Description

Technical Field

[0001] This utility model belongs to the field of circuit board technology, specifically relating to a stable connection circuit board. Background Technology

[0002] With the rapid development of electronic information technology, circuit boards, as core components of electronic devices, directly affect the performance and lifespan of equipment due to their installation stability, maintainability, and applicability. In aerospace, industrial automation, and automotive electronics, the operating environment is complex and variable, with frequent vibrations and shocks, placing extremely high demands on the installation reliability of circuit boards. Meanwhile, in consumer electronics and communication base stations, rapid equipment updates and high maintenance requirements necessitate more convenient and efficient circuit board installation solutions. However, currently widely used traditional circuit board installation technologies have many limitations and struggle to meet the industry's growing needs.

[0003] Regarding installation stability, traditional circuit boards mostly rely on screws or clips for fixing. While screw fixing provides a certain degree of tightening force, under long-term vibration, screws are prone to loosening, causing the circuit board to shift and leading to faults such as short circuits and poor contact. Traditional circuit board mounting structures are mostly integrated designs, and when a component is damaged, the entire board often needs to be disassembled and replaced, increasing maintenance costs. In addition, screws and clips are prone to stripping and wear after repeated disassembly and assembly, leading to connection failure and further increasing the total life cycle cost of the equipment. Therefore, those skilled in the art have provided a circuit board with stable connection to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this invention is to provide a simple and reasonably designed circuit board with a stable connection in order to solve the above problems.

[0005] This utility model achieves the above-mentioned objectives through the following technical solution: it includes a connecting component and a housing, the housing door is hinged to the front side of the inner wall of the housing, the connecting component and the circuit board are jointly installed inside the housing, the connecting component includes a U-shaped mounting plate for mounting the circuit board, the circuit board is snapped into the U-shaped mounting plate, the front and rear sides of the U-shaped mounting plate are each equipped with a sub-lock component for stabilizing the U-shaped mounting plate, the front and rear sides of the housing are each equipped with a female lock component that cooperates with the sub-lock component, and the front and rear sides of the U-shaped mounting plate are each equipped with a tenon and mortise component for installing and removing the circuit board.

[0006] As a further optimization of this utility model, the sub-lock assembly includes mounting plates fixedly installed on both sides of the front and rear side walls of the U-shaped mounting plate. The four mounting plates are arranged in a rectangular array. Each of the four mounting plates has a connecting plate installed on its side wall. Each of the four connecting plates has a locking groove on its front side wall. The four locking grooves and the cavity between the corresponding mounting plate and the connecting plate together form a locking groove.

[0007] As a further optimization of this utility model, the main lock assembly includes an installation component installed on the side wall of the outer shell and the side wall of the door. The installation component includes four limiting plates that are respectively fixedly installed on both sides of the front and rear side walls of the outer shell and the door. The front and rear side walls of the four limiting plates are respectively connected to rotating cylinders that pass through and rotate. The other ends of the four rotating cylinders are respectively connected to the inside of the outer shell that pass through and rotate. An extension rod is fixedly installed on the other end of each of the four rotating cylinders. A lock head is fixedly installed on the other end of each of the four extension rods. The four lock heads are respectively matched and engaged with corresponding lock grooves and locking slots.

[0008] As a further optimization of this utility model, the two side walls of the outer shell are provided with mounting grooves located at the front and rear sides of the four limiting plates respectively. The inner side walls of the mounting grooves are fixedly installed with reset springs. The side walls of the four limiting plates are each equipped with a connecting rod. The connecting rods are slidably connected inside the corresponding mounting grooves and fixedly connected to one end of the corresponding reset springs.

[0009] As a further optimization of this utility model, the mortise and tenon assembly includes two first tenons that are respectively fixedly installed on the side wall of the U-shaped mounting plate. The two first tenons are symmetrically distributed. The two first tenons have a first mortise groove that is connected to each other on both side walls. The front side wall and the rear side wall of the first tenon have a second mortise groove that is connected to each other.

[0010] As a further optimization of this utility model, the side walls of the two first mortises are jointly engaged with a first mortise block, and the side walls of the two first mortises are jointly engaged with a second mortise block that penetrates the side wall of the first mortise block.

[0011] The beneficial effects of this utility model are as follows: 1. This utility model adopts the interlocking locking of the sub-lock assembly and the mother lock assembly, and achieves double stability with the mechanical nesting of the tenon and mortise assembly. The lock groove on the U-shaped mounting plate and the lock head of the outer shell are tightly engaged by the return spring, forming a strong constraint in the horizontal direction; the multi-layer nesting of the first mortise block, the second mortise block and the tenon groove in the tenon and mortise assembly further strengthens the vertical direction.

[0012] 2. This utility model achieves tool-free quick assembly and disassembly through the plug-in design of the tenon and mortise components and the rotation unlocking mechanism of the female lock component. During disassembly, it is only necessary to pull out the second mortise block and remove the first mortise block to separate the circuit board and the U-shaped mounting plate; pulling the limiting plate and rotating the rotating cylinder can release the lock between the U-shaped mounting plate and the outer shell.

[0013] 3. This utility model adopts a modular design, and the tenon and mortise components, the sub-lock components, and the main lock components can all be replaced independently. For example, when the tenon and mortise structure is worn due to long-term use, only the first mortise block and the second mortise block need to be replaced separately; if the mating surface between the lock head and the lock groove is damaged, the corresponding parts can also be quickly replaced.

It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0017] Example: Figure 1-5 As shown, the circuit board 1, connecting component 2, tenon and mortise component 3, outer shell 4, and main lock component are composed of the circuit board 1, connecting component 2, tenon and mortise component 3, outer shell 4 as the overall protective structure, with the shell door 8 hinged to the front side of its inner wall; connecting component 2 is used to install circuit board 1 and cooperates with main lock component on outer shell 4 through sub-lock component to achieve a stable connection; tenon and mortise component 3 facilitates the installation and removal of circuit board 1 in U-shaped mounting plate 201. Connecting component 2 includes U-shaped mounting plate 201, with circuit board 1 snapped into the inside of U-shaped mounting plate 201, providing installation space for circuit board 1. Sub-lock components are installed on both sides of the front and rear side walls of U-shaped mounting plate 201. Sub-lock components include mounting discs 203 fixedly installed on the side walls of U-shaped mounting plate 201. Four mounting discs 203 are arranged in a rectangular array. Each mounting disc 203 has a connecting disc 202 installed on its side wall. The front side wall of connecting disc 202 has a locking groove 204. The locking groove 204 and the cavity between the corresponding mounting disc 203 and connecting disc 202 together form a locking groove.

[0018] like Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 As shown, both sides of the front side wall and both sides of the rear side wall of the outer shell 4 are equipped with a female lock assembly that cooperates with the sub-lock assembly. The female lock assembly includes a mounting assembly 5 installed on the side wall of the outer shell 4 and the side wall of the shell door 8. The mounting assembly 5 includes four limiting plates 501 that are fixedly installed on both sides of the front side wall and the rear side wall of the outer shell 4 and the shell door 8, respectively. Each limiting plate 501 has a rotating cylinder 502 that passes through and rotatably connects to the front and rear side walls. The other end of the rotating cylinder 502 passes through and rotatably connects to the inside of the outer shell 4, and an extension rod 505 is fixedly installed at its end. A lock head 504 is fixedly installed at the other end of the extension rod 505. The lock head 504 matches and engages with the corresponding lock groove 204 and locking groove, respectively. Meanwhile, mounting grooves 6 are provided on both sides of the outer casing 4, respectively located at the front and rear sides of the four limiting discs 501. A return spring 7 is fixedly installed on the inner side wall of the mounting groove 6. A connecting rod 503 is installed on the side wall of each limiting disc 501. The connecting rod 503 is slidably connected inside the corresponding mounting groove 6 and fixedly connected to one end of the corresponding return spring 7. The return spring 7 can keep the lock head 504 stable after it is engaged.

[0019] As shown in the figure Figure 2 , Figure 3 , Figure 8 , Figure 10 As shown, tenon and mortise components 3 are installed on both sides of the front sidewall of the U-shaped mounting plate 201. The tenon and mortise components 3 include two first tenons 301 that are fixedly installed on the sidewall of the U-shaped mounting plate 201. The two first tenons 301 are symmetrically distributed. The two sidewalls of the first tenons 301 are provided with connected first mortises 302. The front sidewall and the rear sidewall are provided with connected second mortises 304. The sidewalls of the two first mortises 302 are engaged with a first mortise 305. The sidewalls of the two first mortises 302 are also engaged with a second mortise 303 that penetrates the sidewall of the first mortise 305. The circuit board 1 is fixed and disassembled through the tenon and mortise structure.

[0020] It should be noted that when using this utility model: when it is necessary to install the circuit board 1 into the U-shaped mounting plate 201, first place the circuit board 1 inside the U-shaped mounting plate 201 so that the edge of the circuit board 1 is aligned with the position of the first tenon 301. At this time, the edge part of the circuit board 1 is located between the two first tenons 301. Next, the first mortise 305 is inserted from the side into the first mortise 302 of the two first tenons 301. Since the first mortise 302 penetrates the two side walls of the first tenon 301 and the size of the first mortise 305 is closely matched with the first mortise 302, the first mortise 305 can be firmly embedded in the first mortise 302 and at the same time press down on the edge of the circuit board 1, restricting its movement in the horizontal direction. Finally, the second mortise 303 is inserted into the first tenon 302 from front to back or from back to front, and it passes through the side wall of the first mortise 305. The size of the second mortise 303 is also closely matched with the corresponding holes on the first tenon 302 and the first mortise 305, which further enhances the stability of the entire mortise and tenon structure. Through the insertion of the second mortise 303, the first mortise 305 is locked in the first tenon 302 and cannot be easily removed, thereby achieving the stable fixation of the circuit board 1 in the U-shaped mounting plate 201.

[0021] When installing the U-shaped mounting plate 201 containing the circuit board 1 into the housing 4, first open the housing door 8 of the housing 4 and place the U-shaped mounting plate 201 in the corresponding position. At this time, the locking groove 204 of the sub-lock assembly on the U-shaped mounting plate 201 is aligned with the locking groove and the lock head 504 of the female lock assembly on the housing 4. Next, push the limiting plate 501. Since the side wall of the limiting plate 501 is equipped with a connecting rod 503, and the connecting rod 503 is slidably connected in the mounting groove 6 and fixedly connected to one end of the return spring 7, when the limiting plate 501 is pulled, the connecting rod 503 will slide in the mounting groove 6, thereby pulling the return spring 7, so that the return spring 7 is in a stretched and stored state. Then, rotate the rotating drum 502. The rotating drum 502 drives the extension rod 505 and the lock head 504 to rotate, aligning the lock head 504 with the U-shaped mounting plate 201. When the lock head 504 is accurately aligned with the locking groove 204 on the U-shaped mounting plate 201, the limiting plate 501 is released. At this time, the return spring 7, which is in a compressed state, releases its elastic potential energy, thereby driving the limiting plate 501 and the lock head 504 to move forward, so that the lock head 504 is locked into the locking groove, realizing a stable connection between the U-shaped mounting plate 201 and the outer shell 4. Finally, the shell door 8 is closed to complete the installation operation.

[0022] When it is necessary to disassemble circuit board 1, first open the shell door 8 of the outer casing 4, then push the limiting plate 501 to make the connecting rod 503 slide in the mounting groove 6, and compress the return spring 7 again. At this time, the lock head 504 will move backward with the movement of the limiting plate 501 and gradually disengage from the locking groove on the U-shaped mounting plate 201. Then, rotate the rotating cylinder 502 to drive the lock head 504 to rotate, so that the lock head 504 is misaligned with the locking groove 204, further ensuring that the lock head 504 will not obstruct the removal of the U-shaped mounting plate 201. At this time, the U-shaped mounting plate 201 can be removed smoothly. After the circuit board 1 is removed from the U-shaped mounting plate 201, if it is necessary to reinstall the U-shaped mounting plate 201, follow the operation steps of the installation process and use the elastic potential energy of the return spring 7 to push the lock head 504 into the locking groove again to achieve a stable connection between the U-shaped mounting plate 201 and the outer casing 4.

[0023] When it is necessary to remove the circuit board 1 from the U-shaped mounting plate 201, first pull the second mortise 303 out of the first tenon 302 and the first mortise 305. Since the second mortise 303 is an independent component and its engagement with the first tenon 302 and the first mortise 305 is not a permanent connection, it can be removed by applying appropriate external force.

[0024] After the second mortise 303 is pulled out, the locking state of the first mortise 305 is released. At this time, the first mortise 305 can be removed from the first tenon 302. With the removal of the first mortise 305, the constraint of the circuit board 1 in the horizontal direction also disappears. At this time, the circuit board 1 can be easily removed from the U-shaped mounting plate 201, and the disassembly operation is completed.

[0025] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
