DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0031] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0032] like Figure 1-Figure 4 As shown, an anti-dropping electrical connector provided by an embodiment of the present invention includes a connecting seat 1, and also includes:

[0033] An insulating support 12, wherein the insulating support 12 is fixed to the middle of the connecting base 1, and a plurality of insulating sleeves 16 are fixed to the insulating support 12, and the insulating sleeves 16 are used for sleeve connection with the conductive ring 11 fixed at the end of the core 6 of the connecting wire 5;

[0034] Centering fixing components 9, centering fixing components 9 are also fixed on the connecting base 1 on both sides of the insulating support 12, and the centering fixing components 9 are used to elastically clamp and fix the connecting wire 5 in the center;

[0035] A cover shell 8 is provided on the connecting seat 1 in a detachable manner, and a crimping assembly 13 corresponding to an insulating sleeve 16 on the insulating support 12 is fixed on the inner top of the cover shell 8, and the crimping assembly 13 includes a crimping cylinder 17, a centering column 18, a buffer cylinder 20, a slide 21 and an elastic member 22. The buffer cylinder 20 is fixed to the inner top of the cover shell 8, and a slide 21 is slidably provided on the inner side of the buffer cylinder 20. The inner side of the buffer cylinder 20 is also provided with an elastic member 22 for elastically supporting the slide 21. The crimping cylinder 17 is fixed on the lower side of the slide 21, and the centering column 18 is fixed on the inner side of the crimping cylinder 17. When the cover shell 8 and the connecting seat 1 are fixed together, the crimping cylinder 17 is sleeved on the outer side of the insulating sleeve cylinder 16 and presses and fixes the conductive ring 11, and the centering column 18 is inserted into the inner side of the insulating sleeve cylinder 16.

[0036] In the embodiment of the present invention, the arrangement of the insulating support 12 and the insulating sleeve 16 facilitates the corresponding connection of multiple cores 6 of the connecting line 5. It is only necessary to pre-fix the conductive ring 11 at the end of the core 6 and sleeve the conductive ring 11 on the insulating sleeve 16 to prevent it from falling off reliably.

[0037] During assembly, the cover 8 is removed, and then the two connecting wires 5 to be connected are respectively fixed on the centering fixing components 9 on both sides of the insulating support 12. The centering fixing components 9 can be used to elastically clamp and fix the connecting wires 5 in the center. Then, after the cover 8 is aligned with the connecting seat 1, the crimping component 13 can correspond to the insulating sleeve 16. As the cover 8 and the connecting seat 1 are fixed together, the crimping sleeve 17 is sleeved on the outside of the insulating sleeve 16 and presses and fixes the conductive ring 11. At the same time, the centering column 18 is inserted into the inside of the insulating sleeve 16, realizing a reliable and anti-disconnection electrical connection of the connecting wires 5 on both sides.

[0038] It is worth noting that the limited elastic member 22 can elastically support the crimping tube 17, so that the crimping tube 17 can press and fix the conductive ring 11 reliably. At the same time, the combination of the crimping tube 17 and the centering column 18 reduces the difficulty of installing the crimping tube 17 on the insulating sleeve tube 16, and has a good positioning and anti-slip effect, thereby improving the overall reliability of the connector.

[0039] like Figure 1-Figure 4 As shown, as a preferred embodiment of the present invention, the insulating sleeve tube 16 and the crimping tube 17 both adopt a cylindrical barrel structure, and the inner diameter of the crimping tube 17 is larger than the outer diameter of the insulating sleeve tube 16, which is conducive to the convenient connection of the crimping tube 17 on the insulating sleeve tube 16 and reduces the difficulty of installing the cover shell 8 and the connecting seat 1.

[0040] The centering column 18 adopts an inverted cone structure, and an elastic layer 19 is also provided on the outer side of the centering column 18, which is convenient for the centering column 18 to be inserted into the inner side of the insulating sleeve 16. At the same time, the elastic layer 19 facilitates the central insertion, and at the same time, the conductive rings 11 of different thicknesses or quantities are adapted to be sleeved on the insulating sleeve 16, that is, the elastic layer 19 and the elastic member 22 cooperate to serve as a buffer margin for a wide range of adaptation, which will not be elaborated.

[0041] In addition, the elastic member 22 is preferably a spring; when there is no external force, under the elastic force of the elastic member 22, the slide seat 21 elastically abuts against the inner bottom of the buffer tube 20; when the cover shell 8 and the connecting seat 1 are matched and fixed, the elastic member 22 is compressed, and the crimping tube 17 elastically abuts and fixes the conductive ring 11 together, and the lowermost conductive ring 11 abuts against the insulating support 12, so that after the cover shell 8 and the connecting seat 1 are installed, the crimping tube 17 abuts against the conductive ring 11, and the elastic member 22 is compressed, thereby achieving reliable fixation.

[0042] The connection structure between the cover shell 8 and the connecting seat 1 is as follows: the outer ring of the connecting seat 1 is fixed with a sealing ring 15 adapted to the cover shell 8, and the front and rear sides of the cover shell 8 are provided with fixing flanges 2, and the fixing flanges 2 on the front and rear sides of the cover shell 8 are connected and fixed to the connecting seat 1 by fastening bolts 3, and the sealing ring 15 is used to realize the sealing fixation of the cover shell 8 and the connecting seat 1; the middle parts of the two ends between the cover shell 8 and the connecting seat 1 are respectively provided with an upper elastic sealing ring 7 and a lower elastic sealing ring 4, and the lower elastic sealing ring 4 is fixedly connected with the sealing ring 15, and the upper elastic sealing ring 7 and the lower elastic sealing ring 4 are abutted to form a wire hole 10 for the connecting line 5 to pass through, and when the cover shell 8 and the connecting seat 1 are fixed, the inner rings of the upper elastic sealing ring 7 and the lower elastic sealing ring 4 are elastically sealed and abutted with the surface of the connecting line 5, so as to ensure the reliability of the seal and achieve a certain dustproof and waterproof effect.

[0043] like Figure 5-Figure 8 As shown, as a preferred embodiment of the present invention, the centering and fixing component 9 includes a centering support 14, an elastic telescopic member 24 and an anti-slip splint 25. The centering support 14 is fixed on the connecting seat 1. A centering groove 23 is provided in the middle of the top of the centering support 14. The centering groove 23 facilitates the centering positioning of the connecting line 5. The front and rear ends of the centering support 14 are relatively fixed with elastic telescopic members 24. The telescopic end of the elastic telescopic member 24 is fixed with an anti-slip splint 25. The elastic telescopic member 24 and the anti-slip splint 25 cooperate to elastically clamp the connecting line 5 and fix it on the centering groove 23.

[0044] Preferably, the centering groove 23 adopts an arc-shaped concave structure in the middle, the anti-slip splint 25 adopts an arc-shaped structure, and the surface of the centering groove 23 and the side of the anti-slip splint 25 away from the elastic telescopic part 24 are provided with an anti-slip layer (not shown), thereby improving the reliability of clamping and preventing the connecting line 5 from slipping.

[0045] Preferably, the elastic telescopic member 24 includes an elastic member 26, an arc outer cylinder 27, anti-slip teeth 28, a slide plate 29, an arc telescopic rod 30 and an elastic telescopic ball 32. The arc outer cylinder 27 is fixed on the centering support 14. A slide plate 29 is slidably provided on the inner side of the arc outer cylinder 27. The arc telescopic rod 30 is fixed on the slide plate 29. The arc telescopic rod 30 slides out from the end of the arc outer cylinder 27. The anti-slip splint 25 is fixed to the end of the arc telescopic rod 30. The arc outer cylinder 27 is also provided with an elastic member 26 for elastically supporting the slide plate 29. The elastic member 26 adopts a spring. The inner wall of the arc outer cylinder 27 is also fixed with an anti-slip tooth 28. The outer side of the slide plate 29 is provided with a slide groove 31 slidably connected to the anti-slip tooth 28. The slide groove 31 is fixed with a spring connected to the anti-slip tooth 28. The elastic telescopic ball 32 cooperates with the anti-slip teeth 28, and the anti-slip teeth 28 are preferably arranged with a large inclination on one side and a small inclination on the other side (similar to the characteristics of a ratchet gear, the difference is that the elastic telescopic ball 32 can be telescoped, and when a reverse thrust is applied, the slide plate 29 can move in the opposite direction, which is not elaborated here). In this way, under the elastic force of the elastic member 26, the elastic telescopic ball 32 can shrink when it touches the anti-slip teeth 28, meeting the requirement of extending the arc telescopic rod 30, and at the same time, the anti-slip teeth 28 are used to limit the elastic telescopic ball 32, thereby ensuring the reliability of the anti-slip splint 25 fixing the connecting line 5. It is necessary to manually apply a large force to make the elastic telescopic ball 32 shrink and slide through the anti-slip teeth 28, thereby releasing the fixation of the anti-slip splint 25 to the connecting line 5, and the reliability is high.

[0046] In addition, if Figure 6 As shown, in actual application, the anti-slip splint 25 on one side can be moved, and the connecting wire 5 can be inserted between the two anti-slip splints 25 and the centering groove 23, which is convenient and quick; the connecting wire 5 can also be pressed between the two anti-slip splints 25, and the two anti-slip splints 25 can be separated and inserted by using the connecting wire 5, which may cause slight damage to the epidermis of the connecting wire 5. You can choose as needed.

[0047] The above embodiment of the present invention provides an anti-dropping electrical connector, and its working principle is summarized as follows:

[0048] First, a conductive ring 11 is pre-fixed at the end of the core 6 of the connecting wire 5. The conductive ring 11 is sleeved into the insulating sleeve 16 on the insulating support 12, thereby achieving a preliminary connection between the core 6 and the connector. This process is completed by directly sleeve-fitting the conductive ring 11 onto the insulating sleeve 16, which is simple and quick.

[0049] In order to ensure that the connecting wire 5 can maintain a centered position during the connection process and avoid poor connection caused by deviation, centering fixing components 9 are provided on both sides of the connecting seat 1. These components preliminarily position the connecting wire 5 through the centering groove 23 on the centering support 14, and ensure that the connecting wire 5 is firmly maintained in the center position through the elastic clamping effect of the anti-dropping clamp 25.

[0050] When the housing 8 is aligned and fixed with the connection base 1, the crimping assembly 13 inside the housing 8 begins to function. The crimping barrel 17 is sleeved on the outside of the insulating sleeve barrel 16 and exerts pressure on the conductive ring 11, tightly fixing it on the insulating sleeve barrel 16. At the same time, the centering column 18 in the crimping barrel 17 is inserted into the inside of the insulating sleeve barrel 16, further enhancing the stability of the connection. The elastic member 22 (such as a spring) here ensures that the crimping barrel 17 can effectively press and fix the conductive ring 11, and maintain a good connection state even under external vibrations.

[0051] The sealing structure between the housing 8 and the connector 1 (including the sealing ring 15, the upper elastic sealing ring 7 and the lower elastic sealing ring 4) not only helps prevent dust and moisture from invading the interior of the connector and affecting the electrical performance, but also increases the service life of the entire device. These sealing components work together to form an effective protective barrier.

[0052] In summary, the anti-drop-off electrical connector achieves efficient and stable connection between the connecting wire 5 and the connector, and at the same time has good dustproof and waterproof performance, and is suitable for electrical connection needs in various environments.

[0053] The circuits, electronic components and modules involved are all prior art and can be fully implemented by those skilled in the art. Needless to say, the content protected by the present invention does not involve improvements to software and methods.

[0054] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
