Description

Technical Field

[0001] This invention relates to the field of retainer technology, and more particularly to a retainer for electronic devices with different length specifications, such as M.2 solid-state drives. Background Technology

[0002] The technique of using a fixture to fix an electronic device to a substrate, such as a circuit board, is well known, as shown in Patent Publication No. M515255 (corresponding to Patent No. 201520485399.7).

[0003] like Figure 1a The diagram shows an exploded perspective view of an electronic device 20 (e.g., an M.2 solid-state drive), a substrate 10 (e.g., a printed circuit board), and a fixing device 30. One end of the electronic device 20 has a contact portion 201 with multiple contact terminals, while the other end has a semi-circular positioning groove 202 for positioning. One end of the substrate 10 has an electrical connector 101, and four linearly arranged board holes 102 are formed on its top surface corresponding to different lengths of the electronic device 20, such as 30mm, 42mm, 60mm, and 80mm. Each board hole 102 houses a positioning nut 103. The fixing device 30 includes a positioning stud 301 that locks onto a corresponding positioning nut 103 according to the length of the electronic device 20, for example, 80mm, and a positioning screw 302 that locks onto the positioning stud 301.

[0004] like Figure 1b As shown, during assembly, the contact portion 201 of the electronic device 20 is inserted into the electrical connector 101 of the plate 10, while the positioning groove 202 at the other end is clamped between the positioning stud 301 and the positioning screw 302 of the fixing device 30, so that the positioning screw 302 and the positioning stud 301 together clamp the positioning groove 202, thereby allowing the electronic device 20 to be fixed on the plate 10.

[0005] However, the aforementioned fixing device 30 used to position and fix the electronic device 20 has a drawback: the positioning nuts 103 are surface mount devices (SMD) soldered into the pre-set holes 102 in the board 10, which increases the production cost of the board. Furthermore, the positioning nuts 103 allow the positioning studs 301 to be selectively installed and removed from the positioning nuts 103 according to the size of the electronic device 20 to be installed; this method requires tools and is done manually, which is time-consuming and labor-intensive, and positioning is difficult, making it not an effective solution. Moreover, if the metal positioning screws 302 are accidentally dropped into an electronic device, it can easily cause serious damage to the electronic components due to short circuits, thus requiring urgent improvement. Summary of the Invention

[0006] The main objective of this invention is to provide a retainer for electronic devices, which is mounted on a substrate, such as a printed circuit board. This retainer can be quickly changed to a positioning position without the need for tools to disassemble or assemble, so as to be suitable for electronic devices of different lengths, such as M.2 solid-state drives. This allows the retainer to be applied to electronic devices of different lengths. Moreover, the electronic device can be disassembled within the retainer, rather than manually adjusting the positioning position on the substrate. In particular, the retainer has the advantage of being reusable.

[0007] To achieve the aforementioned objectives, the present invention provides a fixture for an electronic device, comprising a fixing member and a sliding member. The fixing member includes a base consisting of a base plate, a pair of front baffles spaced apart at one end of the base plate, and a rear end wall at the other end of the base plate. A pair of protruding rails are provided on the top surface of the base plate, and the side walls of the pair of protruding rails, depending on the different length positions of the electronic device, respectively, provide a pair of first positioning tenons and at least a pair of second positioning tenons spaced apart towards the center. Each of the second positioning tenons has a guide slope extending obliquely backward on its side. A pair of guide rods, each fitted with a telescopic spring, connect the rear end wall and the pair of front baffles. The sliding member includes a slide base, a step disposed on the slide base, and a pair of elastic springs disposed in a hollowed-out groove in the step and extending forward. The slide includes a support platform for supporting an electronic device, and a pair of sliding wings through which the pair of guide rods pass and abut against the pair of telescopic springs; the front edge of the seat step has a positioning protrusion for positioning corresponding to a positioning groove of the electronic device, and at least one clamping tooth for clamping a rear end edge of the electronic device; and each of the pair of elastic arms has a positioning slot at its free end that can abut against the pair of first positioning tenons or the pair of the aforementioned second positioning tenons, and the pair of positioning slots are locked by the elastic force of the pair of telescopic springs; when the sliding member moves forward or backward along the pair of guide rods, the pair of positioning slots can selectively elastically abut against the pair of first positioning tenons or the pair of the aforementioned second positioning tenons to adjust the length distance and lock the sliding member, thereby adapting to electronic devices of different length specifications.

[0008] In one embodiment, the pair of first positioning tenons corresponds to an electronic device with a length of 30 mm, while the number of the second positioning tenons is three pairs, corresponding to electronic devices with lengths of 42 mm, 60 mm and 80 mm respectively.

[0009] In one embodiment, a front opening is formed between the pair of front baffles to accommodate the sliding member; and a left side wall and a right side wall are respectively provided on the left and right sides of the base plate, and the left side wall and the right side wall are connected to the rear end of the base by a rear top plate, and together with the base plate, form a rear opening so as to allow the rear end wall to be fitted and installed.

[0010] In one embodiment, a snap-fit ​​mechanism is provided between the top and bottom abutting surfaces of the rear end wall and the rear opening, so as to snap the rear end wall into the rear opening.

[0011] In one embodiment, the latching mechanism includes at least one latching groove respectively provided on the rear top plate and the bottom plate, and at least one latching hook respectively provided on the top surface and the bottom surface of the rear end wall; the latching hooks are each latched into a latching groove corresponding to the rear opening, so that the rear end wall is attached to the base.

[0012] In one embodiment, the top surfaces of the left side wall and the right side wall extend laterally toward the center from between the pair of front baffles and the rear top plate, respectively, with a left flange and a right flange respectively; wherein the left flange and the right flange are provided with a left notch and a right notch facing each other corresponding to the length dimension of the slider, so that the slider can be placed on the base plate between the pair of left and right notches.

[0013] In one embodiment, the rear ends of the pair of guide rods are integrally formed with the rear end wall by an embedded injection method, while the front ends are each inserted into a rod hole opened in a corresponding front baffle wall.

[0014] In one embodiment, the fastener is further positioned and fixed to a plate, so the base plate has a through hole in the longitudinal direction for a locking member to pass through, and there is a receiving hole above the through hole for receiving a head of the locking member; wherein the locking member is engaged with a pre-set locking hole in the plate without sliding or displacement.

[0015] In one embodiment, the bottom surface of the base plate further includes at least one plate positioning structure. Each plate positioning structure includes an L-shaped tenon protruding from the bottom surface of the base plate and a locking tenon extending rearward from the L-shaped tenon. The plate has a plate hole corresponding to the position of each plate positioning structure. The plate hole includes a slot for inserting the L-shaped tenon and pushing it rearward, and a slot for positioning the locking tenon and communicating with the slot.

[0016] In one embodiment, there are two clamping teeth, each located on the left and right sides of the positioning protrusion, and the clamping teeth form a gap with the support platform corresponding to the thickness of the electronic device; wherein the positioning protrusion has a first guide surface, and each of the at least one clamping tooth has a second guide surface, for guiding, positioning and clamping the electronic device.

[0018] In one embodiment, the bottom surface of the slide is provided with a groove that connects to the pair of convex rails.

[0019] In one embodiment, an arc-shaped spring is provided between the pair of elastic arms. The arc-shaped spring provides an auxiliary elastic force so that the pair of positioning slots can be firmly abutted against the pair of first positioning tenons or the pair of the aforementioned second positioning tenons.

[0020] In one embodiment, a pair of pressure handles extend from the top of the pair of elastic arms; when the pair of pressure handles are pressed, the pair of elastic arms move together toward the center and cause the pair of positioning slots to disengage from the pair of the aforementioned second positioning tenons, thereby unlocking the slider, which can be pushed forward along the pair of guide rods, and cause the pair of telescopic springs to extend and release, and cause the pair of positioning slots to abut against another pair of the aforementioned second positioning tenons or the pair of first positioning tenons.

[0021] In one embodiment, the rear end of the seat extends upward to form a push handle for finger pushing; when the slider slides backward along the pair of guide rods, in addition to compressing the pair of telescopic springs, the pair of positioning slots move along the inner wall of the pair of convex rails, pass over the pair of guide ramps, and abut against the pair of the aforementioned second positioning tenons.

[0095] like Figures 2 to 5 As shown, it discloses a retainer for an electronic device, such as an M.2 solid-state drive, the retainer comprising a retainer 1 injection molded from an insulating material, such as plastic, and a slider 2.

[0096] The fastener 1 includes a geometrically shaped, for example, rectangular base 11, which has a base plate 111, a pair of spaced-apart front baffles 112, and a rear baffle 113. The top surface of the base plate 111 has a pair of opposing sidewalls of the rails 12 mounted on it, according to an electronic device 20 (displayed on...). Figure 8 For example, for M.2 solid-state drives of different lengths, such as 30mm, 42mm, 60mm, and 80mm, a pair of first positioning tenons 121 and at least a pair of second positioning tenons 122 are respectively provided at intervals towards the center; wherein each of the second positioning tenons 122 has a guide slope 122a extending obliquely backward on its side to facilitate guiding the movement and positioning of the sliding member 2. Figure 2 As shown, the pair of first positioning tenons 121 correspond to an electronic device 20 with a length of 30 mm, while the number of the second positioning tenons 122 is three pairs, corresponding to electronic devices 20 with lengths of 42 mm, 60 mm and 80 mm respectively.

[0097] A front opening 13 is formed between the two front baffles 112 to accommodate the sliding member 2. The base 11 is provided with a left side wall 114 and a right side wall 115 on the left and right sides of the base plate 111, respectively. The left side wall 114 and the right side wall 115 are connected to the rear end of the base 11 by a rear top plate 116, and together with the base plate 111, they form a rear opening 14 to allow the rear end wall 113 to be fitted and installed.

[0098] To ensure the rear end wall 113 is securely attached to the rear opening 14, a snap-fit ​​mechanism 15 is provided on the top and bottom abutment surfaces of both, allowing the rear end wall 113 to be snapped into the rear opening 14. The snap-fit ​​mechanism 15 includes at least one snap groove 151 on the rear top plate 116 and the bottom plate 111, and at least one snap hook 152 on the top and bottom surfaces of the rear end wall 113. During assembly, the snap hooks 152 of the rear end wall 113 snap into the corresponding snap groove 151 in the rear opening 14, completing the connection between the rear end wall 113 and the base 11.

[0099] Furthermore, to enable the slider 2 to slide and be positioned within the base 11, a guide rod 16 extends from the rear end wall 113 towards each of the pair of front baffles 112. The rear ends of the guide rods 16 are integrally formed with the rear end wall 113 by an embedded injection method, while the front ends are each inserted into a rod hole 112a in a corresponding front baffle 112. In particular, each guide rod 16 is fitted with a telescopic spring 17, and the two ends of the telescopic spring 17 abut against the rear end wall 113 and the slider 2, respectively.

[0100] In addition, in order to secure the fastener 1 to a plate 10 (shown in...), Figure 6 For example, on a printed circuit board, the base plate 111 has a through hole 111a for a locking member 111c to pass through, and above the through hole 111a is a receiving hole 111b for receiving a head 111d of the locking member 111c.

[0101] Furthermore, the top surfaces of the left side wall 114 and the right side wall 115 extend laterally towards the center from between the pair of front baffles 112 and the rear top plate 116, respectively, to regulate the movement of the slider 2 within the base 11. The left side flange 114a and the right side flange 115a are respectively provided with a left notch 114b and a right notch 115b corresponding to the length of the slider 2, allowing the slider 2 to be positioned on the base plate 111 between the left and right notches 114b and 115b.

[0102] In addition, please see Figure 3To enable the fastener 1 to be positioned on the plate 10, the bottom surface of the base plate 111 further includes at least one plate positioning structure 18. The plate positioning structure 18 includes an L-shaped tenon 181 protruding from the bottom surface of the base plate 111, and a latching tenon 182 extending rearward from the L-shaped tenon 181. Figure 3 In the middle, the bottom surface of the base plate 111 has three plate positioning structures 18 arranged linearly, and respectively located in the front section, middle section and rear section of the base plate.

[0103] Please see Figure 6 The plate 10 has a plate hole 102 corresponding to the position of each plate positioning structure 18. The plate hole 102 includes a slot 102a for inserting the L-shaped tenon 181 and pushing it backward, and a slot 102b for the tenon 182 to be inserted and positioned and connected to the slot 102a.

[0104] When at least one plate positioning structure 18 of the fastener 1 is respectively engaged in a plate hole 102 of the plate 10 according to the aforementioned assembly process (shown in...) Figure 10 and Figure 11 Then, the locking member 111c is inserted into the through hole 111a of the base plate 111 and engaged with a pre-set locking hole 104 in the plate 10, so as not to slide or shift, and the head 111d of the locking member 111c is received in the receiving hole 111b (shown in Figure 10 This completes the process of connecting the fastener to the plate 10. It also allows for further definition of the length of each of the first positioning tenons 121 and the second positioning tenons 122 from an electrical connector 101 on the plate 10, for example, 30mm, 42mm, 60mm, and 80mm.

[0105] like Figure 4a and Figure 4b As shown, the slider 2 is a rectangular stepped base, which includes a slide 21, a step 22 disposed on the slide 21, and a pair of elastic arms 23 disposed in a hollow groove 221 of the step 22 and extending forward. The front end of the slide 21 is provided with a support platform 211 for supporting the electronic device 20, and the front edge of the step 22 protrudes with a positioning protrusion 222 for positioning corresponding to a positioning groove 202 of the electronic device 20, and at least one clamping tooth 223 for clamping the rear end edge of the electronic device 20.

[0106] The clamping teeth 223 are of two types, each located on the left and right sides of the positioning protrusion 222, and form a gap with the support platform 211 corresponding to the thickness of the electronic device 20. Furthermore, the positioning protrusion 222 has a first guide surface 222a, and each of the at least one clamping tooth 223 has a second guide surface 223a, to facilitate the guiding, positioning, and clamping of the electronic device 20.

[0107] Furthermore, a pair of sliding wings 212 extend from the left and right sides of the slide block 21 and are accommodated between the base plate 111 and the left flange 114a and the base plate 111 and the right flange 115a. Each sliding wing 212 has a guide hole 213 through which a corresponding guide rod 16 passes and a telescopic spring 17 abuts, allowing the sliding member 2 to move elastically back and forth along the pair of guide rods 16. The telescopic spring 17, sleeved outside each guide rod 16, is located between the guide hole 213 and the rear end wall 113 and constantly applies an extension force to the sliding member 2, causing the front ends of the pair of sliding wings 212 of the sliding member 2 to abut against the pair of front baffles 112.

[0108] In addition, a groove 214 on the bottom surface of the slide block 21 can be fitted onto the pair of convex rails 12 to reduce friction and allow the slider 2 to slide back and forth within the base 11.

[0109] Furthermore, each of the pair of elastic arms 23 has a positioning groove 231 at its free end that can abut against the pair of first positioning tenons 121 or the pair of second positioning tenons 122. The pair of positioning grooves 231 will not move due to the pushing action of the stretching elastic force, and will form the expected locking shape. Therefore, the pair of positioning grooves 231 of the slider 2 can selectively and elastically abut against the pair of first positioning tenons 121 or the pair of second positioning tenons 122 to form the adjustment of the length distance and the locking of the slider 2.

[0110] In addition, an arc-shaped spring piece 232 is provided between the pair of elastic arms 23. The arc-shaped spring piece 232 provides an auxiliary elastic force so that the pair of positioning slots 231 can be firmly abutted against the pair of first positioning tenons 121 or the pair of second positioning tenons 122.

[0111] In particular, to unlock (release the abutment) the pair of elastic arms 23, a pair of pressure handles 233 extend from above the pair of elastic arms 23. When the pair of pressure handles 233 are pressed simultaneously, the pair of elastic arms 23 move together toward the center and cause the pair of positioning slots 231 to disengage from a pair of second positioning tenons 122, thereby achieving the unlocking effect.

[0112] Similarly, a push handle 224 extends upward from the rear end of the seat step 22 to facilitate pushing the push handle 224 with a finger, and slide the slider 2 backward along the pair of guide rods 16. In addition to compressing the pair of telescopic springs 17, the pair of positioning slots 231 will move along the inner wall of the pair of convex rails 12 to pass over the pair of guide ramps 122a and abut against the pair of second positioning tenons 122 to complete the operation of quickly changing to another positioning position, thereby being suitable for electronic devices 20 of different length specifications.

[0113] Alternatively, by pressing the pair of levers 233 to disengage the pair of positioning slots 231 from the pair of second positioning tenons 122, the slider 2 can be pushed forward along the pair of guide rods 16, causing the pair of telescopic springs 17 to extend and release, and allowing the pair of positioning slots 231 to abut against another pair of second positioning tenons 122 or the pair of first positioning tenons 121, thereby completing the operation of quickly changing to another positioning position, thus making it suitable for electronic devices 20 of different length specifications.

[0114] When assembling the fixing member 1 and the sliding member 2, firstly, each of the telescopic springs 17 is sleeved onto a guide rod 16 of the rear end wall 113. Next, the sliding member 2 is inserted into the pair of left and right notches 114b and 115b between the left flange 114a and the right flange 115a of the base 11, so that the rail groove 214 at the bottom of the sliding member 2 is sleeved onto the pair of protruding rails 12 of the base plate 111, and the pair of sliding wings 212 are accommodated between the corresponding base plate 111 and the left flange 114a and the base plate 111 and the right flange 115a.

[0115] Subsequently, the assembler presses each of the pressure handles 233 of the pair of elastic arms 23 and pushes the slider 2 forward until the pair of sliding wings 212 abut against the pair of front baffles 112, so that each of the guide holes 213 of the pair of sliding wings 212 aligns with the corresponding rod hole 112a, and the pair of positioning slots 231 of the pair of elastic arms 23 abut against the pair of first positioning tenons 121.

[0116] Finally, the rear end wall 113 is fastened to the rear opening 14 of the base 11 using the snap-fit ​​structure 15, so that the pair of guide rods 16, each with a telescopic spring 17, pass through the corresponding guide holes 213 and are inserted into the rod holes 112a, thereby completing the process as described above. Figure 5 The assembly process of the fastener is shown.

[0117] Please see Figures 6 to 9 ,in Figure 6 This shows an exploded 3D view of the fastener before it is assembled with a sheet metal plate. Figure 7 The diagram shows a perspective view illustrating how, according to the aforementioned description of the connection process between the fastener and the plate 10, the fastener can be integrated with the plate 10 using only a locking member 111c.

[0118] Figure 8 and Figure 9 This displays a flowchart of the assembly process between the fixture and an electronic device 20. For example... Figure 8 As shown, firstly, a contact portion 201 at one end of an electronic device 20 with a length of 30mm is inserted into the electrical connector 101 of the plate 10; then, the other end of the electronic device 20 is pressed down, causing a rear end edge and a positioning groove 202 to move down along the first guide surface 222a of the positioning protrusion 222 and the second guide surfaces 223a of the clamping teeth 223, respectively, so that the sliding member 2 slightly elastically displaces and returns until the positioning groove 202 is fitted onto the positioning protrusion 222, and the rear end edge automatically engages in the gap between the clamping teeth 223 and the support platform 211, so that the electronic device 20 forms as shown. Figure 9 The positioning effect shown is firm and does not cause any shaking, thus ensuring the electrical connection between the electronic device 20 and the plate 10.

[0119] like Figures 10 to 13 As shown, they respectively display Figure 9 A cross-sectional view taken along lines AA, BB, CC, and DD. From Figure 10 and Figure 11 Various details can be observed when the fastener is combined with the plate 10 and the electronic device 20; from Figure 12 The internal space configuration after the fixed component 1 and the sliding component 2 are combined can be observed; and from another perspective... Figure 13 It can be observed that the pair of positioning slots 231 of the sliding member 2 elastically abut against the pair of first positioning tenons 121, and the relative positional relationship of the pair of convex rails 12, the pair of guide rods 16 and the pair of telescopic springs 17 and the sliding member 2, so as to accommodate the electronic device 20 with a length of 30mm. Behind the pair of first positioning tenons 121, there are three pairs of second positioning tenons 122 with dimensions marked as 42mm, 60mm and 80mm respectively.

[0120] Please see Figures 14 to 16 The diagrams show perspective views of various lengths of electronic devices mounted on the fixture. To replace electronic devices of different lengths, the sliding member 2 can be quickly repositioned within the fixture 1 according to the aforementioned description. Figure 14 The installation of the electronic device 20, which has a length of 42 mm, is shown. Figure 15 The installation of the electronic device 20, which is 60 mm in length, is shown; and Figure 16 The installation of the electronic device 20, which has a length of 80 mm, is shown.

[0121] like Figures 17a to 17bAs shown, a second embodiment of the slider 2 is disclosed. Compared with the first embodiment, the same reference numerals are used to indicate the same components in the second embodiment. Since the second embodiment and the first embodiment share many components, only the differences between the two are described in detail below.

[0122] The difference between this embodiment and the first embodiment is that the pair of elastic arms 23 and the seat step 22 of the slider 2 are not provided with a pair of pressure handles 233 and a push handle 224 as shown in the first embodiment. Therefore, when unlocking, the user places two fingers on a recess of the arc-shaped spring piece 232 and a rear edge of the seat step 22 respectively, and applies force between the two fingers, causing the pair of elastic arms 23 to move together toward the center, and causing the pair of positioning slots 231 to disengage from the pair of second positioning tenons 122, thereby achieving the unlocking effect.

[0123] Therefore, the benefit of implementing this invention is that the retainer can be adjusted to quickly change the positioning position of the sliding member within the retainer, adapting to electronic devices of different lengths without disassembly or reassembly. Furthermore, when the electronic device is pressed down, the positioning protrusion and at least one clamping tooth provide automatic positioning and engagement. Moreover, the retainer can be fixed to the plate with only a single locking member, offering advantages such as easy assembly, recyclability, and reusability.

[0124] The embodiments of this disclosure have been described above. However, these embodiments are for illustrative purposes only and are not intended to limit the scope of this disclosure. Although various embodiments have been described above, this does not mean that the measures in the various embodiments cannot be used advantageously in combination. Various substitutions and modifications can be made by those skilled in the art without departing from the scope of this disclosure, and all such substitutions and modifications should fall within the scope of this disclosure.
