The insertion ends of the plurality of pins are exposed outside the hollow housing and electrically connected to the PCB board. The wiring ends of the plurality of pins are located inside the hollow housing and electrically connected to signal lines. The robust structure includes a grounding plate, which protrudes from the insertion portion of the hollow housing and is inserted into the PCB board.

Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0028] In one embodiment of this utility model, such as Figures 1-4As shown, a robust pin header connector is provided, including a hollow housing 1, a robust structure 2, and a plurality of pins 3. The hollow housing 1 has through holes 11 corresponding to the plurality of pins. The pins 3 have protrusions 31 at the mating points with the through holes 11. The insertion ends of the plurality of pins 3 are exposed outside the hollow housing 1 and electrically connected to a PCB board 4. The wiring ends of the plurality of pins 3 are located inside the hollow housing 1 and electrically connected to signal lines. The robust structure 2 includes a grounding plate 21, which protrudes from the insertion portion of the hollow housing 1 and is inserted into the PCB board 4. The hollow shell 1 is fixedly connected to the PCB board 4 via the grounding plate 21, thereby preventing the hollow shell 1 from flipping relative to the PCB board 4 using the solder joint of the pin 3 as a fulcrum in the plug-in state, which is beneficial to improving the safety and stability of the connector during use. The pin 3 is connected to the through hole 11 through the protrusion 31, which increases the mating area between the pin 3 and the through hole 11, thereby improving the stability of the pin 3 connection and reducing the possibility of the pin 3 becoming loose. Specifically, this embodiment also provides a PCB board 4, which has a socket 41 corresponding to the pin 3, a slot 42 corresponding to the grounding plate 21, and a notch 43 corresponding to the limiting plate 22. The slot 42 is rectangular and extends along the length of the hollow shell 1, and the notch 43 is rectangular and extends along the width of the hollow shell 1.

[0029] In one embodiment of this utility model, such as Figures 2-3 As shown, two grounding plates 21 are provided, arranged along the length of the hollow housing 1, providing a clamping force in the width direction. Specifically, the grounding plate 21 is inserted into the slot 42 of the PCB board 4 in its height direction, extends along the length of the hollow housing 1 on its long side, and corresponds to the width of the slot 42 on its short side. This structure of the long side of the grounding plate 21 provides a larger contact area between the hollow housing 1 and the PCB board 4 in its width direction, thus preventing the hollow housing 1 from flipping left and right using the solder joint of the pin 3 as a fulcrum during use, greatly improving the stability of the machine.

[0030] In one embodiment of this utility model, such as Figures 2-3 As shown, the grounding piece 21 includes a first piece 211 and a second piece 212 connected together. The interlocking portion of the hollow housing 1 has an assembly groove 12 adapted to the first piece 211. The first piece 211 is connected to the assembly groove 12 by riveting. The second piece 212 is exposed in the interlocking portion of the hollow housing 1 and interlocks with the PCB board 4. The structure is simple and easy to manufacture.

[0031] In one embodiment of this utility model, such as Figures 2-3As shown, the stabilizing structure 2 also includes a pair of limiting pieces 22. The pair of limiting pieces 22 are arranged along the width direction of the hollow housing 1 and can provide a fastening force in the length direction of the hollow housing 1. Specifically, the limiting pieces 22 are fitted into the notch 43 of the PCB board 4 in the height direction, extend along the width direction of the hollow housing 1 in the length direction, and correspond to the width of the notch 43. Thus, the long side structure of the limiting pieces 22 provides a larger contact area between the hollow housing 1 and the PCB board 4 in the length direction, thereby preventing the hollow housing 1 from flipping back and forth with the solder joint of the pin 3 as a fulcrum during use. Combined with the grounding piece 21 in this embodiment, bidirectional limiting and fastening are achieved, further improving the stability of the connector mounted on the PCB board 4.

[0032] In one embodiment of this utility model, such as Figures 2-3 As shown, a pair of limiting pieces 22 are integrally formed at both ends of the hollow shell 1 and extend to one end close to the PCB board 4, with their ends interlocking with the PCB board 4. Specifically, the limiting pieces 22 are integrally formed on the outer side of the hollow shell 1 by injection molding, which is simple in structure and easy to manufacture.

[0033] In one embodiment of this utility model, such as Figure 4 As shown, the protrusion 31 includes rectangular locking points protruding on both sides of the pin. Specifically, a single pin 3 has a total of eight locking points, arranged in groups of four. The two groups of locking points protrude opposite each other on both sides of the pin 3. The outward protrusion design achieves interference engagement between the pin 3 and the through hole 11, further increasing the contact surface between the pin 3 and the inner wall of the through hole 11, which helps to reduce the possibility of the pin 3 becoming loose.

[0034] In one embodiment of this utility model, such as Figures 3-4 As shown, it also includes a stop piece 32, which is disposed at the terminal of the plug 3, located inside the hollow housing 1, and abuts against the inner cavity wall. The stop piece 32 is triangular, with its base connected to the plug 3 and its right-angled side abutting against the inner cavity wall of the hollow housing 1. Specifically, four stop pieces 32 protrude outward from a single plug 3, and the four stop pieces 32 are arranged in a cross shape on the plug 3. By using the right-angled side of the stop piece 32 to abut against the inner cavity wall of the hollow housing 1, a resisting force is provided for the plug 3 in the direction of disengagement. The cross-shaped arrangement makes the inner end of the plug 3 evenly stressed, which helps to improve the stability of the connection between the plug 3 and the hollow housing 1.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
