The female terminal 70 is inserted into the cavity of the second housing 50; the second housing 50 is inserted into the first housing 20; the secondary locking member 10 is disposed between the first housing 20 and the second housing 50 to achieve a secondary locking between the first housing 20 and the second housing 50; the positioning auxiliary member 40 passes through the side of the first housing 20 into the second housing 50 to limit the female terminal 70; the first seal 30 is disposed inside the opening where the second housing 50 is inserted into the first housing 20; the second seal 60 is disposed in the middle of the outer surface of the second housing 50, located between the first housing 20 and the second housing 50.

[0028] Specifically, such as Figures 1-3 As shown, one end of the first housing 20 and the second housing 50 that are inserted into each other has a convex-shaped cavity structure, and the other end has a rectangular cavity structure. The rectangular cavity structure has multiple terminal receiving channels for inserting terminals. The protruding part of the convex-shaped cavity structure has front and rear openings to accommodate the secondary locking member 10 and the locking part on the second housing 50 for engaging with the secondary locking member 10. A third abutment 23 is provided on the inner side of the upper wall of the protruding part of the convex-shaped cavity structure. The third abutment 23 engages with the locking part on the secondary locking member 10 and the second housing 50 to achieve [the desired locking mechanism]. The first housing 20 and the second housing 50 are connected by a secondary latch. The first housing 20 is a rectangular cavity structure with a support rib 21 on the lower side of one end, which facilitates the gripping and insertion of the first housing 20 and the pressing of the secondary latch 10. A first slot 22 is also provided on one side wall of the first housing 20, which is used to latch with the fourth latch 53 of the second housing 50 to realize the latch between the first housing 20 and the second housing 50. An installation opening 24 is also provided on the other side wall of the first housing 20 to provide installation space for the insertion and removal of the positioning auxiliary component 40.

[0029] like Figure 1 , Figure 7-8As shown, the second housing 50 has a rectangular cavity structure. One end of the rectangular cavity structure is used to insert into another female connector (cylinder insert), and this end is provided with multiple terminal receiving channels for accommodating female terminals 70. The upper surface of the other end is elastically provided with a locking part, and the other end is inserted into the convex cavity structure of the first housing 20. The middle part of the outer surface of the second housing 50 is recessed inward to form a second mounting part 55 for installing the second seal 60. A fourth latching member 53 is provided on the side wall of the other end of the second housing 50. The fourth latching member 53 is adapted to the first latching groove 22 to realize a one-time locking between the first housing 20 and the second housing 50. A first mounting part 54 is also provided on the inner side wall of the opening at the other end of the second housing 50 for installing the first seal 30. Two auxiliary component insertion interfaces are also provided on the side wall of the second housing 50 corresponding to the mounting opening 24. The upper and lower auxiliary component insertion interfaces are respectively used for inserting The positioning auxiliary component 40 has an upper plate and a lower plate. Inside the auxiliary component insertion interface, a second slot 51 and a third slot 52 are also provided along the front-rear direction on the inner side of the lower wall of the second housing 50. The second slot 51 and the third slot 52 penetrate the second housing 50, facilitating mold injection and saving mold opening costs. The second slot 51 is used to engage with the third latching member 41 on the positioning auxiliary component 40 to achieve the first engagement of the positioning auxiliary component 40 and the second housing 50, i.e., pre-installation of the positioning auxiliary component 40 and the second housing 50. At this time, the limiting member 43 on the positioning auxiliary component 40 does not restrict the female terminal 70 from exiting. The third slot 52 is used to engage with the third latching member 41 on the positioning auxiliary component 40 to achieve the second engagement of the positioning auxiliary component 40 and the second housing 50, i.e., final fixed installation of the positioning auxiliary component 40 and the second housing 50. At this time, the limiting member 43 on the positioning auxiliary component 40 restricts the female terminal 70 from exiting. Figure 1 As shown, the locking part is inclined upwards from front to back and includes a base plate and two side plates perpendicular to the base plate. The base plate is rectangular and has a fourth slot 57 extending through the end from the front edge to the rear edge. The upper ends of the two side plates extend towards each other to form flanges, and a fourth abutment member 56 is provided between the flanges of the two side plates at the rear end of the locking part. In addition, each terminal receiving channel of the second housing 50 is provided with a downwardly inclined elastic member 58, which abuts against the first abutment part 72 to limit the female terminal 70.

[0030] like Figure 4As shown, the secondary locking member 10 includes a handle and a tongue extending forward from the handle. The upper surface of the tongue is provided with a second latching member 12, a first latching member 11, and a second abutment member 14 from rear to front. A first abutment member 13 is provided on the lower side of the tip of the tongue. The first latching member 11 is a spring-loaded structure extending rearward from the front end. The first abutment member 13 is used to abut against the fourth slot 57. When the cylinder connector is inserted into another female connector, the first latching member 11 can be latched onto the fourth abutment member 56 of the second housing 50. When the latching member of the other female connector pushes up the first abutment member 13, the secondary locking member 10 can be unlocked and pushed inward. Subsequently, the secondary locking member 10 is pushed inward. When the second latching member 12 latches onto the fourth abutment member 56 of the second housing 50, the second abutment member 14 abuts against the third abutment member 23, forming a secondary locking state. The cylinder connector and the other female connector are in an unlockable state.

[0031] like Figure 9 , Figure 10 As shown, the female terminal 70 includes a wire end and a plug-in end. The plug-in end includes a first abutment portion 72 and a second abutment portion 71 that are raised upwards and spaced apart. The first abutment portion 72 and the second abutment portion 71 are respectively adapted to the elastic member 58 and the limiting member 43 to limit the female terminal 70. Preferably, the first abutment portion 72 and the second abutment portion 71 are further provided with reinforcing ribs 73.

[0032] like Figure 1 , Figure 5 , Figure 6 As shown, the positioning auxiliary member 40 is inserted into the second housing 50 from the side and is used to limit the position of the female terminal 70. Specifically, the positioning auxiliary component 40 includes a vertical handle, and an upper plate and a lower plate extending vertically outward from the upper and lower ends of the handle. The upper plate is provided with a plurality of spaced-apart and vertically oriented limiting members 43, which abut against the second abutment portion 71 of the female terminal 70 to restrict the female terminal 70 from exiting the second housing 50. The edge of the upper half is provided with a tightening rib 42. The lower plate is also provided with a third latching member 41 at one end near the handle. The lower plate is also provided with a perforated structure on the plate surface opposite to the third latching member 41. The third latching member 41 is used to latch with the second latching groove 51 or the third latching groove 52 to realize the first or second latching of the positioning auxiliary component 40 and the second housing 50. The perforated structure provides deformation space for the third latching member 41 during the latching process with the second latching groove 51 or the third latching groove 52.
