Detailed Description
The following describes the embodiments of the present invention in detail. It is to be understood that the description of the embodiments herein is for purposes of illustration and explanation only and is not intended to limit the invention.
In the present invention, the use of the terms of orientation such as "upper and lower" in the case where no description is made to the contrary generally means the orientation in the assembled and used state. "inner and outer" refer to the inner and outer contours of the respective component itself.
The utility model discloses in provide an electric motor car wisdom fire safety circuit interface that charges, as shown in fig. 1, electric motor car wisdom fire safety circuit interface that charges includes insulating casing 1, sets up insulating sliding plate 2 and ejection mechanism in the reason casing 1, the sliding plate 2 with insulating casing 1's inner wall slidable connection, be provided with electrically conductive clamping piece 4 on the sliding plate 2, electrically conductive clamping piece 4 includes left electrically conductive clamping piece 42 and right electrically conductive clamping piece 41, takes place the short circuit in order to prevent to participate in between 6, the sliding plate 2 must adopt insulating material preparation to form, for example pottery, rubber etc..
The ejection mechanism comprises a spring 31, a connecting part 32 and a connecting wire 33, wherein the connecting part 32 is arranged on the sliding plate 2, one end of the spring 31 is connected with the sliding plate 2, the other end of the spring 31 is connected with the top wall of the insulating shell 1, the spring 31 has the tendency of pushing the sliding plate 2 away from the top wall of the insulating shell 1, one end of the connecting wire 33 is connected with the connecting part 32, and the other end of the connecting wire 33 is connected with the top wall of the edge shell 1. The connecting wire 33 may be rigid or flexible, such as a steel wire, or flexible such as a rope.
