Description

Technical Field

[0001] The utility model relates to the technical field of fiber optic connectors, and particularly relates to an optoelectronic composite fiber optic connector. Background Technique

[0002] Fiber-optic communication, also known as optical fiber communication, refers to a way of transmitting information using light and optical fibers. It belongs to a type of wired communication. After light is modulated, it can carry information. Optical fiber communication has the advantages of large transmission capacity and good confidentiality. Optical fiber communication has become the most important wired communication method today. The information to be transmitted is input into a transmitter at the sending end, the information is superimposed or modulated onto a carrier wave that serves as a carrier for the information signal, and then the modulated carrier wave is transmitted to a remote receiving end through a transmission medium, and the original information is demodulated by the receiver.

[0003] In the field of optical communication technology, devices such as connectors, optical modules, and adapters are usually involved. Among them, a connector is an optical passive device that realizes the connection between optical fibers. It has the functions of actively connecting between optical fiber and optical fiber, optical fiber and active device, optical fiber and other passive devices, and optical fiber and instrument. In the prior art, there are a large number of plug-in optoelectronic circuits in devices represented by 5G base stations. Due to the separate setting of optoelectronics, the number of connectors is large and they are divided into two categories of optoelectronics, which need to be paired correctly one by one, resulting in cumbersome operations during installation and maintenance, and it is easy to have plug-in errors. Content of the Utility Model

[0004] To solve the technical problems in the background technique, the utility model proposes an optoelectronic composite fiber optic connector.

[0005] The technical solution adopted by the utility model to solve its technical problems is as follows:

[0006] An optoelectronic composite fiber optic connector includes a housing and a connector body inserted into the housing.

[0007] A pre-buried fiber component is arranged at the output end of the connector body, a fiber guiding seat is clamped at the input end of the connector body, a fiber guiding channel for inserting an external connecting fiber is formed on the fiber guiding seat, and a conductive sheet is arranged on the connector body. One end of the conductive sheet forms a conductive part, and the other end has a power connection part bent upward. The power connection part is placed in the fiber guiding seat, and a limiting channel is formed between the power connection parts. The limiting channel is arranged opposite to the fiber guiding channel.

[0008] Preferably, the conductive portion is arranged in an arc shape, and a limiting groove is formed on the housing for the conductive portion to extend out. Through the above improvement, the conductive portion is arranged in an arc shape, which makes it more convenient to connect the connector to an external communication terminal device, and the limiting groove limits the conductive portion to prevent it from shifting during use.

[0009] Preferably, the connector body is provided with a positioning protrusion, and the conductive sheet is provided with a positioning groove for the positioning protrusion to be placed in. Through the above improvements, during the installation of the conductive sheet, the positioning protrusion on the connector body will be placed in the positioning groove, thereby ensuring the reliability of the installation of the conductive sheet.

[0010] Preferably, a conductive groove is formed on the power connection portion, and a placement groove is formed on the connector body. The conductive groove and placement groove are arranged opposite each other, and both are arranged on either side of the limiting channel. With the above improvement, when the conductive wire of the optoelectronic hybrid cable is inserted into the conductive groove, the power connection portion cuts through the conductive wire surface to establish an electrical connection with the conductive wire, and the excess conductive wire can be placed in the placement groove, making the interior of the connector body more concise.

[0011] Preferably, the bottom of the fiber guide seat is formed with an insertion groove for the positioning protrusion to be placed in, and the two ends of the conductive sheet respectively abut the connector body and the fiber guide seat.

Through the above improvement, the engaging protrusions cooperate with the engaging grooves to engage the fiber guide seat with the connector body, thereby ensuring the stability of the fiber guide seat installation.

[0013] Preferably, the pre-embedded fiber assembly includes a connector, a fiber-embedded body, and a pre-embedded fiber disposed within the fiber-embedded body. A connection channel is formed within the fiber-embedded body for connecting the pre-embedded fiber to an external connecting fiber. The fiber guide seat is formed with a connection hole, the fiber-embedded body is inserted into the connection hole, and the connection channel is disposed opposite the fiber guide channel. With the above improvements, the pre-embedded fiber is already embedded within the fiber-embedded body, and an external optical fiber can pass through the fiber guide channel and enter the connection channel, thereby achieving a quick connection with the pre-embedded fiber.

[0014] Preferably, a tension block is slidably mounted on the fiber embedding body, and the fiber embedding body has a tendency to collapse along the insertion direction. The tension block slides along the fiber embedding body to compress or release the connecting fiber. With this improvement, after the external optical fiber is connected to the pre-embedded optical fiber, the tension block can be slid to squeeze the connection channel, thereby securing the external optical fiber and ensuring the reliability of the optical fiber connection.

An insertion channel is formed on the wire clamping convex part, and extrusion bumps are formed on the first wire inlet convex part and the second wire inlet convex part. The extrusion bumps are placed in the insertion channel. Through the above improvement, when the optical and electrical hybrid cable is placed on the second wire inlet convex part, after the optical and electrical connection is completed, the rotary cover can be rotated to clamp the optical and electrical hybrid cable by the first wire inlet convex part and the second wire inlet convex part respectively, so that the optical and electrical hybrid cable is placed in the insertion channel, and the extrusion bumps will extrude the optical and electrical hybrid cable, thereby ensuring the reliability of fixing the optical and electrical hybrid cable.

[0016] Preferably, a locking cover for closing the first wire inlet convex part and the second wire inlet convex part is rotatably provided on the connector body, and thread convex parts for threaded connection with the locking cover are formed on the outer peripheries of the first wire inlet convex part and the second wire inlet convex part.
