Description

Technical Field

[0001] This utility model belongs to the field of circuit board auxiliary installation technology, specifically a circuit board with an auxiliary installation structure. Background Technology

[0002] A printed circuit board (PCB) is a circuit board made of insulating board as a substrate, cut to a certain size, with at least one conductive pattern on it and holes (such as component holes, mounting holes, metallized holes, etc.). It is used to replace the chassis of the past for mounting electronic components and to realize the interconnection between electronic components. It is an important electronic component, serving as the support for electronic components and the provider of electrical connections. Through specific design and manufacturing processes, it presents complex circuit systems in a graphical way. It is widely used in almost all electronic equipment fields such as computers, communications, consumer electronics, automotive electronics, and aerospace, and is an important foundation of the modern electronics industry.

[0003] For example, the utility model patent with announcement number CN222235315U discloses a circuit board with an auxiliary installation structure. This utility model includes a circuit board body, a mounting hole on the front side of the circuit board body, an auxiliary installation component on the inner wall of the mounting hole, and a protective component on the front side of the circuit board body. The auxiliary installation component includes a circular cylinder disposed on the inner wall of the mounting hole. This solves the problem that when installing a circuit board under the housing, workers need to lift the circuit board to ensure that the mounting holes on the circuit board are horizontally and vertically aligned with the mounting holes on the housing. Since workers need to tighten screws while lifting the circuit board, other mounting holes may shift off the mounting holes on the housing, requiring realignment and resulting in low installation efficiency.

[0004] However, during actual use, it was found that the overall structure of the device is complex, and the extension and contraction of the folding rod is achieved through the fold line. The expansion of the cylindrical tube is caused by the spring squeezing the folding rod. After repeated use, the fold line may experience metal fatigue due to frequent bending, resulting in deformation or breakage of the folding rod, which affects the normal expansion and contraction function of the cylindrical tube. The spring may also experience elastic decay or failure, causing the cylindrical tube to be unable to expand stably, making it difficult to achieve accurate positioning of the circuit board, and thus affecting the installation effect. Therefore, a circuit board with an auxiliary installation structure is provided. Utility Model Content

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] refer to Figures 1-4As shown, a circuit board with an auxiliary installation structure includes a housing base plate 1. A circuit board 2 is mounted on the top surface of the housing base plate 1. Multiple supporting connecting columns 3 are fixedly installed on the top surface of the housing base plate 1 near the corners, and each of the supporting connecting columns 3 has a threaded hole 4 on its top surface. Multiple mounting holes 5 corresponding to the supporting connecting columns 3 are provided on the top surface of the circuit board 2 near the corners. An auxiliary positioning installation mechanism 6 connected to the supporting connecting columns 3 is provided inside the mounting holes 5. The housing base plate 1 provides a stable mounting foundation for the circuit board 2. The supporting connecting columns 3 and threaded holes 4 provide connection points for fixing the circuit board 2. The mounting holes 5 correspond to the supporting connecting columns 3, facilitating the installation of the auxiliary positioning installation mechanism 6. The auxiliary positioning installation mechanism 6 enables fast and accurate installation positioning between the circuit board 2 and the housing base plate 1, improving installation efficiency and reducing installation errors compared to traditional installation methods.

[0022] refer to Figures 1-4 As shown, the auxiliary positioning and mounting mechanism 6 includes a hollow mounting rod 601, a connecting positioning block 602, a circular groove 603, a connecting through hole 604, a tapered limiting rod 605, and a cross bolt 606. The hollow mounting rod 601 is installed inside the mounting hole 5. A connecting fixing ring 7 is fixedly installed on the outer surface of the hollow mounting rod 601 near its top. The bottom surface of the connecting fixing ring 7 contacts the top surface of the circuit board 2. The connecting fixing ring 7 is made of silicone material, and its top surface near the side has an arc-shaped transition surface. The hollow mounting rod 601 serves as a carrier for the auxiliary positioning and mounting mechanism 6, facilitating connection and positioning. Components such as block 602 and cross bolt 606 provide a stable installation base. The connecting and fixing ring 7 on the outside is made of silicone. Through its elasticity and sealing properties, it can not only tightly fill the gap between the hollow mounting rod 601 and the mounting hole 5 of the circuit board 2, effectively preventing dust and impurities from entering, but also buffer external vibrations and protect the circuit board 2. During installation, the operator inserts the top of the hollow mounting rod 601 through the mounting hole 5 of the circuit board 2. The arc-shaped transition surface design on the top side of the connecting and fixing ring 7 makes the insertion process smoother. When the hollow mounting rod 601 is fully inserted, the bottom surface of the connecting and fixing ring 7 fits tightly against the top surface of the circuit board 2.

[0023] refer to Figures 1-4 As shown, a connecting positioning block 602 is fixedly installed at the bottom end of the hollow mounting rod 601, and a rubber pad 8 is fixedly installed on the top surface of the connecting positioning block 602. The top surface of the rubber pad 8 is in contact with the bottom surface of the circuit board 2. The connecting positioning block 602 enhances the connection stability between the hollow mounting rod 601 and the circuit board 2. The rubber pad 8 is elastic and can buffer and protect the circuit board 2 during installation, preventing the circuit board 2 from being directly and rigidly contacted with the connecting positioning block 602 and causing damage. At the same time, it increases the friction between the two and prevents the circuit board 2 from shifting after installation.

[0024] refer to Figures 1-4 As shown, a circular groove 603 is provided on the bottom surface of the connecting positioning block 602, and a connecting through hole 604 is provided on the top surface of the inner side of the circular groove 603. A conical limiting rod 605 is fixedly installed on the inner wall of the circular groove 603. Multiple conical limiting rods 605 are installed in a circumferential array on the inner wall of the circular groove 603, and the multiple conical limiting rods 605 are made of plastic material. The top of the supporting connecting column 3 is inserted into the inside of the circular groove 603. The circular groove 603 provides a space for the supporting connecting column 3 to be inserted, so as to achieve initial positioning. The conical limiting rods 605 are distributed in a circumferential array, which can limit the supporting connecting column 3 from multiple directions, prevent it from shaking in the circular groove 603, improve adaptability, and improve the stability of the circuit board 2 after installation. The plastic conical limiting rods 605 have a certain degree of flexibility, and will not damage the supporting connecting column 3 while limiting it.

[0025] refer to Figures 1-4 As shown, a cross bolt 606 is provided inside the hollow mounting rod 601. The inner diameter of the hollow mounting rod 601 and the connecting through hole 604 is larger than the outer diameter of the cross bolt 606. The bottom end of the cross bolt 606 passes through the interior of the connecting through hole 604 and is threadedly connected to the threaded hole 4. By providing the cross bolt 606 through the connecting through hole 604 and connecting to the threaded hole 4, it is easy to firmly fix the circuit board 2 to the housing base plate 1 and ensure the reliability of the connection. The inner diameter of the hollow mounting rod 601 and the connecting through hole 604 is larger than the outer diameter of the cross bolt 606, which provides operating space for the installation of the cross bolt 606 and facilitates installation and disassembly.

[0026] The implementation principle of this utility model of a circuit board with an auxiliary installation structure is as follows: When the circuit board 2 needs to be installed, the operator inserts the hollow installation rod 601 of the auxiliary positioning installation mechanism 6 into the installation hole 5 of the circuit board 2 from the bottom. At this time, the connecting fixing ring 7, through the elasticity of the silicone material and the arc transition surface design of the top side, makes the insertion process smooth. After the hollow installation rod 601 is fully in place, the bottom surface of the connecting fixing ring 7 is tightly attached to the top surface of the circuit board 2. At the same time, the rubber pad 8 on the connecting positioning block 602 contacts the bottom surface of the circuit board 2 to buffer the collision and increase the friction, ensuring that the hollow installation rod 601 is stable.

[0027] Subsequently, the personnel align one end of the circuit board 2 with the auxiliary positioning installation mechanism 6 installed with the support connecting column 3 of the housing base plate 1, so that the top of the support connecting column 3 is inserted into the circular groove 603 on the bottom surface of the connecting positioning block 602. The conical limiting rods 605 distributed in a circular array on the inner wall of the circular groove 603 contact the support connecting column 3 from multiple directions to increase friction and achieve the limiting effect, thus facilitating the initial positioning. Finally, the cross bolts 606 in the hollow mounting rod 601 are used to pass through the connecting through hole 604 and threadedly connect to the threaded hole 4 on the top surface of the support connecting column 3. After tightening, the circuit board 2 is firmly fixed on the housing base plate 1. Disassembly can be performed by reversing the operation. This device achieves convenient operation and accurate positioning of the circuit board through its simple structure, which can effectively improve the installation efficiency and stability of the circuit board.
