Description

Technical Field

[0001] This utility model relates to the field of signal conversion device technology, specifically to an IO signal conversion device for a PLC controller. Background Technology

[0002] In the prior art, a patent with authorization announcement number CN221080543U and titled "An I / O Signal Adapter Device for a PLC Controller" includes an I / O signal adapter body, connectors, a guide frame, a movable plate, and a stop block. Several connectors are equidistantly spaced on one side of the I / O signal adapter body. A guide frame is installed on the side of the I / O signal adapter body near the connectors, and a movable plate is movably mounted on the guide frame. A stop block is installed at one end of the movable plate, and a docking groove is provided above the connectors. This I / O signal adapter device for the PLC controller catches the connecting wire when it passes the first wedge block. The connecting wire then moves forward, pushing the stop block forward, and then a rotating rod is moved to engage the rotating rod inside another docking frame, thus facilitating the fixing of the connecting wire. However, in actual use, dust and other debris in the air can easily enter unused connectors, affecting their normal use later. Utility Model Content

[0003] To address the problems in the existing technology, this utility model provides an IO signal conversion device for a PLC controller.

[0004] The technical solution adopted by this utility model to solve its technical problem is an IO signal conversion device for a PLC controller, including an IO signal conversion adapter body. Multiple connectors are provided on one side of the IO signal conversion adapter body. An outer frame is fixed to the IO signal conversion adapter body. Multiple outer shells are integrally formed on one side of the outer frame. A cover plate is rotatably connected to the side of each outer shell away from the IO signal conversion adapter body. A protrusion is integrally formed on the side wall of each cover plate. A stop block is integrally formed on the side of each outer shell away from the IO signal conversion adapter body. A plug is provided on the side of each cover plate away from the IO signal conversion adapter body. Each insert has an integrally formed pry block on its side wall, and each stop block has a slot at its bottom end that matches the insert. Each insert has two guide rods fixed at its bottom end, and each guide rod is fitted with a spring. Each protrusion has two through holes that match the guide rods. Each guide rod has a limit block fixed at its bottom end. Each housing has a lower clamping block fixed inside, and each lower clamping block has a locking bolt above it. Each housing has a screw hole at its top end that matches the locking bolt. Each locking bolt has an upper clamping block rotatably connected to its bottom end. Each upper clamping block has two vertical rods fixed to its top end. Each housing has two sliding grooves inside for the vertical rods to slide up and down.

[0005] By adopting the above technical solution, the toggle block moves downward, and the top of the plug comes out of the slot at the bottom of the stop. Rotating the cover plate releases the obstruction to the plug port. The connecting wire is then threaded through the housing and inserted into the plug port. Rotating the locking bolt allows the upper and lower clamping blocks to clamp the connecting wire, facilitating its fixation. When the connecting wire needs to be removed, rotating the locking bolt in the opposite direction releases the clamping. After the connecting wire is removed, the toggle block moves towards the protrusion, and the spring is compressed by the plug. After the cover plate is closed, the toggle block is released, and the spring returns to its original state, pushing the plug away from the protrusion. The top of the plug inserts into the slot at the bottom of the stop, preventing the cover plate from rotating. The cover plate seals the housing, thus preventing dust and other debris from entering the plug port.

[0006] Specifically, each of the upper and lower clamping blocks is fixed with an anti-slip pad.

[0007] By adopting the above technical solution, rotating the locking bolt, the anti-slip pads inside the upper and lower clamping blocks are in close contact with the connecting wire, which not only improves the fixing effect of the connecting wire, but also prevents the upper and lower clamping blocks from damaging the connecting wire.

[0008] Specifically, each of the cover plates has a handle fixed to the side away from the IO signal adapter body.

[0009] By adopting the above technical solution, the handle design facilitates the rotation of the cover plate.

[0010] Specifically, a sealing gasket is fixed to the side of each cover plate away from the protrusion.

[0011] By adopting the above technical solution, the sealing gasket can improve the sealing performance between the cover plate and the outer shell.

[0012] Specifically, each of the aforementioned paddles has multiple anti-slip protrusions integrally formed on its top.

[0013] By adopting the above technical solution, the anti-slip protrusions facilitate the movement of the lever.

[0014] The beneficial effects of this utility model are:

[0015] This utility model describes an IO signal conversion device for a PLC controller. By moving a toggle block downwards, the top of the plug disengages from the slot at the bottom of the stop block. Rotating the cover releases the obstruction to the connector port. The connecting wire is then threaded through the housing and inserted into the connector port. Rotating the locking bolt clamps the connecting wire between the upper and lower clamps, facilitating its fixation. To remove the connecting wire, the locking bolt is rotated in the opposite direction to release the clamp. After the connecting wire is removed, moving the toggle block towards the protrusion causes the spring to compress and contract. Closing the cover and releasing the toggle block allows the spring to return to its original state, pushing the plug away from the protrusion. The top of the plug inserts into the slot at the bottom of the stop block, preventing the cover from rotating. The cover seals the housing, preventing dust and other debris from entering the connector port.

[0016] The present invention discloses an IO signal conversion device for a PLC controller. By rotating and tightening the locking bolt, the anti-slip pads inside the upper and lower clamping blocks are in close contact with the connecting wire, which not only improves the fixing effect of the connecting wire, but also prevents the upper and lower clamping blocks from damaging the connecting wire.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] To prevent dust and other debris from entering the socket, as one embodiment of this utility model, such as Figures 1 to 5 As shown, the present invention discloses an I / O signal conversion device for a PLC controller, comprising an I / O signal conversion adapter body 1. Multiple connectors are provided on one side of the I / O signal conversion adapter body 1. An outer frame 2 is fixed to the I / O signal conversion adapter body 1 by bolts. Multiple outer shells 3 are integrally formed on one side of the outer frame 2. A cover plate 5 is rotatably connected to the side of each outer shell 3 away from the I / O signal conversion adapter body 1. A protrusion 50 is integrally formed on the side wall of each cover plate 5. A stop block 30 is integrally formed on the side of each outer shell 3 away from the I / O signal conversion adapter body 1. An insertion block 8 is provided on the side of each insertion block 8. A toggle block is integrally formed on the side wall of each insertion block 8. 80. Each stop block 30 has a slot at its bottom that matches the insert block 8. Each insert block 8 has two guide rods 9 fixed at its bottom with adhesive. Each guide rod 9 is fitted with a spring 11. Each protrusion 50 has two through holes that match the guide rods 9. Each guide rod 9 has a limit block 10 fixed at its bottom with adhesive. Each housing 3 has a lower clamping block 7 fixed inside with adhesive. Each lower clamping block 7 has a locking bolt 4 above it. Each housing 3 has a screw hole at its top that matches the locking bolt 4. Each locking bolt 4 has an upper clamping block 6 rotatably connected to its bottom. Each upper clamping block 6 has two vertical rods 60 welded to its top. Each housing 3 has two sliding grooves for the vertical rods 60 to slide up and down.

[0026] When in use, manually move the lever 80 downwards, and the top of the plug 8 will disengage from the slot at the bottom of the stop 30. Rotating the cover 5 will release the obstruction to the plug port. Thread the connecting wire through the housing 3 and insert it into the plug port. Rotate the locking bolt 4 by hand, and the upper clamp 6 and lower clamp 7 will clamp the connecting wire, facilitating its fixation. When the connecting wire needs to be removed, rotate the locking bolt 4 in the opposite direction to release the clamping of the connecting wire. After the connecting wire is removed, move the lever 80 towards the protrusion 50. The spring 11 will be compressed and contracted by the plug 8. After covering the cover 5, release the lever 80. As the spring 11 returns to its original state, it will push the plug 8 away from the protrusion 50. The top of the plug 8 will insert into the slot at the bottom of the stop 30, preventing the cover 5 from rotating. The cover 5 will seal the housing 3, thus preventing dust and other debris from entering the plug port.

[0027] To improve the fixing effect, for example, such as Figure 5 As shown, each of the upper clamping block 6 and lower clamping block 7 has an anti-slip pad 61 fixed inside by adhesive.

[0028] To facilitate the rotation of cover plate 5, for example, as shown... Figure 4 As shown, each of the cover plates 5 has a handle 51 fixed to the side away from the IO signal adapter body 1 by adhesive.

[0029] To improve the sealing between the cover plate 5 and the housing 3, for example, such as Figure 4 As shown, each of the cover plates 5 has a sealing gasket 52 fixed to the side away from the protrusion 50 by adhesive.

[0030] For ease of maneuvering the toggle switch 80, for example, as shown... Figure 3 As shown, each of the toggle blocks 80 has multiple anti-slip protrusions integrally formed on its top end.

[0031] When using this utility model, the lever 80 is moved down by hand, and the top of the plug 8 comes out of the slot at the bottom of the stop 30. The cover plate 5 is rotated to release the obstruction to the plug port. The connecting wire is threaded into the outer shell 3 and inserted into the plug port. The locking bolt 4 is rotated by hand, and the anti-slip pads 61 in the upper clamp 6 and lower clamp 7 can fit tightly against the connecting wire, which is convenient for fixing the connecting wire.

[0032] When the connecting wire needs to be unplugged, the locking bolt 4 can be rotated in the opposite direction to release the clamp on the connecting wire. After the connecting wire is pulled out, the toggle block 80 is moved toward the protrusion 50. The spring 11 is compressed and contracted by the plug block 8. After the cover plate 5 is closed, the toggle block 80 is released. During the process of the spring 11 returning to its original state, it pushes the plug block 8 away from the protrusion 50. The top of the plug block 8 is inserted into the slot at the bottom of the stop block 30, which can prevent the cover plate 5 from rotating. The cover plate 5 seals the outer shell 3, thereby preventing dust and other debris from entering the plug port.
