Description

Technical Field

[0001] This utility model relates to the field of circuit board technology, and in particular to a fixable circuit board. Background Technology

[0002] As a core component of electronic devices, circuit boards are widely used in communications, home appliances, industrial control and other fields. The stability of their installation and fixation directly affects the overall performance and service life of electronic devices. In practical applications, circuit boards need to be fixedly connected to the equipment housing or mounting frame through a specific structure to avoid displacement of the circuit board or detachment of components due to external forces such as vibration and impact, and to ensure the reliability of circuit connections.

[0003] The most common method for fixing circuit boards is to directly fasten them with screws. This method requires precise positioning of the circuit board during installation, which results in low installation efficiency. When the existing fixing structure clamps and fixes the circuit board, the rigid contact often causes excessive local stress on the circuit board, which can easily damage the substrate or surface components. To solve the above problems, this application proposes a fixable circuit board. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a fixable circuit board. The circuit board achieves rapid connection between the substrate and the mounting carrier through a disassembly and assembly mechanism, eliminating the need for complex positioning operations. The buffer component in the disassembly and assembly mechanism can prevent direct compression of the substrate by rigid contact during the pressing and fixing process, reducing the risk of substrate deformation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A fixable circuit board includes a substrate, a mounting plate at the bottom of the substrate, and four disassembly / reassembly mechanisms between the substrate and the mounting plate. Each disassembly / reassembly mechanism includes a column fixedly connected to the top of the mounting plate, the column extending through the substrate, a threaded sleeve threadedly connected to the outer wall of the column, two handles fixedly connected to the outer wall of the threaded sleeve, a rubber pad at the bottom of the threaded sleeve, resistors, capacitors, inductors, potentiometers, transformers, transistors, and diodes fixedly connected to the front of the substrate, multiple terminals fixedly connected to the front of the substrate, and multiple plugs mounted on the front of the substrate.

[0006] Preferably, the substrate has four through holes, and the four pillars are arranged through the corresponding through holes.

[0007] Preferably, the outer wall of the column is provided with an external thread, and the inner wall of the threaded sleeve is provided with an internal thread that mates with the external thread.

[0008] Preferably, the two ends of the rubber pad are arranged to abut against the top of the substrate and the bottom of the threaded sleeve, respectively.

[0009] Preferably, the number of terminals is set to multiple and arranged adjacent to each other.

[0010] Preferably, the number of plugs is set to multiple.

[0011] Compared with the prior art, the advantages of this utility model are as follows: 1. The circuit board achieves rapid connection between the substrate and the mounting carrier through a specific disassembly and assembly mechanism, eliminating the need for complex positioning operations. Workers can complete the fixing with simple operations, greatly reducing installation steps, lowering the difficulty of operation, and significantly improving installation efficiency.

[0012] 2. The assembly and disassembly mechanism uses threaded connections to press and fix the substrate, and the positioning structure ensures that the substrate is not easily displaced after installation.

[0013] 3. The buffer components in the assembly and disassembly mechanism can prevent direct compression of the substrate by rigid contact during the clamping and fixing process, thereby reducing the risk of substrate deformation.

[0014] In summary, the circuit board achieves rapid connection between the substrate and the mounting carrier through the disassembly and assembly mechanism, eliminating the need for complex positioning operations. The buffer component in the disassembly and assembly mechanism can prevent direct compression of the substrate by rigid contact during the clamping and fixing process, reducing the risk of substrate deformation.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figures 1-3A fixed circuit board includes a substrate 1, which serves as the main structure of the circuit board and is used to support various electronic components and provide a circuit connection base. A mounting plate 2 is provided at the bottom of the substrate 1. The mounting plate 2 is part of the housing and provides a mounting support base for the substrate 1, thereby achieving overall fixed support of the circuit board. Four disassembly and assembly mechanisms are provided between the substrate 1 and the mounting plate 2. The disassembly and assembly mechanisms are used to realize the detachable connection between the substrate 1 and the mounting plate 2, which facilitates the installation and maintenance of the circuit board.

[0019] The disassembly and assembly mechanism includes a column 4 fixedly connected to the top of the mounting plate 2. The column 4 provides a support carrier for the positioning and fixing of the base plate 1. The column 4 is arranged through the base plate 1. Four through holes 3 are provided through the base plate 1. The through holes 3 provide a through channel for the column 4 to ensure that the column 4 can pass through the base plate 1 to achieve positioning. The four columns 4 are arranged through the corresponding through holes 3 respectively.

[0020] The outer wall of the column 4 is fitted with a threaded sleeve 5 that is threadedly connected to it. The threaded sleeve 5 achieves the pressing and fixing of the substrate 1 through the threaded engagement with the column 4. The outer wall of the column 4 has an external thread, and the inner wall of the threaded sleeve 5 has an internal thread that engages with the external thread. The engagement of the internal and external threads allows the threaded sleeve 5 to move axially along the column 4 to adjust the pressing degree on the substrate 1. Two handles 6 are fixedly connected to the outer wall of the threaded sleeve 5. The handles 6 make it easy for the operator to hold and rotate the threaded sleeve 5, reducing the difficulty of operation. A rubber pad 7 is provided at the bottom of the threaded sleeve 5. The rubber pad 7 can deform and acts as a buffer between the threaded sleeve 5 and the substrate 1 to prevent the threaded sleeve 5 from directly squeezing and damaging the substrate 1. The two ends of the rubber pad 7 are respectively arranged to abut against the top of the substrate 1 and the bottom of the threaded sleeve 5.

[0021] The front side of substrate 1 is fixedly connected to a resistor 8, which limits the current in the circuit; a capacitor 9, which stores charge and regulates the voltage in the circuit; an inductor 10, which impedes changes in current and serves as a filter and energy storage device; a potentiometer 11, which can adjust its resistance value to regulate circuit parameters; a transformer 12, which changes the voltage level in the circuit to raise or lower the voltage; a transistor 13, which amplifies electrical signals or acts as a switch to control the on / off state of the circuit; and a diode 14, which has unidirectional conductivity and is used for rectification or to prevent reverse current flow. The front side of substrate 1 is also fixedly connected to multiple terminals 15, which are used to achieve electrical connections between external wires and the circuit board. Multiple terminals 15 are arranged adjacent to each other. The front side of substrate 1 is also equipped with multiple plugs 16, which are used for quick connection between the circuit board and external devices to achieve signal or power transmission. Multiple plugs 16 are also present.

[0022] In this utility model, the worker places the substrate 1 on the mounting plate 2, so that the four columns 4 pass through the corresponding through holes 3 respectively. The worker then places the rubber pad 7 on the top of the substrate 1, and the worker holds the threaded sleeve 5 and rotates it so that it rotates and moves down until the bottom of the threaded sleeve 5 abuts against the top of the rubber pad 7, thus completing the abutment and fixation of the four corners of the substrate 1 and completing the installation and fixation of the substrate 1.
