Detailed Description

The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are some, but not all embodiments of the present invention. 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.

As shown in fig. 1 to 5, an assembled PCB comprises a PCB substrate 1, one side of the PCB substrate 1 is connected with a fixing block 2, one side of the fixing block 2 is provided with a groove 22 to form a step shape, the other side of the fixing block 2 is connected with a fixing strip 4, the fixing strip 4 corresponds to the horizontal position of the groove 22, the surface of the fixing strip 4 is connected with a block 5, the surface of the block 5 is provided with a blind hole 7, a limiting block 6 is inserted and connected into the blind hole 7, one end of the limiting block 6 extending out of the outside is in a shape of a cambered surface facing the side of the fixing strip 4 as a plane and the other end of the limiting block 6 is connected with the blind hole 7 through an elastic member, the surface of the groove 22 is provided with an accommodating groove 9 capable of accommodating the block 5, and the inner wall;

when the PCB needs to be spliced, one end of one PCB substrate 1 with the fixing strip 4 is clamped into the groove 22 of the other PCB substrate 1 downwards, the block 5 is inserted into the accommodating groove 9 at the moment, because the lower surface of the limiting block 6 is in the shape of an arc surface, when the lower surface of the limiting block 6 is subjected to upward reaction force, the limiting block 6 is subjected to component force moving towards the side surface, the limiting block 6 is retracted into the blind hole 7, the block 5 continues to move in the accommodating groove 9 until the limiting block 6 corresponds to the limiting groove 91, the limiting block 6 is reset and extends out of the limiting groove 91 under the action of the elastic element 8, because the upper surface of the limiting block 6 is a plane, the limiting block 6 cannot move upwards, so that the corresponding PCB substrate 1 cannot move upwards, and the two spliced PCB substrates 1 are firmly connected at the moment, and cannot move relatively in any direction, thereby accomplishing the splicing, having good firm connection effect, simple structure and convenient use.
