The invention discloses an electrochemical device and an electronic device. The electrochemical device comprises a pole piece and a pole lug, wherein the pole piece comprises a current collector, a first active material layer and a first insulating layer; the current collector comprises a first part of a first region, a second region and a third region, the first region is provided with a first active material layer, and the second region is provided with a first insulating layer. The orthographic projection of the second region at least partially surrounds the orthographic projection of the first part of the third region in the thickness direction of the current collector, and the first region and the second region are arranged in the length direction of the current collector. According to the pole piece disclosed by the invention, the exposed conductive area is relatively small, so that the safety risk can be reduced, for example, the risk of short circuit is reduced when an electrochemical device is punctured.

The utility model discloses a special safety component for building first floor sewage pipe installation reinforcement, include: sewage pipe support piece (1), sewage pipe support piece (1) is used for supporting sewage pipe (4), sewage pipe limiting piece (2), sewage pipe limiting piece (2) is connected to the both sides of sewage pipe support piece (1) symmetry or asymmetry, wherein, one end of each sewage pipe limiting piece (2) is connected with the outer wall of sewage pipe support piece (1), and the other end of each sewage pipe limiting piece (2) is connected with the steel mesh (7) on reinforced terrace (6) through limiting rope (5) and is connected as a whole or is directly anchored into plain concrete terrace. The utility model simple structure, novel and reasonable design can effectively reduce the risk of sewage pipe settlement cracking or joint drop due to backfill soil settlement during the use of sewage pipe, and when installing, it is simple and quick, and can be directly installed on the construction site without the aid of other tools, saving time and being efficient.
