Optionally, the limiting member 1211 includes a second limiting portion 1214, and when the limiting member 1211 is located at the abutting portion 1001, the second limiting portion 1214 is disposed opposite to the mounting surface 1110 at an interval and is used for abutting against the circuit board mounted at the mounting portion 1111 to limit the movement of the circuit board in a direction perpendicular to the mounting surface 1110.

Through setting up spacing portion 1214 of second in order to restrict the circuit board at the ascending removal of perpendicular to installation face 1110 side to the realization is detained and is pressed spacingly to the circuit board, thereby when realizing detaining the circuit board and pressing to installation position 1111 on, electric connector 1300 is inseparabler with the circuit board electricity is connected, thereby avoids contact failure.

The second position-limiting portion 1214 is configured to abut against the circuit board in a direction perpendicular to the mounting surface 1110 when the position-limiting member 1211 is located at the abutting position 1001, so as to limit the movement of the circuit board in the direction perpendicular to the mounting surface 1110.

Specifically, the second limiting portion 1214 of the limiting member 1211 extends toward the mounting position 1111 to abut against the circuit board in a direction perpendicular to the mounting surface 1110.

Optionally, at least two of the mounting locations 1111 are provided with alignment members 1500 extending along the first direction at both sides opposite in the second direction, and the positioning member 1200 is located between the alignment members 1500 at both sides of the at least two mounting locations 1111 opposite in the second direction to align the circuit board with the positioning member 1200 when the circuit board is mounted.

By providing the aligning member 1500 to achieve coarse alignment of the circuit board mounting position 1111 at the time of mounting the circuit board, and by using the aligning member 1500 and the positioning member 1200 to cooperate with each other, after the coarse alignment of the circuit board mounting position 1111, precise alignment of the circuit board is achieved by using the positioning member 1200.

Wherein the alignment member 1500 may be a rod-shaped member extending in the first direction.
