Description

Technical Field

[0001] The utility model relates to the technical field of flexible circuit boards, in particular to a flexible circuit board which is easy to install. Background Art

[0002] Flexible circuit board is a printed circuit made of flexible insulating substrate, which has the characteristics of high wiring density, light weight, thin thickness and good bending. Flexible circuit board, also known as "soft board", is a printed circuit made of flexible insulating substrate. Flexible circuit provides excellent electrical performance, can meet the design needs of smaller and higher density installation, and also helps to reduce assembly processes and enhance reliability. Flexible circuit board is the only solution to meet the requirements of miniaturization and mobility of electronic products.

[0003] The existing flexible circuit boards on the market do not have the function of being easy to install and disassemble, which reduces the efficiency of installation and disassembly of flexible circuit boards. At the same time, since the existing circuit boards are covered with a large number of precision components on the surface, if a large amount of dust accumulates, the performance of the circuit boards will be damaged. Therefore, in order to improve installation efficiency and strengthen product protection, we need to design a flexible circuit board that is easy to install to solve this problem.

[0004] After searching the application number CN202022689028.4, a flexible circuit board that is easy to install and disassemble is disclosed. The patent adopts the method of placing the circuit board on the top of the base, driving the screw rod to rotate through the forward and reverse motors, driving the screw rod to move the horizontal plate, driving the horizontal plate to move four L-shaped plates, driving the four L-shaped plates to move the two top plates, and driving the two top plates to move the two pressure plates, so that the two ends of the circuit board can be fixed. When the circuit board needs to be disassembled, it is only necessary to drive the top plate to drive the pressure plate to rise through the forward and reverse motors, so that the installation and disassembly of the circuit board is convenient and quick, thereby improving the efficiency of the installation and disassembly of the circuit board. The patent effectively improves the installation efficiency by means of a motor-driven device, but the document does not set a limit device, a heat dissipation device and a dust-proof device, and the consideration is not comprehensive enough. Because the motor generates heat during operation, if the ambient temperature is high or the equipment layout is not conducive to air circulation, the performance of the circuit board may be impaired. At the same time, if a dust-proof device is not set, dust is easily accumulated, resulting in the performance of the circuit board being impaired. Therefore, in view of this, the existing structure and defects are studied and improved, and a flexible circuit board that is easy to install is proposed. Utility Model Content

DETAILED DESCRIPTION

[0023] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0024] like Figure 1-Figure 3As shown, a flexible circuit board that is easy to install includes a base 1, the base 1 is fixed with a cover plate 2 through a side pin assembly 5, the guide legs 201 around the bottom of the cover plate 2 are installed with a fixing assembly 3, a flexible circuit board 4 is placed on the top of the base 1, the fixing assembly 3 includes a partition 303 fixed on the guide leg 201, a sliding rod 301 passes through the partition 303, the top rod head of the sliding rod 301 and the top of the partition 303 are connected with a spring A302, and the bottom end of the sliding rod 301 is fixed with a pressing plate 304.

[0025] As mentioned above, in actual use of this case, when the flexible circuit board 4 needs to be installed, it is only necessary to place the flexible circuit board 4 on the top of the base 1, and then place the cover plate 2 connected to the fixing component 3. During the placement process, the pressing plate 304 is first fitted with the flexible circuit board 4. When the cover plate 2 continues to move downward, the partition 303 slides downward on the slide rod 301 and stretches the spring A302. At this time, the pressing plate 304 is fixed above the flexible circuit board 4 through the rebound force of the spring A302, thereby fixing the two ends of the flexible circuit board 4. When the flexible circuit board 4 needs to be disassembled, it is only necessary to manually control the pull rope 503 in the side pin assembly 5, pull the limit block 501, and release the guide leg 201, thereby realizing the disassembly of the flexible circuit board 4, thereby improving the efficiency of installation and disassembly of the flexible circuit board 4, and protecting the flexible circuit board 4 from being damaged by pressing through limiting, reducing loss and extending service life.

[0026] Elastic blocks 305 are arranged in a matrix at the bottom of the pressure plate 304 of the fixing assembly 3 . The elastic blocks 305 are made of rubber and have a hemispherical appearance.

[0027] As mentioned above, when the guide legs 201 around the bottom of the cover plate 2 are fixed by the limit blocks 501 in the side pin assembly 5, the slide rod 301 will be driven to move downward, thereby driving the pressure plate 304 to move downward. Elastic blocks 305 are distributed in a matrix at the bottom of the pressure plate 304, so that the pressure plate 304 will not crush the flexible circuit board 4, thereby improving the protection effect of the flexible circuit board 4.

[0028] A side pin hole 202 is arranged on the outer side of the guide leg 201 of the cover plate 2 to fit with the side pin assembly 5. The side pin assembly 5 includes a spring B502 fixed on the base 1. A limiting block 501 is fixed on the other end of the spring B502. The top of the limiting block 501 fixed in the side pin assembly 5 is an arc-shaped structure. A pull rope 503 is arranged at the tail of the limiting block 501.

[0029] As mentioned above, a cover plate 2 connected to the fixing component 3 is placed, and side pin holes 202 are set on the outer sides of the guide legs 201 around the bottom of the cover plate 2. When the guide leg 201 is inserted into the insertion hole where the limit block 501 is located, the limit block 501 is first squeezed into the sliding recess. When the side pin hole 202 of the guide leg 201 corresponds to the position of the limit block 501, the rebound force of the spring B502 makes the limit block 501 pop out of the side pin hole 202 inserted into the guide leg 201, thereby limiting the position, preventing the flexible circuit board 4 from being damaged during the installation process. The top of the limit block 501 is an arc-shaped structure, which can make the side pin hole 202 better fit with the limit block 501 during the downward movement of the guide leg 201. A pull rope 503 is provided at the tail of the limit block 501, and the outer side of the pull rope 503 is covered with insulating material, which can facilitate the disassembly of the flexible circuit board 4 and increase the service life of the pull rope 503.

[0030] Two fans 7 are installed inside the base 1 , and the fans 7 are symmetrically installed at the bottom of the base 1 . Exhaust holes 101 are distributed in a matrix in the middle area of ​​the base 1 , and a dustproof screen 6 is installed on the bottom surface of the base 1 .

[0031] As mentioned above, before placing the base 1, after installing the fan 7, the dustproof mesh plate 6 is installed, which can achieve the effects of heat dissipation and dust prevention, thereby protecting the flexible circuit board 4 and increasing its service life. The middle area of ​​the base 1 is provided with exhaust holes 101 in a matrix distribution, which can also achieve the effect of heat dissipation and increase the service life of the flexible circuit board 4.

[0032] Working principle:

[0033] Before use, the fan 7 is installed inside the base 1, and then the dustproof screen 6 is installed at the bottom of the base 1. When in use, the flexible circuit board 4 is placed on the top of the base 1, and then the cover plate 2 connected to the fixing component 3 is placed. During the downward movement of the cover plate 2, the guide legs 201 around the bottom are fitted and fixed with the limit blocks 501 in the side pin component 5 to limit the position. During this process, the pressure plate 304 in the fixing component 3 will be fixed above the flexible circuit board 4, thereby achieving the effect of installing the flexible circuit board 4.
