strap 200 and is configured to protrude to the outside of the strap 200 by the locking member spring 320 .

The mounting part 300 is inserted into the lower surface of the locking member 310 so that the locking member 310 is not separated from the strap 200 by the locking member spring 320, and the press-in pin 330 is engaged with the fixing protrusion 222a. ) may be further included.

Referring to FIG. 5A , the locking member insertion groove 212 may have a fixing protrusion 222a protruding into the groove. One end of the locking member spring 320 surrounding the locking member 310 is supported by the fixing protrusion 222a and the other end pushes the locking member 310 upward. Accordingly, the locking member 310 may move up and down within the locking member insertion groove 212 .

On the other hand, as shown in FIG. 5A , the locking member 310 includes a head 312 constituting the upper surface of the locking member 310 and a locking member extending downwardly to the lower portion of the head 312 to form a hollow groove in the center. It may include a leg portion 314 . A press-fitting pin 330 may be inserted into the hollow groove formed in the locking member leg portion 314 .

The press-in pin 330 may include a press-fit pin head 332 formed horizontally and a press-fit pin protrusion 334 that extends from the head and protrudes.

And, it may be supported so as not to be separated from the strap 200 by the press-in pin 330 disposed under the fixing protrusion 222a.

At least a portion of the push button groove 102b and the strap insertion groove 102a is formed with a communication hole that communicates with each other. Accordingly, when the strap 200 is coupled to the main body 102 , the upper end of the locking member 310 may come into contact with the lower end of the push button 340 through the communication hole. Specifically, as shown in FIG. 5A , when the locking member 310 inserted into the strap insertion groove 102a moves upward through the communication hole, it may come into contact with the push body 342 of the push button 340. .

On the other hand, the strap 200 is formed adjacent to the locking member insertion groove 212 in the

insertion regions

210a and 220a, and provides a space where the second protrusion 246 can be avoided when the push button 340 is pressed. An avoidance groove 214 may be formed. Specifically, as shown in FIGS. 3 and 5C , the avoiding groove 214 presses the upper surface of the strap 200 while the second protrusion 246 moves downward when the push button 340 is pressed. In order not to do so, it is possible to provide a space where the second protrusion 246 is avoided.

On the other hand, the locking member 310 has a first surface 312a that forms a corner on the far side from one end of the strap 200, and a second surface 312b that is tapered at an angle different from the first surface 312a. may include Specifically, as shown in FIG. 5A , the first surface 312a is disposed on the far side from one end of the strap 200 , and may constitute the rear surface of the upper surface of the locking member 310 . In addition, the second surface 312b may extend from the first surface 312a and be tapered at an angle greater than an angle formed by the first surface 312a. The first surface 312a may constitute the front surface of the locking member 310 .

Continuing to refer to FIG. 5A , in a state in which the strap 200 is fixed to the main body 102 , the first surface 312a of the locking member 310 is disposed in contact with the lower surface 342a of the push body. In this case, the push body flat surface 342b may be provided at an end of the push body lower end surface 342a and bent at an angle different from that of the push body lower end surface 342a. The push body flat surface 342b may be provided to prevent interference with the outer surface of the strap 200 while the push body 342 moves up and down.

6 and 7 are partial cross-sectional views for explaining a process of inserting and separating the strap 200 of the watch type terminal 100 into the main body 102 according to an embodiment of the present invention.

First, the direction is defined as follows. A direction (D1) in which the strap 200 enters the strap insertion groove (102a), a direction (D2) in which the strap 200 is separated from the strap insertion groove (102a), and the locking member 310 in the locking member insertion groove (212). ) and a direction D3 in which the locking member 310 descends in the locking member insertion groove 212 may be defined respectively. In addition, the push button 340 or the push body 342 may be defined as an ascending direction (Up) and the push body 342 in a descending direction (Down).

Specifically, as shown in (a) of Figure 6, the strap 200 may be inserted into the strap insertion groove (102a). The rear surface of the locking member 310 of the strap 200 protrudes as described above. Accordingly, as the strap 200 is inserted into the strap insertion groove 102a, the rear surface of the locking member head 312 may be pressed by the strap insertion groove upper end 106 .

6B, as the strap 200 enters the strap insertion groove 102a, the locking member head 312 is pressed by the strap insertion groove upper end 106, and the locking member insertion groove (212) is moved inward. At this time, as the locking member 310 moves, the user can feel the pressure between the locking member 310 and the strap insertion groove upper end 106 generated during the insertion process of the strap 200 .

Next, referring to FIG. 6C , as the strap 200 is completely inserted into the strap insertion groove 102a, the locking member 310 pressed by the upper end of the strap insertion groove 106 moves upward in the upward direction (D3). ) can be moved to Accordingly, the locking member 310 may push up the push body 342 in an upward direction (up).

As the locking member head 312 moves upward, the locking member head 312 is caught by the strap insertion groove upper end 106 . Accordingly, the strap 200 may maintain a coupled state without being separated from the main body 102 .

In addition, when the locking member 310 pressed by the upper end of the strap insertion groove 106 is moved in the upper direction D3, the locking member head 312 is moved by the elastic force of the locking member spring 320, While the locking member head 312 is moved, a clicking sound may be generated and a physical vibration may occur at the same time. Accordingly, there is an advantage that the user can know that the strap 200 is completely coupled to the main body 102 .

On the other hand, in the process in which the strap 200 is separated from the strap insertion groove 102a, the locking member 310 is moved to the first surface 312a by the push button 340 in the process in which the locking member 310 is moved up and down. When this is pressed, the locking member 310 is moved to the inside of the strap 200 and the strap 200 is moved in a direction to be separated from the strap insertion groove 102a by the push button 340 on the second surface. (312b) can be made to be pressurized.

Specifically, referring to FIG. 7A , the upper end of the push body 342 is pressed to separate the strap 200 from the main body 102 . Referring to FIG. 7B , as the push body 342 moves downward, the locking member spring 320 is compressed and the locking member 310 moves downward.

At this time, as described above, the first surface 312a and the second surface 312b constituting the upper surface of the locking member 310 form an inclination with respect to the outer peripheral surface of the strap 200 . Accordingly, when the push button 340 presses the upper end of the locking member 310, the locking member 310 is formed on an inclined surface formed by the first surface 312a and the second surface 312b. By being pressed, a force to be separated from the strap insertion groove 102a may be generated.

Then, referring to FIG. 7C , the push button 340 presses the second surface 312b of the locking member head 312 . As described above, the second surface 312b of the locking member head portion 312 is an inclined surface having a steeper angle than the first surface 312a. Accordingly, the locking member 310 may receive more force to be separated from the strap insertion groove 102a.

That is, as the push button 340 presses the locking member head 312 , it presses the first surface 312a of the locking member head 312 at the initial stage of pressing. And, when the locking member head 312 is pressed by the strap insertion groove upper end 106 while the strap 200 is detached from the strap insertion groove 102a, the push button 340 becomes the locking member head portion ( The second surface 312b of the 312 is pressed. Since the second surface 312b is formed to be more inclined than the first surface 312a, as the second surface 312b is pressed, a force is generated in the direction in which the locking member 310 is released from the strap insertion groove 102a. . Accordingly, the locking member 310 and the strap 200 can be separated from the strap insertion groove 102a more easily and quickly.

Referring to (d) of Figure 7, the strap 200 is separated from the strap insertion groove (102a) by the above-described mechanism.

In the watch type terminal 100 according to an embodiment of the present invention, the locking member head portion 312 is formed with a first surface 312a and a second surface 312b having a larger inclination than the first surface 312a. is done Although the push button 340 or the push body 342 presses the first surface 312a in the initial release of the strap 200, the locking member 310 is compressed and the locking member head part 312 in the process of release occurs. By pressing the second surface 312b, the locking member 310 may receive a force in a direction in which it is separated. Accordingly, there is an advantage that the release of the strap 200 can occur more easily.

8 is a conceptual diagram for explaining the angular relationship between the strap insertion groove 102a, the main body 102, and the mounting unit 300 of the watch type terminal 100 according to an embodiment of the present invention.

Referring to FIG. 8 , the upper surface 106 and the lower surface of the insertion groove of the strap 200 and the lower surface 342a of the push body may be parallel to each other. That is, in the cross section shown in FIG. 8 , the axis a1 formed by the strap insertion groove 102a, the axis a2 formed by the upper surface 106 of the strap 200 insertion groove, and the lower surface of the strap insertion groove 102a The angle of the axis a3 formed by this may be the same. Also, the axis a4 formed by the lower end surface 342a of the push body may have the same angle.

In addition, the second surface 312b of the locking member head 312 has an axis b between the push body lower end surface 342a and the second surface 312b of the locking member 310 to form a predetermined angle. can For example, an angle between the lower end surface 342a of the push body and the second surface 312b of the locking member 310 may be 15 to 30 degrees.

According to an embodiment of the present invention, the locking member head 312 forms the first surface 312a and the second surface 312b, and the second surface 312b is inclined. In addition, the inclination formed by the second surface 312b may form a predetermined angle with the push button 340 or the lower end surface 342a of the push body.

Accordingly, while the strap 200 is released from the main body 102 , the push body 342 initially presses the first surface 312a of the locking member head part 312 , but the strap 200 is the main body 102 . In the process of being physically separated from the body 102 , the lower end surface 342a of the push body may press the second surface 312b of the locking member head 312 . That is, the locking member head portion 312 includes a first surface 312a and a second surface 312b, and the second surface 312b forms a larger angle than the first surface 312a, and the second surface ( 312b) forms a predetermined angle with the lower end surface of the push body 342a, so that the push body 342 presses the first surface 312a in the process of releasing and detaching the locking member 310 and the second surface 312b ) can be pressurized.

Accordingly, there is an advantage that the strap 200 can be more easily separated from the main body 102 while the strap 200 is separated from the main body 102 .

The above detailed description should not be construed as restrictive in all respects and should be considered as exemplary. The scope of the present invention should be determined by a reasonable interpretation of the appended claims, and all modifications within the equivalent scope of the present invention are included in the scope of the present invention.
