Abstract: A charging socket integrated with an electronic lock. The charging socket includes a socket housing and a socket assembly. The socket assembly is provided within the socket housing. The socket assembly includes a printed circuit board. The electronic lock is electrically connected to the printed circuit board of the socket assembly.

Abstract: A temperature detection module includes a terminal locking component lockable to a charging terminal and insertable into a mounting hole of a housing of a charging device together with the charging terminal. The terminal locking component locks the charging terminal into the housing. A temperature sensor is installed in the terminal locking component and inserted into the mounting hole of the housing together with the terminal locking component. The temperature sensor detects a temperature of the charging terminal.

Abstract: An electrical connection assembly includes a charging terminal, a power transmission component, a heat dissipation block, and a fastener. The charging terminal has a first connection end. The power transmission component includes a metal busbar with a second connection end. The fastener fastens the first connection end, the second connection end, and the heat dissipation block together. The heat dissipation block is in thermal contact with the first connection end or is simultaneously in thermal contact with the first connection end and the second connection end.

Abstract: The present disclosure pertains to the field of biomedical materials, and in particular relates to a medical hydrogel, a preparation method and uses thereof, and a kit for preparing the medical hydrogel. The medical hydrogel of the present disclosure comprises a hydrogel skeleton, and a chelating agent chelated to the hydrogel skeleton; wherein the hydrogel skeleton comprises a polymer that is formed by the bonding of a polyethylene glycol derivative I having a structure shown in Formula (I) and a polyethylene glycol derivative II having a structure shown in Formula (II) and has multiple “long arms”. After tannic acid and/or citric acid as a chelating agent chelates with the hydrogel skeleton, a medical hydrogel can be obtained, which has good bacteriostatic properties, mechanical properties, adhesion properties, low swelling properties, and controllable gel formation rate and degradation rate.
