[0002] A pin header connector is an electronic component, usually made of metal, used to connect circuit boards or electronic components in electronic devices. It usually consists of two parts: a busbar and a male bar. The busbar is a row of connectors with pin holes, while the male bar is a connector with pins. The pin header connector connects by inserting the male bar into the pin holes in the busbar, thereby connecting electrical signal transmission or power supply to the corresponding device or circuit. Therefore, a pin header connector with a positioning function is proposed.

[0003] The traditional pin header connector connects the male row and the female row, but this method may cause the pins of the female row to bend due to the imprecise connection position, resulting in an unstable connection. Utility Model Content

[0016] 3.

[0025] Specifically, pressing the crank arm 6 drives the limit block 7 to move, and through the rebound of the spring 18, drives the crank arm 6 to rotate, so that the limit block 7 is stuck in the inside of the male row 8, and then the pin header above the busbar 1 is slid into the connecting groove inside the male row 8. At this time, the connection is completed, which prevents the pin header above the busbar 1 from bending due to inaccurate sliding position, resulting in an unstable connection.

[0026] Reference Figure 1 and Figure 4 The outer wall of the busbar 1 is fixedly connected with a second limit plate 11, and the second limit plate 11 is rotatably connected with a second rotating column 12 inside; the outer wall of the second rotating column 12 is fixedly connected with a connecting plate 13, and the outer wall of the connecting plate 13 is fixedly connected with a concave block 14; the outer wall of the concave block 14 is provided with a fixing groove 15, and the outer wall of the limit block 7 is slidably connected to the inner wall of the fixing groove 15; the lower surface of the concave block 14 is fixedly connected with a third rotating column 16, and the outer wall of the third rotating column 16 is rotatably connected with a clamping block 17;

[0027] Specifically, the rotating concave block 14 drives the connecting plate 13 to rotate, so that the concave block 14 covers the top of the pin headers above the busbar 1, so that all the pin headers are covered by the inside of the concave block 14, and then the clamping block 17 is rotated to clamp the clamping block 17 on the inner wall of the limiting groove 10, so as to achieve the effect of protecting the pin headers above the busbar 1 when not in use.

[0028] Reference Figure 1 , Figure 2 and Figure 4 The outer wall of the clamping block 17 is slidably connected to the inner wall of the limiting groove 10, and the outer wall of the recessed block 14 is attached to the outer wall of the busbar 1; the outer wall of the recessed block 14 is attached to the upper surface of the busbar 1;

[0029] Specifically, the curved arm 6 is loosened so that the outer wall of the curved arm 6 is stuck in the fixing groove 15 to achieve the effect of protecting the curved arm 6 .

[0030] Working principle: When the connector needs to be used, first push the slider 3 to the top of the groove 2 and press the crank arm 6. The crank arm 6 rotates through the first rotating column 5 fixed by the first limiting plate 4. The rotation of the crank arm 6 drives the limiting block 7 to move. Through the rebound of the spring 18, the movable crank arm 6 rotates to make the limiting block 7 stuck in the inside of the male row 8. Then the pin header above the busbar 1 slides into the connecting groove inside the male row 8. At this time, the connection is completed to prevent the pin header above the busbar 1 from bending due to inaccurate sliding position, resulting in unstable connection. When the busbar 1 and the male row 8 are connected, since the sliding distance of the slider 3 inside the busbar 1 is limited, the pin header slides into the connecting groove inside the male row 8 a certain distance, preventing the pin header from being damaged due to excessive or insufficient sliding. When the busbar 1 does not need to be connected, rotate the concave block 14, and the concave block 14 drives the connecting plate 13 Rotate, the connecting plate 13 rotates through the second rotating column 12 fixed by the second limiting plate 11, pressing the crank arm 6, and the crank arm 6 drives the limiting block 7 to move. At this time, the concave block 14 covers the top of the pin header above the busbar 1, so that the pin header is completely covered by the inside of the concave block 14, and then the clamping block 17 fixed by the third rotating column 16 is rotated to make the clamping block 17 clamped on the inner wall of the limiting groove 10 inside the fixed block 9. At this time, the crank arm 6 is released, so that the outer wall of the crank arm 6 is clamped in the inside of the fixed groove 15, so as to achieve the effect of protecting the pin header above the busbar 1 when it is not needed. The connector can not only prevent the pin header above the busbar 1 from bending due to inaccurate sliding position, resulting in unstable connection, but also achieve the effect of protecting the pin header above the busbar 1 when it is not needed. Finally, it can also achieve the effect of damaging the pin header due to excessive or insufficient sliding and increasing the service life of the connector.
