A modular connector fiber optic transmission line

Abstract

This utility model discloses a modular connector fiber optic transmission line, relating to the field of fiber optic connector technology. It includes a line body, one end of which is fixedly connected to a first connector. A splicing assembly is engaged with one side of the first connector, and a second connector is engaged with the other end of the splicing assembly. The splicing assembly includes a connecting sleeve. This modular connector fiber optic transmission line achieves rapid splicing and positioning by engaging the connecting sleeve with the outside of the first connector and applying pressure. The sliding sleeve is obstructed and slides, compressing a connecting spring and disengaging from the positioning block. The supporting spring then lifts the positioning block, allowing it to slide into the positioning hole on the side plate. The dual positioning of the sliding sleeve and the positioning block greatly improves connection stability. Through simple operation, the first connector and the connecting sleeve can be quickly spliced ​​and positioned or separated. When a connector is damaged, it is not necessary to replace the entire transmission line; only the corresponding connector needs to be replaced, significantly reducing usage costs and resource waste.

Description

Technical Field

[0001] This utility model relates to the field of optical fiber connector technology, specifically to an optical fiber transmission line with a modular connector. Background Technology

[0002] Fiber optic transmission lines are optical transmission tools that utilize the principle of total internal reflection of light within fibers made of glass or plastic. They play a crucial role in modern communication and data transmission, possessing numerous significant advantages: extremely high transmission rates, easily handling the rapid transmission of massive amounts of data, meeting the stringent speed requirements of high-definition video and large file transfers; long transmission distances; low signal attenuation, maintaining high quality over long distances; and widespread application in intercity and international communication networks. They also have strong anti-interference capabilities, are unaffected by electromagnetic interference, and ensure the stability and accuracy of data transmission. Fiber optic transmission lines consist of a fiber core, cladding, and coating. The fiber core transmits optical signals, the cladding enables total internal reflection within the core, and the coating provides protection. With the development of information technology, the application scenarios of fiber optic transmission lines are becoming increasingly widespread, from home broadband to enterprise data centers, from communication base stations to intelligent transportation systems, all relying on their presence and providing solid support for the informatization development of modern society.

[0003] In existing technologies, the fixed installation of optical fibers and connectors, such as USB, HDMI, and DP connectors, has significant drawbacks. These connectors cannot be replaced, and once damaged, the entire optical fiber transmission line will become unusable. Compared to optical fibers, connectors have a higher failure rate and shorter lifespan, which greatly increases the risk of failure. When a connector fails, not only will the transmission function fail, but the entire optical fiber transmission line will also be wasted, leading to increased operating costs. Therefore, we need an optical fiber transmission line with modular connectors. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a modular connector fiber optic transmission line, comprising a line body, one end of which is fixedly connected to a first connector, a splicing assembly is snapped onto one side of the first connector, and a second connector is snapped onto the other end of the splicing assembly; the splicing assembly includes a connecting sleeve, which is snapped onto the outside of the first connector, a side plate is fixedly connected inside the connecting sleeve, a positioning hole is provided inside the side plate, a connecting spring is fixedly connected to one side of the first connector, a sliding sleeve is fixedly connected to one end of the connecting spring, a support spring is fixedly connected to the outer wall of the first connector, a positioning block is fixedly connected to one end of the support spring, and a pressing plate is fixedly connected to one side of the positioning block.

[0006] Preferably, the first connector forms a supporting elastic structure with a connecting spring and a sliding sleeve, and the connecting spring is disposed between the first connector and the sliding sleeve.

[0007] Preferably, the side plate forms a locking structure with the positioning block through a positioning hole, and the size of the positioning hole is larger than the size of the positioning block, and one end of the positioning block is locked in the positioning hole for installation.

[0008] Preferably, the pressing plate forms a linkage structure with the positioning block through the support springs, and there are multiple support springs, all of which are arranged on one side of the pressing plate and the positioning block.

[0009] Preferably, the insertion assembly includes an optical fiber plug, and the optical fiber plug is fixed to one side of the first connector.

An optical fiber insert plate is fixedly connected to one side of the second connector, and a friction pad is fixedly connected inside the optical fiber insert plate. A retaining plate is fixedly connected inside the optical fiber plug.

[0010] Preferably, the fiber optic plug-in plate forms a friction plug-in structure with friction pads and bumps, and the friction pads are evenly distributed on the inner wall of the fiber optic plug-in plate, and the inner wall of the friction pads is fitted to the outer wall of the bumps.

[0012] Compared with the prior art, the beneficial effects of this utility model are: this modular connector fiber optic transmission line...

[0013] (1) By engaging the connecting sleeve with the outside of the first connector and applying pressure to it, the sliding sleeve is blocked and slides and squeezes the connecting spring, thus breaking away from the block. The supporting spring lifts the positioning block and slides it into the positioning hole of the side plate, achieving quick splicing and positioning. The dual positioning of the sliding sleeve and the positioning block greatly improves the connection stability. When disassembling, pull the sliding sleeve to squeeze the connecting spring, allowing the positioning block to move in the positioning hole. Then press the pressing plate to compress the supporting spring, and the positioning block can be released from the positioning hole, unlocking and achieving separation. Through simple operations such as pressing and pulling, the first connector and the connecting sleeve can be quickly spliced ​​and positioned or separated. When the connector is damaged, there is no need to replace the entire transmission line; only the corresponding connector needs to be replaced, which greatly reduces the cost of use and resource waste. Different interfaces can be switched, making it more applicable and applicable to a wider range of scenarios.

[0014] (2) Through the interlocking connection between the fiber optic plug and the fiber optic connector, and the tight fit between the friction pad inside the fiber optic plug and the outer wall of the protrusion, plus the locking cooperation between the plug and the slot, the multi-level and multi-mode connection and fixation effectively prevents the connector from loosening or falling off during use, ensuring the stability and reliability of signal transmission, providing a solid guarantee for data transmission and other applications. Users can easily and quickly replace different types of connectors according to actual usage needs, improving the utilization rate of the fiber optic transmission line. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model embodiment provides a modular connector fiber optic transmission line, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the device includes a cable body 1, with a first connector 2 fixedly connected to one end. A splicing assembly 3 is snapped onto one side of the first connector 2, and a second connector 4 is snapped onto the other end of the splicing assembly 3. The other end of the second connector 4 can be connected to a transmission connector such as HDMI, DP, or USB as needed. The splicing assembly 3 includes a connecting sleeve 301, which is snapped onto the outside of the first connector 2. A side plate 302 is fixedly connected inside the connecting sleeve 301, and a positioning hole 303 is provided inside the side plate 302. A connecting spring 304 is fixedly connected to one side of the first connector 2, and a sliding sleeve 305 is fixedly connected to one end of the connecting spring 304. A support spring 306 is fixedly connected to the outer wall of the first connector 2, and a positioning block 307 is fixedly connected to one end of the support spring 306. A pressing plate 308 is fixedly connected to one side of 07. When pressure is applied to the first connector 2 and the connecting sleeve 301 by hand, the sliding sleeve 305 outside the first connector 2 is blocked by the connecting sleeve 301. The sliding sleeve 305 slides on the outer wall of the first connector 2 and squeezes the connecting spring 304. At this time, the sliding sleeve 305 is released from blocking the positioning block 307. The support spring 306 on the outer wall of the first connector 2 pushes the positioning block 307 outward, so that one side of the positioning block 307 slides along the surface of the side plate 302. When it slides into the positioning hole 303 of the side plate 302, the first connector 2 and the connecting sleeve 301 can be quickly spliced ​​and positioned by the push of the support spring 306. Under the support of the sliding sleeve 305 and the dual stable positioning of the positioning block 307, the connection stability can be further improved.

[0023] Further such as Figure 2 and Figure 3 The first connector 2 forms a support elastic structure with the connecting spring 304 and the sliding sleeve 305. The connecting spring 304 is located between the first connector 2 and the sliding sleeve 305. By setting the connecting spring 304 between the first connector 2 and the sliding sleeve 305, the connecting spring 304 can be used to support and limit the sliding sleeve 305.

[0024] Further such as Figure 3 and Figure 4 As shown, the side plate 302 forms a locking structure with the positioning block 307 through the positioning hole 303, and the size of the positioning hole 303 is larger than the size of the positioning block 307. One end of the positioning block 307 is installed by locking it in the positioning hole 303. By setting the positioning hole 303 on the side plate 302, the positioning block 307 can be locked in the positioning hole 303 for positioning and installation, which can facilitate the quick splicing of the first connector 2 and the connecting sleeve 301.

[0025] Further such as Figure 2 and Figure 3As shown, the pressing plate 308 forms a linkage structure with the positioning block 307 through the support spring 306, and there are multiple support springs 306. All the support springs 306 are arranged on one side of the pressing plate 308 and the positioning block 307. By setting the support spring 306 between the pressing plate 308 and the positioning block 307, the support spring 306 can be used to support and limit the pressing plate 308 and the positioning block 307.

[0026] In a further preferred embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the insertion assembly 5 includes an optical fiber plug 501, which is fixed to one side of the first connector 2. A protrusion 502 is fixedly connected to the outer wall of the optical fiber plug 501, and a slot 503 is provided inside the protrusion 502. An optical fiber insert plate 504 is fixedly connected to one side of the second connector 4, and a friction pad 505 is fixedly connected inside the optical fiber insert plate 504. A locking plate 506 is fixedly connected inside the optical fiber plug 501. The optical fiber insert plate 504 on the second connector 4 engages with the outer wall of the optical fiber plug 501 on the first connector 2 for connection. When the optical fiber insert plate 504 continues to extend, it will be locked onto the outer wall of the protrusion 502, and the friction pad 505 inside the optical fiber insert plate 504 will adhere to the outer wall of the protrusion 502 for secure installation. At the same time, the locking plate 506 inside the optical fiber insert plate 504 can be locked in the slot 503 on the outer wall of the protrusion 502 for locking. This further improves the connection stability between modular connectors and allows for quick replacement and installation of different connectors according to usage needs.

[0027] Further such as Figure 3 and Figure 5 As shown, the fiber optic plug 504 forms a friction plug structure with the protrusion 502 through the friction pad 505, and the friction pad 505 is evenly distributed on the inner wall of the fiber optic plug 504. The inner wall of the friction pad 505 is fitted to the outer wall of the protrusion 502. By setting the friction pad 505 on the fiber optic plug 504, the connection stability between the first connector 2 and the second connector 4 can be further strengthened by the blocking and friction of the friction pad 505 when the protrusion 502 is inserted.

[0028] Further such as Figure 5As shown, the fiber optic connector 504 forms a locking structure with the protrusion 502 via the locking plate 506. The outer diameter of the locking plate 506 matches the inner diameter of the slot 503 on the protrusion 502, and the outer wall of the locking plate 506 fits against the inner wall of the slot 503. By setting the locking plate 506 on the fiber optic connector 504, and when the fiber optic connector 501 is inserted into the fiber optic connector 504, the external protrusion 502 can be inserted into the fiber optic connector 504, and the locking plate 506 is locked in the slot 503 for limiting and reinforcement, which improves the connection stability between the first connector 2 and the second connector 4.

[0029] Working principle: During assembly, the connecting sleeve 301 can be snapped onto the outside of the first connector 2, and the connecting sleeve 301 and the sliding sleeve 305 are fitted together. Simultaneously, pressure is applied to the first connector 2 and the connecting sleeve 301, causing the sliding sleeve 305 on the outside of the first connector 2 to be blocked by the connecting sleeve 301. The sliding sleeve 305 slides on the outer wall of the first connector 2 and compresses the connecting spring 304. At this time, the sliding sleeve 305 disengages from blocking the positioning block 307, and the support spring 306 on the outer wall of the first connector 2 pushes the positioning block 307 outwards. This allows the positioning block 307 to slide along the surface of the side plate 302. When it slides into the positioning hole 303 of the side plate 302, the first connector 2 and the connecting sleeve 301 are quickly spliced ​​and positioned by the push of the support spring 306. Furthermore, the connection stability is further improved by the support of the sliding sleeve 305 and the dual stable positioning of the positioning block 307. If disassembly is required, the sliding sleeve 305 is pulled backward to compress the connecting spring 304, allowing the positioning block 307 to move within the positioning hole 303. At this time, pressure is applied to the pressing plate 308. Force compresses the supporting spring 306, causing the positioning block 307 to disengage from the positioning hole 303, releasing the lock on the connecting sleeve 301, thereby separating the first connector 2 from the connecting sleeve 301. The entire process is simple to operate, allowing users to modularly assemble and disassemble according to actual needs. Simultaneously, the second connector 4 from USB, HDMI, DP, etc., is inserted into the connecting sleeve 301 in the same manner. During this process, the fiber optic plug 504 on the second connector 4 engages with the outer wall of the fiber optic plug 501 on the first connector 2 for connection. As plate 504 continues to extend, it will cause fiber optic insert 504 to be locked onto the outer wall of protrusion 502, and the friction pad 505 inside fiber optic insert 504 to adhere to the outer wall of protrusion 502 for secure installation. At the same time, the locking plate 506 inside fiber optic insert 504 can be locked into the slot 503 on the outer wall of protrusion 502 for locking. This further improves the connection stability between modular connectors, allows for quick replacement and installation of different connectors according to usage needs, enables switching between different interfaces, enhances applicability, and broadens the application scenarios.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
