Technical Field

[0001] The present invention relates to the technical field of light emitters, and in particular to a high-efficiency light emitter. Background Art

[0002] Fiber-optic communication has developed into one of the main communication methods due to its many advantages such as large communication capacity, long transmission distance, and strong anti-electromagnetic interference ability; the optical transmitter is the main light source for fiber-optic communication and is the core component of fiber-optic communication.

[0003] For example, the Chinese patent "CN112234429B multi-channel laser transmitter and optical communication device" includes a base having a first side and a second side, and at least one through hole extending from the first side to the second side; a mounting plate mounted on the first side of the base; at least one main circuit board mounted in a corresponding through hole of the at least one through hole, the at least one main circuit board being used to receive power supply and radio frequency signals from the second side; a plurality of laser transmitter chips, each of which is mounted on the mounting board and is suitable for receiving power supply and radio frequency signals from the at least one main circuit board, thereby emitting multiple laser beams in different directions from each other; and a reflector group having multiple reflective surfaces for respectively receiving multiple laser beams from the multiple laser transmitter chips and reflecting them in a direction away from the base.

[0004] In order to facilitate production and manufacturing, the existing optical transmitters are mostly connected by ultrasonic welding. The components can only be used for specific optical fibers and cannot be replaced according to the different diameters of the optical fibers. There are limitations in use. In addition, the optical transmitter itself has poor heat dissipation effect, and heat is difficult to release to the outside in time, which can easily cause the temperature to exceed the limit, affecting the performance and service life of the optical transmitter. Summary of the invention

[0005] The present disclosure relates to a high-efficiency optical transmitter, which solves the problem that in order to facilitate production and manufacturing, various components of the existing optical transmitter are mostly connected by ultrasonic welding, which can only be applied to the needs of specific optical fibers and cannot be replaced according to different optical fiber diameters. The use has limitations, and the optical transmitter itself has poor heat dissipation effect, and heat is difficult to release to the outside in time, which easily causes the temperature to exceed the limit, especially affecting the efficiency and service life of the optical transmitter.

[0006] In a first aspect of the present disclosure, a high-efficiency optical transmitter is provided, specifically comprising: a laser body; a tube core sleeve is connected to the top of the laser body, and a fiber optic adapter is connected to the top of the tube core sleeve; two docking blocks are connected to the top of the tube core sleeve, and the docking blocks are connected to the fiber optic adapter; a movable sliding sleeve is sleeved on the outside of the tube core sleeve, and a force ring is connected to the inside of the tube core sleeve, and the force ring is connected to the movable sliding sleeve; a heat dissipation fan is fixedly installed on the bottom of the laser body by bolts.

[0007] Furthermore, the top of the laser body is connected to the tube core sleeve, two card blocks are provided on the outside of the laser body, and two card slots are provided on the bottom of the tube core sleeve. The card slots are L-shaped, and the card blocks are connected to the card slots of the tube core sleeve. The laser body and the tube core sleeve are connected together by rotating the card connection, which makes it easier to disassemble and assemble the laser body and the tube core sleeve.

[0008] Furthermore, an oblique tooth groove is provided on the outside of the laser body, and a limit hook is provided at the bottom of the tube core sleeve, and the end of the limit hook is connected to the oblique tooth groove provided on the laser body. When the clamping block moves to the innermost end of the clamping groove, the end of the limit hook is connected to the oblique tooth groove, and the oblique tooth groove cooperates with the limit hook to achieve a one-way locking effect on the tube core sleeve, thereby preventing the tube core sleeve from rotating in the opposite direction.

[0009] Furthermore, the bottom of the optical fiber adapter is plugged into the top of the tube core sleeve, two external plug holes are arranged outside the top of the tube core sleeve, and two internal slots are arranged at the bottom of the optical fiber adapter, and the internal slots are connected to the external plug holes of the tube core sleeve.

[0010] Furthermore, the length of the docking block is the sum of the depths of the outer hole and the inner slot. The docking block is inserted into the outer hole and the inner slot in a connected state. The movable sleeve is slidably connected to the outside of the tube core sleeve. The docking block contacts the inner side of the movable sleeve. When the optical fiber adapter and the tube core sleeve are plugged together, the outer hole and the inner slot are in a connected state. The docking block is inserted into the outer hole and the inner slot, which has the effect of fixing the plug-in position of the optical fiber adapter and the tube core sleeve.

[0011] Furthermore, the force-bearing ring is slidably connected to the inside of the tube core sleeve, a movable hole is arranged outside the tube core sleeve, two sliders are arranged outside the force-bearing ring, and the sliders are slidably connected to the movable holes arranged in the tube core sleeve.

[0012] Furthermore, a spring is installed inside the tube core sleeve, the bottom of the spring contacts the top of the laser body, and the top of the spring contacts the bottom of the force-bearing circle.

[0013] Furthermore, two external connecting holes are provided on the outside of the movable sleeve, which are connected with the movable hole provided on the tube core sleeve, and the end of the slider is located in the external connecting hole provided on the movable sleeve. When the docking block is inserted into the external plug hole and the inner slot, the force circle is affected by the spring thrust to drive the movable sleeve to move upward and reset, so that the inner side of the movable sleeve contacts the two docking blocks, which has a limiting effect on the docking blocks and prevents the docking blocks from falling out of the external plug hole and the inner slot.

[0014] Furthermore, an exhaust hole is arranged in a circumferential shape inside the laser body, the top of the exhaust hole is connected to the inside of the tube core sleeve, the bottom of the exhaust hole is connected to the heat dissipation fan, and an air inlet hole is arranged in a circumferential shape outside the tube core sleeve. When the laser body is powered on, the heat dissipation fan operates synchronously, and the air inside the tube core sleeve is pumped to the outside through the exhaust hole, and the outside air enters the tube core sleeve through the air inlet hole, and the laser body is cooled by the circulating air.

[0015] The present invention provides a high-efficiency light emitter, which has the following beneficial effects:

[0016] When the present invention is in use, the laser body and the tube core sleeve are connected together by a rotating clamping mode, so that the laser body and the tube core sleeve are easier to disassemble and assemble; when the clamping block moves to the innermost end of the clamping slot, the end of the limiting hook is connected to the oblique tooth groove, and the oblique tooth groove cooperates with the limiting hook to achieve a one-way locking effect on the tube core sleeve, thereby preventing the tube core sleeve from rotating in the opposite direction and ensuring the stability of the connection between the tube core sleeve and the laser body; when it is necessary to separate the tube core sleeve from the laser body, it is only necessary to pry the limiting hook outwards to separate the end of the limiting hook from the oblique tooth groove, and then the tube core sleeve can be rotated in the opposite direction to separate the tube core sleeve from the laser body.

[0017] In addition, according to the different diameters of optical fibers, optical fiber adapters with corresponding specifications can be selected and plugged into the tube core sleeve to better meet the needs of using optical fibers with different diameters. When the optical fiber adapter and the tube core sleeve are plugged together, the outer plug hole and the inner slot are connected, and the docking plug block is inserted into the outer plug hole and the inner slot. The docking plug block has the effect of fixing the plug-in position of the optical fiber adapter and the tube core sleeve; the spring has the effect of elastically resetting the movable sleeve and the force circle. When the docking plug block is plugged into the outer plug hole and the inner slot, the force circle is driven by the thrust of the spring. The movable sleeve moves upward to reset, so that the inner side of the movable sleeve contacts the two docking blocks, which plays a limiting effect on the docking blocks and prevents the docking blocks from falling out of the outer jack and the inner slot, thereby ensuring the stability of the connection between the tube core sleeve and the optical fiber adapter; when the tube core sleeve needs to be separated from the optical fiber adapter, it is only necessary to move the movable sleeve downward, the spring will be in a force-accumulating and contracted state, and the inner side of the movable sleeve will be separated from the two docking blocks, so that the docking blocks can be taken out from the outer jack and the inner slot, and the tube core sleeve can be separated from the optical fiber adapter, making it easier to disassemble, inspect and replace them later.

[0018] In addition, when the laser body is powered on, the cooling fan runs synchronously, and the air inside the tube core sleeve is pumped to the outside through the exhaust hole. The outside air enters the tube core sleeve through the air inlet hole, and the circulating air cools the laser body to maintain the laser body at a normal temperature, avoiding overheating of the laser body and ensuring the constant temperature operation of the laser body.

[0019] Other advantages, objectives and features of the present invention will be embodied in part through the following description, and in part will be understood by those skilled in the art through study and practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS
