Description

Technical Field

[0001] This utility model relates to the field of electrical connector technology, specifically a connector with a rotating docking function. Background Technology

[0002] In fields such as industrial automation, rail transportation, new energy vehicles, and high-end equipment, electrical connectors are key components for realizing power and signal transmission between devices. The reliability, safety, and operational efficiency of their connections are of paramount importance. Traditional electrical connection methods mostly adopt direct-insertion or threaded locking structures. While direct-insertion connections are simple to operate, they have poor vibration resistance and are prone to loosening or even detachment due to vibrations during equipment operation. Threaded locking connections, on the other hand, provide a secure connection, but are cumbersome and time-consuming to operate, making it difficult to meet the needs of high-frequency insertion and removal and rapid maintenance.

[0003] However, existing rotary docking connectors still have significant drawbacks. On the one hand, in most structures, the rotary locking mechanism is independent of the insertion action, lacking a mechanical limit or linkage feedback mechanism for proper insertion. This results in rotary locking being completed before the male and female terminals are fully inserted, easily leading to safety hazards such as poor contact, intermittent connection, or even localized overheating and burning. On the other hand, their locking relies heavily on external threads or retaining rings for clamping, lacking an active locking design for the internal electrical connection terminals. Under long-term vibration or impact conditions, fretting wear or loosening of contact can easily occur between the terminals, affecting signal integrity and power supply stability.

[0031] Example 1:

[0032] like Figures 1 to 5 As shown, this embodiment provides a connector with a rotating docking function, comprising: a first cable 1, with a second cable 11 disposed at one end; a male connector assembly 2, disposed at the end where the second cable 11 connects to the first cable 1, including a male connector sleeve 22 disposed on the outer wall of one end of the second cable 11; a female connector assembly 3, disposed at the end where the first cable 1 connects to the second cable 11, including a female connector sleeve 32 disposed on the outer wall of one end of the first cable 1; and a connecting module 4, disposed inside the male connector sleeve 22 and the female connector sleeve 32, including a rotating assembly 41 disposed inside the female connector sleeve 32 and the male connector sleeve 22.

[0033] In this embodiment, the rotating component 41 and the locking component 42 constitute a connector with a rotating docking function according to this application.

[0034] Furthermore, in this embodiment, the male connector assembly 2 includes a male connector sleeve 22 for connecting the second cable 11. The female connector assembly 3 includes a female connector sleeve 32 for connecting the first cable 1. The connection module 4 includes a rotating assembly 41 for achieving a rotating docking function. The first cable 1 and the second cable 11 are connected through the male connector assembly 2 and the female connector assembly 3. The connection module 4 achieves rotating docking through the rotating assembly 41, and the locking assembly 42 ensures the stability of the connection. This provides a stable rotating docking function, ensuring the stability and reliability of the cable connection.

[0035] Specifically, two sets of sliding grooves are provided on the outside of the public line connecting sleeve 22.

[0036] In this embodiment, the rotating block 411 slides within the groove, thereby rotating the rotating sleeve 412. This provides a stable rotation function, ensuring the precise rotation of the rotating sleeve 412.

[0037] Specifically, the public wire connector assembly 2 includes a public wire connection terminal 21, which is disposed on one side of the second cable 11 and located inside the public wire connection sleeve 22.

[0038] In a preferred embodiment, the male connection terminal 21 is connected to the female connection terminal 31 via a rotating sleeve 412. This provides a stable connection, ensuring the transmission of signals or power.

[0039] Specifically, the bus connector assembly 3 includes a bus connection terminal 31, which is disposed on one side of the first cable 1 and located inside the bus connection sleeve 32, and the bus connection terminal 31 is inserted into the male connection sleeve 22.

[0040] In this embodiment, the busbar connection terminal 31 is inserted into the male line connection sleeve 22, and the connection stability is ensured by the locking component 42. This provides a stable connection function, ensuring the transmission of signals or power.

[0041] Example 2:

[0042] Based on Embodiment 1, in order to provide stable rotation and locking functions, a rotating component 41 is provided inside the busbar connecting sleeve 32 and the male connecting sleeve 22.

[0043] Specifically, the rotating assembly 41 includes: two sets of rotating blocks 411, which rotate 90 degrees within the sliding groove on the outer wall of the male connection sleeve 22; a rotating sleeve 412, which is rotatably disposed inside the male connection sleeve 22 and located on the outer wall of the male connection terminal 21, with its two outer walls fixedly connected to the rotating blocks 411; a sliding ring 413, which slides inside the busbar connection sleeve 32 and abuts against one end of the rotating sleeve 412; two sets of sliding blocks 414, which slide on the outer wall of the busbar connection sleeve 32 and are fixedly connected to the outer wall of the sliding ring 413; a compression spring 415, which is disposed inside the busbar connection sleeve 32 and abuts against the other side of the sliding ring 413; a snap-fit ​​block 416, which is disposed on both sides of the busbar connection sleeve 32 near the rotating sleeve 412; and a snap-fit ​​groove 417, which is formed on both sides of the rotating sleeve 412 near the sliding ring 413, with the snap-fit ​​block 416 inserted into the snap-fit ​​groove 417.

[0044] In this configuration, the rotating block 411 is rectangular and drives the rotating sleeve 412 to rotate. The rotating sleeve 412 is a hollow cylindrical structure. The sliding block 414 is rectangular. The busbar connection terminal 31 is inserted into the male line connection sleeve 22. The rotating sleeve 412 enters the busbar connection sleeve 32, the locking block 416 is pushed, and the sliding ring 413 is pressed against the compression spring 415. The sliding blocks 414 at both ends of the sliding ring 413 slide until the sliding ring 413 slides to the bottom. The user squeezes the two sets of rotating blocks 411 and rotates them 90 degrees. The rotating block 411 drives the rotating sleeve 412 to rotate 90 degrees, and the locking groove 417 coincides with the locking block 416. The compression spring 415 returns to its original position and pushes the sliding ring 413. The sliding ring 413 drives the locking block 416 to slide into the locking groove 417 and lock the rotating sleeve 412. This provides stable rotation and locking functions to ensure the stability of the connection.

[0045] Example 3:

[0046] Based on Embodiment 2, in order to provide a stable locking function, a locking component 42 is provided inside the rotating sleeve 412.

[0047] Specifically, the connection module 4 includes a locking component 42, which is disposed inside the rotating sleeve 412.

[0048] The locking assembly 42 ensures connection stability through the friction convex ball 422 and the locking spring 423. It provides a stable locking function, ensuring connection reliability.

[0049] Specifically, the locking assembly 42 includes: an arc-shaped groove 421, formed on both sides of the inner wall of the rotating sleeve 412; a friction convex ball 422, disposed on both sides inside the public line connection terminal 21, with one end contacting the arc-shaped groove 421; a locking spring 423, disposed on both sides inside the public line connection terminal 21, with one end fixedly connected to the friction convex ball 422; and a locking groove 424, formed on both sides of the outer wall of the busbar connection terminal 31, with the other end of the locking spring 423 being engaged in the locking groove 424.

[0050] In this embodiment, the arc-shaped groove 421 is used for the sliding of the friction protrusion 422. When the rotating sleeve 412 rotates, the friction protrusion 422 slides within the arc-shaped groove 421 until it disengages. The friction protrusion 422 is then pressed by the inner wall of the rotating sleeve 412 towards the locking spring 423. The locking spring 423 deforms and protrudes towards the inner wall of the common line connection terminal 21, engaging within the locking groove 424. This provides a stable locking function, ensuring the stability of the connection.

[0051] In actual use, the user first inserts the end of the first cable 1 with the busbar connection terminal 31 into the end of the second cable 11 with the male connection terminal 21. The rotating sleeve 412 enters the busbar connection sleeve 32 and continues to enter after contacting the locking block 416. The locking block 416 is pushed, which causes the sliding ring 413 to press against the compression spring 415. The sliding blocks 414 at both ends of the sliding ring 413 slide until the sliding ring 413 slides to the bottom. At this time, the user squeezes the two sets of rotating blocks 411 and rotates them 90 degrees. The rotating blocks 411 drive the sliding ring 413 to move towards the compression spring 415. The rotating sleeve 412 rotates 90 degrees and the locking groove 417 coincides with the locking block 416. The compression spring 415 returns to its original position and pushes the sliding ring 413. The sliding ring 413 drives the locking block 416 to slide into the locking groove 417 and lock the rotating sleeve 412. As the rotating sleeve 412 rotates, the arc groove 421 rotates. The friction convex ball 422 slides in the arc groove 421 until it disengages. The friction convex ball 422 is pressed by the inner wall of the rotating sleeve 412 and moves towards the locking spring 423. The locking spring 423 deforms and protrudes into the inner wall of the public line connection terminal 21, locking in the locking groove 424.

[0052] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
