Description

Technical Field

[0001] The utility model belongs to the technical field of optical module self-locking, and in particular relates to a novel hidden self-locking structure of an optical module. Background Art

[0002] Optical modules are optoelectronic devices that perform photoelectric and electro-optical conversion. They consist of optoelectronic components, functional circuits, and optical interfaces, encompassing both transmitting and receiving components. Simply put, an optical module's function is to convert electrical signals at the transmitter into optical signals, transmit them via optical fiber to the receiver, and then convert the optical signals back into electrical signals at the receiver. The optical module must be enclosed in a self-locking structure to ensure secure installation.

[0003] The current assembly structure of optical modules is unreasonable, which leads to the following two technical problems:

[0004] (1) The optical module generates heat when it is powered on. In the past, the optical module was directly built into the metal frame, and the metal frame was used to self-lock the optical module. The metal frame needs to wrap the optical module to protect the optical module. The metal frame is a sealed structure. There is no corresponding heat conduction measure between the optical module and the metal frame. The heat generated by the optical module will accumulate on the metal frame. The sealed shell affects the effect of heat dissipation from the optical module to the air. Overheating of the optical module will reduce the operating speed and cause damage. Therefore, external heat dissipation measures are required to dissipate heat from the optical module, and a gap must be reserved between the metal frame and the optical module to allow air to flow more smoothly to carry away the heat. At this time, the metal frame needs to be made particularly large and difficult to match the shape of the optical module. It is bulky and bloated. This heat dissipation measure makes the self-locking structure appear exposed and complicated, affecting the aesthetics of the optical module.

[0005] (2) Each component connection requires many screws to fix it, which takes extra time and increases the processing and manufacturing cost. The screws exposed at the connection of each component will make the connection part visible. The screws are in contact with the air for a long time and will rust after wear. The use of screw connection method requires additional procurement costs. The screws will also affect the appearance of the optical module. The disassembly process during later maintenance is very time-consuming. Utility Model Content

[0006] The technical problem to be solved by the utility model is to overcome the defects of the prior art and solve the problem that the prior self-locking structure is unreasonable and causes high temperature to the optical module and is inconvenient to assemble.

[0007] The technical solution adopted by the present invention to solve the technical problem is: a new type of hidden self-locking structure of an optical module, including a metal frame:

[0008] A pair of heat-conducting frames symmetrically distributed up and down are embedded in the metal frame, and the upper and lower heat-conducting frames are plugged into each other. A positioning lock piece is inserted into the outer wall between the heat-conducting frames and is embedded in the right end between the metal frame and the heat-conducting frame;

[0009] A second buckle position is provided at both the front and rear ends between the upper and lower heat-conducting frames, and a first buckle position is provided at both the front and rear ends of the positioning lock piece to buckle with the interior of the adjacent second buckle position;

[0010] The front and rear sides of the left end of the positioning lock piece are both integrally formed with self-locking convex blocks, and the right end of the metal frame is provided with a self-locking concave buckle groove embedded in the left end of the adjacent self-locking convex block.

[0011] In a preferred technical solution of the present invention, the metal frame and the positioning lock piece are made of aluminum alloy, and the heat-conducting frame is made of a composite of high thermal conductivity ceramics and graphene.

[0012] In a preferred technical solution of the present invention, a circuit board, a light emitter and a condenser are embedded in the interior of the heat-conducting frames from left to right in sequence.

[0013] In a preferred technical solution of the present invention, the right end of the positioning lock piece is connected to a positioning handle through a lock buckle.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The circuit board, the light emitter and the light concentrator are sequentially embedded in the heat-conducting frame from left to right, so that the circuit board, the light emitter and the light concentrator are arranged in sequence, so that the circuit board, the light emitter and the light concentrator constitute a complete optical module. The circuit board is used to control the light emitter to emit light, and the light concentrator is used to concentrate the light emitted by the light emitter. This design improves the overall performance of the optical module, realizes the function of compact integration, reduces the space occupied by the circuit board, the light emitter and the light concentrator in the self-locking structure, optimizes the optical effect, and is conducive to the integration of the optical module structure.

[0016] The two symmetrically distributed heat-conducting frames are fixed by the positioning lock pieces through the self-locking convex blocks and self-locking concave grooves between them. This ensures that the optical module has excellent structural stability during use and avoids loosening or displacement caused by vibration or external force. This has the advantage of high structural stability and improves the self-locking performance of the optical module.

[0017] The thermal conductive frame separates the optical module from the metal frame and provides a stable supporting skeleton structure for the circuit board, light emitter and condenser. The thermal conductive frame forms a thermal insulation medium between the metal frame and the optical module. The thermal conductive frame uses high thermal conductivity ceramic and graphene composite materials with excellent heat dissipation performance. The use of high thermal conductivity ceramic and graphene as a thermal conductive frame to absorb heat and support the optical module can quickly conduct the heat generated inside the optical module and dissipate it into the air, reducing the temperature of the optical module to increase the operating speed and extend the service life;

[0018] The thermal conductive frame assembles the optical module into the inside of the metal frame. The first clip position and the second clip are used together to firmly connect the positioning lock piece to the right end of the metal frame and firmly fit the surface of the thermal conductive frame. The self-locking convex block and the self-locking concave groove are used together to keep the positioning lock piece tightly and firmly connected to the metal frame. The installation and removal steps of the optical module can be completed without using complicated tools, which saves time and energy, simplifies the structure, and eliminates the assembly process of screwing during the assembly of the optical module. The surface of the metal frame can be sprayed with a variety of colors to appear colorful. Eliminating the screw connection method allows the thermal conductive frame to be hidden inside the metal frame, thereby improving the aesthetics of the optical module installed inside the metal frame. The shape of the metal frame and the shape of the optical module fit each other to reduce the volume. The small size can save material costs. The optical module is more concealed during installation. The structural layout is reasonable, which reduces production costs and speeds up production. BRIEF DESCRIPTION OF THE DRAWINGS

The aluminum alloy material enables the metal frame 1 to have excellent thermal conductivity. When the module is powered on, it generates heat and produces a temperature difference higher than that of the thermally conductive frame 4.

The outside air flows through the surface of the metal frame 1, which can quickly conduct the heat generated inside the optical module and dissipate it into the air, thereby reducing the temperature of the optical module to increase the operating speed and extend the service life.
