Detailed Description

As shown in fig. 2 to 5, basically, the present embodiment discloses a holder for an electronic device, such as an m.2 solid state disk, wi-Fi wireless network card, 3G network card or circuit board, which includes a positioning member 1 and a clamping member 2. The positioning member 1 and the clamping member 2 are made of polymer insulating material, such as nylon, by injection molding, so as to form an insulating effect.

The positioning member 1 has a geometric shape such as a stepped circular body 11, the body 11 has a raised step 12, the step 12 is axially provided with a plug hole 13, and a pair of blocking edges 121 are radially provided on an outer peripheral surface of the step 12, and a supporting recess 122 is formed between the pair of blocking edges 121. In one embodiment, the cross section of the plugging hole 13 is a non-circular shape, such as an oblong hole. The support recess 122 is provided for a positioning groove 51 at one end of the electronic device 5 (shown in fig. 9), and the pair of blocking edges 121 has an effect of preventing the electronic device 5 from rotating.

Furthermore, in order to enable the positioning member 1 to be fixed in at least one plate hole 41 provided in a plate 4, such as a printed circuit board (shown in fig. 6 to 9), the lower section of the body 11 further includes a plate fixing structure 14. The plate fixing structure 14 includes at least one groove 141 radially formed from an outer circumferential surface of the body 11. As shown in fig. 2 and 3, a pair of grooves 141 are radially formed on the outer peripheral surface of the body 11, and a locking tenon 142 of a locking structure is axially formed in each groove 141.

The plate 4 has at least one keyhole-shaped plate hole 41, the plate hole 41 includes a through hole 411 for the body 11 to pass through, and a connecting slot 412 communicated with the through hole 411 and sleeved by the pair of grooves 141, and a clamping slot 413 of the fastening structure is disposed in the connecting slot 412 corresponding to each of the fastening tenons 142, and the clamping slot 413 is used for fastening the fastening tenons 142, so that the body 11 can be fixed in the plate hole 41 by using the plate fixing structure 14 without sliding and displacement.

In an embodiment, the body 11 below the pair of grooves 141 radially protrudes toward the direction of the connecting slot 412 to form a direction indicating tenon 143, so that when a user installs the positioning element 1 on the board 4, the direction indicating tenon 143 can only be inserted into the connecting slot 412, so as to avoid the defect that the electronic device 5 cannot be installed due to the misplacement of the positioning element 1 in the front-back direction, and thus the electronic device has a foolproof (misplug) function.

The clamping member 2 has a clamping piece 21, and the clamping piece 21 axially protrudes out to have the same cross-section shape as the insertion hole 13, for example, an oblong fixing pin 22 inserted into the insertion hole 13, so that the rotation preventing effect can be generated by the non-circular cross-section shape of the fixing pin 22 and the insertion hole 13. Furthermore, a fastening structure, such as at least one fastening groove 221 and a fastening ring 131 (shown in fig. 4 and fig. 5), is disposed on the adjacent peripheral surfaces of the fixing pin 22 and the plugging hole 13, so that the fixing pin 22 is inserted into the plugging hole 13 and is not axially separated, and the clamping piece 21 is used to close the upper portion of the supporting recess 122, so that the clamping piece 21 and the step 12 jointly enclose the positioning groove 51 (shown in fig. 10 and fig. 12) of the electronic device 5, thereby forming a stable positioning effect of the electronic device 5 and preventing shaking.

The fastening structure is not limited to the above embodiment, but at least one fastening groove is disposed in the plugging hole 13, and the fastening ring is disposed on the peripheral surface of the fixing pin 22.

Further, an auxiliary pulling plate 23 is integrally connected to the opposite direction of the clamping plate 21, so as to facilitate the fixing pin 22 to insert and withdraw the inserting hole 13.

In order to make the positioning element 1 and the clamping element 2 be integrally injection-molded, two ends of a connecting strip 3 are respectively connected with the positioning element, such as the body 11 and the clamping piece 21 or the auxiliary pulling piece 23 of the clamping element 2, and the connecting strip 3 is conveniently bent, so that a thinner bending section 31 is arranged at a position of a roughly middle section of the connecting strip 3 to facilitate bending of the connecting strip 3 towards the positioning element 1, and simultaneously, the reaction force generated by the connecting strip 3 can be reduced.

Referring to fig. 6 to 10, schematic diagrams of the mounting process of the holder, a board 4 and an electronic device 5 are shown, wherein the board 4 is implemented as a printed circuit board, two board holes 41 are arranged on the board 4 in a linear manner, and the electronic device 5 is implemented as an elongated m.2 solid state disk. When the user performs the assembly, first, an appropriate plate hole 41 (shown in fig. 6) is selected according to the length of the electronic device 5. The direction indicating tongue 143 of the positioning member 1 is then aligned with the receiving groove 412 of the plate hole 41, and the body 11 is inserted into the through hole 411 of the plate hole 41 (shown in fig. 7). The pair of grooves 141 are then slid into the receiving slots 412 in communication with the through holes 411, such that each of the locking slots 413 in the receiving slots 412 is locked to a corresponding one of the locking tongues 142 (shown in fig. 8), such that the body 11 can be mounted in the plate hole 41 by the plate fixing structure 14 without sliding or displacement.

Next, a connector 42 is inserted into the board 4 at a plugging portion (not labeled due to the projection angle) of one end of the electronic device 5 above the board 4; and a positioning groove 51 at the other end is moved down and placed into the supporting recess 122 (shown in fig. 9).

Then, the user holds the auxiliary pulling piece 23 of the clamping piece 2, bends the connecting strip 3 inwards at the bending section 31, and inserts the fixing pin 22 of the clamping piece 21 into the inserting hole 13 of the column 11, so that the at least one buckling groove 221 of the fixing pin 22 is buckled in the buckling ring 131 in the inserting hole 13 (shown in fig. 10 and 11).

Finally, the top surface of the supporting recess 122 is closed by the clamping piece 21, so that the clamping piece 21 and the step 12 jointly cover the positioning groove 51 (shown in fig. 10 and 12) of the electronic device 5, and the electronic device 5 has a stable positioning effect and does not shake.

If the electronic device 5 is replaced with a short m.2 solid state disk, the user only has to reverse the above-mentioned mounting steps to separate the elongated electronic device 5 and the holder from the board 4. The retainer is then mounted in the other plate hole 41, and the short electronic device 5 is assembled according to the above-mentioned mounting steps, so that the retainer can be quickly detached and mounted on the plate 4, so as to be suitable for the purposes of electronic devices 5 with different lengths.

Therefore, the utility model has the beneficial effects that the positioning piece of the fixer can be quickly assembled and disassembled above the plate, so that the positioning piece can be arranged in a selected plate hole on the plate to adapt to electronic devices with different lengths. Furthermore, the cross sections of the fixing pin and the inserting hole for inserting the fixing pin are non-circular, such as oblong, so that the fixing pin has the directional effects of preventing rotation and limiting the direction of the fixing pin in the inserting hole. Further, the positioning frame is connected with the clamping piece through the connecting strip, and the positioning frame and the clamping piece are not easy to fall off when being installed or detached.

The foregoing embodiments have been provided for the purpose of illustrating the general principles of the present utility model, and are not to be construed as limiting the utility model. Those skilled in the art will appreciate that the features recited in the various embodiments of the utility model and/or in the claims may be combined in various combinations and/or combinations even if such combinations or combinations are not explicitly recited in the utility model.
