[0113] The body 1022 can be provided with openings in the printed circuit board 2 such that a portion of the core 102 is exposed on the first surface and a portion of the core 102 is exposed on the second surface. Furthermore, the body 102 forms an insertion port 1021 and a receiving space SP to accommodate the flexible circuit board 4. Here, the insertion port 1021 can also be chamfered 10218 to allow the flexible circuit board 4 to smoothly enter the insertion port 1021.

[0114] The multiple function parts 1024 are formed on both sides of the body 1022, where the side refers to the surface indicated in Figure 2(b).

[0115] The plurality of latching portions 1028 are formed on both sides of the accommodating space SP, where the side refers to the surface indicated in FIG2(c).

[0116] The plurality of first terminal slots 10210 are formed on a leading edge of the accommodating space SP (the side view referred to in FIG. 2(d)), and the plurality of second terminal slots 10212 are formed on a trailing edge of the accommodating space SP (the side view referred to in FIG. 2(c)). The first terminal slots 10210 and the second terminal slots 10212 can be staggered to reduce the volume of the recessed easy-lock and easy-unlock connector 10.

[0117] The plurality of stop portions 10214 are provided to protrude from the body 1022 to stop the rubber core 102 in the opening.

[0118] In another embodiment, the body 1022 further forms guide ribs 10216, 10216' to guide the adhesive core 102 to be disposed in the opening.

[0119] In another embodiment, the periphery of the body 1022 may also be formed with a chamfered structure. For example, the periphery of the body 1022 into the opening may be formed with a chamfered structure (not shown) to facilitate insertion into the opening.

[0120] Please refer to the above. Figures 3(a) to 3(b) Figure 1(a) and Figure 1(b) are perspective views illustrating the fasteners of the present invention from different angles. Figure 3(a) is a perspective view illustrating the fasteners of the present invention from Figure 1(a) and Figure 1(b), and Figure 3(b) is a perspective view illustrating the fasteners of the present invention from Figure 1(a) and Figure 1(b).

[0121] The fastener 104 includes a fastening block 1042, a connector 1044, a pressing member 1046, an elastic member 1048, and a base 10412.

[0127] The second terminal 1064 is disposed in the second terminal slot 10212. Here, the second terminal 1064 has the same structural design as the first terminal 1062. In other embodiments, the second terminal 1064 and the first terminal 1062 may also have different structural designs. Here, the second terminal 1064 further includes a second solder portion 10642, a second connecting portion 10644, a second bending portion 10646, and a second contact portion 10648. The second connecting portion 10644 connects the second bending portion 10646 and the second solder portion 10642. The second contact portion 10648 extends from the second bending portion 10646 to electrically connect to the flexible circuit board 4, and a second clearance structure 106410 is provided between the second solder portion 10642 and the second connecting portion 10644. In another embodiment, the second contact portion 10648 may further include at least one contact point protruding from the surface of the second contact portion 10648, which ensures that the second contact portion 10648 can be smoothly electrically connected to the flexible circuit board 4, especially when the flexible circuit board 4 has unevenness or other conditions that prevent smooth electrical connection.

[0128] As described above, the first clearance structure 106210 and the second clearance structure 106410 keep the first terminal 1062 and the second terminal 1064 away from the opening of the printed circuit board 2 by a certain distance, so as to avoid short circuits caused by conductivity with the metal layer (not shown) formed by the opening. Figure 5For example, the first connecting part 10624 and the first clearance structure 106210 are bent so that the first clearance structure 106210 is lower than the first connecting part 10624 on the same horizontal plane. The first clearance structure 106210 and the first welding part 10622 are also bent, so that the first clearance structure 106210 is lower than the first connecting part 10624 on the same horizontal plane. In other words, the first clearance structure 106210 is lower than both the first connecting part 10624 and the first welding part 10622. If we look at the perspective bottom view in Figure 1(b), the first clearance structure 106210 is higher than both the first connecting part 10624 and the first welding part 10622 on the same horizontal plane, so that the first terminal 1062 can avoid direct electrical contact with the metal layer located on the inner wall of the opening. Similarly, the description of the first terminal 1062 can also be applied to the second terminal 1064, such that the second clearance structure 106410 is lower than the second connecting portion 10644 and the second welding portion 10642.

[0129] Therefore, when the flexible circuit board 4 is inserted into the insertion port 1021, it can be seen in Figure 4(a), which is a side view showing the snap-fit ​​block 1042 of Figure 3(a) locking the snap-fit ​​hole of the flexible circuit board 4 in Figure 1(a). It can also be seen in Figure 4(b), which is a side view showing the snap-fit ​​block 1042 locking the snap-fit ​​hole of the flexible circuit board 4 in Figure 1(a) by the force generated by the sliding of the pressing member 1046 of the snap-fit ​​member 104 in Figure 3(a). Furthermore, Figure 4(b) shows that the pressing member 1046 is subjected to a vector force between the positive X-axis and the positive Y-axis, causing the pressing member 1046 to slide in an arc. When the operating portion 10244 below the pressing member 1046 is an inclined surface, the pressing member 1046 will slide along the operating direction OD of the inclined surface to achieve the purpose of sliding unlocking. It is worth noting that the surface height of the pressing member 1046 is not higher than the surface height of the body 1022. The surface of the body 1022 is exposed on the second surface to prevent accidental unlocking by touching the pressing member 1046.
