Description

Technical Field

[0001] This utility model relates to the field of vehicle controller technology, and in particular to a domain controller pin header connector structure. Background Technology

[0002] In recent years, with the national development of new energy vehicles and the continuous advancement of automotive intelligence, automobiles have shown a significant trend towards functional integration. Compared to the more complex structure of gasoline vehicles, new energy vehicles are easier to develop towards intelligence in terms of vehicle structure, power system, and handling. To meet the current demand for the integration of automotive electronic and electrical architecture from distributed to centralized, domain controllers integrating more architectural functions have emerged. Compared to the relatively decentralized traditional automotive ECU electronic control units, the demand for DCU domain controller wiring harness interfaces integrating multiple ECU electronic control units is also increasing. Traditional ECU connectors have fewer pins and can use existing mature connectors on the market. Integrated DCU domain controllers require a large number of pins, often exceeding 200 or even 300, resulting in fewer connector models to choose from. This necessitates the use of multiple connectors with fewer pins in combination, leading to higher connector costs. The DCU domain controller structure is also more complex, and there are also difficulties in assembly processes. Utility Model Content

[0003] To address the aforementioned issues, a domain controller pin header connector structure is provided, aiming to resolve the problems existing in the prior art.

[0004] The specific technical solution is as follows:

[0005] A domain controller pin header connector structure includes a pin header connector, a connector sleeve, a domain controller housing, and a PCB board. The pin header connector is soldered to the PCB board. The domain controller housing has multiple mounting holes. The connector sleeve is disposed at the mounting holes. The PCB board is disposed in the domain controller housing, and the pin header connector is inserted into the connector sleeve to form a connector assembly.

[0006] The aforementioned domain controller pin header connector structure also has the following features: the pin header connector includes multiple pin header bodies and a pin header fixing plate; the pin header fixing plate is evenly provided with fixing holes that correspond one-to-one with the pin header bodies; the pin header bodies are inserted into the corresponding fixing holes; and the pin header bodies are fixedly connected to the pin header fixing plate.

[0007] The beneficial effects of the above solution are: the pin header fixing plate can combine multiple pin headers into a complete pin header unit.

[0008] The aforementioned domain controller pin header connector structure also has the following features: the connector sheath includes a pin header connecting cylinder, which is disposed in the mounting hole; a partition is provided at the lower opening of the pin header connecting cylinder; and multiple insertion holes are provided on the partition for the pin header bodies to be inserted one by one. When the PCB board is completely inside the domain controller housing, the upper end of the pin header body is inserted into the corresponding insertion hole.

[0009] The beneficial effects of the above scheme are as follows: when the pin header body is inserted into the socket, a pin header array is formed in the pin header connecting tube; when the external connector is inserted into the pin header connecting tube, the pin header body is inserted into the external connector to form a connection.

[0010] The aforementioned domain controller pin header connector structure also has the following feature: the connector sheath further includes a connection locking structure, which is disposed at the upper opening of the pin header connecting tube. When an external connector is inserted through the upper opening of the pin header connecting tube, the connection locking structure cooperates with the external connector.

[0011] The beneficial effects of the above solution are: after the external connector is inserted into the pin header connecting cylinder, the connection locking structure can increase the friction between the external connector and the pin header connecting cylinder, preventing it from easily falling off.

[0012] The aforementioned domain controller pin header connector structure also has the following feature: multiple limiting ridges are provided on the side wall of the domain controller housing, and limiting slots corresponding to the limiting ridges are provided on the edge of the PCB board. When the PCB board enters the domain controller housing, the limiting ridges are precisely engaged in the limiting slots.

[0013] The beneficial effects of the above solution are: the limiting edge and the limiting groove cooperate with each other to prevent the PCB board from shaking in the domain controller housing.

[0014] In summary, the beneficial effects of this scheme are:

[0015] The domain controller pin header connector structure provided by this utility model simplifies the process by soldering the connector onto the PCB board and integrating the connector sheath onto the domain controller housing, thus solving the problem of difficult assembly of multiple connectors. The domain controller pin header connector structure provided by this utility model offers the advantage of simple assembly. Attached Figure Description
