Description

Technical Field

[0001] The present invention relates to the technical field of optical modules, and in particular to a side-push type installation and unloading mechanism and an installation method thereof. Background Art

[0002] With the commercialization of new technologies such as cloud computing and big data, new infrastructure, and national strategic deployments such as East-West Computing, data center traffic and bandwidth are growing exponentially. Currently, there is a great demand for optical modules in data centers, and the speed of optical modules is upgrading from 100G to 400G and 800G. In the field of optical transmission technology, the side-push installation and unloading mechanism has always been one of the mainstream mechanisms in optical modules. The side-push installation and unloading mechanism generally includes four parts: module base, module cover, pull ring, and spring. The assembly order is to first install the pull ring in the slide groove of the base, then install the spring between the pull ring and the module base, and then cover the module cover. In the existing side-push installation and unloading mechanism, there are three main ways to assemble the spring:

[0003] The first method, for example, in the patent application number CN201310114426.2, Figure 1 As shown, an opening is formed above the module base, a spring slot is provided for the spring to be directly placed downward, and the spring is arranged in the spring slot.

[0004] The second method, for example, in the patent application number CN201310191907.6, Figure 2 As shown, a slot for accommodating a spring is arranged on the side of the module housing, an opening is arranged on the side of the slide rod of the pull ring corresponding to the slot, and the spring is squeezed in through the opening.

[0005] The third method, for example, in the patent application number US12629650, Figure 3 As shown, grooves for accommodating springs are provided on the top, bottom or both sides of the module housing, the top or bottom surface of the pull ring is opened at the corresponding groove, and the spring is squeezed in from the opening. When assembling the module, the optoelectronic device must be installed first, and then the pull ring and the spring must be installed.

[0006] For the above three methods, the spring of the first method is very easy to jump out during the assembly process, and in the later maintenance stage of the optical module product, once the module cover is removed, the spring is also easy to jump out; after the spring of the second method is installed, the electromagnetic radiation generated by the optoelectronic components in the optical module is more likely to leak from the side opening of the slide rod, thereby reducing the electromagnetic compatibility of the optical module; the third method is to set a slot for accommodating the spring on the top, bottom or both sides of the module shell, and the top or bottom surface of the pull ring is opened at the corresponding slot, and the spring is squeezed in from the opening. When assembling the module, the optoelectronic device must be installed first, and then the pull ring and the spring must be installed. When the optical module is returned for production and the module cover is disassembled, the pull ring must be removed first, and the maintenance cost is high.

[0061] In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0062] Embodiment 1:

[0063] Embodiment 1 of the present invention provides a side-push type installation and unloading mechanism, such as Figure 4 As shown, it includes a housing base 1, a pull ring 2 and an elastic bracket 3.

[0064] like Figure 5-Figure 6 As shown, the pull ring 2 includes a pair of sliding plates 21 , and a stop arm 211 is provided on the sliding plate 21 .

[0065] Among them, Figure 5 As shown, the pull ring 2 of the embodiment of the present invention comprises a pair of sliding plates 21, and a stop arm 211 is provided on the sliding plate 21. It is worth noting that Figure 5-Figure 6 As shown, the direction of the stop arm 211 of the embodiment of the present invention can be set from top to bottom (see Figure 5 ), or you can set it from bottom to top (see Figure 6 In a specific application scenario, the pull ring 2 of the embodiment of the present invention includes a stack of sliding plates 21, and a stop arm 211 may be provided on the inner side of one sliding plate 21, but is not limited to it. Preferably, a stop arm 211 is provided on the inner side of each of the pair of sliding plates 21; in order to achieve better antimagnetic properties, the corresponding stop arm 211 and the sliding plate 21 are integrally stamped and formed, and are made into a shape as shown by a 180° folding process. Figure 5 however, as an optional implementation scheme of the embodiment of the present invention, the corresponding stop arm 211 can also be fixed to the inner surface of the sliding plate 21 by separate welding (optimally laser welding).

[0066] like Figure 7 As shown, the housing base 1 includes two side plates 11 , and a first accommodating cavity 111 is provided on the side plates 11 .

[0067] The stop arm 211 and the elastic bracket 3 are arranged in the first accommodating cavity 111, one side of the elastic bracket 3 abuts against the stop arm 211, and the other end of the elastic bracket 3 abuts against the side wall of the first accommodating cavity 111. In order to facilitate the abutment of the other end of the elastic bracket 3 (first transmission arm 31) against the side wall of the first accommodating cavity 111, in the embodiment of the present invention, a stop wall 1112 (see FIG. 111 ) is arranged where the first accommodating cavity 111 abuts against the other end of the elastic bracket 3 (first transmission arm 31). Fig.15 As shown in FIG. 1 , the stop wall 1112 is provided to make the connection between the elastic bracket 3 and the first accommodating cavity 111 more stable. Figure 8-Figure 9 As shown, the sliding plate 21 can slide back and forth relative to the two side plates 11; the elastic bracket 3 is arranged in the first accommodating cavity 111, and the stop arm 211 abuts against one side of the elastic bracket 3, and reciprocates in the first accommodating cavity 111 as the pull ring 2 is unlocked and reset.

[0068] like Figure 8-Figure 9 As shown, a first accommodating cavity 111 is provided on the outer wall of the side plate 11 of the housing seat 1 of the embodiment of the present invention, and a stop arm 211 is provided on the inner wall of the sliding plate 21 of the pull ring 2 in the vertical direction, and the pull ring 2 is connected to the housing seat 1 by sliding into the first accommodating cavity 111 through the stop arm 211; then the side wall of one side of the elastic bracket 3 is in contact with the stop arm 211. Figure 8 As shown, when the pull ring 2 is used to unlock, the pull ring 2 is pulled, and the stop arm 211 of the pull ring 2 applies force to the elastic bracket 3, and the elastic bracket 3 is compressed, thereby realizing the unlocking of the side-push type installation and unloading mechanism of the embodiment of the present invention. When it is necessary to inspect and repair the components inside the side-push type installation and unloading mechanism of the embodiment of the present invention, the pull ring 2 is used to compress the elastic bracket, so that the sliding plate 21 on the pull ring 2 is unlocked from the shell seat 1, and the compressed elastic bracket 3 is taken out. After the stop arm 211 loses the clamping effect of the elastic bracket 3, the pull ring 2 is taken out, thereby realizing the separation of the pull ring 2, the shell seat and the elastic bracket 3. Fig. 9As shown, during the installation process, first assemble the pull ring 2 with the shell seat 1, and ensure that the stop arm is set in the first accommodating cavity 111, then compress the elastic bracket 3, slide the elastic bracket 3 into the first accommodating cavity 111, so that the elastic bracket 3 abuts against the stop arm 211, and during the process of the elastic bracket 3 being set in the first accommodating cavity 111, the elastic bracket 3 is reset, and through the elastic action of the elastic bracket 3, it is ensured that the elastic bracket 3 always abuts against the stop arm 211, thereby ensuring that the pull ring 2 and the shell seat 1 are relatively fixed. It is worth noting that in order to facilitate the installation of the elastic bracket 3, an opening 1113 is provided above the first accommodating cavity of the embodiment of the present invention. When the elastic bracket 3 needs to be installed, the elastic bracket 3 is compressed, and then the elastic bracket 3 is slid into the first accommodating cavity 111 from the opening 1113, thereby realizing the installation of the elastic bracket 3; when it is necessary to disassemble, pull the pull ring 2, compress the elastic bracket 3, and then take the elastic bracket 3 out of the opening 1113, thereby realizing the disassembly of the elastic bracket 3.

[0069] The elastic bracket 3 of the present invention will not pop out after being installed in the first accommodating cavity 111, which can effectively avoid the risk of the spring popping out during the assembly process; the sliding plate 21 in the embodiment of the present invention is a closed setting. When the pull ring 2 is connected to the shell seat 1, the inner wall of the sliding plate 21 completely covers the first accommodating cavity 111, so that the partial structure on the pull ring 2 that cooperates with the elastic bracket 3 is in a fully closed state, with good electromagnetic compatibility performance, which can effectively avoid the problem of electromagnetic leakage; in addition, the structure inside the side-push installation and unloading mechanism of the embodiment of the present invention is relatively simple, easy to disassemble and install, and low maintenance cost.

[0070] In order to illustrate the complete solution of the present invention, the specific details of the present invention are explained in detail below. Figure 10-11 As shown, the elastic bracket 3 includes a first elastic arm 31 and a second elastic arm 32; the first elastic arm 31 and the second elastic arm 32 form a main deformation zone of a preset angle; wherein the second elastic arm 32 is used to abut against the stop arm 211 ， The first elastic arm 31 is used to abut against one side of the first accommodating cavity 111; in the unlocked state, the second elastic arm 31 is pushed toward the first elastic arm 31 by the stop arm 211 moving along with the pull ring 2, thereby storing the resilience required for the pull ring 2 to reset.

[0071] like Figure 10-11 As shown, the elastic bracket 3 includes a first elastic arm 31 and a second elastic arm 32; the first elastic arm 31 and the second elastic arm 32 form a main deformation zone of a preset angle. Specifically, the preset angle formed between the first elastic arm 31 and the second elastic arm 32 in the embodiment of the present invention is set according to actual conditions. The preset angle in the embodiment of the present invention (see Fig.11The angle α in the figure is the natural angle at which the first elastic arm 31 and the second elastic arm 32 are connected. When force is applied to the first elastic arm 31 and the second elastic arm 32, the preset angle of the main deformation zone between the first elastic arm 31 and the second elastic arm 32 will change, thereby changing the distance between the first elastic arm 31 and the second elastic arm 32. After the elastic bracket 3 of the embodiment of the present invention is arranged in the first accommodating cavity 111, the elastic bracket 3 is in a compressed state (at this time, the angle between the first elastic arm 31 and the second elastic arm 32 of the elastic bracket 3 is less than the angle α), thereby ensuring that the pull ring 2 and the shell seat 1 are relatively fixed through the elastic action of the elastic bracket 3.

[0072] like Figure 10-12 As shown, the end of the second elastic arm 32 that slides relative to the first accommodating cavity 111 is made with an arc-shaped abutting surface ( Figure 10-12 not marked in the figure).

[0073] like Figure 10-12 As shown, after the elastic bracket 3 is installed in the first accommodating cavity 111, the second elastic arm 32 abuts against the stop arm 211 on the pull ring 2. The arc-shaped abutting surface is arranged on the second elastic arm 32, so that the pull ring 2 can better abut against the second elastic arm 32 through the stop arm 211, and then the elastic bracket 3 can be more easily compressed by the stop arm 211 to avoid damage to the elastic bracket 3. It is worth noting that the elastic bracket 3 of the embodiment of the present invention includes a first elastic arm 31 and a second elastic arm 32. After the elastic bracket 3 is installed in the first accommodating cavity 111, the first elastic arm 31 always abuts against the side wall of the first accommodating cavity 111. During the process of axial compression or reset of the elastic bracket 3 along the shell seat 1, it can be considered that the first elastic arm 31 is always in a relatively static state with the side wall of the first accommodating cavity 111. Therefore, according to actual conditions, the embodiment of the present invention can set the first elastic arm 31 to be the same as the second elastic arm 32, and make one end of the first elastic arm 31 into an arc-shaped abutting surface (see Figure 10-11 As shown, not marked in the figure), so that the first elastic arm 31 can better abut against the side wall of the first accommodating cavity 111; the first elastic arm 31 may also not be processed. When the elastic bracket 3 is installed in the first accommodating cavity 111, it is only necessary to ensure that the first elastic arm 31 and the side wall of the first accommodating cavity 111 can always maintain a relatively static state (see Fig.12 shown).

[0074] like Figure 5 and Figure 7As shown, the stop arm 211 includes a connecting arm 2111 and a stop protrusion 2112, wherein the stop arm 211 and the sliding plate 21 are integrally stamped and formed, and the connecting arm 2111 is made by a 180° folding process, and the stop protrusion 2112 is formed by folding inward at the end of the connecting arm 2111. The first accommodating cavity 111 also includes a supporting platform 1111, and the supporting platform 1111 is used to support the connecting arm 2111, and the gap formed between the supporting platform 1111 and the first accommodating cavity 111 is used to accommodate the stop protrusion 2112.

[0075] like Figure 5 and Figure 7 As shown, the stop arm 211 of the embodiment of the present invention includes a connecting arm 2111 and a stop protrusion 2112. A bearing platform 1111 is also provided in the first accommodating cavity. When the pull ring 2 slides into the first accommodating cavity 111 through the stop arm 211, the connecting arm 2111 is placed on the bearing platform 1111. During the compression and reset process of the elastic bracket 3, the bearing platform 1111 remains stationary, and the connecting arm 2111 moves displacedly relative to the bearing platform 1111. It is worth noting that, in addition to the installation method of the stop arm 211 according to the embodiment of the present invention, Figure 5 In addition to setting the stop arm 211 in the manner of (the direction of the stop arm 211 can be set from top to bottom), the stop arm 211 can also be set as follows Figure 6 The stop arm can be set in a manner (the direction of the stop arm 211 can be set from bottom to top), and can be set specifically according to actual conditions, and can be but not limited to an integrated stamping method, and is made into the connecting arm 2111 through a 180° folding process, and the end of the connecting arm 2111 is folded inward to form the stop protrusion 2112. As it has been explained above, it will not be repeated here.

[0076] like Fig.13 As shown, the elastic bracket 3 includes a first elastic arm 31 and a second elastic arm 32; when the first elastic arm 31 and the second elastic arm 32 form a main deformation zone of a preset angle, during the unlocking process, the first transmission arm 31 arches toward one side of the first accommodating cavity 111 (see Fig.13 As shown), the second elastic arm 32 is arched toward one side of the support platform (see Fig.13 wherein, the remaining main body area after removing the bearing platform from the first accommodating cavity 111 constitutes the deformation and recovery space area of ​​the elastic bracket 3.

[0077] like Fig.10 and Fig.14 As shown, the elastic bracket 3 in the embodiment of the present invention is formed by bending a metal spring sheet; or, the elastic bracket 3 is formed by bending a cylindrical metal wire. Fig.10As shown, the elastic bracket 3 of the embodiment of the present invention can be formed by bending a metal spring sheet; Fig.14 As shown, the elastic bracket 3 of the embodiment of the present invention can also be formed by bending a circular metal wire. In a specific application scenario, the width of the metal spring or the diameter of the cylindrical metal wire in the embodiment of the present invention is adapted to the depth of the first accommodating cavity 111; wherein the depth of the first accommodating cavity 111 is the distance from the bottom surface of the first accommodating cavity 111 to the outer surface of the side plate 11.

[0078] like Fig.15 As shown, the inner side wall of the first accommodating cavity 111 is provided with a second accommodating cavity 112 extending axially along the shell base 1, and the stop arm 211 is accommodated in the second accommodating cavity 112. The second accommodating cavity 112 of the embodiment of the present invention can actually be considered as a part of the first accommodating cavity 111. In order to distinguish the setting positions of the connecting arm 2111, the stop protrusion 2112 and the elastic bracket 3, the embodiment of the present invention artificially divides a small area of ​​the first accommodating cavity 111 as the second accommodating cavity 112; it can be understood that after the connecting arm 2111, the stop arm 211, and the elastic bracket 3 are arranged in the first accommodating cavity 111, the space occupied by the connecting arm 2111 and the stop arm 211 in the first accommodating cavity 111 is the second accommodating cavity 112.

[0079] Next, other structures of the side-push type installation and unloading mechanism according to the embodiment of the present invention are described. Figure 15-16 As shown, the shell base 1 of the embodiment of the present invention further includes a bottom plate 12, and the two sides of the bottom plate 12 are respectively connected to one side of the side plate 11 to form a third accommodating cavity 13 for carrying the optoelectronic component 5. The optoelectronic component 5 of the embodiment of the present invention is arranged in the third accommodating cavity 13. By snapping the shell cover 4, the optoelectronic component 5 has been encapsulated in the third accommodating cavity 13. The assembly between the optoelectronic component 5 and other components in the installation and unloading mechanism (for example, the shell cover 4, the shell base 1, the pull ring 2 and the elastic bracket 3) is relatively independent, easy to disassemble and assemble, and has low maintenance cost. In order to clamp the optoelectronic component 5 in the third accommodating cavity 13, the shell cover 4 of the embodiment of the present invention is provided with a fourth accommodating cavity 43. When the shell cover 4 is snapped on the shell base 1, the fourth accommodating cavity 43 just matches the third accommodating cavity 13, so that the optoelectronic component 5 is arranged between the third accommodating cavity 13 and the fourth accommodating cavity 43.

[0080] In order to realize the connection between the pull ring 2, the shell cover 4 and the shell seat 1 of the embodiment of the present invention, as shown in FIG. Figure 17-Figure 18 As shown, the middle part of the outer wall of the side plate 11 of the embodiment of the present invention is provided with a first long groove 113 and a first limiting groove 114 along the axial direction of the shell seat 1, one end of the first long groove 113 is connected to the first accommodating cavity 111, and the other end of the first long groove 113 is provided with a first limiting groove 114;

[0081] A first limiting protrusion 212 is disposed at the rear of the sliding plate 21 . The first limiting protrusion 212 matches the first limiting groove 114 . The first limiting protrusion 212 is disposed in the first limiting groove 114 of the housing seat 1 .

[0082] In addition, the side-push type installation and unloading mechanism of the embodiment of the present invention further includes a shell cover 4, and the side of the shell cover 4 is provided with a second long groove 41 and a second limiting groove 42; one end of the second long groove 41 is provided with a second limiting groove 42. The first long groove 113 matches the second long groove 41; the tail of the sliding plate 21 is provided with a second limiting protrusion 213 in the opposite direction of the first limiting protrusion 212, and the second limiting protrusion 213 is arranged in the second limiting groove 42 of the shell cover 4, and the end surface of the sliding plate 21 is respectively abutted against the step 1141 and the side wall of the first limiting groove 114, and the inner wall of the sliding plate 21 is fitted on the inner wall of the first long groove 113 and the second long groove 41, so as to clamp the pull ring 2 between the shell cover 4 and the shell seat 1.

[0083] like Figure 17-Figure 18 As shown, the housing base 1 of the embodiment of the present invention is provided with a first long groove 113, and the housing cover 4 is provided with a second long groove 41. The first long groove 113 matches the second long groove 41. When the housing cover 4 is assembled with the housing base 1, the first long groove 113 is connected with the second long groove 41 to form a complete channel (see Figure 17-Figure 18 As shown), wherein the first long groove 113 is located on the shell base 1, and the second long groove 41 is located on the shell cover 4. When the pull ring 2, the shell cover 4 and the shell base 1 are connected, the inner wall of the sliding plate 21 of the pull ring 2 can just be set in the complete channel formed by the first long groove 113 and the second long groove 41. The shell base 1 is provided with a first limiting groove 114, and the shell cover 4 is provided with a second limiting groove 42. The first limiting groove 114 matches the second limiting groove 42. When the pull ring 2, the shell cover 4 and the shell base 1 are connected, the first limiting protrusion 212 at the tail of the sliding plate 21 can just be inserted into the first limiting groove 114, and the second limiting protrusion 213 can just be inserted into the second limiting groove 42. Then, the stop arm 211 on the pull ring 2 is fixed by the elastic bracket 3, and the end of the sliding plate 21 is abutted against the corresponding side walls of the first limiting groove 114 and the second limiting groove 42 by the elastic action of the elastic bracket 3, so that the pull ring 2, the shell base 1 and the shell cover 4 are connected. In addition, in order to facilitate unlocking, the length of the first limiting groove 114 in the embodiment of the present invention is longer than the first limiting protrusion 212, and the length of the second limiting groove 42 is longer than the second limiting protrusion 213. Figure 8As shown, the arrow indicates the direction of force applied to the pull ring 2. When unlocking and disassembling is required, the elastic bracket 3 is further compressed by pulling the pull ring 2, and the first limiting protrusion 212 on the sliding plate 21 moves along the first limiting groove 114, and the second limiting protrusion 213 moves along the second limiting groove 42, so that the end of the sliding plate 21 does not abut the corresponding side walls of the first limiting groove 114 and the second limiting groove 42. At this time, the shell cover 4 will not be subjected to the abutment force of the pull ring 2, and the shell cover 4 can be easily disassembled. After the shell cover 4 is disassembled, the elastic bracket 3 is compressed to the point where it can be taken out from the opening 1113 of the first accommodating cavity 111, the elastic bracket 3 is taken out, and finally the stop arm 211 on the pull ring 2 slides out from the opening 1113 of the first accommodating cavity 111, and the disassembly between the pull ring 2, the shell cover 4 and the shell seat 1 is completed. It is worth noting that the lengths of the first limiting groove 114, the second limiting groove 42, the first limiting protrusion 212 and the second limiting protrusion 213 of the embodiment of the present invention are set according to actual conditions. It is worth noting that the first limiting groove 114 and the second limiting groove 42 of the embodiment of the present invention are actually extended in the vertical direction, that is, the side wall of the side plate 11 of the housing 1 is grooved in the vertical direction, so that the first limiting protrusion 212 can be inserted into the first limiting groove 114, and the second limiting protrusion 213 can be inserted into the second limiting groove 42.

[0084] In order to better limit the sliding plate 21, as Fig. 9 As shown, in the embodiment of the present invention, the first limiting protrusion 212 is provided with an unlocking protrusion 214, the first limiting groove 114 is provided with a step 1141, the unlocking protrusion 214 is provided on the step 1141, and the end surface of the sliding plate 21 abuts against the step 1141 and the side wall of the first limiting groove 114, so as to limit the sliding plate 21. In the actual installation process of the pull ring 2, two stop surfaces 215 (see FIG. 215 ) are provided at the end of the sliding plate 21. Fig.18 As shown in FIG. 2 , the two stop surfaces 215 are symmetrically arranged with the unlocking protrusion 214 as the center. The stop surface 215 located at the bottom abuts against the side of the step 1141, and the stop surface 215 located at the top abuts against the locking surface 44 (see FIG. 2 ) arranged on the second long groove 41 of the shell cover 4. Figure 17-Figure 18 As shown in the figure, the locking surface 44 is actually the side wall of the second long groove 41) abuts against the pull ring 2 through the limiting effect of the stop surface 215 to achieve the installation of the pull ring 2 on the shell base 1. In addition, when unlocking, use your fingers to press the unlocking protrusions 214 on both sides (the unlocking protrusions 214 on both sides are symmetrically arranged, see Fig.18 ), then apply force to the pull ring in the opposite direction of installation (see Figure 8 or Fig.13In order to facilitate unlocking, the embodiment of the present invention preferably provides a pattern for increasing friction on the unlocking protrusion 214 (see Fig.18 , Fig.18 not marked in the figure).

[0085] like Fig.19 , one end of the first transmission arm 31 on the elastic bracket 3 of the embodiment of the present invention is elastically connected to one end of the second transmission arm 32 at a preset angle. When the other end of the first transmission arm 31 and the other end of the second transmission arm 32 are relatively sharp ends, the other end of the first transmission arm 31 and the other end of the second transmission arm 32 will be worn by pulling the pull ring 2 for a long time, thereby affecting the life of the elastic bracket 3. Based on this, the first transmission arm 31 of the embodiment of the present invention is provided with a first curling edge 33, and the second transmission arm 32 is provided with a second curling edge 34. The side wall of the first curling edge 33 abuts against the stop arm 211, and the side wall of the first curling edge 33 abuts against the side wall of the first accommodating cavity 111. The end of the elastic bracket 3 is arranged in an arc shape, so that the friction force of the elastic bracket 3 of the embodiment of the present invention is smaller during the compression process, thereby extending the life of the elastic bracket 3. In addition, in order to extend the service life of the elastic bracket 3, a smooth inflection point 35 (see FIG. 35 ) is provided at the connection between the first transmission arm 31 and the second transmission arm 32 of the embodiment of the present invention. Fig.19 As shown), the connection between the first transmission arm 31 and the second transmission arm 32 is smoother through the inflection point 35.

[0086] In order to better avoid electromagnetic leakage generated by the optoelectronic component 5 installed inside the side-push type installation and unloading mechanism of the embodiment of the present invention, as Fig. 20 The side push type installation and unloading mechanism includes a metal shielding cage 6, which is sleeved on the first accommodating cavity 111 of the installation and unloading mechanism to reduce electromagnetic radiation. The embodiment of the present invention provides a metal shielding cage 6 and utilizes the electromagnetic effect of the metal shielding cage 6 to effectively reduce the problem of electromagnetic leakage. In addition, in order to facilitate the disassembly and assembly of the side push type installation and unloading mechanism of the embodiment of the present invention, the pull ring 2 of the embodiment of the present invention is provided with a handle 22 (see Figure 5 and Figure 6 As shown in the figure, in order to apply force to the pull ring 2. When assembly is required, the stop arm 211 slides into the first accommodating cavity 111, and then the handle 22 on the pull ring 2 is pushed so that the stop arm 211 abuts against the second accommodating cavity 112, and then the elastic bracket 3 is installed in the first accommodating cavity 111; when unlocking is required, the pull ring 2 is pulled to unlock, and the entire assembly and unlocking process has been described above and will not be repeated here.

[0087] The elastic bracket 3 of the present invention will not pop out after being installed in the first accommodating cavity 111, which can effectively avoid the risk of the spring popping out during the assembly process; the sliding plate 21 in the embodiment of the present invention is a closed setting. When the pull ring 2 is connected to the shell seat 1, the inner wall of the sliding plate 21 completely covers the first accommodating cavity 111, so that the partial structure on the pull ring 2 that cooperates with the elastic bracket 3 is in a fully closed state, with good electromagnetic compatibility performance, which can effectively avoid the problem of electromagnetic leakage; in addition, the structure inside the side-push installation and unloading mechanism of the embodiment of the present invention is relatively simple, easy to disassemble and install, and low maintenance cost.

[0088] Embodiment 2:

[0089] Compared with the second embodiment of the present invention, the embodiment of the present invention further proposes a method for installing a side-push type unloading mechanism, such as Fig.21 As shown, including:

[0090] Step 201 : Slide the stop arm 211 into the first accommodating cavity 111 from the opening 1113 of the first accommodating cavity 111 .

[0091] In the assembly process of the embodiment of the present invention, the pull ring 2 and the housing base 1 are first assembled, and the stop arm 211 on the sliding plate 21 is slid into the first accommodating cavity 111 along the vertical opening 1113 of the first accommodating cavity 111 .

[0092] Step 202 : Push the pull ring 2 along the axial direction of the housing base 1 , so that the stop arm 211 abuts against the side wall of the first accommodating cavity 111 .

[0093] When the stop arm 211 slides into the first accommodating cavity 111, the handle 22 on the pull ring 2 is pushed, so that the stop arm 211 abuts against the side wall of the second accommodating cavity 112. At this time, the connecting arm 2111 on the stop arm 211 is just placed on the supporting platform 1111, and the stop protrusion 2112 on the stop arm 211 abuts against the side wall of the elastic bracket 3, thereby clamping the pull ring 2 on the shell seat.

[0094] Step 203 : squeeze the elastic bracket 3 inwards until the distance between the two ends of the elastic bracket 3 is smaller than the opening of the first accommodating cavity 111 , and then insert the elastic bracket 3 into the first accommodating cavity 111 .

[0095] like Figure 22-Figure 23As shown, it is a state change process diagram of the elastic bracket 3 during the assembly process. After the pull ring 2 is connected to the shell seat 1, the elastic bracket 3 is compressed so that the elastic bracket 3 can be smoothly inserted into the first accommodating cavity 111 from the vertical opening 1113 of the first accommodating cavity 111. After the elastic bracket 3 is inserted into the corresponding position of the first accommodating cavity 111, the elastic bracket 3 loses the compression force. At this time, the elastic bracket 3 rebounds, so that the other end of the first elastic arm 31 of the elastic bracket 3 abuts against the stop arm 211, and the other end of the second elastic arm 32 abuts against the side wall of the first accommodating cavity 111, thereby realizing the connection between the pull ring 2 and the shell seat 1.

During the assembly of the optoelectronic component 5, the pull ring 2 is first installed on the shell seat 1, and then the optoelectronic component 5 is installed in the third accommodating cavity 13 on the shell seat 1. Finally, the shell cover 4 is connected to the shell seat 1 to fix the optoelectronic component 5 in the third accommodating cavity 13.

[0099] Step 302: Place the shell cover 4 on the shell base 1, insert the first limiting protrusion 212 at the rear of the sliding plate 21 into the first limiting groove 114 of the shell cover 4, and abut the second limiting protrusion 213 at the rear of the sliding plate 21 against the step 1141 to complete the installation of the shell cover 4.

[0100] In the embodiment of the present invention, the shell cover 4 is connected to the shell seat 1 through the pull ring 2. After the pull ring 2 is connected to the shell seat 1, the first limiting protrusion 212 at the rear of the sliding plate 21 is inserted into the first limiting groove 114 of the shell cover 4, and the shell cover 4 is connected to the shell seat 1 through the action of the pull ring 2.

[0101] Step 303: After the shell cover 4 is installed, the metal shielding cage 6 is sleeved on the outermost part to install the unloading mechanism.

[0102] After the shell cover 4, the pull ring 2, the elastic bracket 3, the optoelectronic component 5 and the shell base 1 are assembled, the metal shielding cage 6 is sleeved on the outermost part to realize the installation of the installation and unloading mechanism; wherein, the optoelectronic component 5 generates electromagnetic signals during operation, and the metal shielding cage 6 has an electromagnetic shielding effect, which can further reduce the leakage of electromagnetic signals.
