[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figures 1 to 3 The utility model provides a connector that is easy to use, including a connector body 1 and a connector sub-body 2 connected to the end of the connector body 1. A sintered filter disc 7 and a dislocation disc 8 are arranged in the connector sub-body 2. The dislocation disc 8 is located on one side of the sintered filter disc 7, and the dislocation disc 8 is provided with a plurality of dislocation holes 9. The dislocation holes 9 are staggered with the through holes 3 arranged on the side of the connector sub-body 2, which can better block the entry of water. The sintered filter disc 7 is connected with a locking nut 6 for positioning the sintered filter disc 7. The locking nut 6 can be rotatably connected to the connector sub-body 2. The locking nut 6 is pressed against the sintered filter disc 7. In combination with the use of the step surface 11, the sintered filter disc 7 can be locked and fixed, thereby improving the stability of the sintered filter disc 7, facilitating assembly, and having high flexibility.

[0019] The end of the joint body 1 is provided with a threaded interface, which matches the internal thread 13 provided in the joint sub-body 2. The joint body 1 can be rotated to screw the threaded interface into the joint sub-body 2, so as to facilitate docking with the joint sub-body 2.

[0020] The joint body 1 is provided with an annular groove 5, and the annular groove 5 is sleeved with a rubber ring 4. When the joint body 1 and the joint sub-body 2 are connected, the rubber ring 4 can improve the sealing performance of the connection between the two to prevent the invasion of external impurities and water stains.

[0021] An internal thread 12 is provided inside the connector body 2, and a locking nut 6 is connected to the internal thread 12. The locking nut 6 is an annular structure, and an external thread is provided on the outside, and the external thread matches the internal thread 12, so as to facilitate the connection between the locking nut 6 and the connector body 2.
