[0002] When an electronic device (such as an M.2 solid-state drive) is connected and assembled to a circuit board, one end of the electronic device needs to be inserted into the connector provided on the circuit board to form electrical conduction, and the other end of the electronic device needs to be placed on the positioning post provided on the circuit board and screwed onto the positioning post by passing a screw through a hole in the circuit board. In this way, the other end of the electronic device is fastened to the circuit board, and finally the entire electronic device is stably assembled on the circuit board, ensuring that the electronic device and the circuit board form a stable electrical connection.

[0003] The above assembly method requires screw locking. Whether it is installation or removal, the screws need to be removed. The operation is cumbersome, the assembly speed is slow, and the efficiency is low. In addition, the screws are small in size, and the screws are easily lost during the assembly process, causing great trouble to the operator.

[0004] In view of this, the inventors propose the following technical solutions. Summary of the invention:

[0005] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a circuit board connection mechanism.

[0007] Furthermore, in the above technical solution, a handle is also provided on the outer side of the upper end of the rotating buckle.

[0008] Further, in the technical scheme, the rotating buckle is provided with a through hole at the upper end, and the fixing member is provided with a screw hole corresponding to the through hole. A screw is screwed into the screw hole through the through hole, and the rotating buckle rotates relative to the fixing member with the screw as the rotating shaft. The screw fixes the rotating buckle, the elastic element and the fixing member together to form an integral body which is detachably mounted on the circuit board.

[0009] Further, in the technical scheme, the rotating buckle is provided with a through hole at the upper end, and the fixing member is provided with a screw hole corresponding to the through hole. A screw is screwed into the screw hole through the through hole, and the rotating buckle rotates relative to the fixing member with the screw as the rotating shaft. The screw fixes the rotating buckle, the elastic element and the fixing member together to form an integral body which is detachably mounted on the circuit board.

[0010] Further, in the technical scheme, the elastic element is a torsion spring or a spring sheet.

[0011] Further, in the technical scheme, the elastic element includes an elastic body, an upper positioning portion formed on the upper end of the elastic body, and a lower positioning portion formed on the lower end of the elastic body. The elastic body is sleeved on the upper end of the fixing member, the lower positioning portion is arranged in the lower limiting hole of the fixing member, and the upper positioning portion is arranged in the upper limiting hole of the rotating buckle.

[0012] Further, in the technical scheme, the lower end of the fixing member is formed with a threaded column. A plurality of nuts are fixed on the circuit board in a row. The fixing member is screwed into any one of the nuts through the threaded column to be fixed on the circuit board.

[0013] Further, in the technical scheme, the nut is provided with a limiting groove on the periphery. The lower positioning portion of the elastic element extends out of the lower end surface of the fixing member through the lower limiting hole of the fixing member and can move up and down in the lower limiting hole. After the threaded column is screwed into the nut, the lower positioning portion is embedded in the limiting groove on the periphery of the nut.

[0014] Further, in the technical scheme, one side wall of the limiting groove is provided with an inclined guide surface.

[0015] Further, in the technical scheme, the unused nuts are pasted with a layer of Mylar, or the unused nuts are covered with a sealing cap. The lower end of the sealing cap is provided with symmetrically distributed first and second arc-shaped buckles and positioning columns located on the sides of the first and second arc-shaped buckles.

When the other end of the electronic device is pressed down to pass over the buckle body, the rotating buckle is realized by the torsional force of the elastic element. Automatic reset drives the buckle body to buckle and press on the upper end surface of the other end of the electronic device to lock the other end of the electronic device, thereby fixing the electronic device on the circuit board and forming stable electrical conduction. In addition, after directly pressing down the other end of the electronic device, the other end of the electronic device can be locked on the circuit board.

[0029] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0030] See Figure 1-9 As shown, a circuit board connection mechanism includes a circuit board 1, a connector 2, a fixing member 3, a rotating buckle 4 and an elastic element 5.

[0031] The connector 2 is fixed to the circuit board 1 and is used to connect to the electronic device 6, forming an electrical connection to enable stable data transmission. In this embodiment, the electronic device 6 is an M.2 solid-state drive. M.2 solid-state drives are solid-state drives with an M.2 interface. Due to their compact size and high-speed transmission performance, they are widely used on circuit boards. For example, most computers currently use M.2 solid-state drives.

[0032] The fixing member 3 is fixed on the circuit board 1 and can be removed relative to the circuit board 1; the rotating buckle 4 is rotatably installed on the upper end of the fixing member 3, and the elastic element 5 is arranged between the fixing member 3 and the rotating buckle 4, so that the rotating buckle 4 and the fixing member 3 form a stable assembly, and after the rotating buckle 4 rotates relative to the fixing member 3, the elastic element 5 will be compressed, and after the rotating buckle 4 is released, the rotating buckle 4 can be reset by the elastic element 5.

[0033] The outer side of the upper end of the rotating buckle 4 is provided with a buckle body 41 protruding outward, and the upper end of the buckle body 41 is provided with a guiding inclined surface 411; one end of the electronic device 6 is connected to the connector 2, and the other end of the electronic device 6 is pressed down, driving the other end of the electronic device 6 to press against the guiding inclined surface 411 of the buckle body 41, forcing the rotating buckle 4 to rotate relative to the fixing member 3 and compress the elastic element 5. When the other end of the electronic device 6 is pressed down to pass over the buckle body 41, the rotating buckle 4 is automatically reset by the torsion of the elastic element 5, driving the buckle body 41 to buckle on the upper end surface of the other end of the electronic device 6 to lock the other end of the electronic device 6, thereby fixing the electronic device 6 to the circuit board 1 and can form a stable electrical conduction. Moreover, the present invention can lock the other end of the electronic device 6 on the circuit board 1 after directly pressing down the other end of the electronic device 6. It is extremely convenient to operate and can be quickly replaced. The assembly efficiency is extremely high. There is no need to use tools such as screwdrivers to continuously remove screws as in the traditional method, which greatly shortens the operation time and makes the present invention highly competitive in the market.

[0034] The assembly method of the rotating buckle 4 and the fixing member 3 is as follows: the rotating buckle 4 is provided with a through hole 42 along its upper end downward, and the fixing member 3 is provided with a screw hole 31 corresponding to the through hole 42 at the upper end. A screw 7 is screwed through the through hole 42 and fixed in the screw hole 31, and the rotating buckle 4 rotates relative to the fixing member 3 with the screw 7 as the rotating axis, and the screw 7 fixes the rotating buckle 4, the elastic element 5 and the fixing member 3 together to form a whole. The whole is installed on the circuit board 1 in a detachable manner, thereby realizing the overall disassembly and assembly, which is more convenient to use. Among them, the upper end of the screw 7 is divided into a smooth rod and the lower end is divided into a thread, so that the smooth rod of the screw 7 is placed in the through hole 42, so that the rotating buckle 4 can rotate with the rotating buckle 4 as the axis, and the thread of the lower end of the screw 7 is screwed fixed to the screw hole 31, so that the screw 7 is fixed to the fixing member 3.

[0035] The elastic element 5 provides elastic force in the rotational direction between the rotating buckle 4 and the fixing member 3, so that the rotating buckle 4 and the fixing member 3 form a stable assembly, so that when performing a vibration test, the rotating buckle 4, the elastic element 5 and the fixing member 3 will not fall off.

[0036] In order to limit the rotation angle of the rotating buckle 4 relative to the fixing member 3, the following design is made: a travel limit groove 44 is provided at the lower end of the rotating buckle 4, and a slider 32 is provided at the upper end of the fixing member 3. The slider 32 is placed in the travel limit groove 44. The slider 32 can only move in the travel limit groove 44, thereby limiting the rotation angle of the rotating buckle 4 relative to the fixing member 3.

[0037] The upper outer side of the rotating buckle 4 is also provided with a handle 43. When it is necessary to unlock the electronic device 6 locked by the buckle body 41, the rotating buckle 4 can be rotated by simply pushing the handle 43 with a finger until the rotating buckle 4 is free of the other end of the electronic device 6. At this point, the other end of the electronic device 6 can be moved upward to clear the rotating buckle 4, thereby unlocking the electronic device 6. This operation is extremely convenient. After releasing the handle 43 of the rotating buckle 4, the rotating buckle 4 automatically resets due to the torsional force of the elastic element 5, preparing for the next locking.

[0038] The elastic element 5 includes an elastic body 51, an upper positioning portion 52 formed at the upper end of the elastic body 51, and a lower positioning portion 53 formed at the lower end of the elastic body 51. The elastic body 51 is sleeved on the upper end of the fixing member 3, and the lower positioning portion 53 is passed through the lower limit hole 34 provided in the fixing member 3, and the upper positioning portion 52 is passed through the upper limit hole 45 provided in the rotating buckle 4, so that the elastic element 5 is stably installed between the rotating buckle 4 and the fixing member 3.

[0039] In addition, the elastic element 5 can be a torsion spring or a spring. As a preferred embodiment of the present invention, the elastic element 5 is a torsion spring, which is more convenient to assemble.

[0040] A threaded column 35 is formed on the lower end of the fixing member 3 , and the fixing member 3 is screw-fixed to the circuit board 1 through the threaded column 35 , which makes assembly more convenient.

[0041] In order to prevent the threaded studs 35 of the fixing member 3 from damaging the circuit board 1 during assembly, the following design is made: a plurality of nuts 11 arranged in a row are fixed to the circuit board 1, and the fixing member 3 is screwed into any of the nuts 11 via the threaded studs 35, thereby achieving stable assembly without damaging the circuit board 1. Furthermore, since the plurality of nuts 11 arranged in a row are fixed to the circuit board 1, the distances between the nuts 11 and the connector 2 vary, making it suitable for locking electronic devices 6 of varying sizes. Specifically, for longer electronic devices 6, the nut 11 located farther from the connector 2 can be rotated and the threaded studs 35 of the fixing member 3 can be screwed onto the nut 11, thereby fastening the fixing member 3 and the rotating buckle 4 to the nut 11. Later, the rotating buckle 4 can be used to lock the electronic device 6. As a result, the present invention can lock electronic devices of varying sizes, has a wider range of applications, and is more convenient to use.

[0042] Furthermore, a limiting groove 111 is provided on the periphery of the nut 11. The lower positioning portion 53 of the elastic element 5 passes through the lower limiting hole 34 of the fixing member 3 to extend beyond the lower end surface of the fixing member 3 and is movable up and down within the lower limiting hole 34. Furthermore, after the threaded post 35 is screwed into position relative to the nut 11, the lower positioning portion 53 engages with the limiting groove 111 on the periphery of the nut 11. Specifically, only a small portion of the lower positioning portion 53 of the elastic element 5 extends beyond the lower end surface of the fixing member 3. Therefore, during the screwing process of the threaded post 35 relative to the nut 11, the lower positioning portion 53 engages with the limiting groove 111 on the periphery of the nut 11 only after the threaded post 35 is screwed into position. This ensures that the relative position of the buckle body 41 on the outer side of the upper end of the rotating buckle 4 is maintained. This ensures that the buckle body 41 is always in a position to block the depressed electronic device 6 under normal conditions, and that the electronic device 6 presses against the guide slope 411 of the buckle body 41 after being depressed.

[0043] The nut 11 is formed with a toothed portion 112 on its exterior, so that the user can easily install the nut 11 on the circuit board 1 using tools.

[0044] The unused nuts 11 on the circuit board 1 are covered by sealing caps 12, which can prevent foreign matter or dust from entering the interior of the nut 11 and seal the thread inside the nut 11. At the same time, the sealing cap 12 is also convenient for the robot to pick up.

[0045] The lower end of the sealing cap 12 is provided with a symmetrically distributed first arc-shaped buckle 121 and a second arc-shaped buckle 122 and a positioning column 123 located beside the first arc-shaped buckle 121 and the second arc-shaped buckle 122. The first arc-shaped buckle 121 and the second arc-shaped buckle 122 are buckled into the nut 11 and tightened to position, and the positioning column 123 is embedded in the limiting groove 111 set on the periphery of the nut 11, so as to ensure that the sealing cap 12 can be stably loaded on the nut 11 and can better protect the internal thread of the nut 11 and the external limiting groove 111.

[0046] Combine Figure 10-12 As shown, the present invention adopts another structure of the nut 11. Specifically, the outer portion of the nut 11 is no longer provided with a ring tooth portion 112. Instead, a pin 114 is bent at the rear side of the nut 11. When the nut 11 is installed in the mounting hole on the circuit board 1, the pin 114 is simultaneously embedded in the socket located next to the mounting hole on the circuit board 1, thereby fixing the nut 11 on the circuit board 1.

[0047] In addition, one side wall of the limiting groove 111 is configured as an inclined guide surface 113, so that when the nut 11 is unscrewed, the lower positioning portion 53 of the elastic element 5 will slide out along the inclined guide surface 113, making disassembly very convenient.

[0048] Furthermore, the unused nuts 11 may be coated with a layer of Mylar to achieve the same effect as the above-mentioned assembly of the sealing cap 12 .

[0049] In summary, the present invention provides an elastic element 5 between the rotating buckle 4 and the fixing member 3. The outer side of the upper end of the rotating buckle 4 is provided with a buckle body 41 protruding outward, and the upper end of the buckle body 41 is provided with a guide inclined surface 411. During use, one end of the electronic device 6 is connected to the connector 2, and the other end of the electronic device 6 is pressed down, driving the other end of the electronic device 6 to press against the guide inclined surface 411 of the buckle body 41, forcing the rotating buckle 4 to move relative to the fixing member 3. Rotate and compress the elastic element 5. When the other end of the electronic device 6 is pressed down to pass over the buckle body 41, the rotating buckle 4 is automatically reset by the torque of the elastic element 5, driving the buckle body 41 to buckle on the upper end surface of the other end of the electronic device 6 to lock the other end of the electronic device 6, thereby fixing the electronic device 6 on the circuit board 1 and forming a stable electrical conduction. In addition, the present invention can lock the other end of the electronic device 6 on the circuit board 1 after directly pressing down the other end of the electronic device 6. It is extremely convenient to operate and can be quickly replaced. The assembly efficiency is extremely high. There is no need to use tools such as screwdrivers to continuously remove screws as in the traditional method, which greatly shortens the operation time, making the present invention highly competitive in the market.

[0050] Of course, the above description is only a specific embodiment of the present invention and is not intended to limit the scope of implementation of the present invention. Any equivalent changes or modifications made based on the structure, features and principles described in the scope of the patent application of the present invention should be included in the scope of the patent application of the present invention.
