Description

  The present invention relates to a pluggable optical transceiver module that can be inserted into and removed from a cage of a host device.

  The pluggable optical transceiver module must have an insertion / extraction structure that allows insertion / extraction from / to the cage of the host device. In particular, when the end of the optical transmission cable (optical connector) is inserted into the optical receptacle of the pluggable optical transceiver module, removal from the cage is prohibited, and only when the end of the optical transmission cable is not inserted There is a need for an insertion / extraction structure that allows for removal from the cage. It is well known to use a bar structure for this insertion / extraction structure, and various proposals have been made for this bar structure.

For example, a rotatable tension rod (extraction bar), a cross bar that converts the pivoting motion of the tension rod into a sliding motion, a slide bar that slides on the latch base, and the relationship between the optical transceiver module and the communication device. There has been known one provided with a movable latch for releasing the engagement (see, for example, Patent Document 1).
In addition, in order to firmly fix the lever (extraction bar) and the shaft that converts the pivoting motion of the lever into a sliding motion, a retaining ring is used, or both ends of the shaft are riveted or welded. (For example, refer to Patent Document 2).
In addition, there is also known one in which a contact portion that converts a rotation operation of a bale (extraction bar) into a linear operation is formed integrally with an actuator (for example, see Patent Document 3).

However, in the conventional configuration disclosed in Patent Document 1, there is a problem that the fitting amount between the tension rod and the crossbar is small, and if the force is applied to the tension rod from the side, the tension rod may easily come off. is there. In this case, the pluggable optical transceiver module cannot be removed from the cage. Similarly, the conventional configuration disclosed in Patent Document 3 has a problem that the veil is easily removed.
On the other hand, the conventional configuration disclosed in Patent Document 2 can solve the above problems. However, in this conventional configuration, in order to firmly fix the lever and the shaft, it is necessary to add a part, a secondary process such as a rivet process or a welding process. Therefore, there is a problem that the cost increases due to an increase in the number of parts, an increase in labor for secondary processing, a deterioration in assemblability, and the like.

  The present invention has been made to solve the above-described problems, and is a pluggable optical transceiver module capable of avoiding the removal bar from being detached from the pluggable optical transceiver module with an inexpensive configuration compared to the conventional configuration. It is intended to provide.

A pluggable optical transceiver module according to the present invention is inserted in a cage of a host device and is coupled to the cage by a coupling mechanism, a base assembled to the body, and a pivotable assembly to the base The removal bar, the slider that slides on the base and contacts the coupling mechanism to release the coupling between the main body and the cage, and the conversion that converts the rotation of the removal bar into the sliding movement of the slider The removal bar is assembled to the base at an angle outside the range with respect to the range in which the removal bar can rotate with the mechanism and the base with the removal bar assembled to the main body. is obtained by a assembly mechanism allows attached.

Embodiment 1 FIG.
1 is an exploded perspective view showing a configuration example of a pluggable optical transceiver module 1 according to Embodiment 1 of the present invention, and FIG. 2 is a perspective view showing a configuration example after assembly.
The pluggable optical transceiver module 1 is a module that can be inserted into and removed from the cage 2 of the host device (see FIGS. 13 and 14). 13 and 14, the cage 2 is provided with a tongue piece 21 having a coupling hole 211 at the open end. Further, the tongue piece 21 has a bent portion 212 that is bent outward at the tip.
As shown in FIGS. 1 and 2, the pluggable optical transceiver module 1 includes a main body 11, a front base (base) 12, a removal bar 13 and a slider 14.

First, the configuration of the main body 11 will be described.
The main body 11 is inserted into and coupled to the cage 2 of the host device. As shown in FIG. 3, the main body 11 is provided with a coupling protrusion 111 on one side surface (bottom surface). When the main body 11 is inserted into the cage 2, the coupling protrusion 111 is fitted into the coupling hole 211 of the tongue piece 21 provided in the cage 2 to couple the main body 11 and the cage 2. . Here, the tongue piece 21 having the coupling hole 211 and the coupling protrusion 111 constitute a coupling mechanism that couples the main body portion 11 and the cage 2 when the main body portion 11 is inserted into the cage 2. The coupling mechanism is not limited to the configuration shown in the drawing, and the main body 11 and the cage 2 can be coupled by inserting the main body 11 into the cage 2, and the slider 14 is slid to come into contact. Any configuration that can release the coupling between the main body portion 11 and the cage 2 can be used.

  The main body 11 is provided with a slider restricting protrusion 112 on the one side surface. The slider restricting protrusion 112 restricts sliding of the slider 14 toward the cage 2 by contacting a slider restricting notch 147 (to be described later) of the slider 14.

  As shown in FIGS. 1 and 3, the main body 11 is provided with a fixing groove 113. Here, the case where the fixing grooves 113 are provided on the upper surface and both side surfaces of the main body 11 is shown. The fixing groove 113 firmly fixes the front base 12 to the main body 11 by fitting a fixing claw 125 (to be described later) of the front base 12.

Next, the configuration of the front base 12 will be described.
The front base 12 is assembled to the front surface of the main body 11 (the side opposite to the insertion side into the cage 2). The front base 12 has a housing structure having an opening in the axial direction of the main body 11. As shown in FIG. 4, the front base 12 is provided with a keyway hole (a retaining hole) 121 on the tip side of both side surfaces (left and right side surfaces). This key groove hole 121 allows a key protrusion 1332 of a rotary shaft 133 with a key protrusion, which will be described later, of the extraction bar 13 to be inserted, and rotatably holds the rotary shaft 1331 of the rotary shaft 133 with a key protrusion. The key groove hole 121 has a key projection 1332 of the rotary shaft 133 with a key projection only at an angle outside the range in which the extraction bar 13 can be rotated when the coupling between the main body 11 and the cage 2 is released. Is configured to be insertable.

  Further, as shown in FIG. 8, the front base 12 is provided with a protrusion 122 at the rear end of one side surface (bottom surface). The protrusion 122 is formed in an inverted L shape and is slidably held by a slider restriction hole 141 described later of the slider 14. Further, the front base 12 is provided with a protrusion 123 at the tip of the one side surface. The protrusion 123 is formed in an inverted L shape and is slidably held by a slider restricting hole 142 described later of the slider 14.

  As shown in FIG. 4, the front base 12 is provided with a slider regulating wall 124 on one side surface (left side surface). The slider regulating wall 124 regulates the sliding of the slider 14 toward the cage 2 when a later-described cam projection 143 of the slider 14 comes into contact.

  As shown in FIG. 1, the front base 12 is provided with a fixing claw 125 inside the housing. Here, a case where the fixing claws 125 are provided on the upper surface and both side surfaces of the front base 12 is shown. In FIG. 1, the illustration of the fixing claw 125 on the right side surface is omitted to make the drawing easier to see. The fixing claw 125 fits in the fixing groove 113 of the main body 11 to firmly fix the front base 12 to the main body 11. The fixing groove 113 and the fixing claw 125 constitute a fixing mechanism that firmly fixes the front base 12 to the main body 11. The fixing mechanism is not limited to the fixing groove 113 and the fixing claw 125, and may be any configuration that can firmly fix the front base 12 to the main body 11.

Next, the configuration of the removal bar 13 will be described.
The extraction bar 13 is rotatably assembled to the front base 12. As shown in FIG. 4, the extraction bar 13 includes a grip portion 131 that is gripped by the user when the pluggable optical transceiver module 1 is pulled out of the cage 2, and is perpendicular to both ends of the grip portion 131 (meaning a substantially vertical meaning). And a rotation portion 132 whose end is a rotation axis.

  The extraction bar 13 is provided with a rotation shaft 133 with a key protrusion on the inner side of the end portions of the both rotation portions 132. The rotation shaft 133 with a key protrusion includes a rotation shaft 1331 and a key protrusion (a retaining protrusion) 1332 provided at the tip of the rotation shaft 1331 and wider than the rotation shaft 1331. The key protrusion 1332 can be inserted into the key groove hole 121 of the front base 12 only at an angle outside the rotation range of the removal bar 13 when the coupling between the main body 11 and the cage 2 is released. It is configured in a simple shape. Here, the key groove hole 121 and the rotary shaft 133 with the key protrusion are at an angle outside the range with respect to the range in which the extraction bar 13 can be rotated when the coupling between the main body 11 and the cage 2 is released. An assembly mechanism is provided that enables the removal bar 13 to be assembled to the front base 12.

  In addition, the removal bar 13 is provided with a cam plate 134 at the end of one rotating portion 132. The cam plate 134 comes into contact with a cam projection 143 or a cam projection 144 (to be described later) of the slider 14 when the removal bar 13 is rotated about the rotary shaft 133 with a key projection as an axis. The rotating operation is converted into a sliding operation of the slider 14.

Next, the configuration of the slider 14 will be described.
The slider 14 releases the coupling between the main body 11 and the cage 2 by sliding on one side surface (bottom surface) of the front base 12 and contacting the coupling mechanism. As shown in FIG. 5, the slider 14 is provided with a slider restricting hole 141 at the center. The slider restricting hole 141 includes an insertion hole 1411 provided at the tip and a slide groove 1412 provided on the rear side. The insertion hole 1411 allows the protrusion 122 of the front base 12 to be inserted. The slide groove 1412 holds the protrusion 122 inserted from the insertion hole 1411 so as to be slidable. Further, the slider 14 is provided with a slider restriction hole 142 at the tip. The slider restricting hole 142 includes a slide groove 1421 that slidably holds the protrusion 123 of the front base 12.

  Further, as shown in FIG. 1, the slider 14 is provided with cam protrusions 143 and 144. The cam protrusions 143 and 144 come into contact with the cam plate 134 when the extraction bar 13 is rotated, and convert the rotation operation of the extraction bar 13 into a slide operation of the slider 14. Here, the cam plate 134 and the cam protrusions 143 and 144 constitute a conversion mechanism that converts the rotation operation of the removal bar 13 into the slide operation of the slider 14. Note that the conversion mechanism is not limited to the configuration shown in the figure, and may be any configuration that can convert the rotation operation of the extraction bar 13 into the slide operation of the slider 14.

  Further, the bar 14 is provided with a removal bar restricting projection 145. The removal bar restricting protrusion 145 restricts the rotation of the removal bar 13 by contacting the cam plate 134 of the removal bar 13.

Further, as shown in FIG. 5, the slider 14 is provided with a release protrusion 146 at the rear end. The release protrusion 146 contacts the bent portion 212 of the tongue piece 21 of the cage 2 as the slider 14 is slid to the cage 2 side, and pushes the tongue piece 21 outward.
The slider 14 is provided with a slider regulation notch 147 at the rear end. The slider regulation notch 147 regulates sliding of the slider 14 toward the cage 2 by contacting the slider regulation projection 112 of the main body 11.

Next, an assembly example of the pluggable optical transceiver module 1 will be described. First, an example of assembling the extraction bar 13 to the front base 12 will be described.
In the example of assembling the extraction bar 13 to the front base 12, as shown in FIG. 4, first, the direction of the key protrusion 1332 of the rotary shaft 133 with the key protrusion of the extraction bar 13 is changed to the key groove hole of the front base 12. The angle of the extraction bar 13 is adjusted to match the direction of 121. At this time, the angle of the extraction bar 13 is an angle out of the range relative to the rotatable range of the extraction bar 13 when the pluggable optical transceiver module 1 is extracted from the cage 2. Then, as shown in FIGS. 6 and 7, the key protrusion 1332 of the rotating shaft 133 with the key protrusion of the removal bar 13 is inserted into the key groove hole 121 of the front base 12. Thereby, the rotating shaft 1331 of the rotating shaft 133 with a key protrusion of the extraction bar 13 is rotatably held in the key groove hole 121 of the front base 12.

Next, an example of assembling the slider 14 to the front base 12 will be described.
In the example of assembling the slider 14 to the front base 12, as shown in FIGS. 8 and 9, the slider 14 is inserted so that the protrusion 122 of the front base 12 is inserted into the insertion hole 1411 of the slider restricting hole 141 of the slider 14. Place on one side (bottom surface) of the front base 12. In this state, the removal bar 13 is rotated in the direction of the arrow 1001 as shown in FIG. As a result, the cam plate 134 and the cam projection 144 come into contact with each other, the slider 14 slides in the direction of the arrow 1002, and the projection 122 and the projection 123 are held in the slide groove 1412 and the slider regulation hole 142 of the slider regulation hole 141, respectively. .

Next, an example of assembling the front base 12 to the main body 11 will be described.
In the example of assembling the front base 12 to the main body 11, as shown in FIG. 11, the slider restriction notch 147 of the slider 14 is aligned with the slider restriction projection 112 of the main body 11, and the front base 12 is attached to the main body 11. insert. At this time, the fixing claws 125 of the front base 12 are fitted into the fixing grooves 113 of the main body 11, and the front base 12 is firmly fixed so as not to be easily detached from the main body 11.

  Then, after the assembly of the pluggable optical transceiver module 1 is completed, as shown in FIG. 12, the slider regulation notch 147 contacts the slider regulation projection 112 and the cam plate 134 contacts the removal bar regulation projection 145. Thus, the movable range of the slider 14 and the extraction bar 13 is limited. At this time, the pivotable range of the removal bar 13 is the angle of the removal bar 13 when the rotary shaft 133 with the key protrusion is inserted into the key groove hole 121 when the removal bar 13 is assembled to the front base 12. The range is not included. Therefore, the removal bar 13 does not come off the front base 12 after the assembly of the pluggable optical transceiver module 1 is completed.

Next, an example of insertion / extraction between the pluggable optical transceiver module 1 configured as described above and the cage 2 will be described.
When the pluggable optical transceiver module 1 is inserted into the cage 2, the main body 11 of the pluggable optical transceiver module 1 is inserted into the cage 2 as shown in FIG. 13. Thereby, the coupling protrusion 111 of the main body 11 fits into the coupling hole 211 of the cage 2, and the pluggable optical transceiver module 1 and the cage 2 can be coupled.

  On the other hand, when the pluggable optical transceiver module 1 is removed from the cage 2, the removal bar 13 is rotated in the direction of the arrow 1401, as shown in FIG. As a result, the cam plate 134 of the removal bar 13 and the cam protrusion 143 of the slider 14 come into contact with each other, and the slider 14 slides in the direction of the arrow 1402. Then, the release protrusion 146 of the slider 14 comes into contact with the bent portion 212 of the tongue piece 21 of the cage 2 and pushes the tongue piece 21 outward. Thereby, the coupling protrusion 111 is detached from the coupling hole 211 of the tongue piece 21. In this state, the extraction operation from the cage 2 is completed by grasping the extraction bar 13 and extracting the pluggable optical transceiver module 1 from the cage 2 in the direction of the arrow 1403.

  In addition, in the above, although the material of the front base 12 and the extraction bar 13 is not mentioned, it can be a resin molded product, for example. In this case, compared to the case of using a metal, the material cost is low, and the manufacturing cost is low because the manufacturability is good. Further, the heat generated by the pluggable optical transceiver module 1 is not easily transmitted.

  As described above, according to the first embodiment, when the coupling between the main body 11 and the cage 2 is released from the front base 12 and the removal bar 13, the removal bar 13 can be rotated. Since the assembling mechanism (the key groove hole 121 and the rotating shaft 133 with the key protrusion) that allows the removing bar 13 to be assembled to the front base 12 at an angle outside the above range is provided, the removing bar 13 transmits and receives pluggable light. It is possible to avoid detachment from the module 1. Further, by using the above assembly mechanism, it is not necessary to add a part such as a retaining ring having a conventional configuration, secondary processing such as rivet processing or welding processing is unnecessary, and assembly is also good. The conventional configuration as in Patent Document 2 can be configured at a low cost.

  In the above description, the case where the key groove hole 121 and the key protrusion 1332 having the shapes as shown in FIG. 4 are provided is shown, but the present invention is not limited to this, and the shapes of the retaining holes and retaining protrusions may be appropriately set. It can be changed.

Embodiment 2. FIG.
FIG. 15 is a perspective view showing a configuration example of the front base 12 and the extraction bar 13 in Embodiment 2 of the present invention. The front base 12 and the extraction bar 13 in the second embodiment shown in FIG. 15 are obtained by adding a holding groove 126 to the front base 12 in the first embodiment and adding a holding projection 135 to the extraction bar 13. . Other configurations are the same, and the same reference numerals are given and description thereof is omitted.

  The holding groove 126 is a groove provided at the tip of both side surfaces (left and right side surfaces) of the front base 12. The holding projection 135 is provided on the inner side of the rotary shaft 1331 of the extraction bar 13 and fits into the holding groove 126 when the pluggable optical transceiver module 1 is inserted into the cage 2. The holding groove 126 and the holding protrusion 135 constitute a holding mechanism that holds the extraction bar 13 on the front base 12 in a state where the main body 11 and the cage 2 are coupled.

  By providing this holding mechanism, it is possible to prevent the extraction bar 13 from rotating carelessly in a state where the pluggable optical transceiver module 1 is inserted into the cage 2. In addition, since the fitting amount of the holding groove 126 and the holding protrusion 135 in this holding mechanism is small, the user can easily hold the holding bar 131 by holding and rotating the holding portion 131 of the removal bar 13. It can be canceled.

  Further, the holding mechanism is not limited to the configuration shown in the drawing, and may be any configuration that can hold the extraction bar 13 on the front base 12 in a state where the main body 11 and the cage 2 are coupled. For example, as the holding mechanism, a holding protrusion may be provided on the front base 12 and a holding groove in which the holding protrusion is fitted may be provided in the extraction bar 13.

Embodiment 3 FIG.
In the first embodiment, the case where the front base 12 is provided with the key groove hole 121 and the removal bar 13 is provided with the rotary shaft 133 with the key protrusion is shown. However, as shown in FIG. It is also possible to provide the rotary shaft 127 with a key projection in the key bar and to provide the key groove hole 136 in the removal bar 13. The rotation shaft 127 with key protrusion and the key groove hole 136 are configured in the same manner as the rotation shaft 133 with key protrusion and the key groove hole 121 of the first embodiment. Even with the configuration shown in FIG. 16, the same effect as in the first embodiment can be obtained. Further, a fixing mechanism similar to that of the second embodiment may be added to the configuration shown in FIG.

  In the present invention, within the scope of the invention, any combination of the embodiments, or any modification of any component in each embodiment, or omission of any component in each embodiment is possible. .
