[0027] like Figures 1-4 As shown, this utility model embodiment provides a connection structure for the internal ribbon cable of the PCB board and the power supply housing, including a connection component 1. The connection component 1 includes a housing 11, a connection ribbon cable 12, a connection plug 13, a PCB board 14, a connection slot 15, a limiting slot 16, a plug block 17, a threaded pull rod 18, a plug hole 19, a pull button 20, and a limiting nut 21.

[0028] A connecting cable 12 is provided on one side of the interior of the housing 11. The output end of the connecting cable 12 is electrically connected to a connector 13. A PCB board 14 is provided on the other side of the interior of the housing 11. A connecting slot 15 is provided on the upper surface of the PCB board 14 near the connecting cable 12. The outer side wall of the connector 13 is slidably connected to the inner side wall of the connecting slot 15. Limiting grooves 16 are formed at the center of the inner front wall and inner rear wall of the connecting slot 15. Insert blocks 17 are slidably connected to the inner side walls of the two limiting grooves 16. The centers of the two opposite sides of the two insert blocks 17 are fixedly connected. There are threaded pull rods 18, with the far ends of the two threaded pull rods 18 passing through the center of the far side of the inner sidewall of the two limiting grooves 16 respectively. The center of the front and rear surfaces of the connector 13 is provided with insertion holes 19. The near ends of the outer sidewalls of the two plug blocks 17 are slidably connected to the inner sidewalls of the two insertion holes 19 respectively. The far ends of the two threaded pull rods 18 are fixedly connected with pull buttons 20. The side of the outer sidewall of the threaded pull rod 18 near the pull button 20 is threadedly connected with a limiting nut 21. The connector 13 is limited and fixed by inserting the plug blocks 17 into the insertion holes 19.

[0029] In one embodiment, specifically: the outer side wall of the threaded pull rod 18 is sleeved with a spring 22 near one side of the insertion block 17, one end of the spring 22 is connected to the outer side of the insertion block 17 near the threaded pull rod 18, and the other end of the spring 22 is connected to the outer side of the inner side wall of the limiting groove 16 near the center of one side of the insertion block 17. Through the pushing force of the spring 22, the insertion block 17 is conveniently reset and inserted into the insertion hole 19, thereby limiting the connection of the connector 13.

[0030] In one embodiment, specifically: the outer side wall of the threaded pull rod 18 is sleeved with a spring 22 near one side of the insertion block 17, one end of the spring 22 is connected to the outer side of the insertion block 17 near the threaded pull rod 18, and the other end of the spring 22 is connected to the outer side of the inner side wall of the limiting groove 16 near the center of one side of the insertion block 17. Through the pushing force of the spring 22, the insertion block 17 is conveniently reset and inserted into the insertion hole 19, thereby limiting the connection of the connector 13.

[0031] In one embodiment, specifically: the inner bottom wall of the connection slot 15 is provided with a plurality of connection grooves 24, and the inside of each of the plurality of connection grooves 24 is provided with an elastic connecting piece 25. The lower surface of the connector 13 is provided with a plurality of mounting grooves 26, and the inner top wall of each of the plurality of mounting grooves 26 is fixedly connected with a conductive connecting piece 27. The top of the elastic connecting piece 25 is connected to the lower surface of the conductive connecting piece 27. Through the connection of the elastic connecting piece 25 and the conductive connecting piece 27, electrical connection is realized, and the signal and power transmission requirements are met.

[0032] In one embodiment, specifically: the inner side wall of the housing 11 is fixedly connected with a positioning column 28 at the front and rear of the side away from the connection cable 12. The connector 13 is provided with a positioning hole 29 at the front and rear of the side away from the connection cable 12. The outer side wall of the positioning column 28 is slidingly connected to the inner side wall of the positioning hole 29. Through the cooperation of the positioning column 28 and the positioning hole 29, the preliminary positioning function is realized, the connector 13 is accurately inserted into the connection slot 15, and the connection position accuracy is ensured.

[0033] In one embodiment, specifically: one end of the conductive connecting piece 27 is electrically connected to the output end of the connection cable 12. Through the connection of the conductive connecting piece 27 and the connection cable 12, the electrical connection of the conductive connecting piece 27 and the connection cable 12 is realized.

[0034] In one embodiment, specifically: two of the insertion blocks 17 are provided with inclined surfaces 30 on the side close to each other, and the insertion blocks 17 slide into the limiting grooves 16 under the guidance of the inclined surfaces 30 when a force is applied.

[0035] In one embodiment, specifically: one end of the elastic connecting piece 25 is electrically connected to the input end of the PCB board 14, and the electrical connection between the elastic connecting piece 25 and the PCB board 14 is facilitated by the connection between the elastic connecting piece 25 and the PCB board 14.

[0036] When the utility model works: when the connection plug 13 is inserted, the connection plug 13 is slowly pushed into the connection slot 15 on the PCB board 14, and the front end of the connection plug 13 touches the inclined surface 30 on the insertion block 17. Due to the guidance of the inclined surface 30, as the connection plug 13 continues to penetrate, an extrusion force is applied to the insertion block 17 towards the inside of the limiting groove 16, and the insertion block 17 slides into the limiting groove 16 under the force, and the spring 22 sleeved on the outer sidewall of the threaded pull rod 18 is compressed. Until the connection plug 13 is completely inserted into the connection slot 15, it is automatically locked: when the connection plug 13 is inserted in place, the insertion hole 19 at the center of the front and rear surfaces of the connection plug 13 is aligned with the insertion block 17, and at this time, the compressed spring 22 restores to its original state, releases the elastic force, and pushes the insertion block 17 to slide along the limiting groove 16 to the inside of the connection slot 15. The outer sidewall of the insertion block 17 is accurately inserted into the corresponding insertion hole 19, and the connection plug 13 is firmly locked by this mechanical limiting mode, effectively preventing accidental loosening and falling out during equipment operation, and ensuring the stability of the connection. In the process of inserting the connection plug 13 into the connection slot 15, the elastic connecting piece 25 in the connecting groove 24 on the inner bottom wall of the connection slot 15 is tightly attached to the conductive connecting piece 27 in the mounting groove 26 on the lower surface of the connection plug 13. Since the conductive connecting piece 27 is electrically connected to the output end of the connection cable 12, and the elastic connecting piece 25 is electrically connected to the input end of the PCB board 14, the mechanical connection is stable, and the electrical connection is also successfully achieved, meeting the signal and power transmission requirements. If the connection plug 13 is to be removed, first pull the pull knob 20 to move the threaded pull rod 18 away from the connection slot 15, so that the insertion block 17 overcomes the elastic force of the spring 22 and retracts to the deep part of the limiting groove 16, then rotate the limiting nut 21 to move it towards the insertion block 17 until it is close to the insertion block 17, so that the insertion block 17 is maintained in the retracted state, the locking of the connection plug 13 is released, and then the connection plug 13 can be easily pulled out.

[0037] The above merely describes a specific implementation of the present application, but the protection scope of the present application is not limited thereto, and any skilled person in the art can easily think of various changes or replacements within the technical range disclosed by the present application, which should be encompassed in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
