Description

Optical fiber transmission module

Technical Field

The present invention relates to an optical fiber transmission module, and more particularly, to an optical fiber transmission module for optical fiber transmission or signal transmission.

Background

The rapid growth in demand for network capacity has promoted the development of optical communication technology, which is also widely used, and has higher and higher requirements for communication speed and quality. Since the optical communication industry using optical fiber network transmission has become the center of the communication industry because it can provide fast and large-scale information transmission, and the optical fiber application products related to optical communication are becoming more and more important.

The optoelectronic industry is currently a field of application that combines electronics (electronics) with optics (optics). The key components are optical transceiver modules, which include an optical transmitter (optical-transmitter) and an optical receiver (optical-receiver) or an optical-transceiver module (optical-transceiver) integrating both of them. The function of an optical transmitter is to convert electrical signals into optical signals for transmission, while the main function of an optical receiver is to convert received optical signals into electrical signals.

The optical transceiver module has been developed from an early GBIC (Gigabit Interface Converter) surface to a MINI GBIC (Gigabit Interface Converter) with a smaller size, to an sff (Small Form-Factor) surface and a QSFP +/QSFP DD/OSFP … with hot-swap function developed according to the industry requirement. However, since the size is too small to be easily inserted and removed by a user, the optical transceiver module with the ejector mechanism is derived.

Related art such as US patent publication No. US 9,720,189B 1 (corresponding to taiwan patent publication No. M521746), the invention discloses an optical fiber connector, which includes a case body having two opposite sidewalls and a wiring portion, the opposite sidewalls are respectively provided with a sliding groove and a receiving groove located at the side of the wiring portion; a latch piece, which comprises a pull handle, a sliding element with two opposite extension arms and a resisting part positioned on each extension arm, wherein the pull handle can be rotatably connected with the sliding element, and each extension arm is slidably combined with the box body through each sliding chute; and a pair of resilient members, such as springs; wherein each extension arm is provided with an opening for each elastic element to be sleeved in, and the resisting part bends from one side of the opening and oppositely protrudes into the containing groove.

Because each spring is sleeved in the containing groove through the opening, one end of each spring is abutted against one end of the containing groove, and the other end of each spring is abutted against the abutting part. Therefore, if the spring is not properly positioned during installation, the spring may become jammed or dislodged from the opening during operation, causing unnecessary wear to the cartridge and even failure to slide.

Therefore, how to provide the springs with accurate positioning function is a problem to be overcome by those skilled in the art.

Each extension arm 21 is longitudinally provided with a stopping piece 212 in a protruding manner, and the sliding groove 13 is provided with a limiting groove 131 in a concave manner at a position corresponding to the stopping piece 212 for the stopping piece 212 to insert, so as to define an unlocking stroke of the sliding member 2 relative to the external pulling movement or an locking stroke of the internal retracting movement of the box body 1.

The optical fiber transmission module is technically characterized in that the top surface of the connecting sheet 22 and the bottom surface of the inserting part 12 are oppositely provided with an elastic body 25 and an abutting part 14; the elastic body 25 has a pair of elastic arms 251 on both sides, and the abutting member 14 includes a guiding portion 141, such as a guiding slope or a guiding convex pillar, symmetrically disposed on both sides for each elastic arm 251 to contact and move, so that the elastic body 25 can store or release energy during the moving process of the abutting member 14.

Referring to fig. 1 and 2, the elastic body 25 includes a pair of L-shaped pieces punched and bent on the top surface of the connecting piece 22, each of the L-shaped pieces has an elastic arm 251 extending toward the outer end of the connecting piece 22 and a flap 252 connected to the inner end of the connecting piece 22. The abutting member 14 is a trapezoidal protrusion protruding from the bottom surface of the inserting portion 12, and two sides of the trapezoidal protrusion are symmetrically and obliquely provided with a guiding portion 141, such as a guiding slope, for contacting each elastic arm 251.

The first embodiment of the fiber transmission module is assembled by assembling the box 1 and the sliding member 2 shown in fig. 1 and 2 to form a fiber transmission module shown in fig. 3, wherein the fiber transmission module can be latched and fixed in a connector socket 3 shown in fig. 4, and the box 1 is pulled out from the connector socket 3 by the sliding member 2.

As shown in fig. 7 and 8, when replacing or disassembling the optical fiber transmission module with other specifications, a user only needs to hold the pull handle 24 by hand to drive the sliding member 2 to move toward the opposite direction of the connector socket 3, so that the pair of resilient arms 251 of the resilient member 25 move outwards along the pair of guiding portions 141 to form an outwardly-extended energy storage type (shown in fig. 7). At this time, the stopping piece 212 of each extending arm 21 is inserted into the front end of the limiting groove 131 (shown in fig. 8) corresponding to the sliding groove 13 to define the displacement distance of the pair of elastic arms 251 along the pair of guiding portions 141, and the unlocking protrusion 23 at the end of each extending arm 21 pushes up the elastic locking piece 31 during the displacement process, so as to pull the fiber transmission module out of the connector receptacle 3.

When a new fiber optic transmission module is replaced and the slider 2 is released, the pair of resilient arms 251 are released and return to the original position along the pair of guides 141 to return the slider 2 to the locked position shown in fig. 4 and 5.

As shown in fig. 9 to 15, a second embodiment of the optical fiber transmission module is shown, and the same reference numerals (symbols) are used to indicate the same components as those in the first embodiment, and since the present embodiment shares many common components with the first embodiment, only the differences between the two embodiments will be described in detail later.

The difference between this embodiment and the first embodiment is that the elastic body 25 is attached to the connecting piece 22 by a single element, so as to obtain the same energy storage or release effect as the first embodiment.

As shown in fig. 9 and 10, the configurations of the abutting member 14 and the pair of guiding portions 141 are the same as those of the first embodiment, and are not repeated herein.

The positioning plate 253 can be fixed by riveting, screwing or buckling the positioning plate with the positioning groove 221. As shown in fig. 9 to 13, a possible embodiment of the positioning plate 253 buckled to the positioning groove 221 is provided, a first inserting piece 253a and a first inserting groove 253b are respectively disposed at the front end and the rear end of the positioning plate 253, and at least one buckle 253c is disposed between the first inserting piece 253a and the first inserting groove 253 b. A second insertion slot 221a for the first insertion piece 253a to be inserted, a second insertion piece 221b for the first insertion slot 253b to be inserted, and at least one fastening slot 221c for the at least one fastening hook 253c to be fastened are respectively arranged in the positioning slot 221 at positions corresponding to the first insertion piece 253a, the first insertion slot 253b and the at least one fastening hook 253c, so that the positioning piece 253 can be firmly connected and installed in the positioning slot 221 without being separated.

The second embodiment of the optical fiber transmission module is assembled by assembling the box 1 and the sliding member 2 shown in fig. 9 and 10 to form the optical fiber transmission module shown in fig. 11, the optical fiber transmission module can be latched and fixed in a connector socket 3 shown in fig. 4, and the box 1 is pulled out from the connector socket 3 by the sliding member 2.

As shown in fig. 14, the optical fiber transmission module is inserted into the connector receptacle 3, so that the pair of unlocking protrusions 23 at the rear ends of the pair of extension arms 21 are fastened to the pair of elastic locking pieces 31 oppositely disposed at two sides of the connector receptacle 3 to form a locking state; and the stopping piece 212 of each extending arm 21 is inserted into the rear end of the limiting groove 131 corresponding to the sliding groove 13 (see fig. 6).

As shown in fig. 15, when replacing or disassembling the optical fiber transmission module with other specifications, a user only needs to hold the pull handle 24 by hand to drive the sliding member 2 to move toward the opposite direction of the connector socket 3, so that the pair of elastic arms 251 of the elastic member 25 moves along the pair of guiding portions 141 to form an outwardly-extended energy storage type. At this time, the stopping piece 212 of each extending arm 21 is inserted into the front end of the limiting groove 131 (see fig. 8) corresponding to the sliding groove 13 to define the displacement distance of the pair of elastic arms 251 along the pair of guiding portions 141, and the unlocking protrusion 23 at the end of each extending arm 21 will jack up the elastic locking piece 31 during the displacement process, so as to pull the fiber transmission module out of the connector receptacle 3.

When a new fiber optic transmission module is replaced and the slider 2 is released, the pair of resilient arms 251 are released and return to the original position along the pair of guides 141 to return the slider 2 to the locked position shown in fig. 14.

As shown in fig. 16 to 18, a third embodiment of the optical fiber transmission module is shown, and the same reference numerals (symbols) are used to indicate the same components as those in the first embodiment, and since the present embodiment shares many common components with the first embodiment, only the differences between the two embodiments will be described in detail later.

The difference between this embodiment and the first embodiment is that the elastic body 25 is a W-shaped wire spring, and has a pair of spring arms 251 extending toward the outer end of the connecting piece 22 on both sides thereof, and an inverted V-shaped spring wire 254 connected between the pair of spring arms 251, and a connecting end of the V-shaped spring wire 254 forms a loop 255; the top surface of the connecting plate 22 is protruded with a tenon 222 for the ring 255 to fit, so as to bond the elastic body 25 to the connecting plate 22. The abutting member 14 is implemented as a pair of wedge-shaped protrusions protruding from the bottom surface of the inserting portion 12, and a guiding portion 141, such as a guiding slope, contacting each elastic arm 251 is symmetrically and obliquely arranged inside the pair of wedge-shaped protrusions.

As shown in fig. 17, the optical fiber transmission module is inserted into the connector receptacle 3, so that the pair of unlocking protrusions 23 at the rear ends of the pair of extension arms 21 are fastened to the pair of elastic locking pieces 31 oppositely disposed at two sides of the connector receptacle 3 to form a locking state; and the stopping piece 212 of each extending arm 21 is inserted into the rear end of the limiting groove 131 corresponding to the sliding groove 13 (see fig. 6). At this time, the pair of resilient arms 251 of the resilient body 25 contact the pair of guiding portions 141 of the abutting member 14 in the inclined inward-contracting form.

As shown in fig. 18, when replacing or disassembling the optical fiber transmission module with other specifications, a user only needs to hold the pull handle 24 by hand to drive the sliding member 2 to move toward the opposite direction of the connector socket 3, so that the pair of resilient arms 251 of the resilient member 25 move along the pair of guiding portions 141 to form a retracted energy storage type. At this time, the stopping piece 212 of each extending arm 21 is inserted into the front end of the limiting groove 131 (see fig. 8) corresponding to the sliding groove 13 to define the displacement distance of the pair of elastic arms 251 along the pair of guiding portions 141, and the unlocking protrusion 23 at the end of each extending arm 21 will jack up the elastic locking piece 31 during the displacement process, so as to pull the fiber transmission module out of the connector receptacle 3.

When a new fiber optic transmission module is replaced and the slider 2 is released, the pair of resilient arms 251 are released and return to the original position along the pair of guides 141 to return the slider 2 to the locked position shown in fig. 17.

As shown in fig. 19 to 21, a fourth embodiment of the optical fiber transmission module is shown, and the same reference numerals (symbols) are used to denote the same components as those in the third embodiment, and since the third embodiment shares many common components, only the differences between the two embodiments will be described in detail later.

The difference between this embodiment and the third embodiment is that the elastic body 15 is connected to the bottom surface of the inserting portion 12, so the representative symbol of the elastic body is changed to 15, the structure of the elastic body 15 is the same as that of the third embodiment, i.e. a W-shaped wire spring, both sides of which have a pair of spring arms 151 extending towards the inner end of the box body 1, and an inverted V-shaped spring wire 152 connected between the pair of spring arms 151, and a connection end of the V-shaped spring wire 152 forms a loop 153; the bottom surface of the insertion part 12 is provided with a tenon 122 for the sleeve ring 153 to engage, so that the elastic body 15 is combined with the bottom surface of the insertion part 12.

As shown in fig. 20, the optical fiber transmission module is inserted into the connector receptacle 3, so that the pair of unlocking protrusions 23 at the rear ends of the pair of extension arms 21 are fastened to the pair of elastic locking pieces 31 oppositely disposed at two sides of the connector receptacle 3 to form a locking state; and the stopping piece 212 of each extending arm 21 is inserted into the rear end of the limiting groove 131 corresponding to the sliding groove 13 (see fig. 6). At this time, the pair of elastic arms 151 of the elastic body 15 contact the pair of guiding portions 224 of the connecting piece 22 in the obliquely inward-retracted state.

As shown in fig. 21, when replacing or disassembling the optical fiber transmission module with other specifications, a user only needs to hold the pull handle 24 by hand to drive the sliding member 2 to move toward the opposite direction of the connector socket 3, so that the pair of resilient arms 151 of the resilient body 15 move along the pair of guiding portions 224 to form a retracted energy storage type. At this time, the stopping piece 212 of each extending arm 21 is inserted into the front end of the limiting groove 131 (see fig. 8) corresponding to the sliding groove 13 to define the displacement distance of the pair of elastic arms 151 along the pair of guiding portions 224, and the unlocking protrusion 23 at the end of each extending arm 21 will jack up the elastic locking piece 31 during the displacement process, so as to pull the fiber transmission module out of the connector receptacle 3.

When a new fiber optic transmission module is replaced and the slider 2 is released, the pair of resilient arms 151 are released and return to the original position along the pair of guides 224 to return the slider 2 to the locked position shown in fig. 20.

As shown in fig. 22 to 24, which show a fifth embodiment of the optical fiber transmission module, the same reference numerals (symbols) are used to denote the same components in this embodiment as compared with the first embodiment, and since the present embodiment shares many common components with the first embodiment, only the differences between the two will be described in detail later.

The difference between this embodiment and the first embodiment is that the elastic body 25 is a V-shaped wire spring, and both sides of the V-shaped wire spring have a pair of elastic arms 251 extending towards the inner end of the connecting piece 22, and a collar 255 formed by connecting ends of the pair of elastic arms 251; the top surface of the connecting plate 22 is protruded with a tenon 222 for the ring 255 to fit, so as to bond the elastic body 25 to the connecting plate 22. The abutting member 14 is a pair of long bumps protruding from the bottom of the inserting portion 12, and the inner ends of the long bumps are symmetrically and obliquely provided with a guiding portion 141, such as a guiding slope, for each elastic arm 251 to contact.

As shown in fig. 23, the optical fiber transmission module is inserted into the connector receptacle 3, so that the pair of unlocking protrusions 23 at the rear ends of the pair of extension arms 21 are fastened to the pair of elastic locking pieces 31 oppositely disposed at two sides of the connector receptacle 3 to form a locking state; and the stopping piece 212 of each extending arm 21 is inserted into the rear end of the limiting groove 131 corresponding to the sliding groove 13 (see fig. 6). At this time, the pair of resilient arms 251 of the resilient body 25 contact the pair of guiding portions 141 of the abutting member 14 in the inclined inward-contracting form.

As shown in fig. 24, when replacing or disassembling the optical fiber transmission module with other specifications, a user only needs to hold the pull handle 24 with his hand to drive the sliding member 2 to move toward the opposite direction of the connector socket 3, so that the pair of resilient arms 251 of the resilient member 25 move along the pair of guiding portions 141 to form a retracted energy storage type. At this time, the stopping piece 212 of each extending arm 21 is inserted into the front end of the limiting groove 131 (see fig. 8) corresponding to the sliding groove 13 to define the displacement distance of the pair of elastic arms 251 along the pair of guiding portions 141, and the unlocking protrusion 23 at the end of each extending arm 21 will jack up the elastic locking piece 31 during the displacement process, so as to pull the fiber transmission module out of the connector receptacle 3.

When a new fiber optic transmission module is replaced and the slider 2 is released, the pair of resilient arms 251 are released and return to the original position along the pair of guides 141 to return the slider 2 to the locked position shown in fig. 23.

As shown in fig. 25 to 27, which show a sixth embodiment of the optical fiber transmission module, the same reference numerals (symbols) are used to denote the same components as those in the fifth embodiment, and since the fifth embodiment shares many common components, only the differences between the two embodiments will be described in detail later.

The difference between this embodiment and the fifth embodiment is that the elastic body 15 is connected to the bottom surface of the inserting part 12, so the representative symbol of the elastic body is changed to 15, the structure of the elastic body 15 is the same as that of the fifth embodiment, i.e. a V-shaped wire spring, both sides of which have a pair of elastic arms 151 extending towards the front end of the box body 1, and a collar 153 formed by connecting ends of the pair of elastic arms 151; the bottom surface of the insertion part 12 is provided with a tenon 122 for the sleeve ring 153 to engage, so that the elastic body 15 is combined with the bottom surface of the insertion part 12. The abutting member is implemented as a guiding portion 225, such as a guiding protrusion, protruding from the top surface of the connecting piece 22 and contacting the pair of elastic arms 151 respectively.

As shown in fig. 26, the optical fiber transmission module is inserted into the connector receptacle 3, so that the pair of unlocking protrusions 23 at the rear ends of the pair of extension arms 21 are fastened to the pair of elastic locking pieces 31 oppositely disposed at two sides of the connector receptacle 3 to form a locking state; and the stopping piece 212 of each extending arm 21 is inserted into the rear end of the limiting groove 131 corresponding to the sliding groove 13 (see fig. 6). At this time, the pair of elastic arms 151 of the elastic body 15 touch the pair of guide portions 225 of the connection piece 22.

As shown in fig. 27, when replacing or disassembling the optical fiber transmission module with other specifications, a user only needs to hold the pull handle 24 by hand to drive the sliding member 2 to move toward the opposite direction of the connector socket 3, so that the pair of resilient arms 151 of the resilient body 15 move along the pair of guiding portions 225 to form a retracted energy storage type. At this time, the stopping piece 212 of each extending arm 21 is inserted into the front end of the limiting groove 131 (see fig. 8) corresponding to the sliding groove 13 to define the displacement distance of the pair of elastic arms 151 along the pair of guiding portions 225, and the unlocking protrusion 23 at the end of each extending arm 21 will jack up the elastic locking piece 31 during the displacement process, so as to pull the fiber transmission module out of the connector receptacle 3.

When a new fiber optic transmission module is replaced and the slider 2 is released, the pair of resilient arms 251 are released and return to the original position along the pair of guides 141 to return the slider 2 to the locked position shown in fig. 20.

As shown in fig. 28 to fig. 31, which show a seventh embodiment of the optical fiber transmission module, the same reference numerals (symbols) are used to denote the same components in this embodiment as compared with the previous embodiments, and since the present embodiment shares many common components with the previous embodiments, only the differences between the two embodiments will be described in detail later.

This embodiment is illustrated using the second embodiment, and a bail 26 is substituted for the pull handle 24 of the second embodiment. The bail 26 includes a pair of arms 261, and a pick 262 connecting the pair of arms 261, the pair of arms 261 having a pair of axle holes 261a pivotally connected to the pair of pivots 111 of the pair of sidewalls 11, and a pair of arc-shaped elongated slots 261b sleeved on the pair of fixing axles 213 at the front ends of the pair of extension arms 21. The pair of shaft holes 261a of the pair of arms 261 are pivotally connected to the pair of pivots 111 of the pair of side walls 11, and the pair of arc-shaped elongated slots 261b are sleeved on one end, for example, the lower end, of the pair of fixing shafts 213, so as to form an assembled perspective view of the seventh embodiment of the fiber transmission module shown in fig. 29 and 30.

A distance difference between each of the arc-shaped long grooves 261b and the corresponding two end portions, for example, the upper end portion and the lower end portion of the fixed shaft 213; when the pulling piece 262 of the bail 26 is turned to rotate the pair of fixing shafts 213 from the lower end to the upper end of the pair of arc-shaped elongated slots 261b, the sliding member 2 is pulled to displace toward the opposite direction of the connector socket 3, so that the unlocking protrusion 23 at the end of each extension arm 21 will jack up the elastic locking piece 31 during the displacement process, so as to pull the fiber transmission module away from the connector socket 3.

Therefore, according to the embodiment of the invention, the elastic body and the abutting part can form a stable and accurate positioning effect, so that the situation that the existing spring is clamped or separated can not be caused in the process of generating energy storage or energy release in the displacement process of the pair of guide parts by the pair of elastic arms, thereby improving the production yield of the optical fiber transmission module, which is an unprecedented preferred structure of the similar articles.
