[0015] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0016] like Figures 1 to 4 As shown, the utility model provides a circuit board 100 for preventing circuits from loosening, which includes a first main body 10, a second main body 20 and a connecting shaft 30. The right end of the first main body 10 and the left end of the second main body 20 are both provided with connecting holes 40. The connecting shaft 30 is penetrated into the connecting holes 40 of the first main body 10 and the second main body 20 to connect the two, and the first main body 10 and the second main body 20 can both rotate along the connecting shaft 30.
[0017] The first main body 10 is also provided with a plurality of buckle terminals 11 and buckle grooves 12, and the buckle grooves 12 are respectively located outside the buckle terminals 11. The second main body 20 is correspondingly provided with a plurality of buckle blocks 21, and the buckle blocks 21 correspond to the buckle grooves 12 in upper and lower directions. The cross-sections of the buckle blocks 21 and the buckle grooves 12 are both designed in a conical structure.
[0018] After the connecting wire is connected to the buckle terminal 11, the second main body 20 can be rotated along the connecting axis 30 to be folded above the first main body 10. At this time, the buckle block 21 can snap the connecting wire into the buckle groove 12 for secondary fixation. Under the buckle fixation of the buckle terminal 11 and the buckle fixation of the buckle structure, the connection between the connecting wire and the circuit board will be more firm and reliable and not easy to loosen.
[0019] The second main body 20 is further provided with a plurality of adjustment slots 22 and adjustment screws 23. The plurality of buckle blocks 21 are respectively engaged in the adjustment slots 22. The adjustment screws 23 penetrate the second main body 20, and one end thereof extends into the adjustment slot 22 and is screwed to the buckle block 21. The adjustment screws 23 can adjust the distance between the buckle block 21 and the buckle slot 12, so that the buckle fixation of the two to the connecting wire is neither too loose and ineffective, nor too tight to affect the line transmission function.
[0020] The first main body 10 is also provided with a locking groove 13 and an elastic locking rod 14, wherein the elastic locking rod 14 is inserted into the first main body 10 and one end of the elastic locking rod 14 extends into the locking groove 13. The second main body 20 is also provided with a locking block 24, wherein the locking block 24 is correspondingly engaged in the locking groove 13 and is limited by the elastic locking rod 14. The locking structure can fix the folded first main body 10 and the second main body 20, thereby ensuring that the buckle structure can always play a role in buckling and fixing the connecting wire.
[0021] The bottom and both side edges of the buckle groove 12 are chamfered, and the bottom and both side edges of the buckle block 21 are chamfered. The rounded buckle structure is safer and more reliable, and can effectively avoid the problem of sharp edges cutting and puncturing the connecting wires and affecting the operation of the circuit board. The surfaces of the first main body 10 and the second main body 20 are also provided with a plurality of heat dissipation grooves 50. The structure of the heat dissipation grooves 50 not only increases the surface area of the circuit board, but also forms multiple heat dissipation channels, so that the heat generated by the circuit board during operation can be dissipated faster.
[0022] In summary, the beneficial effects of the circuit board 100 for preventing the line from loosening of the utility model are: by designing a circuit board with a folding and pressing structure to assist in pressing and fixing the connecting wires, the circuit board wiring is made more secure, which greatly improves the problem of accidental loosening of the connection between the terminal and the wire; the pressing block 21 is designed as an active adjustment structure, which can press and fix the connecting wires of different thicknesses, so that they can be firmly fixed and will not be deformed due to excessive pressure and affect the transmission performance; the rounded corner design can avoid accidents such as the connecting wires being punctured by sharp edges, and the locking structure on the main body can ensure that the circuit board is firmly folded and pressed to fix the wires, and the heat dissipation groove 50 can enhance the heat dissipation effect of the circuit board, and improve the problem of the folded circuit board affecting the heat dissipation capacity due to the increased thickness; the utility model is highly practical and has a strong promotional significance.
[0023] The above-mentioned embodiment only expresses one implementation method of the utility model, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
