Referring to the first to eighth figures, the connector assembly of the first embodiment of the present invention is used for direct insertion of a stepping motor 300 for an automobile. The connector assembly includes a circuit board 200 and is mounted to the circuit board 200. Connector 100.

The circuit board 200 includes a first surface 201 , a second surface 202 , and an opening 203 extending through the first surface 201 and the second surface 202 . In this embodiment, the first surface 201 and the second surface 202 are respectively an upper surface and a lower surface of the circuit board 200; and the opening 203 is located at an intermediate position of the circuit board 200 and is closed, in other embodiments. The first and second surfaces 201, 202 may also be the lower surface 202 and the upper surface 201 of the circuit board 200, respectively; and the opening 203 may also be located at the edge of the circuit board 200 and open.

The connector 100 is mounted in the opening 203 of the circuit board 200 and includes an insulative housing 1 received in the opening 203 and a terminal 2 disposed on the insulative housing 1 .

The insulative housing 1 extends in the longitudinal direction and is provided with an abutting surface 11 exposed on the upper side of the circuit board 200, a mounting surface 12 disposed opposite to the mating surface 11 and exposed on the lower side of the circuit board 200, and a plurality of through-station The mating surface 11 and the mounting surface 12 are provided to receive the terminal groove 13 of the insertion portion 301 of the stepping motor 300. The terminal slots 13 are arranged along the longitudinal direction of the insulative housing 1, and each of the terminal slots 13 is provided with a pair of positioning slots 131 along lateral sides perpendicular to the longitudinal direction. The insulative housing 1 further includes a retaining groove 14 spaced apart from the terminal slot 13 . The retaining slot 14 is recessed upwardly from the mounting surface 12 of the insulative housing 1 and does not extend upwardly through the mating surface 11 .

The terminal 2 is assembled from the mounting surface 12 of the insulative housing 1 into the insulative housing 1 and includes a contact portion 21 disposed on the insulative housing 1 and a mounting portion 22 located below the mounting surface 12 . The contact portion 21 includes a pair of clamping portions 211 extending into the terminal groove 13 and spaced apart, and the clamping portion 211 is received in the positioning groove 131 to prevent the stepping motor 300 that is butted against it from being inserted. The nip portion 211 is disposed at a lateral interval to sandwich the insertion portion 301 of the stepping motor 300 inserted into the terminal slot 13.
