Abstract
Description
Technical Field
[0001] This utility model relates to the field of optical device technology, and more specifically, to an active optical device for optical signal detection. Background Technology
[0002] Optical devices typically include an optical emitting device and an optical receiving device. The emitting laser and the receiving detector are usually designed at a 90-degree right angle. However, during installation, optical devices sometimes require the emitting laser and the receiving detector to be designed at other angles or parallel to each other. Therefore, existing optical devices require methods such as bent pin connections, flexible circuit boards, and circuit board adapters to achieve electrical connections between the pins and the circuit board during installation. However, this design causes the optical device to transmit light signals through bending, increasing the signal loss rate. Therefore, this invention proposes an active optical device for light signal detection to solve the above problems. Utility Model Content

Detailed Implementation
[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0024] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0025] Please see Figure 1-2 The present invention provides a technical solution: an active optical device for optical signal detection, including a housing 10, an adapter 20 disposed on one side of the housing 10, a receiving detector 30 disposed on the right side of the housing 10, and an emitting laser 40 disposed on the other side of the housing 10. The emitting laser 40 is provided with an adjustment component for adjusting the angle of the emitting laser 40 and a limiting component for fixing the adjustment component.
[0026] Please see Figure 1-4 The adjustment assembly includes a connecting plate 50 on one side of the laser emitter 40, a movable rod 5001 on one side of the front end of the connecting plate 50, a fixed rod 5002 on the other side of the front end of the connecting plate 50, two fixed frames 5003 on one side of the connecting plate 50, a connecting rod 5004 on the fixed frame 5003, and an adjustment plate 5005 on the other end of the connecting rod 5004. One end of the connecting rod 5004 is hinged to the fixed frame 5003, and the other end of the connecting rod 5004 is hinged to the adjustment plate 5005. The connecting rod 5004 can support and connect the connecting plate 50, so that after the connecting plate 50 is rotated to adjust the angle, the adjustment plate 5005 can be fixed by the limiting assembly, and the connecting plate 50 can be fixed together.
[0027] The housing 10 has two symmetrically distributed fixing slots 5008 on one side, and a fixing hole 5009 at the rear. The movable rod 5001 is rotatably connected to the right fixing slot 5008, and the connecting rod 5004 passes through the fixing hole 5009 and extends into the interior of the housing 10.
[0028] Meanwhile, the movable rod 5001 has two vertically symmetrically distributed first connecting blocks 5006 on its exterior, and the fixed rod 5002 has two vertically symmetrically distributed second connecting blocks 5007 on its exterior. The other end of the first connecting block 5006 is fixed to one side of the front of the connecting plate 50, and the other end of the second connecting block 5007 is fixed to the other side of the front of the connecting plate 50. Two vertically symmetrically distributed slots 5010 are provided on one side of the housing 10. The upper and lower ends of the fixed rod 5002 are respectively inserted into the two slots 5010 and fitted with a gap. In this design, the angle between the receiving detector 30 and the emitting laser 40 can be adjusted according to the installation requirements during the installation of the optical device. Specifically, the emitting laser 40 is rotated around the movable rod 5001 as the pivot. The emitting laser 40 can rotate up to 90 degrees. At this time, the receiving detector 30 and the emitting laser 40 are in a parallel position. This design avoids the need for bent pin connections, flexible circuit boards, circuit board adapters, etc. to achieve electrical connection between the pins and the circuit board during installation. It also avoids the need for the optical device to bend and transmit when detecting optical signals, thus reducing the loss rate of the light source signal.
[0029] Please see Figure 1-2 and Figure 4 The limiting assembly includes two sliders 51 disposed on the left and right sides of the adjusting plate 5005, two screws 5101 disposed on the upper and lower sides of the adjusting plate 5005, nuts 5102 disposed on the screws 5101, and two slide grooves 5103 disposed on the left and right sides of the inner wall of the housing 10.
[0030] It is understandable that two symmetrically distributed limiting holes 5105 are provided on both the upper and lower sides of the housing 10. The limiting holes 5105 are connected to the grooves 5104. The four screws 5101 pass through the four limiting holes 5105 respectively and are slidably connected to the limiting holes 5105. When the laser emitter 40 is rotated to adjust the angle, the adjusting plate 5005 moves backward, which at the same time drives the screws 5101 to move backward in the limiting holes 5105.
[0031] It should be noted that two symmetrically distributed grooves 5104 are provided on both the upper and lower sides of the housing 10. Four sliders 51 are inserted into the four sliding grooves 5103 and slidably connected to them. The cooperation between the sliders 51 and the sliding grooves 5103 can support the adjusting plate 5005 and allow it to move back and forth. The nut 5102 is threadedly connected to the screw 5101, and the nut 5102 fits tightly with the groove 5104. The screw 5101 is located inside the groove 5104. The highest point of the top screw 5101 is lower than the top of the housing 10, and the lowest point of the bottom screw 5101 is higher than the bottom of the housing 10, so that the top and bottom of the optical device can remain flat during installation.
[0032] Finally, since the detection of optical signals by optical devices is an existing technology, this utility model will not elaborate on the specific connection relationship between the housing 10, adapter 20, receiver detector 30, and emitting laser 40, or the working principle of how to detect optical signals.
[0033] Specifically, the working principle of this active optical device used for optical signal detection is as follows:
[0034] During use, the angle between the receiving detector 30 and the emitting laser 40 can be adjusted according to specific installation requirements. Specifically, the emitting laser 40 is rotated to a suitable position using the movable rod 5001 as the pivot. During the rotation, the emitting laser 40 pulls the adjusting plate 5005 to the rearward side via the connecting rod 5004. During the movement, the adjusting plate 5005 drives the screw 5101 to move backward. Finally, the position of the adjusting plate 5005 can be fixed by rotating the nut 5102 to fit tightly into the groove 5104. When the position of the adjusting plate 5005 is fixed, the angle of the emitting laser 40 is also fixed. This design avoids the need for bent pin connections, flexible circuit boards, circuit board adapters, etc., to achieve electrical connection between the pins and the circuit board during installation. It also avoids the need for the optical device to bend and transmit the light signal, reducing the signal loss rate of the light source.
[0035] It should be noted that the specific models and specifications of the housing 10, adapter 20, receiver detector 30, and laser emitter 40 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.
