To this end, the utility model proposes a single-sided circuit board that can be spliced ​​and used, which solves the problem that after the circuit board is spliced, the current cannot pass smoothly due to loose splicing, and even short circuit, leakage and other safety problems may occur, thereby causing temperature rise and even fire.

[0007] To achieve the above-mentioned purpose, the utility model provides a single-sided circuit board that can be spliced ​​for use, comprising a single-sided circuit board, one side of the top of the single-sided circuit board is fixedly connected to a protective shell, the other side of the top of the single-sided circuit board is fixedly connected to a fixing plate, and a multifunctional fastening component is arranged inside the protective shell, wherein;

[0008] The multifunctional fastening assembly includes an airbag, both ends of which are fixedly connected with trigger rods, one end of the trigger rod is fixedly connected to the airbag, the other end of the trigger rod is rotatably connected to a rotating rod, one end of the rotating rod is rotatably connected to the trigger rod, the other end of the trigger rod is rotatably connected to a second clamping ring, the second clamping ring is slidably connected to the inside of a protective shell, the inside of the rotating rod is rotatably connected to a rotating shaft rod, the bottom of the rotating shaft rod is fixedly connected to the protective shell, the top of the rotating shaft rod is threadedly connected with a nut, the side wall of the rotating rod is fixedly connected to a push rod, the inside of the protective shell is fixedly connected with a first clamping ring, the first clamping ring and the second clamping ring have the same shape, and the first clamping ring and the second clamping ring are arranged opposite to each other.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. Through the setting of the multifunctional fastening assembly, when the temperature of the connection position of a pair of circuit boards continues to rise, the airbag will expand due to the factors of thermal expansion and contraction, and the airbag will expand to both sides in the protective shell. At this time, the trigger rod moves to both sides under the drive of the airbag. At this time, the rotating rod rotates under the drive of the trigger rod, and the rotating rod drives the second clamping ring to slide. The second clamping ring slides in the direction close to the spring baffle. At this time, the plug-in block loses the clamping effect of the first clamping ring and the second clamping ring.

When the single-sided circuit board is overheated and a fire occurs due to certain factors, a pair of single-sided circuit boards can be separated immediately to prevent the spread of the fire, thereby effectively reducing losses. In addition, when the fire has not yet started but the temperature continues to rise, timely separation can achieve the effect of power off, thereby avoiding the formation of fire at the root.

[0017] 2. Through the setting of the emergency component, when the multifunctional fastening component starts to work, the rotating rod will rotate, and the rotating rod will drive the small rod to rotate. As the small rod moves, the end of the small rod will be stuck in the L-shaped plate, thereby driving the rotating door panel to rotate. A gap will appear between the rotating door panel and the pipeline. At this time, the liquid in the airbag will be directly sprayed out through the pipeline, thereby achieving the effect of auxiliary cooling and auxiliary fire extinguishing.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1-4As shown, a single-sided circuit board that can be spliced ​​for use includes a single-sided circuit board 1, a protective shell 2 is fixedly connected to one side of the top of the single-sided circuit board 1, and a fixing plate 21 is fixedly connected to the other side of the top of the single-sided circuit board 1.

[0025] The side wall of the fixing plate 21 is fixedly connected with an inserting block 22 , and the side wall of the inserting block 22 is fixedly connected with a clamping plate 23 .

[0026] A multifunctional fastening assembly 3 is disposed inside the protective shell 2 . The multifunctional fastening assembly 3 includes an air bag 31 . Both ends of the air bag 31 are fixedly connected to a trigger rod 32 . A pipe 321 is provided inside the trigger rod 32 .

[0027] One end of the trigger rod 32 is fixedly connected to the airbag 31. When the temperature of the connection position of a pair of circuit boards continues to rise, the airbag 31 will expand due to the factors of thermal expansion and contraction. The airbag 31 expands to both sides in the protective shell 2. The other end of the trigger rod 32 is rotatably connected to the rotating rod 33. One end of the rotating rod 33 is rotatably connected to the trigger rod 32. The trigger rod 32 will move to both sides under the action of the force brought by the expansion of the airbag 31. The trigger rod 32 will drive the rotating rod 33 to rotate with the rotating shaft 34 as the center of the circle. The other end of the trigger rod 32 is rotatably connected to the second snap ring 361. The second snap ring 361 is slidably connected to the inside of the protective shell 2. The inside of the rotating rod 33 is rotatably connected to the rotating shaft 34. The rotating shaft The bottom of 34 is fixedly connected to the protective shell 2, the top of the rotating shaft 34 is threadedly connected with a nut 35, the side wall of the rotating rod 33 is fixedly connected with a push rod 341, the inside of the protective shell 2 is fixedly connected with a first snap ring 36, the plug block 22 is clamped in the area surrounded by the first snap ring 36 and the second snap ring 361, the rotating rod 33 drives the second snap ring 361 to slide, and the second snap ring 361 slides toward the direction close to the spring baffle 4, at this time the plug block 22 loses the clamping effect of the first snap ring 36 and the second snap ring 361, as the rotating rod 33 rotates, the push rod 341 will contact with one end of the plug block 22 extending into the protective shell 2, and the plug block 22 will be squeezed out of the protective shell 2 by the push rod 341, thereby achieving the effect of expelling.

[0028] The advantage of this design is that this operation can be completed without human influence. When the temperature of the single-sided circuit board 1 is too high and a fire occurs due to certain factors, a pair of single-sided circuit boards 1 can be separated immediately to prevent the spread of the fire, thereby effectively reducing losses. In addition, when the fire has not started but the temperature continues to rise, timely separation can achieve the effect of power off, thereby avoiding the formation of fire at the root.

[0029] One end of the insert block 22 with a clamping plate 23 can be clamped between the first clamping ring 36 and the second clamping ring 361 to achieve a splicing effect. The first clamping ring 36 and the second clamping ring 361 have the same shape and are arranged opposite to each other.

[0030] A spring baffle 4 is fixedly connected to the inside of the protective shell 2, and an elastic spring 41 is fixedly connected to one side of the spring baffle 4 close to the second retaining ring 361. The two ends of the elastic spring 41 are respectively fixedly connected to the spring baffle 4 and the second retaining ring 361. The second retaining ring 361 is tightly pushed by the elastic spring 41, thereby achieving the effect of firmly fixing the plug 22.

[0031] The protective shell 2 is provided with an emergency component 5 inside, and the emergency component 5 includes a rotating door plate 51, which is rotatably connected to one end of the trigger rod 32 close to the rotating rod 33. The rotating door plate 51 is arranged inside the pipe 321, and one end of the rotating door plate 51 is rotatably connected to the trigger rod 32, and the other end of the rotating door plate 51 is fixedly connected to an L-shaped plate 52, and the rotating rod 33 is fixedly connected to a side of the rotating door plate 51 close to the rotating door plate 51. When the multifunctional fastening component 3 starts to work, the rotating rod 33 will rotate, and the rotating rod 33 drives the small rod 53 to rotate. As the small rod 53 moves, the end of the small rod 53 will be stuck in the L-shaped plate 52, thereby driving the rotating door plate 51 to rotate, and a gap will appear between the rotating door plate 51 and the pipe 321. At this time, the liquid in the airbag 31 will be directly sprayed out through the pipe 321, so as to achieve the effect of auxiliary cooling and auxiliary fire extinguishing. The L-shaped plate 52 is L-shaped, and the small rod 53 is stuck in the L-shaped plate 52.

[0032] Working principle: first place the circuit board to be spliced ​​at the specified position, then clamp one end of the plug-in block 22 with the clamping plate 23 between the first clamping ring 36 and the second clamping ring 361, and the second clamping ring 361 is tightly pushed by the elastic spring 41 to achieve the effect of firmly fixing the plug-in block 22.

[0033] When the temperature at the connection position of a pair of circuit boards continues to rise, the airbag 31 will expand due to thermal expansion and contraction, and the airbag 31 will expand to both sides in the protective shell 2. At this time, the trigger rod 32 moves to both sides under the drive of the airbag 31. At this time, the rotating rod 33 rotates under the drive of the trigger rod 32, and the rotating rod 33 drives the second snap ring 361 to slide. The second snap ring 361 slides in the direction close to the spring baffle 4. At this time, the plug block 22 loses the effect of the first snap ring 36 and the second snap ring 361 being engaged. As the rotating rod 33 rotates, the push rod 341 will contact the end of the plug block 22 extending into the protective shell 2, and the plug block 22 will be squeezed out of the protective shell 2 by the push rod 341, thereby achieving the effect of driving away.

[0034] When the multifunctional fastening assembly 3 starts to work, the rotating rod 33 will rotate, and the rotating rod 33 drives the small rod 53 to rotate. As the small rod 53 moves, the end of the small rod 53 will be stuck in the L-shaped plate 52, thereby driving the rotating door plate 51 to rotate. A gap will appear between the rotating door plate 51 and the pipe 321. At this time, the liquid in the airbag 31 will be directly sprayed out through the pipe 321, thereby achieving the effect of auxiliary cooling and auxiliary fire extinguishing.

[0035] The above embodiments are only used to illustrate the technical method of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical method of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the utility model.
