Description

Housing structure with latch mechanism and optical fiber transceiver with same

The technical field is as follows: the present invention relates to the field of Fiber optic transceivers (Fiber optic transceivers), and more particularly, to a housing structure with a latch mechanism for use as a device housing of a Fiber optic transceiver.

Background art:

as is known, fiber optic transceivers, also known as optical-to-electrical converters, function to convert optical and electrical signals to and from each other. Generally, the optical fiber transceiver has an electrical connection side for connecting an ethernet connector of a network device (such as POE device or network switching device) and an optical connection side for connecting an optical fiber cable. According to the arrangement, the optical fiber transceiver can convert the electric signal into the optical signal and then transmit the optical signal through the optical fiber cable. Meanwhile, the optical fiber transceiver can also convert the optical signal into an electrical signal and then transmit the electrical signal to the network equipment.

It is necessary for network equipment engineers to know that the maximum transmission distance of a network cable is typically 100 meters, and therefore, when a large network (e.g., a large network monitoring system) is deployed, a plurality of POE devices and optical fiber cables must be used in cooperation. Unlike network cables, the transmission distance of single-mode fibers is over 10 kilometers, while the transmission distance of multimode fibers can reach up to 2 kilometers. When POE devices and optical fibers are used, fiber optic transceivers become an indispensable and important electronic component.

For example, taiwan new patent No. M618563 discloses an optical fiber transceiver. According to the disclosure of taiwan new patent No. M618563, the optical fiber transceiver includes: the electronic component comprises a shell, a circuit board arranged in the shell, an electronic chip and necessary electronic components arranged on the circuit board, an electric connection unit arranged on one side of the circuit board, an optical connection unit arranged on the other side of the circuit board, and a pull handle (pull tab).

Fig. 1 shows a perspective view of a conventional optical fiber transceiver. As shown in fig. 1, a known optical fiber transceiver 1a includes: the portable electronic device comprises a base 11a, a cover 12a and a pull handle unit, wherein the cover 12a is combined with the base 11a to form a shell with a front opening and a rear opening. It should be noted that the pull handle unit includes a connecting member 14a and a pull handle 15a, wherein the connecting member 14a has two first coupling segments (segments) 141a for respectively connecting to the side surfaces of the cover 12a, a second coupling Segment 142a connected to the two first coupling segments 141a, and two third coupling segments 143a connected to the second coupling Segment 142 a. More specifically, the second coupling segment 142a is attached to the upper surface of the cover 12a, and the pull handle 15 has a pull handle tongue 151a and two fourth coupling segments 152a respectively connected to the second third coupling segments 143 a. In addition, a fastening portion 1411a is formed at an end of the first coupling section 141a in the prior art.

Fig. 2 is a perspective view of a conventional PCI-E optical fiber QSFP (quadrature Small Form-factor Pluggable) network card, and fig. 3 is a perspective view of a PCI-E optical fiber QSFP network card connected with an optical fiber transceiver. As shown in fig. 2, the PCI-E optical fiber QSFP network card 2a has two QSFP connectors 21a, and two sides of an outer shell (cage) of each QSFP connector 21a are respectively designed with a butting piece 211 a. Further, as shown in fig. 3, after the optical fiber transceiver 1a is inserted into the QSFP connector 21a, the abutting part 211a of the QSFP connector 21a abuts against the buckling part 1411a of the connecting part 14a, thereby fixing the optical fiber transceiver 1a in the QSFP connector 21 a.

It should be noted that, when the maintenance/replacement of the optical fiber transceiver 1a is performed, the maintenance personnel can pull the pulling handle 15a backward to drive the connecting piece 14a to move backward, so that the buckling portion 1411a is disengaged from the abutting of the abutting piece 211 a. The service person can then continue to pull back the pull handle 15a, or directly hold the entire housing of the fiber optic transceiver 1a and pull it back, thereby removing the fiber optic transceiver 1a from the POE device or network switching device. Unfortunately, practical experience has shown that, because the connector 14a is not provided with a latching mechanism, anyone can remove the fiber optic transceiver 1a from the QSFP connector 21a by pulling back on the pull handle 15a with force. Therefore, the design of the conventional optical fiber transceiver 1a is still not perfect.

As can be seen from the foregoing description, the conventional optical fiber transceiver 1a needs further improvement due to the lack of the locking mechanism. In view of the above, the inventor of the present invention has made an effort to develop and complete a housing structure with a latch mechanism and an optical fiber transceiver having the housing structure according to the present invention.

In particular, the latch unit has a latch member exposed from the accommodating member and the cover body, so as to latch the connecting member of the pull handle unit on the cover body. According to the design of the invention, under the condition that the bolt piece is exposed out of the cover body, the force is applied to the pull handle, so that the connecting piece cannot be pulled to move, and the bolt locking effect of the connecting piece and the pull handle is realized.

Fig. 6 and 7 are first and second exploded perspective views of a housing structure with a latch mechanism according to the present invention. As shown in fig. 4 to 7, the housing structure 1 with latch mechanism of the present invention is applied as a housing device of an optical fiber transceiver, and includes: a base 11, a cover 12, a container 13, a connector 14, a handle 15, and a latch unit 16. In more detail, the cover 12 is combined with the base 11 to form a housing having a front opening and a rear opening, and the cover 12 has a first through hole 121 adjacent to the rear opening.

Fig. 8 is a perspective view of the cover 12, the accommodating member 13, and the latch unit 16 shown in fig. 6. In particular, the present invention provides a receptacle 13 within the housing at the rear opening. As shown in fig. 6 and 8, the accommodating part 13 has an accommodating space 131, an upper opening communicating between the accommodating space 131 and the first through hole 121, and a lower opening communicating with the accommodating space 131. On the other hand, the connecting member 14 has two first coupling segments (segments) 141 for respectively connecting to the side surfaces of the cover 12, a second coupling Segment 142 connected to the two first coupling segments 141, and a third coupling Segment 143 connected to the second coupling Segment 142. The second coupling segment 142 is attached to the upper surface of the cover 12, and has a second through hole 1421 communicating with the first through hole 121.

In more detail, the second coupling section 142 is a pi-shaped belt body including a middle portion, a first side portion and a second side portion, and the second penetration hole 1421 is formed on the middle portion. Moreover, the first coupling section 141 is an elastic arm, and two side surfaces of the cover 12 are respectively provided with a recessed area 122 for accommodating the elastic arm. As shown in fig. 3 and 4, the elastic arm has a fastening portion 1411, and the recessed area 122 has a fastening groove 1221 for the fastening portion to fasten therein. On the other hand, the handle 15 has a handle tongue 151 and two fourth coupling sections 152 respectively connected to the third coupling sections 143. Furthermore, the surface of the pull tab 151 is provided with a slip-resistant structure.

According to the design of the present invention, the latch unit 16 is accommodated in the accommodating space 131, and has a bolt 161, a locking member 162, an elastic member 163, and a pad 164. Wherein the bolt 161 passes through the first through hole 121 and the second through hole 1421 to expose the second coupling section 142. The locking member 162 has a locking portion 1621 and a head portion 1622, wherein the locking portion 1621 is locked into the accommodating space 131 from the lower opening, and the head portion 1622 abuts against the bottom of the accommodating member 13 to cover the lower opening. On the other hand, the elastic element 163 is accommodated in the accommodating space 131 and disposed on the lock-in portion 1611. Furthermore, the pad 164 is accommodated in the accommodating space 131 and located between the bolt 161 and the elastic member 163. Further, the elastic member 163 may be a spring or a leaf spring.

Fig. 9A-9F are illustrations of the application of a fiber optic transceiver having a housing structure with a latch mechanism of the present invention. It is known that the optical fiber transceiver has an electrical connection side for connecting an ethernet connector of a network device (such as POE device or network switching device) and an optical connection side for connecting an optical fiber cable. As shown in fig. 9A and 9B, the optical fiber transceiver having the housing structure 1 with latch mechanism of the present invention is connected to a QSFP network card connector 21 of a PCI-E optical fiber QSFP network card 2 of the network device. As shown in fig. 9B, each of two sides of the outer housing (cage) of the QSFP connector 21 is designed with an abutting piece 211. With this arrangement, after the optical fiber transceiver including the housing structure 1 with the latch mechanism of the present invention is inserted into the QSFP connector 21, the abutting part 211 of the QSFP connector 21 abuts against the buckling part 1411 of the connecting part 14, thereby fixing the optical fiber transceiver in the QSFP connector 21.

It is noted that fig. 9C and 9D show the housing structure 1 with latch mechanism of the present invention in a sectional view. Referring to fig. 9B and 9C, after the optical fiber transceiver including the housing structure 1 with the latch mechanism of the present invention is inserted into the QSFP connector 21, the bolt 161 of the latch unit 16 (see fig. 6) passes through the first through hole 121 (see fig. 6) and the second through hole 1421 (see fig. 6) to expose the second coupling section 142. In this case, the force applied to the pull handle 15 cannot pull the connecting piece 14 to move, so that the locking effect of the connecting piece 14 and the pull handle 15 is realized.

When it is necessary to remove the optical fiber transceiver including the housing structure 1 with the latch mechanism of the present invention, as shown in fig. 9E and 9F, the user can press the latch 161 downward to be submerged into the accommodating space 131 (refer to fig. 8), and then pull the pull-handle tongue 151 (refer to fig. 9B) so that the entire pull handle 15 pulls the connecting member 14 in a direction away from the rear opening of the housing. At this time, the engaging portion 1411 of the connecting member 14 is moved backward to be disengaged from the abutting of the abutting member 211. Next, as shown in fig. 9F, the user can continue to pull back the pull handle 15, or directly hold and pull back the entire housing of the fiber optic transceiver, thereby removing the fiber optic transceiver containing the housing structure with latch mechanism 1 of the present invention from the POE device or the PCI-E fiber QSFP network card 2 of the network switching device.

As can be seen from the action diagrams of fig. 9A to 9F, after the fiber optic transceiver including the housing structure 1 with latch mechanism of the present invention is connected to the QSFP connector 21a of the network device, the connecting member 14 and the pull handle 15 are latched by the latch unit 16. Therefore, without unlocking the latch unit 16, the fiber optic transceiver incorporating the latch-mechanism housing structure 1 of the present invention cannot be removed from the QSFP connector 21 even by pulling back the pull handle 15 with force. Conversely, when the optical fiber transceiver needs to be detached for maintenance, the optical fiber transceiver can be detached from the QSFP connector 21 only by unlocking the latch unit 16 and pulling the pull handle 15 backward with force. It should be noted that the optical fiber transceiver of the present invention is any one selected from the group consisting of QSFP optical fiber transceiver, QSFP + optical fiber transceiver, and QSFP28 optical fiber transceiver, osfp (actual Small Form Factor plug) optical fiber transceiver, and QSFP-DD (quick Small Form Factor plug-Double transition) optical fiber transceiver.

Thus, the housing structure with latch mechanism and the optical fiber transceiver having the housing structure of the present invention have been fully and clearly described above. It should be emphasized, however, that the detailed description above is specific to possible embodiments of the invention, but the embodiments are not intended to limit the scope of the claims, and all equivalent implementations or modifications that do not depart from the technical spirit of the invention are intended to be included within the scope of the claims.
