Abstract
Description
Technical Field
[0001] This invention relates to the field of light emitter technology, and in particular to a compact light emitter. Background Technology
[0002] In optical fiber communication, in order to convert electrical signals in the optical fiber communication system into optical signals to achieve high-speed, long-distance signal transmission, an optical transmitter is usually installed in the optical fiber communication system. Existing optical transmitters usually consist of a base, pads, light-emitting diodes (LDs), monitoring diodes (PDs), lenses, core sleeves, and adapters.
[0003] For example, utility model patent application CN202023119590.X discloses a high-frequency optical transmitter, specifically a socket, a cap, and a lens. The socket includes a base, a first pad vertically mounted on the base, a second pad horizontally mounted on the base, an LD chip on the upper surface of the second pad, and several pins. The first pad has a first metal plating layer, which includes a first region on the upper surface of the first pad and a second region on the side of the first pad and connected to the first region. The second region is eutectic bonded to the signal transmission pins among the pins. The upper surface of the second pad has a second metal plating layer. The LD chip is electrically connected to the second metal plating layer, and the second metal plating layer is electrically connected to the first region via multiple metal wires. By electrically connecting multiple metal wires in the first region and the second metal plating layer, the transmission requirements of high-frequency signals are met, and the structure is simple and easy to manufacture. Additionally, this utility model also discloses a coaxial high-frequency optical transmitter assembly.
[0004] However, existing optical transmitters often encounter various uncontrollable factors during transportation, such as uneven roads, vehicle bumps, and improper handling during loading and unloading. These factors can cause the pins of the optical transmitter to collide with other goods or transport vehicles, resulting in scratches, wear, or even bending of the pins. This affects the normal operation of the entire optical transmitter and makes it inconvenient to use. Summary of the Invention
[0005] In view of this, the present invention provides a compact light emitter with a protective sleeve that protects the pins of the light emitter. The protective sleeve is positioned by a connecting block and an auxiliary block, ensuring it fits accurately over the pins and provides protection during transport. A locking rod locks the connecting block and auxiliary block. When the protective sleeve is installed at the bottom of the heat sink, a control push plate is inserted into the heat sink. After insertion, the control push plate pushes an auxiliary slide upwards and stretches an auxiliary spring. This movement causes a control wedge to press against the control slide, moving it within the adapter and stretching the control spring. The movement of the control slide also moves the connecting carriage, which in turn causes two sealing plates to automatically close, sealing the light-transmitting holes of the ferrule.
[0006] This invention provides a compact light emitter with the following purpose and function: a base; two pins are symmetrically and fixedly connected to the bottom end face of the base; a heat sink is fixedly connected to the bottom end face of the base; the upper parts of the two pins are both disposed within the heat sink; a light-transmitting lens is fixedly connected to the center of the top end face of the base; a gasket is fixedly connected inside the base; a light-emitting diode (LD) is fixedly connected to the center of the top end face of the gasket; a monitoring device (PD) is disposed on the right side of the top end face of the gasket; the monitoring PD and the light-emitting LD are aligned; a core sleeve is disposed on the upper part of the base; an adapter is disposed on the upper part of the core sleeve; a ferrule is fixedly connected inside the adapter; the ferrule and the light-transmitting lens are aligned.
[0007] Furthermore, a protective sleeve is provided on the bottom surface of the heat sink; the lower parts of the two pins are both located inside the protective sleeve; two auxiliary blocks are symmetrically fixedly connected to the upper part of the protective sleeve; two connecting blocks are symmetrically fixedly connected to the outside of the heat sink; the two connecting blocks are respectively inserted into the two auxiliary blocks.
[0008] Furthermore, a locking rod is slidably connected to each of the two auxiliary blocks; the two locking rods are respectively inserted into the two connecting blocks; a connecting spring is fixedly connected to the inner side of each of the two locking rods; the ends of the two connecting springs are respectively fixedly connected to the outside of the two auxiliary blocks.
[0009] Furthermore, four sets of buffer springs are fixedly connected in a ring array inside the protective casing; a rubber arc plate is fixedly connected to the end of each of the four sets of buffer springs; and the four rubber arc plates are aligned with the position of the tube feet.
[0010] Furthermore, the top surface of the protective sleeve is symmetrically and fixedly connected to two control push plates; two auxiliary slides are slidably connected inside the tube sleeve; the ends of the two auxiliary slides pass through the base and are set inside the heat sink; the positions of the two auxiliary slides are respectively aligned with the positions of the two control push plates; an auxiliary spring is fixedly connected to the outer side of each of the two auxiliary slides; the ends of the two auxiliary springs are fixedly connected inside the tube sleeve.
[0011] Furthermore, a control wedge is fixedly connected to the top surface of each of the two auxiliary slides; two control slides are symmetrically fixedly connected inside the adapter; an inclined surface is provided on the outer side of each of the two control slides; a set of control springs is fixedly connected to the upper outer side of each of the two control slides; the ends of the two sets of control springs are fixedly connected inside the adapter; a connecting carriage is fixedly connected to the top surface of each of the two control slides; a sealing plate is fixedly connected to the inner side of each of the two connecting carriages; and the two sealing plates are aligned with the position of the insert.
[0012] Furthermore, a heat-conducting column is fixedly connected to the bottom end face of the base; the heat-conducting column is fixedly connected to the bottom end face of the inner wall of the heat sink.
[0013] Furthermore, the heat sink has multiple sets of heat dissipation holes arranged in a ring array on its exterior; all sets of heat dissipation holes are circular holes; and all sets of heat dissipation holes are aligned with the position of the heat conduction pillar.
[0014] Beneficial effects
[0015] This invention utilizes connecting blocks and auxiliary blocks to position the protective casing, ensuring it fits accurately over the pins. Locking rods secure the connecting blocks and auxiliary blocks, fixing the protective casing to the heat sink. This provides protection for the pins during transport, preventing direct impact and scratches from external objects, thus protecting the pins' physical integrity and ensuring stable connection. Furthermore, the rubber arc plate and buffer springs absorb vibrations and impacts during transport, maintaining stable contact even with slight vibrations or displacement of the protective casing. This ensures the safety and reliability of the high-frequency optical transmitter during transport, reduces the risk of damage, and effectively improves the practicality of the optical transmitter.
[0016] When the protective cover is installed at the bottom of the heat sink, the control push plate inserts into the heat sink and pushes the auxiliary slide upward. Subsequently, a series of transmissions move the connecting slide. As the connecting slide moves, it automatically closes two sealing plates, sealing the light-transmitting holes of the ferrule. This prevents dust, moisture, grease, and other contaminants from entering the light emitter, protecting the ferrule and internal components from contamination and maintaining a clean internal environment. This effectively improves the convenience of the light emitter, making it easier to use.
[0017] The heat-conducting pillars allow heat generated inside the base to be quickly transferred into the heat sink, and the heat is then quickly dissipated through the heat dissipation holes, improving the heat dissipation efficiency of the optical transmitter, preventing overheating of the light-emitting LD and monitoring PD, and effectively extending the lifespan of the optical transmitter.

[0034] The heat sink 109 has a protective cover 112 on its bottom surface; the lower parts of the two pins 108 are both located inside the protective cover 112; the upper part of the protective cover 112 is symmetrically and fixedly connected to two auxiliary blocks 114; the outside of the heat sink 109 is symmetrically and fixedly connected to two connecting blocks 113; the two connecting blocks 113 are respectively inserted into the two auxiliary blocks 114.
[0035] Each of the two auxiliary blocks 114 has a locking rod 115 slidably connected to it; the two locking rods 115 are respectively inserted into the two connecting blocks 113; a connecting spring 116 is fixedly connected to the inner side of each of the two locking rods 115; the ends of the two connecting springs 116 are respectively fixedly connected to the outside of the two auxiliary blocks 114.
[0036] The protective sleeve 112 contains four sets of buffer springs 118 fixedly connected in a ring array; each of the four sets of buffer springs 118 has a rubber arc plate 117 fixedly connected to its end; and all four rubber arc plates 117 are aligned with the position of the tube foot 108.
[0037] The protective sleeve 112 has two control push plates 119 symmetrically and fixedly connected to its top surface; two auxiliary slides 120 are slidably connected inside the core sleeve 105; the ends of the two auxiliary slides 120 pass through the base 1 and are set inside the heat sink 109; the two auxiliary slides 120 are respectively aligned with the positions of the two control push plates 119; an auxiliary spring 121 is fixedly connected to the outer side of each of the two auxiliary slides 120; the ends of the two auxiliary springs 121 are fixedly connected inside the core sleeve 105.

[0039] The specific usage and function of this embodiment: In this invention, the components described in this application are closely connected, making the structure of the light emitter more compact. The protective housing 112 can be positioned by the connecting block 113 and the auxiliary block 114, allowing the protective housing 112 to accurately fit over the pin 108, providing protection for the pin 108 during transportation. The locking rod 115 can lock the connecting block 113 and the auxiliary block 114. The protective housing 112 is fixed to the heat sink 109 to ensure the protective effect of the protective housing 112 on the pins 108 during transportation. When it is necessary to install the light emitter, simply pull the locking rod 115 to make the locking rod 115 slide in the auxiliary block 114 and stretch the connecting spring 116 to release the limit on the connecting block 113. At this time, the operator can remove the protective housing 112 to expose the pins 108 for installation of the light emitter. The elastic potential of the buffer spring 118 itself will help to protect the light emitter. The system ensures that the rubber arc plate 117 remains in close contact with the pin 108. Simultaneously, the elastic potential energy of the buffer spring 118 and the elasticity of the rubber arc plate 117 provide good cushioning protection for the pin 108. When the protective sleeve 112 is impacted, the impact on the pin 108 is reduced, further protecting the pin 108. When the protective sleeve 112 is installed at the bottom of the heat sink 109, the control push plate 119 will insert into the heat sink 109. After 9 seconds, the auxiliary slide 120 will be pushed upward and the auxiliary spring 121 will be stretched. As the auxiliary slide 120 moves, the control wedge 122 will press against the control slide 123, causing the control slide 123 to move within the adapter 106 and stretch the control spring 124. As the control slide 123 moves, the connecting slide 125 will move. As the connecting slide 125 moves, the two sealing plates 126 will automatically close, sealing the light-transmitting hole of the insert 107.

[0041] Based on Example 1, please refer to Figures 1 to 4 As shown, it includes: a heat-conducting column 110 and a heat dissipation hole 111. A heat-conducting column 110 is fixedly connected to the bottom end face of the base 1; the heat-conducting column 110 is fixedly connected to the bottom end face of the inner wall of the heat sink 109.
[0042] The heat sink 109 has multiple sets of heat dissipation holes 111 arranged in a ring array on its exterior; all sets of heat dissipation holes 111 are circular holes; and all sets of heat dissipation holes 111 are aligned with the heat conduction pillars 110.
[0043] The specific usage and function of this embodiment: In this invention, the heat generated in the base 1 can be quickly introduced into the heat sink 109 for heat dissipation by the heat conduction column 110, so as to prevent the light-emitting LD 102 and the monitoring PD 103 from overheating. The heat dissipation hole 111 can quickly introduce the hot air into the heat sink 109 by the heat conduction column 110 for heat dissipation, thereby improving the heat dissipation efficiency of the light emitter.
