In this way, the common heavy-duty connector with automatic fastening function can be applied to the connection of cables in conventional application scenarios and environments of rail trains, and can be used in scenarios where they are frequently disassembled. The common heavy-duty connector with automatic fastening function includes a shell portion and a locking portion 2.

[0034] In the following description, reference will be made to Figures 1 to 9 The detailed structures of the housing portion and the locking portion 2 of the common heavy-duty connector with automatic fastening function are specifically described.

[0035] like Figures 1 to 5As shown, in an embodiment, the housing portion may include a first housing 101 and a second housing 102. The first housing 101 and the second housing 102 are connected to each other for the insertion of cables (not shown). During use, the first housing 101 can be used as a plug, and the second housing 102 can be used as a socket. The first housing 101 and the second housing 102 are respectively connected with cables, and the two are connected to realize the transmission of data and current. Since the common heavy-duty connector with automatic fastening function belongs to a rectangular connector, the first housing 101 and the second housing 102 can both be formed into a shell of a roughly rectangular parallelepiped structure, the first end of the first housing 101 can be a closed end, and a wire outlet hole 103 is provided on the side of the closed end for the insertion of cables, and the second end of the first housing 101 and the second housing 102 can both be formed into open ends for easy docking.

When the first shell 101 and the second shell 102 are locked, the separation handle 2024 is pulled to separate the hook 2021 from the fixed column 201. During the docking process of the first shell 101 and the second shell 102, the hook 2021 moves toward the direction close to the fixing column 201 until the hook 2021 is engaged with the fixing column 201, thereby achieving the fixing and locking of the first shell 101 and the second shell 102; if the first shell 101 and the second shell 102 are to be separated, the separation handle 2024 needs to be pulled to separate the hook 2021 from the fixing column 201. The common heavy-duty connector with automatic fastening function does not require manual operation during the locking process, and the first shell 101 and the second shell 102 can be directly docked to achieve locking. When separation is required, the separation handle 2024 can be pulled to achieve quick separation, and there is no need to use a handle for loading and unloading, and the loading and unloading process is also more convenient.

[0037] Preferably, if Figures 1 to 7As shown, in an embodiment, the sliding assembly may include a sliding member 202 and a fixing member 203, the fixing member 203 is disposed on the side of the first housing 101, the fixing member 203 includes a through hole 2033 and a sliding column 2032, and the sliding column 2032 is disposed on the side of the through hole 2033. The first end of the sliding member 202 is a hook 2021, and the second end of the sliding member 202 is a separation handle 2024. The hook 2021 and the separation handle 2024 are connected through a sliding plate 2026, the sliding plate 2026 is penetrated through the through hole 2033, and the sliding plate 2026 is provided with a sliding block 2025, and the sliding block 2025 slides along the sliding column 2032. The sliding plate 2026 can connect the hook 2021 and the separation handle 2024. After the sliding plate 2026 passes through the hole 2033, the hook 2021 and the separation handle 2024 are respectively located at both ends of the fixing member 203. At this time, the sliding block 2025 is sleeved on the sliding column 2032 to play a guiding role.

[0038] Preferably, if Figure 6 and Figure 7 As shown, in an embodiment, the sliding member 202 may include two hooks 2021, and the two hooks 2021 are respectively arranged at both ends of the sliding member 202. In this way, the sliding member 202 may include two sliding plates 2026, and the first ends of the two sliding plates 2026 are both hooks 2021, and the second ends of the two sliding plates 2026 are both separation handles 2024. The separation handle 2024 can be formed as an arc-shaped plate and connect the second ends of the two sliding plates 2026.

[0039] Preferably, if Figure 6 and Figure 7 As shown, in the embodiment, in order to ensure smooth sliding, the number of sliding posts 2032 can be two, and the two sliding posts 2032 can be arranged in parallel and at intervals on the fixing member 203, and the sliding plate 2026 can be arranged at the interval between the two sliding posts 2032, and the number of sliding blocks 2025 is also two accordingly, and the sliding blocks 2025 and the sliding posts 2032 are arranged one by one. In addition, when the number of sliding plates 2026 is two, the number of sliding posts 2032 can be four, and the four sliding posts 2032 are arranged in groups of two, and each group of sliding posts 2032 corresponds to one sliding block 2025.

[0040] Preferably, if Figures 1 to 7 As shown, in the embodiment, a spring 204 is provided on the outer periphery of the sliding column 2032, the first end of the spring 204 abuts against the fixing member 203, and the second end of the spring 204 abuts against the sliding block 2025. The setting of the spring 204 can realize the reset of the hook 2021. After pulling the separation handle 2024 to separate the first shell 101 and the second shell 102, the spring 204 can reset the sliding block 2025.

[0041] Preferably, if Figures 1 to 5 As shown, in the embodiment, the first housing 101 and the second housing 102 are butted against each other in the first direction, the hook 2021 is engaged with the fixed column 201 in the first direction, and the sliding assembly slides in the second direction. Here, the first direction and the second direction are different directions. In the embodiment, the first direction can be perpendicular to the second direction. In this way, the hook 2021 and the fixed column 201 can be locked in the first direction, and when separated, the user needs to pull the separation handle 2024 from the second direction.

[0042] Preferably, if Figures 1 to 7 As shown, in the embodiment, the locking portion 2 may include a first sliding assembly and a second sliding assembly, the first sliding assembly and the second sliding assembly are respectively arranged on both sides of the housing portion, and when separated, the first sliding assembly slides along the second direction, and the second sliding assembly slides in the opposite direction of the second direction.

Specifically, the sliding surface 2022 can be formed as an inclined surface. During the docking process of the first shell 101 and the second shell 102, the sliding surface 2022 slides along the outer surface of the fixing column 201. Figure 5 , Figure 5 The figure shows the state of the first shell 101 and the second shell 102 being docked. At this time, under the influence of external force (for example, the force applied by the user during docking), the sliding surface 2022 slides along the outer surface of the fixed column 201, driving the hook 2021 to slide to both sides (that is, the sliding block 2025 slides along the sliding column 2032), so that the outer surface of the fixed column 201 slides over the sliding surface 2022 and abuts against the abutting surface 2023. The abutting surface 2023 can be formed as a curved surface, and the bending angle of the curved surface corresponds to the outer surface of the fixed column 201, so that the fixed column 201 can be clamped on the abutting surface 2023. After the first shell 101 and the second shell 102 are docked, the curved surface abuts against the outer surface of the fixed column 201, thereby realizing the clamping of the hook 2021 and the fixed column 201.

[0044] Preferably, the hook 2021 may be formed as a 45° arrow-shaped component, that is, the angle between the sliding surface 2022 formed as an inclined surface and the horizontal plane is 45°.

[0045] Preferably, if Figure 6 and Figure 7 As shown, in the embodiment, the fixing member 203 is fixedly connected to the first housing 101 via a fixing screw 2031 arranged in the middle.

[0046] Preferably, if Figure 1 , Figure 2 , Figure 8 and Fig. 9 As shown, in the embodiment, the common heavy-duty connector with automatic fastening function further includes a connecting portion 3, which is arranged inside the shell part and is used for the cable to pass through.

[0047] Preferably, if Figure 1 , Figure 2 , Figure 8 and Fig. 9 As shown, in the embodiment, the connection part 3 may include a first connection component and a second connection component, the first connection component is arranged inside the first housing 101, and the second connection component is arranged inside the second housing 102. The first connection component can be used for passing the first cable, and the second connection component can be used for passing the second cable. When the first housing 101 and the second housing 102 are connected, the first cable and the second cable are connected, and data and current are transmitted.

[0048] Preferably, if Figure 1 , Figure 2 , Figure 8 and Fig. 9 As shown, in the embodiment, the first connection component and the second connection component both include: a bracket 301, a first cable passing portion 302, a second cable passing portion 303 and a third cable passing portion 304, and the bracket 301 is sleeved on the outer periphery of the first cable passing portion 302, the second cable passing portion 303 and the third cable passing portion 304 to fix the three. The first cable passing portion 302 can be used for passing and fixing the network cable, and the second cable passing portion 303 and the third cable passing portion 304 can be used for passing and fixing the current line.

[0049] Preferably, if Figure 1 , Figure 2 , Figure 8 and Fig. 9 As shown, in the embodiment, cable ties 305 are provided on both sides of the bracket 301 for shielding; and cable clamps 306 are provided at the ends of the first cable passing portion 302 for clamping the cables.

[0050] The use process of the common heavy-duty connector with automatic fastening function is as follows: Figure 3 and Figure 4 As shown, when the first shell 101 and the second shell 102 are docked, the user only needs to apply external force to dock the two shells, and the hook 2021 will automatically engage with the fixing column 201 to achieve locking. In this way, the connecting parts 3 arranged inside the shell parts can dock with each other to achieve data and current transmission. Figure 5As shown, when the first shell 101 and the second shell 102 need to be separated, the separation handles 2024 located on both sides of the first shell 101 are pulled, and the hooks 2021 are separated from the fixing column 201, and the first shell 101 and the second shell 102 are also separated. Then, the separation handles 2024 are released, and the hooks 2021 automatically reset under the force of the spring 204, which is convenient for the next docking. Figure 4 and Figure 5 In the figure, the black arrow indicates the moving direction of the shell body and the separation handle 2024.

[0051] The common heavy-duty connector with automatic fastening function realizes automatic locking during docking through the cooperation of the shell part and the locking part. At the same time, no separation tool is required for separation, and separation can be achieved by simply pulling, which reduces labor costs and is convenient and quick to install and disassemble.
