Description

Technical Field

[0001] The utility model relates to the technical field of PCB connectors, in particular to a plug-in type PCB connector. Background Art

[0002] Printed circuit board connectors, also called PCB connectors, are a type of electronic connectors that are specifically used to connect and fix printed circuit boards. Printed circuit board connectors are used for connections between PCB boards, connectors, electronic connectors, communication equipment connectors, and for connecting communication equipment backplanes and daughter boards, industrial control backplanes and daughter boards, and precise and reliable connections. Generally, the female end is welded to the PCB board, and the male end is connected to the external wire. After the male end plug is inserted into the female end slot, the PCB board and the external wire are connected together.

[0003] After searching, it was found that the publication number is CN218732097U, and the name is plug-in PCB connector. The application proposes that the existing plug-in PCB connector has a relatively tight connection between the male plug and the female slot. Generally, the male plug is inserted into the female slot or the male plug is pulled out of the female slot by brute force, which is inconvenient to plug and unplug. At the same time, brute force plugging and pulling may easily pull the female end away from the welding position of the PCB board or break the male wire. By pressing the second moving rod on both sides, the second moving rod enters the card slot, and the inclined surface at the bottom of the card slot is pushed, so that the plug moves downward, and the first rubber pad and the second rubber pad are fully in contact, so that the insert and the plug are fixed and cannot be separated. When the plug needs to be unplugged, the first moving rod is pushed, and the inclined surface of the first moving rod is inserted into the bottom of the plug, thereby lifting the plug upward and separating the first rubber pad and the second rubber pad. At this time, the plug can be easily taken out of the plug barrel, and the device is plugged and unplugged by the first moving rod and the second moving rod, so as to avoid brute force plugging and unplugging to pull the welding piece away from the welding position of the PCB board or break the plug wire. However, this application not only needs to operate the plug for plugging and unplugging, but also needs to operate the first moving rod and the second moving rod, which is more troublesome. At the same time, the outer side of the plug barrel has more structures, the appearance structure is complicated, and it also occupies additional installation space, which is not conducive to improving the convenience of installation and use. Further improvements can be made.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
