[0021] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0022] This application discloses a cable connector. For example... Figure 1 , Figure 2 As shown, it includes a male terminal 1 and a female terminal 2. The male terminal 1 is provided with a protrusion 3 and the female terminal 2 is provided with a recess 4. The protrusion 3 and the recess 4 are inserted into each other. A sealing groove is provided on the insertion surface of the protrusion 3 and the recess 4, and a nitrile rubber sealing ring is built in. When the protrusion 3 is fully inserted into the recess 4, the sealing ring is compressed to achieve waterproof and dustproof. A retaining plate 5 is also provided on the male terminal 1 at the same end of the protrusion 3, and a retaining groove 7 is provided on the female terminal 2. One end of the retaining plate 5 is engaged with the retaining groove 7.

[0023] The female terminal 2 is provided with a sliding groove 6. One end of the sliding groove 6 is connected to the slot 7. The end of the sliding groove 6 away from the slot 7 is set as an inclined surface 8. The inclined surface 8 guides the movement of the card plate 5, which facilitates the quick engagement of the card plate 5 and the slot 7. The card plate 5 and the sliding groove 6 are slidably set. A fixing component is provided between the card plate 5 and the female terminal 2. The fixing component includes a limiting ring 9, which is made of high-strength engineering plastic.

[0024] See Figure 1 , Figure 3 As shown, the limiting ring 9 is fitted onto the female terminal 2. Guide grooves 16 are provided on both sides of the female terminal 2. A slide rod 17 is slidably arranged inside the guide groove 16. One end of the slide rod 17 is installed on the limiting ring 9. Through the mutual cooperation between the slide rod 17 and the guide groove 16, the movement distance of the limiting ring 9 is limited, preventing the limiting ring 9 from disengaging from the female terminal 2, and guiding the movement direction of the limiting ring 9.

[0025] The limiting ring 9 is hollow, and each of the limiting rings 9 on both sides of the protrusion 10 is provided with a strip hole 14. When the area between the protrusion 10 and the two strip holes 14 is subjected to pressure, it can move completely inward to the limiting ring 9, which facilitates the separation of the protrusion 10 from the fixing hole 11. Push plates 13 are installed on both sides of the limiting ring 9. The outer surface of the push plate 13 is provided with anti-slip texture, and the push plate 13 is triangular.

[0026] See Figure 2 , Figure 3 , Figure 4 As shown, one end of the push plate 13 is fixedly connected to the outer ring of the limiting ring 9. A pressure plate 15 is installed on the side of the push plate 13 near the inner ring of the limiting ring 9. The pressure plate 15 contacts the area of ​​the limiting ring 9 between the two strip holes 14. A disassembly groove 18 is provided on the male terminal 1, and a disassembly groove 19 is provided on the female terminal 2. The disassembly groove 19 is connected to the slide groove 6. When the push plate 13 is pressed, sufficient space for movement is provided by the disassembly groove 18 and the disassembly groove 19, thereby achieving the effect of conveniently driving the bending of the area of ​​the limiting ring 9 between the two strip holes 14.

[0027] See Figure 3 As shown, the positions of disassembly groove 2 19 and disassembly groove 18 correspond to the push plate 13. Multiple protrusions 10 are provided, and the multiple protrusions 10 are evenly distributed. At least two protrusions 10 are provided. The inner ring of the limiting ring 9 is provided with protrusions 10. The card plate 5 at the corresponding position of the protrusions 10 is provided with fixing holes 11. The protrusions 10 are engaged with the fixing holes 11. The female terminal 2 is provided with limiting holes 12. The protrusions 10 and the limiting holes 12 are also engaged.

[0028] The implementation principle of a cable connector in this application embodiment is as follows: During installation, the protrusion 3 of the male terminal 1 is first aligned with the concave part 4 of the female terminal 2. The initial positioning of the male terminal 1 and the female terminal 2 is achieved by the insertion of the protrusion 3 and the concave part 4. At the same time as the protrusion 3 and the concave part 4 are inserted, the retaining plate 5 on the male terminal 1 slides along the slide groove 6 of the female terminal 2. Under the guidance of the inclined surface 8, the retaining plate 5 smoothly slides into the interior of the slide groove 6 and finally engages with the retaining groove 7 at the end of the slide groove 6, forming a second layer of fixation between the male terminal 1 and the female terminal 2, further restricting the relative displacement between the two.

[0029] After the card plate 5 and the card slot 7 are engaged, the push plates 13 on both sides of the limiting ring 9 are operated to push the limiting ring 9 to slide along the female terminal 2, so that the protrusion 10 is separated from the limiting hole 12. At this time, the guide grooves 16 on both sides of the female terminal 2 cooperate with the slide rods 17 on the limiting ring 9 to ensure that the limiting ring 9 slides stably without deviating from the trajectory. As the limiting ring 9 slides, the protrusion 10 on its inner side gradually engages with the fixing hole 11 on the card plate 5 to achieve the third fixation.

[0030] During disassembly, the push plate 13 is pressed using the operating space provided by the disassembly groove 18 of the male terminal 1 and the disassembly groove 19 of the female terminal 2. The push plate 13 rotates on the limiting ring 9 and pushes the designated area of ​​the limiting ring 9 through the pressure plate 15, thereby causing the protrusion 10 to separate from the fixing hole 11. At the same time, the push plate 13 is pushed to drive the limiting ring 9 to slide in the opposite direction along the guide groove 16, and the locking state of the fixing component is released.

[0031] The card plate 5 can slide in the opposite direction along the slide groove 6 and exit from the card groove 7, releasing the second layer of fixation between the male terminal 1 and the female terminal 2. At the same time, the protrusion 3 of the male terminal 1 is pulled out from the concave part 4 of the female terminal 2, completing the complete separation of the male terminal 1 and the female terminal 2.

[0032] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
