Description

Technical Field

[0001] This utility model belongs to the technical field of optoelectronic connectors, specifically, it relates to an abrasive optoelectronic connector. Background Technology

[0002] The primary function of optoelectronic connectors is to enable bidirectional transmission of optical and electrical signals, while providing stable physical connections and electrical contacts. They combine the high bandwidth of fiber optic transmission with the power supply functionality of power circuits, making them widely used in communications, photovoltaic systems, and other fields. Optoelectronic connectors integrate electrical contacts into a pure optical connector, enabling simultaneous fiber optic signal transmission (such as data and video) and power supply (such as device drives and sensor power). The optical signal channel utilizes high-precision fiber optic splicing technology to ensure low-loss transmission, while the electrical signal channel uses copper conductors or special alloy materials to conduct current, meeting different power requirements. When connecting optical fibers and connectors, optoelectronic connectors require adhesive for fixation and ultraviolet light irradiation for accelerated curing. However, existing optoelectronic connector housings have poor light transmittance, affecting curing efficiency. Furthermore, connecting the wires on both sides of the optical fiber bus requires removing the insulation with tools, resulting in low connection efficiency.

[0003] In view of this, this utility model is proposed. Utility Model Content

[0005] A grinding-type optoelectronic connector includes a housing and a matching cover. The housing has symmetrically arranged rotating flanges on both sides of its middle section, and symmetrically arranged locking blocks on both sides of one end of the housing. One end of the cover has a rotating connection end with rotating holes on both sides. The outer side of the cover, away from the rotating holes, has a locking groove. The cover and housing are rotatably connected via the rotating flanges and rotating holes. An optoelectronic busbar holder is provided inside the housing. Mounting grooves are formed between the two sides of the optoelectronic busbar holder and the inner wall of the housing. Two copper plates, copper sheet one and copper sheet two, are symmetrically installed in the two mounting grooves. Each copper plate has a wire contact end at one end of the locking block on the housing. A wire stripping fixing tooth is provided at the inner top of the cover. Through the engagement of the wire stripping fixing tooth and the wire contact end, the protective layer of the wire can be crushed and destroyed, allowing the metal core inside the wire to effectively contact the wire contact end.

Rotating flanges 5 are symmetrically arranged on both sides of the middle of the housing 1, and locking blocks 7 are symmetrically arranged on both sides of one end of the housing 1. A rotating connection end 10 is provided at one end of the pressure cap 2, with rotating mating holes 9 on both sides of the rotating connection end 10. A locking groove 8 is provided at the outer end of the pressure cap 2 away from the rotating mating holes 9. The pressure cap 2 and the housing 1 are rotatably connected through the rotating flanges 5 and the rotating mating holes 9. An optical cable is installed inside the housing 1. The mounting base 20 has mounting grooves 21 formed between its two sides and the inner wall of the housing 1. Copper sheet 11 and copper sheet 22 are symmetrically installed in the two mounting grooves 21. Copper sheet 11 and copper sheet 22 are respectively provided with wire contact ends 14 at one end of the locking block 7 of the housing 1. The inner top of the pressure cover 2 is provided with wire stripping fixing teeth 15. Through the cooperation of wire stripping fixing teeth 15 and wire contact ends 14, the protective layer of the wire can be crushed and destroyed, so that the metal core inside the wire can effectively contact the wire contact ends 14.

[0027] The rotating flange 5 and the locking block 7 are both provided with mounting guide slopes 6 on their upper parts, and the locking groove 8 is a rectangular through groove structure used to lock the installation state of the two pressure caps 2.

[0028] The positions of the two wire contact ends 14 on copper sheet 11 and copper sheet 2 12 correspond to the positions of the wires on both sides of the optical cable busbar to ensure the connection of the electrical channel.

[0029] A mating support boss 22 is provided on the outer side of the housing 1 near the rotating mating flange 5. A limit block 24 is provided on the side of the mating support boss 22 away from the rotating mating flange 5. The copper sheet 11 and the copper sheet 22 are provided with mating support grooves 23 and limit ends 25. The shape and specifications of the mating support boss 22 and the mating support groove 23 are adapted to each other to support and limit the installation of the copper sheet 11 and the copper sheet 22.

[0030] The optical fiber busbar placement base 20 has a U-shaped groove in the middle, and multiple bosses are provided on the outer side of the optical fiber busbar placement base 20 to improve the stability of the copper sheet installation.

[0031] A through hole 26 is provided at the center of the end of the housing 1 away from the pressure cover 2. A ferrule 17 is installed in the through hole 26. A mating mounting hole 18 is provided on the partition in the middle of the housing 1. The shape and specifications of the long end of the ferrule 17 passing through the through hole 26 from the mating mounting hole 18 are adapted to the shape and specifications of the large end of the ferrule 17.

[0032] The outer side of the ferrule 17 is provided with a limiting flange 19, which is a conical structure. The large end of the ferrule 17 is provided with a recessed groove, in which a ceramic ferrule 4 is installed. A blue card 3 is sleeved on the outer side of the housing 1. A limiting plate 16 is provided on the bottom surface of the housing 1. An installation push block 13 is provided on the outer side of the blue card 3. Through the cooperation of the limiting flange 19 and the mating installation hole 18, the ferrule 17 is limited in and out.

[0033] The working principle of this utility model is as follows: When using this connector, the fiber core of the corresponding specification optical fiber bus is inserted into the through hole of the ferrule 17. UV glue is used in conjunction with a curing lamp for rapid curing. Since the housing 1 is made of transparent material, it has good light transmittance. With the help of a multi-dimensional curing lamp (patent pending in another case), rapid curing connection of the optical fiber can be achieved. The wires on both sides of the optical fiber bus correspond to the wire contact ends 14 on copper sheet 11 and copper sheet 2, respectively. The rotating connection end 10 of the pressure cover 2 is connected to the housing 1. The upper part of the rotating flange 5 is provided with an installation guide slope 6 to facilitate the rotating flange connection. After installation, press down on the end of the cover 2. The cover 2 rotates relative to the flange 5. During the downward rotation, the wire stripping fixing teeth 15 on the inner top wall of the cover 2 cooperate with the wire contact end 14, crushing and destroying the wire protective layer on the wire contact end 14, so that the metal core inside the wire can effectively contact the wire contact end 14 to form a passage. There is no need to use tools to remove the wire insulation, which effectively improves the connection efficiency. The locking slot 8 on the cover 2 cooperates with the locking block 7 on the housing 1 to lock the position of the cover 2. Then, the blue card 3 can be installed on the housing 1 from the other end.

[0034] The ceramic ferrule 4 of the connector shown in the accompanying drawings of this application has a specification of 2.5mm. Different specifications of connectors are provided for different optical fiber busbars.

[0035] The copper end of this invention is provided with a wire contact end 14. A wire stripping and fixing tooth 15 is provided at the position on the top inner side of the pressure cover 2 that mates with the wire contact end 14. During the process of flipping and pressing down the pressure cover 2, the protective layer of the wire can be crushed and destroyed through the cooperation of the wire stripping and fixing tooth 15 and the wire contact end 14, allowing the metal core inside the wire to effectively contact the wire contact end 14 and form a passage. This eliminates the need to remove the wire insulation with tools, effectively improving connection efficiency. The housing 1 is made of transparent material with good light transmission, enabling rapid curing under fiber optic ultraviolet lamp irradiation. The mating position between the pressure cover 2 and the housing 1 is provided with a rotating mating flange 5, a rotating mating hole 9, a locking block 7, and a locking groove 8. The installation process of the pressure cover 2 is simple, and the locking stability is good, thereby improving the convenience and stability of the connector.
