A circuit board with anti-breakage function

Abstract

This utility model discloses a circuit board with anti-breakage function, belonging to the field of circuit board technology. The device includes a circuit board with multiple sets of buffer protrusions on its side edges to reduce stress concentration. The circuit board also has detachably mounted component protection mechanisms for protecting electrical components and solder joint protection mechanisms for protecting the solder joints at the bottom of the circuit board. In use, the upper plate protects various components on the circuit board, while the bottom plate absorbs external impact forces. When the impact force is too large, the bottom plate pushes the circuit board along the connecting posts, thereby absorbing the external impact through springs, reducing the impact of external forces on the circuit board and minimizing the possibility of breakage. When the side of the circuit board is impacted, the external impact force first acts on the buffer protrusions, which reduce stress concentration and absorb the stress generated by the impact in a timely manner, reducing damage to the circuit board body when dropped or impacted.

Description

Technical Field

[0001] This utility model relates to the field of circuit board technology, and in particular to a circuit board with anti-breakage function. Background Technology

[0002] A circuit board, also known as a printed circuit board (PCB), is an indispensable component of electronic equipment. It is manufactured using electronic printing technology, which forms conductive lines and holes on an insulating substrate according to a predetermined design, enabling electrical connections between electronic components.

[0003] On construction sites, equipment such as concrete mixers and welding machines are ubiquitous. These machines rely heavily on circuit boards for precise and efficient control. The circuit board acts as the "brain" of the equipment, accurately directing every operation and ensuring stable and reliable operation in complex construction environments, thus providing strong support for the smooth progress of construction projects.

[0004] The shortcomings of the existing technical solutions are as follows: On construction sites, equipment operation and handling are extremely frequent, with various machines and tools constantly running. The vibrations generated during this process, as well as collisions, drops, and improper handling, can easily cause circuit boards to vibrate or even be impacted, leading to breakage. Once a circuit board breaks, its components cannot be connected, and the equipment will malfunction. Due to the high integration and complex structure of circuit boards, once damaged, they are difficult to repair with ordinary mechanical equipment, which undoubtedly has a serious impact on project progress and quality. Utility Model Content

[0005] This invention provides a circuit board with anti-breakage function, which can solve the problem of circuit boards of equipment on construction sites being easily damaged and replaced due to collisions and drops in the use of existing technology.

[0006] A circuit board with anti-breakage function includes a circuit board with multiple sets of buffer protrusions on the side edge of the circuit board to reduce stress concentration. The circuit board is detachably mounted with an electrical component protection mechanism for protecting electrical components and a solder joint protection mechanism for protecting the solder joints at the bottom of the circuit board.

[0007] As a further embodiment of this utility model: a first connecting hole is provided at the corner of the circuit board, the electrical component protection mechanism includes an upper plate, a connecting post is fixedly provided at the corner of the upper plate, and a limiting component that can be detachably connected to the first connecting hole is provided on each set of the connecting posts.

[0008] As a further embodiment of this utility model: the limiting component includes a pressure sleeve plate that is slidably sleeved on the corresponding connecting column, a spring is provided between the pressure sleeve plate and the upper plate, and a storage groove is provided on the side of each connecting column away from the upper plate, and a positioning block is rotatably provided inside the storage groove on the side away from the upper plate.

[0009] As a further embodiment of this utility model: each set of the storage slots is provided on the same side of the corresponding connecting column.

[0010] As a further embodiment of this utility model: the weld point protection mechanism includes a base plate that is detachably connected to the connecting column.

[0011] As a further embodiment of this utility model: a second connecting hole is provided at the corner of the base plate to slide and engage with the corresponding connecting column.

[0012] As a further embodiment of this utility model, the size of the base plate is larger than the total size of the circuit board and the buffer protrusion.

[0013] As a further embodiment of this utility model: a limiting ring for separating the circuit board from the base plate is fixedly provided on the second connecting hole.

[0014] As a further embodiment of this utility model, the surface of the base plate is plated with a layer of copper.

[0015] As a further embodiment of this utility model: the upper plate is fixedly connected to a connecting plate that is connected to an external support.

[0016] The beneficial effects of this utility model are:

[0017] 1. When in use, this utility model protects various components on the circuit board through the upper plate and absorbs external impact through the bottom plate. When the impact is too large, the bottom plate will push the circuit board to move along the connecting column, and then absorb the external impact through the spring, reducing the impact of external impact on the circuit board and reducing the possibility of breakage.

[0018] 2. When this utility model is in use, when the circuit board is impacted from the side during handling, dropping, or use alone, the external impact force will first act on the buffer plate. The buffer plate can reduce stress concentration and absorb the stress generated by the impact in a timely manner, thereby reducing the damage to the circuit board body when it is dropped or impacted.

[0019] 3. When installing the upper and lower plates, the side of the upper plate with the connecting post can face upwards. The positioning block falls into the storage groove under gravity. Then, the circuit board and the lower plate are stacked, and the connecting post is passed through the first connecting hole on the circuit board and the corresponding second connecting hole on the lower plate in sequence. The circuit board and the lower plate are pressed down so that they are both located below the storage groove. Then, the lower plate, circuit board, and upper plate are flipped over, so that one end of the positioning block inside the storage groove falls out under gravity. The lower plate is then released, and it is pressed against the positioning block by the spring, thereby fixing the circuit board. The assembly method is relatively simple.

[0025] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0026] like Figures 1 to 3 As shown, this embodiment of the present invention provides a circuit board with anti-breakage function, including circuit board 1, as follows: Figure 1 As shown, the circuit board 1 is detachably equipped with an electrical component protection mechanism 2 for protecting electrical components and a solder joint protection mechanism 3 for protecting the solder joints at the bottom of the circuit board 1.

[0027] The circuit board 1 has a first connection hole 101 at its corner. The electrical component protection mechanism 2 includes an upper plate 201, which is fixedly connected to a connecting plate that is connected to an external support. A connecting post 202 is fixedly provided at the corner of the upper plate 201, and each set of connecting posts 202 is provided with a limiting component that is detachably connected to the first connection hole 101.

[0028] In one specific embodiment, the limiting component includes a pressure plate 203 that is slidably sleeved on the corresponding connecting post 202. A spring 204 is provided between the pressure plate 203 and the upper plate 201. Each set of connecting posts 202 has a storage groove 205 on the side away from the upper plate 201. A positioning block 206 is rotatably provided inside the storage groove 205 on the side away from the upper plate 201. Each set of storage grooves 205 is located on the same side of the corresponding connecting post 202. When assembling the circuit board 1 and the electrical component protection mechanism 2, the connecting post 202 can be passed through the first connecting hole 101 on the circuit board 1. Press the circuit board 1 and the base plate 301 so that both the circuit board 1 and the base plate 301 are located below the storage groove 205. Then flip the circuit board 1 and the upper plate 201 so that one end of the positioning block 206 inside the storage groove 205 falls out under the action of gravity. Release the circuit board 1, and the circuit board 1 is pressed against the positioning block 206 under the action of the spring 204, thereby fixing the circuit board 1.

[0029] It should be noted that the elasticity of the spring 204 needs to be sufficient to press and fix the circuit board 1 onto the positioning block 206, and it should not vibrate under external vibration. Those skilled in the art can select a spring 204 with sufficient elasticity as needed.

[0030] In this embodiment, the solder joint protection mechanism 3 includes a base plate 301 detachably connected to the connecting post 202. The base plate 301 has second connecting holes 302 at its corners that slide in conjunction with the corresponding connecting post 202. A limiting ring 303 is fixedly installed on the second connecting hole 302 to separate the circuit board 1 from the base plate 301, preventing the solder joints on the back of the circuit board 1 from directly contacting the base plate 301 and causing pins to detach. A layer of copper can be plated on the surface of the base plate 301 to improve heat dissipation efficiency, allowing heat between the circuit board 1 and the base plate 301 to be discharged through thermal conduction.

[0031] The sides of circuit board 1 typically lack internal copper layers or trace support, relying solely on the physical strength of the substrate (such as FR-4). Their resistance to bending / torsion is significantly lower than other areas, making them susceptible to stress, especially when circuit board 1 is fixed alone. In this embodiment, multiple sets of buffer protrusions 102 are provided along the side edges of circuit board 1 to reduce stress concentration. Figure 2 As shown, the buffer protrusion 102 is used to reduce stress concentration, thereby absorbing the stress generated by the impact in a timely manner and reducing damage to the circuit board 1 body from falling or impacting. The buffer protrusion 102 can be made of glass fiber epoxy resin or the same material as the circuit board 1 substrate.

[0032] In this embodiment, when the circuit board 1 is used in combination with the electrical component protection mechanism 2 and the solder joint protection mechanism 3, the size of the base plate 301 needs to be larger than the total size of the circuit board 1 and the buffer protrusion 102, so as to facilitate the protection of the circuit board 1 and the buffer protrusion 102.

[0033] Working principle: When the circuit board 1 is used in combination with the electrical component protection mechanism 2 and the solder joint protection mechanism 3, the side of the upper plate 201 with the connecting post 202 can be facing upwards. The positioning block 206 falls into the storage groove 205 under the action of gravity. Then, the circuit board 1 and the base plate 301 are stacked, and the connecting post 202 passes through the first connecting hole 101 on the circuit board 1 and the corresponding second connecting hole 302 on the base plate 301 in sequence. The circuit board 1 and the base plate 301 are pressed so that the circuit board 1 and the base plate 301 are both located below the storage groove 205. Then, the base plate 301, the circuit board 1 and the upper plate 201 are flipped over, so that one end of the positioning block 206 inside the storage groove 205 falls out under the action of gravity. The base plate 301 is released, and the base plate 301 is pressed against the positioning block 206 under the action of the spring 204, thereby fixing the circuit board 1. The upper plate 201 is used to protect various components on the circuit board 1, and the bottom plate 301 is used to absorb external impact. When the impact is too great, the bottom plate 301 will push the circuit board 1 to move along the connecting post 202, and then absorb the external impact through the spring 204, reducing the impact of external impact on the circuit board 1 and reducing the possibility of breakage.

[0034] When the circuit board 1 is impacted from the side during handling, dropping, or use alone, the external impact force will first act on the buffer plate 102. The buffer plate 102 can reduce stress concentration and absorb the stress generated by the impact in a timely manner, thereby reducing the damage to the circuit board 1 body when it is dropped or impacted.

[0035] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
