[0001] This utility model belongs to the field of electrical connection device technology, and in particular relates to a vehicle diagnostic adapter. Background Technology

[0002] D-Sub (D-subminiature) diagnostic adapters are used to connect automotive diagnostic equipment to vehicles, enabling signal transfer between the diagnostic equipment and the vehicle. In related technologies, D-Sub connectors typically include a housing, a retaining element, and contacts. The retaining element secures the contacts within the housing. The contacts, usually male and female, are key components for achieving electrical connection. The number and layout of the male and female pins are determined based on different models and application requirements. Traditional D-Sub diagnostic adapters typically only include a single signal channel formed between the male and female pins, enabling only one type of signal transfer, resulting in poor flexibility and compatibility. Utility Model Content

[0003] The technical objective of this invention is to provide a vehicle diagnostic adapter, which aims to solve the problem of poor flexibility and compatibility of D-Sub diagnostic adapters in related technologies.

[0004] To solve the above-mentioned technical problems, this utility model is implemented as follows: a vehicle diagnostic adapter includes a housing, a PCBA board, a toggle switch, a first connector, and multiple second connectors. The PCBA board is fixed inside the housing, and the toggle switch, the first connector, and each of the second connectors are electrically connected to the PCBA board. One end of the housing has a first mounting port adapted to the first connector, and the other end has multiple second mounting ports adapted to the second connectors. The multiple second mounting ports are arranged at intervals, and the first connector is fixed to the first mounting port. Each second connector is fixed to a corresponding second mounting port, and each second connector is used to transmit different signals. The periphery of the housing also has a third mounting port adapted to the toggle switch, and the toggle switch is fixed to the third mounting port. The toggle switch is used to control the signal connection and disconnection between the first connector and each of the second connectors.

[0005] Furthermore, the number of second connectors is three.

[0006] Furthermore, the first connector is a 25-pin female connector, and the three connectors are a 9-pin male connector, a 15-pin male connector, and a 15-pin female connector, respectively.

[0007] Furthermore, positioning elements are connected to the outer periphery of the first connector and each of the second connectors, and positioning holes are provided on the positioning elements. The housing is also provided with mounting holes that are directly opposite to the positioning holes. The first connector and the housing, and each of the second connectors and the housing are fixed together by screws, which are inserted between the positioning holes and the corresponding mounting holes.

[0008] Furthermore, the positioning element includes a fixing piece connected to the positioning edge and a fixing piece perpendicularly connected to the positioning edge. The positioning edge is connected to the outer periphery of the first connector or the second connector, and the positioning hole is provided on the positioning edge. The fixing piece is fixed to the PCBA board, and each fixing piece is provided with multiple clearance holes. The pins of the first connector and each second connector pass through the corresponding clearance holes and connect to the PCBA board.

[0009] Furthermore, the housing includes an inner shell and an outer shell fitted outside the inner shell. The elasticity of the outer shell is greater than that of the inner shell, and the PCBA board is fixed to the inner shell.

[0023] Example:

[0024] like Figure 1-4As shown, in this embodiment, the vehicle diagnostic adapter includes: a housing 1, a PCBA board 2, a toggle switch 3, a first connector 4, and multiple second connectors 5. The PCBA board 2 is fixed inside the housing 1. The toggle switch 3, the first connector 4, and each of the second connectors 5 are electrically connected to the PCBA board 2. One end of the housing 1 has a first mounting port a that is adapted to the first connector 4, and the other end has multiple second mounting ports b that are adapted to the second connectors 5. The multiple second mounting ports b are arranged at intervals. The first connector 4 is fixed to the first mounting port a, and each of the second connectors 5 is fixed to the second mounting port b in a corresponding manner. Each of the second connectors 5 is used to realize the transmission of different signals. The periphery of the housing 1 is also provided with a third mounting port c that is adapted to the toggle switch 3. The toggle switch 3 is fixed to the third mounting port c. The toggle switch 3 is used to control the signal connection and disconnection between the first connector 4 and each of the second connectors 5.

[0025] Specifically, in this embodiment, both the first connector 4 and the second connector 5 can be D-Sub connectors. The vehicle diagnostic adapter is designed as a one-to-many splitter connection, and the connection of each connector is controlled by a toggle switch. This allows for flexible control of signal conduction on different lines, enabling users to quickly select the signal channel according to their needs, providing strong compatibility. It eliminates the need for a separate D-Sub interface for each device; a single interface (i.e., the first connector 4) is sufficient to meet multi-functional adapter requirements, greatly improving the functionality and ease of operation of the diagnostic interface while reducing usage and maintenance costs.

[0026] In this embodiment, the number of second connectors 5 is three. This design of the adapter structure allows for a "one-to-three" split-line switching function via the toggle switch 3, distributing the signal from one diagnostic interface to multiple modules or devices for switching. This enables signal switching between multiple devices (such as ECUs, upgrade modules, CAN diagnostic tools, etc.) without frequent connector plugging and unplugging, and ensures that the signal is transmitted to only one device at a time, avoiding signal conflicts or interference. In this embodiment, the toggle switch 3 makes the diagnostic interface of the adapter more scalable, allowing for easy addition of new signal channels or device support. For example, in this embodiment, four toggle switches 3 can be arranged side-by-side to control the on / off state of the signal channels corresponding to each connector. Specifically, the toggle switch 3 can be a C&K 7201 series product or a DP3T toggle switch from the NKK M2032 series products; no limitation is made here.

[0027] In this embodiment, the first connector 4 is a 25-pin female connector, and the three connectors are a 9-pin male connector, a 15-pin male connector, and a 15-pin female connector, respectively. Specifically, the first connector 4 is a D-Sub25 female connector, and the three connectors are a D-Sub9 male connector, an HD-Sub15 male connector, and an HD-Sub15 female connector, respectively. Exemplarily, in some specific implementations, the D-Sub25 female connector can be used as the main interface connecting the automotive diagnostic equipment and the vehicle, mating with the main connector of the diagnostic equipment as the main input and output entry point; the D-Sub9 male connector can be used to transmit specific low-speed signals or dedicated communication protocols (such as serial communication protocols, RS-232, etc.); the HD-Sub15 male connector can be used to transmit control signals or signals from specific functional modules of the diagnostic equipment to the target device; the HD-Sub15 female connector can be used to connect specific functional modules of the diagnostic equipment, such as video signal output, signal transmission, or control signal distribution. It is understood that in practical applications, the function of each D-Sub connector can be determined according to specific needs, and no limitations are imposed here.

[0028] In this embodiment, positioning elements d are respectively connected to the outer periphery of the first connector 4 and each of the second connectors 5. Positioning holes are provided on the positioning elements d, and the housing 1 is also provided with mounting holes corresponding to the positioning holes. The first connector 4 and the housing 1, and each of the second connectors 5 and the housing 1, are fixed together by screws 6, which pass through the positioning holes and the corresponding mounting holes. The screws 6 are used to achieve the connection between the first connector 4 and the housing 1, and between each of the second connectors 5 and the housing 1, ensuring the assembly stability of each connector in the device. The screws 6 used to fix the first connector 4 and the housing 1 can be screws that penetrate the entire housing 1 and the positioning elements d, and can be made of free-cutting steel, which has high hardness and stable performance.

[0029] In this embodiment, the positioning element d includes a positioning edge d1 connected to a fixing piece d2 perpendicularly connected to the positioning edge d1. The positioning edge d1 is connected to the outer periphery of the first connector 4 or the second connector 5, and a positioning hole is provided on the positioning edge d1. The fixing piece d2 is fixed to the PCBA board 2, and each fixing piece d2 has multiple clearance holes. The pins of the first connector 4 and each of the second connectors 5 pass through the corresponding clearance holes and connect to the PCBA board 2. Specifically, the positioning element d and the main body of the corresponding connector can be integrally formed, resulting in low processing cost and good structural connection stability. In some specific embodiments, the outer periphery of the housing 1 is provided with a limiting groove adapted to the positioning edge d1. That is, the first assembly port a and each of the second assembly ports b are respectively formed with limiting grooves adapted to the positioning edge d1. Each positioning edge d1 is embedded in the corresponding limiting groove and fixed to the housing 1 by screws 6. This assembly can improve the connection stability and sealing stability between the first connector 4, the second connector 5 and the housing 1. In this embodiment, the fixing piece d2 can be soldered to the PCBA board 2, and the clearance hole can be set to ensure good positioning. It can be seen that by setting the fixing piece d2, the assembly stability between the connector and the PCBA board 2 and the positioning accuracy of the pin can be improved.

[0030] In this embodiment, the housing 1 includes an inner shell 11 and an outer shell 12 sleeved on the outside of the inner shell 11. The elasticity of the outer shell 12 is greater than that of the inner shell 11. The PCBA board 2 is fixed to the inner shell 11. The first assembly port a, the second assembly port b, the third assembly port c, and the mounting hole respectively penetrate the inner shell 11 and the outer shell 12. The first housing 1 and the second housing 1 together enclose and form a limiting groove. This embodiment designs the structure of the housing 1 in this way, so that the housing 1 can take into account both flexible protection and rigid support functions. The outer shell 12 in this embodiment has greater elasticity, which can better absorb the energy brought by external impact, vibration or compression, thereby protecting the precision structure inside the connector and the stability of signal transmission. The inner shell 11 in this embodiment has relatively less elasticity, which increases the rigidity of the structure and ensures that the positions of the various components inside the connector are fixed and not easily deformed.

[0031] In this embodiment, both the inner shell 11 and the outer shell 12 are integrally molded parts, meaning the shell 1 is a one-piece molded rubber-coated structure, providing excellent sealing and waterproofing. In this embodiment, the inner shell 11 can be made of PE (polyethylene). PE has a low modulus of elasticity, providing stable support and mechanical strength, ensuring the internal structure of the shell 1 is not easily deformed. In this embodiment, the outer shell 12 can be made of PVC (polyvinyl chloride). PVC has better flexibility and impact absorption capacity, buffering external impacts and vibrations, enhancing the connector's impact resistance. Both PVC and PE are recyclable and inexpensive. Therefore, using these materials to construct the shell 1 structure ensures both the protective and impact-resistant properties of the shell 1, as well as the stability and electrical performance of the inner shell 11, making it a cost-effective and functionally optimized choice.

[0032] In this embodiment, an anti-slip part 121 is also provided on the outer periphery of the housing 12. The anti-slip part 121 can be a plurality of anti-slip protrusions distributed on the outer periphery of the housing 1. The anti-slip part 121 can improve the friction between the user's hand and the housing 1, making it convenient for the user to plug and unplug the adapter.

[0033] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
