Description

Technical Field

[0001] The present invention relates to the technical field of optical fiber connectors, in particular to a plastic optical fiber connector with data transmission function. Background Art

[0002] At present, the optical fiber on the market is mainly divided into two categories according to the installation of the connector: prefabricated connector finished fiber and on-site connector fiber. The connector of the prefabricated connector finished fiber is one-time injection molding in the production and processing link. Due to the standardized process, the performance of the connector part is stable and the optical attenuation is well controlled. However, since the length of this type of fiber cannot be changed, the same interface needs to produce several types of fibers of different lengths, which still cannot properly meet the various installation needs. On-site connector fiber usually does not have a special connector. It just cuts the plastic optical fiber neatly to ensure that the end face of the optical fiber is flat and then directly inserts it into the optical transceiver. There will be a plastic clamp on the optical transceiver. Push the clamp in, the clamp will hold the optical fiber insertion part tightly and expand it into the transceiver hole to achieve a fixing effect. Since the length can be cut at will and the installation operation is simple, this method is more convenient for on-site construction access. Even professionals are not required to complete the access work.

[0003] Patent 1, Chinese patent number CN201410560273.1 discloses a quartz plastic composite optical fiber assembly, identification method and device, wherein the quartz plastic composite optical fiber assembly includes: a quartz optical fiber, a quartz optical fiber connector, at least two plastic optical fibers and plastic optical fiber connectors corresponding to the at least two plastic optical fibers, wherein the plastic optical fiber is laid on the quartz optical fiber. Through the present invention, the problem that the two ends of the connector cannot be visually checked and displayed whether they are normally connected in the related art is solved, thereby achieving the effect of being able to visually check and display whether the two ends of the connector are normally connected.

[0004] Patent 2, Chinese patent number CN201020260777.9 discloses a plastic optical fiber connector, which has a housing with a receiving cavity, wherein the receiving cavity has a socket for receiving and shrinking the plastic optical fiber; a fiber clamping piece received in the receiving cavity, wherein the fiber clamping piece has a shrinking structure adapted to the socket for shrinking and clamping the plastic optical fiber; one side of the fiber clamping piece has an elastic sheet, wherein the elastic sheet and the housing have a mutually matching snap-fit ​​structure, wherein the elastic sheet also has a stopper for preventing the fiber clamping piece from escaping from the receiving cavity, wherein the housing has a limiting structure matched with the stopper; an elastic element is provided at the bottom of the receiving cavity, wherein the elastic element is compressed between the bottom of the receiving cavity and the fiber clamping piece. The plastic optical fiber connector of the utility model can not only firmly hold the optical fiber, but also allow the optical fiber to be easily disengaged when necessary.

[0005] However, there are still problems when using the above patents. Patent 1 belongs to prefabricated joint finished fiber, which ensures the stability of the interface structure, but cannot meet the needs of arbitrary cutting length. Patent 2 belongs to on-site made joint fiber, which can be cut to length at will, but cannot meet the needs of sufficient stability of the interface and stable light attenuation. Summary of the invention

[0006] 1. Technical issues to be resolved

[0007] In view of the shortcomings of the prior art, the present invention provides a plastic optical fiber connection device with data transmission function, which solves the problem that the demand for arbitrary cutting length cannot be met while the interface is sufficiently stable and the light attenuation is stable.

[0008] (II) Technical solution

[0009] To achieve the above purpose, the present invention is implemented through the following technical solutions: a plastic optical fiber connection device with data transmission function, including an optical transceiver, four positioning pins are fixed on the surface of the optical transceiver, two S-type connectors are provided on the surface of the optical transceiver, and the two S-type connectors are interlocked and surrounded on the surface of the optical transceiver, and the S-type connectors are connected with the positioning pins on the optical transceiver through positioning holes, and the S-type connectors include a fixing seat provided on the surface of the optical transceiver, an optical fiber card slot is provided inside the fixing seat, and the optical fiber card slot changes the embedded plastic optical fiber through four degree bends to form an S-like shape.

[0010] Preferably, the edges around the top surface of the optical transceiver are higher than the middle part, and the S-type connector is located in a depression on the surface of the optical transceiver. A cover plate is provided on the surface of the optical transceiver, and the cover plate is snap-connected with the depression on the surface of the optical transceiver.

[0011] Preferably, a bottom plate is fixed to the bottom surface of the optical transceiver, a battery and a GPS module are sequentially arranged inside the optical transceiver, and both the battery and the GPS module are fixedly connected to the bottom surface of the optical transceiver, and the battery and the GPS module are electrically connected.

[0012] Preferably, a plastic tie is embedded in the surface of the optical transceiver, and the plastic tie is gathered on the surface of the optical transceiver, and the plastic tie is slidably connected to the optical transceiver, and the inner wall of the plastic tie is against the surface of the optical transceiver.

[0013] Preferably, the S-type connector includes a fixing seat arranged on the surface of the optical transceiver, a fiber optic card slot is provided inside the fixing seat, and the shape of the fiber optic card slot is similar to the S shape, and a positioning hole is provided on the surface of the fixing seat, and the positioning hole is a blind hole.

[0014] Preferably, the optical transceiver comprises a shell abutting against the bottom surface of the S-shaped connector, an LED transceiver is fixed on the top surface of the shell, and the LED transceiver is electrically connected to the battery.

[0015] Working principle: The S-type interface contains a fiber optic card slot for embedding plastic optical fiber. Taking advantage of the fact that plastic optical fiber can be bent, the fiber optic card slot changes the embedded plastic optical fiber through four 90-degree bends in the S-type interface to form an "S"-like shape. On the one hand, such a structure helps to ensure that the plastic optical fiber is in the interface and will not be pulled out. On the other hand, since the port of the plastic optical fiber is in the same direction as the fiber entrance, when external force pulls the plastic optical fiber, the fiber port will not be pulled away from the contact point of the optical transceiver together with the S-type interface. The interface contains two positioning holes, which can ensure that the interface is accurately positioned on the optical transceiver. When fixed, the two S-type interfaces are buckled together and embrace the LED transceiver to form a stable structure, which is not easily affected by various external factors and causes relative displacement between the S-type interface and the LED transceiver. The two S-type interfaces are fixed on the corresponding positioning pins through the positioning holes respectively, ensuring their own accurate positioning. The optical transceiver is provided with an opening design, which allows a plastic tie to pass through the inside of the transceiver and bundle the two S-type interfaces with the transceiver together. On the one hand, this design adds an external stable structure, and on the other hand, the plastic tie can be used as an "anti-dismantling" safety buckle. Therefore, this through-opening design can also be used for "lead sealing".

[0016] (III) Beneficial effects

[0017] The present invention provides a plastic optical fiber connection device with data transmission function, which has the following beneficial effects:

[0018] 1. The present invention utilizes the characteristic of plastic optical fiber itself that it can be bent at a large arc to design a safety joint that is not easy to loosen, adopts an S-shaped structure physical device to lock the plastic optical fiber, and utilizes the characteristic of plastic optical fiber transmitting signals through visible light to design a safety locking structure that can simply identify the lock state. No tools or pre-forming are required, which ensures that the plastic optical fiber can be cut at will and ensures the stability of data transmission.

[0019] 2. The present invention utilizes a GPS module to remotely transmit a status signal of whether the lock is safe to the background, and can periodically send out positioning coordinates and optical transceiver receiving signals when powered on, and uses an optical generator with a battery as the support of the S-shaped plastic optical fiber connector, which not only ensures a relatively stable position, but also provides a data transmission medium, ensuring maximum functional requirements and stability at a very low cost.
