Detailed Description

In order that the objects, technical solutions and advantages of the present invention will become more apparent, the present invention will be further described in detail with reference to the accompanying drawings in conjunction with the following specific embodiments.

Referring to fig. 3 to 6, a first embodiment of a holder 1 for an electronic device 30, such as an m.2 solid state drive, a Wi-Fi wireless network card, a 3G network card or a circuit board, is disclosed, the holder 1 comprising a body 11 injection molded with an insulating material, such as plastic.

In order to fix the fixer 1 to a plate 20 (refer to fig. 9 to 13), the middle section of the main body 11 further includes a plate fixing structure 12 fixed to the plate 20, and the plate fixing structure 12 includes at least one groove 121 radially opened from an outer circumferential surface of the main body 11. As shown in fig. 3, a pair of grooves 121 is radially opened on the outer peripheral surface of the body 11, and a locking groove 122 of a fastening structure is axially opened in each groove 121. The plate has a plate hole 205 with a keyhole shape, the plate hole 205 includes a through hole 205a for the body 11 to pass through, and a connecting groove 205b communicating with the through hole 205a and for the pair of grooves 121 to be sleeved, and a fastening tenon 205c of the fastening structure is disposed in the connecting groove 205b corresponding to each fastening groove 122, so that the body 11 can be fixed in the plate hole 205 by the plate fixing structure 12 without sliding or shifting.

In another embodiment, the tenon of the fastening structure is disposed in each of the grooves 121, and the slot is disposed at a corresponding position in the slot 205 b.

The top and bottom of the body 11 include a pair of locking structures 13 for fixing an end of each of the two electronic devices 30 and configured as mirror images, and each of the locking structures 13 includes a positioning portion 131 and a rotating portion 132.

For convenience of describing the pair of locking structures 13, only the top locking structure 13 is described in detail, the positioning portion 131 has a raised step 131a, the step 131a is axially provided with an insertion hole 131b, a pair of stopping flanges 131c are radially provided on an outer circumferential surface of the step 131a, a supporting recess 131d is formed on one side between the stopping flanges 131c, and a rail groove 131e is formed on the other opposite side. The supporting recess 131d is used for a positioning groove 302 (shown in fig. 13) of the electronic device 30, such as an m.2 solid state disk, to straddle, and the step 131a is adjacent to the outer peripheral surface of the supporting recess 131d to form a positioning protrusion 131f for positioning the positioning groove 302. The pair of stop flanges 131c abut against a bottom wall of the electronic device on both sides of the positioning groove 302, so as to provide an anti-rotation function for the electronic device 30.

The step 131a is adjacent to the outer circumferential surface of the rail groove 131e and forms a start catch groove 131g and a finish catch groove 131h with both ends of the rail groove 131e, respectively.

The rotating portion 132 has a blocking wing 132a in a radial direction, a tenon 132b (please refer to fig. 5 and 6) located in the rail groove 131e is axially protruded from a bottom surface of the blocking wing 132a, and a rotating shaft 132c inserted into the insertion hole 131b, and an anti-disengaging structure, such as at least one hook 132d and an annular groove 131i (shown in fig. 17), is correspondingly disposed on an outer circumferential surface of the rotating shaft 132c and an inner circumferential surface of the adjacent insertion hole 131 b. As shown in fig. 4 to 6, the at least one hook 132d is a pair and is disposed opposite to the outer peripheral surface of the rotating shaft 132 c. The top of the inserting hole 131b is formed with a guiding inclined surface 131j corresponding to the position of each hook 132d, so that the pair of hooks 132d can move along the corresponding pair of guiding inclined surfaces 131j, and can smoothly enter the annular groove 131i through the plastic elastic deformation of the rotating portion 132 itself.

In addition, an outer peripheral surface of the blocking wing 132a radially extends out of a force applying member 132e, such as a handle, for being held by fingers of a user, so that when the force applying member 132e is rotated, the blocking wing 132a and the rotating shaft 132c can rotate synchronously.

Therefore, when the rotating shaft 132c is inserted into the inserting hole 131b, the pair of hooks 132d can enter the annular groove 131i along the pair of guiding inclined surfaces 131j, so that after the pair of hooks 132d are elastically restored, the upper edge of the annular groove 131i is used as a stop, and the rotating portion 132 is prevented from axially disengaging from the positioning portion 131.

Therefore, when the force applying element 132e is rotated, the blocking wing 132a and the rotating shaft 132c rotate synchronously, and are selectively fastened to the terminal slot 131h or the initial slot 131g by the tenon 132b, and whether the blocking wing 132a covers the supporting recess 131d is used as a basis for locking or unlocking the electronic device 30 (see fig. 14 to 17)). If the electronic device 30 is in the locked state, at least a portion of the blocking wing 132a and the supporting recess 131d together sandwich the positioning groove 302 of the electronic device 30, so that the electronic device 30 is stably positioned without shaking.

Referring to fig. 7, a top view of the rotating portion 132 attached to the positioning portion 131 is shown to show that the holder 1 is in an unlocking configuration for the electronic device 30. As can be clearly seen from fig. 7, the blocking wing 132a is a semicircular fan-shaped body, and the supporting recess 131d is not covered by the blocking wing 132a at all; the tenon 132b is locked and positioned in the initial slot 131g, so that the rotation part 132 is not rotated by vibration.

Referring to fig. 8, a top view of the rotating portion 132 rotating to another angle relative to the positioning portion 131 is shown to show that the holder 1 is also locked to the electronic device 30. As is clear from fig. 8, the blocking wing 132a partially shields the supporting recess 131 d; the tenon 132b is locked and positioned in the terminal slot 131h, and the rotation part 132 is prevented from rotating due to vibration.

As shown in fig. 9 to 17, schematic diagrams of a first embodiment of the holder 1, a plate 20 and an electronic device 30 are shown in the installation process, wherein the plate 20 is a circuit board, and the electronic device 30 is a circuit board selected from a Wi-Fi wireless network card, a 3G network card or an m.2 solid state disk. When assembling, the assembling personnel of the assembly factory first inserts the main body 11 into the through hole 205a of the plate hole 205 (shown in fig. 10), then slides the pair of grooves 121 into the connecting groove 205b communicating with the through hole 205a (shown in fig. 11), and then fastens the fastening tenons 205c in the connecting groove 205b into the corresponding fastening grooves 122 (shown in fig. 12), so that the main body 11 can be connected to the plate hole 205 by the plate fixing structure 12 without sliding and displacement.

Then, inserting an inserting part 301 at one end of an electronic device 30 above the plate 20 into a first connector 201 on the plate 20; and moves down a positioning groove 302 at the other end into the supporting recess 131d of the locking structure 13 above (shown in fig. 13 and 14). At this time, the assembler rotates the force applying member 132e in a counterclockwise direction to rotate the blocking wing 132a and the tenon 132b thereof and the rotating shaft 132c and the at least one hook 132d thereof synchronously, so as to rotate the at least one hook 132d in the annular groove 131i of the inserting hole 131b and disengage the tenon 132b from the initial slot 131g until touching a blocking flange 131c and being locked into the terminal slot 131h, so that the blocking wing 132a partially covers the supporting recess 131d and sandwiches the other end of the electronic device 30 together with the supporting recess 131d to form a locked configuration of the electronic device 30 (shown in fig. 15 and 17).

Similarly, an inserting portion 301 of one end of another electronic device 30 below the board 20 is inserted into a second connector 202 on the board 20; and the other end of the positioning groove 302 is moved down and placed in the supporting recess 131d of the locking structure 13 below (not shown due to the projection angle). At this time, the assembling personnel can rotate the force applying member 132e in the aforementioned manner to enable the blocking wing 132a to partially shield the supporting recess 131d and to clamp the other end of the electronic device 30 together with the supporting recess 131d, so as to form a locked configuration for the electronic device 30 (shown in fig. 15 and 17).

Therefore, through the above operations, the fixing device 1 can be fixed on the board 20, and the two electronic devices 30 can form a stable positioning effect, so that the two electronic devices 30 can be electrically connected to the first connector 201 and the second connector 202 without shaking.

As shown in fig. 18 to 21, which respectively disclose second, third, fourth and fifth embodiments of the fastener, the second to fifth embodiments have the same reference numerals (symbols) used to designate the same components as compared with the first embodiment, and since the second to fifth embodiments share many shared components with the first embodiment, only the difference therebetween will be described in detail later.

As shown in fig. 18, the force applying element 132e of the second embodiment is implemented by forming a linear rotation slot on the top surface of the blocking wing 132a in the axial direction, so as to insert a screwdriver bit of a rotary tool, such as a linear screwdriver, to drive the rotary part 132 to rotate.

As shown in fig. 19, in the third embodiment, the force applying element 132e is implemented by axially protruding a rotating handle on the top surface of the blocking wing 132a for being held by the fingers of the user to drive the rotating part 132 to rotate.

As shown in fig. 20, the fourth embodiment is another modification of the third embodiment, and both are different only in the shape, for example, the rotation handle in the implementation of the force applying member 132e shown in the third embodiment is a rectangle with a circular arc on the top surface. The force applying member 132e of the fourth embodiment is also provided with a rotating handle axially protruding from the top surface of the blocking wing 132a, and the rotating handle is shaped as a symmetrical double-convex tab, which is similarly held by the fingers of the user to drive the rotating portion 132 to rotate.

As shown in fig. 21, the force applying element 132e of the second embodiment is implemented by forming a cross-shaped rotating slot on the top surface of the blocking wing 132a in the axial direction, so as to insert a screwdriver bit of a rotating tool, such as a cross-shaped screwdriver, to drive the rotating part 132 to rotate.

Therefore, the implementation of the present invention has the advantages that the rotation shaft of the rotation part is inserted into the insertion hole of the positioning part, so that the rotation part has a rotation function relative to the positioning part, and is selectively fastened to the terminal slot or the initial slot by the tenon, and whether the support concave is covered by the blocking wing is used for locking or unlocking the electronic device. Furthermore, the board, for example, the circuit board only needs to be provided with one board hole, and the fixer with double-sided fixing function can be installed, so that a first connector and a second connector respectively arranged on two opposite surfaces of the circuit board can be configured in a mirror image manner, and further respective circuit layouts on the two opposite surfaces can be designed symmetrically, thereby obtaining the advantage of reducing research and development cost and time.

The above-mentioned embodiments are intended to illustrate the objects, technical solutions and advantages of the present invention in further detail, and it should be understood that the above-mentioned embodiments are only exemplary embodiments of the present invention and are not intended to limit the present invention, and any modifications, equivalents, improvements and the like made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
