Description

Technical Field

[0001] This utility model relates to the field of circuit board technology, and in particular to a flexible circuit board that is easy to install. Background Technology

[0002] With the rapid development of electronic technology, various electronic products are placing increasingly higher demands on the integration of internal components and space utilization efficiency. Flexible printed circuit boards (FPCBs), as a key component of electronic products, bear the important functions of electrical connection and signal transmission. However, in actual production and assembly processes, existing FPCBs have revealed numerous problems in installation.

[0003] In the prior art, traditional circuit boards require screws to be used when mounting them to the substrate. However, this connection method has significant drawbacks, such as the need to fix the screws at the four corners of the circuit board, and the need to use tools for both installation and disassembly, making the installation process very inconvenient. Therefore, this utility model proposes a flexible circuit board that is easy to install, thus solving the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a flexible circuit board that is easy to install.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A flexible circuit board that is easy to install includes a substrate and a circuit board body. Two symmetrically arranged fixing plates are fixedly connected to the upper end of the substrate. Each of the two fixing plates has a groove at its upper end. Each of the two grooves is provided with a fixing mechanism for fixing the circuit board body. The fixing mechanism includes two symmetrically arranged sliders that are slidably connected in the groove. A U-shaped rod is fixedly connected to the opposite end of each of the two sliders. Four rectangularly distributed fixing blocks are fixedly connected to the lower end of the circuit board body. Each of the two fixing blocks on the same side has a notch at its opposite end that cooperates with the U-shaped rod.

[0007] Preferably, each of the four sliders has a sliding rod fixedly connected to its end.

[0008] Preferably, all four sliding rods pass through the sidewall of the fixed plate and are slidably connected to it.

[0009] Preferably, each of the four sliding rods has a handle fixedly connected to one end outside the fixed plate, and each of the four handles is covered with a protective sleeve.

[0010] Preferably, the sidewalls of the four handles are elastically connected to the sidewalls of the fixing plate by springs, and the four springs are respectively sleeved on the four sliding rods.

[0011] Preferably, the lower ends of the four fixing blocks are provided with inclined surfaces.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] 1. By setting up a fixing mechanism, during connection, the four fixing blocks at the lower end of the circuit board body are inserted into the sliding grooves on both sides. When the inclined surface at the lower end of the fixing block contacts the U-shaped rod, it squeezes the U-shaped rod and the slider to move outward, and stretches the spring to contract. When the U-shaped rod moves away from the inclined surface, under the action of the spring, the U-shaped rod inserts into the notch, thereby connecting and fixing the fixing blocks and the circuit board body. No bolts are needed for fixing, which can greatly improve the convenience of installation and disassembly.

[0014] 2. By setting up a fixing mechanism, after fixing, there is a certain gap between the substrate and the circuit board body, which makes the circuit board body more ventilated after installation, thereby improving the heat dissipation effect of the circuit board body and improving the practicality of the device.

[0021] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0022] Reference Figure 1-5 A flexible circuit board that is easy to install includes a substrate 2 and a circuit board body 1. Two symmetrically arranged fixing plates 3 are fixedly connected to the upper end of the substrate 2. Each of the two fixing plates 3 has a groove 302 at its upper end. Each of the two grooves 302 is provided with a fixing mechanism for fixing the circuit board body 1. The fixing mechanism includes two symmetrically arranged sliders 305 that are slidably connected in the grooves 302. A U-shaped rod 306 is fixedly connected to the opposite end of each of the two sliders 305. Four rectangularly distributed fixing blocks 4 are fixedly connected to the lower end of the circuit board body 1. Each of the two fixing blocks 4 on the same side has a notch 401 that cooperates with the U-shaped rod 306 at the opposite end.

[0023] Specifically, each of the four sliders 305 is fixedly connected to a sliding rod 304 at its end. Each of the four sliding rods 304 passes through the side wall of the fixed plate 3 and is slidably connected to it. Each of the four sliding rods 304 is fixedly connected to a handle 301 at the end outside the fixed plate 3. Each of the four handles 301 is fitted with a protective sleeve made of rubber. The side wall of each of the four handles 301 is elastically connected to the side wall of the fixed plate 3 by a spring 303. Each of the four springs 303 is fitted onto the four sliding rods 304.

[0024] Specifically, each of the four fixing blocks 4 has a slope 402 at its lower end. Under the action of the slope 402, the U-shaped rods 306 on both sides can be squeezed to move to both ends during installation, thus improving the ease of fixing.

[0025] When using this invention, during connection, the four fixing blocks 4 at the lower end of the circuit board body 1 are respectively inserted into the sliding grooves 302 on both sides. When the inclined surface 402 at the lower end of the fixing block 4 contacts the U-shaped rod 306, the U-shaped rod 306 and the slider 305 are squeezed outward, and the tension spring 303 is contracted. When the U-shaped rod 306 moves away from the inclined surface 402, under the action of the spring 303, the U-shaped rod 306 is inserted into the notch 401, thereby connecting and fixing the fixing blocks 4 and the circuit board body 1. No bolts are required for fixing, which greatly improves the convenience of installation and disassembly. After fixing, there is a certain gap between the substrate 2 and the circuit board body 1, which makes the ventilation effect of the circuit board body 1 better after installation, thereby improving the heat dissipation effect of the circuit board body 1.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
