Description

Technical Field

[0001] The present invention belongs to the technical field of optical communication equipment, and in particular relates to an unlocking structure of an optical communication module and the optical communication module. Background Art

[0002] QSFP+SR optical communication modules are hot-swappable, meaning they can be connected and disconnected from equipment without turning off the power. Because optical communication modules are frequently plugged and unplugged during use, they are typically required to include a release mechanism to allow them to be easily removed from their mounting cage.

[0003] In order to better play the role of the hot-swappable performance of optical communication modules, it is necessary to continuously improve and optimize the unlocking structure for hot-swappable optoelectronic modules to achieve requirements such as fast unlocking, easy operation, and reliable and stable performance.

[0004] A Chinese utility model patent (publication number: CN205335531U) discloses a pull-ring unlocking device for an optical communication module. Its spring is accommodated in a receiving groove of the base, and the top end is covered by an upper cover to compress the blocking piece of the unlocking piece, thereby realizing the reciprocating movement of the pull ring.

[0005] However, during the actual installation process, before installing the upper cover, the spring is accommodated in the receiving groove of the base, with one end resting against the side wall of the receiving groove and the other end resting against the baffle, while the top is in a completely open state, and there is a lack of effective positioning between the unlocking piece and the base. The assembled semi-finished product is easily affected by external forces during subsequent transportation and production turnover, thereby causing parts to slip. Summary of the Invention

[0006] The purpose of the present invention is to provide an unlocking structure of an optical communication module and an optical communication module, which realizes the reset function after the pull ring is pulled by the mutual cooperation of an elastic member, a receiving groove, a limiting plate and a blocking plate, and utilizes the unlocking push plate to cover the two sides of the base and the blocking plate to be located in the receiving groove to realize the mutual positioning of the base and the pull ring, and then utilizes the limiting plate to cover the elastic member to prevent the elastic member from falling.

[0007] In order to achieve the above technical objectives, the technical solutions adopted by the present invention are as follows:

[0008] An unlocking structure for an optical communication module, comprising:

[0009] A base, wherein an upper end surface of the base is provided with a receiving groove along the length direction of the base;

[0010] an elastic member, wherein the elastic member is located in the accommodating groove;

[0011] A pull ring, comprising a handle and an unlocking push piece located on the side of the base, wherein the inner wall of the unlocking push piece is provided with a limiting piece and a blocking piece;

[0012] When the pull ring is installed on the base, the blocking piece is located in the accommodating groove, one end of the elastic member rests on the side wall of the accommodating groove close to the handle end, and the other end rests on the blocking piece, and the limiting piece is located on the side of the elastic member away from the base.

[0014] Such a structural design, by setting the position of the limiting piece in the accommodating groove, does not require a separate mechanism for accommodating the limiting piece, is simple to manufacture, and has strong practicality.

[0015] It is further defined that the accommodating groove is communicated with the outer side wall in the length direction of the base.

[0016] With this structural design, the receiving groove is connected to the side wall of the base, so that the blocking piece can be more conveniently placed in the receiving groove during installation, making installation more convenient.

[0018] When the pull ring is installed on the base, the secondary piece is located in the accommodating groove;

[0019] The base is provided with a guide groove corresponding to the secondary piece on a side of the accommodating groove away from the limiting piece.

[0020] This structural design can further reduce the risk of the elastic member falling out of the receiving groove by shielding the free end of the elastic member away from the limiting plate through the auxiliary plate.

[0021] At the same time, through the cooperation between the auxiliary piece and the guide groove, the guide groove not only avoids the movement of the auxiliary piece, but also guides the movement of the pull ring, reducing the freedom of movement of the pull ring in the vertical direction when it is pulled;

[0022] The notch is then used to provide a channel for the installation of the elastic member, thereby completing the installation of the elastic member.

[0023] It is further defined that the blocking piece is fixedly connected to the unlocking push piece via a limiting piece.

[0024] Such a structural design limits the upward tilting freedom of the end portion of the elastic member resting on the baffle through the fixed connection between the baffle and the limiting plate, further reducing the risk of the elastic member falling, and is highly practical.

[0025] It is further defined that the elastic member is a spring.

[0026] Such a structural design uses a spring as an elastic member to achieve the reset function after the pull ring is pulled. It has a simple structure, low cost and strong practicality.

[0038] Such a structural design completes the restriction of the pull ring through the mutual cooperation of the first limiting wall and the second limiting wall, has a simple structure, is easy to manufacture, and is highly practical.

[0039] It is further defined that an inclined block is fixedly provided on the upper end surface of the base away from the pull ring, and the inclined block is inclined from top to bottom in a direction away from the pull ring on the side close to the pull ring;

[0044] It is further defined that a PCD plate is detachably mounted on the base;

[0045] The base is provided with semicircular clamping columns vertically on both sides of the PCD plate, and semicircular grooves are opened on both sides of the PCD plate;

[0046] The base is further provided with limiting protrusions on both sides of the PCD plate, and the upper cover is provided with grooves at positions corresponding to the limiting protrusions;

[0068] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that in the drawings or descriptions, similar or identical parts are numbered the same. Implementations not shown or described in the drawings are forms known to those of ordinary skill in the art. In addition, directional terms mentioned in the embodiments, such as "upper," "lower," "top," "bottom," "left," "right," "front," and "back," are merely references to the directions in the drawings and are not intended to limit the scope of protection of the present invention.

[0069] like Figures 1 to 8 As shown, an unlocking structure of an optical communication module of the present invention includes:

[0070] The base 1 has an upper surface with a receiving groove 11 formed along the length direction of the base 1;

[0071] The elastic member 2 is located in the accommodating groove 11;

[0072] The pull ring 3 includes a handle 30 and an unlocking push piece 31 located on the side of the base 1. The inner wall of the unlocking push piece 31 is provided with a limiting piece 32 and a blocking piece 33;

[0073] When the pull ring 3 is installed on the base 1, the baffle 33 is located in the accommodating groove 11, one end of the elastic member 2 rests on the side wall of the accommodating groove 11 close to the handle 30, and the other end rests on the baffle 33, and the limiting plate 32 is located on the side of the elastic member 2 away from the base 1.

[0074] When the pull ring 3 is installed on the base 1 , the limiting piece 32 is located in the accommodating groove 11 , and the length of the limiting piece 32 is smaller than the length of the accommodating groove 11 .

[0075] In fact, according to actual conditions, a receiving mechanism for accommodating the limiting plate 32 can be provided on the side wall in the width direction of the base 1 along the length direction of the base 1. In this embodiment, by setting the position of the limiting plate 32 in the receiving groove 11, there is no need to set up a separate mechanism for accommodating the limiting plate 32, which is simple to manufacture and has strong practicality.

[0076] The receiving groove 11 is communicated with the outer side wall of the base 1 in the longitudinal direction.

[0077] In fact, the side walls of the receiving groove 11 and the base 1 in the width direction can also be closed according to actual conditions. In this embodiment, the receiving groove 11 is connected to the side walls of the base 1, so that the blocking piece 33 can be more conveniently placed in the receiving groove 11 during installation, making installation more convenient.

[0078] The inner wall of the unlocking push piece 31 is further provided with a secondary piece 34, which is arranged coplanar with the limiting piece 32, with a gap left between the secondary piece 34 and the limiting piece 32;

[0079] When the pull ring 3 is installed on the base 1, the secondary piece 34 is located in the accommodating groove 11;

[0080] The base 1 defines a guide groove 12 corresponding to the secondary piece 34 on a side of the accommodating groove 11 away from the limiting piece 32 .

[0081] The secondary piece 34 blocks the free end of the elastic member 2 away from the limiting piece 32, thereby further reducing the risk of the elastic member 2 being separated from the receiving groove 11.

[0082] At the same time, through the cooperation between the auxiliary piece 34 and the guide groove 12, the guide groove 12 not only avoids the movement of the auxiliary piece 34, but also guides the movement of the pull ring 3, reducing the freedom of movement of the pull ring 3 in the vertical direction when being pulled;

[0083] The notch is then used to provide a channel for the installation of the elastic member 2, thereby completing the installation of the elastic member 2.

[0084] The blocking piece 33 is fixedly connected to the unlocking push piece 31 via the limiting piece 32 .

[0085] In fact, according to actual conditions, the blocking piece 33 can also be directly fixedly connected to the unlocking push piece 31. This embodiment limits the freedom of the end of the elastic member 2 resting on the blocking piece 33 to tilt upward through the fixed connection between the blocking piece 33 and the limiting piece 32, thereby further reducing the risk of the elastic member 2 falling, and is more practical.

[0086] The elastic member 2 is a spring.

[0087] In fact, according to actual conditions, an elastic rubber column can also be selected as the elastic member 2. In this embodiment, a spring is used as the elastic member 2 to achieve the reset function after the pull ring 3 is pulled. It has a simple structure, low cost and strong practicality.

[0088] An optical communication module, comprising the unlocking structure of the optical communication module described above, wherein an upper cover 5 is mounted on a base 1, and a limiting mechanism is provided between the upper cover 5 and the pull ring 3;

[0089] The limiting mechanism is used to limit the maximum moving distance of the pull ring 3 moving in a direction away from the base 1 .

[0090] The maximum moving distance of the pull ring 3 is limited by a separately provided limiting mechanism, thereby avoiding the problem of failure of the elastic member 2 caused by excessive squeezing of the elastic member 2, and having strong practicality.

[0091] The limiting mechanism includes a first limiting wall 50 and a second limiting wall;

[0092] Both side walls of the upper cover 5 are provided with first sliding grooves 51;

[0093] The side wall of the base 1 is provided with a second sliding groove 13 at a position corresponding to the first sliding groove 51;

[0094] The first sliding groove 51 and the second sliding groove 13 together form a groove group for accommodating the unlocking push piece 31;

[0095] The unlocking push piece 31 is provided with a secondary groove 320 , and the limiting piece 32 is located in the secondary groove 320 ;

[0096] The side wall of the first sliding groove 51 close to one end of the handle 30 is a first limiting wall 50;

[0097] The side wall of the auxiliary groove 320 away from the end of the handle 30 is a second limiting wall;

[0098] The first limiting wall 50 is located on the movement path of the second limiting wall.

[0099] In fact, according to actual conditions, it is also possible to choose to set a limit block on the top of the unlocking push piece 31 and open a limit groove on the upper cover 5, so that the limit block is slidably installed in the limit groove to achieve the limitation of the maximum moving position. This embodiment completes the limitation of the pull ring 3 through the mutual cooperation of the first limit wall 50 and the second limit wall. It has a simple structure, is easy to manufacture, and is highly practical.

[0100] An inclined block 14 is fixedly provided on the upper end surface of the base 1 away from the pull ring 3. The inclined block 14 is inclined from top to bottom toward the direction away from the pull ring 3 on the side close to the pull ring 3.

[0101] An oblique groove 52 is formed at one end of the upper cover 5 away from the pull ring 3, and the oblique groove 52 is inclined from top to bottom away from the pull ring 3;

[0102] The upper cover 5 is provided with a mounting hole 53, and a countersunk bolt 4 is passed through the mounting hole 53;

[0103] A threaded hole 15 is defined on the base 1 , and the countersunk bolt 4 is screwed into the threaded hole 15 .

[0104] In fact, according to actual conditions, multiple bolts can be directly selected to install the upper cover 5 and the base 1. In this embodiment, the upper cover 5 and the base 1 are installed by the mutual cooperation of the inclined block 14, the inclined groove 52, and the countersunk bolt 4. The structure is simple, the installation is convenient, and the practicality is strong.

[0105] A PCD plate 6 is detachably mounted on the base 1;

[0106] The base 1 is provided with semicircular clamping columns 16 vertically on both sides of the PCD plate 6, and semicircular grooves 60 are opened on both sides of the PCD plate 6;

[0107] The base 1 is further provided with limiting protrusions 161 on both sides of the PCD plate 6, and the upper cover 5 is provided with grooves at positions corresponding to the limiting protrusions 161;

[0108] A plurality of top blocks 162 are disposed on opposite sides of the base 1 and the upper cover 5 .

[0109] In fact, according to actual conditions, multiple bolts can be directly used to screw the PCD plate 6 to the base 1. In this embodiment, the installation of the PCD plate 6 is completed by the mutual cooperation between the semicircular clamping column 16 and the semicircular groove 60, the limiting protrusion 161 and the groove and the top block 162. The structure is simple and the installation is convenient.

[0110] In this embodiment, during installation, the unlocking push piece 31 of the pull ring 3 is pulled to both sides and pushed in from the left side or bottom of the base 1 until the unlocking push piece 31 enters the second sliding groove 13, and the limiting piece 32, the blocking piece 33 and the auxiliary piece 34 all enter the accommodating groove 11, and the limiting piece 32 is pressed against the side wall of the accommodating groove 11 away from the handle 30;

[0111] Insert the elastic member 2 (spring) from the gap between the limiting piece 32 and the auxiliary piece 34, so that one end of the elastic member 2 rests on the blocking piece 33, and the other end rests on the side wall of the accommodating groove 11 near the end of the handle 30, and the limiting piece 32 and the auxiliary piece 34 block the upper side of the elastic member 2 (as shown in FIG. Figure 7 and Figure 8 shown);

[0112] The PCD plate 6 is placed on the base 1, supported by the top block 162 on the base 1, and the semicircular clamping columns 16 of the base 1 are clamped into the semicircular grooves 60 on both sides of the PCD plate 6. The limiting protrusions 161 then restrict the forward and backward movement of the PCD plate 6.

[0113] Insert the inclined groove 52 of the upper cover 5 into the inclined block 14 of the base 1, and make the upper cover 5 fit the base 1. At this time, the unlocking push piece 31 is located in the first sliding groove 51 of the upper cover 5. Then, pass the countersunk bolt 4 through the mounting hole 53 of the upper cover 5 and screw it into the threaded hole 15 of the base 1.

[0114] When in use, the handle 30 of the pull ring 3 is pulled away from the base 1, and the blocking piece 33 squeezes the elastic member 2, overcoming the prestress of the elastic member 2, and driving the unlocking push piece 31 to slide in the groove group surrounded by the first sliding groove 51 and the second sliding groove 13. During the sliding process, the auxiliary piece 34 slides from the accommodating groove 11 into the guide groove 12 until the second limiting wall of the pull ring 3 contacts the first limiting wall 50 of the upper cover 5;

[0115] After use, the pull on the pull ring 3 is released, and the pull ring 3 is reset under the action of the elastic member 2.
