Description

Technical Field

[0001] The present invention relates to the technical field of photoelectric conversion, and in particular to an optical module capable of good heat conduction. Background Art

[0002] The optical module is one of the most important devices in current communications. It is mainly composed of optoelectronic devices, functional circuits and optical interfaces. Optoelectronic devices include transmitting and receiving parts. The main function of the optical module is photoelectric conversion. At the same time, it can also integrate many signal processing functions, such as function control, performance energy collection and monitoring. After the optical module is connected to the circuit, it will generate heat in the process of photoelectric conversion. Therefore, in order to ensure the normal use of the optical module, the optical module needs to have a certain thermal conductivity and heat dissipation ability.

[0003] However, existing optical modules still have the following defects in heat conduction and heat dissipation:

[0004] 1. Existing optical modules simply rely on heat conduction plates for heat dissipation. However, in an environment with poor air circulation, the heat conduction plate has poor heat conversion capability and cannot quickly take away heat, which reduces the heat dissipation effect.

[0005] 2. In order to improve the heat dissipation capacity, some existing optical modules have a large number of heat dissipation holes. However, when not plugged in, a large number of heat dissipation holes will cause dust to enter the optical module during placement and transportation, which will cause damage to the optical module, and it is impossible to meet the requirements of dust prevention and heat dissipation at the same time.

[0033] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0034] An optical module capable of good heat conduction according to a preferred embodiment of the present invention will be described in detail below. Figure 1-2 As shown, an optical module with good heat conduction includes a shell 1, the front end of the bottom of the shell 1 extends forward and is fixedly connected to a heat dissipation guide plate 2, heat dissipation windows 3 are opened at the four end faces of the outer periphery of the shell 1, and an optical fiber connection component 4 is provided at the rear end of the shell 1. The optical fiber connection component 4 is used for the stable connection between the optical module and the optical fiber.

[0035] A mounting frame 5 is fixedly installed above the heat dissipation guide plate 2 at the front end of the shell 1, and a photoelectric conversion component is arranged inside the mounting frame 5. A heat dissipation component 6 is arranged on the top of the mounting frame 5. The heat dissipation component 6 can improve the thermal conductivity of the optical module when it is in use while ensuring the sealing of the optical module when it is not in use. An electrical connection component 7 is arranged on the front side of the mounting frame 5, and the electrical connection component 7 connects the optical module with the circuit.

[0036] When in use, the optical module is connected to the optical fiber through the optical fiber connection component 4, and the optical module is connected to the circuit through the electrical connection component 7, thereby completing the installation of the optical module. Through the functions of the heat dissipation guide plate 2, the heat dissipation window 3 and the heat dissipation component 6, the optical module can be effectively heat-conducted and heat-dissipated during use.

[0037] like Figure 2-3As shown, the optical fiber connection component 4 includes a column 41, the rear end of the shell 1 is fixedly installed with the column 41, and a connecting plate 42 is limitedly slidably connected between the columns 41, a spring 43 is fixedly connected between the front end of the connecting plate 42 and the rear end of the shell 1, and the spring 43 is wrapped around the outside of the column 41 to ensure a stable elastic connection of the connecting plate 42, a bellows 44 is fixedly connected between the front end of the connecting plate 42 and the rear end of the shell 1, and the contraction and extension of the bellows 44 ensure that the connecting plate 42 can move elastically, and an optical fiber interface 45 is installed inside the rear side of the connecting plate 42, and the opening of the optical fiber interface 45 faces the rear side to connect with the optical fiber, and the front end of the optical fiber interface 45 is connected to the photoelectric conversion component inside the installation frame 5 through a bent cable, and a ventilation hole 46 is opened on the rear side of the shell 1, and the ventilation hole 46 connects the shell 1 and the inner cavity of the bellows 44, so that air can flow between the shell 1 and the bellows 44.

[0038] There are four columns 41 symmetrically distributed on the left and right sides of the connecting plate 42 . The columns 41 penetrate the connecting plate 42 , and a protrusion is provided at the rear end of the columns 41 to limit the connecting plate 42 from falling backwards, so as to limit the connecting plate 42 backwards.

[0039] When it is necessary to plug in the optical fiber, the optical fiber crystal head is inserted into the optical fiber interface 45 to complete the plug-in. After the plug-in is completed, through the action of the column 41 and the spring 43, the connecting plate 42 can drive the optical fiber interface 45 to elastically telescope and move, so that the crystal head and the optical fiber interface 45 are plugged in as an elastic fixed plug-in, which can buffer the movement and swing of the optical fiber, thereby ensuring the stability of the optical fiber plug-in. At the same time, during the movement of the connecting plate 42, it can also drive the bellows 44 to telescope and move, thereby generating a blast effect inside the bellows 44. With the action of the heat dissipation window 3 and the heat dissipation guide plate 2, it can accelerate the circulation of internal and external air, thereby improving the effect of heat conduction and heat dissipation.

[0040] like Figure 1-2As shown in 7-12, the heat dissipation component 6 includes a mounting groove 61. The top of the mounting frame 5 is provided with a mounting groove 61. There are three mounting grooves 61, namely, a mounting groove 61 located in the center of the top of the mounting frame 5, and two mounting grooves 61 symmetrically distributed on the left and right sides of the central mounting groove 61 on the top of the mounting frame 5. Slide grooves 62 are provided on the left and right sides of the mounting groove 61. Bending bars 63 are provided inside the mounting grooves 61. The front end of the bending bar 63 is fixedly connected to the inner wall of the mounting frame 5. Connecting columns 64 are evenly fixedly installed inside the bending bar 63 at the front and back. The connecting columns 64 pass through the end surface of the bending bar 63 from left to right and are slidably connected to the inside of the slide groove 62, so that the connecting columns 64 can slide inside the slide groove 62, and the connecting columns 64 located on the front side are limitedly rotated between the mounting grooves 61, so that the connecting columns 64 on the front side can only rotate. A cross bar is provided below the bending bar 63 inside the mounting frame 5. 65, the cross rod 65 can be folded, contracted and extended, and the left and right sides of the cross rod 65 are provided with side pins 66 for hinged connection of the cross rod 65 front and rear, and the ends of the left and right side pins 66 away from each other are fixedly installed with waist hole plates 67, and the bottom ends of the connecting columns 64 of the symmetrically distributed bending strips 63 are fixedly installed with connecting rods 68, while the bottom ends of the bending strips 63 located at the frontmost connecting column 64 are not installed with connecting rods 68, and a central pin 69 for hinge is provided at the central intersection of the cross rod 65, and the central pin 69 is fixedly connected to the bottom ends of the connecting columns 64 of the bending strips 63 located at the center of the installation frame 5 upward, while the central pin 69 located at the frontmost side is not fixedly connected to the bending strip 63 at the center of the installation frame 5, and the left and right sides of the front end of the cross rod 65 are limitedly rotated and connected with sliders 610, and the slider 610 is connected to the inside of the installation frame 5 by upward limit sliding, so that the slider 610 can slide inside the installation frame 5.

[0041] A straight plate area is provided at the rear end of the bending strip 63, and the straight plate area is limitedly slidably connected to the inside of the mounting frame 5. The bending area of ​​the bending strip 63 is located at the center between the connecting column 64 and the connecting column 64, and through the design of the notch in the bending area of ​​the bending strip 63, the bending area in the center between the connecting columns 64 is bent upward. Therefore, with the contraction of the cross rod 65, the bending strip 63 can be bent upward and tilted to achieve heat dissipation.

[0042] The connecting rod 68 extends downward and is slidably connected to the inside of the waist hole of the waist hole plate 67, so that the forward and backward movement of the waist hole plate 67 can drive the connecting rod 68 to move. Therefore, during the contraction and extension of the cross rod 65, the connecting rod 68 can be driven to move through the waist hole plate 67.

[0043] When the optical module is in use, the cross rod 65 is driven to fold and shrink. During the folding and shrinking process of the cross rod 65, the side pin shaft 66 and the central pin shaft 69 can also shrink to the front side, and the distance between them remains the same. By utilizing the sliding connection of the bottom connecting rod 68 of the connecting column 64 of the left and right bending bars 63 in the waist hole plate 67 at the side pin shaft 66, during the shrinking process of the side pin shaft 66, the connecting column 64 of the left and right bending bars 63 can also be driven to shrink. At the same time, by utilizing the fixed connection between the bottom end of the connecting column 64 of the central bending bar 63 and the central pin shaft 69, the connecting column 64 of the central bending bar 63 can also be driven to shrink, thereby making the connecting columns 64 of the bending bar 63 bend upward, so that the installation frame 5 can be ventilated with the outside air, thereby ensuring heat dissipation.

[0044] When not in use, the cross bar 65 can be extended backwards to spread the bending strip 63 backwards, thereby sealing the installation frame 5 to prevent dust from entering the installation frame 5.

[0045] like Figure 1-2 As shown in 4-6, the electrical connection component 7 includes a limit frame 71, and the limit frame 71 is fixedly installed inside the front side of the installation frame 5. The internal limit sliding connection of the limit frame 71 is connected with a slide bar 72, and the front end of the slide bar 72 is fixedly installed with an electrical interface 73, and the rear end of the slide bar 72 is fixedly connected with a bent cable, which is used to connect the electrical interface 73 with the photoelectric conversion component in the installation frame 5. Push blocks 74 are fixedly installed at the left and right ends of the slide bar 72, and the left and right ends of the push block 74 extend to the left and right sides of the installation frame 5, and are slidably connected inside the installation frame 5. The forward and backward movement of the slide bar 72 is achieved by pushing the push block 74. A fixed rod 75 is fixedly installed at the rear end of the slide bar 72, and the outer periphery of the fixed rod 75 is connected to the rear of the limit frame 71 A spring 2 76 is fixedly connected between the end side walls, and a limit strip 77 is provided on the front and rear sides of the slide bar 72 inside the installation frame 5. The bottom groove of the limit strip 77 faces the rear side, which is used to limit the push block 74 after the push block 74 moves to the front side of the limit strip 77, so that the slide bar 72 can be stably moved to the front side, so that the electrical interface 73 is stably exposed forward to complete the plug-in, and a pull rod 78 is fixedly installed in the middle of the top of the limit strip 77. The pull rod 78 is limited and slidably connected to the installation frame 5, and the top of the pull rod 78 extends upward to the top of the installation frame 5, so as to facilitate pulling the pull rod 78 upward, and a spring 3 79 is fixedly connected between the top of the limit strip 77 and the inner wall of the installation frame 5, and the spring 3 79 is wrapped around the outside of the pull rod 78.

[0046] like Figure 10-12 As shown, the fixed rod 75 extends backward, and the rear side is bent upward and fixedly connected to the central pin 69 located at the rear end, so that the sliding rod 72 drives the fixed rod 75 to move forward and backward, and can drive the cross rod 65 to contract and extend.

[0047] When the optical module needs to be connected to the circuit, the sliding bar 72 is first pushed forward by the pushing block 74, so that the sliding bar 72 drives the electrical interface 73 to extend to the front side. In the process of pushing block 74 moving forward, when the pushing block 74 contacts the limit bar 77, the limit bar 77 groove design can make the limit bar 77 compression spring three 79 move upward, and after the pushing block 74 passes the limit bar 77, the limit bar 77 pops up downward again to limit the pushing block 74, and then limit the sliding bar 72 and the electrical interface 73 to facilitate the insertion of the electrical interface 73. In the process of sliding bar 72 moving forward, the fixed connection between the fixing rod 75 at the rear end of the sliding bar 72 and the central pin 69 at the rear end can drive the cross rod 65 to shrink, and then drive the bending bar 63 to bend, so as to meet the heat dissipation and realize effective heat dissipation during the use of the optical module.

[0048] When not in use, the limit bar 77 is moved upward by pulling the pull rod 78 upward to release the limit on the push block 74, so that the fixing rod 75 moves backward under the action of the restoring force of the spring 2 76, so as to drive the electrical interface 73 to retract into the installation frame 5, and at the same time, the fixing rod 75 can push the cross rod 65 to extend, thereby flattening the bending strip 63 to seal the installation frame 5, thereby ensuring the sealing of the optical module when not in use and avoiding the entry of dust.

Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
