Description

Technical Field

[0001] The utility model belongs to the field of laser technology, and in particular relates to a laser jumper position detection device. Background Art

[0002] In the prior art, the installation of jumper connectors and semiconductor lasers usually adopts the method of directly inserting or screwing the jumper connector into the nozzle of the semiconductor laser to connect the semiconductor laser and the optical fiber jumper connector. However, connecting the semiconductor laser and the optical fiber jumper connector in this way cannot guarantee that the two are completely connected in place, and light leakage is prone to occur. A small amount of light leakage will cause the jumper connector to heat up, and severe light leakage will cause the jumper connector to burn or even explode. Especially when the installer is negligent or forgetful, if the semiconductor laser and the optical fiber jumper connector are not completely connected, other personnel will not be able to quickly determine whether they are connected in place. They need to manually check and confirm one by one before continuing with subsequent work, which is time-consuming and labor-intensive. Utility Model Content

[0003] In view of the deficiencies in the prior art, the present invention provides a laser jumper position detection device, which can effectively solve the above problems.

[0004] To achieve the above-mentioned purpose, the present invention adopts the following technical solution: a laser jumper position detection device, comprising:

[0005] A pressure plate having a circular hole, wherein the pressure plate is slidably sleeved on the outside of the tail tube through the circular hole, the tail tube is arranged on the side wall of the laser housing, the tail tube is used to install the optical fiber jumper, and a nut is movably sleeved on the outside of the optical fiber jumper, and the tail tube is provided with an external thread at one end away from the laser housing, the nut is screwed with the external thread, and the nut is abutted against the pressure plate at one end close to the laser housing;

[0006] a spring, sleeved on the outside of the tail pipe, one end of the spring being connected to the pressure plate, and the other end of the spring being connected to the tail pipe;

[0007] A micro button switch is arranged on the side wall of the laser housing;

[0008] A light emitting component is arranged on the side wall of the laser housing and is electrically connected to the micro button switch.

[0009] Preferably, the light-emitting element is a light-emitting diode.

[0010] Preferably, the micro button switch is arranged on the side wall of the laser housing through a pad.

[0012] Preferably, an insulating plate is provided between the backing plate and the laser housing.

[0013] Preferably, the insulating plate and the backing plate are fixed to the side wall of the laser housing by bolts.

[0014] Preferably, a light guiding channel is formed in the tail pipe, and the optical fiber jumper is inserted into the light guiding channel.

[0015] Preferably, a limiting strip is fixed on the outer wall of the tail pipe, the limiting strip is arranged along the axial direction of the tail pipe, a limiting groove is provided on the inner wall of the circular hole, and the limiting strip is embedded in the limiting groove.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. The utility model provides a laser jumper position detection device. When installing a fiber jumper, the jumper connector is inserted into the tail tube, and then the nut is screwed to the external thread of the tail tube by rotating the nut. During the movement of the nut, the pressure plate can be pushed gradually closer to the laser housing until the pressure plate presses the micro button switch and the light-emitting component is lit. At this time, the fiber jumper is just completely connected to the tail tube. When the nut is rotated in the opposite direction, the nut gradually moves away from the laser housing, the spring pushes the pressure plate to disengage the micro button switch, and the light-emitting component goes out, indicating that the fiber jumper is not completely connected to the tail tube. In this way, subsequent personnel can quickly determine whether the semiconductor laser and the fiber jumper connector are completely connected by whether the light-emitting component is lit, without the need for manual inspection, saving time and effort.

[0018] 2. The utility model provides a laser jumper position detection device, which enables the pressure plate to slide stably through the setting of the limit bar, preventing the pressure plate from rotating around the tail pipe and deviating, resulting in the pressure plate being unable to contact the micro button switch.

[0024] The present invention will be further described in detail below in conjunction with specific embodiments so that those skilled in the art can understand the present invention more clearly.

[0025] It should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood broadly. For example, they can refer to fixed connections, detachable connections, or integrated structures. Those skilled in the art will understand the specific meanings of such terms in this patent based on specific circumstances.

[0026] Example 1

[0027] See also Figure 1 This embodiment provides a laser jumper position detection device, comprising:

[0028] The pressure plate 4 has a circular hole. The pressure plate 4 is slidably sleeved on the outside of the tail pipe 2 through the circular hole. The pressure plate 4 can slide axially along the tail pipe 2.

[0029] The tail tube 2 is provided on the side wall of the laser housing 1, and the tail tube 2 is used to install the optical fiber jumper 9. The laser housing 1 provides a platform for installing various components. For example, a through hole corresponding to the tail tube 2 is provided on the side wall of the laser housing 1, and the tail tube 2 is installed in the through hole. The tail tube 2 encloses a light guide channel, and the light guide channel is used to insert the optical fiber jumper 9. A limiting step is provided on the inner wall of the tail tube 2, and a stop ring surface corresponding to the limiting step is provided on the optical fiber jumper 9. When the stop ring surface of the optical fiber jumper 9 conflicts with the limiting step, the optical fiber jumper 9 is fully connected to the tail tube 2.

[0030] The outer sleeve of the optical fiber jumper 9 is provided with a nut 10. For example, see Figure 1-2 A limit ring is coaxially fixed to the outside of the optical fiber jumper 9. The diameter of the limit ring is larger than the diameter of the left end opening of the nut 10, but smaller than the diameter of the right end opening of the nut 10. The limit ring is located inside the nut 10. In this way, when the nut 10 moves to the right, it can drive the limit ring to move to the right, and the nut 10 cannot be separated from the optical fiber jumper 9. If the nut 10 needs to be removed, move the nut 10 to the left, and the limit ring can be separated from the right end opening of the nut 10.

[0031] The end of the tail pipe 2 away from the laser housing 1 is provided with an external thread, and the nut 10 is screwed to the external thread. The end of the nut 10 close to the laser housing 1 abuts against the pressure plate 4. Specifically, inserting the optical fiber jumper 9 into the light guide channel of the tail pipe 2 can screw the nut 10 to the external thread. By rotating the nut 10, the nut 10 can move axially along the tail pipe 2, and push the pressure plate 4 to move axially along the tail pipe 2.

[0032] Spring 3 is mounted on the outside of tail pipe 2. One end of spring 3 is connected to pressure plate 4, and the other end of spring 3 is connected to tail pipe 2. When nut 10 pushes pressure plate 4 closer to laser housing 1, spring 3 is compressed. When nut 10 rotates in the opposite direction away from laser housing 1, spring 3 can push pressure plate 4 away from laser housing 1.

[0033] The micro-button switch 8 is mounted on the side wall of the laser housing 1. The position of the micro-button switch 8 needs to be pre-designed. For example, when the nut 10 pushes the pressure plate 4 gradually closer to the laser housing 1 until the pressure plate 4 just presses the micro-button switch 8, the light-emitting element 11 is illuminated. At this time, the stop ring surface of the fiber jumper 9 just contacts the limit step, that is, the fiber jumper 9 is completely connected to the tail tube 2, and the position of the micro-button switch 8 is now the predetermined position.

[0034] The light emitting element 11 is disposed on the side wall of the laser housing 1 and is electrically connected to the micro button switch 8. For example, the light emitting element 11 is a light emitting diode. The positive and negative electrodes of the light emitting diode can be connected to the positive and negative electrodes of the micro button switch 8 via wires.

[0035] Based on the above structure, when installing the fiber optic jumper, the fiber optic jumper 9 is pre-inserted into the tail tube 2. By rotating the nut 10, the nut 10 can push the pressure plate 4 gradually close to the laser housing 1 during movement, and at the same time drive the fiber optic jumper 9 gradually deeper into the tail tube 2 until the pressure plate 4 presses the micro button switch 8 and the light-emitting component 11 is lit. At this time, the fiber optic jumper 9 is completely connected to the tail tube 2.

[0036] When the nut 10 is rotated in the reverse direction, the nut 10 gradually moves away from the laser housing 1, the spring 3 pushes the pressure plate 4 to disengage the micro button switch 8, and the light-emitting element 11 goes out, indicating that the optical fiber jumper is not completely connected to the tail tube 2.

[0037] In this way, subsequent personnel can quickly determine whether the semiconductor laser and the optical fiber jumper connector are fully connected by observing whether the light-emitting element 11 is lit, without the need for manual inspection, saving time and effort.

[0038] Please see again Figure 1In this embodiment, the micro button switch 8 can be set on the side wall of the laser housing 1 through the pad 6. By changing the thickness of the pad 6, the position of the micro button switch 8 can be adjusted, thereby making the micro button switch 8 at a predetermined position.

[0039] The micro button switch 8 can be fixed on the backing plate 6 by insulating adhesive. An insulating plate 5 can be provided between the backing plate 6 and the laser housing 1 to effectively improve the insulation performance of the device.

[0040] The insulating plate 5 and backing plate 6 are fixed to the side wall of the laser housing 1 via bolts 7. For example, the side wall of the laser housing 1 has two screw holes, and correspondingly, the insulating plate 5 and backing plate 6 each have two screw holes. The ends of the bolts 7 are passed through the screw holes of the backing plate 6 and the screw holes of the insulating plate 5, and then screwed into the screw holes on the side wall of the laser housing 1. This secures the insulating plate 5 and backing plate 6 to the side wall of the laser housing 1. Furthermore, the end caps of the bolts 7 provide support, preventing the pressure plate 4 from moving too far and damaging the micro-button switch 8.

[0041] Example 2

[0042] See also Figure 3 In order to improve the sliding stability of the pressure plate 4, on the basis of Example 1, a limit strip 12 is fixed on the outer wall of the tail pipe 2, the limit strip 12 is arranged axially along the tail pipe 2, and a limit groove 13 is provided on the inner wall of the circular hole, and the limit strip 12 is embedded in the limit groove 13.

[0043] Among them, the setting of the limit strip 12 prevents the pressure plate 4 from rotating around the tail pipe 2, and thus the pressure plate 4 can only slide axially along the tail pipe 2, which can prevent the pressure plate 4 from deviating and causing the pressure plate 4 to be unable to contact the micro button switch 8.

[0044] The mechanisms, components and parts not specifically described in the present invention are all existing structures in the prior art and can be directly purchased from the market.
