Connection to solve the problem that small pluggable transceiver and light modules are easy to fall off from the interface; for example, the cabinet can be used to connect small pluggable modules with electrical interfaces to the interface, solving the problem that small pluggable modules with electrical interfaces are easy to fall off from the interface; Similarly, the cabinet can also be used to connect storage modules to interfaces to solve the problem of storage modules easily falling off from interfaces. For ease of explanation, the following takes the connection between a small pluggable transceiver and optical module and an interface as an example. The type of optical module used in the cabinet does not have any impact on the structure of the cabinet.

In some embodiments, as shown in FIGS. 1 and 2 , the cabinet 1 includes a cabinet 10 and an optical module 20 . The optical module 20 includes a fixing part 21 and an unlocking part 22 .

The cabinet 10 has an interface 11, and a locking mechanism 111 is provided in the interface 11. The optical module 20 can be inserted into the interface 11, and the optical module 20 is fixed in the interface 11 through the locking mechanism 111 to prevent the optical module 20 from falling off the interface 11. Any device or structure that can satisfy the locking mechanism 111 meets the requirements of this case. For example, the locking mechanism 111 can be a spring device; for example, the locking mechanism 111 can also be a rotating device with a torsion spring. The locking mechanism 111 can be disposed at any position in the interface 11. For example, the locking mechanism 111 can be disposed on the upper surface of the interface 11; for example, the locking mechanism 111 can also be disposed on both sides of the interface 11. The locking mechanism 111 will be described in detail later and will not be described in detail here.

The optical module 20 includes a fixing part 21. The fixing part 21 includes a shell and a circuit board inside the shell. The specific structure of the fixing part 21 is not specifically limited here. According to the specific structure of the internal circuit, the shell of the fixing part 21 can be adjusted adaptively. , the circuit board is prevented from shaking inside the casing through structural design. The specific structure will be exemplarily described later. The fixed portion 21 is provided with a contact portion 211 that can contact the locking mechanism 111 , and the fixed portion 21 is provided with a guide surface 212 . The contact portion 211 can be understood as a structure that can be used to support or block the locking mechanism 111. Any structure that can contact the locking mechanism 111 meets the requirements of this case. For example, as shown in Figure 3, the contact portion 211 can be The groove 213 is used to contact the locking mechanism 111 to prevent the optical module 20 from falling off the interface 11 . For example, as shown in FIG. 4 , the contact portion 211 can be a bevel boss 214 , and the bevel boss 214 is used to contact the locking mechanism 111 to prevent the optical module 20 from falling off the interface 11 ; at the same time, the setting of the contact portion 211 The position should match the position where the locking mechanism 111 is set. For example, if the locking mechanism 111 is set on the upper surface of the interface 11, then the abutting portion 211 should be set on the upper surface of the fixing portion 21, so that the locking mechanism 111 is in contact with the abutting portion 211. The contact portions 211 are in contact with each other; for example, if the locking mechanism 111 is provided on both sides of the interface 11, the contact portions 211 should be provided on both sides of the fixing portion 21, so that the locking mechanisms 111 on both sides are respectively connected with the contact portions on both sides. The connecting portion 211 is in contact. The contact portion 211 will be described in detail later and will not be described in detail here.

The unlocking part 22 is movably connected to the fixing part 21 , and at least part of the unlocking part 22 can contact the guide surface 212 . The structure of the unlocking portion 22 is not specifically limited, as long as it meets the requirement that at least part of the unlocking portion 22 can contact the guide surface 212. For example, the unlocking portion 22 can be a long sheet with one end of the long sheet having a bent structure, such as As shown in FIG. 5 , the bent portion of the long sheet can be in contact with the guide surface 212 ; for example, the unlocking portion 22 can be a cylinder, and one end of the cylinder can be in contact with the guide surface 212 . The movable connection between the unlocking part 22 and the fixing part 21 can be understood as any device or structure that can enable the movable connection between the unlocking part 22 and the fixing part 21 , and the specific structure is not limited here. Exemplarily, the unlocking part 22 and the fixing part 21 are connected by a spring. Under the action of elastic force, the unlocking part 22 and the fixing part 21 can return to the initial state after relative movement. Exemplarily, the fixing part 21 is provided with a chute, and the unlocking part 22 A slider is provided on the part 22, and the unlocking part 22 and the fixed part 21 are movably connected by sliding the slider in the slide groove. Here, the unlocking part 22 and the fixed part 21 cannot return to the initial state after relative movement.

The fixing part 21 is provided with a guide surface 212, and at least part of the unlocking part 22 can be in contact with the guide surface 212. The guide surface 212 can be understood as any surface that can change the initial direction of movement. For example, the guide surface 212 can be an inclined surface, and the unlocking portion 22 moves at least partially on the inclined surface. The unlocking portion 22 is in contact with the guide surface 212; for example, the guide surface 212 can be It is a curved surface, and the unlocking portion 22 moves at least partially on the curved surface, and the unlocking portion 22 contacts the guide surface 212; at least part of the unlocking portion 22 moves along the guide surface 212 to unlock the locking mechanism 111. The unlocking part 22 is in the first position, as shown in Figure 6, and the locking mechanism 111 is in contact with the abutting part 211 to limit the movement of the optical module 20 away from the interface 11; as shown in Figure 7, in the second position , the unlocking part 22 deforms or displaces the locking mechanism 111, so that the locking mechanism 111 is separated from the contact part 211.

It should be noted that here, the unlocking part 22 can move between the first position and the second position along the guide surface 212 for unlocking, including two solutions. One is that the unlocking part 22 moves from the first position to the second position for unlocking. , the movement direction is the direction in which the optical module 20 is inserted into the interface 11 ; second, the unlocking part 22 moves from the first position to the second position for unlocking, and the movement direction is the direction in which the optical module 20 leaves the interface 11 . The structure of the unlocking part 22 and the principle of releasing the contact between the locking mechanism 111 and the contact part 211 will be exemplified below.

For example, the locking mechanism 111 is a rotation device with a torsion spring. The rotation device of the torsion spring is installed on the upper surface of the interface 11. Under the elastic force of the torsion spring, the rotation piece of the rotation device opens toward the inside of the interface. The contact part 211 is a bevel boss 214 structure, which is provided on the upper surface of the fixing part 21. The optical module 20 is inserted into the interface 11. During the insertion process, the rotating piece of the rotating device rotates under the action of the bevel boss 214. After the inclined surface boss 214 passes the rotating piece, one end of the rotating piece resists the inclined surface boss 214. The specific contact position is not specifically limited. The contact position can be a flat surface or an inclined surface with an inclination angle, which can meet the requirements of preventing light. The module 20 can be moved backward and detached from the interface 11. The surface where the rotating piece contacts the inclined boss 214 is the guide surface 212. The fixed part 21 is provided with a groove. The unlocking part 22 is a cylindrical structure, and a slider is provided on the cylinder. Located in the groove, the cylindrical structure can slide in the groove. The unlocking part 22 is in the first position at this moment. The unlocking part 22 is pushed toward the inside of the interface 11. The unlocking part 22 moves along the chute toward the inside of the interface 11. One end of the unlocking part 22 Move to the guide surface 212 of the inclined boss 214, contact the rotating piece, and separate the rotating piece from the guide surface 212, that is, the locking mechanism 111 is separated from the abutting portion 211. At this moment, the optical module 20 is unlocked. Pull out the optical module 20. Output interface 11.

For example, the locking mechanism 111 is a rotation device with a torsion spring. The rotation device of the torsion spring is installed on the side of the interface 11. Under the elastic force of the torsion spring, the rotation piece of the rotation device opens toward the inside of the interface. The contact portion 211 has a groove structure and is provided on the side of the fixing portion 21. When the optical module 20 is inserted into the interface 11, during the insertion process, the rotating piece of the rotating device fits against the fixing portion 21 under the action of the spring elastic force. On the side, the groove moves inward with the fixed part 21. When the rotating piece is in the groove position, one end of the rotating piece resists the groove. Similarly, the specific contact position is not limited. According to the structure of the groove, a corresponding step surface can be provided , or it can directly contact the inclined surface of the groove to prevent the optical module 20 from moving backward and falling off the interface 11 . The inner surface of the groove is provided with a guide surface 212 close to it, and the fixed part 21 is provided with a slide groove. The unlocking part 22 is a long arm structure, and the long arm structure can slide in the groove. The unlocking part 22 is in the first position at this moment, and the unlocking part 22 is in the first position. 22 is pulled toward the outside of the interface 11, and the unlocking portion 22 moves toward the outside of the interface 11 along the chute. One end of the unlocking portion 22 moves to the guide surface 212 of the groove and contacts the rotating piece 1121, causing the rotating piece 1121 to separate from the guide surface 212. That is, the locking mechanism 111 is separated from the contact portion 211. At this moment, the optical module 20 is completely unlocked, and the optical module 20 is pulled out of the interface 11.

An embodiment of the present invention provides a cabinet. The cabinet includes a cabinet and an optical module. The cabinet has an interface, and a locking mechanism is provided in the interface. The optical module can be inserted into the interface; wherein the optical module includes a fixing part and an unlocking part. The fixed part is provided with a contact part, which can contact with the locking mechanism, and the fixed part is provided with a guide surface; the unlocking part and the fixed part are movably connected, and at least part of the unlocking part can be in contact with the guide surface; the unlocking part can Move along the guide surface between the first position and the second position. At the first position, the locking mechanism contacts the abutment portion to limit the movement of the optical module away from the interface; at the second position, the unlocking portion makes the The locking mechanism is deformed or displaced to separate the locking mechanism from the abutting part. By arranging a locking mechanism in the interface, and providing a contact portion and an unlocking portion on the optical module, the optical module is locked in the interface by utilizing the cooperative relationship between the locking mechanism and the contact portion, and then the unlocking portion is in the first position and the second position. Movement between positions, using the cooperative relationship between the unlocking part and the locking mechanism, the locking mechanism is separated from the abutting part for unlocking, which facilitates the removal of the optical module from the interface, thereby solving the problem of loosening of the optical module and the cabinet interface, causing the optical module to easily The problem of detachment from the interface.

In some embodiments, one end of the unlocking portion 22 can abut against the guide surface 212 . Specifically, there are two situations. One is that the unlocking part 22 is always in contact with the guide surface 212. For example, the contact part 211 is an arc groove, and the arc surface in the arc groove is the guide surface 212. In the first position , one end of the unlocking part 22 is located at the bottom of the arc groove, and one end of the unlocking part 22 is in contact with the guide surface 212. When in the second position, the unlocking part 22 leaves the bottom of the arc groove and is still in the arc groove. On the arc surface in the groove, one end of the unlocking portion 22 is in contact with the guide surface 212 . Another method is to change the position of the unlocking part 22 through movement so that one end of the unlocking part 22 can contact the guide surface 212 . Specifically, it can be understood that in the first position, the locking mechanism 111 is in contact with the contact portion 211. At this moment, one end of the unlocking portion 22 is not in contact with the guide surface 212. When the unlocking portion 22 moves to the second position, the unlocking portion 22 One end can be in contact with the guide surface 212. For example, the contact portion 211 is a sloped boss 214, and the slope of the sloped boss 214 is a guide surface 212. In the first position, one end of the unlocking portion 22 is not on the sloped boss 214. At this time, one end of the unlocking portion 22 is not in contact with the guide surface. The surface 212 is in contact with each other. When in the second position, one end of the unlocking portion 22 moves to the inclined boss 214 . At this moment, one end of the unlocking portion 22 is in contact with the guide surface 212 .

In some embodiments, as shown in FIG. 4 , the unlocking part 22 moves from the first position to the second position for unlocking, and the movement direction is the direction in which the optical module 20 is inserted into the interface 11 , which can be understood as moving the unlocking part 22 toward the interface 11 . The interface 11 is pushed inside to unlock. For the unlocking method of pushing in, in order to facilitate the insertion and removal of the optical module 20, the optical module 20 also includes a first operating part 23. The first operating part 23 is connected to the fixing part 21. The first operating part 23 is connected to the fixed part 21. The portion 23 at least partially extends out of the interface 11 . Specifically, it can be understood that the unlocking part 22 is pushed into the interface 11, the end of the unlocking part 22 moves inward along the guide surface 212, and the end of the unlocking part 22 deforms or displaces the locking mechanism 111, and the locking mechanism 111 is separated from the contact portion 211, the optical module 20 is unlocked, and the operator pulls out the first operating portion 23 to separate the optical module 20 from the interface. The first operating part 23 can be any structure that is helpful for taking the optical module 20. At least part of it extends out of the interface 11 to facilitate the operator to insert and remove the optical module 20. The position and connection method of the first operating part 23 and the fixing part 21 are different. It can be specifically limited to meet the structural performance requirements and facilitate the plugging and unplugging of the optical module 20 . For example, the first operating part 23 can be a pull-tab structure, and one end of the pull-tab and the fixed part 21 are connected together by welding. For example, the first operating part 23 can be a flat plate structure, which is convenient for the operator to handle. At the same time, the flat plate structure can be used with the fixed part 21 during the production process. The fixing part 21 is an integrally formed structure.

In some embodiments, as shown in FIG. 8 , in order to facilitate the plugging and unplugging of the optical module 20 and to make the structure of the optical module 20 simpler and more compact, the optical module 20 also includes a second operating part 24 . The other end opposite to one end of the unlocking portion 22 is connected. In the first direction (the first direction is shown by the arrow in the figure), the distance between the first position and the other end is greater than the distance between the second position and the other end. One direction is parallel to the direction in which the optical module 20 leaves the interface 11 . Specifically, it can be understood that when the optical module 20 is inserted into the interface 11, the second operating part 24 is located outside the interface 11, and the distance between the first position and the position where the second operating part 24 and the unlocking part 22 are connected is greater than the distance between the second position and the position where the second operating part 24 is connected to the unlocking part 22. The distance between the positions where the second operating part 24 is connected to the unlocking part 22 , that is, the movement direction of the unlocking part 22 is the direction in which the optical module 20 moves away from the interface 11 , and the unlocking is performed by moving toward the outside of the interface 11 . The specific operation process has been exemplarily explained above and will not be repeated here. The second operating part 24 can be any structure that is helpful for taking the optical module 20. The position and connection method of the second operating part 24 and the unlocking part 22 are not specifically limited. It meets the structural performance requirements and facilitates the insertion and removal of the optical module 20. That’s it. For example, the second operating part 24 can be a pull-tab structure, and one end of the pull-tab and the unlocking part 22 are connected together by welding; for example, the second operating part 24 can be a long-arm structure, which is convenient for the operator to handle, and the long-arm structure can During the production process, the unlocking part 22 is an integrally formed structure.

In some embodiments, in order to facilitate the insertion of the optical module 20 into the interface 11, avoid the unlocking part 22 from colliding with the interface 11 during the insertion process, causing damage to the unlocking part 22, and at the same time improve the stability of the contact between the locking mechanism 111 and the abutting part 211. Properties, the fixing part 21 is provided with a groove 213, and part of the side wall of the groove 213 forms the abutment surface 2131. Specifically, it can be understood that the groove 213 provides a contact position for the locking mechanism 111, and part of the side wall of the groove 213 forms the contact surface 2131. The shape and specific size of the groove 213 are not limited. For example, The groove 213 can be a long groove structure, and the parts where the unlocking part 22 contacts the fixed part 21 can be arranged in the groove 213, effectively preventing the unlocking part 22 from protruding from the surface of the fixed part 21, and preventing the unlocking part 22 from interfacing with the interface. 11 collides, it should be noted that any position of the groove 213 that can provide contact with the locking mechanism 111 meets the requirements of this case, and the specific position is not limited. For example, the movement direction of the unlocking portion 22 is the direction in which the optical module 20 moves away from the interface 11, and is unlocked by moving toward the outside of the interface 11. The abutment surface 2131 is located at the end of the groove 213. In the first direction, the first The position is closer to the contact surface 2131 than the second position. The unlocking portion 22 contacts the locking mechanism 111 through the end position, causing the locking mechanism 111 to break away from the contact surface 2131 to unlock. For example, as shown in FIG. 9 , the abutment surface 2131 is located at the middle position of the groove 213 and is unlocked by moving toward the outside of the interface 11 . The abutment surface 2131 is located at the end of the groove 213 . In the first direction, the The second position is closer to the contact surface 2131 than the first position. The unlocking part 22 contacts the locking mechanism 111 through the middle position, causing the locking mechanism 111 to break away from the contact surface 2131 to unlock. The contact positions of the locking mechanism 111 and the abutment surface 2131 are different, and the contact positions of the unlocking part 22 and the locking mechanism 111 are different, both of which meet the unlocking requirements. In order to improve the stability of the contact between the locking mechanism 111 and the contact portion 211, the contact surface 2131 is set as a plane perpendicular to the first direction to reduce the possibility of the locking mechanism 111 slipping from the contact portion 211 and causing automatic unlocking. .

In some embodiments, as shown in conjunction with FIGS. 7 and 9 , the groove 213 includes a guide portion 2132 , the guide portion 2132 having a decreasing depth in the first direction to form a guide surface 212 . Specifically, it can be understood that the groove 213 can be used to provide abutment for the locking mechanism 111 and to guide the unlocking portion 22. The groove 213 can be provided on the upper surface of the fixing portion 21, or can be provided on the upper surface of the fixing portion 21. The side of the fixing part 21 needs to cooperate with the locking mechanism 111, and the specific installation position can be determined according to the actual situation. The inner surface of the groove 213 can be called the guide portion 2132. The depth of the guide portion 2132 decreases in the first direction. Any structure that meets the decreasing depth of the guide portion 2132 in the first direction meets the requirements of this case. For example, the guide portion 2132 is an inclined surface, the depth of which decreases in the first direction, and the rate of change of decrease here remains unchanged; for example, the guide portion 2132 is a curved surface, the depth of which decreases in the first direction, and the rate of change of decrease here keeps changing, there is When moving from the first position to the second position, the depth decreases slowly in the early stage and quickly in the later stage.

In the first position, the boss 221 is not in contact with the elastic piece 112 and is in contact with the guide surface 212. In the second position, one side of the boss 221 is in contact with the guide surface 212 and the other side is in contact with the elastic piece 112. contact, so that the elastic piece 112 contacts and disengages from the groove 213.

In some embodiments, as shown in Figures 10 and 11, Figure 11 is a partially enlarged schematic view of part A in Figure 10. In order to improve the convenience of operation of the optical module 20, after the unlocking part 22 moves from the first position to the second position, the unlocking part 22 can automatically return to the initial first position. The optical module 20 also includes an elastic device 25. The elastic device 25 connect the fixing part 21 and the unlocking part 22 respectively. Any device or structure that can enable the unlocking part 22 to automatically return to the initial first position meets the requirements. For example, the elastic device 25 can be a spring. Under the action of elastic force, the unlocking part 22 and the fixed part 21 move relative to each other. It can be restored to the initial state. The specific installation position of the spring is not limited. It can be adaptively adjusted according to the specific structure of the fixed part 21. For example, the end of the unlocking part 22 is connected to the fixed part 21 through a spring, and the unlocking part is stretched by stretching the spring. 22 moves from the first position to the second position. After the unlocking is completed, the unlocking portion 22 returns to the first position of the initial state from the second position under the tension of the tension spring; for example, the unlocking portion 22 A support platform 222 can be provided at the middle position. A spring is provided on the support platform 222 to connect with the fixed part 21. The unlocking part 22 moves from the first position to the second position by compressing the spring. After the unlocking is completed, the unlocking part 22 is compressed by the elastic force of the spring. Under the action, the unlocking part 22 returns to the first position of the initial state from the second position. By setting the elastic device 25, the unlocking part 22 automatically resets, which can effectively prevent the optical module 20 from being in the unlocked state for a long time, and it is inconvenient for the interface 11 to connect the optical module. fixed, while saving the manual reset operation process.

In some embodiments, as shown in FIG. 2 and FIG. 12 , in order to ensure that the optical module 20 is not easily detached when inserted into the interface 11 , while ensuring the compactness and stability of the structure of the optical module 20 itself, and preventing the internal structure of the optical module 20 from deflecting. When moving, the optical module 20 includes a circuit board 26, which is fixed inside the fixing portion 21; the contact portions 211 are symmetrically provided on both sides of the fixing portion 21, and the locking mechanisms 111 respectively contact the contact portions 211. It should be noted that the structure of the circuit board 26 is different, and the corresponding structure of the fixing part 21 will be changed.
