Description

A POF connector with power supply Technical Field

[0001] The present invention relates to the technical field of connectors, in particular to a POF connector with power supply. Background Art

[0002] With the continuous development of fiber optic communication technology, the requirements for supporting fiber optic cables and fiber optic connectors are becoming higher and higher.

[0003] Plastic Optical Fiber (POF) is a type of optical fiber (optical fiber) made of a highly transparent polymer core material, such as polystyrene (PS), polymethyl methacrylate (PMMA), or polycarbonate (PC), and a sheath material, such as PMMA or fluoroplastics. As an alternative to quartz fiber, POF offers a low-cost, lightweight, and easy-to-install data transmission medium. It is particularly well-suited for short-distance, small- to medium-capacity systems (such as access networks) that utilize numerous connectors. Compared with multimode quartz optical fiber, plastic optical fiber is softer, has good mechanical flexibility, is dust-resistant, and is easy to install and maintain. Of particular importance is that the core diameter of POF is usually 0.5mm or larger, while the core diameter of multimode quartz optical fiber is 62.5 microns or 50 microns. POF, which has a core diameter about 10 times larger, is easy to connect and align. For step-index POF with a core diameter of 980 microns and gradient-index POF with a core diameter of 500 microns, even a ±30 micron offset in the connection does not seriously affect the coupling loss (increasing the loss by approximately 0.03dB), allowing the use of inexpensive injection-molded connectors, thereby significantly reducing the total cost of the system. Plastic optical fiber is widely used in civilian fields such as electricity, medical care, and automobiles. Technical issues

[0043] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0044] As shown in FIG. 17 , a POF connector is shown, which includes a POF female connector 100 and a POF male connector 200 that plugs into the POF female connector 200 .

[0045] 1-9 , the POF female connector 100 with power supply is mounted on the PCB board 4 and is used to transmit optical signals to the optical fiber chip 41 mounted on the PCB board 4 , and the optical fiber chip 41 receives the optical signals.

[0046] The POF female connector 100 includes an insulating seat 1 , a lens module 300 , and two electrode terminals 16 .

[0047] In which, the insulating seat 1 has a mating slot 12 for mating with a POF male connector and a power slot 15 located next to the mating slot 12 and connected to the mating slot 12. The bottom of the insulating seat 1 is provided with a mounting position 11 connected to the mating slot 12; two electrode terminals 16 are fixed in the insulating seat 1, the upper ends of the electrode terminals 16 are exposed in the power slot 15, and form a power socket with the power slot 15, and the lower ends of the electrode terminals 16 extend out of the lower end surface of the insulating seat 1; the lens module 300 is installed in the mounting position 11; the lens module 300 includes a plastic optical fiber lens 2, the input end 221 of the lens body 22 of the plastic optical fiber lens 2 is exposed in the mating slot 12, and the output end 222 of the lens body 22 is exposed at the lower end of the insulating seat 1; the insulating seat 1 is installed on the PCB board 4, and the output end 222 of the lens body 22 is docked with the optical fiber chip 41 installed on the PCB board 4. That is to say, the POF female connector 100 in the present invention does not carry the optical fiber chip 41, and does not require an additional structure to fix the optical fiber chip. Its structure is relatively simple. It only connects with the optical fiber chip 41 through the lens body 22 in the plastic optical fiber lens 2, and transmits the optical signal to the optical fiber chip 41. Finally, the optical signal is received by the optical fiber chip 41. The present invention is particularly suitable for use in scenarios where the optical fiber chip has been soldered and fixed on the PCB board and only needs to transmit the optical signal. In addition, the power socket formed by the electrode terminal 16 and the power slot 15 of the POF female connector 100 in the present invention can be used for connecting with the power plug to achieve the power conduction function, that is, the present invention can realize optical signal transmission and power transmission at the same time, meeting the use scenarios that require power conduction and optical signal transmission, so as to meet different use requirements, without the need to add an additional set of independent power plugs and power sockets, which can simplify the product structure and make it more convenient to use.

[0048] The insulating seat 1 is provided with a mounting flange 18 on its periphery, a groove body is provided on the mounting flange 18, and an O-ring 17 is provided in the groove body. When in use, the insulating seat 1 is passed through the mounting hole of the casing, and the O-ring 17 contacts the surface of the casing to achieve a sealed assembly.

[0049] The lens module 300 also includes a bracket 3, in which the plastic optical fiber lens 2 is fixed. The bracket 3 has an undercut 31 on its outer side, and a retaining hole 111 on the inner wall of the mounting position 11. The undercut 31 engages with the retaining hole 111 and can move up and down relative to the retaining hole 111. A metal spring 32 is also provided between the bracket 3 and the mounting position 11. The metal spring 32 elastically supports the bracket 3 relative to the insulating seat 1, allowing the bracket 3 to be fixed to the mounting position 11 in an elastically floating manner. In other words, the bracket 3 and the plastic optical fiber lens 2 fixed thereto can elastically float relative to the insulating seat 1. In actual use, after the POF female connector 100 of the present invention is fixedly mounted on a PCB board, elastic contact is formed between the plastic optical fiber lens 2 and the optical fiber chip 41 on the PCB board 4, thereby avoiding the formation of a gap between the two. This ensures the optical signal transmission quality of the plastic optical fiber lens 2 and prevents rigid contact that could damage the plastic optical fiber lens or optical fiber chip, thereby ensuring the product's service life and quality.

[0050] The specific assembly structure of the bracket 3 and the plastic optical fiber lens 2 is as follows:

[0051] The bracket 3 has a mounting groove 33 at its lower end and a docking window 34 extending through the mounting groove 33 at its upper end. The plastic fiber lens 2 is mounted in the mounting groove 33, with the input end 221 of the plastic fiber lens 2 exposed in the docking window 34 and in the docking slot 12, while the output end 222 of the plastic fiber lens 2 is exposed. A non-circular positioning buckle 331 is also provided within the mounting groove 33. The plastic fiber lens 2 has a second positioning hole 201 extending therethrough, and the positioning buckle 331 passes through the second positioning hole 201 to engage with the plastic fiber lens 2 for positioning, thereby ensuring that the plastic fiber lens 2 is stably mounted within the mounting groove 33. To further enhance the stability of the assembly structure, a plurality of pressing protrusions 332 are formed within the mounting groove 33. The pressing protrusions 332 abut against the periphery of the plastic fiber lens 2 to constrain the plastic fiber lens 2, thereby enhancing the stability of the assembly structure.

[0052] The metal spring piece 32 is embedded in the limiting groove 35 provided at the upper end of the bracket 3. The metal spring piece 32 is formed with multiple elastic force arms 321 protruding upward. The elastic force arms 321 are all in contact with the bottom surface of the mounting position 11, thereby eliminating the gap between the bracket 3 and the mounting position 11, and at the same time can stably elastically support the bracket 3, so that the bracket 3 can achieve elastic floating relative to the insulating seat 1.

[0053] The plastic optical fiber lens 2 includes a base 21 and a lens body 22 integrally fixed to the base 21 . The lens body 22 has an input end 221 and an output end 222 . The input end 221 and the output end 222 are correspondingly distributed.

[0054] The lower end surface of the bracket 3 is further provided with a recess 36 for accommodating the optical fiber chip 41 , and the output end 222 of the plastic optical fiber lens 2 is exposed in the recess 36 , thereby achieving a light shielding effect, thereby improving the transmission performance of the optical signal.

[0055] The lower end surface of the insulating seat 1 is formed with a plurality of positioning protrusions 13, which are used to be embedded and fixed with the PCB board. The positioning protrusions 13 are divided into a first positioning post 131 and a second positioning post 132 by a slit 130 opening upward along the bottom surface of the positioning protrusion 13. The lower end of the second positioning post 132 is also formed with a buckle 133 protruding outward. This not only realizes the function of being embedded and fixed with the PCB board, but also prevents the insulating seat 1 from accidentally detaching from the PCB board.

[0056] The four corners of the insulating seat 1 are each provided with a guide groove 14 that passes through the mounting position 11; the four corners of the bracket 3 are each provided with a guide block 37, which is embedded in the guide groove 14 to ensure that the bracket 3 is stably assembled in the mounting position 11 and can play a guiding role.

[0057] In summary, the POF female connector 100 in the present invention does not carry an optical fiber chip 41, and does not require an additional structure to fix the optical fiber chip. Its structure is relatively simple. It only connects to the optical fiber chip 41 through the lens body 22 in the plastic optical fiber lens 2, and transmits the optical signal to the optical fiber chip 41. Finally, the optical signal is received by the optical fiber chip 41. The POF female connector 100 in the present invention is particularly suitable for use in scenarios where the optical fiber chip has been soldered and fixed on the PCB board and only needs to transmit optical signals. In addition, the power socket formed by the electrode terminal 16 and the power slot 15 of the POF female connector 100 in the present invention can be used for connecting with the power plug to achieve the power conduction function, that is, the present invention can realize optical signal transmission and power transmission at the same time, meeting the use scenarios that require power conduction and optical signal transmission, so as to meet different use requirements, without the need to add an additional set of independent power plugs and power sockets, which can simplify the product structure and make it more convenient to use.

That is to say, the POF male connector 200 in the present invention sets the power plug 9 on the outside of the plug-in protrusion 51, so that the POF male connector 200 comes with a power plug 9; when the present invention is in use, the plug-in protrusion 51 and the power plug 9 are simultaneously inserted into the plug-in slot 12 and the power slot 15 of the POF female connector 100, wherein the optical fiber line 7 corresponds to the input end 221 of the lens body 22, and the power plug 9 is inserted into the power slot 15, and the power terminal 92 is connected to the electrode terminal 16, thereby realizing optical signal transmission and power transmission at the same time, meeting the use scenarios that require power conduction and optical signal transmission, to meet different use requirements, without the need to add an additional set of independent power plugs and power sockets, which can simplify the product structure and make it more convenient to use.

[0060] The power plug 9 and the plug-in protrusion 51 are detachable structures, that is, when the power conduction function is not needed, the power plug 9 can be removed from the plug-in protrusion 51, which is extremely convenient to use.

[0061] The assembly structure of the power plug 9 and the plug-in protrusion 51 is as follows: a guide groove 911 with a T-shaped cross-section is provided on the outside of the plastic shell 91, and a first positioning groove 912 is provided at the rear end of the guide groove 911; an anti-derailment anti-derailment 513 with a T-shaped cross-section is integrally formed on the outside of the plug-in protrusion 51, and a first positioning buckle 514 is provided at the rear end of the anti-derailment anti-derailment 513. The plastic shell 91 is sleeved on the anti-derailment anti-derailment 513 through the guide groove 911, and the first positioning buckle 514 is fastened and fixed with the first positioning groove 912, so that the plastic shell 91 is fixed to the outside of the plug-in protrusion 51. The assembly structure is simple and easy to assemble, and the rear end surface of the plastic shell 91 is also in contact with the front of the insulator 5, thereby ensuring that the power plug 9 will not retreat and ensuring the stability of the assembly structure.

[0062] The plastic shell 91 is provided with a terminal hole 913 that passes through the front and rear ends.
