Description
Technical Field
[0001] This invention belongs to the technical field of connectors, specifically relating to an optoelectronic composite cable connector and its method. Background Technology
[0002] With the advancement of network technology, optoelectronic composite cables, integrating power transmission and optical signal transmission, have become key cables in many fields such as modern communications, power distribution, and marine engineering. The accelerating pace of global digitalization, the transformation of energy structures, and the continued deepening of marine resource development present new opportunities and challenges for optoelectronic composite cables. Against this backdrop, optoelectronic composite connectors closely follow technological progress, excelling in research and innovation and making greater contributions to the continued prosperity of the optoelectronic composite cable industry.
[0003] The connectors currently used in the market have the following drawbacks: 1. Higher cost: As a disposable consumable, the price of a single cold-joint is higher than that of fusion welding materials; 2. Mechanical connection risk: Signal distortion is easily caused by optical axis misalignment, requiring strict operation to ensure end face alignment; 3. Maintenance cost: After long-term use, it may need to be replaced due to aging or wear, resulting in high maintenance costs; 4. Loss fluctuation: Although the loss is usually ≤0.3dB, it may exceed 0.5dB in extreme cases, indicating slightly poor stability.
[0004] The technical design of the optoelectronic composite connector encompasses multiple aspects, including material selection, structural optimization, and process improvement. In terms of materials, it possesses the conductivity, optical signal transmission efficiency, and durability of cables; structurally, it balances the transmission requirements of both electrical and optical signals to ensure high efficiency; and process improvements are key to continuously increasing production efficiency, reducing costs, and guaranteeing product quality. Through these technical design and optimizations, the optoelectronic composite connector not only overcomes the shortcomings of existing products but also has a wider range of applications. Summary of the Invention
[0005] The purpose of this invention is to address the aforementioned shortcomings in the prior art by providing an optoelectronic composite cable connector and method, thereby solving the problem that existing connectors cannot simultaneously satisfy the compatible transmission and connection of optical and electrical signals.
[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: In a first aspect, there is an optoelectronic composite cable connector, which includes an upper component, a middle component, and a lower component arranged in an integrated three-section layout; the upper component and the lower component are respectively snapped together with the middle component. The intermediate component includes a main body, needles, and an inner core; multiple sets of needles are inserted into the middle and tail ends of the main body; the inner core is installed in the center of the inner cavity of the main body, and the inner core is provided with inner core limiting V-groove steps at both ends of the inner cavity of the main body for positioning the inner core and simultaneously for fixing and leveling the optical fiber core; both ends of the main body are provided with flip-top type clamping buckles, which are closed and locked by tail caps to clamp the optical cable. At the same time, when the flip-top type clamping buckles are closed and pressed down, the tips of the needles at the tail end penetrate the conductive copper wires inside the optical cable sheath for electrical transmission.
[0007] Furthermore, the inner cavity of the main body is provided with an inner core mounting slot, and the two side walls at the midpoint of the inner core mounting slot are provided with 4 sets of needle fixing slots, and the two tail ends of the main body are each provided with 2 sets of needle fixing slots; the head and tail of the needle are respectively locked into the needle fixing slots for fixation.
[0008] Furthermore, the tail end of the needle is pointed.
[0009] Furthermore, locking threads are provided at both ends of the main body, and the outer end of the locking threads is a flip-top type clamping buckle; the flip-top type clamping buckle clamps the optical cable by covering and locking the tail cap.
[0010] Furthermore, both the flip-top clamping buckle and the tail end of the main body are provided with a serrated inverted buckle shape to clamp and hold the optical cable tightly.
[0011] Furthermore, the main body and the flip-top snap fastener have a positive electrical conduction marking on their connecting side wall.
[0012] Furthermore, the lower component includes a lower cover and an LED light assembly; the lower cover is snapped into the lower part of the middle section of the main body, and the lower cover has a highly transparent groove design, with the LED light assembly fixed in the groove of the lower cover and connected to the contact point of the needle.
[0013] Furthermore, the lower cover is provided with a snap-fit buckle, which is snapped into and fixed to the main body with a pre-reserved snap-fit plane; the lower cover is provided with positive and negative electrode markings and different openings for preventing misalignment according to direction.
[0014] Furthermore, the upper component includes an upper cover and a key; the upper cover is inserted into the upper part of the middle part of the main body, and two sets of positioning ramps are provided at each end of the inner wall of the upper cover. After the upper cover is inserted into the main body, the two sets of ramps are pressed down on the outer wall of the inner core, and the outer wall of the inner core is pulled inward to hug the optical cable; the key is inserted through the key mounting position in the center of the upper cover to clamp and fix the optical cable connection part again.
[0015] Secondly, a splicing method for an optoelectronic composite cable connector includes the following steps: S1. Insert the head and tail of the needle into the needle fixing position of the main body in sequence to fix them. S2. Install the inner core into the center of the main body cavity. The inner core installation limiting V-groove steps at both ends of the inner core are used to position the inner core installation and also to fix the fiber core and assist in leveling and docking. S3. Insert the two optical cables into both ends of the main body respectively, and align the optical cable sheath with the tip of the needle; S4. Cover the main body with the flip-top clamping buckle and tighten the tail cap at the end of the main body. The flip-top clamping buckle and the serrated buckle at the end of the main body, along with the tail cap, work together to hold the optical cable tightly. When the flip-top clamping buckle is pressed down, the spikes of the needle penetrate the photoelectric wire and come into contact with the internal conductive copper wire, thus enabling the two optical cables to conduct electricity. S6. Install the LED light assembly into the groove of the lower cover, and make electrical contact between the LED light assembly plug and the needle; align the anti-misalignment directional step of the lower cover with the corresponding structure of the main body, and engage the lower cover buckle with the reserved plane of the main body; If the power supply is normal, the LED lights will automatically turn on, and the installation will be deemed "qualified" immediately; if the lights do not turn on, the contact problem will be checked directly, and no additional equipment is required for verification. S7. Attach the top cover to the top of the main body using the top cover buckle. The positioning ramp on the inner wall of the top cover will press down on the outer wall of the inner core, causing the inner core to retract and hold the optical cable tightly, thus achieving auxiliary positioning of the optical cable. Insert the key through the center mounting position of the top cover to further clamp the optical cable connection part, ensuring that the optical fiber core is completely leveled and aligned in the inner core limiting V-groove step.
[0016] The optoelectronic composite cable connector and method provided by this invention have the following beneficial effects: This invention has advantages such as integration, high efficiency, anti-interference ability, cost saving and convenient construction, and solves the problem of the single function of existing products; the electrical signals and optical signals of the whole product are transmitted through different paths, reducing mutual interference.
[0017] In this invention, the optical fiber signal is transmitted through the inner core limiting V-groove step docking path, while the power is transmitted through the puncture contact path of the needle. The two paths are separated to reduce mutual interference, and ultimately achieve synchronous and stable transmission of optical signal and power.
[0018] This invention, an optoelectronic composite connector, integrates optical fiber and power transmission functions into the connector, simplifying wiring, reducing cable procurement and construction costs, and lowering subsequent maintenance costs. It also meets the high-quality, high-bandwidth access requirements of modern networks, satisfies the needs of 4K / 8K high-definition monitoring, supports power transmission to solve equipment power supply issues, achieves comprehensive network coverage, features a mechanical contact-free design (such as optical couplers), has a lifespan exceeding 100,000 hours, reduces the failure rate, is compatible with multiple transmission protocols, and supports future technology upgrades.
[0019] This invention integrates fiber optic signal transmission and power transmission functions into the same connector, and solves the anti-interference problem through "different path transmission"; it adds real-time installation quality detection of LED light groups, eliminating the need for repeated equipment verification and filling the gap in existing technology where "quality cannot be determined immediately after installation"; it integrates multiple foolproof and fixing structures such as positive and negative polarity markings, anti-mistake directional steps on the lower cover, serrated inverted buckles, and three-section buckles.
[0020] This invention proposes a three-section integrated layout (central optical / electrical core component, upper fixing component, and lower detection component), which integrates optical signal leveling and connection with power puncture conduction, fundamentally improving the product structure.

[0027] The specific embodiments of the present invention are described below to enable those skilled in the art to understand the present invention. However, it should be understood that the present invention is not limited to the scope of the specific embodiments. For those skilled in the art, various changes are obvious as long as they are within the spirit and scope of the present invention as defined and determined by the appended claims. All inventions utilizing the concept of the present invention are protected.
[0028] This embodiment provides an optoelectronic composite cable connector, referencing... Figure 1It includes an integrated layout in three sections: upper, middle, and lower. The upper and lower components are connected to the middle component by clips.
[0029] In some embodiments, the middle component includes a body 1, a needle 6, and an inner core 7; refer to Figure 4 The inner cavity of the main body 1 is provided with an inner core mounting slot. The inner core mounting slot has four sets of needle fixing slots 10 on both sides of the midpoint. The two tail ends of the main body 1 are each provided with two sets of needle fixing slots 10. The head and tail of the needle 6 are respectively inserted into the needle fixing slots 10 for fixation. After multiple sets of needles 6 are inserted into the middle and tail ends of the main body 1, the inner core 7 is installed in the center of the inner cavity of the main body 1. The inner core limiting V-groove steps 11 are provided at both ends of the inner cavity of the main body 1, which are used to position the inner core 7 and at the same time to fix and level the fiber core.
[0030] Both ends of the main body 1 are provided with locking threads 15. The outer end of the locking threads 15 is a flip-type clamping buckle 9. The flip-type clamping buckle 9 is covered and locked by the tail cap 5, thereby clamping the optical cable. At the same time, when the flip-type clamping buckle 9 is closed and pressed down, the tail end of the needle 6 is sharp. The sharp corner of the needle 6 at the tail end penetrates the conductive copper wire inside the optical cable to conduct electricity.
[0031] refer to Figure 5 The flip-top clamping buckle 9 clamps the optical cable by covering and locking it into the tail cap 5. Both the flip-top clamping buckle 9 and the tail end of the main body 1 are provided with a serrated inverted shape to bite and hold the optical cable tightly. The connecting side wall of the main body 1 and the flip-top clamping buckle 9 is provided with an electrical transmission positive terminal mark, namely electrode mark 12, which can effectively prevent the positive and negative terminals from being reversed during use, resulting in no power supply.
[0032] In some embodiments, reference Figure 2 and Figure 3 The lower component includes a lower cover 2 and an LED light group 8. The lower cover 2 is snapped into the lower part of the middle part of the main body 1. The lower cover 2 has a highly transparent groove design. The LED light group 8 is fixed in the groove of the lower cover 2 and connected to the contact point of the needle 6.
[0033] In one specific embodiment, reference is made to Figure 2 and Figure 3The lower cover 2 features a highly transparent concave design, which secures the LED within the recessed area, preventing poor contact between the LED assembly 8 plug and the needle 6 during installation. The lower cover 2 also includes positive and negative electrode markings and a directional anti-misalignment opening to further prevent incorrect installation. The lower cover 2 features a snap-fit buckle that engages with the pre-drilled surface of the main body 1. To further ensure a tight fit between the lower cover 2 and the main body 1, three-section snap-fits are provided on both sides of the lower cover 2 and the main body 1, ensuring a more secure and drop-resistant fit.
[0034] After the spike at the tail of the needle 6 pierces the optoelectronic composite cable, the device is powered on and connected to the circuit. The plug of the LED light group 8 connects to the contact point of the needle 6, causing the LED light group 8 to light up as an indicator. This ensures that the installation quality of the connector can be judged during the installation process without the need for repeated connection to the device for confirmation. Simultaneously, to effectively increase the lifespan of the LED light group 8, the lower cover 2 is designed with heat dissipation holes to dissipate the heat generated by the LED light group 8 during use, reducing the risk of LED light group 8 malfunctioning or failing to light up due to ineffective heat dissipation.
[0035] In some embodiments, reference Figure 4 The upper component includes an upper cover 3 and a key 4; The upper cover 3 is inserted into the middle part of the main body 1. Each end of the inner wall of the upper cover 3 is provided with a set of positioning ramps. After the upper cover 3 is inserted into the main body 1, the two sets of ramps press down on the outer wall of the inner core 7. The outer wall of the inner core 7 is forced inward and hugs the optical cable, and the optical cable is positioned again. The key 4 is inserted through the key mounting position in the center of the upper cover, and the optical cable connection part is clamped and fixed again, thereby improving the stability and quality of the optical signal.
[0036] Secondly, a splicing method for an optoelectronic composite cable connector, referencing... Figures 1-5 This includes the following steps: S1. Insert the head and tail of the needle 6 into the needle fixing slot 10 of the main body 1 in sequence to fix them. S2. Install the inner core 7 into the center of the inner cavity of the main body 1. The inner core installation limiting V-groove steps at both ends of the inner cavity position the inner core 7 and are also used for fixing the fiber core and assisting in leveling and docking. S3. Insert the two optical cables into both ends of the main body 1 respectively, and align the optical cable sheath with the tip of the barbed needle 6. S4. Cover the flip-top clamping buckle 9 of the main body 1 and screw the tail cap 5 onto the tail end of the main body 1. The flip-top clamping buckle 9 and the serrated buckle at the tail end of the main body 1, together with the tail cap 5, hold the optical cable tightly. When the flip-top clamping buckle 9 is pressed down, the spikes of the needle 6 penetrate the photoelectric wire and come into contact with the internal conductive copper wire, so as to realize the power conduction of the two optical cables. S6. Install the LED light group 8 into the groove of the lower cover 2, and make electrical contact between the plug of the LED light group 8 and the needle 6; align the anti-misalignment directional step 16 of the lower cover 2 with the corresponding structure of the main body 1, and engage the lower cover buckle 13 with the reserved plane of the main body 1. If the power supply is normal, LED light group 8 will automatically light up, and the installation will be deemed "qualified" immediately; if the lights do not light up, the contact problem will be checked directly, and no additional equipment is required for verification. S7. The upper cover 3 is inserted into the upper body 1 through the upper cover buckle 14. The positioning inclined platform on the inner wall of the upper cover 3 is pressed down on the outer wall of the inner core 7, and the inner core 7 retracts and hugs the optical cable to achieve auxiliary positioning of the optical cable. Insert key 4 through the center mounting position of the upper cover 3 to further clamp the optical cable connection part, ensuring that the optical fiber core is completely leveled and aligned in the inner core limiting V groove step 11. Although specific embodiments of the invention have been described in detail with reference to the accompanying drawings, this should not be construed as limiting the scope of protection of this patent. Various modifications and variations that can be made by a person skilled in the art without inventive effort within the scope described in the claims still fall within the scope of protection of this patent.
