Abstract: The present disclosure relates to a socket with a fixing device and a charging cabinet for electric vehicles with the socket. The fixing device includes a connection mechanism, which is provided on one side of a mainbody of the socket and is adapted to releasably connect the socket to a mounting object to which the socket is to be mounted by means of a first fixing member, and a pivot mechanism, which is provided between the other side of the mainbody opposite to the connection mechanism and the mounting object, so that the socket is pivotable relative to the mounting object when released from the mounting object. Through the fixing device for the electric vehicle charging gun socket, the charging gun socket can be easily and quickly fixed on a mounting object, such as a charging cabinet, since the number of required fixing parts is reduced.

Abstract: A circuit board for preventing pins of inserting components from being short-circuited during the welding process welding is provided. The circuit board includes an insulating base board comprising a base plate and at least one column of via set on the insulating base board. A plurality of copper foil rings are set on the base plate. An insulating dielectric layer is covered on the base plate and the plurality of copper foil rings. A plurality of solder mask openings are set on the insulating dielectric layer, each solder mask opening is shaped as a circular hole, and is concentric with one via. By covering the insulating dielectric layer on the copper foil rings, an adherence of copper foil and the insulating base board increases, thereby pins of the inserting components will not be easily disengaged from the copper foil in the insulating base board.

Abstract: An exemplary integrated printed circuit board (PCB) includes a main PCB and a peripheral PCB. The main PCB includes a number of general purpose input/output (GPIO) ports and a number of first bonding pads, the bonding pads are located on edges of the main PCB and each GPIO port is electrically connected to one of the first bonding pads. The peripheral PCB includes a receiving space and a number of second bonding pads, the receiving space is used to receive the main PCB, the second bonding pads are located at inner peripheral edges of the peripheral PCB surrounding the receiving space. When the first bonding pads of the main PCB are respectively welded with the second bonding pads, the main PCB and the peripheral PCB are connected to each other to form the integrated PCB. An electronic device incorporating an integrated PCB is also provided.

Abstract: A wave soldering carrier includes a base plate and a fixing member positioned on the base plate. The base plate defines a receiving recess and a number of through holes communicating with the receiving recess. The receiving recess receives a circuit board. The through holes are arranged and shaped corresponding to a number of electronic components on the circuit board. The fixing member includes a shaft including a fixing shaft fixed to the base plate and a restricting shaft extending from an end of the fixing shaft. A diameter of the restricting shaft is greater than that of the fixing shaft, thereby forming a step. The fixing member further includes a rotatable member rotatably connected to the fixing shaft and sandwiched between the shoulder and the base plate. The rotation member is rotatable to a preset position, where a distal end of the rotatable member firmly contacts the circuit board.
