Technical Field

[0001] The utility model relates to the technical field of pin and female header connectors, in particular to an anti-falling pin and female header connector. Background Art

[0002] Pin header connectors are widely used in PCB circuit boards in electronics, electrical appliances, and instruments. Their function is to act as a bridge between blocked or isolated circuits within the circuit, and to take on the task of current or signal transmission. Female headers are a general-purpose connection device widely used in electronics, electrical appliances, and instruments. They mainly play the role of current or signal transmission. When used in conjunction with female headers, they form a board-to-board connection.

[0003] At present, the connection of existing pin and female header connectors is generally achieved by plugging and unplugging the pin headers and female headers of the pin header and the female header, without any other auxiliary fixing and locking structure. During use, the pin header and the female header are easily separated by external force, resulting in a circuit break. Utility Model Content

[0007] Preferably, grooves are provided at the four corners of the pressure plate, and the spring is welded inside the groove, and the spring is a compression spring.

[0008] By adopting the above technical solution, the arrangement of the groove allows the compressed spring to completely enter the interior thereof without affecting the overlap between the pressure plate and the pin header base.

[0009] Preferably, the side dimensions of the pressing plate are adapted to the side dimensions of the pin header base, and the thickness of the fixing block is twice the thickness of the pressing plate.

[0010] Preferably, there are two fixing blocks, which are respectively welded to the left and right sides of the mother-disc base, and the top surface height of the fixing blocks is smaller than the top surface height of the mother-disc base.

[0011] By adopting the above technical solution, the fixing block with a lower top surface height can make the pins connect with the sockets of the header base first, and then the plugboard will be plugged into the inside of the slot.

[0012] Preferably, the top of the female connector base is provided with a plurality of sockets, and the number of the pins is the same as the number of the sockets.

[0013] By adopting the above technical solution, the pins are inserted into the inside of the sockets, completing the docking between the pin header base and the female header base.

[0014] Preferably, the length of the inserting plate is adapted to the depth of the slot, the limiting plate is welded to one side of the inserting plate, the sum of the widths of the limiting plate and the inserting plate is adapted to the width of the slot, the slot is connected to the limiting groove, and the size of the limiting groove is adapted to the size of the limiting plate.

[0015] By adopting the above technical solution, when pressing the pressure plates on both sides to insert the pin into the inside of the socket, the insertion plate and the limit plate enter the inside of the slot at the same time. After releasing the pressure plate, the limit plate will enter the inside of the limit groove in the horizontal direction, thereby enhancing the stability of the connection between the pin header base and the mother header base.

[0016] Compared with the prior art, the utility model has the following advantages:

[0017] The anti-falling pin and female connector is provided with a limit plate, the end of the spring is fixedly connected to a pressure plate, the bottom of the pressure plate is fixedly connected to an inserting plate, one side of the inserting plate is fixedly connected to the limit plate, one side of the fixed block is provided with a slot, and one side of the slot is provided with a limit slot. When in use, the pressure plates on both sides of the pin header base are pressed to insert the pins into the inside of the socket, and the inserting plate and the limit plate enter the inside of the slot at the same time. After the pressure plate is released, the limit plate will enter the inside of the limit slot in the horizontal direction, thereby enhancing the stability of the connection between the pin header base and the female base. Even if the pin header base is pulled outward, it will not be separated from the female base, thereby achieving the purpose of preventing falling off. BRIEF DESCRIPTION OF THE DRAWINGS
