Description

Technical Field

[0002] Optoelectronic connectors are devices used to connect optical fibers, which play the role of connecting and fixing optical fibers. The main function of optoelectronic connectors is to maximize the transmission effect of optical signals between optical fibers while ensuring the stability and reliability of transmission. Optoelectronic connectors have a wide range of applications, including optical communications, optical sensing, beam shaping and other fields. To a certain extent, optoelectronic connectors also affect the reliability and performance of optical transmission. As people's requirements for the signal transmission capacity of optical fiber networks continue to increase, in addition to innovating in network transmission methods, the reliability and stability of optical fiber network signal transmission can also be improved by changing the reliability and stability of the connection between optoelectronic connectors and optoelectronic equipment, avoiding the reduction of transmission performance of optical fiber networks due to unstable connections.

[0003] At present, the photoelectric connectors are all equipped with conductive plates, which are electrically connected to the wires to realize optical fiber network communication. The existing conductive plates are usually set on one surface of the photoelectric splitter. However, in this way, when the photoelectric connector is displaced, poor contact or no contact may occur, resulting in reduced connection reliability of the photoelectric connector. In addition, the existing photoelectric connectors are complex in design. In order to avoid assembly errors during the production and assembly process, certain technical requirements are imposed on the assemblers, which is not conducive to improving production efficiency of enterprises. For this reason, it is necessary to design a photoelectric connector with strong connection reliability, simple structure and easy assembly. Utility Model Content

The second conductive portion 22 extends along the length direction of the second contact surface 12 to its tail end. Among them, Figure 1 In the viewing angle, the direction where the mark A is located is the head (front end) of the photoelectric connector, and the direction where the mark B is located is the tail end of the photoelectric connector. It should be noted that for the first contact surface 11, Figure 1 In the perspective of , it is the top surface. When it is reversed, the first contact surface 11 is the bottom surface. Whether it is the top surface or the bottom surface can be defined according to the actual use scenario and is not specifically limited here. For the convenience of description, this article uses Figure 1 The top surface in the perspective of FIG. 1 is used as a reference surface to explain the optoelectronic connector.

[0038] Among them, the tail end of the second contact surface 12 is the end close to the direction of the mark B (also the end direction of the second conductive part 22). A bent fixing part 23 is provided at the tail end of the second conductive part 22, and the fixing part 23 is bent outward of the inner core 1 in an arc shape. When in use, the fixing part 23 is connected to the inserted wire, and the wire passes through the bend and is fixedly connected to the outer side of the fixing part 23, which effectively improves the line connection of the optoelectronic connector and avoids problems such as disconnection or poor contact of the connecting line of the optoelectronic connector caused by pulling the wire. In addition, due to the simple structure of the optoelectronic connector, the technical requirements for production personnel to assemble the optoelectronic connector are reduced during the assembly process.

[0039] In this embodiment, a strip-shaped protrusion 3 extending along the length direction of the first contact surface 11 is provided at the junction between the first contact surface 11 and the second contact surface 12 of the inner core 1 , and the first conductive portion 21 is buckled on the strip-shaped protrusion 3 .

[0040] Specifically, the strip-shaped protrusion 3 is arranged at the middle of the first contact surface 11 of the inner core 1 and close to the edge of the second contact surface 12, that is, the side wall. The first conductive portion 21 is concave to form a strip-shaped opening groove. When installed, the strip-shaped opening 524 groove is buckled on the strip-shaped protrusion 3 and fixedly connected to the inner core 1 to ensure that the conductive sheet 2 does not move.

[0041] like Figure 3 As shown, the conductive sheet 2 further includes a first connecting member 24 , and the first connecting member 24 connects the first conductive portion 21 and the second conductive portion 22 perpendicularly to the length direction of the inner core 1 .

[0042] Specifically, the first connector 24 is disposed on the side wall of the outer wall of the inner core 1, that is, on the second contact surface 12, and is bent toward the inner direction of the inner core 1 and is disposed perpendicular to the length direction of the inner core 1, and is used to connect the first conductive part 21 and the second conductive part 22 together. Among them, a groove 16 for accommodating the first connector 24 is also provided on the outer wall of the inner core 1. During installation, the first connector 24 is embedded in the groove 16 and fixed on the outer wall of the inner core 1, thereby improving the stability of the conductive sheet 2 and the inner core 1. The first connector 24 connects the second conductive part 22 and the second conductive part 22 as a whole, so that the potentials of the two are consistent, thereby improving the stability of the electrical connection of the photoelectric connector.

[0043] In this embodiment, the second conductive part 22 includes a second connecting member 221 and a third connecting member 222. The end of the second connecting member 221 close to the head position of the inner core 1 is bent toward the inner core 1. A accommodating groove 14 for accommodating the bending of the second connecting member 221 is provided at a position corresponding to the bending of the second connecting member 221 on the inner core 1.

[0044] Specifically, the front end of the second conductive part 22, i.e., the end in the direction of the mark A, is bent toward the inner direction of the inner core 1, and cooperates with the corresponding receiving groove 14 on the outer wall of the inner core 1, so that the first connecting member 24 is buckled on the outer wall of the inner core 1. In addition, a fixing groove 15 for fixing the third connecting member 222 is provided at a position corresponding to the third connecting member 222 on the inner core 1; the tail end of the second connecting member 221 is recessed toward the inner core 1 and connected to the third connecting member 222, and the tail end of the third connecting member 222 is connected to the bent fixing part 23.

[0045] Among them, a recessed groove 17 is provided at the tail end of the inner core 1 and on the surface where the third connecting member 222 is located, and the tail end of the second connecting member 221 is recessed toward the inner core 1, so that the third connecting member 222 is accommodated in the recessed groove 17. A convex fixing groove 15 is provided at a position corresponding to the third connecting member 222 in the recessed groove 17, which is used to fix and limit the third connecting member 222 to prevent the third connecting member 222 from moving, thereby improving the stability of the connection between the second conductive part 22 and the inner core 1.

[0046] like Figure 5 , 6 As shown, the connector body is provided with a stopper assembly 5 , which includes a fixing sleeve 51 through which the optical fiber is passed and a blocking portion 52 connected to the fixing sleeve 51 , and the inner core 1 is sleeved outside the fixing sleeve 51 .

[0047] Specifically, the fixing sleeve 51 is arranged at the front end of the stopper assembly 5, and is preferably a hollow cylindrical structure. The optical fiber passes through the hollow channel in the fixing sleeve 51, and the inner core 1 is sleeved on the fixing sleeve 51. The connector body is also provided with a ceramic pin 7 and a spring 8. A clamping seat 71 is provided in the middle of the ceramic pin 7, and one end of the spring 8 abuts against the clamping seat 71. When in use, one end of the ceramic pin 7 and the spring 8 are inserted into the fixing sleeve 51 together. When the inner core 1 is sleeved outside the fixing sleeve 51, the front end of the ceramic pin 7 leaks out of the inner core 1.

[0048] The fixing sleeve 51 is provided with a first opening groove 512 and a second opening groove 513 facing the ceramic pin 7. When installed, the tail end of the ceramic pin 7 is accommodated in the first opening groove 512, and the middle part of the ceramic pin 7 is accommodated in the second opening groove 513 together with the spring 8. The diameter of the second opening groove 513 is larger than the first opening groove 512, and the end of the spring 8 away from the ceramic pin holder 71 abuts against the limiting wall 514 of the second opening groove 513. When the photoelectric connector is inserted into the adapter, the ceramic pin 7 is subjected to resistance, and the holder 71 compresses the spring 8 and moves toward the fixing sleeve 51; when the photoelectric connector is detached, the spring generates elastic force to push the holder 71 to drive the ceramic pin 7 to move toward the front end (in the direction marked A).

[0049] like Figure 6 As shown, the blocking portion 52 is provided with a dividing groove 521, and a hole 522 connected to the fixing sleeve 51 is provided in the dividing groove 521; a wire groove 523 is arranged oppositely in the dividing groove 521, and one end of the wire groove 523 is connected to the side wall of the dividing groove 521 to form an opening 524.

[0050] Specifically, the wire splitting groove 521 is used to separate the optical fiber and at least two wires in the optoelectronic hybrid cable, and the optoelectronic hybrid cable is inserted into the optoelectronic connector from the direction where the mark B is located to the direction where the mark A is located. After the optoelectronic hybrid cable is stripped, the optical fiber passes through the hole 522 connected to the fixing sleeve 51 and is connected to the ceramic pin 7 contained in the fixing sleeve 51, so as to realize the optical communication of the optoelectronic connector. There are preferably two wires, and the two wires are accommodated in the wire grooves 523 arranged opposite to each other, and pass through the opening 524 to be connected to the fixing part 23 on the conductive sheet 2. After the wire passes between the fixing part 23 and the third connecting member 222 (i.e., the bending part of the fixing part 23), it is bent outward and fixedly connected to the outer wall of the fixing part 23, and the connection method is preferably welding. The optoelectronic connector separates the optical fiber and the wire through the wire splitting groove 521, which improves the reliability of the connection between the wire and the optical fiber and also improves the assembly efficiency of the optoelectronic connector.

[0051] In this embodiment, a guide protrusion 511 extending along the length direction of the fixing sleeve 51 is provided on the fixing sleeve 51 .

[0052] Specifically, a guide groove 18 is provided on the first contact surface 11 of the inner core 1 . During installation, the guide protrusion 511 cooperates with the guide groove 18 to limit the moving position of the inner core 1 and prevent the fixing sleeve 51 from rotating in the inner core 1 .

[0053] like Figure 7 As shown, one end of the blocking portion 52 connected to the fixing sleeve 51 is provided with a limiting step 9 toward the inner core 1. The inner core 1 is sleeved outside the fixing sleeve 51, and its rear end abuts against the limiting step 9 to limit the displacement of the blocking portion 52 inserted into the inner core 1, thereby improving installation efficiency.

[0054] like Figure 8 As shown, the connector body also includes a tail sleeve 6 sleeved on the blocking part 52, a positioning buckle 525 is provided on the blocking part 52, a positioning hole 61 matching the positioning buckle 525 is provided on the tail sleeve 6, a moving mark 62 is provided on the tail sleeve 6, and a threading hole 63 facing the blocking part 52 is provided at its tail end.

[0055] Specifically, during assembly, the displacement mark 62 on the tail sleeve 6 can remind the assembler of its moving direction, which can further improve production efficiency, and the assembler can also judge the front and back of the tail sleeve 6 by the displacement mark, which reduces the probability of assembly errors and improves assembly efficiency. When it reaches the position of the blocking part 52, the positioning buckle 525 on the blocking part 52 cooperates with the positioning hole 61 on the tail sleeve 6 to fix the tail sleeve 6 outside the blocking part 52 to improve the stability of the connection between the blocking part 52 and the tail sleeve 6. At the threading hole 63 at the tail end of the tail sleeve 6 facing the blocking part 52, the optical-electric hybrid cable can enter the branching groove 521 of the blocking part 52 by threading.

[0056] like Fig. 9 As shown, the connector body also includes a jacket 10 sleeved on the inner core 1 , and the jacket 10 is provided with an opening at a position corresponding to the conductive sheet 2 , and the conductive sheet 2 is exposed in the opening; a positioning block 110 is also provided on the jacket 10 .

[0057] Specifically, the conductive sheet 2 located on the first contact surface 11 and the second contact surface 12 contacts the conductive point on the corresponding adapter through the opening. During installation, the inner wall of the jacket 10 corresponding to the fixing portion 23 presses the wire onto the second connector 221 through the fixing portion 23 and fits it tightly. The positioning block 110 on the jacket 10 is used to limit the displacement of the optoelectronic connector when it is inserted into the corresponding adapter.

[0058] Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
