[0032] The present invention is described in detail below with reference to the accompanying drawings.

[0033] like Figure 1-4 As shown, an electronic connector terminal deformation prevention device includes a male connector 2 and a female connector 1. The female connector 1 includes a first connecting body 11 and a second connecting body 12 coaxially formed at the outer end of the first connecting body 11. The outer diameter of the second connecting body 12 is smaller than that of the first connecting body 11. The second connecting body 12 is formed with a plurality of conductive connection ports 13.

[0034] The first connecting body 11 is provided with an axially movable guide sleeve 3 made of aluminum alloy. The female connector 1 includes a third connecting body 21 coaxially aligned with the first connecting body 11 and having the same outer diameter. The third connecting body 21 is formed with a female connecting groove 22 for inserting the second connecting body 12. A conductive column 23 inserted into the conductive connecting port 13 is provided in the female connecting groove 22; the outer wall of the first connecting body 11 is axially formed with a first guide protrusion 31, and the outer wall of the third connecting body 21 is axially formed with a second guide protrusion 32 axially aligned with the first guide protrusion 31. The guide sleeve 3 can move along the length direction of the first guide protrusion 31 and the second guide protrusion 32.

[0035] When the male connector 2 and the female connector 1 are connected, the female connection groove 22 of the female connector 1 cooperates with the second connection body 12 of the male connector 2, and the second connection body 12 is inserted into the female connection groove 22. At the same time, the conductive column 23 located in the female connection groove 22 is inserted into the conductive connection port 13 of the second connection body 12 to achieve a conductive connection; after the connection is completed, the first guide protrusion 31 located on the first connection body 11 is coaxially aligned with the second guide protrusion 32 of the third connection body 21. At this time, the guide sleeve 3 can be slid, and the guide sleeve 3 moves between the first connection body 11 and the third connection body 21. The guide sleeve 3 can ensure the stability of the first connection body 11 and the third connection body 21 after connection, prevent deformation of the conductive terminal, and ensure the stability of conduction.

[0036] Specifically, an elastic structure 35 that elastically contacts the conductive column 23 is provided in the conductive connection port 13. The elastic structure 35 includes an elastic groove 36 opened in the conductive connection port 13. The elastic groove 36 is installed with a metal conductive sheet 37 that can elastically surround the conductive column 23. The metal conductive sheet 37 is installed in the elastic groove 36 by a compression spring. Under the elastic drive of the compression spring, it can move radially inward; in addition, the two ends of the metal conductive sheet 37 are respectively formed with a flared guide structure to facilitate the insertion of the conductive column 23 without causing the problem of stopping; after some conductive columns 23 are inserted into the conductive connection port 13, their gaps are large, affecting their conductive performance. At this time, the elastic structure 35 located in the conductive connection port 13 works, and the metal conductive sheet 37 located in the elastic groove 36 moves radially, so that the metal conductive sheet 37 is in surface contact with the conductive column 23, ensuring that conductive columns 23 with different outer diameters can conduct electricity after being inserted into the conductive connection port 13, preventing power outages.

[0037] Preferably, the number of elastic grooves 36 is more than two, and two adjacent elastic grooves 36 are arranged in a ring shape and equidistantly in the conductive connection port 13, and the curvature of the metal conductive sheet 37 is adapted to the inner diameter of the guide connection port; multiple metal conductive sheets 37 move elastically radially inward at the same time to achieve surface contact with the conductive column 23, thereby ensuring conductive stability.

[0038] Preferably, the outer wall of the second connecting body 12 is formed with an anti-fool protrusion 33 along the axial direction, and the number of the anti-fool protrusions 33 is multiple; the inner ring wall of the female connecting groove 22 is formed with an anti-fool slide groove 34 along the axial direction that slides with the anti-fool protrusion 33; when the second connecting body 12 is matched with the female connecting groove 22, the anti-fool protrusion 33 and the anti-fool slide groove 34 need to be coaxially aligned, and then the corresponding conductive column 23 and the conductive connecting port 13 can be aligned accordingly, which can prevent the wrong position from being inserted and realize the anti-fool connection.

[0039] Furthermore, a conductive mounting plate 24 is provided within the female connection slot 22 for mounting a conductive post 23. The conductive post 23 is a cylindrical bar structure, and is removably fitted with a conductive sleeve 25. The outer diameter of the conductive post 23 can be adjusted via the conductive sleeve 25. This allows the metal conductive sheet 37 to better contact the conductive sleeve 25 of the conductive post 23 after the conductive post 23 is inserted into the conductive connection port 13, increasing the contact area and further ensuring conductive stability.

[0040] Preferably, one end of the conductive sleeve 25 is provided with a snap-fit ​​structure connected to the conductive mounting plate 24; the conductive sleeve 25 can be detachably connected to the conductive mounting plate 24 through the snap-fit ​​structure, and when there is no need to increase the outer diameter of the conductive column 23, the conductive sleeve 25 can be detached through the snap-fit ​​structure.

[0041] It should be noted that the snap-fit ​​structure includes a male fastener 26 installed on the conductive mounting plate 24 and a female fastener 27 installed on one end of the conductive sleeve 25. The male fastener 26 and the female fastener 27 are detachable and connected to each other. This is a common existing technology on the market, and the specific structure will not be described in detail here.

[0042] The first connector 11 is connected to a wire harness enclosure 14 at its rear end. This enclosure is formed with an external thread 15. The wire harness enclosure 14 includes a wire harness connector 16 that is threadably connected to the external thread 15 at the rear end of the first connector 11. A silicone sheath 17 is attached to the rear end of the wire harness connector 16. The silicone sheath 17 softly encloses a set of wire harnesses, preventing them from becoming disorganized and ensuring circuit stability.

[0043] In summary, it can be seen that the present invention has the above-mentioned excellent characteristics, which can enhance its performance unprecedented in the past and become a product with great practical value.

[0044] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there may be changes in the specific implementation methods and application scope. The content of this specification should not be understood as limiting the present invention.
