A female header plastic guide angle 2025 is provided at the top of the female header plastic guide groove 2024. The outer diameters of the female header plastic positioning post one 2027 and the female header plastic positioning post two 2028 are different.

[0029] The present application provides a blade type pin header and a female header connector. The pin header is composed of pin header terminals, pin header plastics, and pin header harpoons. The female header is composed of female header terminals and female header plastics. First, the pin header terminals are inserted into the terminal jacks of the pin header plastics. For the convenience of terminal guiding, a positioning chamfer is designed at the head of the pin header terminals. At the same time, chamfers are also designed around the jacks of the pin header plastics. Under the action of the double chamfers, the pin header terminals are more easily inserted into the jacks of the pin header plastics. When the pin header terminals continue to be inserted forward into the jacks of the pin header plastics, the pin header terminal locking points will have an interference fit with the jacks of the pin header plastics. To achieve a high retention force of the pin header terminals, several pin header terminal locking points are designed, and a pin header terminal locking point groove is designed under each locking point. The main purpose of this groove is to absorb the excess glue when the terminal locking points have an interference fit with the jacks of the pin header plastics. When the terminal locking points have an interference fit with the terminal jacks, the excess glue will be squeezed into the pin header terminal locking point grooves. After being squeezed in, a reverse obstacle structure will be formed in the jacks of the pin header plastics. Under the action of the reverse obstacle structure, the retention force of the terminals will be further improved, thereby improving the quality of the entire pin header product. After the assembly of the pin header terminals is completed, the pin header harpoons are inserted into the harpoon jacks of the pin header plastics in the same way. For the convenience of the harpoons being smoothly inserted into the harpoon jacks of the pin header plastics, chamfers are also designed on the pin header harpoons. In addition, locking points are designed on the pin header harpoons, and the locking points are in the shape of barbs. Under the action of the barbs, the retention force of the pin header harpoons will be improved. In addition, positioning ribs are designed on the pin header harpoons, and the positioning ribs are inserted into the positioning grooves of the harpoon jacks of the pin header plastics. This can effectively ensure that the harpoons are not easily loosened up and down, thereby improving the assembly position accuracy of the harpoons.

[0030] In the same way, insert the female terminal into the female plastic socket. In order to facilitate the smooth insertion of the female terminal, the periphery of the female plastic socket is designed with chamfers. In order to increase the positioning accuracy of the female terminal, the female plastic is designed with female plastic positioning ribs on the female plastic. The positioning ribs cooperate with the U-shaped groove of the female terminal. When the female terminal is fully inserted into the female plastic socket, the female plastic positioning ribs will accurately position the U-shaped groove of the female terminal and limit the left and right shaking of the female terminal. In order to further improve the safety of the female terminal in the female plastic socket, the female terminal is designed with card points, which are also in the shape of barbs. Under the action of the barbs, the holding force of the female terminal will also be improved, thereby preventing the female terminal from falling off during work, especially in complex environments such as vibration. After the female terminal is assembled, the pin header can be plugged into the female terminal. After plugging in, the contact is achieved through the contact plane of the pin header terminal and the contact reinforcement rib of the female terminal. To improve the smoothness of plugging in, the pin header terminal is designed with plugging chamfers, and the head of the female terminal is also designed with chamfers. With the effect of double chamfers, the pin header and the female terminal are easier to insert. Similarly, due to the double chamfers, the pin header and the female terminal will not hit each other when plugging in. To further improve the reliability of plugging in between the pin header and the female terminal, a guide block is designed on the plastic of the pin header, and a guide groove is designed on the plastic of the female terminal. When the pin header is fully inserted into the header, When the pin header is inserted into the mother connector, the pin header plastic guide block is also fully inserted into the mother connector plastic guide groove. When the product is working, if it is impacted by external force, the guide block on the pin header plastic and the mother connector plastic groove will mainly bear the external force impact, thereby ensuring that the pin header terminal and the mother connector terminal are not deformed or have poor contact due to external force impact. In order to increase the smoothness of the insertion between the pin header plastic guide block and the mother connector guide groove, chamfers are also designed around the pin header plastic guide block and the mother connector guide groove. In order to increase the strength of the pin header plastic guide block, reinforcing ribs are also designed on the pin header plastic guide block. The reinforcing ribs can improve the overall strength of the guide block. In addition, in order to further improve the plugging and unplugging force between the pin header terminal and the female header terminal, the female header terminal is designed with female header terminal force arm support protrusions, and the support protrusions are distributed on the left and right blades of the female header terminal. When the pin header terminal is inserted into the female header terminal, the left and right blades of the female header terminal will be stretched open. At the same time, the position of the female header terminal force arm support protrusions will also move outward with the stretching of the left and right blades. After moving to a certain position, it will hit the female header plastic support wall. After hitting it, the left and right blades will stop stretching. At this time, when the pin header terminal continues to be inserted downward, the left and right blades of the female header terminal will be clamped tighter under the reaction force of the female header terminal force arm support protrusions and the female header plastic support wall, thereby improving its plugging and unplugging force.

[0031] The pin header and the female header will ultimately be installed on the PCB board and soldered. Their soldering parts are all solder feet. To improve the accuracy of the soldering position, there are female header plastic positioning posts 1 and 2 designed on the female header plastic. Among them, the outer diameters of the female header plastic positioning posts 1 and 2 are different. The difference can effectively prevent misoperation. When inserted reversely, it cannot be smoothly inserted into the PCB board, thus effectively avoiding the inability to correctly insert the pin header and the female header due to reverse insertion. In addition, to improve the efficiency of inserting the pin header and the female header into the PCB board, there are insertion board guiding angles designed on the solder feet of the pin header terminals and the female header terminals. Under the action of the guiding angles, the product is more conducive to being smoothly inserted into the PCB. To completely avoid the short-circuit phenomenon caused by tin infiltration between two adjacent terminals after soldering, there is also a pin header plastic anti-tin infiltration rib designed on the pin header plastic. Under the action of the anti-tin infiltration rib, the soldering tin between two adjacent terminals will be completely separated by the rib, thus avoiding the occurrence of short-circuit defects.

[0032] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
