Technical Field
The present invention relates to a fiber optic patching module, and more particularly, to an EMI shield, a fiber optic patching module having an EMI shield, and a method of assembling a fiber optic patching module.
Background
The optical fiber switching module is a switching module for mutually switching optical signals and electric signals. The associated components of the electrical signals are prone to electromagnetic interference (Electromagnetic Interference, EMI), so that the module is encased in a metal housing in many directions to protect the components from EMI. However, in the direction in which the electrical signal-related component leads to the extension of the optical fiber (i.e., the optical port portion), the metal housing lacks effective protection, so that it is necessary to additionally provide a shield perpendicular to the extension direction of the optical fiber.
The optical port portion of current fiber optic adapter modules employs a shield with through holes. The through hole allows the fiber ferrule (Stub) to pass through, so that the shielding piece can pass through the fiber ferrule from the front end and is sleeved on the periphery of the fiber ferrule. However, the front end of the optical fiber core is often connected with other optical devices, so that the front end of the optical fiber core is huge in size, and the shielding piece is difficult to be sleeved from the front end; if the size of the through hole is to be increased, the shielding piece cannot be effectively matched with the optical fiber ferrule after being sleeved, and the actual EMI protection effect is also greatly reduced.

The objects, features and effects of the present invention will be apparent to those skilled in the art from the disclosure of the present specification. It is to be understood that the invention may be practiced or carried out in other embodiments and that various modifications and alterations may be made in the details of the description herein without departing from the spirit or scope of the invention. The drawings of the present invention are merely schematic illustrations, and are not drawn to actual dimensions. The following embodiments will further illustrate the related art content of the present invention in detail, but the disclosure is not intended to limit the claims of the present invention. The description is as follows:
as shown in fig. 3, the fiber switching module 100 according to the embodiment of the present invention includes: the optical fiber connector comprises a housing 1, an optical interface 2, at least two optical fiber ferrules 3, at least two optical fibers 4, at least two ferrule sleeves 5 and an EMI shield 6.
The housing 1 includes a base 11 and an upper cover 12 for accommodating the rest of the components of the fiber optic adapter module 100, and the base 11 and the upper cover 12 are preferably metal or are coated with metal on the inner surface for EMI protection. The shape of the housing 1 can be changed as desired.
The optical interface 2 is used for converting an optical signal transmitted by the optical fiber 4 into an electrical signal, or converting the electrical signal into an optical signal, and transmitting the optical signal out of the optical fiber 4. In this embodiment, the optical interface 2 includes a transmitting-side optical interface 21 (connectable to a photodiode), a receiving-side optical interface 22 (connectable to a Vertical-Cavity Surface-Emitting Laser (VCSEL)), and a circuit board 23. The transmitting optical interface 21 and the receiving optical interface 22 are respectively connected to the circuit board 23 by signals, and are respectively connected to the optical fibers 4. The circuit board 23 extends rearward and may be signally connected to other external devices to receive or transmit signals.
In fig. 3, a portion of the receptacle rear end 8 is removed to show the Fiber Stub 3. The contents concerning the socket rear end portion 8 will be described later. The optical fiber ferrule 3 has a cylindrical shape, and has a through hole in its axial center for accommodating the optical fiber 4. In this embodiment, the optical fiber ferrule 3 is made of a ceramic material, has good chemical stability, is wear-resistant, and is suitable for precision machining.
One end of the optical fiber 4 is inserted into the optical fiber ferrule 3.
The ferrule sleeve 5 connects the optical fiber ferrules 3 in the axial direction. Referring to fig. 7, the ferrule sleeve 5 may be provided with another fiber ferrule to align the connectorized optical fiber 4.
In fig. 3, a plurality of sets of optical fiber ferrules 3, optical fibers 4 and ferrule sleeves 5 are shown. Preferably, there is at least one group of optical fiber ferrule 3, optical fiber 4 and ferrule sleeve 5 (two in number), and the group of optical fibers 4 are respectively connected to the transmitting end optical interface 21 and the receiving end optical interface 22 to respectively receive optical signals from outside and transmit the optical signals out of the optical fiber switching module 100. In fig. 3, four sets of the above-described configuration are shown, however, the invention is not limited thereto, and the number of sets of components may be varied, and in a most simplified state, there may be only a single fiber ferrule 3, fiber 4, and ferrule sleeve 5 to accommodate the EMI shield 6.
Fig. 1 shows a detailed structure of the EMI shield 6. As shown in fig. 1, the EMI shield 6 includes a metal shield 61, and the metal shield 61 is provided with at least one receiving hole 611. The number of the receiving holes 611 can be adjusted according to the number of the optical fiber ferrules 3/optical fibers 4. The side of the metal shielding body 61 is provided with a guide channel 612, the guide channel 612 is communicated with the accommodating hole 611 from the side of the metal shielding body 61, the width of the guide channel 612 is smaller than the diameter of the accommodating hole 611 and allows the optical fiber 4 to pass through, and the optical fiber inserting core 3 is arranged in the accommodating hole in a penetrating way.
Next, how the EMI shield 6 is assembled will be described. The method for assembling the optical fiber switching module 100 according to the embodiment of the invention comprises the following steps:
as shown in fig. 4 and 8, in step S101, the optical fiber 4 is led into the accommodating hole 611 along the radial direction of the corresponding optical fiber ferrule 3 (as shown by the arrows on both sides in fig. 4) from the guiding channel 612 on the side of the metal shielding body 61. At this time, one end of the optical fiber 4 is fixed to the transmitting optical interface 21 or the receiving optical interface 22 in advance, and the other end is connected to the optical fiber receptacle 7 or the receptacle hook 9 (the functions of the optical fiber receptacle 7 and the receptacle hook 9 will be described later), so that the EMI shield 6 is difficult to be inserted from both ends of the optical fiber 4. However, the metal shield 61 is easily inserted from the side (radial direction) of the optical fiber 4 by providing the guide channel 612 and the receiving hole 611 communicating with the guide channel 612 in the metal shield 61.
Next, as shown in fig. 4 and 8, in step S102, the metal shield 61 is moved relatively in the axial direction of the optical fiber ferrule 3, and the optical fiber ferrule 3 with the receptacle rear end portion 8 is accommodated in the accommodation hole 611.
Therefore, the EMI shield 6 of the present invention can be inserted into the fiber ferrule 3 and the peripheral socket rear end 8 thereof from the side of the optical fiber 4, so that the EMI shield 6 can be directly installed into the fiber socket 7, not only improving the assembly structure of the fiber optic adapter module 100, but also facilitating the installation of the EMI shield 6 and achieving effective and high coverage EMI shielding performance.
In this embodiment, as shown in FIG. 1, one EMI shield 6 has four receiving holes 611 to mate two sets of optical fibers 4/fiber ferrules 3. However, the present invention is not limited thereto, and one EMI shield 6 may have only two receiving holes 611 to match a group of optical fibers 4/optical fiber ferrules 3, or in the simplest state, one EMI shield 6 may have only a single receiving hole 611 for mounting a single optical fiber 4/optical fiber ferrule 3.
In the present embodiment, the number of the accommodating holes 611 and the guide channels 612 are in a one-to-one relationship, each accommodating hole 611 has its corresponding guide channel 612, and when the number of the accommodating holes 611 and the guide channels 612 is two or four, the two or four guide channels 612 correspond to the two or four accommodating holes 611, respectively. The guiding channel 612 is preferably arranged at the side closest to the accommodating hole 611.
However, the present invention is not limited thereto, and in another embodiment, as shown in fig. 2, in the metal shield 61 of the EMI shield 6a, a sub-guide passage 613 is further provided between each two receiving holes 611, and the sub-guide passage 613 communicates with the two receiving holes 611. Thus, every two receiving holes 611 may share one guide passage 612. Two optical fibers 4 enter the first accommodating hole 611 through the guide channel 612, and one optical fiber 4 enters the second accommodating hole 611 through the auxiliary guide channel 613. Based on a similar concept, the EMI shield may also be configured such that one guide channel 612 connected to the side is shared between a plurality (e.g., four, six, eight) of receiving holes 611, and the plurality of receiving holes 611 communicate with the sub-guide channel 613 to allow the optical fibers to be respectively moved into each of the receiving holes 611. In the embodiment of fig. 1, the guide channels 612 are formed on the left and right sides of the metal shielding body 61; in the embodiment of fig. 2, the guide channel 612 is formed on the lower side of the metal shield 61. However, the present invention is not limited thereto, and the side position of the opening guide 612 may be simply changed as needed.
Further, as shown in fig. 1, the EMI shield 6 further includes at least one set of snap blocks 62 respectively disposed on opposite sides of the metal shield 61. The primary purpose of the snap-lock block 62 is to snap-lock to other optical devices to securely hold the EMI shield 6 in place with the fiber stub 3. Therefore, the setting position of the fastening block 62 needs to be matched with the design of other optical devices, and the setting position of the guiding channel 612 avoids the setting position of the fastening block 62. For example, the fastening blocks 62 in fig. 1 are disposed on the upper and lower sides of the metal shielding body 61, and the guiding channels 612 are disposed on the left and right sides; the fastening blocks 62 in fig. 2 are disposed on the left and right sides of the metal shielding body 61, and the guiding channels 612 are opened on the lower Fang Cebian (alternatively, the upper side or the upper and lower sides may be used).
Further, as shown in fig. 1 and 2, the fastening block 62 includes an elastic arm 621 extending from a side of the metal shield 61, and a fastening portion 622 located at an end of the elastic arm 621. The elastic arm 621 is curved, has the function of storing elastic potential energy, can maintain the parallel optical axes of the arrays arranged by the optical fiber ferrules 3, avoids deflection caused by assembly tolerance, and can maintain effective contact during switching. The fastening portion 622 is used for fastening to other optical devices, and is in the form of a groove in the present embodiment, however, the present invention is not limited thereto.
Further, as shown in fig. 3-7, the fiber optic patching module 100 also includes a fiber receptacle 7. The number of the optical fiber ferrules 3, the optical fibers 4, the ferrule sleeve 5 and the accommodating holes 611 is at least two, and the optical fiber socket 7 is connected with the two optical fiber ferrules 3 and is used for fixing one group of the optical fiber ferrules 3 and the ferrule sleeve 5 to form an optical fiber array. Fig. 3 and 5 show an optical fiber array formed by a plurality of optical fiber receptacles 7 side by side.
Further, as shown in fig. 3 to 7, the fiber switching module 100 further includes a rear receptacle end 8 disposed at the periphery of the fiber stub 3. The receiving hole 611 matches the outer diameter of the socket rear end 8. The rear receptacle end 8 is preferably made of metal (e.g., iron), and the rear receptacle end 8 is wrapped around most of the optical fiber ferrule 3 and fills the gap between the optical fiber ferrule 3 and the receiving hole 611 to form a continuous shielding surface, thereby further improving EMI protection.
Further, as shown in fig. 3 and 4, the fiber switching module 100 further includes a socket hook 9 connected to the fiber socket 7. The socket hook 9 includes a frame 91 and a hook block 92 extending from the frame 91. The frame 91 is connected to one or more fiber optic receptacles 7, and the engaging portions 622 of the engaging pieces 62 are fixed to the engaging portions 911 on the surface of the frame 91. In this embodiment, the engaging portion 911 is a bump to be engaged with the engaging portion 622 having a groove shape. However, the present invention is not limited thereto, and the fastening portion 622 and the engaging portion 911 may have other shapes, and when the socket hook 9 is not present, the fastening portion 622 may be fastened to the optical fiber socket 7 or other optical devices. The hooking block 92 extends in the axial direction of the optical fiber ferrule 3 and can be used for fixing another optical device having an optical fiber cable to be connected.
Therefore, the method for assembling the fiber optic patching module 100 according to the embodiments of the present invention may further include the following steps: in step S103, the fiber optic receptacle 7 is sleeved into the receptacle hook 9 to complete the assembly.
The present invention has been disclosed in the foregoing in terms of preferred embodiments, however, it will be understood by those skilled in the art that the embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of the present invention.
