The fastening groove 420 may include an insertion hole 421, a seating portion 423, and an insertion channel 422.

The insertion hole 421 may be an area of the fastening groove 420 into which the distal end 441 of the fastening pin 440 is inserted. The seating portion 423 uses a fastening pin 440 to respond to the tension generated in the binding member 430 when the binding member 430 is coupled to the wearable electronic device 400 and attached to the user's body. It may be a part that supports the distal end 441.

The insertion hole 421 and the seating portion 423 may be connected by an insertion passage 422. In some embodiments, the insertion passage 422 intersects the direction of tension generated in the fastening member 430 when the wearable electronic device 400 is fastened to the user's body by the fastening member 430. It may be connected to the seating portion 423 in a direction, for example, the z-axis direction of FIG. 4. Insertion passageway 422 may include at least one bend. Various shapes of the insertion passage 422 including the bent portion will be described later.

Referring to FIG. 6, the distal end 441 of the fastening pin 440 is inserted into the fastening groove 420 through the insertion hole 421 formed in the lug 410, moves through the insertion passage 422, and enters the seating portion. It may be located at (423). The fastening pin 440 receives the tension generated in the fastening member 430 when the wearable electronic device 400 is fastened to the user's body, and the seating portion 423 connects the fastening pin 440 with respect to the tension force. ) By supporting the distal end 441, the fastening pin 440 can be stably positioned on the seating portion 423. In some embodiments, the fastening passage may be connected to the seating portion 423 in a direction that intersects the direction of the tensile force (eg, -z direction). As the direction in which the fastening passage is connected to the seating portion 423 and the direction of the tensile force intersect, the risk of displacement of the fastening pin 440 due to changes in the magnitude and direction of the tensile force while wearing the wearable electronic device 400 is reduced. can do.

Figure 9d is a plan view showing a fastening pin 440 according to still other embodiments.

Referring to FIGS. 9A and 9B , the fastening groove 420 according to some embodiments may include a protruding locking protrusion 424 on the inner surface of the insertion passage 422. The locking protrusion 424 may be formed on an area of the insertion passage 422 adjacent to the seating portion 423. The locking protrusion 424 can reduce the risk of the fastening pin 440 located in the seating portion 423 coming out of the insertion passage 422.

Referring to FIG. 9A, the stopping protrusion 424 may be oriented in a direction to reduce the width (W, W') of the insertion passage 422. For example, the locking protrusion 424 may protrude on the lateral inner surface of the insertion passage 422. The fastening pin 440 located in the seating portion 423 can be prevented from being separated in the direction of the insertion passage 422 by the locking protrusion 424. In some embodiments, the locking protrusion 424 may be configured to have elasticity. In one embodiment, the stopper 424 may include a compressible elastic member (eg, spring). In another embodiment, the locking protrusion 424 may include an elastic material, such as an elastomer material such as NBR, silicone, TPU, FKM, or a mixture or copolymer thereof. Since the locking protrusion 424 has elasticity, when the fastening member 430 of the wearable electronic device 400 is mounted or replaced, the locking protrusion 424 is elastically deformed so that the fastening pin 440 is attached to the locking protrusion 424. ) can pass. In some embodiments, the lug 410 includes a slot 412 formed in an area where the locking protrusion 424 is located, and the locking protrusion 424 is made of an elastomer material injected into the slot 412 of the lug 410. It can be included. By injection molding the locking protrusion 424 into the slot 412, the fixing force of the locking protrusion 424 to the inner surface of the fastening groove 420 can be improved.

Referring to FIG. 9B , in other embodiments, the stopping protrusion 424 may be oriented in a direction to reduce the depths D and D' of the insertion passage 422. For example, the locking protrusion 424 may protrude on the bottom surface of the insertion passage 422. When mounting or replacing the fastening member 430 of the wearable electronic device 400, the fastening pin 440 can pass through the locking protrusion 424 by elastically reducing its length in the longitudinal direction. For example, the fastening pin 440 may be a spring bar including an elastic member, and the elastic member of the spring bar may be compressed to reduce the length of the spring bar so that it can pass through the stopping protrusion 424.

Referring to FIG. 9C , in other embodiments, the fastening pin 440 may be elastically bent and deformed in a direction perpendicular to the longitudinal direction of the fastening pin 440. The fastening pin 440 can pass through the locking protrusion 424 by reducing its longitudinal dimensions (L, L') due to elastic bending deformation. The integrally molded fastening pin 440 may pass through the stopping protrusion 424 by the above-described bending deformation. Since the fastening pin 440 may be bent and deformed, the monobloc fastening pin 440 may pass through the locking protrusion 424.

Referring to FIG. 9D , in still other embodiments, the fastening pin 440a is located at the central portion, for example, the thickness T' of the central portion 442a of the body portion 442 is equal to the thickness T of the peripheral portion of the central portion 442a. It may have a reduced shape compared to . As the fastening pin 440a has a shape with a reduced thickness in the central portion, for example, a concaved roller (or reverse-crowned roller) shape, elastic bending deformation of the fastening pin 440a becomes easy, and the range of deformation is can be increased. Accordingly, the fastening pin 440a is easily elastically bent and deformed, so that it can easily pass through the locking protrusion 424, and the elastic deformation range is increased, so the protrusion height H of the locking protrusion 424 can be increased. Therefore, The risk of the fastening pin 440a being separated from the seating portion 423 can be reduced.

The elastic material disposed in the area between the auxiliary fastening protrusions 432 moves in directions (e.g., y direction and -) in which the plurality of lugs 410 face each other when the fastening member 430 is rotated to be coupled to the lug 410. By being elastically deformed (e.g., compressed and/or bent) in the y direction), the auxiliary fastening protrusion 432 may pass through the edge of the lug 410 and be inserted into the auxiliary fastening groove 411 formed on the inside of the lug 410. .
