Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically to a vertically mounted automotive tailgate connector with pin headers. Background Technology

[0002] The tailgate connector is an electronic component used to connect the electrical components of the tailgate to the vehicle's main circuitry. It is mainly used to transmit power and signals to ensure the proper functioning of the tailgate.

[0003] In existing automotive tailgate connectors, the pin header connection structure is mostly a simple upright type. The pin header lacks a precise positioning structure, which makes it easy to misalign when soldering to the circuit board, resulting in poor circuit connection. Furthermore, under the frequent vibration of the automotive tailgate, the pin header is prone to loosening, making it difficult to meet the requirements of automotive tailgate for connector stability and assembly precision. At the same time, the pin header and the insulating base are only connected by interference fit. After reflow soldering, the pin header and the insulating base are prone to loosening due to temperature stress and other factors. Utility Model Content

[0004] The purpose of this invention is to provide a vertically mounted automotive tailgate connector with pin headers to solve the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vertical connector for a car tailgate with pins and posts, comprising an insulating base, a through-hole disposed on the insulating base, and pins inserted into the through-hole. The bottom of the insulating base is integrally formed with symmetrical positioning posts, one end of which is provided with a tapered portion. Both sides of the pins are provided with dot-shaped protrusions, which abut against the inner sidewall of the through-hole. The top of the pins is equipped with a suction cap.

[0006] As a preferred embodiment of this utility model, the pins are distributed in two rows along the length of the insulating base, and the two rows of pins are staggered.

[0007] As a preferred embodiment of this utility model, the inner wall of the suction cap is provided with a clamping part.

[0008] As a preferred embodiment of this utility model, the bottom of the pin header is bent to form pins.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model solves the problem of easy pin displacement when soldering to the circuit board by cooperating with the positioning post and the positioning hole of the circuit board, thereby improving the assembly accuracy and soldering reliability, reducing the defect rate, and enhancing the overall structural strength of the connector. It can adapt to the high-frequency vibration conditions of the car tailgate and prevent the pins from loosening. The dotted protrusions significantly increase the fixing force between the pins and the insulating base. When affected by temperature stress after reflow soldering, the pins are not easy to loosen, ensuring long-term stable circuit connection, reducing the probability of after-sales failure, and the staggered distribution of the pins can better adapt to the narrow space and complex wiring of the car tailgate, improve space utilization, and facilitate later maintenance and repair.

[0016] 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.

[0017] Please see Figures 1 to 5This utility model provides a technical solution: a vertically mounted automotive tailgate connector with pin headers, comprising an insulating base 1, a through-hole 7 disposed on the insulating base 1, and pin headers 2 inserted into the through-hole 7. The pin headers 2 are made of tin-plated brass, possessing both good conductivity and bending strength. The bottom of the insulating base 1 has symmetrically integrally formed positioning posts 5. The positioning posts 5 and the insulating base 1 are integrally injection molded, making the connection between the two more secure and convenient for production. The material is a high-temperature resistant and impact-resistant engineering plastic. The positioning posts 5 are used to mate with positioning holes on the circuit board, thereby positioning the connection between the insulating base 1 and the circuit board. This not only prevents the pin headers 2 from shifting during soldering but also prevents the pin headers from loosening under frequent vibration. One end of the positioning post 5 has a tapered portion 6, which allows... The positioning post 5 is easier to insert into the positioning hole on the circuit board. Both sides of the pin header 2 are provided with dot-shaped protrusions 8. The dot-shaped protrusions 8 can increase the friction between the pin header 2 and the insulating base 1, significantly increasing the fixing force between the pin header 2 and the insulating base 1, and avoiding the loosening between the pin header 2 and the insulating base 1 due to temperature stress after reflow soldering. The dot-shaped protrusions 8 abut against the inner side wall of the socket 7. The top of the pin header 2 is detachably equipped with a suction cover 3. On the SMT production line, the pick-and-place machine accurately picks up the connector from the feeder and places it on the circuit board through the suction nozzle. Due to the structure of the connector pin header 2, the pick-and-place machine cannot pick it up. Therefore, the suction cover 3 can provide a flat and stable suction surface, so that the pick-and-place machine can easily and accurately complete the suction action, thereby improving production efficiency and accuracy.

[0018] Among them, the pin header 2 is distributed in two rows along the length of the insulating base 1, and the two rows of pin header 2 are staggered. The staggered layout can better adapt to the narrow space and complex wiring of the rear tailgate of the car, improve the space utilization rate, and facilitate later maintenance and repair.

[0019] The inner wall of the suction cover 3 is provided with a clamping part 4, which allows the suction cover 3 to be firmly installed on the outside of the pin header 2, preventing the suction cover 3 from separating from the pin header 2 when the connector is moved through the suction cover 3.

[0020] The bottom of the pin header 2 is bent to form a pin 9, which is used to solder to the circuit board pads to increase the contact area between the pin 9 and the circuit board, making the soldering of the pin header 2 more secure.

[0021] Specifically, during assembly, the equipment presses the pin header 2 into the insulating base 1, then bends the bottom of the pin header 2 by 90 degrees to form the pin 9, and then assembles the suction cap 3 onto the top of the pin header 2. During soldering, the automated equipment picks up the connector through the suction cap 3, aligns the positioning post 5 with the positioning hole on the circuit board, places the connector in place, and then uses reflow soldering to solder the pin 9 to the circuit board pads. During the reflow soldering process, the dotted protrusions 8 make the insulating base 1 and the pin header 2 more firmly fixed, reducing the risk of the pin header 2 loosening. After the connector is soldered to the circuit board, the suction cap 3 is removed.
