Description

Technical Field

[0001] The utility model relates to the technical field of protection, in particular to an anti-bending circuit mainboard. Background Art

[0002] Circuit boards, also known as electronic circuit boards, are mainly used to install and fix various electronic components and ensure that the components can stably exchange information. Circuit boards are mostly installed in chassis. Due to external environmental factors, such as earthquakes, external force impacts, etc., since the circuit boards are directly fixed inside the chassis, when the chassis breaks, the deformed and broken chassis will squeeze and deform together with the circuit boards fixed inside it. The deformation of the circuit boards will cause data loss or damage inside the electronic components. Utility Model Content

[0003] In view of the shortcomings of the prior art, the technical solution adopted by the utility model to solve the technical problems is: an anti-bending circuit mainboard, comprising:

[0004] A circuit board, which is an electronic circuit board used for wiring and installation of electronic components; a plug, which is connected to external equipment for data exchange and is made of metal, and the outer wall of the plug is fixedly connected to the outer wall of the circuit board; a protective component, which is used to protect against external impact, and the bottom of the protective component is fixedly connected to the outer wall of the circuit board.

[0005] Preferably, the four corners of the circuit board are provided with connection holes, and the pins are arranged linearly along the outer wall of the circuit board. The entire device is placed inside the external device, the pins are inserted into the external device, and the two connecting rods are fixedly connected to the inside of the external device. Since the number and area of ​​the pins are larger than the connecting plate, when the external force is too large and the outer shell of the external device is bent, since the bottom end of the connecting rod is fixed in the outer shell, the bending resistance of the connection between the connecting plate and the connecting frame is smaller than the bending resistance of the pins, and the connection between the connecting plate and the connecting frame will break first after reaching the bending limit. At this time, the circuit board is only plugged into the inside of the external device through the pins. Compared with the traditional direct fixation, the utility model can transfer the external bending force to the connecting frame, so that the connecting frame can bear the external force first, which can effectively prevent the bending and breaking of the circuit board.

[0006] Preferably, the protection assembly includes an arc rod and a connecting frame, the arc rod and the connecting frame are symmetrically arranged and mounted on the top of the circuit board. The two ends of the arc rod away from the pins are fixedly connected to a connecting plate, the inner wall of the connecting plate is fixedly connected to a connecting rod, and the bottom end of the connecting rod is fixedly connected to the device housing.

[0007] Preferably, the outer walls on both sides of the connecting frame are fixedly connected to the outer wall of the connecting plate, the top of the connecting frame is fixedly connected with a silicone pad, the bottom of the connecting frame is slidably connected with a buffer plate, the bottom of the buffer plate is slidably connected with a heat conducting plate, and the outer walls on both sides of the heat conducting plate are fixedly connected with heat dissipation silicone grease strips. Heat dissipation holes are provided in the wall of the heat conducting plate, and the outer wall of the heat conducting plate is fixedly connected with a buckle, and the buckle is clamped on the outside of the four corners of the circuit board. The silicone pad is linearly arranged along the outer wall at the top of the connecting frame, the buffer plate is linearly arranged along the outer wall at the bottom of the connecting frame, the outer walls on both sides of the heat conducting plate are fixedly connected to the outer wall of the connecting frame, the bottom of the heat conducting plate is fixedly connected to the top of the circuit board, and the buckle is symmetrically arranged on one side of the heat conducting plate.

[0008] The circuit board is fixed to the heat conducting plate through connecting holes and buckles. When the equipment is in use, the electronic components on the outer wall of the circuit board work, and the heat conducting plate assists in heat dissipation through the heat dissipation silicone grease strips and heat dissipation holes. Part of the heat is conducted to the buffer plate on the top of the heat conducting plate. Since the buffer plate is "W" shaped and thin, the buffer plate is deformed by heat and stretches slightly along the space at the bottom of the connecting frame. When external force impacts the external device and causes damage to the chassis of the external device, the pressure is further transmitted to the circuit board. At this time, the silicone pad performs preliminary buffering, the connecting frame squeezes the buffer plate, the buffer plate absorbs the impact, straightens and accumulates force, and converts the external impact force into elastic potential energy of the buffer plate. By utilizing energy conversion, the impact strength of the external force on the circuit board is reduced, thereby protecting the circuit board, that is, the circuit board. When the circuit board is forced to bend, the two ends of the arc rod are squeezed and contracted toward the middle, and the arc rod is further bent. Moreover, since the arc rod is in the shape of a bow, it can assist the mechanism in resetting while resisting a certain intensity of pressure to prevent the circuit board from being excessively bent.

[0009] The beneficial effects of the utility model are as follows:

[0010] 1. The utility model is provided with pins and connecting rods. When the device is in use, the entire device is placed inside the external device, the pins are inserted into the external device, and the two connecting rods are fixedly connected to the inside of the external device. Since the number and area of ​​the pins are larger than those of the connecting plate, when the external force is too large and the shell of the external device is bent, since the bottom end of the connecting rod is fixed in the shell, the bending resistance of the connection between the connecting plate and the connecting frame is smaller than the bending resistance of the pins, the connection between the connecting plate and the connecting frame will break first after reaching the bending limit. At this time, the circuit board is only plugged into the inside of the external device through the pins. Compared with the traditional direct fixation, the utility model can transfer the external bending force to the connecting frame, so that the connecting frame can bear the external force first, which can effectively prevent the bending and breakage of the circuit board.

[0011] 2. The utility model sets a protective component, and the circuit board is fixed to the heat conducting plate through connecting holes and buckles. When the equipment is in use, the electronic components on the outer wall of the circuit board work, and the heat conducting plate assists in heat dissipation through the heat dissipation silicone grease strips and heat dissipation holes. Part of the heat is conducted to the buffer plate on the top of the heat conducting plate. Since the buffer plate adopts a "W" shape and is relatively thin, the buffer plate is deformed by heat and stretches slightly along the space at the bottom of the connecting frame. When external force impacts the external device, causing damage to the chassis of the external device, the pressure is further conducted to the circuit board. At this time, the silicone pad performs preliminary buffering, the connecting frame squeezes the buffer plate, the buffer plate absorbs the impact, straightens and accumulates force, and converts the external impact force into the elastic potential energy of the buffer plate. By utilizing energy conversion, the impact strength of the external force on the circuit board is reduced, thereby protecting the circuit board, that is, the circuit board. When the circuit board is bent with force, the two ends of the arc rod are squeezed and contracted toward the middle, and the arc rod is further bent. Moreover, since the arc rod adopts a bow shape, it can assist the mechanism in resetting while resisting a certain intensity of pressure to prevent the circuit board from being excessively bent.

[0018] Embodiment 1:

[0019] See also Figure 1 - Figure 4 The utility model provides a technical solution: a bending-resistant circuit mainboard, comprising: a circuit board 1, which is an electronic circuit board for wiring and installing electronic components; a pin 2, which is connected to an external device for data exchange and is made of metal. The outer wall of the pin 2 is fixedly connected to the outer wall of the circuit board 1; a protective component 3, which is used to protect against external impact, and the bottom of the protective component 3 is fixedly connected to the outer wall of the circuit board 1.

[0020] The four corners of the circuit board 1 are provided with connection holes 4, and the pins 2 are arranged linearly along the outer wall of the circuit board 1. The protection component 3 includes an arc rod 5 and a connecting frame 6, which are symmetrically arranged and mounted on the top of the circuit board 1.

[0021] The two ends of the arc rod 5 close to the pin 2 are fixedly connected to the outer wall of the connecting frame 6, and the two ends of the arc rod 5 away from the pin 2 are fixedly connected to the connecting plate 7, and the inner wall of the connecting plate 7 is fixedly connected to the connecting rod 8, and the bottom end of the connecting rod 8 is fixedly connected to the device housing. The outer walls of the connecting frame 6 on both sides are fixedly connected to the outer wall of the connecting plate 7, and the top of the connecting frame 6 is fixedly connected to the silicone pad 9, and the bottom of the connecting frame 6 is slidably connected to the buffer plate 10, and the bottom of the buffer plate 10 is slidably connected to the heat conducting plate 11, and the outer walls on both sides of the heat conducting plate 11 are fixedly connected to the heat dissipation silicone grease strips 12.

[0022] Heat dissipation holes 13 are provided in the wall of the heat conducting plate 11, and buckles 14 are fixedly connected to the outer wall of the heat conducting plate 11, and the buckles 14 are clamped on the outside of the four corners of the circuit board 1. The silicone pads 9 are linearly arranged along the outer wall at the top of the connecting frame 6, and the buffer plate 10 is linearly arranged along the outer wall at the bottom of the connecting frame 6. The outer walls on both sides of the heat conducting plate 11 are fixedly connected to the outer wall of the connecting frame 6, and the bottom of the heat conducting plate 11 is fixedly connected to the top of the circuit board 1, and the buckles 14 are symmetrically arranged on one side of the heat conducting plate 11.

[0023] Working principle:

[0024] When the device is in use, the entire device is placed inside the external device, the pin 2 is inserted into the external device, and the two connecting rods 8 are fixedly connected to the inside of the external device. Since the number and area of ​​the pins 2 are larger than the connecting plate 7, when the external force is too large and the outer shell of the external device is bent, since the bottom end of the connecting rod 8 is fixed in the outer shell, the bending resistance of the connection between the connecting plate 7 and the connecting frame 6 is less than the bending resistance of the pin 2. The connection between the connecting plate 7 and the connecting frame 6 will break first after reaching the bending limit. At this time, the circuit board 1 is only plugged into the inside of the external device through the pin 2. Compared with the traditional direct fixation, the utility model can transfer the external bending force to the connecting frame 6, so that the connecting frame 6 can bear the external force first, which can effectively prevent the bending and breakage of the circuit board.

[0025] The circuit board 1 is fixed to the heat conducting plate 11 through the connecting hole 4 and the buckle 14. When the device is in use, the electronic components on the outer wall of the circuit board 1 work, and the heat conducting plate 11 assists in heat dissipation through the heat dissipation silicone grease strip 12 and the heat dissipation hole 13. Part of the heat is transferred to the buffer plate 10 on the top of the heat conducting plate 11. Since the buffer plate 10 is "W" shaped and thin, the buffer plate 10 is deformed by heat and stretches slightly along the space at the bottom of the connecting frame 6. When external force impacts the external device, causing the external device chassis to be damaged, the pressure is further transferred to the circuit board. At this time, the silicone pad 9 During the preliminary buffering, the connecting frame 6 squeezes the buffer plate 10, and the buffer plate 10 absorbs the impact, straightens and stores force, and converts the external impact force into the elastic potential energy of the buffer plate 10. By utilizing the energy conversion, the impact strength of the external force on the circuit board 1 is reduced, thereby protecting the circuit main board, that is, the circuit board 1. When the circuit board 1 is bent with force, the two ends of the arc rod 5 are squeezed and contracted toward the middle, and the arc rod 5 is further bent. Moreover, since the arc rod 5 adopts a bow shape, it can resist a certain intensity of pressure while resetting the auxiliary mechanism to prevent the circuit board 1 from being excessively bent.
