Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: an anti-folding reinforced PCB comprises a PCB main body 5, wherein an edge strip 1 is arranged on the back of the PCB main body 5, the edge strip 1 and the PCB main body 5 are connected through screws 4, the connection mode is convenient to disassemble and assemble, the edge strip 1 is distributed around the PCB main body 5, the structure enables the edge strip 1 to uniformly reinforce the periphery of the PCB main body 5, the firmness of the edge of the PCB main body 5 is improved, a first batten 3 and a second batten 8 are connected between the edge strips 1, two ends of the first batten 3 and two ends of the second batten 8 are respectively connected with the edge strips 1 on the front side, the rear side, the left side and the right side of the PCB main body 5, the first batten 3 and the second batten 8 and the edge strip 1 are integrally formed during production, such as injection molding and the like, the structure improves the integrity among the three modes, the device is more stable, the first batten 3 and the second batten 8 are distributed in a criss-cross mode, the distribution mode can enable the PCB main body 5 to be stressed more uniformly, the first lath 3 and the second lath 8 are perpendicular to the PCB main body 5, the arrangement enables the first lath 3 and the second lath 8 to have stronger bending resistance, one sides of the first lath 3 and the second lath 8 corresponding to the PCB main body 5 are respectively provided with a supporting head 7, the supporting head 7 and the first lath 3 and the second lath 8 are integrally formed, the end part of the supporting head 7 is propped against the back surface of the PCB main body 5, the supporting head 7 can support the PCB main body 5 by taking the first lath 3 and the second lath 8 as supporting points, the PCB main body 5 is divided into a plurality of small stress areas from a whole large stress area, thereby the strength of the PCB main body 5 can be greatly improved, the bending and breaking conditions are effectively prevented, the supporting heads 7 are uniformly distributed on the first lath 3 and the second lath 8, and the distribution mode enables the stress of the PCB main body 5 to be more uniform, the bending resistance is further improved, the two ends of the first lath 3 and the second lath 8 are respectively connected with one side of the end support 2, the other side of the end support 2 is connected with the edge strip 1, the end support 2 is triangular, the end support 2 is welded with the first lath 3, the second lath 8 and the edge strip 1, the triangular structure is very stable, the stability of the joint of the first lath 3, the second lath 8 and the edge strip 1 can be improved, through holes 6 matched with the structure are respectively arranged at the intersection of the first lath 3 and the second lath 8 and the PCB main body 5, the structure enables the PCB main body 5 and the equipment to be connected through the through holes, and the through holes are the junction of the first lath 3 and the second lath 8, make PCB board main part 5 can receive the supporting effect of first lath 3 and second lath 8 both, more firm to the condition of excessive buckling appears when can preventing PCB board main part 5 from installing.
