The second coupling portion 1222 is used to electrically connect the grounding spring 122 to the grounding screw 121, and in one embodiment of the present invention, the grounding screw 121 is directly connected to the second coupling portion 1222 in contact.

It should be noted that, the second coupling portion 1222 is directly connected to the ground screw 121 in contact, and it should be understood that, when the lamp connector 1 is installed, the ground screw 121 is directly installed on the second coupling portion 1222, or the ground screw 121 is clamped on the second coupling portion 1222 through other conductive connecting members, but the second coupling portion 1222 is directly connected to the ground screw 121 in contact regardless of whether the ground screw 121 is directly installed on the second coupling portion 1222 or clamped on the second coupling portion 1222 through other conductive connecting members.

The second coupling portion 1222 includes a first elastic arm 1222-a, the first elastic arm 1222-a includes a first fixing piece 1222-a1 fixed on the first coupling portion 1221, and a first suspending piece 1222-a2 extending from the first fixing piece 1222-a1 to a direction close to the ground screw 121, so that after the ground screw 121 penetrates the mounting surface 1101 through the first connecting hole 1101-a, the screw of the ground screw 121 contacts the first suspending piece 1222-a2 and is pressed by the first suspending piece 1222-a2, thereby making the ground screw 121 and the ground spring 122 conduct.

It should be noted that the first suspending piece 1222-a2 may be a rigid piece that does not bend or a flexible piece that allows a certain amount of bending deformation, as long as the grounding screw 121 is in contact with the first suspending piece 1222-a2 and is pressed by the first suspending piece 1222-a 2; preferably, the first suspension piece 1222-a2 of the embodiment of the present invention is a flexible member allowing a certain bending deformation, and after the grounding screw 121 penetrates through the mounting surface 1101, the first suspension piece 1222-a2 can press the screw rod of the grounding screw 121, so that the first suspension piece 1222-a2 has good contact performance and electrical conductivity with the grounding screw 121.

As shown in fig. 8 and 9, the first fixing tab 1222-a1 extends from the first coupling portion 1221 along a direction perpendicular to the extending direction of the first coupling portion 1221 to support the first suspension tab 1222-a 2.

It should be noted that the distance between the end of the first bending edge 1221-b4 close to the ground line and the end of the second bending edge 1221-b5 close to the ground line is the minimum engaging distance of the first barb 1221-b, and the distance between the end of the first bending edge 1221-b4 away from the ground line and the end of the second bending edge 1221-b5 away from the ground line is the maximum engaging distance of the first barb 1221-b; the width of the first card slot 1102 is greater than the minimum clamping distance and less than the maximum clamping distance, so that on one hand, the width of the first card slot 1102 is prevented from being too small, and the first bending edge 1221-b4 and the second bending edge 1221-b5 of the first barb part 1221-b cannot be mounted to the notch of the first card slot 1102; on the other hand, the first barb portions 1221-b are prevented from being loosened at the notches of the first card slot 1102 due to the excessive width of the first card slot 1102, and the first barb portions 1221-b cannot be clamped on the first card slot 1102.
