Description

Technical Field

[0001] The utility model belongs to the technical field of photoelectric signal transmission, and in particular relates to a photoelectric hybrid connector socket and a connector assembly. Background Art

[0002] With the rapid increase in data throughput from network terminals, network bandwidth needs to be upgraded to 10Gbps. Optical fiber and CAT6A cables can both meet this 10Gbps bandwidth requirement, but Category 6 cables are bulky and heavy, limiting transmission distances. Passive optical fiber access reduces network construction costs and offers significant advantages, such as its compact size and light weight. However, all-optical solutions replacing network cables face power supply challenges.

[0003] The current optimal solution is to connect terminals and switches via optoelectronic composite connectors. Leveraging the advantages of optical fiber long-distance transmission and cable power supply, this approach can achieve 300-meter power supply and 10Gbps access bandwidth. Furthermore, optical fiber networks can support bandwidths exceeding 10G, allowing for straightforward upgrades and evolution over the next several years.

[0004] In view of the trend of integration and miniaturization of terminal AP equipment, it is necessary to develop miniaturized optoelectronic hybrid sockets for terminal access to realize a miniaturized solution that integrates optical fiber data transmission and power supply.

[0005] In the related prior art, the existing ESC adapter is as follows Figure 1 As shown, the first end is connected to the ESC connector 400, and the second end is connected to the SC connector 500. Power is provided through the ESC connector and pins, and optical fiber communication is achieved by docking the ESC connector 400 and the SC connector 500. It can support a pair of connectors for optical signal transfer and onboard power supply. However, this type of product still has the following problems: the SC connector connected to the second end has limited space inside the device and cannot meet the installation space length requirement. During installation, the SC connector connected to the second end is too long (essentially, the length from pin 450 to the end of the SC connector 500 is longer based on the position of pin 450 of the ESC adapter), which can easily interfere with other electronic components in the chassis. Existing ESC-BOSA adapters such as Figure 2As shown, the first end of the ESC-BOSA adapter is connected to the ESC connector 600, and the second end is connected to the BOSA device 700. Power is supplied through the ESC connector and pins, and photoelectric conversion is achieved by docking the ESC connector 600 and the BOSA device 700. The ESC-BOSA adapter can support a pair of connector optical signal transfer and on-board power supply. This type of product still has the following problems: Although the existing ESC-BOSA adapter shortens the distance between the connectors (the distance from the pin 750 to the end of the BOSA device 700), it is limited by the BOSA opening pins on the PCB panel and is not compatible with the existing ONU terminal equipment PCB board requirements. The structure on the PCB board needs to be redesigned. The pins reserved for BOSA on the existing ONU complete equipment PCB board are fixed. For many equipment manufacturers, on the one hand, they lack the ability to design PCB board circuits, and on the other hand, they are not very willing to change the PCB board circuits. In other words, Figure 2 Since the position of pin 750 is fixed, when the ESC connector 600 and the BOSA device 700 are connected, the position of the pin 750 led out from the lower end is fixed. When the PCB circuit is not changed, Figure 2 Pin 750 is far away from the BOSA pin of the existing whole machine PCB board and cannot meet the connection requirements of power transmission.

DETAILED DESCRIPTION

[0039] The present invention is described in detail below by way of exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may also be beneficially combined in other embodiments.

[0040] It should be noted that: unless otherwise defined, the technical terms or scientific terms used herein shall have the usual meanings understood by persons having ordinary skills in the field to which the present utility model belongs. The words "one", "an" or "the" and the like used in the specification and claims of the present utility model patent application do not express quantitative limitations, but rather indicate the presence of at least one. Words such as "include" or "comprise" indicate that the elements or objects appearing before "include" or "comprises" include the elements or objects listed after "include" or "comprises" and their equivalents, but do not exclude other elements or objects with the same function.

[0041] As shown in the figure, this solution provides an optoelectronic hybrid connector socket, including an outer shell 1, a claw bracket 2 and a contact piece. A cavity 17 with two through ends is formed in the outer shell 1. The cross section of the cavity 17 is a rectangular cavity structure. The two ends of the cavity 17 serve as the first plug-in port 171 and the second plug-in port 172 of the socket respectively. One end of the claw bracket 2 is inserted into the second plug-in port 172 and installed in the cavity 17 for locking and fixing with the optical fiber connector 200. The other end of the claw bracket 2 is used for locking and fixing with the optical fiber ferrule 300. The optical fiber ferrule 300 is a standard bare pin. This solution can achieve the docking of the standard optoelectronic hybrid adapter and the standard bare pin by redesigning the claw structure of the second end of the claw bracket 2 on the interface of the standard optoelectronic hybrid adapter. The space required for docking of the second end of the traditional optoelectronic hybrid adapter is reduced by the first distance length ( Figure 1 The vertical distance from the middle pin part to the end of the SC connector is shortened to the second distance length ( Figure 3 The contact piece is the conductive piece 3 shown in the figure. The conductive piece 3 is disposed inside the cavity 17 and symmetrically on both sides of the claw bracket 2 to achieve electrical connection of the optical fiber connector 200. The conductive piece 3 includes a spring contact 32 arranged along the plug-in direction of the socket and a pin 33 arranged perpendicular to the plug-in direction.

[0042] In this solution, the optical fiber connector 200 includes different types of adapter connectors such as ESC connectors and SC connectors, wherein the optical fiber connector 200 includes a plug outer shell 203 that is structurally adapted to its first plug port 171. An optical fiber ferrule Ⅰ 201 is provided inside the plug outer shell 203, and an outer wall card groove 202 is symmetrically provided on the outer wall of the plug outer shell 203. The plug outer shell 203 is inserted into the cavity 17 of the outer shell 1 by the first plug port 171, and the outer shell 1 is connected to the outer shell 1 through the inner shell. The internal claw bracket 2 cooperates with the outer wall slot 202 to clamp and fix the plug outer shell 203, thereby ensuring the connection stability between the optoelectronic hybrid connector socket 100 and the optical fiber connector 200. The optical fiber ferrule 300 includes an optical fiber ferrule component II 301 and a ferrule tail seat 302. The optical fiber ferrule component II 301 includes a ferrule body. The ferrule body has a hole for installing an optical fiber along the central axis. The tail end of the ferrule body is fixed to the ferrule tail seat 302. A flange groove 303 is provided on the outer circumferential surface of the ferrule tail seat 302.

[0043] In this solution, the claw bracket 2 can adopt the following structure: The first embodiment is that the claw bracket 2 includes a bracket base 21, a hook claw assembly I 21 and a hook claw assembly II 22 arranged on the bracket base 21. The hook claw assembly I 21 and the hook claw assembly II 22 are respectively arranged on the opposite side end surfaces of the bracket base 23 and are integrally formed with the bracket base 23. Specifically, the hook claw assembly I 21 is located inside the cavity 17 after being installed in place, and the hook claw assembly II 22 extends from the mounting base 23 to the outside of the cavity 17 and is located outside the cavity 17. The function of the hook claw assembly I 21 is to achieve locking and fixation with the outer wall card groove 202 of the optical fiber connector 200, and the function of the hook claw assembly II 22 is to achieve locking and anti-rotation fixation with the flange groove 303 of the optical fiber ferrule 300. The second embodiment differs from the first embodiment in that: the hook assembly I21 and the hook assembly II22 are respectively arranged on the opposite side end faces of the bracket seat 23, and are designed to be split from the bracket seat 23. For example, the hook assembly I21, the hook assembly II22 and the bracket seat 23 are assembled into one by means of card connection, forced installation or bonding fixation. The third embodiment differs from the first embodiment in that: the hook assembly II22 is still located in the cavity 17, and the connection between the hook assembly II22 and the optical fiber ferrule 300 is realized in the cavity 17.

[0044] In this solution, a central sleeve 24 is further provided on the bracket seat 21, and a ceramic sleeve 4 is nested in the central sleeve 24. The optical fiber ferrule part I 201 and the optical fiber ferrule part II 301 of the optical fiber connector 200 are inserted and docked in the tube cavity of the ceramic sleeve 4 to realize optical signal coupling transmission.

[0045] In this embodiment, the claw assembly I21 of the claw bracket 2 is a straight claw 211, and a pair of straight claws 211 are vertically arranged on the front end surface of the bracket seat 21 and are arranged opposite to each other. The length direction of the straight claw 211 is consistent with the axial direction of the center sleeve 24, and a locking clamping platform 213 is formed on the opposite side of the end of the straight claw 211. The locking clamping platform 213 of the straight claw 211 is locked and connected with the outer wall clamping groove 202 of the optical fiber connector 200. A clamping groove II 212 is respectively provided on the opposite side of the locking clamping platform 213 at the end of the straight claw 211. The clamping groove II 212 is used to avoid and accommodate the spring contact member 32 of the conductive sheet 3, and is arranged on the outer shell as shown in FIG. Figure 10 The positive and negative directions of A shown in the figure limit the position of the spring contact 32. The slot II 212 adopts a bevel groove structure to cooperate with the middle section structure of the spring contact 32. The hook assembly II 22 can adopt an oblique hook 212 as shown in the figure. The two oblique hooks 212 are relatively arranged on the rear end face of the bracket seat 21. The length setting direction of the oblique hook 212 is not parallel to the axial direction of the center sleeve 24, and the distance from the root to the head end of the two oblique hooks 212 gradually narrows, that is, the two oblique hooks 212 gradually approach each other from the connecting end to the free end. A reinforcement block 223 is provided on the outside of the connecting end of the oblique hook 212 to improve the structural strength of the connecting end of the oblique hook 212. The cam 222 is provided on the opposite side of the free clamping end of the oblique hook 212, and the anti-rotation boss 222 is configured to cooperate with the optical fiber flange 302 of the optical fiber ferrule 300. A flange groove 303 that cooperates with the anti-rotation boss 222 is formed on the outer circumference of the optical fiber flange 302, and the anti-rotation boss 222 can be snapped into the flange groove 303 to achieve locking and fixing of the optical fiber ferrule 300 and prevent the optical fiber ferrule 300 from rotating. In an embodiment not shown in the figures, the hook assembly II can also adopt a straight hook, that is, the straight hook of the hook assembly II is perpendicular to the bracket seat 21, and an anti-rotation boss 222 is provided on the opposite side of the free clamping end. The anti-rotation boss 222 is configured to cooperate with the optical fiber flange 302 of the optical fiber ferrule 300, and a groove 303 that cooperates with the boss is formed on the outer circumference of the optical fiber flange 302, so that the anti-rotation boss 222 is snapped into the flange groove 303 to achieve locking and fixing and anti-rotation of the optical fiber ferrule 300.

[0046] In this embodiment, the central sleeve 24 is a hollow cylindrical structure, and a plurality of claws 241 are arranged around the two ends of the central sleeve 24. The claws 241 are used to axially limit the ceramic sleeve 4 at both ends after the ceramic sleeve 4 is inserted into the central sleeve 24. In this solution, the claws 241 at each end are a three-petal structure, and the ceramic sleeve 4 can be directly inserted into the central sleeve 24 of the claw bracket 24 from both ends to achieve axial fixation.

[0047] In the scheme, the claw bracket 2 and the shell body 1 are connected by snap fit, specifically, the structure shown in the figure can be used, the two sides of the bracket seat 21 are provided with clamping blocks 26, the front end side of the clamping block 26 is formed with a clamping inclined surface, so that the claw bracket 2 is smoothly clamped into the shell body 1, and the clamping groove Ⅰ11 is formed on the opposite two side walls of the shell body 1, which can be a through hole groove as shown in the figure, or a blind groove (not shown in the figure) can be arranged on the inner wall of the cavity of the shell body 1. Or in an embodiment not shown in the figure, the inner side walls of the opposite two sides of the shell body 1 are provided with clamping blocks, and the two sides of the bracket seat 21 are provided with clamping grooves matched with the clamping blocks. This structure can also achieve snap fit fixing.

[0048] In the scheme, the two sides of the bracket seat 21 provided with the clamping blocks 26 are also formed with packaging steps 27, and the conductive sheet 3 is provided with a through hole 31, which plays a role of giving way when the conductive sheet 3 is installed, so that the clamping block 26 on the bracket seat 21 can smoothly enter the clamping groove Ⅰ11 of the shell body 1 to achieve snap fit connection, and the through hole 31 also plays a role of limiting and fixing the conductive sheet 3. The packaging step 27 can block the second plug-in port 172 of the cavity 17 of the shell body 1, so that the inside and outside of the second plug-in port 172 are isolated during installation, so as to isolate the main part of the conductive sheet 3 from the outside.

[0049] In the embodiment, the bracket seat 21 is also provided with a stop table Ⅱ28, and the stop table Ⅱ28 of the bracket seat 21 cooperates with the stop table Ⅰ14 arranged on the inner side wall of the shell body 1, and the stop surface of the stop table Ⅰ28 abuts against the stop surface of the stop table Ⅰ14, so as to limit the position of the claw bracket 2 inserted into the cavity 17 from the second plug-in port 172 to the front end direction.

[0050] As shown in the figure, in this embodiment, a clearance groove 12 corresponding to the spring contact member 32 of the conductive sheet 3 is formed on the inner walls on opposite sides of the outer shell 1, and a card slot III 13 is provided on the clearance groove 12 near the first plug port 171. The card slot III 13 is opened at the first plug port and is located on the inner side wall of the outer shell 1. Specifically, the card slot III 13 is a hook groove formed by a shell similar to a barb. The opening direction of the card slot III 13 is set relative to the extension direction of the spring contact member 32. The purpose of setting the card slot III 13 is: the end of the spring contact member 32 is formed with a relatively bent spring structure, and the end of the spring structure extends The conductive sheet 3 is inserted into the recess 12 and is confined in the slot III 13 in the recess 12. A mounting slot 15 is formed on the other side wall of the outer shell 1 for inserting the pin 33 of the conductive sheet 3 when installing. The mounting slot 15 is opened along the axial direction of the outer shell 1 by the edge of the port at one end. When the conductive sheet 3 is installed in the cavity 17, the pin 33 is inserted into the opening of the mounting slot 15. The pin 33 is exposed outward from the mounting slot 15 of the outer shell 1 and is conductively connected to the PCB board. In this solution, the pin 33 can adopt a straight pin structure as shown in the figure, or a fisheye structure pin.

[0051] In this solution, a fixed arm 18 is also provided on the end face of the outer shell 1 where the mounting slot 15 is provided. The fixed arm 18 includes two elastic arms arranged opposite to each other, with a gap formed between the two elastic arms. An anti-slip head is formed at the end of the fixed arm 18. When the fixed arm 18 needs to be installed and inserted into the fixing hole of the PCB board, the two elastic arms are pressed close together so that the gap becomes smaller. After being inserted into the fixing hole, the elastic arm is deformed and reset. Due to the action of the anti-slip head, the outer shell 1 is fixed at the corresponding fixing hole.

[0052] In this solution, the optical fiber connector 200 of the embodiment shown in the figure takes the ESC connector as an example. A guide groove 16 is further provided on the side wall of the outer shell 1 opposite to the end face where the mounting slot 15 is provided. The guide groove 16 is used to guide the docking of the optical fiber connector 200. A guide block 204 that cooperates with the guide groove 16 is formed on the outer side wall of the optical fiber connector 200. The first plug-in port 171 is defined as the front end of the outer shell 1, and the second plug-in port 172 is defined as the rear end of the outer shell. When the optical fiber connector 200 is plugged in from the first plug-in port 171 to the rear end of the outer shell 1, the guide block 204 cooperates with the guide groove 16 to guide the plug-in direction. At the same time, the guide groove 16 also serves to limit the plug-in depth of the optical fiber connector 200.

[0053] After the plug connector 51 is inserted into the cavity 17 of the outer shell 1, the cap 52 is sealed at the first plug port 171 of the outer shell 1, so as to effectively protect the port of the connector socket and prevent external impurities such as dust from entering.

[0054] In a typical embodiment of the present invention, a connector assembly is provided, including the optoelectronic hybrid connector receptacle described in the above embodiment. The first plug-in port 171 of the optoelectronic hybrid connector receptacle 100 is adapted to connect with the optical fiber connector 200, and the second plug-in port 172 is adapted to connect with the optical fiber ferrule 300. The optical fiber ferrule component I 201 of the optical fiber connector 200 and the optical fiber ferrule component II 301 of the optical fiber ferrule 300 extend from the front and rear plug-in ports of the optoelectronic hybrid receptacle 100, respectively, and enter the interior of the central sleeve 24. They are guided and mated within the ceramic sleeve 4 to achieve optical signal coupling and transmission. In this embodiment, the hook assembly I 21 is engaged and locked with the outer wall groove 202 of the optical fiber connector 200, and the hook assembly II 22 is engaged and locked with the flange groove 303 of the optical fiber ferrule 300 to prevent rotation. The optical fiber connector 200 is electrically connected to the PCB board through the pin 33 of the conductive plate 3, thereby achieving power transmission of the optical fiber connector 200. Through the above means, this embodiment realizes the integrated functions of optical fiber data transmission and power supply of the connector receptacle. It should be noted that the tail end of the optical fiber ferrule 300 is connected to the BOSA device 700 ( Figure 3 After that, the pin 750 (not shown) of the BOSA device 700 can be adjusted by the bridging effect of the optical fiber ferrule 300. Figure 3 The distance between the pins of the PCB and the PCB is not shown, so that the two can be better connected adaptively, thus solving the problem of Figure 2 The structure is not well compatible with the requirements of existing ONU terminal equipment PCB boards.

[0055] The above merely describes preferred embodiments of the present application and is not intended to limit the present application in any form. Although the present application has been disclosed with preferred embodiments, it is not intended to limit the present application. Any skilled person in the art can make minor changes or modifications to the disclosed technical content without departing from the technical solution of the present application, and any simple modification, equivalent change and modification of the above embodiments based on the technical essence of the present application still belong to the scope of the technical solution of the present application.
