[0002] A circuit board, or PCB, is short for Printed Circuit Board. Its surface is covered with electronic components and has terminals for connecting to external wiring harnesses. It is used for the transmission of circuit signals. On the top of the board, copper foil is engraved on the board using circuit printing technology to form conductors and install components.
[0003] The base plate of the circuit board is made of epoxy resin, and the terminals are mostly in the form of slots that can be inserted into the sleeves connected to the wire harness to transmit circuit signals. However, most of these terminals lack reinforcement structures and are only locked with screws. This requires carrying tools, and the screw shank may also damage the terminals or wire harness connecting pieces.
[0004] Now, a novel circuit board with terminal plug-in interface is proposed to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a circuit board with a terminal plug interface to solve the problem of lack of reinforcement at the terminals mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a circuit board with a terminal plug interface, comprising a board body, a groove provided at the front end of the board body, and a printed circuit module fixed on the surface of the groove, five sets of terminals longitudinally fixed on the left side of the front end of the printed circuit module, and a metal block fixed at the front end of the terminals, an interface movably sleeved on the outside of the metal block, and a wire harness fixed on the side of the interface, a rotating block movably connected above the terminals to the surface of the printed circuit module, and a movable groove provided inside the rotating block, a pull rod movably inserted into the movable groove, and a blocking block fixed behind the pull rod.
[0007] As a further technical solution of this utility model, the rotating block rotates at the front end of the terminal, and the pull rod pulls the blocking block along the inner wall of the movable groove.
[0008] As a further technical solution of this utility model, the ring on the right side of the interface is sleeved on the outside of the metal block, and the plug is fitted between the interface and the front end of the metal block.
[0009] As a further technical solution of this utility model, a slider is movably connected to the upper part of the main plate, and a cavity is provided between the two sides inside the slider. Steel balls are movably embedded in the lower two sides inside the slider. A screw hole is longitudinally provided inside the top of the slider, and a bolt is threaded into the screw hole. A second connecting hole is provided above the front end of the slider. A positioning hole is provided between the left and right sides of the top end of the main plate. A first connecting hole is provided at the upper left corner of the front end of the printed circuit module. A connecting wire is fixed between the first connecting hole and the second connecting hole. A limit block is fixed at the upper right corner of the front end of the printed circuit module, and two sets of through slots are provided in the limit block.
[0010] As a further technical solution of this utility model, the bolt is embedded between the screw hole and the positioning hole, and the slider slides left and right along the top of the plate body.
[0011] As a further technical solution of this utility model, the connecting line passes through the two sets of through slots inside the slider, and the top of the steel ball contacts the edge of the plate body.
[0012] As a further technical solution of this utility model, the four corners of the rear of the main body of the plate are respectively fixed with feet, and the four corners of the inside of the groove are respectively provided with slots.
[0013] As a further technical solution of this utility model, the foot is embedded in the slot, and the diameter of the foot matches the slot.
[0014] Compared with the prior art, the beneficial effects of this utility model are: the circuit board with terminal plug interface not only prevents the connecting piece from falling off the terminal and adjusts the position of the connecting structure, but also facilitates the stacking and transportation of multiple circuit boards.
[0015] (1) Five sets of terminals are fixed longitudinally on the left side of the front end of the printed circuit module. The wire harnesses that need to be connected to the main body of the board are connected to the outside of the metal block through the interface. There is no need to use screws or other things to fix them. Just rotate the movable connecting block above it so that the block is above the interface and the metal block. Then press the pull rod so that the pull rod passes through the movable slot and pushes the block to block the front of the interface and the metal block to prevent the interface from falling off the metal block. While completing the circuit connection, it is also convenient to manually disassemble and assemble.
[0016] (2) A slider is connected to the upper part of the plate body. The slider is moved along the upper part of the plate body and the groove. After aligning the screw hole and the positioning hole, the bolt is screwed in to lock. At this time, the right side of the connecting line at the first connection hole passes through the limiting block and passes through the two sets of through slots for limiting. The bottom end of the connecting line is fixed at the second connection hole, which can prevent the connecting line from swinging randomly. It passes through the second connection hole to install and fix the line to the outside. It can adjust the left and right position of the upper connecting structure.
[0017] (3) By setting slots at the four corners inside the groove, and leaving slots for matching feet at the four corners inside the front end of the groove, the main body of the board can be stacked together to avoid damage to the printed circuit module in the groove, and also to save storage space of the main body of the board, and to prevent the circuit board from colliding with each other and being worn during transportation, thus ensuring the integrity of the printed circuit module.
