Description

Firmly connected spliced circuit board Technical Field The utility model relates to the technical field of circuit boards, in particular to a firmly-connected spliced circuit board. Background The spliced circuit board (PCB spliced board) is a circuit board combination which is formed by splicing a plurality of independent small-size circuit boards into a larger size through a specific mode, and the core of the spliced circuit board is to optimize the production flow, reduce the cost and improve the efficiency. The traditional spliced circuit board is fixed by a plug-in type interface or welding, and has the following defects: The plug is easy to loosen, namely, only the needle opening is in friction fit with the plug, and poor contact is easily caused by vibration or external force; therefore, a splicing scheme with flexibility, stability and easy maintenance is needed. Disclosure of utility model The object of the present utility model is to solve at least one of the technical drawbacks. Therefore, an objective of the present utility model is to provide a firmly connected spliced circuit board, which solves the problems mentioned in the background art and overcomes the shortcomings in the prior art. In order to achieve the above object, an embodiment of an aspect of the present utility model provides a firmly connected spliced circuit board, which includes a main board and an auxiliary board, wherein the auxiliary board is detachably connected above the main board, and a plurality of elements are mounted on the surfaces of the main board and the auxiliary board; A socket is fixedly connected to the edge of the surface of the main board, and a needle opening is integrated in the socket; the edge of the surface of the auxiliary plate is fixedly connected with a flexible belt, the end part of the flexible belt is fixedly connected with a plug, and the plug is provided with a plurality of needles and is inserted into the needle opening of the socket; The upper end face of the socket is fixedly connected with a layer of elastic pad, the upper end face of the socket is fastened with a pressing plate, two ends of the pressing plate are fastened with fastening heads, and the fastening heads are in threaded connection with the upper end face of the socket; the top fixedly connected with of clamp plate a plurality of fastening claw, the fastening claw is the form of buckling, the fastening claw colludes to press on the top surface of plug, the clamp plate below compresses tightly the elastic pad.
