Specifically, the positioning fastener PF' may include: a main body casing 900, a guiding member 700 located in the main body casing 900, and an elastic member 800 located in the main body casing 900. In detail, according to the positioning component PF' of this embodiment, the bottom 920 of the main body shell 900 can be configured to buckle the engaging member 500 to clamp and hold the engaging member 500 . In addition, the main body shell 900 is further buckled on the guiding component 700 . The guide part 700 extends away from the space where the engaging member 500 is expected to engage and extends toward the top 910 of the main body casing 900, and has a body 720, and a body 720 facing away from the main body. The protruding portion 710 protrudes from the bottom 920 of the body shell 900 . In addition, the middle section of the main body shell 900 between the bottom 920 and the top 910 can have at least one side opening 905 , 915 , which can expose at least a part of the main body 720 . In addition, the top 910 of the main body casing 900 may have a top wall TP, and the top wall TP may have a top opening OP disposed corresponding to the protrusion 710 . For example, the top 910 of the main body housing 900 may have an annular top wall TP, and a circular top opening OP is defined by the annular top wall TP. The top opening OP can correspond to the protruding portion 710 of the guiding component 700 , and the protruding portion 710 can protrude or be received into the main body casing 900 through the top opening OP.

Based on the above, according to the present embodiment, the main body casing 900 can further be provided with an elastic member 800 , and the elastic member 800 can respectively abut against the top wall TP and the main body 720 to position the guiding member 700 .

In this aspect, the area of at least a portion of the body 720 parallel to the top opening OP may be greater than the area of the protrusion 710 parallel to the top opening OP, and thus the elastic member 800 wrapped around the protrusion 710 may abut at least an area of the body 720 A part and the top wall TP are used to position the guiding component 700 at a specific position or within a predetermined range through elasticity.

The above-mentioned guiding component 700 , elastic component 800 , or a combination thereof can be assembled with the main body casing 900 by processing and stamping, or directly using an over molding process (over molding) to inject a mold. However, the positioning fasteners according to other embodiments of the present invention may further have other components or other changes, and any suitable process may be used to complete the assembly. As above, the present invention is not limited thereto, and the above are examples only.

For example, the side openings 905 and 915 may face the sidewalls of the engaging groove oppositely, and thus expose at least a part of the body 720 of the guiding member 700 such as the guiding slope 725 corresponding to the sidewalls of the engaging groove. Based on the above, on a plane perpendicular to the height direction D3 of the guide member 700 along the bottom 920 of the main body housing 900 toward the top 910 of the main body housing 900 (for example, plane AR), from the bottom 920 of the main body housing 900 to the top 910 of the main body housing 900, guide Zhengbu The cross-sectional area of the member 700 gradually expands along the guiding slope 725 . Therefore, when the positioning fastener PF' that fastens the engaging member 500 passes through the above-mentioned engaging groove 600, the guiding slope 725 can slide along the engaging groove 600, and the guiding slope 725 can be used to Possible deformation and misalignment are corrected by the interactive movement of the two sides contacting and pressing the sidewall of the engaging groove 600 , thereby positioning the positioning fastener PF′ on the engaging hole 610 with a desired positioning accuracy. In this case, the part of the guiding member 700 including the guide slope 725 and above can function the same as or similar to the stopper portion 510 of the engaging member 500 of the various embodiments described above, and can be engaged with various types of engaging elements. The engagement state of the structures may be the same or similar to the engagement state of the stop portion 510 and the frame 300 in the foregoing embodiments, and will not be shown and described in detail here.

In some embodiments, the positioning fastener PF' may also cooperate with the above-described slope surface provided on the side wall of the engaging groove 600. For example, when the engaging groove 600 includes the entrance 630, the connecting groove 620 and the engaging hole 610 similar to the engaging structure M1, the entrance 630, the connecting groove 620 and the engaging hole 610 or a combination thereof are defined around the The sidewall may have a slope formed on the opposite surface S4 of the frame 300 facing away from the back plate 210 . Thereby, the guiding inclined surface 725 can slide on the inclined surface to guide the guiding component 700 to move from the initial state to the state of positioning and locking the frame 300 and the back plate 210 . In addition, similar guides are also applicable to other engaging structures, which will not be described in detail here.

Next, continue to refer to FIG. 19 , according to some embodiments of the present invention, in order to assist in positioning the locking member 500 and the guiding component 700 , the main body casing 900 may further have a first positioning protrusion 930 protruding toward the inside of the main body casing 900 . Based on the above, according to this embodiment, the first positioning protrusion 930 can restrict the movement of the guiding member 700 toward the bottom 920 of the main body casing 900 , and the first positioning protrusion 930 can restrict the direction of the engaging member 500 buckled by the main body casing 900 The top 910 of the main body housing 900 moves. That is, separated by the first positioning protrusion 930 , the guiding component 700 can avoid moving toward the bottom 920 of the main body casing 900 , and the engaging member 500 can avoid moving toward the top 910 of the main body casing 900 . Thereby, without direct contact between the guiding component 700 and the engaging component 500 , the engaging component 500 and the guiding component 700 can be fitted and fixed through the main body casing 900 .

In addition, as shown in FIG. 19 , the main body housing 900 may also have a second positioning protrusion 940 protruding toward the interior of the main body housing 900 relative to the first positioning protrusion 930 away from the top wall TP. Based on the above, the second positioning protrusion 940 can assist in restricting the engaging member 500 buckled by the main body shell 900 from moving toward the bottom 920 of the main body shell 900 . That is, the stop portion 510 of the engaging member 500 can be prevented from moving toward the bottom 920 of the main body casing 900 by being separated by the second positioning protrusion 940 . Further, the second positioning protrusion 940 may have a guiding slope SL', so that the length of the second positioning protrusion 940 protruding inward from the bottom 920 of the main body shell 900 toward the top 910 of the main body shell 900 increases gradually, or the The guiding slant SL′ faces toward the bottom 920 of the main body casing 900 . Thereby, the guide slope SL' can be configured to guide a part of the engaging member 500 (for example, the stopper portion 510 ) to slide between the first positioning protrusion 930 and the second positioning protrusion 940 , and be held by the first positioning protrusion. The block 930 and the second positioning protrusion 940 are constrained and clamped. Therefore, it is possible to reduce or avoid the unintended dislocation or falling off of the buckle 500 buckled by the main body shell 900, and increase the strength of the buckle buckle 500, thereby improving the fastening of the buckle 500 by positioning the buckle PF'. The stability and accuracy of the engaging and positioning corresponding to the engaging groove 600 .

Next, referring to Fig. 21A and Fig. 21B, when the main body casing 900 is fastened to the engaging member 500 as described above, and the upper part PF1 of the positioning fastener PF' protrudes from the frame 300 through the engaging hole 610, thereby engaging When the backplane 210 and the frame 300 are positioned in the second state A2, the top edge EP of the guide slope 725 can move upward relative to the main body casing 900 and away from the backplane 210 in the engaging hole 610 . In addition, since the frame 300 surrounds the side wall V1 defining the engaging hole 610, the side wall TP of the guide member 700 close to the main body casing 900 can be pushed through at least one side opening 905, 915, and the protrusion 710 can further protrude from the main body through the top opening OP. Shell 900.

According to some embodiments, in the second state A2, the protruding portion 710 can protrude from the main body casing 900 through the top opening OP to a second length L2, and the second length L2 in the second state A2 is greater than the second length L2 in the first state A1. A length L1. In detail, when the frame 300 and the backplane 210 are assembled by using the positioning fastener PF' to complete the assembly of the corresponding engaging member 500 and the engaging hole 610, due to the guide exposed through at least one side opening 905, 915 At least a part of the body 720 of the positive component 700 is pushed upward by the side wall of the engaging hole 610 , and the overall positive component 700 moves upward against the downward elastic force of the elastic component 800 . Therefore, the protruding portion 710 of the guiding member 700 can further protrude from the main body casing 900 through the top opening OP. Thereby, as shown in FIG. 21B , by observing whether the protruding portion 710 protrudes further from the main body casing 900 through the top opening OP, it can be judged whether the assembly and engagement are in place.

Based on the above, through the appearance change of the positioning fastener PF' moving from the position of the first state A1 to the position of the second state A2 after the assembly is completed (for example, according to the protruding portion 710 protruding from the main body shell 900 degree), can assist in judging whether the assembly of the frame 300 and the backplane 210 is completed, or whether the assembly positioning is performed correctly without misalignment. Therefore, it is possible to speed up the assembly process and improve the quality of assembly completion. finished product reliability. In this way, it is possible to reduce or avoid the time-consuming inspection work due to uncertain whether the assembly is completed, or to reduce or avoid the subsequent reverse engineering procedure or even the destruction procedure due to assembly defects. In addition, when rework is required, according to this embodiment, the difficulty of rework can also be reduced by the detachably assembled positioning fastener PF', which increases the convenience and yield of rework.
