Patent Description:
Connectors, also known as plug connectors, sockets and joints, are devices that connect two active devices to transmit current or signals.

Connectors used for energy storage have lower requirements than connectors used in new energy electric vehicles. They do not require waterproofing and electromagnetic shielding, but they also have relatively high requirements for structure and safety, requiring the plug to be firmly plugged into the socket.

The traditional high-voltage connector for energy storage is not provided with a fastening-locking structure, and the male terminal and the female terminal of the connector are easily loosened after the male terminal is inserted in the female terminal.

The plug of the traditional high-voltage connector for energy storage is not provided with a hand-held pluggable portion, which results in no unstressed part on the plug. It is extremely difficult and time-consuming and laborious for the male terminal of the connector to insert in and separate from the female terminal.

Both of the male and female terminals of the traditional high-voltage connector for energy storage adopt a non-cylindrical structure, and neither of the male and female terminals have a circular cross-section. The male terminal and the female terminal cannot form a rotating shaft after the male terminal is inserted in the female terminal, and the entire plug cannot be rotated <NUM>° along the rotating shaft to adjust the outgoing direction of the wire.

The plug and wire of the traditional high-voltage connector for energy storage are integrally formed, which is costly, requires accurate wire length, and is inconvenient for the after-sales service.

The socket of the traditional high-voltage connector for energy storage is not provided with an anti-electric shock cap, or the pin is higher than the socket body, or the crown spring in the hole of the plug is higher than the plug body, which cannot be ensured that the pins of the socket are not contacted by the charged body, that the pins of the positive and negative sockets are not short-circuited by the charged body, and that the human body is protected from electric shock.

In view of this, it is indeed necessary to optimize the socket and plug to provide an anti-electric shock high-voltage connector for energy storage with a fastening-locking structure, and a plug having a structure with a hand-held plug-in position, capable of being rotated <NUM>° to adjust the outgoing direction of the wire, and separated from the wire.

<CIT> discloses a high-current and high-protection connection system for an energy storage system. <CIT> discloses a high-voltage and high-current connector with the direction being selectable. <CIT> discloses a high-voltage and energy-storage rapid-insertion connector.

The present application provides, by optimizing the socket and plug, a high-voltage connector for energy storage with a fastening-locking structure, and a plug having a structure with a hand-held plug-in position, capable of being rotated <NUM>° to adjust the outgoing direction of the wire, and separated from wire.

The protective back cover has two fastening methods. The first fasting method is that the ridge portion is fastened by hand tightening, and the second fastening method is that the hexagonal portion is fastened with a wrench or other tools. When the protective back cover is fastened, the first fastening method, namely, hand-tightening, is preferred, and the second fastening method, namely, tool-fastening is used when the hand-tightening is not too tight.

In one embodiment, the plug is separated from a wire. The cost of the connector is low, the length of the wire is not necessary very accurate, and the after-sales service is more convenient. The wiring cup opening of the plug is used for connecting wires. Firstly, the wire is inserted into the wiring cup opening, then the wire production equipment or hydraulic tools are used to press the connection cup opening into a hexagon, and then the connection cup opening is wrapped with the insulating tape or heat shrinkable tubing to make the connection cup opening and the wire tightly integrated, that is, the plug and the wire are integratedly formed.

The hole of the plug is inserted into the pin of the socket and is engaged with the pin of the socket in an interference fit through the crown spring, which is an electrical connection, otherwise, is unplugging.

The pressing buckle of the plug is buckled to the fastening ring of the socket through the buckle, which is a fastening buckle, otherwise, is a fastening separation. The locking slider of the plug pushes from the plug to the socket, which is locking buckling; otherwise, is locking separation.
