Description

A circuit board fixing structure

The present invention relates to the technical field of circuit board assembly, and in particular to a circuit board fixing structure.

A circuit board is a basic electronic component, usually a thin sheet with one or more layers of conductive material, such as copper, on it, which is used to connect and support electronic components to form a circuit. The main function of a circuit board is to provide electrical connections between electronic components and provide mechanical support. It is widely used in electronic devices, such as computers, mobile phones, and televisions. Among them, the motherboard is a special type of circuit board and a key component in a computer or other electronic device. The motherboard usually integrates key components such as the central processing unit (CPU), memory slots, graphics card slots, expansion slots, and input and output ports. The circuit board on the motherboard plays the role of connecting and supporting these components so that they can work together to form a complete system.

With the continuous development of computers, the performance and specifications of electronic components on motherboards are also constantly improving, and the requirements for heat dissipation of each component and the whole are increasing, which makes the size of CPU, graphics card, etc. continue to expand. In addition, the number of various interfaces, slots, control chips and heat dissipation modules on the motherboard is also increasing, resulting in some slots being blocked by other installed components, making it difficult for users to press and install the remaining components. Improper operation can easily damage the entire motherboard, and it cannot be released during disassembly, which is extremely inconvenient.

For example: a computer graphics card installation structure and a computer with Chinese patent application number 202010954846.4 discloses a more traditional card-mounting structure. The graphics card component is inserted into the slot 14 of the socket component through the connector 4, and the limit buckle 5 on the main control board 1 is locked by the buckle assembly in the card slot 15 on both sides of the slot 14 to realize the card-mounting of the graphics card. When disassembling, it is necessary to manually pull the pull pin 13 in the buckle assembly to disengage the card block 16 from the limit buckle 5 to achieve unlocking. Therefore, there needs to be enough space around the socket component for the hand to reach in to unlock the buckle component. For the current compact motherboard structure, the slot structure obviously cannot meet the needs, and cannot achieve the rapid disassembly and assembly of components such as graphics cards, and it is difficult to meet the parts replacement and maintenance of computer equipment.

The other end of the lock block 33 is provided with an elastic contact portion 332 that is bent upward and used to contact the limit buckle A1 in the display card component A.

The positioning cover 31 is provided with a plurality of positioning blocks 313 for positioning the pull plate 32, and the pull plate 32 is provided with a plurality of travel holes 323 for matching the positioning blocks 313 and being able to move. A first limiting plate 314 for installing and positioning one end of the pull plate 32 is provided at one end of the positioning cover 31, and a second limiting plate 315 for installing and positioning the other end of the pull plate 32, the button 35, and the positioning member 38 is provided at the other end of the positioning cover 31.

As shown in FIG. 12 and FIG. 13 , in another embodiment of the present invention, a locking plate 34 capable of pushing the locking buckle block 33 to lock is hingedly installed at one end of the positioning cover 31, and one end of the locking plate 34 is located below the locking buckle block 33 and in the groove 312. In one embodiment, the locking plate 34 located in the groove 312 is arranged at the front end of the positioning cover 31. The locking plate 34 can not only facilitate pushing the locking buckle block 33 to slide and lock quickly when locking, but also can push the limit buckle A1 of the display card component A out of the groove 312 when unlocking, thereby facilitating the removal of the display card component A. That is, when the limit buckle A1 of the display card component A is inserted into the groove portion 312, the limit buckle A1 pushes the upper locking plate 34 downward to swing, and the other end of the upper locking plate 34 pushes the lock block 33 to slide to the top of the limit buckle A1 to lock; when unlocking, the button 35 is pressed down to push the pull plate 32 to slide away from the slot 2, and the lock block 33 is pulled by the pull plate 32 to move away from the limit buckle A1. At the same time, the upper locking plate 34 swings under the pull of the pull plate 32, pushing the limit buckle A1 out of the slot 2, thereby facilitating the disassembly of the display card component A. The other end of the upper lock plate 34 extends and is buckled to the pull plate 32 and can move with the pull plate 32. One end of the pull plate 32 is bent and provided with a bent vertical plate 322 buckled with the upper lock plate 34 and the buckle block 33. The pull plate 32 is L-shaped, wherein one end of the pull plate 32 is buckled with the buckle block 33, the upper lock plate 34 and the buckle spring 37, and the other end of the pull plate 32 is bent and extends to the rear of the button 35.

In summary, when the present invention is used, the button 35 is first pushed up, and the release element 3 is in the unlocked state; further, the plug-in portion A2 of the display card element A is inserted into the slot 2, and during the insertion process of the display card element A, the limit buckle A1 of the display card element A will first contact the lock block 33 and push the lock block 33 back to compress the lock spring 37, and the limit buckle A1 will be completely inserted into the groove portion 312. After that, the lock spring 37 generates a reset thrust to push the lock block 33 to slide onto the limit buckle A1 and push the pull plate 32 to approach the slot 2, locking the limit buckle A1 and the display card component A. Of course, if an upper lock plate 34 is provided in the groove 312, after the limit buckle A1 is inserted into the groove 312, the upper lock plate 34 will be pushed to swing during the downward pressing process, and the lock block 33 is driven by the upper lock plate 34 to slide onto the limit buckle. A1 and push the pull plate 32 to move, so as to improve the locking efficiency, avoid the buckle spring 37 can not produce the restoring force in time and cause the locking to fail, or avoid the buckle spring 37 can not meet the pushing force of the buckle block 33 and fail to lock after long-term use, thereby improving the locking rate and service life; further, when it is necessary to release the graphics card component A, only need to press the button 35, and the button 35 pushes the pull plate 32 back Retract, and pull the lock block 33 back to unlock the limit buckle A1. At the same time, when the upper lock plate 34 is provided, the upper lock plate 34 will also be pulled to swing in the opposite direction to push the limit buckle A1 out. At this time, the buckle arm 381 of the clamping member 38 moves from the lower clamping groove 352B along the travel groove 352 to the upper clamping groove 352A, so that the button 35 remains pressed. At this time, the display card component A can be pulled out from the slot 2.

At the same time, when the button 35 is pressed, the locking member 38 keeps the button 35 in the pressed state through the locking arm 381 and limits the pull plate 32. If the display card component A is inserted into the slot 2 at this time, the limiting buckle A1 cannot be inserted into the groove portion 312, and the display card component A cannot be installed. Therefore, the state of the button 35 is used to indicate whether the release component 3 is in the locked state or the open state, thereby judging whether the display card component A is locked in place. When the display card component A needs to be installed again, the button 35 only needs to be pressed to move the snap arm 381 of the snap member 38 along the travel groove 352 to the lower snap groove 352B. At this time, the button 35 loses the limit element of the pull plate 32. When the display card component A is assembled, the limit buckle A1 can be smoothly inserted into the groove 312 and push the upper locking plate 34 to pull the pull plate 32 to move, thereby locking the display card component A.

Of course, the above 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 patent application scope of the present invention should be included in the patent application scope of the present invention.
