Abstract: The invention proposes a kind of bending bolt type anti-loosening nut, which relates to the technical field of mechanical fastening. It comprises an upper nut and a lower nut, the upper nut and the lower nut are stacked on the outside of the bolt and used to tightly connect the bolt to the connecting piece, the lower nut is arranged close to the connecting piece, the upper nut is arranged on the outer end surface of the lower nut; the adjacent end between the upper nut and lower nut is provided with an inclined surface, the inclined surface is inclined towards the interior of the upper nut, so that an inclined plane angle with deformation space between the upper nut and lower nut is formed; the invention achieves the effect of preventing nut loosening, is low in price, easy to manufacture, and suitable for small or miniature anti-loosening nuts.

Abstract: Embodiments of this application provide an information indication method and apparatus. The method includes: A CP indicates, to a UP by using first information, a maximum number of EHC contexts that can be established by the UP for UE, a DRB of the UE, or a PDU session of the UE in a downlink direction, so that the UP can establish a proper number of EHC contexts for the UE, the DRB of the UE, or the PDU session of the UE in the downlink direction based on the maximum number. This resolves a problem that a UP in an access network device in a split architecture cannot establish a proper number of EHC contexts for the UE because the UP does not know a capability of the UE.

Abstract: A battery module includes a battery, a structure positioned at least partially around the battery, a temperature sensor positioned between the battery and the structure, and a directing portion directing a temperature detection range of the temperature sensor toward the battery.
