Detailed Description of the Embodiment

[0045] The following further describes the present application in detail with reference to the attached Figure 1 - attached Figure 5 drawings.

[0046] The embodiment of the present application discloses a flip-chip applied patch digital tube.

[0047] Referring to Figure 1 , the flip-chip applied patch digital tube includes a housing 1 and a chip 11 welded inside the housing 1. A connection device 2 is provided on the housing 1, and the housings 1 of adjacent two digital tubes are connected together through the connection device 2.

[0048] Referring to Figure 1 and Figure 2, the connecting device 2 includes a connecting rod 21 and a sliding mechanism 22. Horizontal sliding grooves 12 and connecting grooves 13 are respectively formed on two opposite side walls of the housing 1. The connecting rod 21 is slidably mounted on the housing 1 and is located in the sliding groove 12. The sliding mechanism 22 is arranged on the housing 1 and is used to drive the connecting rod 21 to move. The connecting rod 21 partially extends out of the sliding groove 12 under the action of the sliding mechanism 22 and is inserted and matched with the connecting groove 13 on the side wall of the adjacent housing 1. An arc-shaped guiding surface 14 is formed on the end surface of the end of the connecting rod 21 inserted into the connecting groove 13.

[0049] Referring to Figure 2 and Figure 3 , the sliding mechanism 22 includes a sliding spring 23 and a limiting component 24. One end of the sliding spring 23 is fixedly connected to the inner bottom wall of the sliding groove 12, and the other end of the sliding spring 23 is fixedly connected to the end of the connecting rod 21. The connecting rod 21 partially extends out of the sliding groove 12 under the action of the sliding spring 23 and is inserted and matched with the connecting groove 13 on the side wall of the adjacent housing 1. The limiting component 24 is arranged on the housing 1, and the limiting component 24 is used to limit the position of the connecting rod 21 when the whole connecting rod 21 is located in the sliding groove 12.

[0050] Referring to Figure 2 and Figure 3 , the limiting component 24 includes a limiting rod 25, a limiting spring 26 and a pull rod 27. A limiting groove 15 is formed on the inner side wall of the sliding groove 12, and a limiting hole 16 communicating with the limiting groove 15 is formed on the side wall of the connecting rod 21. The limiting rod 25 is slidably mounted on the housing 1 and is located in the limiting groove 15. One end of the limiting spring 26 is fixedly connected to the inner bottom wall of the limiting groove 15, and the other end of the limiting spring 26 is fixedly connected to the limiting rod 25. The limiting rod 25 partially extends out of the limiting groove 15 under the action of the limiting spring 26 and is inserted and matched with the limiting hole 16. The pull rod 27 is slidably mounted on the housing 1. One end of the pull rod 27 is located in the limiting groove 15 and is connected to the limiting rod 25, and the other end of the pull rod 27 is located outside the housing 1.

[0051] Referring to Figure 2 and Figure 3 , when the digital tube is used alone, the whole connecting rod 21 is located in the sliding groove 12. At this time, the limiting rod 25 partially extends out of the limiting groove 15 under the action of the limiting spring 26 and is inserted and matched with the limiting hole 16 on the connecting rod 21. When the digital tubes need to be connected to each other, pull the pull rod 27. The movement of the pull rod 27 drives the limiting rod 25 to move by compressing the limiting spring 26. The whole limiting rod 25 moves into the limiting groove 15 and disengages from the limiting hole 16. At this time, the connecting rod 21 partially extends out of the sliding groove 12 under the action of the sliding spring 23 and is inserted and matched with the connecting groove 13 on the side wall of the adjacent housing 1. Thus, the connection work between the housings 1 of two adjacent digital tubes is completed.

[0052] Referring to Figure 3 andFigure 4 On the inner sidewall of the connecting groove 13 on the housing 1, a fixing groove is provided. A moving groove 18 communicating with the fixing groove is radially provided on the sidewall of the connecting rod 21, and a fixing block 28 is slidably mounted on the moving groove 18. A moving component 3 is arranged on the connecting rod 21. When the connecting rod 21 is inserted into the connecting groove 13, the fixing block 28 is clamped with the fixing groove under the action of the moving component 3.

[0053] Refer to Figure 3 and Figure 4 As shown in FIGS. and, the moving component 3 includes a moving spring 31, a moving plate 32 and a pressing plate 33. A moving cavity 34 communicating with the moving groove 18 is provided inside the connecting rod 21. A second through hole 36 communicating with the moving cavity 34 is provided on the sidewall of the connecting rod 21. The second through hole 36 and the moving groove 18 are respectively located at both ends of the moving plate 32. The moving plate 32 is slidably mounted in the moving cavity 34 and is connected to the fixing block 28 at one end. One end of the pressing plate 33 is fixedly connected to the moving plate 32, and the other end of the pressing plate 33 extends out of the second through hole 36. A first through hole communicating with the second through hole 36 is provided on the housing 1. The pressing plate 33 is located in the first through hole.

[0054] Refer to Figure 2 and Figure 4 As shown in FIGS. and, when the connecting rod 21 is inserted into the connecting groove 13, the moving spring 31 drives the fixing block 28 to partially penetrate out of the moving groove 18 and be clamped with the fixing groove 17, thereby limiting the connecting rod 21 in the connecting groove 13, reducing the probability of the connecting rod 21 slipping out of the connecting groove 13, and ensuring the connection strength between two adjacent housings 1. When it is necessary to separate the connecting rod 21 from the connecting groove 13, the pressing plate 33 is pressed downward. The pressing plate 33 moves downward to compress the moving spring 31 and drives the moving plate 32 to move downward. The moving plate 32 moves downward to drive the fixing block 28 to move into the moving groove 18, so that the fixing block 28 can be separated from the fixing groove 17, facilitating the removal of the connecting rod 21 from the connecting groove 13.

[0055] Refer to Figure 5 As shown in FIG., an installation component 4 is provided on the housing 1. A cover plate 37 is detachably arranged on the housing 1 through the installation component 4. The cover plate 37 covers the first through hole. The installation component 4 includes an installation ring 41 and an installation post 42. There are four installation rings 41, and the four installation rings 41 are respectively fixedly connected to the four corners on the surface of the housing 1. The four installation posts 42 are respectively fixedly connected to the four corners on the surface of the cover plate 37. Moving the cover plate 37 so that the installation posts 42 are inserted into the installation rings 41 can complete the connection work between the cover plate 37 and the housing 1. The cover plate 37 covers the first through hole 35 to make the surface of the housing 1 smooth and flat.

[0056] The working principle of the embodiment of the present application is as follows:

[0057] Move two adjacent housings 1 so that the sliding groove 12 on one housing 1 is aligned with the connecting groove 13 on the other housing 1. Pull the pull rod 27 so that the limiting rod 25 is completely moved into the limiting groove 15 and disengaged from the limiting hole 16. Then, under the action of the sliding spring 23, the connecting rod 21 partially penetrates outside the sliding groove 12 and is inserted and matched with the connecting groove 13. In this way, two adjacent housings of the digital tubes can be connected together, which is convenient, fast and has high work efficiency.
