[0002] The vehicle's computer, also known as the electronic control unit (ECU), is a core control unit in a car, primarily responsible for the vehicle's driving status and various functions. The vehicle computer works in conjunction with connectors, which consist of pins and a substrate. The pins are elongated and pass through the substrate; one end of the pin is soldered to the PCB, while the other end plugs into other connectors within the vehicle computer. The pins provide power and transmit signals to the vehicle computer. During use, the pins are prone to breaking at the base, resulting in a relatively short lifespan. Utility Model Content

[0003] The purpose of this invention is to provide a vehicle computer connector that strengthens the protection of the PIN pin root, prevents the PIN pin from being broken, and extends its service life.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] A vehicle computer connector includes a base and PIN pins. The base includes a substrate, a first quadrangular truncated pyramid, and a second quadrangular truncated pyramid. The first and second quadrangular truncated pyramids are located on opposite sides of the substrate. The substrate covers the middle portion of the PIN pin. The two ends of the PIN pin are a soldering end and a plug-in end, respectively. The soldering end passes through the center of the first quadrangular truncated pyramid, and the first quadrangular truncated pyramid covers the root of the soldering end. The plug-in end passes through the center of the second quadrangular truncated pyramid, and the second quadrangular truncated pyramid covers the root of the plug-in end.

[0006] As an optional technical solution, the PIN pin has a limiting part in the middle, and the substrate is injection molded with plastic around the limiting part.

[0007] As an optional technical solution, the limiting part is a protrusion.

[0008] As an optional technical solution, the substrate has a through hole in the middle.

[0009] As an optional technical solution, the first quadrangular frustum includes four first side surfaces surrounding the periphery of the welding end, the upper edge of the first side surface is connected to the welding end, and the lower edge of the first side surface is connected to the substrate.

[0010] The second quadrangular frustum includes four second side surfaces surrounding the periphery of the plug-in end, the upper edge of the second side surface being connected to the plug-in end, and the lower edge of the second side surface being connected to the substrate.

[0011] As an optional technical solution, the substrate is provided with a limiting platform on the side where the first quadrangular frustum is located, and the limiting platform is higher than the first quadrangular frustum in the extension direction of the welding end.

[0012] As an optional technical solution, the substrate is provided with a positioning post on the side where the first quadrangular frustum is located.

[0013] As an optional technical solution, the PIN pin is a power connector;

[0014] Alternatively, the PIN pin may be a signal pin;

[0016] As an optional technical solution, in the same power pin, there is one plug-in end and two solder ends, and the connection position between the plug-in end and the two solder ends is covered by the substrate.

[0017] As an optional technical solution, the base is made of plastic injection molding.

[0018] The beneficial effects of this utility model are:

[0019] This utility model provides a vehicle computer connector, which includes a base and PIN pins. The base includes a substrate, a first quadrangular truncated pyramid, and a second quadrangular truncated pyramid. The first and second quadrangular truncated pyramids are located on opposite sides of the substrate. The substrate covers the middle of the PIN pin. The two ends of the PIN pin are a soldering end and a plug-in end, respectively. The soldering end passes through the center of the first quadrangular truncated pyramid, and the first quadrangular truncated pyramid covers the root of the soldering end. The plug-in end passes through the center of the second quadrangular truncated pyramid, and the second quadrangular truncated pyramid covers the root of the plug-in end.

[0020] When the vehicle computer connector is soldered onto the PCB board, the soldering end of the PIN pin is subjected to soldering force. Because this invention uses a first quadrangular truncated pyramid surrounding the root of the soldering end, it strengthens the root and prevents the soldering end from breaking off at the root. Simultaneously, due to the limiting effect of the first quadrangular truncated pyramid, the substrate cannot adhere to the surface of the PCB board, forming a soldering space between the substrate and the PCB board. Solder can enter this soldering space, ensuring the connection strength between the vehicle computer connector and the PCB board. When the vehicle computer connector is plugged into other connectors of the vehicle computer, the insertion end of the PIN pin is subjected to insertion force. Because this invention uses a second quadrangular truncated pyramid surrounding the root of the insertion end, it strengthens the root and prevents the insertion end from breaking off at the root.

[0035] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0036] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0037] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0038] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0039] like Figures 1 to 11 As shown, the vehicle computer connector provided in this embodiment includes a base 1 and a PIN pin 2. The base 1 includes a substrate 11, a first quadrangular truncated pyramid 12, and a second quadrangular truncated pyramid 13. The first quadrangular truncated pyramid 12 and the second quadrangular truncated pyramid 13 are located on both sides of the substrate 11. The substrate 11 covers the middle part of the PIN pin 2. The two ends of the PIN pin 2 are a soldering end 21 and a plugging end 22, respectively. The soldering end 21 passes through the center of the first quadrangular truncated pyramid 12, and the first quadrangular truncated pyramid 12 covers the root of the soldering end 21. The plugging end 22 passes through the center of the second quadrangular truncated pyramid 13, and the second quadrangular truncated pyramid 13 covers the root of the plugging end 22.

[0040] When the vehicle computer connector is soldered onto the PCB board, the soldering end 21 of the PIN pin 2 is subjected to soldering force. Since this embodiment uses a first quadrangular truncated pyramid 12 surrounding the root of the soldering end 21, it strengthens the root of the soldering end 21 and prevents the soldering end 21 from breaking off from the root. At the same time, due to the limiting effect of the first quadrangular truncated pyramid 12, the substrate 11 cannot be attached to the surface of the PCB board, and a soldering space is formed between the substrate 11 and the PCB board. Solder can enter the soldering space to ensure the connection strength between the vehicle computer connector and the PCB board. When the vehicle computer connector is plugged into other connectors of the vehicle computer, the insertion end 22 of the PIN pin 2 is subjected to insertion force. Since this embodiment uses a second quadrangular truncated pyramid 13 surrounding the root of the insertion end 22, it strengthens the root of the insertion end 22 and prevents the insertion end 22 from breaking off from the root.

[0041] Optionally, a limiting portion 23 is provided in the middle of the PIN pin 2, and the substrate 11 is injection molded from plastic around the limiting portion 23. When producing the vehicle computer connector of this embodiment, the substrate 11 is obtained by injection molding from plastic around the limiting portion 23, which can strengthen the connection between the substrate 11 and the PIN pin 2 and prevent the PIN pin 2 from loosening.

[0042] In this embodiment, the limiting part 23 is a protrusion. In some other embodiments, the limiting part 23 is a limiting hole, which can be filled with plastic in the hot-melt state.

[0043] Optionally, a through hole 16 is provided in the middle of the substrate 11. During the curing process, the plastic changes volume and generates stress. In order to prevent cracking due to stress, this embodiment provides a through hole 16 in the middle of the substrate 11 to relieve stress.

[0044] In this embodiment, the first quadrangular frustum 12 includes four first side surfaces surrounding the welding end 21. The upper edge of the first side surface is connected to the welding end 21, and the lower edge of the first side surface is connected to the substrate 11. The length of the upper edge of the first side surface is less than the length of the lower edge of the first side surface. In some other embodiments, the upper edge of the first side surface is spaced apart from the welding end 21, and the lower edge of the first side surface is connected to the substrate 11.

[0045] In this embodiment, the second quadrangular frustum 13 includes four second side surfaces surrounding the plug-in end 22. The upper edge of the second side surface is connected to the plug-in end 22, and the lower edge of the second side surface is connected to the substrate 11. The length of the upper edge of the second side surface is less than the length of the lower edge of the second side surface. In some other embodiments, the upper edge of the second side surface is spaced apart from the plug-in end 22, and the lower edge of the second side surface is connected to the substrate 11.

[0046] Optionally, the substrate 11 is provided with a limiting stage 14 on the side where the first quadrangular frustum 12 is provided, and the limiting stage 14 is higher than the first quadrangular frustum 12 in the extension direction of the welding end 21.

[0047] When the vehicle computer connector is soldered onto the PCB board, the limiting stage 14 contacts the surface of the PCB board to prevent the substrate 11 from tilting up. At this time, the first quadrangular stage 12 does not contact the surface of the PCB board.

[0048] In this embodiment, multiple limiting platforms 14 are provided, and the multiple limiting platforms 14 are distributed at intervals on the surface of the substrate 11. When the vehicle computer connector is soldered onto the PCB board, the multiple limiting platforms 14 simultaneously contact the PCB board, so that the substrate 11 and the PCB board are kept parallel to each other, preventing the substrate 11 from tilting.

[0049] Optionally, the substrate 11 may also have a positioning post 15 on one side where the first quadrangular frustum 12 is located. The positioning post 15 can be inserted into the positioning hole of the PCB board to pre-position the substrate 11. In this embodiment, two positioning posts 15 are provided.

[0050] Optionally, the base 1 is made of plastic injection molding. In this embodiment, the substrate 11, the first quadrangular frustum 12, the second quadrangular frustum 13, the limiting stage 14, and the positioning post 15 are made of plastic integral injection molding.

[0051] like Figures 4 to 6 As shown, in some embodiments, PIN pin 2 is a power pin, and there are multiple power pins.

[0052] like Figures 1 to 3 As shown, in some other embodiments, PIN pin 2 is a signal pin, and there are multiple signal pins.

[0053] like Figures 7 to 11 As shown, in some other embodiments, there are multiple PIN pins 2, some of which are power pins and others are signal pins.

[0054] Optionally, in the same power connector, there is one plug-in end 22 and two solder ends 21, and the connection between the plug-in end 22 and the two solder ends 21 is covered by the substrate 11. A power connector has two solder ends 21, which can ensure the connection strength between the power connector and the PCB board and improve the current overload capacity of the power connector.

[0055] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
