Abstract: A vacuum switching valve and a suction system having the same. The vacuum switching valve comprises: a valve body, comprising a first end and a second end, the second end being provided with an air inlet, an air outlet and a through hole; a valve element movably arranged in the valve body; a cylinder, the cylinder being connected to the first end and the valve element, the cylinder drives the valve element to move in the valve body, to close or open the air inlet; a stopper passing through the through hole, the stopper comprising a third end and a fourth end, the third end being connected to the valve element, the fourth end being located on the side of the through hole away from the valve element.

Abstract: An over-temperature protection system has a control board mounted in a charging device and a temperature sensor mounted in a charging plug. A switch is coupled on a power circuit of the charging plug and controlled by the control board. When the charging plug is connected to a power supply and the charging device begins a charging operation, the control board periodically receives temperature information of the charging plug sensed by the temperature sensor. When the control board determines that the temperature of the charging plug is abnormal, the switch is open to interrupt the power circuit so as to stop the charging operation for ensuring safety of the charging device.

Abstract: A split-type power optimization module for solar module strings of a solar panel includes multiple power optimization module blocks. Each power optimization module block uniquely corresponds to one of multiple solar module strings on a solar panel and has a single-chip processor, a string connection port, and a power output port. The string connection port is connected to the single-chip processor and an adjacent solar module string. The power output port is connected in series to the power output port of an adjacent power optimization module block. Accordingly, each power optimization module block performs maximum power point tracking for the connected solar module string to lower the power loss of each solar module string and ensure string-level maximum power optimization.

Abstract: A split-type power optimization wiring box assembly for solar module strings of a solar panel includes a solar panel and multiple wiring boxes mounted on the solar panel. Each wiring box has a power optimization module block mounted therein. The solar panel has multiple solar module strings with each adjacent two of the multiple solar module strings connected through a corresponding wiring box. A power output terminal of each solar module string is connected to the power optimization module block inside a corresponding wiring box, such that the multiple solar module strings can be connected in series. The power optimization module block inside each wiring box performs Maximum Power Point Tracking on the connected solar module string for fulfilling power optimization on the basis of individual solar module string, thereby reducing the power loss of the solar module strings to achieve maximum power optimization of the solar panel.

Abstract: A fixing structure of electronic components has a first substrate, at least one second substrate, at least one electronic component, and at least one fixing mechanism. Each second substrate has at least two first pins to electrically connect to the first substrate. Multiple second pins formed on a side surface of the electronic component are electrically connected to the second substrate. The at least one fixing mechanism covers the at least one electronic component and the at least one second substrate. A first mounting part and a second mounting part respectively extend downward from opposite sides of the at least one fixing mechanism for clamping the electronic component and the second substrate so that the at least one electronic component and the at least one second substrate are erectly mounted on the first substrate. Thus, more electronic components are allowed to be erectly mounted on the first substrate.

Abstract: A protecting cap structure of a charging gun has a cover, a push plate, a fixing seat, at least one first resilient element, and a gland. The push plate is moveably mounted in a containing groove of the cover. The fixing seat, the first resilient element, and the gland are mounted in the containing groove. The first resilient element and the gland are respectively mounted on both sides of the push plate, and the first resilient element abuts and pushes the front side of the push plate. The protecting cap structure not only improves water resistance and dust resistance by the gland which is propped by the resilient element when the cover covers the plug of the charging gun, but also is easy to use because the resilient elements push forward the cover when the cover is to be removed.
