The utility model provides a sealed connector, comprising: a plug connector body; one end of the plug connector body forms a plug end, and a sealing ring is integrally formed on the plug end in an injection molding manner;

The technical solution of the hermetic plug connector according to the present invention will be described below by way of example with reference to an embodiment.

As shown in fig. 1, the hermetic connector of the present embodiment includes: a plug body 10. Wherein, one end of the connector body 10 forms a plug end 11, and the plug end 11 is integrally formed with a sealing ring 20 by injection molding. Thus, the sealing ring 20 is integrally injection-molded on the insertion end 11, and the subsequent independent installation of the sealing ring 20 is avoided. And the sealing ring 20 formed by integral injection molding and the inserting end 11 can be tightly matched, so that the falling of the sealing ring 20 is effectively sealed.

In one embodiment, the connector body 10 is a plastic member integrally injection molded; the sealing ring 20 is a silicone member that is integrally injection molded. In addition, to facilitate the integral injection molding of the sealing ring 20, the plugging end 11 of the plug body 10 is provided with an annular groove suitable for the integral injection molding of the sealing ring 20.

Further, the seal ring 20 has the following structural features: a plurality of sealing convex rings 21 are arranged on the peripheral side surface of the sealing ring 20, and the sealing convex rings 21 are arranged side by side. In this manner, the seal ring 20 has a larger sealing area. In one embodiment, the number of the sealing rings 21 is three. In addition, the outer peripheral side faces of two sides of the plurality of sealing convex rings 21 are arranged in an outward inclined mode, and the outer peripheral side faces which are arranged in an inclined mode are beneficial to achieving interference fit in the inserting process.

In order to facilitate the insertion of the sealed connector of this embodiment, the peripheral edge 110 of the end face of the insertion end 11 and the peripheral side surface 111 thereof are both guide surfaces arranged obliquely along the insertion direction, and the inclination of the peripheral edge 110 of the end face is greater than that of the peripheral side surface 111 on one side thereof.

The sealing type connector clip also has an anti-falling structure 30 which can realize locking after the connector clip is plugged, thereby effectively avoiding the falling of the connector clip.

Specifically, the anti-drop structure 30 includes: anticreep back-off 31 and anticreep barb 32, anticreep back-off 31 are a plurality of, and a plurality of anticreep back-offs 31 distribute on the periphery side 111 of plug connector body 10 rear end, and one side of placing in plug connector body 10 is erect through a connection to anticreep barb 32.

In one embodiment, any of the anti-drop back-offs 31 is a right angle trapezoid; the end surface 110 of the right trapezoid is coplanar with the stepped surface at the rear end of the connector body 10. Thus, after the insertion, the inclined surface of the anti-drop back-off 31 can be abutted against the corresponding wall surface to realize the anti-drop.

Further, the anti-drop barb 32 includes: a spring arm 321, and a separation preventing hook 322 disposed on the top surface of the spring arm 321. The rear end of the elastic arm 321 is connected with the connecting frame, gaps are formed between two sides of the elastic arm 321 and the connecting frame, the anti-disengaging hook 322 is a right-angle trapezoid body, and the inclined plane of the right-angle trapezoid body is arranged along the plugging direction.

Thus, during plugging, the elastic arm 321 deforms and presses down, so that the anti-falling hook 322 can be clamped into the corresponding anti-falling groove; after the insertion is completed, the elastic arm 321 rebounds to allow the rear end face of the anti-drop hook 322 to abut against the corresponding wall surface to prevent the drop. In addition, the top surface of the elastic arm 321 is further provided with a limiting block 323 located behind the anti-drop hook 322, and the limiting block 323 can play a limiting role after being inserted in place.
