[0039] See also Figures 1 to 3 In some embodiments of the present application, an optical attenuator 10 provided by the present application includes: a main body component 20, a locking portion 221 and a cap 30.

[0040] The locking portion 221 is fixedly disposed on the main assembly 20 . The cover cap 30 is slidably mounted on the main assembly 20 . The cover cap 30 is provided with a tail handle 31 and an unlocking portion 32 . The tail handle 31 extends out of the main assembly 20 .

[0041] If the tail handle 31 is pulled, the cover cap 30 slides relative to the main assembly 20 , and the unlocking portion 32 presses the locking portion 221 to unlock the optical attenuator 10 .

[0042] After the optical attenuator 10 is inserted into the external device, the optical attenuator 10 is fixedly connected to the external device through the locking portion 221. The tail handle 31 is pulled to make the cap 30 slide relative to the main assembly 20, so that the unlocking portion 32 presses the locking portion 221, thereby unlocking the optical attenuator 10, so that the optical attenuator 10 can be smoothly separated from the external device. The tail handle 31 is continued to be pulled to separate the optical attenuator 10 from the external device, thereby pulling the optical attenuator 10 out of the external device.

[0043] Since the tail handle 31 extends out of the main assembly 20, it is convenient to pull the tail handle 31 without touching the main assembly 20. This arrangement facilitates the plugging and unplugging of the optical attenuator 10 in a narrow space, and reduces the force on the main assembly 20 through the force on the tail handle 31, thereby reducing the risk of damage to the main assembly 20.

[0044] In this way, the optical attenuator 10 is easy to plug and unplug.

[0045] In some embodiments of the present application, the unlocking portion 32 is provided with a locking hole 33, and the locking portion 221 is provided with a locking hook 222. The locking hook 222 is located in the locking hole 33, and the locking hook 222 is protruded from the opening of the locking hole 33.

[0046] When the tail handle 31 is pulled, the unlocking portion 32 presses the locking portion 221 to lower the height of the locking hook 222 and release the hook.

[0047] After the optical attenuator 10 is inserted into the external device, the optical attenuator 10 is stably connected to the external device through the locking hook 222. The tail handle 31 is pulled, and the cap 30 slides relative to the main body assembly 20, so that the unlocking portion 32 presses the locking portion 221, so that the height of the locking hook 222 is lowered, and then it is unhooked from the external device, so that the optical attenuator 10 can be separated from the external device. The tail handle 31 is continued to be pulled, so that the optical attenuator 10 is separated from the external device, and the optical attenuator 10 is pulled out from the external device.

[0048] In some embodiments of the present application, the main assembly 20 includes a male component 21 and a female component 22, and the male component 21 is fixedly connected to the female component 22. The locking portion 221 is disposed on the female component 22, and the cap 30 is mounted on the female component 22. The unlocking portion 32 and the locking portion 221 are both facing the male component 21.

[0049] The optical attenuator 10 is inserted into the external device through the male part 21, and the locking part 221 makes it difficult to pull out the optical attenuator 10 from the external device. Pull the tail handle 31, so that the cap 30 slides relative to the female part 22, so that the unlocking part 32 presses the locking part 221, thereby unlocking the optical attenuator 10, so that the optical attenuator 10 can be smoothly separated from the external device. Continue to pull the tail handle 31, so that the optical attenuator 10 is separated from the external device, and the optical attenuator 10 is pulled out of the external device. The male part 21 is fixedly connected to the female part 22, so that the male part 21 and the female part 22 can move synchronously. When the cap 30 is pulled, the cap 30 slides relative to the female part 22 and reaches the limit position of the sliding of the cap 30, so that the cap 30 can drive the female part 22 to move synchronously. When the unlocking portion 32 unlocks the locking portion 221 , the cap 30 drives the female component 22 and the male component 21 to move synchronously, thereby separating the optical attenuator 10 from the external device, thereby pulling the optical attenuator 10 out of the external device.

[0050] In some embodiments of the present application, limiting grooves 223 are provided on both sides of the female head 22, and the cap 30 is provided with a limiting portion 34, which is inserted into the limiting grooves 223, and the length of the limiting grooves 223 is greater than the length of the limiting portion 34.

[0051] The cap 30 is slidably mounted on the female head 22 by inserting the limiting portion 34 into the limiting groove 223, and the limiting portion 34 is limited in the limiting groove 223, so that the cap 30 is difficult to be separated from the female head 22. When the tail handle 31 of the cap 30 is pulled, the limiting portion 34 slides in the limiting groove 223, so that the cap 30 can slide relative to the female head 22. The difference between the length of the limiting groove 223 and the length of the limiting portion 34 is the distance threshold for the cap 30 to slide relative to the female head 22. Pull the tail handle 31 to make the limiting portion 34 slide in the limiting groove 223. When the limiting portion 34 abuts against the inner wall of the limiting groove 223, the cap 30 can drive the female head 22 to move synchronously.

[0052] In some embodiments of the present application, the male component 21 is provided with a guide groove 211 , and the cap 30 is provided with a guide portion 35 . The guide portion 35 is inserted into the guide groove 211 , and the guide groove 211 is used to guide the guide portion 35 .

[0053] The cap 30 is combined with the male component 21 by inserting the guide portion 35 into the guide groove 211. When the cap 30 slides relative to the main assembly 20, the guide portion 35 is guided by the guide groove 211, so that the cap 30 can slide more reliably, reduce the jamming during the sliding process, and enable the optical attenuator 10 to be unlocked more smoothly at the external device.

[0054] In some embodiments of the present application, the first side wall 212 of the guide groove 211 is concave toward both sides of the guide groove 211, and the second side wall 36 of the guide portion 35 is convex toward both sides of the guide portion 35. The first side wall 212 and the second side wall 36 are attached to each other.

[0055] The first side wall 212 of the guide groove 211 is concave at both sides of the guide groove 211, and the second side wall 36 of the guide portion 35 is convex at both sides of the guide portion 35, so that the guide portion 35 is limited by the first side wall 212. When the tail handle 31 is pulled to make the unlocking portion 32 press the locking portion 221, the unlocking portion 32 is prevented from being lifted up by the locking portion 221, so that the optical attenuator 10 can be smoothly unlocked from the external device.

[0056] In some embodiments of the present application, the guide portion 35 is located on a side of the unlocking portion 32 facing the male component 21 .

[0057] By making the guide portion 35 located at the side of the unlocking portion 32 facing the male component 21, and thus making the guide portion 35 close to the male component 21, the guide portion 35 can be limited by the side wall of the guide groove 211, thereby limiting the degree of freedom of the unlocking portion 32, so that the unlocking portion 32 can only slide relative to the male component 21, and the unlocking portion 32 is prevented from being lifted up by the locking portion 221 when the tail handle 31 is pulled to make the unlocking portion 32 press the locking portion 221, so that the optical attenuator 10 can be smoothly unlocked from the external device.

[0058] In some embodiments of the present application, a plug slot 213 is provided on the side of the male component 21 facing the female component 22, and a plug connector 224 is provided on the side of the female component 22 facing the male component 21. The plug connector 224 is plugged into the plug slot 213 to keep the male component 21 and the female component 22 relatively fixed.

[0059] After the components of the optical attenuator 10 (such as the attenuation ferrule) are installed into the male connector 21 and the female connector 22, the male connector 21 and the female connector 22 are relatively fixed by inserting the plug connector 224 into the plug slot 213, and the components of the optical attenuator 10 are loaded through the male connector 21 and the female connector 22, so that the optical attenuator 10 can realize its function.

[0060] In some embodiments of the present application, fixing holes 214 are provided on the side walls of the plug-in slot 213 , and fixing protrusions 225 are provided on both sides of the plug-in connector 224 . The fixing protrusions 225 are adapted to the fixing holes 214 , and the fixing protrusions 225 are plugged into the fixing holes 214 .

[0061] After the plug connector 224 is inserted into the insertion slot 213 , the fixing protrusion 225 enters the fixing hole 214 , thereby reducing the risk of the plug connector 224 being pulled out of the insertion slot 213 , improving the stability of the combination of the male connector 21 and the female connector 22 , and thus improving the structural stability of the optical attenuator 10 .

[0062] In some embodiments of the present application, the fixing holes 214 are located on the left and right sides of the plug slot 213. At least one of the upper and lower sides of the plug slot 213 is provided with a notch 215, which penetrates the side wall of the plug slot 213.

[0063] When the plug connector 224 is inserted into the insertion slot 213, the fixing protrusion 225 squeezes the side wall of the insertion slot 213, thereby deforming the male component 21. The notch 215 is provided to reduce the force required for the male component 21 to deform, thereby facilitating the plug connector 224 of the female component 22 to be plugged in and out of the insertion slot 213 of the male component 21, making the disassembly and assembly of the optical attenuator 10 more convenient.
