In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0029] like Figures 1 to 6 As shown, this embodiment provides a connector, which includes a connector terminal 1 and a plastic shell 201. The connector terminal 1 is formed by stamping and bending a sheet metal body. The connector terminal 1 includes a first terminal portion 101, a bending portion 102 and a second terminal portion 103, wherein the first terminal portion 101 has a first surface 111 along the width direction and a first side surface 121 perpendicular to the first surface 111 and along the thickness direction, and a first protrusion point 131 is provided on one side of the first side surface 121.

[0030] A positioning pin 151 extends downward from the other side of the first side surface 121 and is perpendicular to the first terminal portion 101. The positioning pin 151 has a second surface 161 along the width direction and a second side surface 171 perpendicular to the second surface 161 and along the thickness direction. A second protrusion 181 is provided on one side of the second side surface 171. The positioning pin 151 also has a guiding function.

[0031] Furthermore, the orientation of the second protrusion point 181 is opposite to that of the first protrusion point 131. Since the orientation of the first protrusion point 131 is opposite to that of the second protrusion point 181, when the connector terminal 1 is inserted into the plastic shell 201, the first protrusion point 131 and the second protrusion point 181 will be embedded in the plastic shell 201, providing retaining forces in opposite directions to prevent the connector terminal 1 from loosening or falling off from the plastic shell 201.

[0032] Furthermore, a welding portion 141 extends from the first side surface 121 of the first terminal portion 101. The direction in which the welding portion 141 extends is opposite to the direction of the first protrusion 131.

[0037] Among them, a first slot 209 and a positioning slot 210 are opened in the installation slot 208, the first slot 209 is connected to the positioning slot 210, the first slot 209 includes a slot bottom wall, a slot left wall, a slot right wall and a slot rear wall, the first protrusion 131 abuts against the slot rear wall, the positioning slot 210 includes a first slot side wall 215, a second slot side wall 212 and a slot bottom wall 213, the first slot side wall 215 is parallel to the second slot side wall 212, the slot bottom wall 213 is perpendicular to the first slot side wall 215 and the second slot side wall 212, and the second protrusion 181 abuts against the first slot side wall 215. A stop 214 extends from the second slot sidewall 212. The stop 214 is perpendicular to the second slot sidewall 212, and the stop portion 112 abuts against the top surface of the stop 214. The connection between the second slot sidewall 212 and the stop 214 is formed into an arc. An insertion hole 215 is also defined within the mounting slot 208. The insertion hole 215 communicates with the inner cavity 202, and the second terminal portion 103 is inserted into the inner cavity 202 through the insertion hole 215.
