Abstract
Description
Technical Field
[0001] This invention relates to the field of connector technology, and more specifically to a flexible structure connector. Background Technology
[0002] Cable connectors, through their precise mechanical design, can tightly and securely connect cables to various devices or other cables, creating a complete and unobstructed electrical path to ensure the smooth flow of current or signals. In the field of signal transmission, high-quality cable connectors play a crucial role. Using advanced technology and materials, they minimize signal attenuation during transmission, reduce distortion, and resist external interference, thereby ensuring signal integrity and accuracy. This provides strong support for the stable operation of various electronic devices and the precise transmission of data.
[0003] Within the current technological framework, the dustproof performance of cable connectors has received considerable attention. To improve the dustproof capability of connectors, dustproof structures are typically incorporated into the connector ends. Currently, the most common dustproof structure installation methods are snap-fit and threaded connections. However, both of these installation methods are essentially rigid connection modes, exhibiting a significant drawback—the lack of effective anti-detachment mechanisms. In actual use, due to external environmental factors (such as vibration and impact) or human operation, the dustproof structure can easily detach from the connector body. Once the dustproof structure falls off, the connector's dustproof effect will be greatly reduced, allowing dust, impurities, and other foreign objects to enter the connector's interior, thereby affecting its electrical performance, shortening its lifespan, and potentially threatening the stable operation of the entire electronic system. Summary of the Invention
[0004] To solve the above technical problems, the present invention provides an elastic structure connector that locks the dust cap to the outer shell through an elastic mechanical locking method. The structure is simple and easy to use.
[0005] The present invention adopts the following technical solution: A flexible connector includes a dust cap, a housing, a spindle, a jaw, and a tail sleeve; the jaw is disposed at a first end of the spindle and the tail sleeve is sleeved on the first end of the spindle; the dust cap is sleeved on the second end of the spindle, and the housing is sleeved on the outside of the dust cap; the inner wall of the housing is provided with a limiting groove, and the outer side of the dust cap is provided with a limiting block that can move from a first position A to a second position B of the limiting groove; the housing is also provided with a spring that abuts against the housing to prevent relative movement between the dust cap and the housing.
[0006] Preferably, the limiting groove is an L-shaped groove, and the limiting block of the dust cap can enter from the first position A at the opening of the L-shaped groove and move relative to the L-shaped groove to the third position C at the bottom of the L-shaped groove and the second position B at the end of the L-shaped groove.
[0007] Preferably, an anti-detachment groove is provided above the second position B.
[0008] Preferably, the outer side of the outer shell is provided with a receiving groove, and the receiving groove is provided with a first limiting protrusion and a second limiting protrusion. The first limiting protrusion and the inner wall of the receiving groove form a first limiting groove, and the first limiting protrusion and the second limiting protrusion form a second limiting groove.
[0009] Preferably, the spring includes a limiting section and an elastic section. The limiting section includes a first limiting section located in a first limiting groove and a second limiting section partially located in a second limiting groove, and the second limiting section has at least a partially bendable free section. The elastic section extends out of the receiving groove and abuts against the dust cap.
[0010] Preferably, when the limiting block moves from the first position A to the third position C, the outer edge protrusion of the dust cap squeezes the elastic segment and causes the elastic segment and the free segment of the second limiting segment to bend downward; when the limiting block moves from the third position C to the second position B, the outer edge protrusion rotates relative to the elastic segment and always squeezes the elastic segment; when the limiting block moves to the second position B, the spring lifts the dust cap so that the limiting block enters the anti-detachment groove.
[0011] Preferably, a spring is provided between the housing and the main shaft, and the housing can rotate relative to the main shaft to compress the spring, thereby causing the spring to be in a compressed state.
[0012] Preferably, the spindle is provided with a slot, the dust cap is provided with a insert that mates with the slot, and the limiting block is located on the surface of the insert. Preferably, when the outer shell is rotated to compress the spring, the inlet of the limiting groove coincides with the slot, and the dust cap is installed on the outer shell. When the limiting block moves from the first position A to the third position C, the spring resets and drives the outer shell to rotate in the opposite direction through elastic force, causing the limiting block to move from the third position C to the second position B.
[0013] Preferably, when the limiting block moves from the third position C to the second position B, one end of the spring abuts against the outer shell and the other end abuts against the main shaft, causing the limiting block and the limiting groove to be in abutting state.
[0014] Preferably, an anti-rotation sleeve is provided between the outer shell and the tail sleeve, the outer shell is provided with a first limiting tooth, and the anti-rotation sleeve is provided with a second limiting tooth that meshes with the first limiting tooth.
[0015] Compared with existing technologies, this invention has the following advantages: This invention innovatively develops a flexible structure connector, which consists of key components such as a dust cap, a housing, a main shaft, claws, and a tail sleeve. Its unique feature is that a limiting groove is carefully designed on the inner wall of the housing, while a corresponding limiting block is configured on the outer side of the dust cap. This limiting block has the ability to flexibly move from a first position A to a second position B in the limiting groove. In practical applications, the elastic force of the spring cleverly utilizes the spring force to form a stable and reliable anti-detachment structure between the limiting block and the limiting groove. This flexible mechanical locking method greatly improves the connection stability between the dust cap and the housing, and is not only simple and clear in structure but also convenient and efficient in operation. It effectively avoids the problem of easy detachment of the dustproof structure in traditional rigid connection methods, greatly improving the dustproof performance and overall stability of the connector, providing users with a more reliable and durable connection solution.

[0032] In the figure, there are: dust cap 1, limiting block 1-1, insert 1-2, outer edge protrusion 1-3, outer shell 2, limiting groove 2-1, receiving groove 2-2, first limiting protrusion 2-2-1, second limiting protrusion 2-2-2, first limiting groove 2-2-3, second limiting groove 2-2-4, anti-detachment groove 2-3, push plate 2-4, first limiting tooth 2-5, main shaft 3, slot 3-1, spring receiving groove 3-2, claw 4, tail sleeve 5, spring 6, limiting section 6-1, first limiting section 6-1-1, second limiting section 6-1-2, elastic section 6-2, anti-rotation sleeve 7, and second limiting tooth 7-1. Detailed Implementation
[0033] To facilitate understanding of the technical solution of the present invention, the following detailed description is provided in conjunction with the accompanying drawings and specific embodiments.
[0034] Example 1 like Figure 1-7 As shown, a flexible structure connector includes a dust cap 1, a housing 2, a main shaft 3, a claw 4, and a tail sleeve 5; The claw 4 is disposed at the first end of the spindle 3 and the tail sleeve 5 is disposed at the first end of the spindle 3; the dust cap 1 is disposed outside the second end of the spindle 3 and the outer shell 2 is disposed outside the dust cap 1; the outer shell 2, the spindle 3, the claw 4 and the tail sleeve 5 are connected to form the main structure of the connector, which can prevent scratches from occurring when the ferrule end face is connected to the adapter.
[0035] like Figure 3-4 As shown, the inner wall of the outer shell 2 is provided with a limiting groove 2-1, and the outer side of the dust cap 1 is provided with a limiting block 1-1 that can move from a first position A to a second position B of the limiting groove 2-1. The outer shell 2 is also provided with a spring 6, one end of which abuts against the outer shell 2 to prevent relative movement between the dust cap 1 and the outer shell 2. That is, in this embodiment, by setting the spring 6, after the dust cap 1 is installed on the outer shell 2, the elastic force of the spring 6 prevents the limiting block 1-1 from detaching from the outer shell 2. Through the elastic mechanical locking method, the connection stability between the dust cap 1 and the outer shell 2 is greatly improved.
[0036] The limiting groove 2-1 is an L-shaped groove. The limiting block 1-1 of the dust cap 1 can enter from the first position A at the opening of the L-shaped groove and move relative to the L-shaped groove to the third position C at the bottom of the L-shaped groove and the second position B at the end of the L-shaped groove. Viewed from the direction shown in the figure, the L-shaped groove is divided into a vertical section and a horizontal section. The opening is the upper end of the vertical section, that is, the first position A is the upper end of the vertical section, the third position C is the connection between the vertical section and the horizontal section, and the second position B is the end of the horizontal section.
[0037] To prevent the limiting block 1-1 from sliding out of the horizontal section of the L-shaped groove, an anti-detachment groove 2-3 is provided above the second position B. When the limiting block 1-1 moves to the second position B, the dust cap 1 can be pushed upward by the elastic force of the spring 6, so that the limiting block 1-1 enters the anti-detachment groove 2-3.
[0038] Specifically, such as Figure 5 As shown, the outer side of the outer shell 2 is provided with a receiving groove 2-2, and the receiving groove 2-2 is provided with a first limiting protrusion 2-2-1 and a second limiting protrusion 2-2-2. The first limiting protrusion 2-2-1 and the inner wall of the receiving groove 2-2 form a first limiting groove 2-2-3, and the first limiting protrusion 2-2-1 and the second limiting protrusion 2-2-2 form a second limiting groove 2-2-4.
[0039] like Figure 6-7 As shown, the spring 6 includes a limiting segment 6-1 and an elastic segment 6-2. The limiting segment 6-1 includes a first limiting segment 6-1-1 located in the first limiting groove 2-2-3 and a second limiting segment 6-1-2 partially located in the second limiting groove 2-2-4. The second limiting segment 6-1-2 has at least a partially bendable free segment. The spring 6 has an approximately S-shaped structure, with the lower end being the limiting segment 6-1 and the upper end being the elastic segment 6-2. The limiting segment 6-1 and the elastic segment 6-2 are connected. The end portion of the limiting segment 6-1 is a vertical or approximately vertical first limiting segment 6-1-1 and a nearly vertical second limiting segment 6-1-2, which facilitates the fixation and anti-detachment of the limiting segment 6-1 of the spring 6.
[0040] During the process of the limiting block 1-1 being inserted into the receiving groove 2-2, the elastic segment 6-2 extends out of the receiving groove 2-2 and abuts against the dust cap 1. When the limiting block 1-1 moves from the first position A to the third position C, the outer edge protrusion 1-3 of the dust cap 1 presses against the elastic segment 6-2, causing the elastic segment 6-2 and the free segment of the second limiting segment 6-1-2 to bend downwards; when the limiting block 1-1 moves from the third position C to the second position B, the outer edge protrusion 1-3 rotates relative to the elastic segment 6-2 and always presses against the elastic segment 6-2; when the limiting block 1-1 moves to the second position B, the spring 6 lifts the dust cap 1, causing the limiting block 1-1 to enter the anti-detachment groove 2-3.
[0041] In use, first place the dust cap 1 on the outer shell 2, aligning the limiting block 1-1 with the entrance of the receiving groove 2-2. Then, move the dust cap 1 downwards so that the limiting block 1-1 enters the receiving groove 2-2, compressing the spring 6. Next, rotate the outer shell 2, moving the limiting block 1-1 from the third position C to the second position B. At this point, the spring force of the spring 6 lifts the dust cap 1 a certain distance, causing the limiting block 1-1 to enter the anti-detachment groove 2-3, preventing the limiting block 1-1 from detaching from the anti-detachment groove 2-3.
[0042] Example 2 like Figure 8-14 As shown, a flexible structure connector includes a dust cap 1, a housing 2, a spindle 3, a claw 4, and a tail sleeve 5; the claw 4 is disposed at the first end of the spindle 3 and the tail sleeve 5 is sleeved on the first end of the spindle 3; the dust cap 1 is sleeved on the second end of the spindle 3, and the housing 2 is sleeved on the outside of the dust cap 1; the inner wall of the housing 2 is provided with a limiting groove 2-1, and the outer side of the dust cap 1 is provided with a limiting block 1-1 that can move from the first position A to the second position B of the limiting groove 2-1.
[0043] A spring 6 is provided between the outer shell 2 and the main shaft 3. The outer shell 2 can rotate relative to the main shaft 3 to compress the spring 6, thereby causing the spring 6 to be in a compressed state. The main shaft 3 is a cylindrical structure with an arc-shaped spring receiving groove 3-2 on its surface. A push plate 2-4 is provided at a corresponding position on the inner side of the outer shell 2. One end of the spring 6 is connected to the spring receiving groove 3-2, and the other end extends out of the arc-shaped spring receiving groove 3-2 and abuts against the push plate 2-4. Since the spring receiving groove 3-2 is set on the circumferential surface of the main shaft 3, the other end can naturally extend and abut against the push plate 2-4, without the need to provide a through hole in the spring receiving groove 3-2.
[0044] like Figure 13-14 As shown, the spindle 3 is provided with a slot 3-1, the dust cap 1 is provided with a piece 1-4 that mates with the slot 3-1, and the limiting block 1-1 is located on the surface of the piece 1-4.
[0045] When the outer shell 2 is rotated, causing the spring 6 to be in a compressed state, the entrance of the limiting groove 2-1 coincides with the slot 3-1, allowing the dust cap 1 to be installed on the outer shell 2. When the limiting block 1-1 moves from the first position A to the third position C, the spring 6 resets and drives the outer shell 2 to rotate in the opposite direction through its elastic force, causing the limiting block 1-1 to move from the third position C to the second position B. In other words, in this embodiment, rotating the outer shell 2 to compress the spring 6 opens the channel for the dust cap 1 to enter the outer shell 2, allowing the limiting block 1-1 to enter the limiting groove 2-1.
[0046] When the limiting block 1-1 moves from the third position C to the second position B, one end of the spring 6 abuts against the outer shell 2 and the other end abuts against the main shaft 3, causing the limiting block 1-1 and the limiting groove 2-1 to be in abutting state.
[0047] Example 3 like Figure 15 As shown, the difference between Embodiment 3 and Embodiment 1 is that the free section of the second limiting segment 6-1-2 is shorter, which can reduce the overall length of the spring 6. When the limiting block 1-1 moves from the first position A to the third position C, the outer edge protrusion 1-3 of the dust cap 1 squeezes the elastic segment 6-2, causing the elastic segment 6-2 and the free section of the second limiting segment 6-1-2 to bend downwards; when the limiting block 1-1 moves from the third position C to the second position B, the outer edge protrusion 1-3 rotates relative to the elastic segment 6-2 and always squeezes the elastic segment 6-2; when the limiting block 1-1 moves to the second position B, the spring 6 lifts the dust cap 1, causing the limiting block 1-1 to enter the anti-detachment groove 2-3.
[0048] Example 4 like Figure 16 As shown, the difference between Embodiment 4 and Embodiment 1 is that an anti-rotation sleeve 7 is provided between the outer shell 2 and the tail sleeve 5. The outer shell 2 is provided with a first limiting tooth 2-5, and the anti-rotation sleeve 7 is provided with a second limiting tooth 7-1 that meshes with the first limiting tooth 2-5. When the bottom nut is tightened, the second limiting tooth 7-1 of the anti-rotation sleeve 7 and the first limiting tooth 2-5 of the outer shell 2 mesh with each other, and the outer shell 2 is limited and cannot rotate, further improving the connection stability between the dust cap 1 and the outer shell 2. When disassembly is required, the second limiting tooth 7-1 can be separated from the first limiting tooth 2-5 by rotating the nut in the opposite direction.
[0049] The above are merely preferred embodiments of the present invention. The scope of protection of the present invention shall be determined by the scope defined in the claims. Any improvements and modifications made by those skilled in the art without departing from the spirit and scope of the present invention shall also be considered as within the scope of protection of the present invention.
