Energy storage device and power consuming apparatus

A power consuming apparatus comprising an energy storage device supplying power to the power consuming apparatus, wherein the energy storage device comprises:

• a housing having an opening, wherein the housing defines an accommodating cavity;
• an electrode assembly accommodated inside the accommodating cavity;
• an end cap assembly covering the opening;
• a pole assembly arranged in the end cap assembly, the pole assembly comprising a flange;
• a lower plastic part arranged between the electrode assembly and the end cap assembly;
• and
• a current collecting member flush with and attached to a surface of the lower plastic part away from the end cap assembly, wherein the current collecting member comprises an adapter and an insulator, the adapter comprises a first surface and a second surface that are arranged in a thickness direction of the adapter, the first surface is located on a side of the adapter that faces an electrode assembly of the energy storage device, the second surface is located on a side of the adapter that faces away from the electrode assembly of the energy storage device, the adapter comprises a first connecting portion, a fuse portion and a second connecting portion in a length direction of the adapter, the first connecting portion of the current collecting member is electrically connected to the pole assembly, the second connecting portion of the current collecting member is electrically connected to the electrode assembly, and the fuse portion is connected between the first connecting portion and the second connecting portion;
• a ratio of a width of the fuse portion in a width direction of the adapter to a width of the first connecting portion and a ratio of the width of the fuse portion in the width direction of the adapter to a width of the second connecting portion each are in a range from ⅙ to ⅘;
• and the first connecting portion is provided with first corners at an end of the first connecting portion close to the second connecting portion, the second connecting portion is provided with second corners at an end of the second connecting portion close to the first connecting portion, the insulator is provided with a first protective portion, a second protective portion and a third protective portion in the length direction of the adapter, the first protective portion covers the first corners, the second protective portion covers the second corners, the third protective portion is connected to the first protective portion and the second protective portion, the third protective portion covers a first surface of the fuse portion of the adapter, and a second surface of the fuse portion is at least partially exposed from the insulator;
• in the thickness direction of the adapter, a stepped recess is defined in a surface of the insulator close to the second surface of the adapter, the stepped recess comprises a first recess and a second recess that are arranged opposite to each other in the width direction of the adapter, the fuse portion is arranged between the first recess and the second recess, a side of the first recess close to the flange and a side of the second recess close to the flange define a connecting line L, and an end of the flange adjacent to the fuse portion extends beyond the connecting line L towards the insulator.
