Description

Technical Field

[0001] This utility model relates to the field of optoelectronic communication technology, and in particular to an interface protective cover and optoelectronic conversion device for an optoelectronic converter. Background Technology

[0002] An optoelectronic converter, also known as an Ethernet transceiver or fiber optic transceiver, is an Ethernet transmission media conversion unit that converts short-distance twisted-pair electrical signals to long-distance optical signals.

[0003] A photoelectric converter typically includes modules such as a circuit board, chip, fiber optic interface, and power management module. Structurally, it mainly consists of a rear-end main body and a front-end fiber optic interface. The rear-end main body integrates various electronic components and is generally soldered onto the circuit board; the front-end fiber optic interface extends to the outer edge of the circuit board. During use, a fiber optic patch cord is connected to the front-end fiber optic interface of the photoelectric converter. Repeated insertion and removal of the fiber optic cable, as well as incorrect insertion and removal, can easily cause the front-end fiber optic interface to break at its root, with the break perpendicular to the circuit board. A broken fiber optic interface directly renders the fiber optic converter inoperable, and repairs are time-consuming and labor-intensive. Furthermore, the front-end fiber optic interface of the photoelectric converter is generally directly exposed to the outside, making it susceptible to external electromagnetic interference during operation, affecting the transmission of fiber optic signals. Utility Model Content

[0004] The purpose of this invention is to provide an interface protection cover and a photoelectric conversion device for a photoelectric converter, which can solve the problems of easy breakage of the optical fiber interface of the photoelectric converter in the prior art, and the influence of external electromagnetic signals on the transmission of optical fiber signals.

[0005] To solve the above-mentioned technical problems, this utility model provides an interface protection cover for a photoelectric converter, including a body and a connecting component. The body has a hollow cavity with openings at both ends along its axial direction. The shape of the cavity matches the shape of the front-end optical fiber interface of the photoelectric converter. The cavity is used to accommodate at least a portion of the front-end optical fiber interface. One end of the connecting component is connected to the body, and the other end of the connecting component is used to connect to the rear-end main body of the photoelectric converter.

[0006] Furthermore, the body of the protective cover is interference-fitted with the front fiber optic interface of the photoelectric converter through the cavity.

[0007] Furthermore, the connecting component includes an inverted U-shaped connecting buckle, the shape of which matches the shape of the rear body of the photoelectric converter. One end of the connecting buckle is connected to the first end face of the body. The connecting buckle is used to engage with the rear body of the photoelectric converter and is interference-fitted with the rear body.

[0008] Furthermore, the connecting fastener includes a first connecting boss, a second connecting boss, and a third connecting boss. One end of each of the first connecting boss, the second connecting boss, and the third connecting boss is connected to the first end face of the body, and the other end extends along the axial direction of the body. The three connecting bosses enclose each other to form the connecting fastener. Moreover, the projection of the connecting fastener on the first end face of the body is an inverted U-shape, and the opening of the cavity of the body on the first end face is located within the inverted U-shape.

[0009] Furthermore, the connecting assembly also includes a limiting member, one end of which is connected to the first end face of the body, and the other end extends along the axial direction of the body. There is a gap between the limiting member and the connecting fastener, and the limiting member and the connecting fastener cooperate to fix the circuit board of the photoelectric converter in the gap.

[0010] Furthermore, the limiting member is a T-shaped boss, the horizontal side of which is connected to the first end face of the body, and the vertical side of which extends along the axial direction of the body.

[0011] Furthermore, the axial length of the body is less than the axial length of the front-end fiber optic interface; the interface protective cover also includes at least one front-end limiting boss, one end of the front-end limiting boss is connected to the second end face of the body, and the other end of the front-end limiting boss extends along the axial direction of the body and bends towards the axis of the body to form a limiting surface, which is used to contact the end face of the front-end fiber optic interface and restrict the front-end fiber optic interface from moving along the axial direction of the body.

[0012] Furthermore, the difference between the axial length of the body and the axial length of the front fiber optic interface is within a preset range. At least one front limiting part is provided on the second end face of the body. The front limiting part extends parallel to the second end face, with one end connected to the second end face and the other end located within the opening range of the cavity on the second end face of the body. The front limiting part is used to contact the end face of the front fiber optic interface and restrict the front fiber optic interface from moving along the axial direction of the body.

[0013] Furthermore, the main body and the connecting component are integrally formed.

[0014] This utility model also provides a photoelectric conversion device, including a photoelectric converter and the aforementioned interface protective cover. The photoelectric converter includes a rear main body, a front fiber optic interface, and a circuit board. The rear main body is soldered onto the circuit board, and the front fiber optic interface extends out of the circuit board. The body of the interface protective cover accommodates at least a portion of the front fiber optic interface near the circuit board, and the connecting component of the interface protective cover is connected to the rear main body.

[0015] In summary, compared with the prior art, the interface protection cover and photoelectric conversion device of the photoelectric converter provided by this utility model have the following advantages:

[0016] This invention protects the root of the front-end fiber optic interface with a protective cover. On the one hand, it supports the suspended front-end fiber optic interface, preventing repeated vertical external forces from causing the root of the interface to break. On the other hand, it shields the signal from the fiber optic interface, reducing signal leakage and interference from external electromagnetic signals. Furthermore, the protective cover itself acts as an additional insulating layer, providing insulation and isolation between the front-end fiber optic interface and other electronic components in the circuit.

[0017] In addition, in the structure of this utility model, the protective cover is fixed to the various components and circuit boards of the photoelectric converter by interference fit, which does not require additional fasteners for fixation. The parts are simple and the assembly is straightforward. Attached Figure Description

Detailed Implementation

[0026] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a further detailed explanation of the interface protection cover and photoelectric conversion device for a photoelectric converter according to this utility model. The advantages and features of this utility model will become clearer from the following description.

[0027] It should be noted that the accompanying drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clearly illustrate the purpose of the embodiments of this utility model. Please refer to the accompanying drawings to make the purpose, features, and advantages of this utility model more apparent and understandable. It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are only used to complement the content disclosed in the specification, for those skilled in the art to understand and read, and are not intended to limit the implementation conditions of this utility model. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to the size, without affecting the effects and purposes achieved by this utility model, should still fall within the scope of the technical content disclosed in this utility model.

[0028] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0029] In this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0030] like Figure 1 , Figures 5 to 7 The diagram shows a schematic of a photoelectric converter. The photoelectric converter 2 generally includes a front-end fiber optic interface 21, a rear-end main body 22, and a circuit board 3. Various electronic components are integrated within the rear-end main body 22 and soldered onto the circuit board 3. These electronic components are protected by the outer casing of the rear-end main body 22, which is also soldered onto the circuit board 3. The front-end fiber optic interface 21 extends out of the circuit board 3 and is suspended in mid-air. Several outer walls 202, 203, 204, 208, and 209 of the front-end fiber optic interface 21 are unsupported and unfixed. During use, the fiber optic patch cord is connected to the front-end fiber optic interface 21. Incorrect and repeated insertion and removal can cause the outer wall of the front-end fiber optic interface 21 to be subjected to an external force perpendicular to the circuit board 3. Prolonged excessive external force on the outer wall of the front-end fiber optic interface 21 can cause it to break at its root (the connection point with the rear-end main body 22). On the other hand, the outer wall of the front-end fiber optic interface 21 is in direct contact with the outside world and is in a state without signal protection. The photoelectric signal will leak out at the front-end fiber optic interface 21, which is not conducive to signal transmission. Moreover, the leaked signal will also cause electromagnetic interference to other electronic devices. In addition, external electromagnetic interference signals will also interfere with the signal transmitted by the fiber optic at the front-end fiber optic interface 21, which is not conducive to signal transmission.

[0031] Based on this, the purpose of this utility model is to provide an interface protection cover and a photoelectric conversion device for a photoelectric converter, so as to solve the problems of easy breakage of the optical fiber interface of the photoelectric converter in the prior art and the influence of external electromagnetic signals on the transmission of optical fiber signals.

[0032] To achieve the above idea, such as Figures 1 to 7 As shown, this utility model provides an interface protection cover 1 for a photoelectric converter, including a body 11 and a connecting component 12. The body 11 has a hollow cavity with openings at both ends along its axial direction. The shape of the cavity matches the shape of the front-end optical fiber interface 21 of the photoelectric converter. The cavity is used to accommodate at least a portion of the front-end optical fiber interface 21. One end of the connecting component 12 is connected to the body 11, and the other end of the connecting component 12 is used to connect to the rear-end main body 22 of the photoelectric converter.

[0033] In this invention, by setting a protective cover, the front-end fiber optic interface 21 can be wrapped and protected. On the one hand, it can support the suspended front-end fiber optic interface 21, preventing the root of the front-end fiber optic interface 21 from breaking due to repeated vertical external forces acting on it. On the other hand, it can also shield the front-end fiber optic interface 21, reducing the leakage of fiber optic transmission signals and reducing the interference of external electromagnetic signals on the fiber optic transmission signals. In addition, the presence of the protective cover body 11 is equivalent to adding an insulating layer, which plays an insulating and isolation role, isolating the front-end fiber optic interface 21 from other electronic components in the circuit.

[0034] Preferably, the body 11 of the protective cover 1 is interference-fitted with the front-end fiber optic interface 21 of the photoelectric converter through the cavity. Specifically, the four surfaces 103, 105, 110 and 111 of the hollow cavity of the protective cover body 11 can be interference-fitted with the four surfaces 202, 204, 208 and 209 of the front-end fiber optic interface 21, respectively.

[0035] In one implementation of this utility model, the connecting component 12 includes an inverted U-shaped connecting fastener 13. The shape of the connecting fastener 13 matches the shape of the rear body portion 22 of the photoelectric converter. One end of the connecting fastener 13 is connected to the first end face of the body 11. The connecting fastener 13 is used to engage with the rear body portion 22 of the photoelectric converter and is connected to the rear body portion 22 with an interference fit. The connecting fastener 13 achieves a more reliable connection between the protective cover and the photoelectric converter, and works with the protective cover body 11 to effectively support and protect the root of the front fiber optic interface 21.

[0036] Furthermore, the connecting fastener 13 includes a first connecting boss 131, a second connecting boss 132, and a third connecting boss 133. One end of each of the first connecting boss 131, the second connecting boss 132, and the third connecting boss 133 is connected to the first end face of the body 11, and the other end extends along the axial direction of the body 11. The three connecting bosses enclose to form the connecting fastener 13, and the projection of the connecting fastener 13 onto the first end face of the body 11 is an inverted U-shape. The opening of the cavity of the body 11 on the first end face is located within the inverted U-shape. Figure 2 and Figure 3As shown, the three connecting bosses can be cuboid bosses, and the three cuboid bosses enclose to form an inverted U-shaped connecting fastener 13. The three inner wall surfaces 102, 104, and 108 of the inverted U-shape will be interference-fitted with the three outer walls 206, 205, and 207 of the rear main body 22 of the photoelectric converter, respectively. Furthermore, the inverted U-shaped surfaces 101 and 106 can also contact the upper surface 301 of the circuit board 3. Moreover, since the opening of the first end face is located within the inverted U-shaped structure, a limiting surface will also be formed between the connecting fastener 13 and the opening, such as... Figure 2 and Figure 3 As shown, face 109 will abut against the end face 201 of the rear main body 22, so that the body 11 of the protective cover can just contact the end face of the rear main body 22, so that the body 11 just covers the root of the front fiber optic interface 21, and can also prevent the body 11 of the protective cover from moving further towards the circuit board.

[0037] Furthermore, the connecting assembly 12 also includes a limiting member 14. One end of the limiting member 14 is connected to the first end face of the body 11, and the other end extends along the axial direction of the body 11. A gap exists between the limiting member 14 and the connecting latch 13. The limiting member 14 and the connecting latch 13 cooperate to fix the circuit board 3 of the photoelectric converter in the gap. When the connecting latch 13 is connected to the rear main body 22, the circuit board 3 can be inserted into the gap. The limiting member 14 and the connecting latch 13 are located on opposite sides of the circuit board 3. That is, the limiting member 14 contacts the lower surface 302 of the circuit board 3, and the surfaces 101 and 106 of the connecting latch 13 contact the upper surface 301 of the circuit board 3. This restricts the movement of the protective cover in a direction perpendicular to the circuit board. Preferably, the limiting member 14 can be a T-shaped boss, the horizontal side of which is connected to the first end face of the body 11, and the vertical side of which extends along the axial direction of the body 11.

[0038] Furthermore, the axial length of the body 11 is less than the axial length of the front-end fiber optic interface 21. That is, the body 11 of the protective cover only covers a portion of the front-end fiber optic interface 21 near its root, with its front end exposed. To restrict the axial movement of the front-end fiber optic interface 21, the interface protective cover also includes at least one front-end limiting protrusion 15. One end of the front-end limiting protrusion 15 is connected to the second end face of the body 11, and the other end of the front-end limiting protrusion 15 extends axially along the body 11 and bends towards the axis of the body 11 to form a limiting surface 112. The limiting surface 112 contacts the end face of the front-end fiber optic interface 21 and restricts the front-end fiber optic interface 21 from moving axially along the body 11. Simultaneously, the surface 109 of the connecting clip abuts against the end face 201 of the rear main body 22, allowing both ends of the protective cover body 11 to be fixed, thus restricting the axial movement of the front-end fiber optic interface 21 along the body. The number of front-end limiting protrusions 15 can be multiple, and the structures of multiple front-end limiting protrusions 15 can be set differently, with one or two having a limiting surface 112, and the others not having a limiting surface, only providing support for the front-end fiber optic interface 21.

[0039] In another implementation of this utility model, the difference between the axial length of the body 11 and the axial length of the front-end fiber optic interface 21 is within a preset range, that is, the lengths of the two are basically the same. At this time, the body 11 completely covers the front-end fiber optic interface 21. At this time, at least one front-end limiting part (not shown in the figure) can be provided on the second end face of the body 11. The front-end limiting part extends parallel to the second end face, with one end connected to the second end face and the other end located within the opening range of the cavity on the second end face of the body. The front-end limiting part is used to contact the end face of the front-end fiber optic interface 21 and restrict the front-end fiber optic interface from moving along the axial direction of the body. When the body 11 just covers the front-end fiber optic interface 21, the limiting part can be directly set in the opening to restrict the front-end fiber optic interface 21 from moving along the axial direction of the body.

[0040] Preferably, in the present invention, the body 11 and the connecting component 12 are integrally formed, that is, the protective cover 1 is integrally formed. The material of the protective cover 1 is preferably polyoxymethylene. After integral forming, the structure has high strength, high toughness, high dimensional accuracy and high hardness.

[0041] This utility model also provides a photoelectric conversion device, including a photoelectric converter and the aforementioned interface protection cover. The photoelectric converter includes a rear main body 22, a front fiber optic interface 21, and a circuit board 3. The rear main body 22 is soldered onto the circuit board 3. The front fiber optic interface 21 extends out of the circuit board 3. The body 11 of the interface protection cover 1 accommodates at least a portion of the front fiber optic interface 21 near the circuit board 3. The connecting component 12 of the interface protection cover 1 is connected to the rear main body 22.

[0042] In summary, compared with the prior art, the interface protection cover and photoelectric conversion device of the photoelectric converter provided by this utility model have the following advantages:

[0043] This invention protects the root of the front-end fiber optic interface 21 with a protective cover. On the one hand, it supports the suspended front-end fiber optic interface 21, preventing repeated vertical external forces from breaking the root of the front-end fiber optic interface 21. On the other hand, it shields the front-end fiber optic interface 21, reducing signal leakage and interference from external electromagnetic signals. Furthermore, the protective cover body 11 acts as an additional insulating layer, providing insulation and isolation between the front-end fiber optic interface 21 and other electronic components in the circuit.

[0044] In addition, in the structure of this utility model, the protective cover is fixed to the various components and circuit boards of the photoelectric converter by interference fit, which does not require additional fasteners for fixation. The parts are simple and the assembly is straightforward.

Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims. Obviously, those skilled in the art can make various modifications and variations to the utility model without departing from its spirit and scope. Therefore, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
