An electric connector, includes an insulated housing, a male plug at one end of the housing and a female socket on the opposite end of the housing. The male plug and female socket respectively have an electrode and an electrode slice which is electrically connected with a pair of the male plug and female socket inside the housing. The female socket has an opening adaptive to accommodate the male plug and enable a connection between the electrode of the male plug and that of the female socket. The invention also provides a movable device using the electric connector. According to the invention, a plurality of movable devices with a charging unit can be charged simultaneously and the charging process can be simplified, thereby improving the utilization and safety of the movable devices and lowering the cost of maintenance.

Electrical connector and movable device using the same

A frame structure includes a frame body and an auxiliary frame fixedly connected to the frame body. The frame body has a front bracket and a frame base. The lower end of the front bracket does not connect with the frame base. The upper end portion of the auxiliary frame is connected to the front bracket of the frame body, and the lower end of the auxiliary frame is connected to the frame base at the rear of front wheels of the frame. A trolley with the frame structure can prevent it from leaning forward or overturning, which increases security and stability.

Frame structure and trolley using frame structure

An apparatus and method for charging movable devices like carts or trolleys. Each movable device includes a charging unit and a charging connector coupled to the charging unit, including a male plug at one end, a female socket at the other end, and two electrodes interconnected. When the devices are in a queue, the male plug of the connector of a device in the rear is connected to the female socket of the same in the front so that a plurality of movable devices are connected to each other in tandem and charged simultaneously. The method includes connecting the plurality of devices in tandem with the respective connectors so that the devices can be charged simultaneously. A plurality of movable devices can be charged simultaneously and the charging process can be simplified, thereby improving the utilization and safety of the movable devices and reducing the cost of maintenance.
