Abstract: An electrochemical device includes an electrode assembly and a housing for accommodating the electrode assembly. The housing includes a first housing body and a second housing body fixedly connected to the first housing body. A notch is provided on at least one of the first housing body or the second housing body. The electrode assembly includes a tab. The tab protrudes out of the housing from the notch. The notch is filled with a sealing material.

Abstract: The invention is KVM extender receiving end provided with switch device. It includes video decoder, mouse and keyboard encoder and switch device, the input end of video decoder is connected to switch device. The output end of mouse and keyboard encoder is connected to switch device. Advantages: it will separate the intranet and the internet of the department. It will not only prevent hacker's attack but also effectively prevent internal staff from network leak. It can place two computers into the computer room, which is far away from personal office station and save a lot of office space for each office worker.

Abstract: The present disclosure provides a pressing device which includes: at least two floating heads which are arranged side by side; a positioning member connecting with each floating head and defining a position of each floating head; a cover plate positioned above each floating head; and elastic members, each elastic member being provided between the cover plate and the corresponding floating head so as to make the cover plate slide up and down relative to each floating head. The pressing device can be adapted to a step type cell or a step type battery having a certain tolerance in thickness and can ensure that every step surface of the step type cell or the step type battery is uniformly pressed, thereby improving the quality of the battery.
