Description

Technical Field

[0001] The present invention belongs to the technical field of connectors, and in particular relates to a quick plug-in integrated optical fiber connector. Background Art

[0002] In the field of optical communications, optical backplane connectors are key components for optical signal transmission. Their connection reliability and operational convenience directly affect system stability and maintenance efficiency.

[0003] Traditional structures rely on the assembly and positioning of multiple components, which can easily lead to fiber ferrule misalignment and poor end-face contact due to accumulated tolerances, resulting in increased optical loss or signal interruption. This significantly increases the risk of connection failure, especially under complex conditions such as vibration and shock. Complex structures require specialized tools or multi-step alignment, resulting in time-consuming and inefficient maintenance, making it difficult to meet the needs of rapid deployment and replacement of high-density backplane systems. Summary of the Invention

[0004] The present invention aims to solve the problems in the prior art and proposes the following technical solutions:

[0008] The socket housing has a guide groove and an extrusion groove respectively formed in the middle and inner wall edge of the socket housing, and an abutment plate is integrally connected to the inner edge of the socket housing, and a notch is formed between the abutment plate and the inner side wall of the socket housing;

[0009] When the connectors are plugged in, the pressing part on the floating outer shell presses against the latch, thereby driving the plug body and the floating outer shell to be inserted into the socket shell. When inserted together, the guide column is inserted into the guide groove for docking guidance, and the extrusion groove presses against the latch to cause it to elastically deform, thereby causing the pressing part to be unhooked and enter a floating state. The pressing part and the floating outer shell continue to be plugged in so that the plug-in part is inserted into the slot with interference.

[0010] As a preferred embodiment of the above technical solution, the upper portion of the inner core is adapted to the inner cavity of the floating outer shell, and the lower portion of the inner core is adapted to the inner cavity of the socket shell.

[0011] As a preferred embodiment of the above technical solution, the top opening of the guide groove is processed into a trumpet shape.

[0012] As a preferred embodiment of the above technical solution, the fastener includes a fixed end, a connecting section and a fastening end that are integrally connected;

[0013] The longitudinal section of the buckle end is an inverted right-angled trapezoid, and the bottom end of the pressing piece is hook-shaped; when the floating outer shell and the plug body are inserted into the socket shell together, the pressing piece and the connecting section are flush and against the trapezoidal bottom surface of the buckle end.

[0014] As a preferred embodiment of the above technical solution, the front side of the buckle end is perpendicular to the longitudinal section and extends outwardly to form an extension portion, and the extension portion faces the extrusion groove.

[0015] As a preferred embodiment of the above technical solution, inner core protrusions are processed on both sides of the bottom of the inner core;

[0016] The abutment plate includes an integrally connected abutment plate protrusion, a connecting portion and a fixing portion, a notch between the connecting portion and the inner side wall of the socket housing, and the abutment plate protrusion facing the inner core protrusion to form a staggered overlapping structure.

[0017] The beneficial effects of the present invention are:

[0018] The optical backplane connector solution designed in the present invention can achieve precise blind plug-in docking through only three integrated components and a guide mechanism, reducing the tolerance impact of multi-part assembly and ensuring stable contact of the optical fiber end faces. The present invention has a simple structure and does not require additional tools. It can be plugged and unplugged by simply pressing with one hand, greatly improving the efficiency of assembly and disassembly, breaking through the technical limitations of traditional designs, and is suitable for backplane integration and on-site maintenance of high-speed optical communication systems.

[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0029] Example

[0030] like Figure 1 、 Figure 2 As shown, in the present invention, the xoz plane is the longitudinal section of the present invention, the xoy plane is the cross section of the present invention, and the yoz plane is the vertical section of the present invention.

[0031] A quick plug-in integrated optical fiber connector, comprising:

[0032] The floating outer shell 1 has a front surface and a side surface thereof integrally connected with a press-fitting piece 11 and an inserting piece 12;

[0033] The plug body 2 includes an inner core 22 , the front and bottom of the inner core 22 are integrally connected with a latch 21 and a guide post 23 ;

[0034] like Figure 3 As shown, the socket housing 3 has a guide groove 31 and an extrusion groove 33 respectively formed in the middle and inner wall edge of the socket housing 3. The inner edge of the socket housing 3 is integrally connected with a plate 32, and a notch is formed between the plate 32 and the inner side wall of the socket housing 3.

[0035] The fastener 21 includes a fixed end 211, a connecting section 212 and a fastening end 213 that are integrally connected;

[0036] The longitudinal section of the snap end 213 is an inverted right-angled trapezoid, and the bottom end of the pressing piece 11 is hook-shaped; when the floating outer shell 1 together with the plug body 2 is inserted into the socket shell 3, the pressing piece 11 and the connecting section 212 are flush and against the trapezoidal bottom surface of the snap end 213.

[0037] The front side of the buckle end 213 is perpendicular to the longitudinal section and extends outwardly to form an extension portion, and the extension portion faces the extrusion groove 33 .

[0038] The top opening of the guide groove 31 is processed into a trumpet shape.

[0039] When the connector of the present invention is plugged in, the floating outer shell 1 is first placed on the outer periphery of the plug body 2 from top to bottom, that is, Figures 1 to 2 In the state shown, the longitudinal sections of the pressing member 11 and the connecting section 212 are flush with each other and the hook portion at the bottom end of the pressing member 11 abuts against the trapezoidal bottom surface of the buckle end 213;

[0040] Then continue to push the floating outer shell 1 downward. Since the pressing piece 11 presses against the latch 21, the floating outer shell 1 can be pushed to drive the plug body 2 toward the socket shell 3 for insertion. In the initial stage of insertion, the guide post 23 is inserted from the trumpet-shaped opening at the top of the guide groove 31 to achieve accurate docking during blind insertion. Under the vertical guidance of the guide post 23 and the guide groove 31, the floating outer shell 1 and the plug body 2 continue to be inserted downward until they reach the socket shell 3. Figure 4 state, at which point its internal structure is as follows Figure 5 、 Figure 6 As shown, the inserting member 12 reaches above the slot, and the extended portion of the buckle end 213 is inclined against the upper corner of the extrusion slot 33;

[0041] At this time, the floating outer shell 1 and the plug body 2 continue to be inserted downward, and under the mutual resistance of the inclined surface of the extended portion of the buckle end 213 and the upper corner of the extrusion groove 33, the connecting section 212 moves downward a short distance and elastically deforms in the direction away from the pressing piece 11. At this time, the hook part at the bottom end of the pressing piece 11 breaks away from the trapezoidal lower bottom surface of the buckle end 213 and enters a floating state. Then, the floating outer shell 1 is pushed downward again, so that the bottom end of the pressing piece 11 passes over the buckle end 213, and the connecting section 212 rebounds upward. At this time, the pressing piece 11 is pushed downward again. Figure 7 、 Figure 8 In the state shown, the inclined surface of the hook at the bottom end of the press-fitting piece 11 abuts against the inclined surface of the clip end 213, and the press-fitting piece 11 is inserted into the notch with interference fit to achieve a tight installation. The optical backplane connector solution designed by the present invention achieves precise blind mating through only three integrated components and a guide mechanism, reducing the tolerance impact of multi-part assembly and ensuring stable contact between the optical fiber end faces. The present invention has a simple structure and does not require additional tools. It can be plugged and unplugged with a single hand press, greatly improving the efficiency of assembly and disassembly, breaking through the technical limitations of traditional designs, and is suitable for backplane integration and on-site maintenance of high-speed optical communication systems.

[0042] Inner core protrusions 221 are machined on both sides of the bottom of the inner core 22;

[0043] The support plate 32 includes an integrally connected support plate protrusion 321, a connecting portion 322 and a fixing portion 323. A notch is formed between the connecting portion 322 and the inner side wall of the socket housing 3, and the support plate protrusion 321 faces the inner core protrusion 221 to form a staggered overlapping structure.

[0044] In order to ensure the tightness of the interference fit between the notch and the press-fit piece 11, the present invention provides a plate protrusion 321 and an inner core protrusion 221; in the initial stage of inserting the floating outer shell 1 and the plug body 2 into the socket shell 3, the lower inclined surface of the inner core protrusion 221 first abuts against the upper inclined surface of the plate protrusion 321, and then in the process of continuing to move downward, the connecting portion 322 undergoes elastic deformation, and the inner core protrusion 221 passes over the plate protrusion 321 and reaches Figure 5 In the state shown, the lower inclined surface of the support plate protrusion 321 is against the upper inclined surface of the inner core protrusion 221; then the plug body 2 continues to move downward a short distance under the drive of the floating outer shell 1, the connecting section 212 is elastically deformed, and at the same time the inner core protrusion 221 continues to move downward a short distance along the outer side of the connecting portion 322; when the floating outer shell 1 is continued to be pushed downward to drive the plug-in part 12 to be inserted into the slot, the connecting section 212 rebounds upward to drive the inner core protrusion 221 to move upward until the upper inclined surface of the inner core protrusion 221 is again obliquely against the lower inclined surface of the support plate protrusion 321, thereby avoiding horizontal movement of the support plate 32, and thus ensuring the tightness of the interference fit between the slot and the press-fit part 11.

[0045] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
