According to the rapid development of today's technology, more sophisticated and more complex electrical appliances or electronic products, such as computer equipment, audio, video recorders and other electrified new products continue to ask the market for people to use, and the internal circuit is usually extremely complicated. The efficiency is really satisfactory, but most of the electrical and electronic products related to electricity today must be equipped with a circuit board. In a limited space, in order to avoid the contact of the circuit, the condition of the short-circuit burning machine is usually on the circuit board. Between the circuit board or the chassis and the circuit board, the spacers are used for isolation because of the safety considerations. However, in the conventional way, the circuit board is positioned in the body, and the circuit board is assembled on the metal casing to have a plurality of On the screw hole of the screw hole, the through hole is reserved for each screw hole column on the circuit board regardless of the screw hole column. When installing the circuit board, the through hole is aligned with the thread hole, and then The screw is fixed to each screw lock fixed circuit board. However, in general, the number of fixing screws on the circuit board of the computer is very large, if the computer case factory When selling to a different PC manufacturers, PC manufacturers that will need to be installed according to different functions and different circuit boards. In addition, users When replacing a more efficient circuit board or performing maintenance, the disadvantage of the conventional circuit board fixing method is that it is necessary to assemble or remove all the screws one by one by using a power tool or a hand tool; or another conventional card post for The upper part of the body is provided with elastic claws, which can be fastened to the hole wall of the positioning hole of the printed circuit board, but if the clamping post is used, the printed circuit board needs to be buckled or pulled apart from each of the clamping posts, disassembled and assembled. It is also time consuming and inconvenient; therefore, the conventional method is inconvenient and time consuming in the installation and removal of the circuit board. Therefore, how to solve the lack of the use is the place for those who are engaged in this industry to improve.

Therefore, the creators have been concerned about the time-consuming and inconvenient problems associated with the installation and removal of fixed electrical boards. The collection of relevant information has been evaluated and considered by many parties, and the company has been using the years of R&D experience in this industry. This type of new patent for the rapid positioning of the board-to-board rapid positioning device was born.

The main purpose of the creation is that the spacer is fixed to the first plate body, and the second plate body is separated from the upper surface through the base portion, and the hollow body of the buckle body in the assembled snap body, the spring and the sliding sleeve is The head end of the spacer is pushed to elastically deform the arched elastic piece of the buckle body, and the fastening part is inserted into the buckle groove of the spacer column to be positioned. When disassembling, the sliding sleeve is pulled upward to make the spring The squeezing deformation is performed, and the ring convex portion of the sliding sleeve slides upward to abut against the positioning portion of the spring button body, and the fastening portion is inclined outwardly from the elastic piece to be located in the retreat space, thereby being separated from the spacer column body. Outside the buckle groove, it is easy to operate, securely assembled and positioned.
