[0046] To make the objectives, features, and advantages of this disclosure more apparent and understandable, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0047] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0048] Combination Figure 1 and Figure 2 As shown, this embodiment of the present disclosure provides a non-removable fastener, which includes a fixed body 2 and a movable body 1; a limiting latching part 21 and an installation connecting part 22 are provided on the side surface of the fixed body 2; the movable body 1 is arranged parallel to and spaced apart from the fixed body 2, and one end of the movable body 1 is elastically connected to the fixed body 2; wherein, the fixed body 2 can be fixedly installed on the circuit board through the installation connecting part 22, and can be docked and limitedly latched with the component to be fixed through the limiting latching part 21; the movable body 1 also has a cover pressing part 11, which can cover and fix the component to be fixed; the movable body 1 can also rotate around one end of the fixed body 2 so that the cover pressing part 11 no longer covers and fixes the component to be fixed.

[0049] The non-removable fixing device provided in this embodiment can be specifically applied to the installation and fixing of components such as solid-state drives or wireless network cards in computer circuit boards. The usage process is described in detail below.

[0050] During installation, the non-removable fastener is first fixedly mounted on the circuit board via the mounting connection 22, so that the limiting locking part 21 on the side of the fastener 2 and the locking mounting platform on the circuit board can together form a limiting part for locking and limiting the component to be fixed; then, one side of the component to be fixed is locked onto the limiting locking part 21 of the fastener 2, thus achieving the limiting and fixing of the component to be fixed in the horizontal plane; finally, the cover pressing part 11 in the movable part 1 is used to press and fix the component to be fixed, thus achieving the limiting and fixing of the component to be fixed in the horizontal plane, thereby achieving stable locking and limiting of the component to be fixed in the circuit board.

[0051] Furthermore, when it is necessary to remove the component to be fixed from the circuit board, simply rotate the movable part 1 around one end of the fixed part 2 so that the cover 11 no longer covers and fixes the component to be fixed. In this way, the component to be fixed can be unlocked in the vertical direction, so that the component to be fixed can be taken out of the circuit board in the vertical direction.

[0052] In addition, the non-removable fastener can be made of sheet metal and stamped as a whole, and can be installed in the circuit board by welding. This can ensure the secure and reliable installation of the non-removable fastener on the circuit board, and can also realize the grounding function of the component to be fixed.

[0053] In summary, the embodiments of this disclosure provide a non-removable fastener that can simultaneously limit and fix the component to be fixed in the horizontal and vertical directions through the limiting snap-fit ​​part 21 in the fixed body 2 and the cover pressing part 11 in the movable body 1. When disassembling, it is only necessary to rotate the movable body 1 around one end of the fixed body 2 so that the cover pressing part 11 is no longer pressing, without having to remove the non-removable fastener from the circuit board. It has the advantages of simple structure, convenient snap-fit ​​and removal of the component to be fixed, no need to use screws, and avoidance of bumps and collisions affecting other components in the circuit board.

[0054] In one embodiment, the limiting and locking part 21 includes a first limiting part 211 and a second limiting part 212 disposed in the side surface; the first limiting part 211 has a horizontal limiting surface disposed perpendicular to the side surface; the second limiting part 212 has a vertical limiting surface disposed parallel to the side surface; the limiting and locking part 21 can be connected and locked with the bottom side and vertical side of the component to be fixed through the horizontal limiting surface and the vertical limiting surface, respectively.

[0055] Specifically, in combination Figure 1 and Figure 2In further detail, the limiting and locking part 21 is specifically configured to include a first limiting part 211 and a second limiting part 212 disposed in the side surface. The first limiting part 211 has a horizontal limiting surface disposed perpendicular to the side surface, and the second limiting part 212 has a vertical limiting surface disposed parallel to the side surface. In this way, when one side of the component to be fixed is limited and locked with the limiting and locking part 21 in the side surface of the fixing body 2, the horizontal limiting surface can be used to abut against the bottom wall surface of the component to be fixed, and the vertical limiting surface can be used to abut against the side wall surface of the component to be fixed, thereby stably and reliably limiting and fixing the component to be fixed in the X and Y directions in the horizontal plane.

[0056] Furthermore, the first limiting part 211 and the second limiting part 212 can both be specifically configured as outwardly protruding plates, and both can be integrally stamped with the fixing body 2.

[0057] The specific arrangement of the aforementioned limiting and mounting part 21 has the advantages of simple structure and the ability to limit and fix the component to be fixed in at least two different directions.

[0058] In one embodiment, the mounting connection portion 22 includes a first mounting portion 221 and a second mounting portion 222 disposed at the bottom of the side surface; the first mounting portion 221 is disposed perpendicular to the side surface and is used for soldering and fixing to the circuit board; the second mounting portion 222 is disposed parallel to the side surface and is used for inserting and fixing to the circuit board.

[0059] Specifically, in combination Figure 1 and Figure 2 In further detail, the mounting connection part 22 is specifically configured to include a first mounting part 221 and a second mounting part 222 disposed at the bottom of the side surface. The first mounting part 221 is perpendicular to the side surface, and the second mounting part 222 is parallel to the side surface. This allows the first mounting part 221 to abut against the soldering station in the circuit board for welding and fixing in the horizontal plane. Moreover, the second mounting part 222 can be inserted and fixed in the circuit board in the vertical direction, which can achieve the pre-installation positioning of the non-removable fixing device in the circuit board before welding and fixing.

[0060] The specific arrangement of the above-mentioned mounting connection part 22 has the advantages of simple structure and the ability to achieve precise pre-installation and firm welding fixation with the circuit board.

[0061] In one embodiment, the cover pressing part 11 includes an inclined guide section 111 and a cover pressing section 112 connected to each other; the inclined guide section 111 is inclined away from the movable part 1 in a downward direction; the cover pressing section 112 is located at the lowermost end of the inclined guide section 111 and extends vertically toward the movable part 1.

[0062] Specifically, in combination Figure 1 and Figure 2 In further detail, the cover pressing part 11 is specifically configured to include an inclined guide section 111 and a cover pressing section 112 connected to each other. The inclined guide section 111 is inclined from top to bottom, gradually moving away from the movable part 1. The cover pressing section 112 is located at the lower end of the inclined guide section 111 and extends vertically toward the movable part 1. In this way, the cover pressing part 11 can form a hook-lock structure similar to an arrow. When the component to be fixed is installed, it can be moved and squeezed gradually along the inclined guide section 111 from top to bottom. After the component is fully pressed into place, the movable part 1 will reset under its own elastic deformation force and be firmly covered and fixed to the top wall of the component to be fixed by the cover pressing section 112. When the component to be fixed needs to be removed, simply rotate the movable part 1 away from the fixed part 2, causing the cover pressing section 112 to no longer cover the top wall of the component to be fixed. At this time, the component to be fixed can be lifted and removed from bottom to top.

[0063] The specific arrangement of the cover pressing part 11 described above has the advantages of simple structure and stable installation of the component to be fixed by means of barbed locking.

[0064] In one embodiment, the fixing body 2 is also provided with a relief part 23 for avoiding the cover pressing part 11; the inclined guide section 111 and the cover pressing section 112 can both partially extend out of the relief part 23 and protrude from the side surface of the fixing body 2.

[0065] Specifically, in combination Figure 1 and Figure 2 In further detail, the aforementioned clearance portion 23 can be specifically, but not limited to, a clearance opening recessed in the top wall of the fixing body 2. In this way, the inclined guide section 111 and the cover section 112 in the movable body 1 can partially extend out of the clearance opening and protrude from the side surface of the fixing body 2, so as to ensure that the cover section 11 can normally perform the function of covering and fixing the fixing element from top to bottom.

[0066] In one embodiment, the other end of the movable body 1 forms a toggle portion 12; the toggle portion 12 can be toggle toward or away from the fixed body 2 to change the covering pressure state of the covering portion 11 on the fixed element.

[0067] Specifically, in combination Figure 1 and Figure 2 In further detail, the other end of the movable part 1 is set as a toggle part 12, and the toggle part 12 can be toggle away from the fixed part 2 when toggled. In this way, the movable part 1 can be rotated away from the fixed part 2, thereby causing the cover pressing section 112 to no longer press against the top wall of the component to be fixed, thus realizing the function of temporarily canceling the cover pressing section 112 to limit the cover.

[0068] Moreover, when the actuating part 12 is no longer under force, the movable part 1 can be reset under its own elastic deformation force, thereby driving the cover section 112 to press against the top wall of the component to be fixed again, realizing the function of restoring the cover section 112 to cover and limit the position.

[0069] Furthermore, the aforementioned actuating part 12 can also be integrally formed and connected to the movable part 1 by stamping and bending. The actuating part 12 can also be extended outward along the length direction of the movable part 1 by a certain length. In this way, when the actuating part 12 is actuated, it can drive the movable part 1 to rotate away from the fixed part 2 with less effort.

[0070] The specific arrangement of the aforementioned actuating part 12 has the advantages of simple structure and easy to drive the moving part 1 to rotate.

[0071] In one embodiment, the fixed member 2 is further provided with a guide portion 24 extending toward the movable member 1; the actuating portion 12 is disposed above the guide portion 24 and can be reciprocated and slid within the guide portion 24.

[0072] Specifically, in combination Figure 1 and Figure 2 In further detail, the guide part 24 can be specifically, but not limited to, a guide strip, and the upper plate surface of the guide strip can be specifically disposed on the lower bottom surface of the actuating part 12. In this way, when the actuating part 12 is actuated, it can slide back and forth on the upper plate surface of the guide strip. Furthermore, the end of the guide strip can be bent upwards, so that the guide strip can also limit the actuating part 12 through the bending part, avoiding the problem of the actuating part 12 being excessively actuated, causing the moving part 1 to exceed its own elastic deformation range and be accidentally bent and damaged.

[0073] The specific arrangement of the guide part 24 described above has the beneficial effects of simple structure, guiding and limiting the range of movement of the actuating part 12, and preventing accidental bending and damage to the moving part 1.

[0074] In one embodiment, the movable part 1 is provided with a horizontally extending adsorption part 13 on the side opposite to the fixed part 2; the adsorption part 13 can be adsorbed and transported by the robotic arm.

[0075] Specifically, in combination Figure 1 and Figure 2 In further detail, a horizontally extending adsorption part 13 is provided on the side of the movable part 1 facing away from the fixed part 2. The adsorption part 13 can be specifically, but not limited to, an adsorption plate. In this way, the suction head in the robotic arm can be stably adsorbed onto the surface of the adsorption plate, thereby facilitating the robotic arm to automatically grasp and transport the non-removable fixture.

[0076] In one embodiment, one end of the movable part 1 is elastically connected to the fixed part 2 via a U-shaped connecting part 14; the U-shaped connecting part 14 can elastically change its opening and closing angle to drive the movable part 1 to rotate around one end of the fixed part 2.

[0077] Specifically, in combination Figure 1 and Figure 2 In further detail, one end of the movable part 1 is elastically connected to the fixed part 2 via a U-shaped connecting part 14. The U-shaped connecting part 14 can also be connected to the movable part 1 and the fixed part 2 by integral stamping and bending. In this way, when the actuating part 12 on the other side of the movable part 1 is actuated, the movable part 1 can rotate away from the fixed part 2, thereby increasing the opening and closing angle of the U-shaped connecting part 14 and realizing the function of the movable part 1 rotating around one end of the fixed part 2. In this way, when the actuating part 12 on the other side of the movable part 1 is no longer actuated, the U-shaped connecting part 14 can shrink its opening and closing angle under its own elastic force, so that the movable part 1 can rotate and reset towards the fixed part 2.

[0078] The specific arrangement of the U-shaped connecting part 14 described above has the advantages of simple structure and the ability to reciprocate and rotate the moving part 1 by its own elastic deformation.

[0079] In addition, this disclosure also provides a circuit board mounting assembly, which includes a circuit board body 3, a mounting element 4 and the above-mentioned non-removable fastener; wherein, the fastener body 2 is fixedly mounted to the circuit board body 3 through the mounting connection part 22; the mounting element 4 is limited and mounted to the fastener body 2 through the limiting snap-fit ​​part 21 and the cover pressing part 11.

[0080] Specifically, in combination Figure 3 In further detail, the circuit board mounting assembly can be used in laptops, tablets, and all-in-one computers, and the mounting component 4 can be used to fix hard drives, wireless network cards, etc. The circuit board body 3 is provided with a mounting bracket to fix the other side of the mounting component 4.

[0081] Since the circuit board mounting assembly includes the aforementioned non-removable retainer, it can achieve all its beneficial effects, which will not be elaborated further here.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this disclosure, "a plurality of" means two or more, unless otherwise explicitly specified.

[0083] The above are merely specific embodiments of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure.
