As an exemplary embodiment, refer to Figures 1 to 4 As shown in , the insulating seat 100 may be provided with a first through hole for the connector 200 to pass through, and the insulating seat 100 may be installed on the cabinet. In this way, the connector 200 is inserted into the first through hole, and the insulating seat 100 can be arranged between the connector 200 and the cabinet to provide an insulating effect between the connector 200 and the cabinet.
[0032] The insulating seat 100 can be partially extended out of the cabinet body. In this way, it is not only conducive to the connection between the connector 200 and the external circuit, but also can ensure that there is a certain distance between the external circuit and the battery cabinet, and the insulating seat 100 is sleeved on the outside of the connector 200 in this distance, so the insulating seat 100 can play an insulating role between the external circuit and the battery cabinet, that is, the above design can ensure the insulation distance between the external circuit and the battery cabinet, and then ensure the insulation effect between the external circuit and the inside of the battery cabinet.
[0033] In the battery cabinet provided in the present disclosure, the insulating seat 100 can be arranged in any suitable manner. As an exemplary embodiment, refer to Figures 1 to 4 As shown in , the insulating seat 100 can be constructed as an electric porcelain bottle. In this way, the shed structure of the electric porcelain bottle can increase the creepage distance of the insulating seat 100 per unit length. In other words, the shed structure of the electric porcelain bottle can shorten the layout length of the insulating seat 100 along its own axial direction, so as to achieve the effect of saving space.
[0034] In the battery cabinet provided by the present disclosure, in order to ensure the insulation effect of the power porcelain bottle, as an exemplary embodiment, the creepage distance of the power porcelain bottle is not less than 250 mm.
