Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of shielding structure on electric connector, especially shielded adapter structure, board end connector and electric connector. BACKGROUND

[0002] The electric drive of new energy vehicle has higher vibration level, the general plastic connector structure has lower strength, and there is a risk of shell rupture, therefore, the connector with metal shell is widely used in this occasion. The metal shell connector generally adopts plug-in form, and the head seat shell is generally made of aluminum alloy or zinc alloy by pressure casting. Compared with the plastic shell, the metal shell needs an elastic shielding layer to connect, so that the head seat shell forms an effective continuous and achieves better shielding effect.

[0003] For example, the Chinese patent with the application publication number CN112086828A discloses a shielding structure and a metal shell connector using the shielding structure, which comprises a plug and a socket with a metal shell, and a shielding structure. The plug-in end of the plug metal shell is provided with a sealing ring. The shielding structure comprises an insulator and a shielding spring. The insulator is usually a plastic part. Since the thin-wall forming process of the plastic part is better than the forming process of the pressure casting shell, the problem of difficulty in mold manufacturing of the metal shell can be solved. The shielding spring is arranged on the insulator. Compared with the existing way of fixing the shielding spring on the metal shell, the problem of large amount of shielding spring shaking can be solved. The insulator can limit the sealing ring in the plug-in direction after being installed on the plug metal shell, without the need for additional parts. The shielding spring contacts the plug metal shell and the socket metal shell respectively after the plug and the socket are plugged in.

[0004] The shielding structure in the above-mentioned disclosure realizes the shielding purpose of the metal shell connector, but in actual use, it is found that when the plug and the socket are plugged in, the shielding spring and the socket metal shell are kept in contact by means of elastic force. The shielding spring of the above-mentioned shielding structure is in contact with the plug metal shell and the socket metal shell in the axial direction at the same time. The tolerance accumulation is large, the reliability of the shielding spring in contact with the plug metal shell and the socket metal shell at the same time is low, and the shielding spring may not be in contact with the plug metal shell and the socket metal shell at the same time, which may lead to shielding failure.
