The first limiting member 2 is used to limit the displacement of the plug terminal 3 along the second direction, and the second limiting member 4 is used to limit the position of the plug terminal 3 along the first direction, the second direction being perpendicular to the first direction.

[0023] In this embodiment, the first direction refers to the left-right direction of the housing 1, the second direction refers to the front-back direction of the housing 1, and the third direction refers to the up-down direction of the housing 1.

[0024] In this embodiment, the plug terminal 3 is directly installed in the mounting cavity 17. The first limiting member 2 and the second limiting member 4 limit the plug terminal 3 in the mounting cavity 17 to prevent the plug terminal 3 from coming out of the mounting cavity 17.

[0025] In this embodiment, the limiting of the plug terminal 3 can be achieved without setting a shield and a glue core, which facilitates installation and saves production costs.

[0026] In one embodiment, the first limiting member 2 is detachably connected to the first through hole 23. The first limiting member 2 includes a stop plate 5 that spans across the first through hole 23. The side of the stop plate 5 facing the insertion section 10 is a stop surface.

[0031] In this embodiment, the first receiving groove 6 extends in the vertical direction, and the end of the plug segment 10 away from the connecting segment 11 can be inserted into the first receiving groove 6. In the second direction, the groove sidewall of the first receiving groove 6 limits the plug segment 10. In the first direction, the groove bottom wall of the first receiving groove 6 abuts against the plug segment, preventing the plug terminal 3 from moving towards the first through hole 23, thereby preventing the plug terminal 3 from detaching from the housing 1 through the first through hole 23.

[0032] In one embodiment, the plug segment 10 is further provided with a guide block 28 on one side facing the stop plate 5. The guide block 28 extends in a third direction and is plugged into the first receiving groove 6.

[0033] In this embodiment, a guide block 28 is provided on the end face of the plug segment 10 away from the connecting segment 11.

[0034] In this embodiment, the guide block 28 extends in the vertical direction.

[0035] In this embodiment, the width of the guide block 28 in the second direction is less than that of the plug segment 10.

[0036] In this embodiment, the top of the first receiving groove 6 is provided with an opening, and the plug terminal 3 can be installed in the first receiving groove 6 from top to bottom through the opening, so that the side of the plug section 10 away from the connecting section 11 abuts against the stop plate 5, which facilitates installation.

[0037] In one embodiment, the stop plate 5 is provided with a support plate 7, and the support plate 7 is provided with a second receiving groove 8. The second receiving groove 8 extends along a first direction, and one side of the insertion segment 10 in the width direction is inserted into the second receiving groove 8.

[0038] In this embodiment, the support plate 7 is connected to the bottom of the stop plate 5.

[0039] In this embodiment, the second receiving groove 8 extends in the left-right direction, the bottom of the plug segment 10 is inserted into the second receiving groove 8, and the side wall of the second receiving groove 8 contacts the side of the plug segment 10 in the thickness direction, thereby limiting the plug segment 10 and preventing the plug segment 10 from moving in the second direction.

[0040] In one embodiment, the second limiting member 4 is used to limit the displacement of the plug terminal 3 from the first side 26 toward the second side 27.

[0041] In this embodiment, the second limiting member 4 includes a first connecting part 13 and a first spring piece part 14, and the first connecting part 13 is connected to the inner wall of the mounting cavity 17.

[0042] The first spring plate portion 14 is inclined, and the end of the first spring plate portion 14 near the second side 27 is connected to the first connecting portion 13. The distance between the end of the first spring plate portion 14 away from the second side 27 and the insertion section 10 is less than the distance between the end of the first spring plate portion 14 near the second side 27 and the insertion section 10.

[0043] The insertion section 10 is provided with a first locking hole 12, which penetrates the insertion section 10 along the second direction, and the first spring piece 14 engages with the first locking hole 12.

[0044] In this embodiment, the first card hole 12 passes through the insertion segment 10 along the second direction.

[0045] In this embodiment, the distance between the end of the first spring piece 14 away from the second side and the insertion segment 10 is less than the distance between the end of the first spring piece 14 near the second side 27 and the insertion segment 10.

[0046] In this embodiment, the first spring piece 14 is inserted into the first locking hole 12, such that the end of the first spring piece 14 away from the second side 27 abuts against the side wall of the first locking hole 12 facing the second side 27. Since the first connecting part 13 is installed on the inner wall of the mounting cavity 17, the first connecting part 13 cannot move. Therefore, under the blocking of the first spring piece 14, the insertion section 10 cannot move towards the second side 27, thereby limiting the insertion section 10 between the stop plate 5 and the first spring piece 14.

[0047] In this embodiment, the plug-in terminal cannot move in the first direction due to the limitation of the stop plate 5 and the first spring piece 14.

[0050] The inner wall of the third receiving groove 20 is provided with a slot 22, and the second spring piece 16 engages with the slot 22.

[0051] In this embodiment, the opening of the third receiving groove 20 faces the first through hole 23.

[0052] In this embodiment, a slot 22 is provided on the inner wall of the third receiving groove 20 facing the insertion section 10.

[0053] In this embodiment, the distance between the end of the second spring portion 16 away from the second side surface 27 and the insertion segment 10 is greater than the distance between the end of the second spring portion 16 near the second side surface 27 and the insertion segment 10.

[0054] In this embodiment, the second connecting part 15 enters the third receiving groove 20 through the first through hole 23 and the slot. When the first spring piece 14 moves to the position of the first locking hole 12, the first spring piece 14 swings towards the direction of the insertion section 10, so that the first spring piece 14 enters the first locking hole 12 and abuts against the first locking hole 12. At this time, the second spring piece 16 swings away from the insertion section 10, so that the end of the second spring piece 16 enters the locking groove 22. The end of the second spring piece 16 abuts against the inner wall of the groove facing the second side 27 of the locking groove 22, preventing the second connecting part 15 from disengaging from the third receiving groove 20.

[0055] In one embodiment, the distance between the first connecting portion 13 and the plug terminal 3 is smaller than the distance between the second connecting portion 15 and the plug terminal 3, a guiding notch 21 is provided on the third receiving groove 20, and the first connecting portion 13 is clipped into the guiding notch 21.

[0058] In this embodiment, the first connecting portion 13 forms a Π-shaped structure.

[0059] In this embodiment, the first connecting portion 13 clipped into the guiding notch 21 can play a guiding role when the second connecting portion 15 enters the third receiving groove 20, which facilitates assembly.

[0060] In one embodiment, a receiving hole 19 is provided on the inner cavity wall of the mounting cavity 17, the plugging section 10 is penetrated through the receiving hole 19, and the inner hole wall of the receiving hole 19 is in contact with the outer surface of the plugging section 10.
