The base 200 is provided with a receiving portion 201 for contacting the bottom surface of the second contact piece 1022. Since the second contact 1022 is connected to the first contact 1021, the overall height of the second contact 1022 is smaller than that of the first contact 1021, specifically, the first contact 1021 can contact the inner bottom surface of the base 200, and the second contact 1022 cannot contact the inner bottom surface of the base 200, so that the second contact 1022 is in a suspended state. When the second contact 1022 in the suspended state receives an external force from the electrical appliance plug in the vertical direction, the second contact 1022 moves toward the inner bottom surface of the base 200, so that the second contact 1022 is bent in the vertical direction, and the elastic direction of the second contact 1022 is toward the first contact 1021, and the second contact 1022 is often difficult to recover when being bent in the vertical direction, thereby easily causing damage. The supporting portion 201 can abut against the bottom surface of the second contact piece 1022, so that the movement of the second contact piece 1022 in the vertical direction is limited, and the second contact piece 1022 is prevented from being bent in the vertical direction to cause damage. In this embodiment, each of the supporting portions 201 is divided into two parts and spaced apart by a certain distance, so as to be capable of respectively contacting with two sides of the bottom surface of the second contact piece 1022, and better support the second contact piece 1022 without making the volume of the supporting portion 201 too large.

Further, the receiver 201 is provided with an abutting portion 2011 for abutting against a side surface of the second contact piece 1022. Insert the plug with the electrical apparatus in the plug bush, can make the distance between second contact piece 1022 and the first contact piece 1021 increase equally, if long-time after using, the distance between second contact piece 1022 and the first contact piece 1021 can not recover gradually, also can lead to the contact failure of socket and plug, consequently often base 200 all can set up a cavity that can hold the plug bush just, avoids plug bush portion 102 deformation excessively can not recover. Since the supporting portion 201 needs a certain area to have sufficient stress strength to support the second contact piece 1022, the second contact piece is easily bent after being stressed, and there is no practical effect. However, the cavity for accommodating the plug housing portion 102 is also increased, and in order to avoid excessive deformation of the plug housing portion 102 due to the increased cavity, the support portion 201 is provided with an abutting portion 2011 which abuts against the side surface of the second contact piece 1022 on the side away from the first contact piece 1021, thereby limiting the deformation range of the plug housing portion 102 to a certain extent.

In addition, in the present embodiment, the inner wall of the base 200 is provided with a boss portion 202 for abutting against the stopper portion 103. During installation, the plug bush can be installed in the base 200 only by abutting the limiting portion 103 and the protruding portion 202, and a certain false installation prevention effect is achieved. More importantly, after the limiting part 103 is abutted against the boss 202, the boss 202 has a certain supporting effect on the whole plug bush, so that the plug bush is further improved to be more stably arranged in the base 200, and cannot be deformed greatly easily when stressed.

The remaining features and operating principle of this embodiment are consistent with embodiment 3 or 4.
