Description

Unlocking structure of pluggable module

Technical Field

The invention relates to an unlocking structure and an operation method applied to an electronic or optoelectronic module for communication.

background

Ports in communication equipment that transmit and receive signals to and from external lines, such as electrical cables, optical cables, etc., are typically formed of pluggable electronic or optoelectronic modules. These modules are conveniently installed and uninstalled at any time in the installation slots, or installation cages, of the device's communication unit in a direct plug-in and plug-out manner. One end (called tail end) of the module is inserted into the communication equipment and is in contact connection with an electronic interface inside the communication equipment; the other end of the module, referred to as the front end, forms a communications port that is configured on the panel for connection to various types of electrical or optical cables having corresponding standardized connectors, or alternatively, the cables to which the module is connected are of a unitary, permanent nature, with the modules removed and the cables removed altogether.

One core problem with the installation and removal of pluggable modules in communication devices is: the module is not only required to be stably connected with the electronic interface with dense connection points between the installed module and the equipment, but also required to be conveniently removed from the equipment when required, so that the problem of locking and unlocking of the pluggable module is solved.

Regarding the locking of pluggable modules in communication devices, the basic form of locking is agreed upon in the industry and is embodied in the relevant protocols and standards to achieve product-to-product matching and commonality between modules and devices. Figure 1 shows a basic form of locking of a pluggable module 1' in a device mounting cage 2 for one of the main types agreed in the industry and related protocols and standards. In this locking configuration, the cage 2 is provided with a spring 21 on each side thereof that is bent inwardly toward the rear end of the cage 2, and the pluggable module 1 'is provided with a locking step surface structure on each side thereof that faces the cage spring 21, such as the locking step surface 1711' illustrated in fig. 1. When the module 1 'is inserted into the installation cage 2 and the locking step surface 1711' of the module reaches the position of the installation cage elastic sheet 21, the elastic sheet 21 is released downwards to abut against the locking step surface 1711', so that the module 1' is locked in the equipment installation cage 2. The locking position corresponds to the situation that the module 1' is inserted into the innermost end of the installation cage 2, and the module cannot move back or be pulled out at the moment, so that the stable connection of the electronic interface between the module and the equipment is realized.

The above-mentioned agreed basic form of this locking, i.e. the basic form that determines the unlocking of the module 1': in order to make the module 1' itself have some kind of operation mechanism, when the module needs to be removed, the mechanism can lift up the elastic sheets 21 on both sides of the installation cage 2, so that the elastic sheets 21 are separated from the locking step surfaces 1711' on both sides of the housing of the module 1' as illustrated in fig. 1, thereby releasing the locking of the module, and the module can be pulled out from the device. In the existing unlocking mechanism of the module in the field of industry, for the module 1', a movable boss structure with a set inclined plane structure is mostly used, such as the unlocking boss 1211' shown in fig. 1, and the unlocking operation mechanism thereof enables the unlocking boss 1211' provided on the module 1' to move towards the elastic sheet 21 under the unlocking operation thereof, so that the inclined plane structure thereof is used for jacking up the installation cage elastic sheet 21, and the unlocking of the module 1' is completed.

Under the above unlocking basic form, the existing unlocking operation mechanisms applied in the industry are divided into two basic types: one is a rotary type pull ring design, the pull ring is fixed at the front end of the module housing and can rotate around the fixed point, the rotation drives an unlocking component with an unlocking boss 1211' at the tail end on two sides of the housing to horizontally move back and forth through a linkage structure, so as to realize the unlocking and resetting operation, and the typical structure can be seen in representative patent US9146366B 2; the other is a straight pull type pull ring design, an unlocking part of the pull ring which is horizontally pulled outwards and directly pulls the unlocking bosses 1211' at the tail ends of the two sides of the module shell to move towards the direction of the elastic sheet 21, the module is pulled out while the unlocking is finished, and then the unlocking part is automatically returned, namely reset by utilizing a spring structure arranged on the module, wherein the typical structure can be shown in representative patent CN 201310114326.2.

The biggest obstacle problem of the rotary pull ring in application is that the cable plugging and unplugging of the module cannot be realized: in this way, before unlocking the module, the cable connected to the module needs to be removed in advance, otherwise the rotation unlocking operation of the pull ring cannot be performed due to the blockage of the cable. This is inconvenient for the use of plugging and unplugging modules, and is completely impractical for pigtail modules of the integrated permanent connection nature, such as active fiber optic cables. One disadvantage of the straight pull tab approach is its lack of control over the unlocked state: since the unlocking and the extraction of the module are the same operation of pulling the tab outwards, the displacement of the module while it is unlocked has already taken place and the signal has then been interrupted, whether or not it is really necessary to extract the module. The disadvantage of this operation mechanism makes the straight pull ring method possibly cause a certain misoperation in operation, such as accidentally tearing the pull ring, or unlocking the module of the wrong line but not being able to be retrieved, and the line being interrupted immediately. Meanwhile, the straight pull ring mode is difficult to reset in place, namely after the unlocking action is operated, the module is restored to the locking state from the unlocking state under the condition that the module is not pulled out, and the work of the circuit is not influenced. The root cause of these problems with the straight pull mode is the lack of corresponding control of the unlocked state and its steps in the operating mode. For the rotary pull ring method, the cable needs to be removed before unlocking, so the rotary pull ring method does not have the function of in-place resetting.

Detailed Description

Some specific embodiments of the invention will be described in detail below, by way of example and not by way of limitation, with reference to the accompanying drawings. The same reference numbers in the drawings identify the same or similar elements or components. The figures are to be understood as schematic and are not necessarily drawn to scale.

One embodiment of the present invention is shown in fig. 2A and 2B. Fig. 2A is an assembly and disassembly schematic diagram of the pluggable module 1NA of the present invention, and its components include: the locking device comprises a push-pull handle 11A, an unlocking sheet 12N, a shell base 13N, a shell cover plate 14, a rotating block 15N, a rotating pin 101, a rotating block working spring 102, an unlocking sheet return spring 103, a module circuit board 104 and a fastening screw 105. Except that, other elements mounted inside the module case are omitted in this schematic view. Fig. 2B is a schematic diagram illustrating a complete appearance of the pluggable module 1NA of fig. 2A after the elements are assembled together, which is in an initial state. It should be noted that, in the present description, for some components or constituent structures which are the same or mirror images and are symmetrically distributed in the structures of the embodiments, only one of the representative units is numbered in each schematic diagram, and the reference to the number does not particularly distinguish the components or constituent structures which are the same or mirror images and are referred to unless otherwise indicated.

The detailed structure of the push-pull handle 11A of the pluggable module 1NA of the present invention is shown in fig. 3. It includes pivot 111, reset border 112 and spacing post 113 that handle body link both sides medial surface respectively set up. The limiting post 113 is a cylinder. The reset edge 112 is formed by the outline of the outer edge of the handle body connecting end on both sides as shown in the figure. The portion of the handle body that is bent at 45 ° is a handle contact 114L, and the bent area is designed to allow the handle contact 114L to be adapted to push and pull the handle 11A. The annular recessed region 115 shown on the stem body is here a color-coded region for representing the optical wavelength operating parameters of the optoelectronic module, the color-coding being specified by the relevant standards.

Fig. 4 shows a detailed structure of the unlocking piece 12N of the pluggable module 1NA of the present invention. The module is an H-shaped structure body and comprises two unlocking arms 121N which are respectively positioned at two sides of a module shell and are in a longitudinal elongated structure, and a transverse connecting part 122 which connects the unlocking arms 121N at the two sides into a whole. The unlocking piece 12N is integrally a sheet-like structure, is attached to the surface of the housing of the module 1NA, and can slide back and forth in the horizontal and longitudinal directions relative to the surface of the housing. Wherein the portion of the unlocking arm 121N facing the tail end of the module 1NA, i.e. the tail end of the unlocking arm 121N, is an unlocking end, which includes an unlocking front 1211, where the unlocking front 1211 is an edge of a general flat plate surface structure; the portion of the unlocking arm 121N facing the front end of the module 1NA, i.e., the front end of the unlocking arm 121N, is a connection and control end, and includes a shaft connection hole 1212, a rectangular reset abdicating hole 1213, a rectangular blocking hole 1214N, a semi-closed rotation abdicating hole 1215, and a first limiting projection 1216 located at the intersection of the upper end boundary of the semi-closed rotation abdicating hole 1215 and the front end edge of the unlocking arm 121N. Further, between the front and rear ends of the lock release arm 121N, i.e., in the middle of the lock release arm 121N, there are provided a bent structure 1217 and a lock release spring mounting square hole 1218 which are arranged in the horizontal longitudinal direction, wherein the bent structure 1217 is located further to the front end side of the lock release arm 121N than the return spring mounting square hole 1218. Fig. 5 is an enlarged view of the semi-closed rotation relief hole 1215 of fig. 4 and the first stopper protrusion 1216 having its upper boundary at the above-mentioned edge.

Here, the shaft connecting hole 1212 of the unlocking piece 12N is used to connect with the shaft 111 of the aforementioned push-pull handle 11A. After connection, the push-pull handle 11A can rotate relative to the unlocking piece 12N and can push and pull the unlocking piece to move in the horizontal direction. The semi-closed rotation abdicating hole 1215 of the unlocking piece 12N corresponds to the aforementioned limit post 113 of the push-pull handle 11A. After the push-pull handle 11A and the unlocking piece 12N are connected to the rotating shaft connecting hole 1212 of the unlocking piece 12N through the rotating shaft 111 of the push-pull handle 11A, the limiting post 113 of the push-pull handle 11A is located in the semi-closed rotation abdicating hole 1215 of the unlocking piece 12N. The semi-enclosed rotation abdicating hole 1215 is designed to allow the push-pull handle 11A to rotate upward from the horizontal position relative to the unlocking tab 12N, but not downward, through the restriction of its restraining post 113 in the abdicating hole, in the operational orientation of the module 1NA shown in fig. 2B. Meanwhile, the first limiting protrusion 1216 arranged at the edge of the upper end boundary of the semi-closed rotation abdicating hole 1215 enables the push-pull handle 11A to rotate upwards under the action of manual force, and after the limiting column 113 overcomes and crosses the first limiting protrusion 1216, the handle will not fall back to the horizontal initial position, but can stay at an angle after the limiting column 113 crosses the protrusion, so that the module can be conveniently plugged and unplugged.

The housing base 13N and housing cover 14 of the module are the main bodies that mount the various internal components of the module, including the module circuit board 104, and carry the various mechanical features and other components of the module. For convenience of illustration, fig. 6 shows a case where the housing base 13N and the housing cover 14 of the pluggable module 1NA of the present invention are connected by the fastening screws 105 to form a complete housing surface of the module 1 NA. The surface has a first combined recess space 171 for engaging the unlocking end of the unlocking arm 121N with the middle region, and a second combined recess space 172N for engaging the control end of the unlocking arm 121N, at portions on both sides of the module case.

The first combination groove space 171 limits the upper and lower edges of the elongated structure of the unlocking arm 121N, so that the unlocking arm 121N can only move horizontally in the front-back direction (horizontal and longitudinal direction) along the surface of the housing of the module 1 NA. Specifically, the first combined groove space 171 on both sides of the housing surface of the pluggable module 1NA of the present invention is provided with an upper step surface 1713 and a lower step surface 1714 which are coplanar in the upper and lower edge areas along the longitudinal length of the elongated structure of the unlocking arm 121N, wherein the upper step surface 1713 is located on the housing base 13N, and the lower step surface 1714 is located on the housing cover 14. The portion of the unlocking arm 121N located in the first combining recess space 171 is in contact with only the upper side step surface 1713 and the lower side step surface 1714, whereby the frictional resistance between the unlocking arm 121N and the housing surface of the module 1NA in the unlocking and resetting operation of the module of the present invention can be reduced. The upper side step 1713 and the lower side step 1714 are configured as slightly sloped surfaces at the end region extending from the rear end of the module housing, and are connected to form the same sloped surface in a small limited region at the extreme end of the slightly sloped surfaces. Meanwhile, the upper side step surface 1713 and the lower side step surface 1714 slightly form the groove edge where the end of the inclined surface is positioned, and a locking step surface 1711 is formed, where the module 1NA arranged in the first combined groove space 171 and the mounting cage elastic piece 21 act with each other. The locking step surface 1711 is also formed by two parts of the housing base 13N and the housing cover 14, and a specific groove space 1712 is formed by recessing the middle region of the locking step surface 1711 to the module tail end side. Unlike the prior art in which the groove space is used to accommodate the unlocking boss 1211' (see fig. 1), the groove space 1712 provided in the present invention is designed to reduce the effective acting width between the cage spring 21 and the locking step surface 1711, so that the unlocking front edge 1211 of the unlocking arm 121N can more easily lift up the cage spring 21 compared to the acting width of the complete cage spring 21, thereby completing the unlocking operation of the module.

The upper side step surface 1713/lower side step surface 1714 are designed to be a micro-inclined surface area on the side of the tail end of the module housing, due to the contracted limit of the relevant protocols and standards in the industry on the overall width dimension of the module 1NA housing. Under this convention, the outer surface of the lock release arm 121N must not be higher than the housing surface of the module 1NA formed by the housing base 13N and the housing cover 14 (i.e., the outer surface of the lock release arm 121N must not protrude beyond the housing surface of the module 1 NA), except at the position of the locking step surface 1711 of the housing that interacts with the mounting cage spring 21, which is allowed to be higher than a partial limit or less. Thus, in order to ensure that the unlocking front edge 1211 performs the unlocking sufficiently, i.e. to ensure that the mounting cage leaf spring 21 is completely separated from the locking step surface 1711 when being jacked up by the unlocking front edge 1211, a limited slightly-raised inclined surface is provided within the limited area of the end section of the first combined groove space 171 to which the unlocking front edge 1211 moves when being matched with the unlocking arm 121N to perform the unlocking operation, so that when the unlocking front edge 1211 reaches the position of the locking step surface 1711, the tip of the unlocking front edge 1211 is raised by the slightly-raised inclined surface to be higher than the upper edge surface (i.e. the shell surface) of the locking step surface 1711, thereby ensuring that the mounting cage leaf spring 21 can completely move out of the locking step surface 1711, and ensuring that the separation and unlocking effects of the mounting cage leaf spring and the mounting cage.

Further, in the first combining groove space 171, there are further provided a vertical mounting groove 1715 that allows passage of a bent structure 1217 on the unlocking arm 121N, and a horizontal longitudinal housing groove 1716 that houses the bent structure 1217 and the unlocking blade return spring 103, as shown in fig. 6. In this embodiment, the vertical mounting groove 1715 and the horizontal longitudinal receiving groove 1716 are both located on the housing base 13N. One end of the vertical mounting groove 1715 is open to the bottom surface of the housing base 13N, and the other end is connected to the horizontal longitudinal accommodating groove 1716; the inner wall surface of the horizontal longitudinal housing groove 1716 on the module front end side is a set positioning surface 1717, and the positioning surface 1717 abuts against the bent structure 1217 of the unlocking arm 121N to determine the final position to which the unlocking piece 12N can move in the module 1NA housing in the front end direction.

The second combined groove space 172N of the present invention mainly includes two setting areas, one is a turning block mounting groove 1721N for providing a movement space of the turning block 15N, and the other is a handle limiting groove 1722 for controlling a movement track of the push-pull handle 11A under the limitation of the limiting post 113. In this embodiment, the second combination groove spaces 172N are each formed by the housing base 13N. Wherein, a vertical rotation pin mounting shaft hole 1723 is provided in the rotation block mounting groove 1721N for inserting the rotation pin 101. In the structure of the present embodiment, the rotation pin mounting shaft hole 1723 needs to be punched from the side where the housing base 13N and the housing cover 14 are connected to each other, so as to form a hole structure penetrating vertically, depending on the limitations of the processing process. When the cover plate 14 is assembled with the base 13N, the cover plate 14 blocks the lower end opening of the rotation pin mounting shaft hole 1723, and the rotation pin 101 and the rotation pin mounting shaft hole 1723 are installed in a tight fit manner, so that the rotation pin 101 does not fall off during operation when the rotation pin 101 is inserted into the rotation pin mounting shaft hole 1723. A horizontal transverse receiving hole 1724 is further formed in the rotating block mounting groove 1721N for receiving the rotating block working spring 102. The arrangement of the handle stopper groove 1722 will be described in detail later with reference to the movement and operation of the push-pull handle 11A. Here, in particular, a second limiting protrusion 1725 is disposed at a position of an upper edge boundary of the handle limiting groove 1722 corresponding to the position of the limiting column 113 of the push-pull handle 11A in the initial horizontal state (see fig. 13A), and a partial enlarged structure thereof is shown in fig. 7. The second limiting protrusion 1725 is disposed in the handle limiting groove 1722, so that the push-pull handle 11A of the present invention is stable at its initial position, for example, when the module is installed in an equipment installation cage, and is in a locked normal working state, and the handle will not bounce or vibrate due to external vibration and other environmental factors, thereby generating noise.

The rotating block 15N in the invention is a key component for determining the unlocking working mechanism and the design of related quantitative parameters. The basic structural form of the turning block is shown as a representative structure 15' in fig. 8, which can be described as a "coaxial series" conjoined turning structure. As an example, the representative coaxial serial conjoined rotating structure 15 'includes an acting portion 151' and a deactivating portion 152', the acting portion 151' and the deactivating portion 152 'are distributed in the same radial direction and rotate around a common rotating shaft 101', and are connected as an interactive whole, and at any time, one of them rotates or rotates to a certain angle, and the other rotates or rotates to the same angle; the acting portion 151' and the deactivating portion 152' are spatially separated in the radial direction of the rotating shaft 101' by a distance that is set to a value such that no structural interference or collision occurs between the third party acting objects acting on the acting portion 151' and the deactivating portion 152', respectively. That is, the acting portion 151' and the deactivating portion 152' rotate about the same rotational axis 101' in a radially spaced apart manner, while forming an interacting entity therebetween and having a structural interaction with their respective objects of action. The radial distances of the operating points of the operating part 151' and the deactivating part 152' from the axis of the rotating shaft 101' are denoted by r1 and r2, respectively, and it can be seen that the ratio of the rotational displacement widths of the operating points of the operating part 151' and the deactivating part 152' about the rotating shaft 101' is equal to the ratio of the radial distances from the axis of the rotating shaft 101', that is, r1/r 2. In general, the acting section 151' and the deactivating section 152' may be located on the same side of the rotating shaft 101' or on opposite sides (i.e., on the same diameter), and the ratio r1/r2 (under the symbol) may have any desired value other than + 1. In addition, under the general principle, the coaxial series connection conjoined rotating structure can simultaneously comprise a plurality of action parts and/or deactivation parts, and the relevant corresponding relation is formed between any action part and the corresponding deactivation part.

The specific structure of the coaxial series connected rotating structure 15' in this embodiment is a rotating block 15N shown in fig. 9. The rotating block 15N comprises a blocking protrusion 151 and a reset protrusion 152N, which are respectively corresponding to the acting portion 151' and the deactivating portion 152' of the coaxial series connected rotating structure 15', which are located on the same radial side of the rotating shaft, wherein the reset protrusion 152N is located at one end close to the off-axis, and corresponds to the case that the absolute value of r1/r2 is greater than 1; the rotating block 15N rotates around the vertical rotating pin 101 fixed in the second combined groove space 172N of the pluggable module 1NA, and the rotating block 15N is provided with a rotating shaft hole 153 for connecting with the rotating pin 101. Further, the back surface of the turning piece 15N is a turning piece spring acting surface and can be constituted by a simple planar structure.

Fig. 10 shows a state where the rotary block 15N is mounted in the rotary block mounting groove 1721N of the module case via connection with the rotary pin 101.

In the above-described structure of the rotating block 15N shown in fig. 9, the latching protrusion 151 is configured to interact with the rectangular latching hole 1214N at the control end of the unlocking piece 12N (see fig. 4), and the reset protrusion 152N is configured to interact with the reset edge 112 of the push-pull handle 11A (see fig. 3). The rectangular positioning hole 1214N and the positioning protrusion 151 specifically interact with each other to form a corresponding hole structure edge in the rectangular positioning hole 1214N, which is called a positioning edge. The rectangular reset yielding hole 1213 (see fig. 4) at the control end of the unlocking piece 12N allows the reset protrusion 152N of the rotation block 15N to act on the reset edge 112 of the push-pull handle 11A after yielding, and yields the reset protrusion 152N in the whole process of the unlocking and resetting operations of the pluggable module 1NA, so as to eliminate the contact pushing-down of the unlocking piece 12N itself to the reset protrusion 152N in the moving process, and bring about the additional pushing-down rotation of the rotation block 15N. The specific modes of action referred to above are as follows:

Fig. 11 shows the mutual position relationship between the rotating block 15N, the push-pull handle 11A, and the unlocking piece 12N in the present embodiment at the module unlocking position after the assembly of the pluggable module 1 NA. The rotation block 15N has a rotation block working spring 102 disposed on the back thereof, which is disposed under the reset protrusion 152N and is received in a horizontal transverse receiving hole 1724 of the rotation block mounting groove 1721N (see fig. 6). The push-pull handle 11A is connected to the unlocking piece 12N through the unlocking piece rotating shaft connecting hole 1212 by its rotating shaft 111, when it horizontally pushes the unlocking piece 12N to the module unlocking position, that is, when the unlocking front 1211 on the unlocking arm 121N reaches the locking step surfaces 1711 on both sides of the module housing (see fig. 13B), the rectangular locking hole 1214N at the control end of the unlocking arm 121N will reach right above the locking protrusion 151 of the rotating block 15N, the reset edge 112 of the push-pull handle 11A will reach the right position of the action surface of the reset protrusion 152N of the rotating block 15N as shown in the figure, and the reset protrusion 152N is always in the yielding position of the rectangular reset yielding hole 1213 of the unlocking arm 121N in this process. At this time, under the action of the rotating block operating spring 102, the locking protrusion 151 of the rotating block 15N will be sprung upward into the rectangular locking hole 1214N, and the unlocking plate 12N is locked by the rectangular locking hole 1214N (the locking edge thereof), so that the unlocking plate 12N cannot automatically retract under the restoring force of the return spring 103, and the pluggable module 1NA of the present invention is maintained in the unlocked state. The effective action surface of the blocking projection 151 acting on the blocking edge of the rectangular blocking hole 1214N is a vertical surface to implement effective blocking of the unlocking piece 12N. At this time, if the pluggable module 1NA is installed in the device installation cage 2, the push-pull handle 11A is horizontally pulled in the opposite direction in the unlocked state where the installation cage elastic piece 21 is pushed up by the unlocking piece front edge 1211, so that the module 1NA can be pulled out from the installation cage 2. It can be seen that in this operation of module unlocking and unplugging, the cable to which the pluggable module 1NA is connected does not need to be removed.

After the pluggable module 1NA is pulled out of the installation cage 2, the module needs to be reset next, i.e., the unlocking piece 12N returns to the original position, so that the unlocking front edge 1211 is away from the locking step surface 1711 of the module housing, and the module is locked when being inserted into the installation cage of the device next time. At this time, the push-pull handle 11A can be rotated and lifted upwards, the reset edge 112 of the push-pull handle 11A will act with the reset protrusion 152N of the rotating block 15N at this time, and as the handle rotates, the reset edge 112 will gradually press down the reset protrusion 152N, wherein the surface of the reset protrusion 152N which acts with the reset edge 112 of the handle is a set slope surface (see fig. 9). At the same time, the blocking protrusion 151 connected in series with the reset protrusion 152N and rotating integrally therewith will also move downward until the blocking protrusion is separated from the rectangular blocking hole 1214N of the unlocking sheet. At this point, the locking action of the rotating block 15N on the unlocking piece 12N is released, the unlocking piece 12N will automatically return to the initial position under the restoring force of the return spring 103, and the resetting operation of the module is completed. It can be seen that in the reset operation of the pluggable module 1NA of the present invention, the cable connected to the module 1NA does not need to be removed.

Furthermore, it can be seen that the reset operation can also be performed in a state where the pluggable module 1NA is not unplugged from the installation cage 2, and the reset operation is completely the same, only when there is a vertically close proximity port on the device panel, as shown in fig. 12, it is necessary to ensure the reset operation rotation angle of the push-pull handle 11A, so that the handle will not touch the relevant portion of the upper-end neighboring module or the cable 3 connected thereto, or the in-place reset operation cannot be performed due to the above-mentioned factors. For this purpose, the push-pull handle 11A can be reset at a desired limited rotation angle by setting relevant configuration parameters including the distance r1 between the locking surface of the locking protrusion 151 of the rotary block 15N and the axis of the rotary pin 101, the distance r2 between the resetting surface of the resetting protrusion 152N and the axis of the rotary pin 101, the slope of the resetting surface of the resetting protrusion 152N, and the like. In the case of the embodiment of the present invention directed to a standard stacking cage port of the industry shown in fig. 12, for the illustrated case where the push-pull handle 11A is designed to be about 6 cm in length, the rotation angle required for the repositioning in position is set at 5.75 °, the maximum rotation angle that can be implemented is limited to 7.25 °, above which the rotation would not be possible (see fig. 13C), and the above-described requirements are met. When the length of the handle 11A is reduced, the design values of the rotational angles of the reset operation can be increased accordingly.

According to the unlocking and resetting operation by using the push-pull handle 11A, compared with the operation of the existing straight pull type pull ring mode, the handle moving direction of the module unlocking operation is opposite to the handle moving direction of the outward pulling module and is pushed inwards, so that compared with the operation that the pull ring is pulled outwards by the straight pull type unlocking and pulling module, the situation that the signal is interrupted accidentally due to accidental pulling in the use process of the pluggable module 1NA can not occur, and the pluggable module 1NA can not be unlocked and can not be pulled out due to the operation of directly pulling the handle of the pluggable module 1NA outwards. Meanwhile, the module cannot be unlocked when the handle is rotated and lifted by touching the handle upwards. In addition, even if the handle is touched by mistake and pushed inwards until the handle is unlocked, or the module is unlocked by mistake in the in-place use of the module, namely the module with the wrong line is unlocked, the module can be corrected immediately as long as the module is not operated to be pulled out, the module can be reset in place, the locking state of the module can be recovered, and line signals are not influenced in the process. These advantages are not possessed by the straight pull ring system and the rotary pull ring system. For the rotary pull ring method, since the cable needs to be removed in advance regardless of unlocking or resetting, the signal interruption is inevitable in any situation, including normal unlocking and misoperation.

In summary, the unlocking structure and the operation method of the pluggable module of the present invention provide a complete operation mechanism for unlocking and resetting the module, and can avoid the occurrence of misoperation and accident to the maximum extent, and meanwhile, the related operations are simple and easy to implement.

The arrangement of the handle stopper 1722 of the pluggable module 1NA according to the present invention will be described based on the unlocking and resetting operations of the push/pull handle 11A. As shown in fig. 6 and 7, the grip stopper groove 1722 is formed by two stopper boundary surfaces, i.e., an upper stopper boundary surface and a lower stopper boundary surface, and is configured to perform a stopper function on the stopper post 113 of the push-pull grip 11A. The lower boundary surface of the handle limiting groove 1722 is a horizontal straight surface, which enables the push-pull handle 11A to push the unlocking sheet 12N to move towards the tail end of the module, when unlocking is performed, the handle limiting column 113 can selectively abut against the horizontal straight surface, and simultaneously, under the common constraint of the upper boundary surface of the groove part, the handle 11A is basically controlled to move horizontally until the unlocking position is reached. Fig. 13A shows the position of the stopper post 113 in the handle stopper groove 1722 in the initial horizontal state of the push-pull handle 11A. Here, the position-limiting column 113 abuts against the aforementioned second position-limiting protrusion 1725 disposed on the upper boundary surface of the handle position-limiting groove 1722, and the handle 11A does not rotate or jump upwards without any special external force. The upper boundary surface of the handle limiting groove 1722 is a combined surface combining a curved surface and a horizontal straight surface, the area near the inner section is concave upwards, the outermost side, namely the side near the module port, is a circular arc abdicating curved surface, and the other areas which do not need the handle 11A to rotate and keep the horizontal state are horizontal straight surfaces. The outermost arc-shaped abdicating curved surface on the upper edge interface of the handle limiting groove 1722 allows the push-pull handle 11A to rotate upwards from the horizontal initial position through the limiting column 113. The semi-closed rotary abdicating hole 1215 in the control end of the unlocking piece 12N always abdicating the push-pull handle 11A by upward rotation of the limiting post 113 relative to the unlocking piece 12N, and the basic abdicating is the same in each case.

Figure 13B shows the position of the retention post 113 in the handle retention slot 1722 when the push-pull handle 11A is pushed horizontally inward, i.e., toward the rear of the module, to the unlocked position of the module. In this position, the unlocking piece 12N is caught by the catching projection 151 of the rotating piece 15N through the rectangular catching hole 1214N in the unlocking arm 121N, and the module 1NA is held in the unlocked state. In this state, the upper boundary surface of the handle restraint slot 1722 will allow upward rotation of the restraint post 113 therefrom.

fig. 13C shows the position of the stopper post 113 in the handle stopper groove 1722 when the push-pull handle 11A is rotated upward from the unlock position to perform the module reset operation and the rectangular stopper hole 1214N of the unlock piece is released from the stopper of the stopper protrusion 151 of the rotation block 15N. It can be seen that, for the set maximum allowable reset operation rotation angle of the push-pull handle 11A, the upper boundary surface of the handle stopper groove 1722 is set here as: when the position-limiting column 113 rotates to the angle, the rotation is terminated by the upper limit, and the position-limiting column 113 is driven to be kept below the maximum rotation angle in the following returning process of the unlocking sheet 12N.

At the maximum rotation angle of the reset operation shown in fig. 13C, the unlocking piece 12N has been disengaged from the position of the position-locking protrusion 151 of the rotation block 15N, and at this time, under the action of the unlocking piece return spring 103, the unlocking piece 12N will start to return to its own position, and at the same time, the upper boundary surface of the handle-limiting groove 1722 will drive the handle 11A to return to the horizontal initial state shown in fig. 13A or 13D by restraining the handle-limiting post 113. Meanwhile, the bent structure 1217 on the unlocking arm 121N will reach the aforementioned positioning surface 1717 in the first combined groove space 171 on both sides of the module housing, which represents that the unlocking piece is completely returned, and at this time, the position-limiting column 113 will return to the position of the second position-limiting protrusion 1725 in the handle position-limiting groove 1722.

In addition, fig. 13E shows a state where the handle is stopped after passing over the first stopper protrusion 1216 after the handle stopper post 113 sequentially overcomes and passes over the second stopper protrusion 1725 and the first stopper protrusion 1216 by rotating the handle upward from the horizontal initial position of the push-pull handle 11A. The state is set to: in the initial state of the pluggable module 1NA of the present invention, the push-pull handle 11A can be rotated upward to be lifted up, so that it can be automatically maintained at an angle just after the first limiting protrusion 1216, thereby facilitating operations such as plugging cables into and out of the module when necessary. The handle 11A is returned to the horizontal position by releasing the rotation and lifting state, and the handle is pressed downward to make the limit post 113 sequentially return to overcome the two limit protrusions. Furthermore, according to the structure of this embodiment, the push-pull handle 11A can continue to rotate upward after passing over the first position-limiting protrusion 1216 until it is completely turned up toward the rear end of the module, until the relevant portion of the handle touches the corresponding portion of the module housing. While this handle may be fully flipped back, and not for the purposes of the present invention, and not as a standard matter of operation in the operation and use of the pluggable module 1NA of the present invention, its use may provide certain operational convenience for certain special situations, such as the inspection of certain surface conditions of ports of optoelectronic modules under a microscope, and for the assembly process of the pluggable module 1NA, the latter description of which is provided below with respect to the module assembly process. Meanwhile, in order to prevent such an unrestricted, especially inadvertent, occurrence of the push-pull grip 11A after having passed over the first stopper protrusion 1216 from being abruptly turned back due to the posture of the module, causing possible damage to the corresponding portions of the grip and the module case, the grip portion 116 of the push-pull grip 11A in the embodiment described, which comes into contact with the module case when it is turned back, as shown in fig. 3, may be subjected to a preventive surface rounding treatment.

Referring to the drawings, the pluggable module 1NA of the present invention has the following assembling process and assembling condition of each component:

Step 1: the push-pull handle 11A is connected to the rotating shaft connecting hole 1212 of the unlocking piece 12N through the rotating shaft 111 thereof, completing the assembly between the push-pull handle 11A and the unlocking piece 12N. After the assembly, the limit post 113 of the push-pull handle 11A falls into the semi-closed rotation abdicating hole 1215 of the unlocking piece 12N.

Step 2: the turning block 15N is placed in the turning block mounting groove 1721N in the second combined groove space 172N on the side of the housing base 13N, the rotation shaft hole 153 of the turning block 15N is aligned with the turning pin mounting shaft hole 1723 in the turning block mounting groove 1721N, and at this time, the turning pin 101 is inserted into the turning pin mounting shaft hole 1723 on the base 13N from the side where the housing base 13N and the housing cover plate 14 are connected, so as to pass through the turning block rotation shaft hole 153 and enter the other end of the turning pin mounting shaft hole 1723 until the end where the turning pin 101 and the housing cover plate 14 are connected is completely submerged into the housing base 13N. The rotation pin 101 and the rotation pin mounting hole 1723 are tightly fitted, the rotation pin 101 is retained in the rotation pin mounting hole 1723 after installation, and at this time, the initial installation of the rotation block 15N on the housing base 13N is completed. The mounted rotary piece 15N is reciprocally rotatable about the rotary pin 101.

And 3, step 3: the turning blocks 15N primarily installed at both sides are respectively rotated up to a certain angle, the turning block working springs 102 are respectively inserted into the horizontal transverse receiving holes 1724 of the turning block mounting grooves 1721N respectively located under the turning blocks 15N, and then the turning blocks 15N at both sides are simultaneously pressed down by fingers or a simple tool to press the turning block working springs 102. Then, the bending structures 1217 on both sides of the unlocking piece 12N are disposed in the vertical mounting groove 1715 from top to bottom through the vertical mounting groove 1715 in the first combined groove space 171 on the side surface of the housing base 13N, and the unlocking piece 12N is sleeved on the housing base 13N to be completely installed. In particular, in this process, the push-pull handle 11A assembled with the unlocking piece 12N may be completely lifted toward the tail end of the unlocking piece 12N in advance, so as to temporarily omit the positioning and installation of the handle stopper post 113 in the handle stopper groove 1722 at the front end of the housing base 13N. Then, the unlocking piece 12N is continuously installed downwards, when the unlocking arm 121N starts to touch the finger or tool pressing the rotation block 15N, the finger or tool is gradually released, so that the unlocking arm gradually replaces the finger or tool and keeps continuously pressing the rotation block 15N in the downward moving process until the unlocking arm 121N completely falls into the first combined groove space 171 on the two sides of the housing base 13N, and thus, the installation of the unlocking piece 12N on the housing base 13N is completed. After the unlocking piece 12N is installed in place, the bending structure 1217 of the unlocking piece 12N is located in the horizontal longitudinal accommodating groove 1716 in the first combined groove space 171 on the two sides of the housing base, at this time, the unlocking piece 12N can be slid to the foremost position in the direction of the front end of the module, then the push-pull handle 11A which is turned up backwards is turned back and pressed down to the horizontal position, at this time, the handle limiting column 113 enters the handle limiting groove 1722 at the front end of the module housing, and the push-pull handle 11A can drive the unlocking piece 12N to slide back and forth in the horizontal direction at this time.

And 4, step 4: the unlocking piece return spring 103 is plugged into the horizontal longitudinal accommodating groove 1716 on both sides of the housing base 13N through the return spring mounting square hole 1218 on the unlocking arm 121N, one end of the spring abuts against the unlocking piece bending structure 1217, and the other end abuts against the inner wall of the horizontal longitudinal accommodating groove 1716 on the side close to the module tail end. At this time, the unlocking piece 12N receives the urging force of the return spring 103, and automatically slides until the bent structure 1217 thereof abuts against the inner wall of the housing horizontal longitudinal direction accommodating groove 1716 on the module front end side, that is, the aforementioned positioning surface 1717. To this end, the major components of the housing of the pluggable module 1NA are completely assembled on the housing base 13N.

And 5, step 5: the mounting of the respective components including the module circuit board 104 inside the housing base 13N is completed.

And 6, step 6: finally, the housing cover 14 is connected to the housing base 13N and fixed by the fastening screws 105, and the pluggable module 1NA is assembled.

According to the assembly process and the content, the pluggable module using the unlocking structure has the advantages of simple and quick assembly process, firm and stable assembly, no hidden danger, no need of special or special tools and good operability and practicability.

In other embodiments of the present invention, the basic shape of the handle body of the push-pull handle 11A may also be in the form of push-pull rings 11A +, 11B, 11C of pluggable modules 1NA +, 1NB, 1NC as shown in fig. 14A-C, respectively, according to the arrangement of the panel ports of the applied device, including the arrangement direction thereof, and the consideration or requirement of the connected cables in terms of wiring in the use environment, wherein the module 1NA + is still a relatively long handle case, and the modules 1NB, 1NC are designed as short handles. In the three embodiments, the length of the bent portion of the hand-touching end 114L, which is bent at 45 ° specially at the end of the handle body of the push-pull handle 11A in the previous embodiment, is reduced to form the push-pull ring end 114S suitable for pushing purpose, and at the same time, a hollow ring-shaped structure 117 is added at the end of the handle body, or a "U" -shaped hollow ring-shaped structure 118 at the connecting end of the handle body and the unlocking piece is directly used as an auxiliary for pulling the push-pull ring under a certain shortest handle body design as shown in fig. 14C. In the case of the short shaft design shown in fig. 14B and 14C, the rotation angle of the reset operation can be increased to some extent compared to the previous long shaft design, and therefore the relevant structural parameters of the rotating block 15N can be adjusted according to the above-mentioned information. This adjustment is not illustrated in fig. 14B and 14C.

Based on the fact that the operations such as unlocking and the like of the pluggable module are in a push-pull mode, the push-pull handle or the push-pull ring of the pluggable module is integrally made of metal materials such as light aluminum alloy materials.

In addition to the structure of the rotating block 15N in the above embodiment, the coaxial serial conjoined rotating structure 15' in the present invention can also adopt the rotating block 15F shown in fig. 15, in which the reset protrusion 152F is located at the end far from the rotating shaft 101 relative to the same side position-locking protrusion 151, and the determination of the relevant structural parameters is still based on the same setting of the rotating angle of the handle reset operation as the previous embodiment, corresponding to the case that the absolute value of r1/r2 is less than 1. Fig. 16 shows the rotation block 15F being mounted in the rotation block mounting groove 1721F of the corresponding pluggable module 1FA housing.

Fig. 17 shows an exploded view of the rotating block 15F, and the push-pull handle 16A, the unlocking piece 12F, and the rotating block 15F of the corresponding pluggable module 1FA that are engaged with the rotating block 15F. Compared with the push-pull handle 11A in the previous embodiment (see fig. 3), in this embodiment, the outline of the outer edges of the two side surfaces of the handle connecting end of the handle 16A is adjusted as shown in the figure, so as to provide a handle reset edge 162 corresponding to the rotating block 15F and a special relief gap 169 of each acting protrusion of the rotating block 15F; in contrast to the unlocking tab 12N of the previous embodiment (see fig. 4), the original rectangular detent hole 1214N becomes semi-enclosed in this embodiment, and the rectangular detent opening 1214F, which serves both the abdicating and detent functions, transitions the original rectangular reset abdicating hole 1213 to another special initial abdicating hole 1219.

Fig. 18A shows a schematic side view of the pivot block 15F and the unlocking piece 12F in their initial positions mounted on their respective module housings, and fig. 18B shows the same after the handle 16A has been added. Fig. 19A and 19B show the two schematic diagrams in the unlocked position, respectively. Therefore, the rectangular blocking opening 1214F of the unlocking piece 12F with the functions of abdicating and blocking is still abdicating the reset protrusion 152F of the rotating block 15F in all states and operation processes of the module, so as to eliminate the additional downward pressing of the rotating block 15F caused by the self piece body of the unlocking piece 12F in the moving process, so that the transverse accommodating space of the module shell to the rotating block 15F is insufficient; the initial yielding hole 1219 is a special yielding for the locking protrusion 151 of the rotating block 15F only in the initial state, so as to eliminate the performance degradation and failure of the rotating block working spring 102 caused by the long-term pressing state of the unlocking sheet body on the locking protrusion 151 of the rotating block 15F in the normal state of the module in the specific structure of this embodiment.

Fig. 20 shows the mutual position relationship between the rotating block 15F, the push-pull handle 16A and the unlocking piece 12F when the pluggable module 1FA is in the module unlocking position according to this embodiment. Fig. 21A and 21B are schematic overall external views of the pluggable module 1FA in the initial and unlocked positions according to this embodiment. In addition, the module can also be used with the various push-pull ring handle configurations shown in FIGS. 14A-C.

As can be seen from the schematic drawings of the above two embodiments of the rotating block structure, the difference between the two embodiments in use is: aiming at the same design of the handle reset operation rotation angle, the reset protrusion 152N is located on the rotating block 15N close to the rotating shaft 101 relative to the clamping protrusion 151 on the same side, the structure is compact, but the acting force borne by the reset protrusion 152N is relatively large and is corresponding to a labor-saving lever model, the reset protrusion 152F is located on the rotating block 15F far from the rotating shaft 101 relative to the clamping protrusion 151 on the same side, the size is large, but the acting force borne by the reset protrusion 152F is relatively small and is corresponding to a labor-saving lever model.
