[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1 - Figure 4 As shown, this embodiment provides an automotive connector female socket assembly, including a female socket body 1 and pins 2. The female socket body 1 includes a housing 3 and a mounting base 4. The mounting base 4 is fixedly installed on the lower end of the rear surface of the housing 3, and the lower surface of the mounting base 4 is flush with the lower surface of the housing 3.

[0026] A positioning platform 5 is fixedly connected to the middle of the upper inner wall of the outer shell 3. Guide grooves 6 are provided on both sides of the lower surface of the positioning platform 5. The positioning platform 5 and the interior of the outer shell 3 are provided with a snap-fit ​​groove 7 for corresponding to the snap-fit ​​at the upper end of the plug-in male head.

[0027] Both the rear surface of the housing 3 and the upper surface of the mounting base 4 are provided with multiple insertion slots 8 for mounting pins 2;

[0028] The pin 2 includes an inner pin 9, an outer pin 10 and a bend connecting part 11. The outer pin 10 is L-shaped. The end of the inner pin 9 near the mounting base 4 is connected to the outer pin 10 through the bend connecting part 11.

[0029] The rear surface of the mounting base 4 is provided with multiple positioning grooves 12 that are adapted to the outer needle part 10.

[0030] The above working principle: After passing through the housing 3 and the mounting base 4, the inner pins 9 of multiple pins 2 bend towards the lower surface of the housing 3 to form a bend connection 11, which connects to the outer pins 10, reducing space requirements and improving compactness. Furthermore, because the outer pins 10 are L-shaped, their axes are parallel to the axes of the inner pins 9, facilitating the soldering of multiple pins 2 to the wires and making the connection between the connector body 1 and the control board more convenient. This improves the structural stability between the connector body 1 and the control board to a certain extent. Under the action of the bend connection 11, the end of the inner pin 9 near the mounting base 4 and the end of the outer pin 10 near the housing 3 are set at a 90° angle, thereby preventing… Multiple pins 2 may become loose and unstable after prolonged use. The multiple positioning grooves 12 on the mounting base 4 can further position and restrain the external pins 10, allowing the multiple pins 2 to connect together and form a more stable whole. This prevents the multiple pins 2 from becoming skewed or deformed, ensuring the welding accuracy and stability of the multiple pins 2. When the female connector body 1 and the male connector are engaged, the positioning platform 5 and guide groove 6 work together to guide the engagement of the female connector body 1 and the male connector, and allow the upper end of the male connector to engage with the snap-fit ​​groove 7. This increases the stability and accuracy of the connection between the connector and the female connector, reduces the possibility of loosening during insertion and removal, and improves the safety of use.

[0031] To increase the stability and accuracy of the connection between the female connector body 1 and the male connector, an L-shaped anti-foolproof reinforcing rib 13 is fixedly connected to one inner wall of the outer shell 3, and a guide groove 14 is provided on the other inner wall of the outer shell 3. The L-shaped anti-foolproof reinforcing rib 13 and the guide groove 14 work together to increase the stability and accuracy of the connection between the female connector body 1 and the male connector, ensure accurate insertion, reduce the possibility of loosening of the connection between the connector and the female connector during insertion and removal, and improve the safety of use.

[0032] To facilitate the installation of the female connector body 1, a positioning baffle 15 is fixedly fitted on the front outer wall of the outer shell 3. A limiting groove 16 is opened at the lower end of the positioning baffle 15. The positioning baffle 15 plays a limiting role when the female connector body 1 is installed, ensuring the accuracy of the installation position of the female connector body 1, and making part of the outer shell 3 of the female connector protrude relatively, which facilitates the connection between the male connector and the female connector.

[0033] To ensure the stability of the plug-in female body 1 after installation, guide posts 17 are symmetrically fixedly connected to the lower surface of the outer shell 3, and mounting grooves 18 are provided on the upper surface of the outer shell 3. The two guide posts 17 enable the plug-in female body 1 to be quickly aligned with the control board when connected, and the mounting grooves 18 ensure the stability of the plug-in female body 1 when connected with the control board, preventing the plug-in female body 1 from becoming loose during long-term use.

[0034] To facilitate the installation of the plug-in female body 1 during operation, positioning rods 19 are symmetrically fixedly connected to both outer walls of the outer shell 3. Multiple positioning rods 19 are set behind the positioning baffle 15. When installing the plug-in female body 1, the multiple positioning rods 19 can quickly complete the connection between the plug-in female and the electrical control base, avoiding excessive alignment time between the connector and the electrical control board, which would affect the installation efficiency.

[0035] In addition, to ensure the service life of the main body 1 of the plug-in female connector, both the outer shell 3 and the mounting base 4 are made of plastic material, and the outer shell 3 and the mounting base 4 are integrally injection molded. The plastic material has good electrical insulation and arc resistance, and good controllability, which makes the manufacturing of the outer shell 3 and the mounting base 4 relatively convenient and inexpensive, reducing manufacturing costs. The good electrical insulation and arc resistance can increase the safety of the main body 1 of the plug-in female connector. The integrally injection molded outer shell 3 and the mounting base 4 can be processed in one step without the need for later assembly and debugging. The installation is easy and precise, and the overall stability is better, ensuring the service life of the outer shell 3 and the mounting base 4.
