Detailed Implementation

[0028] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0029] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0030] Reference Figures 1 to 8 As shown, this utility model embodiment provides a quick-release optical cable connector, including a connector housing 1 and a locking component 2.

[0031] The connector housing 1 has a channel 11 for the optical cable to pass through, and one end of the connector housing 1 is connected to two opposing clamping parts 12, through which the optical cable passes into the channel 11.

[0032] The locking component 2 is detachably mounted on the connector housing 1. When the locking component 2 is mounted on the connector housing 1, it locks with the housing and forces the two clamping parts 12 closer together to clamp the optical cable. When the locking component 2 is installed on the connector housing 1, it forms a locking relationship with the housing, and simultaneously uses mechanical force to push the two clamping parts 12 closer together. This design combines the locking and clamping actions into one, avoiding complex step-by-step operations, simplifying the usage process, and allowing users to easily fix the optical cable without needing professional skills.

[0033] In this embodiment, compared to traditional optical cable connectors that require tools and multiple precise steps, this quick-release connector is extremely fast to install. Installation is completed simply by passing the optical cable through the gap in the clamping part 12 and into the channel 11, then attaching the locking member 2. The entire process can be done manually, is quick, and greatly improves installation efficiency.

[0034] Furthermore, since the locking component 2 is detachable, disassembly is simple: just remove the locking component 2 from the connector housing 1, and the two clamping parts 12 will release external pressure, naturally releasing the optical cable, allowing it to be easily pulled out. When temporary replacement of optical cables or line maintenance is required, there is no need to painstakingly disassemble the complex structure, reducing maintenance time and difficulty.

[0035] In some practical applications, refer to Figures 4 to 5 As shown, the clamping part 12 is configured as a spring sheet structure or spring arm structure with one end connected to the end of the connector housing 1. The inner end of the clamping part 12 is provided with at least one barb structure 121 along the length direction of the connector housing 1. Each barb structure 121 is inclined towards the side of the clamping part 12 that is close to the connector housing 1.

[0036] One end of the spring clip or spring arm structure is connected to the end of the connector housing 1, while the other end is a free-moving end. When optical cables of different diameters are inserted, the clamping part 12 can adaptively deform to tightly fit the outer periphery of the optical cable. Compared with rigid clamping structures, it does not require precise matching of optical cable size, greatly expanding the compatibility of this quick-release connector with various specifications of optical cables.

[0037] The barb structure 121 is located on the inner end of the clamping part 12 and is angled towards the side of the clamping part 12 closest to the connector housing 1. When the optical cable is inserted, the barb hooks onto the outer sheath of the optical cable. When the optical cable is pulled by external force in an attempt to detach, the barb prevents the optical cable from being easily pulled out, thus enhancing the connection strength of the optical cable at the quick-release connector. It should be noted that the angle of the barb is designed according to the usage requirements over time. When the optical cable is inserted, it must be ensured that the barb only lightly scratches the outer sheath of the optical cable without causing significant damage. This ensures both the anti-detachment effect and maintains the integrity of the optical cable, without affecting the signal transmission performance of the internal optical fiber.

[0038] In some practical applications, refer to Figures 4 to 5 As shown, the inner end of the clamping part 12 is also provided with a protrusion 122; when the two clamping parts 12 are in an unloaded state, the distance between the two protrusions 122 is not less than the distance between the barb structures 121 on the two clamping parts 12. Therefore, when the two clamping parts 12 are brought closer together by the force of the locking member 2, the protrusion 122 can pre-press the outer side of the optical cable, and the barb structure 121 can further stabilize the connection effect of the optical cable. In addition, in practical applications, one side of the protrusion 122 is usually chamfered, which makes it easier for the optical cable to be inserted into the gap between the two clamping parts 12 from one side of the protrusion 122.

[0039] Reference Figures 4 to 5 As shown, in some practical applications, based on the above-mentioned clamping part 12 being configured as a spring sheet structure or a spring arm structure, the locking member 2 is configured as an internal threaded sleeve, and the two clamping parts 12 are provided with external threaded ends 13. The internal threaded sleeve is sleeved on the two clamping parts 12 and threadedly connected to the external threaded ends 13, so that the two clamping parts 12 are forced to move closer to each other under the pressure of the inner wall of the internal threaded sleeve.

[0040] When the internal threaded sleeve is not initially installed, the clamping part 12 naturally opens and slightly tilts outward, allowing the optical cable to easily slide between the two clamping parts 12 without requiring additional effort to open it. When the internal threaded sleeve is fitted onto the two clamping parts 12, its inner wall presses against the free end of the clamping part 12, causing the two clamping parts 12 to evenly close inward, thus tightening the optical cable. Unlike some asymmetrical or single-point pressure clamping methods, this mode of simultaneous compression from both sides ensures uniform force on all parts of the optical cable circumference, effectively preventing problems such as optical cable deformation and internal fiber twisting caused by uneven local force, ensuring stable signal transmission. As the internal threaded sleeve is continuously screwed in, the clamping force gradually increases. Operators can precisely control the clamping force. The entire installation process can be completed by hand, without complicated tool operations or fine adjustments. Whether it is a professional telecommunications engineer or a general maintenance personnel handling temporary emergencies, they can quickly get started and easily complete the connection and fixation of the optical cable, greatly improving the efficiency of emergency repairs and daily maintenance.

[0041] Additionally, a first limiting wall 14 can be provided on the connector housing 1, and the internal thread abuts against the first limiting wall 14 to achieve axial limiting. Figure 5 As shown, the outer wall of the internal threaded sleeve is also provided with several grooves to facilitate the tightening of the internal threaded sleeve by the workers.

[0042] Reference Figures 1 to 8 As shown, an optical cable connector includes a housing assembly 3, and the optical cable quick-release connector in any of the above embodiments can be installed inside the housing assembly 3.

[0043] In some practical applications, the housing assembly 3 also includes a dust cap 31, the threaded portion 311 of which is threaded onto the optical cable quick-release connector.

[0044] Reference Figures 1 to 8 As shown, in some practical applications, the housing assembly 3 includes a middle shell 32, a sealing plug 33, a locking nut 34, and a connector housing 35.

[0045] The inner wall of the middle shell 32 has an inwardly protruding first limiting part 321 and a second limiting part 322 located on its outer wall. The middle shell 32 is fitted onto the connector shell 1, and the first limiting part 321 abuts against the third limiting wall 15 on the connector shell 1. The first limiting part 321 on the inner wall of the middle shell 32 abuts against the third limiting wall 15 of the connector shell 1, accurately determining the axial position of the middle shell 32 fitted onto the connector shell 1, preventing unnecessary displacement of the two in the axial direction, and ensuring the stability of the overall structure. The second limiting part 322 located on the outer wall provides a positioning reference for the subsequent fitting of the connector shell 35. This method of inner and outer limiting cooperation makes the assembly process more intuitive and convenient, and reduces the assembly difficulty.

[0046] The sealing plug 33 is inserted into the inner shell 32 and abuts against the locking member 2. The sealing plug 33 has a through hole 331 for the optical cable to pass through. The sealing plug 33 can effectively prevent external dust, moisture and other impurities from entering the connector. The sealing plug 33 also plays a certain auxiliary fixing role for the locking member 2, preventing the locking member 2 from loosening due to accidental vibration or shaking, indirectly stabilizing the clamping state of the two clamping parts 12 on the optical cable, and further improving the reliability of the optical cable connection.

[0047] The locking nut 34 has a fourth limiting wall 341 inside. The locking nut 34 is threaded to the first threaded end 323 of the middle shell 32, and the fourth limiting wall 341 abuts against the first threaded end 323. The connector housing 35 has an internal threaded groove 351. The connector housing 35 is sleeved on the middle shell 32, and one end of the internal threaded groove 351 abuts against the second limiting part 322. As the outermost layer of protection, the connector housing 35 can resist a certain degree of mechanical impact and scratch.

[0048] In some practical applications, refer to Figures 1 to 3As shown, the housing assembly 3 also includes a dust cap 31. Specifically, the threaded portion 311 of the dust cap 31 is threaded into the internal threaded groove 351, and the threaded portion 311 abuts against the end of the middle shell 32. When the threaded portion 311 of the dust cap 31 is screwed into the internal threaded groove 351 and abuts against the end of the middle shell 32, the axial force it generates cleverly pulls the connector housing 35, making it tightly abut against the second limiting portion 322 of the middle shell 32. A tight and stable connection is formed between the components, allowing the housing assembly 3 to better withstand external impact and tension, as well as internal stress caused by temperature changes, reducing the possibility of component loosening or displacement, and creating a stable working environment for the internal optical cable connection structure. In addition, the assembly of traditional complex structures often requires multiple processes to precisely position and fix different components. With the dust cap 31, simply screwing in the dust cap 31 can simultaneously complete the calibration and fixation of the connector housing 35, achieving complete assembly of the entire housing assembly 3 and simplifying the assembly process.

[0049] In some practical applications, refer to Figure 2 and Figure 8 As shown, a tail sleeve 36 is fitted onto the outside of the locking nut 34. The tail sleeve 36 has a fifth limiting wall 361 and a through hole 362 for the optical cable to pass through. An inner protrusion 363 is also formed at the front end of the tail sleeve 36. The inner protrusion 363 and the fifth limiting wall 361 respectively abut against the two ends of the locking nut 34. The tail sleeve 36 provides an additional layer of protection for the optical cable.

[0050] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
