Detailed Embodiment

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0018] Referring to Figures 1 - 8 , an optoelectronic conversion connector includes a housing 1 and two plug-ins 2. A square groove 31 is opened in the housing 1. A connector 3 is fixedly connected to the inner wall of the square groove 31. A square block 4 is fixedly connected to the side wall of the plug-in 2 close to the housing 1. Two plugs 5 connected to the connector 3 are installed on the side wall of the square block 4 (as Figure 2 shown).

[0019] An installation mechanism, the installation mechanism includes four through grooves 6 opened in the inner wall of the square groove 31 close to the end (as Figure 4 and Figure 7 shown). A clamping block 7 is slidably connected to the inner wall of each of the four through grooves 6. Four first clamping grooves 8 corresponding to the four clamping blocks 7 one by one are opened in the side wall of the square block 4 (as Figure 6 shown). The inner wall of the through groove 6 far from the square groove 31 is rotatably connected to a turntable 10 through a first rod 9. The side wall of the turntable 10 far from the first rod 9 is rotatably connected to the side wall of the clamping block 7 close to it through a connecting rod 11.

[0020] The housing 1 is provided with a rotating mechanism for driving the four first rods 9 to rotate. The rotating mechanism includes four arc-shaped tooth plates 13. Two rings 12 that can rotate by themselves are slidably connected to the side wall of the housing 1 (as Figure 5 shown). A fixed connection is made between the side walls of the two rings 12 close to each other and the side walls of the four arc-shaped tooth plates 13. A fixed connection is made between the side walls of two adjacent arc-shaped tooth plates 13. A gear 14 is fixedly connected to the side wall of each of the four first rods 9. The arc-shaped tooth plate 13 meshes with the side wall of its corresponding gear 14 during rotation.

[0021] As Figure 4 shown, the arc-shaped tooth plate 13 is composed of a toothed part surface and a toothless part surface. In the initial position, the gear 14 corresponds to the toothless part surface of the arc-shaped tooth plate 13.

[0022] When it is necessary to install the housing 1 and the plug-in 2, first rotate the four arc-shaped tooth plates 13 clockwise (as Figure 4As shown in the figure, when the four arc-shaped toothed plates 13 rotate and engage with the four gears 14, the four gears 14 are driven to rotate clockwise. At this time, the first rod 9 drives all the clamping blocks 7 to move into the through groove 6 through the turntable 10 and the connecting rod 11. Subsequently, the square block 4 on the plug-in member 2 is inserted into the square groove 31. When the side walls of the housing 1 and the plug-in member 2 are in contact, at this time, the four clamping blocks 7 are facing the four first clamping grooves 8. Subsequently, the four arc-shaped toothed plates 13 are rotated counterclockwise (as Figure 4 shown), to their original positions. At this time, the four gears 14 are driven to rotate counterclockwise to their original positions, thereby driving the four clamping blocks 7 to move closer to each other to their original positions, and inserting the four clamping blocks 7 into the four first clamping grooves 8, completing the installation between the housing 1 and the plug-in member 2. The operation is simple and convenient for disassembly, avoiding the trouble in the assembly and disassembly process of the plug contact and the optoelectronic conversion connector by connecting them with multiple screws in the prior art, resulting in low assembly efficiency.

[0023] A torsion spring 30 is sleeved on the side wall of the first rod 9. One end of the torsion spring 30 is fixedly connected to the inner wall of the through groove 6, and the other end of the torsion spring 30 is fixedly connected to the side wall of the gear 14 (as Figure 5 shown).

[0024] When the arc-shaped toothed plate 13 rotates clockwise to drive the gear 14 to rotate clockwise (as Figure 4 shown), at this time, elastic potential energy will be stored on the torsion spring 30. And when the arc-shaped toothed plate 13 rotates counterclockwise to drive the gear 14 to rotate counterclockwise (as Figure 4 shown), at this time, the elastic potential energy on the torsion spring 30 will be released to the initial position. At this time, the clamping block 7 is located at the initial position, so that during the later use process, the torsion spring 30 will limit the rotation of the gear 14, making the clamping block 7 stably inserted into the first clamping groove 8.

[0025] A clamping mechanism for clamping the clamping block 7 is provided in the housing 1. The clamping mechanism includes an L-shaped groove 15 opened on the inner side wall of the through groove 6. A clamping plate 16 is slidably connected to the inner wall of the L-shaped groove 15 close to the clamping block 7 (as Figure 4 shown). A second clamping groove 17 cooperating with the clamping plate 16 is opened on the side wall of the clamping block 7 (as Figure 6 shown). A sliding plate 18 is slidably connected to the inner wall of the L-shaped groove 15 far from the clamping block 7. A first plate 19 is fixedly connected to the side wall of the clamping plate 16 far from the clamping block 7. A second plate 20 is fixedly connected to the side wall of the sliding plate 18 close to the clamping plate 16. A third plate 21 is rotatably connected between the side walls of the first plate 19 and the second plate 20. The side wall of the sliding plate 18 far from the second plate 20 is elastically connected to the inner wall of the L-shaped groove 15 through a plurality of first springs 22.

[0026] A sliding rod 23 is fixedly connected to the side wall of the sliding plate 18 far from the second plate 20. One end of the sliding rod 23 far from the sliding plate 18 penetrates through the side wall of the housing 1 and is fixedly connected to an extrusion head 24. An arc-shaped clamping groove 25 cooperating with the extrusion head 24 is opened on the inner side wall of the arc-shaped toothed plate 13.

[0027] As Figure 4 shown, when the arc-shaped tooth plate 13 rotates clockwise, first, the extrusion head 24 is extruded towards the direction close to the L-shaped groove 15 through the arc-shaped card slot 25. At this time, the arc-shaped tooth plate 13 is not engaged with the gear 14. The extrusion head 24 extrudes the slide plate 18 through the slide rod 23, so that the slide plate 18 drives the clamping plate 16 to move away from the clamping block 7 through the first plate 19, the second plate 20 and the third plate 21, so that the clamping plate 16 moves out of the second card slot 17. Subsequently, the arc-shaped tooth plate 13 will be engaged with the gear 14 to drive the clamping block 7 to move into the through groove 6; When the clamping block 7 is inserted into the first card slot 8, the arc-shaped tooth plate 13 will continue to rotate counterclockwise (as Figure 4 shown). When the extrusion head 24 corresponds to the arc-shaped card slot 25, at this time, under the action of a plurality of first springs 22, the slide plate 18 drives the side wall of the extrusion head 24 to fit with the inner wall of the arc-shaped card slot 25. At this time, the slide plate 18 slides to its original position. At this time, the slide plate 18 drives the clamping plate 16 to move towards the direction close to the clamping block 7 through the first plate 19, the second plate 20 and the third plate 21, so that the clamping plate 16 is inserted into the second card slot 17, and the position of the clamping block 7 is limited again, increasing the stability after the housing 1 and the plug-in 2 are installed.

[0028] Elastic sealing rings 26 are fixedly connected to both ends of the housing 1. An annular groove 27 (as Figure 8 shown) matching with the elastic sealing ring 26 is provided on the side wall of the plug-in 2, and hydraulic oil is provided in the elastic sealing ring 26.

[0029] A fuel storage bag 28 is fixedly connected to the side wall of the slide plate 18 far away from the second plate 20. The side wall of the fuel storage bag 28 far away from the slide plate 18 is fixedly connected to the inner wall of the L-shaped groove 15 (as Figure 4 shown). The inner wall of the fuel storage bag 28 is communicated with the inner wall of the elastic sealing ring 26 through a connecting pipe 29 (as Figure 4 , Figure 6 and Figure 7 shown).

[0030] When the extrusion head 24 extrudes the slide plate 18 through the slide rod 23, at this time, the fuel storage bag 28 elongates. At this time, the fuel storage bag 28 sucks hydraulic oil from the elastic sealing ring 26 through the connecting pipe 29, so that the elastic sealing ring 26 can easily enter the annular groove 27. When the slide plate 18 slides to its original position, at this time, the fuel storage bag 28 is extruded, so that the hydraulic oil in the fuel storage bag 28 enters the elastic sealing ring 26 through the connecting pipe 29, so that the elastic sealing ring 26 expands and fits tightly with the inner wall of the annular groove 27, increasing the sealing performance between the housing 1 and the plug-in 2, and avoiding the problem that the connection between the plug contact and the photoelectric conversion connector in the prior art is not tight enough, so that dust and moisture are likely to enter during subsequent use, thus affecting the operating stability of the photoelectric conversion connector.

[0031] When installing the housing 1 and the plug-in 2, first rotate the four arc-shaped toothed plates 13 clockwise (as shown in Figure 4 ), the arc-shaped card slot 25 will squeeze the extrusion head 24 towards the direction close to the L-shaped slot 15. At this time, the arc-shaped toothed plate 13 is not engaged with the gear 14. The extrusion head 24 squeezes the slide plate 18 through the slide rod 23, so that the slide plate 18 drives the clamping plate 16 to move away from the clamping block 7 through the first plate 19, the second plate 20 and the third plate 21, so that the clamping plate 16 moves out of the second card slot 17. Subsequently, the arc-shaped toothed plate 13 will be engaged with the gear 14, and the gear 14 rotates clockwise. At this time, the first rod 9 drives the clamping block 7 to move all into the through slot 6 through the turntable 10 and the connecting rod 11. Subsequently, insert the square block 4 on the plug-in 2 into the square slot 31. When the side walls of the housing 1 and the plug-in 2 are attached, at this time, the four clamping blocks 7 are facing the four first card slots 8, and the two plugs 5 on the square block 4 are connected to the connector 3; Subsequently, rotate the arc-shaped toothed plate 13 counterclockwise (as shown in Figure 4 ) to the original position, drive the gear 14 to rotate counterclockwise to the original position. Furthermore, the first rod 9 drives the clamping block 7 to move out of the through slot 6 through the turntable 10 and the connecting rod 11, drives the four clamping blocks 7 to move closer to each other to the original position, and inserts the four clamping blocks 7 into the four first card slots 8 to complete the installation between the housing 1 and the plug-in 2. The operation is simple and convenient for disassembly; When the arc-shaped toothed plate 13 continues to rotate counterclockwise so that the extrusion head 24 corresponds to the arc-shaped card slot 25, at this time, under the action of a plurality of first springs 22, the slide plate 18 drives the side wall of the extrusion head 24 to fit with the inner wall of the arc-shaped card slot 25. At this time, the slide plate 18 slides to the original position. At this time, the slide plate 18 drives the clamping plate 16 to move towards the direction close to the clamping block 7 through the first plate 19, the second plate 20 and the third plate 21, so that the clamping plate 16 is inserted into the second card slot 17 to limit the position of the clamping block 7 again and increase the stability after the installation of the housing 1 and the plug-in 2; When the extrusion head 24 squeezes the slide plate 18 through the slide rod 23, at this time, the oil storage bladder 28 elongates. At this time, the oil storage bladder 28 sucks hydraulic oil from the elastic sealing ring 26 through the connecting pipe 29. When the housing 1 and the plug-in 2 are attached before, at this time, the elastic sealing ring 26 can easily enter the annular groove 27. When the slide plate 18 slides to the original position, at this time, the oil storage bladder 28 is squeezed, so that the hydraulic oil in the oil storage bladder 28 enters the elastic sealing ring 26 through the connecting pipe 29, so that the elastic sealing ring 26 expands and fits tightly with the inner wall of the annular groove 27, increasing the sealing performance between the housing 1 and the plug-in 2.
