Description

Technical Field

[0001] This utility model relates to the field of electronic connection technology, specifically a connector with a locking structure. Background Technology

[0002] Connectors are widely used in electronics, fluid transmission, and other fields, and their connection stability and protection performance directly affect the reliability of equipment operation. Most existing connectors use a single thread or snap-fit ​​locking structure, which is prone to loosening, axial movement, or even accidental disconnection under complex operating conditions such as vibration and impact, making it difficult to guarantee long-term stable connections. Furthermore, the locking structure and reset function of most products are independent, lacking coordinated design, resulting in untimely reset response, further reducing connection reliability.

[0003] A search revealed existing technology (application number: CN202322699526.0), which describes "a radio frequency coaxial connector with a locking structure." This utility model includes a first connector, a first spring, a latching rod, and a second spring. A slider is provided on the outer side of the first connector, and a groove is connected to the outer side of the slider.

[0004] However, while the existing technology avoids water stains and direct contact with air, and can fix the first and second connectors at the front end of the shell, making it convenient and quick to use, and also prevents the connection between the first and second connectors from loosening, and has a first spring on the underside of the shell so that the shell can automatically reset after being opened, it still has some shortcomings: the device has too many springs, which puts too high demands on manufacturing process and cost, and is not suitable for large-scale general use. Moreover, the device has too many small parts, making disassembly and replacement time-consuming and laborious. Utility Model Content

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a connector with a locking structure, comprising a sub-shell with a groove inside and a sub-post through one side, the sub-post being threadedly connected to the sub-shell; a sub-ring welded to one side of the sub-post; and a mother ring through the outer wall of the sub-ring, on which a reset component is provided.

[0007] As a further description of the above technical solution:

[0008] The reset assembly includes: a torsion spring, one side of which is fixed inside the mother ring; and a mother post, which is rotatably disposed inside the mother ring and one side is fixedly connected to the torsion spring.

[0009] As a further description of the above technical solution:

[0010] The reset assembly further includes a female housing, which is disposed through one side of the female post and threadedly connected to the female post.

[0011] As a further description of the above technical solution:

[0012] The outer wall of the sub-ring has irregular protrusions, and the inner wall of the mother ring also has irregular protrusions.

[0013] As a further description of the above technical solution:

[0014] A sealing ring is provided at the connection between the mother ring and the daughter ring.

[0015] As a further description of the above technical solution:

[0016] A through groove is provided between the mother shell and the daughter shell, and a through groove is also provided between the daughter column and the mother column.

[0017] As a further description of the above technical solution:

[0018] Both the outer side of the child ring and the mother post are provided with protruding circular rings.

[0019] This utility model has the following beneficial effects:

[0020] 1. By using the irregular protrusions of the female and male rings, the protruding circular ring for limiting and the threaded connection structure, combined with the torsion spring driven reset mechanism, a fast locking and limiting system is formed, which improves the stability of the connector connection, ensures the reliability of the connection, and also has the advantages of simple structure and easy use.

[0021] 2. Through the sealing ring design at the connection between the mother ring and the daughter ring, combined with the coaxial through groove structure, stable transmission of cables or fluids is achieved while blocking the intrusion of external media, taking into account both transmission functionality and sealing protection, and adapting to the needs of multiple application scenarios.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The utility model will be further described in detail below with reference to the accompanying drawings.

[0031] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] Example 1:

[0033] like Figures 1 to 6As shown, this embodiment provides a connector with a locking structure, including: a sub-shell 1, which has a groove inside and a sub-post 21 that runs through one side, and the sub-post 21 is threadedly connected to the sub-shell 1; a sub-ring 2, which is welded to one side of the sub-post 21; and a female ring 3, which runs through the outer wall of the sub-ring 2 and has a reset component on the female ring 3.

[0034] In this embodiment, the reset component and the locking component constitute a connector with a locking structure according to this application.

[0035] Understandable Figure 1 This illustration only schematically shows some components of a connector with a locking mechanism; the actual shape, size, location, and construction of these components are not subject to change. Figure 1 Due to limitations, a connector with a locking structure can also include, compared to... Figure 1 More or fewer parts.

[0036] Furthermore, in this embodiment, the threaded fixing of the sub-pillar 21 and the sub-shell 1, the synchronous operation of the sub-ring 2 and the sub-pillar 21, and the mother ring 3 achieves the reset of the relative sub-ring 2 through the reset component, thus forming the basic framework of the connector and realizing the initial assembly of the sub-component and the mother component.

[0037] Specifically, the reset assembly includes: a torsion spring 32, one side of which is fixed inside the mother ring 3; and a mother post 31, which is rotatably disposed inside the mother ring 3 and one side is fixedly connected to the torsion spring 32.

[0038] In this embodiment, the left end of the torsion spring 32 is fixed in the left groove inside the mother ring 3, and the right end is fixedly connected to the mother post 31. When the mother post 31 rotates, it drives the torsion spring 32 to deform. When the torsion spring 32 resets, it drives the mother post 31 to rotate in the opposite direction, thereby realizing the automatic reset of the mother post 31 and providing reset power for the locking structure.

[0039] Specifically, the reset assembly also includes a mother shell 4, which is disposed through one side of the mother post 31 and threadedly connected to the mother post 31.

[0040] As a preferred implementation, the mother shell 4 is fixed to the mother column 31 by threads to form a complete structure of the mother component, which strengthens the integrity of the mother component and provides an installation basis for subsequent sealing and through-slot structures.

[0041] Example 2:

[0042] Based on Example 1, in order to further improve locking stability, a locking device is arranged inside the sub-ring 2;

[0043] Specifically, the outer wall of the sub-ring 2 is provided with irregular protrusions, and the inner wall of the mother ring 3 is also provided with irregular protrusions.

[0044] In this embodiment, four irregular protrusions are evenly distributed along the circumference on the outer wall of the sub-ring 2, and four irregular protrusions are evenly distributed on the inner wall of the mother ring 3. The protrusions are adapted to the positions of the sub-ring 2. When the ring 2 and the mother ring 3 rotate relative to each other, the protrusions engage or disengage to lock or unlock, thereby enhancing the connection stability between the sub-ring 2 and the mother ring 3 and preventing accidental detachment.

[0045] Specifically, a sealing ring is provided at the connection between the mother ring 3 and the daughter ring 2.

[0046] With this configuration, the sealing ring is fitted into the gap between the female ring 3 and the female ring 2, which can fill the gap between the two to block the entry of external media and improve the sealing performance of the connector to prevent liquid or gas from entering.

[0047] Example 3:

[0048] Based on Example 2, in order to connect the sealing device and assist in disassembly, a connecting channel is arranged inside the sub-shell 1;

[0049] Specifically, a through groove is provided between the mother shell 4 and the daughter shell 1, and a through groove is also provided between the daughter column 21 and the mother column 31.

[0050] Among them, the through slot between the mother shell 4 and the daughter shell 1 is cylindrical and has one coaxial opening. The through slot between the daughter post 21 and the mother post 31 is cylindrical and has one coaxial opening, passing through the axis of both. The through slot provides a through channel for the circuit to meet the signal transmission requirements of the connector.

[0051] Specifically, both the outer side of the sub-ring 2 and the mother post 31 are provided with protruding circular rings.

[0052] In this embodiment, one protruding ring on the outer side of the sub-ring 2 is coaxially arranged on the outer side of the central mother column 31, and another protruding ring on the outer side is coaxially arranged on its left end. The shape of the multiple rings on its surface can increase friction during disassembly, making it convenient for personnel to disassemble.

[0053] In actual use, the two sets of wires to be connected are inserted through the sub-shell 1 and the mother shell 4. Then, the sub-post 21 and the mother post 31 are screwed into the sub-shell 1 and the mother shell 4 through their own threads. Since there is a through groove between the mother post 31 and the sub-post 21, the wires pass through the sub-post 21 and the mother post 31 and can be connected in the sub-ring 2 and the mother ring 3. At this time, the sub-ring 2 is inserted into the mother ring 3. The protrusion on the surface of the sub-ring 2 engages with the concave surface inside the mother ring 3, and the mother ring 3 rotates under the guidance of the two sets of protrusions, compressing the torsion spring 32 on one side of the mother ring 3. When the sub-ring 2 is fully engaged in the mother ring 3, the torsion spring 32 returns to its original position, causing the mother ring 3 to rotate. At this time, the protrusions inside the mother ring 3 and the sub-ring 2 engage, and the sub-ring 2 and the mother ring 3 are locked, achieving sealing and connection at the wire connection point.

[0054] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
