Description

TECHNICAL FIELD

[0001] The present application relates to a fixing device, in particular, a fixing device for electronic devices, such as M.2 solid state drive, Wi-Fi wireless network card, 3G network card or circuit board. BACKGROUND

[0002] An electronic device, such as M.2 solid state drive, has a plug-in portion with a plurality of contact terminals at one end and a semicircular positioning groove for positioning at the other end. The plug-in portion is plugged into a default connector on a board, such as a printed circuit board, and the positioning groove at the other end is clamped in a fixing device. The fixing device includes a positioning member plugged into the board, which has a cylindrical body with an axially extending plug-in hole. The top surface of the cylindrical body is provided with a supporting recess for mounting the positioning groove of the electronic device. The fixing device also includes a clamping member with a clamping piece. The top surface of the clamping piece axially extends a fixing pin inserted into the plug-in hole. The clamping piece closes the supporting recess and clamps the positioning groove together with the supporting recess, so that the electronic device can be fixed to the board and electrically connected to the connector.

[0003] The fixing pin is provided with a positioning buckle groove, and the plug-in hole is correspondingly provided with a positioning convex ring at the position corresponding to the positioning buckle groove. When the fixing pin is inserted into the plug-in hole, the positioning buckle groove interferes with the positioning convex ring to achieve the fixing effect of the clamping member clamped to the positioning member. However, the above clamping structure is repeatedly inserted and pulled out, which causes the positioning buckle groove and the positioning convex ring to be worn, thereby reducing the holding force during fixing. Even after multiple uses, the fixing effect is lost due to the lack of interference function, so improvement is needed. SUMMARY

[0004] The main purpose of the present application is to provide a fixing device for electronic devices, which uses a rotating member to rotate and position on a positioning member. A stop wing of the rotating member forms at least a partial shielding effect on a supporting recess of the positioning member, so as to form a locked state for an electronic device, such as M.2 solid state drive, Wi-Fi wireless network card, 3G network card or circuit board.

[0006] In an embodiment, the support recess is for the cross placement of a positioning recess of an electronic device, and the outer circumferential surface of the step adjacent to the support recess forms a positioning protrusion for the positioning of the positioning recess; and the pair of stop flanges abut against a bottom wall on both sides of the positioning recess of the electronic device, so as to provide an anti-rotation function for the electronic device.

[0007] In an embodiment, the outer circumferential surface between the starting notch and the terminal notch further has at least one relay notch for the selective engagement of the tenon.

[0008] In an embodiment, the fixing structure comprises an arrow-shaped fixing hook protruding from the bottom of the body, the fixing hook outwardly extending a pair of elastic hook pieces, and the free ends of the pair of elastic hook pieces oppositely having a plurality of tooth steps arranged in a stepped manner, so as to be engaged in a plate hole of different thickness or different aperture.

[0009] In an embodiment, at least one outer surface of the fixing hook axially protrudes an auxiliary fixing rib capable of increasing the engagement with the plate hole.

[0058] As Figure 1 and Figure 2As shown, it shows a fixing device for an electronic device (such as M.2 solid state disk, Wi-Fi wireless network card, 3G network card or circuit board) in the embodiment one of the present application, the fixing device is a solid object formed by injection molding processing of insulating material (such as plastic), the fixing device includes a positioning member 1 and a rotating member 2.

[0059] The positioning member 1 has a geometric shape, such as a circular body 11, the top surface of the body 11 is provided with a convex step 12, the step 12 is axially provided with a plug-in hole 13, and a pair of stop flanges 121 is radially provided on the outer circumferential surface of the step 12, one side between the pair of stop flanges 121 forms a supporting recess 122, and the other side opposite to the one side forms a rail groove 123. Wherein the supporting recess 122 is used for crossing the positioning recess hole 42 (shown in Figure 9 ) of the electronic device 4 (such as M.2 solid state disk), and the outer circumferential surface of the step 12 adjacent to the supporting recess 122 forms a positioning protrusion 124 for positioning the positioning recess hole 42. And the pair of stop flanges 121 abuts against the bottom wall on both sides of the positioning recess hole 42 of the electronic device 4, so as to provide anti-rotation function for the electronic device 4.

[0060] The outer circumferential surface of the step 12 adjacent to the rail groove 123 and the two ends of the rail groove 123 respectively form a starting card slot 125 and a terminal card slot 126. In addition, at least one relay card slot 127 is also provided on the outer circumferential surface between the starting card slot 125 and the terminal card slot 126.

[0061] In order to enable the positioning member 1 to be fixed to a plate 3 (please refer to Figure 8 and Figure 9 ), in addition, the bottom surface of the body 11 also includes a fixing structure 14 capable of being fixed to the plate 3, please refer to Figures 1 to 4 , the fixing structure 14 includes an arrow-shaped fixing hook 141 protruding from the bottom of the body 11, the fixing hook 141 extends outwardly a pair of elastic hook pieces 142, the free ends of the pair of elastic hook pieces 142 are oppositely provided with a plurality of tooth steps 143 arranged in a stepped manner, so as to be buckled in the plate hole 31 of different thicknesses or different hole diameters, so as to expand the use range. Wherein, the outer surface of the fixing hook 141 is protrudingly provided with a fixing protrusion 144, the fixing hook 141 and the fixing protrusion 144 can be plugged into the T-shaped plate hole 31 (please refer to Figure 8 ), and the fixing protrusion 144 provides the anti-fumble (anti-misplug) effect.

[0062] Further, an outer surface of the fixing hook 141 and / or a surface of the fixing hook 141 axially opposite to the outer surface is axially protruded with an auxiliary fixing rib 145. The auxiliary fixing rib 145 can adapt to the tolerance of the plate hole 31 and increase the engagement with the plate hole 31 by the plastic elastic deformation of the auxiliary fixing rib 145 itself, thereby enhancing the fixing effect.

[0063] The rotating member 2 radially has a blocking wing 21. An under surface of the blocking wing 21 is axially protruded with a clamping tongue 211 (see Figure 2 ) located in the track groove 123. The rotating member 2 also has a rotating shaft 22 inserted in the insertion hole 13. An outer circumferential surface of the rotating shaft 22 is correspondingly provided with an anti-disengagement structure, such as at least one hook 221 and an annular clamping groove 131 (shown in Figure 13 ) on an inner circumferential surface of the insertion hole 13. Figure 1 Figure 2 As shown in

[0064] In addition, a top surface of the blocking wing 21 is axially protruded with a holding piece 23 for a user to hold. When the holding piece 23 is rotated, the blocking wing 21 and the rotating shaft 22 can be synchronously rotated.

[0065] Therefore, during the process of inserting the rotating shaft 22 into the insertion hole 13, the at least one hook 221 can enter the annular clamping groove 131 along the corresponding pair of guide inclined surfaces 132, so that the at least one hook 221 is stopped by the upper edge of the annular clamping groove 131 after elastic recovery, and the rotating member 2 cannot be axially disengaged from the positioning member 1.

[0066] Therefore, when the holding piece 23 is rotated, the blocking wing 21 and the rotating shaft 22 are synchronously rotated, and the clamping tongue 211 is selectively clamped in the terminal clamping groove 126, the intermediate clamping groove 127 or the starting clamping groove 125, and whether the blocking wing 21 shields the supporting recess 122 or not, so as to determine the locking or unlocking state of the electronic device 4 (see Figures 9 to 11 ). If in the locking state, at least a part of the blocking wing 21 and the supporting recess 122 can jointly clamp the positioning recess hole 42 of the electronic device 4, so that the electronic device 4 is stably positioned and cannot be shaken.

From Figure 3 It can be clearly seen that the baffle 21 is a semi-circular fan-shaped piece, and the baffle 21 does not completely cover the support recess 122. Furthermore, from... Figure 5 As can be clearly seen, the latch 211 is positioned in the starting slot 125, preventing the rotating part 2 from rotating due to vibration.

[0068] Please see Figure 6 It shows a top view of the rotating member 2 rotated relative to the positioning member 1 at an angle, and shows that the retainer is in a locked state over the electronic device 4. From Figure 6 It can be clearly seen that the baffle 21 partially covers the support recess 122, and the latch 211 is positioned in the relay slot 127, thus preventing the rotating part 2 from rotating due to vibration.

[0069] Please see Figure 4 and Figure 7 It shows a perspective view and a top view of the rotating member 2 rotated relative to the positioning member 1 to another angle, and shows the retainer in a locked state over the electronic device 4. From Figure 4 It can be clearly seen that the baffle 21 partially covers the support recess 122. Furthermore, from... Figure 7 It can be clearly seen that the latch 211 is positioned in the terminal slot 126, which also prevents the rotating part 2 from rotating due to vibration.

In this embodiment, the plate 3 is a circuit board, and the electronic device 4 is selected from the circuit boards of a Wi-Fi wireless network card, a 3G network card, or an M.2 solid-state drive. During assembly, the assembly personnel first align the fixing hook 141 and the pair of elastic hook pieces 142 of the fixing structure 14 of the positioning component 1 with a T-shaped hole 31 in the plate 3 and insert it (shown in...). Figure 8 The pair of teeth 143 of the elastic hooks 142 are engaged with the long edge of the plate hole 31, and the fixing protrusion 144 is engaged with a short edge of the plate hole 31 to prevent the positioning member 1 from being installed incorrectly. The fixing structure 14 is used to securely install the positioning member 1 onto the plate 3 (shown in the figure). Figure 9 ).

[0071] Next, a contact portion 41 at one end of the electronic device 4 is inserted into a connector 32 on the plate 3; and a positioning recess 42 at the other end is lowered and placed into the support recess 122 (shown in...). Figure 10 andFigure 12 At this time, the assemblers rotate the holding piece 23 in a counterclockwise direction, so that the blocking wing 21 and the tenon 211 thereof and the rotating shaft and the at least one hook 221 thereof rotate synchronously, thus making the at least one hook 221 rotate in the annular hook groove 131 of the insertion hole 13, and making the tenon 211 disengage from the initial card groove 125 and pass through the relay card groove 127 until reaching a stop flange 121 and being buckled into the terminal card groove 126, so that the blocking wing 21 partially shields the supporting recess 122 and clamps the other end of the electronic device 4 together with the supporting recess 122, so as to lock the electronic device 4 (shown in Figure 11 and Figure 13 ), and the positioning member 1 is fixed to the board 3, so that the electronic device 4 can be positioned stably, and can ensure the electrical connection between the electronic device and the connector 32.

[0072] As shown in Figures 14 to 15 , which shows the fixer in the second embodiment of the present application, the same reference numerals (symbols) in the second embodiment and the first embodiment are used to represent the same components, since the second embodiment has many same components as the first embodiment, and thus only the differences between the two embodiments will be described in detail below.

[0073] In the second embodiment, a surface of the fixing hook 141 is not provided with the fixing protrusion 144 in the first embodiment, and thus a board hole 31 of the board 3 for the insertion of the fixing structure 14 is not foolproof designed.

[0074] Therefore, in the second embodiment, at least one outer surface of the fixing hook is axially protruded with an auxiliary fixing rib 145, the auxiliary fixing rib 145 can adapt to the tolerance of the board hole 31, and the engagement with the board hole 31 can be increased by the plastic elastic deformation of the auxiliary fixing rib 145 itself, so as to enhance the fixing effect.

[0075] Therefore, the fixer for electronic device provided in the embodiments of the present application has the following beneficial effects: the rotating shaft of the rotating member is inserted into the insertion hole of the positioning member, so that the rotating member has the function of rotating relative to the positioning member, and the tenon selectively buckles into the terminal card groove or the initial card groove, and the blocking wing shields or does not shield the supporting recess, so as to lock or unlock the electronic device. Compared with the prior art, the structure in the present application has significant advantages.
