Description

Technical Field

[0001] This utility model relates to the field of industrial control computer technology, specifically to a data interface protection device for industrial control computers. Background Technology

[0002] With the continuous advancement of social informatization, the reliance of various industries on industrial control computers (ICPCs) for critical tasks is increasing. Under existing traditional technology, ICPCs typically place their audio and video interfaces externally for connection to external devices such as displays. This design requires extending the display cable to the outside of the ICPC to connect to the audio and video interface. However, this connection method exposes the connection point between the cable and the interface directly to the outside, making it highly susceptible to physical damage in real-world environments, thus affecting the ICPC's operational stability and reliability. To address these issues, this invention proposes a data interface protection device for ICPCs. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example: Please refer to Figures 1 to 6 According to an embodiment of the present invention, a data interface protection device for an industrial control computer is provided to protect the connecting cable 20 connected to the data interface 11 of the industrial control computer 10. The data interface 11 protection device includes a connecting base 30 and a U-shaped shielding buckle 40. The connecting base 30 is connected to the industrial control computer 10 and has a through-hole 31 corresponding to the position of the data interface 11. The connector 21 of the connecting cable 20 is adapted to move through the through-hole 31. The first end of the shielding buckle 40 is rotatably connected to the connecting base 30 through a rotating shaft 41, and the second end of the shielding buckle 40 is provided with an avoidance slot 42 and is fixed to the connecting base 30 through a snap-fit ​​structure 50.

[0028] The data interface protection device for industrial control computers using the above-described structure requires the following steps when connecting the cable 20 to the data interface 11 of the industrial computer 10: First, the shielding buckle 40 must be flipped upwards to open, ensuring that the socket 31 on the connector 30 is fully exposed. Then, the connector 21 of the cable 20 is passed through the socket 31 and plugged into the data interface 11 of the industrial computer 10. After the connector 21 is inserted, the shielding buckle 40 is fastened to the outside of the connector 21 of the cable 20, allowing the cable 20 to extend through the clearance notch of the shielding buckle 40. In this way, the shielding buckle 40 provides protection for the connector 21 of the cable 20, preventing it from suffering physical damage, thereby improving the operational stability and reliability of the industrial control computer.

[0029] In this exemplary embodiment, the working unit 10 has a plurality of data interfaces 11 arranged side by side, and the connector 30 is slidably connected to the working unit 10 via a slide rail 60 along the arrangement direction of the plurality of data interfaces 11. The connector 30 can move along the slide rail 60 to above any data interface 11 so that the shielding buckle 40 can perform protective measures on the connection line 20 at any data interface 11.

[0030] In this exemplary embodiment, a locking structure 70 is provided between the slide rail 60 and the connecting seat 30. The locking structure 70 can selectively lock the connecting seat 30 onto the slide rail 60 to restrict or allow the connecting seat 30 to slide along the slide rail 60. By providing the locking structure 70, when it is decided to implement protective measures for the connecting line 20 of a specific data interface 11, the connecting seat 30 can be moved above the data interface 11, and the position of the connecting seat 30 can be fixed by the locking structure 70 to prevent it from shifting when subjected to physical impact, thereby enhancing the protective effectiveness.

[0031] In this exemplary embodiment, the locking structure 70 includes a lock head 71 elastically disposed on the connecting seat 30 and a plurality of lock holes 72 disposed on the slide rail 60 along the length direction of the slide rail 60. A pusher 73 is provided at the first end of the blocking buckle 40. When the blocking buckle 40 rotates, the pusher 73 can push the lock head 71 to move, causing the lock head 71 to insert into or move out of the lock hole 72. With this configuration, when the blocking buckle 40 is activated, the pusher 73 will not contact the lock head 71, and the lock head 71 will not be inserted into the lock hole 72, allowing the connecting seat 30 to slide freely on the slide rail 60. After sliding the connecting seat 30 to the desired position, the connector 21 of the connecting cable 20 is inserted into the corresponding data interface 11. Then, the blocking buckle 40 is rotated to close it. At this time, the blocking buckle 40 is not only fixed, but its pusher 73 also pushes the lock head 71 into the corresponding lock hole 72, thereby locking the position of the connecting seat 30 on the slide rail 60. Therefore, by adopting the above design, the locking of the cover buckle 40 and the locking of the connector 30 can be combined, which simplifies the operation process.

[0032] In this exemplary embodiment, the connector 30 is provided with a mounting groove 300, the lock head 71 is disposed in the mounting groove 300, the mounting groove 300 has a socket 301 formed on the connector 30, the pusher 73 extends into the mounting groove 300 from the socket 301, the lock head 71 is elastically disposed in the mounting groove 300 by a spring 74, and a boss 302 is provided in the mounting groove 300 to limit the range of movement of the lock head 71.

[0033] In this exemplary embodiment, the buckle structure 50 includes an elastic deformation portion 51 disposed at the second end of the blocking buckle 40 and a locking hole 52 disposed on the connecting seat 30. The blocking buckle 40 and the elastic deformation portion 51 are integral structures. Specifically, the blocking buckle 40 and the elastic deformation portion 51 are made of spring steel 74. After elastic deformation, the elastic deformation portion 51 is adapted to be inserted into the locking hole 52. The elastic deformation portion 51 includes a bending portion 510, a force-applying portion 511 and a locking portion 512. The bending portion 510 is U-shaped. The first end of the bending portion 510 is fixedly connected to the blocking buckle 40, and the second end of the bending portion 510 is fixedly connected to the force-applying portion 511. The locking portion 512 protrudes out of the outside of the bending portion 510. The locking hole 52 is provided with a locking groove 520 adapted to the locking portion 512. The force-applying portion 511 is located outside the locking hole 52 when the bending portion 510 is fully inserted into the locking hole 52. With the help of the aforementioned snap-fit ​​structure 50, locking and unlocking of the second end of the cover buckle 40 on the connecting seat 30 can be easily achieved. The specific operation is as follows: To lock the second end of the cover buckle 40 to the connecting seat 30, the force-applying part 511 can be pinched to deform the bending part 510, which then inserts into the snap hole 52. After the bending part 510 is fully inserted into the snap hole 52, the force-applying part 511 is released, and the bending part 510 returns to its original shape under the action of elasticity. Its snap-fit ​​part 512 then snaps into the locking groove 520, thereby locking the second end of the cover buckle 40 to the connecting seat 30. Conversely, to unlock, simply pinch the force-applying part 511 again to deform the bending part 510, and the snap-fit ​​part 512 will disengage from the locking groove 520, completing the unlocking process.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
