As shown, the interface device 12 can be firmly placed in place on the circuit board 11 by the interface device fixing mechanism 20 and the electrical connector 11b.

More specifically, the interface device fixing mechanism 20 includes a fixing component 100 and a rotatable fixture 200. The fixing part 100 may be made of any suitable metal or plastic. The fixing component 100 includes a main body 110 and a first engaging structure 120 connected to each other. The main body 110 has a mounting end 111 and an working end 112 located at the other end of the main body 110. The mounting end 111 may have a screw TS for screwing into any of the mounting holes MT of the board component 11a. The working end 112 has a working groove 1121. The working groove 1121 may be a slot or a cruciform slot into which a screwdriver (not shown) on the other side is inserted, and the fixing component 100 can be rotated so as to screw the mounting end 111 into the selected mounting hole MH. can.

Each of the hook portions 2213 has an inclined surface 2213a facing the opposite side to the positioning portion 2211. The first step for engaging the second engaging structure 221 with the first engaging structure 120 may be to fit the rotatable fixture 200 into the fixing part 100, with the inclined surface of the hook portion 2213. The 2213a first contacts the second locking surface 122 of the first engagement structure 120, and then the elastic portion 2212 is deformed by the increasing contact force, the hook portion 2213 moves outward, and the first engagement It may pass through structure 120. When the hook portion 2213 passes through the first engaging structure 120, the elastic portion 2212 returns the hook portion 2213 to its original position, and the hook portion 2213 engages with the first locking surface 121 of the first engaging structure 120. As a result, at least a part of the main body 110 is housed in the assembly part 220, the first engaging structure 120 is housed in the concave groove GV1, and the second locking surface 122 of the first engaging structure 120 faces the positioning part 2211. Then, the first engaging structure 120 and the second engaging structure 221 are engaged as necessary.

When the second engaging structure 221 is engaged with the first engaging structure 120, the assembly portion 220 cannot move in the axial direction and the radial direction. That is, the rotatable fixture 200 cannot be removed from the fixing component 100 unless a specific fixed amount of force is applied to pry open the hook portion 2213, but when the hook portion 2213 is removed, the hook portion 2213 and the elastic fixture 200 are elastic. Part 2212 may be damaged or even damaged. In other words, the assembly 220 of the rotatable fixture 200 is attached to the body 110 of the fixture 100 in a safe and reliable manner so that the rotatable fixture 200 is not lost.

As described above, the annular first engaging structure 120 is housed in the recessed groove GV1 formed between the positioning portion 2211 and the hook portion 2213, so that the assembly portion 220 rotates with respect to the main body 110. It is possible. In other embodiments, the second engagement structure may have one or more positioning portions and one or more hook portions, and accommodates the first engagement structure between them. One or more recesses may be formed for this purpose, and the assembly portion can be made rotatable with respect to the main body. In some other embodiments, the fixture may have a plurality of first engagement structures housed in a recess formed between the positioning portion and the hook portion, which is also an assembly. The part can be made rotatable with respect to the main body.

In this embodiment, the cylindrical body 110 is at least partially surrounded by the assembly 220, and the second engaging structure 221 engages the first engaging structure 120 from the outside. The present disclosure is not limited to the engagement method between the main body 110 and the assembly portion 220. In some other embodiments, the assembly is cylindrical, at least partially surrounded by the body, and the second engagement structure is from the inside of the first engagement structure to the first engagement structure. Engage with.

In the present embodiment, the inclined surface 2213a is configured to facilitate the hook portion 2213 to move on the first engaging structure 120. The inclined surface 2213a is arbitrary. In some other embodiments, the hook portion does not have to have an inclined surface.

In the present embodiment, the assembly portion 220 may further have a through hole OP on the support portion 210, the assembly portion 220, and the press portion 230. One end of the through hole OP near the assembly portion 220 is configured to insert the main body 110, and the other end of the through hole OP near the press portion 230 exposes the working groove 1121 to perform the above operation in the working groove 1121. It is configured to facilitate.

In this embodiment, the fixing component 100 may further include an adjacent portion 130. The adjacent portion 130 is arranged on the side surface of the main body 110 near the mounting end 111. As shown in FIG. 5, the adjacent portion 130 is placed on the substrate component 11a with the washer WS sandwiched between them. This configuration is for preventing the mounting end 111 from being excessively screwed into the board component 11a.

See FIGS. 7-9. Here, FIG. 7 is a cross-sectional view showing the interface device fixing mechanism of the electronic device shown in FIG. 5, and FIG. 8 is a partial top view showing that the press portion of the electronic device shown in FIG. 1 is not in the fixed position. 9 is a partial top view showing that the press portion of the electronic device shown in FIG. 1 has moved to the fastening position. The viewing angle of FIG. 7 is the same as that of FIG. The rotatable fixture 200 may further include a handle 240 extending outward from the press portion 230 for the operation of the rotatable fixture 200. The handle 240 is configured to be gripped by hand so that the user can rotate the assembly 220 with respect to the body 110 by operating the handle 240. The press portion 230 and the support portion 210 define a hold groove GV2 between them. The hold groove GV2 has an open end EN1 and a closed end EN2 arranged between the open end EN1 and the handle 240.

As shown in FIGS. 7 to 5 or 7 to 8, when the interface device fixing mechanism 20 is fixed to the board component 11a of the circuit board 11, the interface device 12 is formed with a hold groove GV2. It may be placed next to the missing support 210. Next, as shown in FIGS. 8 to 9, the handle 240 may be held, the assembly portion 220 may be rotated with respect to the main body 110, and the press portion 230 may be moved to the fastening position. When the press portion 230 is in the fastening position, the other end of the interface device 12 engages with the hold groove GV2 so that the interface device 12 is placed in place by the interface device fixing mechanism 20.

While moving the press portion 230 to the fastening position, the closed end EN2 can block and adjacent the end portion of the interface device 12 so as not to rotate the assembly portion 220 excessively. Further, as shown in FIG. 8, the direction D1 from the rotation axis of the rotatable fixture 200 to the closed end EN2 is at a first angle A1 with respect to the extension direction D2 of the handle 240. Thus, when the closed end EN2 is adjacent to the interface device 12, the handle 240 and the interface device 12 can be separated by a gap suitable for the finger, which the user grips and operates the handle 240 and presses 230. Is convenient to release the interface device 12 from the fastening position and release the interface device 12 from the interface device fixing mechanism 20. Further, as shown in FIG. 8, the direction D3 from the rotation axis of the rotatable fixture 200 to the open end EN1 is at a second angle A2 with respect to the extension direction D2 of the handle 240. The second angle A2 may be greater than 90 degrees. Therefore, when the press unit 230 is moved to the fastening position, the contact area between the press unit 230 and the interface device 12 is large enough to fix the interface device 12 to the interface device fixing mechanism 20.

Although the handle 240 is arranged on the press portion 230 along a direction perpendicular to the axis of rotation of the rotatable fixture 200, the shape of the handle 240 is not intended to limit the present disclosure. See FIG. FIG. 10 is an exploded view of the interface device fixing mechanism according to another embodiment of the present disclosure. It should be noted here that only the differences between this embodiment and the above embodiments will be described below. As shown in FIG. 10, the handle 240'is arranged next to the press portion 230' located away from the support portion 210' along the direction of the rotation axis of the rotatable fixture 200'. This configuration also allows the user to grab and operate the handle 240', rotate the press unit 230' to a fixed position, and operate the interface device (not shown in this embodiment) in a manner similar to that of the above embodiment. Convenient to fix.

According to the interface device fixing mechanism and electronic device described above, by engaging the second engaging structure with the first engaging structure, the rotatable fixture is non-removable from the fixing part. In other words, the assembly of the rotatable fixture is attached to the body of the fixture in a safe and reliable manner so that the rotatable fixture is not lost. In addition, the user can rotate the assembly of the rotatable fixture to release the interface device from the interface device locking mechanism.

In some embodiments, the rotatable fixture may further include a handle configured to be gripped by hand, so that the user can operate the handle to provide an assembly to the body. It can be rotated more conveniently. In addition, while moving the press to the fastening position, the closed ends can block and adjoin the ends of the interface device to prevent excessive rotation of the assembly. In addition, when the closed end touches the interface device, the handle and the interface device can be separated by a gap suitable for the finger, which allows the user to grasp and operate the handle and release the interface device from the interface device locking mechanism. It is convenient to release the press part from the fastening position. Further, the direction from the rotation axis of the rotatable fixture to the open end is an obtuse angle with respect to the extension direction of the handle, and as a result, between the press portion and the interface device when the press portion moves to the fastening position. The contact area of is large enough to secure the interface device on the interface device fixation mechanism.

This embodiment is selected and described to best explain the principles of the disclosure and its practical use, thereby allowing one of ordinary skill in the art to use the book with various modifications suitable for the particular application intended. Make disclosures and various embodiments best available. The scope of the present disclosure is intended to be defined by the following claims and their equivalents.
