The needle bar 200 is located in the main body 100 and is connected with the insertion channel in a clamping manner, the contact 210 of the needle bar 200 is connected with the elastic part 220, the tail part is connected with the elastic body 300, and both ends of the needle bar are elastic, so that the needle bar can be better adapted to a cable terminal, and the contact performance is still better in a vibrating environment. Poor contact caused by vibration is avoided, the power-off phenomenon is eliminated, and the stability of the electric connection of the adapter is ensured.

Referring to fig. 3, a connecting hole 232 is formed at the tail of the rod 230, and the elastic body 300 is nested and adapted with the connecting hole 232. It can be understood that the tail of the rod body 230 of the first needle bar 201 is provided with a first connecting hole, the first elastic body 301 is matched with the first connecting hole, and similarly, the tail of the rod body 230 of the second needle bar 202 is provided with a second connecting hole, and the second elastic body 302 is matched with the second connecting hole. It will be appreciated that the tail of the beam 230, i.e., the end of the beam 230 that is distal from the contact 210.

Referring to fig. 2 and 3, a waterproof sealing ring 500 is disposed between the nut 400 and the second connecting portion 120. The waterproof sealing ring 500 is arranged to improve the waterproof performance, so that the adapter is convenient to use outdoors.

Referring to fig. 2 and 3, the main body 100 is provided with a limiting groove 121 adapted to the waterproof sealing ring 500. The limiting groove 121 is arranged to prevent the waterproof sealing ring 500 from sliding, so that the waterproof performance is ensured.
