Description

Technical Field

[0001] This utility model relates to the field of electrical connection technology, and in particular to an M12-Y type connector. Background Technology

[0002] Currently, M12 connectors are widely used in industrial automation, sensor technology, and electrical equipment. Due to their compact size, robustness, and waterproof / dustproof properties, they are widely used in various demanding environments. Y-type connectors, as a variant of the M12 connector, typically have three ports, enabling parallel connections of multiple devices. They are suitable for scenarios involving multi-device transmission and signal distribution. Their structural design allows for simple device connections, avoiding the complex layout and wiring problems associated with multiple individual connectors.

[0003] For the aforementioned Y-connector applications, existing technologies utilize ball joints or similar rotating structures to provide a certain degree of angle adjustment, allowing the connector to adapt to different installation spaces. This structure provides a degree of rotational freedom, making the connector more flexible in different orientations. Regarding the connection port, the connector uses a simple socket and plug mating to ensure the transmission of electrical signals.

[0004] However, existing Y-type connectors have certain shortcomings. First, while existing connectors offer rotation functionality, they typically lack an effective locking mechanism to ensure the stability of the rotation angle after installation. Without a reliable locking device, angular misalignment is prone to occur after installation, especially under environmental vibration or prolonged use, potentially leading to loosening or instability. Second, traditional Y-type connectors lack anti-mismating designs, failing to effectively prevent incorrect connections in high-pressure or rapid installation environments. Such mismating not only affects normal equipment operation but also increases the complexity of debugging and maintenance. Furthermore, existing socket and plug designs lack sufficient locking mechanisms, failing to provide a stable and reliable connection, making them susceptible to loosening or signal loss in high-vibration or high-pressure environments.

[0005] To address the above issues, an M12-Y type connector is proposed. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides an M12-Y type connector, which aims to solve the problems of poor spatial flexibility and slow plug connection speed of the existing M12-Y type connector.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: an M12-Y type connector, comprising a main body housing, a ball joint rotatably connected to one side of the main body housing, two connection ports symmetrically arranged on the other side of the main body housing, an external threaded joint fixedly connected to the side of the ball joint away from the main body housing, a rubber sealing ring installed at the port of the external threaded joint, a locking nut threadedly connected to the outer side of the external threaded joint, a socket provided inside the connection port, a limit assembly provided inside the main body housing, the limit assembly comprising a fixing rod slidably connected inside the main body housing, an inner groove opened inside the main body housing, a limit plate fixedly connected to the middle of the fixing rod, the limit plate slidably connected inside the inner groove, and a spring sleeved on the outer side of the fixing rod.

[0008] As a further description of the above technical solution:

[0009] A handle is fixedly connected to the top of the fixing rod.

[0010] As a further description of the above technical solution:

[0011] The spring is located inside the inner groove, with its top fixedly connected to the inner top wall of the inner groove and its bottom fixedly connected to the top of the limiting plate.

[0012] As a further description of the above technical solution:

[0013] The spherical joint located inside the main housing has multiple limiting grooves, and the bottom of the fixing rod is inserted into one of the limiting grooves.

[0014] As a further description of the above technical solution:

[0015] A protruding key is fixedly connected to the inner wall of the connection port.

[0016] As a further description of the above technical solution:

[0017] Two hooks are symmetrically arranged at the port of the connection.

[0018] As a further description of the above technical solution:

[0019] An external plug is inserted into the inside of the connection port. The external plug has multiple pins inside, and these pins are inserted into the inside of the socket.

[0020] As a further description of the above technical solution:

[0021] The external connector has a groove on its outer side, the key slides inside the groove, and the external connector has a slot on its outer side, the bent part of the hook engages inside the slot.

[0022] This utility model has the following beneficial effects:

[0023] 1. This utility model introduces a ball joint connection device and a rotation locking mechanism, allowing the connector to rotate freely after installation and adjust the installation angle to adapt to different space requirements. This effectively improves the flexibility and adaptability of the connector, especially in narrow or space-constrained environments, enabling users to easily adjust the direction, optimize the installation layout and operating space of the equipment, while ensuring the stability of the connection and the reliability of long-term use.

[0024] 2. In this invention, by designing protruding keys inside the two connection ports of the connector branch, it is ensured that the external plug can only be inserted in the correct direction, preventing the possibility of misinsertion. This not only avoids the risk of poor contact or equipment failure, but also improves the accuracy and safety of installation. Especially in environments requiring rapid installation or with poor visibility, the anti-reverse insertion design significantly improves operational efficiency. Furthermore, the hooks provided at the ports effectively enhance the strength of the connector connection. Attached Figure Description

The fixing rod 7 is slidably connected inside the main housing 5, and its bottom inserts into one of the multiple limiting slots provided in the ball joint 4, ensuring that the ball joint 4 is limited to a preset angle during rotation. The fixing rod 7 is also connected to a limiting plate 9, which slides in an inner groove inside the main housing 5. A spring 8 on the outside of the fixing rod 7 provides sufficient rebound force to ensure that the connector is firmly fixed after angle adjustment. One end of the spring 8 is fixedly connected to the top wall of the inner groove, and the other end is fixedly connected to the top of the limiting plate 9, ensuring that the limiting plate 9 can slide stably during operation. Through the above design, the M12-Y type connector of this embodiment ensures connection reliability while having strong flexibility, adapting to various installation requirements, effectively preventing mis-insertion, and improving operational safety and installation efficiency.

[0034] Working Principle: The main body housing 5 of the connector is connected to the external threaded connector 1 via a ball joint 4. The ball joint 4 allows the main body housing 5 to be rotated and adjusted after installation. Two connection ports 6 of the connector are symmetrically arranged on one side of the main body housing 5, each port having a socket 11 inside. The socket 11 is electrically connected to multiple pins 17 within the external plug 14. The external plug 14 engages with the protruding key 12 within the connection port 6 via a sliding groove 15, ensuring that the plug can only be inserted in the correct direction. The slot 16 on the outside of the external plug 14 engages with the hook 13 on the connection port 6, locking the plug to the connection port 6. A limiting assembly is provided inside the main body housing 5. A fixing rod 7 is slidably connected in the inner groove within the main body housing 5 and connected to a limiting plate 9, which slides along the inner groove.
