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 splice. Background Art

[0002] Medical electronic components provide strong support and guarantee for medical electronic equipment, making medical work more efficient and accurate. In the process of using medical electronic components, flexible circuit boards are needed. Flexible circuit boards are a printed circuit made of flexible insulating substrates. Flexible circuit boards have excellent electrical properties and high flexibility. The emergence of flexible circuit boards has greatly promoted the miniaturization and high density of electronic products.

[0003] The existing flexible circuit boards have certain defects during use. The main reason is that it is relatively troublesome to splice two flexible circuit boards because the material itself is highly flexible and bendable, so its shape and position need to be more accurately controlled during splicing, which requires a lot of energy and time in the process of splicing. Therefore, the technicians in this field provide a flexible circuit board that is easy to splice to solve the problems raised in the above background technology. Utility Model Content

[0004] The utility model aims to solve the shortcomings of the prior art and proposes a flexible circuit board that is easy to splice. Through the cooperation of a rectangular groove in a fixing block and special-shaped springs fixedly connected at the upper and lower ends of the inserting block, two flexible circuit boards can be spliced ​​together, thereby improving the splicing efficiency.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a flexible circuit board that is easy to splice, including a blood pressure measuring meter panel module, two flexible circuit board modules are fixedly connected inside the blood pressure measuring meter panel module, and the outer surfaces of the two flexible circuit board modules are fixedly connected with protective coatings all around, and the two flexible circuit board modules include a flexible circuit board body, one side surface of one of the two flexible circuit board bodies is fixedly connected with a fixed block, and the other side surface of the two flexible circuit board bodies is fixedly connected with an insertion block, and the upper and lower end surfaces of the inner wall of the fixing block are provided with rectangular grooves, and the upper and lower end surfaces of one side of the insertion block near the center are fixedly connected with special-shaped springs, and the upper end surfaces of multiple special-shaped springs are fixedly connected with connecting rods, and the one side surfaces of multiple connecting rods are fixedly connected with pressing rods;

[0006] The protective coating includes a copper cladding layer, the upper surface of the copper cladding layer is fixedly connected to a solder resist layer, the upper surface of the solder resist layer is fixedly connected to a gold plating layer, the upper surface of the gold plating layer is fixedly connected to a three-proof paint, and the upper surface of the three-proof paint is fixedly connected to a nano coating.

[0007] Through the above technical solution, because the two flexible circuit board bodies are clamped together by the fixing block and the plug-in block, the two flexible circuit boards are clamped together by inserting the special-shaped springs fixedly connected to the surfaces of the upper and lower ends of the plug-in block into the rectangular grooves. If necessary, when the fixing block and the plug-in block are separated, the special-shaped springs are deformed by pressing the pressing rod, so that the special-shaped springs cannot resist the rectangular grooves at the upper and lower ends of the inner wall of the fixing block. In this way, the two are conveniently disassembled. Therefore, the fixing block and the plug-in block are clamped and pressed to splice the two flexible circuit boards, and A protective coating is fixedly connected around the surface of the flexible circuit board body. The copper cladding layer in the protective coating can improve the conductivity of the flexible circuit board body, reduce the ground line impedance, and thus improve its anti-interference ability. The solder mask can protect the flexible circuit board body from moisture and isolation. The gold-plated layer can effectively prevent the lead or copper in the circuit board from reacting with each other, thereby protecting the circuit. The three-proof paint can further achieve a moisture-proof effect, thereby extending the service life of the flexible circuit board body. Finally, the nano coating can provide an additional protective layer.

[0008] Furthermore, the blood pressure measuring meter panel module comprises a blood pressure measuring meter panel body, and a measuring plate is fixedly connected to the upper end surface of the blood pressure measuring meter panel body;

[0009] Through the above technical solution, the patient's blood pressure can be measured through the measurement plate in the main body of the blood pressure measuring meter panel.

[0010] Furthermore, a plurality of copper foils are fixedly connected to the upper end surfaces of the two flexible circuit board bodies, and a plurality of conductive circuits are fixedly connected to the upper end surfaces of the two flexible circuit board bodies;

[0011] Through the above technical solution, the main function of copper foil is to conduct current and shield signals, and it can also play a role in signal transmission and optimize spatial layout under the function of conductive lines.

[0012] Furthermore, a center hole is provided on the rear side surface of the upper ends of the two flexible circuit board bodies near the center;

[0013] Through the above technical solution, the main function of the center hole is to be used for electrical connection, relieve current pressure and heat dissipation.

[0014] Furthermore, the main material of the copper cladding layer is conductive copper, and the main material of the solder resist layer is epoxy resin;

[0015] Through the above technical solution, the conductive copper in the copper cladding layer can improve the conductive performance, and the solder resist layer can protect the circuit board and prevent solder slag from contaminating the outer layer.

[0016] Furthermore, the main material of the gold-plated layer is gold material, the main materials of the three-proof paint are resin, solvent and pigment, and the main material of the nano coating is nanoparticles;

[0017] Through the above technical solution, the circuit board can be protected from corrosion and its conductivity can be enhanced by the action of the gold-plated layer, the service life can be extended by the action of the triple-proof paint, and the flexible circuit board can be provided with additional protection by the action of the nano-coating.

[0018] Furthermore, the inner walls on both sides of the fixed block are provided with sliding grooves, and the surfaces on both sides of the plug block are fixedly connected with sliding blocks;

[0019] Through the above technical solution, the fixed block and the inserting block are clamped together by the cooperation between the sliding groove and the sliding block.

[0020] The utility model has the following beneficial effects:

[0021] 1. The utility model provides a flexible circuit board that is easy to splice. When two flexible circuit boards need to be spliced, an insert block on one side of the main body of one flexible circuit board is inserted into a fixed block on one side of the main body of another flexible circuit board. When the insert block is inserted into the fixed block, the special-shaped springs at the upper and lower ends of the insert block are deformed by being squeezed at the beginning, and then return to their original state when they come into contact with the rectangular groove. In this way, it is not only convenient to splice the two together, but also because the special-shaped springs can block the insert block inserted into the fixed block under the action of the special-shaped springs, so that the two will not be easily separated, thereby improving the connection strength of the two flexible circuit boards.

[0022] 2. The utility model proposes a flexible circuit board that is easy to splice. The protective coating is fixedly connected around the surfaces of two flexible circuit boards. The copper cladding layer in the protective coating can enhance the conductive performance and improve the anti-interference ability of the flexible circuit board body. The solder resist layer in the protective coating can provide moisture-proof and isolation effects on the flexible circuit board body. The gold-plated layer can effectively prevent the reaction between lead or copper in the circuit board. The three-proof paint can further provide moisture-proof effects. Finally, the nano coating can provide additional protection for the flexible circuit board body. BRIEF DESCRIPTION OF THE DRAWINGS
