Abstract: A terminal having a stamping elastic sheet structure, including a mounting base (1) and an outer elastic sheet structure (2). An end of the outer elastic sheet structure (2) is connected to an end of the mounting base (1). The mounting base (1) and the outer elastic sheet structure (2) are formed separately, and the outer elastic sheet structure (2) is formed by stamping. The terminal having the stamping elastic sheet structure is formed by assembling a stamping elastic sheet and a mounting base that are separately machined and manufactured, instead of integral machining, so as to greatly reduce the cost of the terminal, reduce the machining time, ensure a sufficient contact between the elastic sheet and a conductive portion of a mating terminal, and meet the mechanical demand and the temperature rise requirement of a charging system.

Abstract: The present disclosure discloses a temperature-measurement terminal structure, which belongs to the technical field of the manufacturing of electric energy transmission devices, including a terminal (1) and a temperature sensor (2). The terminal (1) includes an embedding groove (11) with an inner contact surface (111). The temperature sensor (2) is at least partially disposed in the embedding groove (11) and has a temperature measurement surface (21) attached to the inner contact surface (111). In the present disclosure, by disposing the temperature sensor in the groove, the temperature sensor can be more firmly attached to the terminal, so that the temperature signal collected by the temperature sensor is closer to the actual temperature change, with small error. By connecting the plugging member with the temperature sensor, the temperature sensor can be conveniently installed before being connected to a wire, so as to meet the requirements of complicated installation environments.

Abstract: The present disclosure discloses an automobile charging device and a preparation method thereof. The automobile charging device includes a charging connector, a rear housing, and a cable. The charging connector includes a connecting portion, a first end of the rear housing is connected to the connecting portion, a second end of the rear housing is provided with a wire-through hole, the cable enters the rear housing through the wire-through hole and is connected to the charging connector, a protective portion is disposed outside the rear housing, and the protective portion at least wraps the rear housing therein. The automobile charging device charges an electric automobile through connection between the charging connector and the electric automobile, in which the cable enters the rear housing through the wire-through hole of the rear housing and is connected to the charging connector. And the wrapping of the protective portion achieves the water-proof sealing of a connection region between the cable and the rear housing. Further, the rear housing is provided so that the protective portion may be a hollow structure, thereby reducing the volume and weight of the protective portion, thus ensuring both the water-proof sealing performance and weight of the automobile charging device.
