[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Example

[0020] See also Figures 1-4 The utility model provides a technical solution: a board-mounted connector, comprising a socket connector 1 and a plug connector 2, wherein the plug connector 2 is detachably inserted into the interior of the socket connector 1, and two fixing components 4 are symmetrically arranged on the outside of the socket connector 1;

[0021] The fixing assembly 4 includes a fixing box 41, which is fixed to the outside of the socket connector 1. A fixing rod 42 is fixedly connected to the inside of the fixing box 41, and a lock buckle 43 is slidably connected to the outside of the fixing rod 42. A spring 44 is sleeved on the outside of the fixing rod 42 and located between the lock buckle 43 and the inner wall of the fixing box 41. A reset rod 45 is slidably connected to the inside of the fixing box 41, and the reset rod 45 is fixedly connected to the side of the lock buckle 43 away from the spring 44. Two fixing buckles 3 are fixedly connected to the outside of the plug connector 2, each fixing buckle 3 is respectively inserted into the corresponding fixing box 41, and the fixing buckle 3 is interlocked with the lock buckle 43. With the cooperation of the fixing assembly 4 and the fixing buckle 3, the traditional plug-in installation method can be replaced, which can effectively prevent the plug connector 1 from being detached from the socket connector 2 and improve the stability during use.

[0022] Furthermore, a guide groove 5 is provided on one side of the inner wall of the socket connector 1, and a positioning protrusion 6 is fixedly connected to the outer side of the plug connector 2, and the positioning protrusion 6 is inserted into the inside of the guide groove 5. By providing the guide groove 5 inside the socket connector 1 to cooperate with the positioning protrusion 6 on the plug connector 2, the position can be corrected during assembly to prevent misaligned installation and damage to the pins caused by shaking during installation.

[0023] Furthermore, an annular groove 7 is provided on the top of the socket connector 1, and a sealing gasket 8 is provided inside the annular groove 7. A sealing frame 9 is fixedly connected to the bottom of the plug connector 2. The sealing frame 9 is inserted into the annular groove 7 and contacts the sealing gasket 8, which can improve the sealing effect of the board-mounted connector after assembly and prevent dust from entering.

[0024] Furthermore, a plurality of guide grooves 10 are symmetrically provided on the outer side of the socket connector 1, which can increase the air contact area of the connector and improve the heat dissipation effect.

[0025] In summary, when installing the board-mounted connector, insert the plug connector 2 into the socket connector 1, and ensure that the positioning bump 6 is inserted into the guiding groove 5 to prevent the plug connector 2 from shaking or misaligning during insertion, which may cause pin damage. After the plug connector 2 is fully inserted into the socket connector 1, the sealing frame 9 at its top is inserted into the annular groove 7, and the gasket 8 inside the annular groove 7 is squeezed to improve the sealing effect between the socket connector 1 and the plug connector 2 and prevent dust from entering. At the same time, the two fixing buckles 3 on the outside of the plug connector 2 are respectively inserted into the corresponding fixing boxes 41. When the fixing buckle 3 enters the fixing box 41, it squeezes the locking buckle 43 and drives the locking buckle 43 to slide on the fixing rod 42 and squeeze the spring 44. After the fixing buckle 3 moves down to the lower side of the locking buckle 43, the spring 44 drives the locking buckle 43 to reset, forming an interlocking structure with the fixing buckle 3, thereby firmly locking the plug connector 2 above the socket connector 1 and preventing the separation of the socket connector 1 and the plug connector 2 caused by equipment vibration.
