A board-end connector power terminal

Abstract

This application provides a board-end connector power terminal, including a connecting body, a power signal interface, signal terminals, and power terminals. One end of the connector body is an interface end with a power signal interface, and the other end is a soldering end for connecting to a PCB board. The power signal interface has multiple evenly spaced signal terminals and two power terminals, with a shielding partition between the signal terminals and the power terminals. The two ends of the power terminals are a first power terminal and a second power terminal, with the first power terminal located inside the interface end and the second power terminal located at the soldering end, extending beyond the connecting body for soldering to the PCB board. The first and second power terminals are staggered, with the second power terminal closer to the signal terminals than the first power terminal, thus concentrating the power terminals and signal terminals at the soldering end. This power terminal adjusts the power terminal size, increasing the capacity to accommodate PCBA electrical components.

Description

Technical Field

[0001] This application belongs to the field of automotive connector technology, specifically relating to a power terminal for a board-end connector. Background Technology

[0002] While ensuring the strength and safety performance of automobiles, their functions are also increasing. To safely and effectively realize these functions, it is necessary to develop connector products that adapt to these functions and connect various wiring harnesses, providing effective power and signal connections for the vehicle's functions. PCBA (Printed Circuit Board Assembly) is a general term for printed circuit board assemblies, referring to functional modules assembled on a bare PCB board after component soldering. Its core processes include SMT surface mount technology (SMT) and DIP insertion, and it is widely used in consumer electronics, automotive electronics, and other fields. Due to the increasing market demand for enhanced PCBA functionality, the PCB board's capacity is facing challenges.

[0003] One end of the connector has a standard interface that can be plugged into a quick-connect interface, while the other end is soldered to the PCB board. The soldered end of the existing connector for connecting to the PCB board is the same size or very similar to the standard interface end, which requires a large amount of PCB board space and affects its capacity. Summary of the Invention

[0004] This application provides a board-end connector power terminal with a simple structure and reasonable function.

[0005] A board-end connector power terminal includes a connecting body, a power signal interface, signal terminals, and power terminals. One end of the connector body is an interface end with a power signal interface, and the other end of the connector body is a soldering end for connecting to a PCB board. The power signal interface has multiple evenly spaced signal terminals and two power terminals, and a shielding partition is provided between the multiple signal terminals and the two power terminals. The two ends of the power terminal are a first power terminal and a second power terminal, respectively. The first power terminal is located inside the interface end, and the second power terminal is located in the soldering end. The second power terminal extends outside the connecting body and is used for soldering to the PCB board. The first power terminal and the second power terminal are staggered, with the second power terminal being closer to the signal terminal than the first power terminal, so that the power terminal and the signal terminal of the soldering end are concentrated.

[0006] Furthermore, the power terminal is a sheet terminal structure, and the middle part of the power terminal is set with an inclined bending structure to connect the first power terminal and the second power terminal.

[0007] Furthermore, the signal terminal is a pin-type terminal structure, with a first signal terminal and a second signal terminal at its two ends. The first signal terminal is located inside the interface terminal, and the second signal terminal is located at the soldering terminal. The second signal terminal extends outside the connecting body for soldering to the PCB board.

[0008] Furthermore, the main body of the connection is an injection-molded plate structure with an integrally formed first signal interface and a power signal interface spaced apart at the interface end. The first signal interface and the power signal interface are different in size and are both industry standard interfaces for quick plugging. The first signal interface has multiple evenly spaced signal terminals.

[0009] Furthermore, the first signal interface and the power signal interface are provided with guide bars inside, and the guide bars are elongated protrusions in the same direction as the insertion and sliding.

[0010] Furthermore, a one-way slope limiting hook is provided on the outer wall of both the first signal interface and the power signal interface.

[0011] In summary, the technical solutions provided in the embodiments of this application have the following technical effects or advantages: This power terminal adjusts its size to be closer to the signal terminals, thereby reducing the space occupied on the PCB board and increasing the PCBA's capacity to accommodate electrical components.

[0017] To enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0018] A board-end connector power terminal includes a connection body 6, a power signal interface 4, a signal terminal 3, and a power terminal 2. See attached diagram. Figure 1 As shown, the connector body 6 is an injection-molded board structure. One end of the connector body is the interface end, where an integrally molded first signal interface 1 and a power signal interface 4 are spaced apart. The first signal interface 1 and the power signal interface 4 are of different sizes and are both industry-standard quick-connect interfaces. The other end of the connector body is the soldering end for connecting to the PCB board.

[0019] The first line interface has multiple evenly spaced signal terminals 3. The power signal interface 4 has multiple evenly spaced signal terminals 3 and two power terminals 2, and a shielding partition is provided between the multiple signal terminals 3 and the two power terminals 2.

[0020] See appendix Figure 2 As shown, signal terminal 3 is a pin terminal structure. The two ends of signal terminal 3 are signal first end 301 and signal second end 302, respectively. Signal first end 301 is located inside the interface end, and signal second end 302 is located at the soldering end. Signal second end extends to the outside of the connecting body 6 for soldering with the PCB board. The power terminal 2 is a chip terminal structure. The two ends of the power terminal 2 are a first power terminal 201 and a second power terminal 202, respectively. The first power terminal 201 is located inside the interface end, and the second power terminal 202 is located at the soldering end. The second power terminal 202 extends to the outside of the connecting body 6 for soldering to the PCB board. The first power supply terminal 201 and the second power supply terminal 202 are offset from each other, and the middle part of the power supply terminal 2 is set as an inclined bending structure to connect the first power supply terminal 201 and the second power supply terminal 202.

[0021] See appendix Figure 3 , 4 As shown, compared with the prior art, the second power supply terminal 202 in this embodiment is closer to the signal terminal 3 than the first power supply terminal 201, so that the power supply terminal 2 and the signal terminal 3 at the soldering end are set together, ensuring the original function is realized while occupying a smaller soldering space on the PCB board.

[0022] The first signal interface 1 and the power signal interface 4 are equipped with guide bars 7. The guide bars 7 are elongated protrusions with the same sliding direction as the plug, which can cooperate with the structure of the plug and play the role of limiting and guiding.

[0023] One-way slope limit hooks 5 are provided on the outer side walls of the first signal interface 1 and the power signal interface to ensure that the plug can be fixed after being inserted into the correct position.
