[0002] At present, connectors are often called circuit connectors or electrical connectors. They are conductor devices that can bridge two conductors on a loop so that current or signals can flow from one conductor to another. Usually, connectors include female connectors and male connectors. The male connector is inserted into the female connector to achieve signal connection between the male connection module and the female connection module. If the female connector and the male connector become loose or are unexpectedly unplugged, it will affect the normal use of the female connector and the male connector, resulting in safety hazards.

[0003] Existing electrical connectors generally use manual screwing to achieve connection through threading. However, after the female connector and the male connector are plugged into each other, the female connector and the male connector need to be firmly connected together by manually tightening the nut. When unplugging, the female connector and the male connector also need to be manually loosened before the nut can be separated. This connection method is cumbersome, inconvenient and time-consuming to operate, and the nut can easily fall off due to aging after long-term use, causing it to become loose or fall off, affecting its use.

[0004] Therefore, it is necessary to develop a new technology to solve the above problems. Utility Model Content

[0036] Please refer to Figures 1 to 5 as shown, which shows the specific structure of the embodiment of the present utility model

[0037] A buckle-type connector assembly includes a male connector 10 and a female connector 20. The male connector 10 is pluggable on the female connector 20. The male connector 10 includes a male main body 11 and a first terminal 12. The male main body 11 has a plugging cavity 13. One end of the first terminal 12 extends into the male main body 11, and the other end extends into the plugging cavity 13. The female connector 20 includes a female main body 21 and a second terminal 22. The female main body 21 has an embedding part 23. The embedding part 23 has an assembly hole 24. One end of the second terminal 22 extends into the female main body 21, and the other end extends to the assembly hole 24. The embedding part 23 is inserted into the plugging cavity 13, and the first terminal 12 is inserted into the plugging hole 221 of the second terminal 22. In this embodiment, four first terminals 12 are provided. Correspondingly, four second terminals 22 are provided. The four first terminals 12 are arranged at intervals, and the four second terminals 22 are arranged at intervals. An anti-fooling convex part 14 protrudes in the plugging cavity 13. One end of the embedding part 23 facing the male main body 11 has an anti-fooling groove 231. The anti-fooling convex part 14 is adapted to the anti-fooling groove 231. Thus, through the combined design of the anti-fooling groove 231 and the anti-fooling convex part 14, it avoids the phenomenon that the plugging is prone to errors and cannot be connected. Therefore, only when the anti-fooling convex part 14 is aligned with the anti-fooling groove 231 and then inserted can it be correctly inserted. Moreover, the plugging depth can be controlled by controlling the depth of the anti-fooling groove 231 and the length of the anti-fooling convex part 14 to avoid the phenomenon of over-insertion

[0038] A first snap seat 30 is provided at the upper end of the male terminal body 11, and the first snap seat 30 has a snap hole 31; a second snap seat 40 is provided at the upper end of the female terminal body 21. An elastic arm 41 extends from the upper end of the second snap seat 40 toward the male terminal body 11. A snap portion 42 is provided on the upper side of the elastic arm 41. One end of the elastic arm 41 facing the male terminal body 11 has a pressing portion 43. The pressing portion 43 passes through the snap hole 31 and is exposed outside the first snap seat 30. The snap portion 42 is snapped into the snap hole 31. In this way, when the male connector 10 and the female connector 20 are inserted into each other, the pressing portion 43 can be gently pressed to press down the elastic arm 41, so that the snap portion 42 can smoothly pass through the snap hole 31 and be held in the snap hole 31. When it is necessary to pull out, the pressing portion 43 can be gently pressed to make the snap portion 42 withdraw from the snap hole 31 for quick insertion and extraction, thereby realizing snap connection, which is simple to use, quick to insert and extract, will not loosen or fall off due to aging, and has a longer service life.

[0039] Specifically, in this embodiment, the first snap seat 30 is integrally connected to the upper end of the male terminal body 11, and the snap hole 31 extends in the front-rear direction and penetrates through the front and rear ends of the first snap seat 30. The second snap seat 40 is integrally connected to the upper end of the female terminal body 21; the elastic arm 41 extends integrally backward from the upper end of the second snap seat 40 to above the embedding portion 23 and extends obliquely upward from front to back.

[0040] A first guiding inclined surface 431 is provided at the rear side of the upper end of the pressing portion 43, and the first guiding inclined surface 431 extends obliquely upward from back to front, so that it is more beneficial for the elastic arm 41 to pass through the snap hole 31 through the first guiding inclined surface 431. A second guiding inclined surface 421 is provided at the rear side of the upper end of the snap portion 42, and the second guiding inclined surface 421 extends obliquely upward from back to front, so that the snap portion 42 can be more smoothly snapped into the snap hole 31. An inclined surface 32 extending obliquely downward from front to back is provided at the rear side of the first snap seat 30 to facilitate the downward pressing of the elastic arm 41.

[0041] An elastic sealing ring 50 is provided on one side of the female terminal body 21 facing the embedding portion 23, and the elastic sealing ring 50 is wrapped outside the embedding portion ; one side of the elastic sealing ring 50 is attached to the female terminal body 21, and the outer peripheral side wall of the elastic sealing ring 50 is limited by the inner peripheral side wall of the insertion cavity 13. Here, through the setting of the elastic sealing ring 50, it is prevented that external moisture enters from the gap between the connection parts of the male terminal body 11 and the female terminal body 21, and it can play a good waterproof role.

[0042] Moreover, limiting bumps 232 are respectively protruded on the left and right sides of the outer sidewall of the embedding part 23. The other side of the elastic sealing ring 50 is limited by the limiting bumps 232 towards the side of the female end body 21 to ensure the stable positioning of the elastic sealing ring 50. A third guiding slope extending obliquely upward from back to front is arranged at the rear side of the limiting bump 232 to facilitate the installation of the elastic sealing ring 50. Moreover, in this embodiment, a first annular positioning step 25 is protruded on the outer peripheral sidewall of the side of the female end body 21 facing the embedding part 23. A second annular positioning step 26 is protruded on the outer peripheral sidewall of the female end body 21 on the side away from the embedding part 23. The second annular positioning step 26 is protruded on the periphery of the first annular positioning step 25. One side of the elastic sealing ring 50 is attached to the first annular positioning step 25, and the front sidewall of the male end body 11 is limited by the second annular positioning step 26 to avoid the phenomenon that the male end body 11 is inserted too deeply.

[0043] In summary, the design focus of the present utility model lies in that a first buckling seat is mainly arranged at the upper end of the male end body. The first buckling seat has a clamping hole. A second buckling seat is arranged at the upper end of the female end body. An elastic arm extends towards the male end body at the upper end of the second buckling seat. A buckling part is arranged on the upper side of the elastic arm. One end of the elastic arm facing the male end body has a pressing part. The pressing part passes through the clamping hole and is exposed outside the first buckling seat. The buckling part is clamped in the clamping hole. Thus, when the male end connector and the female end connector are inserted into each other, the pressing part can be lightly pressed to press down the elastic arm, so that the buckling part can smoothly pass through the clamping hole and be clamped in the clamping hole. When it is necessary to pull out, the pressing part can be lightly pressed to make the buckling part withdraw from the clamping hole for quick insertion and extraction, thereby realizing the snap connection, being easy to use, having fast insertion and extraction, not having the phenomenon of loosening or falling off caused by aging, and having a longer service life.

[0044] The above is only a preferred embodiment of the present utility model, and does not impose any limitation on the technical scope of the present utility model. Therefore, any minor modification, equivalent change and modification made to the above embodiments according to the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
