Description

TECHNICAL FIELD

[0001] The present application relates to a fiber connector, and particularly to a co-packaged photon fiber connector. BACKGROUND

[0002] Co-packaged photon (CPO) is a technology that co-packages optical components and electronic components on the same substrate, aiming to improve data transmission efficiency, reduce power consumption and cost, and reduce system size. CPO reduces the loss of optical signals in traditional packaging by integrating optical components more closely into electronic wafers, while improving signal transmission speed and bandwidth. By shortening the optical signal transmission path, CPO can reduce the energy required for signal transmission and reduce overall power consumption. SUMMARY

[0003] The present application provides a co-packaged photon fiber connector, which can quickly combine or separate the fiber assembly and the photon integrated circuit through the disassembly of the fixing mechanism, and does not damage the fiber assembly.

[0004] The co-packaged photon fiber connector of the present application is arranged on the photon integrated circuit to receive the fiber assembly and optically couple the fiber assembly to the photon integrated circuit. The co-packaged photon fiber connector includes a housing, an intermediate piece, and a spring. The housing is mounted on the photon integrated circuit and has a slot. The intermediate piece is adapted to be inserted into or pulled out of the slot, and the intermediate piece has a shaft portion. A portion of the spring is pivoted to the shaft portion to pivot relative to the intermediate piece. In the fixed state, the fiber assembly is inserted into the slot, the intermediate piece is inserted into the slot and covers the fiber assembly, and another portion of the spring is retained in the housing to assemble the intermediate piece and the housing together. The spring presses the fiber assembly through the intermediate piece to fix the fiber assembly in the slot of the housing.

[0005] Based on the above, the co-packaged photon fiber connector is assembled to the intermediate piece and can pivot relative to the housing. After the fiber assembly is inserted into the slot and the intermediate piece is inserted into the slot to cover the fiber assembly, the spring can be pivoted and retained in the housing, that is, the housing and the intermediate piece are retained together by the spring, and the spring force can be pressed on the fiber assembly through the intermediate piece to fix the fiber assembly in the slot of the housing. In addition to the quick disassembly of the fiber assembly and the photon integrated circuit through the cooperation of the spring, the housing and the intermediate piece, the spring pivoted to the intermediate piece can be hooked to the housing to provide effective binding force after the intermediate piece is inserted into the slot. More importantly, the spring is retained and abuts against the housing and the intermediate piece, and does not directly contact the fiber assembly in structure, so that the purpose of protecting the fiber assembly by the intermediate piece can be effectively achieved, thereby providing a stable assembly mechanism for the fiber assembly and the photon integrated circuit and improving the service life of the fiber assembly.

The co-packaged photonic fiber optic connector 100 includes a housing 110, an intermediary 120, and a spring 130. After the intermediary 120 and the fiber optic assembly 200 are assembled into the housing 110, the spring 130 holds the housing 110 in place, thereby combining the housing 110 and the intermediary 120 together and pressing the fiber optic assembly 200 therebetween.

Unlike electronic integrated circuits that transmit electrons, integrated optical elements primarily transmit optical signals in the visible or infrared bands, and the connections between components in the circuit are achieved through optical waveguides. Through these miniaturized and highly stable integrated optical elements, optoelectronic communication systems can play an increasingly important role and function.

A portion of the spring 130 is pivotally connected to the shaft portion 121 to pivot relative to the intermediary 120. In the fixed state, the fiber assembly 200 is inserted into the slot 112, the intermediary 120 is inserted into the slot 112 and covers the fiber assembly 200, and another portion of the spring 130 is buckled to the buckling portion 118 of the housing 110 to assemble the intermediary 120 and the housing 110 together. The spring 130 presses the fiber assembly 200 through the intermediary 120, so that the fiber assembly 200 is fixed in the slot 112 of the housing 110. In this embodiment, the housing 110 is located on the X-Y plane, and the intermediary 120 and the fiber assembly 200 move towards the positive Y-axis direction to be inserted into the slot 112, and move towards the negative Y-axis direction to be detached from the slot 112.

[0020] In detail, the housing 110 of this embodiment further has a block 111 and a bottom plate 117, the block 111 has an inner stop surface S1, and the bottom plate 117 and the two side walls 113 are extended from the block 111 in the same direction (towards the negative Y-axis direction) and form the slot 112 with the inner stop surface S1.

[0021] FIG. 3 and FIG. 4A respectively show part of the components of the co-packaged photonic fiber connector from different perspectives. Please refer to FIG. 1A , FIG. 2 and FIG. 3 , the housing 110 has the two side walls 113 and the inner stop surface S1 forming the slot 112, the two side walls 113 are opposite to each other, and the inner stop surface S1 is adjacent between the two side walls 113. In the fixed state, the inner side surface S3 of the intermediary 120 abuts against the inner stop surface S1. Further, the slot 112 of this embodiment has a first end E1 and a second end E2 opposite to each other, and the fiber assembly 200 and the intermediary 120 are adapted to move from the second end E2 to the first end E1 to be inserted into the slot 112, or move from the first end E1 to the second end E2 to be detached from the slot 112. In the fixed state, the shaft portion 121 of the intermediary 120 is located at the second end E2.

[0022] FIG. 4B show the intermediary from another perspective. Please refer to FIG. 2 , FIG. 4A and FIG. 4B , wherein FIG. 4Abe considered as the state after the intermediary 120 and the fiber assembly 200 have been inserted into the slot 112 (here, the shell 110 is omitted), and FIG. 4B is as FIG. 4A further omitted the fiber assembly 200. In the present embodiment, the intermediary 120 is in an inverted U-shaped structure, and has two abutting ribs 122 and a channel 124 between the two abutting ribs 122. Correspondingly, the fiber assembly 200 includes a fiber module 220 and a base 210, and the fiber module 220 is arranged on the base 210. As shown in FIG. 4A , in the fixed state, the fiber assembly 200 is accommodated in the channel 124, and the abutting block 123 of the intermediary 120 abuts against the base 210. Corresponding to FIG. 1A or FIG. 2 , it can be seen that when the intermediary 120 is buckled to the buckling part 118 of the shell 110 by the elastic piece 130, it is equivalent to providing a force of the intermediary 120 in the positive Y-axis direction, so that the abutting block 123 is tightly abutted against the base 210, and the inner side surface S3 of the intermediary 120 is tightly abutted against the inner stop surface S1 of the shell 110, and the base 210 of the fiber assembly 200 is successfully clamped between the abutting block 123 and the inner stop surface S1. Here, the abutting block 123 can be considered as extending from the structure of the abutting rib 122 and being on the same side of the shaft part 121 of the intermediary 120 and being arranged in an upper and lower configuration along the Z-axis, as shown in FIG. 1A .

[0023] Further, please refer to FIG. 2 , FIG. 3 and FIG. 4A , the shell 110 also has a first guide column 114 extending from the inner stop surface S1 along the side wall 113 in the slot 112, and at least one of the intermediary 120 and the fiber assembly 200 has a first guide groove for adapting to the first guide column 114. In the present embodiment, the V-shaped groove 125 at the abutting rib 122 of the intermediary 120 (as shown in FIG. 4B ) is matched with the V-shaped groove 211 on the wing part of the base 210 of the fiber assembly 200 (as shown in FIG. 2 ), and together form the first guide groove CH of the present case. However, the present case is not limited thereto, and in other embodiments not shown, the first guide column 114 can be appropriately adjusted so that one of the intermediary 120 or the base 210 of the fiber assembly 200 has the aforementioned first guide groove. In other words, any one that can make the fiber assembly 200 and the intermediary 120 smoothly move into the slot 112 of the shell 110 and achieve the desired guiding and positioning effect can be applied to the present case.

[0024] Please refer to FIG. 2, the elastic piece 130 of the present embodiment is T-shaped and has a horizontal segment T2 and a straight segment T1, the straight segment T1 meets the center of the horizontal segment T2, the end of the straight segment T1 away from the horizontal segment T2 has a pivot portion 131, and the pivot portion 131 is pivotally wrapped around the shaft portion 121. The opposite ends of the horizontal segment T2 each have a clamping hook 132, and in the fixed state, the clamping hook 132 clamps the external structure (i.e., the clamping portion 118) of the housing 110 facing away from the slot 112. The elastic piece 130 of the present embodiment also includes a pull handle 133 extending from the center of the horizontal segment T2 and relative to the straight segment T1. The pull handle 133 is beneficial for the user to hold to operate the elastic piece 130 to pivot relative to the intermediate piece 120 to facilitate clamping to or releasing from the clamping portion 118.

[0025] FIG. 5A With FIG. 5B are cross-sectional views of the co-packaged photonic fiber connector in different states. Please refer to FIG. 1B , FIG. 5A and FIG. 5B , the housing 110 of the present embodiment also has a hollow portion 115 facing the photonic integrated circuit 300 and communicating with the slot 112. The fiber module 220 of the present embodiment includes a fiber (array) 221 and an optical element (array) 222, and the photonic integrated circuit 300 includes an optical waveguide 310. In the fixed state, the base 210 is located in the slot 112 and abuts against the inner stop surface S1, the fiber module 220 extends from the slot 112 to the hollow portion 115 to correspond to the photonic integrated circuit 300, and as FIG. 3 shown, the fiber assembly 200 and the photonic integrated circuit 300 complete light coupling, that is, the optical signal represented by the dashed arrow can be transmitted from the optical waveguide 310, the optical element 222 to the fiber 221.

[0026] To successfully reach the aforementioned fixed state, the elastic piece 130 of the present embodiment is in a bent original (unforced) state at the straight section T1 thereof, so that in the fixed state, the straight section T1 will be deformed and accumulate elastic force due to the interference with the top surface S2 of the intermediate piece 120, to provide the first force F1 to the top surface S2 to press the intermediate piece 120 against the insertion slot 112, and also press the optical fiber assembly 200 covered by the intermediate piece 120, so that the optical fiber assembly 200 is substantially fixed between the intermediate piece 120 and the slot bottom (i.e., the aforementioned bottom plate 117) of the insertion slot 112. Furthermore, in the fixed state, the clasp 132 of the elastic piece 130 also provides the second force F2 to the clamping portion 118 of the housing 110, which is equivalent to the pivot portion 131 of the elastic piece 130 providing a counterforce to the intermediate piece 120, in cooperation with the second force F2 to abut the intermediate piece 120 and the housing 110 together along the Y axis, and further press the optical fiber assembly 200 between the intermediate piece 120 and the housing 110. Accordingly, through the aforementioned force provided by the elastic piece 130 to the housing 110 and the intermediate piece 120, the optical fiber assembly 200 can be effectively fixed in the insertion slot 112. In short, the elastic piece 130 can be regarded as a fastener structure that combines the intermediate piece 120 and the housing 110 together.

[0027] As shown by the dashed line in the partial enlarged view of FIG. 5B , the straight section T1 of the elastic piece 130 will interfere with the top surface S2 of the intermediate piece 120, to drive the elastic piece 130 to deform and accumulate elastic force and form the first force F1.

[0028] FIG. 5C is FIG. 1A a partial view of the co-packaged photonic fiber connector of FIG. 5B and FIG. 5C It should also be mentioned that the intermediate piece 120 of the present embodiment also has a stop protrusion 122a extending from the abutting rib 122 away from the V-shaped groove 125 and protruding outside the intermediate piece 120, and the V-shaped groove 125 of the first guide groove CH is located between the channel 124 and the stop protrusion 122a, and the side wall 113 of the housing 110 has a terminal notch 116 at the second end E2 of the insertion slot 112, so that in the fixed state, the intermediate piece 120 is inserted into the insertion slot 112, the stop protrusion 122a fills the terminal notch 116, and the intermediate piece 120 is limited in the insertion slot 112, to avoid the intermediate piece 120 from being driven out of the insertion slot 112 by the elastic force of the elastic piece 130. As shown in FIG. 5B , in addition to providing the force along the Y axis to the housing 110, the clasp 132 will also substantially generate a third force F3 to the housing 110 due to the slope of the clamping portion 118. In this way, the second force F2 and the third force F3 will generate a moment through the shaft portion 121, to drive the intermediate piece 120 to overturn along the dashed arrow shown in FIG. 5B and be pulled out of the insertion slot 112. Therefore, the present embodiment can effectively fix the optical fiber assembly 200 in the insertion slot 112 throughFIG. 5C The stopper bump 122a interferes with the side wall 113 at the end notch 116 to prevent the aforementioned intermediate member 120 from being pulled out of the slot 112 by the spring 130.

[0029] FIG. 6 is a schematic view of a co-packaged photonic fiber connector according to another embodiment of the present application. FIG. 7 is FIG. 6 is an exploded view of the co-packaged photonic fiber connector of FIG. 6 and FIG. 7 It should be noted that the structures or components of the present embodiment that are identical to those of the aforementioned embodiments are not described again.

[0030] Different from the aforementioned embodiments, the housing 410 of the present embodiment is composed of a carrier P1 and a spacer P2, wherein the spacer P2 is assembled to the carrier P1, the spacer P2 has the first guide post 114 and the inner stop surface S1, and the carrier P1 has the slot 112 and the two side walls 113. The slot 112 has the first end E3 and the second end E4 opposite to each other, and the spacer P2, the fiber assembly 200 and the intermediate member 420 are inserted into the slot 112 from the second end E2 to the first end E1.

[0031] Further, the carrier P1 has a first arc-shaped rail 411A at the side wall 113, and the spacer P2 has a second arc-shaped rail 411B, the spacer P2 is assembled into the carrier P1 by fitting the second arc-shaped rail 411B to the first arc-shaped rail 411A, and is stopped at the end stop portion 412 of the first arc-shaped rail 411A. In the present embodiment, the first arc-shaped rail 411A has a pair of arc-shaped inner walls AR1 extending from the end stop portion 412 along the side wall 113, and the second arc-shaped rail 411B has a pair of arc-shaped outer walls AR2 fitted to the arc-shaped inner walls AR1 so that the second arc-shaped rail 411B can be substantially inserted into the space between the arc-shaped inner walls AR1. In addition, the second guide groove 419 exists between the arc-shaped outer walls AR2, and the intermediate member 420 further has a second guide post 421 protruding from the inner side surface S3 and fitted to the second guide groove 419, the intermediate member 420 is guided and positioned by the second guide post 421 and the second guide groove 419 fitting to each other during the insertion of the intermediate member 420 into the slot 112 and the spacer P2.

[0032] Different from the aforementioned FIG. 1A to FIG. 5BCompared with the shown embodiment, the present embodiment is provided according to the assembly requirement, wherein the present embodiment further divides the shell 410 into the carrier P1 and the spacer P2, so as to allow the operator to first assemble the spacer P2, the intermediate piece 420 and the fiber assembly 200, and then insert the three combined into the carrier P1 with the slot 112. It is known that the overall package photon fiber connector 400 of the present case has an appearance size (length, width, height) of about 18mm, 18mm, 6.5mm, which is not easy for the operator to operate and causes the work efficiency to be affected, so that the structure of the shell 410 is reset through the present embodiment, so as to greatly improve the assembly efficiency.

[0033] In summary, in the above-mentioned embodiments of the present application, the overall package photon fiber connector is assembled to the shell by the spring piece and can be pivoted relative to the shell. After the fiber assembly is inserted into the slot and the intermediate piece is inserted into the slot to cover the fiber assembly, one end of the spring piece is buckled and pivoted to the shaft portion of the intermediate piece, and the other end of the spring piece is buckled to the external structure of the shell opposite to the slot. In this way, the spring piece can buckle and combine the intermediate piece and the shell together, and further fix the fiber assembly in the slot and press it between the intermediate piece and the shell.

[0034] In one embodiment, the shell is of an integral structure, that is, the block and the side wall belonging to the same structure are made by a single process to have better mechanism accuracy and be beneficial to carrying and fixing the fiber assembly. In one embodiment, the shell is assembled by a carrier and a spacer separated from each other, wherein the carrier has the slot, and the spacer has the inner stop surface for abutting the intermediate piece. In this way, the fiber assembly is first assembled with the intermediate piece and the spacer, and then inserted into the slot of the shell, so as to change the assembly sequence by resetting the structure of the shell to improve the convenience and efficiency of the assembly process.

[0035] Based on the above, in addition to the fiber assembly and the photon integrated circuit being quickly disassembled by the cooperation of the spring piece, the shell and the intermediate piece, the spring piece pivoted on the intermediate piece can hook the shell after the intermediate piece is inserted into the slot to provide effective binding force. More importantly, the buckling and abutting objects of the spring piece are the shell and the intermediate piece, and there is no direct structural contact with the fiber assembly, so that the purpose of protecting the fiber assembly by the intermediate piece can be effectively achieved, and the stable assembly mechanism of the fiber assembly and the photon integrated circuit and the service life of the fiber assembly are improved.
