[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0032] Refer to Figures 1 to 3, An embodiment provided by the present utility model: An electrical terminal connector with a self-locking function, including a connector head 1 and a terminal wire 6. The left end of the connector head 1 is fixedly connected to a port sleeve 2. The connector head 1 is the core part of the entire electrical connector, which is responsible for connecting with the terminal wire 6 and realizing data transmission. The right side of the terminal wire 6 is engaged with the left end of the port sleeve 2. The function of the port sleeve 2 is to protect the connector head 1 and provide a connection interface with the terminal wire 6. The terminal wire 6 is another part of the connector, which is responsible for transmitting electrical signals or data to the connector head 1. The right end of the terminal wire 6 is connected by engaging with the left end of the port sleeve 2.

[0033] The left end of the port sleeve 2 is fixedly connected to a protective sleeve 3. The left end of the port sleeve 2 is fixedly connected to a protective sleeve 3. The function of the protective sleeve 3 is to further protect the connection part of the connector head 1 and the terminal wire 6. A conical ring 4 is fixedly connected to the middle inside of the protective sleeve 3. The left end of the port sleeve 2 is fixedly connected to the right end of the conical ring 4. A plurality of notches 5 are provided on the inner side of the middle of the conical ring 4. A conical ring 4 is fixedly connected to the middle inside of the protective sleeve 3. The design of the conical ring 4 is used to help realize the self-locking function of the terminal wire 6. A plurality of notches 5 are provided on the inner side of the middle of the conical ring 4. The existence of these notches 5 allows the conical ring 4 to deform under specific conditions, thus completing the self-locking function.

[0034] Reference Figure 2 and Figure 4 , A fixing sleeve 7 is fixedly connected to the outside of the right end of the terminal wire 6. The fixing sleeve 7 is not only responsible for contacting with the conical ring 4, but also slidably connected inside the protective sleeve 3. The outside of the fixing sleeve 7 is slidably connected to the inner wall of the conical ring 4. The outside of the fixing sleeve 7 is slidably connected inside the protective sleeve 3. A groove 8 is provided on the outside of the fixing sleeve 7. The function of this groove 8 is to engage with the outer side inner wall of the conical ring 4 to help lock the terminal wire 6.

[0035] The outer side inner part of the conical ring 4 is engaged with the inner wall of the groove 8. Through holes 9 are provided on both the front and rear sides of the outside of the fixing sleeve 7. A sliding block 10 is slidably connected inside the groove 8. The sliding block 10 is slidably connected to the inner wall of the groove 8. A pushing block 11 is slidably connected to the inner wall of the through hole 9. Pushing blocks 11 are fixedly connected to both the upper and lower sides of the sliding block 10. Pushing blocks 11 are fixedly connected to both the upper and lower sides of the sliding block 10. The pushing block 11 is slidably connected to the inner wall of the through hole 9. The sliding of the pushing block 11 can drive the sliding block 10 to move, thereby adjusting the state of the conical ring 4 and realizing the switching between self-locking and release.

[0036] An external reset spring 12 is sleeved on the fixed sleeve 7. One end of the reset spring 12 is fixedly connected to the right end inside the sliding block 10, and the other end of the reset spring 12 is fixedly connected to the left end of the inner wall of the groove 8. The function of the reset spring 12 is that when the end wire 6 is pulled out, the elastic potential energy of the spring is used to reset the sliding block 10 and the pushing block 11. This ensures that the connector can return to its initial state after each plugging and unplugging operation, facilitating the next insertion.

[0037] Reference Figure 5 , a protective component for protecting the end wire 6 is arranged in the middle of the outside of the end wire 6. The protective component includes a protective sleeve 13, an annular spring 14 and a rubber ring 15. The protective sleeve 13 is fixedly connected to the outside of the right side of the end wire 6, and the right end of the protective sleeve 13 is fixedly connected to the left end of the fixed sleeve 7. The protective sleeve 13 is fixedly connected to the left end of the fixed sleeve 7, and its function is to provide additional physical protection to prevent damage to the end wire 6. An annular spring 14 is fixedly connected to the middle of the inside of the protective sleeve 13, and a rubber ring 15 is sleeved on the outside of the annular spring 14. This design provides additional shockproof and protective functions to reduce the impact of external shocks on the end wire 6.

[0038] A bending sleeve 16 is slidably connected to the outside of the left side of the end wire 6. A plurality of arc-shaped grooves 17 are arranged on the outside of the bending sleeve 16. The left end of the bending sleeve 16 is fixedly connected to the left end of the protective sleeve 13. The design of the arc-shaped grooves 17 allows the bending sleeve 16 to be properly folded when the end wire 6 is pulled externally, reducing potential electrical safety hazards caused by cable breakage or damage.

[0039] Working principle: When in use, one end of the end wire 6 drives the fixed sleeve 7 to be inserted into the protective sleeve 3, and the end wire 6 is inserted into the connector head 1 in the port sleeve 2, thereby realizing data connection. When the end wire 6 is inserted into the protective sleeve 3, the right side of the fixed sleeve 7 fixedly connected to the outside of the end wire 6 will first contact the conical ring 4. At this time, because a notch 5 is opened on the inner side of the conical ring 4, when the fixed sleeve 7 abuts against the conical ring 4, it will drive the conical ring 4 to expand and then retract into the groove 8, and engage with the right side of the groove 8 of the fixed sleeve 7, thereby realizing the self-locking of the end wire 6 and the connector head 1 and ensuring the stable transmission of data.

[0040] When the user needs to disassemble the connector, the sliding block 10 can be driven to slide in the groove 8 by sliding the pushing block 11, and the pushing block 11 slides in the through hole 9. The right side of the sliding block 10 abuts against the inner side of the conical ring 4, causing the conical ring 4 to expand again, and the sliding block 10 overlaps with the groove 8, ensuring the external integrity of the fixed sleeve 7, so that the end wire 6 can be pulled out of the protective sleeve 3 and the port sleeve 2. After being pulled out, the elastic potential energy of the reset spring 12 drives the sliding block 10 and the pushing block 11 to reset, so that the position of the end wire 6 can be inserted and installed again.

[0041] When the end wire 6 is pulled or dragged externally, the outside of the end wire 6 will squeeze the annular spring 14 to squeeze the rubber ring 15, and the arc-shaped groove 17 on the bending sleeve 16 sleeved on the outside of the end wire 6 will fold accordingly, reducing the potential electrical safety hazards caused by cable breakage or damage.

[0042] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
