This invention relates to the field of battery technology, specifically to a battery. The battery includes a casing and an electrode assembly, the electrode assembly being located within a receiving space formed by the casing. The casing includes a first through-hole, and the battery further includes a connecting mechanism connected to a first tab assembly, the connecting mechanism passing through the first through-hole. The connecting mechanism includes a conductive element and an insulating element, the conductive element being connected to the first tab assembly, and the insulating element being located between the casing and the conductive element. At least one of the interfaces between the conductive element and the insulating element and between the insulating element and the casing forms a bonding region. The bonding region includes a first surface of the conductive element facing the insulating element and / or a second surface of the casing facing the insulating element, the first surface and / or the second surface including a plurality of recesses, the orthographic projection of the insulating element covering the recesses, and the insulating element including protrusions embedded in the recesses. The battery of this invention is applicable to batteries of various thicknesses and can improve the sealing performance and connection strength of the connecting mechanism.

The utility model relates to the technical field of foundation pit construction equipment, and discloses a supporting system for displacement control of a half-cover excavation foundation pit, which comprises two cross beams, each cross beam is provided with a supporting frame, the supporting frames are U-shaped, and the two supporting frames are connected in a sliding manner; a hydraulic cylinder is arranged on the inner side of one supporting frame, a one-way positioning rack is arranged on the hydraulic cylinder, the telescopic end of the hydraulic cylinder is connected with the other supporting frame, a supporting frame is movably arranged at one end of the hydraulic cylinder, an adjusting plate is hinged to the other end of the hydraulic cylinder, and the bottom end of the adjusting plate is hinged to the telescopic end of the hydraulic cylinder. A positioning ratchet is elastically arranged on the support frame; a connecting rod is hinged to the supporting frame and hinged to the adjusting plate. The hydraulic cylinder supporting device can assist the hydraulic cylinder in positioning and supporting and effectively share part of counter-acting force acting on the hydraulic cylinder, the stability of a supporting system is guaranteed, meanwhile, potential threats to the hydraulic cylinder are reduced, and the service life of the hydraulic cylinder is guaranteed.
