[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

Multiple connection interfaces 2 are provided on the bottom of one side of the control terminal body 1. A mounting bracket 3 is fixedly connected to the side of the control terminal body 1 near the connection interfaces 2. A rotating rod 4 is rotatably connected to one side of the mounting bracket 3. A fixing plate 5 is fixedly sleeved on the surface of the rotating rod 4. Torque springs 6 are symmetrically arranged on both sides of the surface of the rotating rod 4. The two ends of the torque springs 6 are respectively fixed on the fixing plate 5 and the mounting bracket 3. Multiple U-shaped grooves 7 are opened on the side of the fixing plate 5 away from the rotating rod 4. The number and position of the U-shaped grooves 7 correspond to the number and position of the connection interfaces 2.
[0023] Insert the connector into the connection interface 2, push the fixing plate 5 upward, and make the rotating rod 4 rotate inside the mounting bracket 3. The torque spring 6 is compressed and deformed, and the connecting block 8 moves into the groove 10. The hook 9 corresponds to the slot 11 and contacts the limiting block 14. The relative sliding is generated by the contacting slope, so that the limiting block 14 moves in the movable cavity 12. The return spring 13 is compressed and contracted, and the hook 9 and the limiting block 14 engage, thereby fixing the position of the fixing plate 5 and abutting against the connector to reinforce the connection and ensure normal use.
[0024] Connecting blocks 8 are symmetrically arranged on both sides of the fixing plate 5, and hooks 9 are fixedly connected to the side of the connecting block 8 near the connecting interface 2.
[0025] The mounting bracket 3 has a groove 10 symmetrically opened on the side opposite to the control terminal body 1. The groove 10 is adapted to the connecting block 8. A slot 11 is opened on one side of the groove 10. A movable cavity 12 is opened at the end of the slot 11. A limit block 14 is slidably connected inside the movable cavity 12. The limit block 14 contacts and engages with the hook 9.
[0026] A reset spring 13 is fixedly connected between the limiting block 14 and the inner wall of the movable cavity 12. A pressing plate 15 is slidably connected inside the movable cavity 12, and the pressing plate 15 is in contact with the limiting block 14.
[0027] When disassembling the connector, press the pressing plate 15 inward and slide it inside the movable cavity 12. Due to the external force, the limiting block 14 moves inside the movable cavity 12, the limiting block 14 and the hook 9 separate, and the fixing plate 5 rebounds under the elastic force of the torque spring 6, so that the connector can be disassembled.
[0028] Multiple heat dissipation slots 16 are symmetrically provided on the upper and lower sides of the control terminal body 1. End caps 17 are symmetrically provided on the left and right sides of the control terminal body 1. Multiple heat dissipation holes 18 are provided inside the end caps 17. An installation slot 19 is provided on the side of the end cap 17 closest to the control terminal body 1. A dustproof net 20 is provided inside the installation slot 19.
[0029] By providing heat dissipation grooves 16 on both sides of the control terminal body 1, the heat generated by the internal electronic components can be dissipated during use, and the heat can be moved to the end cover 17 along the direction of the heat dissipation grooves 16, so that the heat can be dissipated to the outside through the heat dissipation holes 18, thereby ensuring that the internal temperature is at a normal level and extending the service life of the control terminal body 1.
[0030] The control terminal body 1 has a connection interface 21 on the top side near the mounting bracket 3, and threaded holes 22 are symmetrically opened on both sides of the connection interface 21.
[0031] A protective cover 23 is provided on the side of the connection interface 21 away from the control terminal body 1. Mounting blocks 24 are symmetrically arranged on both sides of the protective cover 23. Multiple protective valves 25 are provided inside the side of the protective cover 23 away from the connection interface 21.
[0032] Align the mounting blocks 24 and threaded holes 22 on both sides of the protective cover plate 23, and use screws to fix the protective cover plate 23 to the outside of the second connection interface 21. When installing the connector onto the second connection interface 21, first insert the connector into the protective valve 25, and then insert it into the second connection interface 21. In this way, the protective valve 25 and the protective cover plate 23 protect the connection and reduce the adhesion of foreign objects or dust.
[0033] This utility model provides a plug-in I / O control terminal for industrial equipment, and its specific working principle is as follows:
[0034] In use, insert the connector into the connection interface 2, push the fixing plate 5 upward, and rotate the rotating rod 4 inside the mounting bracket 3. The torque spring 6 is compressed and deformed, and the connecting block 8 moves into the groove 10. The hook 9 corresponds to the slot 11 and contacts the limiting block 14. Relative sliding occurs through the contacting slope, causing the limiting block 14 to move within the movable cavity 12. The return spring 13 is compressed and contracted. After the connecting block 8 is fully moved into the groove 10, the elastic force of the return spring 13 causes the hook 9 and the limiting block 11 to move together. 4. Engage the mounting plate 5 to fix its position and abut against the connector to reinforce the connection. Align the mounting blocks 24 and threaded holes 22 on both sides of the protective cover 23 and fix the protective cover 23 to the outside of the second connection interface 21 with screws. When installing the connector onto the second connection interface 21, first insert the connector into the protective valve 25 and then into the second connection interface 21. The protective valve 25 and the protective cover 23 protect the connection and reduce the adhesion of foreign objects or dust.
