Fig. 18 is a partial structural schematic view of a light module when a handle is rotated according to an embodiment of the present application. As shown in fig. 5, 6 and 11-18, in the present embodiment, the unlocking member 203 includes a handle 2031 and an unlocking device 2032, and the outer surface of the lower housing 202 is provided with a storage groove 2021, a fastening member 2022, a first stopper 2023 and a second stopper 2024. In particular, the method comprises the following steps of,

the handle 2031 comprises a first side 20311, a second side 20312, a third side 20313, a fourth side 20314, a first protrusion 20315 and a fifth side 20316, which are connected in sequence, wherein the fifth side 20316 is further connected with the first side 20311. The second edge 20312 serves as the front end of the handle 2031. Fourth side 20314, fifth side 20316, and first protrusion 20315 form the end of handle 2031. The first side 20311 and the third side 20313 serve as the intermediate ends of the handle 2031. The middle end of the handle 2031 is connected to the front end of the handle 2031 and the end of the handle 2031, respectively.

A handle 2031 has a first protrusion 20315 formed at an intermediate position of the end thereof. Since the fourth side 20314, the fifth side 20316 and the first protrusion 20315 constitute the end of the handle 2031, and the fourth side 20314 and the fifth side 20316 are respectively located at both sides of the first protrusion 20315, the first protrusion 20315 is located at the middle position of the end of the handle.

To increase the movement stroke of the unlocker 2032, the first protrusion 20315 is inclined to the left (light-end) with respect to the end of the handle 2031. When the first protrusion 20315 is inclined to the left (light-end) with respect to the end of the handle 2031, the vertical distance between the first protrusion 20315 and the front end of the unlocker 2032 is D1. When the first protrusion 20315 is not inclined with respect to the end of the handle 2031, the vertical distance between the first protrusion 20315 and the front end of the lock release 2032 is D2. Wherein D2 is greater than D1. Since the movement stroke of the unlocking means 2032 sliding to the right (electric port end) is determined by the vertical distance between the first protrusion 20315 and the front end of the unlocking means 2032, and D2 is greater than D1, the first protrusion 20315 is inclined to the left (optical port end) with respect to the end of the handle 2031, increasing the movement stroke of the unlocking means 2032.

The first protrusion 20315 may have a trapezoidal structure without a bottom side or a trapezoidal structure with a bottom side. In particular, the method comprises the following steps of,

when the first protrusion 20315 is a trapezoid structure without a bottom edge, the first protrusion 20315 includes a sixth edge 203151, a seventh edge 203152, and an eighth edge 203153, the sixth edge 203151 and the eighth edge 203153 are respectively the waists of the trapezoid structure, and the seventh edge 203152 is the top edge of the trapezoid structure. Wherein, the fourth side 20314, the sixth side 203151, the seventh side 203152, the eighth side 203153 and the fifth side 20316 are connected in sequence.

When the first protrusion 20315 is a trapezoid structure having a bottom edge, the first protrusion 20315 includes a sixth edge 203151, a seventh edge 203152, an eighth edge 203153 and a ninth edge, the sixth edge 203151 and the eighth edge 203153 are respectively the waist of the trapezoid structure, the seventh edge 203152 is the top edge of the trapezoid structure, and the ninth edge is the bottom edge of the trapezoid structure. The fourth side 20314, the sixth side 203151, the seventh side 203152, the eighth side 203153 and the fifth side 20316 are sequentially connected, and two ends of the ninth side are respectively connected with the fourth side 20314 and the fifth side 20316.

The handle 2031 further comprises a U-shaped structural member. Since the handle 2031 includes a first side 20311, a second side 20312, and a third side 20313 in addition to the end of the handle 2031, the first side 20311, the second side 20312, and the third side 20313 form a U-shaped structural member.

The handle 2031 has its end placed in the storage groove 2021. Specifically, the fourth side 20314, the fifth side 20316 and the first protrusion 20315 of the handle 2031 are all disposed in the storage groove 2021. When the handle 2031 is not rotated, the first protrusion 20315 is disposed at the left side (the end of the light opening) of the storage groove 2021. When the handle 2031 is turned, the first protrusion 20315 is turned from the left side (end of the light) of the article-placing groove 2021 to the right side (end of the light) of the article-placing groove 2021.

The unlocking means 2032 has a second protrusion 20321 at the front end, a hollow 20322 in the middle, and an inclined structure 20323 at the end for sliding along the outer surface of the lower housing 202. In particular, the method comprises the following steps of,

the second protrusion 20321, contacting the first protrusion 20315, slides to the electrical port end when the first protrusion 20315 is pushed by the electrical port end to turn from the optical port end. Specifically, the second protrusion 20321 includes a first side 203211, a second side 203212, an inclined surface 203213, a third side 203214, a fourth side 203215, and a fifth side 203216. The first side 203211 is perpendicular to the outer surface of the unlocker 2032. A second side 203212 parallel to the outer surface of the unlocker 2032 and connected at the front end to the first side 203211. The inclined surface 203213 has a front end connected to the second side 203212. The third side 203214, which is connected to the end of the inclined surface 203213 at the front end, is parallel to the second side 203212 and slides along the outer surface 2032 of the lock release. A fourth side 203215, which is connected to the third side 203214 at its front end, is parallel to the first side 203211, and is connected to the front end of the lock release 2032. The fifth side 203216 has a front end connected to the end of the third side 203214 and a rear end connected to the front end of the first side 203211, parallel to the third side 203214, and connected to the outer surface of the lock release 2032. The inclined surface 203213 of the second protrusion 20321 is in contact with the first protrusion 20315, and when the first protrusion 20315 is turned from the optical port end to the electrical port end, the first protrusion 20315 pushes the inclined surface 203213 of the second protrusion 20321 to slide toward the electrical port end.

To increase the sliding distance of the second protrusion 20321 to the right, the end of the inclined surface 203213 is recessed more than the front end of the inclined surface 203213. The end of the inclined surface 203213 is more recessed relative to the front end of the inclined surface 203213, meaning that: the perpendicular distance between the end of the inclined surface 203213 and the first side surface 203211 is greater than the perpendicular distance between the front end of the inclined surface 203213 and the first side surface 203211. Because of the first protrusion 20315, it first contacts the front end of the inclined surface 203213, slides down the inclined surface 203213, and finally contacts the end of the inclined surface 203213. Therefore, in use, first, the first protrusion 20315 contacts the front end of the inclined surface 203213, and the first protrusion 20315 pushes the second protrusion to slide toward the electrical port end to the first position. As the first protrusion 20315 slides along the front end of the inclined surface 203213 to the end of the inclined surface 203213, the first protrusion 20315 is gradually pushed from the first position to the second position. The second position is where the first protrusion 20315 is in contact with the end of the inclined surface 203213, and the second position is closer to the electric port end than the first position.

The hollow 20322 is provided with a return spring 2033 therein. Specifically, the empty groove 20322 is provided with a third protrusion 203221 at one end. A third protrusion 203221 for inserting the return spring 2033 to connect the return spring 2033.

The inclined structure 20323 has a tip end recessed from a front end thereof for allowing the engaging member 2022 to be disengaged from the bayonet by sliding the lock release 2032. Specifically, the end of the inclined structure 20323 is more concave relative to the front end of the inclined structure 20323, which means that: the perpendicular distance between the end of the ramp structure 20323 relative to the end of the unlocker is greater than the perpendicular distance between the front end of the ramp structure 20323 relative to the end of the unlocker. In the using process, firstly, the tail end of the inclined structure 20323 is contacted with an elastic sheet of an upper computer; as the inclined structure 20323 slides to the right (at the electric port end), the surface of the inclined structure 20323 gradually contacts with the shrapnel of the upper computer, and the shrapnel of the upper computer is gradually jacked up; when the inclined structure 20323 slides to the right (at the electric port end) to be at the third position, the front end of the inclined structure 20323 contacts with the elastic sheet of the upper computer, and the elastic sheet of the upper computer is completely bounced off, so that the clamping component 2022 is separated from the bayonet of the upper computer, and the fixed connection between the optical module and the upper computer is released.

The storage slot 2021 is disposed at a position close to the optical port end on the outer surface of the lower housing 202. The storage slot 2021 is recessed relative to the outer surface of the lower housing 202. The end of the handle 2031 is arranged in the storage groove 2021. When the handle 2031 is not rotated, the tail end of the handle 2031 is positioned at the left side (the light opening end) of the article holding groove 2021; when the handle 2031 is turned, the end of the handle 2031 is turned from the left side (end of the light) to the right side (end of the electricity) of the storage groove 2021.

And the clamping part 2022 is matched with a bayonet of the upper computer to realize the fixed connection between the optical module and the upper computer. The shape of the clamping part 2022 is also triangular, the shape of the bayonet of the upper computer is triangular, and the included angle and the side length of the bayonet and the clamping part 2022 are completely matched. That is, the included angle of the engaging element 2022 is equal to the included angle of the bayonet, and the side length of the engaging element 2022 is smaller than the side length of the bayonet. When the side length of the bayonet is smaller than the side length of the engaging member 2022, the engaging member 2022 cannot be inserted into the bayonet, and the optical module cannot be connected to the upper computer. When the side length of the bayonet is equal to the side length of the engaging member 2022, the engaging member 2022 can be inserted into the bayonet, but the engaging member 2022 is easily worn because the both are just caught.

The first stopper 2023 is disposed in the hollow 20322 and is used to limit the return spring 2033.
