Description of the Invention: [Technical Field] [0001] The present invention relates to an electronic device, and more particularly to an electronic device having a circuit board. [Prior Art] [0002] With the continuous advancement and development of technology, electronic devices such as computers and mobile phones have become an indispensable part of modern life. A circuit board is one of the most important parts of such electronic devices. It is mainly used to connect electronic components and wafers to achieve the desired functions. The assembly method of the conventional circuit board is roughly based on the re-education of 'returning the main board lock'. The teeth are on the casing of the electronic device. [0003] A locking mechanism for a circuit board, comprising a plurality of screws and corresponding plurality of pillars. The pillar is located between the circuit board and the casing to maintain the height between the circuit board and the casing. The struts are hollow and have internally threaded holes. When assembling the main board on the casing, firstly, the respective pillars must be separately divided into the holes reserved in the casing, and then the screws are inserted into the mounting holes of the circuit board and locked in the pillars. Then fix the motherboard to the chassis. [0004] However, because of the machining accuracy or other reasons, the threaded holes in the pillars are not completely aligned with the mounting holes of the circuit board, and the screws are rotationally locked into the pillars at an oblique angle. At this time, the screw head may be damaged by the board, and the board is damaged to affect the operation of the board, and even the assembly hole is cracked, so that the fixing effect is lost. [0005] 099100449 [Summary of the Invention] In view of this, there must be a form number A0101 to provide a kind of prevention of board assembly when the 4th/18th page is broken. 201125473 [0006] Ο [0007] ❹ [0008] [0009 ] 099100449 electronic device. An electronic device 'includes a housing, a circuit board located inside the housing, and a fixed structure. Mounting holes are formed on the circuit board. The fixing structure includes a screw, a locking member, and a connector provided on the housing. The screw secures the circuit board to the connector. A threaded hole is formed in the locking member to cooperate with the screw. The connector includes a top portion that abuts the circuit board, and a receiving cavity formed in the top portion for receiving the locking member. A positioning hole communicating with the accommodating cavity is further formed on the top portion, and the hole of the positioning hole is larger than the diameter of the screw. The locking member slides in the accommodating cavity to adjust the relative position of the threaded hole and the mounting hole of the circuit board. The screw passes through the mounting hole and the positioning hole and is locked to the threaded hole of the locking member. The screw of the electronic device can sequentially pass through the mounting hole and the positioning hole to enter the threaded hole, thereby fixing the circuit board to the housing through the connecting member. When the positioning hole of the connecting component is not aligned with the mounting hole of the circuit board, the locking component can slide in the accommodating cavity of the connecting component, thereby adjusting the position of the screw entering the locking component, preventing the screw from being squeezed at an abnormal angle. The board causes damage. [Embodiment] Hereinafter, the electronic device of the present invention will be further described in detail with reference to the accompanying drawings and embodiments.

The first abutting surface 5541 is. ^The spherical surface, the second abutting surface 5542 is a plane. One of the two convex 521 ridges 5523, the two opposite sides of the two detachable plates and the second abutting surface 5542 of the top 554 collectively form a receiving cavity 556 for receiving the locking member 53. The minimum width of the accommodating cavity (4) (ie, the vertical spacing of the two slabs (10)) is greater than the distance between the opposite sides 535 of the locking member 53 (ie, the corner of the square bottom surface 533 to the minimum distance of the opposite side), but less than the lock The length of the diagonal of the square bottom surface 533 of the fitting member 53 (i.e., the angle from the corner of the square bottom surface 533 to the center of the bottom surface 533, the south of the distance), whereby the locking member 53 can be partially spherical within the receiving cavity 556. The support surface 5523 slides but is limited to a free rotation in the accommodating cavity 556 that does not exceed 360 degrees around the axis of the thread 5:32. The top portion 554 further defines a positioning hole 555 communicating with the accommodating cavity 556 on the first abutting surface 5541. The aperture of the positioning hole 555 is smaller than the aperture of the mounting hole 31 of the circuit board 30, and the aperture of the positioning hole 555 is larger than the diameter of the threaded rod 513 of the screw 51. Referring to FIG. 4 'Assembling, the fixing portion 5 of the connecting member 5 is firstly assembled. 5 3 is completely attached to the bottom surface 11 of the casing 10 by a double-sided tape. The locking member 53 is then placed into the receiving cavity 556 from one side of the connecting member 55 and the locking member 53 is located at a central position of the receiving cavity 556. The circuit board 3 is placed on the connector 55 in a direction perpendicular to the connector 55, and the mounting holes 31 of the circuit board 30 are coaxially aligned with the positioning holes 555 of the connector 55. The threaded rod 513 of the screw 51 passes through the mounting hole 31 and the positioning hole 555 in sequence to be locked to the threaded hole 532 of the locking member 53, thereby fixing the circuit board 30 to the housing 1. When the screw 51 is screwed into the locking member At 53 o'clock, the locking member 53 performs a rotation of less than 90 degrees with respect to the accommodating cavity 556, and the width of the accommodating cavity 556 is smaller than that of the locking member 53 by 099100449, the form number Α0101, the seventh page/the total 18 page, 0992000992-0, 201125473. The length of the diagonal line of the bottom surface 533, so that when the opposite angles of the bottom surface 533 of the locking member 53 simultaneously abut against the two side walls of the accommodating cavity 556, the locking member 53 stops rotating to make the threaded rod 513 of the screw 51 smooth. Enter the threaded hole 532. After the locking is completed, the head 511 of the screw 51 abuts against the top surface of the circuit board 30; the first abutting surface 5541 of the connecting member 55 abuts against the bottom surface of the circuit board 30 near the mounting hole 31; the locking member 53 The top surface 531 abuts against a portion of the second abutting surface 5542 of the connecting member 55 that is adjacent to the positioning hole 555. [0016] 099100449 ° month Referring to FIG. 5 'When the fixing portion 553 of the connecting member 55 and the bottom surface 11 of the housing 10 cannot completely overlap due to the processing accuracy or the assembly is not in place, etc., the extension of the connecting member 55 The direction may not be perpendicular to the board 3, and the mounting holes 31 of the board 3 and the positioning holes 555 of the connector 55 may not be coaxially aligned. When the threaded rod 513 of the screw 51 passes through the fitting hole 31 and the positioning hole 555 in sequence, the threaded hole 532 of the lock member 53 may not be located directly below the thread filial 513. At this time, since the distance between the opposite sides 535 of the locking member 53 is smaller than the width of the accommodating cavity 556, and the diameter of the positioning hole is larger than the diameter of the thread #513, the locking member 53 can be from the middle position of the accommodating cavity 556. The spherical support surface 5523 slides to a position close to the side of the accommodating cavity 556' to keep the threaded hole 532 coaxially aligned with the fitting hole 31. It is still possible to smoothly enter the threaded hole 532 in the direction perpendicular to the circuit board 3 由 by the Ding Zhiluo 1 rod 51 3 to fix the circuit board to the casing 10. After the lock is completed, the bottom surface of the head 511 of the screw 51 and the top surface of the circuit board 3D are completely heavy and the contact area is large. The circuit board 3G is relatively uniform in force and is not easily damaged. After the assembly is completed, the brother of the Du Qiang member 55 is attached to the face 5541 and the circuit board 30. Form number Α 0101 Page 8 / Total 18 pages 0992000992-0 [0017] 201125473 The bottom sin is close to the part of the assembly hole 31. Since the first abutting surface 5541 is partially spherical, the first abutting surface 5541 and the contact surface of the bottom surface of the circuit board 3 can be connected in a circle, thereby preventing the circuit board 30 from being deformed due to excessive stress. In addition, the top surface 531 of the locking member 53 abuts against the portion of the second resisting surface 5542 of the connecting member which is close to the positioning hole 555. Similarly, since the top surface 531 of the locking member 53 is a partially spherical surface, it is possible to prevent the stress of the connecting member 55 from being excessively concentrated on the locking member 53 and cause the locking member 53 to be deformed. [0018] 可 [0019] Comprehensible The shape of the bottom surface 533 of the locking member 53 may also be a regular polygon such as an equilateral triangle, a regular pentagon or a regular hexagon. Ο A support plate 552 may not be parallel to each other, and the minimum width of the accommodating cavity 556 at this time should be greater than a minimum distance from one corner of the regular polygon to the side opposite to the angle, and less than the angle from the corner to the center of the regular polygon. Doubled. If the second abutting surface 5542 or the supporting surface 5523 forming the valley chamber 556 is formed with a protrusion for blocking the rotation of the locking member 53 about its own axis, the minimum width of the determining chamber 556 may be greater than the angle to the regular polygon. Double the distance of the center. If the locking member 53 is formed with a protrusion that can abut against the side wall of the accommodating 556 to prevent it from rotating 360 degrees, the shape of the bottom surface 533 of the locking member 53 may not be a regular polygon, such as an isosceles triangle or a circle. Or oval. [0020] The top surface 531 of the locking member 53 and the first abutting surface 5541 of the connecting member 55 are not limited to being partially spherical, and may be, for example, curved or parabolic.
