A wireless charging power bank includes a first shell, a second shell, a heat dissipation shell, a battery and a coil. The first shell is connected with the second shell to form an accommodating space, and the battery is arranged inside the accommodating space. The heat dissipation shell is connected with the first shell or the second shell, a part of the heat dissipation shell is arranged on the outermost side of the wireless charging power bank, and the coil is electrically connected with the battery for wirelessly charging an external device; and the coil abuts against the heat dissipation shell, and the heat dissipation shell is used for conducting heat generated by the coil to the outside.

A door for an energy storage system includes: a first door frame; a second door frame facing the first door frame; a door channel between the first door frame and the second door frame; an inlet hole passing through the first door frame and configured to allow a flame or gas to be introduced into the door channel; a discharge hole passing through the second door frame and configured to allow a flame or gas to be discharged from the door channel; and a blocking member facing the discharge hole and configured to block a flame that is discharged from the discharge hole from passing therethrough.

A connection component for an electrical conductor includes: at least one component body formed, at least in portions, by a plastics material. The plastics material includes a flame retardant. The plastics material is free of perfluorinated or polyfluorinated alkyl compounds. The flame retardant includes a polymer structure of the plastics material and/or an additive incorporated in the polymer structure of the plastics material that substitutes for the perfluorinated or polyfluorinated alkyl compounds, and/or an outer layer formed on the component body.

Systems and apparatus for blocking access to high temperature components include a computer component, and a shape memory alloy (SMA) interlock thermally coupled to the computer component, wherein the SMA interlock is configured to prevent access to the computer component when a temperature of the computer component exceeds a threshold temperature.

Equipment including a casing wherein are located: a box; a first loudspeaker disposed inside the box, the first loudspeaker being arranged to broadcast sounds outwards from the casing; a main electronic board placed in the casing outside of the box and on which is mounted, at least one power supply module producing a first power supply voltage; a connecting device passing through the wall of the box; a secondary electronic board inside the box on which is mounted, at least one first amplifier connected to the first loudspeaker, the secondary electronic board being connected to the main electronic board via the connecting device to power the first amplifier with the first voltage.

Providing cooling airflow through an electronic device is described. The electronic device incudes a heat source, an airflow enclosure, an insulation layer, and a directional structure. The airflow enclosure is on a first side of the insulation layer and the heat source is on a second side of the insulation layer. The insulation layer includes at least one directional opening that is adjacent to the heat source. The directional structure is positioned on the second side of the insulation to provide a directed cooling airflow path from the at least one directional opening to the heat source.

Devices and methods for detecting and reporting a battery tamper event with regard to an intrinsically-safe or explosion-proof device while the device is located in a hazardous environment. The device may include a location sensor for determining that the device is in a hazardous location. While in the hazardous location, the device may detect an open enclosure event using a sensor and, if so, it may monitor for detection of a battery tampering event. The battery tampering event may include battery replacement or battery charging. The battery tamper event may be reported to a remote server over a wireless channel when it occurs.

An explosion-proof housing, which forms an interior for accommodating components that can form ignition sources. The housing has a first housing part with a first section which has a first face, and a second housing part with a second section which has a second face, the first section and/or the second section being a section of a wall, the first face and the second face delimiting an intermediate region. The first section and the second section are pressed against each other with elastic deformation of the wall section so that the intermediate region is geometrically closed in a flameproof manner by the elastic deformation of the wall section. The invention also relates to a method for producing an explosion-proof connection between a first section of a first housing part with a first face and a second section of a second housing part with a second face of a housing, at least one of the sections being a section of a wall. The invention also relates to a further method for producing an explosion-proof connection between a first section of a first housing part with a first face and a second section of a second housing part with a second face of a housing, at least one of the sections being a section of a wall.

A sealing structure for an explosion-proof over-temperature and over-current protector, comprising an over-temperature and over-current protector, an explosion-proof pouring compound, a switch contact protective housing, and an externally protective case; wherein the externally protective case is a relatively closed case which wraps up the explosion-proof pouring compound completely so as to prevent the explosion-proof pouring compound from being exposed to the ultraviolet light, thus the protector can be used in the environment having ultraviolet light; the sealing structure further comprises a cable electrically connected with the over-temperature and over-current protector, wherein the externally protective case is provided with a cable hole having an inward rounded edge.
