Background technique

Although the history of mankind's invention of electricity is short, the speed of progress in the application and development of electricity has surpassed that of other sciences. It is not an exaggeration to say that modern people live in an electronic age. However, there is a necessary condition for the application of electricity, that is, the electricity needs to flow through a circuit to produce the required effects and functions, and many different components and devices often need to be connected to the circuit. The connection between the various components in the early electronic devices is to use wires to connect to each other, and the parts (component) and the wires of the parts are all welded by hand. Therefore, if it is a dense and complicated circuit, it needs to be connected. It takes considerable time and cost, and is prone to human error.

In modern times, the production technology of various electronic industries has advanced by leaps and bounds. The traditional time-consuming wiring work has been replaced by printed circuit board (P.C.B), because printed circuit board can not only reduce the space occupied by the circuit, but also eliminate the general The errors caused by hand-soldered circuits have replaced the original method of using wires to weld components, and are widely used in the electronics industry in conjunction with the use of various electronic components with small volumes.

The term printed circuit board (PCB) seems to be unfamiliar to no one in the electronics industry. It can be used not only as a support for parts in the circuit, but also as a connector for parts. It is to print electronic circuits on On a substrate, the substrate is covered with a thin layer of copper foil, and the required circuit is formed from this. Usually, the printing ink (ink) is deposited on the copper foil according to the circuit pattern, and then etched ( etched) to remove unnecessary copper, and the copper foil conductor left on the substrate after etching can be used to replace the function of the wire.

Furthermore, due to the rapid development and popularization of network devices, a system of printed circuit boards inserted vertically into a rack to form a cabinet has become a mainstream product in this market. A printed circuit board will run its own system, serve different user groups as specified, and can share resources to serve the same user group. The advantage of using this cabinet is that in addition to effectively saving space, it also has the advantages of reducing excessive power cords, network cables and keyboard cables.

However, the size of the printed circuit board generally occupies a considerable area. Therefore, it is often seen that when it is inserted into the cabinet, it is relatively thin and fragile in terms of support, guidance and fixing. At the same time, it is easy to make the printed circuit board The board shakes, and then when it is plugged with the pins of the connector on another printed circuit board at the rear end of the cabinet, it is often caused by the deflection of the printed circuit board, causing it to be crooked and loose, resulting in a crash, and even causing the The connectors on the printed circuit board are damaged and other situations occur. Therefore, if no effective support and alignment method is adopted to reduce the inconvenience and troubles caused by the user when replacing or inserting the printed circuit board, the user will often There are complaints about the fixed way of assembling the printed circuit board, so there is a need for improvement.

In view of the above-mentioned printed circuit board, because it occupies a considerable area, it will shake and deflect when inserted into the cabinet, and cannot be effectively supported, guided and fixed, and the connector pins on it will be blocked. Crashing, loosening, causing crashes, and even causing damage to the connectors on the printed circuit board and other defects. Therefore, based on the actual needs of the market and users, the designer has made long-term research and experiments, and finally Develop and design a component for guiding the printed circuit board into the device of the utility model.
