In the above embodiment, the male plug a of the automobile is plugged into the plug-in port (not labeled in the drawing) so that the male plug a is abutted against the female plug 120, thereby electrically connecting the male plug a and the female plug 120 to each other. If the user backs a car and keeps away from the charging pile without removing the male plug a, the tensile force borne by the connecting piece 220 exceeds the working range under the tensile force of the male plug a. The connector 220 is disengaged from the base 110 such that the male plug a pulls the shield mount 210 and the connector 220 together out of the base 110. Thereby avoiding serious accident loss caused by pulling the charging pile.
It should be emphasized that the connecting piece 220 is used for connecting the protection seat 210 and the base 110, and when the tensile force born by the connecting piece 220 exceeds the working range, the connecting piece 220 is completely (or partially) separated from the base 110, so that the protection seat 210 and the base 110 are far away from each other. While the connectors 220 satisfying the above conditions may satisfy the requirements. For example, the connecting member 220 may be broken under a pulling force exceeding the working range, and the protecting seat 210 and the base 110 may be separated from each other without limitation after the connecting member 220 is broken.
In some embodiments, the connecting piece 220 includes a connecting piece 221 and a plurality of clamping portions, the connecting piece 221 is fixedly connected to the protection seat 210, the plurality of clamping portions are arranged along the circumferential direction of the connecting piece 221, the clamping portions and the base 110 clamp the outer edge of the connecting piece 221, and when the tensile force born by the connecting piece 220 exceeds the working range, the connecting piece 221 deforms to be separated from the clamping of the clamping portions and the base 110.
In the above embodiment, when the tensile force borne by the connecting member 220 exceeds the working range, the connecting piece 221 is deformed and bent, so that the connecting member 220 is forcibly separated from the clamping portion and the clamping portion of the base 110.

By passing the guard bolt through the notch 2211 and screwing the guard screw hole (not shown), the contact area between the guard bolt and the connection piece 221 can be increased, so that the clamping portion and the base 110 can clamp the connection piece 220 more stably.
It will be appreciated that any embodiment that can secure the connection tab 221 and the guard base 210 is possible, such as welding or clamping. In a specific embodiment, the connecting piece 221 is provided with a plurality of fixing screw holes 2212, the protection seat 210 is provided with a plurality of matching holes 212 corresponding to the fixing screw holes 2212 one by one, and the protection seat 210 further includes a plurality of fixing bolts 213 corresponding to the matching holes 212 one by one, and the fixing bolts 213 pass through the matching holes 212 and are screwed with the fixing bolts 213.
In the above embodiment, since the connection piece 221 and the protection seat 210 are connected by a bolt, the connection implementation of the bolt can connect the connection piece 221 and the protection seat 210 more firmly than the connection mode of the clamping connection. In contrast to welded connection, the bolted embodiment allows for replacement of the connection piece 221, so that a new connection piece 221 can be replaced after the connection piece 221 has been deformed.
In a specific embodiment, the base 110 includes a base body 111 and a transition seat 112, the female plug 120 is mounted on the base body 111, the transition seat 112 is detachably mounted on the base body 111, and the connection piece 220 is connected to the transition seat 112. The connection is made by means of the transition seat 112 and the connection piece 220, while the base body 111 is fitted with the female plug 120. When the connecting member 220 is deformed in tension, the transition seat 112 directly receives the force of the connecting member 220, and if the transition seat 112 is damaged due to the tension, the transition seat 112 can be replaced. The problem that the whole base 110 is difficult to repair due to the damage of the pulling force is avoided.
In the above embodiment, the base 110 further includes a gasket 113, and the gasket 113 is sandwiched between the base body 111 and the transition seat 112. So that sealability between the base body 111 and the transition seat 112 can be secured, thereby protecting the electrical components in the base 110.
