Referring to FIGS. 3 and 4, an optical module provided by an embodiment of the present application adopts a self-unlocking manner, and has no special size requirements for the connection system, which can improve the applicability of the optical module and the connection system. Specifically, the optical module includes a handle 1, a housing 6, a latch 4, and a spindle 5; wherein, the handle 1, the unlocker 4, and the spindle 5 constitute an unlocking mechanism. The handle 1 is used to apply external force when unlocking, so as to realize the self-unlocking of the unlocker 4.

As shown in Figure 5, in order to realize the self-unlocking form, the unlocking device 4 includes a rotating part 41 with a through hole 44, a braking part 42 and a limiting part 43 located on both sides of the rotating part 41, and a braking part 42 and a limiting part. The movable groove 46 between the parts 43 and the locking part 45 at one end of the limiting part 43.

The self-unlocking form requires the unlocker 4 to rotate. In this embodiment, a through hole 44 is provided on the rotating part 41, and the rotating shaft 5 is located in the through hole 44. The rotating part 41 realizes the rotation of the unlocker 4; the locking part 45 is used to realize Lock and unlock with the tongue of the connection system. Wherein, the diameter of the rotating shaft 5 is smaller than the diameter of the through hole 44, so that the rotating shaft 5 is used as a rotating shaft to realize the rotation of the unlocking device 4.

In this embodiment, the rotating shaft 5 may have a cylindrical structure, and the material may be metal, such as rivets. The locking portion 45 is a hook-like structure, and the tip of the hook-like structure extends in the direction where the rotating portion 41 is located, which is opposite to the direction where the braking portion 42 is located. When the unlocking mechanism is locked with the connecting system, the hook-like structure hooks the corresponding parts of the connecting system to realize the locking and fixing.

The handle 1 can reciprocate in the movable groove 46; when the handle 1 moves, it drives the unlocker 4 to rotate, thereby realizing unlocking and locking. Therefore, in order to improve the unlocking effect of the unlocking device 4 by rotating, in this embodiment, a hollow portion 12 is provided on the handle 1, and the hollow portion 12 is located at the end of the handle 1 close to the unlocking device 4.

The braking portion 42 penetrates through the hollow portion 12. In some embodiments of the present application, the braking portion 42 may be exposed outside the hollow portion 12, or have a certain height, so as to prevent the height of the braking portion 42 from being too short and causing the handle 1 When the braking portion 42 is driven to move, the braking portion 42 falls off from the hollow portion 12, which affects the unlocking effect of the unlocking mechanism, and the stability is poor.

The front end of the handle 1 is located in the movable groove 46 and reciprocates in the movable groove 46, that is, the handle 1 is located between the limiting portion 43 and the braking portion 42, and the reciprocating movement of the handle 1 is controlled by the braking portion 42 and the limiting portion 43. To limit. The braking part 42 is used to drive the unlocker 4 to rotate according to the pulling force exerted by the handle 1 when unlocking, and the limit part 43 is used to drive the unlocker to rotate in the reverse direction according to the thrust exerted by the handle 1 when locking, and can also prevent the handle 1. The relative movement with the unlocker 4 affects the locked state. The position limiter 43 fixes the state of the handle 1 when it is not unlocked, which improves the stability of the unlocking mechanism.

In order to ensure the stability of the unlocking mechanism, in this embodiment, the bottom surface of the movable groove 46 is curved and protrudes toward the direction of the braking portion 41; the vertical distance from the braking portion 42 to the movable groove 46 is greater than that from the limiting portion 43 to the movable The vertical distance of the slot 46.

The bottom of the movable groove 46 is set as a curved surface, and the protruding direction is toward the braking portion 42, which prevents the bottom surface of the movable groove 46 from contacting the handle 1 when the unlocker 4 is rotating, and prevents the bottom of the movable groove 46 from exerting a pressing force on the handle 1 , So that the handle 1 has an upward movement trend. If the position of the handle 1 changes, it will affect the movement route of the handle 1, and then affect the unlocking effect. It can be seen that setting the bottom surface of the movable groove 46 as a curved surface can ensure the stability of the unlocking mechanism.

In order to make the unlocker 4 rotate smoothly and avoid interference with the handle 1, the vertical distance between the braking portion 42 and the movable groove 46 needs to be greater than the vertical distance between the limit portion 43 and the movable groove 46, that is, the distance between the movable groove 46 The depth on the side of the braking portion 42 is greater than the depth on the side of the limiting portion 43.

When the unlocker 4 rotates, the handle 1 reciprocates in the movable groove 46, and the brake part 42 moves in the hollow part 12. In order to ensure that there is sufficient space between the limit part 43 and the brake part 42 to achieve rotation, avoid The interference between the limiting portion 43 and the handle 1 requires that the opening width of the movable groove 46 is greater than the shortest distance between the hollow portion 12 and the front end of the handle 1. The shortest distance between the hollow part 12 and the handle 1 is the distance between the hollow part 12 and the end of the handle 1 close to the unlocker 4.

6(a) and 6(b), when the unlocking mechanism of the optical module provided by this embodiment is not unlocked, that is, when the locking portion 45 is locked with the tongue of the connecting system, the position of the unlocker 4 and the handle 1 The relationship is the initial state, that is, the front end of the handle 1 is located in the movable groove 46, and the front end of the handle 1 abuts the limiting portion 43, but does not abut the braking portion 42. The braking part 42 of the unlocking device 4 is located between the hollow parts 12 and is not in contact with the two ends of the hollow part 12 in the length direction. The limiting portion 43 can support the handle 1 to avoid moving in the direction of the limiting portion 43, thereby fixing the handle 1 to prevent the handle 1 from sliding and affecting the locking effect of the unlocking structure. When locked, the handle 1 contacts the limiting portion 43 and the locking portion 45 moves away from the housing 6.

As shown in Figure 7(a) and Figure 7(b), when the unlocking mechanism of the optical module provided by this embodiment is unlocked, that is, the front end of the hollow portion 12 on the handle 1 abuts against the braking portion 42, and the front end of the handle 1 does not abut压限位 43。 Pressure limit portion 43. The specific process of unlocking is as follows: the handle 1 moves to the left, and the vertical surface of the hollow part 12 close to the unlocking device 4, that is, the inner side surface of the handle 1 close to the unlocking device 4 gradually approaches the side wall of the braking portion 42. When the handle 1 continues to move to the left, the braking portion 42 is located at the right end of the hollow portion 12, the inner side of the handle 1 close to the unlocking device 4 is in close contact with the side wall of the braking portion 42, and the right end of the hollow portion 12 brakes The portion 42 exerts a force that moves to the left, so that the braking portion 42 tends to move to the left. Since the rotating part 41 under the braking part 42 can rotate around the rotating shaft 5, the unlocking device 4 is rotated counterclockwise, and the locking part 45 is lifted upward, that is, the locking part 45 rotates in the direction of the housing 6, so that the locking part 45 Disengage the connection system to achieve unlocking.

When it needs to be locked again, the handle 1 moves to the right, and the front end of the handle 1 applies force to the limit part 43, which causes the limit part 43 to rotate clockwise, which in turn drives the unlocker 4 to rotate clockwise to make The unlocker 4 returns to the initial state, and the locking portion 45 is locked with the tongue of the connection system.

In order to ensure the stability of the unlocking mechanism during unlocking and locking, the unlocking mechanism needs to be fixed on the housing 6 of the optical module, specifically, the handle 1 is installed on the housing 6. When the unlocking mechanism provided in this embodiment is unlocked, the locking portion 45 will retract into the optical module after rotating in the direction of the handle 1, to avoid interference between the unlocking mechanism and the connection system and affect the unlocking effect. It can be seen that the unlocking provided in this embodiment The mechanism can improve the applicability of the optical module and the connection system.

As shown in Figure 8, in order to realize the hiding of the locking portion 45, a hiding groove 65 is provided on the housing 6; when the handle 1 contacts the braking portion 42, the locking portion 45 moves toward the housing 6 and rotates into the hiding groove 65 Inside.

In order that the locking portion 45 can be retracted into the hidden groove 65 when unlocking, the length of the hidden groove 65 needs to be greater than or equal to the length of the unlocker 4 exposed to the unlocking mechanism. When unlocking, the unlocking device 4 rotates around the rotating shaft 5 so that the locking portion 45 of the unlocking device 4 rotates into the hidden groove 65, unlocking the locking portion 45 and the tongue of the connecting system, and unlocking the optical module and the connecting system.

As shown in Figure 9, after the unlocking mechanism of the optical module is installed with the housing 6 of the optical module, when the unlocking state is not unlocked, the locking portion 45 of the unlocking device 4 is exposed to achieve locking; when unlocking, because the unlocking device 4 is in The handle 1 realizes rotation under the driving of the handle 1, and the locking part 45 moves upward to release the lock with the tongue of the connection system, and retracts into the optical module, that is, the hidden groove 65, to avoid interference between the unlocking mechanism and the connection system, and is stable in use better.

In order to realize the stable installation of the unlocking mechanism, a first fixing groove 61 is provided on the housing 6, and the first fixing groove 61 is used for installing the handle 1. In order to achieve installation and ensure the stability of the unlocking mechanism of the optical module, the shape of the first fixing groove 61 needs to be the same as the shape of the handle 1, and the height of the side wall 66 of the first fixing groove 61 is equal to the thickness of the handle 1. , So that the first fixing slot 61 can fix the unlocking mechanism of the optical module, so as to avoid sliding and affect the use effect.

A side wall of the first fixing groove 61 is symmetrically provided with fixing holes 64, and the rotating shaft 5 is installed in the fixing hole 64 through the through hole 44. The fixing hole 64 is located at the end of the first fixing groove 61 close to the hidden groove 65. The first fixing groove 65 is in communication with the hidden groove 65, so that the unlocking mechanism formed after the unlocker 4 is installed on the handle 1 is installed at the same time into the first fixing groove. Slot 65 and hidden slot 65.

The rotating shaft 5 in the unlocking mechanism penetrates the unlocking device 4 and then is installed on the fixing hole 64 to fix the handle 1 carrying the unlocking device 4 in the first fixing slot 61 to improve the stability of the unlocking mechanism.

Since the unlocking device 4 is in a rotating state during unlocking, in order to prevent the unlocking device 4 from affecting the stability of the unlocking mechanism when the unlocking device 4 rotates, the relative position of the unlocking device 4 needs to be limited. Therefore, the optical module provided in this embodiment, as shown in FIG. 10, the unlocking mechanism further includes: a cover plate 2 located above the handle 1; an unlocker 4 is provided between the cover plate 2 and the handle 1; 5 The through hole 44 and the mounting groove 21 provided on the cover 2 are fixed on the cover 2, and the two ends of the rotating shaft 5 are fixed on the housing 6.

The handle 1 and the cover plate 2 are arranged in one upper and lower fit, and the unlocking device 4 is arranged between the cover plate 2 and the handle 1, which can increase the stability of the unlocking device 4 during rotation. When installing, it is necessary to ensure that when unlocking, the rotation direction of the unlocker 4 is the direction where the handle 1 is; when locking, the rotation direction of the unlocking device 4 is the direction where the cover 2 is located.

One end of the cover plate 2 is provided with a mounting groove 21, which is opposite to the hollow part 12, that is, a mounting groove 21 is provided on the side where the cover plate 2 and the handle 1 are attached; the mounting groove 21 is used for installing the unlocking device 4. In a normal state, the hollow portion 12 is in communication with the mounting groove 21, so that when the braking portion 42 of the unlocker 4 passes through the hollow portion 12, the unlocker 4 can ensure a vertical state and avoid affecting the effect of rotation.

Specifically, the rotating part 41 of the unlocking device 4 is located in the mounting slot 21, and the rotating shaft 5 penetrates the through hole 44 and the mounting slot 21 provided on the rotating part 41 and is fixed on the cover 2. When the unlocking mechanism is installed on the housing 6, the rotating shaft 5 passes through the cover plate 2, the mounting groove 21 and the through hole 44 one after another for fixing, and both ends of the rotating shaft 5 are located in the fixing holes 64.

When unlocking, the handle 1 moves in the opposite direction of the position where the unlocker 4 is located. Taking the state shown in Figure 10 as an example, the handle 1 moves to the left, and the hollow part 12 drives the brake part 42 to move to the left, so that the unlocker 4 The rotating part 41 rotates around the rotating shaft 5 in the mounting slot 21, and the locking part 45 rotates in the direction of the handle 1, ie, moves counterclockwise to release the lock with the tongue in the connection system, so that the optical module can be normally pulled out.

In order to improve the usability and convenience of the unlocking mechanism, in the optical module provided by this embodiment, the unlocking mechanism further includes: an elastic member 3; as shown in FIGS. 10 and 11, the elastic member 3 is located between the handle 1 and the housing 2. , When unlocked, the elastic member 3 is in a compressed state; when locked, the elastic member 3 is in an extended state. Two sides of the handle 1 are symmetrically provided with fixing seats 11; at the same time, two ends of the handle 1 are respectively provided with elastic members 3, and the elastic members 3 are on the same side as the fixing seat 11.

The two sides of the other end of the cover plate 2 are respectively provided with protrusions 22; the position of the cover plate 2 with the protrusions 22 is opposite to the direction in which the handle 1 is provided with the fixing seat 11. For example, if the fixing seat 11 is arranged at the front end of the handle 1, the protrusion 22 is arranged at the rear end of the cover plate 2.

The handle 1 is located between the two protrusions 22 so that the two protrusions 22 clamp the handle 1. In order to improve the stability, the distance between the two protrusions 22 is equal to the width of the handle 1, so that when the handle 1 and the cover plate 2 move relative to each other, the movement direction will not shift.

In order to enable the two protrusions 22 to hold the handle 1, to stabilize the state of the handle 1 in the moving process and avoid deviation, in this embodiment, one end of the protrusion 22 is higher than the exposed brake of the handle 1. On the surface on the side of the portion 42, the other end surface of the protrusion 22 is higher than the surface of the cover plate 2 on the side away from the handle 1.

The protrusion 22 and the cover 2 are not installed in alignment. The protrusion 22 needs to be exposed in the direction of contact with the handle 1, and the height of the protrusion 22 exposed to the handle 1 is greater than the height of the brake part 42 that needs to be exposed when the handle 1 is installed to avoid unlocking After the mechanism is installed in the optical module, other components of the optical module interfere with the braking portion 42, which affects the rotation of the braking portion 42, thereby affecting the unlocking and locking effects.

The handle 1 is clamped by two protrusions 22, and the position of the protrusion 22 is on the same side as the fixing seat 11. One end of each elastic member 3 is respectively fixed on the corresponding fixing seat 11, and the other end is respectively fixed on the corresponding protrusion 22. When the user pulls the handle 1 to move the handle 1 and the cover 2 in opposite directions, the protrusion 22 and the fixing seat 11 move in opposite directions, and the elastic member 3 is in a compressed state; when the user releases the handle 1, At this time, the elastic member 3 is in an extended state, so that the handle 1 and the cover plate 2 are restored to the initial state.

After stopping the application of external force to the handle 1, the elastic member 3 assumes an extended state and gradually returns to the original state. The stretching of the elastic member 3 drives the handle 1 to move to the right and returns to the original position, and the force of the handle 1 on the braking portion 42 disappears. However, a rightward pushing force is generated on the limiting portion 43, which causes the limiting portion 43 to move to the right. The unlocking device 4 rotates clockwise around the rotating shaft 5, and the locking portion 45 moves downward to realize the return of the unlocking device 4. The unlocking mechanism performs the locking operation again.

The protrusion 22 on the cover plate 2 is fitted into the groove 63 to fix the cover plate 2 in the second fixing groove 62 to improve the stability of the unlocking mechanism.

It can be seen from the above technical solutions that an optical module provided by an embodiment of the present application includes: a handle 1, a housing 6, an unlocker 4, and a rotating shaft 5. The rotating shaft 5 is located in the through hole 44 of the unlocking device 4, and the handle 1 can be unlocked. Reciprocating movement in the movable groove 46 of the unlocker 4; the handle 1 is mounted on the housing 6; when the handle 1 contacts the limiting portion 43 of the unlocker 4, the unlocker 4 uses the rotating portion 41 to rotate around the shaft 5 to lock the unlocker 4 The part 45 moves away from the housing 6 to achieve locking; when the handle 1 contacts the brake part 42 of the unlocker 4, the handle 1 drives the brake part 42 to move, so that the unlocker 4 uses the shaft 5 to rotate in another direction, so that The locking part 45 moves in the direction of the housing 6 to realize unlocking. The optical module provided by the present application adopts a self-unlocking method. When unlocking, the unlocker 4 realizes its own rotation, and the locking part 45 rotates in the direction of the housing 6, avoiding interference with the connection system, and has good stability; No special size requirements can improve the applicability of the optical module and the connection system.

It should be noted that in the above description of the working process of the optical module, the directional words such as "left", "right", "up", "down", "clockwise" and "counterclockwise" used are only based on The current state shown in Figure 6(a), Figure 6(b), Figure 7(a), Figure 7(b), Figure 10 and Figure 11 is only used to clearly illustrate the working process of the optical module. It does not limit the working process of the optical module. When the optical module is presented in other directions or angles, other solutions that can achieve or achieve the same or similar processes and effects as in this embodiment are also within the protection scope of this application.

Referring to FIGS. 3 and 12, another optical module provided by an embodiment of the present application adopts a self-unlocking method and has no special size requirements for the connection system, which can improve the applicability of the optical module and the connection system. Specifically, the optical module includes a handle 1, a housing 6, a latch 4, and a spindle 5; wherein, the handle 1, the unlocker 4, and the spindle 5 constitute an unlocking mechanism. The handle 1 is used to apply external force when unlocking, so as to realize the self-unlocking of the unlocker 4.

As shown in FIG. 13, in order to realize the self-unlocking form, another unlocker 4 includes a rotating part 41 with a through hole 44, a braking part 42 and a locking part 45 located on both sides of the rotating part 41. The self-unlocking form requires the unlocker 4 to rotate. In this embodiment, a through hole 44 is provided on the rotating part 41, and the rotating shaft 5 is located in the through hole 44. The rotating part 41 realizes the rotation of the unlocker 4; the locking part 45 is used to realize Lock and unlock with the tongue of the connection system. Wherein, the diameter of the rotating shaft 5 is smaller than the diameter of the through hole 44, so that the rotating shaft 5 is used as a rotating shaft to realize the rotation of the unlocking device 4.

In this embodiment, the rotating shaft 5 may have a cylindrical structure, and the material may be metal, such as rivets. The locking portion 45 is a hook-like structure, and the tip of the hook-like structure extends in the direction where the rotating portion 41 is located, which is opposite to the direction where the braking portion 42 is located. When the unlocking mechanism is locked with the connecting system, the hook-shaped structure hooks the tongue of the connecting system to realize the locking and fixing.

In order to ensure the stability of the unlocking device during the unlocking and locking process, in this embodiment, the rotation portion 41 and the braking portion 42 form a limiting groove 47; the bottom surface of the limiting groove 47 is curved and is away from the braking portion 42 The direction is sunken. The limiting groove 47 is surrounded by the upper surface of the rotating portion 41 and the side surface of the braking portion 42, and the bottom surface is set to a curved surface, that is, the top end of the limiting groove 47 extends in the direction of the lower surface of the rotating portion 41, so that the braking The distance between the top end of the part 42 and the top end of the limiting groove 47 is greater than the distance between the top end of the braking part 42 and the upper surface of the rotating part 41, so as to ensure that the unlocking device 4 rotates smoothly and avoid contact with the handle 1. Interference occurred.

The limiting groove 47 with a curved structure can also prevent the upper surface of the rotating part 41 from contacting the handle 1 when the unlocker 4 rotates, and avoids the upper surface of the rotating part 41 from exerting a pressing force on the handle 1, causing the handle 1 to move upward the trend of. If the position of the handle 1 changes, it will affect the movement route of the handle 1, and then affect the unlocking effect. It can be seen that the limiting slot 47 with a curved structure can ensure the stability of the unlocking mechanism.

When the unlocker 4 is locked and unlocked, the handle 1 exerts a force on the unlocker 4, and the movement of the handle 1 drives the rotation of the unlocker 4, so that the locking part 45 moves up and down to realize the locking part 45 and the connection system Locking and unlocking of the tongue. Therefore, in order to improve the unlocking effect of the unlocking device 4 by rotating, in this embodiment, a hollow portion 12 is provided on the handle 1, and the hollow portion 12 is located at the end of the handle 1 close to the unlocking device 4.

12, the braking portion 42 penetrates the hollow portion 12. In some embodiments of the present application, the braking portion 42 may be exposed outside the hollow portion 12, or have a certain height, so as to prevent the height of the braking portion 42 from being too short. As a result, when the handle 1 drives the braking portion 42 to move, the braking portion 42 falls off from the hollow portion 12, which affects the unlocking effect of the unlocking mechanism and has poor stability.

The brake part 42 can reciprocate in the hollow part 12, that is, the brake part 42 is located in the hollow part 12. The reciprocating motion of the brake part 42 is limited by the hollow part 12. For this reason, the handle 1 of the hollow part 42 is set The length in the moving direction is greater than or equal to the width of the braking portion 42, that is, the distance between the left side wall 121 and the right side wall 122 of the hollow portion 12 is greater than or equal to the distance between the two opposite side walls of the hollow portion 12. The left wall 121 is the end of the hollow part 12 that is far away from the unlocking device 4, and the right wall 122 is the end of the hollow part 12 that is close to the unlocking device 4.

The braking portion 42 is used to drive the unlocker 4 to rotate through the hollow portion 12 according to the force applied by the handle 1 when unlocking or locking. Specifically, when the braking portion 42 contacts the left side wall 121 of the hollow portion 12, that is, when the handle 1 moves to the right, a thrust is applied to the braking portion 42 to drive the rotation portion 41 of the unlocker 4 to rotate, causing the locking portion 45 to rotate. Move away from the housing 6 to achieve locking. When the braking portion 42 contacts the right side wall 122 of the hollow portion 12, that is, when the handle 1 moves to the left, a pulling force is applied to the braking portion 42 to drive the rotation portion 41 of the unlocker 4 to rotate, so that the locking portion 45 approaches the housing Move in the direction of the body 6 to achieve unlocking.

The braking portion 42 is restricted by the left side wall 121 of the hollow portion 12, which is equivalent to applying a rightward thrust to the braking portion 42 by the handle 1. When locking, the locking part 45 is locked with the tongue of the connecting system, and the braking part 42 is locked by the handle 1, so that both ends of the unlocking device 4 are fixed, so as to prevent the unlocking device 4 from rotating due to self-rotation. The locking part 45 is loose with the tongue, which affects the locking effect. Therefore, when the left side wall 121 presses against the braking portion 42, the unlocker 4 will not rotate by itself, so that the stability of the unlocking mechanism is better.

15(a) and 15(b), when the unlocking mechanism of another optical module provided by this embodiment is unlocked, that is, the right side wall 122 of the hollow portion 12 abuts the braking portion 42. The specific process of unlocking is as follows: the handle 1 is moved to the left, and the braking portion 42 gradually moves away from the left side wall 121 of the hollow portion 12 until it contacts the right side wall 122, and the right side wall 122 resists the braking portion 42 to the braking portion. 42 exerts a leftward pulling force, so that the braking part 42 tends to move leftward. Since the rotating part 41 under the braking part 42 can rotate around the rotating shaft 5, the unlocker 4 is rotated counterclockwise, and the locking part 45 is lifted upward, that is, the locking part 45 rotates in the direction of the housing 6, so that the locking part 45 is disconnected from the connection system to achieve unlocking.

When it needs to be locked again, the handle 1 is moved to the right, and the braking portion 42 gradually moves away from the right side wall 122 of the hollow portion 12 until it contacts the left side wall 121. The left side wall 121 resists the braking portion 42 and stops it. The moving part 42 exerts a rightward thrust to cause the braking part 42 to move to the right, thereby driving the unlocker 4 to rotate clockwise, the locking part 45 moves downwards, and the unlocking part 4 returns to the initial state, that is, the locking part 45 moves toward Move away from the housing 6 to realize the locking of the locking portion 45 with the tongue of the connecting system. Among them, the state of re-locking is as shown in Figs. 14(a) and 14(b).
