Problems solved by technology

[0003] In the operation process of connecting the shore power cable to the DC power supply and the battery, the traditional connection method uses terminal wiring and bolt fastening. This method is simple, but there are some inherent defects: 1. If the voltage of the battery pack is high, charging When the current required is large, the risk factor of personnel operation is high; 2. If the number of cables is large, the weight of a single cable is large and the length is long, the workload required for personnel operation is large; 3. The space required for operation is large, Difficult to construct in a narrow area

Embodiment Construction

[0042] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0043] Such as figure 1 As shown, the DC power supply is connected to the plug assembly through the shore power cable, and the battery pack is connected to the socket assembly through the battery cable. When the plug assembly and the socket assembly are plugged and docked, an electrical path is formed, and the connection between the DC power supply and the battery can be realized. It can be used for DC power to charge the battery pack.

[0044] A high-current DC connection device, including a plug assembly, a socket assembly and a connection box, and the plug assembly and the socket assembly corre...

Abstract

The invention discloses a high-current direct-current connecting device which comprises a plug assembly, a socket assembly, and a connecting box used for fixing the socket assembly and connected with a cable of a battery pack. The plug assembly and the socket assembly are in one-to-one correspondence. The plug assembly comprises a plug shell, a jack contact piece, a pressing plate, a compression nut and a connecting nut. The socket assembly is fixed into the connecting box, and comprises a socket shell, a second sealing washer, a pin contact piece and a socket insulation sleeve. Quick and safe butt joint between a direct-current power supply and the battery pack is realized under a direct-current high-current condition, and the purpose of charging the battery pack through the direct-current power supply is achieved.

Description

technical field [0001] The invention relates to a direct current power supply connection device, in particular to a large current direct current connection device. Background technique [0002] Ships that use direct current as the main power source or emergency power source are usually equipped with one or more battery packs. The battery packs supply power to the ship's electrical consumers, so these batteries must be recharged frequently. When the ship is docked at the dock or docked for maintenance, an onshore DC power supply (called "shore power") is usually used to connect to the battery pack through the shore power cable for charging. [0003] In the operation process of connecting the shore power cable to the DC power supply and the battery, the traditional connection method uses terminal wiring and bolt fastening. This method is simple, but there are some inherent defects: 1. If the voltage of the battery pack is high, charging When the current required is large, th...
