Description

Technical Field

[0001] The utility model relates to the technical field of connectors, and more specifically, to a connecting mechanism for a circular connector. Background Art

[0002] Circular connectors are commonly used for signal transmission and exhibit excellent performance especially in the field of low-voltage signal transmission. Therefore, they play an indispensable role in high-precision and high-requirement application scenarios such as automotive electronic control systems and military aviation. Through precise contact interface and housing design, the connectors ensure the integrity of signal transmission and environmental adaptability, meeting the needs of complex and changeable industrial environments.

[0003] However, with the continuous progress of technology and the continuous expansion of application scenarios, the connection methods of traditional circular connectors gradually show their limitations. Taking the two most common connection methods as examples: Although the threaded connection can provide a certain fastening force, in the face of strong vibration or long-term use environments, its anti-vibration performance is often insufficient. Coupled with the erosion of environmental factors such as corrosion and dust accumulation, it is extremely easy to cause the thread to jam, making the disassembly and maintenance of the connector extremely difficult. On the other hand, the push-pull latch, as a more convenient connection method, although simplifies the connection process, due to its complex structure, it not only increases the manufacturing cost but also improves the assembly difficulty.

[0004] The above deficiencies need to be improved. Summary of the Invention

[0005] In order to solve or alleviate the problems of poor maintainability and manufacturing convenience of existing connectors, the utility model provides a connecting mechanism for a circular connector.

[0006] The technical solution of the utility model is as follows:

[0007] A connecting mechanism for a circular connector includes a first connecting sleeve and a second connecting sleeve. One of the first connecting sleeve and the second connecting sleeve is arranged on the male head, and the other is arranged on the female seat. A limiting slider is arranged on the first connecting sleeve, and a limiting chute for the limiting slider to slide is arranged on the second connecting sleeve. An elastic limiting member is also arranged on the second connecting sleeve. The elastic limiting member restricts the sliding of the limiting slider in the limiting chute at the first position, and releases the limiting slider to freely slide in the limiting chute at the second position.

[0008] Further, the limiting chute includes a first limiting portion and a second limiting portion. The first limiting portion extends axially from the end of the second connecting sleeve, and the second limiting portion extends circumferentially from the second end of the first limiting portion.

[0009] Further, the elastic limiting member includes a locking portion, a locking hole penetrating through the second limiting portion is provided on the second connecting sleeve. When the elastic limiting member is in the first position, the locking portion is inserted into the locking hole. When the elastic limiting member is in the second position, the locking portion is away from the locking hole.

[0010] Further, a first sliding surface is provided on one side of the limiting slider, and a first limiting surface is provided on the other side. A second sliding surface slidably engaged with the first sliding surface is provided on the elastic limiting member, and a second limiting surface abutted against the first limiting surface is provided on the other side.

[0011] Further, the elastic limiting member includes a connecting portion, and the connecting portion is detachably connected to the second connecting sleeve.

[0012] Further, the connecting portion includes a clamping groove, a connecting column engaged with the clamping groove is provided on the second connecting sleeve, a blocking block is provided at the top of the connecting column, and the opening size of the clamping groove is larger than the diameter of the connecting column.

[0013] Further, the elastic limiting member includes a deforming portion, the deforming portion connects the locking portion and the connecting portion, and the deforming portion is made of an elastic material.

[0014] Further, the second connecting sleeve is rotatably connected to the male head or the female seat.

[0015] Further, a first limiting ring is provided on the second connecting sleeve, a second limiting ring abutted against the first side of the first limiting ring is provided on the male head or the female seat, a limiting sleeve abutted against the second side of the first limiting ring is sleeved on the male head or the female seat, a buckle is provided on the limiting sleeve, and a ring groove engaged with the buckle is provided on the male head or the female seat.

[0016] Further, a guiding slideway is axially provided on the first connecting sleeve, and a guiding slide bar slidably engaged with the guiding slideway is provided on the male head or the female seat.

[0017] For the utility model according to the above solution, its beneficial effects are as follows. The utility model makes the male head and the female seat firmly connected through the cooperation of the limiting slider and the limiting chute, and limits the position of the limiting slider in the limiting chute through the elastic limiting member. Compared with the traditional threaded connection, sliding does not rely on the tight meshing of the threads to maintain the connection stability, so it shows better reliability and durability in the face of a long-term vibration environment. Compared with complex structures such as push-pull latches, the connecting mechanism of this design has fewer components and a compact structure, simplifies the assembly process, reduces the requirement for assembly accuracy, helps to improve production efficiency, and reduces the overall cost by reducing the number of components and the processing complexity.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0027] As Figure 1 shown, in an embodiment of the present utility model, a connection mechanism for a circular connector includes a first connection sleeve 1 and a second connection sleeve 2. The first connection sleeve 1 is arranged on a female seat 6, and one of the second connection sleeves 2 is arranged on a male head 5. A limit slide block 101 is arranged on the first connection sleeve 1, and a limit slide groove 201 for the limit slide block 101 to slide is arranged on the second connection sleeve 2. An elastic limit member 3 is further arranged on the second connection sleeve 2. The elastic limit member 3 restricts the limit slide block 101 from sliding in the limit slide groove 201 at a first position, and releases the limit slide block 101 to freely slide in the limit slide groove 201 at a second position.

[0028] In this embodiment, through the cooperation of the limit slide block 101 and the limit slide groove 201, and by using the elastic limit member 3 to restrict the position of the limit slide block 101 in the limit slide groove 201, the male head 5 and the female seat 6 are firmly connected. When separation is required, the elastic limit member 3 is toggled to the second position. At this time, the limit slide block 101 can freely slide in the limit slide groove 201, enabling the male head 5 and the female seat 6 to be separated. Compared with traditional threaded connections, sliding does not rely on the tight meshing of threads to maintain connection stability, so it shows better reliability and durability in the face of long-term vibration environments. In addition, when needed, users can easily release the limit slide block 101 from the limit slide groove 201, thereby achieving the quick separation of the connector, avoiding the problem of difficult disassembly caused by corrosion or dust accumulation in threaded connections, and reducing the maintenance cost. At the same time, since connection and separation operations can be completed without using special tools, the user experience is improved. Compared with complex structures such as push-pull latches, the connection mechanism of this design has fewer components and a compact structure, simplifies the assembly process, reduces the requirements for assembly accuracy, helps to improve production efficiency, and reduces the overall cost by reducing the number of components and the processing complexity.

[0029] In actual application, the first connecting sleeve 1 can be arranged on the male head 5, and the second connecting sleeve 2 can be arranged on the female socket 6. In addition, the first connecting sleeve 1 and the second connecting sleeve 2 can be integrally formed with the male head 5 and the female socket 6 respectively.

[0030] As Figure 2 shown, in a preferred example, the limiting chute 201 includes a first limiting portion 202 and a second limiting portion 203. The first limiting portion 202 extends axially from the end of the second connecting sleeve 2, and the second limiting portion 203 extends circumferentially from the second end of the first limiting portion 202.

[0031] The elastic limiting member 3 includes a locking portion 301. A locking hole 204 penetrating through the second limiting portion 203 is arranged on the second connecting sleeve 2. When the elastic limiting member 3 is in the first position, the locking portion 301 is inserted into the locking hole 204. When the elastic limiting member 3 is in the second position, the locking portion 301 is away from the locking hole 204.

[0032] One side of the limiting slider 101 is provided with a first sliding surface 102, and the other side is provided with a first limiting surface 103. The elastic limiting member 3 is provided with a second sliding surface 302 that slidably cooperates with the first sliding surface 102, and the other side is provided with a second limiting surface 303 that abuts against the first limiting surface 103.

[0033] When the first connecting sleeve 1 and the second connecting sleeve 2 are connected:

[0034] First, align the limiting slider 101 with the first limiting portion 202 of the limiting chute 201, and then insert the first connecting sleeve 1 into the second connecting sleeve 2 so that the limiting slider 101 enters the first limiting portion 202 of the limiting chute 201. As the first connecting sleeve 1 is inserted, it reaches the second limiting portion 203 until the first connecting sleeve 1 and the second connecting sleeve 2 rotate relative to each other, that is, the limiting slider 101 slides in the second limiting portion 203. During this process, the locking portion 301 of the elastic limiting member 3 remains inserted into the locking hole 204 and is in the first position. As the further sliding occurs, the first sliding surface 102 gradually contacts and slides past the locking portion 301. The first sliding surface 102 and the second sliding surface 302 enable the limiting slider 101 to smoothly slide past the locking portion 301. At this time, the first limiting slider 101 slides to the end of the second limiting portion 203, and at the same time, the second limiting surface 303 contacts the first limiting surface 103, that is, it limits the front and back of the limiting slider 101, so that it is stably in the second limiting portion 203 and is in the locked state.

[0035] When the first connecting sleeve 1 and the second connecting sleeve 2 are separated:

[0036] First, the elastic limiting member 3 is moved from the first position to the second position, the locking portion 301 is withdrawn from the locking hole 204, and the limiting slider 101 resumes the free sliding state in the limiting slide groove 201. At this time, the user can pull the first connecting sleeve 1 out of the second connecting sleeve 2 to complete the separation of the connectors.

[0037] In this embodiment, the connector can be quickly connected and disconnected through simple operations without the use of special tools, which improves the convenience of operation. The structural design is reasonable, which can resist the influence of environmental factors such as corrosion and dust accumulation on the connection performance, and improve the environmental adaptability of the connector. The small number of parts and compact structure help save space and reduce the overall weight, and are suitable for application scenarios with strict requirements on space and weight.

[0038] like Figure 2 As shown, in a preferred example, the elastic limiting member 3 includes a connecting portion 304 , and the connecting portion 304 is detachably connected to the second connecting sleeve 2 .

[0039] The connecting portion 304 includes a slot, and a connecting column 205 engaged with the slot is provided on the second connecting sleeve 2 . A stopper 206 is provided on the top of the connecting column 205 . The opening size of the slot is larger than the diameter of the connecting column 205 .

[0040] In this embodiment, the opening size of the slot is larger than the diameter of the connecting column 205, so that the connecting column 205 can be easily inserted into the slot and is restricted from coming out by the stopper 206, thereby simplifying the installation process. At the same time, the locking portion 301 is engaged in the locking hole 204, so that the slot and the connecting column 205 remain in a clamped state. When disassembly is required, the locking portion 301 is pulled out of the locking hole 204, and then the elastic limiter 3 is pulled to separate the slot from the connecting column 205, which is convenient for disassembly. Due to the detachable design, when any component in the elastic limiter 3 or the second connecting sleeve 2 is damaged, it can be replaced separately without replacing the entire assembly, which reduces the maintenance cost and difficulty. Quick installation and disassembly help shorten the assembly time on the production line and improve production efficiency.

[0041] In practical applications, the elastic limiting member 3 can be fixed to the second connecting sleeve 2 by fasteners such as screws.

[0042] like Figure 2 As shown, in a preferred embodiment, the elastic limiting member 3 includes a deformation portion 305, the deformation portion 305 connects the locking portion 301 and the connecting portion 304, and the deformation portion 305 is made of elastic material. The elastic limiting member 3 is integrally formed and made of steel sheet or plastic.

[0043] In this embodiment, the integrally formed elastic limiting member 3 has a compact structure and is stable and firm. The elastic characteristics of the deformation part 305 enable the limiting member to deform when subjected to an external force, facilitating the change of the working position and thus facilitating use.

[0044] As Figure 2 shown, in a preferred example, the second connecting sleeve 2 is rotatably connected to the male head 5 or the female seat 6.

[0045] A first limiting ring 207 is provided on the second connecting sleeve 2, a second limiting ring 501 abutted against the first side of the first limiting ring 207 is provided on the male head 5 or the female seat 6, a limiting sleeve 4 abutted against the second side of the first limiting ring 207 is sleeved on the male head 5 or the female seat 6, a buckle 401 is provided on the limiting sleeve 4, and a ring groove 502 engaged with the buckle 401 is provided on the male head 5 or the female seat 6.

[0046] Anti-slip textures are provided on the outer side of the second connecting sleeve 2.

[0047] The second connecting sleeve 2 is rotatably connected to the male head 5, facilitating the sliding of the limiting slider 101 in the second limiting part 203 and facilitating connection and separation. By providing the first limiting ring 207 and the limiting sleeve 4 to limit the second limiting ring 501, the second connecting sleeve 2 is limited, preventing the second connecting sleeve 2 from falling off the male head 5. On the one hand, it ensures that the second connecting sleeve 2 can rotate freely, and on the other hand, it improves the structural stability. The buckle 401 on the limiting sleeve 4 is engaged with the ring groove 502 on the male head 5, facilitating the installation of the second connecting sleeve 2 and the limiting sleeve 4 and facilitating the assembly of the connector. The anti-slip textures provided on the outer side of the second connecting sleeve 2 increase the surface roughness, improve the holding feeling and stability during user operation, and facilitate user operation.

[0048] As Figure 2 shown, in a preferred example, a guiding slideway 104 is axially provided on the first connecting sleeve 1, and a guiding slide bar 503 matched with the guiding slideway 104 is provided on the male head 5.

[0049] In this embodiment, the cooperation between the guiding slide bar 503 and the guiding slideway 104 provides precise guidance for the connection process of the male head 5 and the female seat 6, ensuring that the first connecting sleeve 1 can be smoothly and accurately inserted into the male head 5 along a predetermined trajectory, preventing connection failure or damage caused by deviation or misalignment.

[0050] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
