Detailed Description
To make the objects, features and advantages of the present invention more obvious and understandable, the embodiments of the present invention will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention, and obviously, the described embodiments are only some embodiments, not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative efforts all belong to the protection scope of the present invention.
As shown in fig. 1 and fig. 2, the circuit board provided by the present invention includes a strip-shaped board body 1, wherein the board body 1 is provided with a connector 2, an electronic component 3 and a protection component 4; the connector 2 comprises a plugging end for connecting a wire row, and the plugging direction of the wire row is vertical to the length direction of the plate body 1; along the length direction of the plate body 1, the electronic element 3 is arranged on one side or two sides of the connector 2; the board body 1 is far away from the limit of grafting end and is first long limit 5, and protection component 4 is located between first long limit 5 and connector 2 to the linear distance of protection component 4 apart from first long limit 5 is less than the linear distance of electronic component 3 apart from first long limit 5.
When the screen occupation ratio and the narrow edge of the display screen are increased, the circuit board connected with the display screen is generally in a strip shape, and the smaller the area of the circuit board in the strip shape is, the more the screen occupation ratio of the display device is favorably improved. During plug connector, the easy atress deformation of first long limit 5 of circuit board leads to partial circuit board direct and display device contact promptly after the deformation, and the condition that a part or damage appears probably leading to the components and parts on the circuit board in the contact part. Since the main stressed position in the circuit board is the connector 2, the deformation position of the circuit board is generally in the vicinity of the connector 2. Therefore, the protection element 4 is arranged in the area between the first long side 5 and the connector 2, and the protection element 4 is arranged closer to the first long side 5 in order to avoid that components on the circuit board come into contact with the display device before the protection element 4.
In some embodiments, when the circuit board is deformed, the circuit board may be deformed along a plane where the circuit board is located, and may also be deformed along a height direction of the circuit board, so as to avoid damage to components caused by the deformation in the height direction, the height of the protection element 4 is greater than or equal to the height of the electronic element 3 and less than the height of the connector 2, that is, after the circuit board is deformed in the height direction, because the protection element 4 is relatively high, when the circuit board touches the display device, the protection element 4 contacts the display device first.
For example, the linear distance of the protective element 4 from the first long side 5 is closer to 0.2mm than the linear distance of the electronic element 3 from the first long side 5. For example, the protective element 4 has no electrical function. For example, the thickness of the protective element 4 ranges from 0.5mm to 0.7 mm.
In some embodiments, a plurality of electronic components 3 may be disposed on one side of the connector 2, and may also be disposed on both sides of the connector 2, and when the protection components 4 are disposed, the number and positions of the protection components 4 may be determined according to the relative positions of the electronic components 3 and the connector 2.
For example, the electronic component 3 is provided on one side of the connector 2 along the length direction of the board body 1; between the first long side 5 and the connector 2 is a mounting area for the protective element 4, which mounting area is provided with the protective element 4 near one end of the electronic component 3. One protective element 4 is arranged on the circuit board, or a plurality of protective elements 4 are arranged near the area where the protective elements 4 are located. A plurality of electronic components 3 are provided on the connector 2 side, and the electronic component 3 closest to the first long side 5 among the plurality of electronic components 3 is a protected component 4. In general, the protected element 4 is disposed near the protection element 4 among the plurality of electronic elements 3.
For example, the electronic components 3 are provided on both sides of the connector 2 along the length direction of the board body 1; between the first long side 5 and the connector 2 is a mounting area for the protection element 4, which mounting area is provided with the protection element 4 near both ends of the electronic component 3, respectively. When the circuit board is deformed, the electronic elements 3 closest to the display device are located on both sides of the circuit board, that is, the protected elements 4 are located on both sides of the circuit board, so that the protection elements 4 are respectively arranged on both ends of the mounting area, and the protection elements 4 respectively protect the protected elements 4 on the same side.
In some embodiments, Surface Mount Technology (SMT) is a necessary process in the circuit board manufacturing process, and thus, the protection element 4 may be mounted simultaneously during the SMT mounting process.
For example, pad points are added at the mounting position of the protection element 4 on the circuit board, and the protection element 4 and the pad points are welded during the SMT process of the circuit board. The SMT chip mounting process is adopted to replace the complex dispensing process and PCBA transfer, and the method has the advantages of being simple in manufacturing process and low in cost.
In some embodiments, the protection element 4 has a rectangular parallelepiped shape. The protective element 4 has a long side which abuts against the display device when the circuit board is deformed. The long edge has a certain abutting distance, which is beneficial to the stability of protection.
In some embodiments, in display devices of different display sizes, it is desirable to fit circuit boards of different sizes. For example, 15-inch display devices and 17-inch display devices use circuit boards of different sizes. For example, the plate body 1 has a rectangular parallelepiped shape, and the length ranges thereof are: 100mm to 400mm, width range: 4mm to 20 mm.
As shown in fig. 3, another aspect of the present invention provides a display structure, which includes a display device 6 and the circuit board; the first long side 5 of the circuit board is connected to a display device 6. The circuit board is arranged on one side of the display device 6, and two ends of the first long edge 5 of the circuit board are fixedly connected with the display device 6.
The two ends of the first long edge 5 of the circuit board are provided with the connecting structures, when the connector 2 is plugged in and pulled out, the two ends of the first long edge 5 of the circuit board are not easy to deform under the support of the connecting structures, and the two connecting structures are easy to deform. As shown in fig. 3, if the circuit board is deformed, the protection element 4 abuts against the display device 6, thereby functioning as a protection support.
The embodiment of the utility model provides a circuit board and display structure, set up protection component 4 on the circuit board, can carry out the activity spacing to the plug application of force region through protection component 4, prevent the damage of plug process to the circuit board; in addition, the protection element 4 can be formed in the Surface Mount Technology (SMT) process of the circuit board, and the manufacturing process of the protection element 4 is simple and low in cost.
