Abstract
Description
Technical Field
[0001] This utility model relates to a spliced double-layer printed circuit board. Background Technology
[0002] A double-sided printed circuit board (PCB) is a PCB with conductive patterns (usually copper foil) arranged on both sides of the substrate. This means that not only can electronic components and traces be arranged on one side of the PCB, but additional components and circuit paths can also be arranged on the other side. This design provides more wiring space and flexibility than a single-sided board, making it suitable for more complex circuit designs.
[0003] For applications requiring a large number of signal transmissions, routing directly between adjacent circuit boards can simplify the wiring complexity of the entire system, reduce the error rate, and help improve signal integrity. At the same time, making different functional modules into independent circuit boards and then splicing them together can make the system design more modular. However, since the spliced circuit boards still need to be separated when they are not spliced, most existing spliced circuit boards are connected by snap-fitting, bolting, or other methods.
[0004] However, for snap-fit splicing circuit boards, when a single circuit board needs to be replaced or repaired, it must be carefully separated from the other circuit boards. This increases the operation time and complexity. Moreover, since the plugs and slots are directly machined onto the circuit board, once damaged, it usually means that the entire circuit board needs to be replaced. Furthermore, directly setting the plugs and slots on the circuit board may limit the design freedom of the circuit layout, because space must be reserved for these mechanical interfaces. Therefore, how to preserve the design freedom of the circuit layout of each circuit board while reducing the damage to the circuit board caused by the force separation of the plugs and slots when replacing or repairing a single circuit board has become an urgent problem to be solved by those skilled in the art. Summary of the Invention
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a splicing double-layer printed circuit board that places the circuit boards to be spliced into a reinforcing frame, thereby reducing the possibility of damage to the circuit boards during the assembly and disassembly of the circuit boards and the reinforcing frame.
[0006] To achieve the above objectives, this utility model provides the following technical solution: It includes a first plate and a second plate, both extending horizontally along their length, with the first plate located to the right of the second plate. It also includes a reinforcing frame, on which a mounting groove is provided for the first and second plates to be inserted. A first outer plate is installed on the outer periphery of the first plate, and a second outer plate is installed on the outer periphery of the second plate. The first and second outer plates abut against each other on one side. Both the first and second outer plates are made of a material prone to deformation. Mounting components are installed on both sides of the mounting groove on the reinforcing frame. Mounting slots are provided on both the first and second outer plates for the mounting components to be inserted. Each mounting component is fastened and connected to the first and second outer plates.
[0007] The present invention is further configured such that: a first mating plate is provided at the bottom of the mounting slot of the first outer plate, and the first mating plate is inserted into the mounting slot and located at the bottom of the mounting component.
[0008] The present invention is further configured such that: the mounting component includes a top guide section and a fixing section located below the guide section; the first mating plate is inserted into a mounting groove and located at the bottom of the fixing section; the guide section is configured in a trapezoidal shape that is narrower at the top and wider at the bottom; the guide section includes a guide surface, and the guide surface is inclined from top to bottom and from left to right.
[0009] The present invention is further configured such that: the first outer plate protrudes to the left and is provided with a plurality of left mating blocks, and the second outer plate is provided with left mating slots corresponding to each left mating block.
[0010] The present invention is further configured such that: the second outer plate protrudes to the right and is provided with a plurality of right mating blocks, and the first outer plate is provided with a right mating slot corresponding to each right mating block.
[0011] The present invention is further configured such that: the reinforcing frame is provided with a plurality of reinforcing members between adjacent mounting members, each reinforcing member includes an mounting section, an insertion section and a limiting section, each mounting section is fixed to the reinforcing frame, each insertion section is inserted into the first outer plate and each limiting section abuts against the bottom of the first outer plate, the first outer plate is provided with a slot for the corresponding insertion section to be inserted, the width of the slot is greater than that of the insertion section and less than that of the limiting section.
[0012] The present invention is further configured such that each of the reinforcing members is provided with a deformation groove between the corresponding insertion section and the limiting section.
[0013] By adopting the above technical solution, 1. Since the first outer plate and the second outer plate are respectively installed circumferentially on the first plate body and the second plate body, the freedom of circuit layout design of the first plate body and the second plate body will not be affected. Furthermore, if it is necessary to process plugs and slots, they will be located on the first plate body and the second plate body, thus not affecting the circuit layout on the circuit board; 2. Since the first plate body and the second plate body are respectively connected to the mounting parts on both sides of the reinforcing frame in the mounting slot, the first plate body and the second plate body can be stably located in the reinforcing frame to achieve splicing of the two. When it is necessary to separate the two, by applying force to each mounting part, the first plate body and the second plate body will deform and separate from the reinforcing frame, thereby realizing the removal of the first plate body and the second plate body from the mounting slot, thus realizing the separation of the spliced first plate body and the second plate body; 3. The plate body made of a material that is prone to deformation can be more easily embedded into the mounting slot during installation, and the reinforcing frame provides the necessary support to prevent deformation.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] like Figures 1-7As shown, this utility model discloses a spliced double-layer printed circuit board, including a first board body 1 and a second board body 2 (the first board body 1 and the second board body 2 are conventional structures of circuit boards and are known to those skilled in the art, and will not be described in detail here). The length direction of the first board body 1 and the second board body 2 both extend left and right, with the first board body 1 located to the right of the second board body 2. It also includes a reinforcing frame 3, on which mounting grooves 31 are provided for the first board body 1 and the second board body 2 to be inserted. The outer periphery of the first board body 1 is equipped with... A first outer plate 11 is attached to the outer periphery of the second plate 2, and a second outer plate 21 is installed on the outer periphery of the second plate 2. The first outer plate 11 and the second outer plate 21 abut against each other on one side. Both the first outer plate 11 and the second outer plate 21 are made of rubber or other easily deformable materials. The reinforcing frame 3 has mounting parts 32 installed on both the left and right sides of the mounting groove 31. The first outer plate 11 and the second outer plate 21 are each provided with mounting slots 112 for the mounting parts 32 to be inserted. Each mounting part 32 is fastened to the first outer plate 11 and the second outer plate 21. 1. Due to the first... The outer plate 11 and the second outer plate 21 are respectively mounted circumferentially on the first plate 1 and the second plate 2, thus not affecting the freedom of circuit layout design of the first plate 1 and the second plate 2. Furthermore, if it is necessary to process plugs or slots, they will be located on the first plate 1 and the second plate 2, thus not affecting the circuit layout on the circuit board; 2. Since the first plate 1 and the second plate 2 are respectively connected to the mounting parts 32 located on both sides of the mounting groove 31 of the reinforcing frame 3, it is possible to ensure that the first plate 1 and the second plate 2 can be stably positioned on the reinforcing frame. The two plates are joined together within the frame 3. When they need to be separated, force is applied to each mounting component 32, causing the first plate 1 and the second plate 2 to deform and separate from the reinforcing frame 3. This allows the first plate 1 and the second plate 2 to be removed from the mounting slot 31, thus enabling the separation of the joined first plate 1 and the second plate 2. 3. Plates made of easily deformable materials can be more easily embedded into the mounting slot 31 during installation, and the reinforcing frame 3 provides the necessary support to prevent deformation.
[0028] The first outer plate 11 is provided with a first mating plate 111 at the bottom of the mounting slot 112. The first mating plate 111 is inserted into the mounting slot 112 and is located at the bottom of the mounting member 32. When the first outer plate 11 is installed into the reinforcing frame 3, the first mating plate 111 will enter the bottom of the mounting member 32 after the mounting member 32 is installed into the mounting slot 112 on the first outer plate 11. The first mating plate 111 can support the mounting member 32. If the first outer plate 11 shakes relative to the reinforcing frame 3, the first mating plate 111 will face upward and abut against the mounting member 32, making it difficult to pass over. Thus, the first mating plate 111 can be stably located below the mounting member 32, and the first outer plate 11 can be stably located within the reinforcing frame 3.
[0029] Preferably, the mounting component 32 includes a top guide section 321 and a fixing section 322 located below the guide section 321. The first mating plate 111 is inserted into the mounting slot 31 and is located at the bottom of the fixing section 322. The guide section 321 is a trapezoidal shape with a narrow top and a wide bottom. The guide section 321 includes a guide surface 3211, which is inclined from top to bottom and from left to right. Since the guide surface 3211 is inclined from top to bottom and from left to right, the contact area between the mounting component 32 and the first mating plate 111 in the horizontal direction can be increased, thus enabling the two to be connected more stably. Furthermore, since the guide section 321 is trapezoidal and the fixing section 322 is located below the guide section 321, the bottom of the guide section 321 is the widest point, making it difficult for it to move downward relative to the mounting slot 112. This allows the mounting component 32 to be stably located in the mounting slot 112 of the first mating plate 111, thus achieving a stable fit with the first mating plate 111.
[0030] The first outer plate 11 has several left mating blocks 113 protruding to the left, and the second outer plate 21 has left mating slots 211 corresponding to each left mating block 113. Since the left mating blocks 113 on the first outer plate 11 can be inserted into the left mating slots 211 of the second outer plate 21, the relative positions of the first outer plate 11 and the second outer plate 21 can be determined. This allows the other side of the first outer plate 11 to be connected to the other side of the second outer plate 21 while the mounting parts 32 are connected to the first outer plate 11 and the second outer plate 21, thus ensuring the lateral stability of the two outer plates, reducing the possibility of relative displacement, and improving the reliability of the overall structure.
[0031] Preferably, the second outer plate 21 is provided with a plurality of right mating blocks 212 protruding to the right, and the first outer plate 11 is provided with a right mating slot 114 corresponding to each right mating block 212, which further enhances the connection strength between the first outer plate 11 and the second outer plate 21, and provides additional support from another direction (away from the reinforcing frame 3 side) to ensure that the two outer plates fit tightly and avoid loosening or misalignment.
[0032] Furthermore, the reinforcing frame 3 is provided with several reinforcing members 4 made of easily deformable materials such as rubber between adjacent mounting members 32. Each reinforcing member 4 includes an mounting section 41, an insertion section 42, and a limiting section 43. Each mounting section 41 is fixed to the reinforcing frame 3. Each insertion section 42 is inserted into the first outer plate 11, and each limiting section 43 abuts against the bottom of the first outer plate 11. The first outer plate 11 is provided with reinforcing slots 115 for the corresponding insertion sections 42 to be inserted. The width of the reinforcing slots 115 is greater than that of the insertion section 42 and less than that of the limiting section 43. By providing reinforcing members 4, additional support can be provided for the connection between the first outer plate 11 and the reinforcing frame 3, enhancing its structural strength and preventing deformation caused by external pressure. 2. The first outer plate 11 needs to be inserted to achieve the abutment between the limiting section 43 and the first outer plate 11. Therefore, the first outer plate 11 needs to be pried from the bottom of the reinforcing frame 3 (i.e. the side where the limiting section 43 is located) to force the limiting section 43 to pass through the reinforcing slot 115 and achieve the abutment between the limiting section 43 and the first outer plate 11, thereby further improving the connection strength between the reinforcing member 4 and the first outer plate 11. When it is necessary to separate the reinforcing member 4 and the first outer plate 11, the limiting section 43 is pried downward to allow the first outer plate 11 to pass through the limiting section 43 downward. At the same time, an outward (i.e., away from the mounting slot 31 side) force is applied to the reinforcing frame 3 so that the mounting member 32 can be separated from the first outer plate 11 and the second outer plate 21, thereby realizing the removal of the single circuit board.
[0033] Preferably, each of the reinforcing members 4 is provided with a deformation groove 44 between the corresponding insertion section 42 and the limiting section 43. The presence of the deformation groove 44 makes it easier for the reinforcing member 4 to be bent and deformed when subjected to external force, thereby better adapting to different installation environments and conditions, while also protecting the reinforcing member 4 itself from damage and extending its service life.
[0034] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
