The positioning cavity 15 may extend from the rear end 14 of the front housing 1 to the front end 12 and terminate in a stop wall 151.
Referring to fig. 1, the female terminal assembly 2 may include a sheath 21, and a front end of the sheath 21 may have a stop surface 211. As shown in fig. 1, the female terminal assembly 2 may further include a female terminal 23, a first portion 231 of the female terminal 23 may extend out of the sheath 21 from a stop surface 211 at a front end of the sheath 21, and a second portion (not shown in fig. 1) may be located within the sheath 21. Referring to fig. 1, the female terminal assembly 2 may also include a wire 25. The wire 25 may be electrically connected to the female terminal 23, for example, a first portion of the wire 25 (not shown in fig. 1) may be located within the sheath 21 and electrically connected to a second portion of the female terminal 23 located within the sheath 21. As shown in fig. 1, the second portion 251 of the lead 25 may extend from the rear end of the sheath 21.
During installation of the female terminal assembly 2 from the rear end 14 of the front housing 1 to the front housing 1, the first portion 231 of the female terminal 23 of the terminal assembly 2 may enter the positioning cavity 15 of the front housing 1 from the rear end 14 of the front housing 1 and further into the terminal receiving cavity 13. Referring to fig. 3, fig. 3 is a schematic view showing a state in which the front housing 1 and the female terminal assembly 2 are mounted together, as seen from the rear end direction, according to an embodiment of the present utility model.
When the female terminal assembly 2 is mounted into the front housing 1, the first portion 231 of the female terminal 23 may be at least partially located within the terminal receiving cavity 13 of the front housing 1 and the outer surface of the first portion 231 may contact the inner wall 131 of the terminal receiving cavity 13, the sheath 21 of the female terminal assembly 2 may be at least partially located within the positioning cavity 15 of the front housing 1 and the stop surface 211 of the front end of the sheath 21 may contact the stop wall 151 of the front housing 1. The contact of the inner wall 131 of the terminal receiving chamber 13 with the outer surface of the first portion 231 of the female terminal 23 prevents the front housing 1 and the female terminal assembly 2 mounted together from rocking relative to each other in the circumferential direction. Contact between the stop wall 151 of the front housing 1 and the stop surface 211 of the front end of the sheath 21 of the female terminal assembly 2 may prevent further movement of the female terminal assembly 2 toward the front end 12 of the front housing 1.
Referring to fig. 1, the connector 100 may further include a rear housing 3. The rear housing 3 may be formed by injection molding and may be fixedly connected to the front housing 1 and the female terminal assembly 2 during the injection molding. For example, the front housing 1 and the female terminal assembly 2 may be first mounted together to form a pre-mount (as shown in fig. 3), then the pre-mount is placed in an injection mold for forming the rear housing 3, and finally the rear housing 3 is formed by injection molding. In forming the rear housing 3, the material constituting the rear housing 3 may be first filled in a flowing state in a cavity portion between the front housing 1 and the female terminal assembly 2 (the cavity portion may include the opening 152 in the positioning cavity 15, the void 154 as shown in fig. 3) and a cavity portion between the injection mold and the pre-mount (not shown in the drawings), and then the material may be cured to form the rear housing 3 in a solid state. The cured rear housing 3 may further secure the front housing 1 and the female terminal assembly 2 mounted together to each other.
Referring to fig. 1, the rear case 3 may have a front positioning portion 31, and the front positioning portion 31 may be located at the front end of the rear case 3.

As shown in fig. 1, the front positioning portion 31 may have a main body portion 311. The body portion 311 may be configured to fill a void 154 between the sidewall 153 of the positioning cavity 15 of the front housing 1 and the sheath 21 of the female terminal assembly 2. Referring to fig. 1, the front positioning portion 31 may further have a protrusion 313, and the protrusion 313 may protrude outward from the outer surface of the body portion 311. The protrusion 313 may be configured to fill the opening 152 on the sidewall 153 of the positioning cavity 15 of the front housing 1. The number and shape of the protruding portions 313 may be set to be compatible with the number and shape of the opening portions 152 described below.
Referring to fig. 2, the sidewall 153 of the positioning chamber 15 of the front case 1 may have an opening 152. As shown in fig. 2, the sidewall 153 of the positioning chamber 15 may have four opening portions 152 thereon, and each opening portion 152 may be configured as a T-shaped opening. Accordingly, the front positioning portion 31 of the rear case 3 may have four protrusions 313, and each protrusion 313 may be configured as a T-shaped protrusion for filling a corresponding T-shaped opening. The engagement between the T-shaped opening and the T-shaped protrusion may prevent the front case 1 and the rear case 3 from being separated from each other, thereby fixedly connecting the front case 1 to the rear case 3.
