Abstract

The invention relates to the technical field of PCB, and discloses a PCB connecting and fixing device comprising a main PCB and an auxiliary PCB. The surface of the main PCB is provided with installing holes. Fixing devices are fixedly connected on the surface of the main PCB. A fixing plate is fixedly connected on one side of the main PCB. Rotating shafts are fixedly installed on the surface of the fixing plate. A clamp block is fixedly connected on the surface of each rotating shaft. A connecting plate is fixedly connected on one side, which is close to the main PCB, of the auxiliary PCB. The contact surface of the connecting plate and the fixing plate is provided with an auxiliary groove. According to the PCB connecting and fixing device, a convex block, the auxiliary groove and a sealing ring are arranged, the convex block and the auxiliary groove are mutually clamped when the clamp blocks and clamp grooves are mutually and adaptively clamped, the sealing ring deforms a lot under compression because of the hollow structure of the sealing ring, and the two sides of the sealing ring extend to the external side and contact the internal wall of the auxiliary groove in a sealing wayso that the sealing performance of the connecting part of the main PCB and the auxiliary PCB can be enhanced and the objectives of stable connection and convenient installation can be achieved.

Description

technical field [0001] The invention relates to the technical field of PCB boards, in particular to a connection and fixing device for PCB boards. Background technique [0002] The PCB board is a printed circuit board, also known as a printed circuit board, and is a provider of electrical connections for electronic components. Its development has a history of more than 100 years. Its design is mainly layout design. The main advantage of using circuit boards is that it greatly reduces wiring and assembly errors, and improves the automation level and production labor rate. [0003] In the PCB board industry, in order to reduce the difficulty of manufacturing, reduce the process flow, improve the performance of the PCB board and other purposes, the PCB board is decomposed into the main PCB board and the sub-PCB board, which are manufactured separately first, and then the main PCB board and the sub-PCB board are made separately. The secondary PCB boards are connected together. ...
